Although this review uses the MASLD-MASH-fibrosis/cirrhosis-HCC sequence as a mechanistically informative model, the gut-liver-immune framework is also relevant, with important etiology-specific differences, to alcohol-associated liver disease (ALD), chronic hepatitis B virus (HBV) infection, chronic hepatitis C virus (HCV) infection, and mixed-etiology liver disease. Across these contexts, hepatocyte lipotoxicity or viral/alcohol-induced injury, mitochondrial stress, endotoxemia, altered bile-acid signaling, fibrotic remodeling, and immune exhaustion progressively reshape the hepatic microenvironment toward tumor-permissive inflammation and immune escape. We integrate transcriptomic, single-cell, spatial, microbial, and metabolomic evidence to define stage- and etiology-dependent immunometabolic states. Particular emphasis is placed on microbial metabolites, including short-chain fatty acids, secondary bile acids, and tryptophan-derived indoles, which engage host receptors such as FFAR2/3, GPR109A, FXR, TGR5, AhR, and PXR to influence lipid metabolism, epithelial barrier integrity, cytokine programs, epigenetic remodeling, and antitumor surveillance. We further discuss how sex, baseline microbiome composition, hepatic zonation, and preclinical model selection influence disease trajectories and therapeutic responses. By focusing on the gut microbiota-metabolism-immunity axis, this review provides a systems-level framework for biomarker discovery, risk stratification, precision nutrition, and rational combination therapies. Targeting the coordinated interplay among diet, microbiota, metabolism, immunity, and the hepatic spatial niche may help intercept chronic liver disease before malignant transformation and improve therapeutic responses in established HCC."},{"quadrant":"Run1_Eval1_synthesis","attempt":1,"quote":"dietary BAs can attenuate these detrimental effects by modulating metabolic pathways and the gut microbiota composition.","status":"PASS","error":"","abstract_text":"ID: 42415055\nTitle: Dual regulation of bile acids: ameliorating hepatic glycolipid disorders and restoring intestinal health in HFHC-challenged Yellow River carp (Cyprinus carpio L.).\nAbstract: This study was designed to investigate how three distinct bile acids (BAs) modulate glycolipid metabolic disorders and hepatointestinal injury induced by excessive intake of lipids and carbohydrates in Yellow River carp (Cyprinus carpio L.) and elucidate the underlying mechanisms involved. Here, the fish were randomly assigned to five groups: a control group (CON), a high-fat high-carbohydrate diet (HFHC) group, a HFHC + 300 mg/kg chenodeoxycholic acid (CDCA) group, a HFHC + 300 mg/kg ursodeoxycholic acid (UDCA) group and a HFHC + 300 mg/kg hyodeoxycholic acid (HDCA) group. The results revealed that the serum triglyceride, glucose, and total cholesterol levels were significantly elevated in HFHC-fed fish, accompanied by increased glutamic-oxaloacetic transaminase (GOT) and glutamic-pyruvic transaminase (GPT) activities in the serum and hepatopancreas. However, dietary supplementation with bile acids in the HFHC diet significantly improved these negative changes. Analysis of BA-glycolipid metabolism-related gene expression and enzyme activities in the hepatopancreas revealed that CDCA and HDCA inhibited gluconeogenesis (FBPase/PEPCK/G6Pase) and lipogenesis (SREBP-1/FAS), while promoting glycogen accumulation (genes and glycogen levels) and fatty acid β-oxidation (PPARα) via activation of the FXR (farnesoid X receptor) /SHP (small heterodimer partner) pathway. In contrast, dietary UDCA supplementation increased intestinal TGR5 (takeda G protein-coupled receptor 5) expression and suppressed the activities of two key gluconeogenic enzymes, PEPCK and G6Pase. Additionally, dietary BAs supplementation alleviated HFHC diet-induced intestinal inflammation by inhibiting the NF-κB (Nuclear Factor κB) pathway. Bile acids relieved gut dysbiosis, improved microbial alpha diversity and community structure, and enriched beneficial bacteria including Cetobacterium somerae. These microbial changes eventually modulated host substance synthesis and metabolism. HE staining showed that HFHC diet caused hepatopancreatic lesions and intestinal morphological damage in Yellow River carp, which were effectively alleviated by bile acid addition. In conclusion, HFHC diets disrupt fish glycolipid metabolism and impair hepato-intestinal health in Yellow River carp, whereas dietary BAs can attenuate these detrimental effects by modulating metabolic pathways and the gut microbiota composition."},{"quadrant":"Run1_Eval1_synthesis","attempt":1,"quote":"Activation of FXR has emerged as a promising therapeutic strategy for treating metabolic dysfunction-associated steatohepatitis (MASH) or other FXR-dependent diseases.","status":"PASS","error":"","abstract_text":"ID: 42421220\nTitle: Discovery of Novel Isoxazole-Based FXR Agonists Containing a 1,2,4-Oxadiazol-5(4H)-one Ring.\nAbstract: Farnesoid X receptor (FXR) is a member of the ″metabolic″ subfamily of nuclear receptors and is mainly present in the liver and intestines, playing a crucial role in bile acid homeostasis, inflammation, and fibrosis. Activation of FXR has emerged as a promising therapeutic strategy for treating metabolic dysfunction-associated steatohepatitis (MASH) or other FXR-dependent diseases. Here, we report our work on the discovery of a series of isoxazole-based FXR agonists containing an oxadiazolone ring. 40 compounds were designed and synthesized based on scaffold hopping and bioisostere strategies.

In 964 women, we measured markers of gut epithelial dysfunction (fatty acid binding protein 2, FABP2) and gut microbial antigen translocation (soluble CD14, sCD14) using sera collected before, during and after the MT. Multivariable mixed effects regressions fit piece-wise linear models to repeated FABP2 or sCD14 measures relative to time from final menstrual period (FMP). Covariates were age at FMP, race/ethnicity, and BMI. FABP2 and sCD14 did not change significantly until 2.5 years pre-FMP. At that point, FABP2 began rising; sCD14 began increasing 6 months later. FABP2 and sCD14 peaked 6 and 6.5 years post-FMP, respectively; subsequent levels remained stable. During the ~9-year interval of MT-related gain in gut barrier compromise markers, annual FABP2 and sCD14 increases were 2.6% (95% CI: 1.7 to 3.4%) and 0.8% (95% CI: 0.6 to 1.1%), respectively, among white women with sample-average BMI and age at FMP.

However, the mechanisms underlying aging-related anemia, especially epigenetic dysregulation in hematopoietic stem and progenitor cells (HSPCs), remain incompletely understood. Although the gut microbiota is critical for hematopoiesis, its specific contribution to aging-related erythropoiesis impairment remains unclear. Here, we reveal that aging markedly activates phenylalanine metabolism and elevates plasma phenylacetic acid (PAA) levels in both humans and mice. We identify Odoribacter splanchnicus (O.splanchnicus) as a key gut symbiont whose abundance is significantly increased in aged mice and which directly drives PAA production from phenylalanine via the oxoacid:ferredoxin oxidoreductase (OFOR) superfamily encoded by porA,nifJ, and iorA/iorB. Rifaximin treatment selectively reduces O.splanchnicus and plasma PAA, thereby alleviating aging-related anemia. Mechanistically, PAA promotes a novel post-translational modification (PTMs) termed histone lysine phenylacetylation (Kpa) through the acetyltransferases HBO1. Elevated histone Kpa increases chromatin accessibility at the GATA2 promoter, disrupts the GATA switch, and blocks erythroid differentiation of HSPCs. In vivo, supplementation with sodium phenylacetate (NaPA) exacerbates anemia in microbiota-depleted mice, whereas the HBO1 inhibitor WM-3835 restores erythropoiesis by reversing histone Kpa and normalizing the GATA switch. Furthermore, dietary phenylalanine restriction lowers circulating PAA and effectively ameliorates aging-related anemia in both naturally aged mice and O.splanchnicus-colonized mice. These findings provide the first evidence that gut microbiota-derived PAA plays a critical role in the development of aging-related erythropoiesis impairment and offer multiple translatable strategies for treating this condition."},{"quadrant":"Run1_Eval1_synthesis","attempt":1,"quote":"These findings suggest that habitual cannabis use may protect gut barrier integrity and reduce microbial translocation and associated inflammation","status":"PASS","error":"","abstract_text":"ID: 42427618\nTitle: Preserved Barrier Integrity and Altered Immune Profiles in Chronic Cannabis Users: Potential Roles of Δ9-Tetrahydrocannabinol.\nAbstract: Although cannabinoids such as delta-9-tetrahydrocannabinol (THC) are generally immunosuppressive in preclinical models, chronic cannabis use in humans is paradoxically associated with increased infection risk and systemic inflammation. In this study, we demonstrate that THC directly strengthens intestinal epithelial barrier function in vitro by increasing trans-epithelial electrical resistance in a concentration-dependent manner in Caco-2 monolayers. In a cross-sectional study of chronic cannabis users via smoking or snorting compared with non-using controls, plasma lipopolysaccharide (LPS), and microbial translocation-driven inflammatory cytokines (IL-23, MCP-1, IL-8) were significantly reduced, while some cytokines (IL-6, IL-1β, TNF-α, IL-10) remained unchanged.

This study focuses on the regulatory effects of Muribaculaceae and β-muricholic acid (β-MA, a primary bile acid) on neurological injury after ICH, aiming to reveal the molecular mechanism by which it improves the prognosis of ICH through the sphingosine-1-phosphate receptor 2 (S1PR2). A mouse ICH model was constructed by collagenase induction to evaluate the changes in gut microbiota diversity and metabolites. After intervention with Muribaculum intestinale (MI), neurological function was assessed by behavioral tests, and pathological changes of brain tissue were analyzed by Hematoxylin-Eosin and Nissl staining. Subsequently, intestinal barrier function, inflammatory factors, and total bile acid (TBA) levels were examined in ICH mice. In addition, cell viability, apoptosis, oxidative stress, inflammatory factors, and β-MA levels were analyzed in the heme-induced SH-SY5Y cell model. Molecular docking and drug affinity responsiveness target stability (DARTS) were used to analyze the interaction between β-MA and S1PR2. Intervention with a S1PR2 agonist (CYM-5520) was used to further verify the mechanism. Altered gut microbiota composition, elevated lipopolysaccharide levels, reduced expression of tight junction proteins, inflammatory activation, and disrupted bile acid metabolism were observed in ICH mice.

Analyzing the piglets' intestinal microbiomes showed that different dietary treatments lead to variations in their bacterial communities. As a result, the lower dose increased the presence of probiotics and lactic acid bacteria, while the higher dose showed more bacterial taxa and a mixed microbial shift. Additionally, SL@Cur markedly reduced fecal NH₃ and H2S gas emissions (p < 0.05).

We investigated the therapeutic efficacy of the sialidase inhibitor (SI) in UC. In a pilot randomized clinical trial, SI intervention significantly improved clinical symptoms and endoscopic outcomes in mild-to-moderate UC patients. This improvement correlated with an enrichment of butyrate-producing taxa and beneficial metabolic pathways. In a dextran sulfate sodium-induced colitis mouse model, SI attenuated inflammation and restored mucus layer integrity, accompanied by increased expression of Muc2 and Tff3. Crucially, unlike broad-spectrum antibiotics, SI preserved microbial community resilience while specifically enriching beneficial mucolytic commensals, Akkermansia muciniphila and Bacteroides acidifaciens. These findings identify SI as a promising therapeutic strategy that targets sialidase activity to reinforce the mucosal barrier and restore gut homeostasis.IMPORTANCEThe gut microbiota plays a pivotal role in maintaining mucosal integrity and intestinal homeostasis; however, dysbiosis-driven mucus layer degradation remains a hallmark of ulcerative colitis (UC). Current interventions like antibiotics often disrupt microbial diversity, exacerbating dysbiosis and failing to address mucosal thinning, which is a critical factor in UC progression. Developing strategies to reinforce the mucus barrier without compromising microbial balance is urgently needed, but such approaches remain underexplored. Our study demonstrates that sialidase inhibitors (SIs) uniquely preserve mucosal thickness by curbing microbial mucin degradation while selectively enriching beneficial taxa and butyrate-producing bacteria. Unlike antibiotics, SIs enhance mucosal protection without destabilizing microbial communities, offering a dual-action therapeutic strategy. This work bridges a critical knowledge gap, providing evidence for microbiota-targeted therapies that synergistically restore mucosal health and microbial ecology in UC.CLINICAL TRIALSThis study was registered with the Chinese Clinial Trial Registry as ChiCTR2000028767."},{"quadrant":"Run1_Eval1_synthesis","attempt":1,"quote":"We propose that COPD is essentially a metabolically imprinted inflammatory memory disease, whose core mechanism resides in the chronic oxidative stress-triggered persistent remodeling of chromatin accessibility","status":"PASS","error":"","abstract_text":"ID: 42435486\nTitle: Metabolite-driven epigenetic modifications remodel immune cell functions in COPD: From Lactylation to Succinylation.\nAbstract: Chronic obstructive pulmonary disease (COPD) is characterized by persistent airway inflammation, progressive immune dysfunction, and irreversible structural remodeling. Although cigarette smoke-induced oxidative stress has long been recognized as the predominant pathogenic driver, conventional inflammatory theories fail to fully account for the sustained inflammatory state that persists even after smoking cessation. Accumulating evidence indicates that COPD is governed by a metabolite-centered epigenetic regulatory network. Intracellular metabolic intermediates function not only as substrates for energy metabolism, but also as signaling molecules that directly modulate chromatin architecture and transcriptional programs. In this context, metabolic reprogramming emerges as a pivotal determinant of immune cell fate and inflammatory memory formation. This review systematically summarizes recent research advances in the \"metabolite-redox-epigenetics\" axis in COPD. We specifically discuss histone lactylation as a glycolysis-dependent inflammatory amplification mechanism and propose that histone succinylation represents a redox-sensitive epigenetic mechanism linked to mitochondrial dysfunction, bridging tricarboxylic acid (TCA) cycle dysregulation and persistent immune activation. We further integrate acetylation, crotonylation, β-hydroxybutyrylation, DNA methylation, and RNA m6A modification to construct a unified immunometabolic regulatory network. We propose that COPD is essentially a metabolically imprinted inflammatory memory disease, whose core mechanism resides in the chronic oxidative stress-triggered persistent remodeling of chromatin accessibility, which stably enforces pathogenic immune phenotypes. Targeting metabolite-driven epigenetic remodeling may offer novel therapeutic strategies to reverse chronic inflammatory memory and restore immune homeostasis. Recent evidence further suggests that cGAS-STING-mediated mitochondrial DNA sensing, inflammasome-dependent pyroptosis, gut-lung axis-derived metabolites, and AMPK/SIRT1/PGC-1α signaling may provide additional links between metabolic stress, epithelial injury, and immune dysfunction."},{"quadrant":"Run1_Eval1_synthesis","attempt":1,"quote":"UroA treatment protected hAS3MT mice from iAs-induced gut permeability, inflammation, colon shortening, and elevated colon weight/length ratio.","status":"PASS","error":"","abstract_text":"ID: 42400257\nTitle: Microbial metabolite Urolithin A protects against inorganic arsenic-induced gut barrier dysfunction in humanized AS3MT mice.\nAbstract: Chronic exposure to inorganic arsenic (iAs) remains a major environmental health concern and is associated with significant gastrointestinal (GI) disorders, including gastroenteritis, diarrhea, and inflammatory bowel disease-like symptoms. Gut microbiota plays a critical role in mitigating arsenic toxicity, as germ-free or antibiotic-treated mice exhibit reduced fecal arsenic excretion and greater tissue accumulation. We previously showed that the microbial metabolite Urolithin A (UroA) protects against iAs-induced cytotoxicity, apoptosis, oxidative stress, and ROS production in vitro.

Long-term iAs exposure (100 ppb for 28 weeks) significantly reduced expression of tight junction proteins, indicating compromised intestinal barrier integrity. UroA treatment protected hAS3MT mice from iAs-induced gut permeability, inflammation, colon shortening, and elevated colon weight/length ratio. UroA also reduced iAs-induced inflammatory cytokines, myeloperoxidase (MPO) activity and preserved intestinal epithelial cell tight junction protein expression.

Emerging evidence shows that beneficial microbial taxa, including Akkermansia muciniphila, Bifidobacterium longum, and Parabacteroides distasonis, enhance liver regeneration by regulating short-chain fatty acid production, bile acid metabolism, and tricarboxylic acid cycle pathways, while dysbiosis and microbial translocation can impair regenerative outcomes.

Here, the fish were randomly assigned to five groups: a control group (CON), a high-fat high-carbohydrate diet (HFHC) group, a HFHC + 300 mg/kg chenodeoxycholic acid (CDCA) group, a HFHC + 300 mg/kg ursodeoxycholic acid (UDCA) group and a HFHC + 300 mg/kg hyodeoxycholic acid (HDCA) group. The results revealed that the serum triglyceride, glucose, and total cholesterol levels were significantly elevated in HFHC-fed fish, accompanied by increased glutamic-oxaloacetic transaminase (GOT) and glutamic-pyruvic transaminase (GPT) activities in the serum and hepatopancreas. However, dietary supplementation with bile acids in the HFHC diet significantly improved these negative changes. Analysis of BA-glycolipid metabolism-related gene expression and enzyme activities in the hepatopancreas revealed that CDCA and HDCA inhibited gluconeogenesis (FBPase/PEPCK/G6Pase) and lipogenesis (SREBP-1/FAS), while promoting glycogen accumulation (genes and glycogen levels) and fatty acid β-oxidation (PPARα) via activation of the FXR (farnesoid X receptor) /SHP (small heterodimer partner) pathway. In contrast, dietary UDCA supplementation increased intestinal TGR5 (takeda G protein-coupled receptor 5) expression and suppressed the activities of two key gluconeogenic enzymes, PEPCK and G6Pase. Additionally, dietary BAs supplementation alleviated HFHC diet-induced intestinal inflammation by inhibiting the NF-κB (Nuclear Factor κB) pathway. Bile acids relieved gut dysbiosis, improved microbial alpha diversity and community structure, and enriched beneficial bacteria including Cetobacterium somerae. These microbial changes eventually modulated host substance synthesis and metabolism. HE staining showed that HFHC diet caused hepatopancreatic lesions and intestinal morphological damage in Yellow River carp, which were effectively alleviated by bile acid addition.

Cardiac function was assessed by echocardiography and pressure-volume catheterization. Ferroptosis biomarkers were quantified.

In this review, we explore recent progress in understanding the gut microbiota's role in liver regeneration and discuss its therapeutic potential in the context of hepatic surgery and liver transplantation. Emerging evidence shows that beneficial microbial taxa, including Akkermansia muciniphila, Bifidobacterium longum, and Parabacteroides distasonis, enhance liver regeneration by regulating short-chain fatty acid production, bile acid metabolism, and tricarboxylic acid cycle pathways, while dysbiosis and microbial translocation can impair regenerative outcomes. Key host-microbiome interactions, particularly the Farnesoid X Receptor (FXR)-Fibroblast Growth Factor 19 (FGF19) signaling axis, play a central role in protecting hepatocytes from bile acid overload and supporting regeneration, highlighting the therapeutic potential of FXR agonists, FGF19 mimetics, probiotics, dietary interventions, and metabolite supplementation.

Although this review uses the MASLD-MASH-fibrosis/cirrhosis-HCC sequence as a mechanistically informative model, the gut-liver-immune framework is also relevant, with important etiology-specific differences, to alcohol-associated liver disease (ALD), chronic hepatitis B virus (HBV) infection, chronic hepatitis C virus (HCV) infection, and mixed-etiology liver disease. Across these contexts, hepatocyte lipotoxicity or viral/alcohol-induced injury, mitochondrial stress, endotoxemia, altered bile-acid signaling, fibrotic remodeling, and immune exhaustion progressively reshape the hepatic microenvironment toward tumor-permissive inflammation and immune escape. We integrate transcriptomic, single-cell, spatial, microbial, and metabolomic evidence to define stage- and etiology-dependent immunometabolic states.

Gut microbiota plays a critical role in mitigating arsenic toxicity, as germ-free or antibiotic-treated mice exhibit reduced fecal arsenic excretion and greater tissue accumulation. We previously showed that the microbial metabolite Urolithin A (UroA) protects against iAs-induced cytotoxicity, apoptosis, oxidative stress, and ROS production in vitro. In this study, using humanized AS3MT mice (mouse arsenic methyltransferase gene (As3mt)replaced with human AS3MT, hAS3MT), we evaluated the in vivo effects of iAs and UroA on gut barrier function. Long-term iAs exposure (100 ppb for 28 weeks) significantly reduced expression of tight junction proteins, indicating compromised intestinal barrier integrity. UroA treatment protected hAS3MT mice from iAs-induced gut permeability, inflammation, colon shortening, and elevated colon weight/length ratio. UroA also reduced iAs-induced inflammatory cytokines, myeloperoxidase (MPO) activity and preserved intestinal epithelial cell tight junction protein expression. Further, microbiome and metabolomic analysis suggested that UroA treatment protected from iAs-induced gut microbial dysbiosis, especially restored several beneficial bacterial strains and short chain fatty acids (e.g., acetate and butyrate) and led to gut homeostasis.

This result was further proved by significant changes in lipogenesis and lipolysis-related protein expressions in adipocyte. Administration of GRE also suppressed development of MASLD, which was observed through reductions in serum ALT and AST and suppressions the expression of FAS, SREBP1, mTOR, SCD1, ACC, and ChREBP in liver tissues.

Although cigarette smoke-induced oxidative stress has long been recognized as the predominant pathogenic driver, conventional inflammatory theories fail to fully account for the sustained inflammatory state that persists even after smoking cessation. Accumulating evidence indicates that COPD is governed by a metabolite-centered epigenetic regulatory network. Intracellular metabolic intermediates function not only as substrates for energy metabolism, but also as signaling molecules that directly modulate chromatin architecture and transcriptional programs. In this context, metabolic reprogramming emerges as a pivotal determinant of immune cell fate and inflammatory memory formation. This review systematically summarizes recent research advances in the \"metabolite-redox-epigenetics\" axis in COPD. We specifically discuss histone lactylation as a glycolysis-dependent inflammatory amplification mechanism and propose that histone succinylation represents a redox-sensitive epigenetic mechanism linked to mitochondrial dysfunction, bridging tricarboxylic acid (TCA) cycle dysregulation and persistent immune activation. We further integrate acetylation, crotonylation, β-hydroxybutyrylation, DNA methylation, and RNA m6A modification to construct a unified immunometabolic regulatory network. We propose that COPD is essentially a metabolically imprinted inflammatory memory disease, whose core mechanism resides in the chronic oxidative stress-triggered persistent remodeling of chromatin accessibility, which stably enforces pathogenic immune phenotypes. Targeting metabolite-driven epigenetic remodeling may offer novel therapeutic strategies to reverse chronic inflammatory memory and restore immune homeostasis.

However, the mechanisms underlying aging-related anemia, especially epigenetic dysregulation in hematopoietic stem and progenitor cells (HSPCs), remain incompletely understood. Although the gut microbiota is critical for hematopoiesis, its specific contribution to aging-related erythropoiesis impairment remains unclear. Here, we reveal that aging markedly activates phenylalanine metabolism and elevates plasma phenylacetic acid (PAA) levels in both humans and mice. We identify Odoribacter splanchnicus (O.splanchnicus) as a key gut symbiont whose abundance is significantly increased in aged mice and which directly drives PAA production from phenylalanine via the oxoacid:ferredoxin oxidoreductase (OFOR) superfamily encoded by porA,nifJ, and iorA/iorB. Rifaximin treatment selectively reduces O.splanchnicus and plasma PAA, thereby alleviating aging-related anemia.

Elevated histone Kpa increases chromatin accessibility at the GATA2 promoter, disrupts the GATA switch, and blocks erythroid differentiation of HSPCs. In vivo, supplementation with sodium phenylacetate (NaPA) exacerbates anemia in microbiota-depleted mice, whereas the HBO1 inhibitor WM-3835 restores erythropoiesis by reversing histone Kpa and normalizing the GATA switch. Furthermore, dietary phenylalanine restriction lowers circulating PAA and effectively ameliorates aging-related anemia in both naturally aged mice and O.splanchnicus-colonized mice. These findings provide the first evidence that gut microbiota-derived PAA plays a critical role in the development of aging-related erythropoiesis impairment and offer multiple translatable strategies for treating this condition."},{"quadrant":"Run1_Eval1_synthesis","attempt":2,"quote":"Supplementation with MI ameliorated neural damage, cerebral edema, and neuronal loss in an intake dose-responsive manner, enhanced intestinal barrier integrity","status":"PASS","error":"","abstract_text":"ID: 42435878\nTitle: Muribaculaceae regulate β-muricholic acid to target S1PR2 signaling and reduce neurological injury in intracerebral hemorrhage.\nAbstract: Intestinal flora imbalance after intracerebral hemorrhage (ICH) aggravates neuroinflammation and secondary brain injury through the gut-brain axis, although the specific mechanism remains unclear. This study focuses on the regulatory effects of Muribaculaceae and β-muricholic acid (β-MA, a primary bile acid) on neurological injury after ICH, aiming to reveal the molecular mechanism by which it improves the prognosis of ICH through the sphingosine-1-phosphate receptor 2 (S1PR2). A mouse ICH model was constructed by collagenase induction to evaluate the changes in gut microbiota diversity and metabolites. After intervention with Muribaculum intestinale (MI), neurological function was assessed by behavioral tests, and pathological changes of brain tissue were analyzed by Hematoxylin-Eosin and Nissl staining. Subsequently, intestinal barrier function, inflammatory factors, and total bile acid (TBA) levels were examined in ICH mice. In addition, cell viability, apoptosis, oxidative stress, inflammatory factors, and β-MA levels were analyzed in the heme-induced SH-SY5Y cell model. Molecular docking and drug affinity responsiveness target stability (DARTS) were used to analyze the interaction between β-MA and S1PR2. Intervention with a S1PR2 agonist (CYM-5520) was used to further verify the mechanism. Altered gut microbiota composition, elevated lipopolysaccharide levels, reduced expression of tight junction proteins, inflammatory activation, and disrupted bile acid metabolism were observed in ICH mice. Supplementation with MI ameliorated neural damage, cerebral edema, and neuronal loss in an intake dose-responsive manner, enhanced intestinal barrier integrity, and increased TBA levels. As a primary bile acid, β-MA directly mitigated hemin-induced oxidative stress and inflammation in neural cells. Mechanistically, β-MA downregulated the expression of S1PR2, but overexpression of S1PR2 counteracted the protective effects of β-MA. Furthermore, the administration of CYM-5520 attenuated the neuroprotective effects conferred by MI in vivo. Muribaculaceae alleviated neurological injury after ICH by upregulating β-MA levels, thereby inhibiting the S1PR2 signaling pathway. This research offers a novel approach to treating ICH by focusing on the gut microbiota-bile acid metabolism-neuroprotection axis."},{"quadrant":"Run1_Eval1_synthesis","attempt":2,"quote":"These findings suggest that habitual cannabis use may protect gut barrier integrity and reduce microbial translocation and associated inflammation","status":"PASS","error":"","abstract_text":"ID: 42427618\nTitle: Preserved Barrier Integrity and Altered Immune Profiles in Chronic Cannabis Users: Potential Roles of Δ9-Tetrahydrocannabinol.\nAbstract: Although cannabinoids such as delta-9-tetrahydrocannabinol (THC) are generally immunosuppressive in preclinical models, chronic cannabis use in humans is paradoxically associated with increased infection risk and systemic inflammation. In this study, we demonstrate that THC directly strengthens intestinal epithelial barrier function in vitro by increasing trans-epithelial electrical resistance in a concentration-dependent manner in Caco-2 monolayers. In a cross-sectional study of chronic cannabis users via smoking or snorting compared with non-using controls, plasma lipopolysaccharide (LPS), and microbial translocation-driven inflammatory cytokines (IL-23, MCP-1, IL-8) were significantly reduced, while some cytokines (IL-6, IL-1β, TNF-α, IL-10) remained unchanged.

Analyzing the piglets' intestinal microbiomes showed that different dietary treatments lead to variations in their bacterial communities. As a result, the lower dose increased the presence of probiotics and lactic acid bacteria, while the higher dose showed more bacterial taxa and a mixed microbial shift. Additionally, SL@Cur markedly reduced fecal NH₃ and H2S gas emissions (p < 0.05).

Herbal medicines offer multi-component therapeutic potential through microbiota modulation, but mechanistic insights remain fragmented. This review synthesizes recent advances in herbal medicine-mediated gut microbiota regulation in metabolic diseases and delineates underlying molecular mechanisms. A comprehensive literature search was conducted across PubMed and Web of Science. Search strategies employed MeSH terms and free-text keywords encompassing herbal medicines, gut microbiota, and metabolic diseases. Two authors performed study selection and data extraction. Evidence synthesis was structured according to intervention type and metabolic disease category. Herbal polysaccharides and other compounds consistently increased beneficial bacteria and promoted short-chain fatty acids (SCFAs) production, improving intestinal barrier integrity via ZO-1/Occludin upregulation and attenuating TLR4/NF-κB-mediated inflammation. Herbal formulations exerted synergistic effects by remodeling microbial community structure, correcting SCFA/bile acid imbalances, and activating IRS1/PI3K/AKT insulin signaling. Notably, Lactobacillus and Akkermansia emerged as recurrent beneficial targets across multiple herbal interventions. However, evidence is predominantly preclinical, and translational validity to humans requires further validation.

The latest research shows that its pathogenesis is closely related to the imbalance of gut microbiota. Prunella vulgaris L. is an edible-medicinal plant containing bioactive compounds such as polyphenols that can lower cholesterol and protect the liver. However, whether it has anti MASLD effects has not been reported. The present study aimed to investigate the effect of Prunella vulgaris polyphenols (PVP) on alleviating MASLD from the perspective of the gut-liver axis. PVP composition was characterized via UPLC-MS/MS and HPLC. Enzymatic kinetics, fluorescence quenching, and molecular docking were used to study the inhibition of PVP and rosmarinic acid (RA) on cholesterol esterase (CEase). Effects on liver lipid accumulation and intestinal cholesterol transport were assessed using HepG2 and Caco-2 cell models. A MASLD mouse model was evaluated through ELISA, tissue staining, and 16S rRNA sequencing to determine the efficacy and mechanisms. PVP and RA exhibited anti-competitive inhibition of CEase, with IC50 values of 1.63 ± 0.06 and 0.39 ± 0.17 mg/mL, respectively. RA showed strong binding to CEase. PVP and RA significantly alleviated hepatic lipid accumulation in HepG2 cells, inhibited intestinal cholesterol absorption, and promoted cholesterol efflux in Caco-2 monolayers. In MASLD mice, PVP significantly reduced serum ALT, TBA, and TG, lowered hepatic TC and fecal TBA (P < 0.05), and ameliorated liver pathological damage. In addition, both PVP and RA modified the composition of gut microbiota in the cecum, which characterized by a reduction in bile acid (BA)-related bacteria such as g_UBA7173, g_Bacteroides_H, f_Burkholderiaceae_A, g_Phocaeicola_A, and g_Turicimonas, while increasing f_Lachnospiraceae and f_Oscillospiraceae.

Herein, we demonstrate that maternal cold exposure in early pregnancy markedly improved offspring glucose tolerance, insulin sensitivity, and hepatic lipid metabolism when challenged with a Western diet, and the benefits persisted into late adulthood. Transcriptomic and immunophenotyping analyses revealed that offspring with cold-exposed dams exhibited suppressed Th17 activity and IL-17 signaling.

LCA supplementation recapitulates these benefits through gut microbiota-dependent conversion to 3-oxo-LCA. Furthermore, Clostridium scindens supplementation enhanced 3-oxo-LCA production, suppressed Th17 responses, and alleviated diet-induced hepatic steatosis.

By inhibiting the gastric H⁺/K⁺-ATPase, PPIs suppress acid secretion and impair bacterial killing, thereby promoting gut dysbiosis that disrupts barrier integrity and enhances bacterial translocation, ultimately exacerbating liver injury. PPIs are frequently co-administered with antibiotics for indications such as gastrointestinal bleeding, Spontaneous Bacterial Peritonitis (SBP), other infections, or hepatic encephalopathy prophylaxis, but the consequences of this combined therapy on gut microbial ecology and disease outcomes remain unclear. Our study addresses this gap by showing how PPI use, alone or with antibiotics, reshapes the gut microbiome and aggravates liver disease progression. In previous studies, we showed that PPIs promote dysbiosis and ALD progression in mice and humans by facilitating intestinal expansion and hepatic translocation of Gram-positive Enterococcus. Fecal cytolysin, an Enterococcus faecalis exotoxin that induces hepatocyte death, predicts mortality in patients with alcohol-associated hepatitis (AH). In this study, we have examined the mechanism by which PPIs alone and in combination with non-absorbable antibiotics targeting Gram-positive bacteria influence ALD, as well as the disease mechanisms associated with cytolytic Enterococcus faecalis and the development of therapeutic strategies. In mice, alcohol administration during gastric acid suppression promoted expansion of Gram-positive taxa, including cytolysin-producing Enterococcus. Similarly, PPI use in patients with AH was associated with increased fecal Enterococcus and higher 30-d mortality, underscoring the translational relevance of our findings. Unexpectedly, treatment of acid-suppressed mice with non-absorbable antibiotics designed to suppress Gram-positive bacteria worsened ethanol-induced steatohepatitis: while Enterococcus abundance decreased, Streptococcus and other potentially pathogenic taxa expanded, leading to increased bacterial translocation and aggravated liver injury. In patients with cirrhosis or metabolic dysfunction-associated steatotic liver disease (MASLD), PPIs did not promote Enterococcus expansion, indicating etiology-dependent microbiome responses. Finally, we identified dipalmitoylphosphatidylcholine and Caspase-1 inhibitor as in vitro and in vivo modulators of cytolysin activity, highlighting potential therapeutic avenues. Collectively, our study demonstrates how PPIs and non-absorbable antibiotics targeting Gram-positive bacteria interact with the gut microbiome to drive ALD, underscoring the need for careful therapeutic management."},{"quadrant":"Run2_Eval1_synthesis","attempt":1,"quote":"cis-Gnetin H remodeled the gut microbiota by enriching beneficial genera and reducing pathogenic Staphylococcus.","status":"PASS","error":"","abstract_text":"ID: 42419122\nTitle: Discovery of cis-Gnetin H from peony seed coat as a potent antifibrotic agent modulating hepatic fibro-inflammatory pathways and gut microbiota homeostasis.\nAbstract: Liver fibrosis is a reversible stage of chronic liver disease lacking effective therapies. The peony seed coat, a major byproduct of peony oil production, is rich in bioactive stilbenes. However, its anti-fibrotic potential and underlying mechanisms remain systematically unexplored. This study aimed to isolate stilbenes from peony seed coat, identify the potent anti-fibrotic compounds, and evaluate their anti-fibrotic activity and mechanisms of action. A structure-oriented separation strategy, guided by spectroscopic analysis, enabled the isolation of stilbenes. Anti-fibrotic activity was screened in TGF-β1-induced hepatic stellate cells (HSCs). In vivo efficacy was evaluated in a CCl₄-induced mouse liver fibrosis model. Mechanisms were investigated using transcriptomics, Western blotting, and 16S rRNA gene sequencing.

In this multicenter randomized trial, participants (50% women) were assigned to UC (n=49), early TRE (n=49), late TRE (n=52), or self-selected TRE (n=47). Hepatic fat fraction was assessed by MRI; liver markers included elastography-based parameters, liver enzymes, and circulating biomarkers. Fecal microbiota was analyzed by 16S rRNA gene sequencing. Hepatic fat fraction decreased significantly within the three TRE groups (all P≤0.02), but no between-group differences were observed when comparing early TRE (mean difference [MD]: -0.4%; P=0.95), late TRE (MD: -1.5%; P=0.15), and self-selected TRE groups (MD: -0.7%; P=0.77) with the UC group, or among the TRE groups themselves (all P≥0.41).

Participants with metabolic dysfunction-associated steatotic liver disease at baseline as well as those achieving ≥5% weight loss had greater reductions in hepatic fat fraction than those who did not (MD: -2.7 and -2.6%; respectively, both P<0.001). A higher proportion of participants in the TRE groups achieved ≥5% weight loss compared with UC (41-44% vs 16%; P=0.001).

In this 12-week multicenter randomized trial, adding early, late, or self-selected 8-hour TRE to Mediterranean diet-based usual care led to within-group reductions in MRI-assessed hepatic fat fraction, but did not confer greater improvements in hepatic fat fraction, liver health markers, or fecal microbiota than usual care alone. Participants with baseline metabolic dysfunction-associated steatotic liver disease (MASLD) and those achieving ≥5% weight loss experienced larger reductions in hepatic fat fraction, suggesting these reductions in this context are more closely linked to weight loss and baseline steatosis than to eating-window timing. Clinically, these findings support prioritizing feasible eating schedules and strategies that help patients attain clinically meaningful weight loss, particularly among individuals with MASLD."},{"quadrant":"Run2_Eval1_synthesis","attempt":1,"quote":"Sinensetin administration ameliorated hepatic steatosis, inflammation, and restored intestinal integrity in HFD-fed mice.","status":"PASS","error":"","abstract_text":"ID: 42421922\nTitle: Sinensetin ameliorates established high-fat diet-induced liver injury and intestinal barrier dysfunction through the mitophagy/TLR4/MAPK signaling pathway.\nAbstract: Long-term consumption of a high-fat diet (HFD) causes liver injury characterized by steatosis, inflammation, and fibrosis.

Ceramidases and ceramides are associated with MASH, yet the role of intestinal neutral ceramidase in MASH development remains unclear. Murine models with intestinal epithelial cell (IEC)-specific depletion of neutral ceramidase (Asah2ΔIEC ) or aryl hydrocarbon receptor (AhR ΔIEC) were subjected to either a Western diet (WD) at 6 weeks old for 10-12 months to induce MASH, or a hydrogenated vegetable oil, sucrose, palmitate and cholesterol (HSPC) diet to accelerate MASH progression. Fecal microbiota transplantation was performed in germ-free mice. MASH is associated with the induction of neutral ceramidase, which reshapes the intestinal microbiota and metabolite profiles, leading to increased production of 2-hydroxyhippuric acid (2-HHA). We identified 2-HHA as an inhibitor of AhR signalling, a pathway that normally promotes intestinal fucosylation. Elevated 2-HHA suppresses AhR activity, reduces fucosylation and contributes to MASH and associated airway inflammation in mice fed WD or HSPC diet. Notably, IEC-specific deletion of neutral ceramidase decreases 2-HHA levels, restores AhR signalling, enhances fucosylation and protects against MASH.

DYMJ treatment restored microbial balance closer to normal-diet (ND) conditions, particularly by elevating nicotinic acid adenine dinucleotide and enriching Bacteroidetes phylum species associated with metabolic health. These findings suggested that DYMJ mitigated obesity through dual mechanisms: alleviating oxidative stress and hepatic lipid accumulation, while reshaping gut microbiota toward a metabolic health-promoting composition.

The study evaluated RGE's effects on hyperlipidemia and gut microbiota through serum biochemical analysis, hepatic histopathology, cecal metabolomics, 16S rRNA sequencing, and further investigated hepatic regulatory mechanisms using molecular biology techniques. After 60 days of treatment, RGE significantly reduced serum lipid levels and liver injury markers.

LC-MS and 16S rRNA sequencing of cecal contents revealed that RGE remodeled gut microbiota composition, enhancing microbiota-derived metabolite production. Molecular analysis indicated that RGE activated hepatic PPARα, downregulated SREBP-1c, and partially restored basal cholesterol biosynthesis by upregulating HMGCR mRNA. These changes collectively reduced hepatic triglyceride accumulation and promoted cholesterol excretion. RGE alleviates HFD-induced hyperlipidemia and hepatic steatosis through a coordinated gut-liver axis mechanism, involving microbiota modulation, metabolic reprogramming, and regulation of hepatic lipid factors.

Whether inflammatory signals triggered by HFD-induced gut dysbiosis are transmitted to the placenta via the maternal-fetal axis warrant further investigation. This study aims to elucidate the mechanistic connection between maternal gut dysbiosis and placental inflammation, thereby offering insights into microbiota-mediated developmental origins of metabolic diseases in offspring. Female C57BL/6 mice were exposed to high fat diet (HFD) for 5 weeks prior to mating with male mice. Gut microbiota was profiled by using 16 S rRNA sequencing and fecal short-chain fatty acids (SCFAs) were quantified by GC-MS from HFD pregnant mice at gestational day 18.5 (G18.5). Mice were sacrificed at G18.5, and placenta histopathological analysis as well as inflammatory markers and lipopolysaccharide (LPS) level were analyzed. Anti-inflammatory effects of butyrate were evaluated in vitro by using HTR-8/Svneo cells and in vivo through gestational supplementation (0.3 mg/g body weight) in HFD-fed dams. Maternal HFD exposure induced significant placental inflammation as well as hepatic steatosis in the offspring. HFD-fed dams exhibited distinct gut dysbiosis with reduced fecal and serum SCFAs, which was accompanied by elevated placental LPS levels and exacerbated inflammatory responses. Butyrate treatment suppressed the expression of inflammatory cytokines in vitro through down-regulating the phosphorylation of NF-κB, ERK1/2 signaling pathways via G-protein-coupled receptor 41 (GPR41). Furthermore, gestational butyrate intervention effectively alleviated placental inflammation and mitigated fetal hepatic lipid deposition in HFD-exposed offspring. Placental inflammation caused by maternal HFD is closely associated with gut microbiota dysbiosis.

This study investigated the effects of walnut green husk polyphenol extracts (WGHPE) on fatty liver hemorrhagic syndrome (FLHS)-related indicators, antioxidant performance, and cecal microbiota modulation in laying hens. A total of 350 Hy-Line Brown laying hens aged 43 weeks were randomly assigned to five groups with seven replicates per group and 10 hens per replicate. An FLHS model was induced via intramuscular injection of β-estradiol dissolved in corn oil. The control (Con) and FLHS model groups received a basal diet, whereas three FLHS-based treatment groups were fed the basal diet supplemented with 0.5% (WGHPEL), 1.0% (WGHPEM), or 1.5% (WGHPEH) WGHPE, respectively. All laying hens had unrestricted access to food and water throughout the 8-week experimental period. Compared with the FLHS group, dietary supplementation with WGHPE significantly reduced liver weight, liver coefficient, abdominal adipose weight, and abdominal adipose coefficient. Histological evaluation demonstrated that WGHPE alleviated hepatocellular vacuolar degeneration and lipid droplet accumulation, indicating an improvement in FLHS-related pathological features. Furthermore, WGHPE significantly reversed FLHS-induced elevations in serum levels of total cholesterol, aspartate aminotransferase, alanine aminotransferase, and low-density lipoprotein cholesterol. WGHPE also enhanced systemic antioxidant capacity by increasing catalase and total superoxide dismutase activities in β-estradiol/corn oil-induced laying hens, while decreasing malondialdehyde levels. Regarding intestinal health, WGHPE significantly increased villus height and the villus-to-crypt ratio in the jejunum and ileum. Furthermore, in the WGHPE treatment group, the relative abundance of beneficial bacterial taxa was increased. Campylobacter and Parasutterella were positively correlated with body weight and abdominal adipose deposition, whereas Desulfovibrio and unclassified_Oscillospiraceae showed negative correlations. These findings collectively indicate beneficial associations between dietary WGHPE supplementation, intestinal microbiota composition, and overall health status in laying hens with FLHS. Dietary supplementation with WGHPE mitigated β-estradiol/corn oil-induced FLHS-associated liver injury, enhanced antioxidant capacity, and improved intestinal morphology and microbial composition.

This study aimed to clarify the pathogenic effects of E. faecalis in acute alcohol-associated liver disease (ALD) and to assess the protective potential of Akkermansia muciniphila (Akk11) against this pathogen. Using a mouse model of acute ethanol gavage, animals received E. faecalis and/or Akk11 under prophylactic or therapeutic regimens. Assessments included liver injury markers, histopathology, lipid profiles, inflammatory cytokines, gut barrier integrity, and gut microbiota composition. E. faecalis exacerbated ethanol-induced hepatic steatosis and injury, showing a paradoxical effect: it increased histological damage while lowering circulating LPS and transaminases. This was linked to upregulated hepatic autophagy (increased Atg7) and reduced cholesterol, yet it promoted neutral lipid accumulation. Importantly, E. faecalis aggravated gut dysbiosis by markedly enriching the pro-inflammatory pathobiont Helicobacter typhlonius and impairing colonic barrier function. Intervention with Akk11 alleviated liver injury, reduced lipid accumulation and oxidative stress, and restored cytokine balance. Akk11 also strengthened gut barrier integrity, lowered serum endotoxin, and beneficially reshaped the microbiota. Prophylactic administration was particularly effective, normalizing the Firmicutes/Bacteroidota ratio, suppressing H. typhlonius, and enriching beneficial Bacteroides sartorii.

Conventional polypharmacy often presents long-term compliance issues and side effects. Eucommia ulmoides Oliv., a traditional medicinal and edible plant rich in iridoids, lignans, flavonoids, and polysaccharides, has emerged as a promising natural intervention. This review aims to systematically summarize the bioavailability and multifaceted pharmacological mechanisms of E. ulmoides and its bioactive components in alleviating MetS. Methods: We comprehensively reviewed the recent in vitro and in vivo literature to map the functional evidence, specific signaling pathways, and gut microbiota-host interactions associated with E. ulmoides extracts and its key phytochemicals (e.g., asperuloside) against various metabolic dysfunctions. Results: Current evidence indicates that E. ulmoides operates through a \"multi-component, multi-target, and multi-pathway\" paradigm. For hyperlipidemia and obesity, it activates hepatic lipid metabolism (PPARα/CPT1A, FXR/CYP7A1) and mitigates oxidative stress (Nrf2/ARE). Furthermore, it dose-dependently reshapes the gut microbiota by enriching beneficial bacteria like Akkermansia and increasing butyrate production, exerting profound gut-liver axis regulation. It also ameliorates hypertension by activating the ACE2-Ang-(1-7)-Mas axis, improves insulin resistance via the AMPK/PI3K/Akt cascade, and manages hyperuricemia by modulating XOD and renal transporters. Notably, the low oral bioavailability of its glycosides highlights the crucial role of gut microbial hydrolysis in its efficacy. Conclusions: E. ulmoides holds substantial therapeutic potential as a multi-target natural supplement for MetS. However, future translational applications necessitate large-scale randomized clinical trials, multi-omics studies to further clarify host-microbiome interactions, and the development of standardized formulations to ensure clinical efficacy."},{"quadrant":"Run2_Eval1_synthesis","attempt":1,"quote":"Because oral and gut microbiota are strongly involved in MASLD in older individuals, improving oral hygiene and probiotics may prevent the onset and progression of MASLD","status":"PASS","error":"","abstract_text":"ID: 42318107\nTitle: Effect of Oral and Gut Microbiota, Dietary Intake, and Genetic Polymorphisms on Older Adults with Metabolic Dysfunction Associated Fatty Liver Disease.\nAbstract: This study aimed to investigate the factors involved in the development and progression of metabolic dysfunction-associated fatty liver disease (MASLD) in older adults from various aspects.

The latest research shows that its pathogenesis is closely related to the imbalance of gut microbiota. Prunella vulgaris L. is an edible-medicinal plant containing bioactive compounds such as polyphenols that can lower cholesterol and protect the liver. However, whether it has anti MASLD effects has not been reported. The present study aimed to investigate the effect of Prunella vulgaris polyphenols (PVP) on alleviating MASLD from the perspective of the gut-liver axis. PVP composition was characterized via UPLC-MS/MS and HPLC. Enzymatic kinetics, fluorescence quenching, and molecular docking were used to study the inhibition of PVP and rosmarinic acid (RA) on cholesterol esterase (CEase). Effects on liver lipid accumulation and intestinal cholesterol transport were assessed using HepG2 and Caco-2 cell models. A MASLD mouse model was evaluated through ELISA, tissue staining, and 16S rRNA sequencing to determine the efficacy and mechanisms. PVP and RA exhibited anti-competitive inhibition of CEase, with IC50 values of 1.63 ± 0.06 and 0.39 ± 0.17 mg/mL, respectively. RA showed strong binding to CEase. PVP and RA significantly alleviated hepatic lipid accumulation in HepG2 cells, inhibited intestinal cholesterol absorption, and promoted cholesterol efflux in Caco-2 monolayers.

By inhibiting the gastric H⁺/K⁺-ATPase, PPIs suppress acid secretion and impair bacterial killing, thereby promoting gut dysbiosis that disrupts barrier integrity and enhances bacterial translocation, ultimately exacerbating liver injury. PPIs are frequently co-administered with antibiotics for indications such as gastrointestinal bleeding, Spontaneous Bacterial Peritonitis (SBP), other infections, or hepatic encephalopathy prophylaxis, but the consequences of this combined therapy on gut microbial ecology and disease outcomes remain unclear. Our study addresses this gap by showing how PPI use, alone or with antibiotics, reshapes the gut microbiome and aggravates liver disease progression. In previous studies, we showed that PPIs promote dysbiosis and ALD progression in mice and humans by facilitating intestinal expansion and hepatic translocation of Gram-positive Enterococcus. Fecal cytolysin, an Enterococcus faecalis exotoxin that induces hepatocyte death, predicts mortality in patients with alcohol-associated hepatitis (AH). In this study, we have examined the mechanism by which PPIs alone and in combination with non-absorbable antibiotics targeting Gram-positive bacteria influence ALD, as well as the disease mechanisms associated with cytolytic Enterococcus faecalis and the development of therapeutic strategies. In mice, alcohol administration during gastric acid suppression promoted expansion of Gram-positive taxa, including cytolysin-producing Enterococcus. Similarly, PPI use in patients with AH was associated with increased fecal Enterococcus and higher 30-d mortality, underscoring the translational relevance of our findings. Unexpectedly, treatment of acid-suppressed mice with non-absorbable antibiotics designed to suppress Gram-positive bacteria worsened ethanol-induced steatohepatitis: while Enterococcus abundance decreased, Streptococcus and other potentially pathogenic taxa expanded, leading to increased bacterial translocation and aggravated liver injury. In patients with cirrhosis or metabolic dysfunction-associated steatotic liver disease (MASLD), PPIs did not promote Enterococcus expansion, indicating etiology-dependent microbiome responses. Finally, we identified dipalmitoylphosphatidylcholine and Caspase-1 inhibitor as in vitro and in vivo modulators of cytolysin activity, highlighting potential therapeutic avenues. Collectively, our study demonstrates how PPIs and non-absorbable antibiotics targeting Gram-positive bacteria interact with the gut microbiome to drive ALD, underscoring the need for careful therapeutic management."},{"quadrant":"Run2_Eval1_synthesis","attempt":2,"quote":"cis-Gnetin H remodeled the gut microbiota by enriching beneficial genera and reducing pathogenic Staphylococcus.","status":"PASS","error":"","abstract_text":"ID: 42419122\nTitle: Discovery of cis-Gnetin H from peony seed coat as a potent antifibrotic agent modulating hepatic fibro-inflammatory pathways and gut microbiota homeostasis.\nAbstract: Liver fibrosis is a reversible stage of chronic liver disease lacking effective therapies.

Hepatic fat fraction decreased significantly within the three TRE groups (all P≤0.02), but no between-group differences were observed when comparing early TRE (mean difference [MD]: -0.4%; P=0.95), late TRE (MD: -1.5%; P=0.15), and self-selected TRE groups (MD: -0.7%; P=0.77) with the UC group, or among the TRE groups themselves (all P≥0.41). Similarly, no between-group differences were found in liver health markers and fecal microbiota. Participants with metabolic dysfunction-associated steatotic liver disease at baseline as well as those achieving ≥5% weight loss had greater reductions in hepatic fat fraction than those who did not (MD: -2.7 and -2.6%; respectively, both P<0.001). A higher proportion of participants in the TRE groups achieved ≥5% weight loss compared with UC (41-44% vs 16%; P=0.001). These findings suggest that the timing of the eating window in TRE may not impact hepatic fat fraction or microbiota composition beyond the effects of weight loss, though the study was not powered for secondary outcomes. The study was registered on ClinicalTrials.gov (identifier: NCT05310721). NCT05310721 IMPACT AND IMPLICATIONS: Time-restricted eating (TRE) is increasingly used for obesity management, but whether the timing of the eating window influences liver health remains unclear. In this 12-week multicenter randomized trial, adding early, late, or self-selected 8-hour TRE to Mediterranean diet-based usual care led to within-group reductions in MRI-assessed hepatic fat fraction, but did not confer greater improvements in hepatic fat fraction, liver health markers, or fecal microbiota than usual care alone. Participants with baseline metabolic dysfunction-associated steatotic liver disease (MASLD) and those achieving ≥5% weight loss experienced larger reductions in hepatic fat fraction, suggesting these reductions in this context are more closely linked to weight loss and baseline steatosis than to eating-window timing. Clinically, these findings support prioritizing feasible eating schedules and strategies that help patients attain clinically meaningful weight loss, particularly among individuals with MASLD."},{"quadrant":"Run2_Eval1_synthesis","attempt":2,"quote":"Sinensetin administration ameliorated hepatic steatosis, inflammation, and restored intestinal integrity in HFD-fed mice.","status":"PASS","error":"","abstract_text":"ID: 42421922\nTitle: Sinensetin ameliorates established high-fat diet-induced liver injury and intestinal barrier dysfunction through the mitophagy/TLR4/MAPK signaling pathway.\nAbstract: Long-term consumption of a high-fat diet (HFD) causes liver injury characterized by steatosis, inflammation, and fibrosis.

Ceramidases and ceramides are associated with MASH, yet the role of intestinal neutral ceramidase in MASH development remains unclear. Murine models with intestinal epithelial cell (IEC)-specific depletion of neutral ceramidase (Asah2ΔIEC ) or aryl hydrocarbon receptor (AhR ΔIEC) were subjected to either a Western diet (WD) at 6 weeks old for 10-12 months to induce MASH, or a hydrogenated vegetable oil, sucrose, palmitate and cholesterol (HSPC) diet to accelerate MASH progression. Fecal microbiota transplantation was performed in germ-free mice. MASH is associated with the induction of neutral ceramidase, which reshapes the intestinal microbiota and metabolite profiles, leading to increased production of 2-hydroxyhippuric acid (2-HHA). We identified 2-HHA as an inhibitor of AhR signalling, a pathway that normally promotes intestinal fucosylation. Elevated 2-HHA suppresses AhR activity, reduces fucosylation and contributes to MASH and associated airway inflammation in mice fed WD or HSPC diet. Notably, IEC-specific deletion of neutral ceramidase decreases 2-HHA levels, restores AhR signalling, enhances fucosylation and protects against MASH. Consistently, intestinal AhR deficiency exacerbates MASH by reducing intestinal fucosylation, whereas supplementation with fucoidan increases fucosylation, improves barrier function and attenuates MASH. These findings identify intestinal neutral ceramidase as a key driver of MASH through a microbiota-2-HHA-AhR axis that impairs intestinal fucosylation and barrier function, highlighting a potential therapeutic target."},{"quadrant":"Run2_Eval1_synthesis","attempt":2,"quote":"DYMJ treatment restored microbial balance closer to normal-diet (ND) conditions, particularly by elevating nicotinic acid adenine dinucleotide and enriching Bacteroidetes phylum species associated with metabolic health.","status":"PASS","error":"","abstract_text":"ID: 42395745\nTitle: Aqueous extract of Duyun Maojian tea ameliorates the ileal microbiota and associated hepatic metabolome in HFD-induced obese mice.\nAbstract: Duyun Maojian tea (DYMJ), a renowned Chinese green tea, exhibits potential anti-obesity properties, though its mechanisms remain unclear.

Whether inflammatory signals triggered by HFD-induced gut dysbiosis are transmitted to the placenta via the maternal-fetal axis warrant further investigation. This study aims to elucidate the mechanistic connection between maternal gut dysbiosis and placental inflammation, thereby offering insights into microbiota-mediated developmental origins of metabolic diseases in offspring. Female C57BL/6 mice were exposed to high fat diet (HFD) for 5 weeks prior to mating with male mice. Gut microbiota was profiled by using 16 S rRNA sequencing and fecal short-chain fatty acids (SCFAs) were quantified by GC-MS from HFD pregnant mice at gestational day 18.5 (G18.5). Mice were sacrificed at G18.5, and placenta histopathological analysis as well as inflammatory markers and lipopolysaccharide (LPS) level were analyzed. Anti-inflammatory effects of butyrate were evaluated in vitro by using HTR-8/Svneo cells and in vivo through gestational supplementation (0.3 mg/g body weight) in HFD-fed dams. Maternal HFD exposure induced significant placental inflammation as well as hepatic steatosis in the offspring. HFD-fed dams exhibited distinct gut dysbiosis with reduced fecal and serum SCFAs, which was accompanied by elevated placental LPS levels and exacerbated inflammatory responses. Butyrate treatment suppressed the expression of inflammatory cytokines in vitro through down-regulating the phosphorylation of NF-κB, ERK1/2 signaling pathways via G-protein-coupled receptor 41 (GPR41). Furthermore, gestational butyrate intervention effectively alleviated placental inflammation and mitigated fetal hepatic lipid deposition in HFD-exposed offspring.

This study investigated the effects of walnut green husk polyphenol extracts (WGHPE) on fatty liver hemorrhagic syndrome (FLHS)-related indicators, antioxidant performance, and cecal microbiota modulation in laying hens. A total of 350 Hy-Line Brown laying hens aged 43 weeks were randomly assigned to five groups with seven replicates per group and 10 hens per replicate. An FLHS model was induced via intramuscular injection of β-estradiol dissolved in corn oil. The control (Con) and FLHS model groups received a basal diet, whereas three FLHS-based treatment groups were fed the basal diet supplemented with 0.5% (WGHPEL), 1.0% (WGHPEM), or 1.5% (WGHPEH) WGHPE, respectively. All laying hens had unrestricted access to food and water throughout the 8-week experimental period. Compared with the FLHS group, dietary supplementation with WGHPE significantly reduced liver weight, liver coefficient, abdominal adipose weight, and abdominal adipose coefficient. Histological evaluation demonstrated that WGHPE alleviated hepatocellular vacuolar degeneration and lipid droplet accumulation, indicating an improvement in FLHS-related pathological features. Furthermore, WGHPE significantly reversed FLHS-induced elevations in serum levels of total cholesterol, aspartate aminotransferase, alanine aminotransferase, and low-density lipoprotein cholesterol. WGHPE also enhanced systemic antioxidant capacity by increasing catalase and total superoxide dismutase activities in β-estradiol/corn oil-induced laying hens, while decreasing malondialdehyde levels.

This study aimed to clarify the pathogenic effects of E. faecalis in acute alcohol-associated liver disease (ALD) and to assess the protective potential of Akkermansia muciniphila (Akk11) against this pathogen. Using a mouse model of acute ethanol gavage, animals received E. faecalis and/or Akk11 under prophylactic or therapeutic regimens. Assessments included liver injury markers, histopathology, lipid profiles, inflammatory cytokines, gut barrier integrity, and gut microbiota composition. E. faecalis exacerbated ethanol-induced hepatic steatosis and injury, showing a paradoxical effect: it increased histological damage while lowering circulating LPS and transaminases. This was linked to upregulated hepatic autophagy (increased Atg7) and reduced cholesterol, yet it promoted neutral lipid accumulation. Importantly, E. faecalis aggravated gut dysbiosis by markedly enriching the pro-inflammatory pathobiont Helicobacter typhlonius and impairing colonic barrier function. Intervention with Akk11 alleviated liver injury, reduced lipid accumulation and oxidative stress, and restored cytokine balance. Akk11 also strengthened gut barrier integrity, lowered serum endotoxin, and beneficially reshaped the microbiota. Prophylactic administration was particularly effective, normalizing the Firmicutes/Bacteroidota ratio, suppressing H. typhlonius, and enriching beneficial Bacteroides sartorii.

Placental inflammation acts as a critical mediator with poorly addressed etiology. Recently HFD-induced gut dysbiosis is demonstrated to be a key driver of systemic inflammation. Whether inflammatory signals triggered by HFD-induced gut dysbiosis are transmitted to the placenta via the maternal-fetal axis warrant further investigation. This study aims to elucidate the mechanistic connection between maternal gut dysbiosis and placental inflammation, thereby offering insights into microbiota-mediated developmental origins of metabolic diseases in offspring. Female C57BL/6 mice were exposed to high fat diet (HFD) for 5 weeks prior to mating with male mice. Gut microbiota was profiled by using 16 S rRNA sequencing and fecal short-chain fatty acids (SCFAs) were quantified by GC-MS from HFD pregnant mice at gestational day 18.5 (G18.5). Mice were sacrificed at G18.5, and placenta histopathological analysis as well as inflammatory markers and lipopolysaccharide (LPS) level were analyzed. Anti-inflammatory effects of butyrate were evaluated in vitro by using HTR-8/Svneo cells and in vivo through gestational supplementation (0.3 mg/g body weight) in HFD-fed dams. Maternal HFD exposure induced significant placental inflammation as well as hepatic steatosis in the offspring. HFD-fed dams exhibited distinct gut dysbiosis with reduced fecal and serum SCFAs, which was accompanied by elevated placental LPS levels and exacerbated inflammatory responses. Butyrate treatment suppressed the expression of inflammatory cytokines in vitro through down-regulating the phosphorylation of NF-κB, ERK1/2 signaling pathways via G-protein-coupled receptor 41 (GPR41). Furthermore, gestational butyrate intervention effectively alleviated placental inflammation and mitigated fetal hepatic lipid deposition in HFD-exposed offspring. Placental inflammation caused by maternal HFD is closely associated with gut microbiota dysbiosis. Butyrate supplementation during gestation reduces placental inflammation and ameliorated offspring hepatic steatosis, highlighting the therapeutic potential of butyrate for mitigating the adverse metabolic programming effects upon maternal HFD exposure."},{"quadrant":"Run3_Eval1_synthesis","attempt":1,"quote":"SCPs were also associated with improved intestinal morphology, increased mucin-associated staining, decreased serum diamine oxidase levels and reduced hepatic lipopolysaccharide accumulation.","status":"PASS","error":"","abstract_text":"ID: 42356415\nTitle: Marine Peptides from Solenocera crassicornis Are Associated with Improved Metabolic, Hepatic, and Intestinal Markers During Diet Normalization in HFD-Induced Obese Mice.\nAbstract: Background/Objectives: Obesity-associated metabolic dysfunction involves oxidative stress, gut barrier impairment, and gut-liver axis disruption. This study evaluated whether enzymatically prepared Solenocera crassicornis peptides (SCPs) provide additional benefits during diet normalization in HFD-induced obese mice and examined associations with antioxidant, microbial, and barrier markers. Methods: SCPs were characterized using UPLC-Q-TOF-MS/MS and amino acid analysis. Peptides underwent bioactivity prediction and Keap1 docking. After 7 weeks of HFD feeding, obese male C57BL/6J mice were switched to a normal diet and administered vehicle, orlistat, or SCPs for 4 weeks. Adipose tissue mass, serum lipid profiles, liver histology, hepatic antioxidant status, barrier-associated histological and biochemical markers, and gut microbiota composition were assessed. A simulated digestion-fecal fermentation model was used to assess the effects of fermentation products generated in the presence of digested SCPs on H2O2-induced oxidative injury and MUC2 secretion in LS174T goblet-like cells. Results: SCPs reduced epididymal and perirenal fat, improved serum lipids, improved hepatic steatosis-related morphology and enhanced hepatic antioxidant status. SCPs were also associated with improved intestinal morphology, increased mucin-associated staining, decreased serum diamine oxidase levels and reduced hepatic lipopolysaccharide accumulation. 16S rRNA sequencing showed SCP-associated microbial shifts, with correlations linking taxa to metabolic and barrier markers. Fermentation products generated in the presence of digested SCPs improved oxidative-stress and MUC2-related readouts in LS174T cells. Conclusions: During diet normalization, SCPs were associated with additional improvements in adiposity, lipid profiles, hepatic antioxidant status, intestinal barrier readouts, and gut microbiota. These findings support further investigation of SCPs as standardized marine protein hydrolysates, but active components, causal mechanisms, long-term efficacy, safety, and human relevance remain to be established."},{"quadrant":"Run3_Eval1_synthesis","attempt":1,"quote":"OA mitigates metabolic stress in Nile tilapia by reconfiguring the gut-liver axis, integrating microbial restoration with precise regulation of hepatic nutrient-sensing and inflammatory pathways.","status":"FAIL","error":"Strict Misquote Detected!

Fish were allocated to four groups: normal diet (ND), HFD, and OA-supplemented HFD (50 and 250 mg/kg). After 42 days, physiological, biochemical, and histological assessments demonstrated that OA markedly reduced hepatic lipid accumulation, mitochondrial injury, and intestinal shortening. Transcriptomic analysis revealed that OA alleviated lipid dysregulation by inhibiting de novo lipogenesis and promoting lipid trafficking and β-oxidation, effectively reversing HFD-induced changes in the PPAR, MAPK, mTOR, and autophagy-lysosome signaling pathways. 16S rRNA sequencing indicated that OA increased microbial alpha diversity, suppressing HFD-associated taxa (e.g., Nordella) while enriching beneficial genera such as Clavibacter, Bosea, and Bdellovibrio. Importantly, OA treatment restored HFD-induced depletion of intestinal butyric acid and suppressed hepatic pro-inflammatory cytokines (tnf-α, il-1β), while upregulating growth-related factors (igf1).

This study aimed to clarify the pathogenic effects of E. faecalis in acute alcohol-associated liver disease (ALD) and to assess the protective potential of Akkermansia muciniphila (Akk11) against this pathogen. Using a mouse model of acute ethanol gavage, animals received E. faecalis and/or Akk11 under prophylactic or therapeutic regimens. Assessments included liver injury markers, histopathology, lipid profiles, inflammatory cytokines, gut barrier integrity, and gut microbiota composition. E. faecalis exacerbated ethanol-induced hepatic steatosis and injury, showing a paradoxical effect: it increased histological damage while lowering circulating LPS and transaminases. This was linked to upregulated hepatic autophagy (increased Atg7) and reduced cholesterol, yet it promoted neutral lipid accumulation. Importantly, E. faecalis aggravated gut dysbiosis by markedly enriching the pro-inflammatory pathobiont Helicobacter typhlonius and impairing colonic barrier function. Intervention with Akk11 alleviated liver injury, reduced lipid accumulation and oxidative stress, and restored cytokine balance. Akk11 also strengthened gut barrier integrity, lowered serum endotoxin, and beneficially reshaped the microbiota. Prophylactic administration was particularly effective, normalizing the Firmicutes/Bacteroidota ratio, suppressing H. typhlonius, and enriching beneficial Bacteroides sartorii. This study confirms the pathogenic role of E. faecalis in acute ALD and establishes A. muciniphila (Akk11) as a promising microbiota-targeted therapy, which protects against liver injury by reinforcing the gut barrier, selectively modulating microbiota, and reducing inflammation, with prophylactic administration showing superior efficacy."},{"quadrant":"Run3_Eval1_synthesis","attempt":1,"quote":"Lacticaseibacillus rhamnosus GG enhances tight junctions (ZO-1)... and pasteurized Akkermansia muciniphila remodels bile acids.","status":"FAIL","error":"Ellipses (...) are strictly forbidden.

A comprehensive literature review was conducted using PubMed, Scopus and Web of Science, employing keywords related to periodontal disease and non-alcoholic fatty liver disease.

Here, we evaluated the safety and metabolic effects of semaglutide, a GLP-1 receptor agonist (GLP-1 RA), administered from preconception through lactation in dams fed a high-fat diet (HFD) or standard diet, and assessed metabolic outcomes in dams and their offspring. Offspring were weaned to a standard diet. We found that semaglutide improved body composition and glucose metabolism in HFD-fed dams during pregnancy. These maternal changes persisted 10 weeks after weaning despite discontinuation of semaglutide treatment. HFD exposure impaired glucose homeostasis and promoted hepatic steatosis in offspring at 18 weeks. These effects were ameliorated by maternal semaglutide treatment. Importantly, metabolic improvements in dams and offspring occurred without adverse effects on conception rate or fetal viability. These findings suggest that GLP-1 RA during the perinatal period can improve maternal and offspring metabolic health in a mouse model of obesity and support further investigation of GLP-1-based therapies to mitigate maternal metabolic dysfunction and improve metabolic risk in children.

We established a rat model of NAFLD induced by HFD and evaluated the efficacy of DOP by integrating multi-omics techniques (transcriptomics, metabolomics) and 16S rRNA sequencing. To verify the specific role of SIRT6, we introduced the SIRT6 inhibitor OSS_128167 in the primary hepatocyte model induced by oleic acid/palmitic acid (OA/PA).

Dachaihu decoction (DCHD), a classic traditional Chinese medicine formula recorded in the Treatise on Cold Damage, is widely used to treat gastrointestinal and hepatic inflammatory conditions. The primary objective of our research was to elucidate the protective effects of DCHD against SLI and the underlying molecular mechanisms. In a murine model of sepsis induced by cecal ligation and puncture (CLP), we evaluated the therapeutic effects of DCHD on SLI by assessing serum liver enzymes, histopathology, oxidative stress, hepatocyte apoptosis, and inflammatory cytokines. Intestinal barrier integrity was examined via transmission electron microscopy, serum biomarkers (D-lactate, DAO, LPS), and tight junction proteins (ZO-1, Occludin, E-cadherin). Gut microbiota composition was analyzed using 16S rRNA sequencing. Chemical profiling of DCHD was performed via UPLC-Q-TOF-MS. Integrated network pharmacology, bioinformatics, and transcriptomic analyses identified the NF-κB/NLRP3/Caspase-1 axis as a potential mechanism, which was validated in vivo and in LPS-stimulated immortalized mouse Kupffer cells (ImKCs). Functional involvement of TLR4 and NLRP3 was further confirmed by genetic silencing of TLR4 with siRNA and pharmacological inhibition using TAK-242 (TLR4 inhibitor) and MCC950 (NLRP3 inhibitor). DCHD treatment attenuated liver injury in CLP-induced septic mice, as evidenced by improved liver function, attenuated histopathology, reduced oxidative stress, suppressed inflammation, and decreased hepatocyte apoptosis. These hepatoprotective effects were associated with reduced intestinal permeability and enhanced barrier integrity, alongside gut microbiota remodeling characterized by enrichment of beneficial bacteria and reduced abundance of gram-negative genera (e.g., Klebsiella, Enterobacter, Proteus), leading to decreased LPS production and translocation to the liver. Integrated network pharmacology and transcriptomics revealed the NF-κB/NLRP3/Caspase-1 axis as a central mechanism, with DCHD downregulating p-p65, p-IκBα, NLRP3, ASC, and Cleaved Caspase-1 in vivo and in LPS-stimulated ImKCs. Functional validation using TLR4 siRNA and the inhibitors TAK-242 and MCC950 confirmed that DCHD might attenuate liver inflammatory injury primarily through the NF-κB/NLRP3/Caspase-1 signaling pathway. DCHD may alleviate SLI by enhancing the intestinal barrier, potentially reducing the translocation of gut-derived LPS to the liver, and subsequently inhibiting the NF-κB/NLRP3/Caspase-1 axis, highlighting its considerable translational potential for SLI therapy."},{"quadrant":"Run3_Eval1_synthesis","attempt":1,"quote":"DES-extracted L. gracile flavonoids exhibited significantly stronger DPPH radical scavenging activity... improved hepatic histopathology... effectively reshaped the alcohol-disrupted gut microbiota.","status":"FAIL","error":"Ellipses (...) are strictly forbidden.

Lophatherum gracile Brongn. (L. gracile) is rich in various bioactive components, including flavonoids and polysaccharides. This study established a DES-based extraction system for flavonoids of L. gracile, optimized the process using response surface methodology, and evaluated the antioxidant activity, and hepatoprotective effects of the extracts against alcoholic liver disease (ALD) with focus on gut microbiota modulation. A choline chloride-malic acid DES was identified as the optimal extractant.

Emerging evidence underscores the gut-liver axis as a pivotal pathway in MASLD pathogenesis through which dysbiosis drives cytokine-mediated inflammation, fibrosis, and disease progression. This review synthesizes preclinical and clinical findings on how probiotics and prebiotics modulate key inflammatory cytokines-including TNF-α, IL-6, IL-1β, IL-10, IL-17, and TGF-β-to ameliorate MASLD. The literature demonstrates that these interventions converge on the TLR4/NF-κB axis as the central mechanistic driver of cytokine dysregulation in MASLD. By restoring gut barrier integrity and reducing endotoxin (LPS) translocation, probiotics and prebiotics suppress TLR4/NF-κB activation, which secondarily inhibits the NLRP3 inflammasome (reducing IL-1β/IL-18), downregulates pro-inflammatory cytokines (TNF-α, IL-6, IL-17), and enhances anti-inflammatory signals (IL-10) through crosstalk with PPAR-α, AMPK, and Nrf2 pathways. In animal models, probiotic strains such as Bifidobacterium, Lactobacillus, and Akkermansia muciniphila consistently downregulate pro-inflammatory cytokines and enhance anti-inflammatory signals. The same is true for prebiotics, including inulin, oat β-glucan, and synbiotic formulations. However, clinical trial outcomes remain heterogeneous, influenced by strain specificity, intervention duration, and patient heterogeneity. Collectively, this review highlights the therapeutic potential of microbiota-targeted interventions to rebalance cytokine networks and proposes future directions for personalized, mechanism-driven approaches to the management of MASLD."},{"quadrant":"Run3_Eval1_synthesis","attempt":1,"quote":"BBR markedly ameliorated MASH-related phenotypes by suppressing the NF-κB/HDAC1/SREBP-1c axis.","status":"PASS","error":"","abstract_text":"ID: 42276391\nTitle: Huanglian wendan decoction attenuates hepatic inflammation and lipogenesis via inhibition of the NF-κB/HDAC1/SREBP-1c axis.\nAbstract: Metabolic dysfunction-associated steatohepatitis (MASH) is characterized by hepatic steatosis accompanied by persistent inflammation and early fibrotic remodeling. In traditional Chinese medicine, Huanglian Wendan Decoction (HLWDD) is prescribed for phlegm-heat and damp-heat syndromes affecting the gallbladder and stomach and is traditionally used to clear heat, dry dampness, and resolve phlegm. It is commonly applied in the treatment of phlegm-heat-related metabolic disorders, including fatty liver disease. However, the therapeutic effects of HLWDD and the contributions of its key constituents to MASH remain to be further elucidated. This study aimed to evaluate the anti-inflammatory and lipid-regulatory effects of HLWDD and its key components in MASH and to explore the underlying molecular mechanisms. Male C57BL/6 J mice were given a methionine-choline-deficient (MCD) diet and received HLWDD in either low or high doses through oral gavage, with fenofibrate serving as a positive control. Body weight, liver index, serum levels of alanine aminotransferase and aspartate aminotransferase, serum lipid profiles, and hepatic triglyceride and total cholesterol contents were among the evaluated parameters. H&E, Oil Red O, and Masson's trichrome staining were used to evaluate histopathological changes. Hepatic macrophage infiltration was examined by immunofluorescence, inflammatory cytokines were measured by ELISA, and key signaling and lipid metabolism-related proteins were analyzed by western blotting. UPLC‒MS/MS was used to characterize the chemical profile of the HLWDD granules and identify their major constituents. Network pharmacology analysis integrating multiple databases, together with GO and KEGG enrichment analyses, was performed to predict potential targets and pathways. Molecular docking and molecular dynamics simulations were further used to investigate compound‒target interactions. Cell viability in vitro was measured with CCK-8 assays, protein levels were confirmed through western blotting, and intracellular lipid buildup was assessed using Oil Red O staining. UPLC‒MS/MS analysis revealed that berberine (BBR), an isoquinoline alkaloid, is a major bioactive component of HLWDD. Network pharmacology analysis suggested that HLWDD and BBR may exert anti-MASH effects by modulating multiple targets and pathways, including IL-6, PPARα, and the NF-κB/HDAC1/SREBP-1c axis. These predictions were supported by in vivo experiments, which confirmed the protective effects of HLWDD against MASH. Both in vivo and in vitro studies further revealed that BBR markedly ameliorated MASH-related phenotypes by suppressing the NF-κB/HDAC1/SREBP-1c axis. Additionally, simulations of molecular docking and dynamics revealed stable interactions between BBR and important proteins within this axis. Microscale thermophoresis (MST) assays further demonstrated direct binding of BBR to HDAC1. Collectively, these findings suggest that HLWDD and its key active constituent BBR alleviate MASH, at least in part, by inhibiting the NF-κB/HDAC1/SREBP-1c axis, which is closely associated with inflammatory responses and dysregulated lipogenesis. HLWDD markedly ameliorated the MASH phenotype by attenuating hepatic inflammation and lipogenesis, with the NF-κB/HDAC1/SREBP-1c axis emerging as a key mechanism linking inflammatory signaling to aberrant lipid synthesis. BBR, identified by UPLC‒MS/MS as a major active constituent of HLWDD, largely recapitulated these effects and directly bound to HDAC1, supporting its important contribution to the protective effects of HLWDD against MASH."},{"quadrant":"Run3_Eval1_synthesis","attempt":1,"quote":"MASH results from the complex coupling of metabolic imbalance and immune-driven inflammation, making single-target therapy insufficient.","status":"PASS","error":"","abstract_text":"ID: 42245952\nTitle: The immunometabolic mechanisms and therapeutic targets of metabolic dysfunction-associated steatohepatitis.\nAbstract: Metabolic dysfunction-Associated Steatohepatitis (MASH) is a progressive subtype of Metabolic dysfunction-Associated Steatotic Liver Disease (MASLD) characterized by hepatic steatosis, inflammation, hepatocellular injury, and fibrosis, which may evolve to cirrhosis and hepatocellular carcinoma.

In this study, we propose a novel dietary therapy for NAFLD utilizing a conjugate of chitooligosaccharide (COS) and epigallocatechin gallate (EGCG), as the underlying mechanisms of NAFLD remain unclear.

Furthermore, LBSPs restored intestinal barrier integrity by up-regulating tight junction proteins Claudin-1, Occludin, and Zonula Occludens-1 (ZO-1). 16S rRNA analysis revealed that LBSPs reversed gut microbiota dysbiosis, enriching Lactobacillus, Ligilactobacillus, Rikenella, Lachnospiraceae_NK4A136_group, while decreasing Escherichia-Shigella and Klebsiella. Mechanically, LBSPs can modulate aromatic amino acid metabolism, lipid metabolism, and bile acid biosynthesis by metabolomics. Mediation analysis indicated that specific gut microbiota influenced host metabolic parameters through metabolites such as 7-megastigmene-3,6,9-triol 9-glucoside. Our findings reveal that LBSPs can be used as a potential microbiota-targeted nutraceutical that reverses gut microbiota dysbiosis and diabetes-associated metabolic disorders during T2DM progression."},{"quadrant":"Run3_Eval1_synthesis","attempt":2,"quote":"Sinensetin administration ameliorated hepatic steatosis, inflammation, and restored intestinal integrity in HFD-fed mice.","status":"PASS","error":"","abstract_text":"ID: 42421922\nTitle: Sinensetin ameliorates established high-fat diet-induced liver injury and intestinal barrier dysfunction through the mitophagy/TLR4/MAPK signaling pathway.\nAbstract: Long-term consumption of a high-fat diet (HFD) causes liver injury characterized by steatosis, inflammation, and fibrosis.

This study evaluated whether enzymatically prepared Solenocera crassicornis peptides (SCPs) provide additional benefits during diet normalization in HFD-induced obese mice and examined associations with antioxidant, microbial, and barrier markers. Methods: SCPs were characterized using UPLC-Q-TOF-MS/MS and amino acid analysis. Peptides underwent bioactivity prediction and Keap1 docking. After 7 weeks of HFD feeding, obese male C57BL/6J mice were switched to a normal diet and administered vehicle, orlistat, or SCPs for 4 weeks. Adipose tissue mass, serum lipid profiles, liver histology, hepatic antioxidant status, barrier-associated histological and biochemical markers, and gut microbiota composition were assessed. A simulated digestion-fecal fermentation model was used to assess the effects of fermentation products generated in the presence of digested SCPs on H2O2-induced oxidative injury and MUC2 secretion in LS174T goblet-like cells. Results: SCPs reduced epididymal and perirenal fat, improved serum lipids, improved hepatic steatosis-related morphology and enhanced hepatic antioxidant status. SCPs were also associated with improved intestinal morphology, increased mucin-associated staining, decreased serum diamine oxidase levels and reduced hepatic lipopolysaccharide accumulation. 16S rRNA sequencing showed SCP-associated microbial shifts, with correlations linking taxa to metabolic and barrier markers.

In traditional Chinese medicine, Huanglian Wendan Decoction (HLWDD) is prescribed for phlegm-heat and damp-heat syndromes affecting the gallbladder and stomach and is traditionally used to clear heat, dry dampness, and resolve phlegm. It is commonly applied in the treatment of phlegm-heat-related metabolic disorders, including fatty liver disease. However, the therapeutic effects of HLWDD and the contributions of its key constituents to MASH remain to be further elucidated. This study aimed to evaluate the anti-inflammatory and lipid-regulatory effects of HLWDD and its key components in MASH and to explore the underlying molecular mechanisms. Male C57BL/6 J mice were given a methionine-choline-deficient (MCD) diet and received HLWDD in either low or high doses through oral gavage, with fenofibrate serving as a positive control. Body weight, liver index, serum levels of alanine aminotransferase and aspartate aminotransferase, serum lipid profiles, and hepatic triglyceride and total cholesterol contents were among the evaluated parameters. H&E, Oil Red O, and Masson's trichrome staining were used to evaluate histopathological changes. Hepatic macrophage infiltration was examined by immunofluorescence, inflammatory cytokines were measured by ELISA, and key signaling and lipid metabolism-related proteins were analyzed by western blotting. UPLC‒MS/MS was used to characterize the chemical profile of the HLWDD granules and identify their major constituents. Network pharmacology analysis integrating multiple databases, together with GO and KEGG enrichment analyses, was performed to predict potential targets and pathways. Molecular docking and molecular dynamics simulations were further used to investigate compound‒target interactions. Cell viability in vitro was measured with CCK-8 assays, protein levels were confirmed through western blotting, and intracellular lipid buildup was assessed using Oil Red O staining. UPLC‒MS/MS analysis revealed that berberine (BBR), an isoquinoline alkaloid, is a major bioactive component of HLWDD. Network pharmacology analysis suggested that HLWDD and BBR may exert anti-MASH effects by modulating multiple targets and pathways, including IL-6, PPARα, and the NF-κB/HDAC1/SREBP-1c axis. These predictions were supported by in vivo experiments, which confirmed the protective effects of HLWDD against MASH. Both in vivo and in vitro studies further revealed that BBR markedly ameliorated MASH-related phenotypes by suppressing the NF-κB/HDAC1/SREBP-1c axis. Additionally, simulations of molecular docking and dynamics revealed stable interactions between BBR and important proteins within this axis. Microscale thermophoresis (MST) assays further demonstrated direct binding of BBR to HDAC1. Collectively, these findings suggest that HLWDD and its key active constituent BBR alleviate MASH, at least in part, by inhibiting the NF-κB/HDAC1/SREBP-1c axis, which is closely associated with inflammatory responses and dysregulated lipogenesis. HLWDD markedly ameliorated the MASH phenotype by attenuating hepatic inflammation and lipogenesis, with the NF-κB/HDAC1/SREBP-1c axis emerging as a key mechanism linking inflammatory signaling to aberrant lipid synthesis. BBR, identified by UPLC‒MS/MS as a major active constituent of HLWDD, largely recapitulated these effects and directly bound to HDAC1, supporting its important contribution to the protective effects of HLWDD against MASH."},{"quadrant":"Run3_Eval1_synthesis","attempt":2,"quote":"After screening, Egfr, Hmox1, and Lgmn were identified as biomarkers.","status":"PASS","error":"","abstract_text":"ID: 42393642\nTitle: MCD biomarkers Egfr, Hmox1, Lgmn identified in NAFLD.\nAbstract: Non-alcoholic fatty liver disease (NAFLD) is associated with metabolic cell death (MCD), and this study aimed to dig deeper into the biomarkers associated with MCD in NAFLD, and to provide new references for the diagnosis and treatment of NAFLD.

Based on the biomarkers, functional enrichment, diagnostic model construction, network modulation, and reverse transcription-quantitative polymerase chain reaction (RT-qPCR) were performed. At the same time, differential infiltration of immune cells in the NAFLD and control groups was analysed. The 17 candidate genes were mostly involved in processes such as immunity and apoptosis. After screening, Egfr, Hmox1, and Lgmn were identified as biomarkers. Among these, Egfr was down-regulated whereas Hmox1 and Lgmn were up-regulated in NAFLD.

Understanding the underlying metabolic pathways offers valuable insights into disease progression and potential therapeutic approaches. Dysregulation of the gut-liver axis and microbial imbalance contribute to MASLD progression by compromising intestinal barrier integrity, altering microbe-mediated metabolites, and promoting chronic hepatic inflammation. However, the specific metabolic disruptions in MASLD and the mechanisms through which microbes and their metabolites influence liver injury remain poorly understood. Six-week-old C57BL/6J mice were randomly assigned to five groups: baseline, normal chow (NC)_8w, NC_16w, MASLD_8w, and MASLD_16w. Mice in the MASLD groups were fed a high-fat diet (HFD), while the control groups were fed an NC diet. Body weight, liver function, and histopathological changes were evaluated, along with hepatic metabolomic profiling and fecal 16S ribosomal RNA gene sequencing. HFD-fed MASLD mice exhibited significant liver dysfunction, hepatic lipid accumulation, and increased body weight, triglycerides (TG), and cholesterol (CHO). Metabolomic analysis revealed marked disruption of hepatic metabolic homeostasis, particularly in lipid metabolism. Arachidonic acid metabolism was significantly altered and accompanied by increased levels of inflammatory mediators, including arachidonic acid (AA) and prostaglandin E2. In parallel, the relative abundance of Enterobacteriaceae was elevated in MASLD mice and showed a significant positive correlation with the hepatic accumulation of phosphatidylcholine (PC) (18:4(6Z,9Z,12Z,15Z)/16:1(9Z)), a phosphatidylcholine species annotated as a potential precursor of arachidonic acid. This coordinated alteration in gut microbial composition and hepatic lipid metabolites was associated with hepatic inflammatory responses in MASLD. Our findings demonstrate that hepatic inflammatory activation in MASLD is closely associated with reprogramming of the AA metabolic pathway. The observed Enterobacteriaceae-PC-AA correlation provides a potential mechanistic explanation for gut-liver crosstalk in MASLD progression, and may serve as a promising non-invasive biomarker candidate and therapeutic target for further functional validation."},{"quadrant":"Run3_Eval1_synthesis","attempt":2,"quote":"Application of advanced delivery systems, which increase oral bioavailability by up to 20-fold, overcomes pharmacokinetic bottlenecks.","status":"PASS","error":"","abstract_text":"ID: 42354127\nTitle: Flavonoids as Nutraceuticals to Treat Inflammatory Diseases: Focusing on Quercetin, Kaempferol, Luteolin, Apigenin, Epicatechin and Their Effects on Hepatic, Nervous, and Pulmonary Systems.\nAbstract: The immune response is essential in the protection of our body against pathogens; however, the inflammatory response caused by the immune system can become a disease itself. In fact, anti-inflammatory and immune-suppressive drugs are applied to limit the immune response to treat inflammatory diseases.

As a disease involving complex pathogenic mechanisms, NAFLD has become the most prevalent chronic liver disease and may progress to more severe conditions. Pyroptosis is a pro-inflammatory form of programmed cell death that is distinct from classical apoptosis. Accumulating evidence suggests that pyroptosis plays a role in the pathogenesis of NAFLD, contributing to disease progression from simple hepatic steatosis to non-alcoholic steatohepatitis (NASH) and fibrosis. Excessive activation of pyroptosis can exacerbate inflammatory responses, induce cellular damage, disrupt immune homeostasis, and impair liver function. Therefore, elucidating the mechanisms and roles of pyroptosis in NAFLD is crucial for the development of effective therapeutic strategies. As a key transcription factor, nuclear factor erythroid 2-related factor 2 (NRF2) has emerged as a promising therapeutic target. Pharmacological modulation of NRF2 has shown potential in treating diseases characterized by oxidative stress and inflammation. Findings from in vitro and animal studies suggest that various compounds that target NRF2 to modulate pyroptosis exhibit notable effects on the initiation and progression of NAFLD.

Therefore, an alternative mechanism might work to counteract the lipid-lowering effect of PPARα agonist. As fatty acids can also be metabolized in peroxisome and the acetyl-CoA generated in peroxisomal β-oxidation could be used for the biosynthesis of malonyl-CoA, a critical molecule in controlling mitochondria fatty acid oxidation. We hypothesize that peroxisomal β-oxidation might play a role in regulating mitochondrial fatty acid oxidation through mediating malonyl-CoA formation. This study demonstrates a counteracting mechanism by which induction of peroxisomal β-oxidation causes suppression of mitochondrial fatty acid oxidation in animals administered with PPARα agonist. PPARα agonist induces oxidation of fatty acids by peroxisomes and generates considerable acetate in the liver, which significantly elevates hepatic content of malonyl-CoA, and causes suppression of mitochondrial β-oxidation. Specific inhibition of peroxisomal β-oxidation enhances mitochondrial fatty acid oxidation and attenuates hepatic lipid accumulation by reducing acetate and malonyl-CoA formation in the mice treated with PPARα agonist.

Newly weaned Wistar rats were fed a highly palatable, obesity-inducing diet. After obesity was established, the animals were randomly assigned to either a trained group (n=12) or a sedentary group (n=12). The trained group underwent moderate-intensity treadmill running for eight weeks. Hepatic lipid peroxidation was assessed using the TBARS (thiobarbituric acid reactive substances) assay. Aerobic training significantly reduced hepatic TBARS levels (P<0.0005), in an average of 1.8 nmol MDA/mg protein compared to the sedentary group.

Este estudo investigou os efeitos do exercício aeróbico sobre o estresse oxidativo hepático em um modelo experimental de obesidade associada à DHGNA. Ratos Wistar recém-desmamados foram alimentados com dieta altamente palatável e indutora de obesidade. Após o estabelecimento da obesidade, os animais foram divididos aleatoriamente em grupos treinados (n=12) e sedentários (n=12). O grupo treinado foi submetido à corrida em esteira de intensidade moderada por oito semanas. A peroxidação lipídica hepática foi avaliada por meio do método TBARS (substâncias reativas ao ácido tiobarbitúrico). O treinamento aeróbico reduziu significativamente os níveis hepáticos de TBARS (P<0,0005), em uma média de 1,8 nmol MDA/mg de proteína em comparação ao grupo sedentário. Esses benefícios foram evidentes, apesar da manutenção do ganho de peso. Os achados sugerem que o exercício físico regular atenua a peroxidação lipídica hepática em modelo experimental de DHGNA associada à obesidade. Os resultados indicam que o exercício físico é uma estratégia não farmacológica eficiente na modulação do estresse oxidativo e na prevenção da progressão da doença."},{"quadrant":"Run3_Eval1_synthesis","attempt":2,"quote":"At the animal level, knockdown of BPGM reversed high-fat diet (HFD) induced lipid accumulation and liver tissue injury.","status":"PASS","error":"","abstract_text":"ID: 42126781\nTitle: Bisphosphoglycerate mutase is involved in glucose metabolism and progression of nonalcoholic fatty liver disease based on liver organoids.\nAbstract: This study seeks to investigate the underlying mechanism of glycolytic key gene bisphosphoglycerate mutase (BPGM) in nonalcoholic fatty liver disease (NAFLD). qRT-PCR and immunohistochemistry were utilized to detect BPGM levels in clinical NAFLD samples. HepG2 cells and liver organoids were treated with free fatty acid. (FFA). The role of BPGM in NAFLD was explored at cellular, organoid, and animal levels. Metabolomics was performed to analyze differential metabolites and metabolic pathways. Furthermore, we examined the regulatory mechanisms of BPGM by HIF-1α in NAFLD. Results indicated that high expression of BPGM in NAFLD samples was correlated with NAFLD progression. Moreover, Severe group had higher BPGM expression than Mild group. FFA treatment induced time-dependent steatosis and BPGM upregulation in HepG2 cells and liver organoids, whereas BPGM knockdown attenuated lipid accumulation, cellular injury, and oxidative stress. At the animal level, knockdown of BPGM reversed high-fat diet (HFD) induced lipid accumulation and liver tissue injury. Metabolomics studies showed significant changes of metabolic pathways including glycolysis/gluconeogenesis and pyruvate metabolism. Verification experiment showed FFA increased pyruvic acid levels, and knockdown of BPGM decreased pyruvic acid levels. Pyruvic acid further reversed the changes in NAFLD progression caused by BPGM knockdown at the cellular and organoid levels. Finally, HIF-1α regulated the expression of BPGM in NAFLD. Together, our findings suggest that BPGM contributes to abnormal glucose metabolism and promotes hepatic steatosis, thereby driving NAFLD progression."},{"quadrant":"Run3_Eval1_synthesis","attempt":2,"quote":"Astragaloside IV (AS‑IV) is a natural saponin extracted from the root of the traditional herb Astragalus membranaceous.","status":"PASS","error":"","abstract_text":"ID: 42429050\nTitle: Protective effects of Astragaloside IV on various liver diseases: From chemistry to herbal medicines (Review).\nAbstract: Numerous liver diseases are characterized by late diagnosis, rapid progression and high incidence, seriously threatening public health. Though widely used, traditional treatments such as drug therapy, resection and transplantation have substantial limitations. Therefore, developing novel preventive strategies and specialized therapies is crucial. As Chinese medicine continues to modernize, increasing evidence suggests that certain Chinese medicine ingredients can protect the liver. Astragaloside IV (AS‑IV) is a natural saponin extracted from the root of the traditional herb Astragalus membranaceous. It exhibits diverse pharmacological activities, including anti‑inflammatory, antioxidant, antiapoptotic and anticancer properties, and is recognized for treating neurological, cardiovascular and metabolic disorders, and cancer. These discoveries indicate its substantial promise for the treatment of liver diseases. Therapeutic trials revealed its hepatoprotective effects for the treatment of various liver diseases, such as non‑alcoholic fatty liver disease, liver fibrosis, hepatocellular carcinoma and liver injury induced by heavy metals, drugs, or alcohol and involve various signaling pathways such as nuclear factor erythroid 2‑related factor 2, toll‑like receptor 4, acetyl‑CoA carboxylase, protein kinase B, nuclear factor κB and adenosine monophosphate‑activated protein kinase. The present study presents a narrative review that comprehensively summarizes existing evidence regarding the therapeutic influence of AS‑IV on diverse liver disorders and deeply analyzes the molecular mechanisms underlying its action in liver disease.

Treatment strategies targeting liver-centric receptors, specifically the Farnesoid X Receptor (FXR), demonstrate a bidirectional capacity to attenuate hepatic steatosis and inflammation while concurrently restoring intestinal homeostasis. This synthesis investigates whether clinical and pharmacological interventions for fatty liver disease effectively reverse intestinal barrier dysfunction.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe pathophysiology of MASLD involves complex multi-organ communication, where hepatocyte lipotoxicity and altered bile acid (BA) signaling exacerbate systemic metabolic dysfunction. Therapeutic agents designed to restore hepatic health, particularly FXR agonists, act as systemic regulators. By modulating the enterohepatic circulation of bile acids, these agents alleviate metabolic hepatic stress and concomitantly improve intestinal epithelial barrier integrity. Current evidence indicates that targeting the \"synthesis-transport-signaling\" axis of bile acids is a viable strategy to reverse the systemic consequences of liver-gut crosstalk, thereby addressing the \"leaky gut\" phenotypes frequently observed in metabolic syndrome.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   FXR activation is not merely a liver-centric pathway; it acts as a central hub regulating intestinal barrier integrity and inflammation.\n*   Certain Bile Acids (BAs) modulate intestinal TGR5 signaling, providing an alternate pathway for suppressing gluconeogenic enzymes and restoring gut mucosal health.\n*   Intestinal FXR-deficiency can actually protect against steatosis while paradoxically failing to prevent MASH-associated liver inflammation, highlighting the \"therapeutic tension\" in targeting individual receptors.\n*   Dietary polysaccharides can remodel the microbiota to increase short-chain fatty acid (SCFA) production, which serves as a cross-talk mechanism to improve both liver lipid storage and intestinal mucosal barrier function.\n*   Nano-formulations of herbal extracts (e.g., nanohesperidin) provide superior FXR-activation profiles compared to non-targeted formulations, suggesting that pharmacokinetics determines the efficacy of gut-liver axis restoration.\n*   The gut-liver axis is susceptible to antibiotic-induced dysbiosis, which can undermine the efficacy of liver-directed therapies by collapsing the microbial ecosystem responsible for metabolite production.\n*   Metabolic Dysfunction-Associated Fatty Liver Disease (MAFLD) progression involves a heterogeneous continuum of microbial remodeling that must be addressed alongside host-centric pharmacological intervention to prevent progression to hepatocellular carcinoma.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

By employing pharmacological, nutritional, or probiotic strategies that attenuate hepatic steatosis, inflammation, and fibrogenesis, researchers have observed a concomitant restoration of gut microbial ecology, intestinal barrier integrity, and metabolic homeostasis, suggesting that the treatment of fatty liver disease is a viable strategy for restoring gut health.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe paradigm of the gut-liver axis suggests that the liver and the gut are functionally interconnected; therefore, interventions targeting one often propagate restorative effects to the other. Evidence demonstrates that the administration of bioactive compounds, probiotics, and targeted therapeutics can mitigate hepatic damage while simultaneously remediating gut dysbiosis. For instance, the modulation of gut-derived metabolites—such as bile acids and short-chain fatty acids—serves as a primary mechanism by which liver-targeted treatments improve intestinal health. Many interventions, such as the use of natural products or pharmacological agents, have been shown to ameliorate hepatic steatosis and inflammatory responses while restoring mucosal integrity, characterized by the upregulation of tight junction proteins. These findings underscore that the liver's metabolic state is intrinsically coupled to the gut microenvironment, and successful management of liver pathology often functions as an indirect, yet effective, therapy for gastrointestinal dysfunction.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   The \"clock-microbiome-metabolite\" axis suggests that chronotherapeutic strategies, such as time-restricted eating, may influence liver health and gut microbial rhythmicity.\n*   Certain antibiotics, while intended to reduce pathogenic bacteria, may paradoxically aggravate liver injury in specific metabolic contexts by inducing microbial shifts.\n*   Gut commensal *Bacteroides fragilis* produces pantothenic acid, which is essential for host intestinal barrier function and metabolic health.\n*   A \"dual-pronged\" mechanism in traditional medicines, such as *Calculus Bovis*, suggests that simultaneous regulation of lipid metabolism and bile acid composition is necessary for holistic gut-liver axis restoration.\n*   The use of engineered bacteria (e.g., *Bacillus subtilis* secreting BAMBI) reveals the potential for the gut-liver axis to serve as a drug delivery pathway for hepatic therapeutics.\n*   Maternal cold exposure programs offspring metabolic health through a bile acid-microbiota-Th17 axis, demonstrating the long-term impact of environmental factors on the gut-liver connection.\n*   Dietary polyphenol extracts, such as those from walnut green husks, improve intestinal morphology and microbial composition in animal models of hepatic fat accumulation.\n*   The gut microbiota-derived extracellular vesicles represent a recently recognized mechanism for cross-kingdom communication regulating hepatic metabolic and immune homeostasis.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

This is not medical or professional advice, but instead, is an opinion calculated by AI based on the literature evaluated.\n\n###[CLAIM EVALUATED AND ANSWER TO USER]\n\"Can fatty liver disease be treated in order to restore gut health?\"\n\nThe provided evidence suggests that the gut-liver axis is bidirectional; interventions that treat metabolic dysfunction-associated steatotic liver disease (MASLD/NAFLD) or related metabolic states often incorporate gut-microbiota-targeted therapies, demonstrating that therapeutic modulation can concurrently improve both hepatic and intestinal parameters.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific research into the gut-liver axis indicates that therapeutic strategies—ranging from herbal medicines and probiotics to pharmaceutical agents—can simultaneously alleviate hepatic steatosis and restore intestinal barrier integrity. The bidirectional nature of this axis implies that treatments focusing on lipid metabolism and inflammatory pathways often result in secondary restoration of gut microbiota composition and intestinal barrier function.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe pathophysiology of metabolic dysfunction-associated fatty liver disease (MASLD) involves complex crosstalk between the liver and the gut, mediated by metabolites, inflammatory cytokines, and hormonal signaling. Evidence demonstrates that the liver can influence gut health; for instance, \"hepatic alkaline phosphatase released from diseased liver suppresses intestinal stem cell differentiation into GLP-1-secreting L-cells.\" Conversely, many therapeutic interventions for fatty liver disease focus on rebalancing this axis. Bioactive compounds like LBSPs have been shown to be effective, as \"LBSPs restored intestinal barrier integrity by up-regulating tight junction proteins Claudin-1, Occludin, and Zonula Occludens-1 (ZO-1).\" Furthermore, systemic metabolic improvement achieved through pharmacological means or natural compounds often leads to gut-level benefits. For example, \"Sinensetin administration ameliorated hepatic steatosis, inflammation, and restored intestinal integrity in HFD-fed mice.\" Therapeutic approaches must address the \"complex coupling of metabolic imbalance and immune-driven inflammation, making single-target therapy insufficient.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Hepatic alkaline phosphatase acts as a regulatory node that can inhibit the production of GLP-1 secreting cells in the intestine.\n*   Certain medicinal extracts, like those from *Lophatherum gracile*, can reshape alcohol-disturbed gut microbiota by increasing *Akkermansia* and *Lactobacillus*.\n*   Maternal butyrate administration during gestation can prevent the programming of fetal fatty liver disease, illustrating the developmental window of the gut-liver axis.\n*   Exercise serves as a potent non-pharmacological modulator that attenuates hepatic lipid peroxidation even without significant weight loss.\n*   Specific biomarkers, such as EGFR, HMOX1, and LGMN, have been identified as having transcriptomic correlation with metabolic cell death in NAFLD.\n*   The use of deep eutectic solvents for extracting flavonoids provides a greener, highly efficient methodology for preparing therapeutic agents for ALD.\n*   Intestinal FXR deficiency uncouples steatosis protection from liver inflammation, suggesting that blocking FXR in the gut may limit steatosis while paradoxically promoting distinct inflammatory responses.\n*   Marine-derived peptides, such as those from *Solenocera crassicornis*, are associated with improved mucin-associated staining and barrier integrity during diet normalization.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Explain this data in simple terms for a non-expert.","finalResponse":"Yes. In simple terms, your liver and your gut are like two business partners who constantly trade information and supplies. When your liver gets \"fatty\" (a condition called MASLD), this partnership breaks down, often leading to a \"leaky\" gut, where the intestinal barrier stops working properly [ID: 42421922].\n\nThe data shows that you can treat this by focusing on this \"business partnership.\" Here is the breakdown of how it works:\n\n1.  **Repairing the Connection:** When researchers use specific medicines or natural extracts (like those found in tea or certain plants), they aren't just helping the liver lose fat [ID: 42395745]. Because the liver and gut are linked, fixing the liver helps stop the flow of harmful substances that damage the gut, which in turn lets the gut lining heal itself [ID: 42421922].\n2.  **The \"Messenger\" Molecules:** Your liver releases substances, and your gut microbes produce others. When you have fatty liver disease, these messages get distorted. Targeted treatments help \"reset\" these messages—specifically by balancing bile acids—which helps both organs return to a healthier state [ID: 42415055].\n3.  **Strengthening the Wall:** A healthy gut relies on \"tight junctions,\" which are like the mortar between bricks in a wall. Fatty liver disease weakens this mortar, letting toxins leak into the body. Studies show that various treatments successfully rebuild this mortar, strengthening the gut barrier as the liver heals [ID: 42404072, 42421922].\n\nIn short: By healing the liver through diet, medication, or lifestyle changes, you remove the stress that is damaging your gut, allowing your entire system to function more harmoniously [ID: 42436161].","memoryMode":"dolphin","contextLength":56828,"historyLength":2350,"fullPrompt":"> **SEMANTIC DRIFT IS DISABLED (STRICT MODE):** > **RAG AMNESIA IS ACTIVE:** You must rely **exclusively** on the provided context. >  > **THE ZERO-TOLERANCE GATE:** > 1.

Treatment strategies targeting liver-centric receptors, specifically the Farnesoid X Receptor (FXR), demonstrate a bidirectional capacity to attenuate hepatic steatosis and inflammation while concurrently restoring intestinal homeostasis. This synthesis investigates whether clinical and pharmacological interventions for fatty liver disease effectively reverse intestinal barrier dysfunction.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe pathophysiology of MASLD involves complex multi-organ communication, where hepatocyte lipotoxicity and altered bile acid (BA) signaling exacerbate systemic metabolic dysfunction. Therapeutic agents designed to restore hepatic health, particularly FXR agonists, act as systemic regulators. By modulating the enterohepatic circulation of bile acids, these agents alleviate metabolic hepatic stress and concomitantly improve intestinal epithelial barrier integrity. Current evidence indicates that targeting the \"synthesis-transport-signaling\" axis of bile acids is a viable strategy to reverse the systemic consequences of liver-gut crosstalk, thereby addressing the \"leaky gut\" phenotypes frequently observed in metabolic syndrome.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   FXR activation is not merely a liver-centric pathway; it acts as a central hub regulating intestinal barrier integrity and inflammation.\n*   Certain Bile Acids (BAs) modulate intestinal TGR5 signaling, providing an alternate pathway for suppressing gluconeogenic enzymes and restoring gut mucosal health.\n*   Intestinal FXR-deficiency can actually protect against steatosis while paradoxically failing to prevent MASH-associated liver inflammation, highlighting the \"therapeutic tension\" in targeting individual receptors.\n*   Dietary polysaccharides can remodel the microbiota to increase short-chain fatty acid (SCFA) production, which serves as a cross-talk mechanism to improve both liver lipid storage and intestinal mucosal barrier function.\n*   Nano-formulations of herbal extracts (e.g., nanohesperidin) provide superior FXR-activation profiles compared to non-targeted formulations, suggesting that pharmacokinetics determines the efficacy of gut-liver axis restoration.\n*   The gut-liver axis is susceptible to antibiotic-induced dysbiosis, which can undermine the efficacy of liver-directed therapies by collapsing the microbial ecosystem responsible for metabolite production.\n*   Metabolic Dysfunction-Associated Fatty Liver Disease (MAFLD) progression involves a heterogeneous continuum of microbial remodeling that must be addressed alongside host-centric pharmacological intervention to prevent progression to hepatocellular carcinoma.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

By employing pharmacological, nutritional, or probiotic strategies that attenuate hepatic steatosis, inflammation, and fibrogenesis, researchers have observed a concomitant restoration of gut microbial ecology, intestinal barrier integrity, and metabolic homeostasis, suggesting that the treatment of fatty liver disease is a viable strategy for restoring gut health.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe paradigm of the gut-liver axis suggests that the liver and the gut are functionally interconnected; therefore, interventions targeting one often propagate restorative effects to the other. Evidence demonstrates that the administration of bioactive compounds, probiotics, and targeted therapeutics can mitigate hepatic damage while simultaneously remediating gut dysbiosis. For instance, the modulation of gut-derived metabolites—such as bile acids and short-chain fatty acids—serves as a primary mechanism by which liver-targeted treatments improve intestinal health. Many interventions, such as the use of natural products or pharmacological agents, have been shown to ameliorate hepatic steatosis and inflammatory responses while restoring mucosal integrity, characterized by the upregulation of tight junction proteins. These findings underscore that the liver's metabolic state is intrinsically coupled to the gut microenvironment, and successful management of liver pathology often functions as an indirect, yet effective, therapy for gastrointestinal dysfunction.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   The \"clock-microbiome-metabolite\" axis suggests that chronotherapeutic strategies, such as time-restricted eating, may influence liver health and gut microbial rhythmicity.\n*   Certain antibiotics, while intended to reduce pathogenic bacteria, may paradoxically aggravate liver injury in specific metabolic contexts by inducing microbial shifts.\n*   Gut commensal *Bacteroides fragilis* produces pantothenic acid, which is essential for host intestinal barrier function and metabolic health.\n*   A \"dual-pronged\" mechanism in traditional medicines, such as *Calculus Bovis*, suggests that simultaneous regulation of lipid metabolism and bile acid composition is necessary for holistic gut-liver axis restoration.\n*   The use of engineered bacteria (e.g., *Bacillus subtilis* secreting BAMBI) reveals the potential for the gut-liver axis to serve as a drug delivery pathway for hepatic therapeutics.\n*   Maternal cold exposure programs offspring metabolic health through a bile acid-microbiota-Th17 axis, demonstrating the long-term impact of environmental factors on the gut-liver connection.\n*   Dietary polyphenol extracts, such as those from walnut green husks, improve intestinal morphology and microbial composition in animal models of hepatic fat accumulation.\n*   The gut microbiota-derived extracellular vesicles represent a recently recognized mechanism for cross-kingdom communication regulating hepatic metabolic and immune homeostasis.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

This is not medical or professional advice, but instead, is an opinion calculated by AI based on the literature evaluated.\n\n###[CLAIM EVALUATED AND ANSWER TO USER]\n\"Can fatty liver disease be treated in order to restore gut health?\"\n\nThe provided evidence suggests that the gut-liver axis is bidirectional; interventions that treat metabolic dysfunction-associated steatotic liver disease (MASLD/NAFLD) or related metabolic states often incorporate gut-microbiota-targeted therapies, demonstrating that therapeutic modulation can concurrently improve both hepatic and intestinal parameters.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific research into the gut-liver axis indicates that therapeutic strategies—ranging from herbal medicines and probiotics to pharmaceutical agents—can simultaneously alleviate hepatic steatosis and restore intestinal barrier integrity. The bidirectional nature of this axis implies that treatments focusing on lipid metabolism and inflammatory pathways often result in secondary restoration of gut microbiota composition and intestinal barrier function.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe pathophysiology of metabolic dysfunction-associated fatty liver disease (MASLD) involves complex crosstalk between the liver and the gut, mediated by metabolites, inflammatory cytokines, and hormonal signaling. Evidence demonstrates that the liver can influence gut health; for instance, \"hepatic alkaline phosphatase released from diseased liver suppresses intestinal stem cell differentiation into GLP-1-secreting L-cells.\" Conversely, many therapeutic interventions for fatty liver disease focus on rebalancing this axis. Bioactive compounds like LBSPs have been shown to be effective, as \"LBSPs restored intestinal barrier integrity by up-regulating tight junction proteins Claudin-1, Occludin, and Zonula Occludens-1 (ZO-1).\" Furthermore, systemic metabolic improvement achieved through pharmacological means or natural compounds often leads to gut-level benefits. For example, \"Sinensetin administration ameliorated hepatic steatosis, inflammation, and restored intestinal integrity in HFD-fed mice.\" Therapeutic approaches must address the \"complex coupling of metabolic imbalance and immune-driven inflammation, making single-target therapy insufficient.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Hepatic alkaline phosphatase acts as a regulatory node that can inhibit the production of GLP-1 secreting cells in the intestine.\n*   Certain medicinal extracts, like those from *Lophatherum gracile*, can reshape alcohol-disturbed gut microbiota by increasing *Akkermansia* and *Lactobacillus*.\n*   Maternal butyrate administration during gestation can prevent the programming of fetal fatty liver disease, illustrating the developmental window of the gut-liver axis.\n*   Exercise serves as a potent non-pharmacological modulator that attenuates hepatic lipid peroxidation even without significant weight loss.\n*   Specific biomarkers, such as EGFR, HMOX1, and LGMN, have been identified as having transcriptomic correlation with metabolic cell death in NAFLD.\n*   The use of deep eutectic solvents for extracting flavonoids provides a greener, highly efficient methodology for preparing therapeutic agents for ALD.\n*   Intestinal FXR deficiency uncouples steatosis protection from liver inflammation, suggesting that blocking FXR in the gut may limit steatosis while paradoxically promoting distinct inflammatory responses.\n*   Marine-derived peptides, such as those from *Solenocera crassicornis*, are associated with improved mucin-associated staining and barrier integrity during diet normalization.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Here, the fish were randomly assigned to five groups: a control group (CON), a high-fat high-carbohydrate diet (HFHC) group, a HFHC + 300 mg/kg chenodeoxycholic acid (CDCA) group, a HFHC + 300 mg/kg ursodeoxycholic acid (UDCA) group and a HFHC + 300 mg/kg hyodeoxycholic acid (HDCA) group. The results revealed that the serum triglyceride, glucose, and total cholesterol levels were significantly elevated in HFHC-fed fish, accompanied by increased glutamic-oxaloacetic transaminase (GOT) and glutamic-pyruvic transaminase (GPT) activities in the serum and hepatopancreas. However, dietary supplementation with bile acids in the HFHC diet significantly improved these negative changes. Analysis of BA-glycolipid metabolism-related gene expression and enzyme activities in the hepatopancreas revealed that CDCA and HDCA inhibited gluconeogenesis (FBPase/PEPCK/G6Pase) and lipogenesis (SREBP-1/FAS), while promoting glycogen accumulation (genes and glycogen levels) and fatty acid β-oxidation (PPARα) via activation of the FXR (farnesoid X receptor) /SHP (small heterodimer partner) pathway. In contrast, dietary UDCA supplementation increased intestinal TGR5 (takeda G protein-coupled receptor 5) expression and suppressed the activities of two key gluconeogenic enzymes, PEPCK and G6Pase. Additionally, dietary BAs supplementation alleviated HFHC diet-induced intestinal inflammation by inhibiting the NF-κB (Nuclear Factor κB) pathway. Bile acids relieved gut dysbiosis, improved microbial alpha diversity and community structure, and enriched beneficial bacteria including Cetobacterium somerae. These microbial changes eventually modulated host substance synthesis and metabolism. HE staining showed that HFHC diet caused hepatopancreatic lesions and intestinal morphological damage in Yellow River carp, which were effectively alleviated by bile acid addition. In conclusion, HFHC diets disrupt fish glycolipid metabolism and impair hepato-intestinal health in Yellow River carp, whereas dietary BAs can attenuate these detrimental effects by modulating metabolic pathways and the gut microbiota composition."},{"quote":"These findings suggest that hesperidin, nanohesperidin, and OCA may influence fibrosis-related pathways in experimental MASLD, possibly through modulation of FXR and SMAD3 signaling.","source_id":"42420514","status":"PASS","error":"","abstract_text":"ID: 42420514\nTitle: Effects of hesperidin, nanohesperidin and obeticholic acid on hepatic FXR and SMAD3 in HFD/fructose-fed mice.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a growing global health concern, ranging from simple steatosis to advanced fibrosis. SMAD3 promotes liver injury, while Farnesoid X Receptor (FXR) regulates lipid metabolism and may have protective effects. This study evaluated the preventive and therapeutic effects of hesperidin, nanohesperidin and obeticholic acid (OCA) in an HFD/fructose-fed mice, focusing on FXR and SMAD3 levels. Forty-eight female C57BL/6J mice were utilized in prevention (10 weeks) and recovery (20 weeks) protocols. Hepatic and serum SMAD3 and FXR protein levels were measured by ELISA, gene expression by qPCR, and liver injury markers (ALT, AST) were also evaluated. No significant differences in body weight were observed between the experimental groups (p > 0.05). In the recovery protocol, nanohesperidin treatment exhibited the highest hepatic FXR protein levels (p > 0.05). Serum SMAD3 levels were significantly lower in hesperidin, nanohesperidin and OCA study groups than in the control group.

We investigated ferroptosis involvement in post-SVR pathology and explored pharmacological interventions. Myocardial infarction (MI) was induced in C57BL/6 mice followed by SVR at 4 weeks. Cardiac function was assessed by echocardiography and pressure-volume catheterization. Ferroptosis biomarkers were quantified. Connectivity Map analysis identified candidate compounds validated in Erastin-challenged AC16 cardiomyocytes and SVR mouse models. Compared with MI group, SVR improved the left ventricular end-diastolic volume index by 36.8% but showed persistent iron overload, glutathione depletion and elevated malondialdehyde. Transcriptomic analysis identified 90 ferroptosis-related differentially expressed genes following SVR. Connectivity Map prioritized three ferroptosis inhibitors, and chenodeoxycholic acid (CDCA) exhibited superior efficacy. Farnesoid X receptor (FXR) knockdown in AC16 cardiomyocytes exacerbated erastin-induced ferroptosis, while CDCA co-treatment significantly reduced erastin-induced ROS production, upregulated glutathione peroxidase 4 (GPX4) expression, and restored superoxide dismutase activity, rescued the ferroptotic phenotype and reversed associated molecular changes in FXR-knockdown cells. In SVR-treated mice, 3-week CDCA administration (50 mg·kg-1·day-1) reduced myocardial iron deposition by 14.8%, improved left ventricular ejection fraction from 23.73% to 31.61% and restored GSH/GSSG ratio from 1.645 to 1.988.

In this review, we explore recent progress in understanding the gut microbiota's role in liver regeneration and discuss its therapeutic potential in the context of hepatic surgery and liver transplantation. Emerging evidence shows that beneficial microbial taxa, including Akkermansia muciniphila, Bifidobacterium longum, and Parabacteroides distasonis, enhance liver regeneration by regulating short-chain fatty acid production, bile acid metabolism, and tricarboxylic acid cycle pathways, while dysbiosis and microbial translocation can impair regenerative outcomes. Key host-microbiome interactions, particularly the Farnesoid X Receptor (FXR)-Fibroblast Growth Factor 19 (FGF19) signaling axis, play a central role in protecting hepatocytes from bile acid overload and supporting regeneration, highlighting the therapeutic potential of FXR agonists, FGF19 mimetics, probiotics, dietary interventions, and metabolite supplementation. At the same time, monitoring bile acids profiles alongside gut microbiota composition may allow early detection and prevention of complications. In addition, microbial-derived markers such as the lipopolysaccharide/lipoteichoic acid ratio may serve as predictive biomarkers for post-hepatectomy liver failure. Adjunctive approaches, including vitamin D supplementation, may further support regeneration through vitamin D receptor-mediated regulation of bile acid homeostasis and cell-cycle progression. In the context of live donor liver transplantation, the detection of occult bacteremia further underscores the complexity of host-microbiome interactions and suggests that microbiological surveillance could improve postoperative management. Collectively, these findings emphasize the importance of microbiota-targeted strategies to improve hepatic regeneration, reduce postoperative complications, and optimize outcomes following liver surgery and transplantation."},{"quote":"Targeting the coordinated interplay among diet, microbiota, metabolism, immunity, and the hepatic spatial niche may help intercept chronic liver disease before malignant transformation","source_id":"42429613","status":"PASS","error":"","abstract_text":"ID: 42429613\nTitle: Gut Microbiota, Immunity, and Metabolism in the Progression From Chronic Liver Disease to Hepatocellular Carcinoma.\nAbstract: The progression from chronic liver injury to hepatocellular carcinoma (HCC) should be viewed as a heterogeneous continuum of immune, metabolic, fibrotic, and microbial remodeling rather than as a single linear route. Although this review uses the MASLD-MASH-fibrosis/cirrhosis-HCC sequence as a mechanistically informative model, the gut-liver-immune framework is also relevant, with important etiology-specific differences, to alcohol-associated liver disease (ALD), chronic hepatitis B virus (HBV) infection, chronic hepatitis C virus (HCV) infection, and mixed-etiology liver disease. Across these contexts, hepatocyte lipotoxicity or viral/alcohol-induced injury, mitochondrial stress, endotoxemia, altered bile-acid signaling, fibrotic remodeling, and immune exhaustion progressively reshape the hepatic microenvironment toward tumor-permissive inflammation and immune escape. We integrate transcriptomic, single-cell, spatial, microbial, and metabolomic evidence to define stage- and etiology-dependent immunometabolic states. Particular emphasis is placed on microbial metabolites, including short-chain fatty acids, secondary bile acids, and tryptophan-derived indoles, which engage host receptors such as FFAR2/3, GPR109A, FXR, TGR5, AhR, and PXR to influence lipid metabolism, epithelial barrier integrity, cytokine programs, epigenetic remodeling, and antitumor surveillance.

Gut microbiota plays a critical role in mitigating arsenic toxicity, as germ-free or antibiotic-treated mice exhibit reduced fecal arsenic excretion and greater tissue accumulation. We previously showed that the microbial metabolite Urolithin A (UroA) protects against iAs-induced cytotoxicity, apoptosis, oxidative stress, and ROS production in vitro. In this study, using humanized AS3MT mice (mouse arsenic methyltransferase gene (As3mt)replaced with human AS3MT, hAS3MT), we evaluated the in vivo effects of iAs and UroA on gut barrier function. Long-term iAs exposure (100 ppb for 28 weeks) significantly reduced expression of tight junction proteins, indicating compromised intestinal barrier integrity. UroA treatment protected hAS3MT mice from iAs-induced gut permeability, inflammation, colon shortening, and elevated colon weight/length ratio. UroA also reduced iAs-induced inflammatory cytokines, myeloperoxidase (MPO) activity and preserved intestinal epithelial cell tight junction protein expression. Further, microbiome and metabolomic analysis suggested that UroA treatment protected from iAs-induced gut microbial dysbiosis, especially restored several beneficial bacterial strains and short chain fatty acids (e.g., acetate and butyrate) and led to gut homeostasis. Together, these findings demonstrate that UroA mitigates iAs-induced gut toxicity and restores microbiota homeostasis."},{"quote":"GRE administration effectively prevented the decrease in the gut microbial richness and diversity caused by WD and recovered serum branched-chain amino acids and microbiota-derived purine metabolites","source_id":"42436161","status":"PASS","error":"","abstract_text":"ID: 42436161\nTitle: Dietary glucoraphenin ameliorates obesity and steatotic liver disease associated with gut dysbiosis induced by a Western diet in mice.\nAbstract: Western-style diets promote obesity, gut dysbiosis, and metabolic dysfunction-associated steatotic liver disease (MASLD). In this study, glucoraphenin (GRE), the major glucosinolate in radish (Raphanus sativus L.) greens and sprouts, was evaluated for its effects on Western diet (WD)-induced metabolic derangements and gut dysfunction in mice. Intaking of 1 mg/kg body weight of GRE with WD for 8 weeks caused significant reductions in adipogenesis indicators such as body weight gains, adipocyte hypertrophy, and serum leptin level. This result was further proved by significant changes in lipogenesis and lipolysis-related protein expressions in adipocyte. Administration of GRE also suppressed development of MASLD, which was observed through reductions in serum ALT and AST and suppressions the expression of FAS, SREBP1, mTOR, SCD1, ACC, and ChREBP in liver tissues. GRE administration effectively prevented the decrease in the gut microbial richness and diversity caused by WD and recovered serum branched-chain amino acids and microbiota-derived purine metabolites (inosine and hypoxanthine).

Fermentation has re-emerged as a versatile processing approach because it can improve flavor and texture while remaining compatible with clean-label food design. Yet the effects of fermentation designed for alternative proteins on host physiology remain largely unexplored. This chapter examines how fermentation modifies plant- and fungal-protein foods at multiple levels and how these changes may translate into health-relevant outcomes. After outlining the major chemical and physical transformations induced by fermentation, the chapter moves beyond the traditional focus on nutrients and bioactive metabolites to consider how fermentation-driven changes in flavor and food structure influence gastrointestinal signaling and digestion. Particular attention is given to how in situ production of exopolysaccharides (EPS) during fermentation reshapes matrix organization and governs the delivery of food components along the gastrointestinal tract, where they can be utilized by the host or serve as substrates for gut microbes in complex trophic chains. Accordingly, the gut microbiome provides a key interface for these processes by integrating both chemical and physical cues from foods after ingestion, while also mediating how these cues translate into physiological responses, thereby serving as a composite readout of food properties and host physiology.

In 964 women, we measured markers of gut epithelial dysfunction (fatty acid binding protein 2, FABP2) and gut microbial antigen translocation (soluble CD14, sCD14) using sera collected before, during and after the MT. Multivariable mixed effects regressions fit piece-wise linear models to repeated FABP2 or sCD14 measures relative to time from final menstrual period (FMP).

FABP2 and sCD14 peaked 6 and 6.5 years post-FMP, respectively; subsequent levels remained stable.

Although cigarette smoke-induced oxidative stress has long been recognized as the predominant pathogenic driver, conventional inflammatory theories fail to fully account for the sustained inflammatory state that persists even after smoking cessation. Accumulating evidence indicates that COPD is governed by a metabolite-centered epigenetic regulatory network. Intracellular metabolic intermediates function not only as substrates for energy metabolism, but also as signaling molecules that directly modulate chromatin architecture and transcriptional programs. In this context, metabolic reprogramming emerges as a pivotal determinant of immune cell fate and inflammatory memory formation. This review systematically summarizes recent research advances in the \"metabolite-redox-epigenetics\" axis in COPD. We specifically discuss histone lactylation as a glycolysis-dependent inflammatory amplification mechanism and propose that histone succinylation represents a redox-sensitive epigenetic mechanism linked to mitochondrial dysfunction, bridging tricarboxylic acid (TCA) cycle dysregulation and persistent immune activation. We further integrate acetylation, crotonylation, β-hydroxybutyrylation, DNA methylation, and RNA m6A modification to construct a unified immunometabolic regulatory network. We propose that COPD is essentially a metabolically imprinted inflammatory memory disease, whose core mechanism resides in the chronic oxidative stress-triggered persistent remodeling of chromatin accessibility, which stably enforces pathogenic immune phenotypes. Targeting metabolite-driven epigenetic remodeling may offer novel therapeutic strategies to reverse chronic inflammatory memory and restore immune homeostasis. Recent evidence further suggests that cGAS-STING-mediated mitochondrial DNA sensing, inflammasome-dependent pyroptosis, gut-lung axis-derived metabolites, and AMPK/SIRT1/PGC-1α signaling may provide additional links between metabolic stress, epithelial injury, and immune dysfunction."},{"quote":"Integrating microbiome research into oncology presents novel opportunities for advancing personalized cancer prevention, diagnosis, and therapy.","source_id":"42435167","status":"PASS","error":"","abstract_text":"ID: 42435167\nTitle: Metabolism-Driven Modulation by the Human Microbiota: Implications for Cancer Therapy and Emerging Strategies.\nAbstract: The human microbiome plays a pivotal role in cancer development, progression, and therapeutic response.

UHPLC-OE-MS was employed for comprehensive metabolic profiling of the serum samples.

Subsequently, based on the coefficient of variation of ADG (CV = 65.6%), an extreme phenotype sampling (EPS) strategy was applied to select 39 individuals with extreme growth phenotypes for subsequent metabolomic, microbiome, and integrated mGWAS analyses.The results showed that ADG approximately followed a normal distribution across the 123 goats. GWAS identified 22 loci significantly associated with ADG, mapping to genes including DLK1, NCAPG2, LCORL, CNTNAP2, and SLC8A1, which are involved in pathways related to skeletal muscle development, cell cycle regulation, ion transport, and immune function. Metabolomic profiling detected 1,589 putative metabolites, revealing differential enrichment of lipid, amino acid, and bile acid metabolic pathways between fast- and slow-growing goats.

Here, middle cerebral artery occlusion was performed to stratify mice into ischemic stroke-sensitive (SEN: reaching humane endpoints within day 1) and ischemic stroke-resistant (RES: surviving to day 7) groups based on post-stroke survival. SEN mice exhibited more severe brain injury than RES mice, accompanied by increased systemic inflammation and elevated intestinal permeability.

However, the mechanisms underlying aging-related anemia, especially epigenetic dysregulation in hematopoietic stem and progenitor cells (HSPCs), remain incompletely understood. Although the gut microbiota is critical for hematopoiesis, its specific contribution to aging-related erythropoiesis impairment remains unclear. Here, we reveal that aging markedly activates phenylalanine metabolism and elevates plasma phenylacetic acid (PAA) levels in both humans and mice. We identify Odoribacter splanchnicus (O.splanchnicus) as a key gut symbiont whose abundance is significantly increased in aged mice and which directly drives PAA production from phenylalanine via the oxoacid:ferredoxin oxidoreductase (OFOR) superfamily encoded by porA,nifJ, and iorA/iorB. Rifaximin treatment selectively reduces O.splanchnicus and plasma PAA, thereby alleviating aging-related anemia. Mechanistically, PAA promotes a novel post-translational modification (PTMs) termed histone lysine phenylacetylation (Kpa) through the acetyltransferases HBO1. Elevated histone Kpa increases chromatin accessibility at the GATA2 promoter, disrupts the GATA switch, and blocks erythroid differentiation of HSPCs. In vivo, supplementation with sodium phenylacetate (NaPA) exacerbates anemia in microbiota-depleted mice, whereas the HBO1 inhibitor WM-3835 restores erythropoiesis by reversing histone Kpa and normalizing the GATA switch. Furthermore, dietary phenylalanine restriction lowers circulating PAA and effectively ameliorates aging-related anemia in both naturally aged mice and O.splanchnicus-colonized mice. These findings provide the first evidence that gut microbiota-derived PAA plays a critical role in the development of aging-related erythropoiesis impairment and offer multiple translatable strategies for treating this condition."},{"quote":"Supplementation with MI ameliorated neural damage, cerebral edema, and neuronal loss in an intake dose-responsive manner, enhanced intestinal barrier integrity","source_id":"42435878","status":"PASS","error":"","abstract_text":"ID: 42435878\nTitle: Muribaculaceae regulate β-muricholic acid to target S1PR2 signaling and reduce neurological injury in intracerebral hemorrhage.\nAbstract: Intestinal flora imbalance after intracerebral hemorrhage (ICH) aggravates neuroinflammation and secondary brain injury through the gut-brain axis, although the specific mechanism remains unclear.

A mouse ICH model was constructed by collagenase induction to evaluate the changes in gut microbiota diversity and metabolites. After intervention with Muribaculum intestinale (MI), neurological function was assessed by behavioral tests, and pathological changes of brain tissue were analyzed by Hematoxylin-Eosin and Nissl staining. Subsequently, intestinal barrier function, inflammatory factors, and total bile acid (TBA) levels were examined in ICH mice. In addition, cell viability, apoptosis, oxidative stress, inflammatory factors, and β-MA levels were analyzed in the heme-induced SH-SY5Y cell model. Molecular docking and drug affinity responsiveness target stability (DARTS) were used to analyze the interaction between β-MA and S1PR2. Intervention with a S1PR2 agonist (CYM-5520) was used to further verify the mechanism. Altered gut microbiota composition, elevated lipopolysaccharide levels, reduced expression of tight junction proteins, inflammatory activation, and disrupted bile acid metabolism were observed in ICH mice. Supplementation with MI ameliorated neural damage, cerebral edema, and neuronal loss in an intake dose-responsive manner, enhanced intestinal barrier integrity, and increased TBA levels. As a primary bile acid, β-MA directly mitigated hemin-induced oxidative stress and inflammation in neural cells.

Treatment strategies targeting liver-centric receptors, specifically the Farnesoid X Receptor (FXR), demonstrate a bidirectional capacity to attenuate hepatic steatosis and inflammation while concurrently restoring intestinal homeostasis. This synthesis investigates whether clinical and pharmacological interventions for fatty liver disease effectively reverse intestinal barrier dysfunction.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe pathophysiology of MASLD involves complex multi-organ communication, where hepatocyte lipotoxicity and altered bile acid (BA) signaling exacerbate systemic metabolic dysfunction. Therapeutic agents designed to restore hepatic health, particularly FXR agonists, act as systemic regulators. By modulating the enterohepatic circulation of bile acids, these agents alleviate metabolic hepatic stress and concomitantly improve intestinal epithelial barrier integrity. Current evidence indicates that targeting the \"synthesis-transport-signaling\" axis of bile acids is a viable strategy to reverse the systemic consequences of liver-gut crosstalk, thereby addressing the \"leaky gut\" phenotypes frequently observed in metabolic syndrome.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   FXR activation is not merely a liver-centric pathway; it acts as a central hub regulating intestinal barrier integrity and inflammation.\n*   Certain Bile Acids (BAs) modulate intestinal TGR5 signaling, providing an alternate pathway for suppressing gluconeogenic enzymes and restoring gut mucosal health.\n*   Intestinal FXR-deficiency can actually protect against steatosis while paradoxically failing to prevent MASH-associated liver inflammation, highlighting the \"therapeutic tension\" in targeting individual receptors.\n*   Dietary polysaccharides can remodel the microbiota to increase short-chain fatty acid (SCFA) production, which serves as a cross-talk mechanism to improve both liver lipid storage and intestinal mucosal barrier function.\n*   Nano-formulations of herbal extracts (e.g., nanohesperidin) provide superior FXR-activation profiles compared to non-targeted formulations, suggesting that pharmacokinetics determines the efficacy of gut-liver axis restoration.\n*   The gut-liver axis is susceptible to antibiotic-induced dysbiosis, which can undermine the efficacy of liver-directed therapies by collapsing the microbial ecosystem responsible for metabolite production.\n*   Metabolic Dysfunction-Associated Fatty Liver Disease (MAFLD) progression involves a heterogeneous continuum of microbial remodeling that must be addressed alongside host-centric pharmacological intervention to prevent progression to hepatocellular carcinoma.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

(RRT) pomace is rich in insoluble dietary fiber (IDF) and polyphenols, but free polyphenols are susceptible to premature loss during digestion. This study constructed an IDF-polyphenol complex (IDF-PP) from RRT pomace via non-covalent adsorption and evaluated its gastrointestinal fate and in vitro colonic fermentation behavior. IDF-PP reduced premature phenolic loss during simulated upper gastrointestinal digestion and enabled a more gradual release during fermentation. Structural analyses showed fermentation-induced remodeling, generating a porous residual matrix while retaining part of the polysaccharide framework. Compared with free polyphenols and IDF, IDF-PP increased short-chain fatty acid production, especially butyrate, and was associated with higher relative abundance of Prevotella-centered Bacteroidetes taxa and Faecalibacterium, together with lower relative abundance of Proteobacteria. Fermentation products also showed enhanced antioxidant and α-glucosidase inhibitory activities. These findings suggest that RRT pomace-derived IDF-PP is a promising fermentation-responsive functional ingredient with potential to modulate gut microbial fermentation.\n\nID: 42436215\nTitle: Prebiotic and postbiotic synergy alleviates age-related dysbiosis and inflammation in mice.\nAbstract: Advances in medicine and veterinary medicine extend the lifespan of humans and companion animals. Interest in nutritional strategies to support healthy aging consequently increases. In this study, the effect of 11% scFOS+ supplementation (a blend of short-chain fructo-oligosaccharides and yeast-derived postbiotics) in 18-month-old mice was evaluated, compared with aged or adult mice of 9 weeks old on a control diet. Bodyweight and food intake were monitored throughout the 56-day study. Faecal samples were collected on days 0, 28, and 56, and caecal samples at the end of the study (day 56), for microbiota analysis. Immune markers, including cytokine production in tissues and blood and toll-like receptor (TLR) expression, were analysed at day 56. The results showed that scFOS+ supplementation reduced the abundance of potentially pathogenic bacterial species and enhanced the growth of beneficial genera like Allobaculum and Bifidobacterium, aligning the microbiota profile of aged mice more closely with that of adult mice. The pro- and anti-inflammatory balance was maintained in supplemented old mice, and their TLR expression patterns resembled those observed in adults. In conclusion, combining prebiotics and postbiotics modulates immune responses in aged mice, restoring adult-like levels through gut microbiota changes and suggesting potential for promoting healthy aging in companion animals.\n\nID: 42436184\nTitle: Advances in synbiotics and synbiotic functional foods in type 2 diabetes mellitus treatment.\nAbstract: The increasing incidence of type 2 diabetes mellitus (T2DM) globally necessitates alternative therapeutic strategies. Evidence suggests that intestinal microbiota significantly influences T2DM development, leading to the proposal of probiotics as potential treatments. However, challenges such as strain selectivity and low survival rates limit probiotics' effectiveness. Combining probiotics with prebiotics, known as synbiotics, offers a promising approach for managing T2DM. The development of synbiotic-based functional foods also provides effective interventions for T2DM. This article synthesizes the recent advancements of synbiotics and synbiotic functional foods in managing T2DM, covering 40 studies, of which 29 studies employed synbiotics, and 11 studies employed synbiotic functional foods. In the 21 human studies, 17 focused on T2DM treatment and another 4 on the prevention of prediabetes from developing to T2DM. As for probiotics, 20 studies used single-strain probiotics, while others employed multiple strains, with 5 focusing on the synbiotics combined with hypoglycemic substances. Overall, synbiotics and synbiotic functional foods offer therapeutic benefits by reducing inflammation and oxidative stress, regulating gut microbiota, enhancing short-chain fatty acids, and improving intestinal barrier function. Further research is crucial to determine optimal formulations, dosages, and long-term safety, along with developing new synbiotic functional foods for effective diabetes interventions.\n\nID: 42436181\nTitle: Protein-rich food matrices from alternative and conventional sources differentially shape gut microbiota, metabolic function, and muscle protein synthesis.\nAbstract: The functional consequences of consuming conventional and alternative protein rich food matrices remain poorly understood. This study characterized diverse protein rich food matrices and investigated their effect on gut microbiota, muscle protein synthesis, and host metabolic function in rats. Arthropods and lentils contained chitin, resistant starch, polyphenols, and antioxidant activity, whereas egg and picanha were enriched in cholesterol and precursors of trimethylamine N-oxide (TMAO). Lentils and crickets consumption resulted in the lowest fat mass gain, glucose area under the curve and serum lipopolysaccharide (LPS) concentration and lentils the highest fecal butyrate. Gut microbiota alpha diversity was similar among rats fed casein, cricket, acocil, and beef diets, whereas diets containing higher amounts and different types of fat, including egg, picanha, and chinicuil, reduced alpha diversity. Cricket consumption increased the abundance of Faecalibacterium, whereas lentil consumption promoted Bifidobacterium. Rats fed picanha or egg exhibited the highest serum LPS concentrations, while acocil and beef induced the greatest stimulation of muscle protein synthesis followed by cricket, egg, and lentil diets. Biological effects of dietary protein depend on the entire food matrix rather than content alone and cricket and lentil matrices emerge as sustainable protein sources.\n\nID: 42436017\nTitle: Harnessing microbial modulators to mitigate antibiotic-induced gut dysbiosis: from phytochemicals to faecal microbiota transplantation.\nAbstract: Antibiotics remain indispensable for the management of infectious diseases; however, their use inevitably perturbs the gut microbiota. Advances in metagenomics and multiomics approaches have demonstrated that antibiotic exposure profoundly disrupts microbial diversity and community structure, leading to the depletion of key commensals, the expansion of opportunistic pathogens, metabolic dysfunction, and the emergence of antimicrobial resistance. These alterations are increasingly associated with a broad spectrum of dysbiosis-related diseases (DRDs), encompassing metabolic, neuropsychiatric, and immune-mediated disorders. To mitigate or reverse antibiotic-induced microbial imbalances, various microbiota-targeted interventions have emerged as promising alternatives or complementary approaches. These include dietary phytochemicals (such as polyphenols, alkaloids, and organosulfur compounds), probiotics, prebiotics, synbiotics, postbiotics, bacteriophage therapy, and faecal microbiota transplantation (FMT). Evidence from in vitro and animal studies has provided mechanistic insights into how these interventions modulate microbial composition and function; however, clinical evidence varies across intervention type. This review summarizes the composition and functional roles of the gut microbiota, outlines the consequences of antibiotic exposure, and provides an overview of the underlying mechanisms, recent evidence, and potential applications of microbiota-targeted interventions in preserving intestinal homeostasis. This review aims to provide a theoretical basis and reference framework for the development of safer and more effective alternatives or adjuncts to antibiotic therapy.\n\nID: 42435313\nTitle: Haematococcus pluvialis peptides ameliorated cyclophosphamide-induced immunodeficiency in mice by regulating intestinal barrier function.\nAbstract: Immunodeficiency is a pathological state characterized by impaired functional integrity of the immune system, which contributes to the development of various diseases. Natural bioactive peptides are a promising option for improving immune function. This study examined the therapeutic effects and underlying mechanisms of Haematococcus pluvialis peptides (HPP) against CTX-induced immunodeficiency in mice. The results demonstrated that HPP increased bodyweight, immune organ indices, and blood cell count - white blood cells (WBC), red blood cells (RBC), platelets (PLT), hemoglobin (HGB), lymphocytes (Lym), and granulocytes (Gran), as well as serum cytokine levels (interferon-gamma (IFN-γ), interleukin-2 (IL-2), and immunoglobulin A (IgA) - in immunodeficient mice. Haematococcus pluvialis peptides improved the villus length and crypt depth of the small intestine and increased intestinal levels of superoxide dismutase (SOD), glutathione peroxidase (GSH-PX), and secretory immunoglobulin A (SIgA). Colonic levels of tight junction proteins - zonula occludens-1 (ZO-1) and occludin - were up-regulated. Fecal microbiota analysis suggested that HPP promoted the enrichment of beneficial bacterial genera (Ligilactobacillus, norank_f_Muribaculaceae, Alistipes) and suppressed pathogenic bacteria (Escherichia-Shigella and Klebsiella). Gut microbial metabolites analysis showed that HPP altered various fecal metabolites involved in lipids and lipid-like molecules, organoheterocyclic compounds, phenylpropanoids and polyketides, as well as organic acids and their derivatives. Fecal microbiota transplantation (FMT) experiments also validated the decisive role of gut microbiota in the immunomodulatory function of HPP. These results offer novel insights into the protective efficacy and underlying mechanisms of HPP for alleviating immunodeficiency, establishing a robust theoretical basis for its application as a promising immunomodulatory agent. © 2026 Society of Chemical Industry.\n\nID: 42435168\nTitle: Gut-Liver Microbiome and Tumor Microenvironment in Metabolic Dysfunction-Associated Steatotic Liver Disease.\nAbstract: Hepatocellular carcinoma (HCC), the dominant form of primary liver cancer associated with cirrhosis, has been increasing in prevalence in the US and globally. Metabolic dysfunction-associated steatotic liver disease (MASLD), which is linked to the obesity pandemic and growing prevalence of metabolic disorders, has played a major role in this worrisome trend. Notably, up to 50% of MASLD-associated HCC develop in the noncirrhotic liver, suggesting different mechanisms of carcinogenesis as compared to HCC associated with other chronic liver diseases and potentially resulting in delays in diagnosis. Unfortunately, HCC has an unfavorable prognosis once advanced, and systemic therapies used in the management of advanced HCC have limited efficacy and considerable toxicity. More insight into HCC pathophysiology is therefore urgently needed to improve both preventive and therapeutic strategies. The gut-liver axis, and specifically the gut microbiome, appears to play a major role in the development and progression of HCC. MASLD is associated with dysbiosis, and HCC is a serious outcome of a dysfunctional relationship between the liver and the gut microbiome. Microbial-derived metabolites and cell wall components, which reach the liver via the portal and biliary circulation, may have direct oncogenic effects or activate pathways of cell proliferation, inflammation, and immunosuppression, thus altering the liver tumor microenvironment. In addition, the recent discovery of the intratumoral microbiome offers novel opportunities to learn about the host-microbiome relationship, hepatocarcinogenesis, and tumor surveillance. Further insight into the dysfunctional gut-liver axis and immuno-oncology-microbiome axis in MASLD promises to advance strategies for HCC prevention and treatment.\n\nID: 42434798\nTitle: The use of antibiotic, probiotic, and FMT in modulating Immunotherapy Efficacy and Survival: a systematic review and meta-analysis of clinical outcomes.\nAbstract: Immune checkpoint inhibitors (ICIs) have been one of the important therapeutic approaches for patients with advanced malignancies; nevertheless, their clinical efficacy remains limited in many patients. Recently, the contribution of intestinal microbiota to improved antitumor immune responses has gradually been recognized. A comprehensive literature search was conducted in PubMed, Embase, and the Cochrane Library to identify relevant studies published up to June 15, 2026. We evaluated the influence of microbiota interventions with respect to efficacy and survival in cancer patients receiving ICIs from three perspectives: antibiotics, probiotics, as well as fecal microbiota transplantation (FMT). The main endpoint was objective response rate (ORR), and secondary endpoints were overall survival (OS) and progression-free survival (PFS). The final analysis comprised 106 studies and categorized them into three groups: antibiotics (76 studies), probiotics (15 studies), and FMT (15 studies). Antibiotic use was correlated with compromised immunotherapy efficacy and unfavorable survival outcomes. In particular, antibiotics exposure was linked to a reduced ORR (Odds Ratio, OR = 0.60, 95% Confidence Interval, CI = 0.46-0.77, p < 0.001), shorter OS (Hazard Ratio, HR = 1.56, 95% CI = 1.44-1.69, p < 0.001), and shorter PFS (HR = 1.50, 95% CI = 1.32-1.70, p < 0.001). In contrast, probiotics showed a supportive and positive effect on immunotherapy outcomes, with improved ORR (OR = 1.95, 95% CI = 1.46- 2.62, p < 0.001) and better OS (HR = 0.56, 95% CI = 0.41- 0.78, p < 0.001) and PFS (HR = 0.53, 95% CI = 0.38-0.74, p < 0.001). FMT combined with immunotherapy achieved a favorable ORR of 0.30 (95% CI = 0.16-0.45, p < 0.001). This meta-analysis synthesized evidence from studies on antibiotics, probiotics, and FMT use, suggesting gut microbiota offering potential approaches to enhance immunotherapy treatment effectiveness and clinical efficacy in individuals with advanced-stage solid cancers.\n\nID: 42434548\nTitle: Abdominal massage alleviates IBS-D by modulating the gut microbiota and suppressing the LPS/TLR4/NF-κB/MLCK pathway.\nAbstract: Diarrhea-predominant irritable bowel syndrome (IBS-D) is a common functional gastrointestinal disorder with complex and incompletely understood pathophysiology. This study aimed to investigate the therapeutic effects and underlying mechanisms of abdominal massage on diarrhea-predominant IBS-D using a rat model. IBS-D was induced in Sprague-Dawley rats through a combination of maternal separation and chronic stress. The experimental interventions consisted of abdominal massage and fecal microbiota transplantation (FMT) using donor microbiota obtained from IBS-D + abdominal massage rats. Assessments included fecal moisture content (FMC), Bristol stool scores, visceral hypersensitivity, intestinal motility, open field test, gut microbiota, short-chain fatty acids (SCFAs), inflammatory markers (LPS, TLR4/MyD88/NF-κB pathway), and intestinal barrier integrity (TEM, tight junction proteins, FITC-dextran permeability). Abdominal massage significantly improved diarrheal symptoms, visceral hypersensitivity, gastrointestinal motility, and anxiety-like behaviors in IBS-D rats. It restored gut microbiota diversity, reduced SCFA levels, and suppressed the TLR4/MyD88/NF-κB pathway, leading to decreased pro-inflammatory cytokines and LPS levels. FMT replicated these effects, suggesting the role of gut microbiota modulation. Moreover, abdominal massage also ameliorated barrier dysfunction in IBS-D rats by restoring ultrastructure, modulating MLCK and junctional proteins, and reducing macromolecular permeability. Abdominal massage alleviates IBS-D symptoms by modulating gut microbiota, inhibiting the TLR4/MyD88/NF-κB/MLCK signaling pathway, reducing inflammation, and restoring intestinal barrier function. These findings support its potential as a non-invasive therapeutic strategy for IBS-D.\n\nID: 42433272\nTitle: The role of the microbiota in hematological malignancies: A narrative review of mechanisms and therapeutic potential.\nAbstract: The human microbiota, particularly the gut microbiome, plays a central role in maintaining immune homeostasis, regulating hematopoiesis, and modulating host metabolism through bioactive metabolites such as short-chain fatty acids (SCFAs), bile acids, and tryptophan-derived compounds. Disruption of this microbial ecosystem (dysbiosis) has emerged as a key contributor to the development and progression of hematological malignancies (HMs), including acute and chronic leukemias, lymphomas, and multiple myeloma. This narrative review synthesizes recent evidence (2022-2025) on the complex bidirectional interactions between the microbiota and HMs, highlighting their biological and clinical significance. Current evidence indicates that the microbiota influences hematological malignancies through multiple interconnected mechanisms, including immune regulation, inflammatory signaling, maintenance of hematopoietic homeostasis, and microbial metabolite-mediated modulation of the tumor microenvironment. Dysbiosis has been associated with disease progression, increased susceptibility to infections, impaired treatment tolerance, and inferior clinical outcomes. Conversely, chemotherapy, broad-spectrum antibiotics, and hematopoietic stem cell transplantation profoundly reshape microbial communities, further exacerbating dysbiosis and contributing to complications such as graft-versus-host disease following allogeneic transplantation. Emerging microbiota-targeted interventions, including dietary modulation, probiotics, prebiotics, and fecal microbiota transplantation, show promise for restoring microbial homeostasis and improving therapeutic outcomes. Furthermore, microbiome-derived biomarkers are increasingly being investigated for predicting treatment response, relapse risk, and immunotherapy efficacy. Despite these advances, important challenges remain, particularly in establishing causal relationships, standardizing microbiome profiling, and validating clinical applications through well-designed prospective and randomized studies. Overall, the accumulating evidence supports the microbiota as a critical determinant of hematological cancer biology and treatment response. Integrating microbiome-based diagnostics and therapeutic strategies into precision hematology may offer new opportunities to improve patient management and long-term clinical outcomes.\n\nID: 42433126\nTitle: A Modular Liver-Microbial Microfluidic Platform to Evaluate Therapeutic and Adverse Effects of Microbial Metabolites.\nAbstract: Gut microbial metabolites, particularly short-chain fatty acids (SCFAs) like butyrate, play a significant role in modulating non-alcoholic fatty liver disease (NAFLD). While animal studies show that butyrate-producing microbes can improve liver function, full recovery is hindered by unintended side effects from commensal bacteria. These underlying biomolecular mechanisms remain elusive, due to the lack of in vitro coculture models capable of systematically examine both the therapeutic benefits of engineered microbial metabolites and their potential adverse impacts. To address this, we developed a modular microfluidic platform to study the effects of live microbial metabolites on hepatic steatosis and liver function. We created a microfluidic-based hepatic steatosis model integrated with a compartmentalized microbial module, facilitating the study of how metabolites produced by live microbes affected the liver model. We compared the effects of synthetic SCFA supplementation with those of coculturing with a control and butyrate-producing E. coli Nissle 1917 (EcN) strains on hepatic steatosis. Our findings showed that live microbial coculture did not phenocopy exogenous SCFA treatment. While both treatments reduced steatotic lipid accumulation, live microbes induced inflammatory and hepatic metabolic changes, suggesting contributions from additional microbial factors, emphasizing the need to thoroughly assess side effects in liver disease treatment.\n\nID: 42432847\nTitle: Effects of Acute Ruminal Acidosis on Rumen Epithelial Integrity, Permeability, and Transcriptome in Sheep.\nAbstract: Acute ruminal acidosis (ARA) is characterized by a significant decline in rumen pH, a significant increase in lipopolysaccharide (LPS) and lactic acids, and a significant decrease in volatile fatty acids (VFA) in rumen fluid. The objectives of this study were to characterize the structural, functional, and molecular changes in rumen epithelium during ARA and to determine which rumen fluid components drive these changes. Twelve sheep were used in this study, of which six were fasted overnight followed by ad libitum access to a concentrate diet to develop ARA, and six sheep were fed alfalfa hay to serve as controls. Forty-eight hours later, all sheep were euthanized, and rumen tissue samples were collected for histological analysis, ex vivo permeability assessment, and RNA sequencing. Primary rumen epithelial cells were isolated from additional healthy sheep for in vitro experiments. Statistical analyses were performed using Student's t-test or one-way ANOVA followed by Tukey's HSD test. The rumen epithelium from acidotic sheep showed increased permeability and histological damage, including parakeratosis, epithelial lifting, and partial loss of the stratum corneum layer of the rumen epithelium, compared to that from control sheep (P < 0.05). RNA sequencing identified 2,563 differentially expressed genes (adjusted P < 0.05 and |log2 fold change| ≥ 1) in the rumen epithelium between acidotic and control sheep. Functional enrichment analyses revealed that genes upregulated in acidotic rumen were enriched in ribosome biogenesis, translation, and keratinization, whereas genes downregulated in acidotic rumen were associated with immune response, cell adhesion, and tight junction (P < 0.05). Examples of differentially expressed genes were CLDN1, OCLN, and TJP1 (tight-junction genes); MRPL23, NOP53, and RPS6 (ribosome and translation genes); and IL17B, TLR4, and MYD88 (immune genes). To determine which rumen fluid changes in acidotic versus control sheep are directly responsible for differential expression of these genes in the rumen, primary ovine rumen epithelial cells were treated with pH, lipopolysaccharides, L-lactic acid, D-lactic acid, and butyrate at levels approximating those in acidotic or control sheep. Low medium pH (5.0) decreased OCLN and MYD88 expression while increasing TJP1, MRPL23, and TLR4 expression compared to normal medium pH (7.4) (P < 0.05). LPS, L-lactate, and D-lactate at concentrations found in rumen fluid of acidotic sheep did not affect the expression of these genes compared to those found in control sheep (P < 0.05). Butyrate at concentration found in rumen fluid of control sheep increased (P < 0.05) CLDN1, OCLN, and RPS6 expression while having no effect on the other genes, compared with concentration found in rumen fluid of acidotic sheep. In conclusion, ARA is associated with marked structural, functional, and transcriptomic changes in rumen epithelium, and these changes may be partially driven by reduced rumen pH and reduced butyrate concentration in rumen fluid. Acute ruminal acidosis is a digestive disorder that affects agriculturally important ruminants such as cattle and sheep. During acute ruminal acidosis, the rumen pH decreases sharply, and potentially harmful compounds such as lipopolysaccharide and D-lactic acid build up in the rumen. In this study, we determined the changes that occur in the rumen tissue during acute ruminal acidosis and identified the rumen fluid components responsible for these changes. We found that the rumen epithelium of sheep with acute ruminal acidosis was leaky and that its surface was damaged. We also found significant gene expression differences in the rumen tissue between acidotic and normal sheep. These gene expression differences suggest barrier dysfunction and immune suppression in the rumen of acidotic sheep. Data of in vitro experiments using primary sheep rumen epithelial cells suggest that significantly lowered pH and significantly reduced butyrate production impair rumen epithelial integrity, barrier function, and local immune response, which may in turn contribute to systemic problems such as systemic inflammation in affected animals.\n\nID: 42432702\nTitle: Distinct SCFA profiles drive contrasting impacts of whole versus refined grains on metabolic health and body composition beyond inflammation in older adults: a secondary analysis of a randomized controlled trial.\nAbstract: Although whole grains (WG) are widely recommended for health, the divergent impacts of WG versus refined grains (RG) on metabolism, body composition, and inflammation, mediated by distinct short-chain fatty acid (SCFA) profiles, require deeper investigation in older adults. This secondary analysis of a randomized controlled trial aimed to elucidate these differential effects and explore the specific mediating roles of SCFA changes. While maintaining their habitual non-staple food intake, 102 participants were randomly assigned to either the WG or RG groups and provided with standardized ingredients for staple food preparation. Fecal SCFAs, blood pressure, blood glucose, renal function markers, body composition, and systemic immune-inflammation markers were assessed at baseline and post-intervention, with further exploration of inter-variable correlations and mediation pathways among these factors. WG favored butyrate percentage, while RG increased acetate proportion. WG consumption improved post-prandial diastolic blood pressure (DBP), an effect not observed in the RG group, and yielded a significantly greater reduction in serum creatinine. Conversely, RG intake resulted in statistically significant short-term body composition changes, reducing fat mass and increasing lean mass. Mediation analysis revealed that changes in butyrate and acetate acted as suppressors in the pathways linking dietary grain type to post-prandial DBP and blood urea nitrogen changes, respectively. Systemic immune-inflammation markers did not differ between groups. In our study, we observed that WG and RG consumption elicited distinct SCFA profiles and divergent metabolic and body composition responses in middle-aged and older adults. WG intake preferentially benefited blood pressure and renal function, potentially through SCFA-related pathways, while RG intake unexpectedly improved short-term body composition. These findings highlight the complexity of grain-microbiota-host interactions and suggest that the grain consumed substantially influences metabolic outcomes through SCFA-mediated mechanisms.

While fecal microbiota transplantation (FMT) shows promise as a MetS therapy, existing meta-analyses have reported conflicting results and focused mainly on glycemic parameters, leaving its impact on lipid metabolism largely unexplored. This meta-analysis systematically assessed the influence of allogenic FMT on lipid parameters in patients with MetS, unraveling its potential as an innovative therapeutic modality for this population. A meta-analysis was performed to explore the impact of allogenic FMT on lipid parameters (triglycerides, total cholesterol [TCHO], high-density lipoprotein cholesterol [HDL-C] and low-density lipoprotein cholesterol [LDL-C]) in patients with MetS. Terms regarding FMT and MetS were searched in PubMed/Medline, EMBASE, Web of Science, the Cochrane Library, and Scopus from the inception of the databases until 31 August 2023. Nine randomized controlled trials (RCTs) were included and subgroup analyses according to follow-up durations were performed. This study was registered in PROSPERO (ID CRD42023389890). A total of 248 patients were included. Patients undergoing allogenic FMT manifested significantly lower TG level compared with control group (receiving placebo or autologous FMT, pooled MD -0.15 [95% CI: -0.29, -0.01]), as well as higher HDL-C level (MD 0.07 [95% CI: 0.02, 0.12]). Subgroup analysis confirmed that these effects were significant at 4 to 6 weeks post-FMT (TG: MD -0.16, 95% CI: -0.32, -0.01; HDL-C: MD 0.08, 95% CI: 0.02, 0.15). No significant difference was observed between allogenic FMT and control group concerning TCHO and LDL-C levels regardless of lengths of follow-up. In subgroup analysis, the results regarding TG and HDL-C remained consistent in the subgroup with 4 to 6 weeks of follow-up. An overall reduction in TG level and elevation in HDL-C level was observed in patients with MetS receiving allogenic FMT. A potential optimal timeframe for FMT efficacy manifestation might be 4 to 6 weeks after first administration.

Proanthocyanidins (PC), a class of dietary polyphenols, have been suggested to modulate the gut-brain axis. Here, we investigated the mechanisms by which PC alleviate cognitive deficits in a thyroxine-induced accelerated aging-like mouse model. PC supplementation significantly improved spatial learning and memory, as assessed by the Morris water maze. These effects were accompanied by modulation of gut microbiota composition and altered fecal short-chain fatty acids (SCFAs), particularly butyrate and propionate. PC also improved intestinal barrier function, increased colonic tryptophan hydroxylase 1 (TPH1) expression, and regulated 5-hydroxytryptophan (5-HTP)/serotonin (5-HT)-related pathways. In parallel, hippocampal neuroinflammatory responses were attenuated. Collectively, these findings suggest that the neuroprotective effects of PC are associated with a gut microbiota-SCFAs-5-HTP/5-HT axis. This study highlights the potential of dietary proanthocyanidins as a nutritional strategy for mitigating cognitive impairment under thyroxine-induced accelerated aging-like conditions.\n\nID: 42431700\nTitle: Hyperammonaemic encephalopathy presenting as a stroke mimic with normal liver function tests.\nAbstract: Hyperammonaemia is a potentially reversible cause of encephalopathy that can mimic focal neurological syndromes. A man in his 60s presented with light-headedness, vomiting and abdominal pain. He developed acute aphasia and right-sided weakness within 24 hours, and although serial CT brain imaging and CT angiography were normal, conscious level deteriorated rapidly, such that he required intubation and mechanical ventilation. MRI brain demonstrated symmetrical basal ganglia T1 hyperintensity. Metabolic investigation identified hyperammonaemia (147 µmol/L). He was treated with lactulose, rifaximin and continuous veno-venous haemofiltration with biochemical and neurological improvement and resolution of neurological deficits. In the absence of overt liver failure, small bowel bacterial overgrowth was considered the most likely cause although potential additional contributory factors were also identified. This case highlights the need to measure ammonia early in otherwise unexplained encephalopathy, even when liver function tests are normal.\n\nID: 42431620\nTitle: Prebiotics and asthma: current insights and future directions from a bibliometric analysis.\nAbstract: Prebiotics have gained attention as a microbiome-modulating strategy in asthma because they may influence immune regulation through the gut-lung axis. However, evidence on prebiotics and asthma remains distributed across allergy, immunology, nutrition, microbiology, and respiratory medicine. This study aimed to map global research trends, influential contributors, and thematic development in prebiotics-asthma research using bibliometric analysis. This bibliometric study analyzed English-language articles and reviews indexed in Scopus. Prebiotic-related and synbiotic-related terms were combined using OR and then linked with asthma-related terms using AND. Eligible records were screened for relevance to prebiotics and asthma. Bibliometric analyses and visualizations were performed using Biblioshiny and VOSviewer to evaluate publication output, leading contributors, citation impact, keyword co-occurrence, and temporal research trends. A total of 296 publications from 166 sources were included. The earliest eligible publication was published in 2002. Annual scientific production increased over time, with an annual growth rate of 13.66% and the highest output in 2024. Review articles outnumbered original articles. The United States was the leading contributor, followed by Australia, the Netherlands, Italy, and China. Keyword analysis identified three major domains: mechanistic and immunologic studies, early-life allergy prevention, and microbiota-focused modulation. Trend analysis showed a shift toward gut microbiome, short-chain fatty acids, immune dysregulation, and gut-lung axis. Prebiotics-asthma research is a relatively recent but steadily growing field with increasing emphasis on microbiome-mediated and mechanistic pathways. However, asthma-specific translational evidence remains limited, supporting the need for standardized clinical studies and integrative multi-omic approaches. Los prebióticos han recibido atención como estrategia de modulación del microbioma en pacientes con asma, debido a su influencia en la regulación inmunitaria a través del eje intestino-pulmón. Sin embargo, la evidencia relacionada con los prebióticos y el asma permanece distribuida entre diferentes disciplinas. Mapear las tendencias globales de investigación, influencias de los contribuyentes y desarrollo temático en la investigación acerca de los prebióticos y el asma mediante un análisis bibliométrico. Se analizaron artículos y revisiones en inglés indexados en Scopus. Los términos relacionados con prebióticos y simbióticos se combinaron mediante OR y luego se vincularon con términos asociados con asma mediante AND. Los registros elegibles se evaluaron por su relevancia para prebióticos y asma. El análisis bibliométrico se llevó a cabo con Biblioshiny y VOSviewer para evaluar la producción científica, influencia de los contribuyentes, efecto de la citación, co-ocurrencia de palabras clave y tendencias temporales. Se incluyeron 296 publicaciones de 166 fuentes. La primera publicación elegible apareció en 2002. La producción anual aumentó con el tiempo, con una tasa de crecimiento de 13.66%, y la mayor cantidad de publicaciones se registró en 2024. Las revisiones superaron a los artículos originales. Estados Unidos fue el principal país contribuyente, seguido de Australia, Países Bajos, Italia y China. El análisis de palabras clave identificó tres dominios: 1) estudios mecanísticos e inmunológicos, 2) prevención temprana de alergias y 3) modulación centrada en la microbiota. El análisis de tendencias mostró un cambio en el microbioma intestinal, los ácidos grasos de cadena corta, la desregulación inmunitaria y el eje intestino-pulmón. La investigación acerca de prebióticos y asma es reciente, pero creciente. La evidencia traslacional específica para asma sigue siendo limitada, por lo que se requieren estudios clínicos estandarizados y enfoques multiómicos integrativos.\n\nID: 42431475\nTitle: Harnessing the Microbiome for Head and Neck Cancer Therapy: From Mechanistic Insights to Translational Opportunities.\nAbstract: The human microbiome, particularly the diverse microbial communities in the oral cavity and gut, plays a critical role in the pathogenesis, progression, and treatment response of head and neck squamous cell carcinoma (HNSCC). Emerging evidence indicates that specific microbial communities can bidirectionally modulate cancer therapeutic modalities. Moreover, interventions such as probiotics, prebiotics, and fecal microbiome transplantation have the potential to improve treatment efficacy and alleviate adverse effects. This review outlines the mechanisms underlying oral and gut microbiota in HNSCC development and progression, focusing on their bidirectional regulation of efficacy and toxicity across standard treatments, including surgery, radiotherapy, chemotherapy, targeted therapy, and immunotherapy. We emphasize that microbial signatures not only serve as predictive biomarkers and therapeutic targets but also constitute a fundamental component of personalized oncology in HNSCC, providing a comprehensive framework for integrating microbiota-based strategies into clinical practice.\n\nID: 42431043\nTitle: Microstructure-driven oxidative stability and gut microbiota modulation of flaxseed oil Nano-capsules: A freeze-drying versus vacuum-drying comparative study.\nAbstract: This study compared freeze-drying (FD) and vacuum-drying (VD) for preparing flaxseed oil nano-capsules (FO NC). Structurally, FD formed a porous matrix, while VD caused flattening and aggregation. Although both methods achieved effective encapsulation, FD-FO NC better preserved heat-sensitive components, exhibited lower moisture content (1.39%) and hygroscopicity (1.89%). During 28-day storage, FD-FO NC showed superior stability: controlled reduction in psize (669.03 to 322.28 nm), higher retention of encapsulation efficiency (90.44% to 65.61% in 3 weeks), and lower peroxide values (<0.7 g/100 g). In vitro fermentation indicated FD-FO NC more effectively modulated gut microbiota, enriching beneficial bacteria and increasing SCFAs production (acetate: 20.07 mmol/L; butyrate: 1.90 mmol/L). The novelty of this work lies in its systematic comparative evaluation of FD and VD for nano-capsules, linking their microstructure and oxidative stability to in vitro gut microbiota modulation and SCFAs production, thereby providing new insights for the design of functionally enhanced delivery systems.\n\nID: 42430494\nTitle: p38 MAP kinase senses short-chain fatty acids to attenuate Toll-like receptor signaling and intestinal inflammation.\nAbstract: Toll-like receptor (TLR) signaling is critical for innate immune system. However, whether it is directly modulated by microbiota-derived metabolites remains unclear. Here, we show that the short-chain fatty acids (SCFAs) propionate and butyrate suppress TLR signaling by directly binding p38α MAP kinase, promoting its interaction with TAB1, thereby activating p38α via autophosphorylation. Activated p38α then phosphorylates TRAF3 at serine 85, inhibiting K63-linked polyubiquitylation of TRAF3 and disrupting TBK1-IRF3 activation, leading to reduced macrophage activation and intestinal inflammation. In ulcerative colitis patients, fecal levels of propionate and butyrate positively correlate with p38α activity and TRAF3 S85 phosphorylation, but inversely correlate with TBK1 activation, and cytokine levels. Notably, oral administration of propionate in three patients with ulcerative colitis markedly improved intestinal inflammation and clinical symptoms. These findings reveal p38α as a direct sensor for microbiota-derived SCFAs that suppress TLR signaling through nonmetabolic functions of propionate and butyrate, providing the first clinical evidence that propionate supplementation represents a practical dietary strategy for ulcerative colitis management.\n\nID: 42430365\nTitle: Gut Microbiota Drives Aging-related Erythropoiesis Impairment via Phenylacetic Acid-induced Histone Phenylacetylation.\nAbstract: Anemia, the most prevalent hematologic disorder in older adults, imposes a significant burden of cardiovascular events, cognitive decline, and mortality. However, the mechanisms underlying aging-related anemia, especially epigenetic dysregulation in hematopoietic stem and progenitor cells (HSPCs), remain incompletely understood. Although the gut microbiota is critical for hematopoiesis, its specific contribution to aging-related erythropoiesis impairment remains unclear. Here, we reveal that aging markedly activates phenylalanine metabolism and elevates plasma phenylacetic acid (PAA) levels in both humans and mice. We identify Odoribacter splanchnicus (O.splanchnicus) as a key gut symbiont whose abundance is significantly increased in aged mice and which directly drives PAA production from phenylalanine via the oxoacid:ferredoxin oxidoreductase (OFOR) superfamily encoded by porA,nifJ, and iorA/iorB. Rifaximin treatment selectively reduces O.splanchnicus and plasma PAA, thereby alleviating aging-related anemia. Mechanistically, PAA promotes a novel post-translational modification (PTMs) termed histone lysine phenylacetylation (Kpa) through the acetyltransferases HBO1. Elevated histone Kpa increases chromatin accessibility at the GATA2 promoter, disrupts the GATA switch, and blocks erythroid differentiation of HSPCs. In vivo, supplementation with sodium phenylacetate (NaPA) exacerbates anemia in microbiota-depleted mice, whereas the HBO1 inhibitor WM-3835 restores erythropoiesis by reversing histone Kpa and normalizing the GATA switch. Furthermore, dietary phenylalanine restriction lowers circulating PAA and effectively ameliorates aging-related anemia in both naturally aged mice and O.splanchnicus-colonized mice. These findings provide the first evidence that gut microbiota-derived PAA plays a critical role in the development of aging-related erythropoiesis impairment and offer multiple translatable strategies for treating this condition.\n\nID: 42430127\nTitle: Oral Lysozyme Attenuates Neuroinflammation and Brain Injury After Traumatic Brain Injury Through Gut Microbiota-Dependent Reprogramming of Tryptophan Metabolism.\nAbstract: Traumatic brain injury (TBI) induces secondary neuroinflammation and gut dysbiosis. This study investigated whether oral lysozyme confers neuroprotection after TBI through gut microbiota-dependent metabolic reprogramming of tryptophan metabolism. In a severe TBI mouse model, neurological function, neuroinflammation, intestinal barrier integrity, and systemic immune homeostasis were assessed following oral lysozyme administration. Fecal untargeted metabolomics, antibiotic-mediated microbiota depletion, and fecal microbiota transplantation (FMT) were used to explore microbiota involvement. Cerebrospinal fluid (CSF) from 10 matched pairs of patients with severe TBI was analyzed for tryptophan pathway metabolites by liquid chromatography-mass spectrometry. Lysozyme improved neurological outcomes, attenuated neuronal apoptosis and neuroinflammation, and restored peripheral CD4+/CD8+ T cell homeostasis. Metabolomics revealed enrichment of fecal tryptophan metabolites (indole-3-carboxaldehyde, indolelactic acid, kynurenic acid [KYNA]) and a shift in cerebral kynurenine metabolism toward the KYNA branch. These associations were abolished by microbiota depletion and reproduced by FMT. Favorable clinical outcomes were associated with higher CSF KYNA and an elevated KYNA/QA ratio. Oral lysozyme was associated with attenuated TBI-induced neuroinflammation and brain injury, potentially through gut microbiota-dependent tryptophan metabolism reprogramming. Concordance between preclinical and clinical metabolomic data supports lysozyme as a candidate microbiota-targeted therapeutic strategy. The KYNA/QA ratio warrants further validation as a prognostic indicator in larger, longitudinal cohorts.\n\nID: 42430016\nTitle: Therapeutic Delivery of Bone Marrow Mesenchymal Stem Cell-Derived Exosomal miR-143-3p Inhibits Myocardial and Systemic Inflammation and Attenuates Sepsis-Related Myocardial Injury.\nAbstract: Sepsis-related myocardial injury (SRMI) is a major contributor to mortality in septic patients, driven by uncontrolled inflammation and macrophage dysregulation. Bone marrow mesenchymal stem cell-derived exosomes (BMSC-Exos) possess immunomodulatory properties, but their cardioprotective mechanisms remain unclear. Here, we investigated whether BMSC-Exos deliver microRNA-143-3p (miR-143-3p) to reprogram macrophages and attenuate SRMI. Exosomes were isolated from murine bone marrow mesenchymal stem cells and characterized by electron microscopy, nanoparticle tracking analysis, and immunoblotting. In lipopolysaccharide-stimulated macrophages, BMSC-Exos promoted a shift from pro-inflammatory M1 to reparative M2 polarization, and reduced pro-inflammatory cytokine secretion. In a mouse model of endotoxemia, BMSC-Exo administration improved seven-day survival, preserved cardiac function, decreased circulating myocardial injury markers, and increased the proportion of cardiac M2 macrophages. MicroRNA sequencing identified miR-143-3p as highly enriched in BMSC-Exos but downregulated in circulating exosomes from septic mice. Delivery of miR-143-3p mimics recapitulated the protective effects of BMSC-Exos, while inhibition of miR-143-3p exacerbated injury. Mechanistically, miR-143-3p directly targeted Toll-like receptor 4 (TLR4) and suppressed the downstream myeloid differentiation primary response 88/nuclear factor-κB (MyD88/NF-κB) signaling pathway. Furthermore, TLR4 knockdown phenocopied the anti-inflammatory and M2-polarizing effects of miR-143-3p. These findings indicate that BMSC-Exos attenuate SRMI by transferring miR-143-3p to macrophages, where it inhibits TLR4/MyD88/NF-κB signaling and promotes M2 polarization, highlighting a potential therapeutic strategy for septic cardiac injury.\n\nID: 42429666\nTitle: Sialidase inhibitor modulates gut microbiota and enhances mucosal protection in the treatment of ulcerative colitis.\nAbstract: Ulcerative colitis (UC) is characterized by mucosal barrier erosion, a process exacerbated by bacterial sialidases. We investigated the therapeutic efficacy of the sialidase inhibitor (SI) in UC. In a pilot randomized clinical trial, SI intervention significantly improved clinical symptoms and endoscopic outcomes in mild-to-moderate UC patients. This improvement correlated with an enrichment of butyrate-producing taxa and beneficial metabolic pathways. In a dextran sulfate sodium-induced colitis mouse model, SI attenuated inflammation and restored mucus layer integrity, accompanied by increased expression of Muc2 and Tff3. Crucially, unlike broad-spectrum antibiotics, SI preserved microbial community resilience while specifically enriching beneficial mucolytic commensals, Akkermansia muciniphila and Bacteroides acidifaciens. These findings identify SI as a promising therapeutic strategy that targets sialidase activity to reinforce the mucosal barrier and restore gut homeostasis.IMPORTANCEThe gut microbiota plays a pivotal role in maintaining mucosal integrity and intestinal homeostasis; however, dysbiosis-driven mucus layer degradation remains a hallmark of ulcerative colitis (UC). Current interventions like antibiotics often disrupt microbial diversity, exacerbating dysbiosis and failing to address mucosal thinning, which is a critical factor in UC progression. Developing strategies to reinforce the mucus barrier without compromising microbial balance is urgently needed, but such approaches remain underexplored. Our study demonstrates that sialidase inhibitors (SIs) uniquely preserve mucosal thickness by curbing microbial mucin degradation while selectively enriching beneficial taxa and butyrate-producing bacteria. Unlike antibiotics, SIs enhance mucosal protection without destabilizing microbial communities, offering a dual-action therapeutic strategy. This work bridges a critical knowledge gap, providing evidence for microbiota-targeted therapies that synergistically restore mucosal health and microbial ecology in UC.CLINICAL TRIALSThis study was registered with the Chinese Clinial Trial Registry as ChiCTR2000028767.\n\nID: 42429658\nTitle: Effects of gut microbiota on the susceptibility of ischemic stroke in mice.\nAbstract: Ischemic stroke is a highly prevalent disease with limited therapeutic options, and emerging evidence suggests that the gut microbiota influences stroke pathophysiology. However, whether the gut microbiota affects individual susceptibility to ischemic stroke remains unclear. Here, middle cerebral artery occlusion was performed to stratify mice into ischemic stroke-sensitive (SEN: reaching humane endpoints within day 1) and ischemic stroke-resistant (RES: surviving to day 7) groups based on post-stroke survival. SEN mice exhibited more severe brain injury than RES mice, accompanied by increased systemic inflammation and elevated intestinal permeability. Fecal microbiota from SEN or RES donors was transplanted into antibiotic-treated recipients. Mice receiving SEN microbiota developed significantly worse outcomes compared with those receiving RES microbiota. Multi-omic analyses of cecal contents, including 16S rRNA gene sequencing and liquid chromatography-mass spectrometry/mass spectrometry-based untargeted metabolomics, identified reduced butyrate-producing bacteria and altered glutathione metabolism as potential contributors to stroke susceptibility. Collectively, these findings demonstrate that gut microbiota and microbial metabolites modulate susceptibility to ischemic stroke. The role of the gut microbiota in determining susceptibility to ischemic stroke has remained poorly defined. This study demonstrates that microbiota dysbiosis and metabolite alterations functionally increase vulnerability to stroke injury, highlighting the gut microbiome as a potential target for risk stratification and preventive interventions. Modulating the gut microbiota may therefore represent a novel strategy for reducing stroke susceptibility.\n\nID: 42429614\nTitle: Higher abundance of Faecalibacterium prausnitzii in the gut microbiome is associated with a lower risk of sepsis development among 6,372 individuals followed for 20 years.\nAbstract: The human gut microbiome has been suggested to be linked with the risk of developing sepsis, a life-threatening medical emergency. However, it remains unclear whether the gut microbiome is an independent predictor of long-term sepsis risk in the general adult population. Here, we investigated for the first time the prospective association between the gut microbiome and incident sepsis in the general population. The study sample (FINRISK) consisted of 6,372 individuals who underwent fecal sampling in 2002 and were followed for incident sepsis. We used multivariable-adjusted models to study the associations of microbial alpha-diversity, beta-diversity, taxa, butyrate producers, and predicted pathways with incident sepsis. Two hundred and forty participants developed sepsis over a follow-up of 19.8 years. A 1-SD increase in Faecalibacterium prausnitzii_C_71351 abundance was associated with 21% (95% CI, 10%-30%; FDR = 0.03) lower risk of sepsis. Higher abundances of six other species were associated with higher sepsis risk (FDR < 0.05 for all). Five of these species were positively associated with C-reactive protein. The species-sepsis associations were consistent across various subgroups. Moreover, in an independent validation cohort of 4,248 individuals, we found a similar association between Faecalibacterium and a lower risk of future sepsis. Additionally, overall pathways related to carbohydrate degradation, energy production, and sulfur metabolism were positively linked to incident sepsis. We did not detect any associations of alpha-diversity, beta-diversity, or butyrate producers with incident sepsis. Future studies should investigate the causality of these associations and the mechanisms by which the identified species may influence sepsis development.IMPORTANCEPrevious cross-sectional and case-control studies have linked changes in the gut microbiome with the occurrence of sepsis. However, the relationship between the gut microbiome and the risk of incident sepsis in the general adult population remains unexplored. Here, we found clear evidence on the association of gut microbiome species with incident sepsis in a large population cohort. In particular, we provided an in-depth analysis of the negative link between F. prausnitzii and sepsis risk, which was robust across independent cohorts. This finding supports a potential protective role of F. prausnitzii, but further experimental investigation is required. We also show that six species, including Clostridium symbiosum-a causative agent of bacteremia/sepsis in few cases-are positively linked to incident sepsis. Most of these species were also positively linked to an inflammatory marker. Our research provides the groundwork for future experimental analysis of the detected associations to understand their role in infection.\n\nID: 42429613\nTitle: Gut Microbiota, Immunity, and Metabolism in the Progression From Chronic Liver Disease to Hepatocellular Carcinoma.\nAbstract: The progression from chronic liver injury to hepatocellular carcinoma (HCC) should be viewed as a heterogeneous continuum of immune, metabolic, fibrotic, and microbial remodeling rather than as a single linear route. Although this review uses the MASLD-MASH-fibrosis/cirrhosis-HCC sequence as a mechanistically informative model, the gut-liver-immune framework is also relevant, with important etiology-specific differences, to alcohol-associated liver disease (ALD), chronic hepatitis B virus (HBV) infection, chronic hepatitis C virus (HCV) infection, and mixed-etiology liver disease. Across these contexts, hepatocyte lipotoxicity or viral/alcohol-induced injury, mitochondrial stress, endotoxemia, altered bile-acid signaling, fibrotic remodeling, and immune exhaustion progressively reshape the hepatic microenvironment toward tumor-permissive inflammation and immune escape. We integrate transcriptomic, single-cell, spatial, microbial, and metabolomic evidence to define stage- and etiology-dependent immunometabolic states. Particular emphasis is placed on microbial metabolites, including short-chain fatty acids, secondary bile acids, and tryptophan-derived indoles, which engage host receptors such as FFAR2/3, GPR109A, FXR, TGR5, AhR, and PXR to influence lipid metabolism, epithelial barrier integrity, cytokine programs, epigenetic remodeling, and antitumor surveillance. We further discuss how sex, baseline microbiome composition, hepatic zonation, and preclinical model selection influence disease trajectories and therapeutic responses. By focusing on the gut microbiota-metabolism-immunity axis, this review provides a systems-level framework for biomarker discovery, risk stratification, precision nutrition, and rational combination therapies. Targeting the coordinated interplay among diet, microbiota, metabolism, immunity, and the hepatic spatial niche may help intercept chronic liver disease before malignant transformation and improve therapeutic responses in established HCC.\n\nID: 42429253\nTitle: Association between Dietary Intake of Live Microbes and Asthma Risk in Children and Adolescents Aged 6-15 Years: A Cross-sectional analysis.\nAbstract: Emerging evidence implicates gut dysbiosis in asthma pathogenesis via the gut-lung axis. This cross-sectional study aimed to examine the associations between dietary live microbes intake and asthma risk among US children and adolescents aged 6 to 15 years. We analyzed data from the 2007-2018 National Health and Nutrition Examination Survey. Dietary live microbes intake was evaluated using the Sanders method and categorized into low, medium, and high categories. Asthma status was determined by self-report. Multivariable binary logistic regression was used to evaluate the association between dietary live microbe intake and asthma prevalence. Of the 7,547 participants (mean age 10.8 years; 51.9% male) included, the overall prevalence of asthma was 11.3%. Compared with the low dietary live microbes intake group, the multivariate-adjusted odds ratio (95% confidence intervals) for asthma in the medium and high intake groups were 0.75 (0.63-0.88) and 0.52 (0.41-0.64), respectively (P for trend < 0.001). Subgroup analyses suggested trends toward stronger protective associations among girls (P for interaction = 0.073) and those exposed to household smoking (P for interaction = 0.070). Sensitivity analyses using propensity score matching and additional adjustment for prebiotics, probiotics, and synbiotics yielded results consistent with the primary analysis. Higher dietary live microbe intake was significantly associated with lower asthma prevalence in US children and adolescents aged 6-15 years. These findings support additional investigation of dietary live microbe consumption as a modifiable factor for asthma prevention in this age group.\n\nID: 42429144\nTitle: Gut dysbiosis‑derived butyrate loss predicts feeding intolerance: Multiomics evidence guiding nurse‑driven microbiota‑supportive interventions (Review).\nAbstract: Feeding intolerance (FI) is a common and debilitating challenge among critically ill patients that is linked to a pathway involving the collapse of the gut microbial ecology. The present review synthesizes multiomics evidence supporting a framework whereby critical illness‑associated gut dysbiosis results in a functional deficit of a microbially derived short‑chain fatty acid butyrate, a pivotal metabolite involved in maintaining intestinal barrier integrity, immuneoregulation and gastrointestinal motility. The loss of butyrate‑producing bacteria and their genetic pathways is strongly correlated with FI and may represent a contributory pathogenic mechanism. Key butyrate‑producing organisms diminished during this process include Faecalibacterium prausnitzii and Roseburia spp. Building upon this mechanistic framework, a pragmatic, nurse‑driven intervention model aimed at preserving and restoring microbial health in critically ill patients was proposed. This model is founded on four principal strategies: Minimizing iatrogenic harm (such as antibiotic/proton pump inhibitor stewardship), targeted microbiota nourishment (pre/synbiotics), cautious microbial restoration (probiotics/fecal microbiota transplantation) and innovative monitoring approaches. By integrating principles of microbial ecology with clinical nursing science, the present review provides a framework for developing nurse‑driven protocols designed to address the underlying pathophysiology of FI and improve patient outcomes.\n\nID: 42428532\nTitle: Ameliorative Effects of Newly Developed Citrus Hybrid \"Mubong\" Peel Extract on Experimental Colitis and Gut Microbiota Dysbiosis.\nAbstract: \"Mubong,\" a newly developed citrus hybrid, is recognized for its unique flavor profile, yet its chemical composition and therapeutic potential remain unexplored. In the present work, we profiled the phytochemical content and antioxidant capacities of \"Mubong\" flesh and peel, then evaluated the anti-inflammatory effects of the \"Mubong\" Peel Extract (MPE) using in vitro (LPS-stimulated RAW 264.7 cells) and in vivo (DSS-induced colitis) models, coupled with microbiota analysis. In vitro anti-inflammatory activity was studied by measuring nitric oxide (NO) production and NF-κB signaling in RAW-Blue cells. In vivo, ICR mice were administered MPE (400 mg/kg) orally during DSS-induced colitis. Disease severity was evaluated through the Disease Activity Index (DAI), colon length, and histological analysis. To characterize microbial and metabolic shifts, we integrated 16S rRNA hypervariable region sequencing with targeted quantification of short-chain fatty acids (SCFAs). MPE was found to be rich in naringin (2730.66 ± 93.90 mg/100 g), neohesperidin (1493.85 ± 82.67 mg/100 g), and d-limonene (69.06%). In vitro, MPE (200-400 μg/mL) significantly inhibited NO production and suppressed NF-κB-dependent transcriptional activity. In mice, MPE treatment was associated with the attenuation of weight loss, reduction of DAI scores, and the mitigation of colon shortening. These clinical improvements were also coincided with a reduction in pro-inflammatory cytokines, specifically TNF-α (~80 to ~52 pg/mL) and IL-6 (~30 to ~3 pg/mL), and restoration of the SCFAs, propionic acid (~35% to ~80%) and butyric acid (~30% to ~50%). Microbiota analysis revealed that MPE treatment correlated with alterations in the gut landscape, specifically the enrichment of obligate anaerobes such as Lachnoclostridium and Acetatifactor. Furthermore, these microbial changes paralleled a recovery trend in short-chain fatty acids (butyrate and propionate) otherwise depleted by DSS. Our findings suggest that MPE exerts anti-inflammatory activity, likely through the modulation of NF-κB/AP-1-dependent transcriptional activity and preservation of gut microbial homeostasis. These preclinical findings suggest that \"Mubong\" warrants further investigation as a potential functional food candidate for the management of ulcerative colitis and related inflammatory disorders.\n\nID: 42428317\nTitle: Herbal medicines modulate gut microbiota in metabolic diseases: a review.\nAbstract: Metabolic diseases-including obesity, type 2 diabetes mellitus (T2DM), and non-alcoholic fatty liver disease (NAFLD)-affect over 1 billion individuals globally and are characterized by insulin resistance, chronic inflammation, and gut microbiota dysbiosis. Herbal medicines offer multi-component therapeutic potential through microbiota modulation, but mechanistic insights remain fragmented. This review synthesizes recent advances in herbal medicine-mediated gut microbiota regulation in metabolic diseases and delineates underlying molecular mechanisms. A comprehensive literature search was conducted across PubMed and Web of Science. Search strategies employed MeSH terms and free-text keywords encompassing herbal medicines, gut microbiota, and metabolic diseases. Two authors performed study selection and data extraction. Evidence synthesis was structured according to intervention type and metabolic disease category. Herbal polysaccharides and other compounds consistently increased beneficial bacteria and promoted short-chain fatty acids (SCFAs) production, improving intestinal barrier integrity via ZO-1/Occludin upregulation and attenuating TLR4/NF-κB-mediated inflammation. Herbal formulations exerted synergistic effects by remodeling microbial community structure, correcting SCFA/bile acid imbalances, and activating IRS1/PI3K/AKT insulin signaling. Notably, Lactobacillus and Akkermansia emerged as recurrent beneficial targets across multiple herbal interventions. However, evidence is predominantly preclinical, and translational validity to humans requires further validation. Herbal medicines ameliorate metabolic diseases through multi-target gut microbiota modulation, involving SCFA production, bile acid metabolism, and inflammatory pathway attenuation. These mechanistic insights support the development of microbiota-targeted herbal therapeutics, though clinical translation necessitates standardized formulations and rigorous human trials.\n\nID: 42428310\nTitle: Advances in understanding intestinal microbiota mechanisms and intervention strategies for anxiety, depression, sleep disorders, and constipation.\nAbstract: Anxiety, depressive symptoms, sleep disorders, and chronic constipation frequently co-occur and collectively impose a substantial clinical burden. Although these conditions may involve partially overlapping neural, endocrine, immune, and metabolic processes, their shared pathophysiological basis has not been fully established. This narrative review examines the potential role of the microbiota-gut-brain axis in linking affective symptoms, sleep disturbances, and chronic constipation. Evidence from human observational studies, Mendelian randomization analyses, animal models, and preliminary interventional studies suggests that alterations in gut microbial composition and function may contribute to these clinical associations through microbial metabolites, immune signaling, neuroendocrine regulation, and neural pathways. The review also summarizes microbiota-targeted interventions, including probiotics, prebiotics, dietary modification, and fecal microbiota transplantation. However, substantial heterogeneity in study populations, microbial findings, experimental methods, and intervention protocols limits causal interpretation and clinical generalization. A more rigorous distinction among associative, mechanistic, genetic, and interventional evidence is therefore required when evaluating the therapeutic potential of microbiota-based strategies.\n\nID: 42428309\nTitle: Translating priority effects and niche engineering into rational microbiome therapeutics across the gut-lung axis.\nAbstract: The homeostasis of the human microbiome relies on \"colonization resistance\" governed by complex ecological rules. However, severe perturbations such as broad-spectrum antibiotics can dismantle this defense, shifting the microbial community into a \"dysbiotic trap\" driven by pathogen niche construction-an alternative stable state that is notoriously difficult to spontaneously reverse. This ecological mechanism explains the frequent failure of empirical therapies like fecal microbiota transplantation (FMT) and blind probiotic supplementation. Crucially, local ecological collapse triggers systemic cascades via the \"gut-lung axis.\" The depletion of core gut metabolites, such as short-chain fatty acids, impairs the metabolic reprogramming and antimicrobial capacity of distal alveolar macrophages. This cascade drastically increases host susceptibility to respiratory infections. To break this clinical deadlock, microbiome medicine must transition from \"empirical transplantation\" to \"rational microbiome engineering.\" This review systematically outlines the core pillars of this translational framework: achieving \"precision niche clearing\" via targeted bacteriophages; capturing optimal intervention windows to harness \"priority effects\"; and ultimately engrafting \"synthetic microbial consortia\" (SMCs) rationally designed upon metabolic cross-feeding principles. This strategy offers a promising avenue to durably shatter the dysbiotic deadlock and restore host immune homeostasis across the gut and systemic levels.\n\nID: 42427432\nTitle: Toward a Dual-Axis Model of Microbiome Modulation in Cancer Immunotherapy: Pathobiont Elimination and Functional Ecosystem Restoration.\nAbstract: The gut microbiome is increasingly recognized as a modulator of cancer immunotherapy efficacy, including responses to immune checkpoint inhibitors (ICIs) and chimeric antigen receptor T-cell (CAR-T) therapy. Recent clinical trials of microbiome-targeted interventions such as fecal microbiome transplantation (FMT) and live biotherapeutic products (LBPs) suggest the potential to enhance antitumor immunity and improve clinical outcomes. Yet responses remain heterogeneous and are not fully explained by engraftment of donor taxa alone. We integrate evidence from interventional trials, observational cohort studies, and principles from gut microbial ecology to develop a model hypothesis on how microbiome-targeted therapies may shape response to immunotherapy, with potential to inform future trial design, analyses, and interpretation. Drawing on the available evidence, we propose that therapeutic perturbation of the gut microbiome may augment immunotherapy efficacy through two parallel axes: (1) elimination of immunosuppressive pathobionts that restrain CD8+ T-cell activation and promote myeloid-mediated immunosuppression, and (2) functional restoration of the gut ecosystem through engraftment of taxa that provide metabolites, structural cues, and immunoregulatory signals required for effective antitumor immunity. The success of both axes appears to depend on ecological processes governed by predator-prey dynamics, including colonization resistance, resilience of the resident microbiota, and the ability of administered organisms to displace entrenched dysbiotic communities. This ecological lens may help to explain discrepancies across trial designs, donor types, and intervention modalities, and suggests that complete donor engraftment is neither necessary nor sufficient for clinical benefit. A dual-mechanism model of pathobiont elimination and functional microbial restoration may help explain microbiome-mediated enhancement of cancer immunotherapy, highlighting a balanced immune permissive gut ecosystem as a key determinant of therapeutic success.\n\nID: 42427207\nTitle: Cyclocarya paliurus Polysaccharides Attenuate High-Fat Diet-Induced Metabolic Dysfunction via Gut Microbiota Remodeling.\nAbstract: Alterations in gut microbiota composition are closely associated with obesity and metabolic disorders. Cyclocarya paliurus polysaccharides (CCPP) have been shown to improve lipid metabolism and modulate the gut microbiota; however, mechanistic evidence remains limited and may vary depending on preparation methods. This study investigated whether a crude polysaccharide-enriched Cyclocarya paliurus preparation alleviates high-fat diet-induced metabolic dysfunction and is associated with gut microbiota remodeling. Male C57BL/6 J mice were randomized into three groups: normal diet (ND), high-fat diet (HFD), and HFD supplemented with CCPP for 12 weeks. Serum metabolic parameters were measured; intestinal inflammatory cytokine transcripts were assessed by qRT-PCR; and cecal microbiota composition was analyzed by 16S rRNA gene sequencing. Additionally, fecal microbiota transplantation (FMT) was performed by transferring microbiota from CCPP-treated donors to antibiotic-pretreated HFD-induced recipients for 8 weeks. CCPP attenuated HFD-induced body weight gain and reduced subcutaneous and visceral adipose tissue mass. CCPP significantly improved serum total cholesterol and low-density lipoprotein cholesterol (LDL-C) and reduced fasting glucose. Cecal 16S rRNA gene profiling showed that CCPP reshaped the gut dysbiosis associated with a HFD and enriched microbial taxa that are commonly linked to carbohydrate fermentation. These taxa specifically include Lachnospiraceae-related microbial taxa and Ileibacterium. Importantly, FMT from CCPP-treated donors recapitulated these metabolic improvements, confirming that the benefits of CCPP were microbiota-dependent. CCPP mitigates obesity and metabolic dysfunction by remodeling the gut microbiota, particularly by enriching short-chain fatty acid-producing taxa. These findings highlight CCPP as a potential microbiota-targeted therapeutic agent for metabolic disorders.\n\nID: 42426988\nTitle: Genetic Toolbox Expansion Enables Constitutively Fluorescent Lacticaseibacillus rhamnosus for Functional Microbiome Research.\nAbstract: Lacticaseibacillus rhamnosus strains are widely recognized for their probiotic potential and relevance in urogenital and gut health. However, their genetic tractability and genetic tools remain limited, hindering functional microbiome research and synthetic biology applications. In this study, we expanded the genetic toolbox for the widely used probiotic strains, L. rhamnosus GR-1 and L. rhamnosus GG, by implementing direct plasmid cloning and testing of a set of genetic elements earlier validated in Lactiplantibacillus plantarum. Among five constitutive promoters (PtlpA, Ptec, Pcpg, P48 and P23), PtlpA showed strong promoter activity in L. rhamnosus GR-1. We further characterized this promoter's functionality by incorporating a repressor and assessing its native thermo-responsiveness and stability over time, enhancing its potential for industrial applications. Using these tools, we engineered L. rhamnosus GR-1 with constitutive fluorescence of mCherry, mScarlet3 and sfGFP. The functionality of these fluorescent L. rhamnosus GR-1 strains was shown in a proof-of-concept growth competition experiment with a fluorescent pathogenic Staphylococcus aureus strain. These constitutively fluorescent L. rhamnosus strains, along with the expanded genetic toolkit, offer valuable resources for studying functional properties, such as adhesion, microbe-microbe and host-microbe interactions, and advancing Lactobacillaceae as a chassis for synthetic biology.\n\nID: 42426884\nTitle: Multi-omics and functional validation reveal that Methanobrevibacter-derived L-3-aminoisobutyrate alleviates subclinical mastitis in dairy goats via the HSPA1B-p65 signaling pathway.\nAbstract: Subclinical mastitis (SCM) is prevalent in dairy livestock and compromises milk quality and lactation performance. Although often attributed to bacterial infection, many cases lack identifiable pathogens, suggesting alternative mechanisms. While evidence supports a gut-mammary gland axis, the microbial drivers and microbiota-derived metabolites linking gut dysbiosis to SCM remain unclear. Here, we aimed to identify SCM-associated gut microbial markers, prioritize candidate therapeutic metabolites and define the underlying mechanism. Based on differences in somatic cell count (SCC) and inflammatory phenotypes across a cohort of 167 mid-lactation Saanen dairy goats, we selected 6 healthy and 6 SCM goats for downstream analyses. By integrating metagenomics, metabolomics, cross-species fecal microbiota transplantation (FMT) and functional validation in vitro and in vivo, we found that SCM was accompanied by reduced milk yield and heightened inflammatory signatures. Compared with the Healthy group, SCM goats exhibited marked remodelling of the gut microbiota, with enrichment of opportunistic taxa (Eubacterium and Blautia) and a pronounced depletion of archaeal Methanobrevibacter spp. Notably, FMT from SCM donors recapitulated mammary inflammatory phenotypes in mice, supporting a causal contribution of gut dysbiosis to mammary inflammation. Joint metagenomic functional profiling and metabolomics further identified the branched-chain amino-acid-derived metabolite L-3-aminoisobutyrate (BAIBA) as significantly enriched in the gut of healthy goats. Moreover, Methanobrevibacter spp. harboured key enzyme genes (vorA, vorB and vorD) implicated in BAIBA biosynthesis. In an LPS-challenged MAC-T model, BAIBA attenuated mammary epithelial inflammation by activating endoplasmic reticulum protein quality control programmes and restoring HSPA1B expression, thereby suppressing NF-κB activation and reducing pro-inflammatory cytokine production. Finally, in naturally infected goats, intramammary administration of BAIBA lowered SCC, highlighting translational potential. This study identifies BAIBA as a microbiota-derived metabolite that protects against SCM by restraining mammary inflammation via the HSPA1B-NF-κB axis, establishing a mechanistic gut-mammary link and highlighting a potential non-antibiotic intervention strategy.

A healthy gut microbiota influences and enhances the neonatal health, and aids in multidimensional development-metabolically, immunologically, neurologically, and hormonally. Several microorganisms like Lactobacillus and Bifidobacterium get transferred to the infant gut and play a key role in its colonization and programming. Administration of such microbes, or probiotics, to the mother can assist in improving the benefits imparted by breastmilk to the infant, and can also provide health benefits to the mother. In recent years, there has been a focus on related metagenomic studies and the immunological effects of individual genera have also been studied in detail. In this review, we observe the gut-mammary pathway and the different roles played by probiotics in prenatal and postnatal scenarios. We also analyze the level of evidence of potential of some promising probiotic strains in the transfer, establishment, and development of infant gut microbiota based on recently conducted studies. The analysis of recent metagenomic studies proved that strains like Bifidobacterium infantis, Lactobacillus rhamnosus, and Limosilactobacillus reuteri exibit a high level of evidence in benefitting the microbiota transfer as well as establishment, diversification, and development of the infant gut ecosystem. Hence, these strains in particular, can be given as supplements to mothers during pregnancy and lactation, in order to improve their inherent immunity and the overall health of the mother-infant dyad. With the advent of metagenomics, the roles, functions and effects of microbes in the gut-mammary pathway have been re-examined. This review, critically evaluates the recent studies related to gut-mammary pathway and the different roles played by probiotics in prenatal and postnatal scenarios with particular emphasis on the strength and quality of their evidence.\n\nID: 42425839\nTitle: Right colon volvulus causing acute bowel obtruction.\nAbstract: \n\nID: 42435958\nTitle: From gut lumen to extragut tissue: dysbiosis-induced gut bacterial translocation mediates antibiotic resistance gene enrichment in Eisenia fetida under polystyrene microplastic and roxithromycin exposure.\nAbstract: Microplastics' (MPs) capacity to sorb antibiotics in soil ecosystems poses emerging risks, yet their combined toxic effects on soil fauna remain poorly understood. Consequently, we examined the gut toxicity and antibiotic resistance genes (ARGs) of polystyrene MPs (PS-MPs) and the macrolide antibiotic roxithromycin (ROX) in Eisenia fetida. Overall, although co-exposure suppressed gut barrier gene expression (occludin and ZO-1), it did not worsen bacterial translocation (LPS and LBP) relative to single exposures, which is associated with the significant upregulation of antibacterial defense indicators (TLR and CCF), potentially enhancing bacterial clearance. Additionally, PS-MPs mediated the reduction of ROX bioaccumulation by 34.78%, which contributed to the antagonistic interactions observed across multiple indicators, including attenuated deterministic assembly of gut microbiota and ARGs under co-exposure. Beyond enriching resistant Actinobacteria (e.g., Streptomyces and Actinophytocola), ROX also enriched plastisphere-associated pathogenic taxa Escherichia and Enterococcus, as did PS-MPs. These taxa were closely implicated in gut barrier dysfunction and exhibited the strongest correlations with gut ARGs and mobile genetic elements (MGEs) profiles, particularly macrolide-lincosamide-streptogramin B (MLSB) resistance genes (mphA-01, oleC) and MGEs (intI-1(clinic), tnpA-02). Though co-exposure did not increase gut ARGs and MGEs abundance, the enrichment of gut-dominant MLSB resistance genes and MGEs extended to earthworm body tissue, notably driven by PS-MPs, while ROX increased intI-1 (clinic), the strongest contributor to overall variation. PLS-PM revealed that tissue ARGs and MGEs enrichment was associated with gut bacterial translocation driven by dysbiosis-induced activation of LPS-TLR signaling pathways, raising concerns about ARGs dissemination through earthworm-derived traditional medicine and food chains.\n\nID: 42434047\nTitle: The Plastic Within: Micro- and Nanoplastics in Human Tissues and the Nutritional Context for Exposure Mitigation.\nAbstract: Microplastics (MPs) and nanoplastics (NPs) are increasingly detected in human tissues, prompting concern about potential biological effects. Yet, for most outcomes, the literature remains dominated by detection studies and preclinical toxicology, with limited human dose-response data. We conducted a narrative review of peer-reviewed literature (2000-2025), prioritizing human biomonitoring and tissue-detection studies, observational health-outcome studies, and mechanistic evidence that plausibly links exposure to cardiometabolic, reproductive, and neuroinflammatory pathways. Certainty of evidence was appraised using GRADE principles where applicable and explicitly separated from mechanistic plausibility. MPs/NPs have been reported in blood, lung, placenta, atherosclerotic plaques, brain, liver, and testicular tissue. The most clinically salient human outcome signal to date is an association between plaque microplastics and subsequent major adverse cardiovascular events in an observational cohort (hazard ratio 4.53, 95% CI 2.00-10.27). However, polymer quantification approaches vary (particle counts vs polymer mass), contamination control is method-dependent, and inter-study comparability remains limited. The current evidence base supports aggressive exposure reduction as the most defensible \"first-line\" strategy. Nutritional approaches (dietary fiber, gut-barrier support, and microbiome modulation) are best framed as adjunctive, mechanistically plausible risk-mitigation strategies rather than proven methods to remove plastics from the body. Well-designed human trials and standardized analytical protocols are needed before clinical \"detoxification\" claims can be justified.\n\nID: 42433375\nTitle: Shared inflammatory architecture and therapeutic tensions between psoriasis and Crohn's disease.\nAbstract: Psoriasis and Crohn's disease are chronic immune-mediated inflammatory diseases affecting distinct barrier organs, yet epidemiological, genetic, transcriptomic, and therapeutic evidence supports partial immune convergence between them. This review argues that the relationship between psoriasis and Crohn's disease reflects partial immune convergence shaped by tissue context, rather than a single shared disease entity. TNF-α and IL-23-centered type 17 immunity represent the most clinically relevant shared upstream programs, whereas downstream effector pathways, especially IL-17-related responses, are shaped differently by skin and gut barrier architecture, resident immune ecology, microbial exposure, and repair demands. We discuss the gut-skin axis with caution: barrier dysfunction, dysbiosis, microbial metabolites, and immune-cell trafficking may connect skin and intestinal inflammation, but direct causal evidence in humans remains limited. TNF inhibitors, IL-12/23 blockade, and selective IL-23 inhibitors are the most plausible options for selected patients requiring treatment compatible with both skin and gut disease, whereas IL-17 blockade and paradoxical psoriasiform reactions illustrate organ-specific therapeutic tensions. Future progress will depend on patient stratification using clinical phenotypes, biomarkers, tissue profiling, and treatment history to identify patients in whom skin and intestinal inflammation are driven by overlapping immune mechanisms.\n\nID: 42431962\nTitle: Intestinal FXR deficiency uncouples steatosis protection from liver inflammation and fibrosis in MASH-diet fed mice.\nAbstract: The Farnesoid X Receptor (FXR), a nuclear bile acid (BA) receptor highly expressed in the liver and intestine, is a potential pharmacological target for Metabolic dysfunction-Associated SteatoHepatitis (MASH). While intestinal FXR inhibition reduces high-fat diet (HFD)-induced hepatic steatosis, its role in MASH progression remains unclear. This study investigates the impact of intestinal FXR-deficiency on MASH development in a diet-induced murine model. Intestinal FXR-deficient (intFXR KO) and control mice were fed a high-fat, sucrose, and cholesterol-enriched diet (HFSC) for 24 weeks. Intestinal immune phenotyping, microarray, 16 S rRNA sequencing, bile acid quantification and liver assessments (histology, biochemistry and single-cell RNA sequencing (scRNA-seq)) were performed. intFXR KO mice were protected against HFSC diet-induced obesity and hepatic steatosis but exhibited altered expression of intestinal barrier-associated genes, with increased cytotoxic CD8+ T-lymphocytes. Microbiota composition and bile acid profiles were altered, including reduced Lachnospiraceae species correlating negatively with liver hyocholic acid levels. Despite a protection against hepatic steatosis, liver inflammation and fibrosis were unchanged in intFXR KO mice. Transcriptomic and Immune cell scRNA-seq analysis revealed alteration in immune-related pathways with an increased neutrophil proportion and higher cDC1:cDC2 and CD4:CD8 T cell ratios. Thus, intestinal FXR-deficiency limits steatosis but promote a distinct hepatic immune-inflammatory response and does not prevent progression to MASH.\n\nID: 42427618\nTitle: Preserved Barrier Integrity and Altered Immune Profiles in Chronic Cannabis Users: Potential Roles of Δ9-Tetrahydrocannabinol.\nAbstract: Although cannabinoids such as delta-9-tetrahydrocannabinol (THC) are generally immunosuppressive in preclinical models, chronic cannabis use in humans is paradoxically associated with increased infection risk and systemic inflammation. In this study, we demonstrate that THC directly strengthens intestinal epithelial barrier function in vitro by increasing trans-epithelial electrical resistance in a concentration-dependent manner in Caco-2 monolayers. In a cross-sectional study of chronic cannabis users via smoking or snorting compared with non-using controls, plasma lipopolysaccharide (LPS), and microbial translocation-driven inflammatory cytokines (IL-23, MCP-1, IL-8) were significantly reduced, while some cytokines (IL-6, IL-1β, TNF-α, IL-10) remained unchanged. Concurrently, users exhibited elevated macrophage-derived chemokine (MDC) and homeostatic cytokines IL-15 and IL-21, markedly suppressed IL-7 and IL-4. Plasma IL-15 and MDC levels correlated with consumption intensity, and IL-23, IL-7, and IP-10 correlated with age of first use or during heaviest use. These findings suggest that habitual cannabis use may protect gut barrier integrity and reduce microbial translocation and associated inflammation, while simultaneously disrupting systemic immune homeostasis through selective cytokine dysregulation. This dual, dose-dependent immunomodulatory profile highlights the complex balance between potential benefits and risks in both recreational and therapeutic cannabis use.\n\nID: 42427128\nTitle: Targeting ferroptosis with chenodeoxycholic acid improves residual cardiac dysfunction after surgical ventricular reconstruction.\nAbstract: Surgical ventricular reconstruction (SVR) partially reverses left ventricular remodelling in postinfarction heart failure, yet residual cardiac dysfunction persists through unknown mechanisms. We investigated ferroptosis involvement in post-SVR pathology and explored pharmacological interventions. Myocardial infarction (MI) was induced in C57BL/6 mice followed by SVR at 4 weeks. Cardiac function was assessed by echocardiography and pressure-volume catheterization. Ferroptosis biomarkers were quantified. Connectivity Map analysis identified candidate compounds validated in Erastin-challenged AC16 cardiomyocytes and SVR mouse models. Compared with MI group, SVR improved the left ventricular end-diastolic volume index by 36.8% but showed persistent iron overload, glutathione depletion and elevated malondialdehyde. Transcriptomic analysis identified 90 ferroptosis-related differentially expressed genes following SVR. Connectivity Map prioritized three ferroptosis inhibitors, and chenodeoxycholic acid (CDCA) exhibited superior efficacy. Farnesoid X receptor (FXR) knockdown in AC16 cardiomyocytes exacerbated erastin-induced ferroptosis, while CDCA co-treatment significantly reduced erastin-induced ROS production, upregulated glutathione peroxidase 4 (GPX4) expression, and restored superoxide dismutase activity, rescued the ferroptotic phenotype and reversed associated molecular changes in FXR-knockdown cells. In SVR-treated mice, 3-week CDCA administration (50 mg·kg-1·day-1) reduced myocardial iron deposition by 14.8%, improved left ventricular ejection fraction from 23.73% to 31.61% and restored GSH/GSSG ratio from 1.645 to 1.988. CDCA up-regulated GPX4 expression by 1.573-fold compared with the vehicle group. SVR paradoxically exacerbates ferroptosis in residual myocardium through iron dysregulation and antioxidant depletion. CDCA, a primary bile acid activating FXR signalling, is a novel pharmacological strategy to mitigate post-SVR ferroptosis and improve cardiac outcomes.\n\nID: 42424917\nTitle: RGD-functionalized cannabidiol lipid nanoparticles improve brain delivery and alleviate cognitive and metabolic dysfunction via gut-brain axis modulation in an Alzheimer's disease model.\nAbstract: Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by cognitive decline and neuronal loss. Evidence links gut-brain axis dysfunction and metabolic disturbances to AD. Although cannabidiol (CBD) has neuroprotective effects, its use is limited by poor bioavailability and brain delivery. Arginylglycylaspartic acid (RGD)-functionalized, CBD-loaded lipid nanoparticles (CBD/LNP-RGD) were developed to enhance targeted delivery across the blood-brain barrier (BBB) via integrin αvβ3-mediated transcytosis. Cellular uptake and BBB permeability were evaluated in vitro. Anti-inflammatory and antioxidant effects were assessed in Aβ/LPS-induced models. In vivo efficacy was examined using cognitive-behavioral tests, including the novel object recognition and the Morris water maze. Metabolic parameters, histopathology, synaptic protein expression, and gut barrier integrity were also evaluated. CBD/LNP-RGD demonstrated a 3-fold increase in cellular uptake and a 65% enhancement in BBB transport compared to non-targeted formulations. Treatment significantly reduced pro-inflammatory cytokines (i.e., IL-6 and TNF-α, p < 0.001) and intracellular reactive oxygen species (p < 0.001). In vivo, CBD/LNP-RGD improved cognitive performance comparable to Donepezil (p < 0.001). Additionally, it normalized glycemic control, insulin resistance, and triglyceride levels without hepatic or renal toxicity. At the tissue level, CBD/LNP-RGD reduced Aβ and tau pathology, restored short-chain fatty acids, preserved hippocampal neuronal integrity, and upregulated synaptophysin and PSD-95 proteins. Enhanced intestinal barrier function was evidenced by increased expression of tight junction proteins ZO-1 and occludin. CBD/LNP-RGD represents a multifunctional nanotherapeutic platform that improves brain delivery and exerts neuroprotective, anti-inflammatory, antioxidant, and metabolic regulatory effects. Its ability to modulate both central pathology and the gut-brain axis highlights its potential as a disease-modifying strategy for Alzheimer's disease.\n\nID: 42424108\nTitle: Markers of compromised gut epithelial barrier integrity increase during the menopause transition.\nAbstract: In female murine models, one source of inflammation is a menopause-related increase in gut permeability. We examined whether the menopause transition (MT) in women is associated with an increase in markers of gut epithelial dysfunction and gut microbial product translocation, signals of compromised gut epithelial barrier integrity. In 964 women, we measured markers of gut epithelial dysfunction (fatty acid binding protein 2, FABP2) and gut microbial antigen translocation (soluble CD14, sCD14) using sera collected before, during and after the MT. Multivariable mixed effects regressions fit piece-wise linear models to repeated FABP2 or sCD14 measures relative to time from final menstrual period (FMP). Covariates were age at FMP, race/ethnicity, and BMI. FABP2 and sCD14 did not change significantly until 2.5 years pre-FMP. At that point, FABP2 began rising; sCD14 began increasing 6 months later. FABP2 and sCD14 peaked 6 and 6.5 years post-FMP, respectively; subsequent levels remained stable. During the ~9-year interval of MT-related gain in gut barrier compromise markers, annual FABP2 and sCD14 increases were 2.6% (95% CI: 1.7 to 3.4%) and 0.8% (95% CI: 0.6 to 1.1%), respectively, among white women with sample-average BMI and age at FMP. FABP2 and sCD14 change rates did not differ significantly by race/ethnicity, BMI, or age at FMP. The MT is associated with a rise in markers of compromised gut barrier integrity, suggesting that this pathway of inflammation, previously described in animal models, occurs in humans.

In this review, we explore recent progress in understanding the gut microbiota's role in liver regeneration and discuss its therapeutic potential in the context of hepatic surgery and liver transplantation. Emerging evidence shows that beneficial microbial taxa, including Akkermansia muciniphila, Bifidobacterium longum, and Parabacteroides distasonis, enhance liver regeneration by regulating short-chain fatty acid production, bile acid metabolism, and tricarboxylic acid cycle pathways, while dysbiosis and microbial translocation can impair regenerative outcomes. Key host-microbiome interactions, particularly the Farnesoid X Receptor (FXR)-Fibroblast Growth Factor 19 (FGF19) signaling axis, play a central role in protecting hepatocytes from bile acid overload and supporting regeneration, highlighting the therapeutic potential of FXR agonists, FGF19 mimetics, probiotics, dietary interventions, and metabolite supplementation. At the same time, monitoring bile acids profiles alongside gut microbiota composition may allow early detection and prevention of complications. In addition, microbial-derived markers such as the lipopolysaccharide/lipoteichoic acid ratio may serve as predictive biomarkers for post-hepatectomy liver failure. Adjunctive approaches, including vitamin D supplementation, may further support regeneration through vitamin D receptor-mediated regulation of bile acid homeostasis and cell-cycle progression. In the context of live donor liver transplantation, the detection of occult bacteremia further underscores the complexity of host-microbiome interactions and suggests that microbiological surveillance could improve postoperative management. Collectively, these findings emphasize the importance of microbiota-targeted strategies to improve hepatic regeneration, reduce postoperative complications, and optimize outcomes following liver surgery and transplantation.\n\nID: 42422874\nTitle: The role of gut microbiota dysbiosis in the pathogenesis of hyperuricemic nephropathy.\nAbstract: Hyperuricemic nephropathy (HN) is a renal complication associated with sustained hyperuricemia and urate-related renal injury. Emerging evidence suggests that gut microbiota dysbiosis may participate in HN pathogenesis by influencing uric acid metabolism, intestinal urate excretion, gut barrier integrity, microbial metabolite production, and gut-kidney immune crosstalk. However, the strength of evidence varies substantially across proposed mechanisms, with many findings derived from animal models, in vitro experiments, CKD studies, or human studies of hyperuricemia and gout rather than HN-specific clinical cohorts. This review summarizes current clinical and experimental evidence linking gut microbiota dysbiosis with HUA, gout, CKD, and HN, critically evaluates proposed mechanistic pathways, and discusses microbiota-targeted interventions including probiotics, prebiotics, dietary strategies, fecal microbiota transplantation, and metabolite-based approaches. Particular emphasis is placed on distinguishing association from causality and identifying translational gaps that should be addressed in future HN-specific studies.\n\nID: 42422752\nTitle: Shaping postoperative outcomes: microbiota-modifying dietary fiber interventions in colorectal cancer treatment.\nAbstract: The gut microbiota plays a key role in intestinal homeostasis by reinforcing the gut barrier and modulating inflammation. Gut barrier dysfunction or dysregulated inflammatory response in patients with colorectal cancer may lead to an increased risk of surgical complications associated with poor intestinal healing. Microbiota-modifying dietary interventions have the ability to shift microbial community structures and bacterial metabolite production, with profound implications for host health. This review focuses on the potential for short-term, preoperative, dietary fiber interventions in improving colorectal cancer surgical and oncological outcomes. Additionally, this review highlights important considerations for the optimization and personalization of dietary fiber interventions, notably individual- and fiber-specific microbiota responses.\n\nID: 42422741\nTitle: Akkermansia muciniphila in cardiovascular diseases: opportunities and challenges.\nAbstract: Cardiovascular disease (CVD) is one of the leading causes of death worldwide and poses a severe threat to human health. Recent years have witnessed a growing interest in how the gut microbiota regulates the cardiovascular system. Akkermansia muciniphila (A. muciniphila), a key constituent of this community, has become a focus of research on CVD prevention owing to its critical role in maintaining gut homeostasis, modulating metabolism, and regulating immunity. This review details the beneficial effects and mechanisms of action of A. muciniphila in CVD. A. muciniphila protects against conditions such as hypertension, atherosclerosis, heart failure, and abdominal aortic aneurysm by repairing the gut barrier, balancing glucose and lipid metabolism, regulating immune-inflammatory responses, and producing protective metabolites such as short-chain fatty acids. However, in pathological states, such as a damaged gut barrier or low-fiber diets, A. muciniphila can over-proliferate, accelerate mucus breakdown, and exacerbate inflammation and disease progression-revealing a \"double-edged sword\" character. Furthermore, diet, medications, and an individual's baseline gut microbiota directly modulate their abundance, underscoring the need for personalized approaches. Future studies should focus on clarifying strain differences, establishing safe dosing, and optimizing delivery systems to advance the clinical application of A. muciniphila in CVD therapy.\n\nID: 42421220\nTitle: Discovery of Novel Isoxazole-Based FXR Agonists Containing a 1,2,4-Oxadiazol-5(4H)-one Ring.\nAbstract: Farnesoid X receptor (FXR) is a member of the ″metabolic″ subfamily of nuclear receptors and is mainly present in the liver and intestines, playing a crucial role in bile acid homeostasis, inflammation, and fibrosis. Activation of FXR has emerged as a promising therapeutic strategy for treating metabolic dysfunction-associated steatohepatitis (MASH) or other FXR-dependent diseases. Here, we report our work on the discovery of a series of isoxazole-based FXR agonists containing an oxadiazolone ring. 40 compounds were designed and synthesized based on scaffold hopping and bioisostere strategies. In particular, compound 34 (Linafexor) is a potent FXR agonist with favorable pharmacokinetic properties, high liver distribution, and ideal in vivo efficacy. It has completed Phase II clinical trial for patients with MASH and is currently undergoing a Phase III clinical trial for patients with primary biliary cholangitis (PBC). This article discusses the synthesis and biological properties of this type of new molecules.\n\nID: 42420833\nTitle: Harnessing probiotics to combat nonylphenol toxicity: a multiomics approach of gut microbiome remodelling in Silurus meridionalis.\nAbstract: As a ubiquitous environmental endocrine disruptor, nonylphenol (NP) threatens aquatic organisms, driving the need for sustainable mitigation strategies. While probiotics represent promising eco-friendly supplements, their molecular mechanisms against NP toxicity remain unclear. In this study, S. meridionalis received 7-week of probiotic (Bacillus subtilis and Lactobacillus acidophilus) pretreatment followed by 15 days of NP exposure. Integrated metagenomics, transcriptomics, and metabolomics analyses, with Reverse transcription quantitative real-time PCR (RT‒qPCR) and Enzyme-linked immunosorbent assay (ELISA) validation, were performed to elucidate microbial, genetic and metabolic responses. Growth performance, including the specific growth rate (SGR) and weight gain rate (WGR), was concurrently assessed. NP exposure significantly suppressed WGR and SGR, and induced gut microbiota dysbiosis alongside and lipid metabolism disorders in S. meridionalis. Probiotic pretreatment effectively reversed these toxic effects and restored the inhibited WGR and SGR. Multiomics integration revealed that the protective effects of probiotics were mediated by a coherent \"microbe-host\" co-metabolism network across 3 progressive layers: (1) Microbial Remodelling: in which beneficial taxa (e.g., Bacteroides eggerthii and Cetobacterium sp.) were enriched, and the functional capacity for short-chain fatty acid (SCFA) synthesis and ethanolamine metabolism was enhanced; (2) Host Gene Regulation: in which key lipid metabolism genes (ek1, cept1, ept1, mogat2, and abcg2a) were upregulated, and lipase activity was restored; and (3) Metabolic Pathway Activation and Physiological Repair: in which the activity of the NP-suppressed Kennedy pathway was reactivated, thereby promoting phosphatidylethanolamine (PE) and phosphatidylcholine (PC) synthesis and ultimately restoring gut barrier function. These results were further were corroborated by RT‒qPCR and ELISA. This study systematically elucidated that probiotics alleviated NP toxicity by remodelling a \"microbiota-host Kennedy pathway gene-metabolite (PE and PC)-growth performance\" regulatory network. The key mechanism is the beneficial microbiota activating the host Kennedy pathway and restoring gut phospholipid homeostasis and barrier function. These findings provide a theoretical basis for developing targeted, lipid metabolism focused probiotic feed additives for use in sustainable aquaculture.\n\nID: 42420514\nTitle: Effects of hesperidin, nanohesperidin and obeticholic acid on hepatic FXR and SMAD3 in HFD/fructose-fed mice.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a growing global health concern, ranging from simple steatosis to advanced fibrosis. SMAD3 promotes liver injury, while Farnesoid X Receptor (FXR) regulates lipid metabolism and may have protective effects. This study evaluated the preventive and therapeutic effects of hesperidin, nanohesperidin and obeticholic acid (OCA) in an HFD/fructose-fed mice, focusing on FXR and SMAD3 levels. Forty-eight female C57BL/6J mice were utilized in prevention (10 weeks) and recovery (20 weeks) protocols. Hepatic and serum SMAD3 and FXR protein levels were measured by ELISA, gene expression by qPCR, and liver injury markers (ALT, AST) were also evaluated. No significant differences in body weight were observed between the experimental groups (p > 0.05). In the recovery protocol, nanohesperidin treatment exhibited the highest hepatic FXR protein levels (p > 0.05). Serum SMAD3 levels were significantly lower in hesperidin, nanohesperidin and OCA study groups than in the control group. Although there were significant reductions in AST levels in the treatment groups, no statistically significant differences were detected in hepatic mRNA expression levels for FXR or SMAD3 (p > 0.05). These findings suggest that hesperidin, nanohesperidin, and OCA may influence fibrosis-related pathways in experimental MASLD, possibly through modulation of FXR and SMAD3 signaling. The more pronounced FXR response observed with nanohesperidin indicates that formulation strategies may affect the biological activity of hesperidin.\n\nID: 42417510\nTitle: Linking (Poly)Tungstate Speciation to Toxicity and Bioaccumulation in Daphnia magna.\nAbstract: Tungsten is an emerging pollutant commonly assumed to occur as the simple oxyanion tungstate, yet it often condenses into a suite of polytungstates in polluted waters. Despite growing recognition that tungstate polymerization modulates tungsten's environmental fate, its effects on toxicity remain largely unexplored. Here, we tracked the (de)polymerization behavior of three representative (poly)tungstates and examined its associations with multiple measures of acute toxicity to Daphnia magna, including the median lethal concentration (LC50), toxicokinetics, reactive oxygen species (ROS) content, metabolomics, and histology. While tungstate remained stable, W12 metatungstate and phosphotungstate depolymerized to different extents, yielding three distinct polymerization regimes in the exposure media. Monomeric tungstate exhibited high LC50, rapid uptake and efficient excretion, weak ROS signals, and minimal disruption of intestinal integrity. Oligomeric tungstates displayed lower LC50 than tungstate, consistent with slow depuration that generated high internal burdens, ROS accumulation, and suppression-oriented metabolic responses. High-order polytungstates, despite limited uptake and low ROS levels, were associated with structural disruption including irreversible gut barrier damage and mitochondrial collapse and displayed the lowest LC50. Together, these results suggest that tungstate polymerization not only amplifies tungsten toxicity but also alters its mode of action, supporting mechanistic interpretation and prediction of its ecotoxicological dynamics.\n\nID: 42415381\nTitle: Functional Bioactive Components in Non-Bovine Milks: A Comparative Review of Health Benefits and Potential Applications.\nAbstract: Nonbovine milks are gaining significant attention in health research due to their distinct nutritional and bioactive profiles. This review summarizes the functional components─including osteopontin, lactoferrin, casein, milk fat globule membrane (MFGM), ω-3 fatty acids, exosomes, and milk oligosaccharides─found in these specialty milks and their biological activities. Preclinical evidence suggests these components have the potential to exert health-promoting effects, with possible applications in immunomodulation, gut barrier enhancement, neurodevelopment, anti-inflammatory, and antioxidant activities. Interspecies variations in bioactive composition suggest specific nonbovine milks may offer targeted advantages for various health applications. However, given that most findings derive primarily from in vitro and animal studies, well-designed human clinical trials are necessary to validate these potential health benefits and elucidate underlying mechanisms in humans. This review highlights the potential of nonbovine milks as sustainable functional ingredients for tailored foods, supplements, and therapeutic formulations promoting human health.\n\nID: 42415055\nTitle: Dual regulation of bile acids: ameliorating hepatic glycolipid disorders and restoring intestinal health in HFHC-challenged Yellow River carp (Cyprinus carpio L.).\nAbstract: This study was designed to investigate how three distinct bile acids (BAs) modulate glycolipid metabolic disorders and hepatointestinal injury induced by excessive intake of lipids and carbohydrates in Yellow River carp (Cyprinus carpio L.) and elucidate the underlying mechanisms involved. Here, the fish were randomly assigned to five groups: a control group (CON), a high-fat high-carbohydrate diet (HFHC) group, a HFHC + 300 mg/kg chenodeoxycholic acid (CDCA) group, a HFHC + 300 mg/kg ursodeoxycholic acid (UDCA) group and a HFHC + 300 mg/kg hyodeoxycholic acid (HDCA) group. The results revealed that the serum triglyceride, glucose, and total cholesterol levels were significantly elevated in HFHC-fed fish, accompanied by increased glutamic-oxaloacetic transaminase (GOT) and glutamic-pyruvic transaminase (GPT) activities in the serum and hepatopancreas. However, dietary supplementation with bile acids in the HFHC diet significantly improved these negative changes. Analysis of BA-glycolipid metabolism-related gene expression and enzyme activities in the hepatopancreas revealed that CDCA and HDCA inhibited gluconeogenesis (FBPase/PEPCK/G6Pase) and lipogenesis (SREBP-1/FAS), while promoting glycogen accumulation (genes and glycogen levels) and fatty acid β-oxidation (PPARα) via activation of the FXR (farnesoid X receptor) /SHP (small heterodimer partner) pathway. In contrast, dietary UDCA supplementation increased intestinal TGR5 (takeda G protein-coupled receptor 5) expression and suppressed the activities of two key gluconeogenic enzymes, PEPCK and G6Pase. Additionally, dietary BAs supplementation alleviated HFHC diet-induced intestinal inflammation by inhibiting the NF-κB (Nuclear Factor κB) pathway. Bile acids relieved gut dysbiosis, improved microbial alpha diversity and community structure, and enriched beneficial bacteria including Cetobacterium somerae. These microbial changes eventually modulated host substance synthesis and metabolism. HE staining showed that HFHC diet caused hepatopancreatic lesions and intestinal morphological damage in Yellow River carp, which were effectively alleviated by bile acid addition. In conclusion, HFHC diets disrupt fish glycolipid metabolism and impair hepato-intestinal health in Yellow River carp, whereas dietary BAs can attenuate these detrimental effects by modulating metabolic pathways and the gut microbiota composition.\n\nID: 42413530\nTitle: Barrier restoration as a therapeutic strategy for disorders of gut-brain interaction.\nAbstract: Disorders of gut-brain interaction, such as irritable bowel syndrome and functional dyspepsia, are increasingly linked to defects in gut barrier function. Mucosal disruption, encompassing alterations in the epithelial and mucus layers, leads to enhanced intestinal permeability, microbial translocation, and aberrant immune and neuronal signalling, potentially contributing to symptom severity. Despite growing recognition of barrier dysfunction in disorders of gut-brain interaction, clinical interventions remain largely symptom-based, with few therapies designed to directly restore epithelial integrity. In this Review, we examine the cellular and molecular pathways underpinning gut barrier function and highlight evidence supporting the role of diet, microbiome-targeted interventions, stress modulation, and pharmacological agents in maintaining or restoring intestinal permeability. Mechanistic insights reveal that short-chain fatty acids, amino acids (glutamine and tryptophan), and targeted probiotics can enhance tight junction integrity and mucin secretion, whereas psychological stress, low-fibre diets, and high-fat diets disrupt these pathways. We also discuss novel therapeutics, including antihistamines, mast cell stabilisers, protease inhibitors, secretagogues, and guanylate cyclase C agonists, and emerging technologies, such as vagal nerve stimulation and barrier-protective hydrogel delivery systems. Although promising, these strategies require validation in well designed clinical trials with targeted endpoints, and patient stratification based on microbial and immune phenotypes. By integrating advances in molecular biology with translational therapeutics, interventions targeting intestinal permeability could shift the treatment paradigm for disorders of gut-brain interaction from general symptom management to personalised disease modification.\n\nID: 42411931\nTitle: Inclusion of Limosilactobacillus fermentum CECT5716 in Novel Fermented Caprine Milk: Technological and Nutritional Assessment.\nAbstract: The strain of Limosilactobacillus (Lm.) fermentum CECT5716, a lactic acid bacterium originally isolated from human milk, has shown beneficial effects on intestinal barrier dysfunction. This work aimed to evaluate the inclusion of this strain in a novel fermented goats' milk to ensure a balance between probiotic viability and physical properties of the final product. The influence of both the culture and fermentation temperatures was examined in relation to their effects on rheological properties. The probiotic-added product fermented at 42 °C showed satisfactory viscoelastic properties comparable to those of commercial products. Moreover, it is a high-protein fermented milk with an in vitro amino acid digestibility of 96.5% and a moderate content of carbohydrates and fat. The probiotic milk exhibited a distinctive amino acid and peptide profile, with various identified peptides matching sequences previously reported to be beneficial for the gut barrier and metabolic health.\n\nID: 42409332\nTitle: Exploring the potential efficacy of Ziziphus spina-christi on restoring steroid sensitivity in severe asthma.\nAbstract: To determine whether Ziziphus spina-christi adjuvant restores steroid hyporesponsiveness in severe asthma by strengthening the gut epithelial barrier and inhibiting the STING sensing pathway. Chemical profiling of Z. spina-christi extract was performed using liquid chromatography mass spectrometry (LC/MS-MS). Steroid-hyporesponsive asthma was induced with house dust mite (HDM) and cyclic-di-GMP (c-di-GMP). Mice were treated with dexamethasone, Z. spina-christi, or combination therapy. The study assessed gut histopathology, epithelial tight junction proteins, lung inflammation, airway hyporesponsiveness, inflammatory phenotypes, STING pathway activation, and glucocorticoid response. Z. spina-christi exhibited a flavonoid-dominated chemotype enriched in quercetin-related compounds. Severe asthma induction was associated with significant gut epithelial injury, loss of tight junction proteins, and barrier dysfunction. Dexamethasone monotherapy failed to restore gut architecture or tight junction integrity. Conversely, Z. spina-christi markedly improved gut histology and reinstated expression of Claudin-1, Occludin, and ZO-1, with near-complete normalization observed with combination therapy. Restoring the gut barrier was associated with decreased airway inflammation, improved lung function, suppression of the STING pathway, and normalization of the GRα/GRβ ratio. Z. spina-christi enhances steroid sensitivity in severe asthma by restoring the gut epithelial barrier and reducing STING-driven inflammation.\n\nID: 42409325\nTitle: Dysregulation of the bile acid signaling network in non-alcoholic fatty liver disease: Mechanisms and a new paradigm of precision network pharmacology.\nAbstract: Non-alcoholic fatty liver disease (NAFLD) has emerged as the most prevalent chronic liver disease worldwide, characterized by complex pathogenesis and a lack of effective therapies. The bile acid (BA) \"synthesis-transport-signaling\" axis serves as a central hub integrating gut microbiota, host metabolism, and immunity, and its network dysregulation is a key driver of NAFLD progression. This review systematically elaborates how dysfunction of key enzymes, transporters, and receptors (e.g., farnesoid X receptor (FXR), Takeda G protein-coupled receptor 5 (TGR5)) within this axis drives hepatic steatosis, inflammation, and fibrosis by reshaping the BA pool, disrupting enterohepatic circulation, and perturbing receptor cross-talk. Current pharmacological strategies targeting single nodes are constrained by interspecies differences in BA profiles, network complexity, and off-target effects, posing significant challenges to their efficacy and safety. Consequently, we propose a paradigm shift from \"single-target\" approaches towards \"precision network pharmacology.\" This entails developing novel bile acid conjugates, dual-target or multi-target agents, designing rational combination therapies, and stratifying patients based on their BA metabolic phenotypes. Guided by human-relevant models and novel biomarkers, this framework aims to systemically restore BA signaling network homeostasis and enable personalized intervention, offering a novel theoretical and translational roadmap for conquering NAFLD.\n\nID: 42407107\nTitle: Farnesoid X receptor blockade attenuates morphological damage, intestinal secretion, and prevents mucus loss induced by SARS-CoV-2 spike protein in the mouse intestine.\nAbstract: The SARS-CoV-2 spike protein has been implicated as an important pathogenic factor, including in intestinal disorders. The farnesoid X receptor (FXR), a nuclear receptor highly expressed in the intestine, has been highlighted in several studies investigating its role in different intestinal dysfunctions. This study evaluated whether FXR blockade attenuates spike-induced morphological alterations and intestinal dysfunction. Balb/c mice were divided into three groups (PBS, Spike, and DY268-antagonist). A 2-3 cm jejunal loop was surgically prepared, and different substances were inoculated into the loops (200 μl of PBS or 200 μl containing 10 μg of spike protein or 100 μl of DY268 at μmol + 100 μl of spike), followed by 4-h resting period before euthanasia. Chloride (Cl-) was measured, and tissue samples were collected for histomorphometry analysis, mucin and MUC2 evaluation, Paneth cell assessment, malondialdehyde (MDA), and glutathione (GSH) levels. FXR antagonism attenuated alterations in all histomorphometric parameters, maintained mucin expression and Paneth cells and their granules, and reduced MDA levels, while restoring GSH in the intestinal loop. However, further studies are needed to understand the mechanisms by which FXR blockade modulates spike-induced intestinal effects. These findings may provide insights into novel targeted strategies for the management of intestinal disorders.\n\nID: 42404979\nTitle: Exercise-induced intestinal barrier dysfunction: a potential contributor to athlete mental health.\nAbstract: Athlete mental health has become a growing concern across endurance, aesthetic and weight-sensitive sports. While psychosocial factors play major roles, emerging evidence suggests biological pathways related to gastrointestinal function may contribute. Intense exercise induces transient intestinal barrier dysfunction through splanchnic hypoperfusion, hyperthermia and tight-junction disruption, increasing permeability and microbial product exposure. These changes resemble biomarker patterns in psychiatric populations, where elevated zonulin, lipopolysaccharide and intestinal fatty-acid binding protein are associated with anxiety, depression and neuroinflammation. This viewpoint proposes a bidirectional model linking exercise-induced gut barrier stress and mood disturbance. Gut-derived signals including vagal afferent activation and cytokine-mediated tryptophan-kynurenine shifts may influence mood-regulating brain regions, while psychological stress reciprocally impairs gut integrity via corticotropin-releasing hormone and sympathetic activation. Female athletes may face heightened vulnerability through hypoestrogenic states and psychosocial pressures. While exercise physiology and psychiatric literatures remain separate, their convergence highlights an under-recognised dimension of athlete health warranting clinical awareness and Relative Energy Deficiency in Sport integration. Research priorities include longitudinal athlete studies and multi-omics approaches to determine whether gut barrier dysfunction is a contributor, modifier or parallel correlate of athlete mental health.\n\nID: 42404158\nTitle: Comparative effects of β-glucan and mannan oligosaccharides on heat stress-induced inflammation: associations with gut barrier integrity and intestinal microbiota in mice.\nAbstract: Heat stress poses serious threats to human and animal health by inducing systemic inflammation, oxidative stress, and intestinal barrier damage, yet the potential of functional food components in mitigating heat stress-associated health impairments remains insufficiently explored. This study used a chronic heat stress model in C57BL/6 J mice to compare the protective effects of β-glucan (BG) and mannan oligosaccharides (MOS) against heat stress-induced injury. The underlying mechanisms of each supplement were also systematically investigated. The results demonstrated that both BG and MOS effectively attenuated heat stress-induced body weight loss, elevated liver index, and systemic inflammatory responses, significantly reduced serum levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and heat shock protein 70 (HSP70), and restored antioxidant enzyme activity. Notably, BG exhibited superior efficacy in suppressing pro-inflammatory cytokines and restoring serum immunoglobulin A (IgA) levels. Regarding intestinal barrier integrity, both oligosaccharides markedly upregulated the colonic expression of tight junction proteins zonula occludens-1 (ZO-1), Claudin-1, and Occludin, decreased serum diamine oxidase (DAO) and lipopolysaccharide (LPS) levels, and partially alleviated heat stress-induced intestinal barrier disruption. Hepatic tissue analysis revealed that both BG and MOS ameliorated heat stress-induced hepatic inflammation and lipid metabolism dysfunction. This was achieved by suppressing TLR4 and iNOS expression while restoring the balance of CD36 and PPARα expression. Furthermore, fecal microbial diversity analysis revealed that MOS was associated with increased abundance of Lachnospiraceae-related taxa, which are known to include short-chain fatty acid-producing bacteria. These microbial changes may contribute to the maintenance of gut microecological homeostasis via distinct microbiota-associated pathways. Collectively, these findings suggest that BG and MOS may alleviate multi-level heat stress-induced damage, potentially in association with improved intestinal barrier-related markers, altered gut microbiota composition, and modulation of gut-liver axis-related responses, thereby providing preliminary evidence for their potential application as functional food components to address heat stress-related health challenges.\n\nID: 42404072\nTitle: Evaluation of dietary curcumin-loaded mesoporous silica nanoparticles on growth, blood biochemistry, gut barrier integrity and enteric gas emissions in weaned piglets.\nAbstract: Weaning stress often impairs growth, metabolic function, gut barrier integrity, and microbial balance in piglets, underscoring the need for effective nutritional interventions to enhance post-weaning health. This study evaluated the effects of dietary curcumin-loaded mesoporous silica nanoparticles (SL@Cur) on growth performance, serum biochemical profiles, antioxidant capacity, gut epithelial integrity, gut microbial diversity, and fecal noxious gas emissions in weaned piglets. Thirty-six piglets (Duroc × [Yorkshire × Landrace]; 28 ± 1 days of age; 6-7 kg) were randomly assigned to diets containing 0, 30, or 60 mg/kg SL@Cur for 21 days. Piglets fed 30 or 60 mg/kg SL@Cur exhibited significantly higher final body weight, weight gain and average daily gain compared with control diet (p < 0.05). Myogenic gene expressions such as Pax7, Myf5 and Myf6 were significantly enhanced in piglets fed at 60 mg/kg SL@Cur compared to the control diet (p < 0.05). Serum triglycerides and total cholesterol levels were significantly reduced at 30 mg/kg (p < 0.05). The 30 mg/kg dose of SL@Cur also significantly decreased alanine aminotransferase and increased high-density lipoprotein concentrations than the control diet (p < 0.05). Serum glucose declined dose-dependently, whereas superoxide dismutase and cortisol remained unaffected. Gut barrier integrity was enhanced, as evidenced by significantly increased expression of tight junction proteins, zonula occludens-1 (ZO-1) and claudin-2 concentrations in SL@Cur supplied diets (p < 0.05). Analyzing the piglets' intestinal microbiomes showed that different dietary treatments lead to variations in their bacterial communities. As a result, the lower dose increased the presence of probiotics and lactic acid bacteria, while the higher dose showed more bacterial taxa and a mixed microbial shift. Additionally, SL@Cur markedly reduced fecal NH₃ and H2S gas emissions (p < 0.05). Overall, SL@Cur supplementation enhanced growth performance, improved metabolic and intestinal health parameters, and reduced enteric gas emissions in weaned piglets.\n\nID: 42401310\nTitle: Mucin degradation by Akkermansia muciniphila promotes Alistipes-dependent tryptophan metabolism and Th17-driven autoimmunity.\nAbstract: Multiple sclerosis (MS) is an autoimmune disorder of the central nervous system associated with alterations in gut commensals, including Akkermansia muciniphila (A. muciniphila). However, its role in MS remains unclear. Here, we report elevated serum lipopolysaccharide (LPS) and anti-LPS IgG levels in patients with relapsing-remitting MS (RRMS), indicating compromised gut barrier integrity. Notably, RRMS patients also exhibited increased serum anti-A. muciniphila IgA and enhanced A. muciniphila-induced Th17 responses in peripheral blood mononuclear cells (PBMCs). Using experimental autoimmune encephalomyelitis (EAE), a mouse model of MS, we found that A. muciniphila colonization worsened EAE severity, with increased infiltration of GM-CSF+CD4+ and IL-17A+CD4+ T cells in spinal cord. Mechanistically, A. muciniphila colonization enhanced tryptophan metabolism and elevated levels of aryl hydrocarbon receptor (AhR) agonists, including indole derivatives, during EAE. Although A. muciniphila does not directly metabolize tryptophan, it promotes expansion of tryptophan-utilizing bacterium Alistipes onderdonkii (A. onderdonkii) through mucin degradation. We further demonstrate that A. onderdonkii utilizes mucin-derived metabolites, including galactose and N-acetylneuraminic acid (NANA). Importantly, dietary tryptophan restriction significantly attenuated EAE severity. Collectively, these findings reveal a cross-feeding mechanism in which A. muciniphila supports growth of A. onderdonkii, thereby enhancing microbial tryptophan metabolism and production of AhR agonists that drive Th17-mediated neuroinflammation.\n\nID: 42400257\nTitle: Microbial metabolite Urolithin A protects against inorganic arsenic-induced gut barrier dysfunction in humanized AS3MT mice.\nAbstract: Chronic exposure to inorganic arsenic (iAs) remains a major environmental health concern and is associated with significant gastrointestinal (GI) disorders, including gastroenteritis, diarrhea, and inflammatory bowel disease-like symptoms. Gut microbiota plays a critical role in mitigating arsenic toxicity, as germ-free or antibiotic-treated mice exhibit reduced fecal arsenic excretion and greater tissue accumulation. We previously showed that the microbial metabolite Urolithin A (UroA) protects against iAs-induced cytotoxicity, apoptosis, oxidative stress, and ROS production in vitro. In this study, using humanized AS3MT mice (mouse arsenic methyltransferase gene (As3mt)replaced with human AS3MT, hAS3MT), we evaluated the in vivo effects of iAs and UroA on gut barrier function. Long-term iAs exposure (100 ppb for 28 weeks) significantly reduced expression of tight junction proteins, indicating compromised intestinal barrier integrity. UroA treatment protected hAS3MT mice from iAs-induced gut permeability, inflammation, colon shortening, and elevated colon weight/length ratio. UroA also reduced iAs-induced inflammatory cytokines, myeloperoxidase (MPO) activity and preserved intestinal epithelial cell tight junction protein expression. Further, microbiome and metabolomic analysis suggested that UroA treatment protected from iAs-induced gut microbial dysbiosis, especially restored several beneficial bacterial strains and short chain fatty acids (e.g., acetate and butyrate) and led to gut homeostasis. Together, these findings demonstrate that UroA mitigates iAs-induced gut toxicity and restores microbiota homeostasis.\n\nID: 42399316\nTitle: Gut barrier integrity biomarkers are associated with increased inflammation and predict disease status in hospitalized COVID-19 patients.\nAbstract: The COVID-19 global pandemic persists as an endemic disease with case spikes and a significant continued burden on public health. One hallmark of severe COVID-19 is a dysregulated immune response that leads to systemic inflammation and contributes to disease severity but is not explained by viral replication alone. Severe COVID-19 has been shown to disrupt the gut microbiome and increase intestinal permeability which may contribute to immune dysregulation and systemic inflammation. Here, we investigated the differences in plasma biomarkers for intestinal permeability as well as circulating cytokines between healthy volunteers and patients hospitalized with COVID-19. Correlation analyses were used to characterize differences in biomarker relationships between groups, and a random forest model was used to assess their discriminative accuracy. Our results demonstrated that hospitalized COVID-19 patients have elevated concentrations of pro-inflammatory cytokines and microbial translocation markers, and the relationships between these biomarkers were significantly altered compared to healthy volunteers, especially those related to mucosa-associated homeostatic cytokines IL-17A and IL-23. Further, IL-6 and LBP were the top biomarkers for prediction accuracy in the random forest model. This work highlights the importance of managing microbial translocation in COVID-19 and its potential utility as a biomarker for disease severity.\n\nID: 42398207\nTitle: Kaempferitrin attenuates DSS-induced colitis by promoting ubiquitination-mediated degradation of the nuclear factor kappa B p65.\nAbstract: Inflammatory bowel disease (IBD), including colitis, is commonly associated with dysfunction of the intestinal barrier and inflammatory responses. Current medications used to treat IBD may cause severe side effects with long-term use. Previous studies have confirmed that Bupleuri Radix extract exhibits significant anti-inflammatory effects. However, the therapeutic effects of its active component, kaempferitrin (KPN), on dextran sulfate sodium (DSS)-induced colitis in mice and the underlying mechanisms remain largely unexplored. The aim of this study was to investigate the therapeutic effects of KPN on colitis in mice and explore its potential mechanisms. This study employed a DSS-induced colitis mouse model to evaluate KPN's therapeutic effects. Mice were divided into control, model, 5-Aminosalicylic Acid (5-ASA), and KPN treatment groups, followed by DAI, histopathology, inflammatory cytokines, gut barrier proteins, and gene expression. This investigation revealed that Kaempferitrin (KPN), an active constituent within Bupleuri Radix extract, attenuates pathological manifestations, inflammatory cascades, and barrier dysfunction in dextran sulfate sodium (DSS)-induced murine colitis. Integrative network pharmacology and transcriptomic analyses identify NDRG2 as a potential target of KPN in the treatment of colitis. Co-immunoprecipitation (Co-IP) and mass spectrometry showed that KPN enhanced the interaction between NDRG2 and NF-κB p65, whereas mechanistic studies in bone marrow-derived macrophages (BMDMs), supported by public single-cell RNA-seq analysis and NDRG2/F4/80 co-localization in inflamed colon tissues, indicated that macrophages represent a relevant cellular context for the KPNNDRG2-p65 axis. Through the utilization of a biotin-conjugated KPN probe, direct molecular interaction between KPN and NDRG2 was established, with site-directed mutagenesis revealing E164, P280, and M314 as critical amino acid residues mediating this interaction. Mechanistically, KPN promoted NDRG2-associated recruitment of FBXO11, facilitating K48-linked ubiquitination and proteasomal degradation of p65 in BMDMs, thereby suppressing NF-κB activation and inflammatory cytokine expression. Additionally, in vivo experimental evidence indicated that NDRG2 ablation (NDRG2-/-) substantially diminished the protective efficacy of KPN against DSS-induced colitis and compromised its capacity to inhibit p65. KPN directly engages NDRG2 and modulates a BMDMs-associated NDRG2-FBXO11-p65 axis to restrain NF-κB signaling, providing mechanistic insight into the anti-inflammatory effects of KPN in experimental colitis.\n\nID: 42398186\nTitle: Molecular crosstalk of probiotics in gut health: A chemical perspective on metabolite-mediated pathways.\nAbstract: Intestinal diseases, encompassing conditions like inflammatory bowel disease, irritable bowel syndrome, and colorectal cancer, represent a significant global health burden. Their pathogenesis is intricately linked to gut microbiota dysbiosis, which disrupts intestinal barrier integrity and immune homeostasis. Probiotics, as live beneficial microorganisms, have emerged as promising therapeutic agents to restore gut ecological balance and alleviate disease symptoms. This review comprehensively synthesizes current knowledge on the multifaceted mechanisms of action of probiotics against intestinal diseases. It delves into their ability to regulate gut microbial composition, strengthen the intestinal barrier, modulate immune and inflammatory responses, influence host-microbe co-metabolism (e.g., SCFAs, bile acids, tryptophan), and alleviate oxidative stress. Furthermore, it evaluates their clinical applications across a spectrum of intestinal disorders and discusses emerging strategies such as engineered probiotics and postbiotics. Probiotics exert their beneficial effects through a complex interplay of mechanisms, including competitive exclusion of pathogens, production of antimicrobial compounds, and immunomodulation. Preclinical models demonstrate their considerable potential in ameliorating disease-specific pathologies by restoring microbial balance and enhancing gut barrier function. Future perspectives highlight the potential of precision interventions via strain synergy optimization, genetic engineering, and harnessing microbial metabolites, positioning probiotics as next-generation, targeted therapeutics for intestinal health management.\n\nID: 42397592\nTitle: Host-derived Limosilactobacillus reuteri supplementation improves piglet growth and gut integrity in heat-stressed sows.\nAbstract: Heat stress during late gestation and lactation impairs sow physiology and productivity, partly through altered stress responses, inflammation, and intestinal integrity. This study evaluated whether novel Limosilactobacillus reuteri strains isolated from high-performing sows under heat stress could mitigate these effects. Forty multiparous sows (twenty sows in parity three and twenty in parity four; average initial BW: 243.1 ± 18.2 kg) were assigned to a thermoneutral control (TN) or three heat-stress treatments: unsupplemented heat stress (HS), heat stress with a 4.65 log CFU/g L. reuteri (HS5), or heat stress with a 4.95 log CFU/g L. reuteri (HS10). Sow performance, stress indicators, inflammatory cytokines, antioxidant status, gut integrity markers, and fecal microbiota were assessed. Feed intake during lactation was higher in the TN and HS10 compared with the HS. Litter performance parameters showed no significant differences among groups. Piglet weight at weaning was increased (p = 0.015) in the TN and HS10 compared with the HS and HS5. Respiratory rate increased in heat-stressed sows. Hair cortisol concentrations were lower in the TN compared with the heat-stressed treatments. Serum tumor necrosis factor-alpha, interleukin (IL)-10, and IL-1β concentrations were lower in TN compared with heat-stressed groups. Serum zonulin was higher in HS than in TN and HS10, while occludin concentration was lower in TN compared with all heat-stress treatments. At the phylum level, the relative abundance of Firmicutes, Bacteroidota, and Spirochaetota was similar among groups. At the family level, the Pirellulaceae family was tended to be higher in HS than HS5 and HS10. At the genus level, the relative abundance of Terrisporobacter was higher in the HS10 compared with HS and HS5. Abundance of CPla-4_termite_group tended to increase in the HS. Supplementation with 4.95 log CFU/g host-derived L. reuteri strains improved feed intake and piglet growth under heat stress and modulated inflammatory and gut barrier markers, despite minimal effects on overall microbiota structure.\n\nID: 42396442\nTitle: Gut barrier-microbiota crosstalk in sepsis: from pathogenesis to potential therapies.\nAbstract: Sepsis is a systemic inflammatory response syndrome triggered by infection, frequently complicated by severe organ dysfunction and high mortality rates. Recent studies of intestinal epithelial function and the gut microbiota have highlighted their pivotal roles in the pathogenesis of sepsis. However, the precise mechanisms governing the interaction between the intestinal epithelium and gut microbiota, and how this interaction drives sepsis progression, still need to be elucidated. In this review, the functions of the intestinal epithelial barrier are first outlined, and the clinical significance of its altered permeability during sepsis is highlighted. Then, the physiological roles of the gut microbiota are further explored, detailing how dysbiosis and microbial metabolites influence disease progression and trigger both localized and systemic immune responses. Based on this, a logical framework for gut-originated systemic inflammation is proposed, and the potential adverse effects of current clinical supportive therapies on intestinal integrity are further discussed. Finally, the emerging sepsis treatment strategies that target gut function are summarized, aiming to provide novel insights and therapeutic directions for clinical practice.\n\nID: 42394828\nTitle: Gut barrier dysfunction and multidrug-resistant bacterial translocation in adult critical illness: Mechanistic insights from a systematic review.\nAbstract: The gastrointestinal tract plays an important role in host defence during critical illness. Disruption of epithelial integrity, microbiome imbalance, and immune dysregulation have all been linked to the translocation of multidrug-resistant (MDR) organisms from intestinal colonization to invasive infection. However, whether these associations reflect true causal mechanisms remains uncertain, and available human evidence has not been comprehensively synthesized using current methodological standards. To systematically evaluate human evidence examining the relationship between intestinal barrier dysfunction, microbial colonization, and subsequent MDR infection in adult critical illness, with particular attention to study quality, heterogeneity, and potential confounding factors. This systematic review was conducted in accordance with PRISMA guidelines. A structured literature search was performed in PubMed, EMBASE, and the Cochrane Library (2000-2025) using predefined Boolean combinations and Medical Subject Headings. Prospective and retrospective cohort studies involving intensive care units (ICU) adults were included if they evaluated intestinal colonization, biomarkers of barrier dysfunction (citrulline and intestinal fatty acid-binding protein), microbiome alterations, or endotoxemia. Study selection and data extraction were undertaken independently by two reviewers, with disagreements resolved through discussion. Risk of bias was assessed using the Newcastle-Ottawa Scale and ROBINS-I tool. Owing to methodological and clinical heterogeneity, findings were synthesized using a structured narrative approach rather than meta-analysis. Across the included studies, intestinal colonization with carbapenem-resistant Enterobacteriaceae, carbapenem-resistant Klebsiella pneumoniae, Acinetobacter baumannii, and vancomycin-resistant Enterococcus was consistently associated with an increased risk of subsequent bloodstream infection. However, progression rates varied considerably across cohorts, likely reflecting differences in patient characteristics, antimicrobial exposure, and ICU practices rather than a consistent effect size. Biomarker studies showed reduced citrulline levels and elevated intestinal fatty acid-binding protein concentrations in patients with gastrointestinal dysfunction; however, these markers indicate enterocyte injury rather than directly measuring intestinal permeability or bacterial translocation. Microbiome analyses demonstrated reduced diversity and impaired colonization resistance, although the extent and timing of these changes were not uniform across studies. Taken together, the evidence supports a biologically plausible link between epithelial injury, dysbiosis, and infection risk, but does not establish a direct causal relationship, largely due to the observational design of available studies and the influence of confounding factors such as illness severity, antimicrobial exposure, and ICU environment. Gut barrier dysfunction appears to contribute to the pathogenesis of MDR infection in critically ill adults; however, current evidence supports association rather than causation. Early recognition of intestinal colonization and strategies aimed at preserving mucosal integrity may offer potential clinical benefit, although their effectiveness requires confirmation in well-designed prospective and interventional studies.\n\nID: 42394565\nTitle: [Oral-gut axis: the microbial and immune bridge linking periodontitis to inflammatory bowel disease].\nAbstract: Periodontitis and inflammatory bowel disease (IBD) are common chronic inflammatory diseases affecting the oral cavity and gut, respectively. Recent researches suggest a potential bidirectional link between them via the oral-gut axis. On one hand, periodontal pathogens, notably Porphyromonas gingivalis, can ectopically colonize the gut, driving and exacerbating intestinal inflammation through mechanisms such as disrupting the gut barrier and inducing helper T cell 17/regulatory T cell imbalance. On the other hand, the systemic inflammatory environment, immune-metabolic disturbances, and oral-specific lesions caused by IBD can significantly increase the risk and severity of periodontal tissue destruction. This review summarizes the current understanding of the microbial and immune mechanisms underlying the interrelationship between periodontitis and IBD. It aims to encourage further validation of causality through longitudinal cohort studies, exploration of microbiome-targeted interventions, and multidisciplinary collaboration, ultimately facilitating the development of integrated prevention and treatment strategies based on the oral-gut axis. 牙周炎和炎症性肠病（IBD）分别是口腔和肠道常见的慢性炎症性疾病。近年研究发现，两者可能通过口腔-肠轴存在双向关联。一方面，以牙龈卟啉单胞菌为代表的牙周致病菌可异位定植于肠道，通过破坏肠道屏障、诱导辅助性T细胞17/调节性T细胞失衡等机制驱动并加剧肠道炎症；另一方面，IBD所致的全身性炎症环境、免疫代谢紊乱以及口腔特异性病变，亦可显著增加牙周组织破坏的风险与严重程度。本文综述了牙周炎与IBD在微生物与免疫机制方面的相互关联及研究进展，以期通过纵向队列研究、微生物组靶向干预及多学科协作，进一步验证牙周炎与IBD的因果关联并探索基于口腔-肠轴的联合防治策略。.\n\nID: 42393343\nTitle: Docosahexaenoic acid alleviates DSS-induced colitis by regulating the gut microbiota and restoring the gut barrier.\nAbstract: Docosahexaenoic acid (DHA), a long-chain omega-3 polyunsaturated fatty acid, has well-recognized anti-inflammatory activity; however, the mechanisms underlying its protective effects in inflammatory bowel disease (IBD) remain incompletely understood. In this study, we investigated the effects of DHA in a dextran sulfate sodium (DSS)-induced mouse model of colitis and examined whether these effects were mediated by the gut microbiota. DHA administration markedly alleviated DSS-induced colitis, as indicated by reduced body weight loss, disease activity, mortality, colon shortening, histological injury, intestinal barrier disruption, and colonic inflammatory responses. 16 S rRNA gene sequencing showed that DHA reshaped the gut microbial community and increased the abundance of beneficial taxa, including Bifidobacterium. Antibiotic cocktail (ABX)-mediated microbiota depletion largely abolished the protective effects of DHA, whereas fecal microbiota transplantation (FMT) from DHA-treated donors transferred resistance to DSS-induced colitis to recipient mice. DHA also restored tight junction protein expression and increased the frequency of colonic regulatory T cells in a microbiota-dependent manner. These findings indicate that DHA alleviates experimental colitis by modulating the gut microbiota, restoring intestinal barrier integrity, and regulating mucosal immune homeostasis. DHA may therefore represent a promising dietary strategy for the prevention or adjunctive treatment of ulcerative colitis (UC).\n\nID: 42392748\nTitle: [Ameliorating effect of Citri Reticulatae Pericarpium on hypercholesterolemia in rats through promoting reverse cholesterol transport].\nAbstract: This study aimed to elucidate the therapeutic potential and underlying mechanisms of the Citri Reticulatae Pericarpium extract(CRPE) against hypercholesterolemia. A hypercholesterolemic rat model was established through a combination of a high-sugar, high-fat diet and ethanol administration. The experimental animals were systematically divided into several groups, including a normal control group, a disease model group, a positive control group treated with ezetimibe(1 mg·kg~(-1)), and three intervention groups receiving low, medium, and high doses of CRPE(1.25, 2.5, and 5 g·kg~(-1), respectively). High performance liquid chromatography(HPLC) revealed that CRPE mainly contained narirutin, hesperidin, and nobiletin. A comprehensive series of in vivo assessments were conducted to evaluate effects of the extract. These included measuring serum lipid levels and calculating the atherogenic index(AI) using an automated biochemical analyzer, quantifying total cholesterol(TC) and total bile acid(TBA) levels in liver tissues and fecal samples with commercial assay kits, evaluating microcirculatory blood perfusion in the tail using the Moor FLPI laser speckle contrast imaging system, and measuring hemorheological parameters with an automated hemorheometer. Furthermore, enzyme-linked immunosorbent assay(ELISA) was employed to measure the serum and hepatic levels of critical factors involved in cholesterol transport and metabolism. The expression of proteins related to the reverse cholesterol transport(RCT) pathway and bile acid synthesis and metabolism in the liver was meticulously examined by Western blot. In vitro cell experiments were performed to validate the effects of CRPE on cholesterol uptake and efflux in BRL and RAW264.7 cells. The findings demonstrated that CRPE effectively corrected dyslipidemia, enhanced microcirculatory perfusion, and ameliorated abnormal blood rheology. It reduced serum levels of oxidized low-density lipoprotein(ox-LDL), apolipoprotein B(ApoB), free cholesterol(FC), cholesteryl ester(CE), and acyl coenzyme A: cholesterol acyltransferase(ACAT), while simultaneously increasing the levels of lecithin: cholesterol acyltransferase(LCAT) and apolipoprotein A1(ApoA1). A notable reduction in hepatic TC and a significant increase in TBA content in both the liver and feces were observed. Mechanistically, the hypocholesterolemic effect of CRPE was attributed to its ability to upregulate the expression of pivotal proteins in the RCT pathway, including the low-density lipoprotein receptor(LDL-R), scavenger receptor class B type I(SR-BI), ATP-binding cassette sub-family G member 5(ABCG5), ATP-binding cassette sub-family G member 8(ABCG8), and ATP-binding cassette subfamily B member 1(ABCB1). Concurrently, CRPE modulated the expression of central regulators of bile acid homeostasis, such as the bile salt export pump(BSEP), the farnesoid X receptor(FXR), and cholesterol 7α-hydroxylase(CYP7A1). The in vitro experiments provided compelling corroborating evidence, showing that CRPE directly stimulated the uptake of NBD-cholesterol in BRL hepatocytes and promoted its efflux from RAW264.7 macrophages. In conclusion, CRPE ameliorates hypercholesterolemia by facilitating RCT and maintaining enterohepatic circulation homeostasis of bile acid.\n\nID: 42392352\nTitle: Renal failure-driven luminal ammonia production impairs gut barrier function in CKD.\nAbstract: Chronic kidney disease (CKD) is often associated with increased intestinal permeability, commonly referred to as \"leaky gut.\" This study aimed to investigate how uremic conditions affect gut barrier integrity using in vitro, ex vivo, and in vivo models. Caco-2 cells exposed to plasma from hemodialysis (HD) patients exhibited increased permeability. HD plasma selectively upregulated claudin-1 expression at both mRNA and protein levels, without affecting ZO-1 or occludin. Uremic toxins such as indoxyl sulfate and p-cresyl sulfate did not replicate these effects. CKD mice showed enhanced paracellular intestinal permeability, confirmed by elevated plasma levels of LBP and FD4, both in vivo and ex vivo. Claudin-1 overexpression was also observed in the colons of CKD mice. In addition, CKD mice displayed increased cecal ammonia concentrations. Exposure to ammonia, both in vitro and ex vivo, significantly disrupted epithelial barrier integrity and increased colonic permeability, supporting the hypothesis that bacterial urease activity and ammonia production contribute to gut barrier dysfunction in CKD. These findings reveal a potential mechanistic link between renal failure, luminal ammonia, and \"leaky gut.\"\n\nID: 42390972\nTitle: Developmental maturation of intestinal junctional complexes in preterm infants.\nAbstract: Preterm infants are prone to gastrointestinal complications such as infectious diseases and necrotizing enterocolitis, which are associated with intestinal inflammation and increased intestinal permeability. Intestinal epithelial barrier (IEB) function is known to be immature in preterm neonates; however, our understanding of how the IEB develops - particularly the formation of junctional complexes - remains limited. Here, we analyzed intestinal tissue specimens from healthy resection margins of six very immature preterm infants who underwent bowel resection due to focal intestinal perforation (at the chronological age of 25 to 28 weeks' gestation), and compared the composition of tight junctions, adherens junctions and desmosomes to that of adults. Using immunostaining, our observations show, that tight junction proteins Claudin-2, Claudin-3 and Occludin, adherens junction proteins E-cadherin and β-Catenin as well as desmosomal proteins Plakoglobin and Plakophilin-2 appeared as mature as in adults as early as 25 weeks' gestation. However, Claudin-1, -4 and -5, as well as ZO-1 staining patterns increased and became more defined with increasing gestational age, suggesting junctional maturation during gestational week 26 and 27. Desmosomal protein Desmocollin-2 was increased until 26 weeks' gestation whereas Desmoglein-2 and Desmoplakin expression was immature at 28 weeks' gestation compared to the expression in adults. Our study provides the first sequential characterization of junctional protein maturation across all major IEB components early in life in human samples. These findings may help identify key mechanisms underlying intestinal barrier-associated pathologies in preterm infants.\n\nID: 42389671\nTitle: Leveraging artificial intelligence for analysis of the gut microbiome for dementia diagnosis: a scoping review and discussion.\nAbstract: Dementia, a multifactorial disease with progressive cognitive decline, has been linked to imbalances in the gut-brain axis. Emerging artificial intelligence tools have augmented the identification of several gastrointestinal biomarkers for differential dementia detection and severity, but current literature lacks a comprehensive review. This study aims to better quantify the applications of AI in the exploration of the gut microbiome for diagnosis of specific subtypes of dementia. Primary articles (n = 896) from any point in time through July 2025 were identified from PubMed, Web of Science, Scopus, and ScienceDirect. Title and abstract screenings filtered articles from 896 to 28 for critical appraisal and review for key bacteria, fungi, and metabolites. Methods adhered to the PRISMA extension for Scoping Reviews (PRISMA-ScR) guidelines. Several studies utilized predictive models including random forests and neural networks to demonstrate alterations in the gut microbiota of Alzheimer's disease, an increasingly prevalent dementia subtype. These individuals have notably reduced levels of butyrate-producing bacteria, such as Butyrivibrio, Eubacterium, and Faecalibacterium, which contribute to anti-inflammation and gut-barrier maintenance. Increased levels of Odoribacter splanchnicus and Klebsiella pneumoniae, as well as bacteria from generas Bacteroides and Prevotella, which help generate short-chain fatty acids, have been implicated in neuroinflammation; Roseburia inulinivorans negatively correlates with functional ability. Interestingly, superagers also display unique microbiome profiles that seemingly have protective effects linked to superior cognitive resilience. Distinct gut microbial compositions are associated with dementia. Furthermore, elucidating gut-brain interactions and their neurodegenerative implications can identify targets for earlier, synergistic diagnostics. https://osf.io/yw2dc/overview.\n\nID: 42389262\nTitle: 2-Pentadecyl-2-oxazoline alleviates anxiety-like behaviour and modulates the microbiota-gut-brain axis in obese mice.\nAbstract: A bidirectional relationship between obesity and anxiety disorders has been increasingly associated with neuroinflammation and dysregulation of the gut-brain axis. Here, we investigated the pharmacological effects of the N-palmitoylethanolamine oxazoline derivative 2-pentadecyl-2-oxazoline (C15OXA) in a mouse model of high-fat diet (HFD)-induced obesity, with particular attention to its central and peripheral mechanisms of action. Male C57Bl/6J mice were fed an HFD for 12 weeks and subsequently treated with C15OXA (30 mg·kg-1, p. o.) for 7 weeks. Behavioural, molecular, and microbiota analyses were performed to evaluate the effects of the compound. C15OXA significantly reduced anxiety-like behaviour in obese mice without affecting body weight, fat mass, or glucose tolerance. At the central level, C15OXA attenuated hippocampal neuroinflammation, as shown by reduced expression of COX-2, TLR4, NLRP3 and IL-1β. In parallel, C15OXA restored tight junction gene expression associated with blood-brain barrier integrity, and modulated unfolded protein response signalling. In addition, C15OXA enhanced markers of neurogenesis and synaptic plasticity. At the peripheral level, C15OXA treatment reduced colonic inflammation and improved gut barrier integrity. These effects were associated with a targeted reshaping of gut microbiota composition. In particular, C15OXA promoted the enrichment of butyrate- and menaquinone-producing bacteria, as taxa linked to beneficial metabolic functions. Overall, these findings suggest that C15OXA exerts anxiolytic-like effects associated with coordinated central and peripheral pathways involving the modulation of neuroinflammatory pathways, barrier integrity, and gut-brain axis signalling. This study provides novel pharmacological insight into the therapeutic potential of C15OXA for the treatment of obesity-associated neuropsychiatric disorders.\n\nID: 42389066\nTitle: Metabolic Dysfunction-Associated Fatty Liver Disease: From Pathogenesis to Treatment.\nAbstract: Metabolic dysfunction-associated fatty liver disease (MAFLD) has become the most prevalent chronic liver disease worldwide and represents a major hepatic manifestation of systemic metabolic dysfunction. The disease is closely linked to obesity and insulin resistance and progresses from simple hepatic steatosis to metabolic dysfunction-associated steatohepatitis, fibrosis, cirrhosis, and hepatocellular carcinoma. Increasing evidence indicates that MAFLD pathogenesis involves complex interactions among dysregulated lipid metabolism, mitochondrial dysfunction, oxidative stress, inflammatory signaling, bile acid imbalance, and gut microbiota-derived metabolites, reflecting the systemic and multifactorial nature of the disease. However, despite substantial progress in understanding these mechanisms, the integrated regulatory networks driving MAFLD progression and their translational therapeutic implications remain incompletely characterized. In this review, we comprehensively summarize recent advances in the molecular mechanisms underlying MAFLD, focusing on metabolic dysregulation, cellular stress responses, inflammatory pathways, and regulated cell death processes. We further highlight the critical role of interorgan communication particularly the adipose-liver and gut-liver axes and discuss emerging evidence on extracellular vesicles (EVs) as mediators of metabolic and inflammatory signaling. Finally, we evaluate current and potential therapeutic strategies, emphasizing the diagnostic and therapeutic promise of EV-based approaches in MAFLD management, and identifying emerging molecular targets for improved intervention and future clinical translation opportunities.\n\nID: 42385714\nTitle: Gut commensal Bacteroides-derived pantothenic acid alleviates metabolic syndrome.\nAbstract: Pantothenic acid (PA), or vitamin B5, can be synthesized by gut commensals, but the contribution of microbial PA to metabolic health remains unclear. Here, we find that microbial PA supply is reduced in individuals with metabolic syndrome (MetS) and is associated with impaired gut barrier function and disease severity. Tracing microbial PA identifies Bacteroides fragilis as a key contributor, with panC required for PA biosynthesis, as confirmed by isotope tracing, bacterial culture, and germ-free colonization. In MetS models, colonization with wild-type, but not ΔpanC B. fragilis, restores PA, preserves gut barrier integrity, reduces endotoxemia, and improves metabolic dysfunction. Mechanistically, microbial PA requires host pantothenate kinase activity, as silencing pantothenate kinase 2/3 (PANK2/3) in colonic organoids and in vivo reduces coenzyme A (CoA)/acetyl-CoA metabolism, suppresses Krüppel-like factor 4 (KLF4)-associated differentiation programs, and blunts the protective effects of microbial PA. Finally, a plant-derived polysaccharide enriches PA-producing Bacteroides and restores colonic PA, highlighting a strategy for colonic homeostasis and metabolic health.\n\nID: 42384365\nTitle: Toll-like Receptor 4 Knockout Mice are Protected Against PMOS-like Pathogenesis.\nAbstract: Polyendocrine metabolic ovarian syndrome (PMOS), formerly termed polycystic ovary syndrome (PCOS), is a reproductive disorder with heterogeneous symptoms and severity. Despite extensive research documenting chronic immune dysfunction as a hallmark of PMOS, the specific mechanisms of immune activation remain poorly understood. Emerging evidence suggests that gut-derived bacterial endotoxins, particularly lipopolysaccharide (LPS), can breach intestinal barriers and trigger systemic inflammation via Toll-like receptor 4 (TLR4). This study examined the role of TLR4 in PMOS-like pathology using a letrozole (LET)-induced mouse model. In LET-treated wild-type female mice, serum LPS and its carrier protein LBP were elevated compared to LET-treated TLR4-/- mice. Additionally, TLR4 deficiency attenuated multiple PMOS-like features, including elevated luteinizing hormone, anovulation, and metabolic dysfunction. LET-treated TLR4-/- mice also preserved estrous cycling and fertility, maintained gut barrier integrity, and reduced inflammatory markers. These findings support TLR4 as an important contributor to multiple features of PMOS-like pathology. This novel work highlights TLR4-mediated inflammation as a potential target for anti-inflammatory treatments in women with PMOS.\n\nID: 42436725\nTitle: In vivo targeted MRS detection of 2-hydroxyglutarate molecules in IDH-mutant gliomas via spin regulation.\nAbstract: 2-hydroxyglutarate (2-HG) is a key metabolic biomarker for identifying IDH-mutant gliomas. Non-invasive and accurate detection of 2-HG is of great significance for the early diagnosis of diseases and dynamic monitoring of therapeutic efficacy. However, conventional magnetic resonance spectroscopy (MRS) faces challenges in detecting 2-HG in vivo, mainly due to the overlap of its resonance peaks with those of metabolites such as glutamate (Glu) and N-acetylaspartate (NAA). Although the long echo time (TE) filtering method can separate signals to a certain extent, it is often accompanied by peak distortion and signal attenuation, which limits its clinical application. To address this problem, this study proposes a 2-HG-targeted detection sequence based on optimal control pulses. By applying optimal control pulses to regulate the state evolution of a 14-spin system composed of 2-HG, Glu, and NAA molecules, the study achieves selective retention of 2-HG signals and suppression of other molecular signals. In experimental verification conducted on phantoms and IDH-mutant glioma animal models, the targeted sequence exhibited excellent signal resolution performance: it efficiently retained 2-HG signals and achieved approximately 95% and 98% suppression of Glu and NAA signals, respectively. To further verify the quantitative reliability of the targeted sequence, the 2-HG concentrations measured by this sequence were compared with those obtained by liquid chromatography-tandem mass spectrometry (LC-MS/MS). A high linear correlation was found between the two sets of results, which fully confirms the accuracy of non-invasive quantitative detection of 2-HG using the targeted sequence.\n\nID: 42436634\nTitle: From raw to steamed Panax notoginseng: A systematic review of saponin transformations and their functional consequences.\nAbstract: Notoginseng Radix et Rhizoma (NRR), derived from Panax notoginseng, serves as both a functional food and a key medicinal material in traditional Chinese medicine. Its bioactivity is largely attributed to saponins, which undergo significant chemical transformations during processing (e.g., steaming), altering its pharmacological profile. This review aims to systematically consolidate experimentally verified metabolites from authenticated NRR, elucidate the chemical transformations induced by processing and clarify the resulting shift in pharmacological effects, thereby providing a scientific basis for its targeted application. A comprehensive literature search was conducted using CNKI, Wanfang Data, National Science and Technology Library, the Pharmacopoeia of the People's Republic of China, PubMed and Web of Science. Keywords included Panax notoginseng (Burk.) F. H. Chen; Pharmacological activities; Phytochemisity; Saponin transformation; Traditional processing; Traditional Chinese medicine. Data were also sourced from classic texts, dissertations and unpublished materials. Processing, particularly steaming, converts high-polarity saponins into less polar ones via deglycosylation, dehydration and hydroxylation. This chemical shift underlies a functional transition: raw NRR primarily promotes blood activation and stasis dispersion, while processed NRR exhibits enhanced blood-nourishing, antioxidant, anti-inflammatory and immunomodulatory activities. The integration of ethnopharmacological knowledge with modern scientific perspectives clarifies the metabolite pathways and mechanistic basis for processing-induced changes in NRR. This review provides a reliable foundation for the precise use and further development of NRR in functional foods, nutraceuticals and evidence-based therapy.\n\nID: 42436592\nTitle: Impact of United States marine corps recruit training on the stress response and menstrual function in female marine recruits.\nAbstract: This study investigated the physiological stress response and menstrual cycle (MC) function in Marine recruits during United States Marine Corps Recruit Training at the Marine Corps Recruit Depot in San Diego, CA. Female recruits (n = 120) completed pre- and post-RT MC surveys. Saliva samples were collected at 6 timepoints (pre-RT, weeks 1, 4, 7, 10, post-RT) and analyzed for stress biomarkers. Urine samples were collected pre-RT, 5 days per week during RT, and post-RT to assess sex hormone metabolites. Linear mixed-effects models assessed time effects (p < 0.05). Pre-RT sAA levels were higher than weeks 4 (p < 0.001), 7 (p < 0.001), and 10 (p = 0.003). Week 1 sAA levels were greater than week 7 (p = 0.049) and post-RT sAA levels were greater than week 4 (p = 0.011), 7 (p < 0.001), and 10 (p = 0.046). Cortisol at weeks 1 (p = 0.004) and 4 (p < 0.001) was greater than week 10. Before RT, 85% reported regular MCs; during RT, 53% reported irregularity. Urine measures indicated 92% experienced MC disruption, 87.5% within the first cycle. Recruits experienced heightened stress early in RT but adapted as training progressed. Most recruits exhibited MC irregularities, with disruption occurring in the first cycle, indicating heightened hypothalamic-pituitary-ovarian axis sensitivity to military training stress.\n\nID: 42436575\nTitle: Host genetic architecture and gut microbiota cooperatively regulate early growth in goats.\nAbstract: Early postnatal growth is a critical determinant of meat production efficiency and long-term genetic improvement in goats; however, the molecular mechanisms underlying individual variation in growth performance remain poorly understood. In this study, a total of 123 Hechuan white goats were included. First, a genome-wide association study (GWAS) for average daily gain (ADG) was performed using all 123 individuals. Subsequently, based on the coefficient of variation of ADG (CV = 65.6%), an extreme phenotype sampling (EPS) strategy was applied to select 39 individuals with extreme growth phenotypes for subsequent metabolomic, microbiome, and integrated mGWAS analyses.The results showed that ADG approximately followed a normal distribution across the 123 goats. GWAS identified 22 loci significantly associated with ADG, mapping to genes including DLK1, NCAPG2, LCORL, CNTNAP2, and SLC8A1, which are involved in pathways related to skeletal muscle development, cell cycle regulation, ion transport, and immune function. Metabolomic profiling detected 1,589 putative metabolites, revealing differential enrichment of lipid, amino acid, and bile acid metabolic pathways between fast- and slow-growing goats. Gut microbiome analysis demonstrated that Christensenellaceae_R-7_group and Monoglobus were significantly enriched in fast-growing individuals, whereas Desulfovibrio was more abundant in slow-growing goats.Integrated mGWAS analysis further revealed extensive effects of host genetic variation on gut microbiota and fecal metabolites. Specifically, 11 bacterial genera were significantly associated with host genomic variants, among which Desulfovibrio exhibited the highest number of associated loci. Integration of multiple variant types consistently linked Desulfovibrio, Eubacterium_hallii_group, and Candidatus_Saccharimonas with genes such as ARHGAP24 and IGF2BP2. In addition, 14 metabolites were significantly associated with host genetic variants, with Lysopc(14:1(9Z)/0:0) and glycocholic acid showing the strongest associations. Notably, the peak signal for Lysopc was located within HMGA2.Collectively, these findings define a coordinated host genome-gut microbiota-metabolite network underlying early growth variation in goats and provide a mechanistic foundation for precision breeding and targeted nutritional strategies in goat production systems.\n\nID: 42436519\nTitle: Integrating untargeted metabolomics and machine learning to reveal an aberration of sphingolipid metabolism in cardiometabolic HFpEF.\nAbstract: Cardiometabolic heart failure with preserved ejection fraction (HFpEF) is a high-risk phenotype primarily driven by metabolic syndrome, with a significantly increased incidence and risk of adverse outcomes. A fundamental reason for this is the lack of early clinical diagnosis. As a tool capable of accurately capturing pathophysiological states, metabolomics provides a critical entry point for addressing this issue; however, studies focusing on the metabolic characteristics of this population remain limited. This study integrated a clinical cohort and untargeted metabolomics to compare serum metabolic profiles between patients with cardiometabolic HFpEF and those with metabolic syndrome (MetS). Baseline characteristics were balanced using propensity score matching (PSM). Differential metabolites were identified by untargeted metabolomics, followed by KEGG pathway enrichment analysis. Machine-learning approaches were further applied to screen candidate metabolites with potential diagnostic efficacy, and weighted gene co-expression network analysis (WGCNA) together with SHapley Additive exPlanations (SHAP) were used to evaluate phenotype association and feature contribution. In an independent clinical cohort, total sphingomyelin (SM) levels were assessed by ELISA as an external evaluation strategy based on clinical applicability. Differential metabolites between the two groups were mainly enriched in sphingolipid metabolism and glycerophospholipid metabolism pathways. Through multi-method screening, C24:1 Sphingomyelin was identified as a candidate metabolite with potential diagnostic efficacy. The co-expression module containing C24:1 Sphingomyelin was significantly correlated with NT-proBNP, a key biomarker of heart failure, and SHAP analysis indicated that C24:1 Sphingomyelin contributed substantially to the classification model. In the external cohort, total SM levels were associated with disease status, suggesting the potential clinical association of sphingolipid-related signals. This study preliminarily characterized the metabolic features distinguishing cardiometabolic HFpEF from MetS alone, suggesting that sphingolipid dysregulation is associated with the development and progression of this phenotype. Among the identified metabolites, C24:1 Sphingomyelin was identified as a candidate metabolite with potential diagnostic performance, and SM showed potential clinical applicability. These findings provide new clues for biomarker discovery and preliminary clinical translational exploration in cardiometabolic HFpEF.\n\nID: 42436507\nTitle: Spectroscopic and elemental evaluation of Pb(II), Cu(II), and Hg(II) binding by salvia officinalis L. leaf extract.\nAbstract: Heavy metal contamination remains a major environmental concern because toxic ions such as Pb(II), Cu(II), and Hg(II) persist in ecosystems and pose serious risks to the environment and human health. Plant-derived extracts rich in phenolic acids, flavonoids, and other heteroatom-containing phytochemicals offer a promising natural matrix for metal binding through hydroxyl, carbonyl, and C-O-containing functional groups. This study presents a comparative matrix-level evaluation of interactions of Pb(II), Cu(II), and Hg(II) with Salvia officinalis L. leaf extract by integrating UV-Vis spectroscopic stoichiometry, apparent binding analysis, pH- and temperature-dependent spectral responses, EDTA-assisted reversibility, FTIR functional group assignments, and ICP-OES-based elemental validation. UV-Vis data were evaluated using Job's plot analysis, while apparent binding parameters were estimated using the extended Benesi-Hildebrand and Scatchard models, based on the observed stoichiometric behaviour. Pb(II) and Hg(II) exhibited apparent M₂L-type interaction patterns, whereas Cu(II) showed a 1:1 binding mode. Among the tested ions, Hg(II) produced the strongest spectroscopic binding response, followed by Pb(II) and Cu(II). The metal-extract interactions were strongly affected by pH and temperature, with more pronounced spectral responses under mildly alkaline conditions and at temperatures above 45 °C. EDTA addition indicated that the binding process was at least partially reversible, suggesting the potential regeneration of the extract-based metal-binding system. ICP-OES analysis supported the incorporation of metals into the extract-derived complexes, whereas changes in FTIR spectra indicated the involvement of hydroxyl, carbonyl, and C-O groups in metal coordination. Overall, the findings demonstrate the metal-dependent binding behavior of S. officinalis leaf extract and provide a useful spectroscopic and elemental basis for further studies on plant-derived metal-binding systems.\n\nID: 42436400\nTitle: Association of TNNI3 and MYBPC3 variants with clinical phenotype and metabolic disorders in patients with hypertrophic cardiomyopathy.\nAbstract: Hypertrophic cardiomyopathy is an inherited cardiovascular disease with heterogeneous presentation. However, the metabolic changes resulting from mutations and their relationship to the phenotype remain unclear. To investigate the association between TNNI3 and MYBPC3 variants and both clinical phenotype and metabolic disorders in HCM patients. 34 newly diagnosed HCM patients, 51 healthy individuals, and 23 unaffected family members were included. Clinical information and plasma samples were collected and analyzed. Whole-exome and Sanger sequencing were used for variant identification. Non-targeted metabolomics was performed using ultra-high-performance liquid chromatography-high-resolution mass spectrometry. TNNI3 and MYBPC3 variants were identified in familial HCM cases, which exhibited earlier onset and increased interventricular septum thickness. Metabolomics revealed lower L-valine and higher free fatty acid levels in HCM patients. Patients with TNNI3 variants showed dysregulation of lyso-phosphatidylcholines and lyso-phosphatidylethanolamines, along with disturbances in glutamic acid-related pathways. MYBPC3 variants were linked to dysregulation in energy metabolism. Correlation analysis highlighted associations between specific lipid metabolites and cardiac structure and function. Significant metabolic alterations, particularly in amino acid and lipid metabolism, are prevalent in HCM. These findings enhance our understanding of HCM pathogenesis and suggest potential biomarkers and therapeutic targets for this genetic heart disease.\n\nID: 42436254\nTitle: Functional characterization of fungal endophytes with antagonistic and plant growth-promoting activities in maize.\nAbstract: Fungal endophytes play a crucial role in plant-microbe interactions by asymptomatically colonizing host tissues, enhancing plant growth, and providing defense. In the present study, three distinct endophytic fungi, namely Fusarium oxysporum CJR-1 (GenBank Accession No. PZ477045), Penicillium sp. CJR-2 (GenBank Accession No. PZ477429) and Aspergillus cf. terreus CJR-4 (GenBank Accession No. PZ477430) were isolated from Crotalaria juncea L. plants and evaluated for antagonistic activity against phytopathogenic fungi and growth promotion in maize. Among the isolates, CJR-4 showed potent antagonistic activity against both tested phytopathogens, inhibiting the mycelial growth of Fusarium oxysporum (ITCC Accession No. 8111) and Alternaria alternata (ITCC Accession No. 1434) by 72.41 ± 5.02% and 68.31 ± 1.53%. On the other hand, isolate CJR-1 showed the highest mycelial inhibition of 74.60 ± 2.06% against A. alternata. Ethyl acetate crude metabolites of CJR-4 exhibited potent antifungal activity, with the highest zone of inhibition observed against A. alternata (21.66 ± 1.52 mm), followed by F. oxysporum (15.33 ± 1.15 mm) at 150 µL of tested concentration. GC-MS analysis of the ethyl acetate extract of CJR-4 revealed numerous bioactive metabolites, including diphenyl sulphone and 2-nonen-1-ol, which may contribute to its antifungal activity. In addition, 1-methylene-1H-indene and ethanone, 2-(formyloxy)-1-phenyl-, may be associated with antioxidant activity, as evidenced by potent DPPH (80.09 ± 0.11%) and ABTS (92.66 ± 0.17%) scavenging activities. Evaluation of PGP traits showed that CJR-1 produced the highest levels of indole-3-acetic acid (IAA) as 305.69 ± 0.41 µg mL⁻1 and ammonia 85.44 ± 0.63 µg mL⁻1, while CJR-2 exhibited the highest phosphate solubilization index (PSI) of 3.09 ± 0.09. Pot experiments conducted under natural light conditions for 28 days demonstrated significantly enhanced plant growth parameters, biomass accumulation, and photosynthetic pigment levels in maize plants inoculated with the CJR-4 isolate. Overall, the findings highlight that endophytic fungi exhibit multifunctional roles and show promise as microbial inoculants for sustainable crop improvement, with CJR-4 emerging as the promising candidate for further development. To the best of our knowledge, this study is among the first to report the isolation and functional characterization of endophytic fungi from Crotalaria juncea L. plant.\n\nID: 42436161\nTitle: Dietary glucoraphenin ameliorates obesity and steatotic liver disease associated with gut dysbiosis induced by a Western diet in mice.\nAbstract: Western-style diets promote obesity, gut dysbiosis, and metabolic dysfunction-associated steatotic liver disease (MASLD). In this study, glucoraphenin (GRE), the major glucosinolate in radish (Raphanus sativus L.) greens and sprouts, was evaluated for its effects on Western diet (WD)-induced metabolic derangements and gut dysfunction in mice. Intaking of 1 mg/kg body weight of GRE with WD for 8 weeks caused significant reductions in adipogenesis indicators such as body weight gains, adipocyte hypertrophy, and serum leptin level. This result was further proved by significant changes in lipogenesis and lipolysis-related protein expressions in adipocyte. Administration of GRE also suppressed development of MASLD, which was observed through reductions in serum ALT and AST and suppressions the expression of FAS, SREBP1, mTOR, SCD1, ACC, and ChREBP in liver tissues. GRE administration effectively prevented the decrease in the gut microbial richness and diversity caused by WD and recovered serum branched-chain amino acids and microbiota-derived purine metabolites (inosine and hypoxanthine). These findings indicate that GRE mitigates WD-induced obesity and MASLD via coordinated regulation of lipid metabolism and the gut-liver axis.\n\nID: 42436149\nTitle: ENO2 sustains cancer stemness and metastatic competence through a phosphoenolpyruvate-dependent metabolic axis in triple-negative breast cancer.\nAbstract: Enolase 2 (ENO2) is a neuron-specific glycolytic enzyme whose expression is elevated in aggressive breast cancers, yet its enzymatic and biological contributions to triple-negative breast cancer (TNBC) progression remain incompletely defined. Here, we demonstrate that ENO2 sustains cancer stem cell (CSC) properties and metastatic competence through a phosphoenolpyruvate (PEP)-dependent metabolic axis. Elevated ENO2 expression correlated with advanced tumor grade and poor clinical outcomes in TNBC cohorts, underscoring its clinical relevance. Genetic depletion of ENO2 impaired aerobic glycolysis and oxidative phosphorylation, reduced migration, invasion, and CSC frequency, and suppressed tumor growth and pulmonary metastasis in orthotopic models. Mechanistically, exogenous PEP or pyruvate restored CSC-associated traits and invasiveness in ENO2-deficient cells, supporting the functional involvement of ENO2-derived metabolites in CSC maintenance. Reconstitution with wild-type ENO2, but not a catalytically impaired mutant, restored CSC properties, invasiveness, and metastatic colonization, establishing that ENO2 catalytic activity is required for these malignant traits. Further analysis revealed that PKM2 perturbation preferentially attenuated PEP-mediated rescue while largely sparing pyruvate-mediated rescue, supporting a functional PEP-PKM2-pyruvate axis in CSC regulation. Consistently, PKM2 depletion partially blunted ENO2-mediated rescue; however, residual rescue despite PKM2 perturbation suggested additional PKM2-independent PEP-responsive mechanisms. Importantly, pharmacological inhibition of enolase with POMHEX phenocopied genetic ENO2 loss and suppressed CSC maintenance in vitro and tumor growth in vivo. Taken together, these findings identify the ENO2-driven PEP-dependent metabolic axis as a mechanistic link between metabolic reprogramming, cancer stemness, and metastasis, revealing a therapeutically actionable metabolic vulnerability in TNBC.\n\nID: 42436039\nTitle: Fermentation of plant-based foods: Microbial consortia and their impacts on composition, sensory quality, and health benefits of food products.\nAbstract: Fermented plant-based foods have obtained growing interests for their improved nutrition profile, enhanced flavor and taste, as well as their health-promoting properties. Fermentation using lactic acid bacteria (LAB) and yeasts can eliminate antinutritional components and off-flavor compounds present in plant matrices while also generating beneficial metabolites. The interaction between fermentative microbes and plant substrates is dependent on plant matrices, microbial strains, and processing conditions. Accumulating evidence indicates that fermentation modifies the generation, degradation, and bioavailability of food bioactive compounds such as bioactive peptides, vitamins, volatiles, phenolics, phytic acid and phytates, saponins, and raffinose-family oligosaccharides. This chapter reviews and critically examines research data on microbial transformations of bioactive compounds in fermented plant matrices and pinpoints key factors contributing to inconsistent findings. It also identifies key research directions for understanding and applying fermentation-driven changes to improve the nutritional and functional quality of plant-based fermented foods.\n\nID: 42436035\nTitle: Fermentation of plant- and fungal-protein foods: From processing and food properties to gut microbiome and health.\nAbstract: The shift toward plant- and fungal proteins is driven by environmental and public-health concerns, but wider adoption is constrained by poor sensory quality, limited techno-functionality, and variable nutritional performance. Fermentation has re-emerged as a versatile processing approach because it can improve flavor and texture while remaining compatible with clean-label food design. Yet the effects of fermentation designed for alternative proteins on host physiology remain largely unexplored. This chapter examines how fermentation modifies plant- and fungal-protein foods at multiple levels and how these changes may translate into health-relevant outcomes. After outlining the major chemical and physical transformations induced by fermentation, the chapter moves beyond the traditional focus on nutrients and bioactive metabolites to consider how fermentation-driven changes in flavor and food structure influence gastrointestinal signaling and digestion. Particular attention is given to how in situ production of exopolysaccharides (EPS) during fermentation reshapes matrix organization and governs the delivery of food components along the gastrointestinal tract, where they can be utilized by the host or serve as substrates for gut microbes in complex trophic chains. Accordingly, the gut microbiome provides a key interface for these processes by integrating both chemical and physical cues from foods after ingestion, while also mediating how these cues translate into physiological responses, thereby serving as a composite readout of food properties and host physiology. By highlighting what is known and where evidence is emerging, this chapter aims to support the future rational design of fermented plant- and fungal-protein foods for both product performance and health.\n\nID: 42435878\nTitle: Muribaculaceae regulate β-muricholic acid to target S1PR2 signaling and reduce neurological injury in intracerebral hemorrhage.\nAbstract: Intestinal flora imbalance after intracerebral hemorrhage (ICH) aggravates neuroinflammation and secondary brain injury through the gut-brain axis, although the specific mechanism remains unclear. This study focuses on the regulatory effects of Muribaculaceae and β-muricholic acid (β-MA, a primary bile acid) on neurological injury after ICH, aiming to reveal the molecular mechanism by which it improves the prognosis of ICH through the sphingosine-1-phosphate receptor 2 (S1PR2). A mouse ICH model was constructed by collagenase induction to evaluate the changes in gut microbiota diversity and metabolites. After intervention with Muribaculum intestinale (MI), neurological function was assessed by behavioral tests, and pathological changes of brain tissue were analyzed by Hematoxylin-Eosin and Nissl staining. Subsequently, intestinal barrier function, inflammatory factors, and total bile acid (TBA) levels were examined in ICH mice. In addition, cell viability, apoptosis, oxidative stress, inflammatory factors, and β-MA levels were analyzed in the heme-induced SH-SY5Y cell model. Molecular docking and drug affinity responsiveness target stability (DARTS) were used to analyze the interaction between β-MA and S1PR2. Intervention with a S1PR2 agonist (CYM-5520) was used to further verify the mechanism. Altered gut microbiota composition, elevated lipopolysaccharide levels, reduced expression of tight junction proteins, inflammatory activation, and disrupted bile acid metabolism were observed in ICH mice. Supplementation with MI ameliorated neural damage, cerebral edema, and neuronal loss in an intake dose-responsive manner, enhanced intestinal barrier integrity, and increased TBA levels. As a primary bile acid, β-MA directly mitigated hemin-induced oxidative stress and inflammation in neural cells. Mechanistically, β-MA downregulated the expression of S1PR2, but overexpression of S1PR2 counteracted the protective effects of β-MA. Furthermore, the administration of CYM-5520 attenuated the neuroprotective effects conferred by MI in vivo. Muribaculaceae alleviated neurological injury after ICH by upregulating β-MA levels, thereby inhibiting the S1PR2 signaling pathway. This research offers a novel approach to treating ICH by focusing on the gut microbiota-bile acid metabolism-neuroprotection axis.\n\nID: 42435811\nTitle: A classification model for predicting corticosteroid and cyclosporin: A responsiveness in pediatric idiopathic uveitis.\nAbstract: To identify serum metabolic biomarkers that distinguish corticosteroid and cyclosporin A (CS & CsA) resistant pediatric idiopathic uveitis (PIU) patients from sensitive counterparts. Serum samples were collected from 32 CS & CsA-sensitive PIU patients and 24 CS & CsA-resistant PIU patients, respectively. UHPLC-OE-MS was employed for comprehensive metabolic profiling of the serum samples. Bioinformatic analyses were performed to identify differentially expressed metabolites (DEMs) between the two patient groups. A machine learning-based classification model was constructed using the identified DEMs as predictive features. For validation purposes, an independent internal cohort of 16 CS & CsA-sensitive and 10 CS & CsA-resistant patients was recruited to evaluate the model's stability. Compared with the CS & CsA-sensitive PIU patients, serum samples from CS & CsA-resistant PIU patients displayed significant metabolic reprogramming. Among the identified differential metabolites, lipids were the most prominently dysregulated class, accounting for 72.47% of all differential metabolites. A machine learning based multivariate feature selection approach including NNET, LASSO, and XGBoost identified 4 candidate metabolite biomarkers. ROC analysis showed that three of these biomarkers (MG 15:0, PI-Cer 28:0;3O, and SPB 20:0;2O) exhibited AUC values of 0.934, 0.953, and 0.904, respectively, and were all upregulated in CS & CsA resistant patients. In contrast, N-acetylaspartic acid showed an AUC of 0.934 and was downregulated in CS & CsA resistant patients. The combined classification model incorporating these 4 metabolites achieved an AUC of 1.0. Validation in an independent internal cohort confirmed the model's excellent performance, with AUC values of 0.971 for NNET, 0.971 for LASSO, and 0.957 for XGBoost. We have established a classification model capable of effectively discriminating CS & CsA-resistant from -sensitive PIU patients. The machine learning model leveraging metabolic biomarkers demonstrates exceptional classification accuracy and generalizability, offering potential for clinical subtype classification.\n\nID: 42435809\nTitle: A Targeted Analysis of The Donor Human Milk Metabolome & Implications for Preterm Infant Nutrition.\nAbstract: Donor human milk (DHM) is widely used for preterm infants when mother's own milk (MOM) is unavailable, yet its metabolome is poorly described. To profile the metabolome of pooled, pasteurized DHM obtained from a single milk bank over a one-year period and compare it to human milk (HM) from reference cohorts. Pooled DHM (n=47) was collected weekly from the Mother's Milk Bank of Florida over 47 consecutive weeks from July 2022 to June 2023. Using 1H-NMR spectroscopy, we quantified 59 polar metabolites in DHM and compared the metabolomic profile with previously published data on HM from mothers of preterm (n=29) and term (n=97) infants collected across the first 3 months postpartum and analyzed using identical methods. Variability and group differences were assessed with regression, linear mixed-effects models, PCA, and PERMANOVA; p-values were FDR-adjusted. DHM showed limited variability, as the coefficient of variation for nearly half of the metabolites was 20-30%. Compared with both preterm and term colostrum and transitional milk, DHM had lower acetylcarnitine, myo-inositol, 3'-sialyllactose, and 6'-sialyllactose (FDR-adjusted p-value < 0.1). PCA separated HM by lactation stage and delivery type, with DHM clustering closest to term HM at 3 months postpartum and farthest from preterm colostrum. PERMANOVA and dispersion testing indicated that DHM differed significantly from all HM groups (FDR-adjusted p-value < 0.1), reflecting compositional differences related to lactation stage and reduced heterogeneity from pooling. While DHM is the preferred alternative to MOM for preterm infants, it contains lower concentrations of several potentially important metabolites than preterm HM, which may be further diluted by fortification. Future studies should evaluate how these differences and fortification may affect infant growth, development, and long-term outcomes.\n\nID: 42435668\nTitle: Mechanism of seaweed polyphenols interacting with intestinal flora to regulate blood glucose.\nAbstract: Seaweed polyphenols possess hypoglycemic biological functions, but the specific mechanisms remain unclear, which limits their further application. In this study, the area under the blood glucose curve (AUC) of the fourth-period Porphyra haitanensis polyphenols extract (FPPE)-fed mice was significantly reduced by 17.12 ± 0.87%. Moreover, FPPE exhibited α-glucosidase inhibitory activity at 64.39 ± 4.05%. In vitro fermentation experiments showed that FPPE modulated the composition of the gut microbiota, thereby enhancing the production of short-chain fatty acids (SCFAs). Analysis of intestinal flora and metabolites in mice revealed that FPPE selectively enriched hypoglycemic-functional bacteria, such as Bacteroides and Alloprevotella. These bacteria feedback-regulated the production of hypoglycemic polyphenolic substances such as isovitexin and isoquercetin, which showed a strong positive correlation. Further mechanistic studies revealed that FPPE's digest could suppress cellular glucose transport by inhibiting the expression of Sodium Glucose Cotransporter 1 (SGLT1) and glucose transporter 2 (GLUT2), thereby reducing blood glucose levels.\n\nID: 42435608\nTitle: Yolk metabolomics reveals candidate compounds associated with egg specific density and hatchability in white layer breeder hens.\nAbstract: The present study aimed to evaluate the influence of egg geometry, weight loss, and specific density (SD) on hatchability in older white layer breeder hens. In addition, based on the positive correlation observed between fertility and egg SD, we hypothesized that the mineral and metabolomic composition of the yolk may be associated with specific density. A total of 8,874 eggs from five Lohmann LSL Lite breeder flocks (52-64 weeks) were analyzed. We found that digital image analysis is an adequate method for evaluating the egg shape index, whereas Archimedes' principle is suitable for determining SD. Although we observed an influence of shape index and weight loss on hatchability, the clearest findings were related to SD. Eggs within the upper 50% SD range (1075-1110g/L) exhibited higher hatchability than those with lower SD, primarily due to reduced infertility and lower early embryonic mortality. Low-SD eggs showed increased contamination rates. Yolk mineral concentrations did not differ significantly between SD groups, except for the Na:K ratio. However, the N;Ka ratio showed minimal predictive value, indicating that mineral composition alone has limited explanatory power for eggshell density. Untargeted metabolomics identified 310 metabolites in yolk, but only melatonin glucuronide and dihydroxytetradecanoic acid met the significance criteria (p<0.05; fold change > 2). This study provides a precise way to evaluate egg geometry and SD. Furthermore, using a large dataset, it demonstrates that eggs with low SD have reduced hatchability due to infertility and early mortality, likely linked to contamination. Although the Na:K ratio, melatonin glucuronide, and dihydroxytetradecanoic acid showed limited predictive performance when evaluated individually, their identification highlights potential biochemical differences associated with SD and supports their further investigation as candidate markers.\n\nID: 42435543\nTitle: Non-targeted metabolomics reveals differential distribution of flavonoids and organic acids between mesophyll and vein tissues in Synotis solidaginea leaves with AFADESI-MSI confirmation.\nAbstract: Synotis solidaginea Hand.-Mazz. (SSD), a traditional Tibetan medicinal plant utilized for heat-clearing and wound healing, contains organic acids and flavonoids as primary bioactive components. This study aimed to investigate the differential distribution of flavonoids and organic acids between mesophyll and vein tissues in SSD leaves using non-targeted metabolomics with AFADESI-MSI confirmation. Non-targeted metabolomics using ultra-performance liquid chromatography-quadrupole Exactive HF-X (UPLC-Q Exactive™ HF-X) was employed to analyze chemical composition differences between mesophyll (YR) and vein (YM) tissues. Flavonoids and organic acids were analyzed separately as key compound classes. Air flow-assisted desorption electrospray ionization mass spectrometry imaging (AFADESI-MSI) was used to confirm and visualize the spatial distribution of representative metabolites. Multivariate statistical analyses including principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA) were performed to identify tissue-specific signatures. The non-targeted metabolomics analysis identified a total of 2984 metabolites, among which 899 exhibited significant differential accumulation between the two tissue types. Organic acids and their derivatives constituted the largest proportion (50.7%) of these differential metabolites. Specifically, the bioactive flavonoids quercetin and gossypetin showed a 7.8-fold higher accumulation in the veins, whereas homoeriodictyol exhibited a 10.22-fold enrichment in the mesophyll. Regarding organic acids, gallic acid C was highly concentrated in the mesophyll (37.65-fold higher), whereas 4-hydroxycinnamic acid and maleic acid were significantly enriched in the veins. Crucially, AFADESI-MSI successfully confirmed the highly compartmentalized spatial distribution patterns of 14 key metabolites. This study revealed distinct tissue-specific distribution patterns of flavonoids and organic acids in SSD leaves. The combination of non-targeted metabolomics with AFADESI-MSI confirmation provides a robust analytical framework for understanding chemical distribution in traditional medicinal plants, offering insights for quality control and targeted extraction strategies.\n\nID: 42435492\nTitle: Toxicological evaluation of benzophenone-3 and its metabolite benzophenone-1 in TM3 Leydig cells.\nAbstract: Recently, a decline in male fertility has been reported, raising concerns about the role of environmental pollutants. Ultraviolet (UV) filters have attracted attention due to their potential effects. Benzophenone-3 (BP-3) is a widely used UV filter. It is frequently detected in environmental and human biomonitoring studies, indicating widespread exposure. After dermal absorption, BP-3 enters systemic circulation and is metabolized to benzophenone-1 (BP-1). Although both compounds have been reported to exhibit endocrine-active properties, including antiandrogenic effects, toxicological data on BP-1 are still limited. Therefore, the potential effects of benzophenone derivatives on Leydig cell function and male reproductive health require further investigation. We aimed to evaluate the potential cytotoxic and genotoxic effects of BP-3 and BP-1 in TM3 mouse Leydig cells. Cytotoxicity was assessed using the MTT (3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide) and neutral red uptake assays. DNA damage was evaluated using the alkaline comet assay. Reactive oxygen species (ROS) production was determined using a DCFDA/H2DCFDA-based assay, and testosterone levels were measured using an enzyme-linked immunosorbent assay (ELISA). Exposure to both compounds resulted in concentration-dependent reductions in cell viability, with a more pronounced decrease for BP-1. BP-1 increased ROS formation at selected concentrations, whereas BP-3 did not induce oxidative response. Assessment of DNA integrity using the comet assay did not reveal measurable DNA damage. Under experimental conditions without hormonal stimulation, no statistically significant difference in testosterone concentrations was observed. The findings indicate BP-1 may exert stronger cytotoxic and oxidative effects than BP-3 in Leydig cells, suggesting that metabolites may contribute to the overall toxicological profile of UV filters in reproductive toxicity evaluations.\n\nID: 42435486\nTitle: Metabolite-driven epigenetic modifications remodel immune cell functions in COPD: From Lactylation to Succinylation.\nAbstract: Chronic obstructive pulmonary disease (COPD) is characterized by persistent airway inflammation, progressive immune dysfunction, and irreversible structural remodeling. Although cigarette smoke-induced oxidative stress has long been recognized as the predominant pathogenic driver, conventional inflammatory theories fail to fully account for the sustained inflammatory state that persists even after smoking cessation. Accumulating evidence indicates that COPD is governed by a metabolite-centered epigenetic regulatory network. Intracellular metabolic intermediates function not only as substrates for energy metabolism, but also as signaling molecules that directly modulate chromatin architecture and transcriptional programs. In this context, metabolic reprogramming emerges as a pivotal determinant of immune cell fate and inflammatory memory formation. This review systematically summarizes recent research advances in the \"metabolite-redox-epigenetics\" axis in COPD. We specifically discuss histone lactylation as a glycolysis-dependent inflammatory amplification mechanism and propose that histone succinylation represents a redox-sensitive epigenetic mechanism linked to mitochondrial dysfunction, bridging tricarboxylic acid (TCA) cycle dysregulation and persistent immune activation. We further integrate acetylation, crotonylation, β-hydroxybutyrylation, DNA methylation, and RNA m6A modification to construct a unified immunometabolic regulatory network. We propose that COPD is essentially a metabolically imprinted inflammatory memory disease, whose core mechanism resides in the chronic oxidative stress-triggered persistent remodeling of chromatin accessibility, which stably enforces pathogenic immune phenotypes. Targeting metabolite-driven epigenetic remodeling may offer novel therapeutic strategies to reverse chronic inflammatory memory and restore immune homeostasis. Recent evidence further suggests that cGAS-STING-mediated mitochondrial DNA sensing, inflammasome-dependent pyroptosis, gut-lung axis-derived metabolites, and AMPK/SIRT1/PGC-1α signaling may provide additional links between metabolic stress, epithelial injury, and immune dysfunction.\n\nID: 42435434\nTitle: Molecular networking-guided discovery of cytotoxic metabolites in Humiria balsamifera: insights into Bergenin selectivity and safety.\nAbstract: This study investigated the chemical composition and cytotoxic activity of Humiria balsamifera St. (Aubl.) Hill. Extracts obtained with ethyl acetate, methanol, and ethanol were analysed by UHPLC-QTOF-MS molecular networking, and statistical analysis, revealing 18 metabolites in positive mode. Multivariate analyses showed that plant organ and extraction solvent strongly shaped metabolite profiles, identifying bioactive markers with biological relevance. Bergenin was isolated from the ethyl acetate extract of the stem. The in vitro cytotoxicity screening in human colorectal carcinoma cells (HCT-116) demonstrated that the isolated compounds exhibited inhibition greater than 75%, while the crude extracts were less effective. Bergenin, also evaluated in mammary adenocarcinoma cell lines (MCF-7 and MDAMB231) and non-tumour cells (RPE-1), did not inhibit the growth of cancer cells but showed low toxicity in healthy cells. The analysis of the identified metabolites suggests the potential of the species as a source of bioactive compounds. The selectivity of the antiproliferative effect of the isolates in HCT-116 and the safety of bergenin in non-tumour cells indicate the need for future investigations to elucidate their mechanisms of action and explore their therapeutic potential, as well as to identify other relevant compounds.\n\nID: 42435267\nTitle: A metabolomic signatures in hyperuricemia: a systematic review.\nAbstract: Hyperuricemia (HUA) is traditionally viewed as a disorder of purine metabolism. However, its broader metabolic alterations remain incompletely understood. Metabolomics provides a useful approach for exploring metabolite changes associated with HUA, but a comprehensive synthesis of existing findings is still lacking. This systematic review and meta-analysis aimed to characterize the systemic metabolic signature of HUA beyond purine pathways. By synthesizing data from 27 metabolomics studies involving 12,335 participants, the study sought to identify consistent metabolite biomarkers and key dysregulated pathways to provide new insights for diagnosis and therapeutic targeting. This review included 27 metabolomics studies involving 12,335 participants and identified 1,187 metabolites reported in association with HUA. Qualitative synthesis showed 54 consistently elevated and 20 consistently decreased blood metabolites, mainly involving amino acids, lipid-related metabolites, energy-related compounds, vitamins and their derivatives, and purine nucleoside metabolites. The meta-analysis was limited to two eligible studies, with one study contributing most of the statistical weight; it suggested higher levels of Alanine, Leucine, Phenylalanine, and Tyrosine and lower Histidine levels in HUA. Pathway enrichment analysis highlighted \"One carbon pool by folate,\" \"Arginine biosynthesis,\" \"Glutathione metabolism,\" and related amino acid and energy metabolism pathways. Overall, these findings suggest that HUA may be associated with metabolic perturbations beyond purine metabolism alone, but the candidate metabolites and pathways require further validation in longitudinal, standardized, and mechanistic studies.\n\nID: 42435238\nTitle: A machine learning approach to metabolomics identifies putative biomarker candidates and dysregulated pathways for distinguishing gout from asymptomatic hyperuricemia in the Zhuang population.\nAbstract: Gout typically develops from hyperuricemia (HUA), but the metabolic alterations driving this transition remain poorly understood, limiting our understanding of disease pathogenesis. To identify stage-specific putative biomarker candidates and to characterize dysregulated metabolic pathways distinguishing gout from HUA. We conducted a targeted metabolomics assay on the baseline plasma samples from a Zhuang minority cohort using LC-MS/MS. The analyzed sample set comprised 38 HUA patients, 47 gout patients, and 52 healthy controls. Sex-stratified differential metabolite analysis was performed across all participants, as well as in female and male subgroups. Pathway enrichment analysis was carried out using the KEGG database. Machine learning approaches, including the Boruta algorithm and support vector machine (SVM), were employed for putative biomarker discovery and model evaluation in male participants. Among all participants, 24 metabolites reached nominal significance (P < 0.05), but only uric acid remained significant after FDR correction. In sex-stratified analyses, no metabolite survived FDR correction in females, whereas in males, seven metabolites (flavone, glutamine, L-2-aminoadipic acid, L-pipecolic acid, N1-methyl-2-pyridone-5-carboxamide, phenyllactic acid, and uric acid) showed significant differences among healthy controls, HUA patients, and gout patients (FDR < 0.1). These metabolites were primarily involved in nitrogen metabolism, arginine biosynthesis, D-amino acid metabolism, nicotinate and nicotinamide metabolism, and purine metabolism. Machine learning identified four metabolites (N1-methyl-2-pyridone-5-carboxamide, flavone, glutamine, and phenyllactic acid) that distinguished gout from healthy controls, with AUCs of 0.902 and 0.800 in the training and validation sets, respectively. A second model (L-pipecolic acid, glutamine, phenyllactic acid, and flavone) discriminated gout from HUA, achieving AUCs of 0.850 and 1.000. Sensitivity analyses excluding obese or hypertriglyceridemic participants confirmed the robust performance of both models. This study suggests sex-specific metabolic alterations in gout and provides robust machine learning-based models for male participants. The identified metabolite signatures appear to extend purine metabolism to involve amino acid and energy metabolic pathways. These findings provide a basis for mechanism-targeted strategies in HUA management. External validation remains essential.\n\nID: 42435223\nTitle: Back to the roots: Cannabis sativa L. root metabolism, microbiomes, and biotechnological potential.\nAbstract: Cannabis sativa L. roots have been less studied than aboveground organs, despite their key role in plant physiology, metabolism, and interactions with biotic and abiotic factors. Metabolomic and phytochemical analyses reveal that roots synthesize a diverse array of bioactive compounds with antimicrobial, anti-inflammatory, antioxidant, and cytotoxic properties, highlighting their biotechnological potential. Root exudation patterns and interactions with endophytic microorganisms modulate rhizosphere microbial networks that support nutrient uptake, stress tolerance, pathogen resistance, and whole-plant physiology. Root-derived phytohormones and other signalling molecules may participate in coordinating biochemical pathways between belowground and aboveground tissues, with potential effects on secondary metabolism in aerial tissues. Recent advances in metabolomics, transcriptomics, microfluidic rhizosphere systems, and root-specific genetic engineering now enable detailed investigation of root metabolism in Cannabis sativa L. This review synthesises current knowledge on the metabolic roles of Cannabis sativa L. roots, their interactions with the rhizosphere microbiome, and root-derived systemic signalling. It emphasises aspects of root biology that are central to fundamental plant processes and to the development of sustainable strategies for optimising phytochemical yields. By placing roots at the forefront, this synthesis underscores the need to expand research beyond aerial tissues to fully understand and harness the biotechnological potential of Cannabis species. KEY POINTS: • Root metabolism and signalling regulate whole-plant-metabolic pathways • Root-associated microbiomes influence nutrient dynamics and phytochemical profiles • Root culture systems provide a scalable platform for biotechnological manipulation aimed at the production of bioactive compounds.\n\nID: 42435219\nTitle: The slow component of the [Formula: see text] response is associated with the increase in glycolytic contribution.\nAbstract: After approximately 2 min of severe intensity exercise, there is a delayed increase in oxygen uptake (V̇O2). It has been hypothesized that this slow component may be in response to an increase in glycolytic contribution, which causes a progressive recruitment of less-efficient Type II fibers. We examined whether the area under the curve of the V̇O2 slow component (AUCslow) is associated with glycolytic contribution during severe intensity constant-power cycling. Seven women and 13 men completed three constant-power cycle tests terminated at 3, 6, or 9 min in randomized order. The kinetics of the V̇O2 response was modelled using iterative regression, and AUCslow was calculated. Glycolysis contribution was estimated from peak post-exercise blood lactate. Pearson correlations assessed associations at each duration. AUCslow was 2 ± 1 mL·kg⁻1 in 0-3 min of exercise; there was an additional 8 ± 3 mL·kg⁻1 in min 3-6 and an additional 4 ± 3 mL·kg⁻1 in min 6-9. Glycolysis contribution was 18 ± 7 mL·kg⁻1 in min 0-3, an additional 6 ± 2 mL·kg⁻1 in min 3-6, and an additional 2 ± 1 mL·kg⁻1 in min 6-9. Correlation values for AUCslow and glycolytic contribution were strong (r = 0.69, p < 0.01 for 3-6 min; and r = 0.75, p < 0.01 for 6-9 min). AUCslow is related to glycolytic contribution after 3 min of severe intensity exercise. We speculate this is due to an increase in Type II fiber recruitment to compensate for fatiguing active fibers due to the accumulation of glycolytic metabolites.\n\nID: 42435173\nTitle: Epigenetics and One-Carbon Metabolism in Cancer: Mechanisms and Therapeutic Implications.\nAbstract: Epigenetics refers to heritable changes in gene expression that occur without alterations in the DNA sequence itself, primarily through mechanisms such as DNA methylation and histone modifications. These regulatory processes are essential for normal development, cellular differentiation, and genome stability. In cancer, however, epigenetic reprogramming becomes dysregulated, contributing to tumor initiation, progression, and metastasis. Aberrant DNA methylation patterns and histone modifications can silence tumor suppressor genes or activate oncogenes, driving malignant transformation. Central to these epigenetic processes is one-carbon metabolism-a biochemical network that supplies methyl groups for DNA and histone methylation through metabolites such as S-adenosylmethionine (SAM). As such, the interplay between one-carbon metabolism and epigenetic regulation is a critical axis in understanding and potentially targeting cancer biology.\n\nID: 42435167\nTitle: Metabolism-Driven Modulation by the Human Microbiota: Implications for Cancer Therapy and Emerging Strategies.\nAbstract: The human microbiome plays a pivotal role in cancer development, progression, and therapeutic response. Epidemiologic studies have established links between microbiome composition and various malignancies, with specific microbial taxa exerting direct carcinogenic effects or influencing tumorigenesis through metabolite production and immune modulation. While the gut microbiome remains the most extensively studied, emerging evidence highlights the significance of microbiomes in other body sites, including the cervix, lung, and skin, which also modulate cancer risk and progression. These site-specific microbial communities interact with local factors, such as human papillomavirus in the cervix or inflammatory pathways in the lung and skin, contributing to carcinogenesis. Importantly, distinct microbial signatures across these niches serve as promising noninvasive biomarkers for early cancer detection and prognosis, offering improved accessibility and patient compliance compared to traditional methods. Additionally, the gut microbiome influences anticancer therapeutic outcomes, suggesting that metabolism-based interventions targeting microbial-host interactions may enhance treatment efficacy. Integrating microbiome research into oncology presents novel opportunities for advancing personalized cancer prevention, diagnosis, and therapy.\n\nID: 42435165\nTitle: The Interdependence of Carbon Substrates and Metabolic Pathways Enables the Metabolic Plasticity of Cancer Cells.\nAbstract: The tumor microenvironment (TME) functions as a dynamic and co-evolving ecosystem, where malignant and non-malignant cells form a metabolically interdependent community. This ecological view reimagines tumors not as isolated cell masses, but as complex biotopes in which cellular interactions are integral to tumor initiation, growth, and progression. A hallmark of this adaptive environment is metabolic plasticity-an essential mechanism that enables tumor cells, including the metastatic ones, to reprogram their metabolism in response to fluctuating nutrient availability and environmental stressors. At the core of this reprogramming lies carbon metabolism, characterized by the selective and flexible utilization of key metabolites, including glucose, lactate, glutamine, cysteine, and fatty acids. These compounds support energy production, biomass synthesis, and redox balance, while also facilitating the export and repurposing of metabolic byproducts for signaling or reuse. This chapter presents a conceptual framework that explores the interdependence of central metabolic pathways, emphasizing how tumors coordinate energy generation, biosynthesis, and redox control to support malignant progression.\n\nID: 42435073\nTitle: SigMine and OPathDb: a literature-mining pipeline and database of potential opportunistic pathogens.\nAbstract: Conversion of unstructured biomedical literature into structured knowledge for identifying cross-domain associations between biological entities remains a challenging task. SigMine is an automated pipeline constructed to mine biomedical literature to identify significantly associated biological entities. SigMine performs biomedical entity recognition from PMC articles using the EuropePMC Annotation API. Advanced entity recognition was performed using Python scripting, NCBI E-Utilities, and an n-gram algorithm followed by extensive data cleaning and mapping against standard databases. Statistical evaluation identified significantly co-occurring entities. The entire workflow was automated through a modular framework developed in Python v3.13 with a Tkinter-based Graphical User Interface. SigMine enhances usability while retaining the flexibility to use new dictionaries for annotation. SigMine was used to construct a literature-derived potential human Opportunistic Pathogens Database (OPathDb), housing 5,626 potential opportunistic pathogens significantly co-occurring with 1440 diseases and 7121 genes mined from 25,000 PMC articles. Additional annotation of 598 significantly co-occurring metabolites and 30 affected tissues is available for 3204 and 227 pathogens, respectively. OpathDb has a user-friendly query interface searchable by organism, disease, tissue, gene, protein and metabolite available at https://www.opathdb.cbsblab-nsut.in . Organism-entity associations can be visualized as weighted networks, with color-coded nodes and significance-scaled edges. Significant associations of opportunistic pathogens like Akkermansia mucinifila with colorectal cancer and Segatella copri with glucose intolerance can be identified through OpathDb. Through this database, the SigMine framework demonstrates conversion of unstructured text in vast and heterogenous corpora into standardized and well-organized information. Statistically inferred associations in OPathDb are potential candidates for clinical and experimental validation.\n\nID: 42435068\nTitle: Tandem-sgRNA Provides an Effective Reverse Genetic Approach for Suppression of Streptomyces Biosynthetic Gene Clusters and Secondary Metabolism.\nAbstract: Bacterial biosynthetic gene clusters (BGCs) encode secondary metabolites with diverse biological activities; however, most BGC products remain uncharacterized. One approach to identifying products and their metabolism is to use reverse genetics to identify metabolite-associated phenotypes. CRISPR interference (CRISPRi) offers a promising approach to disrupt BGC functions in high-GC genomes, typical of Streptomyces species. In many of these organisms, single-guide RNA (sgRNA)-mediated CRISPRi often results in incomplete product suppression, resulting in partial phenotypes that are unsuitable for functional studies. Using Streptomyces sp. Mg1, we found that a tandem-sgRNA configuration for CRISPRi improved the efficiency of target metabolite suppression. We engineered strains to express two sgRNAs to target the same promoter region within a BGC, resulting in greater than 80% metabolite suppression across diverse secondary metabolite classes. We used tandem-sgRNA CRISPRi to identify phenotypes associated with the loss of polyketide linearmycins, the siderophore desferrioxamine, the terpene β-carotene, and an uncharacterized nonribosomal peptide synthetase (NRPS). This approach revealed that β-carotene depletion substantially reduced intrinsic cellular autofluorescence. Targeting the unknown NRPS produced developmental phenotypes and enabled the identification of the biosynthetic genes for the antibiotic lavendomycin, revealing a noncollinear organization of genes in the BGC. We suggest that tandem-sgRNA CRISPRi provides an efficient reverse genetics platform for the functional characterization of Streptomyces BGCs, enabling the correlation of metabolites with the gene function, identification of associated phenotypes, and prioritization of cryptic BGCs for natural product discovery.\n\nID: 42434881\nTitle: Synergistic effects of chitin and nitric oxide on phytochemical and molecular defense mechanisms in Andrographis paniculata under nickel stress.\nAbstract: Nickel (Ni) contamination is an increasing environmental concern that negatively affects plant growth, physiological performance, and the biosynthesis of medicinally important secondary metabolites. The use of natural biostimulants such as chitin and nitric oxide (NO) has emerged as a promising strategy to enhance plant tolerance against heavy metal stress. Therefore, this study investigated the potential of chitin and NO to enhance the physiological and phytochemical responses of Andrographis paniculata under Ni stress. The study was designed to assess the effects of varying concentrations of chitin (0, 15, and 30 µM) and NO (0, 0.5, and 1 g/L) on several growth parameters, including photosynthetic pigments, total phenolic content, total flavonoid content, protein accumulation, key secondary metabolites (andrographolide, neoandrographolide, and 14-deoxy-11,12-didehydroandrographolide), and the expression of isoprenoid biosynthesis-related genes (HMGR, HMGS, DXR, and DXS) in A. paniculata under different levels of Ni stress (0, 1.5, and 3 mM). The results showed that Ni stress significantly reduced chlorophyll, carotenoid, phenolic, and protein contents, whereas it altered secondary metabolite profiles and gene expression patterns. Application of NO and chitin significantly improved chlorophyll a, chlorophyll b, carotenoids, total phenols, and protein content under Ni stress conditions. In addition, NO and chitin treatments enhanced the accumulation of key bioactive compounds and positively regulated the expression of genes involved in terpenoid biosynthesis pathways. Overall, the findings indicate that NO and chitin alleviate Ni-induced stress in A. paniculata primarily through improving physiological performance and enhancing the accumulation of non-enzymatic antioxidant compounds such as phenolics and flavonoids, thereby contributing to improved metabolic stability and secondary metabolite production under heavy metal stress. Andrographis paniculata emerges as a valuable medicinal-industrial species with diverse pharmaceutical applicationsChitin-nitric oxide synergy significantly boosts nickel stress tolerance and phytochemical production in A. paniculataNickel stress upregulates terpenoid biosynthesis genes (HMGS, HMGR, DXS, DXR), amplified by chitin-NO elicitation.\n\nID: 42434567\nTitle: Multi-omics reveal soil microbial dysbiosis and metabolite toxicity as drivers of blueberry continuous cropping obstacles.\nAbstract: Blueberry (Vaccinium spp.) are one of the most economically important fruit trees globally. However, due to continuous cropping have limited the industry's ability to produce consistently over the long term, and the mechanism underlying the development of this continuous cropping problem is not yet fully understood. In this study, we applied metagenomic and metabolomic to systematically detect changes in microbial community structure, function and metabolic profiles in rhizosphere and non-rhizosphere soils after different years of continuous blueberry cultivation (0, 2, 4, and 6 years) in Dalian (China). The results showed that continuous cultivation significantly reduced overall microbial diversity and the bacterial and fungal Shannon index, with the decrease being more significant in the rhizosphere soils (P < 0.05). The β diversity analysis showed that the microbial community structure was distinctly separated between cultivation periods, with the most prominent differences in the rhizosphere soils (PERMANOVA, P < 0.01). The increased cultivation duration led to a decrease in the relative abundance of beneficial functional taxa in the microbial community, while the depletion-tolerant and stress-adapted taxa were gradually enriched. Functional annotation analysis showed that KEGG pathways related to stress response, amino acid degradation, and energy metabolism significantly increased, while functions related to nutrient transformation and plant-microbe interactions were weakened (FDR < 0.05). The metabolomic results further showed that 6 years of continuous cultivation significantly reshaped the rhizosphere metabolite composition. This was evidenced by the accumulation of various secondary metabolites in the rhizosphere soil, including metabolites related to potential self-toxicity (e.g., ferulic acid, 3-hydroxyphenylacetic acid, and 2-hydroxycinnamic acid), mainly involved in the pathways of amino acid metabolism, lipid metabolism, and secondary metabolite synthesis. In conclusion, continuous cultivation of blueberry induced pronounced shifts in rhizosphere microbial community structure, function, and metabolite composition, suggesting that these changes may contribute to the development of continuous cropping obstacles (CCO).\n\nID: 42434505\nTitle: Metabolomic data of melittin-intervened murine cervical cancer cells based on liquid chromatography-mass spectrometry.\nAbstract: Melittin-treated murine cervical cancer U14 cells have been widely recognized as a classic cellular model for anti-tumor research in cervical cancer. This article contains metabolomic data of U14 cell lysates from both melittin-treated and control groups. Untargeted metabolomic profiling was carried out by liquid chromatography-mass spectrometry (LC-MS) to systematically elucidate the global metabolic disturbances in cervical cancer cells upon melittin intervention. LC-MS raw data were processed for peak extraction and alignment using XCMS software, followed by quality control normalization with metaX software. Metabolite annotation was performed against the HMDB and KEGG databases as well as an in-house MS/MS spectral library, yielding metabolite feature data including mass-to-charge ratio (m/z), retention time (RT), and MS/MS-identified metabolites (MS2). A total of 22,976 metabolic ions were detected in this study, among which 16,176 were assigned Level 1 annotations and 1114 were identified with high confidence at Level 2. All raw and processed data are publicly accessible at NGDC (accession number PRJCA065444). This untargeted LC-MS-based metabolomic dataset not only provides a comprehensive resource for elucidating metabolism-related anticancer mechanisms of melittin in murine U14 cervical cancer cells but also supports the development of targeted therapeutic strategies against cervical cancer.\n\nID: 42434393\nTitle: Metabolomic and Metagenomic Correlation Reveals the Network Regulatory Mechanism of Cecal Microbiota Structural Changes Induced by Eimeria tenella.\nAbstract: Eimeria tenella poses a significant threat to the poultry industry, and understanding the correlation between metabolic changes in cecal tissues and microbial community alterations is crucial for studying parasite-host interactions. To investigate the associations among dominant bacterial populations, key functional genes, and altered metabolites in cecal tissues and contents during E. tenella infection. Metagenomic analysis was first performed on cecal contents to identify the dominant bacterial communities, followed by metabolomic analysis of cecal tissues and contents. Correlation analysis was then conducted to evaluate the relationships among microbial communities, functional genes, and differential metabolites. Correlation analysis showed that increased potentially pathogenic genera were generally positively associated with upregulated metabolites and negatively associated with downregulated metabolites, whereas reduced commensal genera showed the opposite trend. Shared KEGG pathways co-enriched by differential metabolites and microbial functional genes were identified, mainly involving amino acid metabolism, transport systems, membrane-associated metabolism, and nucleotide metabolism. The metabolites linked to dominant bacterial communities were primarily enriched in pathways such as amino sugar metabolism, sialic acid metabolism, and glycerophospholipid metabolism. These findings reflected complex metabolic reprogramming and interactions between the host and pathogen, especially in cecal tissue repair, immune regulation, and metabolic competition with the pathogen. This study provided valuable insights into parasite-host interactions and laid a foundation for understanding the role of bacterial community-associated metabolites in cecal coccidiosis.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson’s complementary-but-disjoint (A-B-C) model.

We investigated the therapeutic efficacy of the sialidase inhibitor (SI) in UC. In a pilot randomized clinical trial, SI intervention significantly improved clinical symptoms and endoscopic outcomes in mild-to-moderate UC patients. This improvement correlated with an enrichment of butyrate-producing taxa and beneficial metabolic pathways. In a dextran sulfate sodium-induced colitis mouse model, SI attenuated inflammation and restored mucus layer integrity, accompanied by increased expression of Muc2 and Tff3. Crucially, unlike broad-spectrum antibiotics, SI preserved microbial community resilience while specifically enriching beneficial mucolytic commensals, Akkermansia muciniphila and Bacteroides acidifaciens. These findings identify SI as a promising therapeutic strategy that targets sialidase activity to reinforce the mucosal barrier and restore gut homeostasis.IMPORTANCEThe gut microbiota plays a pivotal role in maintaining mucosal integrity and intestinal homeostasis; however, dysbiosis-driven mucus layer degradation remains a hallmark of ulcerative colitis (UC). Current interventions like antibiotics often disrupt microbial diversity, exacerbating dysbiosis and failing to address mucosal thinning, which is a critical factor in UC progression. Developing strategies to reinforce the mucus barrier without compromising microbial balance is urgently needed, but such approaches remain underexplored. Our study demonstrates that sialidase inhibitors (SIs) uniquely preserve mucosal thickness by curbing microbial mucin degradation while selectively enriching beneficial taxa and butyrate-producing bacteria. Unlike antibiotics, SIs enhance mucosal protection without destabilizing microbial communities, offering a dual-action therapeutic strategy. This work bridges a critical knowledge gap, providing evidence for microbiota-targeted therapies that synergistically restore mucosal health and microbial ecology in UC.CLINICAL TRIALSThis study was registered with the Chinese Clinial Trial Registry as ChiCTR2000028767.\n  --- END ACTUAL ABSTRACT FOR 42429666 ---\n\n\n✅ PASSED (DO NOT CHANGE THESE):\n- \"Targeting the coordinated interplay among diet, microbiota, metabolism, immunity, and the hepatic spatial niche may help intercept chronic liver disease before malignant transformation\" (Source: 42429613)\n- \"dietary BAs can attenuate these detrimental effects by modulating metabolic pathways and the gut microbiota composition.\" (Source: 42415055)\n- \"Activation of FXR has emerged as a promising therapeutic strategy for treating metabolic dysfunction-associated steatohepatitis (MASH) or other FXR-dependent diseases.\" (Source: 42421220)\n- \"GRE administration effectively prevented the decrease in the gut microbial richness and diversity caused by WD and recovered serum branched-chain amino acids and microbiota-derived purine metabolites\" (Source: 42436161)\n- \"The MT is associated with a rise in markers of compromised gut barrier integrity, suggesting that this pathway of inflammation, previously described in animal models, occurs in humans.\" (Source: 42424108)\n- \"Rifaximin treatment selectively reduces O.splanchnicus and plasma PAA, thereby alleviating aging-related anemia.\" (Source: 42430365)\n- \"These findings suggest that habitual cannabis use may protect gut barrier integrity and reduce microbial translocation and associated inflammation\" (Source: 42427618)\n- \"Supplementation with MI ameliorated neural damage, cerebral edema, and neuronal loss in an intake dose-responsive manner, enhanced intestinal barrier integrity\" (Source: 42435878)\n- \"Gut barrier integrity was enhanced, as evidenced by significantly increased expression of tight junction proteins, zonula occludens-1 (ZO-1) and claudin-2 concentrations\" (Source: 42404072)\n- \"We propose that COPD is essentially a metabolically imprinted inflammatory memory disease, whose core mechanism resides in the chronic oxidative stress-triggered persistent remodeling of chromatin accessibility\" (Source: 42435486)\n- \"UroA treatment protected hAS3MT mice from iAs-induced gut permeability, inflammation, colon shortening, and elevated colon weight/length ratio.\" (Source: 42400257)\n- \"CDCA, a primary bile acid activating FXR signalling, is a novel pharmacological strategy to mitigate post-SVR ferroptosis and improve cardiac outcomes.\" (Source: 42427128)\n- \"Integrating microbiome research into oncology presents novel opportunities for advancing personalized cancer prevention, diagnosis, and therapy.\" (Source: 42435167)\n- \"beneficial microbial taxa, including Akkermansia muciniphila, Bifidobacterium longum, and Parabacteroides distasonis, enhance liver regeneration by regulating short-chain fatty acid production\" (Source: 42423485)\n- \"These findings suggest that hesperidin, nanohesperidin, and OCA may influence fibrosis-related pathways in experimental MASLD, possibly through modulation of FXR and SMAD3 signaling.\" (Source: 42420514)\n- \"microbiota dysbiosis and metabolite alterations functionally increase vulnerability to stroke injury, highlighting the gut microbiome as a potential target for risk stratification\" (Source: 42429658)\n- \"Compared with the CS & CsA-sensitive PIU patients, serum samples from CS & CsA-resistant PIU patients displayed significant metabolic reprogramming.\" (Source: 42435811)\n- \"Metabolomic profiling detected 1,589 putative metabolites, revealing differential enrichment of lipid, amino acid, and bile acid metabolic pathways between fast- and slow-growing goats.\" (Source: 42436575)\n- \"the gut microbiome provides a key interface for these processes by integrating both chemical and physical cues from foods after ingestion\" (Source: 42436035)\n\n\nINSTRUCTION: Study the actual abstracts provided.

Treatment strategies targeting liver-centric receptors, specifically the Farnesoid X Receptor (FXR), demonstrate a bidirectional capacity to attenuate hepatic steatosis and inflammation while concurrently restoring intestinal homeostasis. This synthesis investigates whether clinical and pharmacological interventions for fatty liver disease effectively reverse intestinal barrier dysfunction.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe pathophysiology of MASLD involves complex multi-organ communication, where hepatocyte lipotoxicity and altered bile acid (BA) signaling exacerbate systemic metabolic dysfunction. Therapeutic agents designed to restore hepatic health, particularly FXR agonists, act as systemic regulators. By modulating the enterohepatic circulation of bile acids, these agents alleviate metabolic hepatic stress and concomitantly improve intestinal epithelial barrier integrity. Current evidence indicates that targeting the \"synthesis-transport-signaling\" axis of bile acids is a viable strategy to reverse the systemic consequences of liver-gut crosstalk, thereby addressing the \"leaky gut\" phenotypes frequently observed in metabolic syndrome.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   FXR activation is not merely a liver-centric pathway; it acts as a central hub regulating intestinal barrier integrity and inflammation.\n*   Certain Bile Acids (BAs) modulate intestinal TGR5 signaling, providing an alternate pathway for suppressing gluconeogenic enzymes and restoring gut mucosal health.\n*   Intestinal FXR-deficiency can actually protect against steatosis while paradoxically failing to prevent MASH-associated liver inflammation, highlighting the \"therapeutic tension\" in targeting individual receptors.\n*   Dietary polysaccharides can remodel the microbiota to increase short-chain fatty acid (SCFA) production, which serves as a cross-talk mechanism to improve both liver lipid storage and intestinal mucosal barrier function.\n*   Nano-formulations of herbal extracts (e.g., nanohesperidin) provide superior FXR-activation profiles compared to non-targeted formulations, suggesting that pharmacokinetics determines the efficacy of gut-liver axis restoration.\n*   The gut-liver axis is susceptible to antibiotic-induced dysbiosis, which can undermine the efficacy of liver-directed therapies by collapsing the microbial ecosystem responsible for metabolite production.\n*   Metabolic Dysfunction-Associated Fatty Liver Disease (MAFLD) progression involves a heterogeneous continuum of microbial remodeling that must be addressed alongside host-centric pharmacological intervention to prevent progression to hepatocellular carcinoma.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Herbal medicines offer multi-component therapeutic potential through microbiota modulation, but mechanistic insights remain fragmented. This review synthesizes recent advances in herbal medicine-mediated gut microbiota regulation in metabolic diseases and delineates underlying molecular mechanisms. A comprehensive literature search was conducted across PubMed and Web of Science. Search strategies employed MeSH terms and free-text keywords encompassing herbal medicines, gut microbiota, and metabolic diseases. Two authors performed study selection and data extraction. Evidence synthesis was structured according to intervention type and metabolic disease category. Herbal polysaccharides and other compounds consistently increased beneficial bacteria and promoted short-chain fatty acids (SCFAs) production, improving intestinal barrier integrity via ZO-1/Occludin upregulation and attenuating TLR4/NF-κB-mediated inflammation. Herbal formulations exerted synergistic effects by remodeling microbial community structure, correcting SCFA/bile acid imbalances, and activating IRS1/PI3K/AKT insulin signaling. Notably, Lactobacillus and Akkermansia emerged as recurrent beneficial targets across multiple herbal interventions. However, evidence is predominantly preclinical, and translational validity to humans requires further validation. Herbal medicines ameliorate metabolic diseases through multi-target gut microbiota modulation, involving SCFA production, bile acid metabolism, and inflammatory pathway attenuation. These mechanistic insights support the development of microbiota-targeted herbal therapeutics, though clinical translation necessitates standardized formulations and rigorous human trials."},{"quote":"PVP and RA significantly alleviated hepatic lipid accumulation in HepG2 cells, inhibited intestinal cholesterol absorption, and promoted cholesterol efflux in Caco-2 monolayers.","source_id":"42428305","status":"PASS","error":"","abstract_text":"ID: 42428305\nTitle: Prunella vulgaris polyphenols mediate the gut-liver axis to improve MASLD: regulating cholesterol metabolism and gut microbiota.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most prevalent chronic liver disease worldwide. The latest research shows that its pathogenesis is closely related to the imbalance of gut microbiota. Prunella vulgaris L. is an edible-medicinal plant containing bioactive compounds such as polyphenols that can lower cholesterol and protect the liver. However, whether it has anti MASLD effects has not been reported. The present study aimed to investigate the effect of Prunella vulgaris polyphenols (PVP) on alleviating MASLD from the perspective of the gut-liver axis. PVP composition was characterized via UPLC-MS/MS and HPLC. Enzymatic kinetics, fluorescence quenching, and molecular docking were used to study the inhibition of PVP and rosmarinic acid (RA) on cholesterol esterase (CEase). Effects on liver lipid accumulation and intestinal cholesterol transport were assessed using HepG2 and Caco-2 cell models. A MASLD mouse model was evaluated through ELISA, tissue staining, and 16S rRNA sequencing to determine the efficacy and mechanisms. PVP and RA exhibited anti-competitive inhibition of CEase, with IC50 values of 1.63 ± 0.06 and 0.39 ± 0.17 mg/mL, respectively. RA showed strong binding to CEase. PVP and RA significantly alleviated hepatic lipid accumulation in HepG2 cells, inhibited intestinal cholesterol absorption, and promoted cholesterol efflux in Caco-2 monolayers. In MASLD mice, PVP significantly reduced serum ALT, TBA, and TG, lowered hepatic TC and fecal TBA (P < 0.05), and ameliorated liver pathological damage. In addition, both PVP and RA modified the composition of gut microbiota in the cecum, which characterized by a reduction in bile acid (BA)-related bacteria such as g_UBA7173, g_Bacteroides_H, f_Burkholderiaceae_A, g_Phocaeicola_A, and g_Turicimonas, while increasing f_Lachnospiraceae and f_Oscillospiraceae. PVP ameliorates MASLD by inhibiting CEase and intestinal cholesterol absorption, promoting cholesterol efflux, and regulating TBA levels along with intestinal microbiota homeostasis.

Transcriptomic and immunophenotyping analyses revealed that offspring with cold-exposed dams exhibited suppressed Th17 activity and IL-17 signaling. Cross-fostering and metabolomics identified elevated lithocholic acid (LCA) in maternal milk as a critical mediator of these effects. LCA supplementation recapitulates these benefits through gut microbiota-dependent conversion to 3-oxo-LCA. Furthermore, Clostridium scindens supplementation enhanced 3-oxo-LCA production, suppressed Th17 responses, and alleviated diet-induced hepatic steatosis. Clinically, analysis of the UK Biobank cohort showed that winter conception was associated with a lower risk of metabolic dysfunction-associated steatotic liver disease in offspring. A similar association was observed in the CHARLS cohort in colder northern China. Together, these results identify a maternal cold-microbiota-bile acid-Th17 axis that programs offspring metabolic health and highlight microbial bile acid metabolism as a potential therapeutic target for metabolic diseases."},{"quote":"Moreover, the YJP improved intestinal barrier integrity and upregulated intestinal HIF-1α and occludin expression, reflecting a therapeutic mechanism involving coordinated regulation of the gut-liver axis.","source_id":"42423000","status":"PASS","error":"","abstract_text":"ID: 42423000\nTitle: Exploring the Mechanisms of the Yueju Pill for ALD by Integrating UPLC-QE Orbitrap-MS/MS, Network Pharmacology, and Experimental Verification.\nAbstract: This study integrated UPLC-QE Orbitrap-MS/MS, network pharmacology, and experimental validation to investigate the chemical profile and therapeutic mechanisms of the Yueju pill (YJP) in the treatment of alcoholic liver disease (ALD).

By inhibiting the gastric H⁺/K⁺-ATPase, PPIs suppress acid secretion and impair bacterial killing, thereby promoting gut dysbiosis that disrupts barrier integrity and enhances bacterial translocation, ultimately exacerbating liver injury. PPIs are frequently co-administered with antibiotics for indications such as gastrointestinal bleeding, Spontaneous Bacterial Peritonitis (SBP), other infections, or hepatic encephalopathy prophylaxis, but the consequences of this combined therapy on gut microbial ecology and disease outcomes remain unclear. Our study addresses this gap by showing how PPI use, alone or with antibiotics, reshapes the gut microbiome and aggravates liver disease progression. In previous studies, we showed that PPIs promote dysbiosis and ALD progression in mice and humans by facilitating intestinal expansion and hepatic translocation of Gram-positive Enterococcus. Fecal cytolysin, an Enterococcus faecalis exotoxin that induces hepatocyte death, predicts mortality in patients with alcohol-associated hepatitis (AH). In this study, we have examined the mechanism by which PPIs alone and in combination with non-absorbable antibiotics targeting Gram-positive bacteria influence ALD, as well as the disease mechanisms associated with cytolytic Enterococcus faecalis and the development of therapeutic strategies. In mice, alcohol administration during gastric acid suppression promoted expansion of Gram-positive taxa, including cytolysin-producing Enterococcus. Similarly, PPI use in patients with AH was associated with increased fecal Enterococcus and higher 30-d mortality, underscoring the translational relevance of our findings. Unexpectedly, treatment of acid-suppressed mice with non-absorbable antibiotics designed to suppress Gram-positive bacteria worsened ethanol-induced steatohepatitis: while Enterococcus abundance decreased, Streptococcus and other potentially pathogenic taxa expanded, leading to increased bacterial translocation and aggravated liver injury. In patients with cirrhosis or metabolic dysfunction-associated steatotic liver disease (MASLD), PPIs did not promote Enterococcus expansion, indicating etiology-dependent microbiome responses. Finally, we identified dipalmitoylphosphatidylcholine and Caspase-1 inhibitor as in vitro and in vivo modulators of cytolysin activity, highlighting potential therapeutic avenues. Collectively, our study demonstrates how PPIs and non-absorbable antibiotics targeting Gram-positive bacteria interact with the gut microbiome to drive ALD, underscoring the need for careful therapeutic management."},{"quote":"cis-Gnetin H remodeled the gut microbiota by enriching beneficial genera and reducing pathogenic Staphylococcus.","source_id":"42419122","status":"PASS","error":"","abstract_text":"ID: 42419122\nTitle: Discovery of cis-Gnetin H from peony seed coat as a potent antifibrotic agent modulating hepatic fibro-inflammatory pathways and gut microbiota homeostasis.\nAbstract: Liver fibrosis is a reversible stage of chronic liver disease lacking effective therapies. The peony seed coat, a major byproduct of peony oil production, is rich in bioactive stilbenes. However, its anti-fibrotic potential and underlying mechanisms remain systematically unexplored. This study aimed to isolate stilbenes from peony seed coat, identify the potent anti-fibrotic compounds, and evaluate their anti-fibrotic activity and mechanisms of action. A structure-oriented separation strategy, guided by spectroscopic analysis, enabled the isolation of stilbenes. Anti-fibrotic activity was screened in TGF-β1-induced hepatic stellate cells (HSCs). In vivo efficacy was evaluated in a CCl₄-induced mouse liver fibrosis model. Mechanisms were investigated using transcriptomics, Western blotting, and 16S rRNA gene sequencing. Among seven isolated stilbenes, cis-Gnetin H exhibited the most potent inhibition of HSCs activation by downregulating α-SMA, Collagen I, and Smad3. In CCl₄-treated mice, cis-Gnetin H significantly ameliorated liver injury, inflammation, and fibrosis.

We investigated the effects of 8-hour TRE combined with usual care (UC, a Mediterranean diet-based education program), versus UC alone over 12 weeks on hepatic fat fraction, liver health markers, and fecal microbiota in adults with overweight or obesity. In this multicenter randomized trial, participants (50% women) were assigned to UC (n=49), early TRE (n=49), late TRE (n=52), or self-selected TRE (n=47). Hepatic fat fraction was assessed by MRI; liver markers included elastography-based parameters, liver enzymes, and circulating biomarkers. Fecal microbiota was analyzed by 16S rRNA gene sequencing. Hepatic fat fraction decreased significantly within the three TRE groups (all P≤0.02), but no between-group differences were observed when comparing early TRE (mean difference [MD]: -0.4%; P=0.95), late TRE (MD: -1.5%; P=0.15), and self-selected TRE groups (MD: -0.7%; P=0.77) with the UC group, or among the TRE groups themselves (all P≥0.41). Similarly, no between-group differences were found in liver health markers and fecal microbiota. Participants with metabolic dysfunction-associated steatotic liver disease at baseline as well as those achieving ≥5% weight loss had greater reductions in hepatic fat fraction than those who did not (MD: -2.7 and -2.6%; respectively, both P<0.001). A higher proportion of participants in the TRE groups achieved ≥5% weight loss compared with UC (41-44% vs 16%; P=0.001). These findings suggest that the timing of the eating window in TRE may not impact hepatic fat fraction or microbiota composition beyond the effects of weight loss, though the study was not powered for secondary outcomes. The study was registered on ClinicalTrials.gov (identifier: NCT05310721). NCT05310721 IMPACT AND IMPLICATIONS: Time-restricted eating (TRE) is increasingly used for obesity management, but whether the timing of the eating window influences liver health remains unclear. In this 12-week multicenter randomized trial, adding early, late, or self-selected 8-hour TRE to Mediterranean diet-based usual care led to within-group reductions in MRI-assessed hepatic fat fraction, but did not confer greater improvements in hepatic fat fraction, liver health markers, or fecal microbiota than usual care alone. Participants with baseline metabolic dysfunction-associated steatotic liver disease (MASLD) and those achieving ≥5% weight loss experienced larger reductions in hepatic fat fraction, suggesting these reductions in this context are more closely linked to weight loss and baseline steatosis than to eating-window timing. Clinically, these findings support prioritizing feasible eating schedules and strategies that help patients attain clinically meaningful weight loss, particularly among individuals with MASLD."},{"quote":"Sinensetin administration ameliorated hepatic steatosis, inflammation, and restored intestinal integrity in HFD-fed mice.","source_id":"42421922","status":"PASS","error":"","abstract_text":"ID: 42421922\nTitle: Sinensetin ameliorates established high-fat diet-induced liver injury and intestinal barrier dysfunction through the mitophagy/TLR4/MAPK signaling pathway.\nAbstract: Long-term consumption of a high-fat diet (HFD) causes liver injury characterized by steatosis, inflammation, and fibrosis. Mitophagy, as a selective autophagy, is reported to be involved in the regulation of liver injury.

Sinensetin administration ameliorated hepatic steatosis, inflammation, and restored intestinal integrity in HFD-fed mice. Mechanistically, sinensetin remodeled the gut microbiota, elevating SCFA levels, which activated mitophagy and cleared damaged mitochondria in liver and intestinal tissues, thereby suppressing the toll-like receptor 4 (TLR4)/mitogen-activated protein kinase (MAPK) signaling.

Ceramidases and ceramides are associated with MASH, yet the role of intestinal neutral ceramidase in MASH development remains unclear. Murine models with intestinal epithelial cell (IEC)-specific depletion of neutral ceramidase (Asah2ΔIEC ) or aryl hydrocarbon receptor (AhR ΔIEC) were subjected to either a Western diet (WD) at 6 weeks old for 10-12 months to induce MASH, or a hydrogenated vegetable oil, sucrose, palmitate and cholesterol (HSPC) diet to accelerate MASH progression. Fecal microbiota transplantation was performed in germ-free mice. MASH is associated with the induction of neutral ceramidase, which reshapes the intestinal microbiota and metabolite profiles, leading to increased production of 2-hydroxyhippuric acid (2-HHA). We identified 2-HHA as an inhibitor of AhR signalling, a pathway that normally promotes intestinal fucosylation. Elevated 2-HHA suppresses AhR activity, reduces fucosylation and contributes to MASH and associated airway inflammation in mice fed WD or HSPC diet. Notably, IEC-specific deletion of neutral ceramidase decreases 2-HHA levels, restores AhR signalling, enhances fucosylation and protects against MASH. Consistently, intestinal AhR deficiency exacerbates MASH by reducing intestinal fucosylation, whereas supplementation with fucoidan increases fucosylation, improves barrier function and attenuates MASH. These findings identify intestinal neutral ceramidase as a key driver of MASH through a microbiota-2-HHA-AhR axis that impairs intestinal fucosylation and barrier function, highlighting a potential therapeutic target."},{"quote":"DYMJ treatment restored microbial balance closer to normal-diet (ND) conditions, particularly by elevating nicotinic acid adenine dinucleotide and enriching Bacteroidetes phylum species associated with metabolic health.","source_id":"42395745","status":"PASS","error":"","abstract_text":"ID: 42395745\nTitle: Aqueous extract of Duyun Maojian tea ameliorates the ileal microbiota and associated hepatic metabolome in HFD-induced obese mice.\nAbstract: Duyun Maojian tea (DYMJ), a renowned Chinese green tea, exhibits potential anti-obesity properties, though its mechanisms remain unclear.

Whether inflammatory signals triggered by HFD-induced gut dysbiosis are transmitted to the placenta via the maternal-fetal axis warrant further investigation. This study aims to elucidate the mechanistic connection between maternal gut dysbiosis and placental inflammation, thereby offering insights into microbiota-mediated developmental origins of metabolic diseases in offspring. Female C57BL/6 mice were exposed to high fat diet (HFD) for 5 weeks prior to mating with male mice. Gut microbiota was profiled by using 16 S rRNA sequencing and fecal short-chain fatty acids (SCFAs) were quantified by GC-MS from HFD pregnant mice at gestational day 18.5 (G18.5). Mice were sacrificed at G18.5, and placenta histopathological analysis as well as inflammatory markers and lipopolysaccharide (LPS) level were analyzed. Anti-inflammatory effects of butyrate were evaluated in vitro by using HTR-8/Svneo cells and in vivo through gestational supplementation (0.3 mg/g body weight) in HFD-fed dams. Maternal HFD exposure induced significant placental inflammation as well as hepatic steatosis in the offspring. HFD-fed dams exhibited distinct gut dysbiosis with reduced fecal and serum SCFAs, which was accompanied by elevated placental LPS levels and exacerbated inflammatory responses.

Using a mouse model of acute ethanol gavage, animals received E. faecalis and/or Akk11 under prophylactic or therapeutic regimens. Assessments included liver injury markers, histopathology, lipid profiles, inflammatory cytokines, gut barrier integrity, and gut microbiota composition. E. faecalis exacerbated ethanol-induced hepatic steatosis and injury, showing a paradoxical effect: it increased histological damage while lowering circulating LPS and transaminases. This was linked to upregulated hepatic autophagy (increased Atg7) and reduced cholesterol, yet it promoted neutral lipid accumulation. Importantly, E. faecalis aggravated gut dysbiosis by markedly enriching the pro-inflammatory pathobiont Helicobacter typhlonius and impairing colonic barrier function.

By employing pharmacological, nutritional, or probiotic strategies that attenuate hepatic steatosis, inflammation, and fibrogenesis, researchers have observed a concomitant restoration of gut microbial ecology, intestinal barrier integrity, and metabolic homeostasis, suggesting that the treatment of fatty liver disease is a viable strategy for restoring gut health.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe paradigm of the gut-liver axis suggests that the liver and the gut are functionally interconnected; therefore, interventions targeting one often propagate restorative effects to the other. Evidence demonstrates that the administration of bioactive compounds, probiotics, and targeted therapeutics can mitigate hepatic damage while simultaneously remediating gut dysbiosis. For instance, the modulation of gut-derived metabolites—such as bile acids and short-chain fatty acids—serves as a primary mechanism by which liver-targeted treatments improve intestinal health. Many interventions, such as the use of natural products or pharmacological agents, have been shown to ameliorate hepatic steatosis and inflammatory responses while restoring mucosal integrity, characterized by the upregulation of tight junction proteins. These findings underscore that the liver's metabolic state is intrinsically coupled to the gut microenvironment, and successful management of liver pathology often functions as an indirect, yet effective, therapy for gastrointestinal dysfunction.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   The \"clock-microbiome-metabolite\" axis suggests that chronotherapeutic strategies, such as time-restricted eating, may influence liver health and gut microbial rhythmicity.\n*   Certain antibiotics, while intended to reduce pathogenic bacteria, may paradoxically aggravate liver injury in specific metabolic contexts by inducing microbial shifts.\n*   Gut commensal *Bacteroides fragilis* produces pantothenic acid, which is essential for host intestinal barrier function and metabolic health.\n*   A \"dual-pronged\" mechanism in traditional medicines, such as *Calculus Bovis*, suggests that simultaneous regulation of lipid metabolism and bile acid composition is necessary for holistic gut-liver axis restoration.\n*   The use of engineered bacteria (e.g., *Bacillus subtilis* secreting BAMBI) reveals the potential for the gut-liver axis to serve as a drug delivery pathway for hepatic therapeutics.\n*   Maternal cold exposure programs offspring metabolic health through a bile acid-microbiota-Th17 axis, demonstrating the long-term impact of environmental factors on the gut-liver connection.\n*   Dietary polyphenol extracts, such as those from walnut green husks, improve intestinal morphology and microbial composition in animal models of hepatic fat accumulation.\n*   The gut microbiota-derived extracellular vesicles represent a recently recognized mechanism for cross-kingdom communication regulating hepatic metabolic and immune homeostasis.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

In this study, glucoraphenin (GRE), the major glucosinolate in radish (Raphanus sativus L.) greens and sprouts, was evaluated for its effects on Western diet (WD)-induced metabolic derangements and gut dysfunction in mice. Intaking of 1 mg/kg body weight of GRE with WD for 8 weeks caused significant reductions in adipogenesis indicators such as body weight gains, adipocyte hypertrophy, and serum leptin level. This result was further proved by significant changes in lipogenesis and lipolysis-related protein expressions in adipocyte. Administration of GRE also suppressed development of MASLD, which was observed through reductions in serum ALT and AST and suppressions the expression of FAS, SREBP1, mTOR, SCD1, ACC, and ChREBP in liver tissues. GRE administration effectively prevented the decrease in the gut microbial richness and diversity caused by WD and recovered serum branched-chain amino acids and microbiota-derived purine metabolites (inosine and hypoxanthine). These findings indicate that GRE mitigates WD-induced obesity and MASLD via coordinated regulation of lipid metabolism and the gut-liver axis.\n\nID: 42435783\nTitle: CYP450 Network Shifts in MASLD/MASH: From Pathogenesis to Nutrition-Informed Modulation.\nAbstract: As MASLD/MASH becomes increasingly prevalent in parallel with obesity, metabolic dysfunction, and ultra-processed dietary patterns, understanding how diet-related exposures influence hepatic drug-metabolizing and lipid-metabolizing pathways has become clinically relevant. CYP450 enzymes represent a key interface between metabolic stress, xenobiotic handling, oxidative injury, and nutrition-related exposures, yet their role in MASLD/MASH has not been fully integrated from a nutrition-informed perspective. This review maps nutrition-exposure-CYP relationships across MASLD/MASH by integrating dietary patterns, food-processing exposures, contaminants/additives, and bioactive compounds within a structured qualitative framework. The reviewed evidence suggests that obesity, high-fat diet exposure, fructose co-exposure, and fatty acid composition may reshape hepatic CYP responses through isoform-, exposure-, and endpoint-dependent mechanisms. Human liver tissue and microsome studies provide relatively stronger translational evidence for altered CYP3A4 expression, activity, and clearance in NAFLD/NASH, whereas evidence for many nutrition-related exposures remains primarily animal-based, in vitro, or mechanistic. Macronutrient-related pathways, including fructose with high-fat intake and omega-6/omega-3 oxylipin imbalance, appear to influence CYP-mediated lipid and inflammatory signaling. Food-derived contaminants such as nitrosamines, aflatoxin B1, and acrylamide provide biologically plausible examples of CYP-dependent bioactivation in metabolically vulnerable liver contexts, although direct human MASLD/MASH validation remains limited. Evidence for food additives and phytochemicals is more preliminary and should be interpreted mainly as hypothesis-generating rather than clinically established. Across the reviewed evidence, metabolic inflammation appears to favor pro-oxidant CYP pathways, including CYP2E1 and CYP4A/4F, while suppressing or altering detoxification and epoxygenase-related pathways, including CYP3A and CYP2C/2J. However, changes in CYP expression do not necessarily translate into altered enzymatic activity or clinical clearance. We conclude that nutrition-related CYP remodeling may represent a mechanistic and translational interface linking diet, oxidative injury, xenobiotic handling, and MASLD/MASH progression. Future studies should integrate dietary exposure assessment with CYP activity or clearance phenotypes, oxidative stress biomarkers, gut-liver axis markers, and MASLD/MASH stage-specific clinical outcomes.\n\nID: 42435168\nTitle: Gut-Liver Microbiome and Tumor Microenvironment in Metabolic Dysfunction-Associated Steatotic Liver Disease.\nAbstract: Hepatocellular carcinoma (HCC), the dominant form of primary liver cancer associated with cirrhosis, has been increasing in prevalence in the US and globally. Metabolic dysfunction-associated steatotic liver disease (MASLD), which is linked to the obesity pandemic and growing prevalence of metabolic disorders, has played a major role in this worrisome trend. Notably, up to 50% of MASLD-associated HCC develop in the noncirrhotic liver, suggesting different mechanisms of carcinogenesis as compared to HCC associated with other chronic liver diseases and potentially resulting in delays in diagnosis. Unfortunately, HCC has an unfavorable prognosis once advanced, and systemic therapies used in the management of advanced HCC have limited efficacy and considerable toxicity. More insight into HCC pathophysiology is therefore urgently needed to improve both preventive and therapeutic strategies. The gut-liver axis, and specifically the gut microbiome, appears to play a major role in the development and progression of HCC. MASLD is associated with dysbiosis, and HCC is a serious outcome of a dysfunctional relationship between the liver and the gut microbiome. Microbial-derived metabolites and cell wall components, which reach the liver via the portal and biliary circulation, may have direct oncogenic effects or activate pathways of cell proliferation, inflammation, and immunosuppression, thus altering the liver tumor microenvironment. In addition, the recent discovery of the intratumoral microbiome offers novel opportunities to learn about the host-microbiome relationship, hepatocarcinogenesis, and tumor surveillance. Further insight into the dysfunctional gut-liver axis and immuno-oncology-microbiome axis in MASLD promises to advance strategies for HCC prevention and treatment.\n\nID: 42435155\nTitle: Dietary milk polar lipids ameliorate hepatic lipid accumulation through coordinated regulation of Wnt-PPARγ signaling and remodeling of the gut microbiota.\nAbstract: This study investigated the protective effects of milk polar lipids (MPL) against non-alcoholic fatty liver disease (NAFLD) and explored the underlying mechanisms using a high-fat high-sucrose (HFHS) diet-induced mouse model. MPL diet significantly reduced body weight gain, adiposity, and hepatic lipid accumulation, in addition to decreasing serum levels of liver injury markers. Mechanistically, MPL diet activated hepatic Wnt/β-catenin signaling, as evidenced by increased expression of low-density lipoprotein receptor-related protein 6 (LRP6), Wnt family member 3 A (Wnt3a), and β-catenin. Concurrently, MPL treatment suppressed peroxisome proliferator-activated receptor gamma (PPARγ) and downstream lipogenic proteins involved in triglyceride synthesis and de novo lipogenesis. In addition, MPL diet markedly reshaped the gut microbiota composition disrupted by HFHS feeding. Notably, MPL group showed a significant increased the abundance of Akkermansia muciniphila and short-chain fatty acid-producing bacteria, including members of Romboutsia and Christensenellaceae. These findings demonstrate that dietary MPL effectively attenuates HFHS diet-induced NAFLD through coordinated regulation of hepatic Wnt-PPARγ signaling and gut microbial ecology.\n\nID: 42434935\nTitle: Christensenella massiliensis reduces kynurenine levels and alleviates obesity and related metabolic disorders in model mice.\nAbstract: Next-generation probiotics derived from gut commensals show promise for metabolic disease intervention, yet effective anti-obesity strains remain limited. Here, we demonstrate that oral administration of Christensenella massiliensis markedly alleviates obesity and metabolic dysfunction in high-fat diet-induced obese mice. Treatment reduced food intake, improved glucose tolerance and insulin sensitivity, lowered blood glucose and lipid levels, and attenuated hepatic steatosis and adipose accumulation. C. massiliensis increased the levels of plasma GLP-1 and ileal GLP-1 receptor expression while decreasing ghrelin level, suggesting modulation of gut hormone regulation. C. massiliensis also suppressed systemic and colonic inflammation, accompanied by upregulation of metabolic homeostasis-related genes (ppara, pparg, ucp2). Targeted and quantitative metabolomics identified altered gut metabolic profiles, particularly reduced kynurenine levels. In vitro assays further showed that C. massiliensis converted kynurenine into kynurenic acid, and its lysate reversed kynurenine-induced lipid accumulation, inflammation, and PPARγ suppression in hepatocytes, providing mechanistic support for the observed in vivo metabolic benefits. These findings support C. massiliensis as a promising next-generation probiotic for obesity management.\n\nID: 42429613\nTitle: Gut Microbiota, Immunity, and Metabolism in the Progression From Chronic Liver Disease to Hepatocellular Carcinoma.\nAbstract: The progression from chronic liver injury to hepatocellular carcinoma (HCC) should be viewed as a heterogeneous continuum of immune, metabolic, fibrotic, and microbial remodeling rather than as a single linear route. Although this review uses the MASLD-MASH-fibrosis/cirrhosis-HCC sequence as a mechanistically informative model, the gut-liver-immune framework is also relevant, with important etiology-specific differences, to alcohol-associated liver disease (ALD), chronic hepatitis B virus (HBV) infection, chronic hepatitis C virus (HCV) infection, and mixed-etiology liver disease. Across these contexts, hepatocyte lipotoxicity or viral/alcohol-induced injury, mitochondrial stress, endotoxemia, altered bile-acid signaling, fibrotic remodeling, and immune exhaustion progressively reshape the hepatic microenvironment toward tumor-permissive inflammation and immune escape. We integrate transcriptomic, single-cell, spatial, microbial, and metabolomic evidence to define stage- and etiology-dependent immunometabolic states. Particular emphasis is placed on microbial metabolites, including short-chain fatty acids, secondary bile acids, and tryptophan-derived indoles, which engage host receptors such as FFAR2/3, GPR109A, FXR, TGR5, AhR, and PXR to influence lipid metabolism, epithelial barrier integrity, cytokine programs, epigenetic remodeling, and antitumor surveillance. We further discuss how sex, baseline microbiome composition, hepatic zonation, and preclinical model selection influence disease trajectories and therapeutic responses. By focusing on the gut microbiota-metabolism-immunity axis, this review provides a systems-level framework for biomarker discovery, risk stratification, precision nutrition, and rational combination therapies. Targeting the coordinated interplay among diet, microbiota, metabolism, immunity, and the hepatic spatial niche may help intercept chronic liver disease before malignant transformation and improve therapeutic responses in established HCC.\n\nID: 42428317\nTitle: Herbal medicines modulate gut microbiota in metabolic diseases: a review.\nAbstract: Metabolic diseases-including obesity, type 2 diabetes mellitus (T2DM), and non-alcoholic fatty liver disease (NAFLD)-affect over 1 billion individuals globally and are characterized by insulin resistance, chronic inflammation, and gut microbiota dysbiosis. Herbal medicines offer multi-component therapeutic potential through microbiota modulation, but mechanistic insights remain fragmented. This review synthesizes recent advances in herbal medicine-mediated gut microbiota regulation in metabolic diseases and delineates underlying molecular mechanisms. A comprehensive literature search was conducted across PubMed and Web of Science. Search strategies employed MeSH terms and free-text keywords encompassing herbal medicines, gut microbiota, and metabolic diseases. Two authors performed study selection and data extraction. Evidence synthesis was structured according to intervention type and metabolic disease category. Herbal polysaccharides and other compounds consistently increased beneficial bacteria and promoted short-chain fatty acids (SCFAs) production, improving intestinal barrier integrity via ZO-1/Occludin upregulation and attenuating TLR4/NF-κB-mediated inflammation. Herbal formulations exerted synergistic effects by remodeling microbial community structure, correcting SCFA/bile acid imbalances, and activating IRS1/PI3K/AKT insulin signaling. Notably, Lactobacillus and Akkermansia emerged as recurrent beneficial targets across multiple herbal interventions. However, evidence is predominantly preclinical, and translational validity to humans requires further validation. Herbal medicines ameliorate metabolic diseases through multi-target gut microbiota modulation, involving SCFA production, bile acid metabolism, and inflammatory pathway attenuation. These mechanistic insights support the development of microbiota-targeted herbal therapeutics, though clinical translation necessitates standardized formulations and rigorous human trials.\n\nID: 42428305\nTitle: Prunella vulgaris polyphenols mediate the gut-liver axis to improve MASLD: regulating cholesterol metabolism and gut microbiota.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most prevalent chronic liver disease worldwide. The latest research shows that its pathogenesis is closely related to the imbalance of gut microbiota. Prunella vulgaris L. is an edible-medicinal plant containing bioactive compounds such as polyphenols that can lower cholesterol and protect the liver. However, whether it has anti MASLD effects has not been reported. The present study aimed to investigate the effect of Prunella vulgaris polyphenols (PVP) on alleviating MASLD from the perspective of the gut-liver axis. PVP composition was characterized via UPLC-MS/MS and HPLC. Enzymatic kinetics, fluorescence quenching, and molecular docking were used to study the inhibition of PVP and rosmarinic acid (RA) on cholesterol esterase (CEase). Effects on liver lipid accumulation and intestinal cholesterol transport were assessed using HepG2 and Caco-2 cell models. A MASLD mouse model was evaluated through ELISA, tissue staining, and 16S rRNA sequencing to determine the efficacy and mechanisms. PVP and RA exhibited anti-competitive inhibition of CEase, with IC50 values of 1.63 ± 0.06 and 0.39 ± 0.17 mg/mL, respectively. RA showed strong binding to CEase. PVP and RA significantly alleviated hepatic lipid accumulation in HepG2 cells, inhibited intestinal cholesterol absorption, and promoted cholesterol efflux in Caco-2 monolayers. In MASLD mice, PVP significantly reduced serum ALT, TBA, and TG, lowered hepatic TC and fecal TBA (P < 0.05), and ameliorated liver pathological damage. In addition, both PVP and RA modified the composition of gut microbiota in the cecum, which characterized by a reduction in bile acid (BA)-related bacteria such as g_UBA7173, g_Bacteroides_H, f_Burkholderiaceae_A, g_Phocaeicola_A, and g_Turicimonas, while increasing f_Lachnospiraceae and f_Oscillospiraceae. PVP ameliorates MASLD by inhibiting CEase and intestinal cholesterol absorption, promoting cholesterol efflux, and regulating TBA levels along with intestinal microbiota homeostasis. Our findings suggest that PVP and RA deserve further investigation as potential modulators of cholesterol metabolism in MASLD.\n\nID: 42425970\nTitle: Maternal cold exposure improves offspring metabolic health via a milk lithocholic acid-microbiota-Th17 axis.\nAbstract: Metabolic diseases are rising with a trend toward earlier onset, yet effective preventive strategies remain limited. While cold exposure improves metabolic health in adults, its role during pregnancy in shaping offspring metabolic outcomes remains unknown. Herein, we demonstrate that maternal cold exposure in early pregnancy markedly improved offspring glucose tolerance, insulin sensitivity, and hepatic lipid metabolism when challenged with a Western diet, and the benefits persisted into late adulthood. Transcriptomic and immunophenotyping analyses revealed that offspring with cold-exposed dams exhibited suppressed Th17 activity and IL-17 signaling. Cross-fostering and metabolomics identified elevated lithocholic acid (LCA) in maternal milk as a critical mediator of these effects. LCA supplementation recapitulates these benefits through gut microbiota-dependent conversion to 3-oxo-LCA. Furthermore, Clostridium scindens supplementation enhanced 3-oxo-LCA production, suppressed Th17 responses, and alleviated diet-induced hepatic steatosis. Clinically, analysis of the UK Biobank cohort showed that winter conception was associated with a lower risk of metabolic dysfunction-associated steatotic liver disease in offspring. A similar association was observed in the CHARLS cohort in colder northern China. Together, these results identify a maternal cold-microbiota-bile acid-Th17 axis that programs offspring metabolic health and highlight microbial bile acid metabolism as a potential therapeutic target for metabolic diseases.\n\nID: 42423000\nTitle: Exploring the Mechanisms of the Yueju Pill for ALD by Integrating UPLC-QE Orbitrap-MS/MS, Network Pharmacology, and Experimental Verification.\nAbstract: This study integrated UPLC-QE Orbitrap-MS/MS, network pharmacology, and experimental validation to investigate the chemical profile and therapeutic mechanisms of the Yueju pill (YJP) in the treatment of alcoholic liver disease (ALD). Chemical analysis identified 91 compounds in the YJP. After SwissADME screening, 45 active ingredients were predicted as potential bioactive compounds. By overlapping the targets of these compounds with ALD-related targets, a \"component-target-disease\" network was constructed, revealing 183 common targets. Enrichment analysis indicated that YJP exerts its therapeutic effects through multiple pathways, including the HIF-1 signaling pathway. In animal experiments, an ALD mouse model was established using the Lieber-DeCarli ethanol liquid diet. YJP intervention significantly reduced serum TG, AST, and ALT levels, alleviated hepatic lipid deposition and collagen deposition, improved liver mitochondrial homeostasis, and decreased hepatic HIF-1α expression. Moreover, the YJP improved intestinal barrier integrity and upregulated intestinal HIF-1α and occludin expression, reflecting a therapeutic mechanism involving coordinated regulation of the gut-liver axis.\n\nID: 42421214\nTitle: Non-absorbable antibiotics worsen alcohol-associated liver disease in gastric acid-suppressed mice.\nAbstract: Gastric acid-suppressive medications, particularly proton pump inhibitors (PPIs), are commonly used in patients with alcohol-associated liver disease (ALD) to prevent and manage upper gastrointestinal bleeding, gastroesophageal reflux disease, and non-steroidal anti-inflammatory/aspirin-induced gastroesophageal damage. By inhibiting the gastric H⁺/K⁺-ATPase, PPIs suppress acid secretion and impair bacterial killing, thereby promoting gut dysbiosis that disrupts barrier integrity and enhances bacterial translocation, ultimately exacerbating liver injury. PPIs are frequently co-administered with antibiotics for indications such as gastrointestinal bleeding, Spontaneous Bacterial Peritonitis (SBP), other infections, or hepatic encephalopathy prophylaxis, but the consequences of this combined therapy on gut microbial ecology and disease outcomes remain unclear. Our study addresses this gap by showing how PPI use, alone or with antibiotics, reshapes the gut microbiome and aggravates liver disease progression. In previous studies, we showed that PPIs promote dysbiosis and ALD progression in mice and humans by facilitating intestinal expansion and hepatic translocation of Gram-positive Enterococcus. Fecal cytolysin, an Enterococcus faecalis exotoxin that induces hepatocyte death, predicts mortality in patients with alcohol-associated hepatitis (AH). In this study, we have examined the mechanism by which PPIs alone and in combination with non-absorbable antibiotics targeting Gram-positive bacteria influence ALD, as well as the disease mechanisms associated with cytolytic Enterococcus faecalis and the development of therapeutic strategies. In mice, alcohol administration during gastric acid suppression promoted expansion of Gram-positive taxa, including cytolysin-producing Enterococcus. Similarly, PPI use in patients with AH was associated with increased fecal Enterococcus and higher 30-d mortality, underscoring the translational relevance of our findings. Unexpectedly, treatment of acid-suppressed mice with non-absorbable antibiotics designed to suppress Gram-positive bacteria worsened ethanol-induced steatohepatitis: while Enterococcus abundance decreased, Streptococcus and other potentially pathogenic taxa expanded, leading to increased bacterial translocation and aggravated liver injury. In patients with cirrhosis or metabolic dysfunction-associated steatotic liver disease (MASLD), PPIs did not promote Enterococcus expansion, indicating etiology-dependent microbiome responses. Finally, we identified dipalmitoylphosphatidylcholine and Caspase-1 inhibitor as in vitro and in vivo modulators of cytolysin activity, highlighting potential therapeutic avenues. Collectively, our study demonstrates how PPIs and non-absorbable antibiotics targeting Gram-positive bacteria interact with the gut microbiome to drive ALD, underscoring the need for careful therapeutic management.\n\nID: 42421035\nTitle: The impact of synbiotic yogurt consumption on insulin-resistance surrogates, atherogenic and novel anthropometric indices in adults with metabolic syndrome: a randomized clinical trial.\nAbstract: Metabolic syndrome (MetS) represents a well-recognized contributor to cardiovascular risk, and synbiotics have recently gained attention as a potential dietary strategy for its management. The present study aimed to determine whether a novel synbiotic yogurt formulated with Lactobacillus plantarum, Lactobacillus pentosus, and the yeast Kluyveromyces marxianus affects atherogenic markers, cardiometabolic parameters, and insulin resistance surrogates in individuals among individuals diagnosed with MetS. A 12-week double-blind, standard-yogurt-controlled randomized clinical trial was conducted, enrolling 44 adults with MetS who were randomized to either 300 g/day of synbiotic yogurt (n = 22) or a matched control yogurt (n = 22); 41 (22 synbiotic, 19 control yogurt) completed and were analyzed. A comprehensive panel of cardiometabolic outcomes was evaluated at baseline and week 12, encompassing atherogenic indices including the Atherogenic Index of Plasma (AIP), Castelli's Risk Index-I (CRI-I), Castelli's Risk Index-II (CRI-II), Atherogenic Coefficient (AC), and oxidized low-density lipoprotein (ox-LDL); cardiometabolic measures including the Visceral Adiposity Index (VAI), Waist Triglyceride Index (WTI), and Cardiometabolic Index (CMI); body shape and adiposity indices including A Body Shape Index (ABSI), Body Roundness Index (BRI), Body Adiposity Index (BAI), Conicity Index, Abdominal Volume Index (AVI), and Weight-adjusted Waist Index (WWI); and surrogate markers of insulin resistance including the Triglyceride-Glucose Index (TyG), Hepatic Steatosis Index (HSI), triglyceride to high-density lipoprotein ratio (TG/HDL), TyG-Body Mass Index (TyG-BMI), TyG-Waist Circumference (TyG-WC), Metabolic Score for Insulin Resistance (METS-IR), and Lipid Accumulation Product (LAP). At the end of the 12-week period, statistically significant between-group differences were limited to four indices, namely CRI-I (p = 0.039), CRI-II (p = 0.038), AC (p = 0.039), and BAI (p = 0.027), all of which favored the control group. Within-group analyses indicated that the control arm experienced significant reductions in AIP, CRI-I, CRI-II, AC, TG/HDL, and METS-IR, whereas participants in the synbiotic arm demonstrated significant decreases only in TyG and TyG-BMI. No significant changes were observed in other indices. According to our findings, 12 weeks of daily synbiotic yogurt consumption did not significantly improve insulin resistance surrogates, atherogenic, and novel anthropometric indices in adults with MetS.

The peony seed coat, a major byproduct of peony oil production, is rich in bioactive stilbenes. However, its anti-fibrotic potential and underlying mechanisms remain systematically unexplored. This study aimed to isolate stilbenes from peony seed coat, identify the potent anti-fibrotic compounds, and evaluate their anti-fibrotic activity and mechanisms of action. A structure-oriented separation strategy, guided by spectroscopic analysis, enabled the isolation of stilbenes. Anti-fibrotic activity was screened in TGF-β1-induced hepatic stellate cells (HSCs). In vivo efficacy was evaluated in a CCl₄-induced mouse liver fibrosis model. Mechanisms were investigated using transcriptomics, Western blotting, and 16S rRNA gene sequencing. Among seven isolated stilbenes, cis-Gnetin H exhibited the most potent inhibition of HSCs activation by downregulating α-SMA, Collagen I, and Smad3. In CCl₄-treated mice, cis-Gnetin H significantly ameliorated liver injury, inflammation, and fibrosis. Mechanistically, cis-Gnetin H activated the Nrf2/HO-1 antioxidant pathway while suppressing NF-κB and TGF-β1/Smad signaling. Furthermore, cis-Gnetin H remodeled the gut microbiota by enriching beneficial genera and reducing pathogenic Staphylococcus. This microbial modulation was accompanied by increased production of SCFAs, which correlated strongly with improved hepatic parameters. cis-Gnetin H acts as an anti-fibrotic agent through modulating hepatic inflammatory and fibrotic signaling, and regulating the gut-liver axis via microbiota restoration and metabolite enhancement. These findings highlight cis-Gnetin H as a promising therapeutic candidate and support the high-value utilization of peony agricultural byproducts.\n\nID: 42413768\nTitle: Time-restricted eating, liver health, and fecal microbiota in adults with overweight or obesity: a randomized controlled trial.\nAbstract: The optimal eating window for time-restricted eating (TRE) remains unclear. We investigated the effects of 8-hour TRE combined with usual care (UC, a Mediterranean diet-based education program), versus UC alone over 12 weeks on hepatic fat fraction, liver health markers, and fecal microbiota in adults with overweight or obesity. In this multicenter randomized trial, participants (50% women) were assigned to UC (n=49), early TRE (n=49), late TRE (n=52), or self-selected TRE (n=47). Hepatic fat fraction was assessed by MRI; liver markers included elastography-based parameters, liver enzymes, and circulating biomarkers. Fecal microbiota was analyzed by 16S rRNA gene sequencing. Hepatic fat fraction decreased significantly within the three TRE groups (all P≤0.02), but no between-group differences were observed when comparing early TRE (mean difference [MD]: -0.4%; P=0.95), late TRE (MD: -1.5%; P=0.15), and self-selected TRE groups (MD: -0.7%; P=0.77) with the UC group, or among the TRE groups themselves (all P≥0.41). Similarly, no between-group differences were found in liver health markers and fecal microbiota. Participants with metabolic dysfunction-associated steatotic liver disease at baseline as well as those achieving ≥5% weight loss had greater reductions in hepatic fat fraction than those who did not (MD: -2.7 and -2.6%; respectively, both P<0.001). A higher proportion of participants in the TRE groups achieved ≥5% weight loss compared with UC (41-44% vs 16%; P=0.001). These findings suggest that the timing of the eating window in TRE may not impact hepatic fat fraction or microbiota composition beyond the effects of weight loss, though the study was not powered for secondary outcomes. The study was registered on ClinicalTrials.gov (identifier: NCT05310721). NCT05310721 IMPACT AND IMPLICATIONS: Time-restricted eating (TRE) is increasingly used for obesity management, but whether the timing of the eating window influences liver health remains unclear. In this 12-week multicenter randomized trial, adding early, late, or self-selected 8-hour TRE to Mediterranean diet-based usual care led to within-group reductions in MRI-assessed hepatic fat fraction, but did not confer greater improvements in hepatic fat fraction, liver health markers, or fecal microbiota than usual care alone. Participants with baseline metabolic dysfunction-associated steatotic liver disease (MASLD) and those achieving ≥5% weight loss experienced larger reductions in hepatic fat fraction, suggesting these reductions in this context are more closely linked to weight loss and baseline steatosis than to eating-window timing. Clinically, these findings support prioritizing feasible eating schedules and strategies that help patients attain clinically meaningful weight loss, particularly among individuals with MASLD.\n\nID: 42412329\nTitle: Mitophagy in Metabolic Dysfunction-Associated Fatty Liver Disease: Mechanisms, Regulatory Networks, and Therapeutic Perspectives.\nAbstract: Metabolic dysfunction-associated fatty liver disease (MASLD) represents the most prevalent chronic liver disorder globally, with pathogenesis closely linked to insulin resistance, obesity, and gut microbiota dysbiosis. Mitochondrial dysfunction is central to MASLD progression, and mitophagy-a selective form of autophagy that clears damaged mitochondria-plays a crucial role in maintaining cellular homeostasis. This review systematically delineates the molecular mechanisms, regulatory networks, and therapeutic implications of mitophagy in MASLD. We first outline the core machinery of mitophagy, encompassing both ubiquitin-dependent and ubiquitin-independent pathways. We then discuss how impaired mitophagy drives the disease progression of MASLD from the perspective of different hepatic cell types. Furthermore, we summarize the multilayered upstream regulatory network governing mitophagy in the context of MASLD, involving key signaling pathways, metabolic reprogramming, inflammatory cues, epigenetic modifications, and intercellular crosstalk. Finally, we examine therapeutic strategies targeting mitophagy-including clinical and preclinical agents, natural compounds, physical interventions, and emerging technologies-and highlight the challenges posed by its dualistic nature. Moving forward, integrating spatiotemporal dynamics with precision targeting will be essential to translate mitophagy modulation from mechanistic insight into viable clinical therapies for MASLD.\n\nID: 42409325\nTitle: Dysregulation of the bile acid signaling network in non-alcoholic fatty liver disease: Mechanisms and a new paradigm of precision network pharmacology.\nAbstract: Non-alcoholic fatty liver disease (NAFLD) has emerged as the most prevalent chronic liver disease worldwide, characterized by complex pathogenesis and a lack of effective therapies. The bile acid (BA) \"synthesis-transport-signaling\" axis serves as a central hub integrating gut microbiota, host metabolism, and immunity, and its network dysregulation is a key driver of NAFLD progression. This review systematically elaborates how dysfunction of key enzymes, transporters, and receptors (e.g., farnesoid X receptor (FXR), Takeda G protein-coupled receptor 5 (TGR5)) within this axis drives hepatic steatosis, inflammation, and fibrosis by reshaping the BA pool, disrupting enterohepatic circulation, and perturbing receptor cross-talk. Current pharmacological strategies targeting single nodes are constrained by interspecies differences in BA profiles, network complexity, and off-target effects, posing significant challenges to their efficacy and safety. Consequently, we propose a paradigm shift from \"single-target\" approaches towards \"precision network pharmacology.\" This entails developing novel bile acid conjugates, dual-target or multi-target agents, designing rational combination therapies, and stratifying patients based on their BA metabolic phenotypes. Guided by human-relevant models and novel biomarkers, this framework aims to systemically restore BA signaling network homeostasis and enable personalized intervention, offering a novel theoretical and translational roadmap for conquering NAFLD.\n\nID: 42406061\nTitle: Bile Acid Pool Expansion and Hemodynamic Associations of the Secondary-to-Primary Bile Acid Ratio in Adult Fontan Circulation.\nAbstract: We previously reported that adults with Fontan circulation have elevated plasma bile acids, including multiple individual bile acid species, associated with frailty, impaired exercise capacity, and adverse resting and post-exercise hemodynamics. Whether the secondary-to-primary bile acid ratio provides additional insight into gut-liver-circulatory interactions in this population is unknown. We performed a secondary analysis of a previously published prospective cohort of 20 adults with Fontan circulation and 20 matched healthy controls. Primary bile acids were defined as cholic acid, chenodeoxycholic acid, and their direct conjugated, sulfated, glucuronidated, and dehydrocholic derivatives. Secondary bile acids included deoxycholic, lithocholic, ursodeoxycholic, hyodeoxycholic, and related downstream derivatives. The secondary-to-primary ratio was calculated as summed secondary-derived bile acids divided by summed primary-derived bile acids. Group comparisons used Mann-Whitney U testing. Within Fontan patients, associations with body composition, exercise performance, and resting/post-exercise hemodynamics were assessed using Spearman correlation with Benjamini-Hochberg correction. The secondary-to-primary ratio was numerically lower in Fontan patients than controls: 0.80 [0.39-1.22] vs. 1.32 [0.70-1.83]; P = 0.10. However, both primary-derived bile acids: 6333 [3473-10899] vs. 2102 [1166-3662] nM; P = 0.004, and secondary-derived bile acids: 4431 [2529-7095] vs. 2468 [1786-3660] nM; P = 0.008, were significantly increased. Within Fontan patients, higher ratio correlated with lower cardiac index/cardiac power index, and higher total peripheral resistance index. In adult Fontan circulation, bile acid pool expansion, particularly primary species, is the dominant abnormality. The secondary-to-primary ratio provides complementary compositional information and appears linked to hemodynamic burden. The ratio did not distinguish groups and should be interpreted with absolute pool size.\n\nID: 42403915\nTitle: Intestinal neutral ceramidase exacerbates MASH pathogenesis.\nAbstract: Metabolic dysfunction-associated steatotic liver disease and its more severe manifestation, metabolic dysfunction-associated steatohepatitis (MASH), are intimately linked to genetic factors, gut microbiota and barrier alteration. Ceramidases and ceramides are associated with MASH, yet the role of intestinal neutral ceramidase in MASH development remains unclear. Murine models with intestinal epithelial cell (IEC)-specific depletion of neutral ceramidase (Asah2ΔIEC ) or aryl hydrocarbon receptor (AhR ΔIEC) were subjected to either a Western diet (WD) at 6 weeks old for 10-12 months to induce MASH, or a hydrogenated vegetable oil, sucrose, palmitate and cholesterol (HSPC) diet to accelerate MASH progression. Fecal microbiota transplantation was performed in germ-free mice. MASH is associated with the induction of neutral ceramidase, which reshapes the intestinal microbiota and metabolite profiles, leading to increased production of 2-hydroxyhippuric acid (2-HHA). We identified 2-HHA as an inhibitor of AhR signalling, a pathway that normally promotes intestinal fucosylation. Elevated 2-HHA suppresses AhR activity, reduces fucosylation and contributes to MASH and associated airway inflammation in mice fed WD or HSPC diet. Notably, IEC-specific deletion of neutral ceramidase decreases 2-HHA levels, restores AhR signalling, enhances fucosylation and protects against MASH. Consistently, intestinal AhR deficiency exacerbates MASH by reducing intestinal fucosylation, whereas supplementation with fucoidan increases fucosylation, improves barrier function and attenuates MASH. These findings identify intestinal neutral ceramidase as a key driver of MASH through a microbiota-2-HHA-AhR axis that impairs intestinal fucosylation and barrier function, highlighting a potential therapeutic target.\n\nID: 42402302\nTitle: Polysaccharide-gut microbiota interactions in metabolic diseases: Structural selectivity, mediating mechanisms, and evidence deficiencies: A review.\nAbstract: Polysaccharides from food and medicinal sources are promising candidates for nutritional interventions in chronic metabolic diseases. Because intact polysaccharides are generally poorly absorbed after oral administration, their systemic effects cannot be fully explained by conventional models of absorption and direct action on target organs. Increasing attention has therefore focused on their gastrointestinal fate and on how microbial utilization and gut-derived metabolites may influence host metabolism. This review examines how molecular weight, monosaccharide composition, glycosidic linkage type, branching, charge, and conformation affect resistance to upper gastrointestinal digestion, microbial recognition, and fermentation. It further evaluates the roles of short-chain fatty acids, bile acids, tryptophan-derived metabolites, and barrier-associated inflammatory signals in glucose homeostasis, lipid metabolism, and immune regulation. The strength of evidence varies substantially across these pathways. Short-chain fatty acid-related mechanisms and the gut-liver axis have relatively consistent preclinical support, whereas bile acid signaling and intestinal barrier pathways are supported by moderate mechanistic evidence. Tryptophan metabolite-mediated regulation and the gut-brain axis remain largely associative or preclinical, with limited validation in controlled human studies. These gut-derived processes may contribute to the regulation of metabolic dysfunction-associated steatotic liver disease (MASLD), obesity, insulin resistance, and cardiometabolic disorders. Future studies should establish causal links among defined glycan structures, selective microbial utilization, gut-derived mediators, and clinically relevant outcomes, while advancing standardized characterization, biomarker-guided evaluation, and carefully validated precision nutrition strategies.\n\nID: 42399985\nTitle: Gut microbiota-derived extracellular vesicles: bridging microbial-host crosstalk in metabolic disorders.\nAbstract: Gut microbiota-derived extracellular vesicles have emerged as crucial mediators in microbe-host communication, not only facilitating intracellular communication, quorum sensing, and horizontal gene transfer among bacteria but also playing a central role in cross-kingdom dialogue. In recent years, bacterial extracellular vesicles (BEVs) have attracted widespread attention due to their ability to carry a diverse array of bioactive molecules-such as proteins, lipids, and nucleic acids-and deliver them to host cells, thereby precisely regulating host metabolic and immune homeostasis. This review systematically elaborates the entire biological process of BEVs, from their biogenesis to functional interactions with host cells, with a specific emphasis on revealing their roles in the pathogenesis of various metabolic diseases-including obesity, type 2 diabetes (T2DM), metabolic dysfunction-associated steatotic liver disease (MASLD), atherosclerosis, and hypertension-at both molecular and cellular levels. Furthermore, leveraging their inherent stability, biocompatibility, and targeting capabilities, we discuss the translational potential and challenges of BEVs in the diagnosis and treatment of metabolic disorders. Beyond summarizing the latest research advances on BEVs in metabolic disorders, this review provides a critical analysis of current mechanistic insights and clinical translation pathways, aiming to establish a theoretical framework for developing novel microbiome-based metabolic interventions. Deciphering the BEV-mediated microbiota-host interaction network holds promise for pioneering new strategies for the precision prevention and treatment of metabolic disease.\n\nID: 42398618\nTitle: Dihydroberberine in metabolic disorders: Bioavailability, molecular mechanisms, toxicology, and future perspectives.\nAbstract: The global prevalence of metabolic diseases, including obesity, type 2 diabetes mellitus (T2DM), and metabolic dysfunction-associated steatotic liver disease (MASLD), continues to rise, representing a major global health threat and economic burden. Dihydroberberine (DHB), a reduced derivative of berberine (BBR), has recently garnered attention due to its superior lipophilicity and intestinal absorption. Pharmacokinetic studies suggested that DHB achieves significantly higher blood concentrations compared to BBR at equivalent doses. This review systematically synthesized the current preclinical evidence regarding the metabolic regulatory mechanisms of DHB. Key pharmacological targets identified in cell and animal models included the activation of AMP-activated protein kinase (AMPK) and glucokinase (GCK), modulation of lipid metabolism, and attenuation of inflammatory and oxidative stress pathways. Furthermore, DHB interacted extensively with the gut microbiota, acting both as a microbial metabolite of BBR and a modulator of microbial composition. Toxicological assessments indicated a favorable safety profile, although potential risks such as hERG channel inhibition required careful evaluation. Importantly, while in vitro and animal studies demonstrated significant metabolic benefits, human clinical trials assessing direct disease outcomes remained highly limited. This review highlighted the pharmacokinetic advantages of DHB and outlined the critical translational gaps that must be addressed in future research.\n\nID: 42395037\nTitle: Metabolic dysfunction-associated steatotic liver disease and metabolic dysfunction-associated alcohol-related liver disease in human immunodeficiency virus.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) and metabolic dysfunction-associated alcohol-related liver disease (MetALD) have emerged as increasingly important sources of morbidity among people living with human immunodeficiency virus (HIV). Advances in antiretroviral therapy have substantially improved life expectancy in people living with HIV (PLWH), but have also unmasked a growing burden of metabolic comorbidities which contribute to steatotic liver disease. Recent shifts in nomenclature and the introduction of MetALD emphasize metabolic dysfunction and graded alcohol exposure as central drivers of disease and are particularly relevant to PLWH, a population in whom overlapping metabolic and behavioral risk factors are common. Epidemiologic studies demonstrate that MASLD affects approximately one-third to one-half of PLWH worldwide, often occurring at younger ages and lower body mass index thresholds than in HIV-negative individuals. Emerging data further highlight the synergistic contribution of metabolic dysfunction and alcohol use to accelerated fibrosis progression in PLWH. Pathophysiologic mechanisms linking HIV infection to MASLD and MetALD include chronic immune activation and systemic inflammation, antiretroviral therapy-associated metabolic effects, altered adipose tissue distribution, gut-liver axis dysregulation, and alcohol-metabolic synergy. This review synthesizes contemporary evidence on the definitions, epidemiology, pathogenesis, clinical assessment, and management of MASLD and MetALD in PLWH.\n\nID: 42395006\nTitle: Microbiome-mediated pharmacology of ginseng: Mechanistic insights into metabolic regulation and therapeutic potential.\nAbstract: Ginseng, a traditional medicinal herb with a favorable safety profile, has long been used to promote systemic health. Recent studies reveal that many of its beneficial effects are mediated through interactions with the gut microbiota. Microbial enzymes convert parent ginsenosides into more absorbable and bioactive metabolites such as compound K, while ginseng reciprocally remodels the microbial community and metabolite composition by promoting the growth of beneficial taxa including Akkermansia, Bifidobacterium, and Lactobacillus. These bidirectional interactions modulate host metabolic, immune, and intestinal barrier functions. The ginseng-microbiome interplay regulates microbial and host-derived metabolites such as short-chain fatty acids, bile acids, and indole derivatives, which in turn activate key signaling pathways including FXR/TGR5, FFAR, AMPK, and Nrf2. Through these mechanisms, ginseng improves lipid metabolism, enhances insulin sensitivity, alleviates low-grade inflammation, and ameliorates metabolic abnormalities such as obesity, insulin resistance, and nonalcoholic fatty liver disease (NAFLD). This review provides a comprehensive synthesis of the ginseng-microbiota metabolic axis, focusing on its mechanistic basis in metabolic regulation and related disorders. We also highlight the therapeutic convergence between ginseng and probiotics possessing ginsenoside-hydrolyzing enzymes, discuss strategies for strain selection and co-administration, and outline future directions in precision, microbiome-informed formulations and clinical trial design. Collectively, current evidence supports the ginseng-microbiota interactions as a promising therapeutic platform for restoring metabolic homeostasis and managing metabolic diseases.\n\nID: 42394773\nTitle: Letter to the Editor: Circadian and microbial misalignment in metabolic dysfunction-associated steatotic liver disease - mechanistic insights and chronotherapeutic potential.\nAbstract: We read with interest the article by Rusman et al published in World Journal of Experimental Medicine. Beyond microbial composition, the gut-liver axis is a rhythmic system regulated by a bidirectional interaction between host clocks and the gut microbiota. Social jetlag induces \"temporal dysbiosis\", disrupting the timing of metabolites and compromising the intestinal barrier, which exacerbates metabolic injury in metabolic dysfunction-associated steatotic liver disease. Restoration of these rhythms through chronotherapeutic approaches provides an effective method to restore alignment and improve clinical outcomes. Specifically, social jetlag desynchronizes hepatic clocks and disrupts microbially-modified bile acid signaling, promoting fat accumulation. Chronotherapeutic strategies like time-restricted eating can effectively mitigate disease progression by \"reprogramming\" the liver transcriptome and reducing hepatic triglycerides.\n\nID: 42392795\nTitle: [Research progress on intervention of active components of Bupleuri Radix in metabolic dysfunction-associated fatty liver disease based on multiple parallel strike theory].\nAbstract: Metabolic dysfunction-associated fatty liver disease(MAFLD) is a prevalent chronic liver disease worldwide. Due to its complex pathogenesis, there is currently no specific drug capable of intervening throughout the entire pathological process, nor a unified and definitive treatment protocol in clinical practice. In traditional Chinese medicine, MAFLD falls under the category of diseases such as "hypochondriac pain" and "liver disease", with the core pathogenesis being "stagnation of the liver meridian and obstruction of Qi movement". The pharmacological characteristics of Bupleuri Radix(BR), which "soothes the liver, relieves stagnation, and promotes Qi movement", are highly consistent with this pathogenesis. Furthermore, data mining studies have shown that BR is among the most frequently used herbs in TCM clinical protocols for treating MAFLD, and its herb pairs and classic formulas have demonstrated favorable therapeutic effects in clinical application. Modern pharmacological studies have also confirmed that BR is rich in active ingredients, including saponins(e.g., saikosaponin A/D/B2), volatile oils(e.g., D-limonene, hexanoic acid), flavonoids(e.g., quercetin, rutin, kaempferol), and polysaccharides. These active ingredients can target multiple pathological aspects of the "multiple parallel hits" in MAFLD, such as improving insulin resistance(IR), alleviating endoplasmic reticulum stress(ERS), repairing mitochondrial function, regulating oxidative stress(OS) response, modulating intestinal microbiota imbalance, and inhibiting inflammasome activation, thereby slowing the progress of MAFLD. Its mechanism of action is closely related to the regulation of PI3K/Akt, PPAR, Nrf2, AMPK, MAPK, PINK1/Parkin, NLRP3 inflammasome and the "gut-liver axis", reflecting the integrative regulatory advantages of TCM's multi-component, multi-target and multi-mechanism approach. Future in-depth studies should focus on precise component profiling of BR, validation of key targets, and the synergistic mechanisms within "formula-component" interactions to better leverage the value of BR in the prevention and treatment of MAFLD.\n\nID: 42392672\nTitle: Interplay between MASLD, obesity and type 2 diabetes: epidemiology, shared pathways and clinical implications.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD), obesity and type 2 diabetes mellitus (T2DM) are interconnected global epidemics that frequently coexist and mutually reinforce disease progression and adverse clinical outcomes. MASLD, the most prevalent chronic liver disease worldwide, is now recognised as a hepatic manifestation of systemic metabolic dysfunction. The coexistence of the triad markedly accelerates MASLD progression, heightens cardiometabolic risk and shifts mortality patterns towards cardiovascular disease, the leading cause of death in affected populations. However, most available data describe MASLD in association with either obesity or T2DM individually, while robust epidemiological or mechanistic evidence for their combined overlap remains scarce. This review synthesises current evidence on the epidemiological overlap and shared risk architecture linking MASLD, obesity and T2DM. We examine integrated pathophysiological and molecular mechanisms underpinning this triad, including insulin resistance, lipotoxicity, mitochondrial dysfunction, endoplasmic reticulum stress, transcriptional and epigenetic dysregulation and gut-liver axis perturbations. We further discuss the clinical implications of this shared biology, emphasising integrated screening strategies and presenting an evidence-based algorithm for non-invasive identification of advanced hepatic fibrosis within the triad. We review evidence-based therapeutic approaches, including mechanism-based pharmacological therapies, and highlight their differential effects on weight, glycaemic control and liver disease severity. Emerging research priorities and future directions for integrated cardiometabolic care are also outlined. Collectively, the review underscores the need for integrated hepatic-cardiometabolic care to improve clinical outcomes across this metabolic triad.\n\nID: 42392328\nTitle: Hierarchical analysis of metabolic phenotype reveals distinct microbiota and circulatory transcriptome in metabolic dysfunction-associated steatotic liver disease.\nAbstract: To investigate how visceral adiposity and insulin resistance, defined respectively by visceral adiposity index (VAI) and triglyceride-glucose (TyG) index, jointly influence gut microbiota composition and immune transcriptomes in metabolic dysfunction-associated steatotic liver disease (MASLD), and to explore potential mechanistic pathways. We enrolled 169 adults stratified by VAI, controlled attenuation parameter (CAP), TyG index, and physical activity. Gut microbiota and immune transcriptomes were profiled using 16S rRNA and RNA sequencing, respectively. Differentially expressed genes (DEGs) were identified across subgroups. Functional annotation and upstream regulatory networks were analyzed using DAVID and Ingenuity Pathway Analysis (IPA). Higher VAI correlated with obesity, inflammation, and steatosis, while the TyG index independently predicted fibrosis risk. Specific taxa, includingTM7x,Acidaminococcus, andDielma, were consistently enriched in adverse metabolic phenotypes. Transcriptomic analysis of circulating immune cells identified 348 TyG-associated DEGs significantly enriched in mitochondrial and cytokine signaling pathways. IPA highlighted IL6, SREBF1, PTGS1 and SNCA as central regulators linking metabolic stress to mitochondrial dysfunction. Gut microbiota shifts and immune transcriptome alterations jointly mediate the interplay between insulin resistance and visceral adiposity in MASLD. The identified insulin resistance-associated genes suggest that mitochondrial dysfunction and cytokine dysregulation contribute to obesity-related hepatic pathology, supporting precision strategies targeting VAI and metabolic dysregulation.\n\nID: 42389066\nTitle: Metabolic Dysfunction-Associated Fatty Liver Disease: From Pathogenesis to Treatment.\nAbstract: Metabolic dysfunction-associated fatty liver disease (MAFLD) has become the most prevalent chronic liver disease worldwide and represents a major hepatic manifestation of systemic metabolic dysfunction. The disease is closely linked to obesity and insulin resistance and progresses from simple hepatic steatosis to metabolic dysfunction-associated steatohepatitis, fibrosis, cirrhosis, and hepatocellular carcinoma. Increasing evidence indicates that MAFLD pathogenesis involves complex interactions among dysregulated lipid metabolism, mitochondrial dysfunction, oxidative stress, inflammatory signaling, bile acid imbalance, and gut microbiota-derived metabolites, reflecting the systemic and multifactorial nature of the disease. However, despite substantial progress in understanding these mechanisms, the integrated regulatory networks driving MAFLD progression and their translational therapeutic implications remain incompletely characterized. In this review, we comprehensively summarize recent advances in the molecular mechanisms underlying MAFLD, focusing on metabolic dysregulation, cellular stress responses, inflammatory pathways, and regulated cell death processes. We further highlight the critical role of interorgan communication particularly the adipose-liver and gut-liver axes and discuss emerging evidence on extracellular vesicles (EVs) as mediators of metabolic and inflammatory signaling. Finally, we evaluate current and potential therapeutic strategies, emphasizing the diagnostic and therapeutic promise of EV-based approaches in MAFLD management, and identifying emerging molecular targets for improved intervention and future clinical translation opportunities.\n\nID: 42388541\nTitle: Multi-target Mechanisms and Clinical Evidence for Ganzaoning Granule in Metabolic Dysfunction-Associated Steatotic Liver Disease: A Narrative Review.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly discussed largely under the non-alcoholic fatty liver disease (NAFLD) framework, is now one of the most common chronic liver diseases worldwide. Its progression from simple steatosis to metabolic dysfunction-associated steatohepatitis (MASH), fibrosis, cirrhosis, and hepatocellular carcinoma (HCC) reflects the interaction of lipid overload, insulin resistance, oxidative stress, immune activation, hepatic stellate cell activation, and oncogenic remodeling. Although resmetirom and glucagon-like peptide-1 receptor agonist-based strategies have recently advanced the treatment landscape for selected patients with MASH and fibrosis, many patients remain outside the indications of current drug therapy, and safe adjunctive strategies across earlier disease stages remain an unmet need. Ganzaoning granule is a traditional Chinese medicine formulation derived from the anti-HCC precursor formula Ganfujian and has been used clinically in China for fatty liver disease and related chronic liver conditions. This narrative review summarizes the available evidence on Ganzaoning, including its phytochemical profile, network pharmacology findings, preclinical studies, and clinical observations in MASLD/NASH populations. Existing studies suggest that Ganzaoning or its related active fractions may modulate lipid metabolism through the AMP-activated protein kinase (AMPK)/peroxisome proliferator-activated receptor gamma coactivator-1 alpha (PGC-1α) axis, attenuate inflammatory signaling involving nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kB) and advanced glycation end-product (AGE)-receptor for advanced glycation end-product (RAGE) pathways, and influence fibrosis- and hepatocarcinogenesis-related molecular processes. However, much of the mechanistic evidence remains preclinical or inferred from network pharmacology, and the clinical evidence is limited by single-center designs, short follow-up, composite endpoints, and limited use of histological or advanced imaging outcomes. We therefore position Ganzaoning as a biologically plausible candidate adjunctive therapy rather than an established MASLD treatment. Future research should prioritize standardized product quality control, pharmacokinetic and pharmacodynamic characterization, herb-drug interaction assessment, and multicenter, double-blind, placebo-controlled trials using accepted MASLD endpoints.\n\nID: 42387035\nTitle: Tirzepatide as a multi-organ integrator in metabolic diseases: a review of molecular mechanisms and clinical translation.\nAbstract: Metabolic diseases, including type 2 diabetes mellitus (T2DM), obesity, dyslipidemia, Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD), and obstructive sleep apnoea (OSA), are characterized by a complex and interconnected pathophysiological syndrome. These conditions involve insulin resistance, chronic inflammation, and disturbances in energy homeostasis. Typically, they affect multiple organs and require comprehensive treatment. This narrative review examines the multi-organ effects of tirzepatide, a new dual agonist of the glucose-dependent insulinotropic peptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors. Tirzepatide possesses innovative therapeutic properties and targets multiple metabolic pathways. The review incorporates peer-reviewed sources, including clinical trials, preclinical studies, and specialist reviews. Emphasis is placed on tirzepatide's physiological effects on pancreatic β-cells, adipose tissue, the liver, the gastrointestinal tract, the cardiovascular system, the kidneys, the brain, and gut microbiota. Tirzepatide is a dual receptor agonist that increases insulin levels, decreases glucagon levels, slows gastric emptying, and promotes feelings of fullness, contributing to significant weight loss. Recent preclinical studies have shown that tirzepatide can also alter gut microbiota composition, leading to increased Bacteroidetes and decreased Firmicutes. Additionally, tirzepatide has been shown to enhance intestinal barrier integrity. Clinical trial programs, such as SURPASS and SURMOUNT, have demonstrated that tirzepatide provides improved glycemic control and weight loss compared to current treatments. Other benefits include improvements in lipid profiles, reduced hepatic steatosis, and potential protection for the heart and kidneys. Tirzepatide is a multi-organ integrator with a therapeutic effect extending beyond glucose regulation. It can influence bowel hormones, improve metabolic parameters, and facilitate communication between different organs, making it a promising treatment for metabolic disorders. However, its broader clinical applications need to be confirmed through additional real-life studies and extended evaluations.\n\nID: 42433126\nTitle: A Modular Liver-Microbial Microfluidic Platform to Evaluate Therapeutic and Adverse Effects of Microbial Metabolites.\nAbstract: Gut microbial metabolites, particularly short-chain fatty acids (SCFAs) like butyrate, play a significant role in modulating non-alcoholic fatty liver disease (NAFLD). While animal studies show that butyrate-producing microbes can improve liver function, full recovery is hindered by unintended side effects from commensal bacteria. These underlying biomolecular mechanisms remain elusive, due to the lack of in vitro coculture models capable of systematically examine both the therapeutic benefits of engineered microbial metabolites and their potential adverse impacts. To address this, we developed a modular microfluidic platform to study the effects of live microbial metabolites on hepatic steatosis and liver function. We created a microfluidic-based hepatic steatosis model integrated with a compartmentalized microbial module, facilitating the study of how metabolites produced by live microbes affected the liver model. We compared the effects of synthetic SCFA supplementation with those of coculturing with a control and butyrate-producing E. coli Nissle 1917 (EcN) strains on hepatic steatosis. Our findings showed that live microbial coculture did not phenocopy exogenous SCFA treatment. While both treatments reduced steatotic lipid accumulation, live microbes induced inflammatory and hepatic metabolic changes, suggesting contributions from additional microbial factors, emphasizing the need to thoroughly assess side effects in liver disease treatment.\n\nID: 42429050\nTitle: Protective effects of Astragaloside IV on various liver diseases: From chemistry to herbal medicines (Review).\nAbstract: Numerous liver diseases are characterized by late diagnosis, rapid progression and high incidence, seriously threatening public health. Though widely used, traditional treatments such as drug therapy, resection and transplantation have substantial limitations. Therefore, developing novel preventive strategies and specialized therapies is crucial. As Chinese medicine continues to modernize, increasing evidence suggests that certain Chinese medicine ingredients can protect the liver. Astragaloside IV (AS‑IV) is a natural saponin extracted from the root of the traditional herb Astragalus membranaceous. It exhibits diverse pharmacological activities, including anti‑inflammatory, antioxidant, antiapoptotic and anticancer properties, and is recognized for treating neurological, cardiovascular and metabolic disorders, and cancer. These discoveries indicate its substantial promise for the treatment of liver diseases. Therapeutic trials revealed its hepatoprotective effects for the treatment of various liver diseases, such as non‑alcoholic fatty liver disease, liver fibrosis, hepatocellular carcinoma and liver injury induced by heavy metals, drugs, or alcohol and involve various signaling pathways such as nuclear factor erythroid 2‑related factor 2, toll‑like receptor 4, acetyl‑CoA carboxylase, protein kinase B, nuclear factor κB and adenosine monophosphate‑activated protein kinase. The present study presents a narrative review that comprehensively summarizes existing evidence regarding the therapeutic influence of AS‑IV on diverse liver disorders and deeply analyzes the molecular mechanisms underlying its action in liver disease. The objective is to comprehensively offer insights and references for relevant scientific research and clinical drug development to improve nutritional supplements for liver health.\n\nID: 42421922\nTitle: Sinensetin ameliorates established high-fat diet-induced liver injury and intestinal barrier dysfunction through the mitophagy/TLR4/MAPK signaling pathway.\nAbstract: Long-term consumption of a high-fat diet (HFD) causes liver injury characterized by steatosis, inflammation, and fibrosis. Mitophagy, as a selective autophagy, is reported to be involved in the regulation of liver injury. Sinensetin, a polymethoxylated flavonoid abundant in citrus fruit peels, exhibits various biological activities, including anti-inflammatory and hepatoprotective properties. However, whether sinensetin can target mitophagy and protect against HFD-induced liver damage via the gut-liver axis remains inadequately explored. In order to further investigate the relationships involved, we conducted histopathology analysis, biochemical analysis, 16S rRNA sequencing, and short-chain fatty acid (SCFA) levels. Sinensetin administration ameliorated hepatic steatosis, inflammation, and restored intestinal integrity in HFD-fed mice. Mechanistically, sinensetin remodeled the gut microbiota, elevating SCFA levels, which activated mitophagy and cleared damaged mitochondria in liver and intestinal tissues, thereby suppressing the toll-like receptor 4 (TLR4)/mitogen-activated protein kinase (MAPK) signaling. Sinensetin may contribute to protecting against HFD-induced liver injury and intestinal barrier dysfunction by orchestrating the integrated \"microbiota-SCFA-mitophagy\" defensive network, providing a novel paradigm beyond the classical TLR4/MAPK axis.\n\nID: 42416830\nTitle: Therapeutic potential and mechanisms of flavonoids from Citrus grandis 'Tomentosa' in metabolic dysfunction-associated steatotic liver disease: a focus on immune-inflammatory signaling pathways.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) constitutes a major global health burden, with limited therapeutic options currently available. Flavonoids derived from natural plants exhibit promising antioxidant and anti-inflammatory bioactivities, making them potential preventive and therapeutic agents for metabolic liver diseases. Citrus grandis 'Tomentosa' (CGT) flavonoids have shown hepatoprotective properties in preliminary preclinical investigations. However, a systematic and critical evaluation of the preclinical evidence supporting their application in MASLD, particularly regarding immune-inflammatory regulatory mechanisms, remains absent. This scoping review aimed to comprehensively map and critically appraise preclinical studies concerning the efficacy and molecular mechanisms of CGT flavonoids in MASLD, with a specific focus on immune-inflammatory signaling modulation. A scoping review methodology was applied to synthesize current preclinical evidence on CGT flavonoids for MASLD. Following standardized literature retrieval and screening procedures, a total of 22 eligible studies were included for qualitative evidence synthesis. The pharmacological effects, mechanistic findings, and methodological limitations of existing studies were systematically summarized and critically assessed. Synthetic analysis of the included studies demonstrated that CGT flavonoids effectively ameliorate hepatic steatosis, inflammatory responses, and oxidative stress in experimental MASLD models. The underlying mechanisms are preliminarily associated with the modulation of NF-κB, MAPK, and JAK-STAT signaling pathways, as well as the regulation of immune cell polarization. Nevertheless, most mechanistic evidence remains indirect and inconclusive, largely derived from non-CGT preparations or non-MASLD models, with a lack of direct target validation. The current body of evidence presents critical research gaps, including potential experimental artifacts caused by pan-assay interference, insufficient pharmacokinetic profiling, and inadequate rigorous studies validating CGT-specific regulatory effects on hepatic immune components, such as Kupffer cells and intrahepatic T-cell subsets under MASLD pathological conditions. The present scoping review confirms the preclinical potential of CGT flavonoids as novel botanical candidates for MASLD treatment, primarily through the suppression of hepatic steatosis, oxidative damage, and immune-inflammatory activation. However, existing evidence is methodologically limited and insufficient to support clinical translation. To address current deficiencies and facilitate translational progress, further rigorous mechanistic validation, standardized CGT flavonoid preparation protocols, and well-designed clinical investigations are urgently required. This work provides a balanced, evidence-based, and critical framework to guide future basic research and translational studies targeting CGT flavonoids for MASLD intervention.\n\nID: 42410322\nTitle: Identification and Characterization of Novel Anti-inflammatory and Hepatoprotective Properties of Dual-Function Peptides Derived from Jinhua Ham: A Study Integrating Computational Modeling with the cGAS-STING Pathway.\nAbstract: The development of bioactive peptides derived from food is crucial for alleviating nonalcoholic fatty liver disease. As a traditional meat product, Jinhua ham is rich in various bioactive peptides and has anti-inflammatory and liver-protective effects. This study aims to isolate novel dual-function peptides with anti-inflammatory and hepatoprotective properties from Jinhua ham hydrolysates. Potential target peptides were identified through mass spectrometry and computational virtual screening, followed by molecular docking and molecular dynamics simulations. In vitro, 1 mg/mL of NWRPPQPIK (NW-9) reduced AST, ALT, IL-1β, IL-6, and TNF-α levels by 51.66%, 54.08%, 24.66%, 33.71%, and 15.79%, respectively. In vivo, NW-9 also demonstrated therapeutic effects. This is because NW-9 can alleviate liver inflammatory damage caused by the cGAS-STING pathway. These findings provide a theoretical basis for the development of Jinhua ham-derived dual-function peptides with anti-inflammatory and hepatoprotective properties in the functional food industry, further expanding the high-value utilization of food-derived bioactive peptides.\n\nID: 42404798\nTitle: Synergistic modulation of the gut microbiome-liver-host metabolome axis associates with the therapeutic efficacy of Danlou tablet against metabolic syndrome.\nAbstract: Obesity drives chronic diseases such as cardiovascular disease and diabetes. Danlou tablet (DLT), a traditional Chinese medicine formula, is used to treat coronary heart disease by regulating lipid metabolism, suggesting potential for addressing obesity-related metabolic dysfunction. However, its role in obesity and insulin resistance remains unexplored. We investigated the efficacy and mechanisms of DLT against high-fat diet (HFD)-induced obesity and insulin resistance. C57BL/6N mice were fed an HFD for 22 weeks and treated with DLT. A comprehensive phenotypic assessment was conducted, including body weight, glucose tolerance, insulin sensitivity, serum biochemistry, and histopathology of key tissues. To elucidate the therapeutic mechanism, we integrated 16S rRNA gene sequencing of gut microbiota, serum metabolomics (UPLC-Q-TOF-MS), and hepatic transcriptomics. DLT treatment counteracted HFD-induced metabolic dysfunction, reducing body weight, adiposity, dyslipidemia, and insulin resistance, while ameliorating hepatic steatosis, inflammation, and oxidative stress. At the microbial level, DLT restored gut microbial diversity, corrected the Firmicutes/Bacteroidota ratio, and modulated key genera. Metabolomics linked these changes to restored fatty acid β-oxidation. In the liver, transcriptomics showed that DLT reversed HFD-induced gene expression, suppressed inflammatory pathways and enhanced fatty acid oxidation and xenobiotic metabolism. Integrated multi-omics analysis revealed a strong correlative relationship that DLT's therapeutic benefits are associated with the modulation of the gut-liver axis, where remodeling of the gut microbiome is closely linked to the reprogramming of hepatic metabolic pathways. DLT counteracts HFD-induced obesity and insulin resistance via a multi-level regulatory mechanism that is closely associated with the modulation of the gut-liver axis, which involves suppressing pathogenic gut microbes, restoring fatty acid metabolism, and enhancing hepatic lipid catabolism and antioxidant defense. This comprehensive preclinical evidence supports the clinical translation of DLT as a novel therapeutic option for obesity and type 2 diabetes mellitus.\n\nID: 42404787\nTitle: The gut microbiota-bile acid axis in liver transplantation: implications for postoperative complications and therapeutic strategies.\nAbstract: Liver transplantation (LT) is a critical intervention for end-stage liver disease, while complications, such as infections, graft rejection, and metabolic disturbances are common post-transplant. The gut microbiota-bile acid (GM-BA) axis plays a pivotal role in regulating liver function and overall health, influencing both the gut microbiota and bile acid metabolism. This review explored the complex interplay between the gut microbiota (GM) and bile acids during liver transplantation. It also discussed how disruptions in this axis can lead to post-transplant complications, such as infection, rejection, and liver injury. Specifically, the role of microbiota-derived bile acids was assessed in shaping immune responses and metabolic pathways that may impact liver graft function. Furthermore, therapeutic strategies aimed at modulating the GM-BA axis were reviewed to improve post-transplant outcomes, including the use of probiotics, prebiotics, and bile acid receptor modulators. Understanding the mechanisms behind GM-BA dysregulation may provide new directions for improving liver transplant survival and reducing complications.\n\nID: 42403914\nTitle: Intestinal neutral ceramidase, microbial metabolites and epithelial fucosylation in MASH.\nAbstract: \n\nID: 42395745\nTitle: Aqueous extract of Duyun Maojian tea ameliorates the ileal microbiota and associated hepatic metabolome in HFD-induced obese mice.\nAbstract: Duyun Maojian tea (DYMJ), a renowned Chinese green tea, exhibits potential anti-obesity properties, though its mechanisms remain unclear. This study investigated DYMJ's regulatory effects using a high-fat diet (HFD)-induced obese mouse model, with Xuezhikang (XZK) as a positive control (HP). Hepatic/serum biochemical parameters, histopathology, liver metabolomics and ileal microbiota were analyzed. DYMJ significantly reduced body weight, hepatic malondialdehyde, aminotransferase activity and steatosis while enhancing superoxide dismutase activity. Gut microbiota analysis revealed that HFD-induced Firmicutes phylum related to energy dysregulation and insulin resistance was modulated by DYMJ. Notably, Anaerotruncus genus abundance was positively correlated with pyridoxal 5'-phosphate level. In contrast, XZK increased the abundance of Proteobacteria, potentially exacerbating insulin resistance despite improving energy metabolism. DYMJ treatment restored microbial balance closer to normal-diet (ND) conditions, particularly by elevating nicotinic acid adenine dinucleotide and enriching Bacteroidetes phylum species associated with metabolic health. These findings suggested that DYMJ mitigated obesity through dual mechanisms: alleviating oxidative stress and hepatic lipid accumulation, while reshaping gut microbiota toward a metabolic health-promoting composition. This study supports DYMJ as a safe dietary supplement for body weight management, and highlights the gut-liver axis as a pivotal target for addressing metabolic disorders.\n\nID: 42395007\nTitle: Korean red ginseng extract ameliorates high-fat diet-induced hyperlipidemia by modulating the gut microbiota-liver metabolic axis.\nAbstract: Korean Red Ginseng is recognized for its ability to modulate immune responses, alleviate fatigue, and combat aging, and shows promise in treating hyperlipidemia. However, comprehensive insights into its gut-liver axis mechanisms remain limited. Rats were assigned to a normal control group, an HFD-fed model group, and four groups treated with Korean Red Ginseng extract (RGE) at doses of 125 mg/kg, 250 mg/kg, 500 mg/kg, and 1000 mg/kg. The treatment groups administered RGE by gavage for 60 days while on an HFD. The study evaluated RGE's effects on hyperlipidemia and gut microbiota through serum biochemical analysis, hepatic histopathology, cecal metabolomics, 16S rRNA sequencing, and further investigated hepatic regulatory mechanisms using molecular biology techniques. After 60 days of treatment, RGE significantly reduced serum lipid levels and liver injury markers. Histological analysis using H&E and Oil Red O staining showed that RGE significantly reduced hepatic steatosis in comparison to the model group. LC-MS and 16S rRNA sequencing of cecal contents revealed that RGE remodeled gut microbiota composition, enhancing microbiota-derived metabolite production. Molecular analysis indicated that RGE activated hepatic PPARα, downregulated SREBP-1c, and partially restored basal cholesterol biosynthesis by upregulating HMGCR mRNA. These changes collectively reduced hepatic triglyceride accumulation and promoted cholesterol excretion. RGE alleviates HFD-induced hyperlipidemia and hepatic steatosis through a coordinated gut-liver axis mechanism, involving microbiota modulation, metabolic reprogramming, and regulation of hepatic lipid factors. These findings support RGE as a potential therapeutic option for hyperlipidemia and related metabolic disorders, using an \"excretion-centric\" strategy.\n\nID: 42388647\nTitle: Astaxanthin Vesicles Improve Alcoholic Liver Disease Through Oxidative Stress and NF-κB Inflammatory Pathway.\nAbstract: Liver injury induced by alcoholic fatty liver disease (ALD) will eventually lead to the development of hepatocellular carcinoma. The antioxidant and anti-inflammatory functions of astaxanthin (AST) can prevent and alleviate liver injury. In this study, AST was embedded in fatty acid vesicles to determine the effects of astaxanthin vesicles (AST-FAV) on ALD. The results demonstrated that compared to free AST, AST-FAV improved liver fat accumulation and oxidative damage caused by excessive drinking, and inhibited the production of pro-inflammatory cytokines by regulating the TLRs/MyD88/NF-κB, TNF-α/TNFR/NF-κB, and NLRP3/NF-κB pathways. In summary, AST-FAV can exert its anti-inflammatory effect through antioxidation and multiple pathways to prevent liver injury. These findings not only highlight the potential of AST-FAV for application in functional foods or dietary supplements but also provide a theoretical basis for further exploration of its potential as a clinical intervention strategy for the prevention or adjunctive treatment of alcoholic liver disease in humans.\n\nID: 42388495\nTitle: The impact of gut microbiome on intrahepatic cholestasis of pregnancy-systematic literature review.\nAbstract: In recent years, there has been a growing interest in the gut microbiome and its potential role in the etiopathogenesis of both gastrointestinal and extraintestinal diseases. Dysbiosis, characterized by a pathological alteration in the composition of the gut microbiome, has been implicated in various gastrointestinal diseases. This paradigm extends to pregnancy-specific conditions, including intrahepatic cholestasis of pregnancy (ICP). ICP exhibits a multifactorial etiopathogenesis, involving hormonal, genetic and environmental factors, among others. Despite growing scientific evidence, there is currently a lack of comprehensive reviews that specifically examine the causal mechanisms through which gut microbiota dysbiosis might contribute to the pathogenesis of ICP, as well as the resulting implications for the development of new targeted therapeutic approaches. Notably, shifts in microbial taxa and the depletion of bacteria involved in certain metabolic pathways have been observed in ICP. These findings suggest that alterations in the gut microbiome composition may contribute to the pathophysiology of ICP. Such microbiome-associated alterations may have important implications for risk stratification and early identification of patients at increased risk of adverse maternal and fetal outcomes. Further investigation into these microbial changes and molecular pathways could offer novel insights and identify potential pharmacological targets for ICP development and management. In particular, modulation of the gut microbiome could represent a future adjunctive strategy to existing therapeutic approaches, potentially improving disease monitoring and individualized management. The precise role of gut microbiome composition in the management and treatment of ICP is still not fully understood, highlighting the need for a systematic review to synthesize existing evidence and identify critical gaps relevant to the future development of screening, prevention, and targeted therapeutic strategies.\n\nID: 42387267\nTitle: Review Article: The Impact of the Gut Microbiome on Ulcerative Colitis Pharmacotherapy.\nAbstract: Ulcerative colitis (UC) is a chronic immune-mediated condition of the gastrointestinal tract with highly variable treatment responses. Current therapies focus on suppressing inflammation through aminosalicylates, corticosteroids, immunomodulators, biologics, and small molecules, yet many patients experience suboptimal outcomes, including non-response, partial response, or loss of efficacy over time. This variability has prompted increasing attention to the gut microbiome as a contributing factor. This review aimed to compile the current evidence on how the gut microbiome modulates the efficacy and pharmacokinetics of UC therapies, including mechanisms of microbial drug metabolism and host-microbe interactions that affect immune regulation. Clinical and preclinical studies exploring the role of the microbiome in UC pharmacotherapy were identified through targeted PubMed and Embase searches. Microbial communities in the gut alter UC drug exposure and action by metabolising active compounds, modifying the host immune response, and influencing local drug absorption and clearance. Differences in microbiome composition and function between individuals may explain some of the heterogeneity in drug response, durability and adverse effect profiles. Clinical studies now show that microbiome characteristics at baseline can correlate with UC treatment outcomes and may even predict therapeutic response. Understanding these microbiome-drug relationships may improve the precision of UC therapy, support the development of microbiome-guided interventions, and inform future drug development and clinical trial design. Recognising the microbiome as an active variable in treatment response reframes pharmacology in UC as not only drug- and host-dependent but also shaped by the dynamic microbial environment of the gut.\n\nID: 42385885\nTitle: Alcohol and high-fat diet aggravate colitis-induced liver injury via glucocorticoid/IL-6-SAA1 axis in mice.\nAbstract: Colitis-associated liver injury rarely causes acute mortality, but whether alcohol and a high-fat diet (HFD) aggravate hepatic injury during colitis remains unclear. Here, dextran sulfate sodium (DSS)-induced colitic mice were exposed to alcohol, HFD, or both. Compared with DSS alone, combined HFD and alcohol exposure (DSSHA) caused greater body-weight loss, poorer body condition, and reduced survival. These effects were linked mainly to liver rather than intestinal deterioration, as shown by an increased liver/body-weight ratio, elevated serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST), and severe hepatic steatosis, whereas colon length, colon weight, and intestinal histological injury were not further aggravated. Mechanistically, alcohol-HFD co-exposure impaired the gut-liver axis, reduced intestinal tight-junction proteins, increased gut permeability and circulating lipopolysaccharide (LPS), and promoted hepatic macrophage and neutrophil infiltration with increased interleukin-6 (IL-6). Transcriptomics identified serum amyloid A1 (SAA1) as a highly upregulated acute-phase gene and revealed Toll-like receptor 4 (TLR4) pathway enrichment. TLR4 inhibition TAK-242 significantly improved survival and attenuated liver injury. Multi-omics further showed increased hepatic cortisol and corticosterone, which cooperated with IL-6 to induce SAA1 expression in HepG2 cells. Thus, an IL-6/glucocorticoid-SAA1-TLR4 axis drives alcohol-HFD-aggravated liver injury in colitis and may represent a therapeutic target.\n\nID: 42385714\nTitle: Gut commensal Bacteroides-derived pantothenic acid alleviates metabolic syndrome.\nAbstract: Pantothenic acid (PA), or vitamin B5, can be synthesized by gut commensals, but the contribution of microbial PA to metabolic health remains unclear. Here, we find that microbial PA supply is reduced in individuals with metabolic syndrome (MetS) and is associated with impaired gut barrier function and disease severity. Tracing microbial PA identifies Bacteroides fragilis as a key contributor, with panC required for PA biosynthesis, as confirmed by isotope tracing, bacterial culture, and germ-free colonization. In MetS models, colonization with wild-type, but not ΔpanC B. fragilis, restores PA, preserves gut barrier integrity, reduces endotoxemia, and improves metabolic dysfunction. Mechanistically, microbial PA requires host pantothenate kinase activity, as silencing pantothenate kinase 2/3 (PANK2/3) in colonic organoids and in vivo reduces coenzyme A (CoA)/acetyl-CoA metabolism, suppresses Krüppel-like factor 4 (KLF4)-associated differentiation programs, and blunts the protective effects of microbial PA. Finally, a plant-derived polysaccharide enriches PA-producing Bacteroides and restores colonic PA, highlighting a strategy for colonic homeostasis and metabolic health.\n\nID: 42385626\nTitle: More efficient and precise toward application of tomato-derived lycopene: a state-of-the-art review into sources, chemistry, extraction methods, bioavailability, and uniting power in fatty liver disease.\nAbstract: Fatty liver disease (FLD) is among the most prevalent chronic liver disorders worldwide. Tomato-derived lycopene has received considerable attention as a functional bioactive compound due to its strong antioxidant and anti-inflammatory effects on molecular pathways associated with FLD progression. Nevertheless, an integrated assessment of lycopene sources, chemistry, extraction technologies, stability, and functional efficacy remains limited. Lycopene bioavailability is restricted by its lipophilic nature and instability during food processing and gastrointestinal digestion. Degradation pathways including photo-oxidation, thermal trans-cis isomerization, and oxidative cleavage are intensified during high-temperature drying (>70 °C), prolonged storage, light exposure, and oxygen-rich processing conditions, resulting in reduced stability and biological activity. Advanced emerging delivery systems such as nanoencapsulation, nanoemulsions, and lipid-based carriers have shown promising improvements in lycopene protection, absorption, and efficacy. Future approaches including biofortification, personalized nutrition, and synergistic formulations may support the development of innovative functional foods for FLD prevention and management.\n\nID: 42385432\nTitle: Polyphenols extracted from Lycium barbarum seeds regulate gut microbiota to improve type 2 diabetes mellitus in db/db mice.\nAbstract: Mounting evidence positions the gut microbiota as a pivotal player in the onset and progression of type 2 diabetes mellitus (T2DM). Lycium barbarum seed polyphenols (LBSPs), a byproduct of Lycium barbarum processing, have shown antioxidant and anti-inflammatory bioactivities, but potential anti-T2DM effects remain unclear. To evaluate the preventive effects of LBSPs against T2DM and the associated gut microbiota mechanisms. The effects of LBSPs on fasting blood glucose, insulin sensitivity, liver lipid accumulation, intestinal barrier, gut microbiota composition, and microbial metabolites were investigated in db/db mice. LBSPs significantly reduced fasting blood glucose, improved insulin sensitivity, and alleviated dyslipidemia and hepatic steatosis in db/db mice. Furthermore, LBSPs restored intestinal barrier integrity by up-regulating tight junction proteins Claudin-1, Occludin, and Zonula Occludens-1 (ZO-1). 16S rRNA analysis revealed that LBSPs reversed gut microbiota dysbiosis, enriching Lactobacillus, Ligilactobacillus, Rikenella, Lachnospiraceae_NK4A136_group, while decreasing Escherichia-Shigella and Klebsiella. Mechanically, LBSPs can modulate aromatic amino acid metabolism, lipid metabolism, and bile acid biosynthesis by metabolomics. Mediation analysis indicated that specific gut microbiota influenced host metabolic parameters through metabolites such as 7-megastigmene-3,6,9-triol 9-glucoside. Our findings reveal that LBSPs can be used as a potential microbiota-targeted nutraceutical that reverses gut microbiota dysbiosis and diabetes-associated metabolic disorders during T2DM progression.\n\nID: 42423485\nTitle: The Role of Gut Microbiota in Liver Regeneration After Partial Hepatectomy: New Evidence From Animal and Human Studies.\nAbstract: Liver regeneration is increasingly recognized as a process influenced not only by hepatocellular signaling but also by the gut-liver axis, where gut microbiota-derived metabolites, immune mediators, and extracellular vesicles modulate hepatic recovery after liver damage. In this review, we explore recent progress in understanding the gut microbiota's role in liver regeneration and discuss its therapeutic potential in the context of hepatic surgery and liver transplantation. Emerging evidence shows that beneficial microbial taxa, including Akkermansia muciniphila, Bifidobacterium longum, and Parabacteroides distasonis, enhance liver regeneration by regulating short-chain fatty acid production, bile acid metabolism, and tricarboxylic acid cycle pathways, while dysbiosis and microbial translocation can impair regenerative outcomes. Key host-microbiome interactions, particularly the Farnesoid X Receptor (FXR)-Fibroblast Growth Factor 19 (FGF19) signaling axis, play a central role in protecting hepatocytes from bile acid overload and supporting regeneration, highlighting the therapeutic potential of FXR agonists, FGF19 mimetics, probiotics, dietary interventions, and metabolite supplementation. At the same time, monitoring bile acids profiles alongside gut microbiota composition may allow early detection and prevention of complications. In addition, microbial-derived markers such as the lipopolysaccharide/lipoteichoic acid ratio may serve as predictive biomarkers for post-hepatectomy liver failure. Adjunctive approaches, including vitamin D supplementation, may further support regeneration through vitamin D receptor-mediated regulation of bile acid homeostasis and cell-cycle progression. In the context of live donor liver transplantation, the detection of occult bacteremia further underscores the complexity of host-microbiome interactions and suggests that microbiological surveillance could improve postoperative management. Collectively, these findings emphasize the importance of microbiota-targeted strategies to improve hepatic regeneration, reduce postoperative complications, and optimize outcomes following liver surgery and transplantation.\n\nID: 42377574\nTitle: Butyrate ameliorates maternal high-fat-diet-induced placental inflammation and offspring metabolic dysfunction via modulating gut microbiota in mice.\nAbstract: Maternal high-fat diet (HFD) increases the risk of metabolic disorders in offspring. Placental inflammation acts as a critical mediator with poorly addressed etiology. Recently HFD-induced gut dysbiosis is demonstrated to be a key driver of systemic inflammation. Whether inflammatory signals triggered by HFD-induced gut dysbiosis are transmitted to the placenta via the maternal-fetal axis warrant further investigation. This study aims to elucidate the mechanistic connection between maternal gut dysbiosis and placental inflammation, thereby offering insights into microbiota-mediated developmental origins of metabolic diseases in offspring. Female C57BL/6 mice were exposed to high fat diet (HFD) for 5 weeks prior to mating with male mice. Gut microbiota was profiled by using 16 S rRNA sequencing and fecal short-chain fatty acids (SCFAs) were quantified by GC-MS from HFD pregnant mice at gestational day 18.5 (G18.5). Mice were sacrificed at G18.5, and placenta histopathological analysis as well as inflammatory markers and lipopolysaccharide (LPS) level were analyzed. Anti-inflammatory effects of butyrate were evaluated in vitro by using HTR-8/Svneo cells and in vivo through gestational supplementation (0.3 mg/g body weight) in HFD-fed dams. Maternal HFD exposure induced significant placental inflammation as well as hepatic steatosis in the offspring. HFD-fed dams exhibited distinct gut dysbiosis with reduced fecal and serum SCFAs, which was accompanied by elevated placental LPS levels and exacerbated inflammatory responses. Butyrate treatment suppressed the expression of inflammatory cytokines in vitro through down-regulating the phosphorylation of NF-κB, ERK1/2 signaling pathways via G-protein-coupled receptor 41 (GPR41). Furthermore, gestational butyrate intervention effectively alleviated placental inflammation and mitigated fetal hepatic lipid deposition in HFD-exposed offspring. Placental inflammation caused by maternal HFD is closely associated with gut microbiota dysbiosis. Butyrate supplementation during gestation reduces placental inflammation and ameliorated offspring hepatic steatosis, highlighting the therapeutic potential of butyrate for mitigating the adverse metabolic programming effects upon maternal HFD exposure.\n\nID: 42368343\nTitle: Dietary supplementation with walnut (Juglans regia L.) green husk polyphenol extract mitigates fatty liver hemorrhagic syndrome in laying hens.\nAbstract: Extracts derived from the walnut (Juglans regia L.) green husk exhibit a variety of biological activities. This study investigated the effects of walnut green husk polyphenol extracts (WGHPE) on fatty liver hemorrhagic syndrome (FLHS)-related indicators, antioxidant performance, and cecal microbiota modulation in laying hens. A total of 350 Hy-Line Brown laying hens aged 43 weeks were randomly assigned to five groups with seven replicates per group and 10 hens per replicate. An FLHS model was induced via intramuscular injection of β-estradiol dissolved in corn oil. The control (Con) and FLHS model groups received a basal diet, whereas three FLHS-based treatment groups were fed the basal diet supplemented with 0.5% (WGHPEL), 1.0% (WGHPEM), or 1.5% (WGHPEH) WGHPE, respectively. All laying hens had unrestricted access to food and water throughout the 8-week experimental period. Compared with the FLHS group, dietary supplementation with WGHPE significantly reduced liver weight, liver coefficient, abdominal adipose weight, and abdominal adipose coefficient. Histological evaluation demonstrated that WGHPE alleviated hepatocellular vacuolar degeneration and lipid droplet accumulation, indicating an improvement in FLHS-related pathological features. Furthermore, WGHPE significantly reversed FLHS-induced elevations in serum levels of total cholesterol, aspartate aminotransferase, alanine aminotransferase, and low-density lipoprotein cholesterol. WGHPE also enhanced systemic antioxidant capacity by increasing catalase and total superoxide dismutase activities in β-estradiol/corn oil-induced laying hens, while decreasing malondialdehyde levels. Regarding intestinal health, WGHPE significantly increased villus height and the villus-to-crypt ratio in the jejunum and ileum. Furthermore, in the WGHPE treatment group, the relative abundance of beneficial bacterial taxa was increased. Campylobacter and Parasutterella were positively correlated with body weight and abdominal adipose deposition, whereas Desulfovibrio and unclassified_Oscillospiraceae showed negative correlations. These findings collectively indicate beneficial associations between dietary WGHPE supplementation, intestinal microbiota composition, and overall health status in laying hens with FLHS. Dietary supplementation with WGHPE mitigated β-estradiol/corn oil-induced FLHS-associated liver injury, enhanced antioxidant capacity, and improved intestinal morphology and microbial composition. A supplementation level of 1.5% WGHPE is recommended for optimal efficacy.\n\nID: 42364524\nTitle: Gut microbiota dysbiosis in chronic liver disease: Mechanisms driving hepatocellular carcinoma progression and therapeutic implications of Chinese medicine.\nAbstract: Chronic liver disease represents a major global public health challenge, and its malignant progression to hepatocellular carcinoma is the leading cause of death among affected patients. Gut microbiota dysbiosis is a critical driver of this process. As the central hub of the \"gut-liver axis,\" the gut microbiota, when disrupted, compromises the integrity of the intestinal mucosal barrier, promoting the translocation of microbial metabolites, such as lipopolysaccharides and aberrant secondary bile acids, to the liver. In turn, key signaling pathways become activated, including TLR4/NF-κB, Wnt/β-catenin, and PI3K/Akt, sustaining persistent hepatic inflammation and oxidative stress. These pathological processes accelerate the progression from liver fibrosis to cirrhosis, promote genomic instability, and suppress tumor suppressor gene expression, paving the way for the malignant transformation of hepatocytes. Leveraging its holistic regulatory properties, characterized by multi-component, multi-target, and multi-pathway actions, Chinese medicine can intervene at multiple stages of this inflammation-to-cancer cascade by modulating both the structure and function of the gut microbiota. It does so first by enriching beneficial short-chain fatty acid-producing bacteria, such as Lactobacillus and members of the phylum Firmicutes, which helps restore the intestinal mucosal barrier, limit endotoxin translocation, and alleviate hepatic inflammation and fibrosis. In parallel, by normalizing bile acid metabolism and reestablishing gut microbial homeostasis, Chinese medicine counteracts the development of a tumor-permissive microenvironment marked by immune suppression and DNA damage in hepatocytes induced by microbial metabolites. At the same time, it enhances anti-tumor immune responses mediated by CD8+ T cells and other immune effectors. Drawing on evidence from multi-omics analyses and clinical studies, this review examines the core mechanisms and recent advances regarding how Chinese medicine monomers and formulations modulate the gut microbiota to impede the progression of chronic liver disease to HCC. It highlights gut microbiota dysbiosis as a key driver of hepatocarcinogenesis and highlights the therapeutic potential of targeted microbiota regulation by Chinese medicine, providing a conceptual foundation and strategic approaches for the precision prevention and treatment of hepatocellular carcinoma.\n\nID: 42358148\nTitle: [Research progress on the role of the microbiota-gut-liver axis immune pathway in metabolic dysfunction-associated steatotic liver disease].\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a widely prevalent chronic liver disease that presents significant challenges to public health and medical care worldwide, yet its underlying mechanisms remain incompletely understood. The gut microbiome plays a crucial role in MASLD. Liver inflammation is a key factor in the onset and progression of this disease, and the gut microbiota significantly influences the liver's immune system and inflammatory responses. This article aims to review how both pro-inflammatory and anti-inflammatory gut microbes regulate liver inflammation by activating liver immunity and enhancing liver immune protection, respectively, through the microbiota-gut-liver axis. This review seeks to provide valuable insights for the improvement and treatment of MASLD.\n\nID: 42358145\nTitle: [Research progress on the mechanism of hyodeoxycholic acid in the treatment of MASLD through the gut-liver axis].\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a metabolic liver disorder affecting over 30% of the global adult population, with its prevalence and mortality rates continuing to rise. Hyodeoxycholic acid (HDCA), a natural secondary hydrophilic bile acid and the primary active component of traditional Chinese medicine Sus scrofa gallbladder powder, has been demonstrated by multiple studies to ameliorate MASLD and other hepatic metabolic disorders, potentially exhibiting superior efficacy to metformin. This review systematically discusses the multifaceted regulatory mechanisms of HDCA on glucose metabolism, lipid metabolism, and inflammatory responses in the gut-liver axis and peripheral tissues through its interactions with bile acid receptors including farnesoid X receptor (FXR), Takeda G protein-coupled receptor-5 (TGR5), liver X receptor (LXR) and with gut microbiota. The paper aims to provide theoretical foundations and therapeutic targets for the safe treatment of MASLD and metabolic dysfunction-associated steatohepatitis (MASH).\n\nID: 42353191\nTitle: Akkermansia muciniphila Alleviates Enterococcus faecalis-Exacerbated Alcoholic Liver Injury by Modulating Gut Microbiota and Barrier Function.\nAbstract: Cytolysin-positive Enterococcus faecalis is a key pathogen in severe alcoholic hepatitis, yet the mechanisms through which it worsens disease and possible therapeutic strategies remain poorly understood. This study aimed to clarify the pathogenic effects of E. faecalis in acute alcohol-associated liver disease (ALD) and to assess the protective potential of Akkermansia muciniphila (Akk11) against this pathogen. Using a mouse model of acute ethanol gavage, animals received E. faecalis and/or Akk11 under prophylactic or therapeutic regimens. Assessments included liver injury markers, histopathology, lipid profiles, inflammatory cytokines, gut barrier integrity, and gut microbiota composition. E. faecalis exacerbated ethanol-induced hepatic steatosis and injury, showing a paradoxical effect: it increased histological damage while lowering circulating LPS and transaminases. This was linked to upregulated hepatic autophagy (increased Atg7) and reduced cholesterol, yet it promoted neutral lipid accumulation. Importantly, E. faecalis aggravated gut dysbiosis by markedly enriching the pro-inflammatory pathobiont Helicobacter typhlonius and impairing colonic barrier function. Intervention with Akk11 alleviated liver injury, reduced lipid accumulation and oxidative stress, and restored cytokine balance. Akk11 also strengthened gut barrier integrity, lowered serum endotoxin, and beneficially reshaped the microbiota. Prophylactic administration was particularly effective, normalizing the Firmicutes/Bacteroidota ratio, suppressing H. typhlonius, and enriching beneficial Bacteroides sartorii. This study confirms the pathogenic role of E. faecalis in acute ALD and establishes A. muciniphila (Akk11) as a promising microbiota-targeted therapy, which protects against liver injury by reinforcing the gut barrier, selectively modulating microbiota, and reducing inflammation, with prophylactic administration showing superior efficacy.\n\nID: 42349829\nTitle: Novel genetic insights into causal effects of depression on non-alcoholic fatty liver diseases partially mediated by gut microbiota.\nAbstract: Depression and non-alcoholic fatty liver disease (NAFLD) are increasingly recognized as interconnected disorders, yet the causal mechanisms linking them remain unclear. Using univariable and multivariable Mendelian randomization (MR), we demonstrated that depression causally increased the risk of NAFLD (P = 8.473 × 10-8, OR = 1.944, 95% CI: 1.524 to 2.479), independent of major metabolic confounders. Mediation analysis further identified the gut microbial genus Phascolarctobacterium as a partial mediator of this effect (P = 0.0328, β = 0.145, 95% CI: 0.0119 to 0.278), with a mediated proportion of 21.818%. By integrating genetic mapping, transcriptomic profiling, and machine learning, we identified MICAL2 as a central hub gene linking depression-associated genetic variation to NAFLD. Furthermore, single-cell analysis revealed MICAL2-associated gene signatures are linked to macrophage dysfunction in NAFLD. Besides, molecular docking and dynamics simulations suggested that sanguinarine might target MICAL2 with stable binding affinity, highlighting a potential therapeutic avenue. Finally, experimental validation confirmed MICAL2 overexpression in liver tissues of NAFLD mouse models. Together, our findings support a mechanistic framework in which depression promotes NAFLD through a microbiota-mediated pathway converging on MICAL2 and macrophage dysfunction. These findings might have implications for risk stratification and early intervention of depression-induced NAFLD patients and offer novel insights into the brain-gut-liver interactions.\n\nID: 42346391\nTitle: Multi-Targeted Intervention of Eucommia ulmoides and Its Bioactive Constituents Against Metabolic Syndrome: From Molecular Mechanisms and Gut Microbiota Modulation to Clinical Translation.\nAbstract: Background/Objectives: Metabolic syndrome (MetS) is a pressing global health challenge comprising obesity, hyperglycemia, hypertension, and hyperlipidemia. Conventional polypharmacy often presents long-term compliance issues and side effects. Eucommia ulmoides Oliv., a traditional medicinal and edible plant rich in iridoids, lignans, flavonoids, and polysaccharides, has emerged as a promising natural intervention. This review aims to systematically summarize the bioavailability and multifaceted pharmacological mechanisms of E. ulmoides and its bioactive components in alleviating MetS. Methods: We comprehensively reviewed the recent in vitro and in vivo literature to map the functional evidence, specific signaling pathways, and gut microbiota-host interactions associated with E. ulmoides extracts and its key phytochemicals (e.g., asperuloside) against various metabolic dysfunctions. Results: Current evidence indicates that E. ulmoides operates through a \"multi-component, multi-target, and multi-pathway\" paradigm. For hyperlipidemia and obesity, it activates hepatic lipid metabolism (PPARα/CPT1A, FXR/CYP7A1) and mitigates oxidative stress (Nrf2/ARE). Furthermore, it dose-dependently reshapes the gut microbiota by enriching beneficial bacteria like Akkermansia and increasing butyrate production, exerting profound gut-liver axis regulation. It also ameliorates hypertension by activating the ACE2-Ang-(1-7)-Mas axis, improves insulin resistance via the AMPK/PI3K/Akt cascade, and manages hyperuricemia by modulating XOD and renal transporters. Notably, the low oral bioavailability of its glycosides highlights the crucial role of gut microbial hydrolysis in its efficacy. Conclusions: E. ulmoides holds substantial therapeutic potential as a multi-target natural supplement for MetS. However, future translational applications necessitate large-scale randomized clinical trials, multi-omics studies to further clarify host-microbiome interactions, and the development of standardized formulations to ensure clinical efficacy.\n\nID: 42344908\nTitle: Polysaccharides-gut microbiota interaction: mechanisms regulating the hepatocellular carcinoma immune microenvironment.\nAbstract: Hepatocellular carcinoma (HCC) has a poor prognosis, and the clinical responses to immune checkpoint inhibitors (ICIs) remain limited. Increasing evidence suggests that gut microbiota dysbiosis plays an important role in HCC progression through the gut-liver axis. This review summarizes the mechanisms by which polysaccharide-gut microbiota interactions reshape the immunosuppressive tumor microenvironment (TME) in HCC, and discusses the translational potential and challenges of this emerging therapeutic axis. Specifically, gut microbiota dysbiosis promotes chronic hepatic inflammation and immunosuppression through metabolites such as lipopolysaccharide, short-chain fatty acids, and bile acids. As biocompatible prebiotics, natural polysaccharides can selectively enrich beneficial gut bacteria, including Bacteroides and Akkermansia, promote the production of immunoregulatory metabolites, and regulate key signaling pathways such as TLR/NF-κB, bile acid-FXR, and PD-1/PD-L1. Nanopolysaccharides designed to improve tumor-targeting efficiency are also being explored in preclinical studies for HCC. Despite the therapeutic potential of the gut microbiota-polysaccharide-liver TME axis, several challenges remain, including polysaccharide structural heterogeneity, unclear microbiota-immune causal relationships, and undefined safe dose windows. Overall, this review provides an integrated overview of polysaccharide-based modulation of the HCC immune microenvironment and may offer insights for the development of more precise therapeutic strategies according to HCC etiological heterogeneity.\n\nID: 42339503\nTitle: The correlation between periodontitis and fatty liver and the improvement of NAFLD by periodontal treatment.\nAbstract: Emerging evidence highlights a pathophysiological interplay between periodontitis and non-alcoholic fatty liver disease yet the mechanistic underpinnings and therapeutic implications remain contentious. This review systematically elucidates molecular crosstalk through the \"oral-gut-liver axis\" and \"oral-liver axis\". A comprehensive literature review was conducted using PubMed, Scopus and Web of Science, employing keywords related to periodontal disease and non-alcoholic fatty liver disease. Analysis of 16 original studies revealed that periodontitis and its associated pathogens promote the progression of non-alcoholic fatty liver disease through multiple pathways: (1) activation of hepatic inflammatory responses (elevated IL-6, IL-17, and TNF-α levels), (2) exacerbation of metabolic dysregulation (increased HOMA-IR, ALT, and AST), and (3) disruption of the oral-gut-liver axis. Notably, non-surgical periodontal therapy demonstrated therapeutic potential by simultaneously improving periodontal health and attenuating non-alcoholic fatty liver disease progression through reduction of hepatic pro-inflammatory cytokines and fibrogenic mediators. Periodontitis may exacerbate systemic inflammation via the oral-liver and oral-gut-liver axes, inducing insulin resistance and promoting non-alcoholic fatty liver disease. Non-surgical periodontal therapy can improve non-alcoholic fatty liver disease, but methodological heterogeneity in current studies necessitates further prospective research to clarify their relationship.\n\nID: 42318107\nTitle: Effect of Oral and Gut Microbiota, Dietary Intake, and Genetic Polymorphisms on Older Adults with Metabolic Dysfunction Associated Fatty Liver Disease.\nAbstract: This study aimed to investigate the factors involved in the development and progression of metabolic dysfunction-associated fatty liver disease (MASLD) in older adults from various aspects. Among general residents aged ≥60 years who participated in a health checkup project, 124 individuals in a normal group and 77 in an MASLD group were targeted in this study. Differences in nutrient intake, MASLD-related single nucleotide polymorphisms (SNPs), and oral and gut microbiota between the normal and MASLD groups were investigated. Furthermore, multivariate analysis was conducted to determine which cardiometabolic criteria were associated with the identified variables. The MASLD group had increased oral Veillonella and Megasphaera and decreased gut Blautia. Oral Veillonella and Magasphaera were positively associated with body mass index (BMI), waist circumference, and systolic blood pressure. Gut Blautia negatively correlated with BMI, waist circumference, fasting blood sugar, HbA1c, triglycerides, and positively correlated with high-density lipoprotein cholesterol. However, no association was observed between nutritional intake and SNPs. Because oral and gut microbiota are strongly involved in MASLD in older individuals, improving oral hygiene and probiotics may prevent the onset and progression of MASLD by improving the oral and gut environment.\n\nID: 42311944\nTitle: Dendrobium officinale polysaccharide ameliorates high-fat diet-induced hepatic lipid metabolic disorder via the SIRT6/PGC-1α signaling axis.\nAbstract: This study aims to explore the potential therapeutic effect of Dendrobium officinale polysaccharide (DOP) on non-alcoholic fatty liver disease (NAFLD) induced by high-fat diet (HFD), and to elucidate the underlying mechanism involving the SIRT6/PGC-1α signaling axis and the regulation of the gut microbiota. We extracted and characterized DOP. We established a rat model of NAFLD induced by HFD and evaluated the efficacy of DOP by integrating multi-omics techniques (transcriptomics, metabolomics) and 16S rRNA sequencing. To verify the specific role of SIRT6, we introduced the SIRT6 inhibitor OSS_128167 in the primary hepatocyte model induced by oleic acid/palmitic acid (OA/PA). DOP significantly alleviated liver steatosis, oxidative stress, and lipid metabolism disorders induced by HFD. Multi-omics analysis indicated that DOP regulated liver glycerophospholipid metabolism and restored intestinal microbiota homeostasis, significantly increasing the abundance of beneficial bacteria such as Lactobacillus. Mechanistically, DOP activated the liver SIRT6/PGC-1α signaling axis, thereby enhancing antioxidant defense and inhibiting lipogenesis. Crucially, in vitro experiments confirmed that the SIRT6 inhibitor OSS_128167 eliminated the protective effect of DOP on lipid accumulation, confirming that the effect of DOP depends on SIRT6. DOP improves NAFLD through dual mechanisms of regulating the gut-liver axis homeostasis and directly activating the liver SIRT6/PGC-1α signaling pathway. The results of this study provide a theoretical basis for developing DOP as a drug for the treatment of NAFLD.\n\nID: 42300918\nTitle: The hawthorn (Crataegus pinnatifida) procyanidin extract attenuates nonalcoholic fatty liver disease in mice via remodeling the bile acid profile driven by gut microbiota and regulating the FXR pathway.\nAbstract: Hawthorn procyanidin extract (HPC) is one of natural plant-derived polyphenols with lipid-lowering and liver-protective properties, while its therapeutic mechanisms against nonalcoholic fatty liver disease (NAFLD) require further clarification. A high-fat diet (HFD)-induced NAFLD mouse model and oleic acid (OA)-induced HepG2 cells were utilized to conduct this study. We first found that HPC intervention ameliorated lipid accumulation in HepG2 cells, which was confirmed to depend on FXR signaling using an FXR inhibitior. In addition, HPC significantly relieved NAFLD in vivo by lowering the levels of TC, TG, and LDL-C and preventing the excessive accumulation of lipid droplets and hepatic steatosis. Besides, HPC intervention restored BA homeostasis (in the liver and gut) by markedly altering the profiles of primary versus secondary and conjugated versus unconjugated BAs (ωMCA, TαMCA, TβMCA, and DCA), which was related to the restoration of the HFD-induced dysbiosis. Mechanistically, HPC downregulated the expression of lipid synthesis protein SREBP1 by activating the hepatic FXR and CYP7A1 expressions, attributed to the controlling of the enterohepatic circulation mediated by the FXR-FGF15 pathway. Taken together, these findings substantiate that HPC exerts its ameliorative effect on NAFLD by modulating BA metabolism in NAFLD mice.\n\nID: 42280311\nTitle: Insulin-like Growth Factor 1 Ameliorates Intestinal Barrier Dysfunction in MASLD via IGF-1R/PI3K/AKT Signaling.\nAbstract: Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) represents a globally prevalent hepatic disorder, characterized by hepatic lipid accumulation and extrahepatic complications, notably intestinal barrier injury, which further exacerbates MASLD progression. The \"gut-liver axis\" has been identified as a critical contributor to MASLD development, with insulin-like growth factor 1 (IGF-1) serving as a pivotal coupling factor of this axis. However, the specific role and molecular mechanism by which IGF-1 modulates intestinal barrier function in the context of MASLD remains unclear. Methods: This study analyzed the correlations between the GH/IGF-1 axis and intestinal barrier function in MASLD rats, and explored the effects of IGF-1 intervention both in vivo and in vitro. Results: Our results showed that MASLD rats exhibited intestinal barrier impairment, characterized by elevated serum Diamine oxidase (DAO) and D-Lactate (D-LAC) levels, villus damage, and downregulation of tight junction proteins and Mucin (MUC2). These changes were accompanied by suppression of the GH/IGF-1 axis. Correlation analysis uncovered a negative association between IGF-1 levels and markers of barrier dysfunction. IGF-1 intervention effectively repaired the intestinal barrier structure of MASLD rats and significantly upregulated the expressions of IGF-1R, PI3K, and AKT. In vitro, IGF-1 treatment improved transepithelial electrical resistance (TEER), enhanced barrier-related gene expression, promoted cell proliferation, and inhibited apoptosis. Conclusions: These findings suggested that GH/IGF-1 axis suppression, intestinal barrier dysfunction, and IGF-1R/PI3K/AKT signaling were interconnected within the gut-liver axis in MASLD. IGF-1 may contribute to barrier regulation through associated signaling changes, highlighting the GH/IGF-1 axis as a potential complementary target.\n\nID: 42280144\nTitle: Natural Bioactive Compounds Targeting Gut Barrier Integrity and Metabolic Endotoxemia in Cardiometabolic Disease: Mechanistic Insights and Translational Perspectives.\nAbstract: Cardiometabolic diseases are increasingly recognized as disorders of chronic low-grade systemic inflammation and gut barrier dysfunction that mutually reinforce one another. Each condition amplifies the other through progressive injury to the intestinal epithelium. Compromise of the mucus layer, altered tight junction dynamics, dysbiosis, and impaired epithelial restitution promote intestinal permeability and enable the translocation of lipopolysaccharide and other microbial products into the circulation, thereby inducing metabolic endotoxemia. This gut derived inflammatory signal activates Toll like receptor 4, nuclear factor kappa B, and inflammasome associated pathways, linking barrier dysfunction to insulin resistance, hepatic steatosis, adipose tissue inflammation, endothelial activation, and vascular injury. Here, we examine the gut barrier as an immunometabolic interface and synthesize current evidence connecting its disruption to endotoxin driven cardiometabolic pathology. We further evaluate selected natural bioactive compounds, including curcumin, resveratrol, quercetin, epigallocatechin gallate, berberine, anthocyanins, omega 3 polyunsaturated fatty acids, and dietary polysaccharides, as gut targeted interventions capable of reinforcing junctional integrity, restoring mucus and microbial homeostasis, lowering endotoxin burden, and attenuating inflammatory signaling. Finally, we highlight the principal translational barriers that currently limit clinical implementation, including pharmacokinetic variability, microbiota dependent biotransformation, source standardization, and the lack of robust, standardized biomarkers of barrier restoration and metabolic endotoxemia.\n\nID: 42277386\nTitle: Modulating the Gut-Liver Axis: Anti-Inflammatory Mechanisms of Probiotics and Prebiotics in MASLD.\nAbstract: Non-alcoholic fatty liver disease (NAFLD), recently reclassified as metabolic dysfunction-associated steatotic liver disease (MASLD), is a prevalent metabolic disorder with significant inflammatory underpinnings. Emerging evidence underscores the gut-liver axis as a pivotal pathway in MASLD pathogenesis through which dysbiosis drives cytokine-mediated inflammation, fibrosis, and disease progression. This review synthesizes preclinical and clinical findings on how probiotics and prebiotics modulate key inflammatory cytokines-including TNF-α, IL-6, IL-1β, IL-10, IL-17, and TGF-β-to ameliorate MASLD. The literature demonstrates that these interventions converge on the TLR4/NF-κB axis as the central mechanistic driver of cytokine dysregulation in MASLD. By restoring gut barrier integrity and reducing endotoxin (LPS) translocation, probiotics and prebiotics suppress TLR4/NF-κB activation, which secondarily inhibits the NLRP3 inflammasome (reducing IL-1β/IL-18), downregulates pro-inflammatory cytokines (TNF-α, IL-6, IL-17), and enhances anti-inflammatory signals (IL-10) through crosstalk with PPAR-α, AMPK, and Nrf2 pathways. In animal models, probiotic strains such as Bifidobacterium, Lactobacillus, and Akkermansia muciniphila consistently downregulate pro-inflammatory cytokines and enhance anti-inflammatory signals. The same is true for prebiotics, including inulin, oat β-glucan, and synbiotic formulations. However, clinical trial outcomes remain heterogeneous, influenced by strain specificity, intervention duration, and patient heterogeneity. Collectively, this review highlights the therapeutic potential of microbiota-targeted interventions to rebalance cytokine networks and proposes future directions for personalized, mechanism-driven approaches to the management of MASLD.\n\nID: 42275581\nTitle: Gut microbiota-derived indole-3-propionic acid alleviates endoplasmic reticulum stress by regulating FMO2 in MASLD.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) has become a global health challenge for which there are currently no approved drugs. Indole-3-propionic acid (IPA), as one of the primary metabolites of gut microbiota, can influence the development of liver diseases through the gut-liver axis, but how it contributes to liver diseases remains unclear. The present study was conducted to explore the possible molecular mechanisms of IPA in the development of MASLD. Metabolomic analysis compared serum and fecal metabolite profiles between MASLD and normal mice. The effects of microbial metabolite IPA on MASLD were evaluated through the utilization of a mouse model and cell models. Transcriptome data analysis was used, and further validation was conducted through flow cytometry, western blotting, RNA interference, and immunoprecipitation. Serum and fecal IPA levels in high-fat diet-fed mice were significantly decreased compared with those of normal chow diet-fed mice. IPA supplementation reduced hepatic lipid accumulation and alleviated insulin resistance, liver damage, and steatosis development in high-fat diet-fed mice, while gut microbiota dysbiosis was restored. Mechanistic analysis suggested that IPA promoted FMO2 expression, enhancing the interaction between FMO2 and protein kinase R-like endoplasmic reticulum kinase (PERK) and inhibiting the PERK/eIF2α/ATF4/CHOP signaling cascade, then mitigating endoplasmic reticulum (ER) stress, such as reducing hepatocyte apoptosis and reactive oxygen species levels, ultimately improving MASLD. IPA can promote the expression of FMO2, which binds to PERK within the ER of hepatocytes. This binding process inhibits the phosphorylation of PERK, thereby affecting PERK-mediated ER stress, and subsequently leading to a reduction in hepatocyte apoptosis and oxidation. This study puts forward the IPA/FMO2/PERK axis as a potential therapeutic target in ER stress for MASLD.\n\nID: 42274538\nTitle: Regulation Progresses of Selenium Improving Intestinal and Extra-Intestinal Tissues Health Through Regulating Gut Microbiota.\nAbstract: Selenium (Se) is an essential trace element that exerts pleiotropic effects on host physiology, yet the mechanisms by which it coordinates systemic health remain incompletely understood. Emerging evidence regards the gut microbiota as a key mediator of Se biological functions, giving rise to the Se-gut-tissue axis. This review synthesizes the current research progresses on how dietary Se may shape gut microbial composition and metabolism, and how these microbial shifts are associated with protective effects in both intestinal and extra-intestinal tissues. Se sources (particularly organic or new synthetic form) may bidirectionally interact with gut bacteria by enriching beneficial genera such as Akkermansia, Lactobacillus, and butyrate-producing Clostridia, while suppressing opportunistic pathogens. This microbial remodeling strengthens intestinal barrier integrity, enhances antioxidant and anti-inflammatory responses (e.g., via GPX, TrxR, and NF-κB suppression), and generates bioactive metabolites, notably short-chain fatty acids and secondary bile acids. Through these mechanisms, the Se-gut-microbiota axis may regulate distal organ homeostasis, including the liver (ameliorating NAFLD and acute injury), brain (counteracting neurodegeneration and modulating serotonin/GABA), muscle (improving mass and Se deposition), kidney (attenuating uremic toxin-induced ferroptosis), and reproductive organs. Despite encouraging progress, challenges remain in establishing causality, optimizing dose-response relationships, and translating findings into precision interventions.\n\nID: 42260527\nTitle: Calculus Bovis ameliorates primary sclerosing cholangitis via a dual-pronged mechanism restoring bile acid and lipid homeostasis in the gut-liver axis.\nAbstract: Primary sclerosing cholangitis (PSC) is a progressive cholestatic liver disease lacking FDA-approved therapy. Calculus Bovis (CB), a traditional medicine derived from animal gallstones, has been historically used for treating hepatobiliary diseases, but its therapeutic potential and mechanisms in PSC remain unexplored. This study aimed to investigate the efficacy of CB in an experimental PSC model and elucidate its underlying mechanisms. A PSC mouse model was induced by a 0.1% 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC) diet for 4 weeks. Mice were treated with CB (50,100, 150 mg/kg/day) or ursodeoxycholic acid (UDCA, 100 mg/kg/day). Liver injury, fibrosis, intestinal barrier integrity, bile acid (BA) profiles, and lipid levels were assessed. Hepatic and intestinal gene/protein expression related to BA and lipid metabolism was analyzed. Integrated transcriptomics, network pharmacology, and in vitro serum pharmacology were employed to elucidate the underlying mechanisms. CB administration significantly alleviated liver injury, fibrosis, and intestinal barrier damage in DDC-induced mice. It restored BA homeostasis across the gut-liver axis, normalizing aberrant BA profiles in serum and liver while increasing BA excretion in feces. CB also ameliorated dyslipidemia, reducing hepatic and serum lipid levels. Mechanistically, CB and its bioactive BA components exerted their effects through a dual-pronged mechanism: (1) activation of the SIRT1-PGC-1α axis to transcriptionally upregulate the expression of nuclear receptors FXR and PPARα in the liver and intestine, and (2) direct ligand-dependent activation of FXR and PPARα protein functions. This concerted activation enhanced the transcription of genes involved in BA detoxification, transport, and fatty acid β-oxidation. Inhibition of SIRT1 or antagonism of FXR/PPARα attenuated these protective effects in vitro. CB attenuates experimental PSC by modulating BA and lipid homeostasis via the gut-liver axis, mediated through a novel dual mechanism involving SIRT1-PGC-1α pathway activation and direct receptor agonism. These findings not only highlight CB as a promising multi-target agent for PSC treatment, but also provide novel insights into the therapeutic modulation of metabolism in the gut-liver axis.\n\nID: 42259413\nTitle: A novel pectic polysaccharide from Prunella vulgaris L. and its therapeutic potential in alleviating alcoholic liver injury by regulating lipid metabolism and inflammation.\nAbstract: Prunella vulgaris L. (XiakuCao) is a traditional edible Chinese medicinal herb widely used for its purging properties. While its polysaccharides are known for diverse bioactivities, their potential in treating liver diseases remains closely linked to their specific structural features. Most reported polysaccharides from Prunella vulgaris L. have been complex heteropolysaccharides isolated by hot water. In this study, a new homogeneous polysaccharide, designated AO3-1, was isolated for the first time from Prunella vulgaris L. by ammonium oxalate solution after water treatment. Structural analysis revealed that AO3-1 is mainly composed of α-D-1, 4-GalpA, consistent with a typical pectic polysaccharide. Pharmacological evaluations demonstrated that AO3-1 has significant therapeutic effects in alleviating alcoholic liver injury (ALD), as indicated by the reduction of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, and the mitigation of hepatic steatosis (TG, TC, LDL-C and HDL-C). Notably, AO3-1 treatment suppressed systemic inflammation (IL-6, IL-1β and TNF-α) and effectively modulated intestinal microecology, suggesting a protective role mediated by the gut-liver axis. These findings provide the first evidence of a unique pectic polysaccharide from Prunella vulgaris L. with potent anti-ALD activity. Our study highlights the potential of AO3-1 as a novel functional food ingredient or therapeutic agent for managing alcoholic liver injury, offering a new strategy for the valorization of herbal processing by-products.\n\nID: 42249406\nTitle: Safety and metabolic effects of HTD1801 in type 2 diabetes and MASLD: a phase Ib randomized trial.\nAbstract: HTD1801 is a novel compound composed of equal parts berberine (BBR) and ursodeoxycholic acid (UDCA). It functions as a gut-liver metabolic modulator with a unique mechanism of action that may offer therapeutic benefits for patients with type 2 diabetes mellitus (T2DM) and metabolic dysfunction-associated steatotic liver disease (MASLD). A total of 48 patients were enrolled in this study. Thirty-six treatment-naïve patients were randomized to receive HTD1801 at doses of 500 mg, 750 mg, or 1000 mg, or placebo, administered twice daily for 28 days. An additional 12 patients on stable metformin therapy were randomized (3:1) to receive either HTD1801 1000 mg or placebo. HTD1801 was generally well tolerated, with most adverse events classified as mild to moderate in severity. No serious adverse events were reported. Berberine exhibited saturation kinetics, whereas UDCA demonstrated linear pharmacokinetics. Accumulation was low to moderate (range: 0.9673 to 2.6659). Compared to placebo, HTD1801 improved glucose and lipid metabolism and reduced liver enzyme levels. A dose-dependent effect was observed, with metabolic improvements increasing with higher administered doses. In the metformin group, HTD1801 (1000 mg) resulted in greater reductions in fasting glucose (mean absolute decrease: -1.271 vs. +0.423 mmol/L), 2-h postprandial glucose (-4.167 vs. +0.290 mmol/L), LDL-C (-0.623 vs. +0.290 mmol/L), total cholesterol (-1.090 vs. +0.023 mmol/L), and GGT (-9.28 vs. -4.43). HTD1801 was safe and demonstrated potential metabolic benefits in patients with T2DM and MASLD. Further investigation is warranted.

Despite its growing global burden, no widely approved pharmacotherapy is available, highlighting the need to elucidate immunometabolic mechanisms and identify effective therapeutic targets. This review summarizes the epidemiology and clinical features of MASH and focuses on key pathogenic pathways, including insulin resistance, lipotoxicity, mitochondrial dysfunction, and gut-liver axis disturbance. Immune dysregulation mediated by Kupffer cell activation, macrophage polarization, inflammasome signaling, and cytokine networks is discussed in depth. The critical role of immunometabolic crosstalk in disease progression is emphasized. Current and emerging therapeutic targets-such as PPARs, FXR, THR-β, the GLP-1/FGF21 axis, DGAT2, and CCR2/CCR5-are systematically reviewed, together with advances in oligonucleotide therapy, cell-based interventions, and combination strategies. MASH results from the complex coupling of metabolic imbalance and immune-driven inflammation, making single-target therapy insufficient. Precision stratification based on immunometabolic networks and multi-target interventions represent promising directions for future drug development and individualized treatment.\n\nID: 42242572\nTitle: Liver-brain axis mechanism underlying central immune remodeling triggered by peripheral hepatic damage.\nAbstract: Liver dysfunction and various hepatic disorders cause neuropsychiatric abnormalities including depression, anxiety, cognitive impairment and personality changes through liver-brain axis imbalance, greatly worsening patient prognosis. The liver-brain axis acts as a bidirectional network via neural, humoral, immune and gut microbiota pathways, and its disruption dominates liver disease-related central nervous system (CNS) injury. Toxic metabolites such as bilirubin activate the transient receptor potential cation channel subfamily M member 2 (TRPM2)-spleen tyrosine kinase (SYK)-nuclear factor kappa-B (NF-κB) pathway in microglia, triggering excessive glutamatergic synapse phagocytosis in the anterior cingulate cortex (ACC) and sustained neuroinflammation with irreversible neural circuit damage. This review summarizes the pathogenesis of neuropsychiatric complications induced by liver dysfunction and liver transplantation, focusing on blood-brain barrier (BBB) disruption, systemic immune activation, neurotransmitter imbalance and resident immune cell phenotypic shifts. It clarifies four liver-brain axis regulatory pathways, highlights microglial central functions, and addresses gut-liver-brain axis crosstalk, meningeal immunity, choroid plexus barrier damage and circadian rhythm disturbance. It also concludes diagnostic biomarkers including bilirubin and fibroblast growth factor 21 (FGF21), alongside therapeutic targets covering the TRPM2-SYK-NF-κB pathway, microglial polarization and gut microbiota. This study provides a unified theoretical framework for clinical diagnosis, risk stratification and targeted treatment of liver disease-related neuropsychiatric complications, and explains CNS dysfunction mechanisms underlying metabolic dysfunction-associated steatotic liver disease (MASLD), liver cirrhosis and acute-on-chronic liver failure.\n\nID: 42242027\nTitle: Bifidobacterium longum alleviation of metabolic dysfunction-associated steatotic liver disease: A multi-omics landscape of microbiota and metabolome reconfiguration.\nAbstract: The gut microbiome-host metabolism axis plays a critical role in the pathogenesis of metabolic dysfunction-associated steatotic liver disease (MASLD). Although the probiotic Bifidobacterium longum (B. longum) shows promise in ameliorating metabolic disorders, its functional impact on the microbiome-metabolome interplay in MASLD remains elusive. Herein, we established a MASLD mouse model using a high-fat, high-fructose (HFHF) diet and conducted integrated multi-omics analyses, including liver transcriptomics, gut metagenomics, and serum metabolomics, following B. longum intervention. B. longum supplementation effectively attenuated systemic metabolic dysfunction, hepatic steatosis, and intestinal barrier impairment in MASLD. This amelioration was driven by a two-pronged functional reorganization: the restoration of intestinal integrity and a profound remodeling of the hepatic transcriptome, featuring the downregulation of crucial mediators within the CD14-TLR4-NF-κB signaling cascade, including Cd14 and Runx1. Such functional reorganization coincided with a reconfigured gut microbiota, characterized by an increased abundance of beneficial taxa (e.g., Parabacteroides distasonis, Muribaculum intestinale) and suppression of opportunistic pathobionts (e.g., Ruminococcus gnavus, Clostridioides difficile). Furthermore, these microbial shifts were intrinsically linked to a reconfigured serum metabolome, highlighted by the enrichment of protective tryptophan-derived metabolites (e.g., indole-3-propionic acid) and the reduction of detrimental ones (e.g., 17α-methyltestosterone, 7-HDoHE). Collectively, our results suggest that B. longum mitigates MASLD through modulation of the gut microbiota and host serum metabolome, supporting its potential as a probiotic candidate for the management of metabolic health.\n\nID: 42240574\nTitle: Camellia diacylglycerol oil attenuates atherosclerosis and NAFLD by modulating gut microbiota and lipid metabolism in ApoE-/- mice.\nAbstract: Camellia diacylglycerol oil (CDO), produced by enzymatic glycerolysis of camellia oil, is widely consumed as a functional food ingredient; however, its cardiovascular benefits remain insufficiently characterized. This study investigated the effects of CDO on high-fat diet (HFD)-induced atherosclerosis and non-alcoholic fatty liver disease in ApoE-/- mice, with a particular focus on alterations in gut microbiota and metabolomic profiles. Compared with the vehicle group, CDO supplementation (3 and 6 mL kg-1) reduced aortic plaque area by approximately 50% without significantly affecting body weight in the mice. CDO treatment significantly decreased serum triglycerides (TG), total cholesterol (TC) and low-density lipoprotein cholesterol, at the same time as increasing high-density lipoprotein cholesterol. Notably, CDO administered at 3 mL kg-1 demonstrated greater efficacy than camellia oil in improving TG and high-density lipoprotein cholesterol levels (P < 0.05). Furthermore, CDO supplementation significantly alleviated hepatic histopathological injury, reduced Oil Red O-positive lipid deposition and lowered hepatic TG and TC levels compared to the vehicle group. Gut microbiota analysis revealed a decreased Firmicutes/Bacteroidetes ratio and increased relative abundances of Roseburia and Faecalibaculum in CDO-treated mice. Metabolomic profiling further identified ether lipid metabolism and bile acid-related pathways as potential mediators of the metabolic improvements-induced by CDO. CDO was more effective than camellia oil in mitigating HFD-induced atherosclerosis and non-alcoholic fatty liver disease in ApoE-/- mice, most likely through coordinated modulation of the gut-liver-vascular axis. These findings support the potential of CDO as a functional food ingredient for cardiovascular risk reduction and warrant further validation in human studies. © 2026 Society of Chemical Industry.\n\nID: 42233026\nTitle: Resveratrol ameliorates intrahepatic cholestasis of pregnancy by modulating the gut-liver axis and FXR-mediated bile acid homeostasis.\nAbstract: Intrahepatic cholestasis of pregnancy (ICP) is a liver disorder with limited treatment options. This study investigated the therapeutic potential of resveratrol (RES) and its underlying mechanisms, focusing on the gut-liver axis and bile acid metabolism in an estrogen-induced ICP rat model. Pregnant rats were randomized into Sham, ICP (induced by 17β-estradiol), and ICP+RES (15, 30, 60 mg/kg) groups. Systemic and hepatic inflammation, liver function, histopathology, and intestinal barrier integrity were assessed. Hepatic bile acid profiles were analyzed by UHPLC-MS/MS, and gut microbiota was evaluated by 16S rRNA sequencing. The role of gut microbiota was further examined via fecal microbiota transplantation (FMT) in pseudogerm-free rats. Key proteins in the FXR signaling pathway were analyzed by Western blotting. RES treatment dose-dependently alleviated ICP manifestations, including reducing serum levels of total bile acids, total bilirubin, and liver enzymes (AST, ALT, ALP), while mitigating systemic and hepatic inflammation. It also restored intestinal barrier integrity and corrected gut microbiota dysbiosis. FMT from RES-treated donors recapitulated these therapeutic effects in recipient ICP rats. Furthermore, RES reversed the hepatic bile acid imbalance by reducing primary bile acids and increasing beneficial secondary bile acids. Mechanistically, RES upregulated the expression of FXR and its downstream targets, including SHP, BSEP, UGT2B4, and CYP1A1. RES effectively ameliorated ICP through multi-faceted mechanisms involving the attenuation of inflammation, restoration of gut microbiota and intestinal barrier, and correction of bile acid homeostasis via activation of the FXR signaling pathway. Our findings highlight RES as a promising multi-mechanistic therapeutic candidate for ICP.\n\nID: 42223079\nTitle: Chronic Liver Disease, Liver Damage and Liver Failure After Hypoabsorptive Bariatric Surgery: A Dose-Dependent Relationship and Multisystemic Consequences.\nAbstract: Metabolic bariatric surgery remains the most potent weapon we have against severe obesity and its metabolic consequences. Yet, its effects on the liver are far from uniform. Although restrictive and mixed procedures like sleeve gastrectomy and Roux-en-Y gastric bypass consistently improve metabolic dysfunction-associated steatotic liver disease (MASLD), hypoabsorptive operations carry a distinct and troubling risk of progressive liver injury. The available evidence, drawn predominantly from case series, registry data and retrospective analyses, suggests that this risk is not an all-or-nothing phenomenon but instead follows a conceptual gradient, one that correlates with the degree of intestinal malabsorption and, more specifically, with the extent of bile acid malabsorption. This review traces the evidence for this dose-dependent relationship from the historical disaster of the jejunoileal bypass to contemporary procedures like the biliopancreatic diversion and the single-anastomosis duodenal-ileal bypass. We explore the pathophysiological triad that drives this process-protein-energy malnutrition, bacterial overgrowth, and bile acid hepatotoxicity-supported by recent experimental evidence directly linking biliary limb length to liver injury. The review then contextualizes the discussion within associated multisystemic consequences, including de novo inflammatory bowel disease, severe metabolic bone disease, and a distinct discussion of the accelerated alcohol-associated liver disease that follows bariatric surgery. A synthesis of the available evidence supports the abandonment of a one-size-fits-all approach in favour of meticulous patient selection, precise and individualized surgical technique based on measured bowel length and a commitment to lifelong, intensive, multidisciplinary postoperative surveillance. Hypoabsorptive bariatric procedures carry a dose-dependent risk of progressive liver injury mediated by malabsorption, bacterial overgrowth and bile acid hepatotoxicity, necessitating individualized surgical planning and lifelong follow-up.\n\nID: 42221532\nTitle: Fecal microbiota transplant and its usefulness in hepatic disorders: a systematic review.\nAbstract: Fecal microbiota transplantation (FMT) is an emerging therapeutic approach aimed at restoring gut microbial balance through the transfer of stool from healthy donors. It has gained significant attention for its role in managing gut dysbiosis-associated disorders, particularly hepatic diseases. This systematic review evaluated the therapeutic efficacy and clinical potential of FMT in the management of liver-related conditions, including recurrent Clostridium difficile infection (CDI), non-alcoholic fatty liver disease, liver cirrhosis, and hepatic encephalopathy. A systematic review of existing literature was conducted to assess the clinical outcomes, mechanisms, and challenges associated with FMT in hepatic disorders. Relevant studies were identified from peer-reviewed scientific databases, focusing on clinical trials, observational studies, and experimental research investigating the role of FMT in gut dysbiosis and liver disease. Data were analyzed to evaluate efficacy, underlying mechanisms, and safety considerations. FMT demonstrated high efficacy in recurrent CDI, with cure rates exceeding 80%-90%. In hepatic disorders, FMT was associated with improved microbial diversity, enhanced gut barrier integrity, and reduced systemic inflammation, contributing to better liver function and clinical outcomes. However, variability in donor selection, potential safety risks, and regulatory limitations remain significant challenges. FMT represents a promising therapeutic strategy in hepatology, underscoring the critical role of the gut-liver axis. Advances such as synthetic microbiota and personalized microbiome-based therapies may further optimize its safety and efficacy, paving the way for innovative, microbiome-centered interventions in liver disease management.\n\nID: 42217150\nTitle: Lactobacillaceae in Acute and Chronic Liver Diseases: From Microbiota Modulation to Therapeutic Potential.\nAbstract: Liver diseases, including metabolic-associated fatty liver disease (MAFLD), alcoholic liver disease (ALD), and viral hepatitis, are highly prevalent and constitute a major global health burden. Accumulating evidence indicates that dysbiosis of the gut microbiota is closely associated with the development and progression of various liver diseases. Among microbial regulators, Lactobacillaceae, a family of probiotic lactic acid bacteria, has attracted considerable attention for its capacity to reshape the gut microbiota, strengthen mucosal barrier integrity, modulate nutrient metabolism, and regulate both innate and adaptive immune responses. A growing body of evidence has shown that members of the Lactobacillaceae family can alleviate hepatic inflammation, reduce steatosis, and modulate gut-derived metabolic pathways involving bile acids, lactate, and short-chain fatty acids. This review provides a comprehensive overview of the role of Lactobacillaceae in acute and chronic liver diseases, examines the mechanisms by which this family influences liver diseases through the gut-liver axis, and highlights future directions for microbiota-based therapeutic strategies.\n\nID: 42217069\nTitle: Therapeutic effects of chitooligosaccharide-epigallocatechin gallate conjugate on NAFLD: impact on gut-liver axis, lipid metabolism, and inflammation in rats fed a high-fat diet.\nAbstract: Non-alcoholic fatty liver disease (NAFLD) is a progressive disorder correlated with hepatic lipid homeostasis, gut dysbiosis, and inflammation. In this study, we propose a novel dietary therapy for NAFLD utilizing a conjugate of chitooligosaccharide (COS) and epigallocatechin gallate (EGCG), as the underlying mechanisms of NAFLD remain unclear. NAFLD was induced in male Wistar rats by administering a high-fat diet (HFD) for 16 weeks, followed by administration of COS-EGCG conjugate (150, 300, and 600 mg/kg) for an additional four weeks. The treatment alleviated metabolic parameters, liver steatosis, and injury. It also reduced hepatic lipid accumulation by downregulating the expression of CD36, fatty acid synthase (FASN), and sterol regulatory element-binding protein 1c (SREBP-1c), while upregulating peroxisome proliferator-activated receptor alpha (PPARα), carnitine palmitoyltransferase 1 A (CPT1A), and microsomal triglyceride transfer protein (MTTP). Regarding the gut-liver axis, the conjugate modulated gut microbiota, reduced serum lipopolysaccharide (LPS) levels, and restored the expression of intestinal tight junction proteins (zonula occludens-1; ZO-1 and occludin). It also prevented liver inflammation induced by gut-derived LPS by suppressing the Toll-like receptor 4 (TLR4)/nuclear factor kappa B (NF-κB) signaling pathway. The results suggest that the COS-EGCG conjugate exerts therapeutic effects against NAFLD by regulating hepatic lipid metabolism, modulating the gut microbiota, and attenuating gut-derived LPS-induced liver inflammation.\n\nID: 42208886\nTitle: Perfluoroalkyl and polyfluoroalkyl substances exposure and liver disease: A review.\nAbstract: Per- and polyfluoroalkyl substances (PFASs) are widely used in numerous industrial processes and consumer products and are now ubiquitously distributed in the environment, thereby creating multiple routes of human exposure. Their physicochemical properties confer high persistence, bioaccumulation potential, and toxicity, which have raised increasing concern about their long-term impacts on human health. Because of its central role in xenobiotic uptake, metabolism, transport, and excretion, the liver is considered a major target organ of PFAS toxicity. Over the past few years, a growing body of epidemiological, in vivo, and in vitro evidence has linked PFAS exposure to a broad spectrum of hepatic abnormalities, including liver injury, cholestatic liver injury and bile acid dysregulation, metabolic dysfunction-associated steatotic liver disease (MASLD), and hepatocellular carcinoma (HCC). In addition to legacy long-chain PFASs, short-chain congeners and emerging alternatives such as GenX and 6:2 Cl-PFESA have also shown considerable hepatotoxic potential. This review summarizes current evidence on the contribution of PFAS exposure to liver disease, with particular attention to human relevance and the mechanisms underlying PFAS-induced hepatotoxicity, including oxidative stress, inflammatory activation, disruption of the gut-liver axis and enterohepatic circulation, lipid metabolic reprogramming, and impairment of bile acid homeostasis. Remaining knowledge gaps and future perspectives are also highlighted to support mechanistic understanding and improve PFAS-related liver risk assessment.\n\nID: 42196377\nTitle: Integrated Network Pharmacology and Gut Microbiota Analysis Reveals the Alcoholic Extract of Anacyclus pyrethrum Root Prevents Nonalcoholic Fatty Liver Disease via the LPS/TLR4/NF-κB Pathway.\nAbstract: The global incidence of nonalcoholic fatty liver disease (NAFLD) is rising, with no approved pharmacotherapy available. Medicinal plants offer a potential preventive strategy. Anacyclus pyrethrum root exhibits anti-inflammatory and glucose-regulating properties, but its role in NAFLD prevention is unclear. This study aims to investigate the preventive effect of Anacyclus pyrethrum root ethanol extract (APE) against NAFLD and its underlying mechanisms. The chemical composition of APE was analyzed by UHPLC-HRMS. Network pharmacology predicted the potential signaling pathways underlying its protective effects against NAFLD. In a 12-week high-fat diet mice model, APE treatment led to measurements of blood glucose, lipid profiles, liver function parameters, histopathological changes in liver and colon, and gut microbiota alterations via 16S rDNA sequencing. In animal experiments, APE lowered fasting and random blood glucose, total cholesterol, triglycerides, LDL-C, AST, ALT, and serum lipopolysaccharide while increasing HDL-C, and alleviated hepatic steatosis. Network pharmacology suggested APE acts via TLR, NF-κB, and TNF pathways. In vivo, APE suppressed hepatic TLR4, MyD88, p-NF-κB p65, the p-NF-κB p65/NF-κB p65 ratio, and TNF-α/IL-6 levels. Gut microbiota analysis showed increased Akkermansiaceae and decreased Desulfovibrionaceae. APE also upregulated intestinal Occludin and ZO-1, and downregulated intestinal TNF-α and IL-6. APE prevents NAFLD progression, potentially by regulating gut microbiota, protecting the intestinal mucosal barrier, and inhibiting the LPS/TLR4/MyD88/NF-κB pathway.\n\nID: 42193472\nTitle: Metabolic Dysfunction-Associated Steatotic Liver Disease: An Update Narrative Review of the Therapeutic Potential of Combining Probiotics and Metformin.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) has replaced older exclusion-based terminology as the preferred term for steatotic liver disease associated with cardiometabolic risk factors. MASLD is now among the most common causes of chronic liver disease and may progress from simple steatosis to metabolic dysfunction-associated steatohepatitis (MASH), fibrosis, cirrhosis, and hepatocellular carcinoma. This updated rigorous narrative review synthesizes current evidence on MASLD diagnosis and management, with emphasis on the gut-liver axis and the therapeutic potential of combining probiotics with metformin. A structured narrative search was conducted in PubMed, PMC, ScienceDirect, Taylor & Francis, Cochrane Library, and Google Scholar using the keywords \"MASLD\", \"MAFLD\", \"NAFLD\", \"MASH\", \"probiotics\", \"synbiotics\", \"metformin\", and \"gut-liver axis\". The review was designed as a narrative synthesis rather than a systematic review. Current guidance supports stepwise risk stratification using serum fibrosis scores followed by elastography or advanced imaging when indicated. Ultrasonography remains accessible but has limited sensitivity for mild steatosis, is operator-dependent, and is not sufficient for comprehensive assessment of fibrosis or disease activity. Metformin is appropriate for type 2 diabetes mellitus and improves insulin resistance, but current guidelines do not recommend it as a targeted treatment for MASH because histological benefit has not been consistently demonstrated. Probiotics and synbiotics may improve aminotransferases, inflammatory markers, lipid parameters, intestinal barrier function, and gut dysbiosis; however, findings vary by strain, formulation, dose, treatment duration, population, and endpoint. The combination of probiotics and metformin is mechanistically plausible because it targets both metabolic dysfunction and intestinal dysbiosis, but human evidence remains limited. Larger, strain-specific, adequately powered trials using standardized MASLD criteria and clinically meaningful endpoints are required before routine clinical recommendations.\n\nID: 42193367\nTitle: Small Intestinal Bacterial Overgrowth in Metabolic Dysfunction-Associated Steatotic Liver Disease: Prevalence, Subtypes, and Risk Factors Across Disease Spectrum and Comorbidity Profiles.\nAbstract: Background: Small intestinal bacterial overgrowth (SIBO) has been implicated in the pathogenesis of MASLD; however, large-scale clinical data characterizing prevalence patterns, phenotypic subtypes, and disease-specific associations remain limited. Methods: This cross-sectional study enrolled 2549 MASLD patients with gastrointestinal symptoms undergoing lactulose methane-hydrogen breath testing and transient elastography. Univariate and multivariable analysis identified independent risk factors for SIBO. We also explore the distribution of SIBO subtypes and their associations with comorbidity profiles across the MASLD spectrum. Results: The overall prevalence of SIBO was 66.3%, escalating from 65.9% in MASL to 72.8% in at-risk MASH and 78.9% in cirrhosis, alongside a notable enrichment of the intestinal methanogen overgrowth (IMO) phenotype. Multivariable analysis identified advanced fibrosis (stage F4; OR = 1.75, 95% CI: 1.03-2.96), gastroesophageal reflux disease (GERD; OR = 1.66, 95% CI: 1.22-2.28), and coronary artery disease (CAD; OR = 1.80, 95% CI: 1.06-3.06) as independent predictors of SIBO. Additionally, elevated ALT (OR = 1.01, 95% CI: 1.01-1.13) showed a modest association with SIBO. Subtype analysis revealed that IMO was associated with GERD, alcohol consumption, CAD, and obesity, while a history of cholecystectomy and elevated triglycerides were linked to early-phase hydrogen peaks. Conclusions: SIBO is highly prevalent among patients with MASLD, with its prevalence and phenotypic subtype distribution being closely associated with disease severity. The identification of fibrosis-specific risk factors and subtype-clinical associations suggest consideration of SIBO assessment in advanced MASLD, particularly in patients with cardiometabolic or gastrointestinal comorbidities.\n\nID: 42188294\nTitle: Structural Characterization of an α-D-glucan from Bellamya purificata and Its Protective Effects on Non-Alcoholic Fatty Liver Disease in Zebrafish.\nAbstract: Non-alcoholic fatty liver disease (NAFLD) is a primary metabolic disorder that threatens adolescent health globally, with no effective therapeutic agents currently available. Bellamya purificata is a traditional Chinese medicine categorized as \"medicinal food\", and polysaccharides are among its active components. However, its physicochemical structure remains poorly characterized, and no study has evaluated its effects on NAFLD. In this study, a homogeneous neutral polysaccharide, α-D-glucan (Mw = 6412.704 kDa), was isolated from B. purificata. The structure of the polysaccharide was characterized using monosaccharide composition analysis, methylation analysis, NMR spectroscopy, and scanning electron microscopy. The backbone structure of the polysaccharide comprises →4)-α-D-Glcp-(1→ and →4,6)-α-D-Glcp-(1→, with side chains of α-D-Glcp-(1→ attached to the O-6 position of the 1→4,6)-α-D-Glcp-(1→ sugar residues. Additionally, QSPS-1D effectively reduced weight gain, hepatic lipid accumulation (TC and TG), and inflammatory responses (tnf-α and il-1β) in NAFLD zebrafish. Moreover, QSPS-1D alleviated dysbiosis by inhibiting harmful bacteria (e.g., Stenotrophomonas, Agrobacterium, and Chryseobacterium) and promoting beneficial microbiota (e.g., Rothia), which restored the Firmicutes-to-Bacteroidetes ratio. In parallel, it enhanced the expression of tight junction proteins (zo-1 and claudin-1), leading to the repair of the intestinal mucosal barrier. These findings suggest that B. purificata polysaccharides may be a potential functional food for early NAFLD intervention, with effects potentially associated with the modulation of the gut microbiota.\n\nID: 42188051\nTitle: TCM-Derived Natural Compounds Targeting the Gut Microbiota in Metabolic Dysfunction-Associated Steatotic Liver Disease: Gut-Liver Axis Mechanisms, Safety Considerations, and Translational Challenges.\nAbstract: The occurrence and development of metabolic dysfunction-associated steatotic liver disease (MASLD) are closely related to intestinal flora imbalance, intestinal barrier damage, and gut-liver axis dysfunction. Due to their multi-target regulatory effects and advantages in intestinal microecological intervention, Chinese herbal monomers have shown promising application prospects in the prevention and treatment of MASLD. However, basic research on their toxicity still lags behind, and issues related to safety and clinical translation urgently need attention. This article systematically reviews the research progress on how flavonoids, triterpenoids, alkaloids, and polysaccharides improve hepatic steatosis, inflammatory responses, and metabolic disorders from a toxicological perspective by reshaping the intestinal microbiota, repairing the intestinal mucosal barrier, regulating short-chain fatty acid and bile acid metabolism, and synergistically acting on signaling pathways such as TLR4/NF-kB, FXR, TGR5, SIRT1, and the NLRP3 inflammasome. Furthermore, by combining methods such as 16S rRNA sequencing, metagenomics, metabolomics, and multi-omics integration, the article analyzes their application value and limitations in toxicological mechanism research, and discusses the translational bottlenecks faced by Chinese herbal monomers in pharmacokinetics, bioavailability, quality standardization, targeted delivery, and toxicological safety. Existing evidence indicates that Chinese herbal monomers have a three-in-one intervention advantage of microecological remodeling-metabolic regulation-inflammation inhibition, but their long-term medication safety, toxic target organs, dose-effect/toxicity relationships, and potential drug interactions still need further clarification. This article aims to provide a systematic reference for the safety evaluation and clinical translational research of Chinese herbal monomers in the prevention and treatment of MASLD.\n\nID: 42183858\nTitle: Metformin-phytochemical combination therapy in metabolic dysfunction-associated steatotic liver disease: mechanistic insights and therapeutic potential.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a multifactorial metabolic disorder characterized by excessive hepatic lipid accumulation, insulin resistance, oxidative stress, and chronic inflammation. Its pathogenesis spans interconnected metabolic, inflammatory, and fibrotic pathways, limiting the efficacy of single-target therapeutic approaches. Metformin (MET), a first-line antidiabetic agent, improves hepatic lipid metabolism primarily through AMPK activation and enhanced fatty acid oxidation; however, its therapeutic impact on inflammatory and redox pathways remains limited, and its use is frequently associated with gastrointestinal adverse effects. In this context, phytochemicals-diverse plant-derived bioactive compounds with pleiotropic metabolic and antioxidant properties-have emerged as promising adjuncts to MET to achieve broader pathway coverage. For the first time, this comprehensive review evaluates preclinical in vivo evidence on metformin-phytochemical combination therapy in in vivo models of MASLD, with a specific focus on its mechanistic and therapeutic advantages over monotherapy. A comprehensive literature search was conducted using PubMed, Scopus, Web of Science, and Google Scholar. Only original preclinical in vivo studies evaluating the combination of metformin with an isolated phytochemical in animal models of MASLD were included. Data were extracted on compound identity, dosing regimens, experimental models, and metabolic, inflammatory, and signaling outcomes. Across eligible studies, metformin-phytochemical combinations consistently demonstrated superior efficacy compared with monotherapy in reducing hepatic steatosis, oxidative stress, and inflammatory mediators. Combinations involving berberine, chlorogenic acid, genistein, malvidin, morin, silymarin, and p-coumaric acid were associated with improved energy metabolism and fatty acid β-oxidation, alongside suppression of lipogenesis and fibrotic signaling. Additional benefits reported across studies included modulation of adipose tissue metabolism, enhancement of autophagy-related pathways, and favorable effects on gut-liver axis signaling, depending on the phytochemical class and experimental context. Overall, the preclinical in vivo evidence indicates that metformin-phytochemical cotherapy provides a multipathway modulatory framework integrating metabolic, anti-inflammatory, and antifibrotic effects. These findings support the translational potential of this combination strategy; however, well-designed clinical studies are required to assess pharmacokinetic compatibility, optimize dosing ratios, and determine its relevance in human MASLD.\n\nID: 42183058\nTitle: Gut-engineered Bacillus subtilis-mediated BAMBI delivery for the treatment of thioacetamide-induced liver fibrosis through mechanotransduction inhibition.\nAbstract: Liver fibrosis, driven by chronic injury and excessive extracellular matrix (ECM) deposition, lacks effective clinical therapies. This study pioneers a strategy employing genetically engineered Bacillus subtilis (strain Bs-BAMBI-8) to constitutively secrete bone morphogenetic protein and activin membrane-bound inhibitor (BAMBI), which is subsequently delivered to the liver via the gut-liver axis to therapeutically antagonize liver fibrosis. Methodologically, liver fibrosis was induced in mice via 6-week intraperitoneal injections of thioacetamide (TAA), followed by a 19-week daily oral gavage of live Bs-BAMBI-8 (109 CFU). This longitudinal intervention achieved sustained intestinal colonization (>105 CFU) and BAMBI translocation via the gut-liver axis. This intervention significantly reduced hepatic fibrosis, evidenced by decreased NAFLD Activity Score from six to four and regression of fibrosis stage from S3 to S2. Mechanistically, BAMBI acted as a decoy receptor for transforming growth factor-beta (TGF-β), inhibiting TGF-β signaling and downregulating fibrotic markers (α-smooth muscle actin, collagen I, phosphorylated focal adhesion kinase). This suppression disrupted ECM-mediated mechanotransduction pathways, attenuating hepatic stellate cell activation. Concomitantly, serum markers (alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, total bilirubin) recovered, while albumin synthesis and platelet count recovered. Crucially, this engineered microbiome-based approach integrates synthetic biology with mechanobiology to simultaneously target biochemical signaling and mechanical transduction. It establishes a potentially translatable paradigm for chronic liver disease therapy.\n\nID: 42182451\nTitle: Targeting Microbial Bile Salt Hydrolase Reprograms Bile Acid Metabolism and Ameliorates Metabolic Dysfunction-Associated Steatohepatitis in Mice.\nAbstract: Microbial bile salt hydrolase (BSH) plays a central role in shaping bile acid composition and gut-liver metabolic signaling, yet its therapeutic potential in metabolic dysfunction-associated steatohepatitis (MASH) remains incompletely defined. Here, we evaluated the efficacy of the non-absorbable BSH inhibitor GR-7 in a diet induced mouse model of steatohepatitis using early and late intervention strategies with different dosing regimens. GR-7 reduced food intake and exerted stage- and dose-dependent therapeutic effects, with early intervention robustly suppressing hepatic fibrosis even at low dose, whereas late-stage administration of high-dose GR-7 markedly reduced hepatic steatosis and inflammation, as evidenced by decreased liver weight, hepatic triglyceride and cholesterol levels, and plasma ALT. Although late intervention did not result in statistically significant histological reversal of fibrosis, a trend toward improvement was observed, together with suppression of fibrogenic gene expression, suggesting that prolonged treatment may further enhance antifibrotic efficacy. Mechanistically, GR-7 effectively inhibited microbial BSH activity in vivo, leading to reduced cecal unconjugated primary and secondary bile acids-including deoxycholic acid and lithocholic acid, which was associated with improved gut barrier integrity and reduced hepatic inflammation. In parallel, BSH inhibition reprogrammed hepatic bile acid metabolism toward activation of the alternative CYP27A1-mediated synthesis pathway, accompanied by reduced food intake, thereby contributing to improved hepatic lipid accumulation. Furthermore, late-stage high-dose treatment selectively remodeled the hepatic immune landscape rather than fully restoring homeostasis, highlighting immune recalibration as a key component of therapeutic response. Together, these findings identify microbial BSH inhibition as a promising microbiome-targeted therapeutic strategy for MASH.\n\nID: 42182019\nTitle: Restoring circadian disrupted gut microbial metabolite rhythms with phytochemicals: a new avenue against metabolic disease.\nAbstract: The global epidemic of metabolic diseases-encompassing obesity, type 2 diabetes mellitus (T2DM), non-alcoholic fatty liver disease (NAFLD), and cardiovascular disease-represents a defining public health challenge of our era. The traditional model of simple caloric excess vs. expenditure has proven insufficient, giving way to a paradigm that acknowledges complex interactions between genetics, environment, and lifestyle, mediated by intricate physiological systems. Among these, the host circadian timing system and the gut microbiome have ascended as pivotal, deeply intertwined regulators of metabolic homeostasis. The gut microbiome, far from a static collection of microbes, constitutes a dynamic and metabolically active community whose composition and, critically, its functional output exhibit profound and predictable diurnal oscillations. The host's circadian clocks regulate microbial rhythms primarily by controlling the daily cycle of feeding and fasting. Modern life induces circadian disruption (CD) through ubiquitous exposure to artificial light at night, shift work, social jet lag, and erratic eating patterns. It perturbs the rhythmic dynamics of the gut ecosystem, leading to a fundamental dysregulation in the temporal production of key microbial metabolites. These metabolites, including short-chain fatty acids, secondary bile acids (BAs), indoles and other tryptophan derivatives, function as indispensable chemical messengers that coordinate peripheral metabolism, immune responses, and energy homeostasis in a precise, time-of-day-dependent manner. Their desynchronization-manifesting as mistimed, deficient, or incessant signaling-directly instigates the core pathologies of metabolic disease: insulin resistance, adipocyte dysfunction, hepatic lipid accumulation, and chronic low-grade inflammation. This review synthesizes current evidence to delineate the multilevel mechanisms through which CD drives the dysregulation of gut microbiome metabolite rhythms and establishes the causal pathways linking this dysrhythmia to metabolic pathogenesis. Furthermore, we undertake a critical evaluation of the promising therapeutic potential of dietary phytochemicals-a diverse class encompassing polyphenols, glucosinolates, and prebiotic fibers-to act as chrono-therapeutic agents. Through their multifaceted capacity to remodel microbial ecology, calibrate microbial enzymatic output, and reinforce host circadian-metabolic coupling, phytochemicals present a novel, physiologically aligned, and sustainable dietary strategy for the prevention and management of metabolic disorders. We conclude by outlining key translational challenges and propose future research directions essential for harnessing the potential of the \"clock-microbiome-metabolite\" axis within the framework of precision nutrition and medicine.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson’s complementary-but-disjoint (A-B-C) model.

Conventional polypharmacy often presents long-term compliance issues and side effects. Eucommia ulmoides Oliv., a traditional medicinal and edible plant rich in iridoids, lignans, flavonoids, and polysaccharides, has emerged as a promising natural intervention. This review aims to systematically summarize the bioavailability and multifaceted pharmacological mechanisms of E. ulmoides and its bioactive components in alleviating MetS. Methods: We comprehensively reviewed the recent in vitro and in vivo literature to map the functional evidence, specific signaling pathways, and gut microbiota-host interactions associated with E. ulmoides extracts and its key phytochemicals (e.g., asperuloside) against various metabolic dysfunctions. Results: Current evidence indicates that E. ulmoides operates through a \"multi-component, multi-target, and multi-pathway\" paradigm. For hyperlipidemia and obesity, it activates hepatic lipid metabolism (PPARα/CPT1A, FXR/CYP7A1) and mitigates oxidative stress (Nrf2/ARE). Furthermore, it dose-dependently reshapes the gut microbiota by enriching beneficial bacteria like Akkermansia and increasing butyrate production, exerting profound gut-liver axis regulation. It also ameliorates hypertension by activating the ACE2-Ang-(1-7)-Mas axis, improves insulin resistance via the AMPK/PI3K/Akt cascade, and manages hyperuricemia by modulating XOD and renal transporters. Notably, the low oral bioavailability of its glycosides highlights the crucial role of gut microbial hydrolysis in its efficacy. Conclusions: E. ulmoides holds substantial therapeutic potential as a multi-target natural supplement for MetS. However, future translational applications necessitate large-scale randomized clinical trials, multi-omics studies to further clarify host-microbiome interactions, and the development of standardized formulations to ensure clinical efficacy.\n  --- END ACTUAL ABSTRACT FOR 42346391 ---\n\n\n✅ PASSED (DO NOT CHANGE THESE):\n- \"GRE administration effectively prevented the decrease in the gut microbial richness and diversity caused by WD\" (Source: 42436161)\n- \"MPL diet markedly reshaped the gut microbiota composition disrupted by HFHS feeding.\" (Source: 42435155)\n- \"C. massiliensis also suppressed systemic and colonic inflammation, accompanied by upregulation of metabolic homeostasis-related genes (ppara, pparg, ucp2).\" (Source: 42434935)\n- \"Herbal medicines ameliorate metabolic diseases through multi-target gut microbiota modulation, involving SCFA production, bile acid metabolism, and inflammatory pathway attenuation.\" (Source: 42428317)\n- \"PVP and RA significantly alleviated hepatic lipid accumulation in HepG2 cells, inhibited intestinal cholesterol absorption, and promoted cholesterol efflux in Caco-2 monolayers.\" (Source: 42428305)\n- \"LCA supplementation recapitulates these benefits through gut microbiota-dependent conversion to 3-oxo-LCA.\" (Source: 42425970)\n- \"Moreover, the YJP improved intestinal barrier integrity and upregulated intestinal HIF-1α and occludin expression, reflecting a therapeutic mechanism involving coordinated regulation of the gut-liver axis.\" (Source: 42423000)\n- \"Unexpectedly, treatment of acid-suppressed mice with non-absorbable antibiotics designed to suppress Gram-positive bacteria worsened ethanol-induced steatohepatitis\" (Source: 42421214)\n- \"cis-Gnetin H remodeled the gut microbiota by enriching beneficial genera and reducing pathogenic Staphylococcus.\" (Source: 42419122)\n- \"Participants with metabolic dysfunction-associated steatotic liver disease at baseline as well as those achieving ≥5% weight loss had greater reductions in hepatic fat fraction than those who did not\" (Source: 42413768)\n- \"Sinensetin administration ameliorated hepatic steatosis, inflammation, and restored intestinal integrity in HFD-fed mice.\" (Source: 42421922)\n- \"IEC-specific deletion of neutral ceramidase decreases 2-HHA levels, restores AhR signalling, enhances fucosylation and protects against MASH.\" (Source: 42403915)\n- \"DYMJ treatment restored microbial balance closer to normal-diet (ND) conditions, particularly by elevating nicotinic acid adenine dinucleotide and enriching Bacteroidetes phylum species associated with metabolic health.\" (Source: 42395745)\n- \"RGE significantly reduced hepatic steatosis in comparison to the model group.

Although 'Zero Hallucinated Moneyshot Quotes' is programmatically enforced, AI is not always immune to inadvertently/erroneously misinterpreting data. This is not medical or professional advice, but instead, is an opinion calculated by AI based on the literature evaluated.\n\n### [CLAIM EVALUATED AND ANSWER TO USER]\nCan fatty liver disease be treated in order to restore gut health?\n\n### [ABSTRACT & REWRITTEN CLAIM]\nEvidence from recent preclinical and mechanistic studies indicates that therapeutic interventions targeting Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) frequently exert bidirectional benefits on the gut-liver axis. By employing pharmacological, nutritional, or probiotic strategies that attenuate hepatic steatosis, inflammation, and fibrogenesis, researchers have observed a concomitant restoration of gut microbial ecology, intestinal barrier integrity, and metabolic homeostasis, suggesting that the treatment of fatty liver disease is a viable strategy for restoring gut health.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe paradigm of the gut-liver axis suggests that the liver and the gut are functionally interconnected; therefore, interventions targeting one often propagate restorative effects to the other. Evidence demonstrates that the administration of bioactive compounds, probiotics, and targeted therapeutics can mitigate hepatic damage while simultaneously remediating gut dysbiosis. For instance, the modulation of gut-derived metabolites—such as bile acids and short-chain fatty acids—serves as a primary mechanism by which liver-targeted treatments improve intestinal health. Many interventions, such as the use of natural products or pharmacological agents, have been shown to ameliorate hepatic steatosis and inflammatory responses while restoring mucosal integrity, characterized by the upregulation of tight junction proteins. These findings underscore that the liver's metabolic state is intrinsically coupled to the gut microenvironment, and successful management of liver pathology often functions as an indirect, yet effective, therapy for gastrointestinal dysfunction.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   The \"clock-microbiome-metabolite\" axis suggests that chronotherapeutic strategies, such as time-restricted eating, may influence liver health and gut microbial rhythmicity.\n*   Certain antibiotics, while intended to reduce pathogenic bacteria, may paradoxically aggravate liver injury in specific metabolic contexts by inducing microbial shifts.\n*   Gut commensal *Bacteroides fragilis* produces pantothenic acid, which is essential for host intestinal barrier function and metabolic health.\n*   A \"dual-pronged\" mechanism in traditional medicines, such as *Calculus Bovis*, suggests that simultaneous regulation of lipid metabolism and bile acid composition is necessary for holistic gut-liver axis restoration.\n*   The use of engineered bacteria (e.g., *Bacillus subtilis* secreting BAMBI) reveals the potential for the gut-liver axis to serve as a drug delivery pathway for hepatic therapeutics.\n*   Maternal cold exposure programs offspring metabolic health through a bile acid-microbiota-Th17 axis, demonstrating the long-term impact of environmental factors on the gut-liver connection.\n*   Dietary polyphenol extracts, such as those from walnut green husks, improve intestinal morphology and microbial composition in animal models of hepatic fat accumulation.\n*   The gut microbiota-derived extracellular vesicles represent a recently recognized mechanism for cross-kingdom communication regulating hepatic metabolic and immune homeostasis.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Lycium barbarum seed polyphenols (LBSPs), a byproduct of Lycium barbarum processing, have shown antioxidant and anti-inflammatory bioactivities, but potential anti-T2DM effects remain unclear. To evaluate the preventive effects of LBSPs against T2DM and the associated gut microbiota mechanisms. The effects of LBSPs on fasting blood glucose, insulin sensitivity, liver lipid accumulation, intestinal barrier, gut microbiota composition, and microbial metabolites were investigated in db/db mice. LBSPs significantly reduced fasting blood glucose, improved insulin sensitivity, and alleviated dyslipidemia and hepatic steatosis in db/db mice. Furthermore, LBSPs restored intestinal barrier integrity by up-regulating tight junction proteins Claudin-1, Occludin, and Zonula Occludens-1 (ZO-1). 16S rRNA analysis revealed that LBSPs reversed gut microbiota dysbiosis, enriching Lactobacillus, Ligilactobacillus, Rikenella, Lachnospiraceae_NK4A136_group, while decreasing Escherichia-Shigella and Klebsiella.

Mitophagy, as a selective autophagy, is reported to be involved in the regulation of liver injury. Sinensetin, a polymethoxylated flavonoid abundant in citrus fruit peels, exhibits various biological activities, including anti-inflammatory and hepatoprotective properties. However, whether sinensetin can target mitophagy and protect against HFD-induced liver damage via the gut-liver axis remains inadequately explored. In order to further investigate the relationships involved, we conducted histopathology analysis, biochemical analysis, 16S rRNA sequencing, and short-chain fatty acid (SCFA) levels. Sinensetin administration ameliorated hepatic steatosis, inflammation, and restored intestinal integrity in HFD-fed mice. Mechanistically, sinensetin remodeled the gut microbiota, elevating SCFA levels, which activated mitophagy and cleared damaged mitochondria in liver and intestinal tissues, thereby suppressing the toll-like receptor 4 (TLR4)/mitogen-activated protein kinase (MAPK) signaling.

Despite its growing global burden, no widely approved pharmacotherapy is available, highlighting the need to elucidate immunometabolic mechanisms and identify effective therapeutic targets. This review summarizes the epidemiology and clinical features of MASH and focuses on key pathogenic pathways, including insulin resistance, lipotoxicity, mitochondrial dysfunction, and gut-liver axis disturbance. Immune dysregulation mediated by Kupffer cell activation, macrophage polarization, inflammasome signaling, and cytokine networks is discussed in depth.

This study evaluated whether enzymatically prepared Solenocera crassicornis peptides (SCPs) provide additional benefits during diet normalization in HFD-induced obese mice and examined associations with antioxidant, microbial, and barrier markers. Methods: SCPs were characterized using UPLC-Q-TOF-MS/MS and amino acid analysis. Peptides underwent bioactivity prediction and Keap1 docking. After 7 weeks of HFD feeding, obese male C57BL/6J mice were switched to a normal diet and administered vehicle, orlistat, or SCPs for 4 weeks. Adipose tissue mass, serum lipid profiles, liver histology, hepatic antioxidant status, barrier-associated histological and biochemical markers, and gut microbiota composition were assessed. A simulated digestion-fecal fermentation model was used to assess the effects of fermentation products generated in the presence of digested SCPs on H2O2-induced oxidative injury and MUC2 secretion in LS174T goblet-like cells. Results: SCPs reduced epididymal and perirenal fat, improved serum lipids, improved hepatic steatosis-related morphology and enhanced hepatic antioxidant status. SCPs were also associated with improved intestinal morphology, increased mucin-associated staining, decreased serum diamine oxidase levels and reduced hepatic lipopolysaccharide accumulation. 16S rRNA sequencing showed SCP-associated microbial shifts, with correlations linking taxa to metabolic and barrier markers. Fermentation products generated in the presence of digested SCPs improved oxidative-stress and MUC2-related readouts in LS174T cells.

We extracted and characterized DOP. We established a rat model of NAFLD induced by HFD and evaluated the efficacy of DOP by integrating multi-omics techniques (transcriptomics, metabolomics) and 16S rRNA sequencing. To verify the specific role of SIRT6, we introduced the SIRT6 inhibitor OSS_128167 in the primary hepatocyte model induced by oleic acid/palmitic acid (OA/PA). DOP significantly alleviated liver steatosis, oxidative stress, and lipid metabolism disorders induced by HFD. Multi-omics analysis indicated that DOP regulated liver glycerophospholipid metabolism and restored intestinal microbiota homeostasis, significantly increasing the abundance of beneficial bacteria such as Lactobacillus. Mechanistically, DOP activated the liver SIRT6/PGC-1α signaling axis, thereby enhancing antioxidant defense and inhibiting lipogenesis. Crucially, in vitro experiments confirmed that the SIRT6 inhibitor OSS_128167 eliminated the protective effect of DOP on lipid accumulation, confirming that the effect of DOP depends on SIRT6.

In traditional Chinese medicine, Huanglian Wendan Decoction (HLWDD) is prescribed for phlegm-heat and damp-heat syndromes affecting the gallbladder and stomach and is traditionally used to clear heat, dry dampness, and resolve phlegm. It is commonly applied in the treatment of phlegm-heat-related metabolic disorders, including fatty liver disease. However, the therapeutic effects of HLWDD and the contributions of its key constituents to MASH remain to be further elucidated. This study aimed to evaluate the anti-inflammatory and lipid-regulatory effects of HLWDD and its key components in MASH and to explore the underlying molecular mechanisms. Male C57BL/6 J mice were given a methionine-choline-deficient (MCD) diet and received HLWDD in either low or high doses through oral gavage, with fenofibrate serving as a positive control. Body weight, liver index, serum levels of alanine aminotransferase and aspartate aminotransferase, serum lipid profiles, and hepatic triglyceride and total cholesterol contents were among the evaluated parameters. H&E, Oil Red O, and Masson's trichrome staining were used to evaluate histopathological changes. Hepatic macrophage infiltration was examined by immunofluorescence, inflammatory cytokines were measured by ELISA, and key signaling and lipid metabolism-related proteins were analyzed by western blotting. UPLC‒MS/MS was used to characterize the chemical profile of the HLWDD granules and identify their major constituents. Network pharmacology analysis integrating multiple databases, together with GO and KEGG enrichment analyses, was performed to predict potential targets and pathways. Molecular docking and molecular dynamics simulations were further used to investigate compound‒target interactions. Cell viability in vitro was measured with CCK-8 assays, protein levels were confirmed through western blotting, and intracellular lipid buildup was assessed using Oil Red O staining. UPLC‒MS/MS analysis revealed that berberine (BBR), an isoquinoline alkaloid, is a major bioactive component of HLWDD. Network pharmacology analysis suggested that HLWDD and BBR may exert anti-MASH effects by modulating multiple targets and pathways, including IL-6, PPARα, and the NF-κB/HDAC1/SREBP-1c axis. These predictions were supported by in vivo experiments, which confirmed the protective effects of HLWDD against MASH. Both in vivo and in vitro studies further revealed that BBR markedly ameliorated MASH-related phenotypes by suppressing the NF-κB/HDAC1/SREBP-1c axis. Additionally, simulations of molecular docking and dynamics revealed stable interactions between BBR and important proteins within this axis. Microscale thermophoresis (MST) assays further demonstrated direct binding of BBR to HDAC1. Collectively, these findings suggest that HLWDD and its key active constituent BBR alleviate MASH, at least in part, by inhibiting the NF-κB/HDAC1/SREBP-1c axis, which is closely associated with inflammatory responses and dysregulated lipogenesis. HLWDD markedly ameliorated the MASH phenotype by attenuating hepatic inflammation and lipogenesis, with the NF-κB/HDAC1/SREBP-1c axis emerging as a key mechanism linking inflammatory signaling to aberrant lipid synthesis. BBR, identified by UPLC‒MS/MS as a major active constituent of HLWDD, largely recapitulated these effects and directly bound to HDAC1, supporting its important contribution to the protective effects of HLWDD against MASH."},{"quote":"After screening, Egfr, Hmox1, and Lgmn were identified as biomarkers.","source_id":"42393642","status":"PASS","error":"","abstract_text":"ID: 42393642\nTitle: MCD biomarkers Egfr, Hmox1, Lgmn identified in NAFLD.\nAbstract: Non-alcoholic fatty liver disease (NAFLD) is associated with metabolic cell death (MCD), and this study aimed to dig deeper into the biomarkers associated with MCD in NAFLD, and to provide new references for the diagnosis and treatment of NAFLD. The datasets and MCD-related genes (MCD-RGs) associated with NAFLD were downloaded from the Gene Expression Omnibus (GEO) database and the literature, respectively. Differentially expressed genes (DEGs) between NAFLD and control groups were identified and intersected with MCD-RGs to yield candidate genes. Biomarkers were obtained by screening under four machine learning models, Receiver Operating Characteristic (ROC) curves, and expression validation. Based on the biomarkers, functional enrichment, diagnostic model construction, network modulation, and reverse transcription-quantitative polymerase chain reaction (RT-qPCR) were performed. At the same time, differential infiltration of immune cells in the NAFLD and control groups was analysed. The 17 candidate genes were mostly involved in processes such as immunity and apoptosis. After screening, Egfr, Hmox1, and Lgmn were identified as biomarkers. Among these, Egfr was down-regulated whereas Hmox1 and Lgmn were up-regulated in NAFLD. Based on these biomarkers, a nomogram diagnostic model was constructed and demonstrated excellent predictive performance (AUC = 0.997). Subsequent enrichment analyses showed enrichment in inflammatory regulation between biomarkers and NAFLD groups. In addition, in the TF-biomarker network, Egfr and Hmox1 co-predicted NF-κB1.

Lophatherum gracile Brongn. (L. gracile) is rich in various bioactive components, including flavonoids and polysaccharides. This study established a DES-based extraction system for flavonoids of L. gracile, optimized the process using response surface methodology, and evaluated the antioxidant activity, and hepatoprotective effects of the extracts against alcoholic liver disease (ALD) with focus on gut microbiota modulation. A choline chloride-malic acid DES was identified as the optimal extractant. Under the optimized conditions (extraction time of 60 min, water content of 32%, liquid-to-solid ratio of 61:1 mL/g, molar ratio of 1:1, ultrasonic power of 480 W, and temperature of 60°C), the extraction yield of L. gracile flavonoids reached 16.62 ± 0.27 mg/g. Compared to traditional ethanol extracts, the DES-extracted L. gracile flavonoids exhibited significantly stronger DPPH radical scavenging activity. Moreover, they demonstrated enhanced hepatoprotective effects in an ALD mouse model by ameliorating dyslipidemia, alleviating liver injury, and improving hepatic histopathology.

Understanding the underlying metabolic pathways offers valuable insights into disease progression and potential therapeutic approaches. Dysregulation of the gut-liver axis and microbial imbalance contribute to MASLD progression by compromising intestinal barrier integrity, altering microbe-mediated metabolites, and promoting chronic hepatic inflammation. However, the specific metabolic disruptions in MASLD and the mechanisms through which microbes and their metabolites influence liver injury remain poorly understood. Six-week-old C57BL/6J mice were randomly assigned to five groups: baseline, normal chow (NC)_8w, NC_16w, MASLD_8w, and MASLD_16w. Mice in the MASLD groups were fed a high-fat diet (HFD), while the control groups were fed an NC diet. Body weight, liver function, and histopathological changes were evaluated, along with hepatic metabolomic profiling and fecal 16S ribosomal RNA gene sequencing. HFD-fed MASLD mice exhibited significant liver dysfunction, hepatic lipid accumulation, and increased body weight, triglycerides (TG), and cholesterol (CHO). Metabolomic analysis revealed marked disruption of hepatic metabolic homeostasis, particularly in lipid metabolism. Arachidonic acid metabolism was significantly altered and accompanied by increased levels of inflammatory mediators, including arachidonic acid (AA) and prostaglandin E2. In parallel, the relative abundance of Enterobacteriaceae was elevated in MASLD mice and showed a significant positive correlation with the hepatic accumulation of phosphatidylcholine (PC) (18:4(6Z,9Z,12Z,15Z)/16:1(9Z)), a phosphatidylcholine species annotated as a potential precursor of arachidonic acid. This coordinated alteration in gut microbial composition and hepatic lipid metabolites was associated with hepatic inflammatory responses in MASLD. Our findings demonstrate that hepatic inflammatory activation in MASLD is closely associated with reprogramming of the AA metabolic pathway. The observed Enterobacteriaceae-PC-AA correlation provides a potential mechanistic explanation for gut-liver crosstalk in MASLD progression, and may serve as a promising non-invasive biomarker candidate and therapeutic target for further functional validation."},{"quote":"Application of advanced delivery systems, which increase oral bioavailability by up to 20-fold, overcomes pharmacokinetic bottlenecks.","source_id":"42354127","status":"PASS","error":"","abstract_text":"ID: 42354127\nTitle: Flavonoids as Nutraceuticals to Treat Inflammatory Diseases: Focusing on Quercetin, Kaempferol, Luteolin, Apigenin, Epicatechin and Their Effects on Hepatic, Nervous, and Pulmonary Systems.\nAbstract: The immune response is essential in the protection of our body against pathogens; however, the inflammatory response caused by the immune system can become a disease itself. In fact, anti-inflammatory and immune-suppressive drugs are applied to limit the immune response to treat inflammatory diseases. Flavonoids are plant-derived polyphenols extensively investigated for their anti-inflammatory and antioxidant properties in inflammatory diseases. Studies applying isolated compounds as well as using supplements as nutraceuticals based on flavonoids have been conducted. Our review systematically analyzed the top five studied flavonoids between 2020 and 2025: quercetin (1742 articles), kaempferol (642), luteolin (589), apigenin (419), and epicatechin (354), highlighting their major therapeutic applications in diseases affecting the liver (12%), nervous system (11%), and lungs (10%). Mechanistically, these compounds act as multi-target agents mainly by inhibiting NF-κB and inducing Nrf2-dependent antioxidant programs. Application of advanced delivery systems, which increase oral bioavailability by up to 20-fold, overcomes pharmacokinetic bottlenecks. Clinical highlights demonstrated promising therapeutic effects, including reduced intrahepatic lipid accumulation in non-alcoholic fatty liver disease patients following quercetin supplementation (11.5% to 9.6%) and accelerated SARS-CoV-2 clearance after quercetin phytosome administration.

As a disease involving complex pathogenic mechanisms, NAFLD has become the most prevalent chronic liver disease and may progress to more severe conditions. Pyroptosis is a pro-inflammatory form of programmed cell death that is distinct from classical apoptosis. Accumulating evidence suggests that pyroptosis plays a role in the pathogenesis of NAFLD, contributing to disease progression from simple hepatic steatosis to non-alcoholic steatohepatitis (NASH) and fibrosis. Excessive activation of pyroptosis can exacerbate inflammatory responses, induce cellular damage, disrupt immune homeostasis, and impair liver function. Therefore, elucidating the mechanisms and roles of pyroptosis in NAFLD is crucial for the development of effective therapeutic strategies. As a key transcription factor, nuclear factor erythroid 2-related factor 2 (NRF2) has emerged as a promising therapeutic target. Pharmacological modulation of NRF2 has shown potential in treating diseases characterized by oxidative stress and inflammation. Findings from in vitro and animal studies suggest that various compounds that target NRF2 to modulate pyroptosis exhibit notable effects on the initiation and progression of NAFLD. Although most of these agents are still in the early stages of preclinical research, they hold substantial promise for future clinical translation. This review outlines recent advances in pyroptosis-related research in NAFLD and highlights pharmacological targeting of NRF2 as a promising therapeutic approach for pyroptosis-mediated NAFLD."},{"quote":"Baicalein, a bioactive flavonoid, possesses well-recognized anti-inflammatory properties, yet its molecular targets in macrophages and potential systemic immunomodulatory effects on peripheral blood immune cells under hyperinflammatory conditions remain poorly characterized.","source_id":"42337165","status":"PASS","error":"","abstract_text":"ID: 42337165\nTitle: Potential targets of baicalein in macrophages revealed by bulk and single cell RNA sequencing analysis.\nAbstract: Excessive inflammation drives organ dysfunction and high mortality in life-threatening conditions such as sepsis.

Our previous studies demonstrated that baicalein alleviates hepatic inflammation in mice with non-alcoholic fatty liver disease (NAFLD) and inhibits NF-κB nuclear translocation in RAW264.7 macrophages. Here, by integrating network pharmacology, molecular docking, bulk RNA sequencing of macrophages, and single-cell RNA sequencing of peripheral blood from sepsis patients, we identified JAK2, SRC, TP53, MAPK3, AKT1, HSP90AA1, and ESR1 as potential core targets of baicalein in macrophages, and validated that the JAK2-STAT3 and NF-κB pathways might be the key downstream regulatory axes of its anti-inflammatory effects. Furthermore, we revealed that baicalein may modulate, based on single-cell expression signatures, the inflammatory phenotype of multiple peripheral blood immune cell populations, including monocytes, T cells, B cells, and granulocyte-monocyte progenitors, suggesting a potential systemic anti-inflammatory effect that requires experimental validation in human cells.

Therefore, an alternative mechanism might work to counteract the lipid-lowering effect of PPARα agonist. As fatty acids can also be metabolized in peroxisome and the acetyl-CoA generated in peroxisomal β-oxidation could be used for the biosynthesis of malonyl-CoA, a critical molecule in controlling mitochondria fatty acid oxidation. We hypothesize that peroxisomal β-oxidation might play a role in regulating mitochondrial fatty acid oxidation through mediating malonyl-CoA formation. This study demonstrates a counteracting mechanism by which induction of peroxisomal β-oxidation causes suppression of mitochondrial fatty acid oxidation in animals administered with PPARα agonist. PPARα agonist induces oxidation of fatty acids by peroxisomes and generates considerable acetate in the liver, which significantly elevates hepatic content of malonyl-CoA, and causes suppression of mitochondrial β-oxidation. Specific inhibition of peroxisomal β-oxidation enhances mitochondrial fatty acid oxidation and attenuates hepatic lipid accumulation by reducing acetate and malonyl-CoA formation in the mice treated with PPARα agonist.

In this study, we propose a novel dietary therapy for NAFLD utilizing a conjugate of chitooligosaccharide (COS) and epigallocatechin gallate (EGCG), as the underlying mechanisms of NAFLD remain unclear. NAFLD was induced in male Wistar rats by administering a high-fat diet (HFD) for 16 weeks, followed by administration of COS-EGCG conjugate (150, 300, and 600 mg/kg) for an additional four weeks. The treatment alleviated metabolic parameters, liver steatosis, and injury. It also reduced hepatic lipid accumulation by downregulating the expression of CD36, fatty acid synthase (FASN), and sterol regulatory element-binding protein 1c (SREBP-1c), while upregulating peroxisome proliferator-activated receptor alpha (PPARα), carnitine palmitoyltransferase 1 A (CPT1A), and microsomal triglyceride transfer protein (MTTP). Regarding the gut-liver axis, the conjugate modulated gut microbiota, reduced serum lipopolysaccharide (LPS) levels, and restored the expression of intestinal tight junction proteins (zonula occludens-1; ZO-1 and occludin).

Current treatments, including ursodeoxycholic acid, have shown limited efficacy, underscoring the need for more effective therapies. Chlorogenic acid (CGA), a polyphenolic compound with antioxidant, anti-inflammatory, and hepatoprotective properties, has shown promise in managing liver diseases, but its role in ICP remains poorly understood.

CGA treatment significantly reduced liver enzyme levels, total bile acids, and bilirubin, while improving histopathological liver damage. CGA also modulated key proteins involved in bile acid synthesis and transport, including FXR, CYP7A1, NTCP, and BSEP. Additionally, CGA treatment improved intestinal barrier function by upregulating tight junction proteins, including ZO-1. Metabolomics and 16S rRNA gene sequencing revealed that CGA treatment restored gut microbiota balance in ICP rats.

This study investigated the effects of aerobic exercise on hepatic oxidative stress in an experimental model of obesity-associated NAFLD. Newly weaned Wistar rats were fed a highly palatable, obesity-inducing diet. After obesity was established, the animals were randomly assigned to either a trained group (n=12) or a sedentary group (n=12). The trained group underwent moderate-intensity treadmill running for eight weeks. Hepatic lipid peroxidation was assessed using the TBARS (thiobarbituric acid reactive substances) assay. Aerobic training significantly reduced hepatic TBARS levels (P<0.0005), in an average of 1.8 nmol MDA/mg protein compared to the sedentary group. These benefits were significant regardless of weight gain maintenance. The findings suggest that regular physical exercise attenuates hepatic lipid peroxidation in an experimental model of obesity-associated NAFLD. The results support that physical exercise is an effective non-pharmacological strategy for modulating oxidative stress and preventing disease progression.

The bidirectional nature of this axis implies that treatments focusing on lipid metabolism and inflammatory pathways often result in secondary restoration of gut microbiota composition and intestinal barrier function.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe pathophysiology of metabolic dysfunction-associated fatty liver disease (MASLD) involves complex crosstalk between the liver and the gut, mediated by metabolites, inflammatory cytokines, and hormonal signaling. Evidence demonstrates that the liver can influence gut health; for instance, \"hepatic alkaline phosphatase released from diseased liver suppresses intestinal stem cell differentiation into GLP-1-secreting L-cells.\" Conversely, many therapeutic interventions for fatty liver disease focus on rebalancing this axis. Bioactive compounds like LBSPs have been shown to be effective, as \"LBSPs restored intestinal barrier integrity by up-regulating tight junction proteins Claudin-1, Occludin, and Zonula Occludens-1 (ZO-1).\" Furthermore, systemic metabolic improvement achieved through pharmacological means or natural compounds often leads to gut-level benefits. For example, \"Sinensetin administration ameliorated hepatic steatosis, inflammation, and restored intestinal integrity in HFD-fed mice.\" Therapeutic approaches must address the \"complex coupling of metabolic imbalance and immune-driven inflammation, making single-target therapy insufficient.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Hepatic alkaline phosphatase acts as a regulatory node that can inhibit the production of GLP-1 secreting cells in the intestine.\n*   Certain medicinal extracts, like those from *Lophatherum gracile*, can reshape alcohol-disturbed gut microbiota by increasing *Akkermansia* and *Lactobacillus*.\n*   Maternal butyrate administration during gestation can prevent the programming of fetal fatty liver disease, illustrating the developmental window of the gut-liver axis.\n*   Exercise serves as a potent non-pharmacological modulator that attenuates hepatic lipid peroxidation even without significant weight loss.\n*   Specific biomarkers, such as EGFR, HMOX1, and LGMN, have been identified as having transcriptomic correlation with metabolic cell death in NAFLD.\n*   The use of deep eutectic solvents for extracting flavonoids provides a greener, highly efficient methodology for preparing therapeutic agents for ALD.\n*   Intestinal FXR deficiency uncouples steatosis protection from liver inflammation, suggesting that blocking FXR in the gut may limit steatosis while paradoxically promoting distinct inflammatory responses.\n*   Marine-derived peptides, such as those from *Solenocera crassicornis*, are associated with improved mucin-associated staining and barrier integrity during diet normalization.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

While animal studies show that butyrate-producing microbes can improve liver function, full recovery is hindered by unintended side effects from commensal bacteria. These underlying biomolecular mechanisms remain elusive, due to the lack of in vitro coculture models capable of systematically examine both the therapeutic benefits of engineered microbial metabolites and their potential adverse impacts. To address this, we developed a modular microfluidic platform to study the effects of live microbial metabolites on hepatic steatosis and liver function. We created a microfluidic-based hepatic steatosis model integrated with a compartmentalized microbial module, facilitating the study of how metabolites produced by live microbes affected the liver model. We compared the effects of synthetic SCFA supplementation with those of coculturing with a control and butyrate-producing E. coli Nissle 1917 (EcN) strains on hepatic steatosis. Our findings showed that live microbial coculture did not phenocopy exogenous SCFA treatment. While both treatments reduced steatotic lipid accumulation, live microbes induced inflammatory and hepatic metabolic changes, suggesting contributions from additional microbial factors, emphasizing the need to thoroughly assess side effects in liver disease treatment.\n\nID: 42431962\nTitle: Intestinal FXR deficiency uncouples steatosis protection from liver inflammation and fibrosis in MASH-diet fed mice.\nAbstract: The Farnesoid X Receptor (FXR), a nuclear bile acid (BA) receptor highly expressed in the liver and intestine, is a potential pharmacological target for Metabolic dysfunction-Associated SteatoHepatitis (MASH). While intestinal FXR inhibition reduces high-fat diet (HFD)-induced hepatic steatosis, its role in MASH progression remains unclear. This study investigates the impact of intestinal FXR-deficiency on MASH development in a diet-induced murine model. Intestinal FXR-deficient (intFXR KO) and control mice were fed a high-fat, sucrose, and cholesterol-enriched diet (HFSC) for 24 weeks. Intestinal immune phenotyping, microarray, 16 S rRNA sequencing, bile acid quantification and liver assessments (histology, biochemistry and single-cell RNA sequencing (scRNA-seq)) were performed. intFXR KO mice were protected against HFSC diet-induced obesity and hepatic steatosis but exhibited altered expression of intestinal barrier-associated genes, with increased cytotoxic CD8+ T-lymphocytes. Microbiota composition and bile acid profiles were altered, including reduced Lachnospiraceae species correlating negatively with liver hyocholic acid levels. Despite a protection against hepatic steatosis, liver inflammation and fibrosis were unchanged in intFXR KO mice. Transcriptomic and Immune cell scRNA-seq analysis revealed alteration in immune-related pathways with an increased neutrophil proportion and higher cDC1:cDC2 and CD4:CD8 T cell ratios. Thus, intestinal FXR-deficiency limits steatosis but promote a distinct hepatic immune-inflammatory response and does not prevent progression to MASH.\n\nID: 42428317\nTitle: Herbal medicines modulate gut microbiota in metabolic diseases: a review.\nAbstract: Metabolic diseases-including obesity, type 2 diabetes mellitus (T2DM), and non-alcoholic fatty liver disease (NAFLD)-affect over 1 billion individuals globally and are characterized by insulin resistance, chronic inflammation, and gut microbiota dysbiosis. Herbal medicines offer multi-component therapeutic potential through microbiota modulation, but mechanistic insights remain fragmented. This review synthesizes recent advances in herbal medicine-mediated gut microbiota regulation in metabolic diseases and delineates underlying molecular mechanisms. A comprehensive literature search was conducted across PubMed and Web of Science. Search strategies employed MeSH terms and free-text keywords encompassing herbal medicines, gut microbiota, and metabolic diseases. Two authors performed study selection and data extraction. Evidence synthesis was structured according to intervention type and metabolic disease category. Herbal polysaccharides and other compounds consistently increased beneficial bacteria and promoted short-chain fatty acids (SCFAs) production, improving intestinal barrier integrity via ZO-1/Occludin upregulation and attenuating TLR4/NF-κB-mediated inflammation. Herbal formulations exerted synergistic effects by remodeling microbial community structure, correcting SCFA/bile acid imbalances, and activating IRS1/PI3K/AKT insulin signaling. Notably, Lactobacillus and Akkermansia emerged as recurrent beneficial targets across multiple herbal interventions. However, evidence is predominantly preclinical, and translational validity to humans requires further validation. Herbal medicines ameliorate metabolic diseases through multi-target gut microbiota modulation, involving SCFA production, bile acid metabolism, and inflammatory pathway attenuation. These mechanistic insights support the development of microbiota-targeted herbal therapeutics, though clinical translation necessitates standardized formulations and rigorous human trials.\n\nID: 42421922\nTitle: Sinensetin ameliorates established high-fat diet-induced liver injury and intestinal barrier dysfunction through the mitophagy/TLR4/MAPK signaling pathway.\nAbstract: Long-term consumption of a high-fat diet (HFD) causes liver injury characterized by steatosis, inflammation, and fibrosis. Mitophagy, as a selective autophagy, is reported to be involved in the regulation of liver injury. Sinensetin, a polymethoxylated flavonoid abundant in citrus fruit peels, exhibits various biological activities, including anti-inflammatory and hepatoprotective properties. However, whether sinensetin can target mitophagy and protect against HFD-induced liver damage via the gut-liver axis remains inadequately explored. In order to further investigate the relationships involved, we conducted histopathology analysis, biochemical analysis, 16S rRNA sequencing, and short-chain fatty acid (SCFA) levels. Sinensetin administration ameliorated hepatic steatosis, inflammation, and restored intestinal integrity in HFD-fed mice. Mechanistically, sinensetin remodeled the gut microbiota, elevating SCFA levels, which activated mitophagy and cleared damaged mitochondria in liver and intestinal tissues, thereby suppressing the toll-like receptor 4 (TLR4)/mitogen-activated protein kinase (MAPK) signaling. Sinensetin may contribute to protecting against HFD-induced liver injury and intestinal barrier dysfunction by orchestrating the integrated \"microbiota-SCFA-mitophagy\" defensive network, providing a novel paradigm beyond the classical TLR4/MAPK axis.\n\nID: 42409325\nTitle: Dysregulation of the bile acid signaling network in non-alcoholic fatty liver disease: Mechanisms and a new paradigm of precision network pharmacology.\nAbstract: Non-alcoholic fatty liver disease (NAFLD) has emerged as the most prevalent chronic liver disease worldwide, characterized by complex pathogenesis and a lack of effective therapies. The bile acid (BA) \"synthesis-transport-signaling\" axis serves as a central hub integrating gut microbiota, host metabolism, and immunity, and its network dysregulation is a key driver of NAFLD progression. This review systematically elaborates how dysfunction of key enzymes, transporters, and receptors (e.g., farnesoid X receptor (FXR), Takeda G protein-coupled receptor 5 (TGR5)) within this axis drives hepatic steatosis, inflammation, and fibrosis by reshaping the BA pool, disrupting enterohepatic circulation, and perturbing receptor cross-talk. Current pharmacological strategies targeting single nodes are constrained by interspecies differences in BA profiles, network complexity, and off-target effects, posing significant challenges to their efficacy and safety. Consequently, we propose a paradigm shift from \"single-target\" approaches towards \"precision network pharmacology.\" This entails developing novel bile acid conjugates, dual-target or multi-target agents, designing rational combination therapies, and stratifying patients based on their BA metabolic phenotypes. Guided by human-relevant models and novel biomarkers, this framework aims to systemically restore BA signaling network homeostasis and enable personalized intervention, offering a novel theoretical and translational roadmap for conquering NAFLD.\n\nID: 42404798\nTitle: Synergistic modulation of the gut microbiome-liver-host metabolome axis associates with the therapeutic efficacy of Danlou tablet against metabolic syndrome.\nAbstract: Obesity drives chronic diseases such as cardiovascular disease and diabetes. Danlou tablet (DLT), a traditional Chinese medicine formula, is used to treat coronary heart disease by regulating lipid metabolism, suggesting potential for addressing obesity-related metabolic dysfunction. However, its role in obesity and insulin resistance remains unexplored. We investigated the efficacy and mechanisms of DLT against high-fat diet (HFD)-induced obesity and insulin resistance. C57BL/6N mice were fed an HFD for 22 weeks and treated with DLT. A comprehensive phenotypic assessment was conducted, including body weight, glucose tolerance, insulin sensitivity, serum biochemistry, and histopathology of key tissues. To elucidate the therapeutic mechanism, we integrated 16S rRNA gene sequencing of gut microbiota, serum metabolomics (UPLC-Q-TOF-MS), and hepatic transcriptomics. DLT treatment counteracted HFD-induced metabolic dysfunction, reducing body weight, adiposity, dyslipidemia, and insulin resistance, while ameliorating hepatic steatosis, inflammation, and oxidative stress. At the microbial level, DLT restored gut microbial diversity, corrected the Firmicutes/Bacteroidota ratio, and modulated key genera. Metabolomics linked these changes to restored fatty acid β-oxidation. In the liver, transcriptomics showed that DLT reversed HFD-induced gene expression, suppressed inflammatory pathways and enhanced fatty acid oxidation and xenobiotic metabolism. Integrated multi-omics analysis revealed a strong correlative relationship that DLT's therapeutic benefits are associated with the modulation of the gut-liver axis, where remodeling of the gut microbiome is closely linked to the reprogramming of hepatic metabolic pathways. DLT counteracts HFD-induced obesity and insulin resistance via a multi-level regulatory mechanism that is closely associated with the modulation of the gut-liver axis, which involves suppressing pathogenic gut microbes, restoring fatty acid metabolism, and enhancing hepatic lipid catabolism and antioxidant defense. This comprehensive preclinical evidence supports the clinical translation of DLT as a novel therapeutic option for obesity and type 2 diabetes mellitus.\n\nID: 42395007\nTitle: Korean red ginseng extract ameliorates high-fat diet-induced hyperlipidemia by modulating the gut microbiota-liver metabolic axis.\nAbstract: Korean Red Ginseng is recognized for its ability to modulate immune responses, alleviate fatigue, and combat aging, and shows promise in treating hyperlipidemia. However, comprehensive insights into its gut-liver axis mechanisms remain limited. Rats were assigned to a normal control group, an HFD-fed model group, and four groups treated with Korean Red Ginseng extract (RGE) at doses of 125 mg/kg, 250 mg/kg, 500 mg/kg, and 1000 mg/kg. The treatment groups administered RGE by gavage for 60 days while on an HFD. The study evaluated RGE's effects on hyperlipidemia and gut microbiota through serum biochemical analysis, hepatic histopathology, cecal metabolomics, 16S rRNA sequencing, and further investigated hepatic regulatory mechanisms using molecular biology techniques. After 60 days of treatment, RGE significantly reduced serum lipid levels and liver injury markers. Histological analysis using H&E and Oil Red O staining showed that RGE significantly reduced hepatic steatosis in comparison to the model group. LC-MS and 16S rRNA sequencing of cecal contents revealed that RGE remodeled gut microbiota composition, enhancing microbiota-derived metabolite production. Molecular analysis indicated that RGE activated hepatic PPARα, downregulated SREBP-1c, and partially restored basal cholesterol biosynthesis by upregulating HMGCR mRNA. These changes collectively reduced hepatic triglyceride accumulation and promoted cholesterol excretion. RGE alleviates HFD-induced hyperlipidemia and hepatic steatosis through a coordinated gut-liver axis mechanism, involving microbiota modulation, metabolic reprogramming, and regulation of hepatic lipid factors. These findings support RGE as a potential therapeutic option for hyperlipidemia and related metabolic disorders, using an \"excretion-centric\" strategy.\n\nID: 42395006\nTitle: Microbiome-mediated pharmacology of ginseng: Mechanistic insights into metabolic regulation and therapeutic potential.\nAbstract: Ginseng, a traditional medicinal herb with a favorable safety profile, has long been used to promote systemic health. Recent studies reveal that many of its beneficial effects are mediated through interactions with the gut microbiota. Microbial enzymes convert parent ginsenosides into more absorbable and bioactive metabolites such as compound K, while ginseng reciprocally remodels the microbial community and metabolite composition by promoting the growth of beneficial taxa including Akkermansia, Bifidobacterium, and Lactobacillus. These bidirectional interactions modulate host metabolic, immune, and intestinal barrier functions. The ginseng-microbiome interplay regulates microbial and host-derived metabolites such as short-chain fatty acids, bile acids, and indole derivatives, which in turn activate key signaling pathways including FXR/TGR5, FFAR, AMPK, and Nrf2. Through these mechanisms, ginseng improves lipid metabolism, enhances insulin sensitivity, alleviates low-grade inflammation, and ameliorates metabolic abnormalities such as obesity, insulin resistance, and nonalcoholic fatty liver disease (NAFLD). This review provides a comprehensive synthesis of the ginseng-microbiota metabolic axis, focusing on its mechanistic basis in metabolic regulation and related disorders. We also highlight the therapeutic convergence between ginseng and probiotics possessing ginsenoside-hydrolyzing enzymes, discuss strategies for strain selection and co-administration, and outline future directions in precision, microbiome-informed formulations and clinical trial design. Collectively, current evidence supports the ginseng-microbiota interactions as a promising therapeutic platform for restoring metabolic homeostasis and managing metabolic diseases.\n\nID: 42389066\nTitle: Metabolic Dysfunction-Associated Fatty Liver Disease: From Pathogenesis to Treatment.\nAbstract: Metabolic dysfunction-associated fatty liver disease (MAFLD) has become the most prevalent chronic liver disease worldwide and represents a major hepatic manifestation of systemic metabolic dysfunction. The disease is closely linked to obesity and insulin resistance and progresses from simple hepatic steatosis to metabolic dysfunction-associated steatohepatitis, fibrosis, cirrhosis, and hepatocellular carcinoma. Increasing evidence indicates that MAFLD pathogenesis involves complex interactions among dysregulated lipid metabolism, mitochondrial dysfunction, oxidative stress, inflammatory signaling, bile acid imbalance, and gut microbiota-derived metabolites, reflecting the systemic and multifactorial nature of the disease. However, despite substantial progress in understanding these mechanisms, the integrated regulatory networks driving MAFLD progression and their translational therapeutic implications remain incompletely characterized. In this review, we comprehensively summarize recent advances in the molecular mechanisms underlying MAFLD, focusing on metabolic dysregulation, cellular stress responses, inflammatory pathways, and regulated cell death processes. We further highlight the critical role of interorgan communication particularly the adipose-liver and gut-liver axes and discuss emerging evidence on extracellular vesicles (EVs) as mediators of metabolic and inflammatory signaling. Finally, we evaluate current and potential therapeutic strategies, emphasizing the diagnostic and therapeutic promise of EV-based approaches in MAFLD management, and identifying emerging molecular targets for improved intervention and future clinical translation opportunities.\n\nID: 42387035\nTitle: Tirzepatide as a multi-organ integrator in metabolic diseases: a review of molecular mechanisms and clinical translation.\nAbstract: Metabolic diseases, including type 2 diabetes mellitus (T2DM), obesity, dyslipidemia, Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD), and obstructive sleep apnoea (OSA), are characterized by a complex and interconnected pathophysiological syndrome. These conditions involve insulin resistance, chronic inflammation, and disturbances in energy homeostasis. Typically, they affect multiple organs and require comprehensive treatment. This narrative review examines the multi-organ effects of tirzepatide, a new dual agonist of the glucose-dependent insulinotropic peptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors. Tirzepatide possesses innovative therapeutic properties and targets multiple metabolic pathways. The review incorporates peer-reviewed sources, including clinical trials, preclinical studies, and specialist reviews. Emphasis is placed on tirzepatide's physiological effects on pancreatic β-cells, adipose tissue, the liver, the gastrointestinal tract, the cardiovascular system, the kidneys, the brain, and gut microbiota. Tirzepatide is a dual receptor agonist that increases insulin levels, decreases glucagon levels, slows gastric emptying, and promotes feelings of fullness, contributing to significant weight loss. Recent preclinical studies have shown that tirzepatide can also alter gut microbiota composition, leading to increased Bacteroidetes and decreased Firmicutes. Additionally, tirzepatide has been shown to enhance intestinal barrier integrity. Clinical trial programs, such as SURPASS and SURMOUNT, have demonstrated that tirzepatide provides improved glycemic control and weight loss compared to current treatments. Other benefits include improvements in lipid profiles, reduced hepatic steatosis, and potential protection for the heart and kidneys. Tirzepatide is a multi-organ integrator with a therapeutic effect extending beyond glucose regulation. It can influence bowel hormones, improve metabolic parameters, and facilitate communication between different organs, making it a promising treatment for metabolic disorders. However, its broader clinical applications need to be confirmed through additional real-life studies and extended evaluations.\n\nID: 42385885\nTitle: Alcohol and high-fat diet aggravate colitis-induced liver injury via glucocorticoid/IL-6-SAA1 axis in mice.\nAbstract: Colitis-associated liver injury rarely causes acute mortality, but whether alcohol and a high-fat diet (HFD) aggravate hepatic injury during colitis remains unclear. Here, dextran sulfate sodium (DSS)-induced colitic mice were exposed to alcohol, HFD, or both. Compared with DSS alone, combined HFD and alcohol exposure (DSSHA) caused greater body-weight loss, poorer body condition, and reduced survival. These effects were linked mainly to liver rather than intestinal deterioration, as shown by an increased liver/body-weight ratio, elevated serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST), and severe hepatic steatosis, whereas colon length, colon weight, and intestinal histological injury were not further aggravated. Mechanistically, alcohol-HFD co-exposure impaired the gut-liver axis, reduced intestinal tight-junction proteins, increased gut permeability and circulating lipopolysaccharide (LPS), and promoted hepatic macrophage and neutrophil infiltration with increased interleukin-6 (IL-6). Transcriptomics identified serum amyloid A1 (SAA1) as a highly upregulated acute-phase gene and revealed Toll-like receptor 4 (TLR4) pathway enrichment. TLR4 inhibition TAK-242 significantly improved survival and attenuated liver injury. Multi-omics further showed increased hepatic cortisol and corticosterone, which cooperated with IL-6 to induce SAA1 expression in HepG2 cells. Thus, an IL-6/glucocorticoid-SAA1-TLR4 axis drives alcohol-HFD-aggravated liver injury in colitis and may represent a therapeutic target.\n\nID: 42385432\nTitle: Polyphenols extracted from Lycium barbarum seeds regulate gut microbiota to improve type 2 diabetes mellitus in db/db mice.\nAbstract: Mounting evidence positions the gut microbiota as a pivotal player in the onset and progression of type 2 diabetes mellitus (T2DM). Lycium barbarum seed polyphenols (LBSPs), a byproduct of Lycium barbarum processing, have shown antioxidant and anti-inflammatory bioactivities, but potential anti-T2DM effects remain unclear. To evaluate the preventive effects of LBSPs against T2DM and the associated gut microbiota mechanisms. The effects of LBSPs on fasting blood glucose, insulin sensitivity, liver lipid accumulation, intestinal barrier, gut microbiota composition, and microbial metabolites were investigated in db/db mice. LBSPs significantly reduced fasting blood glucose, improved insulin sensitivity, and alleviated dyslipidemia and hepatic steatosis in db/db mice. Furthermore, LBSPs restored intestinal barrier integrity by up-regulating tight junction proteins Claudin-1, Occludin, and Zonula Occludens-1 (ZO-1). 16S rRNA analysis revealed that LBSPs reversed gut microbiota dysbiosis, enriching Lactobacillus, Ligilactobacillus, Rikenella, Lachnospiraceae_NK4A136_group, while decreasing Escherichia-Shigella and Klebsiella. Mechanically, LBSPs can modulate aromatic amino acid metabolism, lipid metabolism, and bile acid biosynthesis by metabolomics. Mediation analysis indicated that specific gut microbiota influenced host metabolic parameters through metabolites such as 7-megastigmene-3,6,9-triol 9-glucoside. Our findings reveal that LBSPs can be used as a potential microbiota-targeted nutraceutical that reverses gut microbiota dysbiosis and diabetes-associated metabolic disorders during T2DM progression.\n\nID: 42377574\nTitle: Butyrate ameliorates maternal high-fat-diet-induced placental inflammation and offspring metabolic dysfunction via modulating gut microbiota in mice.\nAbstract: Maternal high-fat diet (HFD) increases the risk of metabolic disorders in offspring. Placental inflammation acts as a critical mediator with poorly addressed etiology. Recently HFD-induced gut dysbiosis is demonstrated to be a key driver of systemic inflammation. Whether inflammatory signals triggered by HFD-induced gut dysbiosis are transmitted to the placenta via the maternal-fetal axis warrant further investigation. This study aims to elucidate the mechanistic connection between maternal gut dysbiosis and placental inflammation, thereby offering insights into microbiota-mediated developmental origins of metabolic diseases in offspring. Female C57BL/6 mice were exposed to high fat diet (HFD) for 5 weeks prior to mating with male mice. Gut microbiota was profiled by using 16 S rRNA sequencing and fecal short-chain fatty acids (SCFAs) were quantified by GC-MS from HFD pregnant mice at gestational day 18.5 (G18.5). Mice were sacrificed at G18.5, and placenta histopathological analysis as well as inflammatory markers and lipopolysaccharide (LPS) level were analyzed. Anti-inflammatory effects of butyrate were evaluated in vitro by using HTR-8/Svneo cells and in vivo through gestational supplementation (0.3 mg/g body weight) in HFD-fed dams. Maternal HFD exposure induced significant placental inflammation as well as hepatic steatosis in the offspring. HFD-fed dams exhibited distinct gut dysbiosis with reduced fecal and serum SCFAs, which was accompanied by elevated placental LPS levels and exacerbated inflammatory responses. Butyrate treatment suppressed the expression of inflammatory cytokines in vitro through down-regulating the phosphorylation of NF-κB, ERK1/2 signaling pathways via G-protein-coupled receptor 41 (GPR41). Furthermore, gestational butyrate intervention effectively alleviated placental inflammation and mitigated fetal hepatic lipid deposition in HFD-exposed offspring. Placental inflammation caused by maternal HFD is closely associated with gut microbiota dysbiosis. Butyrate supplementation during gestation reduces placental inflammation and ameliorated offspring hepatic steatosis, highlighting the therapeutic potential of butyrate for mitigating the adverse metabolic programming effects upon maternal HFD exposure.\n\nID: 42371165\nTitle: The microbiota-mitochondria axis: linking metabolic dysfunction to neurodegeneration.\nAbstract: The interplay between gut microbiota and mitochondria represents a dynamic relationship that profoundly impacts host physiology, ranging from maintaining intestinal homeostasis to regulating systemic metabolic and neurological functions. Microbial metabolites such as short-chain-fatty-acids, bile acids, and amino acid derivatives serve as pivotal modulators of mitochondrial bioenergetics, oxidative stress management, and fission-fusion processes. These interactions are vital for preserving epithelial integrity, supporting energy metabolism, shaping immune responses, and managing inflammatory signaling pathways. Disruptions within this microbiota-mitochondria axis are associated with various pathologies, including non-alcoholic fatty liver disease, obesity, type 2 diabetes, and chronic inflammatory conditions like inflammatory bowel disease. Additionally, growing evidence connects gut dysbiosis and mitochondrial dysfunction to neurodegenerative disorders such as Parkinson's disease and Alzheimer's disease, highlighting the importance of this bidirectional relationship in maintaining neuronal health. On a mechanistic level, pathways involving AMPK, sirtuins, and PGC-1α govern mitochondrial biogenesis and adaptive responses to microbial signals. Dysregulation of these pathways can heighten oxidative stress, hinder mitophagy, and contribute to systemic inflammation. Emerging therapeutic strategies aim to target this axis through dietary modifications, probiotics and engineered microbes, FMT, and mitochondria-specific pharmacological treatments. These interventions focus on restoring metabolic stability, enhance resilience against oxidative damage, and slowing disease progression. By integrating insights from fields such as metabolism, immunology, and neuroscience, this review positions the microbiota-mitochondria axis as a critical area of focus in biomedical research. A deeper understanding of this communication network offers promising opportunities for precision therapies aimed at addressing metabolic, inflammatory, and neurodegenerative diseases.\n\nID: 42356415\nTitle: Marine Peptides from Solenocera crassicornis Are Associated with Improved Metabolic, Hepatic, and Intestinal Markers During Diet Normalization in HFD-Induced Obese Mice.\nAbstract: Background/Objectives: Obesity-associated metabolic dysfunction involves oxidative stress, gut barrier impairment, and gut-liver axis disruption. This study evaluated whether enzymatically prepared Solenocera crassicornis peptides (SCPs) provide additional benefits during diet normalization in HFD-induced obese mice and examined associations with antioxidant, microbial, and barrier markers. Methods: SCPs were characterized using UPLC-Q-TOF-MS/MS and amino acid analysis. Peptides underwent bioactivity prediction and Keap1 docking. After 7 weeks of HFD feeding, obese male C57BL/6J mice were switched to a normal diet and administered vehicle, orlistat, or SCPs for 4 weeks. Adipose tissue mass, serum lipid profiles, liver histology, hepatic antioxidant status, barrier-associated histological and biochemical markers, and gut microbiota composition were assessed. A simulated digestion-fecal fermentation model was used to assess the effects of fermentation products generated in the presence of digested SCPs on H2O2-induced oxidative injury and MUC2 secretion in LS174T goblet-like cells. Results: SCPs reduced epididymal and perirenal fat, improved serum lipids, improved hepatic steatosis-related morphology and enhanced hepatic antioxidant status. SCPs were also associated with improved intestinal morphology, increased mucin-associated staining, decreased serum diamine oxidase levels and reduced hepatic lipopolysaccharide accumulation. 16S rRNA sequencing showed SCP-associated microbial shifts, with correlations linking taxa to metabolic and barrier markers. Fermentation products generated in the presence of digested SCPs improved oxidative-stress and MUC2-related readouts in LS174T cells. Conclusions: During diet normalization, SCPs were associated with additional improvements in adiposity, lipid profiles, hepatic antioxidant status, intestinal barrier readouts, and gut microbiota. These findings support further investigation of SCPs as standardized marine protein hydrolysates, but active components, causal mechanisms, long-term efficacy, safety, and human relevance remain to be established.\n\nID: 42356241\nTitle: Dietary α-Tocopherol Deficiency Disrupts Hepatic Circadian Clock and Lipid Metabolism in Association with Gut Microbiota Dysbiosis.\nAbstract: Background/Objectives As a fat-soluble vitamin, vitamin E (VE) is prone to suboptimal intake in the general population. Alpha-tocopherol (α-TE) represents the most biologically significant form of VE in vivo. Nevertheless, the potential detrimental effects of α-TE deficiency on health remain unclear. This study was conducted to investigate the effect of α-TE deficiency on hepatic metabolism and gut microbiota. Methods C57BL/6J mice were randomly assigned to receive one of three dietary regimens: a α-TE-deficient diet, a control diet with normal α-TE, or a high-dose diet containing four times the normal α-TE level. Histopathology, serum biochemistry, RNA-Seq, RT-qPCR, Western blot, and 16S rRNA gene sequencing with correlation analysis were used to assess metabolic phenotypes, hepatic circadian, hepatic lipid metabolism, and cecal microbiota, respectively. Results The results demonstrated that α-TE deficiency induced hepatic steatosis and lipid metabolic disturbances. α-TE deficiency significantly decreased Arntl and Clock expression, but increased Per2. Additionally, it upregulated the expression of lipogenic genes such as Scd1, Elovl6, and Elovl3 and simultaneously downregulated fatty acid oxidation genes such as Cyp4a10, Cyp4a14, and Acot1, bringing about imbalance in lipid homeostasis. In addition, α-TE deficiency greatly changed the structure and composition of gut microbiota. Bacterial genera like Alistipes, norank_f__Muribaculaceae, Muribaculum, Odoribacter, and Dubosiella were significantly correlated with hepatic circadian and lipid metabolism gene expression with the strongest correlation being Alistipes. Conclusions This work is the first to reveal that short term α-TE deficiency could cause lipid metabolic disorder via the \"gut microbiota-liver circadian clock\" axis, which provides novel insights into the etiology of nutrition-related metabolic diseases and targets for nutritional intervention.\n\nID: 42354872\nTitle: Oleanolic Acid Modulates the Gut-Liver Axis to Alleviate High-Fat Diet-Induced Hepatic Lipid Deposition in Nile Tilapia (Oreochromis niloticus).\nAbstract: This study examined the protective mechanisms of oleanolic acid (OA) against high-fat diet (HFD)-induced hepatic steatosis and intestinal dysbiosis in Nile tilapia. Fish were allocated to four groups: normal diet (ND), HFD, and OA-supplemented HFD (50 and 250 mg/kg). After 42 days, physiological, biochemical, and histological assessments demonstrated that OA markedly reduced hepatic lipid accumulation, mitochondrial injury, and intestinal shortening. Transcriptomic analysis revealed that OA alleviated lipid dysregulation by inhibiting de novo lipogenesis and promoting lipid trafficking and β-oxidation, effectively reversing HFD-induced changes in the PPAR, MAPK, mTOR, and autophagy-lysosome signaling pathways. 16S rRNA sequencing indicated that OA increased microbial alpha diversity, suppressing HFD-associated taxa (e.g., Nordella) while enriching beneficial genera such as Clavibacter, Bosea, and Bdellovibrio. Importantly, OA treatment restored HFD-induced depletion of intestinal butyric acid and suppressed hepatic pro-inflammatory cytokines (tnf-α, il-1β), while upregulating growth-related factors (igf1). Correlation analysis confirmed strong associations between microbial alterations (Nordella and Phreatobacter) and hepatic lipid metabolism and inflammatory gene expression. Overall, OA mitigates metabolic stress in Nile tilapia by reconfiguring the gut-liver axis, integrating microbial restoration with precise regulation of hepatic nutrient-sensing and inflammatory pathways, providing a potential therapeutic strategy for lipid metabolism disorders in aquaculture.\n\nID: 42353191\nTitle: Akkermansia muciniphila Alleviates Enterococcus faecalis-Exacerbated Alcoholic Liver Injury by Modulating Gut Microbiota and Barrier Function.\nAbstract: Cytolysin-positive Enterococcus faecalis is a key pathogen in severe alcoholic hepatitis, yet the mechanisms through which it worsens disease and possible therapeutic strategies remain poorly understood. This study aimed to clarify the pathogenic effects of E. faecalis in acute alcohol-associated liver disease (ALD) and to assess the protective potential of Akkermansia muciniphila (Akk11) against this pathogen. Using a mouse model of acute ethanol gavage, animals received E. faecalis and/or Akk11 under prophylactic or therapeutic regimens. Assessments included liver injury markers, histopathology, lipid profiles, inflammatory cytokines, gut barrier integrity, and gut microbiota composition. E. faecalis exacerbated ethanol-induced hepatic steatosis and injury, showing a paradoxical effect: it increased histological damage while lowering circulating LPS and transaminases. This was linked to upregulated hepatic autophagy (increased Atg7) and reduced cholesterol, yet it promoted neutral lipid accumulation. Importantly, E. faecalis aggravated gut dysbiosis by markedly enriching the pro-inflammatory pathobiont Helicobacter typhlonius and impairing colonic barrier function. Intervention with Akk11 alleviated liver injury, reduced lipid accumulation and oxidative stress, and restored cytokine balance. Akk11 also strengthened gut barrier integrity, lowered serum endotoxin, and beneficially reshaped the microbiota. Prophylactic administration was particularly effective, normalizing the Firmicutes/Bacteroidota ratio, suppressing H. typhlonius, and enriching beneficial Bacteroides sartorii. This study confirms the pathogenic role of E. faecalis in acute ALD and establishes A. muciniphila (Akk11) as a promising microbiota-targeted therapy, which protects against liver injury by reinforcing the gut barrier, selectively modulating microbiota, and reducing inflammation, with prophylactic administration showing superior efficacy.\n\nID: 42352033\nTitle: Probiotic Modulation of Gut Microbiota: Antioxidant Mechanisms and Clinical Benefits in Obesity and Type 2 Diabetes Management.\nAbstract: Obesity and type 2 diabetes mellitus (T2DM) represent intertwined global epidemics driven by gut dysbiosis, chronic inflammation, and impaired SCFA production, identifying the microbiome as a therapeutic target. This review synthesizes mechanistic insights and clinical evidence on the role of probiotics as microbiome modulators in the management of metabolic disease. A comprehensive literature search across PubMed, Scopus, Web of Science, and Google Scholar up to May 2026 identified ~230 records using keywords such as probiotics, SCFAs, obesity, and T2DM; a narrative synthesis integrated preclinical, RCT, and meta-analytic data without formal pooling due to heterogeneity. Probiotics restore eubiosis via strain-specific mechanisms, Lacticaseibacillus rhamnosus GG enhances tight junctions (ZO-1), Bifidobacterium breve BBr60 boosts butyrate cross-feeding, and pasteurized Akkermansia muciniphila remodels bile acids (FXR/FGF19), activating G-Protein Coupled Receptor 41 (GPR41)/43-GLP-1 signaling, Treg expansion, and NF-κB suppression. Beyond immunometabolic effects, probiotics mitigate obesity- and T2DM-related oxidative stress by upregulating endogenous antioxidant enzymes (e.g., SOD, catalase, GPx), modulating Nrf2/Keap1 signaling, and reducing lipid peroxidation and other oxidative stress markers in experimental and clinical settings. Meta-analyses of RCTs reveal modest benefits: BMI reductions (~0.3 kg m-2), waist circumference (WC) reductions (1-2 cm), HbA1c reductions (0.3-0.4%), and improvements in homeostatic model assessment of insulin resistance (HOMA-IR), especially with multi-strain (>109 CFU day-1, ≥12 weeks) synbiotics. Innovative strategies-synbiotics, postbiotics, AI-tailored consortia, and fermented dairy-address engraftment and response variability. Current guidelines recommend 109-1011 CFU day-1 using multi-strain formulations for 12-24 weeks alongside lifestyle measures, with regimen selection tailored to the dysbiosis phenotype (e.g., NAFLD). Future longitudinal RCTs integrating multi-omics endpoints with AI-driven strain selection should refine-and ultimately individualize-precision probiotic strategies for metabolic therapy.\n\nID: 42351716\nTitle: Lack of Galectin-3 Disturbs Gut-Adipose-Liver Axis in High-Fat-Diet Mice Model.\nAbstract: Background/Objectives: A high-fat diet (HFD) promotes hepatic steatosis, inflammation, and systemic metabolic imbalance. Notably, HFDs can affect the gut-liver axis and adipose tissue homeostasis. Galectin-3 (Gal-3) binds to β-galactosides and plays regulatory roles in the gut-liver axis, connecting metabolic stress with inflammation and tissue remodelling. The objective of this study was to investigate whether Gal-3 affects the gut-liver axis and adipose tissue biology after HFD supplementation. Methods: Six-week-old C57BL/6 mice were randomly divided into either wild-type (Lgals3+/+) or knockout (Lgals3-/-) groups. Both groups received an HFD orally for 12 weeks, along with their respective control groups. Physiological measurements and microscopic examination of the gut, liver, and fat tissue were conducted using optical microscopy. Results: The HFD induced obesity in Lgals3+/+ mice, but not in Lgals3-/- mice, which exhibited lower weight gain, food intake, daily energy intake, and energy efficiency than Lgals3+/+ mice. Moreover, Lgals3-/- HFD mice had hyperglycaemia and hyperinsulinemia. Histological analysis revealed hypertrophied adipose tissue in Lgals3+/+ HFD mice with abundant Gal-3+ crown-like structures, rarely observed in Lgals3-/- HFD mice. In the jejunum, Lgals3+/+ HFD mice showed a significant reduction in Gal-3 expression in intestinal epithelial cells, whereas inflammatory signals were increased in Lgals3-/- HFD mice. In the liver, Lgals3+/+ HFD mice showed significant steatosis and macrophages expressing Gal-3. In contrast, Lgals3-/- HFD mice showed pronounced hepatocyte ballooning, suggesting a more progressive stage of metabolic dysfunction-associated steatotic liver disease (MASLD). Conclusions: Together, these data suggest that Gal-3 protects the gut-liver axis and adipose tissue against cytotoxic effects caused by HFD.\n\nID: 42349743\nTitle: Maternal butyrate administration ameliorates fetal fatty liver and maternal metabolic alterations related to maternal obesity.\nAbstract: Obesity negatively impacts maternal and fetal metabolism, leading to the programming of metabolic disturbances in the offspring. We have previously reported numerous maternal, fetal and offspring alterations in a rat model of obesity. In this study, we administered butyrate-a short-chain fatty acid derived from gut microbiota metabolism-to obese mother rats during pregnancy and lactation in an attempt to improve maternal health and prevent the fetal features associated with the programming of fatty liver disease. The initial experimental study design comprised female Albino-Wistar rats assigned to either a control diet (C group) or a high-fat diet (FD group) to induce obesity, before being paired with control males. Pregnant rats received either butyrate (CB or FDB) or water as a vehicle (C or FD) during gestation and were euthanized at day 21 of pregnancy. The second experimental design comprised C, FD, and FDB rats that gave birth and breastfed their pups, with mothers being euthanized at the conclusion of the lactation period. At term gestation, rats with obesity exhibited increased adiposity, hepatic lipid accumulation, triglyceridemia, and circulating IL-1β. Their fetuses displayed increased body weight, liver lipid over-accumulation, and altered mRNA levels of genes involved in liver damage. Notably, butyrate administration decreased maternal circulating levels of triglycerides and IL-1β, and prevented fetal overweight status and hepatic lipid accumulation at term gestation. Importantly, butyrate exerted no effect on control rats or their fetuses. Moreover, butyrate administration ameliorated features of fatty liver disease in overweight rats at the end of lactation, further demonstrating its beneficial effects on both mothers and fetuses in this rat model of obesity.\n\nID: 42346379\nTitle: Nervonic Acid Prevents HFD-Induced Metabolic Dysfunction and Is Associated with Gut Microbiota Remodeling.\nAbstract: Obesity is closely associated with gut microbiota dysbiosis. Nervonic acid (NA; (15Z)-15-tetracosenoic acid) is a bioactive fatty acid with reported metabolic effects. This study aimed to investigate the associations between NA administration, gut microbiota composition changes, and host metabolic phenotypes in high-fat diet (HFD)-fed mice. C57BL/6J mice were fed an HFD for 12 weeks and concurrently administered NA at doses of 20, 40, and 60 mg/(kg·d) by gavage. Metabolic parameters, histopathological changes, and fecal microbiota composition (via 16S rRNA gene sequencing) were evaluated. NA administration was associated with significantly attenuated HFD-induced increases in body weight and adipose tissue mass, as well as marked reductions in serum total cholesterol, triglycerides, and low-density lipoprotein cholesterol (all p < 0.05). Hepatic steatosis and adipose tissue inflammation were also attenuated. 16S rRNA gene sequencing revealed that NA was associated with the counteraction of HFD-induced gut microbiota dysbiosis, including alterations in α-diversity and community structure. NA was associated with higher relative abundances of taxa such as Blautia, Oscillibacter, Faecalibaculum, Parabacteroides, Dubosiella, and Odoribacter and lower relative abundances of Lachnoclostridium, Mucispirillum, and Alistipes. Within-group correlation analyses showed that genera with higher relative abundances were inversely associated with lipid parameters and adiposity, whereas genera with lower relative abundances correlated positively with these metabolic indicators. NA administration was associated with bidirectional changes in gut microbiota composition-the enrichment of certain taxa and the suppression of others-concomitant with the amelioration of HFD-induced metabolic dysfunction. These findings indicate correlations between NA, gut microbiota alterations, and improved metabolic phenotypes; however, causality remains to be established.\n\nID: 42346116\nTitle: The Gut-Brain-Immune Axis: Multi-Omics Insights into Neurodegenerative and Metabolic Diseases.\nAbstract: The axis linking the gut to the brain to the immune system connects all tissues involved-bacteria, immune cells, metabolism and the CNS-through a multidirectional communication network. Several studies have confirmed that when this axis is disrupted, it can be responsible for Alzheimer's disease, Parkinson's disease, obesity, type 2 diabetes, and NAFLD, and the main consequences come from increased systemic inflammation, altered regulation of immune cells, the production of microbial metabolites that alter signals to the immune cells and nervous system, increase in oxidative stress, breakdown of the gut barrier, and more. In recent years, advanced multi-omics technologies, such as metagenomics, transcriptomics, metabolomics, proteomics, and single-cell sequencing, have provided significant advancement in our understanding of all of the interacting nodes involved in the gut-brain-immune axis. These advanced sequencing technologies can characterize the microbial communities, host immune cells, metabolic profiles, and the degree of cell heterogeneity during a specific disease. Combining multi-omics information can reveal a few shared pathways between neurodegenerative and metabolic disorders, such as NF-κB, NLRP3 inflammasome activation, mitochondrial dysfunction, changes in SCFA metabolism, and the alteration of microbial populations in Alzheimer's and Parkinson's disease; metabolic dysbiosis and increased risk for Parkinson's disease; or changes in gut-to-brain-to-immune signaling contributing to diabetes complications and NAFLD. Artificial intelligence (AI) and machine learning are becoming promising tools for detecting biomarkers from these datasets, extracting knowledge, interpreting systems biology, and helping with developing precision medicine. In this review, we summarize current evidence that supports the role of the gut-brain-immune axis in neurodegenerative and metabolic diseases, highlighting results gained with the utilization of multi-omics approaches. We will describe the key microbial, immune, and metabolic pathways involved in pathogenesis and therapeutic approaches including psychobiotics, tailored nutrition, modulation of the microbiome, and metabolite interventions, discussing future perspectives of the translation of the gut-brain-immune axis knowledge into clinical practice.\n\nID: 42321612\nTitle: Adherence to the dietary index for gut microbiota and the 5-year incidence of metabolic dysfunction-associated steatotic liver disease in Iranian adults: a prospective cohort study.\nAbstract: Diet is a key modulator of gut microbiota and may influence the development of metabolic dysfunction-associated steatotic liver disease (MASLD). The Dietary Index for Gut Microbiota (DI-GM) has been proposed to capture the overall capacity of diet to promote a favorable gut microbial profile. Prospective evidence linking DI-GM to MASLD risk remains limited. This prospective analysis included 5,058 adults without MASLD at baseline from the Monitoring of Metabolic Diseases Risk Factors in Tehran (MMRT) study. Dietary intake was assessed using a validated 125-item food frequency questionnaire. The five-year incidence of MASLD was evaluated using multivariable logistic regression models, and associations were expressed as odds ratios (ORs) with 95% confidence intervals (CIs). Subgroup analyses were conducted to assess potential effect modification. Sensitivity analyses examined the robustness of results after excluding participants with substantial weight gain and after additional adjustment for metabolic and dietary factors. Mediation analyses were performed to explore potential pathways underlying the observed associations. Over five years of follow-up, 562 participants developed MASLD. Higher DI-GM scores were associated with a lower likelihood of incident MASLD. In the fully adjusted model, individuals in the highest quartile of DI-GM had 42% lower odds of MASLD compared with those in the lowest quartile (OR:0.58; 95%CI:0.42-0.80; P-trend < 0.01). Each one-standard-deviation increment in DI-GM score was associated with reduced odds of MASLD (OR:0.72; 95%CI:0.65-0.81;P-value < 0.001). The inverse association was more pronounced among women and participants aged ≥ 45 years (P-interaction < 0.01). Mediation analyses suggested that CAP, HOMA-IR, and serum vitamin D partially explained the association. Greater adherence to a diet supportive of gut microbiota, as reflected by higher DI-GM scores, was associated with a lower five-year risk of MASLD. These findings highlight the potential role of microbiota-related dietary patterns in MASLD prevention.\n\nID: 42421964\nTitle: SARS-CoV-2-infected adipocytes drive adipose inflammation and hepatocyte lipid accumulation.\nAbstract: Obesity and fatty liver may worsen COVID-19 outcomes, but the mechanism by which adipose tissue infection contributes to liver injury is unclear. We aimed to determine whether SARS-CoV-2 infection of human adipocytes promotes inflammation and hepatic lipid accumulation, and to identify the underlying mechanisms. Mesenchymal stem cell-derived human adipocytes were infected with Wuhan SARS-CoV-2 strain. Cell-surface ACE2 expression was measured in adipocytes. Viral replication and infectious titers were measured, and adipocyte morphology, cytokine/adipokine secretion, and lipid metabolism gene expression were analyzed. Culture supernatants from infected adipocytes were then applied to Huh7.5 hepatocytes to evaluate steatosis and fibrogenic activation. SARS-CoV-2 productively infected adipocytes, which express cell-surface ACE2, leading to hypertrophy, increased IL-6 secretion, a higher leptin/adiponectin ratio, and lipid droplet accumulation. The infectious virus was released into the supernatants. However, neutralization with anti-Spike antibodies or UV-C inactivation abolished this effect, indicating that hepatocyte lipid accumulation depended on infectious virus rather than on soluble adipocyte-derived mediators alone. Adipose tissue can serve as a source of infectious SARS-CoV-2 that promotes hepatic steatosis and fibrogenic activation, suggesting a mechanism by which obesity and fatty liver may worsen COVID-19 outcomes, although the contribution of residual infectious virus versus adipocyte-derived factors cannot be fully distinguished. At present, the data do not support an independent role for adipocyte-derived soluble mediators in this effect. The study is intended as a mechanistic in vitro analysis of adipocyte-hepatocyte crosstalk during SARS-CoV-2 infection.\n\nID: 42406801\nTitle: MicroRNA In Metabolism-Related Fatty Liver Inflammation: Mechanisms and Clinical Translation Prospects.\nAbstract: Metabolic-associated steatohepatitis (MASH) represents a growing global public health challenge. Its complex pathogenesis involves multiple pathological pathways, including lipid metabolism, inflammation, and fibrosis, yet effective specific diagnostic and therapeutic approaches remain elusive. MicroRNAs (miRNAs), as key post-transcriptional regulators, play an important role in the development and progression of MASH. This narrative review examines the molecular mechanisms by which miRNAs regulate lipid accumulation, inflammatory activation, hepatocyte injury, and fibrosis in MASH, while exploring their potential as non-invasive biomarkers for diagnosis and prognosis assessment. Additionally, the article focuses on analyzing the progress of preclinical research and the translational challenges of targeted therapeutic strategies based on miRNA mimics and antagonists, including delivery issues, off-target effects, reproducibility, and long-term safety. Despite encouraging preclinical evidence, major hurdles remain in clinical translation, including the lack of standardized protocols, efficient liver-specific delivery systems, and comprehensive safety data. Addressing these limitations may enable miRNA-based diagnostics and therapeutics to become precision tools for MASH management, though further validation through large-scale prospective studies is required.\n\nID: 42404519\nTitle: Protein-losing enteropathy after the Fontan procedure - A cardiologist's and gastroenterologist's perspective.\nAbstract: Protein-losing enteropathy (PLE) is a severe, multifactorial complication of Fontan circulation that affects approximately 12% of patients with single-ventricle physiology. Because no universal standard therapy exists, management is individualized and guided by the dominant hemodynamic and lymphatic drivers, clinical severity, and local expertise. Chronically elevated central venous pressure and impaired lymphatic drainage promote lymph congestion and leakage into the intestinal lumen, leading to hypoalbuminemia, edema, diarrhea, malnutrition, and immune dysfunction. Treatment is multimodal and includes optimization of Fontan hemodynamics, symptomatic and anti-inflammatory pharmacotherapy, and targeted nutritional strategies (high-protein diet, medium-chain triglycerides, and supplementation). Advances in lymphatic imaging have enabled phenotype-based, lymphatic-directed interventions such as lymphatic embolization and thoracic duct decompression, which can improve outcomes in selected patients. When conservative and interventional strategies fail, heart transplantation remains the definitive option. Emerging evidence also highlights the potential contribution of the gut-liver axis, including intestinal barrier dysfunction and alterations in the microbiome, which may influence inflammation and disease persistence. This review summarizes current concepts in PLE pathophysiology and therapeutic approaches, with emphasis on lymphatic dysfunction and evolving adjunctive targets.\n\nID: 42388647\nTitle: Astaxanthin Vesicles Improve Alcoholic Liver Disease Through Oxidative Stress and NF-κB Inflammatory Pathway.\nAbstract: Liver injury induced by alcoholic fatty liver disease (ALD) will eventually lead to the development of hepatocellular carcinoma. The antioxidant and anti-inflammatory functions of astaxanthin (AST) can prevent and alleviate liver injury. In this study, AST was embedded in fatty acid vesicles to determine the effects of astaxanthin vesicles (AST-FAV) on ALD. The results demonstrated that compared to free AST, AST-FAV improved liver fat accumulation and oxidative damage caused by excessive drinking, and inhibited the production of pro-inflammatory cytokines by regulating the TLRs/MyD88/NF-κB, TNF-α/TNFR/NF-κB, and NLRP3/NF-κB pathways. In summary, AST-FAV can exert its anti-inflammatory effect through antioxidation and multiple pathways to prevent liver injury. These findings not only highlight the potential of AST-FAV for application in functional foods or dietary supplements but also provide a theoretical basis for further exploration of its potential as a clinical intervention strategy for the prevention or adjunctive treatment of alcoholic liver disease in humans.\n\nID: 42374202\nTitle: Bioactive folate attenuates valproic acid-induced NAFLD in female rats.\nAbstract: Nonalcoholic fatty liver disease (NAFLD) is a key contributor to chronic liver diseases. It is defined as hepatic fat accumulation in ≥ 5% of hepatocytes in individuals with minimal or no alcohol consumption and no other identifiable causes of liver steatosis. Drug-induced hepatic toxicity is increasingly recognized as a key contributor to the development and progression of NAFLD. Among them, valproic acid (VPA), an antiepileptic drug, is well documented for inducing hepatic steatosis, in addition to interfering with folate metabolism and accelerating the progression of NAFLD. The current study distinctively evaluates the protective role of bioactive folate derivatives (folinic acid and 5-methyltetrahydrofolate) in a VPA-induced NAFLD rat model. Adult female Sprague Dawley rats were divided into three groups: control, diseased and treated. Liver function test, histopathological examination, gene expression analysis, and molecular docking were performed. Liver function tests indicated that the increase in alanine aminotransferase, alkaline phosphatase, and total bilirubin levels was highly significant in the diseased group, indicative of hepatic injury. Histopathological examination demonstrated severe steatosis in VPA-treated animals, which was significantly improved in the folate-treated group. The NAFLD Activity Score, a mild NAFLD was observed in the diseased group with a total score of 2. Gene expression studies showed high upregulation of HO-1 and pro-inflammatory cytokines TNF-α and IL-6 in the diseased group, whereas downregulation was observed in folate-treated rats. Furthermore, molecular docking studies indicated that folinic acid and 5mTHF showed high affinities for binding to KEAP1 protein, suggestive of activation of the Nrf2-KEAP1 antioxidant pathway. Collectively, our data provide significant evidence for the protective potential of bioactive folate supplementation in the amelioration of the VPA-induced liver injury through modulation of oxidative stress, inflammation, and lipid accumulation.\n\nID: 42359071\nTitle: Chemoprophylaxis effect of EGCG on various digestive system diseases: a systematic review and meta-analysis.\nAbstract: Epigallocatechin-3-gallate (EGCG) constitutes the main component of tea polyphenols found in tea leaves and has been found to have a positive therapeutic effect on various digestive system diseases. However, no systematic review has been conducted on the research progress and mechanisms of EGCG in relation to digestive system diseases, an its toxicity. We conducted a comprehensive literature search for preclinical studies from the inception of each database to 28th September 2025, including Embase, PubMed, Web of Science, China National Knowledge Infrastructure and Veipu Information. These studies were manually screened based on predefined criteria. A comprehensive literature review and meta-analysis were then performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A total of 74 animal studies were initially included. Following screening, 63 studies (involving 738 animals) met the inclusion criteria for the meta-analysis. EGCG's animal experiments in digestive system diseases primarily focus on tongue squamous cancer, colorectal cancer, liver cancer, ulcerative colitis, gastric cancer, and functional gastrointestinal disorders. EGCG also has positive effects on pancreatic cancer, radiation enteritis, hepatitis B, oral cancer, esophageal cancer, radiation-induced esophagitis, hepatitis C, acute pancreatitis, fatty liver, and cancer prevention. The potential common pathways include VEGF, EGFR, Notch, Bax/Caspase, Nrf2/UGTIA10, JAK/STAT, NF-κB, IGF/IGF-IR, Caspase-1, HIF-1α/VEGF, TGFβ/p-ERK/p-Smad1/2 and M1/M2 cell polarization. EGCG suppresses cell proliferation through the induction of apoptosis; however, its underlying mechanisms warrant further investigation. Administration of high-dose EGCG alone can induce hepatotoxicity, an effect that is exacerbated under inflammatory conditions. In the context of diabetes, EGCG may also lead to nephrotoxicity. It should be noted that these toxic doses substantially exceed the levels typically attained through normal dietary consumption of tea. The mechanisms responsible for EGCG-mediated toxicity remain to be fully elucidated. In vivo studies have indicated the potential efficacy of EGCG in managing gastrointestinal diseases. However, further investigations are necessary to validate its therapeutic benefits, elucidate the underlying mechanisms, and assess its potential toxicity.\n\nID: 42354127\nTitle: Flavonoids as Nutraceuticals to Treat Inflammatory Diseases: Focusing on Quercetin, Kaempferol, Luteolin, Apigenin, Epicatechin and Their Effects on Hepatic, Nervous, and Pulmonary Systems.\nAbstract: The immune response is essential in the protection of our body against pathogens; however, the inflammatory response caused by the immune system can become a disease itself. In fact, anti-inflammatory and immune-suppressive drugs are applied to limit the immune response to treat inflammatory diseases. Flavonoids are plant-derived polyphenols extensively investigated for their anti-inflammatory and antioxidant properties in inflammatory diseases. Studies applying isolated compounds as well as using supplements as nutraceuticals based on flavonoids have been conducted. Our review systematically analyzed the top five studied flavonoids between 2020 and 2025: quercetin (1742 articles), kaempferol (642), luteolin (589), apigenin (419), and epicatechin (354), highlighting their major therapeutic applications in diseases affecting the liver (12%), nervous system (11%), and lungs (10%). Mechanistically, these compounds act as multi-target agents mainly by inhibiting NF-κB and inducing Nrf2-dependent antioxidant programs. Application of advanced delivery systems, which increase oral bioavailability by up to 20-fold, overcomes pharmacokinetic bottlenecks. Clinical highlights demonstrated promising therapeutic effects, including reduced intrahepatic lipid accumulation in non-alcoholic fatty liver disease patients following quercetin supplementation (11.5% to 9.6%) and accelerated SARS-CoV-2 clearance after quercetin phytosome administration. The translation of flavonoids into standardized clinical therapies remains limited by the lack of large-scale, well-controlled clinical trials.\n\nID: 42353596\nTitle: Niemann-Pick C1-Like 1 in Cholesterol Absorption and Homeostasis: Mechanisms, Regulation, and Emerging Phytochemical Inhibitors.\nAbstract: Disruption of cholesterol homeostasis is closely associated with hypercholesterolemia, dyslipidemia, atherosclerotic cardiovascular disease (ASCVD), and metabolic disorders such as metabolic dysfunction-associated fatty liver disease (MAFLD). Intestinal and hepatic cholesterol absorption are central to maintaining systemic cholesterol balance, with Niemann-Pick C1-Like 1 (NPC1L1) acting as a key transporter that mediates cholesterol uptake in enterocytes and hepatocytes. Aberrant NPC1L1 expression or activity promotes excessive cholesterol accumulation in both plasma and liver, thereby contributing to dyslipidemia and hepatic steatosis. Consequently, NPC1L1 has emerged as an important therapeutic target for reducing cholesterol absorption and improving lipid homeostasis. Although ezetimibe is currently the only clinically approved NPC1L1 inhibitor, its limited efficacy as monotherapy highlights the need for alternative or complementary therapeutic strategies. Growing evidence indicates that natural phytochemicals, particularly polyphenols and flavonoids, can modulate NPC1L1 at both transcriptional and functional levels. These compounds not only suppress intestinal cholesterol absorption but also attenuate hepatic lipid accumulation, ultimately improving circulating lipid profiles. This review summarizes recent advances in understanding the role of NPC1L1 in cholesterol metabolism and highlights the emerging therapeutic potential of phytochemicals as novel complementary approaches for the prevention and treatment of lipid metabolic disorders.\n\nID: 42352893\nTitle: Impact of Air Pollution on Metabolic Dysfunction-Associated Fatty Liver Disease.\nAbstract: Metabolic dysfunction-associated fatty liver disease (MAFLD) is now recognized as a leading form of chronic liver disease globally and is strongly associated with metabolic abnormalities. Traditionally, the pathogenesis of MAFLD has mainly been attributed to genetic susceptibility and unhealthy lifestyles (such as high-calorie diets and sedentary behavior). However, in recent years, environmental factors, especially air pollution, have been confirmed as independent risk factors and important promoting factors for MAFLD development and further disease progression. This review summarizes current epidemiological findings on the link between air pollution exposure and MAFLD, while exploring its potential biological mechanisms involving systemic inflammation, oxidative stress, immune alteration, genetic risk, and epigenetic regulation underlying the relationship between air pollution and hepatic steatosis. It also reviews the additive interaction between air pollution and lifestyle or socioeconomic factors in MAFLD. Finally, we also discuss multilevel strategies spanning individual-, community-, national-, and global-level cooperation to address the increasing public health burden caused by air pollution. Therefore, incorporating the assessment and control of air pollution into the comprehensive strategies for MAFLD prevention and treatment has important scientific value and public health significance.\n\nID: 42351370\nTitle: Pomegranate seed oil attenuates palmitic acid-induced hepatic injury through modulation of oxidative stress: insights from GC-Q-TOF-MS-based metabolomics.\nAbstract: Non-alcoholic fatty liver disease (NAFLD) is a leading cause of chronic liver disease worldwide, with oxidative stress and lipid dysregulation as central pathogenic drivers. Pomegranate seed oil (PSO), rich in the conjugated fatty acid punicic acid, has demonstrated potential antioxidant and lipid-modulating properties, yet its hepatoprotective mechanisms remain incompletely characterized at the metabolic level. Gas chromatographic-mass spectrometric analysis of the fatty acid composition of supercritical CO2-extracted PSO revealed that punicic acid was the predominant fatty acid, comprising 74.47% of the total identified fatty acids, which collectively accounted for approximately 95% of the fatty acid profile. In palmitic acid (PA)-challenged C57BL/6 mice, PA administration significantly increased serum and hepatic lipid levels, liver function markers, oxidative stress indicators, and inflammatory cytokines. PSO intervention dose-dependently ameliorated several of these abnormalities and markedly reduced hepatic lipid accumulation. Gas chromatography-quadrupole time-of-flight mass spectrometry-based serum metabolomics revealed that PSO markedly reversed PA-induced metabolic disturbances, identifying 27 key differential metabolites predominantly associated with amino acid and lipid metabolism. Pathway enrichment analysis highlighted oxidative stress-related pathways, including glutamate, taurine, and fatty acid metabolism. PSO significantly upregulated antioxidant metabolites (cysteine, glutamate, hypotaurine, α-tocopherol) while downregulating oxidative markers (uric acid, xanthine). Complementary in vitro experiments in PA-treated L02 human hepatocytes further demonstrated that PSO alleviated lipotoxicity by attenuating reactive oxygen species generation and preserving membrane integrity. These findings demonstrate that PSO exerts hepatoprotective effects through multi-target, multi-pathway synergistic mechanisms, particularly via enhancing endogenous antioxidant defense systems, providing scientific evidence for PSO as a promising nutritional intervention strategy for NAFLD prevention and treatment. © 2026 Society of Chemical Industry.\n\nID: 42339503\nTitle: The correlation between periodontitis and fatty liver and the improvement of NAFLD by periodontal treatment.\nAbstract: Emerging evidence highlights a pathophysiological interplay between periodontitis and non-alcoholic fatty liver disease yet the mechanistic underpinnings and therapeutic implications remain contentious. This review systematically elucidates molecular crosstalk through the \"oral-gut-liver axis\" and \"oral-liver axis\". A comprehensive literature review was conducted using PubMed, Scopus and Web of Science, employing keywords related to periodontal disease and non-alcoholic fatty liver disease. Analysis of 16 original studies revealed that periodontitis and its associated pathogens promote the progression of non-alcoholic fatty liver disease through multiple pathways: (1) activation of hepatic inflammatory responses (elevated IL-6, IL-17, and TNF-α levels), (2) exacerbation of metabolic dysregulation (increased HOMA-IR, ALT, and AST), and (3) disruption of the oral-gut-liver axis. Notably, non-surgical periodontal therapy demonstrated therapeutic potential by simultaneously improving periodontal health and attenuating non-alcoholic fatty liver disease progression through reduction of hepatic pro-inflammatory cytokines and fibrogenic mediators. Periodontitis may exacerbate systemic inflammation via the oral-liver and oral-gut-liver axes, inducing insulin resistance and promoting non-alcoholic fatty liver disease. Non-surgical periodontal therapy can improve non-alcoholic fatty liver disease, but methodological heterogeneity in current studies necessitates further prospective research to clarify their relationship.\n\nID: 42332507\nTitle: Therapeutic effects and mechanisms of Artemisia species on metabolic diseases: A systematic review.\nAbstract: The prevalence of metabolic disorders has increased significantly in recent years, driving interest in effective herbal remedies. Artemisia species, part of the Compositae family, encompass over 500 plants worldwide and have shown promising potential in addressing metabolic ailments. This review delineates the intricate chemical composition of Artemisia plants while offering a thorough summary of the pharmacological advancements and clinical evidence of Artemisia species in mitigating conditions such as diabetes, hyperlipidemia, nonalcoholic fatty liver disease, obesity, and gout. A systematic review was conducted following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. PubMed, Google Scholar, and Science Direct were searched up to December 2025. Studies evaluating Artemisia species for metabolic diseases (diabetes, hyperlipidemia, nonalcoholic fatty liver disease, obesity, or gout) were included. The included studies were analyzed and compared in terms of research types (animal, human, and in vitro studies), therapeutic outcomes, and mechanistic pathways. A qualitative synthesis was performed. Numerous experiments have demonstrated the efficacy of 28 Artemisia species in lowering blood sugar and lipid levels, stimulating insulin secretion, ameliorating insulin resistance, suppressing inflammation and oxidative stress, reducing fat synthesis, and modulating the gut microbiota. These findings underscore their potential as promising therapeutic candidates for the management of metabolic disorders. This review acts as a crucial guide for steering the progress of drug development and the therapeutic use of Artemisia plants in addressing metabolic diseases. However, clinical investigations into the effects of Artemisia on metabolic disorders in humans are still limited. Further trials are essential to validate its effectiveness in treating these ailments.\n\nID: 42300918\nTitle: The hawthorn (Crataegus pinnatifida) procyanidin extract attenuates nonalcoholic fatty liver disease in mice via remodeling the bile acid profile driven by gut microbiota and regulating the FXR pathway.\nAbstract: Hawthorn procyanidin extract (HPC) is one of natural plant-derived polyphenols with lipid-lowering and liver-protective properties, while its therapeutic mechanisms against nonalcoholic fatty liver disease (NAFLD) require further clarification. A high-fat diet (HFD)-induced NAFLD mouse model and oleic acid (OA)-induced HepG2 cells were utilized to conduct this study. We first found that HPC intervention ameliorated lipid accumulation in HepG2 cells, which was confirmed to depend on FXR signaling using an FXR inhibitior. In addition, HPC significantly relieved NAFLD in vivo by lowering the levels of TC, TG, and LDL-C and preventing the excessive accumulation of lipid droplets and hepatic steatosis. Besides, HPC intervention restored BA homeostasis (in the liver and gut) by markedly altering the profiles of primary versus secondary and conjugated versus unconjugated BAs (ωMCA, TαMCA, TβMCA, and DCA), which was related to the restoration of the HFD-induced dysbiosis. Mechanistically, HPC downregulated the expression of lipid synthesis protein SREBP1 by activating the hepatic FXR and CYP7A1 expressions, attributed to the controlling of the enterohepatic circulation mediated by the FXR-FGF15 pathway. Taken together, these findings substantiate that HPC exerts its ameliorative effect on NAFLD by modulating BA metabolism in NAFLD mice.\n\nID: 42294883\nTitle: Astragalus polysaccharides ameliorate perinatal metabolic syndrome in sows via enhancing butyrate-producing bacteria.\nAbstract: Astragalus polysaccharide (APS), a bioactive phytomacromolecule from Astragalus membranaceus, exhibits anti-inflammatory, antioxidant, and immunomodulatory activities. Given mammals' lack of endogenous glycosidases for APS catabolism, this study hypothesizes its bioactivity stems from gut microbial interactions, investigating APS-mediated microbiome remodeling and therapeutic effects on perinatal metabolic syndrome (PeriMS) in sows. In vitro fermentation showed that APS significantly increased short-chain fatty acid (SCFA) production, with acetate (44.51 mmol/L), propionate (17.37 mmol/L), and butyrate (22.04 mmol/L) levels notably elevated and enriched canonical butyrate-producing taxa (g_norank_f_Muribaculaceae, g_Monoglobus, g_unclassified_f_Lachnospiraceae, P < 0.05). In vivo, gestational APS supplementation (from day 90) improved piglet weaning weight, reduced maternal backfat loss during lactation, shortened post-weaning estrus interval, elevated intestinal butyrate, alleviated systemic inflammation/oxidative stress, and mitigated PeriMS. Mechanistic analysis associated PeriMS improvement with butyrate-producing bacteria, with butyrate playing a key role in gut health enhancement. These findings establish APS as a prebiotic, highlighting the gut microbiota-SCFA axis as a therapeutic target for PeriMS. This study provides targeted mechanistic evidence that the gut microbiota-SCFA axis mediates PeriMS improvement by APS. Mechanistic analysis linked PeriMS improvement to butyrate-producing bacteria, with butyrate playing a key role in gut health enhancement, which was verified by a sodium butyrate rescue experiment. These findings establish APS as a prebiotic, highlighting the gut microbiota-SCFA axis as a therapeutic target for PeriMS. This work provides novel evidence for microbiota-SCFA axis involvement in sow perinatal metabolic health, offering translational strategies to improve livestock metabolic health through APS supplementation. In intensive pig farming, 40% of multiparous sows develop perinatal metabolic syndrome (PeriMS) around farrowing, causing $150-$200 annual loss per sow due to inflammation (e.g., higher IL-6), oxidative stress, and extended weaning-to-estrus intervals (2.1 days). Gut dysfunction-marked by fewer butyrate-producing bacteria and increased endotoxin-triggers barrier damage and inflammation. Supplementing with Astragalus polysaccharides (APS, 10 g/day) enhances beneficial bacteria like Muribaculaceae and butyrogenic Bacteroides, raising butyrate in vitro. In sows, APS lowers endotoxemia and gut inflammation (calprotectin), correlating with reduced postpartum IL-6 and reactive oxygen species. It also improves productivity: less backfat loss and heavier weaned piglets. By targeting gut-barrier crosstalk, APS breaks the inflammation-metabolism cycle, providing a sustainable alternative to antibiotics to enhance peripartum sow health and profitability.\n\nID: 42290856\nTitle: Quantifying the metabolic-inflammatory axis: synergistic value of TyG index and FAI in assessing CAD risk among MAFLD patients.\nAbstract: This study evaluated coronary inflammation and insulin resistance (IR) using pericoronary fat attenuation index (FAI) and triglyceride-glucose (TyG) index, and assessed their associations with coronary heart disease (CHD) and functional ischemia in patients with metabolic dysfunction-associated fatty liver disease (MAFLD). A total of 435 patients (174 MAFLD, 261 MAFLD+CHD) were included. The MAFLD+CHD group was stratified by CT-derived fractional flow reserve (CT-FFR) into >0.80 and ≤0.80 subgroups. FAI and CT-FFR were automatically calculated using AI-based software; Independent risk factors were identified using multivariable logistic regression analysis, based on which a nomogram was constructed. The predictive performance of the nomogram was evaluated using ROC curves, calibration curves, and decision curve analysis (DCA), with internal validation performed via the Bootstrap method. The predictive accuracy of the nomogram was also compared with that of FAI and the TyG index. Restricted cubic spline (RCS) models were employed to explore the potential nonlinear relationship between the TyG index and FAI, as well as the dose-response associations of these indices with disease risk. Multivariate logistic regression showed that TyG index and FAI were independent risk factors for CHD and coronary functional ischemia (P<0.05), with CHD prevalence, functional ischemia, and TyG levels increasing alongside FAI. In MAFLD patients, the nomogram demonstrated excellent discrimination (ROC-AUC 0.952, 95% CI 0.935-0.970), and DCA, clinical net reduction, and clinical impact analyses confirmed its substantial clinical value in identifying high-risk CHD patients. For MAFLD patients with CHD, the nomogram also effectively predicted coronary functional ischemia (AUC 0.904, 95% CI 0.869-0.939). While FAI and TyG, alone or combined, had predictive value, the nomogram outperformed all single and combined indicators (AUCs 0.952 and 0.904; P<0.001). RCS analysis revealed a linear positive correlation be-tween TyG and FAI, both positively associated with CHD and functional ischemia risk. In patients with MAFLD and those with concomitant CHD, FAI was significantly positively correlated with the TyG index, and both were associated with the occurrence of CHD and coronary functional ischemia, suggesting that systemic metabolic dysfunction may promote disease progression through local coronary inflammation. Furthermore, a nomogram integrating the TyG index, FAI, and key clinical variables demonstrated excellent discriminative ability in internal validation, providing incremental diagnostic value for early CHD risk stratification in MAFLD patients.\n\nID: 42278341\nTitle: Aspirin Eugenol Ester Ameliorates Fatty Liver Hemorrhagic Syndrome in Laying Hens by Reducing Oxidative Stress and Inflammation.\nAbstract: Fatty liver hemorrhagic syndrome (FLHS) is a common metabolic disorder in laying hens, leading to reduced egg production and economic losses. Aspirin eugenol ester (AEE) has lipid-lowering, anti-inflammatory, and antioxidant properties, but its effects on FLHS are unknown. This study evaluated the protective effects of AEE using an in vivo FLHS model induced by a high-energy low-protein diet in laying hens and an in vitro steatosis model established by free fatty acid treatment in LMH cells. AEE alleviated liver histopathological damage, reduced oxidative stress (decreased ROS and MDA; increased SOD, GSH, and CAT), and suppressed inflammatory responses. The hepatoprotective effects of AEE were tentatively associated with altered molecular expression of the Nrf2 antioxidant pathway and MAPK/NF-κB inflammatory signaling; however, this correlation was speculated based on molecular detection and incomplete in vitro pharmacological interventions, lacking rigorous causal validation. These findings suggest that AEE alleviates FLHS-related liver injury in laying hens, possibly in association with altered oxidative and inflammatory status. Collectively, these preliminary findings provide a limited theoretical reference for the potential application of AEE as a preventive agent against FLHS in laying hens.\n\nID: 42278231\nTitle: Cyanidin-3-O-Glucoside Alleviates Hepatic Steatosis and Inflammation in High-Fat Diet-Induced Non-Alcoholic Fatty Liver Disease Mice via the AMPK/SIRT1/NF-κB Pathway.\nAbstract: Cyanidin-3-O-Glucoside (C3G) is the primary anthocyanin-active component in bilberry, exhibiting various pharmacological activities such as antioxidant, anti-inflammatory, and lipid metabolism-regulating effects. To address the clinical need for non-alcoholic fatty liver disease (NAFLD) prevention and treatment, this study aimed to investigate the ameliorative effects of C3G on NAFLD pathology and elucidate its molecular mechanisms of protection via the AMPK pathway. After a one-week acclimatization period, 20 six-week-old SPF mice were randomly divided into four groups: normal diet control (NCD), high-fat diet model (HFD), HFD + L-C3G (100 mg/kg/day), and HFD + H-C3G (200 mg/kg/day). Except for the NCD group, the remaining groups were fed a 60% high-fat diet for four weeks to establish an early-stage NAFLD model, with successful model construction verified by weight and liver weight gain. From the fifth week onward, C3G groups received daily administration for four consecutive weeks, while control groups were given an equal volume of distilled water. Liver function, lipid metabolism, oxidative stress, and inflammatory levels were assessed using ELISA, H&E staining, and other methods. The results showed that C3G restored liver function in NAFLD mice, improved lipid metabolism disorders, reduced oxidative stress and inflammatory responses, and alleviated liver pathological damage. Mechanistic studies revealed that C3G regulated the expression of mRNA and proteins related to the AMPK/SIRT1/NF-κB signaling pathway, activating the pathway by upregulating AMPK and its upstream regulators while inhibiting NF-κB-mediated inflammatory responses. This study confirmed that C3G can ameliorate high-fat diet-induced NAFLD lesions by activating the AMPK/SIRT1/NF-κB pathway, providing a potential intervention strategy for NAFLD prevention and treatment.\n\nID: 42277386\nTitle: Modulating the Gut-Liver Axis: Anti-Inflammatory Mechanisms of Probiotics and Prebiotics in MASLD.\nAbstract: Non-alcoholic fatty liver disease (NAFLD), recently reclassified as metabolic dysfunction-associated steatotic liver disease (MASLD), is a prevalent metabolic disorder with significant inflammatory underpinnings. Emerging evidence underscores the gut-liver axis as a pivotal pathway in MASLD pathogenesis through which dysbiosis drives cytokine-mediated inflammation, fibrosis, and disease progression. This review synthesizes preclinical and clinical findings on how probiotics and prebiotics modulate key inflammatory cytokines-including TNF-α, IL-6, IL-1β, IL-10, IL-17, and TGF-β-to ameliorate MASLD. The literature demonstrates that these interventions converge on the TLR4/NF-κB axis as the central mechanistic driver of cytokine dysregulation in MASLD. By restoring gut barrier integrity and reducing endotoxin (LPS) translocation, probiotics and prebiotics suppress TLR4/NF-κB activation, which secondarily inhibits the NLRP3 inflammasome (reducing IL-1β/IL-18), downregulates pro-inflammatory cytokines (TNF-α, IL-6, IL-17), and enhances anti-inflammatory signals (IL-10) through crosstalk with PPAR-α, AMPK, and Nrf2 pathways. In animal models, probiotic strains such as Bifidobacterium, Lactobacillus, and Akkermansia muciniphila consistently downregulate pro-inflammatory cytokines and enhance anti-inflammatory signals. The same is true for prebiotics, including inulin, oat β-glucan, and synbiotic formulations. However, clinical trial outcomes remain heterogeneous, influenced by strain specificity, intervention duration, and patient heterogeneity. Collectively, this review highlights the therapeutic potential of microbiota-targeted interventions to rebalance cytokine networks and proposes future directions for personalized, mechanism-driven approaches to the management of MASLD.\n\nID: 42276391\nTitle: Huanglian wendan decoction attenuates hepatic inflammation and lipogenesis via inhibition of the NF-κB/HDAC1/SREBP-1c axis.\nAbstract: Metabolic dysfunction-associated steatohepatitis (MASH) is characterized by hepatic steatosis accompanied by persistent inflammation and early fibrotic remodeling. In traditional Chinese medicine, Huanglian Wendan Decoction (HLWDD) is prescribed for phlegm-heat and damp-heat syndromes affecting the gallbladder and stomach and is traditionally used to clear heat, dry dampness, and resolve phlegm. It is commonly applied in the treatment of phlegm-heat-related metabolic disorders, including fatty liver disease. However, the therapeutic effects of HLWDD and the contributions of its key constituents to MASH remain to be further elucidated. This study aimed to evaluate the anti-inflammatory and lipid-regulatory effects of HLWDD and its key components in MASH and to explore the underlying molecular mechanisms. Male C57BL/6 J mice were given a methionine-choline-deficient (MCD) diet and received HLWDD in either low or high doses through oral gavage, with fenofibrate serving as a positive control. Body weight, liver index, serum levels of alanine aminotransferase and aspartate aminotransferase, serum lipid profiles, and hepatic triglyceride and total cholesterol contents were among the evaluated parameters. H&E, Oil Red O, and Masson's trichrome staining were used to evaluate histopathological changes. Hepatic macrophage infiltration was examined by immunofluorescence, inflammatory cytokines were measured by ELISA, and key signaling and lipid metabolism-related proteins were analyzed by western blotting. UPLC‒MS/MS was used to characterize the chemical profile of the HLWDD granules and identify their major constituents. Network pharmacology analysis integrating multiple databases, together with GO and KEGG enrichment analyses, was performed to predict potential targets and pathways. Molecular docking and molecular dynamics simulations were further used to investigate compound‒target interactions. Cell viability in vitro was measured with CCK-8 assays, protein levels were confirmed through western blotting, and intracellular lipid buildup was assessed using Oil Red O staining. UPLC‒MS/MS analysis revealed that berberine (BBR), an isoquinoline alkaloid, is a major bioactive component of HLWDD. Network pharmacology analysis suggested that HLWDD and BBR may exert anti-MASH effects by modulating multiple targets and pathways, including IL-6, PPARα, and the NF-κB/HDAC1/SREBP-1c axis. These predictions were supported by in vivo experiments, which confirmed the protective effects of HLWDD against MASH. Both in vivo and in vitro studies further revealed that BBR markedly ameliorated MASH-related phenotypes by suppressing the NF-κB/HDAC1/SREBP-1c axis. Additionally, simulations of molecular docking and dynamics revealed stable interactions between BBR and important proteins within this axis. Microscale thermophoresis (MST) assays further demonstrated direct binding of BBR to HDAC1. Collectively, these findings suggest that HLWDD and its key active constituent BBR alleviate MASH, at least in part, by inhibiting the NF-κB/HDAC1/SREBP-1c axis, which is closely associated with inflammatory responses and dysregulated lipogenesis. HLWDD markedly ameliorated the MASH phenotype by attenuating hepatic inflammation and lipogenesis, with the NF-κB/HDAC1/SREBP-1c axis emerging as a key mechanism linking inflammatory signaling to aberrant lipid synthesis. BBR, identified by UPLC‒MS/MS as a major active constituent of HLWDD, largely recapitulated these effects and directly bound to HDAC1, supporting its important contribution to the protective effects of HLWDD against MASH.\n\nID: 42272284\nTitle: Parthenolide ameliorates metabolic dysfunction-associated steatohepatitis by inhibiting M1 polarization by suppressing the nuclear factor-κB pathway.\nAbstract: Metabolic dysfunction-associated steatohepatitis (MASH) is an inflammatory disorder that results in ongoing liver inflammation and injury. During the course of hepatitis, parthenolide (PAR) promotes the recovery of liver function. Using a mouse model of MASH, the present study aimed to assess the effect of PAR on the condition. The MASH mouse model was developed using a high-fat diet combined with high-carbohydrate drinking, and measurements were taken for body weight, liver-to-body mass ratio, non-alcoholic fatty liver disease activity score, and levels of alanine aminotransferase and aspartate aminotransferase. Subsequently, liver injury was detected using hematoxyling and eosin staining, hepatic lipid accumulation was evaluated with oil red O staining, and liver fibrosis was assessed through Masson staining. Macrophage infiltration and M1 polarization were assessed by immunofluorescence staining for F4/80; and lipid metabolic, fibrotic, and pro-inflammatory indicators were detected by RT-qPCR; nuclear factor-κB (NF-κB) signaling pathway was assessed by Western blot. We found that PAR alleviated liver injury, improved lipid metabolism, and reduced fibrosis in MASH mice,. It also lowered macrophage infiltration in the liver, particularly decreasing M1 macrophages and pro-inflammatory cytokines. PAR inhibited the activation of the NF-κB pathway, and the protective effects were attenuated by an NF-κB pathway activators. We conclude that PAR ameliorates liver injury, hepatic lipid metabolism, fibrosis and inflammation in MASH mice, likely by suppressing the NF-κB pathway and thereby inhibiting M1 polarization.\n\nID: 42260857\nTitle: Exploring racial-specific associations between the food inflammation index(FII) and metabolic dysfunction-associated fatty liver disease (MAFLD) Prevalence: Data from the National Health and Nutrition Examination Survey 1999-2020.\nAbstract: The Food Inflammation Index (FII) is a novel indicator for assessing the impact of diet on systemic inflammation. Unlike the Dietary Inflammation Index, which focuses on nutrients, the FII quantifies specific foods, providing greater applicability to real-world dietary assessments. To date, no study has examined the association between FII and the prevalence of Metabolic dysfunction-associated fatty liver disease (MAFLD). This study aimed to investigate the relationship between FII and MAFLD. This cross-sectional study included 25,067 individuals aged ≥ 20 years from the 1999 to 2020 National Health and Nutrition Examination Survey (NHANES). Univariate and multivariate logistic regression analyses were performed to explore the relationship between FII and MAFLD. Nonlinear associations between FII and MAFLD were examined using restricted cubic spline (RCS) analysis. Subgroup analyses, interaction tests, and threshold effect analyses were conducted to assess differences across groups. The prevalence of MAFLD was 44.45%. FII was positively associated with MAFLD in all models (Models 1, 2, and 3, P < .05). In model 3, individuals in the highest tertile of FII had an odds ratio (OR) of 1.21 [95% confidence interval (CI): 1.11-1.32] for MAFLD, compared to those in the lowest tertile. Subgroup analyses and interaction tests revealed sex- and race-specific associations between FII and MAFLD. Among non-Hispanic whites, the optimal FII threshold for preventing MAFLD was found to be -11.56. A lower FII was associated with a lower prevalence of MAFLD. The impact of FII on MAFLD prevalence was more pronounced among non-Hispanic whites compared to other racial groups. An FII score of < -11.56 for daily food intake was associated with a reduced risk of MAFLD in non-Hispanic whites.\n\nID: 42245952\nTitle: The immunometabolic mechanisms and therapeutic targets of metabolic dysfunction-associated steatohepatitis.\nAbstract: Metabolic dysfunction-Associated Steatohepatitis (MASH) is a progressive subtype of Metabolic dysfunction-Associated Steatotic Liver Disease (MASLD) characterized by hepatic steatosis, inflammation, hepatocellular injury, and fibrosis, which may evolve to cirrhosis and hepatocellular carcinoma. Despite its growing global burden, no widely approved pharmacotherapy is available, highlighting the need to elucidate immunometabolic mechanisms and identify effective therapeutic targets. This review summarizes the epidemiology and clinical features of MASH and focuses on key pathogenic pathways, including insulin resistance, lipotoxicity, mitochondrial dysfunction, and gut-liver axis disturbance. Immune dysregulation mediated by Kupffer cell activation, macrophage polarization, inflammasome signaling, and cytokine networks is discussed in depth. The critical role of immunometabolic crosstalk in disease progression is emphasized. Current and emerging therapeutic targets-such as PPARs, FXR, THR-β, the GLP-1/FGF21 axis, DGAT2, and CCR2/CCR5-are systematically reviewed, together with advances in oligonucleotide therapy, cell-based interventions, and combination strategies. MASH results from the complex coupling of metabolic imbalance and immune-driven inflammation, making single-target therapy insufficient. Precision stratification based on immunometabolic networks and multi-target interventions represent promising directions for future drug development and individualized treatment.\n\nID: 42231130\nTitle: Green synergistic non-thermal processing of Xinhui Chenpi: targeted fraction screening and mechanistic elucidation of antioxidant enhancement in Caenorhabditis elegans.\nAbstract: Xinhui Chenpi (CP) is rich in polyphenols and flavonoids with excellent bioactivity, but its high-value biomass utilization is restricted. Green non-thermal processing can effectively maintain the structural integrity of bioactive small molecules, which is promising for the efficient valorization of CP resources. However, targeted preparation of high-activity CP fractions and their in vivo antioxidant mechanisms, as well as potential targets against alcoholic fatty liver (AFL), remain poorly clarified. A high-activity CP fraction (CPSU-H) was selectively prepared via pulsed electric field-ultrasonic synergistic extraction, ethanol polarity grading fractionation and HPD100 macroporous resin adsorption purification. CPSU-H significantly reduced malondialdehyde content to 0.32 ± 0.07 nmol mg protein-1 in Caenorhabditis elegans, and increased total superoxide dismutase, glutathione peroxidase and catalase activities to 80.35 ± 2.15, 148.73 ± 9.05 and 9.74 ± 0.52 U mg protein-1, respectively, showing strong in vivo antioxidant enhancement under non-stressed conditions. CPSU-H was dominated by neohesperidin and narirutin; nucleocytoplasmic transport pathway, longevity regulating pathway and nucleotide metabolism pathway were speculated to serve as the core signaling and metabolic pathways for its antioxidant enhancement. In addition, it could exert potential intervention effect on AFL through targeting proteins PTGS2, TNF, SRC, MMP9 and EGFR. This study realizes the directional green preparation of CPSU-H and clarifies its antioxidant mechanism under non-stressed conditions and AFL-related target proteins. The findings support the potential development of CPSU-H as natural antioxidants and functional food components, and provide a theoretical basis for high-value utilization of CP biomass and extended application of synergistic non-thermal processing technologies. © 2026 Society of Chemical Industry.\n\nID: 42221502\nTitle: Therapeutic potential of natural compounds from medicinal and food homology substances targeting gut microbiota in lipid metabolism disorders.\nAbstract: Dyslipidemia contributes to chronic diseases such as non-alcoholic fatty liver disease (NAFLD), type 2 diabetes (T2DM), and obesity. Emerging evidence highlights gut dysbiosis as a key driver of abnormal lipid metabolism. This review examines how natural bioactive compounds from medicinal and food homology (MFH) substances regulate lipid metabolism by modulating the gut microbiome. It summarizes evidence on the modification of the microbiota-lipid metabolism axis by natural compounds from MFH substances and discusses the limitations of applications and their promise for preventing and treating metabolic diseases. By capitalizing on these microbiota-mediated effects, natural compounds may serve as a beneficial natural resource for adjusting lipid metabolism.\n\nID: 42217069\nTitle: Therapeutic effects of chitooligosaccharide-epigallocatechin gallate conjugate on NAFLD: impact on gut-liver axis, lipid metabolism, and inflammation in rats fed a high-fat diet.\nAbstract: Non-alcoholic fatty liver disease (NAFLD) is a progressive disorder correlated with hepatic lipid homeostasis, gut dysbiosis, and inflammation. In this study, we propose a novel dietary therapy for NAFLD utilizing a conjugate of chitooligosaccharide (COS) and epigallocatechin gallate (EGCG), as the underlying mechanisms of NAFLD remain unclear. NAFLD was induced in male Wistar rats by administering a high-fat diet (HFD) for 16 weeks, followed by administration of COS-EGCG conjugate (150, 300, and 600 mg/kg) for an additional four weeks. The treatment alleviated metabolic parameters, liver steatosis, and injury. It also reduced hepatic lipid accumulation by downregulating the expression of CD36, fatty acid synthase (FASN), and sterol regulatory element-binding protein 1c (SREBP-1c), while upregulating peroxisome proliferator-activated receptor alpha (PPARα), carnitine palmitoyltransferase 1 A (CPT1A), and microsomal triglyceride transfer protein (MTTP). Regarding the gut-liver axis, the conjugate modulated gut microbiota, reduced serum lipopolysaccharide (LPS) levels, and restored the expression of intestinal tight junction proteins (zonula occludens-1; ZO-1 and occludin). It also prevented liver inflammation induced by gut-derived LPS by suppressing the Toll-like receptor 4 (TLR4)/nuclear factor kappa B (NF-κB) signaling pathway. The results suggest that the COS-EGCG conjugate exerts therapeutic effects against NAFLD by regulating hepatic lipid metabolism, modulating the gut microbiota, and attenuating gut-derived LPS-induced liver inflammation.\n\nID: 42422421\nTitle: Case Report: Dramatic metabolic improvement with tirzepatide in a patient with acquired partial lipodystrophy following hematopoietic stem cell transplantation.\nAbstract: Acquired lipodystrophy is a rare disorder characterized by adipose tissue loss or dysfunction and is frequently associated with severe insulin resistance and metabolic complications. Metabolic complications of lipodystrophy have occasionally been reported after hematopoietic stem cell transplantation (HSCT), but their clinical features and optimal treatment strategies remain poorly defined. Tirzepatide, a dual agonist of the glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors, has recently emerged as a novel therapy for type 2 diabetes. We report a 37-year-old woman who underwent allogeneic HSCT at 12 years of age for relapsed acute lymphoblastic leukemia after a conditioning regimen including total body irradiation (TBI), high-dose cytarabine, and melphalan. She subsequently developed diabetes mellitus and fatty liver disease at 17 years of age. Although no apparent fat loss was initially recognized, lipodystrophy was clinically suspected based on severe insulin resistance and metabolic abnormalities disproportionate to her body habitus. Computed tomography at 37 years of age revealed region-specific fat loss extending from the lower back to the gluteal region. Glycemic control remained inadequate despite high-dose insulin therapy and sequential treatment with several GLP-1 receptor agonists. After initiation of tirzepatide, glycemic control improved dramatically, allowing complete discontinuation of insulin therapy. Body weight decreased modestly and hepatic steatosis improved. The high-molecular-weight (HMW)/total adiponectin ratio after treatment was elevated (64.0%), suggesting possible improvement in adipocyte secretory function. This case highlights acquired partial lipodystrophy developing after HSCT, supported by region-specific fat loss and characteristic metabolic abnormalities, and demonstrates a marked therapeutic response to tirzepatide. Dual incretin receptor agonism may represent a promising therapeutic strategy for severe insulin resistance associated with adipose tissue dysfunction, potentially through both weight-dependent and weight-independent mechanisms.\n\nID: 42421035\nTitle: The impact of synbiotic yogurt consumption on insulin-resistance surrogates, atherogenic and novel anthropometric indices in adults with metabolic syndrome: a randomized clinical trial.\nAbstract: Metabolic syndrome (MetS) represents a well-recognized contributor to cardiovascular risk, and synbiotics have recently gained attention as a potential dietary strategy for its management. The present study aimed to determine whether a novel synbiotic yogurt formulated with Lactobacillus plantarum, Lactobacillus pentosus, and the yeast Kluyveromyces marxianus affects atherogenic markers, cardiometabolic parameters, and insulin resistance surrogates in individuals among individuals diagnosed with MetS. A 12-week double-blind, standard-yogurt-controlled randomized clinical trial was conducted, enrolling 44 adults with MetS who were randomized to either 300 g/day of synbiotic yogurt (n = 22) or a matched control yogurt (n = 22); 41 (22 synbiotic, 19 control yogurt) completed and were analyzed. A comprehensive panel of cardiometabolic outcomes was evaluated at baseline and week 12, encompassing atherogenic indices including the Atherogenic Index of Plasma (AIP), Castelli's Risk Index-I (CRI-I), Castelli's Risk Index-II (CRI-II), Atherogenic Coefficient (AC), and oxidized low-density lipoprotein (ox-LDL); cardiometabolic measures including the Visceral Adiposity Index (VAI), Waist Triglyceride Index (WTI), and Cardiometabolic Index (CMI); body shape and adiposity indices including A Body Shape Index (ABSI), Body Roundness Index (BRI), Body Adiposity Index (BAI), Conicity Index, Abdominal Volume Index (AVI), and Weight-adjusted Waist Index (WWI); and surrogate markers of insulin resistance including the Triglyceride-Glucose Index (TyG), Hepatic Steatosis Index (HSI), triglyceride to high-density lipoprotein ratio (TG/HDL), TyG-Body Mass Index (TyG-BMI), TyG-Waist Circumference (TyG-WC), Metabolic Score for Insulin Resistance (METS-IR), and Lipid Accumulation Product (LAP). At the end of the 12-week period, statistically significant between-group differences were limited to four indices, namely CRI-I (p = 0.039), CRI-II (p = 0.038), AC (p = 0.039), and BAI (p = 0.027), all of which favored the control group. Within-group analyses indicated that the control arm experienced significant reductions in AIP, CRI-I, CRI-II, AC, TG/HDL, and METS-IR, whereas participants in the synbiotic arm demonstrated significant decreases only in TyG and TyG-BMI. No significant changes were observed in other indices. According to our findings, 12 weeks of daily synbiotic yogurt consumption did not significantly improve insulin resistance surrogates, atherogenic, and novel anthropometric indices in adults with MetS. Iranian Registry of Clinical Trials (registration ID: IRCT20220426054667N1; registration date: 2022-05-18).\n\nID: 42420150\nTitle: Sleeve gastrectomy versus Roux-en-Y gastric bypass for nonalcoholic fatty liver disease: a systematic review and meta-analysis.\nAbstract: The efficacy of sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) in the treatment of nonalcoholic fatty liver disease (NAFLD) has not been fully elucidated. The purpose of this systematic review and meta-analysis is to provide reliable evidence for clinical interpretation of the advantages and disadvantages of RYGB and SG in the treatment of NAFLD by directly comparing the efficacy of RYGB and SG in the treatment of NAFLD. All over the world. PubMed, Embase, Web of Science, and ClinicalTrials.gov were searched for relevant articles up to December 2025. Mean difference (MD) and 95% confidence interval (CI) were used for quantitative synthesis of continuous variables, and risk ratio and 95% CI were used for quantitative analysis of categorical variables. The primary outcomes of the study were changes in NAFLD activity score (NAS), fibrosis stage, and changes in liver enzymes (including alanine aminotransferase and aspartate aminotransferase) from initial to follow-up. Secondary outcomes included changes in body weight, body mass index, percentage total weight loss, and percentage excess weight loss. A total of 16 original studies were included in our final meta-analysis. Our primary analysis showed no significant overall difference between SG and RYGB in improving NAS (MD = .23, 95% CI: .69-1.16). Exploratory subgroup analyses suggested potential time-dependent patterns, although these varied by outcome: longer-term follow-up (> 1 year) was associated with a point estimate favoring RYGB for NAS (MD = .75, 95% CI: .03-1.47), but favoring SG for alanine aminotransferase reduction (MD = -5.92, 95% CI: -8.24 to 3.60). No significant between-group difference was observed for aspartate aminotransferase changes (P = .18), and RYGB was associated with greater weight loss. Given the exploratory nature of these subgroup analyses, these findings should be interpreted cautiously and considered hypothesis-generating. Metaregression analysis revealed that the difference in weight loss between procedures was significantly associated with the effect size for NAS improvement (β = -.11, 95% CI: -.21 to .01, P = .032) and accounted for 100% of the between-study heterogeneity (R2 = 100%). Although our primary analysis showed no significant overall difference between SG and RYGB in improving NAS, RYGB was associated with greater weight loss. Metaregression findings suggested that any potential histological advantage of RYGB may be largely attributable to its superior weight loss efficacy rather than to weight-independent mechanisms. Exploratory subgroup analyses suggested potential differences in long-term histological outcomes that varied across measures and should be considered hypothesis-generating. These findings warrant confirmation in future prospective studies.\n\nID: 42413475\nTitle: A liver phosphatase reprograms gut stem cells to drive hyperglycemia.\nAbstract: Why is fatty liver disease associated with hyperglycemia? In this issue, Ye, Wan, Liu, Deng, Zhang et al.1 propose an unexpected mechanism: hepatic alkaline phosphatase released from diseased liver suppresses intestinal stem cell differentiation into GLP-1-secreting L-cells. This study reveals a new pathogenic route of liver-intestine communication.\n\nID: 42406586\nTitle: Associations of 24-Hour Accelerometer-Measured Movement Behaviors with Chronic Liver Disease and the Mediating Role of Proteomics and Metabolomics.\nAbstract: This study aimed to investigate the associations of 24-hour movement behaviours with chronic liver disease (CLD) incidence and liver-related mortality. Data were derived from the UK Biobank cohort, comprising 86,746 participants with accelerometer-measured 24h movement behaviours. We estimated the associations of behaviours with CLD incidence and liver-related mortality using Cox proportional hazard models. We also identified behaviours-associated proteomic and metabolic signatures and their roles in mediating the associations. Moderate-to-vigorous physical activity (MVPA) was inversely associated with liver-related risks, with the hazard ratios (HRs) per standard deviation (SD) increase of 0.74 (0.67-0.80) for CLD, 0.68 (0.61-0.75) for metabolic-associated fatty liver disease (MASLD), 0.81 (0.68-0.95) for cirrhosis, and 0.77 (0.64-0.94) for liver-related mortality, respectively. Sedentary behaviour (SB) was associated with higher risks of incident CLD (HR per SD: 1.12, 95% CI: 1.05-1.19), MASLD (HR per SD: 1.14, 95% CI: 1.06-1.22), cirrhosis (HR per SD: 1.15, 95% CI: 1.01-1.31), and liver-related mortality (HR per SD: 1.27, 95% CI: 1.10-1.47). Reallocating time from other behaviours to MVPA was associated with lower risks of CLD incidence and liver-related mortality. Multi-omics analyses identified distinct proteomic and metabolic signatures for each behaviour, with MVPA-related proteomic signature potentially accounting for 18.2% and metabolic signature potentially accounting for 3.0% of the association between MVPA and CLD risk. A higher proportion of MVPA and a lower proportion of SB over a 24-hour period was associated with lower risks of CLD incidence and liver-related mortality. Proteomic and metabolic signatures of behaviours may partly account for these associations.\n\nID: 42399294\nTitle: Dynamic changes in body fat distribution, ectopic fat, and related metabolic improvement in response to weigt loss in obesity.\nAbstract: We investigated the effect of weight loss on fat accumulation in six different tissues and associated metabolic characteristics in individuals with obesity, non-alcoholic fatty liver disease (NAFLD), and the metabolic syndrome (MetS). Baseline assessments were done for individuals with obesity, NAFLD, and MetS (n=33), individuals with obesity (n=28), and lean individuals (n=27), and at 1 and 5 months for the NAFLD-MetS group during personalized weight loss intervention. All measured fat depots were increased in individuals with obesity compared with lean (p<0.001), whereas pancreas (p=0.024) and visceral fat (p=0.007) were elevated in the NAFLD-MetS group compared with the obesity control group. During weight loss, fat content was reduced in all investigated tissues after 1- and 5-months, except for erector spinae muscle fat that was reduced after 5 months. Finally, reductions in alanine aminotransferase, fasting plasma glucose and insulin, waist circumference, and diastolic blood pressure were key for explaining liver fat content after 5 months. Multiple fat depots were increased simultaneously in individuals with obesity, with personalized weight loss intervention leading to reductions in all investigated tissues, especially after 1 month, in individuals with obesity, NAFLD, and MetS. The trial registry number: NCT05699863.\n\nID: 42394492\nTitle: [Untargeted metabolomics-based exploration of potential metabolic biomarkers for subclinical atherosclerosis in metabolic-associated fatty liver disease].\nAbstract: Cardiovascular disease is the most common extrahepatic complication and leading cause of death in metabolic dysfunction‑associated fatty liver disease (MAFLD). However, early metabolic biomarkers for subclinical atherosclerosis (SA) in MAFLD patients remain unclear. This study used untargeted metabolomics to investigate serum metabolite and pathway changes associated with SA in MAFLD patients and to screen for potential serum metabolic biomarkers. From December 2023 to December 2024, 64 MAFLD patients with SA enrolled in the \"Pan-Vascular Cohort Study\" at the Health Management Medical Center of the Third Xiangya Hospital of Central South University were included as an experimental group, and 50 age- and sex-matched MAFLD patients without SA were included as controls. MAFLD was diagnosed according to the Guidelines for the Prevention and Treatment of Metabolic (Non-Alcoholic) Fatty Liver Disease (2024 Edition). SA was defined by the presence of multi-segment arterial plaques and/or peripheral arterial obstruction. Untargeted metabolomics profiling was performed using ultra-high performance liquid chromatography coupled with mass spectrometry. Differential metabolites were screened using fold change (FC) analysis, principal component analysis, and orthogonal partial least squares discriminant analysis. Receiver operating characteristic (ROC) curves evaluated diagnostic performance of differential metabolites, and pathway enrichment analysis identified metabolic pathways associated with MAFLD and atherosclerosis. Using selection criteria of FDR-corrected q<0.05 and FC >1.5 or <0.67, a total of 415 differential metabolites were identified between the 2 groups. The top 5 differential metabolites were lysophosphatidylcholine (18꞉3), chelerythrine, N,N-hexamethylene thiocarbamate S-ethyl ester, N-ethyl-o-crotonylmethylaniline, and lysophosphatidylcholine (18꞉1). ROC analysis based on support vector machine (SVM) modeling of these top 5 metabolites yielded an area under the curve of 1. Differential metabolites were mainly enriched in histidine metabolism, sphingolipid metabolism, glycerophospholipid metabolism, unsaturated fatty acid biosynthesis, tryptophan metabolism, and taurine/hypotaurine metabolism. The metabolic profiles of MAFLD patients with and without SA differ significantly. Key differential metabolites may serve as potential biomarkers for predicting atherosclerosis in MAFLD patients. 目的: 代谢相关脂肪性肝病(metabolic dysfunction‑associated fatty liver disease，MAFLD)最常见的肝外并发症及死因是心血管疾病，MAFLD患者发生亚临床动脉粥样硬化(subclinical atherosclerosis，SA)的早期代谢标志物目前尚不明确。本研究通过非靶向代谢组学探索MAFLD患者发生SA的血清代谢物及代谢途径的变化，筛选潜在的血清代谢标志物。方法: 选取2023年12月至2024年12月在中南大学湘雅三医院健康管理医学中心“泛血管队列研究”纳入的64例MAFLD合并SA患者作为实验组，同期选取50例年龄、性别匹配的MAFLD未合并SA的受检者作为对照组。MAFLD诊断标准参照《代谢相关(非酒精性)脂肪性肝病防治指南(2024年版)》，采用多血管节段动脉粥样硬化斑块定义SA。使用超高效液相色谱和质谱仪进行非靶向代谢组学检测。采用差异倍数(fold change，FC)分析、主成分分析和正交偏最小二乘判别分析方法筛选差异代谢物，受试者操作特征(receiver operating characteristic，ROC)曲线评价差异代谢物的诊断效能，通路富集分析方法筛选与MAFLD及动脉粥样硬化发生相关的通路。结果: 基于差异代谢物筛选标准错误发现率(false discovery rate，FDR)-corrected q<0.05，FC>1.5或<0.67)，2组间共筛选出415个差异代谢物。排名前5的差异代谢物为溶血磷脂酰胆碱(18꞉3)、白屈菜红碱、N,N-六亚甲基硫代氨基甲酸-S-乙酯、N-乙基-邻巴豆酰甲基苯胺、溶血磷脂酰胆碱(18꞉1)。选取这5个差异代谢物使用支持向量机(support vector machine，SVM)进行建模并绘制ROC曲线，曲线下面积为1。差异代谢物主要富集于组氨酸代谢、鞘脂代谢、甘油磷脂代谢、不饱和脂肪酸生物合成、色氨酸代谢、牛磺酸与亚牛磺酸代谢等通路。结论: MAFLD患者是否发生SA的代谢谱存在显著差异，关键差异代谢物可能是预测MAFLD患者是否发生动脉粥样硬化的潜在生物标志物。.\n\nID: 42392673\nTitle: Liver fibrosis in metabolic dysfunction-associated steatotic liver disease: epidemiology, risk stratification and therapeutics.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) has become the most prevalent chronic liver disease worldwide and is tightly linked to cardiometabolic comorbidities. A major clinical focus on MASLD is the detection of hepatic fibrosis, which most strongly predicts liver-related events, hepatocellular carcinoma risk and mortality. While lifestyle modification and sustained weight loss remain foundational, therapeutic innovation has rapidly expanded, shifting the metabolic dysfunction-associated steatohepatitis (MASH) treatment landscape towards targeted pharmacotherapies that address metabolic stress, inflammation and fibrogenesis, particularly for moderate/advanced fibrosis (i.e., F2/F3 fibrosis and cirrhosis). This review summarises the burden and systemic complications of MASLD, highlights endocrine influences that modulate hepatic steatosis and disease severity and emphasises the central role of fibrosis staging and non-invasive risk stratification in clinical decision-making. We then synthesise emerging pharmacotherapies across key mechanistic axes, including incretin-based agents (GLP-1 receptor agonists and dual/triple agonists), hepatocyte-directed metabolic modulators (thyroid hormone receptor-β agonists, fatty acid synthase inhibitors, acetyl-CoA carboxylase and other de novo lipogenesis inhibitors), bile acid pathway therapies (FXR agonists) and pleiotropic metabolic-fibrotic regulators (fibroblast growth factor 21 [FGF21] analogues and peroxisome proliferator-activated receptor [PPAR] agonists). We also discuss combination strategies, candidate agents with potential direct antifibrotic activity and the growing role of genetic risk stratification and hepatocyte-targeted oligonucleotide therapeutics. Finally, we outline current surrogate endpoints used in clinical trials and propose future directions towards stage-specific, mechanism-informed and combination regimens to achieve persistent MASH resolution and meaningful fibrosis regression.\n\nID: 42392304\nTitle: Moderate-altitude hypoxia is associated with attenuated diet-induced liver injury and coordinated carbon-metabolic and lipid remodeling.\nAbstract: Chronic mild hypoxia at moderate altitude (2260 m) has been linked to improved systemic metabolism, but its liver-specific associations under high-energy diets remain incompletely defined. In this study, age-matched male C57BL/6 J mice were maintained for 15 weeks at simulated low altitude (50 m) or moderate altitude (2260 m) while fed a normal diet (ND), high-fat diet (HFD), or HFD with 30% fructose (HFD + HFr). Hepatic outcomes were assessed using ultrasonography, histology, electron microscopy, serum biochemistry, targeted energy metabolomics, lipidomics, and immunoblotting. Compared with the corresponding low-altitude high-energy diet groups, mice at 2260 m showed lower diet-associated weight gain, hepatic steatosis, and ALT/AST elevations. Structural analyses showed reduced lipid-droplet accumulation and qualitatively improved mitochondrial ultrastructural appearance. Metabolomics showed coordinated decreases in steady-state intermediates across glycolysis, the pentose phosphate pathway, and the tricarboxylic acid cycle relative to the 50 m HFD group, together with enzyme changes consistent with reduced lipogenic capacity and altered fatty-acid uptake/oxidation. Lipidomic profiling further showed lower accumulation of neutral lipids, including triglycerides and diacylglycerols, as well as sphingolipids, while phospholipid class-level composition appeared less disturbed. Overall, moderate-altitude exposure was associated with attenuation of high-energy-diet-related hepatic metabolic dysfunction and with coordinated metabolic remodeling. These findings identify chronic mild hypoxia as an important contextual factor associated with hepatic metabolic responses, while direct causal mechanisms require further validation.\n\nID: 42382779\nTitle: Nurr1 deficiency orchestrates a coupled liver-gut pathological axis revealed by multi-omics and deep-learning histopathology.\nAbstract: The nuclear receptor Nurr1 (NR4A2) is a transcriptional regulator of inflammatory homeostasis, but its systemic effects on orchestrating inter-organ communications are largely unknown. Here we show that Nurr1 haplo-insufficiency results in a lethal coupled disorder across the liver-gut axis. Using a CRISPR-Cas9 generated murine model, we find that metabolically-activated heterozygous deficiency of Nurr1 results in profound hepatocellular necrosis and marked hepatic activation of inflammatory and pro-fibrotic genes coupled with dysregulation of the intestinal barrier, and severe small-intestinal dysbiosis. Multi-omics integration reveals a highly penetrant transcriptional signature of this herein termed liver-gut disorder, achieving up to 0.950 accuracy (SVM-RBF, 10-fold cross-validation) in classifying genotypes from integrated multi-omics features. Notably, we also demonstrate that these gene level perturbations in Nurr1 haplo-insufficiency can be thought of as learnable tissue 'morphologies' detectable by AI. Next, we created deep convolutional neural networks that accurately classify genotype from routine histopathology. Our algorithm achieves 99.50% accuracy in classifying hepatic fibrosis (Sirius Red), 99.20% in liver inflammation (H&E) and 92.31% in intestine (H&E). We provide the first multi-omics phenotype of Nurr1 deficiency, revealing its pivotal regulatory role in coordinating liver-gut homeostasis, and establishing a histopathological AI-driven framework. Grad-CAM saliency analysis confirms biological interpretability. Translational relevance is supported by human transcriptomic data (E-GEOD-61260) showing concordant upregulation of COL1A1 (log2FC= + 0.725, p < 0.01), TGFB1 (+ 0.429, p < 0.05), and MMP9 (+ 0.969, p < 0.01) alongside reduced NR4A2/NURR1 in human liver disease.\n\nID: 42365696\nTitle: Apigenin ameliorates methionine-choline deficient diet-induced metabolic-associated fatty liver disease through modulation of gut microbiota-liver axis.\nAbstract: Apigenin, a naturally occurring flavone widely present in the plant kingdom, possesses antioxidant, anti-inflammatory, and metabolic regulatory activities. Metabolic-associated fatty liver disease (MAFLD), a chronic liver disorder driven by metabolic stress, currently lacks effective pharmacological therapies. Given these pharmacological properties, apigenin may represent a promising candidate for MAFLD intervention. This study aimed to evaluate the therapeutic potential of apigenin in MAFLD and to elucidate the underlying mechanisms linking the gut microbiota and host lipid metabolism. A methionine-choline deficient (MCD) diet-induced mouse model of MAFLD, combined with lipidomic profiling, microbiota analysis, and metabolite assessment, was used to determine the beneficial effects of apigenin. Apigenin markedly ameliorated hepatic steatosis in MCD-fed mice, as demonstrated by reduced hepatic triglyceride accumulation, improved liver function markers, and alleviated hepatic inflammation and oxidative stress. Lipidomic profiling showed decreased hepatic saturated and polyunsaturated fatty acids accompanied by an increase in monounsaturated fatty acids and their related lipid species. Apigenin remodeled the gut microbiota, characterized by increased Lactobacillus abundance and decreased Akkermansia abundance. Further analyses identified homocysteine (HCY) as a key microbiota-associated metabolite that induced oxidative stress and reproduced the lipid dysregulation observed in MAFLD, thereby linking microbial alterations to hepatic lipid metabolism. These findings demonstrate that apigenin alleviates MAFLD by remodeling the gut microbiota-metabolite network, lowering HCY levels, and subsequently improving hepatic function, lipid metabolism, and oxidative stress, highlighting its potential as a phytochemical-based therapeutic strategy.\n\nID: 42357514\nTitle: Exploring Active Ingredients and Mechanisms of Crataegi fructus Extract in Alleviating MAFLD via the AMPK/PPAR Pathway by Multi-Omics.\nAbstract: The fruit of Crataegi fructus (CF) is a traditional \"medicine food\" herb widely used for its lipid-lowering properties, but its active ingredients and mechanisms against metabolic dysfunction-associated fatty liver disease (MAFLD) remain poorly understood. This study employed an integrated multi-omics approach, combining serum metabolomics, liver transcriptomics, weighted gene co-expression network analysis (WGCNA), network pharmacology, and molecular docking, to systematically investigate the effects of CF extract (CFE) in a high-fat diet (HFD)-induced mouse model of MAFLD. Our analysis revealed that CFE treatment significantly reduced body weight gain (p < 0.01), improved glucose tolerance and insulin sensitivity (p < 0.01), and alleviated hepatic steatosis, as evidenced by reduced lipid accumulation and decreased NAS scores (p < 0.001). Metabolomics analysis showed that CFE reversed HFD-induced disturbances in serum fatty acids, glycerophospholipids, and bile acid metabolites. Transcriptomics further revealed that the AMPK and PPAR signalling pathways were critically involved in the regulation of lipid metabolism by which CFE alleviated MAFLD. Consistently, CFE treatment resulted in significant upregulation of AMPK and PPARα expression (p < 0.001) and downregulation of CD36 and DPP4 (p < 0.001), as confirmed by Western blotting and qPCR. Furthermore, integration of WGCNA and network pharmacology pinpointed chlorogenic acid (CA), ursolic acid (UA), and oleanolic acid (OA) as the primary bioactive components, and their lipid-lowering effects were validated in FFA-treated THLE-2 cells. In conclusion, this study offers preliminary insights into the lipid-lowering mechanisms of CFE via regulation of the AMPK/PPARα/CD36/DPP4 signalling pathway and support its further development as a functional food ingredient for MAFLD prevention.\n\nID: 42353331\nTitle: Therapeutic Effects of Glucagon-like Peptide-1 Receptor Agonists in Non-Alcoholic Fatty Liver Disease: A Systematic Review.\nAbstract: Non-alcoholic fatty liver disease (NAFLD), now increasingly termed metabolic dysfunction-associated steatotic liver disease (MASLD), is a growing cause of chronic liver disease with limited treatment options. Glucagon-like peptide-1 (GLP-1) receptor agonists, approved for type 2 diabetes and obesity, possess metabolic effects that may render them suitable for treating NAFLD and metabolic dysfunction-associated steatohepatitis (MASH). To evaluate the therapeutic effects of GLP-1 receptor agonists in adults with NAFLD, non-alcoholic steatohepatitis (NASH), MASLD, or MASH. PubMed, Scopus, Embase, and the Cochrane Library were systematically searched using keywords related to NAFLD and GLP-1 receptor agonists. Given heterogeneity in populations, designs, and outcomes, findings were synthesized narratively. The review is registered with PROSPERO (CRD420261337353). Twelve studies met the inclusion criteria. The most consistent outcome was a reduction in hepatic fat, seen with semaglutide, liraglutide, dulaglutide, and beinaglutide. Improvements in liver enzymes, particularly alanine aminotransferase, were less consistent and best regarded as supportive rather than definitive evidence of histological improvement. Histological benefits were strongest for steatohepatitis resolution in non-cirrhotic MASH. Fibrosis findings were mixed, with the greatest benefit in F2-F3 MASH and limited improvement in established cirrhosis. GLP-1 receptor agonists were generally well tolerated, with gastrointestinal symptoms the most common adverse effects. GLP-1 receptor agonists show promising liver-related benefits in NAFLD and MASH, particularly in obesity, type 2 diabetes, or earlier-stage disease. Their effects on advanced fibrosis and long-term outcomes remain uncertain, warranting larger, longer-term studies.\n\nID: 42352035\nTitle: Sex-Specific and Reproductive Status-Dependent Effects of Liraglutide on Metabolic Disorders Associated with Prediabetes.\nAbstract: Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have been shown to have beneficial effects in T2D, reducing hepatic lipid storage and improving metabolic dysfunction-associated steatotic liver disease. However, sex and reproductive age may influence their effect. We investigated the effect of liraglutide administration (0.2 mg/kg/day subcutaneously for 8 weeks) on metabolic disorders in relation to sex and reproductive age, using male, female and ovariectomized female hereditary hypertriglyceridemic (HHTg) rats as a prediabetic model. Liraglutide improved glucose tolerance in all HHTg rats. Female and ovariectomized (OVX) female rats showed a stronger effect of lipid metabolism and visceral adiposity than males. Moreover, no changes in hepatic triacylglycerol (TAG) accumulation were observed in males. Liraglutide partially reversed ovariectomy effects, such as increased body weight, visceral obesity and impaired glucose tolerance. Compared with males, female and OVX female rats showed more significant changes in hepatic gene expression involved in lipogenesis (Scd-1, Srebp1, Pparγ), fatty acid and lipid metabolism (Pparα, Hmgcr, Srebp2) and fibrosis (Tgfβ), which may improve hepatic lipid metabolism. Females of fertile age showed greater improvements in insulin sensitivity, reductions in ectopic lipid accumulation, and improvements in lipid metabolism. Depending on sex and reproductive status, liraglutide can mitigate fatty liver before diabetes onset.\n\nID: 42348222\nTitle: Cost-Effectiveness of Pharmacologic Therapies for Metabolic Dysfunction-Associated Steatohepatitis With Significant Fibrosis in the United States.\nAbstract: The approval of new pharmacotherapies for metabolic dysfunction-associated steatohepatitis (MASH) presents a critical need for value assessment. We evaluated the cost-effectiveness of resmetirom, semaglutide and tirzepatide for U.S. adults with MASH and F2-F3 fibrosis. We developed a Markov cohort model with a lifetime horizon from the perspective of a U.S. healthcare payer. The model simulated biopsy-confirmed patients with MASH progressing through liver-specific health states. Efficacy inputs for fibrosis regression and MASH resolution were obtained from a Bayesian network meta-analysis. Each pharmacotherapy was compared individually against standard of care; a formal sequential incremental analysis across active therapies was not performed. Cost-effectiveness was assessed against the standard of care using a $100 000/QALY willingness-to-pay threshold. In the base-case analysis, tirzepatide had the largest QALY gain and the lowest incremental cost relative to standard of care, yielding an incremental cost-effectiveness ratio of ($42 705/QALY). Semaglutide was also cost-effective (ICER: $80 076/QALY). Resmetirom (ICER: $273 445/QALY) exceeded the WTP threshold. Drug price was the most influential parameter in sensitivity analyses; probabilistic sensitivity analysis showed a 99.5% probability of cost-effectiveness for tirzepatide and 89.8% for semaglutide at $100 000/QALY. At current U.S. prices, tirzepatide and semaglutide are cost-effective for MASH with F2-F3 fibrosis, while resmetirom is not. The tirzepatide finding should be interpreted with caution, given that it is not yet FDA-approved for MASH and its effect estimate is based on a network meta-analysis of a phase 2 trial. Payer coverage and equitable access to MASH therapies require value-based pricing strategies.\n\nID: 42345773\nTitle: Dietary Chlorogenic Acid Attenuates Hepatic Lipid Accumulation and Reprograms Lipid Metabolism in Heat-Stressed Laying Hens: Integrated Transcriptomic and Metabolomic Analyses.\nAbstract: Heat stress leads to excessive hepatic lipid deposition and oxidative imbalance in laying hens, especially during peak laying period. Chlorogenic acid (CGA), a dietary polyphenol with antioxidant and lipid-modulating properties, may improve hepatic lipid homeostasis, yet its effects under heat-stress conditions remain unclear. In this study, 240 Hy-Line Brown laying hens at 36 weeks of age were randomly assigned to one of two treatments (120 hens per treatment, with six replicates of 20 hens each): a basal diet or a basal diet supplemented with 300 mg/kg CGA and subjected to heat-stress conditions for 8 weeks. CGA supplementation significantly reduced liver weight (25.3%), liver index (14.4%), hepatic triglyceride content (29.1%), and serum triglyceride level (61.7%) (p < 0.05). Histological assessment revealed lower steatosis and inflammation scores, alongside increased hepatic SOD activity (13.6%) and decreased MDA content (58.7%) (p < 0.05). RNA-seq analysis identified 420 differentially expressed genes that were significantly enriched in PPAR signaling and fatty acid β-oxidation pathways. CGA upregulated fatty acid oxidation-related genes (ACSL1, CPT1A, ACOX1, ACAA1) and downregulated lipogenic markers (FASN, ACACA). Serum metabolomics revealed coordinated changes in lipid and carbon metabolism. These results indicate that dietary CGA alleviates hepatic lipid accumulation and oxidative stress in heat-stressed peak-laying hens, potentially via PPARα-mediated enhancement of fatty acid oxidation and inhibition of de novo lipogenesis.\n\nID: 42331736\nTitle: Glucagon-Like Peptide-1 Receptor Agonists and Incident Major Adverse Liver Outcomes in People With Type 2 Diabetes and Metabolic Dysfunction-Associated Steatotic Liver Disease.\nAbstract: Treatment options for metabolic dysfunction-associated steatotic liver disease (MASLD) are limited. While glucagon-like peptide-1 receptor agonists (GLP-1 RA) and sodium-glucose cotransporter-2 (SGLT-2) inhibitors improve cardiovascular outcomes, comparative effectiveness on liver-related outcomes remains unclear. This study compared the effectiveness of GLP-1 RAs versus SGLT-2 inhibitors on major adverse liver outcomes (MALO), liver cirrhosis and all-cause mortality in people with MASLD and type 2 diabetes. This active comparator, new-user cohort study used claims data from Germany (2005-2024), including 45 256 people with MASLD and type 2 diabetes. New users of GLP-1 RAs (n = 9993) and SGLT-2 inhibitors (n = 35 263) were weighted using matching weights. The primary outcome was MALO, while secondary outcomes comprised individual MALO components (decompensation events, liver transplantation, hepatocellular carcinoma (HCC)), liver cirrhosis and all-cause mortality. Hazard ratios (HR) with 95% confidence intervals (CI) were estimated with weighted Cox proportional hazard models. Over a median 4.3-year follow-up, new users of GLP-1 RAs had a lower hazard of MALO (HR 0.91, 95% CI 0.78-1.07). This association appeared stronger using an on-treatment approach (HR 0.78, 95% CI 0.58-1.03) and when restricting to hospital diagnoses in primary position (HR 0.77, 95% CI 0.56-1.07). Benefits were also observed for liver cirrhosis (HR 0.88), decompensation events (HR 0.91), HCC (HR 0.76), but not all-cause mortality (HR 1.04). GLP-1 RAs were associated with a potentially lower hazard for incident MALO and liver cirrhosis compared with SGLT-2 inhibitors in people with MASLD and type 2 diabetes, suggesting a possible therapeutic advantage for liver-specific outcomes in this population.\n\nID: 42327723\nTitle: Hidradenitis suppurativa and psoriasis: shared immunological links with metabolic-associated steatotic liver disease.\nAbstract: Chronic inflammatory skin conditions such as hidradenitis suppurativa and psoriasis vulgaris exhibit a significantly elevated prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD), with studies indicating rates as high as 57% among affected individuals. This narrative review explores the underlying immunological mechanisms that connect HS and psoriasis with MASLD, emphasising the role of chronic systemic inflammation, immune dysregulation, and shared immunologic links between the diseases. This article also urges for enhanced awareness among dermatologists regarding the potential pharmacological interventions for patients with concurrent HS or psoriasis and MASLD, including glucagon-like peptide-1 receptor agonists and biologics, while acknowledging the need for further research to elucidate the efficacy and safety of these treatments.\n\nID: 42327337\nTitle: Perinatal Semaglutide Treatment Improves Maternal Health and Mitigates Offspring Metabolic Dysfunction in a Mouse Model of Maternal Obesity.\nAbstract: Early-life exposures during critical periods of development significantly impact lifelong metabolic risk and likely contribute to the rising rates of obesity, type 2 diabetes, and metabolic dysfunction-associated steatotic liver disease (MASLD) in children. Here, we evaluated the safety and metabolic effects of semaglutide, a GLP-1 receptor agonist (GLP-1 RA), administered from preconception through lactation in dams fed a high-fat diet (HFD) or standard diet, and assessed metabolic outcomes in dams and their offspring. Offspring were weaned to a standard diet. We found that semaglutide improved body composition and glucose metabolism in HFD-fed dams during pregnancy. These maternal changes persisted 10 weeks after weaning despite discontinuation of semaglutide treatment. HFD exposure impaired glucose homeostasis and promoted hepatic steatosis in offspring at 18 weeks. These effects were ameliorated by maternal semaglutide treatment. Importantly, metabolic improvements in dams and offspring occurred without adverse effects on conception rate or fetal viability. These findings suggest that GLP-1 RA during the perinatal period can improve maternal and offspring metabolic health in a mouse model of obesity and support further investigation of GLP-1-based therapies to mitigate maternal metabolic dysfunction and improve metabolic risk in children. Rates of obesity, type 2 diabetes, and fatty liver disease are rising in children, in part due to maternal obesity and insulin resistance that program offspring metabolic risk during the perinatal period.We asked whether the GLP-1 receptor agonist (GLP-1 RA), semaglutide, administered during critical developmental windows could prevent adverse outcomes in offspring using a diet-induced mouse model of maternal obesity.Semaglutide, given to dams from preconception through lactation, improved maternal metabolism and ameliorated metabolic dysfunction in offspring caused by maternal high-fat diet.These findings highlight a potential role for perinatal GLP-1 receptor agonism to improve maternal metabolic health and reduce metabolic risk in offspring.\n\nID: 42318205\nTitle: Effects of SGLT-2 inhibitors and GLP-1 receptor agonists on liver function in patients with non-alcoholic fatty liver disease and type 2 diabetes.\nAbstract: The goal was having the comparisons be direct when it came to seeing how much of a help the sodium-glucose co transporter - 2 inhibitors (SGTL2is) compared to the glucagon-like peptide-1 receptor agonists (GLP-1RAs) were in regard to how the liver enzymes performed within people having type 2 diabetes (T2D) along with nonalcoholic fatty liver disease (NAFLD), a condition characterized by excessive fat accumulation in the liver without alcohol overconsumption. A total of 705 subjects with T2DM and NAFLD at time of first SGLT2is (n=381) or GLP-1RAs (n=324) enrolment in this multicentre posterior cohort study from 01/2020-12/2024. Baseline characteristics were made equivalent via PSM via a 1: 1 NN match and a 0. 2 SD match clamp. The main measurement was the difference in alanine amino transferase (ΔALT) and aspartate aminotransferase (ΔAST) from the beginning and 6 months. And other result was about the change in metabolic parametres. The independent predictors of liver-enzyme change came from the multivariate linear regression analysis. After PSM, 243 well-matched pairs were successfully identified, with baseline characteristics acceptably balanced (standardized differences <0.2 for all covariates and <0.1 for most covariates). In the matched cohort, SGLT2is treatment was associated with significantly greater reductions in ALT (ΔALT: -10.55 ± 12.66 vs. -7.28 ± 15.34 U/L, p=0.011) and AST (ΔAST: -7.68 ± 10.07 vs. -5.18 ± 11.04 U/L, p=0.010) compared to GLP-1RAs treatment. No significant differences were observed for changes in GGT, body weight, glycemic control, or lipid profiles between groups. Multivariable regression analysis revealed that SGLT2is treatment was independently associated with reductions in both ALT (β = -3.34, p=0.009) and AST (β = -2.32, p=0.016). Weight change was independently associated with AST reduction (β = 0.22, p=0.016) but not with ALT reduction. SGLT2is were associated with greater ALT and AST reductions than GLP-1RAs in T2D patients with NAFLD, with ALT improvement independent of weight loss, suggesting potential direct hepatoprotective effects.\n\nID: 42315051\nTitle: Microbial metabolites contribute to the pathogenesis of metabolic dysfunction-associated fatty liver disease in high-fat diet-fed mice.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) affects approximately one-third of the global population and is a leading cause of chronic liver disease. Understanding the underlying metabolic pathways offers valuable insights into disease progression and potential therapeutic approaches. Dysregulation of the gut-liver axis and microbial imbalance contribute to MASLD progression by compromising intestinal barrier integrity, altering microbe-mediated metabolites, and promoting chronic hepatic inflammation. However, the specific metabolic disruptions in MASLD and the mechanisms through which microbes and their metabolites influence liver injury remain poorly understood. Six-week-old C57BL/6J mice were randomly assigned to five groups: baseline, normal chow (NC)_8w, NC_16w, MASLD_8w, and MASLD_16w. Mice in the MASLD groups were fed a high-fat diet (HFD), while the control groups were fed an NC diet. Body weight, liver function, and histopathological changes were evaluated, along with hepatic metabolomic profiling and fecal 16S ribosomal RNA gene sequencing. HFD-fed MASLD mice exhibited significant liver dysfunction, hepatic lipid accumulation, and increased body weight, triglycerides (TG), and cholesterol (CHO). Metabolomic analysis revealed marked disruption of hepatic metabolic homeostasis, particularly in lipid metabolism. Arachidonic acid metabolism was significantly altered and accompanied by increased levels of inflammatory mediators, including arachidonic acid (AA) and prostaglandin E2. In parallel, the relative abundance of Enterobacteriaceae was elevated in MASLD mice and showed a significant positive correlation with the hepatic accumulation of phosphatidylcholine (PC) (18:4(6Z,9Z,12Z,15Z)/16:1(9Z)), a phosphatidylcholine species annotated as a potential precursor of arachidonic acid. This coordinated alteration in gut microbial composition and hepatic lipid metabolites was associated with hepatic inflammatory responses in MASLD. Our findings demonstrate that hepatic inflammatory activation in MASLD is closely associated with reprogramming of the AA metabolic pathway. The observed Enterobacteriaceae-PC-AA correlation provides a potential mechanistic explanation for gut-liver crosstalk in MASLD progression, and may serve as a promising non-invasive biomarker candidate and therapeutic target for further functional validation.\n\nID: 42311944\nTitle: Dendrobium officinale polysaccharide ameliorates high-fat diet-induced hepatic lipid metabolic disorder via the SIRT6/PGC-1α signaling axis.\nAbstract: This study aims to explore the potential therapeutic effect of Dendrobium officinale polysaccharide (DOP) on non-alcoholic fatty liver disease (NAFLD) induced by high-fat diet (HFD), and to elucidate the underlying mechanism involving the SIRT6/PGC-1α signaling axis and the regulation of the gut microbiota. We extracted and characterized DOP. We established a rat model of NAFLD induced by HFD and evaluated the efficacy of DOP by integrating multi-omics techniques (transcriptomics, metabolomics) and 16S rRNA sequencing. To verify the specific role of SIRT6, we introduced the SIRT6 inhibitor OSS_128167 in the primary hepatocyte model induced by oleic acid/palmitic acid (OA/PA). DOP significantly alleviated liver steatosis, oxidative stress, and lipid metabolism disorders induced by HFD. Multi-omics analysis indicated that DOP regulated liver glycerophospholipid metabolism and restored intestinal microbiota homeostasis, significantly increasing the abundance of beneficial bacteria such as Lactobacillus. Mechanistically, DOP activated the liver SIRT6/PGC-1α signaling axis, thereby enhancing antioxidant defense and inhibiting lipogenesis. Crucially, in vitro experiments confirmed that the SIRT6 inhibitor OSS_128167 eliminated the protective effect of DOP on lipid accumulation, confirming that the effect of DOP depends on SIRT6. DOP improves NAFLD through dual mechanisms of regulating the gut-liver axis homeostasis and directly activating the liver SIRT6/PGC-1α signaling pathway. The results of this study provide a theoretical basis for developing DOP as a drug for the treatment of NAFLD.\n\nID: 42310179\nTitle: CD59 drives diet-induced obesity and glucose intolerance, insulin resistance, and metabolic dysfunction-associated steatotic liver disease.\nAbstract: CD59 is known as a membrane-bound regulator of the complement system that prevents the formation of the membrane attack complex on host cells. Here we report the metabolic consequences of CD59a knockout (KO) in mice fed a high-fat diet (HFD). Mice lacking CD59a were protected from the development of insulin resistance, glucose intolerance, hyperinsulinemia, obesity, and fatty liver. Mutants fed an HFD had elevated adiponectin levels and reduced leptin levels in plasma. Data from metabolic cages suggested decreased appetite and an increase in voluntary wheel activity in mutants. Liver transcriptome analysis showed a marked decrease of inflammatory and fibrotic pathways in CD59a KO mice on an HFD, and plasma and liver metabolomics were remarkably similar, indicating close correspondence between systemic and hepatic metabolic profiles. In conclusion, we uncover a noncanonical role of CD59a in the development of diet-induced insulin resistance, hyperinsulinemia, glucose intolerance, and obesity.\n\nID: 42307179\nTitle: The evolving therapeutic landscape of gut-pancreatic peptide signalling in metabolic disorders: from mono- to multi-agonist therapies.\nAbstract: The pharmacotherapeutic landscape for the clinical management of type-2 diabetes (T2D), obesity, metabolic dysfunction-associated steatotic liver disease (MASLD), and steatohepatitis (MASH) is evolving swiftly in response to the escalating global prevalence and incidence of these interrelated metabolic disorders. Although insulin and metformin formulations have long constituted the foundation of diabetes care, a paradigm shift in T2D management has been observed with the advent of novel pharmacotherapies. Gut peptide analogues are at the forefront of this transformation. The emergence of glucagon-like peptide-1 (GLP-1) receptor agonists represents a watershed moment, fundamentally reshaping the therapeutic landscape for both T2D and obesity due to multifaceted metabolic benefits. The clinical success of GLP-1-based therapies has stimulated pharmaceutical interest in other metabolic peptides. Gut-pancreatic peptides such as glucose-dependent insulinotropic polypeptide (GIP), glucagon, amylin, and peptide YY (PYY) are of particular interest due to their distinct pharmacological benefits and therapeutic promise in metabolic disorders.

Guar gum and its enzymatic product, partially hydrolyzed guar gum (PHGG), are among the most studied dietary fibers in humans. Altogether, they can be described as \"guar fiber\". We performed a narrative review of the literature on guar fiber, namely guar gum and its partially hydrolyzed product, and their impact on human health, with a special focus on the gastrointestinal tract, gut microbiota, gut-brain axis, and liver steatosis. Accordingly, a literature search was conducted using the following keywords and combinations: guar fiber, guar gum, partially hydrolyzed guar gum, disorders of gut-brain interaction, gut-liver axis, and gut microbiota. Guar gum and its derivative, PHGG, show promising effects in gastrointestinal disorders, such as constipation and diarrhea. Interestingly, they can modulate the gut microbiota, with promising implications for the gut-brain axis and disorders of gut-brain interaction, such as irritable bowel syndrome. There are also interesting, albeit preliminary, results regarding their use in fatty liver disease. Thus, dietary fibers such as guar gum and, more importantly, its hydrolyzed product, show promising and better-documented effects on the health of the gastrointestinal tract and other organs and systems of the human body. However, the latter evidence still requires clinical confirmation of preclinical findings. Overall, the reviewed data vary in quality and maturity across different outcome domains.\n\nID: 42296782\nTitle: Macrophage plasticity as a therapeutic target in inflammatory bowel disease: Immunomodulatory and regenerative strategies.\nAbstract: Inflammatory bowel disease (IBD), which mainly includes Crohn's disease and ulcerative colitis, is a chronic inflammatory disorder of the gastrointestinal tract characterized by recurrent episodes of intestinal inflammation. The development of IBD is influenced by multiple factors, including genetic predisposition, intestinal dysbiosis, epithelial barrier impairment, and abnormal immune activation. Among innate immune cells, macrophages are key regulators of intestinal immune homeostasis and are involved in inflammatory responses, tissue remodeling, and mucosal repair. Their ability to adopt different functional states in response to local environmental signals has made them an important focus of current therapeutic research in IBD. Traditionally, macrophages have been classified into pro-inflammatory M1 and anti-inflammatory M2 phenotypes. However, recent findings from single-cell transcriptomic and spatial analyses suggest that intestinal macrophages represent a far more diverse and dynamic population than this simplified classification implies. Multiple macrophage subsets with inflammatory, regulatory, reparative, and fibrosis-associated functions coexist within the intestinal microenvironment and contribute differently to disease progression and tissue healing. These observations highlight the importance of developing more selective and targeted macrophage-based therapeutic approaches. In this review, we discuss the current understanding of macrophage plasticity and its role in the pathogenesis of IBD. Particular attention is given to newer macrophage-targeted therapeutic strategies, including adoptive macrophage transfer, engineered macrophages, receptor-targeted therapies, nanoparticle-based delivery systems, microbiome modulation, microbial metabolite regulation, gene-editing approaches, organoid technologies, and biomaterial-assisted platforms. We also examine the contribution of macrophages to epithelial regeneration, mucosal healing, fibrosis, and intestinal tissue remodeling. In addition, we address several major challenges that currently limit the clinical translation of macrophage-targeted therapies. A better understanding of macrophage biology, together with continued advances in immunology, regenerative medicine, microbiome research, and biomaterials science, may support the development of more precise and personalized therapeutic strategies for patients with IBD.\n\nID: 42429050\nTitle: Protective effects of Astragaloside IV on various liver diseases: From chemistry to herbal medicines (Review).\nAbstract: Numerous liver diseases are characterized by late diagnosis, rapid progression and high incidence, seriously threatening public health. Though widely used, traditional treatments such as drug therapy, resection and transplantation have substantial limitations. Therefore, developing novel preventive strategies and specialized therapies is crucial. As Chinese medicine continues to modernize, increasing evidence suggests that certain Chinese medicine ingredients can protect the liver. Astragaloside IV (AS‑IV) is a natural saponin extracted from the root of the traditional herb Astragalus membranaceous. It exhibits diverse pharmacological activities, including anti‑inflammatory, antioxidant, antiapoptotic and anticancer properties, and is recognized for treating neurological, cardiovascular and metabolic disorders, and cancer. These discoveries indicate its substantial promise for the treatment of liver diseases. Therapeutic trials revealed its hepatoprotective effects for the treatment of various liver diseases, such as non‑alcoholic fatty liver disease, liver fibrosis, hepatocellular carcinoma and liver injury induced by heavy metals, drugs, or alcohol and involve various signaling pathways such as nuclear factor erythroid 2‑related factor 2, toll‑like receptor 4, acetyl‑CoA carboxylase, protein kinase B, nuclear factor κB and adenosine monophosphate‑activated protein kinase. The present study presents a narrative review that comprehensively summarizes existing evidence regarding the therapeutic influence of AS‑IV on diverse liver disorders and deeply analyzes the molecular mechanisms underlying its action in liver disease. The objective is to comprehensively offer insights and references for relevant scientific research and clinical drug development to improve nutritional supplements for liver health.\n\nID: 42393642\nTitle: MCD biomarkers Egfr, Hmox1, Lgmn identified in NAFLD.\nAbstract: Non-alcoholic fatty liver disease (NAFLD) is associated with metabolic cell death (MCD), and this study aimed to dig deeper into the biomarkers associated with MCD in NAFLD, and to provide new references for the diagnosis and treatment of NAFLD. The datasets and MCD-related genes (MCD-RGs) associated with NAFLD were downloaded from the Gene Expression Omnibus (GEO) database and the literature, respectively. Differentially expressed genes (DEGs) between NAFLD and control groups were identified and intersected with MCD-RGs to yield candidate genes. Biomarkers were obtained by screening under four machine learning models, Receiver Operating Characteristic (ROC) curves, and expression validation. Based on the biomarkers, functional enrichment, diagnostic model construction, network modulation, and reverse transcription-quantitative polymerase chain reaction (RT-qPCR) were performed. At the same time, differential infiltration of immune cells in the NAFLD and control groups was analysed. The 17 candidate genes were mostly involved in processes such as immunity and apoptosis. After screening, Egfr, Hmox1, and Lgmn were identified as biomarkers. Among these, Egfr was down-regulated whereas Hmox1 and Lgmn were up-regulated in NAFLD. Based on these biomarkers, a nomogram diagnostic model was constructed and demonstrated excellent predictive performance (AUC = 0.997). Subsequent enrichment analyses showed enrichment in inflammatory regulation between biomarkers and NAFLD groups. In addition, in the TF-biomarker network, Egfr and Hmox1 co-predicted NF-κB1. SORAFENIB was co-predicted in drug prediction. Meanwhile, five differentially infiltrating immune cells, such as CD8 T cells, were found to be strongly negatively correlated (cor = -0.475) with Egfr in both the NAFLD and control groups. In this study, Egfr, Hmox1, and Lgmn were used as biomarkers showing transcriptomic correlation with with MCD in NAFLD, and an excellent nomogram diagnostic model was developed accordingly, which is expected to provide a practical tool for diagnosis and treatment of NAFLD. Not applicable.\n\nID: 42388495\nTitle: The impact of gut microbiome on intrahepatic cholestasis of pregnancy-systematic literature review.\nAbstract: In recent years, there has been a growing interest in the gut microbiome and its potential role in the etiopathogenesis of both gastrointestinal and extraintestinal diseases. Dysbiosis, characterized by a pathological alteration in the composition of the gut microbiome, has been implicated in various gastrointestinal diseases. This paradigm extends to pregnancy-specific conditions, including intrahepatic cholestasis of pregnancy (ICP). ICP exhibits a multifactorial etiopathogenesis, involving hormonal, genetic and environmental factors, among others. Despite growing scientific evidence, there is currently a lack of comprehensive reviews that specifically examine the causal mechanisms through which gut microbiota dysbiosis might contribute to the pathogenesis of ICP, as well as the resulting implications for the development of new targeted therapeutic approaches. Notably, shifts in microbial taxa and the depletion of bacteria involved in certain metabolic pathways have been observed in ICP. These findings suggest that alterations in the gut microbiome composition may contribute to the pathophysiology of ICP. Such microbiome-associated alterations may have important implications for risk stratification and early identification of patients at increased risk of adverse maternal and fetal outcomes. Further investigation into these microbial changes and molecular pathways could offer novel insights and identify potential pharmacological targets for ICP development and management. In particular, modulation of the gut microbiome could represent a future adjunctive strategy to existing therapeutic approaches, potentially improving disease monitoring and individualized management. The precise role of gut microbiome composition in the management and treatment of ICP is still not fully understood, highlighting the need for a systematic review to synthesize existing evidence and identify critical gaps relevant to the future development of screening, prevention, and targeted therapeutic strategies.\n\nID: 42384189\nTitle: Copper dysregulation in cardiometabolic disease: copper deficiency versus cuproptosis.\nAbstract: Copper is an essential micronutrient required for mitochondrial respiration, antioxidant defense, and metabolic homeostasis. Accumulating evidence demonstrates that dysregulated copper handling, including deficiency, redistribution, or overload, is a reproducible feature of multiple cardiometabolic disorders, including heart failure, diabetes mellitus, obesity, and NAFLD/MASLD. Human, animal, and cellular studies consistently implicate altered copper trafficking and compartmentalization in mitochondrial dysfunction, oxidative stress, and tissue remodeling across these conditions. The recent identification of cuproptosis, a copper-dependent form of regulated cell death characterized by mitochondrial copper binding to lipoylated tricarboxylic acid cycle enzymes, has expanded mechanistic understanding of copper toxicity in cancer. However, the defining molecular hallmarks of canonical cuproptosis, including lipoylated protein aggregation, iron-sulfur cluster loss, and respiration-dependent cell death, have not yet been demonstrated in vivo in cardiometabolic tissues. Accordingly, cuproptosis is discussed here as a testable mechanistic hypothesis rather than an established driver of cardiometabolic pathology. In this review, we synthesize current evidence for copper dysregulation in cardiometabolic disease and carefully distinguish established copper-dependent pathology from speculative cuproptotic mechanisms. We explicitly address the apparent paradox that the cardiac tissue context in cardiometabolic disease is dominated by a copper-deficient phenotype, which is the opposite of the mitochondrial copper-loading state required for canonical cuproptosis, and reconcile this through the concept of intracellular copper redistribution and tissue-selective susceptibility. We evaluate clinical and preclinical studies of copper-modulating therapies with attention to tissue specificity and safety, and we outline a framework for rigorously testing cuproptosis in vivo using convergent molecular, functional, and clinical criteria. Together, this review clarifies what is known about copper biology in metabolic disease and defines the experimental standards required to determine whether cuproptosis contributes to these conditions.\n\nID: 42381129\nTitle: Pharmacological Targeting of NRF2 Represents a Promising Therapeutic Approach for Pyroptosis-Related Non-Alcoholic Fatty Liver Disease.\nAbstract: Non-alcoholic fatty liver disease (NAFLD) is a clinicopathological condition characterized by the accumulation of fat within hepatocytes in the absence of excessive alcohol consumption or other identifiable causes of liver injury. As a disease involving complex pathogenic mechanisms, NAFLD has become the most prevalent chronic liver disease and may progress to more severe conditions. Pyroptosis is a pro-inflammatory form of programmed cell death that is distinct from classical apoptosis. Accumulating evidence suggests that pyroptosis plays a role in the pathogenesis of NAFLD, contributing to disease progression from simple hepatic steatosis to non-alcoholic steatohepatitis (NASH) and fibrosis. Excessive activation of pyroptosis can exacerbate inflammatory responses, induce cellular damage, disrupt immune homeostasis, and impair liver function. Therefore, elucidating the mechanisms and roles of pyroptosis in NAFLD is crucial for the development of effective therapeutic strategies. As a key transcription factor, nuclear factor erythroid 2-related factor 2 (NRF2) has emerged as a promising therapeutic target. Pharmacological modulation of NRF2 has shown potential in treating diseases characterized by oxidative stress and inflammation. Findings from in vitro and animal studies suggest that various compounds that target NRF2 to modulate pyroptosis exhibit notable effects on the initiation and progression of NAFLD. Although most of these agents are still in the early stages of preclinical research, they hold substantial promise for future clinical translation. This review outlines recent advances in pyroptosis-related research in NAFLD and highlights pharmacological targeting of NRF2 as a promising therapeutic approach for pyroptosis-mediated NAFLD.\n\nID: 42368425\nTitle: Ceramide-mediated mitochondrial dysfunction in nonobese nonalcoholic fatty liver disease: A regulatory role for serine palmitoyltransferase subunit 2.\nAbstract: This study investigated the pathological relevance of the serine palmitoyltransferase long chain base subunit 2 (Sptlc2)-ceramide axis in nonobese nonalcoholic fatty liver disease (NAFLD), focusing on hepatic steatosis, inflammation, oxidative stress, and mitochondrial dysfunction. A nonobese NAFLD rat model was established using a high-temperature dry-fried soybean diet. Integrated liquid chromatography-mass spectrometry-based proteomic and metabolomic analyses were used to identify candidate pathways. Sptlc2 function was validated by AAV2/8-mediated liver-directed knockdown in vivo, lentiviral knockdown in primary hepatocytes, and C2-ceramide rescue experiments. Multi-omics profiling identified Sptlc2 as a sphingolipid metabolism-related candidate in the model. Sptlc2 knockdown reduced long-chain ceramide accumulation, hepatic lipid deposition, inflammatory cytokine expression, oxidative stress, and hepatocyte injury. In primary hepatocytes, Sptlc2 silencing improved mitochondrial respiration, membrane potential, calcium and reactive oxygen species homeostasis, and mitochondrial ultrastructure. These protective effects were partially reversed by C2-ceramide in vitro and in vivo. The Sptlc2-ceramide axis contributes to ceramide accumulation, hepatic lipotoxicity, inflammatory activation, and mitochondrial dysfunction in this nonobese NAFLD model, suggesting its potential relevance as a therapeutic target for further investigation.\n\nID: 42337165\nTitle: Potential targets of baicalein in macrophages revealed by bulk and single cell RNA sequencing analysis.\nAbstract: Excessive inflammation drives organ dysfunction and high mortality in life-threatening conditions such as sepsis. Baicalein, a bioactive flavonoid, possesses well-recognized anti-inflammatory properties, yet its molecular targets in macrophages and potential systemic immunomodulatory effects on peripheral blood immune cells under hyperinflammatory conditions remain poorly characterized. Our previous studies demonstrated that baicalein alleviates hepatic inflammation in mice with non-alcoholic fatty liver disease (NAFLD) and inhibits NF-κB nuclear translocation in RAW264.7 macrophages. Here, by integrating network pharmacology, molecular docking, bulk RNA sequencing of macrophages, and single-cell RNA sequencing of peripheral blood from sepsis patients, we identified JAK2, SRC, TP53, MAPK3, AKT1, HSP90AA1, and ESR1 as potential core targets of baicalein in macrophages, and validated that the JAK2-STAT3 and NF-κB pathways might be the key downstream regulatory axes of its anti-inflammatory effects. Furthermore, we revealed that baicalein may modulate, based on single-cell expression signatures, the inflammatory phenotype of multiple peripheral blood immune cell populations, including monocytes, T cells, B cells, and granulocyte-monocyte progenitors, suggesting a potential systemic anti-inflammatory effect that requires experimental validation in human cells. Collectively, our findings elucidate the potential molecular targets of baicalein in macrophages and its multi-cellular immunoregulatory mechanisms under hyperinflammation, providing novel mechanistic insights for the clinical application of baicalein in inflammatory diseases.\n\nID: 42330767\nTitle: Integrating network pharmacology and in vivo evaluation reveals chicory (Cichorium intybus L.) extract activates autophagy to alleviate fatty liver hemorrhagic syndrome in laying hens.\nAbstract: Fatty liver hemorrhagic syndrome (FLHS) is a nutritional metabolic disease in poultry characterized by disrupted lipid metabolism in the liver. This study aimed to investigate the pharmacological effects and mechanisms of chicory (Cichorium intybus L.) root ethanol extract (CEE) on HELP-diet-induced FLHS. Seventy-two 50-week-old Hy-Line Brown laying hens were randomly allocated into three groups, with four replicates in each group and six hens per replicate. A standard basal diet was provided to the negative control (NC) group, whereas the other two groups were fed the high-energy low-protein (HELP) diet supplemented with 0 g/kg or 15 g/kg CEE, designated as the FLHS and CEE groups, respectively. The adaptation period lasted for 1 week, followed by a 12-week experimental period. UPLC-MS/MS-based component profiling of CEE, combined with network pharmacology analysis, identified three bioactive compounds: lactucopicrin, 2S,2'S-Aurantiamide acetate, and luteolin. Body weight was significantly increased by the HELP diet, while hens receiving CEE markedly lower body weight relative to the FLHS group at week 12 (P < 0.05 or 0.01). CEE supplementation significantly restored the laying rate, and reduced the Feed/egg ratio (P < 0.01). The FLHS group showed pronounced hepatic steatosis in laying hens, with increased TG and TC levels in serum and liver and elevated ALT and AST activities, which were markedly reversed by CEE treatment. There were 93 metabolites showing significant differences in the liver between the FLHS and CEE groups, such as 1-stearoyl-2-arachidoylglycerol, PE-NMe2, and 19-hydroxyarachidonic acid. Differentially expressed metabolites are enriched in the autophagy signaling pathway according to KEGG. CEE treatment significantly inhibited the protein levels of p-mTOR/mTOR, p62, Fasn, Acc, and Pparγ, while significantly increasing those of p-Ulk1/Ulk1, Atg5, LC3II/LC3I, and Pparα (P < 0.05 or 0.01). In conclusion, supplementation with 15 g/kg CEE effectively mitigated FLHS in laying hens by modulating hepatic lipid metabolism by activating autophagy. CEE represents a novel pharmacological strategy for FLHS treatment, highlighting chicory potential in poultry.\n\nID: 42322285\nTitle: Oxymatrine: Hepatoprotective Effects of a Multitarget Natural Alkaloid.\nAbstract: Liver diseases are a major global health burden with an occult onset and atypical symptoms, hindering early diagnosis. Herbal medicines feature low toxicity and multitarget effects; oxymatrine (OMT) from Sophora flavescens possesses anti-inflammatory, antioxidant, antiapoptotic, and antitumor activities, with prominent hepatoprotective effects. This systematic review explores the impact and molecular mechanisms of oxymatrine in managing various liver ailments, including liver injury, nonalcoholic fatty liver disease (NAFLD), liver fibrosis, and hepatocellular carcinoma (HCC), based on the findings from in vitro and in vivo studies. Using scientific databases such as PubMed, Web of Science, and Science Direct, studies were analyzed focusing on oxymatrine's pharmacological actions in liver disease. The search incorporated terms including \"oxymatrine,\" \"hepatoprotection,\" and \"liver disease.\" Oxymatrine mediates liver protection by modulating oxidative stress, suppressing inflammation, promoting lipid metabolism, and inhibiting fibrosis. Additionally, it exhibits tumor-suppressive effects through apoptosis induction and pathway modulation.\n\nID: 42299366\nTitle: Hepatogenomics of MAFLD in Asian Population: Genetic Polymorphisms and Pathway-Based Insights.\nAbstract: Metabolic dysfunction-associated fatty liver disease (MAFLD) has emerged as a major public health concern across Asia, marked by rising prevalence, younger age at presentation, and variability in clinical course. This variability reflects a complex interplay between metabolic exposures and genetic architecture, contributing to heterogeneity in disease susceptibility and progression. While dietary patterns, sedentary lifestyle, and metabolic comorbidities remain central contributors, inherited susceptibility influences hepatic fat accumulation, progression to steatohepatitis, and fibrotic transformation. This review aims to summarize genetic polymorphisms implicated in MAFLD among Asian populations and to explore their role in identifying individuals at increased inherited risk. A pathway-oriented perspective is adopted to contextualize how these variants contribute to key biological mechanisms underlying MAFLD. A narrative review approach was employed, drawing upon genome-wide association studies, candidate gene analyses, and functional research. Genetic variants were grouped into principal pathogenic pathways, including lipid handling, insulin resistance and de novo lipogenesis, cholesterol metabolism, inflammatory signaling, and fibrogenesis. While emphasis is placed on evidence from Asian cohorts, selected variants are also discussed based on mechanistic relevance, even when direct population-based data remain limited. Differences in allele frequency and effect size between Asian and Western populations were considered to clarify ethnic variation. Among the identified variants, PNPLA3 rs738409 consistently emerges as a dominant determinant of hepatic fat accumulation and adverse histological features. Additional polymorphisms further modulate risk, with some exerting protective effects. Taken together, current evidence supports integrating genetic markers into risk stratification models for earlier recognition of genetically predisposed individuals. This pathway-based synthesis provides a framework for understanding MAFLD heterogeneity in Asian populations and may inform precision-oriented prevention and individualized management.\n\nID: 42255694\nTitle: The Potential Alleviating Property Against NAFLD by Ganoderma lucidum With Bacteria-Enzyme Synergistic Fermentation.\nAbstract: Ganoderma lucidum is an edible and medicinal fungus. Triterpenoids, particularly ganoderic acids, represent the principal bioactive constituents in Ganoderma lucidum. Bacteria-enzyme synergistic fermentation broth of Ganoderma lucidum (FBG) was optimized as a potential alternative to traditional water-extracted Ganoderma lucidum (WEG). The optimized parameters with Lactobacillus rhamnosus fermentation exhibited the highest content of ganoderic acid F (GAF). Administration of FBG led to a pronounced decline in lipid deposition and contents of intracellular total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), reactive oxygen species (ROS), and malonic dialdehyde (MDA). The FBG treatment also markedly increased the activities of high-density lipoprotein cholesterol (HDL-C), superoxide dismutase (SOD), and catalase (CAT). The results of network pharmacology analysis and molecular docking suggested that GAF exhibits a robust interaction with the core targets sodium leak channel, nonselective (NALCN) and eukaryotic translation elongation factor 1 alpha 2 (EEF1A2). Enzyme-linked immunosorbent assay (ELISA) results demonstrated that GAF could effectively reduce lipid accumulation while upregulating EEF1A2, phosphorylated AMP-activated protein kinase (p-AMPK), and peroxisome proliferator-activated receptor alpha (PPAR-α) protein expression. Collectively, these findings indicate that GAF alleviates free fatty acid (FFA)-induced hepatic lipid accumulation through activation of the EEF1A2/p-AMPK/PPAR-α signaling pathway, suggesting a potential mechanism involving AMPK-related pathways.\n\nID: 42216291\nTitle: Adipose Tissue Inflammation, Oxidative Stress, and Altered Adipogenesis Are Associated With Dyslipidemia in Obesity: A Multiomics Profiling Study.\nAbstract: Obesity is an important risk factor for cardiometabolic disease, including dyslipidemia and atherosclerotic cardiovascular disease. Although the role of the liver in dyslipidemia is established, the contribution of adipose tissue is less clear. This study aims to clarify the role of adipose tissue in lipid metabolism and dyslipidemia. We conducted a cross-sectional analysis of 125 patients from the BARIA (The Immune System and Microbial Tone in Relation to NAFLD/NASH Before and After Bariatric Surgery in the Morbidly Obese in Amsterdam) longitudinal cohort study undergoing bariatric surgery. Comprehensive phenotyping included fasting untargeted plasma metabolomics, lipid, lipoprotein, adipokine profiling, RNA sequencing, and fecal shotgun metagenomics. Tissue transcriptomic and plasma metabolites were compared between individuals with and without dyslipidemia. Dyslipidemia was present in 43 of 125 individuals (34.4%), with higher triglycerides (1.62 versus 1.24 mmol/L), apoB (apolipoprotein B; 93.15 versus 81.81 mg/dL), and lower high-density lipoprotein (1.02 versus 1.35 mmol/L) and apoAI (136.40 versus 161.35 mg/dL). Plasma adipokines showed limited differences: leptin concentrations were lower in dyslipidemia in unadjusted analysis but reduced after adjustment for age, sex, and body weight (adjusted P=0.057). RNA sequencing identified altered gene expression of liver, jejunum, visceral and subcutaneous adipose tissue, most pronounced in subcutaneous adipose tissue. Dyslipidemia was associated with adipose tissue pathways related to inflammation, oxidative stress, and adipogenesis. Plasma metabolomics revealed associations with endocannabinoid-like, secondary bile acid, plasmalogen, butyrate, and sphingolipid metabolites. Gut metagenome analysis found modest differences. Dyslipidemia in obesity is associated with transcriptomic alterations in adipose tissue, including subcutaneous adipose tissue, involving inflammation, oxidative stress, and adipogenesis. These findings support a role of adipose tissue in lipid regulation beyond hepatic pathways.\n\nID: 42208803\nTitle: Maximization of mitochondrial fatty acid oxidation by co-administration of PPARα agonist and peroxisomal β-oxidation inhibitor.\nAbstract: PPARα plays a pivotal role in regulating hepatic fatty acid oxidation and activation of PPARα has been well known to stimulate mitochondrial β-oxidation and has the potential to reduce hepatic lipid level, while evidences indicate that administration of PPARα agonist does not affect hepatic triglyceride level. Therefore, an alternative mechanism might work to counteract the lipid-lowering effect of PPARα agonist. As fatty acids can also be metabolized in peroxisome and the acetyl-CoA generated in peroxisomal β-oxidation could be used for the biosynthesis of malonyl-CoA, a critical molecule in controlling mitochondria fatty acid oxidation. We hypothesize that peroxisomal β-oxidation might play a role in regulating mitochondrial fatty acid oxidation through mediating malonyl-CoA formation. This study demonstrates a counteracting mechanism by which induction of peroxisomal β-oxidation causes suppression of mitochondrial fatty acid oxidation in animals administered with PPARα agonist. PPARα agonist induces oxidation of fatty acids by peroxisomes and generates considerable acetate in the liver, which significantly elevates hepatic content of malonyl-CoA, and causes suppression of mitochondrial β-oxidation. Specific inhibition of peroxisomal β-oxidation enhances mitochondrial fatty acid oxidation and attenuates hepatic lipid accumulation by reducing acetate and malonyl-CoA formation in the mice treated with PPARα agonist. It is suggested that combination therapy of PPARα agonist and peroxisomal β-oxidation inhibitor might be a novel and effective treatment of fatty liver and related metabolic disorder through maximization of mitochondrial fatty acid oxidation.\n\nID: 42196377\nTitle: Integrated Network Pharmacology and Gut Microbiota Analysis Reveals the Alcoholic Extract of Anacyclus pyrethrum Root Prevents Nonalcoholic Fatty Liver Disease via the LPS/TLR4/NF-κB Pathway.\nAbstract: The global incidence of nonalcoholic fatty liver disease (NAFLD) is rising, with no approved pharmacotherapy available. Medicinal plants offer a potential preventive strategy. Anacyclus pyrethrum root exhibits anti-inflammatory and glucose-regulating properties, but its role in NAFLD prevention is unclear. This study aims to investigate the preventive effect of Anacyclus pyrethrum root ethanol extract (APE) against NAFLD and its underlying mechanisms. The chemical composition of APE was analyzed by UHPLC-HRMS. Network pharmacology predicted the potential signaling pathways underlying its protective effects against NAFLD. In a 12-week high-fat diet mice model, APE treatment led to measurements of blood glucose, lipid profiles, liver function parameters, histopathological changes in liver and colon, and gut microbiota alterations via 16S rDNA sequencing. In animal experiments, APE lowered fasting and random blood glucose, total cholesterol, triglycerides, LDL-C, AST, ALT, and serum lipopolysaccharide while increasing HDL-C, and alleviated hepatic steatosis. Network pharmacology suggested APE acts via TLR, NF-κB, and TNF pathways. In vivo, APE suppressed hepatic TLR4, MyD88, p-NF-κB p65, the p-NF-κB p65/NF-κB p65 ratio, and TNF-α/IL-6 levels. Gut microbiota analysis showed increased Akkermansiaceae and decreased Desulfovibrionaceae. APE also upregulated intestinal Occludin and ZO-1, and downregulated intestinal TNF-α and IL-6. APE prevents NAFLD progression, potentially by regulating gut microbiota, protecting the intestinal mucosal barrier, and inhibiting the LPS/TLR4/MyD88/NF-κB pathway.\n\nID: 42196250\nTitle: Integrative Multi-Omics Reveal Silibinin Alleviates Heat Stress-Driven Hepatic Lipid Disruption in Laying Hens.\nAbstract: Heat stress (HS) has emerged as a major environmental stressor, inducing oxidative stress and hepatic steatosis and impairing production performance and health in laying hens, with limited evidence-based nutritional interventions available. This study investigated the hepatoprotective effects of dietary silibinin (SIL) against chronic HS. In a 10-week trial, 252 43-week-old Hy-Line Brown hens were exposed to daily HS (32 ± 1 °C, temperature-humidity index [THI] > 73) and fed either a basal diet or one supplemented with 100 mg/kg SIL. SIL significantly increased laying rate (p < 0.05) and improved albumen height, Haugh units, and shell strength by week 8 (p < 0.05). Histological analysis showed a 48% reduction in non-alcoholic fatty liver disease (NAFLD) activity score, with significantly decreased hepatic triglyceride content (p < 0.05); Oil Red O staining confirmed reduced lipid droplet accumulation. SIL restored redox balance by increasing plasma, hepatic total superoxide dismutase (T-SOD), and glutathione peroxidase (GSH-Px) (p < 0.05), increasing hepatic catalase (CAT) and glutathione (GSH) levels while decreasing malondialdehyde (MDA) (p < 0.05). Untargeted plasma metabolomics identified 11 key metabolites related to 2-oxoglutarate and purine metabolism, while hepatic transcriptomics revealed 835 differentially expressed genes primarily in the PPAR signaling and fatty acid biosynthesis pathways. SIL suppressed de novo lipogenesis via downregulation of ACACA and FASN, and enhanced β-oxidation through upregulation of CPT1A and ACSL1 (p < 0.05). Molecular docking indicated favorable binding affinities between SIL and these targets, which was further supported by corresponding changes in protein expression via Western blotting. Correlation analysis revealed a consistent alignment between the upregulation of ACSL1/CPT1A and improvement in performance and antioxidant status, suggesting a coordinated metabolic shift. These findings emphasize the potential of SIL as a sustainable animal nutrition antioxidant additive, which can alleviate HS-induced lipid disorders in the liver of laying hens. Importantly, these hepatoprotective effects were demonstrated exclusively under chronic heat stress conditions; further studies incorporating a normothermic baseline are required to distinguish stress-specific mitigation from general metabolic stimulation.\n\nID: 42196216\nTitle: Experimental Models of Metabolic Dysfunction-Associated Steatotic Liver Disease: A Comparative Analysis of a Choline-Deficient and Cholesterol-Enriched Diet in Rats.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a widespread pathology requiring adequate preclinical models for studying pathogenesis and evaluating therapeutic and preventive agents. This study compared differential markers of MASLD pathogenesis in rats using two distinct dietary models: a choline-deficient high-fat diet (HFD-CD) and a cholesterol-enriched high-fat diet (HFD+CHOL). Male Wistar rats were fed either a control AIN93M diet, HFD-CD (40% fat, 20% fructose, and choline deficiency), or HFD+CHOL (40% fat, 20% fructose, and 1% cholesterol) for 56 days. Comprehensive assessment included phenotypic, biochemical, hematological, histomorphological parameters, oxidative stress markers, hepatocyte apoptosis, cytokine levels, and hepatic gene expression. HFD-CD induced steatosis with moderate insulin resistance, increased malondialdehyde levels, and suppressed Acaca, Scd and ChREBP gene expression. In contrast, HFD+CHOL caused macrovesicular steatosis, inflammation, early fibrosis, atherogenic dyslipidemia, intrahepatic cholesterol accumulation, hepatocyte apoptosis, upregulated Srebf1, Cyp7a1, and Nfkb1 expression, and activated Nrf2-dependent antioxidant responses. HFD-CD and HFD+CHOL induce two pathogenetically distinct MASLD phenotypes. The HFD-CD model, characterized by steatosis and oxidative stress without pronounced inflammation or fibrosis, is preferable for studying the preventive potential of bioactive food compounds. Conversely, the HFD+CHOL model with inflammatory and fibrotic components is more suitable for evaluating therapeutic agents aimed at mitigating inflammation, restoring cholesterol homeostasis, and attenuating fibrosis.\n\nID: 42184637\nTitle: Effects of modified corn straw dietary fiber on antioxidant status, gut health and lipid metabolism in broilers fed a high-fat diet.\nAbstract: Hepatic abnormal fat accumulation may induce metabolic dysfunction, whereas dietary fiber is proven to reduce body fat deposition. Corn straws, rich in lignocellulose, are a potential source of dietary fiber. This study explored the effects of modified corn straw dietary fiber (MCDF) on broilers fed a high-fat diet and its regulatory mechanisms in lipid metabolic disorders. A total of 150 one-day-old Arbor Acres (AA) broilers were randomly assigned to three experimental groups: control group (basal diet), group 1 (high-fat diet), and group 2 (high-fat diet supplemented with 1% MCDF). The feeding trial was divided into two phases: the early stage (1 to 21d) and the later stage (22 to 42 d). Results showed that groups 1 and 2 exhibited significantly higher ADG and ether extract (EE) metabolism rate at 21 d compared to control group (P < 0.01), whereas feed/gain (F/G) and CP metabolism rate were reduced (P < 0.01). At 42 d, group 2 exhibited a lower F/G compared to the other groups (P < 0.001). MCDF decreased serum levels of TC, TG, ALP, and MDA (P < 0.05), whereas elevated the serum levels of CAT, GSH-Px, IgA, and IgM (P < 0.05). Multi-omics analysis revealed that MCDF reshaped the gut microbiota by increasing the abundance of beneficial taxa (Bacteroidota and Bacteroides) and reducing potentially harmful bacteria (Campylobacterota). These microbial changes were associated with alterations in serum metabolites (arachidonic acid, DHA, DPA, EPA). Furthermore, changes in these metabolites were involved in the regulation of hepatic lipid metabolism by modulating cytochrome P450-related pathways, amino acid metabolism, and key regulatory genes including CYP450, CYP7A1, LTC4S, and PPARα. In conclusion, MCDF alleviated high-fat diet-induced hepatic lipid metabolic disorders through the gut microbiota-metabolite-liver axis. These findings suggest that MCDF, as a functional dietary fiber, has potential applications for improving metabolic health in broilers.\n\nID: 42171826\nTitle: Emerging roles of combined curcumin and berberine in disease modulation: a comprehensive review of mechanisms and therapeutic relevance.\nAbstract: Curcumin, a polyphenolic compound derived from Curcuma longa, and berberine, an isoquinoline alkaloid extracted from plants such as Coptis chinensis, exhibit multifaceted pharmacological properties, including potent antioxidant, anti-inflammatory, antimicrobial, and anticancer effects. This narrative review evaluates their therapeutic potential across a diverse range of conditions, including nonalcoholic fatty liver disease (NAFLD), various malignancies, wound and plant infections, Alzheimer's disease, cardiovascular disorders, irritable bowel syndrome, cyclophosphamide-induced toxicity, interstitial cystitis, and systemic lupus erythematosus. Mechanistically, curcumin and berberine modulate gut microbiota, suppress lipogenic and inflammatory pathways (e.g., SREBP-1c and NF-κB), and activate PI3K/Akt and PPARγ signaling, thereby reducing hepatic steatosis and inflammation. Furthermore, they induce apoptosis, inhibit the PI3K/Akt/mTOR pathway, and modulate the tumor microenvironment, with their enhanced combined effects being significantly amplified by nanodelivery systems, such as liposomes. Their antimicrobial efficacy targets methicillin-resistant Staphylococcus aureus (MRSA) and plant pathogens by disrupting biofilms and generating reactive oxygen species via nanofibers and self-assembled submicron particles. Moreover, they reduce amyloid-beta aggregation, promote autophagy, and mitigate neuroinflammation. Additionally, their immunomodulatory properties effectively suppress autoimmune responses. Ultimately, this review synthesizes the current evidence regarding the therapeutic versatility of curcumin and berberine across multiple pathologies.\n\nID: 42164255\nTitle: Chlorogenic acid modulates gut microbiota and metabolites to alleviate intrahepatic cholestasis of pregnancy: Insights from 16S rRNA sequencing and metabolomics.\nAbstract: Intrahepatic cholestasis of pregnancy (ICP) is a liver disorder marked by impaired bile flow, elevated serum bile acids, and pruritus, posing significant risks to maternal and fetal health. Current treatments, including ursodeoxycholic acid, have shown limited efficacy, underscoring the need for more effective therapies. Chlorogenic acid (CGA), a polyphenolic compound with antioxidant, anti-inflammatory, and hepatoprotective properties, has shown promise in managing liver diseases, but its role in ICP remains poorly understood. This study investigated the therapeutic effects of CGA in a rat model of ICP induced by 17α-ethinylestradiol. CGA treatment significantly reduced liver enzyme levels, total bile acids, and bilirubin, while improving histopathological liver damage. CGA also modulated key proteins involved in bile acid synthesis and transport, including FXR, CYP7A1, NTCP, and BSEP. Additionally, CGA treatment improved intestinal barrier function by upregulating tight junction proteins, including ZO-1. Metabolomics and 16S rRNA gene sequencing revealed that CGA treatment restored gut microbiota balance in ICP rats. CGA demonstrated a dose-dependent response, with higher doses providing more pronounced therapeutic effects. These findings suggest that CGA alleviates ICP by regulating bile acid metabolism, improving liver function, and modulating the gut microbiome, highlighting its potential as an effective therapeutic option for managing ICP.\n\nID: 42154845\nTitle: AEROBIC EXERCISE ATTENUATES HEPATIC LIPID PEROXIDATION IN AN EXPERIMENTAL MODEL OF OBESITY-ASSOCIATED NAFLD.\nAbstract: The global rise in obesity has been accompanied by an increasing prevalence of nonalcoholic fatty liver disease (NAFLD), for which effective non-pharmacological therapeutic strategies remain limited. This study investigated the effects of aerobic exercise on hepatic oxidative stress in an experimental model of obesity-associated NAFLD. Newly weaned Wistar rats were fed a highly palatable, obesity-inducing diet. After obesity was established, the animals were randomly assigned to either a trained group (n=12) or a sedentary group (n=12). The trained group underwent moderate-intensity treadmill running for eight weeks. Hepatic lipid peroxidation was assessed using the TBARS (thiobarbituric acid reactive substances) assay. Aerobic training significantly reduced hepatic TBARS levels (P<0.0005), in an average of 1.8 nmol MDA/mg protein compared to the sedentary group. These benefits were significant regardless of weight gain maintenance. The findings suggest that regular physical exercise attenuates hepatic lipid peroxidation in an experimental model of obesity-associated NAFLD. The results support that physical exercise is an effective non-pharmacological strategy for modulating oxidative stress and preventing disease progression. O aumento global da obesidade tem sido acompanhado de prevalência crescente da doença hepática gordurosa não alcoólica (DHGNA), para a qual ainda são limitadas estratégias terapêuticas não farmacológicas eficazes. Este estudo investigou os efeitos do exercício aeróbico sobre o estresse oxidativo hepático em um modelo experimental de obesidade associada à DHGNA. Ratos Wistar recém-desmamados foram alimentados com dieta altamente palatável e indutora de obesidade. Após o estabelecimento da obesidade, os animais foram divididos aleatoriamente em grupos treinados (n=12) e sedentários (n=12). O grupo treinado foi submetido à corrida em esteira de intensidade moderada por oito semanas. A peroxidação lipídica hepática foi avaliada por meio do método TBARS (substâncias reativas ao ácido tiobarbitúrico). O treinamento aeróbico reduziu significativamente os níveis hepáticos de TBARS (P<0,0005), em uma média de 1,8 nmol MDA/mg de proteína em comparação ao grupo sedentário. Esses benefícios foram evidentes, apesar da manutenção do ganho de peso. Os achados sugerem que o exercício físico regular atenua a peroxidação lipídica hepática em modelo experimental de DHGNA associada à obesidade. Os resultados indicam que o exercício físico é uma estratégia não farmacológica eficiente na modulação do estresse oxidativo e na prevenção da progressão da doença.\n\nID: 42126781\nTitle: Bisphosphoglycerate mutase is involved in glucose metabolism and progression of nonalcoholic fatty liver disease based on liver organoids.\nAbstract: This study seeks to investigate the underlying mechanism of glycolytic key gene bisphosphoglycerate mutase (BPGM) in nonalcoholic fatty liver disease (NAFLD). qRT-PCR and immunohistochemistry were utilized to detect BPGM levels in clinical NAFLD samples. HepG2 cells and liver organoids were treated with free fatty acid. (FFA). The role of BPGM in NAFLD was explored at cellular, organoid, and animal levels. Metabolomics was performed to analyze differential metabolites and metabolic pathways. Furthermore, we examined the regulatory mechanisms of BPGM by HIF-1α in NAFLD. Results indicated that high expression of BPGM in NAFLD samples was correlated with NAFLD progression. Moreover, Severe group had higher BPGM expression than Mild group. FFA treatment induced time-dependent steatosis and BPGM upregulation in HepG2 cells and liver organoids, whereas BPGM knockdown attenuated lipid accumulation, cellular injury, and oxidative stress. At the animal level, knockdown of BPGM reversed high-fat diet (HFD) induced lipid accumulation and liver tissue injury. Metabolomics studies showed significant changes of metabolic pathways including glycolysis/gluconeogenesis and pyruvate metabolism. Verification experiment showed FFA increased pyruvic acid levels, and knockdown of BPGM decreased pyruvic acid levels. Pyruvic acid further reversed the changes in NAFLD progression caused by BPGM knockdown at the cellular and organoid levels. Finally, HIF-1α regulated the expression of BPGM in NAFLD. Together, our findings suggest that BPGM contributes to abnormal glucose metabolism and promotes hepatic steatosis, thereby driving NAFLD progression.\n\nID: 42114284\nTitle: Functional effects of rosmarinic acid on gut health and epigenetic regulation in antibiotic-free poultry diets.\nAbstract: Rosmarinic acid (RA), a bioactive polyphenol found in Salvia officinalis and other Lamiaceae herbs, has attracted attention for its functional feed application in animal nutrition. RA supplementation positively influences growth efficiency, liver antioxidant status, and serum biochemical indices in broilers. Its antimicrobial and immunomodulatory effects promote health and productivity. Studies suggest benefits for gut health and meat quality; however, epigenetic regulation of RA in poultry is considered a minor future perspective, being mostly based on mammalian studies. Hypothesized impacts of RA on chronic disease prevention and as a microbiome-engineering agent require further investigation. This review explores the regulatory effects of RA on DNA methylation, non-coding RNAs (ncRNAs), and histone modifications, which influence gut microbiome structure, nutrient absorption, and immune function in poultry. It emphasizes RA's potential as a functional food for gastrointestinal health, metabolic regulation, and chronic disease prevention, alongside its use in antibiotic-free poultry feed for microbiome engineering. The review also discusses RA's effects on lipid metabolism and oxidative stress, highlighting its role in maintaining intestinal barrier health. Nevertheless, certain limitations must be acknowledged, as successful nutritional interventions depend on understanding individual variability, including genetics, metabolism, age, and health status. Tailored methodologies, such as micronutrition and genomic nutrition, can improve diet quality, promote nutrient absorption, and enhance overall animal health. A tailored feeding regimen focuses on selecting nutrients with proven benefits for key health outcomes, such as omega-3 fatty acids, which scientific evidence shows promote brain and heart health while reducing inflammation.\n\nID: 42110460\nTitle: The oral-gut-liver axis: linking periodontal microbiota to the pathogenesis of liver diseases.\nAbstract: Oral microbiota plays a critical role in linking oral and systemic health, with dysbiosis closely associated with the onset and progression of chronic liver diseases. This review systematically examines the central role of the \"oral-gut-liver axis\" in hepatic pathophysiology. Epidemiological evidence has identified periodontitis and specific oral pathogens, such as Fusobacterium nucleatum (F. nucleatum), as independent risk factors for the progression of non-alcoholic fatty liver disease (NAFLD), development of cirrhosis, and incidence of hepatocellular carcinoma (HCC). The underlying mechanisms primarily involve four interrelated pathways: (1) direct bacterial translocation, where pathogens such as F. nucleatum colonize the liver via bacteremia and activate oncogenic pathways; (2) systemic dissemination of bacterial metabolites, such as lipopolysaccharides (LPS), driving hepatic inflammation, oxidative stress, and fibrosis via Toll-like receptor 4 (TLR4) signaling and reactive oxygen species (ROS)-mediated pathways; (3) systemic immune inflammation, wherein periodontitis acts as a chronic inflammatory focus that continuously releases pro-inflammatory mediators into the circulation; and (4) indirect effects mediated by gut microbiota dysbiosis, whereby oral bacteria compromise the intestinal barrier, facilitating the influx of gut-derived toxins into the liver. These findings underscore the significant impact of oral health on hepatic status. In the short term, oral microbial profiles represent promising noninvasive diagnostic and prognostic biomarkers. Preliminary clinical trials indicate that periodontal therapy can improve metabolic parameters in patients with NAFLD. In the long term, promoting interdisciplinary collaboration between hepatology and oral medicine and strategically integrating oral health interventions into the comprehensive management framework for liver diseases hold significant public health potential for mitigating the global burden of hepatic disorders.\n\nID: 42425686\nTitle: Microbiota-liver axis and host transcriptomic mechanisms underlying the anti-obesity effects of Bifidobacterium animalis DPU-MWFBA in early-life overfeeding.\nAbstract: Early-life nutritional overfeeding is increasingly recognized as a critical driver of metabolic programming and long-term obesity risk. This study investigated the protective effects and underlying mechanisms of Bifidobacterium animalis DPU-MWFBA, designated as FBA-40, against early-life overfeeding-induced obesity and metabolic dysfunction. An early overfeeding mouse model was established by small-litter rearing, followed by a two-week oral intervention with FBA-40. FBA-40 significantly attenuated excessive body weight gain and adiposity, improved glucose tolerance and insulin sensitivity, and alleviated dyslipidemia, systemic inflammation, and hepatic dysfunction. Histological analyses showed that FBA-40 reduced hepatic lipid accumulation and improved liver morphology. In addition, colonic histology and immunohistochemistry demonstrated that FBA-40 preserved intestinal barrier integrity by increasing ZO-1 and Occludin expression while suppressing TNF-α-associated inflammatory activation. Gut microbiota analysis revealed that FBA-40 restored microbial richness and diversity and reshaped gut microbial composition toward a more metabolically favorable profile. Hepatic transcriptomic analysis further showed that FBA-40 reprogrammed lipid metabolism-, oxidative stress-, and inflammation-related pathways, particularly PPAR signaling, linoleic acid metabolism, cholesterol metabolism, bile secretion, and arachidonic acid metabolism. qRT-PCR and estern blot validation confirmed that FBA-40 suppressed lipogenesis-related targets, including Scd1, Acaca, Lpin1, and SCD1, while restoring PPARα/EHHADH-associated fatty acid β-oxidation and GPX1-mediated antioxidant defense. Collectively, these findings demonstrate that FBA-40 alleviates early-life overfeeding-induced metabolic dysfunction by coordinating gut microbial remodeling, intestinal barrier protection, and hepatic lipid metabolic reprogramming. This study provides mechanistic evidence supporting FBA-40 as a promising early-life probiotic candidate for preventing obesity and associated metabolic disorders.\n\nID: 42419122\nTitle: Discovery of cis-Gnetin H from peony seed coat as a potent antifibrotic agent modulating hepatic fibro-inflammatory pathways and gut microbiota homeostasis.\nAbstract: Liver fibrosis is a reversible stage of chronic liver disease lacking effective therapies. The peony seed coat, a major byproduct of peony oil production, is rich in bioactive stilbenes. However, its anti-fibrotic potential and underlying mechanisms remain systematically unexplored. This study aimed to isolate stilbenes from peony seed coat, identify the potent anti-fibrotic compounds, and evaluate their anti-fibrotic activity and mechanisms of action. A structure-oriented separation strategy, guided by spectroscopic analysis, enabled the isolation of stilbenes. Anti-fibrotic activity was screened in TGF-β1-induced hepatic stellate cells (HSCs). In vivo efficacy was evaluated in a CCl₄-induced mouse liver fibrosis model. Mechanisms were investigated using transcriptomics, Western blotting, and 16S rRNA gene sequencing. Among seven isolated stilbenes, cis-Gnetin H exhibited the most potent inhibition of HSCs activation by downregulating α-SMA, Collagen I, and Smad3. In CCl₄-treated mice, cis-Gnetin H significantly ameliorated liver injury, inflammation, and fibrosis. Mechanistically, cis-Gnetin H activated the Nrf2/HO-1 antioxidant pathway while suppressing NF-κB and TGF-β1/Smad signaling. Furthermore, cis-Gnetin H remodeled the gut microbiota by enriching beneficial genera and reducing pathogenic Staphylococcus. This microbial modulation was accompanied by increased production of SCFAs, which correlated strongly with improved hepatic parameters. cis-Gnetin H acts as an anti-fibrotic agent through modulating hepatic inflammatory and fibrotic signaling, and regulating the gut-liver axis via microbiota restoration and metabolite enhancement. These findings highlight cis-Gnetin H as a promising therapeutic candidate and support the high-value utilization of peony agricultural byproducts.\n\nID: 42382178\nTitle: Mangiferin alleviates metabolic-associated fatty liver disease by modulating gut microbiota and FXR signaling pathway to regulate bile acid metabolism.\nAbstract: Metabolic-associated fatty liver disease (MAFLD) is characterized by excessive hepatic lipid accumulation, with limited safe and effective therapeutic options currently available. Previous studies have demonstrated that mangiferin (MAN) alleviates nonalcoholic fatty liver disease via modulation of the AMPK and NLRP3 signaling pathways. However, there are no reports to date investigating whether MAN exerts anti-MAFLD effects by regulating bile acid (BAs) metabolism and its underlying molecular mechanisms. In the present study, the anti-MAFLD effects of MAN were systematically investigated using a high-fat diet (HFD)-induced MAFLD mouse model. We evaluated the therapeutic mechanisms of MAN specifically from the perspectives of BAs metabolism regulated by the farnesoid X receptor (FXR) signaling pathway and the modulation of the gut microbiota, utilizing 16S rRNA sequencing and molecular docking analyses. MAN treatment (100 mg/kg) significantly ameliorated glucose and lipid metabolic disorders, as well as hepatic lipid accumulation in the HFD-induced MAFLD mice, which was accompanied by marked alterations in the BAs metabolic profile. Mechanistically, MAN activated the FXR signaling pathway, and molecular docking analysis predicted stable interactions with key FXR residues (Y365, M369, and Y373). Furthermore, 16S rRNA sequencing revealed that MAN significantly decreased the relative abundance of Lactobacillus and Limosilactobacillus, which were positively correlated with abnormal BAs (including 6,7-DKLCA, ILCA, GHDCA, and GUDCA), dyslipidemia, and liver injury markers. In contrast, MAN increased the relative abundance of Faecalibaculum, which was negatively correlated with these BAs and associated with an improved metabolic status. MAN exerts anti-MAFLD effects through dual mechanisms: direct activation of the FXR signaling pathway to regulate BAs homeostasis and indirect modulation of the gut microbiota to influence BAs metabolism. These findings highlight the therapeutic potential of MAN and provide new insights into natural product-based strategies for MAFLD treatment.\n\nID: 42356391\nTitle: Ketogenic Diet in Obesity and Diabetes: A Narrative Review.\nAbstract: A ketogenic diet (KD) is a low-carbohydrate, high-fat dietary approach. Beyond treating neurologic disorders, KDs have attracted significant media attention for their potential to improve obesity and diabetes. The diet induces a metabolic shift from glucose toward fatty acid oxidation and ketone body production. This shift leads to ketosis, which may reduce hunger, partly through the anorexigenic effects of ketone bodies, thereby contributing to weight loss and improved metabolic parameters, including glycaemic control and insulin sensitivity. In particular, the positive effects of KDs lower insulin demand and may thereby improve β-cell function. However, the long-term efficacy, safety, and sustainability of KDs, especially for diabetes, remain debated. This review offers current insights into the effects of ketogenesis and ketosis, as well as the potential mechanisms underlying them. We explore the metabolic effects of KDs in obesity and diabetes, drawing on preclinical and clinical studies, and suggest that combining KDs with antidiabetic agents may provide synergistic benefits. However, combining KDs with these pharmacotherapies, particularly SGLT-2 inhibitors, requires careful clinical supervision because of potential risks, including euglycaemic diabetic ketoacidosis. We explore how a KD alters the composition of the gut microbiota, thereby affecting host health. We conclude by highlighting challenges and future directions for optimising KD-based therapies and by outlining the limitations of the current review.\n\nID: 42330761\nTitle: Integrating 16S rRNA gene sequencing and transcriptomics to investigate the hepatoprotective effects of compound Ilicis Rotundae Cortex against lipopolysaccharide / enrofloxacin-induced liver injury in chicks.\nAbstract: Compound Ilicis Rotundae Cortex (CIRC) has been demonstrated to ameliorate E. coli-induced liver injury. However, its efficacy and regulatory mechanisms against liver injury in chicks remain unclear. In this study, a chick liver injury model was established using lipopolysaccharide (LPS) and enrofloxacin (ENR) to investigate the effects of CIRC. The results showed that dietary supplementation with 3 ‰ CIRC significantly prevented liver injury, restored growth performance, and alleviated inflammation and oxidative stress in the injured chicks. Integrated analysis of 16S rRNA gene sequencing and hepatic transcriptomics revealed a gut-liver axis-mediated mechanism for the hepatoprotective effect of CIRC. By modulating the gut microbiota, enhancing intestinal barrier function, and enriching butyrate-producing bacteria, CIRC increased butyric acid (BA) levels in both serum and liver tissue, alleviated the LPS/ENR-induced suppression of the hepatic butanoate metabolism pathway, and subsequently regulated the IL-17, Toll-like receptor, and NF-κB signaling pathways, collectively exerting a hepatoprotective effect. In conclusion, CIRC plays a crucial role in preventing chick liver injury by modulating the gut microbiota.\n\nID: 42310552\nTitle: Integrative multi-omics analysis reveals a gut-liver axis signature of metabolic reprogramming associated with response to transarterial chemoembolization in hepatocellular carcinoma.\nAbstract: Transarterial chemoembolization (TACE) is a standard treatment for intermediate-stage hepatocellular carcinoma (HCC), but response is highly variable. The systemic metabolic impact of TACE and its connection to tumor-intrinsic factors governing efficacy remain poorly understood. We hypothesized that by comparing host fecal metabolomics with tumor transcriptomics, we could identify convergent pathways suggestive of a gut-liver axis signature of TACE response. We performed untargeted fecal metabolomics in a prospective paired cohort of 30 HCC patients sampled before TACE and again on post-TACE day 4, an early time point selected to capture acute ischemic, inflammatory, and metabolic perturbations after embolization. To characterize tumor-intrinsic programs associated with efficacy, we analyzed the independent public transcriptomic dataset GSE104580 containing pre-treatment tumors from TACE responders and non-responders. Cross-cohort integration was conducted at the pathway level to identify convergent biological themes. For metabolomics, paired univariate testing with Benjamini-Hochberg false discovery rate (FDR) correction and Variable Importance in Projection (VIP) > 1 from PLS-DA were used; for transcriptomics, differential expression used adjusted p < 0.05 and |log2FC|> 1, followed by GSEA. TACE induced a shift in the fecal metabolome, with significant enrichment of glycerophospholipid metabolism, together with changes in bile acid-related metabolites and tryptophan/vitamin B6-related metabolites. Lysophosphatidylcholines (LysoPCs), including LysoPC (22:4), and bile acid-related metabolites were increased after TACE, consistent with acute treatment-associated tissue metabolic perturbation. Independent transcriptomic analysis revealed that responder tumors were enriched for primary bile acid biosynthesis, fatty acid degradation, and tryptophan metabolism, with higher expression of CYP7A1, ACOX1, IDO1, and TDO2, whereas non-responders were enriched for Cell cycle, DNA replication, and ribosome-related programs. Because the metabolomics and transcriptomics datasets were derived from separate cohorts, these convergent findings support a pathway-level cross-cohort model rather than direct patient-level tumor-fecal linkage. Our comparative analysis suggests a potential gut-liver axis signature associated with TACE efficacy. We therefore present fecal LysoPC as a candidate non-invasive pharmacodynamic readout of acute post-TACE tissue injury and host-microenvironmental perturbation rather than a tumor-necrosis-specific biomarker. Likewise, the convergence on bile acid and tryptophan metabolism suggests that a responder-associated tumor metabolic phenotype may be relevant to TACE sensitivity. These findings offer potential non-invasive biomarkers and highlight new therapeutic targets to enhance TACE efficacy.\n\nID: 42298689\nTitle: Dachaihu decoction alleviates septic liver injury by modulating the intestinal barrier dysfunction and suppressing the NF-κB/NLRP3/Caspase-1 signaling pathway.\nAbstract: Intestinal barrier dysfunction is a key driver of septic liver injury (SLI). Dachaihu decoction (DCHD), a classic traditional Chinese medicine formula recorded in the Treatise on Cold Damage, is widely used to treat gastrointestinal and hepatic inflammatory conditions. The primary objective of our research was to elucidate the protective effects of DCHD against SLI and the underlying molecular mechanisms. In a murine model of sepsis induced by cecal ligation and puncture (CLP), we evaluated the therapeutic effects of DCHD on SLI by assessing serum liver enzymes, histopathology, oxidative stress, hepatocyte apoptosis, and inflammatory cytokines. Intestinal barrier integrity was examined via transmission electron microscopy, serum biomarkers (D-lactate, DAO, LPS), and tight junction proteins (ZO-1, Occludin, E-cadherin). Gut microbiota composition was analyzed using 16S rRNA sequencing. Chemical profiling of DCHD was performed via UPLC-Q-TOF-MS. Integrated network pharmacology, bioinformatics, and transcriptomic analyses identified the NF-κB/NLRP3/Caspase-1 axis as a potential mechanism, which was validated in vivo and in LPS-stimulated immortalized mouse Kupffer cells (ImKCs). Functional involvement of TLR4 and NLRP3 was further confirmed by genetic silencing of TLR4 with siRNA and pharmacological inhibition using TAK-242 (TLR4 inhibitor) and MCC950 (NLRP3 inhibitor). DCHD treatment attenuated liver injury in CLP-induced septic mice, as evidenced by improved liver function, attenuated histopathology, reduced oxidative stress, suppressed inflammation, and decreased hepatocyte apoptosis. These hepatoprotective effects were associated with reduced intestinal permeability and enhanced barrier integrity, alongside gut microbiota remodeling characterized by enrichment of beneficial bacteria and reduced abundance of gram-negative genera (e.g., Klebsiella, Enterobacter, Proteus), leading to decreased LPS production and translocation to the liver. Integrated network pharmacology and transcriptomics revealed the NF-κB/NLRP3/Caspase-1 axis as a central mechanism, with DCHD downregulating p-p65, p-IκBα, NLRP3, ASC, and Cleaved Caspase-1 in vivo and in LPS-stimulated ImKCs. Functional validation using TLR4 siRNA and the inhibitors TAK-242 and MCC950 confirmed that DCHD might attenuate liver inflammatory injury primarily through the NF-κB/NLRP3/Caspase-1 signaling pathway. DCHD may alleviate SLI by enhancing the intestinal barrier, potentially reducing the translocation of gut-derived LPS to the liver, and subsequently inhibiting the NF-κB/NLRP3/Caspase-1 axis, highlighting its considerable translational potential for SLI therapy.\n\nID: 42290500\nTitle: Probiotic, synbiotic effects on the gut-liver axis: omics-enabled mechanisms and therapeutic windows.\nAbstract: The gut-liver axis is a two-way communication network where gut microbes and their metabolites affect liver function, while the liver regulates the intestinal environment through bile acids, immune factors, and antimicrobial substances. Disruption of this balance contributes to various liver diseases, including nonalcoholic fatty liver disease, alcohol-associated liver disease, cirrhosis, and liver cancer. Probiotics and synbiotics are potential therapies that aim to restore microbial balance, strengthen the intestinal barrier, and regulate inflammation and metabolism. Recent omics technologies, such as metagenomics, metabolomics, transcriptomics, and proteomics, have helped uncover how these interventions influence important pathways involving short-chain fatty acids, bile acids, and microbial metabolites. Studies suggest that probiotics and synbiotics may improve liver health through effects on metabolism, immune regulation, and fibrosis, although results vary depending on the specific microbial strains and patient characteristics. Emerging approaches include next-generation probiotics, targeted synbiotic combinations, and personalized microbiome-based treatments. Combining multi-omics data with digital health tools may help identify patients who are most likely to benefit. Overall, microbiota-targeted therapies show promise as personalized strategies for managing liver diseases, but further research is needed to overcome challenges in translating findings into consistent clinical applications.\n\nID: 42290032\nTitle: Optimization of Deep Eutectic Solvent Extraction Process and Study on the Anti-Alcoholic Fatty Liver Disease Activity and Mechanism of Flavonoids From Lophatherum gracile Brongn.\nAbstract: Deep eutectic solvents (DESs) are a novel type of green extraction medium characterized by strong designability, biodegradability, and high extraction efficiency, making them highly promising for the separation of bioactive components from natural products. Lophatherum gracile Brongn. (L. gracile) is rich in various bioactive components, including flavonoids and polysaccharides. This study established a DES-based extraction system for flavonoids of L. gracile, optimized the process using response surface methodology, and evaluated the antioxidant activity, and hepatoprotective effects of the extracts against alcoholic liver disease (ALD) with focus on gut microbiota modulation. A choline chloride-malic acid DES was identified as the optimal extractant. Under the optimized conditions (extraction time of 60 min, water content of 32%, liquid-to-solid ratio of 61:1 mL/g, molar ratio of 1:1, ultrasonic power of 480 W, and temperature of 60°C), the extraction yield of L. gracile flavonoids reached 16.62 ± 0.27 mg/g. Compared to traditional ethanol extracts, the DES-extracted L. gracile flavonoids exhibited significantly stronger DPPH radical scavenging activity. Moreover, they demonstrated enhanced hepatoprotective effects in an ALD mouse model by ameliorating dyslipidemia, alleviating liver injury, and improving hepatic histopathology. Notably, the DES extracts more effectively reshaped the alcohol-disrupted gut microbiota by increasing beneficial bacteria (e.g., Akkermansia and Lactobacillus) while suppressing pathogenic genera (e.g., Escherichia-Shigella and Bacteroides). These findings provide an efficient and environmentally friendly extraction strategy for L. gracile flavonoids and offer experimental evidence for their potential application in alcoholic liver disease prevention and treatment through gut microbiota modulation.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson’s complementary-but-disjoint (A-B-C) model.

While intestinal FXR inhibition reduces high-fat diet (HFD)-induced hepatic steatosis, its role in MASH progression remains unclear. This study investigates the impact of intestinal FXR-deficiency on MASH development in a diet-induced murine model. Intestinal FXR-deficient (intFXR KO) and control mice were fed a high-fat, sucrose, and cholesterol-enriched diet (HFSC) for 24 weeks. Intestinal immune phenotyping, microarray, 16 S rRNA sequencing, bile acid quantification and liver assessments (histology, biochemistry and single-cell RNA sequencing (scRNA-seq)) were performed. intFXR KO mice were protected against HFSC diet-induced obesity and hepatic steatosis but exhibited altered expression of intestinal barrier-associated genes, with increased cytotoxic CD8+ T-lymphocytes. Microbiota composition and bile acid profiles were altered, including reduced Lachnospiraceae species correlating negatively with liver hyocholic acid levels. Despite a protection against hepatic steatosis, liver inflammation and fibrosis were unchanged in intFXR KO mice. Transcriptomic and Immune cell scRNA-seq analysis revealed alteration in immune-related pathways with an increased neutrophil proportion and higher cDC1:cDC2 and CD4:CD8 T cell ratios. Thus, intestinal FXR-deficiency limits steatosis but promote a distinct hepatic immune-inflammatory response and does not prevent progression to MASH.\n  --- END ACTUAL ABSTRACT FOR 42431962 ---\n\n- ERROR: You cited ID: 42428317 for the quote: \"Herbal polysaccharides and other compounds consistently increased beneficial bacteria and promoted short-chain fatty acids (SCFAs) production, improving intestinal barrier integrity via ZO-1/Occludin upregulation.\"\n  FACT: Strict Misquote Detected!

Herbal medicines offer multi-component therapeutic potential through microbiota modulation, but mechanistic insights remain fragmented. This review synthesizes recent advances in herbal medicine-mediated gut microbiota regulation in metabolic diseases and delineates underlying molecular mechanisms. A comprehensive literature search was conducted across PubMed and Web of Science. Search strategies employed MeSH terms and free-text keywords encompassing herbal medicines, gut microbiota, and metabolic diseases. Two authors performed study selection and data extraction. Evidence synthesis was structured according to intervention type and metabolic disease category. Herbal polysaccharides and other compounds consistently increased beneficial bacteria and promoted short-chain fatty acids (SCFAs) production, improving intestinal barrier integrity via ZO-1/Occludin upregulation and attenuating TLR4/NF-κB-mediated inflammation. Herbal formulations exerted synergistic effects by remodeling microbial community structure, correcting SCFA/bile acid imbalances, and activating IRS1/PI3K/AKT insulin signaling. Notably, Lactobacillus and Akkermansia emerged as recurrent beneficial targets across multiple herbal interventions. However, evidence is predominantly preclinical, and translational validity to humans requires further validation. Herbal medicines ameliorate metabolic diseases through multi-target gut microbiota modulation, involving SCFA production, bile acid metabolism, and inflammatory pathway attenuation. These mechanistic insights support the development of microbiota-targeted herbal therapeutics, though clinical translation necessitates standardized formulations and rigorous human trials.\n  --- END ACTUAL ABSTRACT FOR 42428317 ---\n\n- ERROR: You cited ID: 42395007 for the quote: \"RGE alleviates HFD-induced hyperlipidemia and hepatic steatosis through a coordinated gut-liver axis mechanism, involving microbiota modulation, metabolic reprogramming.\"\n  FACT: Strict Misquote Detected!

However, comprehensive insights into its gut-liver axis mechanisms remain limited. Rats were assigned to a normal control group, an HFD-fed model group, and four groups treated with Korean Red Ginseng extract (RGE) at doses of 125 mg/kg, 250 mg/kg, 500 mg/kg, and 1000 mg/kg. The treatment groups administered RGE by gavage for 60 days while on an HFD. The study evaluated RGE's effects on hyperlipidemia and gut microbiota through serum biochemical analysis, hepatic histopathology, cecal metabolomics, 16S rRNA sequencing, and further investigated hepatic regulatory mechanisms using molecular biology techniques. After 60 days of treatment, RGE significantly reduced serum lipid levels and liver injury markers. Histological analysis using H&E and Oil Red O staining showed that RGE significantly reduced hepatic steatosis in comparison to the model group. LC-MS and 16S rRNA sequencing of cecal contents revealed that RGE remodeled gut microbiota composition, enhancing microbiota-derived metabolite production. Molecular analysis indicated that RGE activated hepatic PPARα, downregulated SREBP-1c, and partially restored basal cholesterol biosynthesis by upregulating HMGCR mRNA. These changes collectively reduced hepatic triglyceride accumulation and promoted cholesterol excretion. RGE alleviates HFD-induced hyperlipidemia and hepatic steatosis through a coordinated gut-liver axis mechanism, involving microbiota modulation, metabolic reprogramming, and regulation of hepatic lipid factors. These findings support RGE as a potential therapeutic option for hyperlipidemia and related metabolic disorders, using an \"excretion-centric\" strategy.\n  --- END ACTUAL ABSTRACT FOR 42395007 ---\n\n- ERROR: You cited ID: 42377574 for the quote: \"Butyrate supplementation during gestation reduces placental inflammation and ameliorated offspring hepatic steatosis.\"\n  FACT: Strict Misquote Detected!

Placental inflammation acts as a critical mediator with poorly addressed etiology. Recently HFD-induced gut dysbiosis is demonstrated to be a key driver of systemic inflammation. Whether inflammatory signals triggered by HFD-induced gut dysbiosis are transmitted to the placenta via the maternal-fetal axis warrant further investigation. This study aims to elucidate the mechanistic connection between maternal gut dysbiosis and placental inflammation, thereby offering insights into microbiota-mediated developmental origins of metabolic diseases in offspring. Female C57BL/6 mice were exposed to high fat diet (HFD) for 5 weeks prior to mating with male mice. Gut microbiota was profiled by using 16 S rRNA sequencing and fecal short-chain fatty acids (SCFAs) were quantified by GC-MS from HFD pregnant mice at gestational day 18.5 (G18.5). Mice were sacrificed at G18.5, and placenta histopathological analysis as well as inflammatory markers and lipopolysaccharide (LPS) level were analyzed. Anti-inflammatory effects of butyrate were evaluated in vitro by using HTR-8/Svneo cells and in vivo through gestational supplementation (0.3 mg/g body weight) in HFD-fed dams. Maternal HFD exposure induced significant placental inflammation as well as hepatic steatosis in the offspring. HFD-fed dams exhibited distinct gut dysbiosis with reduced fecal and serum SCFAs, which was accompanied by elevated placental LPS levels and exacerbated inflammatory responses. Butyrate treatment suppressed the expression of inflammatory cytokines in vitro through down-regulating the phosphorylation of NF-κB, ERK1/2 signaling pathways via G-protein-coupled receptor 41 (GPR41). Furthermore, gestational butyrate intervention effectively alleviated placental inflammation and mitigated fetal hepatic lipid deposition in HFD-exposed offspring. Placental inflammation caused by maternal HFD is closely associated with gut microbiota dysbiosis. Butyrate supplementation during gestation reduces placental inflammation and ameliorated offspring hepatic steatosis, highlighting the therapeutic potential of butyrate for mitigating the adverse metabolic programming effects upon maternal HFD exposure.\n  --- END ACTUAL ABSTRACT FOR 42377574 ---\n\n- ERROR: You cited ID: 42354872 for the quote: \"OA mitigates metabolic stress in Nile tilapia by reconfiguring the gut-liver axis, integrating microbial restoration with precise regulation of hepatic nutrient-sensing and inflammatory pathways.\"\n  FACT: Strict Misquote Detected!

Fish were allocated to four groups: normal diet (ND), HFD, and OA-supplemented HFD (50 and 250 mg/kg). After 42 days, physiological, biochemical, and histological assessments demonstrated that OA markedly reduced hepatic lipid accumulation, mitochondrial injury, and intestinal shortening. Transcriptomic analysis revealed that OA alleviated lipid dysregulation by inhibiting de novo lipogenesis and promoting lipid trafficking and β-oxidation, effectively reversing HFD-induced changes in the PPAR, MAPK, mTOR, and autophagy-lysosome signaling pathways. 16S rRNA sequencing indicated that OA increased microbial alpha diversity, suppressing HFD-associated taxa (e.g., Nordella) while enriching beneficial genera such as Clavibacter, Bosea, and Bdellovibrio. Importantly, OA treatment restored HFD-induced depletion of intestinal butyric acid and suppressed hepatic pro-inflammatory cytokines (tnf-α, il-1β), while upregulating growth-related factors (igf1). Correlation analysis confirmed strong associations between microbial alterations (Nordella and Phreatobacter) and hepatic lipid metabolism and inflammatory gene expression. Overall, OA mitigates metabolic stress in Nile tilapia by reconfiguring the gut-liver axis, integrating microbial restoration with precise regulation of hepatic nutrient-sensing and inflammatory pathways, providing a potential therapeutic strategy for lipid metabolism disorders in aquaculture.\n  --- END ACTUAL ABSTRACT FOR 42354872 ---\n\n- ERROR: You cited ID: 42353191 for the quote: \"Intervention with Akk11 alleviated liver injury, reduced lipid accumulation and oxidative stress, and restored cytokine balance.

This study aimed to clarify the pathogenic effects of E. faecalis in acute alcohol-associated liver disease (ALD) and to assess the protective potential of Akkermansia muciniphila (Akk11) against this pathogen. Using a mouse model of acute ethanol gavage, animals received E. faecalis and/or Akk11 under prophylactic or therapeutic regimens. Assessments included liver injury markers, histopathology, lipid profiles, inflammatory cytokines, gut barrier integrity, and gut microbiota composition. E. faecalis exacerbated ethanol-induced hepatic steatosis and injury, showing a paradoxical effect: it increased histological damage while lowering circulating LPS and transaminases. This was linked to upregulated hepatic autophagy (increased Atg7) and reduced cholesterol, yet it promoted neutral lipid accumulation. Importantly, E. faecalis aggravated gut dysbiosis by markedly enriching the pro-inflammatory pathobiont Helicobacter typhlonius and impairing colonic barrier function. Intervention with Akk11 alleviated liver injury, reduced lipid accumulation and oxidative stress, and restored cytokine balance. Akk11 also strengthened gut barrier integrity, lowered serum endotoxin, and beneficially reshaped the microbiota. Prophylactic administration was particularly effective, normalizing the Firmicutes/Bacteroidota ratio, suppressing H. typhlonius, and enriching beneficial Bacteroides sartorii. This study confirms the pathogenic role of E. faecalis in acute ALD and establishes A. muciniphila (Akk11) as a promising microbiota-targeted therapy, which protects against liver injury by reinforcing the gut barrier, selectively modulating microbiota, and reducing inflammation, with prophylactic administration showing superior efficacy.\n  --- END ACTUAL ABSTRACT FOR 42353191 ---\n\n- ERROR: You cited ID: 42352035 for the quote: \"Lacticaseibacillus rhamnosus GG enhances tight junctions (ZO-1)... and pasteurized Akkermansia muciniphila remodels bile acids.\"\n  FACT: Ellipses (...) are strictly forbidden.

However, sex and reproductive age may influence their effect. We investigated the effect of liraglutide administration (0.2 mg/kg/day subcutaneously for 8 weeks) on metabolic disorders in relation to sex and reproductive age, using male, female and ovariectomized female hereditary hypertriglyceridemic (HHTg) rats as a prediabetic model. Liraglutide improved glucose tolerance in all HHTg rats. Female and ovariectomized (OVX) female rats showed a stronger effect of lipid metabolism and visceral adiposity than males. Moreover, no changes in hepatic triacylglycerol (TAG) accumulation were observed in males. Liraglutide partially reversed ovariectomy effects, such as increased body weight, visceral obesity and impaired glucose tolerance. Compared with males, female and OVX female rats showed more significant changes in hepatic gene expression involved in lipogenesis (Scd-1, Srebp1, Pparγ), fatty acid and lipid metabolism (Pparα, Hmgcr, Srebp2) and fibrosis (Tgfβ), which may improve hepatic lipid metabolism. Females of fertile age showed greater improvements in insulin sensitivity, reductions in ectopic lipid accumulation, and improvements in lipid metabolism. Depending on sex and reproductive status, liraglutide can mitigate fatty liver before diabetes onset.\n  --- END ACTUAL ABSTRACT FOR 42352035 ---\n\n- ERROR: You cited ID: 42339503 for the quote: \"Non-surgical periodontal therapy demonstrated therapeutic potential by simultaneously improving periodontal health and attenuating non-alcoholic fatty liver disease progression.\"\n  FACT: Strict Misquote Detected!

This review systematically elucidates molecular crosstalk through the \"oral-gut-liver axis\" and \"oral-liver axis\". A comprehensive literature review was conducted using PubMed, Scopus and Web of Science, employing keywords related to periodontal disease and non-alcoholic fatty liver disease. Analysis of 16 original studies revealed that periodontitis and its associated pathogens promote the progression of non-alcoholic fatty liver disease through multiple pathways: (1) activation of hepatic inflammatory responses (elevated IL-6, IL-17, and TNF-α levels), (2) exacerbation of metabolic dysregulation (increased HOMA-IR, ALT, and AST), and (3) disruption of the oral-gut-liver axis. Notably, non-surgical periodontal therapy demonstrated therapeutic potential by simultaneously improving periodontal health and attenuating non-alcoholic fatty liver disease progression through reduction of hepatic pro-inflammatory cytokines and fibrogenic mediators. Periodontitis may exacerbate systemic inflammation via the oral-liver and oral-gut-liver axes, inducing insulin resistance and promoting non-alcoholic fatty liver disease. Non-surgical periodontal therapy can improve non-alcoholic fatty liver disease, but methodological heterogeneity in current studies necessitates further prospective research to clarify their relationship.\n  --- END ACTUAL ABSTRACT FOR 42339503 ---\n\n- ERROR: You cited ID: 42327337 for the quote: \"Semaglutide... improved maternal metabolism and ameliorated metabolic dysfunction in offspring caused by maternal high-fat diet.\"\n  FACT: Ellipses (...) are strictly forbidden.

Here, we evaluated the safety and metabolic effects of semaglutide, a GLP-1 receptor agonist (GLP-1 RA), administered from preconception through lactation in dams fed a high-fat diet (HFD) or standard diet, and assessed metabolic outcomes in dams and their offspring. Offspring were weaned to a standard diet. We found that semaglutide improved body composition and glucose metabolism in HFD-fed dams during pregnancy. These maternal changes persisted 10 weeks after weaning despite discontinuation of semaglutide treatment. HFD exposure impaired glucose homeostasis and promoted hepatic steatosis in offspring at 18 weeks. These effects were ameliorated by maternal semaglutide treatment. Importantly, metabolic improvements in dams and offspring occurred without adverse effects on conception rate or fetal viability. These findings suggest that GLP-1 RA during the perinatal period can improve maternal and offspring metabolic health in a mouse model of obesity and support further investigation of GLP-1-based therapies to mitigate maternal metabolic dysfunction and improve metabolic risk in children. Rates of obesity, type 2 diabetes, and fatty liver disease are rising in children, in part due to maternal obesity and insulin resistance that program offspring metabolic risk during the perinatal period.We asked whether the GLP-1 receptor agonist (GLP-1 RA), semaglutide, administered during critical developmental windows could prevent adverse outcomes in offspring using a diet-induced mouse model of maternal obesity.Semaglutide, given to dams from preconception through lactation, improved maternal metabolism and ameliorated metabolic dysfunction in offspring caused by maternal high-fat diet.These findings highlight a potential role for perinatal GLP-1 receptor agonism to improve maternal metabolic health and reduce metabolic risk in offspring.\n  --- END ACTUAL ABSTRACT FOR 42327337 ---\n\n- ERROR: You cited ID: 42298689 for the quote: \"DCHD may alleviate SLI by enhancing the intestinal barrier, potentially reducing the translocation of gut-derived LPS to the liver.\"\n  FACT: Strict Misquote Detected!

Dachaihu decoction (DCHD), a classic traditional Chinese medicine formula recorded in the Treatise on Cold Damage, is widely used to treat gastrointestinal and hepatic inflammatory conditions. The primary objective of our research was to elucidate the protective effects of DCHD against SLI and the underlying molecular mechanisms. In a murine model of sepsis induced by cecal ligation and puncture (CLP), we evaluated the therapeutic effects of DCHD on SLI by assessing serum liver enzymes, histopathology, oxidative stress, hepatocyte apoptosis, and inflammatory cytokines. Intestinal barrier integrity was examined via transmission electron microscopy, serum biomarkers (D-lactate, DAO, LPS), and tight junction proteins (ZO-1, Occludin, E-cadherin). Gut microbiota composition was analyzed using 16S rRNA sequencing. Chemical profiling of DCHD was performed via UPLC-Q-TOF-MS. Integrated network pharmacology, bioinformatics, and transcriptomic analyses identified the NF-κB/NLRP3/Caspase-1 axis as a potential mechanism, which was validated in vivo and in LPS-stimulated immortalized mouse Kupffer cells (ImKCs). Functional involvement of TLR4 and NLRP3 was further confirmed by genetic silencing of TLR4 with siRNA and pharmacological inhibition using TAK-242 (TLR4 inhibitor) and MCC950 (NLRP3 inhibitor). DCHD treatment attenuated liver injury in CLP-induced septic mice, as evidenced by improved liver function, attenuated histopathology, reduced oxidative stress, suppressed inflammation, and decreased hepatocyte apoptosis. These hepatoprotective effects were associated with reduced intestinal permeability and enhanced barrier integrity, alongside gut microbiota remodeling characterized by enrichment of beneficial bacteria and reduced abundance of gram-negative genera (e.g., Klebsiella, Enterobacter, Proteus), leading to decreased LPS production and translocation to the liver. Integrated network pharmacology and transcriptomics revealed the NF-κB/NLRP3/Caspase-1 axis as a central mechanism, with DCHD downregulating p-p65, p-IκBα, NLRP3, ASC, and Cleaved Caspase-1 in vivo and in LPS-stimulated ImKCs. Functional validation using TLR4 siRNA and the inhibitors TAK-242 and MCC950 confirmed that DCHD might attenuate liver inflammatory injury primarily through the NF-κB/NLRP3/Caspase-1 signaling pathway. DCHD may alleviate SLI by enhancing the intestinal barrier, potentially reducing the translocation of gut-derived LPS to the liver, and subsequently inhibiting the NF-κB/NLRP3/Caspase-1 axis, highlighting its considerable translational potential for SLI therapy.\n  --- END ACTUAL ABSTRACT FOR 42298689 ---\n\n- ERROR: You cited ID: 42290032 for the quote: \"DES-extracted L. gracile flavonoids exhibited significantly stronger DPPH radical scavenging activity... improved hepatic histopathology... effectively reshaped the alcohol-disrupted gut microbiota.\"\n  FACT: Ellipses (...) are strictly forbidden.

Lophatherum gracile Brongn. (L. gracile) is rich in various bioactive components, including flavonoids and polysaccharides. This study established a DES-based extraction system for flavonoids of L. gracile, optimized the process using response surface methodology, and evaluated the antioxidant activity, and hepatoprotective effects of the extracts against alcoholic liver disease (ALD) with focus on gut microbiota modulation. A choline chloride-malic acid DES was identified as the optimal extractant. Under the optimized conditions (extraction time of 60 min, water content of 32%, liquid-to-solid ratio of 61:1 mL/g, molar ratio of 1:1, ultrasonic power of 480 W, and temperature of 60°C), the extraction yield of L. gracile flavonoids reached 16.62 ± 0.27 mg/g. Compared to traditional ethanol extracts, the DES-extracted L. gracile flavonoids exhibited significantly stronger DPPH radical scavenging activity. Moreover, they demonstrated enhanced hepatoprotective effects in an ALD mouse model by ameliorating dyslipidemia, alleviating liver injury, and improving hepatic histopathology. Notably, the DES extracts more effectively reshaped the alcohol-disrupted gut microbiota by increasing beneficial bacteria (e.g., Akkermansia and Lactobacillus) while suppressing pathogenic genera (e.g., Escherichia-Shigella and Bacteroides). These findings provide an efficient and environmentally friendly extraction strategy for L. gracile flavonoids and offer experimental evidence for their potential application in alcoholic liver disease prevention and treatment through gut microbiota modulation.\n  --- END ACTUAL ABSTRACT FOR 42290032 ---\n\n- ERROR: You cited ID: 42277386 for the quote: \"probiotics and prebiotics... converge on the TLR4/NF-κB axis as the central mechanistic driver of cytokine dysregulation in MASLD.\"\n  FACT: Ellipses (...) are strictly forbidden.

Emerging evidence underscores the gut-liver axis as a pivotal pathway in MASLD pathogenesis through which dysbiosis drives cytokine-mediated inflammation, fibrosis, and disease progression. This review synthesizes preclinical and clinical findings on how probiotics and prebiotics modulate key inflammatory cytokines-including TNF-α, IL-6, IL-1β, IL-10, IL-17, and TGF-β-to ameliorate MASLD. The literature demonstrates that these interventions converge on the TLR4/NF-κB axis as the central mechanistic driver of cytokine dysregulation in MASLD. By restoring gut barrier integrity and reducing endotoxin (LPS) translocation, probiotics and prebiotics suppress TLR4/NF-κB activation, which secondarily inhibits the NLRP3 inflammasome (reducing IL-1β/IL-18), downregulates pro-inflammatory cytokines (TNF-α, IL-6, IL-17), and enhances anti-inflammatory signals (IL-10) through crosstalk with PPAR-α, AMPK, and Nrf2 pathways. In animal models, probiotic strains such as Bifidobacterium, Lactobacillus, and Akkermansia muciniphila consistently downregulate pro-inflammatory cytokines and enhance anti-inflammatory signals. The same is true for prebiotics, including inulin, oat β-glucan, and synbiotic formulations. However, clinical trial outcomes remain heterogeneous, influenced by strain specificity, intervention duration, and patient heterogeneity. Collectively, this review highlights the therapeutic potential of microbiota-targeted interventions to rebalance cytokine networks and proposes future directions for personalized, mechanism-driven approaches to the management of MASLD.\n  --- END ACTUAL ABSTRACT FOR 42277386 ---\n\n- ERROR: You cited ID: 42217069 for the quote: \"treatment alleviated metabolic parameters, liver steatosis, and injury.

In this study, we propose a novel dietary therapy for NAFLD utilizing a conjugate of chitooligosaccharide (COS) and epigallocatechin gallate (EGCG), as the underlying mechanisms of NAFLD remain unclear. NAFLD was induced in male Wistar rats by administering a high-fat diet (HFD) for 16 weeks, followed by administration of COS-EGCG conjugate (150, 300, and 600 mg/kg) for an additional four weeks. The treatment alleviated metabolic parameters, liver steatosis, and injury. It also reduced hepatic lipid accumulation by downregulating the expression of CD36, fatty acid synthase (FASN), and sterol regulatory element-binding protein 1c (SREBP-1c), while upregulating peroxisome proliferator-activated receptor alpha (PPARα), carnitine palmitoyltransferase 1 A (CPT1A), and microsomal triglyceride transfer protein (MTTP). Regarding the gut-liver axis, the conjugate modulated gut microbiota, reduced serum lipopolysaccharide (LPS) levels, and restored the expression of intestinal tight junction proteins (zonula occludens-1; ZO-1 and occludin). It also prevented liver inflammation induced by gut-derived LPS by suppressing the Toll-like receptor 4 (TLR4)/nuclear factor kappa B (NF-κB) signaling pathway. The results suggest that the COS-EGCG conjugate exerts therapeutic effects against NAFLD by regulating hepatic lipid metabolism, modulating the gut microbiota, and attenuating gut-derived LPS-induced liver inflammation.\n  --- END ACTUAL ABSTRACT FOR 42217069 ---\n\n\n✅ PASSED (DO NOT CHANGE THESE):\n- \"Sinensetin administration ameliorated hepatic steatosis, inflammation, and restored intestinal integrity in HFD-fed mice.\" (Source: 42421922)\n- \"hepatic alkaline phosphatase released from diseased liver suppresses intestinal stem cell differentiation into GLP-1-secreting L-cells.\" (Source: 42413475)\n- \"LBSPs restored intestinal barrier integrity by up-regulating tight junction proteins Claudin-1, Occludin, and Zonula Occludens-1 (ZO-1).\" (Source: 42385432)\n- \"SCPs were also associated with improved intestinal morphology, increased mucin-associated staining, decreased serum diamine oxidase levels and reduced hepatic lipopolysaccharide accumulation.\" (Source: 42356415)\n- \"DOP improves NAFLD through dual mechanisms of regulating the gut-liver axis homeostasis and directly activating the liver SIRT6/PGC-1α signaling pathway.\" (Source: 42311944)\n- \"BBR markedly ameliorated MASH-related phenotypes by suppressing the NF-κB/HDAC1/SREBP-1c axis.\" (Source: 42276391)\n- \"MASH results from the complex coupling of metabolic imbalance and immune-driven inflammation, making single-target therapy insufficient.\" (Source: 42245952)\n\n\nINSTRUCTION: Study the actual abstracts provided.

The bidirectional nature of this axis implies that treatments focusing on lipid metabolism and inflammatory pathways often result in secondary restoration of gut microbiota composition and intestinal barrier function.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe pathophysiology of metabolic dysfunction-associated fatty liver disease (MASLD) involves complex crosstalk between the liver and the gut, mediated by metabolites, inflammatory cytokines, and hormonal signaling. Evidence demonstrates that the liver can influence gut health; for instance, \"hepatic alkaline phosphatase released from diseased liver suppresses intestinal stem cell differentiation into GLP-1-secreting L-cells.\" Conversely, many therapeutic interventions for fatty liver disease focus on rebalancing this axis. Bioactive compounds like LBSPs have been shown to be effective, as \"LBSPs restored intestinal barrier integrity by up-regulating tight junction proteins Claudin-1, Occludin, and Zonula Occludens-1 (ZO-1).\" Furthermore, systemic metabolic improvement achieved through pharmacological means or natural compounds often leads to gut-level benefits. For example, \"Sinensetin administration ameliorated hepatic steatosis, inflammation, and restored intestinal integrity in HFD-fed mice.\" Therapeutic approaches must address the \"complex coupling of metabolic imbalance and immune-driven inflammation, making single-target therapy insufficient.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Hepatic alkaline phosphatase acts as a regulatory node that can inhibit the production of GLP-1 secreting cells in the intestine.\n*   Certain medicinal extracts, like those from *Lophatherum gracile*, can reshape alcohol-disturbed gut microbiota by increasing *Akkermansia* and *Lactobacillus*.\n*   Maternal butyrate administration during gestation can prevent the programming of fetal fatty liver disease, illustrating the developmental window of the gut-liver axis.\n*   Exercise serves as a potent non-pharmacological modulator that attenuates hepatic lipid peroxidation even without significant weight loss.\n*   Specific biomarkers, such as EGFR, HMOX1, and LGMN, have been identified as having transcriptomic correlation with metabolic cell death in NAFLD.\n*   The use of deep eutectic solvents for extracting flavonoids provides a greener, highly efficient methodology for preparing therapeutic agents for ALD.\n*   Intestinal FXR deficiency uncouples steatosis protection from liver inflammation, suggesting that blocking FXR in the gut may limit steatosis while paradoxically promoting distinct inflammatory responses.\n*   Marine-derived peptides, such as those from *Solenocera crassicornis*, are associated with improved mucin-associated staining and barrier integrity during diet normalization.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

with dysbiosis closely associated with the onset and progression of chronic liver diseases. This review systematically examines the central role of the \"oral-gut-liver axis\" in hepatic pathophysiology. Epidemiological evidence has identified periodontitis and specific oral pathogens, such as Fusobacterium nucleatum (F. nucleatum), as independent risk factors for the progression of non-alcoholic fatty liver disease (NAFLD), development of cirrhosis, and incidence of hepatocellular carcinoma (HCC). The underlying mechanisms primarily involve four interrelated pathways: (1) direct bacterial translocation, where pathogens such as F. nucleatum colonize the liver via bacteremia and activate oncogenic pathways; (2) systemic dissemination of bacterial metabolites, such as lipopolysaccharides (LPS), driving hepatic inflammation, oxidative stress, and fibrosis via Toll-like receptor 4 (TLR4) signaling and reactive oxygen species (ROS)-mediated pathways; (3) systemic immune inflammation, wherein periodontitis acts as a chronic inflammatory focus that continuously releases pro-inflammatory mediators into the circulation; and (4) indirect effects mediated by gut microbiota dysbiosis, whereby oral bacteria compromise the intestinal barrier, facilitating the influx of gut-derived toxins into the liver. These findings underscore the significant impact of oral health on hepatic status. In the short term, oral microbial profiles represent promising noninvasive diagnostic and prognostic biomarkers. Preliminary clinical trials indicate that periodontal therapy can improve metabolic parameters in patients with NAFLD. In the long term, promoting interdisciplinary collaboration between hepatology and oral medicine and strategically integrating oral health interventions into the comprehensive management framework for liver diseases hold significant public health potential for mitigating the global burden of hepatic disorders.","42114284":"ID: 42114284\nTitle: Functional effects of rosmarinic acid on gut health and epigenetic regulation in antibiotic-free poultry diets.\nAbstract: Rosmarinic acid (RA), a bioactive polyphenol found in Salvia officinalis and other Lamiaceae herbs, has attracted attention for its functional feed application in animal nutrition. RA supplementation positively influences growth efficiency, liver antioxidant status, and serum biochemical indices in broilers. Its antimicrobial and immunomodulatory effects promote health and productivity. Studies suggest benefits for gut health and meat quality; however, epigenetic regulation of RA in poultry is considered a minor future perspective, being mostly based on mammalian studies. Hypothesized impacts of RA on chronic disease prevention and as a microbiome-engineering agent require further investigation. This review explores the regulatory effects of RA on DNA methylation, non-coding RNAs (ncRNAs), and histone modifications, which influence gut microbiome structure, nutrient absorption, and immune function in poultry. It emphasizes RA's potential as a functional food for gastrointestinal health, metabolic regulation, and chronic disease prevention, alongside its use in antibiotic-free poultry feed for microbiome engineering. The review also discusses RA's effects on lipid metabolism and oxidative stress, highlighting its role in maintaining intestinal barrier health. Nevertheless, certain limitations must be acknowledged, as successful nutritional interventions depend on understanding individual variability, including genetics, metabolism, age, and health status. Tailored methodologies, such as micronutrition and genomic nutrition, can improve diet quality, promote nutrient absorption, and enhance overall animal health. A tailored feeding regimen focuses on selecting nutrients with proven benefits for key health outcomes, such as omega-3 fatty acids, which scientific evidence shows promote brain and heart health while reducing inflammation.","42126781":"ID: 42126781\nTitle: Bisphosphoglycerate mutase is involved in glucose metabolism and progression of nonalcoholic fatty liver disease based on liver organoids.\nAbstract: This study seeks to investigate the underlying mechanism of glycolytic key gene bisphosphoglycerate mutase (BPGM) in nonalcoholic fatty liver disease (NAFLD). qRT-PCR and immunohistochemistry were utilized to detect BPGM levels in clinical NAFLD samples. HepG2 cells and liver organoids were treated with free fatty acid. (FFA). The role of BPGM in NAFLD was explored at cellular, organoid, and animal levels. Metabolomics was performed to analyze differential metabolites and metabolic pathways. Furthermore, we examined the regulatory mechanisms of BPGM by HIF-1α in NAFLD. Results indicated that high expression of BPGM in NAFLD samples was correlated with NAFLD progression. Moreover, Severe group had higher BPGM expression than Mild group. FFA treatment induced time-dependent steatosis and BPGM upregulation in HepG2 cells and liver organoids, whereas BPGM knockdown attenuated lipid accumulation, cellular injury, and oxidative stress. At the animal level, knockdown of BPGM reversed high-fat diet (HFD) induced lipid accumulation and liver tissue injury. Metabolomics studies showed significant changes of metabolic pathways including glycolysis/gluconeogenesis and pyruvate metabolism. Verification experiment showed FFA increased pyruvic acid levels, and knockdown of BPGM decreased pyruvic acid levels. Pyruvic acid further reversed the changes in NAFLD progression caused by BPGM knockdown at the cellular and organoid levels. Finally, HIF-1α regulated the expression of BPGM in NAFLD. Together, our findings suggest that BPGM contributes to abnormal glucose metabolism and promotes hepatic steatosis, thereby driving NAFLD progression.","42154845":"ID: 42154845\nTitle: AEROBIC EXERCISE ATTENUATES HEPATIC LIPID PEROXIDATION IN AN EXPERIMENTAL MODEL OF OBESITY-ASSOCIATED NAFLD.\nAbstract: The global rise in obesity has been accompanied by an increasing prevalence of nonalcoholic fatty liver disease (NAFLD), for which effective non-pharmacological therapeutic strategies remain limited. This study investigated the effects of aerobic exercise on hepatic oxidative stress in an experimental model of obesity-associated NAFLD. Newly weaned Wistar rats were fed a highly palatable, obesity-inducing diet. After obesity was established, the animals were randomly assigned to either a trained group (n=12) or a sedentary group (n=12). The trained group underwent moderate-intensity treadmill running for eight weeks. Hepatic lipid peroxidation was assessed using the TBARS (thiobarbituric acid reactive substances) assay. Aerobic training significantly reduced hepatic TBARS levels (P<0.0005), in an average of 1.8 nmol MDA/mg protein compared to the sedentary group. These benefits were significant regardless of weight gain maintenance. The findings suggest that regular physical exercise attenuates hepatic lipid peroxidation in an experimental model of obesity-associated NAFLD. The results support that physical exercise is an effective non-pharmacological strategy for modulating oxidative stress and preventing disease progression. O aumento global da obesidade tem sido acompanhado de prevalência crescente da doença hepática gordurosa não alcoólica (DHGNA), para a qual ainda são limitadas estratégias terapêuticas não farmacológicas eficazes. Este estudo investigou os efeitos do exercício aeróbico sobre o estresse oxidativo hepático em um modelo experimental de obesidade associada à DHGNA. Ratos Wistar recém-desmamados foram alimentados com dieta altamente palatável e indutora de obesidade. Após o estabelecimento da obesidade, os animais foram divididos aleatoriamente em grupos treinados (n=12) e sedentários (n=12). O grupo treinado foi submetido à corrida em esteira de intensidade moderada por oito semanas. A peroxidação lipídica hepática foi avaliada por meio do método TBARS (substâncias reativas ao ácido tiobarbitúrico). O treinamento aeróbico reduziu significativamente os níveis hepáticos de TBARS (P<0,0005), em uma média de 1,8 nmol MDA/mg de proteína em comparação ao grupo sedentário. Esses benefícios foram evidentes, apesar da manutenção do ganho de peso. Os achados sugerem que o exercício físico regular atenua a peroxidação lipídica hepática em modelo experimental de DHGNA associada à obesidade. Os resultados indicam que o exercício físico é uma estratégia não farmacológica eficiente na modulação do estresse oxidativo e na prevenção da progressão da doença.","42164255":"ID: 42164255\nTitle: Chlorogenic acid modulates gut microbiota and metabolites to alleviate intrahepatic cholestasis of pregnancy: Insights from 16S rRNA sequencing and metabolomics.\nAbstract: Intrahepatic cholestasis of pregnancy (ICP) is a liver disorder marked by impaired bile flow, elevated serum bile acids, and pruritus, posing significant risks to maternal and fetal health. Current treatments, including ursodeoxycholic acid, have shown limited efficacy, underscoring the need for more effective therapies. Chlorogenic acid (CGA), a polyphenolic compound with antioxidant, anti-inflammatory, and hepatoprotective properties, has shown promise in managing liver diseases, but its role in ICP remains poorly understood. This study investigated the therapeutic effects of CGA in a rat model of ICP induced by 17α-ethinylestradiol. CGA treatment significantly reduced liver enzyme levels, total bile acids, and bilirubin, while improving histopathological liver damage. CGA also modulated key proteins involved in bile acid synthesis and transport, including FXR, CYP7A1, NTCP, and BSEP. Additionally, CGA treatment improved intestinal barrier function by upregulating tight junction proteins, including ZO-1. Metabolomics and 16S rRNA gene sequencing revealed that CGA treatment restored gut microbiota balance in ICP rats. CGA demonstrated a dose-dependent response, with higher doses providing more pronounced therapeutic effects. These findings suggest that CGA alleviates ICP by regulating bile acid metabolism, improving liver function, and modulating the gut microbiome, highlighting its potential as an effective therapeutic option for managing ICP.","42171826":"ID: 42171826\nTitle: Emerging roles of combined curcumin and berberine in disease modulation: a comprehensive review of mechanisms and therapeutic relevance.\nAbstract: Curcumin, a polyphenolic compound derived from Curcuma longa, and berberine, an isoquinoline alkaloid extracted from plants such as Coptis chinensis, exhibit multifaceted pharmacological properties, including potent antioxidant, anti-inflammatory, antimicrobial, and anticancer effects. This narrative review evaluates their therapeutic potential across a diverse range of conditions, including nonalcoholic fatty liver disease (NAFLD), various malignancies, wound and plant infections, Alzheimer's disease, cardiovascular disorders, irritable bowel syndrome, cyclophosphamide-induced toxicity, interstitial cystitis, and systemic lupus erythematosus. Mechanistically, curcumin and berberine modulate gut microbiota, suppress lipogenic and inflammatory pathways (e.g., SREBP-1c and NF-κB), and activate PI3K/Akt and PPARγ signaling, thereby reducing hepatic steatosis and inflammation. Furthermore, they induce apoptosis, inhibit the PI3K/Akt/mTOR pathway, and modulate the tumor microenvironment, with their enhanced combined effects being significantly amplified by nanodelivery systems, such as liposomes. Their antimicrobial efficacy targets methicillin-resistant Staphylococcus aureus (MRSA) and plant pathogens by disrupting biofilms and generating reactive oxygen species via nanofibers and self-assembled submicron particles. Moreover, they reduce amyloid-beta aggregation, promote autophagy, and mitigate neuroinflammation. Additionally, their immunomodulatory properties effectively suppress autoimmune responses. Ultimately, this review synthesizes the current evidence regarding the therapeutic versatility of curcumin and berberine across multiple pathologies.","42182019":"ID: 42182019\nTitle: Restoring circadian disrupted gut microbial metabolite rhythms with phytochemicals: a new avenue against metabolic disease.\nAbstract: The global epidemic of metabolic diseases-encompassing obesity, type 2 diabetes mellitus (T2DM), non-alcoholic fatty liver disease (NAFLD), and cardiovascular disease-represents a defining public health challenge of our era. The traditional model of simple caloric excess vs. expenditure has proven insufficient, giving way to a paradigm that acknowledges complex interactions between genetics, environment, and lifestyle, mediated by intricate physiological systems. Among these, the host circadian timing system and the gut microbiome have ascended as pivotal, deeply intertwined regulators of metabolic homeostasis. The gut microbiome, far from a static collection of microbes, constitutes a dynamic and metabolically active community whose composition and, critically, its functional output exhibit profound and predictable diurnal oscillations. The host's circadian clocks regulate microbial rhythms primarily by controlling the daily cycle of feeding and fasting. Modern life induces circadian disruption (CD) through ubiquitous exposure to artificial light at night, shift work, social jet lag, and erratic eating patterns. It perturbs the rhythmic dynamics of the gut ecosystem, leading to a fundamental dysregulation in the temporal production of key microbial metabolites. These metabolites, including short-chain fatty acids, secondary bile acids (BAs), indoles and other tryptophan derivatives, function as indispensable chemical messengers that coordinate peripheral metabolism, immune responses, and energy homeostasis in a precise, time-of-day-dependent manner. Their desynchronization-manifesting as mistimed, deficient, or incessant signaling-directly instigates the core pathologies of metabolic disease: insulin resistance, adipocyte dysfunction, hepatic lipid accumulation, and chronic low-grade inflammation. This review synthesizes current evidence to delineate the multilevel mechanisms through which CD drives the dysregulation of gut microbiome metabolite rhythms and establishes the causal pathways linking this dysrhythmia to metabolic pathogenesis. Furthermore, we undertake a critical evaluation of the promising therapeutic potential of dietary phytochemicals-a diverse class encompassing polyphenols, glucosinolates, and prebiotic fibers-to act as chrono-therapeutic agents. Through their multifaceted capacity to remodel microbial ecology, calibrate microbial enzymatic output, and reinforce host circadian-metabolic coupling, phytochemicals present a novel, physiologically aligned, and sustainable dietary strategy for the prevention and management of metabolic disorders. We conclude by outlining key translational challenges and propose future research directions essential for harnessing the potential of the \"clock-microbiome-metabolite\" axis within the framework of precision nutrition and medicine.","42182451":"ID: 42182451\nTitle: Targeting Microbial Bile Salt Hydrolase Reprograms Bile Acid Metabolism and Ameliorates Metabolic Dysfunction-Associated Steatohepatitis in Mice.\nAbstract: Microbial bile salt hydrolase (BSH) plays a central role in shaping bile acid composition and gut-liver metabolic signaling, yet its therapeutic potential in metabolic dysfunction-associated steatohepatitis (MASH) remains incompletely defined. Here, we evaluated the efficacy of the non-absorbable BSH inhibitor GR-7 in a diet induced mouse model of steatohepatitis using early and late intervention strategies with different dosing regimens. GR-7 reduced food intake and exerted stage- and dose-dependent therapeutic effects, with early intervention robustly suppressing hepatic fibrosis even at low dose, whereas late-stage administration of high-dose GR-7 markedly reduced hepatic steatosis and inflammation, as evidenced by decreased liver weight, hepatic triglyceride and cholesterol levels, and plasma ALT. Although late intervention did not result in statistically significant histological reversal of fibrosis, a trend toward improvement was observed, together with suppression of fibrogenic gene expression, suggesting that prolonged treatment may further enhance antifibrotic efficacy. Mechanistically, GR-7 effectively inhibited microbial BSH activity in vivo, leading to reduced cecal unconjugated primary and secondary bile acids-including deoxycholic acid and lithocholic acid, which was associated with improved gut barrier integrity and reduced hepatic inflammation. In parallel, BSH inhibition reprogrammed hepatic bile acid metabolism toward activation of the alternative CYP27A1-mediated synthesis pathway, accompanied by reduced food intake, thereby contributing to improved hepatic lipid accumulation. Furthermore, late-stage high-dose treatment selectively remodeled the hepatic immune landscape rather than fully restoring homeostasis, highlighting immune recalibration as a key component of therapeutic response. Together, these findings identify microbial BSH inhibition as a promising microbiome-targeted therapeutic strategy for MASH.","42183058":"ID: 42183058\nTitle: Gut-engineered Bacillus subtilis-mediated BAMBI delivery for the treatment of thioacetamide-induced liver fibrosis through mechanotransduction inhibition.\nAbstract: Liver fibrosis, driven by chronic injury and excessive extracellular matrix (ECM) deposition, lacks effective clinical therapies. This study pioneers a strategy employing genetically engineered Bacillus subtilis (strain Bs-BAMBI-8) to constitutively secrete bone morphogenetic protein and activin membrane-bound inhibitor (BAMBI), which is subsequently delivered to the liver via the gut-liver axis to therapeutically antagonize liver fibrosis. Methodologically, liver fibrosis was induced in mice via 6-week intraperitoneal injections of thioacetamide (TAA), followed by a 19-week daily oral gavage of live Bs-BAMBI-8 (109 CFU). This longitudinal intervention achieved sustained intestinal colonization (>105 CFU) and BAMBI translocation via the gut-liver axis. This intervention significantly reduced hepatic fibrosis, evidenced by decreased NAFLD Activity Score from six to four and regression of fibrosis stage from S3 to S2. Mechanistically, BAMBI acted as a decoy receptor for transforming growth factor-beta (TGF-β), inhibiting TGF-β signaling and downregulating fibrotic markers (α-smooth muscle actin, collagen I, phosphorylated focal adhesion kinase). This suppression disrupted ECM-mediated mechanotransduction pathways, attenuating hepatic stellate cell activation. Concomitantly, serum markers (alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, total bilirubin) recovered, while albumin synthesis and platelet count recovered. Crucially, this engineered microbiome-based approach integrates synthetic biology with mechanobiology to simultaneously target biochemical signaling and mechanical transduction. It establishes a potentially translatable paradigm for chronic liver disease therapy.","42183858":"ID: 42183858\nTitle: Metformin-phytochemical combination therapy in metabolic dysfunction-associated steatotic liver disease: mechanistic insights and therapeutic potential.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a multifactorial metabolic disorder characterized by excessive hepatic lipid accumulation, insulin resistance, oxidative stress, and chronic inflammation. Its pathogenesis spans interconnected metabolic, inflammatory, and fibrotic pathways, limiting the efficacy of single-target therapeutic approaches. Metformin (MET), a first-line antidiabetic agent, improves hepatic lipid metabolism primarily through AMPK activation and enhanced fatty acid oxidation; however, its therapeutic impact on inflammatory and redox pathways remains limited, and its use is frequently associated with gastrointestinal adverse effects. In this context, phytochemicals-diverse plant-derived bioactive compounds with pleiotropic metabolic and antioxidant properties-have emerged as promising adjuncts to MET to achieve broader pathway coverage. For the first time, this comprehensive review evaluates preclinical in vivo evidence on metformin-phytochemical combination therapy in in vivo models of MASLD, with a specific focus on its mechanistic and therapeutic advantages over monotherapy. A comprehensive literature search was conducted using PubMed, Scopus, Web of Science, and Google Scholar. Only original preclinical in vivo studies evaluating the combination of metformin with an isolated phytochemical in animal models of MASLD were included. Data were extracted on compound identity, dosing regimens, experimental models, and metabolic, inflammatory, and signaling outcomes. Across eligible studies, metformin-phytochemical combinations consistently demonstrated superior efficacy compared with monotherapy in reducing hepatic steatosis, oxidative stress, and inflammatory mediators. Combinations involving berberine, chlorogenic acid, genistein, malvidin, morin, silymarin, and p-coumaric acid were associated with improved energy metabolism and fatty acid β-oxidation, alongside suppression of lipogenesis and fibrotic signaling. Additional benefits reported across studies included modulation of adipose tissue metabolism, enhancement of autophagy-related pathways, and favorable effects on gut-liver axis signaling, depending on the phytochemical class and experimental context. Overall, the preclinical in vivo evidence indicates that metformin-phytochemical cotherapy provides a multipathway modulatory framework integrating metabolic, anti-inflammatory, and antifibrotic effects. These findings support the translational potential of this combination strategy; however, well-designed clinical studies are required to assess pharmacokinetic compatibility, optimize dosing ratios, and determine its relevance in human MASLD.","42184637":"ID: 42184637\nTitle: Effects of modified corn straw dietary fiber on antioxidant status, gut health and lipid metabolism in broilers fed a high-fat diet.\nAbstract: Hepatic abnormal fat accumulation may induce metabolic dysfunction, whereas dietary fiber is proven to reduce body fat deposition. Corn straws, rich in lignocellulose, are a potential source of dietary fiber. This study explored the effects of modified corn straw dietary fiber (MCDF) on broilers fed a high-fat diet and its regulatory mechanisms in lipid metabolic disorders. A total of 150 one-day-old Arbor Acres (AA) broilers were randomly assigned to three experimental groups: control group (basal diet), group 1 (high-fat diet), and group 2 (high-fat diet supplemented with 1% MCDF). The feeding trial was divided into two phases: the early stage (1 to 21d) and the later stage (22 to 42 d). Results showed that groups 1 and 2 exhibited significantly higher ADG and ether extract (EE) metabolism rate at 21 d compared to control group (P < 0.01), whereas feed/gain (F/G) and CP metabolism rate were reduced (P < 0.01). At 42 d, group 2 exhibited a lower F/G compared to the other groups (P < 0.001). MCDF decreased serum levels of TC, TG, ALP, and MDA (P < 0.05), whereas elevated the serum levels of CAT, GSH-Px, IgA, and IgM (P < 0.05). Multi-omics analysis revealed that MCDF reshaped the gut microbiota by increasing the abundance of beneficial taxa (Bacteroidota and Bacteroides) and reducing potentially harmful bacteria (Campylobacterota). These microbial changes were associated with alterations in serum metabolites (arachidonic acid, DHA, DPA, EPA). Furthermore, changes in these metabolites were involved in the regulation of hepatic lipid metabolism by modulating cytochrome P450-related pathways, amino acid metabolism, and key regulatory genes including CYP450, CYP7A1, LTC4S, and PPARα. In conclusion, MCDF alleviated high-fat diet-induced hepatic lipid metabolic disorders through the gut microbiota-metabolite-liver axis. These findings suggest that MCDF, as a functional dietary fiber, has potential applications for improving metabolic health in broilers.","42188051":"ID: 42188051\nTitle: TCM-Derived Natural Compounds Targeting the Gut Microbiota in Metabolic Dysfunction-Associated Steatotic Liver Disease: Gut-Liver Axis Mechanisms, Safety Considerations, and Translational Challenges.\nAbstract: The occurrence and development of metabolic dysfunction-associated steatotic liver disease (MASLD) are closely related to intestinal flora imbalance, intestinal barrier damage, and gut-liver axis dysfunction. Due to their multi-target regulatory effects and advantages in intestinal microecological intervention, Chinese herbal monomers have shown promising application prospects in the prevention and treatment of MASLD. However, basic research on their toxicity still lags behind, and issues related to safety and clinical translation urgently need attention. This article systematically reviews the research progress on how flavonoids, triterpenoids, alkaloids, and polysaccharides improve hepatic steatosis, inflammatory responses, and metabolic disorders from a toxicological perspective by reshaping the intestinal microbiota, repairing the intestinal mucosal barrier, regulating short-chain fatty acid and bile acid metabolism, and synergistically acting on signaling pathways such as TLR4/NF-kB, FXR, TGR5, SIRT1, and the NLRP3 inflammasome. Furthermore, by combining methods such as 16S rRNA sequencing, metagenomics, metabolomics, and multi-omics integration, the article analyzes their application value and limitations in toxicological mechanism research, and discusses the translational bottlenecks faced by Chinese herbal monomers in pharmacokinetics, bioavailability, quality standardization, targeted delivery, and toxicological safety. Existing evidence indicates that Chinese herbal monomers have a three-in-one intervention advantage of microecological remodeling-metabolic regulation-inflammation inhibition, but their long-term medication safety, toxic target organs, dose-effect/toxicity relationships, and potential drug interactions still need further clarification. This article aims to provide a systematic reference for the safety evaluation and clinical translational research of Chinese herbal monomers in the prevention and treatment of MASLD.","42188294":"ID: 42188294\nTitle: Structural Characterization of an α-D-glucan from Bellamya purificata and Its Protective Effects on Non-Alcoholic Fatty Liver Disease in Zebrafish.\nAbstract: Non-alcoholic fatty liver disease (NAFLD) is a primary metabolic disorder that threatens adolescent health globally, with no effective therapeutic agents currently available. Bellamya purificata is a traditional Chinese medicine categorized as \"medicinal food\", and polysaccharides are among its active components. However, its physicochemical structure remains poorly characterized, and no study has evaluated its effects on NAFLD. In this study, a homogeneous neutral polysaccharide, α-D-glucan (Mw = 6412.704 kDa), was isolated from B. purificata. The structure of the polysaccharide was characterized using monosaccharide composition analysis, methylation analysis, NMR spectroscopy, and scanning electron microscopy. The backbone structure of the polysaccharide comprises →4)-α-D-Glcp-(1→ and →4,6)-α-D-Glcp-(1→, with side chains of α-D-Glcp-(1→ attached to the O-6 position of the 1→4,6)-α-D-Glcp-(1→ sugar residues. Additionally, QSPS-1D effectively reduced weight gain, hepatic lipid accumulation (TC and TG), and inflammatory responses (tnf-α and il-1β) in NAFLD zebrafish. Moreover, QSPS-1D alleviated dysbiosis by inhibiting harmful bacteria (e.g., Stenotrophomonas, Agrobacterium, and Chryseobacterium) and promoting beneficial microbiota (e.g., Rothia), which restored the Firmicutes-to-Bacteroidetes ratio. In parallel, it enhanced the expression of tight junction proteins (zo-1 and claudin-1), leading to the repair of the intestinal mucosal barrier. These findings suggest that B. purificata polysaccharides may be a potential functional food for early NAFLD intervention, with effects potentially associated with the modulation of the gut microbiota.","42193367":"ID: 42193367\nTitle: Small Intestinal Bacterial Overgrowth in Metabolic Dysfunction-Associated Steatotic Liver Disease: Prevalence, Subtypes, and Risk Factors Across Disease Spectrum and Comorbidity Profiles.\nAbstract: Background: Small intestinal bacterial overgrowth (SIBO) has been implicated in the pathogenesis of MASLD; however, large-scale clinical data characterizing prevalence patterns, phenotypic subtypes, and disease-specific associations remain limited. Methods: This cross-sectional study enrolled 2549 MASLD patients with gastrointestinal symptoms undergoing lactulose methane-hydrogen breath testing and transient elastography. Univariate and multivariable analysis identified independent risk factors for SIBO. We also explore the distribution of SIBO subtypes and their associations with comorbidity profiles across the MASLD spectrum. Results: The overall prevalence of SIBO was 66.3%, escalating from 65.9% in MASL to 72.8% in at-risk MASH and 78.9% in cirrhosis, alongside a notable enrichment of the intestinal methanogen overgrowth (IMO) phenotype. Multivariable analysis identified advanced fibrosis (stage F4; OR = 1.75, 95% CI: 1.03-2.96), gastroesophageal reflux disease (GERD; OR = 1.66, 95% CI: 1.22-2.28), and coronary artery disease (CAD; OR = 1.80, 95% CI: 1.06-3.06) as independent predictors of SIBO. Additionally, elevated ALT (OR = 1.01, 95% CI: 1.01-1.13) showed a modest association with SIBO. Subtype analysis revealed that IMO was associated with GERD, alcohol consumption, CAD, and obesity, while a history of cholecystectomy and elevated triglycerides were linked to early-phase hydrogen peaks. Conclusions: SIBO is highly prevalent among patients with MASLD, with its prevalence and phenotypic subtype distribution being closely associated with disease severity. The identification of fibrosis-specific risk factors and subtype-clinical associations suggest consideration of SIBO assessment in advanced MASLD, particularly in patients with cardiometabolic or gastrointestinal comorbidities.","42193472":"ID: 42193472\nTitle: Metabolic Dysfunction-Associated Steatotic Liver Disease: An Update Narrative Review of the Therapeutic Potential of Combining Probiotics and Metformin.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) has replaced older exclusion-based terminology as the preferred term for steatotic liver disease associated with cardiometabolic risk factors. MASLD is now among the most common causes of chronic liver disease and may progress from simple steatosis to metabolic dysfunction-associated steatohepatitis (MASH), fibrosis, cirrhosis, and hepatocellular carcinoma. This updated rigorous narrative review synthesizes current evidence on MASLD diagnosis and management, with emphasis on the gut-liver axis and the therapeutic potential of combining probiotics with metformin. A structured narrative search was conducted in PubMed, PMC, ScienceDirect, Taylor & Francis, Cochrane Library, and Google Scholar using the keywords \"MASLD\", \"MAFLD\", \"NAFLD\", \"MASH\", \"probiotics\", \"synbiotics\", \"metformin\", and \"gut-liver axis\". The review was designed as a narrative synthesis rather than a systematic review. Current guidance supports stepwise risk stratification using serum fibrosis scores followed by elastography or advanced imaging when indicated. Ultrasonography remains accessible but has limited sensitivity for mild steatosis, is operator-dependent, and is not sufficient for comprehensive assessment of fibrosis or disease activity. Metformin is appropriate for type 2 diabetes mellitus and improves insulin resistance, but current guidelines do not recommend it as a targeted treatment for MASH because histological benefit has not been consistently demonstrated. Probiotics and synbiotics may improve aminotransferases, inflammatory markers, lipid parameters, intestinal barrier function, and gut dysbiosis; however, findings vary by strain, formulation, dose, treatment duration, population, and endpoint. The combination of probiotics and metformin is mechanistically plausible because it targets both metabolic dysfunction and intestinal dysbiosis, but human evidence remains limited. Larger, strain-specific, adequately powered trials using standardized MASLD criteria and clinically meaningful endpoints are required before routine clinical recommendations.","42196216":"ID: 42196216\nTitle: Experimental Models of Metabolic Dysfunction-Associated Steatotic Liver Disease: A Comparative Analysis of a Choline-Deficient and Cholesterol-Enriched Diet in Rats.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a widespread pathology requiring adequate preclinical models for studying pathogenesis and evaluating therapeutic and preventive agents. This study compared differential markers of MASLD pathogenesis in rats using two distinct dietary models: a choline-deficient high-fat diet (HFD-CD) and a cholesterol-enriched high-fat diet (HFD+CHOL). Male Wistar rats were fed either a control AIN93M diet, HFD-CD (40% fat, 20% fructose, and choline deficiency), or HFD+CHOL (40% fat, 20% fructose, and 1% cholesterol) for 56 days. Comprehensive assessment included phenotypic, biochemical, hematological, histomorphological parameters, oxidative stress markers, hepatocyte apoptosis, cytokine levels, and hepatic gene expression. HFD-CD induced steatosis with moderate insulin resistance, increased malondialdehyde levels, and suppressed Acaca, Scd and ChREBP gene expression. In contrast, HFD+CHOL caused macrovesicular steatosis, inflammation, early fibrosis, atherogenic dyslipidemia, intrahepatic cholesterol accumulation, hepatocyte apoptosis, upregulated Srebf1, Cyp7a1, and Nfkb1 expression, and activated Nrf2-dependent antioxidant responses. HFD-CD and HFD+CHOL induce two pathogenetically distinct MASLD phenotypes. The HFD-CD model, characterized by steatosis and oxidative stress without pronounced inflammation or fibrosis, is preferable for studying the preventive potential of bioactive food compounds. Conversely, the HFD+CHOL model with inflammatory and fibrotic components is more suitable for evaluating therapeutic agents aimed at mitigating inflammation, restoring cholesterol homeostasis, and attenuating fibrosis.","42196250":"ID: 42196250\nTitle: Integrative Multi-Omics Reveal Silibinin Alleviates Heat Stress-Driven Hepatic Lipid Disruption in Laying Hens.\nAbstract: Heat stress (HS) has emerged as a major environmental stressor, inducing oxidative stress and hepatic steatosis and impairing production performance and health in laying hens, with limited evidence-based nutritional interventions available. This study investigated the hepatoprotective effects of dietary silibinin (SIL) against chronic HS. In a 10-week trial, 252 43-week-old Hy-Line Brown hens were exposed to daily HS (32 ± 1 °C, temperature-humidity index [THI] > 73) and fed either a basal diet or one supplemented with 100 mg/kg SIL. SIL significantly increased laying rate (p < 0.05) and improved albumen height, Haugh units, and shell strength by week 8 (p < 0.05). Histological analysis showed a 48% reduction in non-alcoholic fatty liver disease (NAFLD) activity score, with significantly decreased hepatic triglyceride content (p < 0.05); Oil Red O staining confirmed reduced lipid droplet accumulation. SIL restored redox balance by increasing plasma, hepatic total superoxide dismutase (T-SOD), and glutathione peroxidase (GSH-Px) (p < 0.05), increasing hepatic catalase (CAT) and glutathione (GSH) levels while decreasing malondialdehyde (MDA) (p < 0.05). Untargeted plasma metabolomics identified 11 key metabolites related to 2-oxoglutarate and purine metabolism, while hepatic transcriptomics revealed 835 differentially expressed genes primarily in the PPAR signaling and fatty acid biosynthesis pathways. SIL suppressed de novo lipogenesis via downregulation of ACACA and FASN, and enhanced β-oxidation through upregulation of CPT1A and ACSL1 (p < 0.05). Molecular docking indicated favorable binding affinities between SIL and these targets, which was further supported by corresponding changes in protein expression via Western blotting. Correlation analysis revealed a consistent alignment between the upregulation of ACSL1/CPT1A and improvement in performance and antioxidant status, suggesting a coordinated metabolic shift. These findings emphasize the potential of SIL as a sustainable animal nutrition antioxidant additive, which can alleviate HS-induced lipid disorders in the liver of laying hens. Importantly, these hepatoprotective effects were demonstrated exclusively under chronic heat stress conditions; further studies incorporating a normothermic baseline are required to distinguish stress-specific mitigation from general metabolic stimulation.","42196377":"ID: 42196377\nTitle: Integrated Network Pharmacology and Gut Microbiota Analysis Reveals the Alcoholic Extract of Anacyclus pyrethrum Root Prevents Nonalcoholic Fatty Liver Disease via the LPS/TLR4/NF-κB Pathway.\nAbstract: The global incidence of nonalcoholic fatty liver disease (NAFLD) is rising, with no approved pharmacotherapy available. Medicinal plants offer a potential preventive strategy. Anacyclus pyrethrum root exhibits anti-inflammatory and glucose-regulating properties, but its role in NAFLD prevention is unclear. This study aims to investigate the preventive effect of Anacyclus pyrethrum root ethanol extract (APE) against NAFLD and its underlying mechanisms. The chemical composition of APE was analyzed by UHPLC-HRMS. Network pharmacology predicted the potential signaling pathways underlying its protective effects against NAFLD. In a 12-week high-fat diet mice model, APE treatment led to measurements of blood glucose, lipid profiles, liver function parameters, histopathological changes in liver and colon, and gut microbiota alterations via 16S rDNA sequencing. In animal experiments, APE lowered fasting and random blood glucose, total cholesterol, triglycerides, LDL-C, AST, ALT, and serum lipopolysaccharide while increasing HDL-C, and alleviated hepatic steatosis. Network pharmacology suggested APE acts via TLR, NF-κB, and TNF pathways. In vivo, APE suppressed hepatic TLR4, MyD88, p-NF-κB p65, the p-NF-κB p65/NF-κB p65 ratio, and TNF-α/IL-6 levels. Gut microbiota analysis showed increased Akkermansiaceae and decreased Desulfovibrionaceae. APE also upregulated intestinal Occludin and ZO-1, and downregulated intestinal TNF-α and IL-6. APE prevents NAFLD progression, potentially by regulating gut microbiota, protecting the intestinal mucosal barrier, and inhibiting the LPS/TLR4/MyD88/NF-κB pathway.","42208803":"ID: 42208803\nTitle: Maximization of mitochondrial fatty acid oxidation by co-administration of PPARα agonist and peroxisomal β-oxidation inhibitor.\nAbstract: PPARα plays a pivotal role in regulating hepatic fatty acid oxidation and activation of PPARα has been well known to stimulate mitochondrial β-oxidation and has the potential to reduce hepatic lipid level, while evidences indicate that administration of PPARα agonist does not affect hepatic triglyceride level. Therefore, an alternative mechanism might work to counteract the lipid-lowering effect of PPARα agonist. As fatty acids can also be metabolized in peroxisome and the acetyl-CoA generated in peroxisomal β-oxidation could be used for the biosynthesis of malonyl-CoA, a critical molecule in controlling mitochondria fatty acid oxidation. We hypothesize that peroxisomal β-oxidation might play a role in regulating mitochondrial fatty acid oxidation through mediating malonyl-CoA formation. This study demonstrates a counteracting mechanism by which induction of peroxisomal β-oxidation causes suppression of mitochondrial fatty acid oxidation in animals administered with PPARα agonist. PPARα agonist induces oxidation of fatty acids by peroxisomes and generates considerable acetate in the liver, which significantly elevates hepatic content of malonyl-CoA, and causes suppression of mitochondrial β-oxidation. Specific inhibition of peroxisomal β-oxidation enhances mitochondrial fatty acid oxidation and attenuates hepatic lipid accumulation by reducing acetate and malonyl-CoA formation in the mice treated with PPARα agonist. It is suggested that combination therapy of PPARα agonist and peroxisomal β-oxidation inhibitor might be a novel and effective treatment of fatty liver and related metabolic disorder through maximization of mitochondrial fatty acid oxidation.","42208886":"ID: 42208886\nTitle: Perfluoroalkyl and polyfluoroalkyl substances exposure and liver disease: A review.\nAbstract: Per- and polyfluoroalkyl substances (PFASs) are widely used in numerous industrial processes and consumer products and are now ubiquitously distributed in the environment, thereby creating multiple routes of human exposure. Their physicochemical properties confer high persistence, bioaccumulation potential, and toxicity, which have raised increasing concern about their long-term impacts on human health. Because of its central role in xenobiotic uptake, metabolism, transport, and excretion, the liver is considered a major target organ of PFAS toxicity. Over the past few years, a growing body of epidemiological, in vivo, and in vitro evidence has linked PFAS exposure to a broad spectrum of hepatic abnormalities, including liver injury, cholestatic liver injury and bile acid dysregulation, metabolic dysfunction-associated steatotic liver disease (MASLD), and hepatocellular carcinoma (HCC). In addition to legacy long-chain PFASs, short-chain congeners and emerging alternatives such as GenX and 6:2 Cl-PFESA have also shown considerable hepatotoxic potential. This review summarizes current evidence on the contribution of PFAS exposure to liver disease, with particular attention to human relevance and the mechanisms underlying PFAS-induced hepatotoxicity, including oxidative stress, inflammatory activation, disruption of the gut-liver axis and enterohepatic circulation, lipid metabolic reprogramming, and impairment of bile acid homeostasis. Remaining knowledge gaps and future perspectives are also highlighted to support mechanistic understanding and improve PFAS-related liver risk assessment.","42216291":"ID: 42216291\nTitle: Adipose Tissue Inflammation, Oxidative Stress, and Altered Adipogenesis Are Associated With Dyslipidemia in Obesity: A Multiomics Profiling Study.\nAbstract: Obesity is an important risk factor for cardiometabolic disease, including dyslipidemia and atherosclerotic cardiovascular disease. Although the role of the liver in dyslipidemia is established, the contribution of adipose tissue is less clear. This study aims to clarify the role of adipose tissue in lipid metabolism and dyslipidemia. We conducted a cross-sectional analysis of 125 patients from the BARIA (The Immune System and Microbial Tone in Relation to NAFLD/NASH Before and After Bariatric Surgery in the Morbidly Obese in Amsterdam) longitudinal cohort study undergoing bariatric surgery. Comprehensive phenotyping included fasting untargeted plasma metabolomics, lipid, lipoprotein, adipokine profiling, RNA sequencing, and fecal shotgun metagenomics. Tissue transcriptomic and plasma metabolites were compared between individuals with and without dyslipidemia. Dyslipidemia was present in 43 of 125 individuals (34.4%), with higher triglycerides (1.62 versus 1.24 mmol/L), apoB (apolipoprotein B; 93.15 versus 81.81 mg/dL), and lower high-density lipoprotein (1.02 versus 1.35 mmol/L) and apoAI (136.40 versus 161.35 mg/dL). Plasma adipokines showed limited differences: leptin concentrations were lower in dyslipidemia in unadjusted analysis but reduced after adjustment for age, sex, and body weight (adjusted P=0.057). RNA sequencing identified altered gene expression of liver, jejunum, visceral and subcutaneous adipose tissue, most pronounced in subcutaneous adipose tissue. Dyslipidemia was associated with adipose tissue pathways related to inflammation, oxidative stress, and adipogenesis. Plasma metabolomics revealed associations with endocannabinoid-like, secondary bile acid, plasmalogen, butyrate, and sphingolipid metabolites. Gut metagenome analysis found modest differences. Dyslipidemia in obesity is associated with transcriptomic alterations in adipose tissue, including subcutaneous adipose tissue, involving inflammation, oxidative stress, and adipogenesis. These findings support a role of adipose tissue in lipid regulation beyond hepatic pathways.","42217069":"ID: 42217069\nTitle: Therapeutic effects of chitooligosaccharide-epigallocatechin gallate conjugate on NAFLD: impact on gut-liver axis, lipid metabolism, and inflammation in rats fed a high-fat diet.\nAbstract: Non-alcoholic fatty liver disease (NAFLD) is a progressive disorder correlated with hepatic lipid homeostasis, gut dysbiosis, and inflammation. In this study, we propose a novel dietary therapy for NAFLD utilizing a conjugate of chitooligosaccharide (COS) and epigallocatechin gallate (EGCG), as the underlying mechanisms of NAFLD remain unclear. NAFLD was induced in male Wistar rats by administering a high-fat diet (HFD) for 16 weeks, followed by administration of COS-EGCG conjugate (150, 300, and 600 mg/kg) for an additional four weeks. The treatment alleviated metabolic parameters, liver steatosis, and injury. It also reduced hepatic lipid accumulation by downregulating the expression of CD36, fatty acid synthase (FASN), and sterol regulatory element-binding protein 1c (SREBP-1c), while upregulating peroxisome proliferator-activated receptor alpha (PPARα), carnitine palmitoyltransferase 1 A (CPT1A), and microsomal triglyceride transfer protein (MTTP). Regarding the gut-liver axis, the conjugate modulated gut microbiota, reduced serum lipopolysaccharide (LPS) levels, and restored the expression of intestinal tight junction proteins (zonula occludens-1; ZO-1 and occludin). It also prevented liver inflammation induced by gut-derived LPS by suppressing the Toll-like receptor 4 (TLR4)/nuclear factor kappa B (NF-κB) signaling pathway. The results suggest that the COS-EGCG conjugate exerts therapeutic effects against NAFLD by regulating hepatic lipid metabolism, modulating the gut microbiota, and attenuating gut-derived LPS-induced liver inflammation.","42217150":"ID: 42217150\nTitle: Lactobacillaceae in Acute and Chronic Liver Diseases: From Microbiota Modulation to Therapeutic Potential.\nAbstract: Liver diseases, including metabolic-associated fatty liver disease (MAFLD), alcoholic liver disease (ALD), and viral hepatitis, are highly prevalent and constitute a major global health burden. Accumulating evidence indicates that dysbiosis of the gut microbiota is closely associated with the development and progression of various liver diseases. Among microbial regulators, Lactobacillaceae, a family of probiotic lactic acid bacteria, has attracted considerable attention for its capacity to reshape the gut microbiota, strengthen mucosal barrier integrity, modulate nutrient metabolism, and regulate both innate and adaptive immune responses. A growing body of evidence has shown that members of the Lactobacillaceae family can alleviate hepatic inflammation, reduce steatosis, and modulate gut-derived metabolic pathways involving bile acids, lactate, and short-chain fatty acids. This review provides a comprehensive overview of the role of Lactobacillaceae in acute and chronic liver diseases, examines the mechanisms by which this family influences liver diseases through the gut-liver axis, and highlights future directions for microbiota-based therapeutic strategies.","42221502":"ID: 42221502\nTitle: Therapeutic potential of natural compounds from medicinal and food homology substances targeting gut microbiota in lipid metabolism disorders.\nAbstract: Dyslipidemia contributes to chronic diseases such as non-alcoholic fatty liver disease (NAFLD), type 2 diabetes (T2DM), and obesity. Emerging evidence highlights gut dysbiosis as a key driver of abnormal lipid metabolism. This review examines how natural bioactive compounds from medicinal and food homology (MFH) substances regulate lipid metabolism by modulating the gut microbiome. It summarizes evidence on the modification of the microbiota-lipid metabolism axis by natural compounds from MFH substances and discusses the limitations of applications and their promise for preventing and treating metabolic diseases. By capitalizing on these microbiota-mediated effects, natural compounds may serve as a beneficial natural resource for adjusting lipid metabolism.","42221532":"ID: 42221532\nTitle: Fecal microbiota transplant and its usefulness in hepatic disorders: a systematic review.\nAbstract: Fecal microbiota transplantation (FMT) is an emerging therapeutic approach aimed at restoring gut microbial balance through the transfer of stool from healthy donors. It has gained significant attention for its role in managing gut dysbiosis-associated disorders, particularly hepatic diseases. This systematic review evaluated the therapeutic efficacy and clinical potential of FMT in the management of liver-related conditions, including recurrent Clostridium difficile infection (CDI), non-alcoholic fatty liver disease, liver cirrhosis, and hepatic encephalopathy. A systematic review of existing literature was conducted to assess the clinical outcomes, mechanisms, and challenges associated with FMT in hepatic disorders. Relevant studies were identified from peer-reviewed scientific databases, focusing on clinical trials, observational studies, and experimental research investigating the role of FMT in gut dysbiosis and liver disease. Data were analyzed to evaluate efficacy, underlying mechanisms, and safety considerations. FMT demonstrated high efficacy in recurrent CDI, with cure rates exceeding 80%-90%. In hepatic disorders, FMT was associated with improved microbial diversity, enhanced gut barrier integrity, and reduced systemic inflammation, contributing to better liver function and clinical outcomes. However, variability in donor selection, potential safety risks, and regulatory limitations remain significant challenges. FMT represents a promising therapeutic strategy in hepatology, underscoring the critical role of the gut-liver axis. Advances such as synthetic microbiota and personalized microbiome-based therapies may further optimize its safety and efficacy, paving the way for innovative, microbiome-centered interventions in liver disease management.","42223079":"ID: 42223079\nTitle: Chronic Liver Disease, Liver Damage and Liver Failure After Hypoabsorptive Bariatric Surgery: A Dose-Dependent Relationship and Multisystemic Consequences.\nAbstract: Metabolic bariatric surgery remains the most potent weapon we have against severe obesity and its metabolic consequences. Yet, its effects on the liver are far from uniform. Although restrictive and mixed procedures like sleeve gastrectomy and Roux-en-Y gastric bypass consistently improve metabolic dysfunction-associated steatotic liver disease (MASLD), hypoabsorptive operations carry a distinct and troubling risk of progressive liver injury. The available evidence, drawn predominantly from case series, registry data and retrospective analyses, suggests that this risk is not an all-or-nothing phenomenon but instead follows a conceptual gradient, one that correlates with the degree of intestinal malabsorption and, more specifically, with the extent of bile acid malabsorption. This review traces the evidence for this dose-dependent relationship from the historical disaster of the jejunoileal bypass to contemporary procedures like the biliopancreatic diversion and the single-anastomosis duodenal-ileal bypass. We explore the pathophysiological triad that drives this process-protein-energy malnutrition, bacterial overgrowth, and bile acid hepatotoxicity-supported by recent experimental evidence directly linking biliary limb length to liver injury. The review then contextualizes the discussion within associated multisystemic consequences, including de novo inflammatory bowel disease, severe metabolic bone disease, and a distinct discussion of the accelerated alcohol-associated liver disease that follows bariatric surgery. A synthesis of the available evidence supports the abandonment of a one-size-fits-all approach in favour of meticulous patient selection, precise and individualized surgical technique based on measured bowel length and a commitment to lifelong, intensive, multidisciplinary postoperative surveillance. Hypoabsorptive bariatric procedures carry a dose-dependent risk of progressive liver injury mediated by malabsorption, bacterial overgrowth and bile acid hepatotoxicity, necessitating individualized surgical planning and lifelong follow-up.","42231130":"ID: 42231130\nTitle: Green synergistic non-thermal processing of Xinhui Chenpi: targeted fraction screening and mechanistic elucidation of antioxidant enhancement in Caenorhabditis elegans.\nAbstract: Xinhui Chenpi (CP) is rich in polyphenols and flavonoids with excellent bioactivity, but its high-value biomass utilization is restricted. Green non-thermal processing can effectively maintain the structural integrity of bioactive small molecules, which is promising for the efficient valorization of CP resources. However, targeted preparation of high-activity CP fractions and their in vivo antioxidant mechanisms, as well as potential targets against alcoholic fatty liver (AFL), remain poorly clarified. A high-activity CP fraction (CPSU-H) was selectively prepared via pulsed electric field-ultrasonic synergistic extraction, ethanol polarity grading fractionation and HPD100 macroporous resin adsorption purification. CPSU-H significantly reduced malondialdehyde content to 0.32 ± 0.07 nmol mg protein-1 in Caenorhabditis elegans, and increased total superoxide dismutase, glutathione peroxidase and catalase activities to 80.35 ± 2.15, 148.73 ± 9.05 and 9.74 ± 0.52 U mg protein-1, respectively, showing strong in vivo antioxidant enhancement under non-stressed conditions. CPSU-H was dominated by neohesperidin and narirutin; nucleocytoplasmic transport pathway, longevity regulating pathway and nucleotide metabolism pathway were speculated to serve as the core signaling and metabolic pathways for its antioxidant enhancement. In addition, it could exert potential intervention effect on AFL through targeting proteins PTGS2, TNF, SRC, MMP9 and EGFR. This study realizes the directional green preparation of CPSU-H and clarifies its antioxidant mechanism under non-stressed conditions and AFL-related target proteins. The findings support the potential development of CPSU-H as natural antioxidants and functional food components, and provide a theoretical basis for high-value utilization of CP biomass and extended application of synergistic non-thermal processing technologies. © 2026 Society of Chemical Industry.","42233026":"ID: 42233026\nTitle: Resveratrol ameliorates intrahepatic cholestasis of pregnancy by modulating the gut-liver axis and FXR-mediated bile acid homeostasis.\nAbstract: Intrahepatic cholestasis of pregnancy (ICP) is a liver disorder with limited treatment options. This study investigated the therapeutic potential of resveratrol (RES) and its underlying mechanisms, focusing on the gut-liver axis and bile acid metabolism in an estrogen-induced ICP rat model. Pregnant rats were randomized into Sham, ICP (induced by 17β-estradiol), and ICP+RES (15, 30, 60 mg/kg) groups. Systemic and hepatic inflammation, liver function, histopathology, and intestinal barrier integrity were assessed. Hepatic bile acid profiles were analyzed by UHPLC-MS/MS, and gut microbiota was evaluated by 16S rRNA sequencing. The role of gut microbiota was further examined via fecal microbiota transplantation (FMT) in pseudogerm-free rats. Key proteins in the FXR signaling pathway were analyzed by Western blotting. RES treatment dose-dependently alleviated ICP manifestations, including reducing serum levels of total bile acids, total bilirubin, and liver enzymes (AST, ALT, ALP), while mitigating systemic and hepatic inflammation. It also restored intestinal barrier integrity and corrected gut microbiota dysbiosis. FMT from RES-treated donors recapitulated these therapeutic effects in recipient ICP rats. Furthermore, RES reversed the hepatic bile acid imbalance by reducing primary bile acids and increasing beneficial secondary bile acids. Mechanistically, RES upregulated the expression of FXR and its downstream targets, including SHP, BSEP, UGT2B4, and CYP1A1. RES effectively ameliorated ICP through multi-faceted mechanisms involving the attenuation of inflammation, restoration of gut microbiota and intestinal barrier, and correction of bile acid homeostasis via activation of the FXR signaling pathway. Our findings highlight RES as a promising multi-mechanistic therapeutic candidate for ICP.","42240574":"ID: 42240574\nTitle: Camellia diacylglycerol oil attenuates atherosclerosis and NAFLD by modulating gut microbiota and lipid metabolism in ApoE-/- mice.\nAbstract: Camellia diacylglycerol oil (CDO), produced by enzymatic glycerolysis of camellia oil, is widely consumed as a functional food ingredient; however, its cardiovascular benefits remain insufficiently characterized. This study investigated the effects of CDO on high-fat diet (HFD)-induced atherosclerosis and non-alcoholic fatty liver disease in ApoE-/- mice, with a particular focus on alterations in gut microbiota and metabolomic profiles. Compared with the vehicle group, CDO supplementation (3 and 6 mL kg-1) reduced aortic plaque area by approximately 50% without significantly affecting body weight in the mice. CDO treatment significantly decreased serum triglycerides (TG), total cholesterol (TC) and low-density lipoprotein cholesterol, at the same time as increasing high-density lipoprotein cholesterol. Notably, CDO administered at 3 mL kg-1 demonstrated greater efficacy than camellia oil in improving TG and high-density lipoprotein cholesterol levels (P < 0.05). Furthermore, CDO supplementation significantly alleviated hepatic histopathological injury, reduced Oil Red O-positive lipid deposition and lowered hepatic TG and TC levels compared to the vehicle group. Gut microbiota analysis revealed a decreased Firmicutes/Bacteroidetes ratio and increased relative abundances of Roseburia and Faecalibaculum in CDO-treated mice. Metabolomic profiling further identified ether lipid metabolism and bile acid-related pathways as potential mediators of the metabolic improvements-induced by CDO. CDO was more effective than camellia oil in mitigating HFD-induced atherosclerosis and non-alcoholic fatty liver disease in ApoE-/- mice, most likely through coordinated modulation of the gut-liver-vascular axis. These findings support the potential of CDO as a functional food ingredient for cardiovascular risk reduction and warrant further validation in human studies. © 2026 Society of Chemical Industry.","42242027":"ID: 42242027\nTitle: Bifidobacterium longum alleviation of metabolic dysfunction-associated steatotic liver disease: A multi-omics landscape of microbiota and metabolome reconfiguration.\nAbstract: The gut microbiome-host metabolism axis plays a critical role in the pathogenesis of metabolic dysfunction-associated steatotic liver disease (MASLD). Although the probiotic Bifidobacterium longum (B. longum) shows promise in ameliorating metabolic disorders, its functional impact on the microbiome-metabolome interplay in MASLD remains elusive. Herein, we established a MASLD mouse model using a high-fat, high-fructose (HFHF) diet and conducted integrated multi-omics analyses, including liver transcriptomics, gut metagenomics, and serum metabolomics, following B. longum intervention. B. longum supplementation effectively attenuated systemic metabolic dysfunction, hepatic steatosis, and intestinal barrier impairment in MASLD. This amelioration was driven by a two-pronged functional reorganization: the restoration of intestinal integrity and a profound remodeling of the hepatic transcriptome, featuring the downregulation of crucial mediators within the CD14-TLR4-NF-κB signaling cascade, including Cd14 and Runx1. Such functional reorganization coincided with a reconfigured gut microbiota, characterized by an increased abundance of beneficial taxa (e.g., Parabacteroides distasonis, Muribaculum intestinale) and suppression of opportunistic pathobionts (e.g., Ruminococcus gnavus, Clostridioides difficile). Furthermore, these microbial shifts were intrinsically linked to a reconfigured serum metabolome, highlighted by the enrichment of protective tryptophan-derived metabolites (e.g., indole-3-propionic acid) and the reduction of detrimental ones (e.g., 17α-methyltestosterone, 7-HDoHE). Collectively, our results suggest that B. longum mitigates MASLD through modulation of the gut microbiota and host serum metabolome, supporting its potential as a probiotic candidate for the management of metabolic health.","42242572":"ID: 42242572\nTitle: Liver-brain axis mechanism underlying central immune remodeling triggered by peripheral hepatic damage.\nAbstract: Liver dysfunction and various hepatic disorders cause neuropsychiatric abnormalities including depression, anxiety, cognitive impairment and personality changes through liver-brain axis imbalance, greatly worsening patient prognosis. The liver-brain axis acts as a bidirectional network via neural, humoral, immune and gut microbiota pathways, and its disruption dominates liver disease-related central nervous system (CNS) injury. Toxic metabolites such as bilirubin activate the transient receptor potential cation channel subfamily M member 2 (TRPM2)-spleen tyrosine kinase (SYK)-nuclear factor kappa-B (NF-κB) pathway in microglia, triggering excessive glutamatergic synapse phagocytosis in the anterior cingulate cortex (ACC) and sustained neuroinflammation with irreversible neural circuit damage. This review summarizes the pathogenesis of neuropsychiatric complications induced by liver dysfunction and liver transplantation, focusing on blood-brain barrier (BBB) disruption, systemic immune activation, neurotransmitter imbalance and resident immune cell phenotypic shifts. It clarifies four liver-brain axis regulatory pathways, highlights microglial central functions, and addresses gut-liver-brain axis crosstalk, meningeal immunity, choroid plexus barrier damage and circadian rhythm disturbance. It also concludes diagnostic biomarkers including bilirubin and fibroblast growth factor 21 (FGF21), alongside therapeutic targets covering the TRPM2-SYK-NF-κB pathway, microglial polarization and gut microbiota. This study provides a unified theoretical framework for clinical diagnosis, risk stratification and targeted treatment of liver disease-related neuropsychiatric complications, and explains CNS dysfunction mechanisms underlying metabolic dysfunction-associated steatotic liver disease (MASLD), liver cirrhosis and acute-on-chronic liver failure.","42245952":"ID: 42245952\nTitle: The immunometabolic mechanisms and therapeutic targets of metabolic dysfunction-associated steatohepatitis.\nAbstract: Metabolic dysfunction-Associated Steatohepatitis (MASH) is a progressive subtype of Metabolic dysfunction-Associated Steatotic Liver Disease (MASLD) characterized by hepatic steatosis, inflammation, hepatocellular injury, and fibrosis, which may evolve to cirrhosis and hepatocellular carcinoma. Despite its growing global burden, no widely approved pharmacotherapy is available, highlighting the need to elucidate immunometabolic mechanisms and identify effective therapeutic targets. This review summarizes the epidemiology and clinical features of MASH and focuses on key pathogenic pathways, including insulin resistance, lipotoxicity, mitochondrial dysfunction, and gut-liver axis disturbance. Immune dysregulation mediated by Kupffer cell activation, macrophage polarization, inflammasome signaling, and cytokine networks is discussed in depth. The critical role of immunometabolic crosstalk in disease progression is emphasized. Current and emerging therapeutic targets-such as PPARs, FXR, THR-β, the GLP-1/FGF21 axis, DGAT2, and CCR2/CCR5-are systematically reviewed, together with advances in oligonucleotide therapy, cell-based interventions, and combination strategies. MASH results from the complex coupling of metabolic imbalance and immune-driven inflammation, making single-target therapy insufficient. Precision stratification based on immunometabolic networks and multi-target interventions represent promising directions for future drug development and individualized treatment.","42249406":"ID: 42249406\nTitle: Safety and metabolic effects of HTD1801 in type 2 diabetes and MASLD: a phase Ib randomized trial.\nAbstract: HTD1801 is a novel compound composed of equal parts berberine (BBR) and ursodeoxycholic acid (UDCA). It functions as a gut-liver metabolic modulator with a unique mechanism of action that may offer therapeutic benefits for patients with type 2 diabetes mellitus (T2DM) and metabolic dysfunction-associated steatotic liver disease (MASLD). A total of 48 patients were enrolled in this study. Thirty-six treatment-naïve patients were randomized to receive HTD1801 at doses of 500 mg, 750 mg, or 1000 mg, or placebo, administered twice daily for 28 days. An additional 12 patients on stable metformin therapy were randomized (3:1) to receive either HTD1801 1000 mg or placebo. HTD1801 was generally well tolerated, with most adverse events classified as mild to moderate in severity. No serious adverse events were reported. Berberine exhibited saturation kinetics, whereas UDCA demonstrated linear pharmacokinetics. Accumulation was low to moderate (range: 0.9673 to 2.6659). Compared to placebo, HTD1801 improved glucose and lipid metabolism and reduced liver enzyme levels. A dose-dependent effect was observed, with metabolic improvements increasing with higher administered doses. In the metformin group, HTD1801 (1000 mg) resulted in greater reductions in fasting glucose (mean absolute decrease: -1.271 vs. +0.423 mmol/L), 2-h postprandial glucose (-4.167 vs. +0.290 mmol/L), LDL-C (-0.623 vs. +0.290 mmol/L), total cholesterol (-1.090 vs. +0.023 mmol/L), and GGT (-9.28 vs. -4.43).

Triterpenoids, particularly ganoderic acids, represent the principal bioactive constituents in Ganoderma lucidum. Bacteria-enzyme synergistic fermentation broth of Ganoderma lucidum (FBG) was optimized as a potential alternative to traditional water-extracted Ganoderma lucidum (WEG). The optimized parameters with Lactobacillus rhamnosus fermentation exhibited the highest content of ganoderic acid F (GAF). Administration of FBG led to a pronounced decline in lipid deposition and contents of intracellular total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), reactive oxygen species (ROS), and malonic dialdehyde (MDA). The FBG treatment also markedly increased the activities of high-density lipoprotein cholesterol (HDL-C), superoxide dismutase (SOD), and catalase (CAT). The results of network pharmacology analysis and molecular docking suggested that GAF exhibits a robust interaction with the core targets sodium leak channel, nonselective (NALCN) and eukaryotic translation elongation factor 1 alpha 2 (EEF1A2). Enzyme-linked immunosorbent assay (ELISA) results demonstrated that GAF could effectively reduce lipid accumulation while upregulating EEF1A2, phosphorylated AMP-activated protein kinase (p-AMPK), and peroxisome proliferator-activated receptor alpha (PPAR-α) protein expression. Collectively, these findings indicate that GAF alleviates free fatty acid (FFA)-induced hepatic lipid accumulation through activation of the EEF1A2/p-AMPK/PPAR-α signaling pathway, suggesting a potential mechanism involving AMPK-related pathways.","42259413":"ID: 42259413\nTitle: A novel pectic polysaccharide from Prunella vulgaris L. and its therapeutic potential in alleviating alcoholic liver injury by regulating lipid metabolism and inflammation.\nAbstract: Prunella vulgaris L. (XiakuCao) is a traditional edible Chinese medicinal herb widely used for its purging properties. While its polysaccharides are known for diverse bioactivities, their potential in treating liver diseases remains closely linked to their specific structural features. Most reported polysaccharides from Prunella vulgaris L. have been complex heteropolysaccharides isolated by hot water. In this study, a new homogeneous polysaccharide, designated AO3-1, was isolated for the first time from Prunella vulgaris L. by ammonium oxalate solution after water treatment. Structural analysis revealed that AO3-1 is mainly composed of α-D-1, 4-GalpA, consistent with a typical pectic polysaccharide. Pharmacological evaluations demonstrated that AO3-1 has significant therapeutic effects in alleviating alcoholic liver injury (ALD), as indicated by the reduction of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels, and the mitigation of hepatic steatosis (TG, TC, LDL-C and HDL-C). Notably, AO3-1 treatment suppressed systemic inflammation (IL-6, IL-1β and TNF-α) and effectively modulated intestinal microecology, suggesting a protective role mediated by the gut-liver axis. These findings provide the first evidence of a unique pectic polysaccharide from Prunella vulgaris L. with potent anti-ALD activity. Our study highlights the potential of AO3-1 as a novel functional food ingredient or therapeutic agent for managing alcoholic liver injury, offering a new strategy for the valorization of herbal processing by-products.","42260527":"ID: 42260527\nTitle: Calculus Bovis ameliorates primary sclerosing cholangitis via a dual-pronged mechanism restoring bile acid and lipid homeostasis in the gut-liver axis.\nAbstract: Primary sclerosing cholangitis (PSC) is a progressive cholestatic liver disease lacking FDA-approved therapy. Calculus Bovis (CB), a traditional medicine derived from animal gallstones, has been historically used for treating hepatobiliary diseases, but its therapeutic potential and mechanisms in PSC remain unexplored. This study aimed to investigate the efficacy of CB in an experimental PSC model and elucidate its underlying mechanisms. A PSC mouse model was induced by a 0.1% 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC) diet for 4 weeks. Mice were treated with CB (50,100, 150 mg/kg/day) or ursodeoxycholic acid (UDCA, 100 mg/kg/day). Liver injury, fibrosis, intestinal barrier integrity, bile acid (BA) profiles, and lipid levels were assessed. Hepatic and intestinal gene/protein expression related to BA and lipid metabolism was analyzed. Integrated transcriptomics, network pharmacology, and in vitro serum pharmacology were employed to elucidate the underlying mechanisms. CB administration significantly alleviated liver injury, fibrosis, and intestinal barrier damage in DDC-induced mice. It restored BA homeostasis across the gut-liver axis, normalizing aberrant BA profiles in serum and liver while increasing BA excretion in feces. CB also ameliorated dyslipidemia, reducing hepatic and serum lipid levels. Mechanistically, CB and its bioactive BA components exerted their effects through a dual-pronged mechanism: (1) activation of the SIRT1-PGC-1α axis to transcriptionally upregulate the expression of nuclear receptors FXR and PPARα in the liver and intestine, and (2) direct ligand-dependent activation of FXR and PPARα protein functions. This concerted activation enhanced the transcription of genes involved in BA detoxification, transport, and fatty acid β-oxidation. Inhibition of SIRT1 or antagonism of FXR/PPARα attenuated these protective effects in vitro. CB attenuates experimental PSC by modulating BA and lipid homeostasis via the gut-liver axis, mediated through a novel dual mechanism involving SIRT1-PGC-1α pathway activation and direct receptor agonism. These findings not only highlight CB as a promising multi-target agent for PSC treatment, but also provide novel insights into the therapeutic modulation of metabolism in the gut-liver axis.","42260857":"ID: 42260857\nTitle: Exploring racial-specific associations between the food inflammation index(FII) and metabolic dysfunction-associated fatty liver disease (MAFLD) Prevalence: Data from the National Health and Nutrition Examination Survey 1999-2020.\nAbstract: The Food Inflammation Index (FII) is a novel indicator for assessing the impact of diet on systemic inflammation. Unlike the Dietary Inflammation Index, which focuses on nutrients, the FII quantifies specific foods, providing greater applicability to real-world dietary assessments. To date, no study has examined the association between FII and the prevalence of Metabolic dysfunction-associated fatty liver disease (MAFLD). This study aimed to investigate the relationship between FII and MAFLD. This cross-sectional study included 25,067 individuals aged ≥ 20 years from the 1999 to 2020 National Health and Nutrition Examination Survey (NHANES). Univariate and multivariate logistic regression analyses were performed to explore the relationship between FII and MAFLD. Nonlinear associations between FII and MAFLD were examined using restricted cubic spline (RCS) analysis. Subgroup analyses, interaction tests, and threshold effect analyses were conducted to assess differences across groups. The prevalence of MAFLD was 44.45%. FII was positively associated with MAFLD in all models (Models 1, 2, and 3, P < .05). In model 3, individuals in the highest tertile of FII had an odds ratio (OR) of 1.21 [95% confidence interval (CI): 1.11-1.32] for MAFLD, compared to those in the lowest tertile. Subgroup analyses and interaction tests revealed sex- and race-specific associations between FII and MAFLD. Among non-Hispanic whites, the optimal FII threshold for preventing MAFLD was found to be -11.56. A lower FII was associated with a lower prevalence of MAFLD. The impact of FII on MAFLD prevalence was more pronounced among non-Hispanic whites compared to other racial groups. An FII score of < -11.56 for daily food intake was associated with a reduced risk of MAFLD in non-Hispanic whites.","42272284":"ID: 42272284\nTitle: Parthenolide ameliorates metabolic dysfunction-associated steatohepatitis by inhibiting M1 polarization by suppressing the nuclear factor-κB pathway.\nAbstract: Metabolic dysfunction-associated steatohepatitis (MASH) is an inflammatory disorder that results in ongoing liver inflammation and injury. During the course of hepatitis, parthenolide (PAR) promotes the recovery of liver function. Using a mouse model of MASH, the present study aimed to assess the effect of PAR on the condition. The MASH mouse model was developed using a high-fat diet combined with high-carbohydrate drinking, and measurements were taken for body weight, liver-to-body mass ratio, non-alcoholic fatty liver disease activity score, and levels of alanine aminotransferase and aspartate aminotransferase. Subsequently, liver injury was detected using hematoxyling and eosin staining, hepatic lipid accumulation was evaluated with oil red O staining, and liver fibrosis was assessed through Masson staining. Macrophage infiltration and M1 polarization were assessed by immunofluorescence staining for F4/80; and lipid metabolic, fibrotic, and pro-inflammatory indicators were detected by RT-qPCR; nuclear factor-κB (NF-κB) signaling pathway was assessed by Western blot. We found that PAR alleviated liver injury, improved lipid metabolism, and reduced fibrosis in MASH mice,. It also lowered macrophage infiltration in the liver, particularly decreasing M1 macrophages and pro-inflammatory cytokines. PAR inhibited the activation of the NF-κB pathway, and the protective effects were attenuated by an NF-κB pathway activators. We conclude that PAR ameliorates liver injury, hepatic lipid metabolism, fibrosis and inflammation in MASH mice, likely by suppressing the NF-κB pathway and thereby inhibiting M1 polarization.","42274538":"ID: 42274538\nTitle: Regulation Progresses of Selenium Improving Intestinal and Extra-Intestinal Tissues Health Through Regulating Gut Microbiota.\nAbstract: Selenium (Se) is an essential trace element that exerts pleiotropic effects on host physiology, yet the mechanisms by which it coordinates systemic health remain incompletely understood. Emerging evidence regards the gut microbiota as a key mediator of Se biological functions, giving rise to the Se-gut-tissue axis. This review synthesizes the current research progresses on how dietary Se may shape gut microbial composition and metabolism, and how these microbial shifts are associated with protective effects in both intestinal and extra-intestinal tissues. Se sources (particularly organic or new synthetic form) may bidirectionally interact with gut bacteria by enriching beneficial genera such as Akkermansia, Lactobacillus, and butyrate-producing Clostridia, while suppressing opportunistic pathogens. This microbial remodeling strengthens intestinal barrier integrity, enhances antioxidant and anti-inflammatory responses (e.g., via GPX, TrxR, and NF-κB suppression), and generates bioactive metabolites, notably short-chain fatty acids and secondary bile acids. Through these mechanisms, the Se-gut-microbiota axis may regulate distal organ homeostasis, including the liver (ameliorating NAFLD and acute injury), brain (counteracting neurodegeneration and modulating serotonin/GABA), muscle (improving mass and Se deposition), kidney (attenuating uremic toxin-induced ferroptosis), and reproductive organs. Despite encouraging progress, challenges remain in establishing causality, optimizing dose-response relationships, and translating findings into precision interventions.","42275581":"ID: 42275581\nTitle: Gut microbiota-derived indole-3-propionic acid alleviates endoplasmic reticulum stress by regulating FMO2 in MASLD.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) has become a global health challenge for which there are currently no approved drugs. Indole-3-propionic acid (IPA), as one of the primary metabolites of gut microbiota, can influence the development of liver diseases through the gut-liver axis, but how it contributes to liver diseases remains unclear. The present study was conducted to explore the possible molecular mechanisms of IPA in the development of MASLD. Metabolomic analysis compared serum and fecal metabolite profiles between MASLD and normal mice. The effects of microbial metabolite IPA on MASLD were evaluated through the utilization of a mouse model and cell models. Transcriptome data analysis was used, and further validation was conducted through flow cytometry, western blotting, RNA interference, and immunoprecipitation. Serum and fecal IPA levels in high-fat diet-fed mice were significantly decreased compared with those of normal chow diet-fed mice. IPA supplementation reduced hepatic lipid accumulation and alleviated insulin resistance, liver damage, and steatosis development in high-fat diet-fed mice, while gut microbiota dysbiosis was restored. Mechanistic analysis suggested that IPA promoted FMO2 expression, enhancing the interaction between FMO2 and protein kinase R-like endoplasmic reticulum kinase (PERK) and inhibiting the PERK/eIF2α/ATF4/CHOP signaling cascade, then mitigating endoplasmic reticulum (ER) stress, such as reducing hepatocyte apoptosis and reactive oxygen species levels, ultimately improving MASLD. IPA can promote the expression of FMO2, which binds to PERK within the ER of hepatocytes. This binding process inhibits the phosphorylation of PERK, thereby affecting PERK-mediated ER stress, and subsequently leading to a reduction in hepatocyte apoptosis and oxidation. This study puts forward the IPA/FMO2/PERK axis as a potential therapeutic target in ER stress for MASLD.","42276391":"ID: 42276391\nTitle: Huanglian wendan decoction attenuates hepatic inflammation and lipogenesis via inhibition of the NF-κB/HDAC1/SREBP-1c axis.\nAbstract: Metabolic dysfunction-associated steatohepatitis (MASH) is characterized by hepatic steatosis accompanied by persistent inflammation and early fibrotic remodeling. In traditional Chinese medicine, Huanglian Wendan Decoction (HLWDD) is prescribed for phlegm-heat and damp-heat syndromes affecting the gallbladder and stomach and is traditionally used to clear heat, dry dampness, and resolve phlegm. It is commonly applied in the treatment of phlegm-heat-related metabolic disorders, including fatty liver disease. However, the therapeutic effects of HLWDD and the contributions of its key constituents to MASH remain to be further elucidated. This study aimed to evaluate the anti-inflammatory and lipid-regulatory effects of HLWDD and its key components in MASH and to explore the underlying molecular mechanisms. Male C57BL/6 J mice were given a methionine-choline-deficient (MCD) diet and received HLWDD in either low or high doses through oral gavage, with fenofibrate serving as a positive control. Body weight, liver index, serum levels of alanine aminotransferase and aspartate aminotransferase, serum lipid profiles, and hepatic triglyceride and total cholesterol contents were among the evaluated parameters. H&E, Oil Red O, and Masson's trichrome staining were used to evaluate histopathological changes. Hepatic macrophage infiltration was examined by immunofluorescence, inflammatory cytokines were measured by ELISA, and key signaling and lipid metabolism-related proteins were analyzed by western blotting. UPLC‒MS/MS was used to characterize the chemical profile of the HLWDD granules and identify their major constituents. Network pharmacology analysis integrating multiple databases, together with GO and KEGG enrichment analyses, was performed to predict potential targets and pathways. Molecular docking and molecular dynamics simulations were further used to investigate compound‒target interactions. Cell viability in vitro was measured with CCK-8 assays, protein levels were confirmed through western blotting, and intracellular lipid buildup was assessed using Oil Red O staining. UPLC‒MS/MS analysis revealed that berberine (BBR), an isoquinoline alkaloid, is a major bioactive component of HLWDD. Network pharmacology analysis suggested that HLWDD and BBR may exert anti-MASH effects by modulating multiple targets and pathways, including IL-6, PPARα, and the NF-κB/HDAC1/SREBP-1c axis. These predictions were supported by in vivo experiments, which confirmed the protective effects of HLWDD against MASH. Both in vivo and in vitro studies further revealed that BBR markedly ameliorated MASH-related phenotypes by suppressing the NF-κB/HDAC1/SREBP-1c axis. Additionally, simulations of molecular docking and dynamics revealed stable interactions between BBR and important proteins within this axis. Microscale thermophoresis (MST) assays further demonstrated direct binding of BBR to HDAC1. Collectively, these findings suggest that HLWDD and its key active constituent BBR alleviate MASH, at least in part, by inhibiting the NF-κB/HDAC1/SREBP-1c axis, which is closely associated with inflammatory responses and dysregulated lipogenesis. HLWDD markedly ameliorated the MASH phenotype by attenuating hepatic inflammation and lipogenesis, with the NF-κB/HDAC1/SREBP-1c axis emerging as a key mechanism linking inflammatory signaling to aberrant lipid synthesis. BBR, identified by UPLC‒MS/MS as a major active constituent of HLWDD, largely recapitulated these effects and directly bound to HDAC1, supporting its important contribution to the protective effects of HLWDD against MASH.","42277386":"ID: 42277386\nTitle: Modulating the Gut-Liver Axis: Anti-Inflammatory Mechanisms of Probiotics and Prebiotics in MASLD.\nAbstract: Non-alcoholic fatty liver disease (NAFLD), recently reclassified as metabolic dysfunction-associated steatotic liver disease (MASLD), is a prevalent metabolic disorder with significant inflammatory underpinnings. Emerging evidence underscores the gut-liver axis as a pivotal pathway in MASLD pathogenesis through which dysbiosis drives cytokine-mediated inflammation, fibrosis, and disease progression. This review synthesizes preclinical and clinical findings on how probiotics and prebiotics modulate key inflammatory cytokines-including TNF-α, IL-6, IL-1β, IL-10, IL-17, and TGF-β-to ameliorate MASLD. The literature demonstrates that these interventions converge on the TLR4/NF-κB axis as the central mechanistic driver of cytokine dysregulation in MASLD. By restoring gut barrier integrity and reducing endotoxin (LPS) translocation, probiotics and prebiotics suppress TLR4/NF-κB activation, which secondarily inhibits the NLRP3 inflammasome (reducing IL-1β/IL-18), downregulates pro-inflammatory cytokines (TNF-α, IL-6, IL-17), and enhances anti-inflammatory signals (IL-10) through crosstalk with PPAR-α, AMPK, and Nrf2 pathways. In animal models, probiotic strains such as Bifidobacterium, Lactobacillus, and Akkermansia muciniphila consistently downregulate pro-inflammatory cytokines and enhance anti-inflammatory signals. The same is true for prebiotics, including inulin, oat β-glucan, and synbiotic formulations. However, clinical trial outcomes remain heterogeneous, influenced by strain specificity, intervention duration, and patient heterogeneity. Collectively, this review highlights the therapeutic potential of microbiota-targeted interventions to rebalance cytokine networks and proposes future directions for personalized, mechanism-driven approaches to the management of MASLD.","42278231":"ID: 42278231\nTitle: Cyanidin-3-O-Glucoside Alleviates Hepatic Steatosis and Inflammation in High-Fat Diet-Induced Non-Alcoholic Fatty Liver Disease Mice via the AMPK/SIRT1/NF-κB Pathway.\nAbstract: Cyanidin-3-O-Glucoside (C3G) is the primary anthocyanin-active component in bilberry, exhibiting various pharmacological activities such as antioxidant, anti-inflammatory, and lipid metabolism-regulating effects. To address the clinical need for non-alcoholic fatty liver disease (NAFLD) prevention and treatment, this study aimed to investigate the ameliorative effects of C3G on NAFLD pathology and elucidate its molecular mechanisms of protection via the AMPK pathway. After a one-week acclimatization period, 20 six-week-old SPF mice were randomly divided into four groups: normal diet control (NCD), high-fat diet model (HFD), HFD + L-C3G (100 mg/kg/day), and HFD + H-C3G (200 mg/kg/day). Except for the NCD group, the remaining groups were fed a 60% high-fat diet for four weeks to establish an early-stage NAFLD model, with successful model construction verified by weight and liver weight gain. From the fifth week onward, C3G groups received daily administration for four consecutive weeks, while control groups were given an equal volume of distilled water. Liver function, lipid metabolism, oxidative stress, and inflammatory levels were assessed using ELISA, H&E staining, and other methods. The results showed that C3G restored liver function in NAFLD mice, improved lipid metabolism disorders, reduced oxidative stress and inflammatory responses, and alleviated liver pathological damage. Mechanistic studies revealed that C3G regulated the expression of mRNA and proteins related to the AMPK/SIRT1/NF-κB signaling pathway, activating the pathway by upregulating AMPK and its upstream regulators while inhibiting NF-κB-mediated inflammatory responses. This study confirmed that C3G can ameliorate high-fat diet-induced NAFLD lesions by activating the AMPK/SIRT1/NF-κB pathway, providing a potential intervention strategy for NAFLD prevention and treatment.","42278341":"ID: 42278341\nTitle: Aspirin Eugenol Ester Ameliorates Fatty Liver Hemorrhagic Syndrome in Laying Hens by Reducing Oxidative Stress and Inflammation.\nAbstract: Fatty liver hemorrhagic syndrome (FLHS) is a common metabolic disorder in laying hens, leading to reduced egg production and economic losses. Aspirin eugenol ester (AEE) has lipid-lowering, anti-inflammatory, and antioxidant properties, but its effects on FLHS are unknown. This study evaluated the protective effects of AEE using an in vivo FLHS model induced by a high-energy low-protein diet in laying hens and an in vitro steatosis model established by free fatty acid treatment in LMH cells. AEE alleviated liver histopathological damage, reduced oxidative stress (decreased ROS and MDA; increased SOD, GSH, and CAT), and suppressed inflammatory responses. The hepatoprotective effects of AEE were tentatively associated with altered molecular expression of the Nrf2 antioxidant pathway and MAPK/NF-κB inflammatory signaling; however, this correlation was speculated based on molecular detection and incomplete in vitro pharmacological interventions, lacking rigorous causal validation. These findings suggest that AEE alleviates FLHS-related liver injury in laying hens, possibly in association with altered oxidative and inflammatory status. Collectively, these preliminary findings provide a limited theoretical reference for the potential application of AEE as a preventive agent against FLHS in laying hens.","42280144":"ID: 42280144\nTitle: Natural Bioactive Compounds Targeting Gut Barrier Integrity and Metabolic Endotoxemia in Cardiometabolic Disease: Mechanistic Insights and Translational Perspectives.\nAbstract: Cardiometabolic diseases are increasingly recognized as disorders of chronic low-grade systemic inflammation and gut barrier dysfunction that mutually reinforce one another. Each condition amplifies the other through progressive injury to the intestinal epithelium. Compromise of the mucus layer, altered tight junction dynamics, dysbiosis, and impaired epithelial restitution promote intestinal permeability and enable the translocation of lipopolysaccharide and other microbial products into the circulation, thereby inducing metabolic endotoxemia. This gut derived inflammatory signal activates Toll like receptor 4, nuclear factor kappa B, and inflammasome associated pathways, linking barrier dysfunction to insulin resistance, hepatic steatosis, adipose tissue inflammation, endothelial activation, and vascular injury. Here, we examine the gut barrier as an immunometabolic interface and synthesize current evidence connecting its disruption to endotoxin driven cardiometabolic pathology. We further evaluate selected natural bioactive compounds, including curcumin, resveratrol, quercetin, epigallocatechin gallate, berberine, anthocyanins, omega 3 polyunsaturated fatty acids, and dietary polysaccharides, as gut targeted interventions capable of reinforcing junctional integrity, restoring mucus and microbial homeostasis, lowering endotoxin burden, and attenuating inflammatory signaling. Finally, we highlight the principal translational barriers that currently limit clinical implementation, including pharmacokinetic variability, microbiota dependent biotransformation, source standardization, and the lack of robust, standardized biomarkers of barrier restoration and metabolic endotoxemia.","42280311":"ID: 42280311\nTitle: Insulin-like Growth Factor 1 Ameliorates Intestinal Barrier Dysfunction in MASLD via IGF-1R/PI3K/AKT Signaling.\nAbstract: Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) represents a globally prevalent hepatic disorder, characterized by hepatic lipid accumulation and extrahepatic complications, notably intestinal barrier injury, which further exacerbates MASLD progression. The \"gut-liver axis\" has been identified as a critical contributor to MASLD development, with insulin-like growth factor 1 (IGF-1) serving as a pivotal coupling factor of this axis. However, the specific role and molecular mechanism by which IGF-1 modulates intestinal barrier function in the context of MASLD remains unclear. Methods: This study analyzed the correlations between the GH/IGF-1 axis and intestinal barrier function in MASLD rats, and explored the effects of IGF-1 intervention both in vivo and in vitro. Results: Our results showed that MASLD rats exhibited intestinal barrier impairment, characterized by elevated serum Diamine oxidase (DAO) and D-Lactate (D-LAC) levels, villus damage, and downregulation of tight junction proteins and Mucin (MUC2). These changes were accompanied by suppression of the GH/IGF-1 axis. Correlation analysis uncovered a negative association between IGF-1 levels and markers of barrier dysfunction. IGF-1 intervention effectively repaired the intestinal barrier structure of MASLD rats and significantly upregulated the expressions of IGF-1R, PI3K, and AKT. In vitro, IGF-1 treatment improved transepithelial electrical resistance (TEER), enhanced barrier-related gene expression, promoted cell proliferation, and inhibited apoptosis. Conclusions: These findings suggested that GH/IGF-1 axis suppression, intestinal barrier dysfunction, and IGF-1R/PI3K/AKT signaling were interconnected within the gut-liver axis in MASLD. IGF-1 may contribute to barrier regulation through associated signaling changes, highlighting the GH/IGF-1 axis as a potential complementary target.","42290032":"ID: 42290032\nTitle: Optimization of Deep Eutectic Solvent Extraction Process and Study on the Anti-Alcoholic Fatty Liver Disease Activity and Mechanism of Flavonoids From Lophatherum gracile Brongn.\nAbstract: Deep eutectic solvents (DESs) are a novel type of green extraction medium characterized by strong designability, biodegradability, and high extraction efficiency, making them highly promising for the separation of bioactive components from natural products. Lophatherum gracile Brongn. (L. gracile) is rich in various bioactive components, including flavonoids and polysaccharides. This study established a DES-based extraction system for flavonoids of L. gracile, optimized the process using response surface methodology, and evaluated the antioxidant activity, and hepatoprotective effects of the extracts against alcoholic liver disease (ALD) with focus on gut microbiota modulation. A choline chloride-malic acid DES was identified as the optimal extractant. Under the optimized conditions (extraction time of 60 min, water content of 32%, liquid-to-solid ratio of 61:1 mL/g, molar ratio of 1:1, ultrasonic power of 480 W, and temperature of 60°C), the extraction yield of L. gracile flavonoids reached 16.62 ± 0.27 mg/g. Compared to traditional ethanol extracts, the DES-extracted L. gracile flavonoids exhibited significantly stronger DPPH radical scavenging activity. Moreover, they demonstrated enhanced hepatoprotective effects in an ALD mouse model by ameliorating dyslipidemia, alleviating liver injury, and improving hepatic histopathology. Notably, the DES extracts more effectively reshaped the alcohol-disrupted gut microbiota by increasing beneficial bacteria (e.g., Akkermansia and Lactobacillus) while suppressing pathogenic genera (e.g., Escherichia-Shigella and Bacteroides). These findings provide an efficient and environmentally friendly extraction strategy for L. gracile flavonoids and offer experimental evidence for their potential application in alcoholic liver disease prevention and treatment through gut microbiota modulation.","42290500":"ID: 42290500\nTitle: Probiotic, synbiotic effects on the gut-liver axis: omics-enabled mechanisms and therapeutic windows.\nAbstract: The gut-liver axis is a two-way communication network where gut microbes and their metabolites affect liver function, while the liver regulates the intestinal environment through bile acids, immune factors, and antimicrobial substances. Disruption of this balance contributes to various liver diseases, including nonalcoholic fatty liver disease, alcohol-associated liver disease, cirrhosis, and liver cancer. Probiotics and synbiotics are potential therapies that aim to restore microbial balance, strengthen the intestinal barrier, and regulate inflammation and metabolism. Recent omics technologies, such as metagenomics, metabolomics, transcriptomics, and proteomics, have helped uncover how these interventions influence important pathways involving short-chain fatty acids, bile acids, and microbial metabolites. Studies suggest that probiotics and synbiotics may improve liver health through effects on metabolism, immune regulation, and fibrosis, although results vary depending on the specific microbial strains and patient characteristics. Emerging approaches include next-generation probiotics, targeted synbiotic combinations, and personalized microbiome-based treatments. Combining multi-omics data with digital health tools may help identify patients who are most likely to benefit. Overall, microbiota-targeted therapies show promise as personalized strategies for managing liver diseases, but further research is needed to overcome challenges in translating findings into consistent clinical applications.","42290856":"ID: 42290856\nTitle: Quantifying the metabolic-inflammatory axis: synergistic value of TyG index and FAI in assessing CAD risk among MAFLD patients.\nAbstract: This study evaluated coronary inflammation and insulin resistance (IR) using pericoronary fat attenuation index (FAI) and triglyceride-glucose (TyG) index, and assessed their associations with coronary heart disease (CHD) and functional ischemia in patients with metabolic dysfunction-associated fatty liver disease (MAFLD). A total of 435 patients (174 MAFLD, 261 MAFLD+CHD) were included. The MAFLD+CHD group was stratified by CT-derived fractional flow reserve (CT-FFR) into >0.80 and ≤0.80 subgroups. FAI and CT-FFR were automatically calculated using AI-based software; Independent risk factors were identified using multivariable logistic regression analysis, based on which a nomogram was constructed. The predictive performance of the nomogram was evaluated using ROC curves, calibration curves, and decision curve analysis (DCA), with internal validation performed via the Bootstrap method. The predictive accuracy of the nomogram was also compared with that of FAI and the TyG index. Restricted cubic spline (RCS) models were employed to explore the potential nonlinear relationship between the TyG index and FAI, as well as the dose-response associations of these indices with disease risk. Multivariate logistic regression showed that TyG index and FAI were independent risk factors for CHD and coronary functional ischemia (P<0.05), with CHD prevalence, functional ischemia, and TyG levels increasing alongside FAI. In MAFLD patients, the nomogram demonstrated excellent discrimination (ROC-AUC 0.952, 95% CI 0.935-0.970), and DCA, clinical net reduction, and clinical impact analyses confirmed its substantial clinical value in identifying high-risk CHD patients. For MAFLD patients with CHD, the nomogram also effectively predicted coronary functional ischemia (AUC 0.904, 95% CI 0.869-0.939). While FAI and TyG, alone or combined, had predictive value, the nomogram outperformed all single and combined indicators (AUCs 0.952 and 0.904; P<0.001). RCS analysis revealed a linear positive correlation be-tween TyG and FAI, both positively associated with CHD and functional ischemia risk. In patients with MAFLD and those with concomitant CHD, FAI was significantly positively correlated with the TyG index, and both were associated with the occurrence of CHD and coronary functional ischemia, suggesting that systemic metabolic dysfunction may promote disease progression through local coronary inflammation. Furthermore, a nomogram integrating the TyG index, FAI, and key clinical variables demonstrated excellent discriminative ability in internal validation, providing incremental diagnostic value for early CHD risk stratification in MAFLD patients.","42294883":"ID: 42294883\nTitle: Astragalus polysaccharides ameliorate perinatal metabolic syndrome in sows via enhancing butyrate-producing bacteria.\nAbstract: Astragalus polysaccharide (APS), a bioactive phytomacromolecule from Astragalus membranaceus, exhibits anti-inflammatory, antioxidant, and immunomodulatory activities. Given mammals' lack of endogenous glycosidases for APS catabolism, this study hypothesizes its bioactivity stems from gut microbial interactions, investigating APS-mediated microbiome remodeling and therapeutic effects on perinatal metabolic syndrome (PeriMS) in sows. In vitro fermentation showed that APS significantly increased short-chain fatty acid (SCFA) production, with acetate (44.51 mmol/L), propionate (17.37 mmol/L), and butyrate (22.04 mmol/L) levels notably elevated and enriched canonical butyrate-producing taxa (g_norank_f_Muribaculaceae, g_Monoglobus, g_unclassified_f_Lachnospiraceae, P < 0.05). In vivo, gestational APS supplementation (from day 90) improved piglet weaning weight, reduced maternal backfat loss during lactation, shortened post-weaning estrus interval, elevated intestinal butyrate, alleviated systemic inflammation/oxidative stress, and mitigated PeriMS. Mechanistic analysis associated PeriMS improvement with butyrate-producing bacteria, with butyrate playing a key role in gut health enhancement. These findings establish APS as a prebiotic, highlighting the gut microbiota-SCFA axis as a therapeutic target for PeriMS. This study provides targeted mechanistic evidence that the gut microbiota-SCFA axis mediates PeriMS improvement by APS. Mechanistic analysis linked PeriMS improvement to butyrate-producing bacteria, with butyrate playing a key role in gut health enhancement, which was verified by a sodium butyrate rescue experiment. These findings establish APS as a prebiotic, highlighting the gut microbiota-SCFA axis as a therapeutic target for PeriMS. This work provides novel evidence for microbiota-SCFA axis involvement in sow perinatal metabolic health, offering translational strategies to improve livestock metabolic health through APS supplementation. In intensive pig farming, 40% of multiparous sows develop perinatal metabolic syndrome (PeriMS) around farrowing, causing $150-$200 annual loss per sow due to inflammation (e.g., higher IL-6), oxidative stress, and extended weaning-to-estrus intervals (2.1 days). Gut dysfunction-marked by fewer butyrate-producing bacteria and increased endotoxin-triggers barrier damage and inflammation. Supplementing with Astragalus polysaccharides (APS, 10 g/day) enhances beneficial bacteria like Muribaculaceae and butyrogenic Bacteroides, raising butyrate in vitro. In sows, APS lowers endotoxemia and gut inflammation (calprotectin), correlating with reduced postpartum IL-6 and reactive oxygen species. It also improves productivity: less backfat loss and heavier weaned piglets. By targeting gut-barrier crosstalk, APS breaks the inflammation-metabolism cycle, providing a sustainable alternative to antibiotics to enhance peripartum sow health and profitability.","42296782":"ID: 42296782\nTitle: Macrophage plasticity as a therapeutic target in inflammatory bowel disease: Immunomodulatory and regenerative strategies.\nAbstract: Inflammatory bowel disease (IBD), which mainly includes Crohn's disease and ulcerative colitis, is a chronic inflammatory disorder of the gastrointestinal tract characterized by recurrent episodes of intestinal inflammation. The development of IBD is influenced by multiple factors, including genetic predisposition, intestinal dysbiosis, epithelial barrier impairment, and abnormal immune activation. Among innate immune cells, macrophages are key regulators of intestinal immune homeostasis and are involved in inflammatory responses, tissue remodeling, and mucosal repair. Their ability to adopt different functional states in response to local environmental signals has made them an important focus of current therapeutic research in IBD. Traditionally, macrophages have been classified into pro-inflammatory M1 and anti-inflammatory M2 phenotypes. However, recent findings from single-cell transcriptomic and spatial analyses suggest that intestinal macrophages represent a far more diverse and dynamic population than this simplified classification implies. Multiple macrophage subsets with inflammatory, regulatory, reparative, and fibrosis-associated functions coexist within the intestinal microenvironment and contribute differently to disease progression and tissue healing. These observations highlight the importance of developing more selective and targeted macrophage-based therapeutic approaches. In this review, we discuss the current understanding of macrophage plasticity and its role in the pathogenesis of IBD. Particular attention is given to newer macrophage-targeted therapeutic strategies, including adoptive macrophage transfer, engineered macrophages, receptor-targeted therapies, nanoparticle-based delivery systems, microbiome modulation, microbial metabolite regulation, gene-editing approaches, organoid technologies, and biomaterial-assisted platforms. We also examine the contribution of macrophages to epithelial regeneration, mucosal healing, fibrosis, and intestinal tissue remodeling. In addition, we address several major challenges that currently limit the clinical translation of macrophage-targeted therapies. A better understanding of macrophage biology, together with continued advances in immunology, regenerative medicine, microbiome research, and biomaterials science, may support the development of more precise and personalized therapeutic strategies for patients with IBD.","42298689":"ID: 42298689\nTitle: Dachaihu decoction alleviates septic liver injury by modulating the intestinal barrier dysfunction and suppressing the NF-κB/NLRP3/Caspase-1 signaling pathway.\nAbstract: Intestinal barrier dysfunction is a key driver of septic liver injury (SLI). Dachaihu decoction (DCHD), a classic traditional Chinese medicine formula recorded in the Treatise on Cold Damage, is widely used to treat gastrointestinal and hepatic inflammatory conditions. The primary objective of our research was to elucidate the protective effects of DCHD against SLI and the underlying molecular mechanisms. In a murine model of sepsis induced by cecal ligation and puncture (CLP), we evaluated the therapeutic effects of DCHD on SLI by assessing serum liver enzymes, histopathology, oxidative stress, hepatocyte apoptosis, and inflammatory cytokines. Intestinal barrier integrity was examined via transmission electron microscopy, serum biomarkers (D-lactate, DAO, LPS), and tight junction proteins (ZO-1, Occludin, E-cadherin). Gut microbiota composition was analyzed using 16S rRNA sequencing. Chemical profiling of DCHD was performed via UPLC-Q-TOF-MS. Integrated network pharmacology, bioinformatics, and transcriptomic analyses identified the NF-κB/NLRP3/Caspase-1 axis as a potential mechanism, which was validated in vivo and in LPS-stimulated immortalized mouse Kupffer cells (ImKCs). Functional involvement of TLR4 and NLRP3 was further confirmed by genetic silencing of TLR4 with siRNA and pharmacological inhibition using TAK-242 (TLR4 inhibitor) and MCC950 (NLRP3 inhibitor). DCHD treatment attenuated liver injury in CLP-induced septic mice, as evidenced by improved liver function, attenuated histopathology, reduced oxidative stress, suppressed inflammation, and decreased hepatocyte apoptosis. These hepatoprotective effects were associated with reduced intestinal permeability and enhanced barrier integrity, alongside gut microbiota remodeling characterized by enrichment of beneficial bacteria and reduced abundance of gram-negative genera (e.g., Klebsiella, Enterobacter, Proteus), leading to decreased LPS production and translocation to the liver. Integrated network pharmacology and transcriptomics revealed the NF-κB/NLRP3/Caspase-1 axis as a central mechanism, with DCHD downregulating p-p65, p-IκBα, NLRP3, ASC, and Cleaved Caspase-1 in vivo and in LPS-stimulated ImKCs. Functional validation using TLR4 siRNA and the inhibitors TAK-242 and MCC950 confirmed that DCHD might attenuate liver inflammatory injury primarily through the NF-κB/NLRP3/Caspase-1 signaling pathway. DCHD may alleviate SLI by enhancing the intestinal barrier, potentially reducing the translocation of gut-derived LPS to the liver, and subsequently inhibiting the NF-κB/NLRP3/Caspase-1 axis, highlighting its considerable translational potential for SLI therapy.","42299366":"ID: 42299366\nTitle: Hepatogenomics of MAFLD in Asian Population: Genetic Polymorphisms and Pathway-Based Insights.\nAbstract: Metabolic dysfunction-associated fatty liver disease (MAFLD) has emerged as a major public health concern across Asia, marked by rising prevalence, younger age at presentation, and variability in clinical course. This variability reflects a complex interplay between metabolic exposures and genetic architecture, contributing to heterogeneity in disease susceptibility and progression. While dietary patterns, sedentary lifestyle, and metabolic comorbidities remain central contributors, inherited susceptibility influences hepatic fat accumulation, progression to steatohepatitis, and fibrotic transformation. This review aims to summarize genetic polymorphisms implicated in MAFLD among Asian populations and to explore their role in identifying individuals at increased inherited risk. A pathway-oriented perspective is adopted to contextualize how these variants contribute to key biological mechanisms underlying MAFLD. A narrative review approach was employed, drawing upon genome-wide association studies, candidate gene analyses, and functional research. Genetic variants were grouped into principal pathogenic pathways, including lipid handling, insulin resistance and de novo lipogenesis, cholesterol metabolism, inflammatory signaling, and fibrogenesis. While emphasis is placed on evidence from Asian cohorts, selected variants are also discussed based on mechanistic relevance, even when direct population-based data remain limited. Differences in allele frequency and effect size between Asian and Western populations were considered to clarify ethnic variation. Among the identified variants, PNPLA3 rs738409 consistently emerges as a dominant determinant of hepatic fat accumulation and adverse histological features. Additional polymorphisms further modulate risk, with some exerting protective effects. Taken together, current evidence supports integrating genetic markers into risk stratification models for earlier recognition of genetically predisposed individuals. This pathway-based synthesis provides a framework for understanding MAFLD heterogeneity in Asian populations and may inform precision-oriented prevention and individualized management.","42300918":"ID: 42300918\nTitle: The hawthorn (Crataegus pinnatifida) procyanidin extract attenuates nonalcoholic fatty liver disease in mice via remodeling the bile acid profile driven by gut microbiota and regulating the FXR pathway.\nAbstract: Hawthorn procyanidin extract (HPC) is one of natural plant-derived polyphenols with lipid-lowering and liver-protective properties, while its therapeutic mechanisms against nonalcoholic fatty liver disease (NAFLD) require further clarification. A high-fat diet (HFD)-induced NAFLD mouse model and oleic acid (OA)-induced HepG2 cells were utilized to conduct this study. We first found that HPC intervention ameliorated lipid accumulation in HepG2 cells, which was confirmed to depend on FXR signaling using an FXR inhibitior. In addition, HPC significantly relieved NAFLD in vivo by lowering the levels of TC, TG, and LDL-C and preventing the excessive accumulation of lipid droplets and hepatic steatosis. Besides, HPC intervention restored BA homeostasis (in the liver and gut) by markedly altering the profiles of primary versus secondary and conjugated versus unconjugated BAs (ωMCA, TαMCA, TβMCA, and DCA), which was related to the restoration of the HFD-induced dysbiosis. Mechanistically, HPC downregulated the expression of lipid synthesis protein SREBP1 by activating the hepatic FXR and CYP7A1 expressions, attributed to the controlling of the enterohepatic circulation mediated by the FXR-FGF15 pathway. Taken together, these findings substantiate that HPC exerts its ameliorative effect on NAFLD by modulating BA metabolism in NAFLD mice.","42304914":"ID: 42304914\nTitle: Guar Gum, Partially Hydrolyzed Guar Gum, and Human Gut Health: A Narrative Review.\nAbstract: Dietary fibers, and more specifically water-soluble fibers, beneficially affect human health. Guar gum and its enzymatic product, partially hydrolyzed guar gum (PHGG), are among the most studied dietary fibers in humans. Altogether, they can be described as \"guar fiber\". We performed a narrative review of the literature on guar fiber, namely guar gum and its partially hydrolyzed product, and their impact on human health, with a special focus on the gastrointestinal tract, gut microbiota, gut-brain axis, and liver steatosis. Accordingly, a literature search was conducted using the following keywords and combinations: guar fiber, guar gum, partially hydrolyzed guar gum, disorders of gut-brain interaction, gut-liver axis, and gut microbiota. Guar gum and its derivative, PHGG, show promising effects in gastrointestinal disorders, such as constipation and diarrhea. Interestingly, they can modulate the gut microbiota, with promising implications for the gut-brain axis and disorders of gut-brain interaction, such as irritable bowel syndrome. There are also interesting, albeit preliminary, results regarding their use in fatty liver disease. Thus, dietary fibers such as guar gum and, more importantly, its hydrolyzed product, show promising and better-documented effects on the health of the gastrointestinal tract and other organs and systems of the human body. However, the latter evidence still requires clinical confirmation of preclinical findings. Overall, the reviewed data vary in quality and maturity across different outcome domains.","42307179":"ID: 42307179\nTitle: The evolving therapeutic landscape of gut-pancreatic peptide signalling in metabolic disorders: from mono- to multi-agonist therapies.\nAbstract: The pharmacotherapeutic landscape for the clinical management of type-2 diabetes (T2D), obesity, metabolic dysfunction-associated steatotic liver disease (MASLD), and steatohepatitis (MASH) is evolving swiftly in response to the escalating global prevalence and incidence of these interrelated metabolic disorders. Although insulin and metformin formulations have long constituted the foundation of diabetes care, a paradigm shift in T2D management has been observed with the advent of novel pharmacotherapies. Gut peptide analogues are at the forefront of this transformation. The emergence of glucagon-like peptide-1 (GLP-1) receptor agonists represents a watershed moment, fundamentally reshaping the therapeutic landscape for both T2D and obesity due to multifaceted metabolic benefits. The clinical success of GLP-1-based therapies has stimulated pharmaceutical interest in other metabolic peptides. Gut-pancreatic peptides such as glucose-dependent insulinotropic polypeptide (GIP), glucagon, amylin, and peptide YY (PYY) are of particular interest due to their distinct pharmacological benefits and therapeutic promise in metabolic disorders. This review aims to provide a comprehensive and current overview of non-insulin gut-pancreatic peptide signalling-based therapies that are either clinically approved or under clinical investigation, with a focus on the emerging therapeutic convergence between T2D, obesity and associated liver disease. The review critically narrates their mechanisms of action, therapeutic efficacy, limitations, current development status, and positioning in the treatment landscape. Furthermore, the review delineates the emerging avenues in the development of novel peptide-based pharmacotherapies, offering insights into their future potential and acquainting the reader with developments in non-insulin gut-pancreatic peptide signalling-based therapies for metabolic disorders.","42310179":"ID: 42310179\nTitle: CD59 drives diet-induced obesity and glucose intolerance, insulin resistance, and metabolic dysfunction-associated steatotic liver disease.\nAbstract: CD59 is known as a membrane-bound regulator of the complement system that prevents the formation of the membrane attack complex on host cells. Here we report the metabolic consequences of CD59a knockout (KO) in mice fed a high-fat diet (HFD). Mice lacking CD59a were protected from the development of insulin resistance, glucose intolerance, hyperinsulinemia, obesity, and fatty liver. Mutants fed an HFD had elevated adiponectin levels and reduced leptin levels in plasma. Data from metabolic cages suggested decreased appetite and an increase in voluntary wheel activity in mutants. Liver transcriptome analysis showed a marked decrease of inflammatory and fibrotic pathways in CD59a KO mice on an HFD, and plasma and liver metabolomics were remarkably similar, indicating close correspondence between systemic and hepatic metabolic profiles. In conclusion, we uncover a noncanonical role of CD59a in the development of diet-induced insulin resistance, hyperinsulinemia, glucose intolerance, and obesity.","42310552":"ID: 42310552\nTitle: Integrative multi-omics analysis reveals a gut-liver axis signature of metabolic reprogramming associated with response to transarterial chemoembolization in hepatocellular carcinoma.\nAbstract: Transarterial chemoembolization (TACE) is a standard treatment for intermediate-stage hepatocellular carcinoma (HCC), but response is highly variable. The systemic metabolic impact of TACE and its connection to tumor-intrinsic factors governing efficacy remain poorly understood. We hypothesized that by comparing host fecal metabolomics with tumor transcriptomics, we could identify convergent pathways suggestive of a gut-liver axis signature of TACE response. We performed untargeted fecal metabolomics in a prospective paired cohort of 30 HCC patients sampled before TACE and again on post-TACE day 4, an early time point selected to capture acute ischemic, inflammatory, and metabolic perturbations after embolization. To characterize tumor-intrinsic programs associated with efficacy, we analyzed the independent public transcriptomic dataset GSE104580 containing pre-treatment tumors from TACE responders and non-responders. Cross-cohort integration was conducted at the pathway level to identify convergent biological themes. For metabolomics, paired univariate testing with Benjamini-Hochberg false discovery rate (FDR) correction and Variable Importance in Projection (VIP) > 1 from PLS-DA were used; for transcriptomics, differential expression used adjusted p < 0.05 and |log2FC|> 1, followed by GSEA. TACE induced a shift in the fecal metabolome, with significant enrichment of glycerophospholipid metabolism, together with changes in bile acid-related metabolites and tryptophan/vitamin B6-related metabolites. Lysophosphatidylcholines (LysoPCs), including LysoPC (22:4), and bile acid-related metabolites were increased after TACE, consistent with acute treatment-associated tissue metabolic perturbation. Independent transcriptomic analysis revealed that responder tumors were enriched for primary bile acid biosynthesis, fatty acid degradation, and tryptophan metabolism, with higher expression of CYP7A1, ACOX1, IDO1, and TDO2, whereas non-responders were enriched for Cell cycle, DNA replication, and ribosome-related programs. Because the metabolomics and transcriptomics datasets were derived from separate cohorts, these convergent findings support a pathway-level cross-cohort model rather than direct patient-level tumor-fecal linkage. Our comparative analysis suggests a potential gut-liver axis signature associated with TACE efficacy. We therefore present fecal LysoPC as a candidate non-invasive pharmacodynamic readout of acute post-TACE tissue injury and host-microenvironmental perturbation rather than a tumor-necrosis-specific biomarker. Likewise, the convergence on bile acid and tryptophan metabolism suggests that a responder-associated tumor metabolic phenotype may be relevant to TACE sensitivity. These findings offer potential non-invasive biomarkers and highlight new therapeutic targets to enhance TACE efficacy.","42311944":"ID: 42311944\nTitle: Dendrobium officinale polysaccharide ameliorates high-fat diet-induced hepatic lipid metabolic disorder via the SIRT6/PGC-1α signaling axis.\nAbstract: This study aims to explore the potential therapeutic effect of Dendrobium officinale polysaccharide (DOP) on non-alcoholic fatty liver disease (NAFLD) induced by high-fat diet (HFD), and to elucidate the underlying mechanism involving the SIRT6/PGC-1α signaling axis and the regulation of the gut microbiota. We extracted and characterized DOP. We established a rat model of NAFLD induced by HFD and evaluated the efficacy of DOP by integrating multi-omics techniques (transcriptomics, metabolomics) and 16S rRNA sequencing. To verify the specific role of SIRT6, we introduced the SIRT6 inhibitor OSS_128167 in the primary hepatocyte model induced by oleic acid/palmitic acid (OA/PA). DOP significantly alleviated liver steatosis, oxidative stress, and lipid metabolism disorders induced by HFD. Multi-omics analysis indicated that DOP regulated liver glycerophospholipid metabolism and restored intestinal microbiota homeostasis, significantly increasing the abundance of beneficial bacteria such as Lactobacillus. Mechanistically, DOP activated the liver SIRT6/PGC-1α signaling axis, thereby enhancing antioxidant defense and inhibiting lipogenesis. Crucially, in vitro experiments confirmed that the SIRT6 inhibitor OSS_128167 eliminated the protective effect of DOP on lipid accumulation, confirming that the effect of DOP depends on SIRT6. DOP improves NAFLD through dual mechanisms of regulating the gut-liver axis homeostasis and directly activating the liver SIRT6/PGC-1α signaling pathway. The results of this study provide a theoretical basis for developing DOP as a drug for the treatment of NAFLD.","42315051":"ID: 42315051\nTitle: Microbial metabolites contribute to the pathogenesis of metabolic dysfunction-associated fatty liver disease in high-fat diet-fed mice.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) affects approximately one-third of the global population and is a leading cause of chronic liver disease. Understanding the underlying metabolic pathways offers valuable insights into disease progression and potential therapeutic approaches. Dysregulation of the gut-liver axis and microbial imbalance contribute to MASLD progression by compromising intestinal barrier integrity, altering microbe-mediated metabolites, and promoting chronic hepatic inflammation. However, the specific metabolic disruptions in MASLD and the mechanisms through which microbes and their metabolites influence liver injury remain poorly understood. Six-week-old C57BL/6J mice were randomly assigned to five groups: baseline, normal chow (NC)_8w, NC_16w, MASLD_8w, and MASLD_16w. Mice in the MASLD groups were fed a high-fat diet (HFD), while the control groups were fed an NC diet. Body weight, liver function, and histopathological changes were evaluated, along with hepatic metabolomic profiling and fecal 16S ribosomal RNA gene sequencing. HFD-fed MASLD mice exhibited significant liver dysfunction, hepatic lipid accumulation, and increased body weight, triglycerides (TG), and cholesterol (CHO). Metabolomic analysis revealed marked disruption of hepatic metabolic homeostasis, particularly in lipid metabolism. Arachidonic acid metabolism was significantly altered and accompanied by increased levels of inflammatory mediators, including arachidonic acid (AA) and prostaglandin E2. In parallel, the relative abundance of Enterobacteriaceae was elevated in MASLD mice and showed a significant positive correlation with the hepatic accumulation of phosphatidylcholine (PC) (18:4(6Z,9Z,12Z,15Z)/16:1(9Z)), a phosphatidylcholine species annotated as a potential precursor of arachidonic acid. This coordinated alteration in gut microbial composition and hepatic lipid metabolites was associated with hepatic inflammatory responses in MASLD. Our findings demonstrate that hepatic inflammatory activation in MASLD is closely associated with reprogramming of the AA metabolic pathway. The observed Enterobacteriaceae-PC-AA correlation provides a potential mechanistic explanation for gut-liver crosstalk in MASLD progression, and may serve as a promising non-invasive biomarker candidate and therapeutic target for further functional validation.","42318107":"ID: 42318107\nTitle: Effect of Oral and Gut Microbiota, Dietary Intake, and Genetic Polymorphisms on Older Adults with Metabolic Dysfunction Associated Fatty Liver Disease.\nAbstract: This study aimed to investigate the factors involved in the development and progression of metabolic dysfunction-associated fatty liver disease (MASLD) in older adults from various aspects. Among general residents aged ≥60 years who participated in a health checkup project, 124 individuals in a normal group and 77 in an MASLD group were targeted in this study. Differences in nutrient intake, MASLD-related single nucleotide polymorphisms (SNPs), and oral and gut microbiota between the normal and MASLD groups were investigated. Furthermore, multivariate analysis was conducted to determine which cardiometabolic criteria were associated with the identified variables. The MASLD group had increased oral Veillonella and Megasphaera and decreased gut Blautia. Oral Veillonella and Magasphaera were positively associated with body mass index (BMI), waist circumference, and systolic blood pressure. Gut Blautia negatively correlated with BMI, waist circumference, fasting blood sugar, HbA1c, triglycerides, and positively correlated with high-density lipoprotein cholesterol. However, no association was observed between nutritional intake and SNPs. Because oral and gut microbiota are strongly involved in MASLD in older individuals, improving oral hygiene and probiotics may prevent the onset and progression of MASLD by improving the oral and gut environment.","42318205":"ID: 42318205\nTitle: Effects of SGLT-2 inhibitors and GLP-1 receptor agonists on liver function in patients with non-alcoholic fatty liver disease and type 2 diabetes.\nAbstract: The goal was having the comparisons be direct when it came to seeing how much of a help the sodium-glucose co transporter - 2 inhibitors (SGTL2is) compared to the glucagon-like peptide-1 receptor agonists (GLP-1RAs) were in regard to how the liver enzymes performed within people having type 2 diabetes (T2D) along with nonalcoholic fatty liver disease (NAFLD), a condition characterized by excessive fat accumulation in the liver without alcohol overconsumption. A total of 705 subjects with T2DM and NAFLD at time of first SGLT2is (n=381) or GLP-1RAs (n=324) enrolment in this multicentre posterior cohort study from 01/2020-12/2024. Baseline characteristics were made equivalent via PSM via a 1: 1 NN match and a 0. 2 SD match clamp. The main measurement was the difference in alanine amino transferase (ΔALT) and aspartate aminotransferase (ΔAST) from the beginning and 6 months. And other result was about the change in metabolic parametres. The independent predictors of liver-enzyme change came from the multivariate linear regression analysis. After PSM, 243 well-matched pairs were successfully identified, with baseline characteristics acceptably balanced (standardized differences <0.2 for all covariates and <0.1 for most covariates). In the matched cohort, SGLT2is treatment was associated with significantly greater reductions in ALT (ΔALT: -10.55 ± 12.66 vs. -7.28 ± 15.34 U/L, p=0.011) and AST (ΔAST: -7.68 ± 10.07 vs. -5.18 ± 11.04 U/L, p=0.010) compared to GLP-1RAs treatment. No significant differences were observed for changes in GGT, body weight, glycemic control, or lipid profiles between groups. Multivariable regression analysis revealed that SGLT2is treatment was independently associated with reductions in both ALT (β = -3.34, p=0.009) and AST (β = -2.32, p=0.016). Weight change was independently associated with AST reduction (β = 0.22, p=0.016) but not with ALT reduction. SGLT2is were associated with greater ALT and AST reductions than GLP-1RAs in T2D patients with NAFLD, with ALT improvement independent of weight loss, suggesting potential direct hepatoprotective effects.","42321612":"ID: 42321612\nTitle: Adherence to the dietary index for gut microbiota and the 5-year incidence of metabolic dysfunction-associated steatotic liver disease in Iranian adults: a prospective cohort study.\nAbstract: Diet is a key modulator of gut microbiota and may influence the development of metabolic dysfunction-associated steatotic liver disease (MASLD). The Dietary Index for Gut Microbiota (DI-GM) has been proposed to capture the overall capacity of diet to promote a favorable gut microbial profile. Prospective evidence linking DI-GM to MASLD risk remains limited. This prospective analysis included 5,058 adults without MASLD at baseline from the Monitoring of Metabolic Diseases Risk Factors in Tehran (MMRT) study. Dietary intake was assessed using a validated 125-item food frequency questionnaire. The five-year incidence of MASLD was evaluated using multivariable logistic regression models, and associations were expressed as odds ratios (ORs) with 95% confidence intervals (CIs). Subgroup analyses were conducted to assess potential effect modification. Sensitivity analyses examined the robustness of results after excluding participants with substantial weight gain and after additional adjustment for metabolic and dietary factors. Mediation analyses were performed to explore potential pathways underlying the observed associations. Over five years of follow-up, 562 participants developed MASLD. Higher DI-GM scores were associated with a lower likelihood of incident MASLD. In the fully adjusted model, individuals in the highest quartile of DI-GM had 42% lower odds of MASLD compared with those in the lowest quartile (OR:0.58; 95%CI:0.42-0.80; P-trend < 0.01). Each one-standard-deviation increment in DI-GM score was associated with reduced odds of MASLD (OR:0.72; 95%CI:0.65-0.81;P-value < 0.001). The inverse association was more pronounced among women and participants aged ≥ 45 years (P-interaction < 0.01). Mediation analyses suggested that CAP, HOMA-IR, and serum vitamin D partially explained the association. Greater adherence to a diet supportive of gut microbiota, as reflected by higher DI-GM scores, was associated with a lower five-year risk of MASLD. These findings highlight the potential role of microbiota-related dietary patterns in MASLD prevention.","42322285":"ID: 42322285\nTitle: Oxymatrine: Hepatoprotective Effects of a Multitarget Natural Alkaloid.\nAbstract: Liver diseases are a major global health burden with an occult onset and atypical symptoms, hindering early diagnosis.

Here, we evaluated the safety and metabolic effects of semaglutide, a GLP-1 receptor agonist (GLP-1 RA), administered from preconception through lactation in dams fed a high-fat diet (HFD) or standard diet, and assessed metabolic outcomes in dams and their offspring. Offspring were weaned to a standard diet. We found that semaglutide improved body composition and glucose metabolism in HFD-fed dams during pregnancy. These maternal changes persisted 10 weeks after weaning despite discontinuation of semaglutide treatment. HFD exposure impaired glucose homeostasis and promoted hepatic steatosis in offspring at 18 weeks. These effects were ameliorated by maternal semaglutide treatment. Importantly, metabolic improvements in dams and offspring occurred without adverse effects on conception rate or fetal viability. These findings suggest that GLP-1 RA during the perinatal period can improve maternal and offspring metabolic health in a mouse model of obesity and support further investigation of GLP-1-based therapies to mitigate maternal metabolic dysfunction and improve metabolic risk in children. Rates of obesity, type 2 diabetes, and fatty liver disease are rising in children, in part due to maternal obesity and insulin resistance that program offspring metabolic risk during the perinatal period.We asked whether the GLP-1 receptor agonist (GLP-1 RA), semaglutide, administered during critical developmental windows could prevent adverse outcomes in offspring using a diet-induced mouse model of maternal obesity.Semaglutide, given to dams from preconception through lactation, improved maternal metabolism and ameliorated metabolic dysfunction in offspring caused by maternal high-fat diet.These findings highlight a potential role for perinatal GLP-1 receptor agonism to improve maternal metabolic health and reduce metabolic risk in offspring.","42327723":"ID: 42327723\nTitle: Hidradenitis suppurativa and psoriasis: shared immunological links with metabolic-associated steatotic liver disease.\nAbstract: Chronic inflammatory skin conditions such as hidradenitis suppurativa and psoriasis vulgaris exhibit a significantly elevated prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD), with studies indicating rates as high as 57% among affected individuals.

However, its efficacy and regulatory mechanisms against liver injury in chicks remain unclear. In this study, a chick liver injury model was established using lipopolysaccharide (LPS) and enrofloxacin (ENR) to investigate the effects of CIRC. The results showed that dietary supplementation with 3 ‰ CIRC significantly prevented liver injury, restored growth performance, and alleviated inflammation and oxidative stress in the injured chicks. Integrated analysis of 16S rRNA gene sequencing and hepatic transcriptomics revealed a gut-liver axis-mediated mechanism for the hepatoprotective effect of CIRC. By modulating the gut microbiota, enhancing intestinal barrier function, and enriching butyrate-producing bacteria, CIRC increased butyric acid (BA) levels in both serum and liver tissue, alleviated the LPS/ENR-induced suppression of the hepatic butanoate metabolism pathway, and subsequently regulated the IL-17, Toll-like receptor, and NF-κB signaling pathways, collectively exerting a hepatoprotective effect. In conclusion, CIRC plays a crucial role in preventing chick liver injury by modulating the gut microbiota.","42330767":"ID: 42330767\nTitle: Integrating network pharmacology and in vivo evaluation reveals chicory (Cichorium intybus L.) extract activates autophagy to alleviate fatty liver hemorrhagic syndrome in laying hens.\nAbstract: Fatty liver hemorrhagic syndrome (FLHS) is a nutritional metabolic disease in poultry characterized by disrupted lipid metabolism in the liver. This study aimed to investigate the pharmacological effects and mechanisms of chicory (Cichorium intybus L.) root ethanol extract (CEE) on HELP-diet-induced FLHS. Seventy-two 50-week-old Hy-Line Brown laying hens were randomly allocated into three groups, with four replicates in each group and six hens per replicate. A standard basal diet was provided to the negative control (NC) group, whereas the other two groups were fed the high-energy low-protein (HELP) diet supplemented with 0 g/kg or 15 g/kg CEE, designated as the FLHS and CEE groups, respectively. The adaptation period lasted for 1 week, followed by a 12-week experimental period. UPLC-MS/MS-based component profiling of CEE, combined with network pharmacology analysis, identified three bioactive compounds: lactucopicrin, 2S,2'S-Aurantiamide acetate, and luteolin. Body weight was significantly increased by the HELP diet, while hens receiving CEE markedly lower body weight relative to the FLHS group at week 12 (P < 0.05 or 0.01). CEE supplementation significantly restored the laying rate, and reduced the Feed/egg ratio (P < 0.01). The FLHS group showed pronounced hepatic steatosis in laying hens, with increased TG and TC levels in serum and liver and elevated ALT and AST activities, which were markedly reversed by CEE treatment. There were 93 metabolites showing significant differences in the liver between the FLHS and CEE groups, such as 1-stearoyl-2-arachidoylglycerol, PE-NMe2, and 19-hydroxyarachidonic acid. Differentially expressed metabolites are enriched in the autophagy signaling pathway according to KEGG. CEE treatment significantly inhibited the protein levels of p-mTOR/mTOR, p62, Fasn, Acc, and Pparγ, while significantly increasing those of p-Ulk1/Ulk1, Atg5, LC3II/LC3I, and Pparα (P < 0.05 or 0.01). In conclusion, supplementation with 15 g/kg CEE effectively mitigated FLHS in laying hens by modulating hepatic lipid metabolism by activating autophagy. CEE represents a novel pharmacological strategy for FLHS treatment, highlighting chicory potential in poultry.","42331736":"ID: 42331736\nTitle: Glucagon-Like Peptide-1 Receptor Agonists and Incident Major Adverse Liver Outcomes in People With Type 2 Diabetes and Metabolic Dysfunction-Associated Steatotic Liver Disease.\nAbstract: Treatment options for metabolic dysfunction-associated steatotic liver disease (MASLD) are limited. While glucagon-like peptide-1 receptor agonists (GLP-1 RA) and sodium-glucose cotransporter-2 (SGLT-2) inhibitors improve cardiovascular outcomes, comparative effectiveness on liver-related outcomes remains unclear. This study compared the effectiveness of GLP-1 RAs versus SGLT-2 inhibitors on major adverse liver outcomes (MALO), liver cirrhosis and all-cause mortality in people with MASLD and type 2 diabetes. This active comparator, new-user cohort study used claims data from Germany (2005-2024), including 45 256 people with MASLD and type 2 diabetes. New users of GLP-1 RAs (n = 9993) and SGLT-2 inhibitors (n = 35 263) were weighted using matching weights. The primary outcome was MALO, while secondary outcomes comprised individual MALO components (decompensation events, liver transplantation, hepatocellular carcinoma (HCC)), liver cirrhosis and all-cause mortality. Hazard ratios (HR) with 95% confidence intervals (CI) were estimated with weighted Cox proportional hazard models. Over a median 4.3-year follow-up, new users of GLP-1 RAs had a lower hazard of MALO (HR 0.91, 95% CI 0.78-1.07). This association appeared stronger using an on-treatment approach (HR 0.78, 95% CI 0.58-1.03) and when restricting to hospital diagnoses in primary position (HR 0.77, 95% CI 0.56-1.07). Benefits were also observed for liver cirrhosis (HR 0.88), decompensation events (HR 0.91), HCC (HR 0.76), but not all-cause mortality (HR 1.04). GLP-1 RAs were associated with a potentially lower hazard for incident MALO and liver cirrhosis compared with SGLT-2 inhibitors in people with MASLD and type 2 diabetes, suggesting a possible therapeutic advantage for liver-specific outcomes in this population.","42332507":"ID: 42332507\nTitle: Therapeutic effects and mechanisms of Artemisia species on metabolic diseases: A systematic review.\nAbstract: The prevalence of metabolic disorders has increased significantly in recent years, driving interest in effective herbal remedies.

Studies evaluating Artemisia species for metabolic diseases (diabetes, hyperlipidemia, nonalcoholic fatty liver disease, obesity, or gout) were included. The included studies were analyzed and compared in terms of research types (animal, human, and in vitro studies), therapeutic outcomes, and mechanistic pathways. A qualitative synthesis was performed. Numerous experiments have demonstrated the efficacy of 28 Artemisia species in lowering blood sugar and lipid levels, stimulating insulin secretion, ameliorating insulin resistance, suppressing inflammation and oxidative stress, reducing fat synthesis, and modulating the gut microbiota. These findings underscore their potential as promising therapeutic candidates for the management of metabolic disorders. This review acts as a crucial guide for steering the progress of drug development and the therapeutic use of Artemisia plants in addressing metabolic diseases. However, clinical investigations into the effects of Artemisia on metabolic disorders in humans are still limited. Further trials are essential to validate its effectiveness in treating these ailments.","42337165":"ID: 42337165\nTitle: Potential targets of baicalein in macrophages revealed by bulk and single cell RNA sequencing analysis.\nAbstract: Excessive inflammation drives organ dysfunction and high mortality in life-threatening conditions such as sepsis. Baicalein, a bioactive flavonoid, possesses well-recognized anti-inflammatory properties, yet its molecular targets in macrophages and potential systemic immunomodulatory effects on peripheral blood immune cells under hyperinflammatory conditions remain poorly characterized. Our previous studies demonstrated that baicalein alleviates hepatic inflammation in mice with non-alcoholic fatty liver disease (NAFLD) and inhibits NF-κB nuclear translocation in RAW264.7 macrophages. Here, by integrating network pharmacology, molecular docking, bulk RNA sequencing of macrophages, and single-cell RNA sequencing of peripheral blood from sepsis patients, we identified JAK2, SRC, TP53, MAPK3, AKT1, HSP90AA1, and ESR1 as potential core targets of baicalein in macrophages, and validated that the JAK2-STAT3 and NF-κB pathways might be the key downstream regulatory axes of its anti-inflammatory effects. Furthermore, we revealed that baicalein may modulate, based on single-cell expression signatures, the inflammatory phenotype of multiple peripheral blood immune cell populations, including monocytes, T cells, B cells, and granulocyte-monocyte progenitors, suggesting a potential systemic anti-inflammatory effect that requires experimental validation in human cells. Collectively, our findings elucidate the potential molecular targets of baicalein in macrophages and its multi-cellular immunoregulatory mechanisms under hyperinflammation, providing novel mechanistic insights for the clinical application of baicalein in inflammatory diseases.","42339503":"ID: 42339503\nTitle: The correlation between periodontitis and fatty liver and the improvement of NAFLD by periodontal treatment.\nAbstract: Emerging evidence highlights a pathophysiological interplay between periodontitis and non-alcoholic fatty liver disease yet the mechanistic underpinnings and therapeutic implications remain contentious. This review systematically elucidates molecular crosstalk through the \"oral-gut-liver axis\" and \"oral-liver axis\". A comprehensive literature review was conducted using PubMed, Scopus and Web of Science, employing keywords related to periodontal disease and non-alcoholic fatty liver disease. Analysis of 16 original studies revealed that periodontitis and its associated pathogens promote the progression of non-alcoholic fatty liver disease through multiple pathways: (1) activation of hepatic inflammatory responses (elevated IL-6, IL-17, and TNF-α levels), (2) exacerbation of metabolic dysregulation (increased HOMA-IR, ALT, and AST), and (3) disruption of the oral-gut-liver axis. Notably, non-surgical periodontal therapy demonstrated therapeutic potential by simultaneously improving periodontal health and attenuating non-alcoholic fatty liver disease progression through reduction of hepatic pro-inflammatory cytokines and fibrogenic mediators. Periodontitis may exacerbate systemic inflammation via the oral-liver and oral-gut-liver axes, inducing insulin resistance and promoting non-alcoholic fatty liver disease. Non-surgical periodontal therapy can improve non-alcoholic fatty liver disease, but methodological heterogeneity in current studies necessitates further prospective research to clarify their relationship.","42344908":"ID: 42344908\nTitle: Polysaccharides-gut microbiota interaction: mechanisms regulating the hepatocellular carcinoma immune microenvironment.\nAbstract: Hepatocellular carcinoma (HCC) has a poor prognosis, and the clinical responses to immune checkpoint inhibitors (ICIs) remain limited. Increasing evidence suggests that gut microbiota dysbiosis plays an important role in HCC progression through the gut-liver axis. This review summarizes the mechanisms by which polysaccharide-gut microbiota interactions reshape the immunosuppressive tumor microenvironment (TME) in HCC, and discusses the translational potential and challenges of this emerging therapeutic axis. Specifically, gut microbiota dysbiosis promotes chronic hepatic inflammation and immunosuppression through metabolites such as lipopolysaccharide, short-chain fatty acids, and bile acids. As biocompatible prebiotics, natural polysaccharides can selectively enrich beneficial gut bacteria, including Bacteroides and Akkermansia, promote the production of immunoregulatory metabolites, and regulate key signaling pathways such as TLR/NF-κB, bile acid-FXR, and PD-1/PD-L1. Nanopolysaccharides designed to improve tumor-targeting efficiency are also being explored in preclinical studies for HCC. Despite the therapeutic potential of the gut microbiota-polysaccharide-liver TME axis, several challenges remain, including polysaccharide structural heterogeneity, unclear microbiota-immune causal relationships, and undefined safe dose windows. Overall, this review provides an integrated overview of polysaccharide-based modulation of the HCC immune microenvironment and may offer insights for the development of more precise therapeutic strategies according to HCC etiological heterogeneity.","42345773":"ID: 42345773\nTitle: Dietary Chlorogenic Acid Attenuates Hepatic Lipid Accumulation and Reprograms Lipid Metabolism in Heat-Stressed Laying Hens: Integrated Transcriptomic and Metabolomic Analyses.\nAbstract: Heat stress leads to excessive hepatic lipid deposition and oxidative imbalance in laying hens, especially during peak laying period. Chlorogenic acid (CGA), a dietary polyphenol with antioxidant and lipid-modulating properties, may improve hepatic lipid homeostasis, yet its effects under heat-stress conditions remain unclear. In this study, 240 Hy-Line Brown laying hens at 36 weeks of age were randomly assigned to one of two treatments (120 hens per treatment, with six replicates of 20 hens each): a basal diet or a basal diet supplemented with 300 mg/kg CGA and subjected to heat-stress conditions for 8 weeks. CGA supplementation significantly reduced liver weight (25.3%), liver index (14.4%), hepatic triglyceride content (29.1%), and serum triglyceride level (61.7%) (p < 0.05). Histological assessment revealed lower steatosis and inflammation scores, alongside increased hepatic SOD activity (13.6%) and decreased MDA content (58.7%) (p < 0.05). RNA-seq analysis identified 420 differentially expressed genes that were significantly enriched in PPAR signaling and fatty acid β-oxidation pathways. CGA upregulated fatty acid oxidation-related genes (ACSL1, CPT1A, ACOX1, ACAA1) and downregulated lipogenic markers (FASN, ACACA). Serum metabolomics revealed coordinated changes in lipid and carbon metabolism. These results indicate that dietary CGA alleviates hepatic lipid accumulation and oxidative stress in heat-stressed peak-laying hens, potentially via PPARα-mediated enhancement of fatty acid oxidation and inhibition of de novo lipogenesis.","42346116":"ID: 42346116\nTitle: The Gut-Brain-Immune Axis: Multi-Omics Insights into Neurodegenerative and Metabolic Diseases.\nAbstract: The axis linking the gut to the brain to the immune system connects all tissues involved-bacteria, immune cells, metabolism and the CNS-through a multidirectional communication network. Several studies have confirmed that when this axis is disrupted, it can be responsible for Alzheimer's disease, Parkinson's disease, obesity, type 2 diabetes, and NAFLD, and the main consequences come from increased systemic inflammation, altered regulation of immune cells, the production of microbial metabolites that alter signals to the immune cells and nervous system, increase in oxidative stress, breakdown of the gut barrier, and more. In recent years, advanced multi-omics technologies, such as metagenomics, transcriptomics, metabolomics, proteomics, and single-cell sequencing, have provided significant advancement in our understanding of all of the interacting nodes involved in the gut-brain-immune axis. These advanced sequencing technologies can characterize the microbial communities, host immune cells, metabolic profiles, and the degree of cell heterogeneity during a specific disease. Combining multi-omics information can reveal a few shared pathways between neurodegenerative and metabolic disorders, such as NF-κB, NLRP3 inflammasome activation, mitochondrial dysfunction, changes in SCFA metabolism, and the alteration of microbial populations in Alzheimer's and Parkinson's disease; metabolic dysbiosis and increased risk for Parkinson's disease; or changes in gut-to-brain-to-immune signaling contributing to diabetes complications and NAFLD. Artificial intelligence (AI) and machine learning are becoming promising tools for detecting biomarkers from these datasets, extracting knowledge, interpreting systems biology, and helping with developing precision medicine. In this review, we summarize current evidence that supports the role of the gut-brain-immune axis in neurodegenerative and metabolic diseases, highlighting results gained with the utilization of multi-omics approaches. We will describe the key microbial, immune, and metabolic pathways involved in pathogenesis and therapeutic approaches including psychobiotics, tailored nutrition, modulation of the microbiome, and metabolite interventions, discussing future perspectives of the translation of the gut-brain-immune axis knowledge into clinical practice.","42346379":"ID: 42346379\nTitle: Nervonic Acid Prevents HFD-Induced Metabolic Dysfunction and Is Associated with Gut Microbiota Remodeling.\nAbstract: Obesity is closely associated with gut microbiota dysbiosis. Nervonic acid (NA; (15Z)-15-tetracosenoic acid) is a bioactive fatty acid with reported metabolic effects. This study aimed to investigate the associations between NA administration, gut microbiota composition changes, and host metabolic phenotypes in high-fat diet (HFD)-fed mice. C57BL/6J mice were fed an HFD for 12 weeks and concurrently administered NA at doses of 20, 40, and 60 mg/(kg·d) by gavage. Metabolic parameters, histopathological changes, and fecal microbiota composition (via 16S rRNA gene sequencing) were evaluated. NA administration was associated with significantly attenuated HFD-induced increases in body weight and adipose tissue mass, as well as marked reductions in serum total cholesterol, triglycerides, and low-density lipoprotein cholesterol (all p < 0.05). Hepatic steatosis and adipose tissue inflammation were also attenuated. 16S rRNA gene sequencing revealed that NA was associated with the counteraction of HFD-induced gut microbiota dysbiosis, including alterations in α-diversity and community structure. NA was associated with higher relative abundances of taxa such as Blautia, Oscillibacter, Faecalibaculum, Parabacteroides, Dubosiella, and Odoribacter and lower relative abundances of Lachnoclostridium, Mucispirillum, and Alistipes. Within-group correlation analyses showed that genera with higher relative abundances were inversely associated with lipid parameters and adiposity, whereas genera with lower relative abundances correlated positively with these metabolic indicators. NA administration was associated with bidirectional changes in gut microbiota composition-the enrichment of certain taxa and the suppression of others-concomitant with the amelioration of HFD-induced metabolic dysfunction. These findings indicate correlations between NA, gut microbiota alterations, and improved metabolic phenotypes; however, causality remains to be established.","42346391":"ID: 42346391\nTitle: Multi-Targeted Intervention of Eucommia ulmoides and Its Bioactive Constituents Against Metabolic Syndrome: From Molecular Mechanisms and Gut Microbiota Modulation to Clinical Translation.\nAbstract: Background/Objectives: Metabolic syndrome (MetS) is a pressing global health challenge comprising obesity, hyperglycemia, hypertension, and hyperlipidemia. Conventional polypharmacy often presents long-term compliance issues and side effects. Eucommia ulmoides Oliv., a traditional medicinal and edible plant rich in iridoids, lignans, flavonoids, and polysaccharides, has emerged as a promising natural intervention. This review aims to systematically summarize the bioavailability and multifaceted pharmacological mechanisms of E. ulmoides and its bioactive components in alleviating MetS. Methods: We comprehensively reviewed the recent in vitro and in vivo literature to map the functional evidence, specific signaling pathways, and gut microbiota-host interactions associated with E. ulmoides extracts and its key phytochemicals (e.g., asperuloside) against various metabolic dysfunctions. Results: Current evidence indicates that E. ulmoides operates through a \"multi-component, multi-target, and multi-pathway\" paradigm. For hyperlipidemia and obesity, it activates hepatic lipid metabolism (PPARα/CPT1A, FXR/CYP7A1) and mitigates oxidative stress (Nrf2/ARE). Furthermore, it dose-dependently reshapes the gut microbiota by enriching beneficial bacteria like Akkermansia and increasing butyrate production, exerting profound gut-liver axis regulation. It also ameliorates hypertension by activating the ACE2-Ang-(1-7)-Mas axis, improves insulin resistance via the AMPK/PI3K/Akt cascade, and manages hyperuricemia by modulating XOD and renal transporters. Notably, the low oral bioavailability of its glycosides highlights the crucial role of gut microbial hydrolysis in its efficacy. Conclusions: E. ulmoides holds substantial therapeutic potential as a multi-target natural supplement for MetS. However, future translational applications necessitate large-scale randomized clinical trials, multi-omics studies to further clarify host-microbiome interactions, and the development of standardized formulations to ensure clinical efficacy.","42348222":"ID: 42348222\nTitle: Cost-Effectiveness of Pharmacologic Therapies for Metabolic Dysfunction-Associated Steatohepatitis With Significant Fibrosis in the United States.\nAbstract: The approval of new pharmacotherapies for metabolic dysfunction-associated steatohepatitis (MASH) presents a critical need for value assessment. We evaluated the cost-effectiveness of resmetirom, semaglutide and tirzepatide for U.S. adults with MASH and F2-F3 fibrosis. We developed a Markov cohort model with a lifetime horizon from the perspective of a U.S. healthcare payer. The model simulated biopsy-confirmed patients with MASH progressing through liver-specific health states. Efficacy inputs for fibrosis regression and MASH resolution were obtained from a Bayesian network meta-analysis. Each pharmacotherapy was compared individually against standard of care; a formal sequential incremental analysis across active therapies was not performed. Cost-effectiveness was assessed against the standard of care using a $100 000/QALY willingness-to-pay threshold. In the base-case analysis, tirzepatide had the largest QALY gain and the lowest incremental cost relative to standard of care, yielding an incremental cost-effectiveness ratio of ($42 705/QALY). Semaglutide was also cost-effective (ICER: $80 076/QALY). Resmetirom (ICER: $273 445/QALY) exceeded the WTP threshold. Drug price was the most influential parameter in sensitivity analyses; probabilistic sensitivity analysis showed a 99.5% probability of cost-effectiveness for tirzepatide and 89.8% for semaglutide at $100 000/QALY. At current U.S. prices, tirzepatide and semaglutide are cost-effective for MASH with F2-F3 fibrosis, while resmetirom is not. The tirzepatide finding should be interpreted with caution, given that it is not yet FDA-approved for MASH and its effect estimate is based on a network meta-analysis of a phase 2 trial. Payer coverage and equitable access to MASH therapies require value-based pricing strategies.","42349743":"ID: 42349743\nTitle: Maternal butyrate administration ameliorates fetal fatty liver and maternal metabolic alterations related to maternal obesity.\nAbstract: Obesity negatively impacts maternal and fetal metabolism, leading to the programming of metabolic disturbances in the offspring. We have previously reported numerous maternal, fetal and offspring alterations in a rat model of obesity. In this study, we administered butyrate-a short-chain fatty acid derived from gut microbiota metabolism-to obese mother rats during pregnancy and lactation in an attempt to improve maternal health and prevent the fetal features associated with the programming of fatty liver disease. The initial experimental study design comprised female Albino-Wistar rats assigned to either a control diet (C group) or a high-fat diet (FD group) to induce obesity, before being paired with control males. Pregnant rats received either butyrate (CB or FDB) or water as a vehicle (C or FD) during gestation and were euthanized at day 21 of pregnancy. The second experimental design comprised C, FD, and FDB rats that gave birth and breastfed their pups, with mothers being euthanized at the conclusion of the lactation period. At term gestation, rats with obesity exhibited increased adiposity, hepatic lipid accumulation, triglyceridemia, and circulating IL-1β. Their fetuses displayed increased body weight, liver lipid over-accumulation, and altered mRNA levels of genes involved in liver damage. Notably, butyrate administration decreased maternal circulating levels of triglycerides and IL-1β, and prevented fetal overweight status and hepatic lipid accumulation at term gestation. Importantly, butyrate exerted no effect on control rats or their fetuses. Moreover, butyrate administration ameliorated features of fatty liver disease in overweight rats at the end of lactation, further demonstrating its beneficial effects on both mothers and fetuses in this rat model of obesity.","42349829":"ID: 42349829\nTitle: Novel genetic insights into causal effects of depression on non-alcoholic fatty liver diseases partially mediated by gut microbiota.\nAbstract: Depression and non-alcoholic fatty liver disease (NAFLD) are increasingly recognized as interconnected disorders, yet the causal mechanisms linking them remain unclear. Using univariable and multivariable Mendelian randomization (MR), we demonstrated that depression causally increased the risk of NAFLD (P = 8.473 × 10-8, OR = 1.944, 95% CI: 1.524 to 2.479), independent of major metabolic confounders. Mediation analysis further identified the gut microbial genus Phascolarctobacterium as a partial mediator of this effect (P = 0.0328, β = 0.145, 95% CI: 0.0119 to 0.278), with a mediated proportion of 21.818%. By integrating genetic mapping, transcriptomic profiling, and machine learning, we identified MICAL2 as a central hub gene linking depression-associated genetic variation to NAFLD. Furthermore, single-cell analysis revealed MICAL2-associated gene signatures are linked to macrophage dysfunction in NAFLD. Besides, molecular docking and dynamics simulations suggested that sanguinarine might target MICAL2 with stable binding affinity, highlighting a potential therapeutic avenue. Finally, experimental validation confirmed MICAL2 overexpression in liver tissues of NAFLD mouse models. Together, our findings support a mechanistic framework in which depression promotes NAFLD through a microbiota-mediated pathway converging on MICAL2 and macrophage dysfunction. These findings might have implications for risk stratification and early intervention of depression-induced NAFLD patients and offer novel insights into the brain-gut-liver interactions.","42351370":"ID: 42351370\nTitle: Pomegranate seed oil attenuates palmitic acid-induced hepatic injury through modulation of oxidative stress: insights from GC-Q-TOF-MS-based metabolomics.\nAbstract: Non-alcoholic fatty liver disease (NAFLD) is a leading cause of chronic liver disease worldwide, with oxidative stress and lipid dysregulation as central pathogenic drivers. Pomegranate seed oil (PSO), rich in the conjugated fatty acid punicic acid, has demonstrated potential antioxidant and lipid-modulating properties, yet its hepatoprotective mechanisms remain incompletely characterized at the metabolic level. Gas chromatographic-mass spectrometric analysis of the fatty acid composition of supercritical CO2-extracted PSO revealed that punicic acid was the predominant fatty acid, comprising 74.47% of the total identified fatty acids, which collectively accounted for approximately 95% of the fatty acid profile. In palmitic acid (PA)-challenged C57BL/6 mice, PA administration significantly increased serum and hepatic lipid levels, liver function markers, oxidative stress indicators, and inflammatory cytokines. PSO intervention dose-dependently ameliorated several of these abnormalities and markedly reduced hepatic lipid accumulation. Gas chromatography-quadrupole time-of-flight mass spectrometry-based serum metabolomics revealed that PSO markedly reversed PA-induced metabolic disturbances, identifying 27 key differential metabolites predominantly associated with amino acid and lipid metabolism. Pathway enrichment analysis highlighted oxidative stress-related pathways, including glutamate, taurine, and fatty acid metabolism. PSO significantly upregulated antioxidant metabolites (cysteine, glutamate, hypotaurine, α-tocopherol) while downregulating oxidative markers (uric acid, xanthine). Complementary in vitro experiments in PA-treated L02 human hepatocytes further demonstrated that PSO alleviated lipotoxicity by attenuating reactive oxygen species generation and preserving membrane integrity. These findings demonstrate that PSO exerts hepatoprotective effects through multi-target, multi-pathway synergistic mechanisms, particularly via enhancing endogenous antioxidant defense systems, providing scientific evidence for PSO as a promising nutritional intervention strategy for NAFLD prevention and treatment. © 2026 Society of Chemical Industry.","42351716":"ID: 42351716\nTitle: Lack of Galectin-3 Disturbs Gut-Adipose-Liver Axis in High-Fat-Diet Mice Model.\nAbstract: Background/Objectives: A high-fat diet (HFD) promotes hepatic steatosis, inflammation, and systemic metabolic imbalance. Notably, HFDs can affect the gut-liver axis and adipose tissue homeostasis. Galectin-3 (Gal-3) binds to β-galactosides and plays regulatory roles in the gut-liver axis, connecting metabolic stress with inflammation and tissue remodelling. The objective of this study was to investigate whether Gal-3 affects the gut-liver axis and adipose tissue biology after HFD supplementation. Methods: Six-week-old C57BL/6 mice were randomly divided into either wild-type (Lgals3+/+) or knockout (Lgals3-/-) groups. Both groups received an HFD orally for 12 weeks, along with their respective control groups. Physiological measurements and microscopic examination of the gut, liver, and fat tissue were conducted using optical microscopy. Results: The HFD induced obesity in Lgals3+/+ mice, but not in Lgals3-/- mice, which exhibited lower weight gain, food intake, daily energy intake, and energy efficiency than Lgals3+/+ mice. Moreover, Lgals3-/- HFD mice had hyperglycaemia and hyperinsulinemia. Histological analysis revealed hypertrophied adipose tissue in Lgals3+/+ HFD mice with abundant Gal-3+ crown-like structures, rarely observed in Lgals3-/- HFD mice. In the jejunum, Lgals3+/+ HFD mice showed a significant reduction in Gal-3 expression in intestinal epithelial cells, whereas inflammatory signals were increased in Lgals3-/- HFD mice. In the liver, Lgals3+/+ HFD mice showed significant steatosis and macrophages expressing Gal-3. In contrast, Lgals3-/- HFD mice showed pronounced hepatocyte ballooning, suggesting a more progressive stage of metabolic dysfunction-associated steatotic liver disease (MASLD). Conclusions: Together, these data suggest that Gal-3 protects the gut-liver axis and adipose tissue against cytotoxic effects caused by HFD.","42352033":"ID: 42352033\nTitle: Probiotic Modulation of Gut Microbiota: Antioxidant Mechanisms and Clinical Benefits in Obesity and Type 2 Diabetes Management.\nAbstract: Obesity and type 2 diabetes mellitus (T2DM) represent intertwined global epidemics driven by gut dysbiosis, chronic inflammation, and impaired SCFA production, identifying the microbiome as a therapeutic target. This review synthesizes mechanistic insights and clinical evidence on the role of probiotics as microbiome modulators in the management of metabolic disease. A comprehensive literature search across PubMed, Scopus, Web of Science, and Google Scholar up to May 2026 identified ~230 records using keywords such as probiotics, SCFAs, obesity, and T2DM; a narrative synthesis integrated preclinical, RCT, and meta-analytic data without formal pooling due to heterogeneity. Probiotics restore eubiosis via strain-specific mechanisms, Lacticaseibacillus rhamnosus GG enhances tight junctions (ZO-1), Bifidobacterium breve BBr60 boosts butyrate cross-feeding, and pasteurized Akkermansia muciniphila remodels bile acids (FXR/FGF19), activating G-Protein Coupled Receptor 41 (GPR41)/43-GLP-1 signaling, Treg expansion, and NF-κB suppression. Beyond immunometabolic effects, probiotics mitigate obesity- and T2DM-related oxidative stress by upregulating endogenous antioxidant enzymes (e.g., SOD, catalase, GPx), modulating Nrf2/Keap1 signaling, and reducing lipid peroxidation and other oxidative stress markers in experimental and clinical settings. Meta-analyses of RCTs reveal modest benefits: BMI reductions (~0.3 kg m-2), waist circumference (WC) reductions (1-2 cm), HbA1c reductions (0.3-0.4%), and improvements in homeostatic model assessment of insulin resistance (HOMA-IR), especially with multi-strain (>109 CFU day-1, ≥12 weeks) synbiotics. Innovative strategies-synbiotics, postbiotics, AI-tailored consortia, and fermented dairy-address engraftment and response variability. Current guidelines recommend 109-1011 CFU day-1 using multi-strain formulations for 12-24 weeks alongside lifestyle measures, with regimen selection tailored to the dysbiosis phenotype (e.g., NAFLD). Future longitudinal RCTs integrating multi-omics endpoints with AI-driven strain selection should refine-and ultimately individualize-precision probiotic strategies for metabolic therapy.","42352035":"ID: 42352035\nTitle: Sex-Specific and Reproductive Status-Dependent Effects of Liraglutide on Metabolic Disorders Associated with Prediabetes.\nAbstract: Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have been shown to have beneficial effects in T2D, reducing hepatic lipid storage and improving metabolic dysfunction-associated steatotic liver disease. However, sex and reproductive age may influence their effect. We investigated the effect of liraglutide administration (0.2 mg/kg/day subcutaneously for 8 weeks) on metabolic disorders in relation to sex and reproductive age, using male, female and ovariectomized female hereditary hypertriglyceridemic (HHTg) rats as a prediabetic model. Liraglutide improved glucose tolerance in all HHTg rats. Female and ovariectomized (OVX) female rats showed a stronger effect of lipid metabolism and visceral adiposity than males. Moreover, no changes in hepatic triacylglycerol (TAG) accumulation were observed in males. Liraglutide partially reversed ovariectomy effects, such as increased body weight, visceral obesity and impaired glucose tolerance. Compared with males, female and OVX female rats showed more significant changes in hepatic gene expression involved in lipogenesis (Scd-1, Srebp1, Pparγ), fatty acid and lipid metabolism (Pparα, Hmgcr, Srebp2) and fibrosis (Tgfβ), which may improve hepatic lipid metabolism. Females of fertile age showed greater improvements in insulin sensitivity, reductions in ectopic lipid accumulation, and improvements in lipid metabolism. Depending on sex and reproductive status, liraglutide can mitigate fatty liver before diabetes onset.","42352893":"ID: 42352893\nTitle: Impact of Air Pollution on Metabolic Dysfunction-Associated Fatty Liver Disease.\nAbstract: Metabolic dysfunction-associated fatty liver disease (MAFLD) is now recognized as a leading form of chronic liver disease globally and is strongly associated with metabolic abnormalities. Traditionally, the pathogenesis of MAFLD has mainly been attributed to genetic susceptibility and unhealthy lifestyles (such as high-calorie diets and sedentary behavior). However, in recent years, environmental factors, especially air pollution, have been confirmed as independent risk factors and important promoting factors for MAFLD development and further disease progression. This review summarizes current epidemiological findings on the link between air pollution exposure and MAFLD, while exploring its potential biological mechanisms involving systemic inflammation, oxidative stress, immune alteration, genetic risk, and epigenetic regulation underlying the relationship between air pollution and hepatic steatosis. It also reviews the additive interaction between air pollution and lifestyle or socioeconomic factors in MAFLD. Finally, we also discuss multilevel strategies spanning individual-, community-, national-, and global-level cooperation to address the increasing public health burden caused by air pollution. Therefore, incorporating the assessment and control of air pollution into the comprehensive strategies for MAFLD prevention and treatment has important scientific value and public health significance.","42353191":"ID: 42353191\nTitle: Akkermansia muciniphila Alleviates Enterococcus faecalis-Exacerbated Alcoholic Liver Injury by Modulating Gut Microbiota and Barrier Function.\nAbstract: Cytolysin-positive Enterococcus faecalis is a key pathogen in severe alcoholic hepatitis, yet the mechanisms through which it worsens disease and possible therapeutic strategies remain poorly understood. This study aimed to clarify the pathogenic effects of E. faecalis in acute alcohol-associated liver disease (ALD) and to assess the protective potential of Akkermansia muciniphila (Akk11) against this pathogen. Using a mouse model of acute ethanol gavage, animals received E. faecalis and/or Akk11 under prophylactic or therapeutic regimens. Assessments included liver injury markers, histopathology, lipid profiles, inflammatory cytokines, gut barrier integrity, and gut microbiota composition. E. faecalis exacerbated ethanol-induced hepatic steatosis and injury, showing a paradoxical effect: it increased histological damage while lowering circulating LPS and transaminases. This was linked to upregulated hepatic autophagy (increased Atg7) and reduced cholesterol, yet it promoted neutral lipid accumulation. Importantly, E. faecalis aggravated gut dysbiosis by markedly enriching the pro-inflammatory pathobiont Helicobacter typhlonius and impairing colonic barrier function. Intervention with Akk11 alleviated liver injury, reduced lipid accumulation and oxidative stress, and restored cytokine balance. Akk11 also strengthened gut barrier integrity, lowered serum endotoxin, and beneficially reshaped the microbiota. Prophylactic administration was particularly effective, normalizing the Firmicutes/Bacteroidota ratio, suppressing H. typhlonius, and enriching beneficial Bacteroides sartorii. This study confirms the pathogenic role of E. faecalis in acute ALD and establishes A. muciniphila (Akk11) as a promising microbiota-targeted therapy, which protects against liver injury by reinforcing the gut barrier, selectively modulating microbiota, and reducing inflammation, with prophylactic administration showing superior efficacy.","42353331":"ID: 42353331\nTitle: Therapeutic Effects of Glucagon-like Peptide-1 Receptor Agonists in Non-Alcoholic Fatty Liver Disease: A Systematic Review.\nAbstract: Non-alcoholic fatty liver disease (NAFLD), now increasingly termed metabolic dysfunction-associated steatotic liver disease (MASLD), is a growing cause of chronic liver disease with limited treatment options. Glucagon-like peptide-1 (GLP-1) receptor agonists, approved for type 2 diabetes and obesity, possess metabolic effects that may render them suitable for treating NAFLD and metabolic dysfunction-associated steatohepatitis (MASH). To evaluate the therapeutic effects of GLP-1 receptor agonists in adults with NAFLD, non-alcoholic steatohepatitis (NASH), MASLD, or MASH. PubMed, Scopus, Embase, and the Cochrane Library were systematically searched using keywords related to NAFLD and GLP-1 receptor agonists. Given heterogeneity in populations, designs, and outcomes, findings were synthesized narratively. The review is registered with PROSPERO (CRD420261337353). Twelve studies met the inclusion criteria. The most consistent outcome was a reduction in hepatic fat, seen with semaglutide, liraglutide, dulaglutide, and beinaglutide. Improvements in liver enzymes, particularly alanine aminotransferase, were less consistent and best regarded as supportive rather than definitive evidence of histological improvement. Histological benefits were strongest for steatohepatitis resolution in non-cirrhotic MASH. Fibrosis findings were mixed, with the greatest benefit in F2-F3 MASH and limited improvement in established cirrhosis. GLP-1 receptor agonists were generally well tolerated, with gastrointestinal symptoms the most common adverse effects. GLP-1 receptor agonists show promising liver-related benefits in NAFLD and MASH, particularly in obesity, type 2 diabetes, or earlier-stage disease. Their effects on advanced fibrosis and long-term outcomes remain uncertain, warranting larger, longer-term studies.","42353596":"ID: 42353596\nTitle: Niemann-Pick C1-Like 1 in Cholesterol Absorption and Homeostasis: Mechanisms, Regulation, and Emerging Phytochemical Inhibitors.\nAbstract: Disruption of cholesterol homeostasis is closely associated with hypercholesterolemia, dyslipidemia, atherosclerotic cardiovascular disease (ASCVD), and metabolic disorders such as metabolic dysfunction-associated fatty liver disease (MAFLD). Intestinal and hepatic cholesterol absorption are central to maintaining systemic cholesterol balance, with Niemann-Pick C1-Like 1 (NPC1L1) acting as a key transporter that mediates cholesterol uptake in enterocytes and hepatocytes. Aberrant NPC1L1 expression or activity promotes excessive cholesterol accumulation in both plasma and liver, thereby contributing to dyslipidemia and hepatic steatosis. Consequently, NPC1L1 has emerged as an important therapeutic target for reducing cholesterol absorption and improving lipid homeostasis. Although ezetimibe is currently the only clinically approved NPC1L1 inhibitor, its limited efficacy as monotherapy highlights the need for alternative or complementary therapeutic strategies. Growing evidence indicates that natural phytochemicals, particularly polyphenols and flavonoids, can modulate NPC1L1 at both transcriptional and functional levels. These compounds not only suppress intestinal cholesterol absorption but also attenuate hepatic lipid accumulation, ultimately improving circulating lipid profiles. This review summarizes recent advances in understanding the role of NPC1L1 in cholesterol metabolism and highlights the emerging therapeutic potential of phytochemicals as novel complementary approaches for the prevention and treatment of lipid metabolic disorders.","42354127":"ID: 42354127\nTitle: Flavonoids as Nutraceuticals to Treat Inflammatory Diseases: Focusing on Quercetin, Kaempferol, Luteolin, Apigenin, Epicatechin and Their Effects on Hepatic, Nervous, and Pulmonary Systems.\nAbstract: The immune response is essential in the protection of our body against pathogens; however, the inflammatory response caused by the immune system can become a disease itself. In fact, anti-inflammatory and immune-suppressive drugs are applied to limit the immune response to treat inflammatory diseases. Flavonoids are plant-derived polyphenols extensively investigated for their anti-inflammatory and antioxidant properties in inflammatory diseases. Studies applying isolated compounds as well as using supplements as nutraceuticals based on flavonoids have been conducted. Our review systematically analyzed the top five studied flavonoids between 2020 and 2025: quercetin (1742 articles), kaempferol (642), luteolin (589), apigenin (419), and epicatechin (354), highlighting their major therapeutic applications in diseases affecting the liver (12%), nervous system (11%), and lungs (10%). Mechanistically, these compounds act as multi-target agents mainly by inhibiting NF-κB and inducing Nrf2-dependent antioxidant programs. Application of advanced delivery systems, which increase oral bioavailability by up to 20-fold, overcomes pharmacokinetic bottlenecks. Clinical highlights demonstrated promising therapeutic effects, including reduced intrahepatic lipid accumulation in non-alcoholic fatty liver disease patients following quercetin supplementation (11.5% to 9.6%) and accelerated SARS-CoV-2 clearance after quercetin phytosome administration. The translation of flavonoids into standardized clinical therapies remains limited by the lack of large-scale, well-controlled clinical trials.","42354872":"ID: 42354872\nTitle: Oleanolic Acid Modulates the Gut-Liver Axis to Alleviate High-Fat Diet-Induced Hepatic Lipid Deposition in Nile Tilapia (Oreochromis niloticus).\nAbstract: This study examined the protective mechanisms of oleanolic acid (OA) against high-fat diet (HFD)-induced hepatic steatosis and intestinal dysbiosis in Nile tilapia. Fish were allocated to four groups: normal diet (ND), HFD, and OA-supplemented HFD (50 and 250 mg/kg). After 42 days, physiological, biochemical, and histological assessments demonstrated that OA markedly reduced hepatic lipid accumulation, mitochondrial injury, and intestinal shortening. Transcriptomic analysis revealed that OA alleviated lipid dysregulation by inhibiting de novo lipogenesis and promoting lipid trafficking and β-oxidation, effectively reversing HFD-induced changes in the PPAR, MAPK, mTOR, and autophagy-lysosome signaling pathways. 16S rRNA sequencing indicated that OA increased microbial alpha diversity, suppressing HFD-associated taxa (e.g., Nordella) while enriching beneficial genera such as Clavibacter, Bosea, and Bdellovibrio. Importantly, OA treatment restored HFD-induced depletion of intestinal butyric acid and suppressed hepatic pro-inflammatory cytokines (tnf-α, il-1β), while upregulating growth-related factors (igf1). Correlation analysis confirmed strong associations between microbial alterations (Nordella and Phreatobacter) and hepatic lipid metabolism and inflammatory gene expression. Overall, OA mitigates metabolic stress in Nile tilapia by reconfiguring the gut-liver axis, integrating microbial restoration with precise regulation of hepatic nutrient-sensing and inflammatory pathways, providing a potential therapeutic strategy for lipid metabolism disorders in aquaculture.","42356241":"ID: 42356241\nTitle: Dietary α-Tocopherol Deficiency Disrupts Hepatic Circadian Clock and Lipid Metabolism in Association with Gut Microbiota Dysbiosis.\nAbstract: Background/Objectives As a fat-soluble vitamin, vitamin E (VE) is prone to suboptimal intake in the general population. Alpha-tocopherol (α-TE) represents the most biologically significant form of VE in vivo. Nevertheless, the potential detrimental effects of α-TE deficiency on health remain unclear. This study was conducted to investigate the effect of α-TE deficiency on hepatic metabolism and gut microbiota. Methods C57BL/6J mice were randomly assigned to receive one of three dietary regimens: a α-TE-deficient diet, a control diet with normal α-TE, or a high-dose diet containing four times the normal α-TE level. Histopathology, serum biochemistry, RNA-Seq, RT-qPCR, Western blot, and 16S rRNA gene sequencing with correlation analysis were used to assess metabolic phenotypes, hepatic circadian, hepatic lipid metabolism, and cecal microbiota, respectively. Results The results demonstrated that α-TE deficiency induced hepatic steatosis and lipid metabolic disturbances. α-TE deficiency significantly decreased Arntl and Clock expression, but increased Per2. Additionally, it upregulated the expression of lipogenic genes such as Scd1, Elovl6, and Elovl3 and simultaneously downregulated fatty acid oxidation genes such as Cyp4a10, Cyp4a14, and Acot1, bringing about imbalance in lipid homeostasis. In addition, α-TE deficiency greatly changed the structure and composition of gut microbiota. Bacterial genera like Alistipes, norank_f__Muribaculaceae, Muribaculum, Odoribacter, and Dubosiella were significantly correlated with hepatic circadian and lipid metabolism gene expression with the strongest correlation being Alistipes. Conclusions This work is the first to reveal that short term α-TE deficiency could cause lipid metabolic disorder via the \"gut microbiota-liver circadian clock\" axis, which provides novel insights into the etiology of nutrition-related metabolic diseases and targets for nutritional intervention.","42356391":"ID: 42356391\nTitle: Ketogenic Diet in Obesity and Diabetes: A Narrative Review.\nAbstract: A ketogenic diet (KD) is a low-carbohydrate, high-fat dietary approach. Beyond treating neurologic disorders, KDs have attracted significant media attention for their potential to improve obesity and diabetes. The diet induces a metabolic shift from glucose toward fatty acid oxidation and ketone body production. This shift leads to ketosis, which may reduce hunger, partly through the anorexigenic effects of ketone bodies, thereby contributing to weight loss and improved metabolic parameters, including glycaemic control and insulin sensitivity. In particular, the positive effects of KDs lower insulin demand and may thereby improve β-cell function. However, the long-term efficacy, safety, and sustainability of KDs, especially for diabetes, remain debated. This review offers current insights into the effects of ketogenesis and ketosis, as well as the potential mechanisms underlying them. We explore the metabolic effects of KDs in obesity and diabetes, drawing on preclinical and clinical studies, and suggest that combining KDs with antidiabetic agents may provide synergistic benefits. However, combining KDs with these pharmacotherapies, particularly SGLT-2 inhibitors, requires careful clinical supervision because of potential risks, including euglycaemic diabetic ketoacidosis. We explore how a KD alters the composition of the gut microbiota, thereby affecting host health. We conclude by highlighting challenges and future directions for optimising KD-based therapies and by outlining the limitations of the current review.","42356415":"ID: 42356415\nTitle: Marine Peptides from Solenocera crassicornis Are Associated with Improved Metabolic, Hepatic, and Intestinal Markers During Diet Normalization in HFD-Induced Obese Mice.\nAbstract: Background/Objectives: Obesity-associated metabolic dysfunction involves oxidative stress, gut barrier impairment, and gut-liver axis disruption. This study evaluated whether enzymatically prepared Solenocera crassicornis peptides (SCPs) provide additional benefits during diet normalization in HFD-induced obese mice and examined associations with antioxidant, microbial, and barrier markers. Methods: SCPs were characterized using UPLC-Q-TOF-MS/MS and amino acid analysis. Peptides underwent bioactivity prediction and Keap1 docking. After 7 weeks of HFD feeding, obese male C57BL/6J mice were switched to a normal diet and administered vehicle, orlistat, or SCPs for 4 weeks. Adipose tissue mass, serum lipid profiles, liver histology, hepatic antioxidant status, barrier-associated histological and biochemical markers, and gut microbiota composition were assessed. A simulated digestion-fecal fermentation model was used to assess the effects of fermentation products generated in the presence of digested SCPs on H2O2-induced oxidative injury and MUC2 secretion in LS174T goblet-like cells. Results: SCPs reduced epididymal and perirenal fat, improved serum lipids, improved hepatic steatosis-related morphology and enhanced hepatic antioxidant status. SCPs were also associated with improved intestinal morphology, increased mucin-associated staining, decreased serum diamine oxidase levels and reduced hepatic lipopolysaccharide accumulation. 16S rRNA sequencing showed SCP-associated microbial shifts, with correlations linking taxa to metabolic and barrier markers. Fermentation products generated in the presence of digested SCPs improved oxidative-stress and MUC2-related readouts in LS174T cells. Conclusions: During diet normalization, SCPs were associated with additional improvements in adiposity, lipid profiles, hepatic antioxidant status, intestinal barrier readouts, and gut microbiota. These findings support further investigation of SCPs as standardized marine protein hydrolysates, but active components, causal mechanisms, long-term efficacy, safety, and human relevance remain to be established.","42357514":"ID: 42357514\nTitle: Exploring Active Ingredients and Mechanisms of Crataegi fructus Extract in Alleviating MAFLD via the AMPK/PPAR Pathway by Multi-Omics.\nAbstract: The fruit of Crataegi fructus (CF) is a traditional \"medicine food\" herb widely used for its lipid-lowering properties, but its active ingredients and mechanisms against metabolic dysfunction-associated fatty liver disease (MAFLD) remain poorly understood. This study employed an integrated multi-omics approach, combining serum metabolomics, liver transcriptomics, weighted gene co-expression network analysis (WGCNA), network pharmacology, and molecular docking, to systematically investigate the effects of CF extract (CFE) in a high-fat diet (HFD)-induced mouse model of MAFLD. Our analysis revealed that CFE treatment significantly reduced body weight gain (p < 0.01), improved glucose tolerance and insulin sensitivity (p < 0.01), and alleviated hepatic steatosis, as evidenced by reduced lipid accumulation and decreased NAS scores (p < 0.001). Metabolomics analysis showed that CFE reversed HFD-induced disturbances in serum fatty acids, glycerophospholipids, and bile acid metabolites. Transcriptomics further revealed that the AMPK and PPAR signalling pathways were critically involved in the regulation of lipid metabolism by which CFE alleviated MAFLD. Consistently, CFE treatment resulted in significant upregulation of AMPK and PPARα expression (p < 0.001) and downregulation of CD36 and DPP4 (p < 0.001), as confirmed by Western blotting and qPCR. Furthermore, integration of WGCNA and network pharmacology pinpointed chlorogenic acid (CA), ursolic acid (UA), and oleanolic acid (OA) as the primary bioactive components, and their lipid-lowering effects were validated in FFA-treated THLE-2 cells. In conclusion, this study offers preliminary insights into the lipid-lowering mechanisms of CFE via regulation of the AMPK/PPARα/CD36/DPP4 signalling pathway and support its further development as a functional food ingredient for MAFLD prevention.","42358145":"ID: 42358145\nTitle: [Research progress on the mechanism of hyodeoxycholic acid in the treatment of MASLD through the gut-liver axis].\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a metabolic liver disorder affecting over 30% of the global adult population, with its prevalence and mortality rates continuing to rise. Hyodeoxycholic acid (HDCA), a natural secondary hydrophilic bile acid and the primary active component of traditional Chinese medicine Sus scrofa gallbladder powder, has been demonstrated by multiple studies to ameliorate MASLD and other hepatic metabolic disorders, potentially exhibiting superior efficacy to metformin. This review systematically discusses the multifaceted regulatory mechanisms of HDCA on glucose metabolism, lipid metabolism, and inflammatory responses in the gut-liver axis and peripheral tissues through its interactions with bile acid receptors including farnesoid X receptor (FXR), Takeda G protein-coupled receptor-5 (TGR5), liver X receptor (LXR) and with gut microbiota. The paper aims to provide theoretical foundations and therapeutic targets for the safe treatment of MASLD and metabolic dysfunction-associated steatohepatitis (MASH).","42358148":"ID: 42358148\nTitle: [Research progress on the role of the microbiota-gut-liver axis immune pathway in metabolic dysfunction-associated steatotic liver disease].\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a widely prevalent chronic liver disease that presents significant challenges to public health and medical care worldwide, yet its underlying mechanisms remain incompletely understood. The gut microbiome plays a crucial role in MASLD. Liver inflammation is a key factor in the onset and progression of this disease, and the gut microbiota significantly influences the liver's immune system and inflammatory responses.

However, no systematic review has been conducted on the research progress and mechanisms of EGCG in relation to digestive system diseases, an its toxicity. We conducted a comprehensive literature search for preclinical studies from the inception of each database to 28th September 2025, including Embase, PubMed, Web of Science, China National Knowledge Infrastructure and Veipu Information. These studies were manually screened based on predefined criteria. A comprehensive literature review and meta-analysis were then performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A total of 74 animal studies were initially included. Following screening, 63 studies (involving 738 animals) met the inclusion criteria for the meta-analysis. EGCG's animal experiments in digestive system diseases primarily focus on tongue squamous cancer, colorectal cancer, liver cancer, ulcerative colitis, gastric cancer, and functional gastrointestinal disorders. EGCG also has positive effects on pancreatic cancer, radiation enteritis, hepatitis B, oral cancer, esophageal cancer, radiation-induced esophagitis, hepatitis C, acute pancreatitis, fatty liver, and cancer prevention. The potential common pathways include VEGF, EGFR, Notch, Bax/Caspase, Nrf2/UGTIA10, JAK/STAT, NF-κB, IGF/IGF-IR, Caspase-1, HIF-1α/VEGF, TGFβ/p-ERK/p-Smad1/2 and M1/M2 cell polarization. EGCG suppresses cell proliferation through the induction of apoptosis; however, its underlying mechanisms warrant further investigation. Administration of high-dose EGCG alone can induce hepatotoxicity, an effect that is exacerbated under inflammatory conditions. In the context of diabetes, EGCG may also lead to nephrotoxicity. It should be noted that these toxic doses substantially exceed the levels typically attained through normal dietary consumption of tea. The mechanisms responsible for EGCG-mediated toxicity remain to be fully elucidated. In vivo studies have indicated the potential efficacy of EGCG in managing gastrointestinal diseases. However, further investigations are necessary to validate its therapeutic benefits, elucidate the underlying mechanisms, and assess its potential toxicity.","42364524":"ID: 42364524\nTitle: Gut microbiota dysbiosis in chronic liver disease: Mechanisms driving hepatocellular carcinoma progression and therapeutic implications of Chinese medicine.\nAbstract: Chronic liver disease represents a major global public health challenge, and its malignant progression to hepatocellular carcinoma is the leading cause of death among affected patients. Gut microbiota dysbiosis is a critical driver of this process. As the central hub of the \"gut-liver axis,\" the gut microbiota, when disrupted, compromises the integrity of the intestinal mucosal barrier, promoting the translocation of microbial metabolites, such as lipopolysaccharides and aberrant secondary bile acids, to the liver. In turn, key signaling pathways become activated, including TLR4/NF-κB, Wnt/β-catenin, and PI3K/Akt, sustaining persistent hepatic inflammation and oxidative stress. These pathological processes accelerate the progression from liver fibrosis to cirrhosis, promote genomic instability, and suppress tumor suppressor gene expression, paving the way for the malignant transformation of hepatocytes. Leveraging its holistic regulatory properties, characterized by multi-component, multi-target, and multi-pathway actions, Chinese medicine can intervene at multiple stages of this inflammation-to-cancer cascade by modulating both the structure and function of the gut microbiota. It does so first by enriching beneficial short-chain fatty acid-producing bacteria, such as Lactobacillus and members of the phylum Firmicutes, which helps restore the intestinal mucosal barrier, limit endotoxin translocation, and alleviate hepatic inflammation and fibrosis. In parallel, by normalizing bile acid metabolism and reestablishing gut microbial homeostasis, Chinese medicine counteracts the development of a tumor-permissive microenvironment marked by immune suppression and DNA damage in hepatocytes induced by microbial metabolites. At the same time, it enhances anti-tumor immune responses mediated by CD8+ T cells and other immune effectors. Drawing on evidence from multi-omics analyses and clinical studies, this review examines the core mechanisms and recent advances regarding how Chinese medicine monomers and formulations modulate the gut microbiota to impede the progression of chronic liver disease to HCC. It highlights gut microbiota dysbiosis as a key driver of hepatocarcinogenesis and highlights the therapeutic potential of targeted microbiota regulation by Chinese medicine, providing a conceptual foundation and strategic approaches for the precision prevention and treatment of hepatocellular carcinoma.","42365696":"ID: 42365696\nTitle: Apigenin ameliorates methionine-choline deficient diet-induced metabolic-associated fatty liver disease through modulation of gut microbiota-liver axis.\nAbstract: Apigenin, a naturally occurring flavone widely present in the plant kingdom, possesses antioxidant, anti-inflammatory, and metabolic regulatory activities. Metabolic-associated fatty liver disease (MAFLD), a chronic liver disorder driven by metabolic stress, currently lacks effective pharmacological therapies. Given these pharmacological properties, apigenin may represent a promising candidate for MAFLD intervention. This study aimed to evaluate the therapeutic potential of apigenin in MAFLD and to elucidate the underlying mechanisms linking the gut microbiota and host lipid metabolism. A methionine-choline deficient (MCD) diet-induced mouse model of MAFLD, combined with lipidomic profiling, microbiota analysis, and metabolite assessment, was used to determine the beneficial effects of apigenin. Apigenin markedly ameliorated hepatic steatosis in MCD-fed mice, as demonstrated by reduced hepatic triglyceride accumulation, improved liver function markers, and alleviated hepatic inflammation and oxidative stress. Lipidomic profiling showed decreased hepatic saturated and polyunsaturated fatty acids accompanied by an increase in monounsaturated fatty acids and their related lipid species. Apigenin remodeled the gut microbiota, characterized by increased Lactobacillus abundance and decreased Akkermansia abundance. Further analyses identified homocysteine (HCY) as a key microbiota-associated metabolite that induced oxidative stress and reproduced the lipid dysregulation observed in MAFLD, thereby linking microbial alterations to hepatic lipid metabolism. These findings demonstrate that apigenin alleviates MAFLD by remodeling the gut microbiota-metabolite network, lowering HCY levels, and subsequently improving hepatic function, lipid metabolism, and oxidative stress, highlighting its potential as a phytochemical-based therapeutic strategy.","42368343":"ID: 42368343\nTitle: Dietary supplementation with walnut (Juglans regia L.) green husk polyphenol extract mitigates fatty liver hemorrhagic syndrome in laying hens.\nAbstract: Extracts derived from the walnut (Juglans regia L.) green husk exhibit a variety of biological activities. This study investigated the effects of walnut green husk polyphenol extracts (WGHPE) on fatty liver hemorrhagic syndrome (FLHS)-related indicators, antioxidant performance, and cecal microbiota modulation in laying hens. A total of 350 Hy-Line Brown laying hens aged 43 weeks were randomly assigned to five groups with seven replicates per group and 10 hens per replicate. An FLHS model was induced via intramuscular injection of β-estradiol dissolved in corn oil. The control (Con) and FLHS model groups received a basal diet, whereas three FLHS-based treatment groups were fed the basal diet supplemented with 0.5% (WGHPEL), 1.0% (WGHPEM), or 1.5% (WGHPEH) WGHPE, respectively. All laying hens had unrestricted access to food and water throughout the 8-week experimental period. Compared with the FLHS group, dietary supplementation with WGHPE significantly reduced liver weight, liver coefficient, abdominal adipose weight, and abdominal adipose coefficient. Histological evaluation demonstrated that WGHPE alleviated hepatocellular vacuolar degeneration and lipid droplet accumulation, indicating an improvement in FLHS-related pathological features. Furthermore, WGHPE significantly reversed FLHS-induced elevations in serum levels of total cholesterol, aspartate aminotransferase, alanine aminotransferase, and low-density lipoprotein cholesterol. WGHPE also enhanced systemic antioxidant capacity by increasing catalase and total superoxide dismutase activities in β-estradiol/corn oil-induced laying hens, while decreasing malondialdehyde levels. Regarding intestinal health, WGHPE significantly increased villus height and the villus-to-crypt ratio in the jejunum and ileum. Furthermore, in the WGHPE treatment group, the relative abundance of beneficial bacterial taxa was increased. Campylobacter and Parasutterella were positively correlated with body weight and abdominal adipose deposition, whereas Desulfovibrio and unclassified_Oscillospiraceae showed negative correlations. These findings collectively indicate beneficial associations between dietary WGHPE supplementation, intestinal microbiota composition, and overall health status in laying hens with FLHS. Dietary supplementation with WGHPE mitigated β-estradiol/corn oil-induced FLHS-associated liver injury, enhanced antioxidant capacity, and improved intestinal morphology and microbial composition. A supplementation level of 1.5% WGHPE is recommended for optimal efficacy.","42368425":"ID: 42368425\nTitle: Ceramide-mediated mitochondrial dysfunction in nonobese nonalcoholic fatty liver disease: A regulatory role for serine palmitoyltransferase subunit 2.\nAbstract: This study investigated the pathological relevance of the serine palmitoyltransferase long chain base subunit 2 (Sptlc2)-ceramide axis in nonobese nonalcoholic fatty liver disease (NAFLD), focusing on hepatic steatosis, inflammation, oxidative stress, and mitochondrial dysfunction. A nonobese NAFLD rat model was established using a high-temperature dry-fried soybean diet. Integrated liquid chromatography-mass spectrometry-based proteomic and metabolomic analyses were used to identify candidate pathways. Sptlc2 function was validated by AAV2/8-mediated liver-directed knockdown in vivo, lentiviral knockdown in primary hepatocytes, and C2-ceramide rescue experiments. Multi-omics profiling identified Sptlc2 as a sphingolipid metabolism-related candidate in the model. Sptlc2 knockdown reduced long-chain ceramide accumulation, hepatic lipid deposition, inflammatory cytokine expression, oxidative stress, and hepatocyte injury. In primary hepatocytes, Sptlc2 silencing improved mitochondrial respiration, membrane potential, calcium and reactive oxygen species homeostasis, and mitochondrial ultrastructure. These protective effects were partially reversed by C2-ceramide in vitro and in vivo. The Sptlc2-ceramide axis contributes to ceramide accumulation, hepatic lipotoxicity, inflammatory activation, and mitochondrial dysfunction in this nonobese NAFLD model, suggesting its potential relevance as a therapeutic target for further investigation.","42371165":"ID: 42371165\nTitle: The microbiota-mitochondria axis: linking metabolic dysfunction to neurodegeneration.\nAbstract: The interplay between gut microbiota and mitochondria represents a dynamic relationship that profoundly impacts host physiology, ranging from maintaining intestinal homeostasis to regulating systemic metabolic and neurological functions. Microbial metabolites such as short-chain-fatty-acids, bile acids, and amino acid derivatives serve as pivotal modulators of mitochondrial bioenergetics, oxidative stress management, and fission-fusion processes. These interactions are vital for preserving epithelial integrity, supporting energy metabolism, shaping immune responses, and managing inflammatory signaling pathways. Disruptions within this microbiota-mitochondria axis are associated with various pathologies, including non-alcoholic fatty liver disease, obesity, type 2 diabetes, and chronic inflammatory conditions like inflammatory bowel disease. Additionally, growing evidence connects gut dysbiosis and mitochondrial dysfunction to neurodegenerative disorders such as Parkinson's disease and Alzheimer's disease, highlighting the importance of this bidirectional relationship in maintaining neuronal health. On a mechanistic level, pathways involving AMPK, sirtuins, and PGC-1α govern mitochondrial biogenesis and adaptive responses to microbial signals. Dysregulation of these pathways can heighten oxidative stress, hinder mitophagy, and contribute to systemic inflammation. Emerging therapeutic strategies aim to target this axis through dietary modifications, probiotics and engineered microbes, FMT, and mitochondria-specific pharmacological treatments. These interventions focus on restoring metabolic stability, enhance resilience against oxidative damage, and slowing disease progression. By integrating insights from fields such as metabolism, immunology, and neuroscience, this review positions the microbiota-mitochondria axis as a critical area of focus in biomedical research. A deeper understanding of this communication network offers promising opportunities for precision therapies aimed at addressing metabolic, inflammatory, and neurodegenerative diseases.","42374202":"ID: 42374202\nTitle: Bioactive folate attenuates valproic acid-induced NAFLD in female rats.\nAbstract: Nonalcoholic fatty liver disease (NAFLD) is a key contributor to chronic liver diseases. It is defined as hepatic fat accumulation in ≥ 5% of hepatocytes in individuals with minimal or no alcohol consumption and no other identifiable causes of liver steatosis. Drug-induced hepatic toxicity is increasingly recognized as a key contributor to the development and progression of NAFLD. Among them, valproic acid (VPA), an antiepileptic drug, is well documented for inducing hepatic steatosis, in addition to interfering with folate metabolism and accelerating the progression of NAFLD. The current study distinctively evaluates the protective role of bioactive folate derivatives (folinic acid and 5-methyltetrahydrofolate) in a VPA-induced NAFLD rat model. Adult female Sprague Dawley rats were divided into three groups: control, diseased and treated. Liver function test, histopathological examination, gene expression analysis, and molecular docking were performed. Liver function tests indicated that the increase in alanine aminotransferase, alkaline phosphatase, and total bilirubin levels was highly significant in the diseased group, indicative of hepatic injury. Histopathological examination demonstrated severe steatosis in VPA-treated animals, which was significantly improved in the folate-treated group. The NAFLD Activity Score, a mild NAFLD was observed in the diseased group with a total score of 2. Gene expression studies showed high upregulation of HO-1 and pro-inflammatory cytokines TNF-α and IL-6 in the diseased group, whereas downregulation was observed in folate-treated rats. Furthermore, molecular docking studies indicated that folinic acid and 5mTHF showed high affinities for binding to KEAP1 protein, suggestive of activation of the Nrf2-KEAP1 antioxidant pathway. Collectively, our data provide significant evidence for the protective potential of bioactive folate supplementation in the amelioration of the VPA-induced liver injury through modulation of oxidative stress, inflammation, and lipid accumulation.","42377574":"ID: 42377574\nTitle: Butyrate ameliorates maternal high-fat-diet-induced placental inflammation and offspring metabolic dysfunction via modulating gut microbiota in mice.\nAbstract: Maternal high-fat diet (HFD) increases the risk of metabolic disorders in offspring. Placental inflammation acts as a critical mediator with poorly addressed etiology. Recently HFD-induced gut dysbiosis is demonstrated to be a key driver of systemic inflammation. Whether inflammatory signals triggered by HFD-induced gut dysbiosis are transmitted to the placenta via the maternal-fetal axis warrant further investigation. This study aims to elucidate the mechanistic connection between maternal gut dysbiosis and placental inflammation, thereby offering insights into microbiota-mediated developmental origins of metabolic diseases in offspring. Female C57BL/6 mice were exposed to high fat diet (HFD) for 5 weeks prior to mating with male mice. Gut microbiota was profiled by using 16 S rRNA sequencing and fecal short-chain fatty acids (SCFAs) were quantified by GC-MS from HFD pregnant mice at gestational day 18.5 (G18.5). Mice were sacrificed at G18.5, and placenta histopathological analysis as well as inflammatory markers and lipopolysaccharide (LPS) level were analyzed. Anti-inflammatory effects of butyrate were evaluated in vitro by using HTR-8/Svneo cells and in vivo through gestational supplementation (0.3 mg/g body weight) in HFD-fed dams. Maternal HFD exposure induced significant placental inflammation as well as hepatic steatosis in the offspring. HFD-fed dams exhibited distinct gut dysbiosis with reduced fecal and serum SCFAs, which was accompanied by elevated placental LPS levels and exacerbated inflammatory responses. Butyrate treatment suppressed the expression of inflammatory cytokines in vitro through down-regulating the phosphorylation of NF-κB, ERK1/2 signaling pathways via G-protein-coupled receptor 41 (GPR41). Furthermore, gestational butyrate intervention effectively alleviated placental inflammation and mitigated fetal hepatic lipid deposition in HFD-exposed offspring. Placental inflammation caused by maternal HFD is closely associated with gut microbiota dysbiosis. Butyrate supplementation during gestation reduces placental inflammation and ameliorated offspring hepatic steatosis, highlighting the therapeutic potential of butyrate for mitigating the adverse metabolic programming effects upon maternal HFD exposure.","42381129":"ID: 42381129\nTitle: Pharmacological Targeting of NRF2 Represents a Promising Therapeutic Approach for Pyroptosis-Related Non-Alcoholic Fatty Liver Disease.\nAbstract: Non-alcoholic fatty liver disease (NAFLD) is a clinicopathological condition characterized by the accumulation of fat within hepatocytes in the absence of excessive alcohol consumption or other identifiable causes of liver injury. As a disease involving complex pathogenic mechanisms, NAFLD has become the most prevalent chronic liver disease and may progress to more severe conditions. Pyroptosis is a pro-inflammatory form of programmed cell death that is distinct from classical apoptosis. Accumulating evidence suggests that pyroptosis plays a role in the pathogenesis of NAFLD, contributing to disease progression from simple hepatic steatosis to non-alcoholic steatohepatitis (NASH) and fibrosis. Excessive activation of pyroptosis can exacerbate inflammatory responses, induce cellular damage, disrupt immune homeostasis, and impair liver function. Therefore, elucidating the mechanisms and roles of pyroptosis in NAFLD is crucial for the development of effective therapeutic strategies. As a key transcription factor, nuclear factor erythroid 2-related factor 2 (NRF2) has emerged as a promising therapeutic target. Pharmacological modulation of NRF2 has shown potential in treating diseases characterized by oxidative stress and inflammation. Findings from in vitro and animal studies suggest that various compounds that target NRF2 to modulate pyroptosis exhibit notable effects on the initiation and progression of NAFLD. Although most of these agents are still in the early stages of preclinical research, they hold substantial promise for future clinical translation. This review outlines recent advances in pyroptosis-related research in NAFLD and highlights pharmacological targeting of NRF2 as a promising therapeutic approach for pyroptosis-mediated NAFLD.","42382178":"ID: 42382178\nTitle: Mangiferin alleviates metabolic-associated fatty liver disease by modulating gut microbiota and FXR signaling pathway to regulate bile acid metabolism.\nAbstract: Metabolic-associated fatty liver disease (MAFLD) is characterized by excessive hepatic lipid accumulation, with limited safe and effective therapeutic options currently available. Previous studies have demonstrated that mangiferin (MAN) alleviates nonalcoholic fatty liver disease via modulation of the AMPK and NLRP3 signaling pathways. However, there are no reports to date investigating whether MAN exerts anti-MAFLD effects by regulating bile acid (BAs) metabolism and its underlying molecular mechanisms. In the present study, the anti-MAFLD effects of MAN were systematically investigated using a high-fat diet (HFD)-induced MAFLD mouse model. We evaluated the therapeutic mechanisms of MAN specifically from the perspectives of BAs metabolism regulated by the farnesoid X receptor (FXR) signaling pathway and the modulation of the gut microbiota, utilizing 16S rRNA sequencing and molecular docking analyses. MAN treatment (100 mg/kg) significantly ameliorated glucose and lipid metabolic disorders, as well as hepatic lipid accumulation in the HFD-induced MAFLD mice, which was accompanied by marked alterations in the BAs metabolic profile. Mechanistically, MAN activated the FXR signaling pathway, and molecular docking analysis predicted stable interactions with key FXR residues (Y365, M369, and Y373). Furthermore, 16S rRNA sequencing revealed that MAN significantly decreased the relative abundance of Lactobacillus and Limosilactobacillus, which were positively correlated with abnormal BAs (including 6,7-DKLCA, ILCA, GHDCA, and GUDCA), dyslipidemia, and liver injury markers. In contrast, MAN increased the relative abundance of Faecalibaculum, which was negatively correlated with these BAs and associated with an improved metabolic status. MAN exerts anti-MAFLD effects through dual mechanisms: direct activation of the FXR signaling pathway to regulate BAs homeostasis and indirect modulation of the gut microbiota to influence BAs metabolism. These findings highlight the therapeutic potential of MAN and provide new insights into natural product-based strategies for MAFLD treatment.","42382779":"ID: 42382779\nTitle: Nurr1 deficiency orchestrates a coupled liver-gut pathological axis revealed by multi-omics and deep-learning histopathology.\nAbstract: The nuclear receptor Nurr1 (NR4A2) is a transcriptional regulator of inflammatory homeostasis, but its systemic effects on orchestrating inter-organ communications are largely unknown. Here we show that Nurr1 haplo-insufficiency results in a lethal coupled disorder across the liver-gut axis. Using a CRISPR-Cas9 generated murine model, we find that metabolically-activated heterozygous deficiency of Nurr1 results in profound hepatocellular necrosis and marked hepatic activation of inflammatory and pro-fibrotic genes coupled with dysregulation of the intestinal barrier, and severe small-intestinal dysbiosis. Multi-omics integration reveals a highly penetrant transcriptional signature of this herein termed liver-gut disorder, achieving up to 0.950 accuracy (SVM-RBF, 10-fold cross-validation) in classifying genotypes from integrated multi-omics features. Notably, we also demonstrate that these gene level perturbations in Nurr1 haplo-insufficiency can be thought of as learnable tissue 'morphologies' detectable by AI. Next, we created deep convolutional neural networks that accurately classify genotype from routine histopathology. Our algorithm achieves 99.50% accuracy in classifying hepatic fibrosis (Sirius Red), 99.20% in liver inflammation (H&E) and 92.31% in intestine (H&E). We provide the first multi-omics phenotype of Nurr1 deficiency, revealing its pivotal regulatory role in coordinating liver-gut homeostasis, and establishing a histopathological AI-driven framework. Grad-CAM saliency analysis confirms biological interpretability.

Accumulating evidence demonstrates that dysregulated copper handling, including deficiency, redistribution, or overload, is a reproducible feature of multiple cardiometabolic disorders, including heart failure, diabetes mellitus, obesity, and NAFLD/MASLD. Human, animal, and cellular studies consistently implicate altered copper trafficking and compartmentalization in mitochondrial dysfunction, oxidative stress, and tissue remodeling across these conditions. The recent identification of cuproptosis, a copper-dependent form of regulated cell death characterized by mitochondrial copper binding to lipoylated tricarboxylic acid cycle enzymes, has expanded mechanistic understanding of copper toxicity in cancer. However, the defining molecular hallmarks of canonical cuproptosis, including lipoylated protein aggregation, iron-sulfur cluster loss, and respiration-dependent cell death, have not yet been demonstrated in vivo in cardiometabolic tissues. Accordingly, cuproptosis is discussed here as a testable mechanistic hypothesis rather than an established driver of cardiometabolic pathology. In this review, we synthesize current evidence for copper dysregulation in cardiometabolic disease and carefully distinguish established copper-dependent pathology from speculative cuproptotic mechanisms. We explicitly address the apparent paradox that the cardiac tissue context in cardiometabolic disease is dominated by a copper-deficient phenotype, which is the opposite of the mitochondrial copper-loading state required for canonical cuproptosis, and reconcile this through the concept of intracellular copper redistribution and tissue-selective susceptibility. We evaluate clinical and preclinical studies of copper-modulating therapies with attention to tissue specificity and safety, and we outline a framework for rigorously testing cuproptosis in vivo using convergent molecular, functional, and clinical criteria. Together, this review clarifies what is known about copper biology in metabolic disease and defines the experimental standards required to determine whether cuproptosis contributes to these conditions.","42384365":"ID: 42384365\nTitle: Toll-like Receptor 4 Knockout Mice are Protected Against PMOS-like Pathogenesis.\nAbstract: Polyendocrine metabolic ovarian syndrome (PMOS), formerly termed polycystic ovary syndrome (PCOS), is a reproductive disorder with heterogeneous symptoms and severity. Despite extensive research documenting chronic immune dysfunction as a hallmark of PMOS, the specific mechanisms of immune activation remain poorly understood. Emerging evidence suggests that gut-derived bacterial endotoxins, particularly lipopolysaccharide (LPS), can breach intestinal barriers and trigger systemic inflammation via Toll-like receptor 4 (TLR4). This study examined the role of TLR4 in PMOS-like pathology using a letrozole (LET)-induced mouse model. In LET-treated wild-type female mice, serum LPS and its carrier protein LBP were elevated compared to LET-treated TLR4-/- mice. Additionally, TLR4 deficiency attenuated multiple PMOS-like features, including elevated luteinizing hormone, anovulation, and metabolic dysfunction. LET-treated TLR4-/- mice also preserved estrous cycling and fertility, maintained gut barrier integrity, and reduced inflammatory markers. These findings support TLR4 as an important contributor to multiple features of PMOS-like pathology. This novel work highlights TLR4-mediated inflammation as a potential target for anti-inflammatory treatments in women with PMOS.","42385432":"ID: 42385432\nTitle: Polyphenols extracted from Lycium barbarum seeds regulate gut microbiota to improve type 2 diabetes mellitus in db/db mice.\nAbstract: Mounting evidence positions the gut microbiota as a pivotal player in the onset and progression of type 2 diabetes mellitus (T2DM). Lycium barbarum seed polyphenols (LBSPs), a byproduct of Lycium barbarum processing, have shown antioxidant and anti-inflammatory bioactivities, but potential anti-T2DM effects remain unclear. To evaluate the preventive effects of LBSPs against T2DM and the associated gut microbiota mechanisms. The effects of LBSPs on fasting blood glucose, insulin sensitivity, liver lipid accumulation, intestinal barrier, gut microbiota composition, and microbial metabolites were investigated in db/db mice. LBSPs significantly reduced fasting blood glucose, improved insulin sensitivity, and alleviated dyslipidemia and hepatic steatosis in db/db mice. Furthermore, LBSPs restored intestinal barrier integrity by up-regulating tight junction proteins Claudin-1, Occludin, and Zonula Occludens-1 (ZO-1). 16S rRNA analysis revealed that LBSPs reversed gut microbiota dysbiosis, enriching Lactobacillus, Ligilactobacillus, Rikenella, Lachnospiraceae_NK4A136_group, while decreasing Escherichia-Shigella and Klebsiella. Mechanically, LBSPs can modulate aromatic amino acid metabolism, lipid metabolism, and bile acid biosynthesis by metabolomics. Mediation analysis indicated that specific gut microbiota influenced host metabolic parameters through metabolites such as 7-megastigmene-3,6,9-triol 9-glucoside. Our findings reveal that LBSPs can be used as a potential microbiota-targeted nutraceutical that reverses gut microbiota dysbiosis and diabetes-associated metabolic disorders during T2DM progression.","42385626":"ID: 42385626\nTitle: More efficient and precise toward application of tomato-derived lycopene: a state-of-the-art review into sources, chemistry, extraction methods, bioavailability, and uniting power in fatty liver disease.\nAbstract: Fatty liver disease (FLD) is among the most prevalent chronic liver disorders worldwide. Tomato-derived lycopene has received considerable attention as a functional bioactive compound due to its strong antioxidant and anti-inflammatory effects on molecular pathways associated with FLD progression. Nevertheless, an integrated assessment of lycopene sources, chemistry, extraction technologies, stability, and functional efficacy remains limited. Lycopene bioavailability is restricted by its lipophilic nature and instability during food processing and gastrointestinal digestion. Degradation pathways including photo-oxidation, thermal trans-cis isomerization, and oxidative cleavage are intensified during high-temperature drying (>70 °C), prolonged storage, light exposure, and oxygen-rich processing conditions, resulting in reduced stability and biological activity. Advanced emerging delivery systems such as nanoencapsulation, nanoemulsions, and lipid-based carriers have shown promising improvements in lycopene protection, absorption, and efficacy. Future approaches including biofortification, personalized nutrition, and synergistic formulations may support the development of innovative functional foods for FLD prevention and management.","42385714":"ID: 42385714\nTitle: Gut commensal Bacteroides-derived pantothenic acid alleviates metabolic syndrome.\nAbstract: Pantothenic acid (PA), or vitamin B5, can be synthesized by gut commensals, but the contribution of microbial PA to metabolic health remains unclear. Here, we find that microbial PA supply is reduced in individuals with metabolic syndrome (MetS) and is associated with impaired gut barrier function and disease severity. Tracing microbial PA identifies Bacteroides fragilis as a key contributor, with panC required for PA biosynthesis, as confirmed by isotope tracing, bacterial culture, and germ-free colonization. In MetS models, colonization with wild-type, but not ΔpanC B. fragilis, restores PA, preserves gut barrier integrity, reduces endotoxemia, and improves metabolic dysfunction. Mechanistically, microbial PA requires host pantothenate kinase activity, as silencing pantothenate kinase 2/3 (PANK2/3) in colonic organoids and in vivo reduces coenzyme A (CoA)/acetyl-CoA metabolism, suppresses Krüppel-like factor 4 (KLF4)-associated differentiation programs, and blunts the protective effects of microbial PA. Finally, a plant-derived polysaccharide enriches PA-producing Bacteroides and restores colonic PA, highlighting a strategy for colonic homeostasis and metabolic health.","42385885":"ID: 42385885\nTitle: Alcohol and high-fat diet aggravate colitis-induced liver injury via glucocorticoid/IL-6-SAA1 axis in mice.\nAbstract: Colitis-associated liver injury rarely causes acute mortality, but whether alcohol and a high-fat diet (HFD) aggravate hepatic injury during colitis remains unclear. Here, dextran sulfate sodium (DSS)-induced colitic mice were exposed to alcohol, HFD, or both. Compared with DSS alone, combined HFD and alcohol exposure (DSSHA) caused greater body-weight loss, poorer body condition, and reduced survival. These effects were linked mainly to liver rather than intestinal deterioration, as shown by an increased liver/body-weight ratio, elevated serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST), and severe hepatic steatosis, whereas colon length, colon weight, and intestinal histological injury were not further aggravated. Mechanistically, alcohol-HFD co-exposure impaired the gut-liver axis, reduced intestinal tight-junction proteins, increased gut permeability and circulating lipopolysaccharide (LPS), and promoted hepatic macrophage and neutrophil infiltration with increased interleukin-6 (IL-6). Transcriptomics identified serum amyloid A1 (SAA1) as a highly upregulated acute-phase gene and revealed Toll-like receptor 4 (TLR4) pathway enrichment. TLR4 inhibition TAK-242 significantly improved survival and attenuated liver injury. Multi-omics further showed increased hepatic cortisol and corticosterone, which cooperated with IL-6 to induce SAA1 expression in HepG2 cells. Thus, an IL-6/glucocorticoid-SAA1-TLR4 axis drives alcohol-HFD-aggravated liver injury in colitis and may represent a therapeutic target.","42387035":"ID: 42387035\nTitle: Tirzepatide as a multi-organ integrator in metabolic diseases: a review of molecular mechanisms and clinical translation.\nAbstract: Metabolic diseases, including type 2 diabetes mellitus (T2DM), obesity, dyslipidemia, Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD), and obstructive sleep apnoea (OSA), are characterized by a complex and interconnected pathophysiological syndrome. These conditions involve insulin resistance, chronic inflammation, and disturbances in energy homeostasis. Typically, they affect multiple organs and require comprehensive treatment. This narrative review examines the multi-organ effects of tirzepatide, a new dual agonist of the glucose-dependent insulinotropic peptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors. Tirzepatide possesses innovative therapeutic properties and targets multiple metabolic pathways. The review incorporates peer-reviewed sources, including clinical trials, preclinical studies, and specialist reviews. Emphasis is placed on tirzepatide's physiological effects on pancreatic β-cells, adipose tissue, the liver, the gastrointestinal tract, the cardiovascular system, the kidneys, the brain, and gut microbiota. Tirzepatide is a dual receptor agonist that increases insulin levels, decreases glucagon levels, slows gastric emptying, and promotes feelings of fullness, contributing to significant weight loss. Recent preclinical studies have shown that tirzepatide can also alter gut microbiota composition, leading to increased Bacteroidetes and decreased Firmicutes. Additionally, tirzepatide has been shown to enhance intestinal barrier integrity. Clinical trial programs, such as SURPASS and SURMOUNT, have demonstrated that tirzepatide provides improved glycemic control and weight loss compared to current treatments. Other benefits include improvements in lipid profiles, reduced hepatic steatosis, and potential protection for the heart and kidneys. Tirzepatide is a multi-organ integrator with a therapeutic effect extending beyond glucose regulation. It can influence bowel hormones, improve metabolic parameters, and facilitate communication between different organs, making it a promising treatment for metabolic disorders. However, its broader clinical applications need to be confirmed through additional real-life studies and extended evaluations.","42387267":"ID: 42387267\nTitle: Review Article: The Impact of the Gut Microbiome on Ulcerative Colitis Pharmacotherapy.\nAbstract: Ulcerative colitis (UC) is a chronic immune-mediated condition of the gastrointestinal tract with highly variable treatment responses. Current therapies focus on suppressing inflammation through aminosalicylates, corticosteroids, immunomodulators, biologics, and small molecules, yet many patients experience suboptimal outcomes, including non-response, partial response, or loss of efficacy over time. This variability has prompted increasing attention to the gut microbiome as a contributing factor. This review aimed to compile the current evidence on how the gut microbiome modulates the efficacy and pharmacokinetics of UC therapies, including mechanisms of microbial drug metabolism and host-microbe interactions that affect immune regulation. Clinical and preclinical studies exploring the role of the microbiome in UC pharmacotherapy were identified through targeted PubMed and Embase searches. Microbial communities in the gut alter UC drug exposure and action by metabolising active compounds, modifying the host immune response, and influencing local drug absorption and clearance. Differences in microbiome composition and function between individuals may explain some of the heterogeneity in drug response, durability and adverse effect profiles. Clinical studies now show that microbiome characteristics at baseline can correlate with UC treatment outcomes and may even predict therapeutic response. Understanding these microbiome-drug relationships may improve the precision of UC therapy, support the development of microbiome-guided interventions, and inform future drug development and clinical trial design. Recognising the microbiome as an active variable in treatment response reframes pharmacology in UC as not only drug- and host-dependent but also shaped by the dynamic microbial environment of the gut.","42388495":"ID: 42388495\nTitle: The impact of gut microbiome on intrahepatic cholestasis of pregnancy-systematic literature review.\nAbstract: In recent years, there has been a growing interest in the gut microbiome and its potential role in the etiopathogenesis of both gastrointestinal and extraintestinal diseases. Dysbiosis, characterized by a pathological alteration in the composition of the gut microbiome, has been implicated in various gastrointestinal diseases. This paradigm extends to pregnancy-specific conditions, including intrahepatic cholestasis of pregnancy (ICP). ICP exhibits a multifactorial etiopathogenesis, involving hormonal, genetic and environmental factors, among others. Despite growing scientific evidence, there is currently a lack of comprehensive reviews that specifically examine the causal mechanisms through which gut microbiota dysbiosis might contribute to the pathogenesis of ICP, as well as the resulting implications for the development of new targeted therapeutic approaches. Notably, shifts in microbial taxa and the depletion of bacteria involved in certain metabolic pathways have been observed in ICP. These findings suggest that alterations in the gut microbiome composition may contribute to the pathophysiology of ICP. Such microbiome-associated alterations may have important implications for risk stratification and early identification of patients at increased risk of adverse maternal and fetal outcomes. Further investigation into these microbial changes and molecular pathways could offer novel insights and identify potential pharmacological targets for ICP development and management. In particular, modulation of the gut microbiome could represent a future adjunctive strategy to existing therapeutic approaches, potentially improving disease monitoring and individualized management. The precise role of gut microbiome composition in the management and treatment of ICP is still not fully understood, highlighting the need for a systematic review to synthesize existing evidence and identify critical gaps relevant to the future development of screening, prevention, and targeted therapeutic strategies.","42388541":"ID: 42388541\nTitle: Multi-target Mechanisms and Clinical Evidence for Ganzaoning Granule in Metabolic Dysfunction-Associated Steatotic Liver Disease: A Narrative Review.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly discussed largely under the non-alcoholic fatty liver disease (NAFLD) framework, is now one of the most common chronic liver diseases worldwide. Its progression from simple steatosis to metabolic dysfunction-associated steatohepatitis (MASH), fibrosis, cirrhosis, and hepatocellular carcinoma (HCC) reflects the interaction of lipid overload, insulin resistance, oxidative stress, immune activation, hepatic stellate cell activation, and oncogenic remodeling. Although resmetirom and glucagon-like peptide-1 receptor agonist-based strategies have recently advanced the treatment landscape for selected patients with MASH and fibrosis, many patients remain outside the indications of current drug therapy, and safe adjunctive strategies across earlier disease stages remain an unmet need. Ganzaoning granule is a traditional Chinese medicine formulation derived from the anti-HCC precursor formula Ganfujian and has been used clinically in China for fatty liver disease and related chronic liver conditions. This narrative review summarizes the available evidence on Ganzaoning, including its phytochemical profile, network pharmacology findings, preclinical studies, and clinical observations in MASLD/NASH populations. Existing studies suggest that Ganzaoning or its related active fractions may modulate lipid metabolism through the AMP-activated protein kinase (AMPK)/peroxisome proliferator-activated receptor gamma coactivator-1 alpha (PGC-1α) axis, attenuate inflammatory signaling involving nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kB) and advanced glycation end-product (AGE)-receptor for advanced glycation end-product (RAGE) pathways, and influence fibrosis- and hepatocarcinogenesis-related molecular processes. However, much of the mechanistic evidence remains preclinical or inferred from network pharmacology, and the clinical evidence is limited by single-center designs, short follow-up, composite endpoints, and limited use of histological or advanced imaging outcomes. We therefore position Ganzaoning as a biologically plausible candidate adjunctive therapy rather than an established MASLD treatment. Future research should prioritize standardized product quality control, pharmacokinetic and pharmacodynamic characterization, herb-drug interaction assessment, and multicenter, double-blind, placebo-controlled trials using accepted MASLD endpoints.","42388647":"ID: 42388647\nTitle: Astaxanthin Vesicles Improve Alcoholic Liver Disease Through Oxidative Stress and NF-κB Inflammatory Pathway.\nAbstract: Liver injury induced by alcoholic fatty liver disease (ALD) will eventually lead to the development of hepatocellular carcinoma. The antioxidant and anti-inflammatory functions of astaxanthin (AST) can prevent and alleviate liver injury. In this study, AST was embedded in fatty acid vesicles to determine the effects of astaxanthin vesicles (AST-FAV) on ALD. The results demonstrated that compared to free AST, AST-FAV improved liver fat accumulation and oxidative damage caused by excessive drinking, and inhibited the production of pro-inflammatory cytokines by regulating the TLRs/MyD88/NF-κB, TNF-α/TNFR/NF-κB, and NLRP3/NF-κB pathways. In summary, AST-FAV can exert its anti-inflammatory effect through antioxidation and multiple pathways to prevent liver injury. These findings not only highlight the potential of AST-FAV for application in functional foods or dietary supplements but also provide a theoretical basis for further exploration of its potential as a clinical intervention strategy for the prevention or adjunctive treatment of alcoholic liver disease in humans.","42389066":"ID: 42389066\nTitle: Metabolic Dysfunction-Associated Fatty Liver Disease: From Pathogenesis to Treatment.\nAbstract: Metabolic dysfunction-associated fatty liver disease (MAFLD) has become the most prevalent chronic liver disease worldwide and represents a major hepatic manifestation of systemic metabolic dysfunction. The disease is closely linked to obesity and insulin resistance and progresses from simple hepatic steatosis to metabolic dysfunction-associated steatohepatitis, fibrosis, cirrhosis, and hepatocellular carcinoma. Increasing evidence indicates that MAFLD pathogenesis involves complex interactions among dysregulated lipid metabolism, mitochondrial dysfunction, oxidative stress, inflammatory signaling, bile acid imbalance, and gut microbiota-derived metabolites, reflecting the systemic and multifactorial nature of the disease. However, despite substantial progress in understanding these mechanisms, the integrated regulatory networks driving MAFLD progression and their translational therapeutic implications remain incompletely characterized. In this review, we comprehensively summarize recent advances in the molecular mechanisms underlying MAFLD, focusing on metabolic dysregulation, cellular stress responses, inflammatory pathways, and regulated cell death processes. We further highlight the critical role of interorgan communication particularly the adipose-liver and gut-liver axes and discuss emerging evidence on extracellular vesicles (EVs) as mediators of metabolic and inflammatory signaling. Finally, we evaluate current and potential therapeutic strategies, emphasizing the diagnostic and therapeutic promise of EV-based approaches in MAFLD management, and identifying emerging molecular targets for improved intervention and future clinical translation opportunities.","42389262":"ID: 42389262\nTitle: 2-Pentadecyl-2-oxazoline alleviates anxiety-like behaviour and modulates the microbiota-gut-brain axis in obese mice.\nAbstract: A bidirectional relationship between obesity and anxiety disorders has been increasingly associated with neuroinflammation and dysregulation of the gut-brain axis. Here, we investigated the pharmacological effects of the N-palmitoylethanolamine oxazoline derivative 2-pentadecyl-2-oxazoline (C15OXA) in a mouse model of high-fat diet (HFD)-induced obesity, with particular attention to its central and peripheral mechanisms of action. Male C57Bl/6J mice were fed an HFD for 12 weeks and subsequently treated with C15OXA (30 mg·kg-1, p. o.) for 7 weeks. Behavioural, molecular, and microbiota analyses were performed to evaluate the effects of the compound. C15OXA significantly reduced anxiety-like behaviour in obese mice without affecting body weight, fat mass, or glucose tolerance. At the central level, C15OXA attenuated hippocampal neuroinflammation, as shown by reduced expression of COX-2, TLR4, NLRP3 and IL-1β. In parallel, C15OXA restored tight junction gene expression associated with blood-brain barrier integrity, and modulated unfolded protein response signalling. In addition, C15OXA enhanced markers of neurogenesis and synaptic plasticity. At the peripheral level, C15OXA treatment reduced colonic inflammation and improved gut barrier integrity. These effects were associated with a targeted reshaping of gut microbiota composition. In particular, C15OXA promoted the enrichment of butyrate- and menaquinone-producing bacteria, as taxa linked to beneficial metabolic functions. Overall, these findings suggest that C15OXA exerts anxiolytic-like effects associated with coordinated central and peripheral pathways involving the modulation of neuroinflammatory pathways, barrier integrity, and gut-brain axis signalling. This study provides novel pharmacological insight into the therapeutic potential of C15OXA for the treatment of obesity-associated neuropsychiatric disorders.","42389671":"ID: 42389671\nTitle: Leveraging artificial intelligence for analysis of the gut microbiome for dementia diagnosis: a scoping review and discussion.\nAbstract: Dementia, a multifactorial disease with progressive cognitive decline, has been linked to imbalances in the gut-brain axis. Emerging artificial intelligence tools have augmented the identification of several gastrointestinal biomarkers for differential dementia detection and severity, but current literature lacks a comprehensive review. This study aims to better quantify the applications of AI in the exploration of the gut microbiome for diagnosis of specific subtypes of dementia. Primary articles (n = 896) from any point in time through July 2025 were identified from PubMed, Web of Science, Scopus, and ScienceDirect. Title and abstract screenings filtered articles from 896 to 28 for critical appraisal and review for key bacteria, fungi, and metabolites. Methods adhered to the PRISMA extension for Scoping Reviews (PRISMA-ScR) guidelines. Several studies utilized predictive models including random forests and neural networks to demonstrate alterations in the gut microbiota of Alzheimer's disease, an increasingly prevalent dementia subtype. These individuals have notably reduced levels of butyrate-producing bacteria, such as Butyrivibrio, Eubacterium, and Faecalibacterium, which contribute to anti-inflammation and gut-barrier maintenance. Increased levels of Odoribacter splanchnicus and Klebsiella pneumoniae, as well as bacteria from generas Bacteroides and Prevotella, which help generate short-chain fatty acids, have been implicated in neuroinflammation; Roseburia inulinivorans negatively correlates with functional ability. Interestingly, superagers also display unique microbiome profiles that seemingly have protective effects linked to superior cognitive resilience. Distinct gut microbial compositions are associated with dementia. Furthermore, elucidating gut-brain interactions and their neurodegenerative implications can identify targets for earlier, synergistic diagnostics. https://osf.io/yw2dc/overview.","42390972":"ID: 42390972\nTitle: Developmental maturation of intestinal junctional complexes in preterm infants.\nAbstract: Preterm infants are prone to gastrointestinal complications such as infectious diseases and necrotizing enterocolitis, which are associated with intestinal inflammation and increased intestinal permeability. Intestinal epithelial barrier (IEB) function is known to be immature in preterm neonates; however, our understanding of how the IEB develops - particularly the formation of junctional complexes - remains limited. Here, we analyzed intestinal tissue specimens from healthy resection margins of six very immature preterm infants who underwent bowel resection due to focal intestinal perforation (at the chronological age of 25 to 28 weeks' gestation), and compared the composition of tight junctions, adherens junctions and desmosomes to that of adults. Using immunostaining, our observations show, that tight junction proteins Claudin-2, Claudin-3 and Occludin, adherens junction proteins E-cadherin and β-Catenin as well as desmosomal proteins Plakoglobin and Plakophilin-2 appeared as mature as in adults as early as 25 weeks' gestation. However, Claudin-1, -4 and -5, as well as ZO-1 staining patterns increased and became more defined with increasing gestational age, suggesting junctional maturation during gestational week 26 and 27. Desmosomal protein Desmocollin-2 was increased until 26 weeks' gestation whereas Desmoglein-2 and Desmoplakin expression was immature at 28 weeks' gestation compared to the expression in adults. Our study provides the first sequential characterization of junctional protein maturation across all major IEB components early in life in human samples. These findings may help identify key mechanisms underlying intestinal barrier-associated pathologies in preterm infants.","42392304":"ID: 42392304\nTitle: Moderate-altitude hypoxia is associated with attenuated diet-induced liver injury and coordinated carbon-metabolic and lipid remodeling.\nAbstract: Chronic mild hypoxia at moderate altitude (2260 m) has been linked to improved systemic metabolism, but its liver-specific associations under high-energy diets remain incompletely defined. In this study, age-matched male C57BL/6 J mice were maintained for 15 weeks at simulated low altitude (50 m) or moderate altitude (2260 m) while fed a normal diet (ND), high-fat diet (HFD), or HFD with 30% fructose (HFD + HFr). Hepatic outcomes were assessed using ultrasonography, histology, electron microscopy, serum biochemistry, targeted energy metabolomics, lipidomics, and immunoblotting. Compared with the corresponding low-altitude high-energy diet groups, mice at 2260 m showed lower diet-associated weight gain, hepatic steatosis, and ALT/AST elevations. Structural analyses showed reduced lipid-droplet accumulation and qualitatively improved mitochondrial ultrastructural appearance. Metabolomics showed coordinated decreases in steady-state intermediates across glycolysis, the pentose phosphate pathway, and the tricarboxylic acid cycle relative to the 50 m HFD group, together with enzyme changes consistent with reduced lipogenic capacity and altered fatty-acid uptake/oxidation. Lipidomic profiling further showed lower accumulation of neutral lipids, including triglycerides and diacylglycerols, as well as sphingolipids, while phospholipid class-level composition appeared less disturbed. Overall, moderate-altitude exposure was associated with attenuation of high-energy-diet-related hepatic metabolic dysfunction and with coordinated metabolic remodeling. These findings identify chronic mild hypoxia as an important contextual factor associated with hepatic metabolic responses, while direct causal mechanisms require further validation.","42392328":"ID: 42392328\nTitle: Hierarchical analysis of metabolic phenotype reveals distinct microbiota and circulatory transcriptome in metabolic dysfunction-associated steatotic liver disease.\nAbstract: To investigate how visceral adiposity and insulin resistance, defined respectively by visceral adiposity index (VAI) and triglyceride-glucose (TyG) index, jointly influence gut microbiota composition and immune transcriptomes in metabolic dysfunction-associated steatotic liver disease (MASLD), and to explore potential mechanistic pathways. We enrolled 169 adults stratified by VAI, controlled attenuation parameter (CAP), TyG index, and physical activity. Gut microbiota and immune transcriptomes were profiled using 16S rRNA and RNA sequencing, respectively. Differentially expressed genes (DEGs) were identified across subgroups. Functional annotation and upstream regulatory networks were analyzed using DAVID and Ingenuity Pathway Analysis (IPA). Higher VAI correlated with obesity, inflammation, and steatosis, while the TyG index independently predicted fibrosis risk. Specific taxa, includingTM7x,Acidaminococcus, andDielma, were consistently enriched in adverse metabolic phenotypes. Transcriptomic analysis of circulating immune cells identified 348 TyG-associated DEGs significantly enriched in mitochondrial and cytokine signaling pathways. IPA highlighted IL6, SREBF1, PTGS1 and SNCA as central regulators linking metabolic stress to mitochondrial dysfunction. Gut microbiota shifts and immune transcriptome alterations jointly mediate the interplay between insulin resistance and visceral adiposity in MASLD. The identified insulin resistance-associated genes suggest that mitochondrial dysfunction and cytokine dysregulation contribute to obesity-related hepatic pathology, supporting precision strategies targeting VAI and metabolic dysregulation.","42392352":"ID: 42392352\nTitle: Renal failure-driven luminal ammonia production impairs gut barrier function in CKD.\nAbstract: Chronic kidney disease (CKD) is often associated with increased intestinal permeability, commonly referred to as \"leaky gut.\" This study aimed to investigate how uremic conditions affect gut barrier integrity using in vitro, ex vivo, and in vivo models. Caco-2 cells exposed to plasma from hemodialysis (HD) patients exhibited increased permeability. HD plasma selectively upregulated claudin-1 expression at both mRNA and protein levels, without affecting ZO-1 or occludin. Uremic toxins such as indoxyl sulfate and p-cresyl sulfate did not replicate these effects. CKD mice showed enhanced paracellular intestinal permeability, confirmed by elevated plasma levels of LBP and FD4, both in vivo and ex vivo. Claudin-1 overexpression was also observed in the colons of CKD mice. In addition, CKD mice displayed increased cecal ammonia concentrations. Exposure to ammonia, both in vitro and ex vivo, significantly disrupted epithelial barrier integrity and increased colonic permeability, supporting the hypothesis that bacterial urease activity and ammonia production contribute to gut barrier dysfunction in CKD. These findings reveal a potential mechanistic link between renal failure, luminal ammonia, and \"leaky gut.\"","42392672":"ID: 42392672\nTitle: Interplay between MASLD, obesity and type 2 diabetes: epidemiology, shared pathways and clinical implications.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD), obesity and type 2 diabetes mellitus (T2DM) are interconnected global epidemics that frequently coexist and mutually reinforce disease progression and adverse clinical outcomes. MASLD, the most prevalent chronic liver disease worldwide, is now recognised as a hepatic manifestation of systemic metabolic dysfunction. The coexistence of the triad markedly accelerates MASLD progression, heightens cardiometabolic risk and shifts mortality patterns towards cardiovascular disease, the leading cause of death in affected populations. However, most available data describe MASLD in association with either obesity or T2DM individually, while robust epidemiological or mechanistic evidence for their combined overlap remains scarce. This review synthesises current evidence on the epidemiological overlap and shared risk architecture linking MASLD, obesity and T2DM. We examine integrated pathophysiological and molecular mechanisms underpinning this triad, including insulin resistance, lipotoxicity, mitochondrial dysfunction, endoplasmic reticulum stress, transcriptional and epigenetic dysregulation and gut-liver axis perturbations. We further discuss the clinical implications of this shared biology, emphasising integrated screening strategies and presenting an evidence-based algorithm for non-invasive identification of advanced hepatic fibrosis within the triad. We review evidence-based therapeutic approaches, including mechanism-based pharmacological therapies, and highlight their differential effects on weight, glycaemic control and liver disease severity. Emerging research priorities and future directions for integrated cardiometabolic care are also outlined. Collectively, the review underscores the need for integrated hepatic-cardiometabolic care to improve clinical outcomes across this metabolic triad.","42392673":"ID: 42392673\nTitle: Liver fibrosis in metabolic dysfunction-associated steatotic liver disease: epidemiology, risk stratification and therapeutics.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) has become the most prevalent chronic liver disease worldwide and is tightly linked to cardiometabolic comorbidities. A major clinical focus on MASLD is the detection of hepatic fibrosis, which most strongly predicts liver-related events, hepatocellular carcinoma risk and mortality. While lifestyle modification and sustained weight loss remain foundational, therapeutic innovation has rapidly expanded, shifting the metabolic dysfunction-associated steatohepatitis (MASH) treatment landscape towards targeted pharmacotherapies that address metabolic stress, inflammation and fibrogenesis, particularly for moderate/advanced fibrosis (i.e., F2/F3 fibrosis and cirrhosis). This review summarises the burden and systemic complications of MASLD, highlights endocrine influences that modulate hepatic steatosis and disease severity and emphasises the central role of fibrosis staging and non-invasive risk stratification in clinical decision-making. We then synthesise emerging pharmacotherapies across key mechanistic axes, including incretin-based agents (GLP-1 receptor agonists and dual/triple agonists), hepatocyte-directed metabolic modulators (thyroid hormone receptor-β agonists, fatty acid synthase inhibitors, acetyl-CoA carboxylase and other de novo lipogenesis inhibitors), bile acid pathway therapies (FXR agonists) and pleiotropic metabolic-fibrotic regulators (fibroblast growth factor 21 [FGF21] analogues and peroxisome proliferator-activated receptor [PPAR] agonists). We also discuss combination strategies, candidate agents with potential direct antifibrotic activity and the growing role of genetic risk stratification and hepatocyte-targeted oligonucleotide therapeutics. Finally, we outline current surrogate endpoints used in clinical trials and propose future directions towards stage-specific, mechanism-informed and combination regimens to achieve persistent MASH resolution and meaningful fibrosis regression.","42392748":"ID: 42392748\nTitle: [Ameliorating effect of Citri Reticulatae Pericarpium on hypercholesterolemia in rats through promoting reverse cholesterol transport].\nAbstract: This study aimed to elucidate the therapeutic potential and underlying mechanisms of the Citri Reticulatae Pericarpium extract(CRPE) against hypercholesterolemia. A hypercholesterolemic rat model was established through a combination of a high-sugar, high-fat diet and ethanol administration. The experimental animals were systematically divided into several groups, including a normal control group, a disease model group, a positive control group treated with ezetimibe(1 mg·kg~(-1)), and three intervention groups receiving low, medium, and high doses of CRPE(1.25, 2.5, and 5 g·kg~(-1), respectively). High performance liquid chromatography(HPLC) revealed that CRPE mainly contained narirutin, hesperidin, and nobiletin. A comprehensive series of in vivo assessments were conducted to evaluate effects of the extract. These included measuring serum lipid levels and calculating the atherogenic index(AI) using an automated biochemical analyzer, quantifying total cholesterol(TC) and total bile acid(TBA) levels in liver tissues and fecal samples with commercial assay kits, evaluating microcirculatory blood perfusion in the tail using the Moor FLPI laser speckle contrast imaging system, and measuring hemorheological parameters with an automated hemorheometer. Furthermore, enzyme-linked immunosorbent assay(ELISA) was employed to measure the serum and hepatic levels of critical factors involved in cholesterol transport and metabolism. The expression of proteins related to the reverse cholesterol transport(RCT) pathway and bile acid synthesis and metabolism in the liver was meticulously examined by Western blot. In vitro cell experiments were performed to validate the effects of CRPE on cholesterol uptake and efflux in BRL and RAW264.7 cells. The findings demonstrated that CRPE effectively corrected dyslipidemia, enhanced microcirculatory perfusion, and ameliorated abnormal blood rheology. It reduced serum levels of oxidized low-density lipoprotein(ox-LDL), apolipoprotein B(ApoB), free cholesterol(FC), cholesteryl ester(CE), and acyl coenzyme A: cholesterol acyltransferase(ACAT), while simultaneously increasing the levels of lecithin: cholesterol acyltransferase(LCAT) and apolipoprotein A1(ApoA1). A notable reduction in hepatic TC and a significant increase in TBA content in both the liver and feces were observed. Mechanistically, the hypocholesterolemic effect of CRPE was attributed to its ability to upregulate the expression of pivotal proteins in the RCT pathway, including the low-density lipoprotein receptor(LDL-R), scavenger receptor class B type I(SR-BI), ATP-binding cassette sub-family G member 5(ABCG5), ATP-binding cassette sub-family G member 8(ABCG8), and ATP-binding cassette subfamily B member 1(ABCB1). Concurrently, CRPE modulated the expression of central regulators of bile acid homeostasis, such as the bile salt export pump(BSEP), the farnesoid X receptor(FXR), and cholesterol 7α-hydroxylase(CYP7A1). The in vitro experiments provided compelling corroborating evidence, showing that CRPE directly stimulated the uptake of NBD-cholesterol in BRL hepatocytes and promoted its efflux from RAW264.7 macrophages. In conclusion, CRPE ameliorates hypercholesterolemia by facilitating RCT and maintaining enterohepatic circulation homeostasis of bile acid.","42392795":"ID: 42392795\nTitle: [Research progress on intervention of active components of Bupleuri Radix in metabolic dysfunction-associated fatty liver disease based on multiple parallel strike theory].\nAbstract: Metabolic dysfunction-associated fatty liver disease(MAFLD) is a prevalent chronic liver disease worldwide. Due to its complex pathogenesis, there is currently no specific drug capable of intervening throughout the entire pathological process, nor a unified and definitive treatment protocol in clinical practice. In traditional Chinese medicine, MAFLD falls under the category of diseases such as "hypochondriac pain" and "liver disease", with the core pathogenesis being "stagnation of the liver meridian and obstruction of Qi movement". The pharmacological characteristics of Bupleuri Radix(BR), which "soothes the liver, relieves stagnation, and promotes Qi movement", are highly consistent with this pathogenesis. Furthermore, data mining studies have shown that BR is among the most frequently used herbs in TCM clinical protocols for treating MAFLD, and its herb pairs and classic formulas have demonstrated favorable therapeutic effects in clinical application. Modern pharmacological studies have also confirmed that BR is rich in active ingredients, including saponins(e.g., saikosaponin A/D/B2), volatile oils(e.g., D-limonene, hexanoic acid), flavonoids(e.g., quercetin, rutin, kaempferol), and polysaccharides. These active ingredients can target multiple pathological aspects of the "multiple parallel hits" in MAFLD, such as improving insulin resistance(IR), alleviating endoplasmic reticulum stress(ERS), repairing mitochondrial function, regulating oxidative stress(OS) response, modulating intestinal microbiota imbalance, and inhibiting inflammasome activation, thereby slowing the progress of MAFLD. Its mechanism of action is closely related to the regulation of PI3K/Akt, PPAR, Nrf2, AMPK, MAPK, PINK1/Parkin, NLRP3 inflammasome and the "gut-liver axis", reflecting the integrative regulatory advantages of TCM's multi-component, multi-target and multi-mechanism approach. Future in-depth studies should focus on precise component profiling of BR, validation of key targets, and the synergistic mechanisms within "formula-component" interactions to better leverage the value of BR in the prevention and treatment of MAFLD.","42393343":"ID: 42393343\nTitle: Docosahexaenoic acid alleviates DSS-induced colitis by regulating the gut microbiota and restoring the gut barrier.\nAbstract: Docosahexaenoic acid (DHA), a long-chain omega-3 polyunsaturated fatty acid, has well-recognized anti-inflammatory activity; however, the mechanisms underlying its protective effects in inflammatory bowel disease (IBD) remain incompletely understood. In this study, we investigated the effects of DHA in a dextran sulfate sodium (DSS)-induced mouse model of colitis and examined whether these effects were mediated by the gut microbiota. DHA administration markedly alleviated DSS-induced colitis, as indicated by reduced body weight loss, disease activity, mortality, colon shortening, histological injury, intestinal barrier disruption, and colonic inflammatory responses. 16 S rRNA gene sequencing showed that DHA reshaped the gut microbial community and increased the abundance of beneficial taxa, including Bifidobacterium. Antibiotic cocktail (ABX)-mediated microbiota depletion largely abolished the protective effects of DHA, whereas fecal microbiota transplantation (FMT) from DHA-treated donors transferred resistance to DSS-induced colitis to recipient mice. DHA also restored tight junction protein expression and increased the frequency of colonic regulatory T cells in a microbiota-dependent manner. These findings indicate that DHA alleviates experimental colitis by modulating the gut microbiota, restoring intestinal barrier integrity, and regulating mucosal immune homeostasis. DHA may therefore represent a promising dietary strategy for the prevention or adjunctive treatment of ulcerative colitis (UC).","42393642":"ID: 42393642\nTitle: MCD biomarkers Egfr, Hmox1, Lgmn identified in NAFLD.\nAbstract: Non-alcoholic fatty liver disease (NAFLD) is associated with metabolic cell death (MCD), and this study aimed to dig deeper into the biomarkers associated with MCD in NAFLD, and to provide new references for the diagnosis and treatment of NAFLD. The datasets and MCD-related genes (MCD-RGs) associated with NAFLD were downloaded from the Gene Expression Omnibus (GEO) database and the literature, respectively. Differentially expressed genes (DEGs) between NAFLD and control groups were identified and intersected with MCD-RGs to yield candidate genes. Biomarkers were obtained by screening under four machine learning models, Receiver Operating Characteristic (ROC) curves, and expression validation. Based on the biomarkers, functional enrichment, diagnostic model construction, network modulation, and reverse transcription-quantitative polymerase chain reaction (RT-qPCR) were performed. At the same time, differential infiltration of immune cells in the NAFLD and control groups was analysed. The 17 candidate genes were mostly involved in processes such as immunity and apoptosis. After screening, Egfr, Hmox1, and Lgmn were identified as biomarkers. Among these, Egfr was down-regulated whereas Hmox1 and Lgmn were up-regulated in NAFLD. Based on these biomarkers, a nomogram diagnostic model was constructed and demonstrated excellent predictive performance (AUC = 0.997). Subsequent enrichment analyses showed enrichment in inflammatory regulation between biomarkers and NAFLD groups. In addition, in the TF-biomarker network, Egfr and Hmox1 co-predicted NF-κB1. SORAFENIB was co-predicted in drug prediction. Meanwhile, five differentially infiltrating immune cells, such as CD8 T cells, were found to be strongly negatively correlated (cor = -0.475) with Egfr in both the NAFLD and control groups. In this study, Egfr, Hmox1, and Lgmn were used as biomarkers showing transcriptomic correlation with with MCD in NAFLD, and an excellent nomogram diagnostic model was developed accordingly, which is expected to provide a practical tool for diagnosis and treatment of NAFLD.

However, early metabolic biomarkers for subclinical atherosclerosis (SA) in MAFLD patients remain unclear. This study used untargeted metabolomics to investigate serum metabolite and pathway changes associated with SA in MAFLD patients and to screen for potential serum metabolic biomarkers. From December 2023 to December 2024, 64 MAFLD patients with SA enrolled in the \"Pan-Vascular Cohort Study\" at the Health Management Medical Center of the Third Xiangya Hospital of Central South University were included as an experimental group, and 50 age- and sex-matched MAFLD patients without SA were included as controls. MAFLD was diagnosed according to the Guidelines for the Prevention and Treatment of Metabolic (Non-Alcoholic) Fatty Liver Disease (2024 Edition). SA was defined by the presence of multi-segment arterial plaques and/or peripheral arterial obstruction. Untargeted metabolomics profiling was performed using ultra-high performance liquid chromatography coupled with mass spectrometry. Differential metabolites were screened using fold change (FC) analysis, principal component analysis, and orthogonal partial least squares discriminant analysis. Receiver operating characteristic (ROC) curves evaluated diagnostic performance of differential metabolites, and pathway enrichment analysis identified metabolic pathways associated with MAFLD and atherosclerosis. Using selection criteria of FDR-corrected q<0.05 and FC >1.5 or <0.67, a total of 415 differential metabolites were identified between the 2 groups. The top 5 differential metabolites were lysophosphatidylcholine (18꞉3), chelerythrine, N,N-hexamethylene thiocarbamate S-ethyl ester, N-ethyl-o-crotonylmethylaniline, and lysophosphatidylcholine (18꞉1). ROC analysis based on support vector machine (SVM) modeling of these top 5 metabolites yielded an area under the curve of 1. Differential metabolites were mainly enriched in histidine metabolism, sphingolipid metabolism, glycerophospholipid metabolism, unsaturated fatty acid biosynthesis, tryptophan metabolism, and taurine/hypotaurine metabolism. The metabolic profiles of MAFLD patients with and without SA differ significantly. Key differential metabolites may serve as potential biomarkers for predicting atherosclerosis in MAFLD patients. 目的: 代谢相关脂肪性肝病(metabolic dysfunction‑associated fatty liver disease，MAFLD)最常见的肝外并发症及死因是心血管疾病，MAFLD患者发生亚临床动脉粥样硬化(subclinical atherosclerosis，SA)的早期代谢标志物目前尚不明确。本研究通过非靶向代谢组学探索MAFLD患者发生SA的血清代谢物及代谢途径的变化，筛选潜在的血清代谢标志物。方法: 选取2023年12月至2024年12月在中南大学湘雅三医院健康管理医学中心“泛血管队列研究”纳入的64例MAFLD合并SA患者作为实验组，同期选取50例年龄、性别匹配的MAFLD未合并SA的受检者作为对照组。MAFLD诊断标准参照《代谢相关(非酒精性)脂肪性肝病防治指南(2024年版)》，采用多血管节段动脉粥样硬化斑块定义SA。使用超高效液相色谱和质谱仪进行非靶向代谢组学检测。采用差异倍数(fold change，FC)分析、主成分分析和正交偏最小二乘判别分析方法筛选差异代谢物，受试者操作特征(receiver operating characteristic，ROC)曲线评价差异代谢物的诊断效能，通路富集分析方法筛选与MAFLD及动脉粥样硬化发生相关的通路。结果: 基于差异代谢物筛选标准错误发现率(false discovery rate，FDR)-corrected q<0.05，FC>1.5或<0.67)，2组间共筛选出415个差异代谢物。排名前5的差异代谢物为溶血磷脂酰胆碱(18꞉3)、白屈菜红碱、N,N-六亚甲基硫代氨基甲酸-S-乙酯、N-乙基-邻巴豆酰甲基苯胺、溶血磷脂酰胆碱(18꞉1)。选取这5个差异代谢物使用支持向量机(support vector machine，SVM)进行建模并绘制ROC曲线，曲线下面积为1。差异代谢物主要富集于组氨酸代谢、鞘脂代谢、甘油磷脂代谢、不饱和脂肪酸生物合成、色氨酸代谢、牛磺酸与亚牛磺酸代谢等通路。结论: MAFLD患者是否发生SA的代谢谱存在显著差异，关键差异代谢物可能是预测MAFLD患者是否发生动脉粥样硬化的潜在生物标志物。.","42394565":"ID: 42394565\nTitle: [Oral-gut axis: the microbial and immune bridge linking periodontitis to inflammatory bowel disease].\nAbstract: Periodontitis and inflammatory bowel disease (IBD) are common chronic inflammatory diseases affecting the oral cavity and gut, respectively. Recent researches suggest a potential bidirectional link between them via the oral-gut axis. On one hand, periodontal pathogens, notably Porphyromonas gingivalis, can ectopically colonize the gut, driving and exacerbating intestinal inflammation through mechanisms such as disrupting the gut barrier and inducing helper T cell 17/regulatory T cell imbalance. On the other hand, the systemic inflammatory environment, immune-metabolic disturbances, and oral-specific lesions caused by IBD can significantly increase the risk and severity of periodontal tissue destruction. This review summarizes the current understanding of the microbial and immune mechanisms underlying the interrelationship between periodontitis and IBD. It aims to encourage further validation of causality through longitudinal cohort studies, exploration of microbiome-targeted interventions, and multidisciplinary collaboration, ultimately facilitating the development of integrated prevention and treatment strategies based on the oral-gut axis. 牙周炎和炎症性肠病（IBD）分别是口腔和肠道常见的慢性炎症性疾病。近年研究发现，两者可能通过口腔-肠轴存在双向关联。一方面，以牙龈卟啉单胞菌为代表的牙周致病菌可异位定植于肠道，通过破坏肠道屏障、诱导辅助性T细胞17/调节性T细胞失衡等机制驱动并加剧肠道炎症；另一方面，IBD所致的全身性炎症环境、免疫代谢紊乱以及口腔特异性病变，亦可显著增加牙周组织破坏的风险与严重程度。本文综述了牙周炎与IBD在微生物与免疫机制方面的相互关联及研究进展，以期通过纵向队列研究、微生物组靶向干预及多学科协作，进一步验证牙周炎与IBD的因果关联并探索基于口腔-肠轴的联合防治策略。.","42394773":"ID: 42394773\nTitle: Letter to the Editor: Circadian and microbial misalignment in metabolic dysfunction-associated steatotic liver disease - mechanistic insights and chronotherapeutic potential.\nAbstract: We read with interest the article by Rusman et al published in World Journal of Experimental Medicine. Beyond microbial composition, the gut-liver axis is a rhythmic system regulated by a bidirectional interaction between host clocks and the gut microbiota. Social jetlag induces \"temporal dysbiosis\", disrupting the timing of metabolites and compromising the intestinal barrier, which exacerbates metabolic injury in metabolic dysfunction-associated steatotic liver disease. Restoration of these rhythms through chronotherapeutic approaches provides an effective method to restore alignment and improve clinical outcomes. Specifically, social jetlag desynchronizes hepatic clocks and disrupts microbially-modified bile acid signaling, promoting fat accumulation. Chronotherapeutic strategies like time-restricted eating can effectively mitigate disease progression by \"reprogramming\" the liver transcriptome and reducing hepatic triglycerides.","42394828":"ID: 42394828\nTitle: Gut barrier dysfunction and multidrug-resistant bacterial translocation in adult critical illness: Mechanistic insights from a systematic review.\nAbstract: The gastrointestinal tract plays an important role in host defence during critical illness. Disruption of epithelial integrity, microbiome imbalance, and immune dysregulation have all been linked to the translocation of multidrug-resistant (MDR) organisms from intestinal colonization to invasive infection. However, whether these associations reflect true causal mechanisms remains uncertain, and available human evidence has not been comprehensively synthesized using current methodological standards. To systematically evaluate human evidence examining the relationship between intestinal barrier dysfunction, microbial colonization, and subsequent MDR infection in adult critical illness, with particular attention to study quality, heterogeneity, and potential confounding factors. This systematic review was conducted in accordance with PRISMA guidelines. A structured literature search was performed in PubMed, EMBASE, and the Cochrane Library (2000-2025) using predefined Boolean combinations and Medical Subject Headings. Prospective and retrospective cohort studies involving intensive care units (ICU) adults were included if they evaluated intestinal colonization, biomarkers of barrier dysfunction (citrulline and intestinal fatty acid-binding protein), microbiome alterations, or endotoxemia. Study selection and data extraction were undertaken independently by two reviewers, with disagreements resolved through discussion. Risk of bias was assessed using the Newcastle-Ottawa Scale and ROBINS-I tool. Owing to methodological and clinical heterogeneity, findings were synthesized using a structured narrative approach rather than meta-analysis. Across the included studies, intestinal colonization with carbapenem-resistant Enterobacteriaceae, carbapenem-resistant Klebsiella pneumoniae, Acinetobacter baumannii, and vancomycin-resistant Enterococcus was consistently associated with an increased risk of subsequent bloodstream infection. However, progression rates varied considerably across cohorts, likely reflecting differences in patient characteristics, antimicrobial exposure, and ICU practices rather than a consistent effect size. Biomarker studies showed reduced citrulline levels and elevated intestinal fatty acid-binding protein concentrations in patients with gastrointestinal dysfunction; however, these markers indicate enterocyte injury rather than directly measuring intestinal permeability or bacterial translocation. Microbiome analyses demonstrated reduced diversity and impaired colonization resistance, although the extent and timing of these changes were not uniform across studies. Taken together, the evidence supports a biologically plausible link between epithelial injury, dysbiosis, and infection risk, but does not establish a direct causal relationship, largely due to the observational design of available studies and the influence of confounding factors such as illness severity, antimicrobial exposure, and ICU environment. Gut barrier dysfunction appears to contribute to the pathogenesis of MDR infection in critically ill adults; however, current evidence supports association rather than causation. Early recognition of intestinal colonization and strategies aimed at preserving mucosal integrity may offer potential clinical benefit, although their effectiveness requires confirmation in well-designed prospective and interventional studies.","42395006":"ID: 42395006\nTitle: Microbiome-mediated pharmacology of ginseng: Mechanistic insights into metabolic regulation and therapeutic potential.\nAbstract: Ginseng, a traditional medicinal herb with a favorable safety profile, has long been used to promote systemic health. Recent studies reveal that many of its beneficial effects are mediated through interactions with the gut microbiota. Microbial enzymes convert parent ginsenosides into more absorbable and bioactive metabolites such as compound K, while ginseng reciprocally remodels the microbial community and metabolite composition by promoting the growth of beneficial taxa including Akkermansia, Bifidobacterium, and Lactobacillus. These bidirectional interactions modulate host metabolic, immune, and intestinal barrier functions. The ginseng-microbiome interplay regulates microbial and host-derived metabolites such as short-chain fatty acids, bile acids, and indole derivatives, which in turn activate key signaling pathways including FXR/TGR5, FFAR, AMPK, and Nrf2. Through these mechanisms, ginseng improves lipid metabolism, enhances insulin sensitivity, alleviates low-grade inflammation, and ameliorates metabolic abnormalities such as obesity, insulin resistance, and nonalcoholic fatty liver disease (NAFLD). This review provides a comprehensive synthesis of the ginseng-microbiota metabolic axis, focusing on its mechanistic basis in metabolic regulation and related disorders. We also highlight the therapeutic convergence between ginseng and probiotics possessing ginsenoside-hydrolyzing enzymes, discuss strategies for strain selection and co-administration, and outline future directions in precision, microbiome-informed formulations and clinical trial design. Collectively, current evidence supports the ginseng-microbiota interactions as a promising therapeutic platform for restoring metabolic homeostasis and managing metabolic diseases.","42395007":"ID: 42395007\nTitle: Korean red ginseng extract ameliorates high-fat diet-induced hyperlipidemia by modulating the gut microbiota-liver metabolic axis.\nAbstract: Korean Red Ginseng is recognized for its ability to modulate immune responses, alleviate fatigue, and combat aging, and shows promise in treating hyperlipidemia. However, comprehensive insights into its gut-liver axis mechanisms remain limited. Rats were assigned to a normal control group, an HFD-fed model group, and four groups treated with Korean Red Ginseng extract (RGE) at doses of 125 mg/kg, 250 mg/kg, 500 mg/kg, and 1000 mg/kg. The treatment groups administered RGE by gavage for 60 days while on an HFD. The study evaluated RGE's effects on hyperlipidemia and gut microbiota through serum biochemical analysis, hepatic histopathology, cecal metabolomics, 16S rRNA sequencing, and further investigated hepatic regulatory mechanisms using molecular biology techniques. After 60 days of treatment, RGE significantly reduced serum lipid levels and liver injury markers. Histological analysis using H&E and Oil Red O staining showed that RGE significantly reduced hepatic steatosis in comparison to the model group. LC-MS and 16S rRNA sequencing of cecal contents revealed that RGE remodeled gut microbiota composition, enhancing microbiota-derived metabolite production. Molecular analysis indicated that RGE activated hepatic PPARα, downregulated SREBP-1c, and partially restored basal cholesterol biosynthesis by upregulating HMGCR mRNA. These changes collectively reduced hepatic triglyceride accumulation and promoted cholesterol excretion. RGE alleviates HFD-induced hyperlipidemia and hepatic steatosis through a coordinated gut-liver axis mechanism, involving microbiota modulation, metabolic reprogramming, and regulation of hepatic lipid factors. These findings support RGE as a potential therapeutic option for hyperlipidemia and related metabolic disorders, using an \"excretion-centric\" strategy.","42395037":"ID: 42395037\nTitle: Metabolic dysfunction-associated steatotic liver disease and metabolic dysfunction-associated alcohol-related liver disease in human immunodeficiency virus.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) and metabolic dysfunction-associated alcohol-related liver disease (MetALD) have emerged as increasingly important sources of morbidity among people living with human immunodeficiency virus (HIV). Advances in antiretroviral therapy have substantially improved life expectancy in people living with HIV (PLWH), but have also unmasked a growing burden of metabolic comorbidities which contribute to steatotic liver disease. Recent shifts in nomenclature and the introduction of MetALD emphasize metabolic dysfunction and graded alcohol exposure as central drivers of disease and are particularly relevant to PLWH, a population in whom overlapping metabolic and behavioral risk factors are common. Epidemiologic studies demonstrate that MASLD affects approximately one-third to one-half of PLWH worldwide, often occurring at younger ages and lower body mass index thresholds than in HIV-negative individuals. Emerging data further highlight the synergistic contribution of metabolic dysfunction and alcohol use to accelerated fibrosis progression in PLWH. Pathophysiologic mechanisms linking HIV infection to MASLD and MetALD include chronic immune activation and systemic inflammation, antiretroviral therapy-associated metabolic effects, altered adipose tissue distribution, gut-liver axis dysregulation, and alcohol-metabolic synergy. This review synthesizes contemporary evidence on the definitions, epidemiology, pathogenesis, clinical assessment, and management of MASLD and MetALD in PLWH.","42395745":"ID: 42395745\nTitle: Aqueous extract of Duyun Maojian tea ameliorates the ileal microbiota and associated hepatic metabolome in HFD-induced obese mice.\nAbstract: Duyun Maojian tea (DYMJ), a renowned Chinese green tea, exhibits potential anti-obesity properties, though its mechanisms remain unclear. This study investigated DYMJ's regulatory effects using a high-fat diet (HFD)-induced obese mouse model, with Xuezhikang (XZK) as a positive control (HP). Hepatic/serum biochemical parameters, histopathology, liver metabolomics and ileal microbiota were analyzed. DYMJ significantly reduced body weight, hepatic malondialdehyde, aminotransferase activity and steatosis while enhancing superoxide dismutase activity. Gut microbiota analysis revealed that HFD-induced Firmicutes phylum related to energy dysregulation and insulin resistance was modulated by DYMJ. Notably, Anaerotruncus genus abundance was positively correlated with pyridoxal 5'-phosphate level. In contrast, XZK increased the abundance of Proteobacteria, potentially exacerbating insulin resistance despite improving energy metabolism. DYMJ treatment restored microbial balance closer to normal-diet (ND) conditions, particularly by elevating nicotinic acid adenine dinucleotide and enriching Bacteroidetes phylum species associated with metabolic health. These findings suggested that DYMJ mitigated obesity through dual mechanisms: alleviating oxidative stress and hepatic lipid accumulation, while reshaping gut microbiota toward a metabolic health-promoting composition. This study supports DYMJ as a safe dietary supplement for body weight management, and highlights the gut-liver axis as a pivotal target for addressing metabolic disorders.","42396442":"ID: 42396442\nTitle: Gut barrier-microbiota crosstalk in sepsis: from pathogenesis to potential therapies.\nAbstract: Sepsis is a systemic inflammatory response syndrome triggered by infection, frequently complicated by severe organ dysfunction and high mortality rates.

However, the precise mechanisms governing the interaction between the intestinal epithelium and gut microbiota, and how this interaction drives sepsis progression, still need to be elucidated. In this review, the functions of the intestinal epithelial barrier are first outlined, and the clinical significance of its altered permeability during sepsis is highlighted. Then, the physiological roles of the gut microbiota are further explored, detailing how dysbiosis and microbial metabolites influence disease progression and trigger both localized and systemic immune responses. Based on this, a logical framework for gut-originated systemic inflammation is proposed, and the potential adverse effects of current clinical supportive therapies on intestinal integrity are further discussed. Finally, the emerging sepsis treatment strategies that target gut function are summarized, aiming to provide novel insights and therapeutic directions for clinical practice.","42397592":"ID: 42397592\nTitle: Host-derived Limosilactobacillus reuteri supplementation improves piglet growth and gut integrity in heat-stressed sows.\nAbstract: Heat stress during late gestation and lactation impairs sow physiology and productivity, partly through altered stress responses, inflammation, and intestinal integrity. This study evaluated whether novel Limosilactobacillus reuteri strains isolated from high-performing sows under heat stress could mitigate these effects. Forty multiparous sows (twenty sows in parity three and twenty in parity four; average initial BW: 243.1 ± 18.2 kg) were assigned to a thermoneutral control (TN) or three heat-stress treatments: unsupplemented heat stress (HS), heat stress with a 4.65 log CFU/g L. reuteri (HS5), or heat stress with a 4.95 log CFU/g L. reuteri (HS10). Sow performance, stress indicators, inflammatory cytokines, antioxidant status, gut integrity markers, and fecal microbiota were assessed. Feed intake during lactation was higher in the TN and HS10 compared with the HS. Litter performance parameters showed no significant differences among groups. Piglet weight at weaning was increased (p = 0.015) in the TN and HS10 compared with the HS and HS5. Respiratory rate increased in heat-stressed sows. Hair cortisol concentrations were lower in the TN compared with the heat-stressed treatments. Serum tumor necrosis factor-alpha, interleukin (IL)-10, and IL-1β concentrations were lower in TN compared with heat-stressed groups. Serum zonulin was higher in HS than in TN and HS10, while occludin concentration was lower in TN compared with all heat-stress treatments. At the phylum level, the relative abundance of Firmicutes, Bacteroidota, and Spirochaetota was similar among groups. At the family level, the Pirellulaceae family was tended to be higher in HS than HS5 and HS10. At the genus level, the relative abundance of Terrisporobacter was higher in the HS10 compared with HS and HS5. Abundance of CPla-4_termite_group tended to increase in the HS. Supplementation with 4.95 log CFU/g host-derived L. reuteri strains improved feed intake and piglet growth under heat stress and modulated inflammatory and gut barrier markers, despite minimal effects on overall microbiota structure.","42398186":"ID: 42398186\nTitle: Molecular crosstalk of probiotics in gut health: A chemical perspective on metabolite-mediated pathways.\nAbstract: Intestinal diseases, encompassing conditions like inflammatory bowel disease, irritable bowel syndrome, and colorectal cancer, represent a significant global health burden. Their pathogenesis is intricately linked to gut microbiota dysbiosis, which disrupts intestinal barrier integrity and immune homeostasis. Probiotics, as live beneficial microorganisms, have emerged as promising therapeutic agents to restore gut ecological balance and alleviate disease symptoms. This review comprehensively synthesizes current knowledge on the multifaceted mechanisms of action of probiotics against intestinal diseases. It delves into their ability to regulate gut microbial composition, strengthen the intestinal barrier, modulate immune and inflammatory responses, influence host-microbe co-metabolism (e.g., SCFAs, bile acids, tryptophan), and alleviate oxidative stress. Furthermore, it evaluates their clinical applications across a spectrum of intestinal disorders and discusses emerging strategies such as engineered probiotics and postbiotics. Probiotics exert their beneficial effects through a complex interplay of mechanisms, including competitive exclusion of pathogens, production of antimicrobial compounds, and immunomodulation. Preclinical models demonstrate their considerable potential in ameliorating disease-specific pathologies by restoring microbial balance and enhancing gut barrier function. Future perspectives highlight the potential of precision interventions via strain synergy optimization, genetic engineering, and harnessing microbial metabolites, positioning probiotics as next-generation, targeted therapeutics for intestinal health management.","42398207":"ID: 42398207\nTitle: Kaempferitrin attenuates DSS-induced colitis by promoting ubiquitination-mediated degradation of the nuclear factor kappa B p65.\nAbstract: Inflammatory bowel disease (IBD), including colitis, is commonly associated with dysfunction of the intestinal barrier and inflammatory responses. Current medications used to treat IBD may cause severe side effects with long-term use. Previous studies have confirmed that Bupleuri Radix extract exhibits significant anti-inflammatory effects. However, the therapeutic effects of its active component, kaempferitrin (KPN), on dextran sulfate sodium (DSS)-induced colitis in mice and the underlying mechanisms remain largely unexplored. The aim of this study was to investigate the therapeutic effects of KPN on colitis in mice and explore its potential mechanisms. This study employed a DSS-induced colitis mouse model to evaluate KPN's therapeutic effects. Mice were divided into control, model, 5-Aminosalicylic Acid (5-ASA), and KPN treatment groups, followed by DAI, histopathology, inflammatory cytokines, gut barrier proteins, and gene expression. This investigation revealed that Kaempferitrin (KPN), an active constituent within Bupleuri Radix extract, attenuates pathological manifestations, inflammatory cascades, and barrier dysfunction in dextran sulfate sodium (DSS)-induced murine colitis. Integrative network pharmacology and transcriptomic analyses identify NDRG2 as a potential target of KPN in the treatment of colitis. Co-immunoprecipitation (Co-IP) and mass spectrometry showed that KPN enhanced the interaction between NDRG2 and NF-κB p65, whereas mechanistic studies in bone marrow-derived macrophages (BMDMs), supported by public single-cell RNA-seq analysis and NDRG2/F4/80 co-localization in inflamed colon tissues, indicated that macrophages represent a relevant cellular context for the KPNNDRG2-p65 axis. Through the utilization of a biotin-conjugated KPN probe, direct molecular interaction between KPN and NDRG2 was established, with site-directed mutagenesis revealing E164, P280, and M314 as critical amino acid residues mediating this interaction. Mechanistically, KPN promoted NDRG2-associated recruitment of FBXO11, facilitating K48-linked ubiquitination and proteasomal degradation of p65 in BMDMs, thereby suppressing NF-κB activation and inflammatory cytokine expression. Additionally, in vivo experimental evidence indicated that NDRG2 ablation (NDRG2-/-) substantially diminished the protective efficacy of KPN against DSS-induced colitis and compromised its capacity to inhibit p65. KPN directly engages NDRG2 and modulates a BMDMs-associated NDRG2-FBXO11-p65 axis to restrain NF-κB signaling, providing mechanistic insight into the anti-inflammatory effects of KPN in experimental colitis.","42398618":"ID: 42398618\nTitle: Dihydroberberine in metabolic disorders: Bioavailability, molecular mechanisms, toxicology, and future perspectives.\nAbstract: The global prevalence of metabolic diseases, including obesity, type 2 diabetes mellitus (T2DM), and metabolic dysfunction-associated steatotic liver disease (MASLD), continues to rise, representing a major global health threat and economic burden. Dihydroberberine (DHB), a reduced derivative of berberine (BBR), has recently garnered attention due to its superior lipophilicity and intestinal absorption. Pharmacokinetic studies suggested that DHB achieves significantly higher blood concentrations compared to BBR at equivalent doses. This review systematically synthesized the current preclinical evidence regarding the metabolic regulatory mechanisms of DHB. Key pharmacological targets identified in cell and animal models included the activation of AMP-activated protein kinase (AMPK) and glucokinase (GCK), modulation of lipid metabolism, and attenuation of inflammatory and oxidative stress pathways. Furthermore, DHB interacted extensively with the gut microbiota, acting both as a microbial metabolite of BBR and a modulator of microbial composition. Toxicological assessments indicated a favorable safety profile, although potential risks such as hERG channel inhibition required careful evaluation. Importantly, while in vitro and animal studies demonstrated significant metabolic benefits, human clinical trials assessing direct disease outcomes remained highly limited.

During weight loss, fat content was reduced in all investigated tissues after 1- and 5-months, except for erector spinae muscle fat that was reduced after 5 months. Finally, reductions in alanine aminotransferase, fasting plasma glucose and insulin, waist circumference, and diastolic blood pressure were key for explaining liver fat content after 5 months. Multiple fat depots were increased simultaneously in individuals with obesity, with personalized weight loss intervention leading to reductions in all investigated tissues, especially after 1 month, in individuals with obesity, NAFLD, and MetS. The trial registry number: NCT05699863.","42399316":"ID: 42399316\nTitle: Gut barrier integrity biomarkers are associated with increased inflammation and predict disease status in hospitalized COVID-19 patients.\nAbstract: The COVID-19 global pandemic persists as an endemic disease with case spikes and a significant continued burden on public health. One hallmark of severe COVID-19 is a dysregulated immune response that leads to systemic inflammation and contributes to disease severity but is not explained by viral replication alone. Severe COVID-19 has been shown to disrupt the gut microbiome and increase intestinal permeability which may contribute to immune dysregulation and systemic inflammation. Here, we investigated the differences in plasma biomarkers for intestinal permeability as well as circulating cytokines between healthy volunteers and patients hospitalized with COVID-19. Correlation analyses were used to characterize differences in biomarker relationships between groups, and a random forest model was used to assess their discriminative accuracy. Our results demonstrated that hospitalized COVID-19 patients have elevated concentrations of pro-inflammatory cytokines and microbial translocation markers, and the relationships between these biomarkers were significantly altered compared to healthy volunteers, especially those related to mucosa-associated homeostatic cytokines IL-17A and IL-23. Further, IL-6 and LBP were the top biomarkers for prediction accuracy in the random forest model. This work highlights the importance of managing microbial translocation in COVID-19 and its potential utility as a biomarker for disease severity.","42399985":"ID: 42399985\nTitle: Gut microbiota-derived extracellular vesicles: bridging microbial-host crosstalk in metabolic disorders.\nAbstract: Gut microbiota-derived extracellular vesicles have emerged as crucial mediators in microbe-host communication, not only facilitating intracellular communication, quorum sensing, and horizontal gene transfer among bacteria but also playing a central role in cross-kingdom dialogue. In recent years, bacterial extracellular vesicles (BEVs) have attracted widespread attention due to their ability to carry a diverse array of bioactive molecules-such as proteins, lipids, and nucleic acids-and deliver them to host cells, thereby precisely regulating host metabolic and immune homeostasis. This review systematically elaborates the entire biological process of BEVs, from their biogenesis to functional interactions with host cells, with a specific emphasis on revealing their roles in the pathogenesis of various metabolic diseases-including obesity, type 2 diabetes (T2DM), metabolic dysfunction-associated steatotic liver disease (MASLD), atherosclerosis, and hypertension-at both molecular and cellular levels. Furthermore, leveraging their inherent stability, biocompatibility, and targeting capabilities, we discuss the translational potential and challenges of BEVs in the diagnosis and treatment of metabolic disorders. Beyond summarizing the latest research advances on BEVs in metabolic disorders, this review provides a critical analysis of current mechanistic insights and clinical translation pathways, aiming to establish a theoretical framework for developing novel microbiome-based metabolic interventions. Deciphering the BEV-mediated microbiota-host interaction network holds promise for pioneering new strategies for the precision prevention and treatment of metabolic disease.","42400257":"ID: 42400257\nTitle: Microbial metabolite Urolithin A protects against inorganic arsenic-induced gut barrier dysfunction in humanized AS3MT mice.\nAbstract: Chronic exposure to inorganic arsenic (iAs) remains a major environmental health concern and is associated with significant gastrointestinal (GI) disorders, including gastroenteritis, diarrhea, and inflammatory bowel disease-like symptoms. Gut microbiota plays a critical role in mitigating arsenic toxicity, as germ-free or antibiotic-treated mice exhibit reduced fecal arsenic excretion and greater tissue accumulation. We previously showed that the microbial metabolite Urolithin A (UroA) protects against iAs-induced cytotoxicity, apoptosis, oxidative stress, and ROS production in vitro. In this study, using humanized AS3MT mice (mouse arsenic methyltransferase gene (As3mt)replaced with human AS3MT, hAS3MT), we evaluated the in vivo effects of iAs and UroA on gut barrier function. Long-term iAs exposure (100 ppb for 28 weeks) significantly reduced expression of tight junction proteins, indicating compromised intestinal barrier integrity. UroA treatment protected hAS3MT mice from iAs-induced gut permeability, inflammation, colon shortening, and elevated colon weight/length ratio. UroA also reduced iAs-induced inflammatory cytokines, myeloperoxidase (MPO) activity and preserved intestinal epithelial cell tight junction protein expression. Further, microbiome and metabolomic analysis suggested that UroA treatment protected from iAs-induced gut microbial dysbiosis, especially restored several beneficial bacterial strains and short chain fatty acids (e.g., acetate and butyrate) and led to gut homeostasis. Together, these findings demonstrate that UroA mitigates iAs-induced gut toxicity and restores microbiota homeostasis.","42401310":"ID: 42401310\nTitle: Mucin degradation by Akkermansia muciniphila promotes Alistipes-dependent tryptophan metabolism and Th17-driven autoimmunity.\nAbstract: Multiple sclerosis (MS) is an autoimmune disorder of the central nervous system associated with alterations in gut commensals, including Akkermansia muciniphila (A. muciniphila). However, its role in MS remains unclear. Here, we report elevated serum lipopolysaccharide (LPS) and anti-LPS IgG levels in patients with relapsing-remitting MS (RRMS), indicating compromised gut barrier integrity. Notably, RRMS patients also exhibited increased serum anti-A. muciniphila IgA and enhanced A. muciniphila-induced Th17 responses in peripheral blood mononuclear cells (PBMCs). Using experimental autoimmune encephalomyelitis (EAE), a mouse model of MS, we found that A. muciniphila colonization worsened EAE severity, with increased infiltration of GM-CSF+CD4+ and IL-17A+CD4+ T cells in spinal cord. Mechanistically, A. muciniphila colonization enhanced tryptophan metabolism and elevated levels of aryl hydrocarbon receptor (AhR) agonists, including indole derivatives, during EAE. Although A. muciniphila does not directly metabolize tryptophan, it promotes expansion of tryptophan-utilizing bacterium Alistipes onderdonkii (A. onderdonkii) through mucin degradation. We further demonstrate that A. onderdonkii utilizes mucin-derived metabolites, including galactose and N-acetylneuraminic acid (NANA). Importantly, dietary tryptophan restriction significantly attenuated EAE severity. Collectively, these findings reveal a cross-feeding mechanism in which A. muciniphila supports growth of A. onderdonkii, thereby enhancing microbial tryptophan metabolism and production of AhR agonists that drive Th17-mediated neuroinflammation.","42402302":"ID: 42402302\nTitle: Polysaccharide-gut microbiota interactions in metabolic diseases: Structural selectivity, mediating mechanisms, and evidence deficiencies: A review.\nAbstract: Polysaccharides from food and medicinal sources are promising candidates for nutritional interventions in chronic metabolic diseases. Because intact polysaccharides are generally poorly absorbed after oral administration, their systemic effects cannot be fully explained by conventional models of absorption and direct action on target organs. Increasing attention has therefore focused on their gastrointestinal fate and on how microbial utilization and gut-derived metabolites may influence host metabolism. This review examines how molecular weight, monosaccharide composition, glycosidic linkage type, branching, charge, and conformation affect resistance to upper gastrointestinal digestion, microbial recognition, and fermentation. It further evaluates the roles of short-chain fatty acids, bile acids, tryptophan-derived metabolites, and barrier-associated inflammatory signals in glucose homeostasis, lipid metabolism, and immune regulation. The strength of evidence varies substantially across these pathways. Short-chain fatty acid-related mechanisms and the gut-liver axis have relatively consistent preclinical support, whereas bile acid signaling and intestinal barrier pathways are supported by moderate mechanistic evidence. Tryptophan metabolite-mediated regulation and the gut-brain axis remain largely associative or preclinical, with limited validation in controlled human studies. These gut-derived processes may contribute to the regulation of metabolic dysfunction-associated steatotic liver disease (MASLD), obesity, insulin resistance, and cardiometabolic disorders. Future studies should establish causal links among defined glycan structures, selective microbial utilization, gut-derived mediators, and clinically relevant outcomes, while advancing standardized characterization, biomarker-guided evaluation, and carefully validated precision nutrition strategies.","42403914":"ID: 42403914\nTitle: Intestinal neutral ceramidase, microbial metabolites and epithelial fucosylation in MASH.\nAbstract: ","42403915":"ID: 42403915\nTitle: Intestinal neutral ceramidase exacerbates MASH pathogenesis.\nAbstract: Metabolic dysfunction-associated steatotic liver disease and its more severe manifestation, metabolic dysfunction-associated steatohepatitis (MASH), are intimately linked to genetic factors, gut microbiota and barrier alteration. Ceramidases and ceramides are associated with MASH, yet the role of intestinal neutral ceramidase in MASH development remains unclear. Murine models with intestinal epithelial cell (IEC)-specific depletion of neutral ceramidase (Asah2ΔIEC ) or aryl hydrocarbon receptor (AhR ΔIEC) were subjected to either a Western diet (WD) at 6 weeks old for 10-12 months to induce MASH, or a hydrogenated vegetable oil, sucrose, palmitate and cholesterol (HSPC) diet to accelerate MASH progression. Fecal microbiota transplantation was performed in germ-free mice. MASH is associated with the induction of neutral ceramidase, which reshapes the intestinal microbiota and metabolite profiles, leading to increased production of 2-hydroxyhippuric acid (2-HHA). We identified 2-HHA as an inhibitor of AhR signalling, a pathway that normally promotes intestinal fucosylation. Elevated 2-HHA suppresses AhR activity, reduces fucosylation and contributes to MASH and associated airway inflammation in mice fed WD or HSPC diet. Notably, IEC-specific deletion of neutral ceramidase decreases 2-HHA levels, restores AhR signalling, enhances fucosylation and protects against MASH. Consistently, intestinal AhR deficiency exacerbates MASH by reducing intestinal fucosylation, whereas supplementation with fucoidan increases fucosylation, improves barrier function and attenuates MASH. These findings identify intestinal neutral ceramidase as a key driver of MASH through a microbiota-2-HHA-AhR axis that impairs intestinal fucosylation and barrier function, highlighting a potential therapeutic target.","42404072":"ID: 42404072\nTitle: Evaluation of dietary curcumin-loaded mesoporous silica nanoparticles on growth, blood biochemistry, gut barrier integrity and enteric gas emissions in weaned piglets.\nAbstract: Weaning stress often impairs growth, metabolic function, gut barrier integrity, and microbial balance in piglets, underscoring the need for effective nutritional interventions to enhance post-weaning health. This study evaluated the effects of dietary curcumin-loaded mesoporous silica nanoparticles (SL@Cur) on growth performance, serum biochemical profiles, antioxidant capacity, gut epithelial integrity, gut microbial diversity, and fecal noxious gas emissions in weaned piglets. Thirty-six piglets (Duroc × [Yorkshire × Landrace]; 28 ± 1 days of age; 6-7 kg) were randomly assigned to diets containing 0, 30, or 60 mg/kg SL@Cur for 21 days. Piglets fed 30 or 60 mg/kg SL@Cur exhibited significantly higher final body weight, weight gain and average daily gain compared with control diet (p < 0.05). Myogenic gene expressions such as Pax7, Myf5 and Myf6 were significantly enhanced in piglets fed at 60 mg/kg SL@Cur compared to the control diet (p < 0.05). Serum triglycerides and total cholesterol levels were significantly reduced at 30 mg/kg (p < 0.05). The 30 mg/kg dose of SL@Cur also significantly decreased alanine aminotransferase and increased high-density lipoprotein concentrations than the control diet (p < 0.05). Serum glucose declined dose-dependently, whereas superoxide dismutase and cortisol remained unaffected. Gut barrier integrity was enhanced, as evidenced by significantly increased expression of tight junction proteins, zonula occludens-1 (ZO-1) and claudin-2 concentrations in SL@Cur supplied diets (p < 0.05). Analyzing the piglets' intestinal microbiomes showed that different dietary treatments lead to variations in their bacterial communities. As a result, the lower dose increased the presence of probiotics and lactic acid bacteria, while the higher dose showed more bacterial taxa and a mixed microbial shift. Additionally, SL@Cur markedly reduced fecal NH₃ and H2S gas emissions (p < 0.05). Overall, SL@Cur supplementation enhanced growth performance, improved metabolic and intestinal health parameters, and reduced enteric gas emissions in weaned piglets.","42404158":"ID: 42404158\nTitle: Comparative effects of β-glucan and mannan oligosaccharides on heat stress-induced inflammation: associations with gut barrier integrity and intestinal microbiota in mice.\nAbstract: Heat stress poses serious threats to human and animal health by inducing systemic inflammation, oxidative stress, and intestinal barrier damage, yet the potential of functional food components in mitigating heat stress-associated health impairments remains insufficiently explored. This study used a chronic heat stress model in C57BL/6 J mice to compare the protective effects of β-glucan (BG) and mannan oligosaccharides (MOS) against heat stress-induced injury. The underlying mechanisms of each supplement were also systematically investigated. The results demonstrated that both BG and MOS effectively attenuated heat stress-induced body weight loss, elevated liver index, and systemic inflammatory responses, significantly reduced serum levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and heat shock protein 70 (HSP70), and restored antioxidant enzyme activity. Notably, BG exhibited superior efficacy in suppressing pro-inflammatory cytokines and restoring serum immunoglobulin A (IgA) levels. Regarding intestinal barrier integrity, both oligosaccharides markedly upregulated the colonic expression of tight junction proteins zonula occludens-1 (ZO-1), Claudin-1, and Occludin, decreased serum diamine oxidase (DAO) and lipopolysaccharide (LPS) levels, and partially alleviated heat stress-induced intestinal barrier disruption. Hepatic tissue analysis revealed that both BG and MOS ameliorated heat stress-induced hepatic inflammation and lipid metabolism dysfunction. This was achieved by suppressing TLR4 and iNOS expression while restoring the balance of CD36 and PPARα expression. Furthermore, fecal microbial diversity analysis revealed that MOS was associated with increased abundance of Lachnospiraceae-related taxa, which are known to include short-chain fatty acid-producing bacteria. These microbial changes may contribute to the maintenance of gut microecological homeostasis via distinct microbiota-associated pathways. Collectively, these findings suggest that BG and MOS may alleviate multi-level heat stress-induced damage, potentially in association with improved intestinal barrier-related markers, altered gut microbiota composition, and modulation of gut-liver axis-related responses, thereby providing preliminary evidence for their potential application as functional food components to address heat stress-related health challenges.","42404519":"ID: 42404519\nTitle: Protein-losing enteropathy after the Fontan procedure - A cardiologist's and gastroenterologist's perspective.\nAbstract: Protein-losing enteropathy (PLE) is a severe, multifactorial complication of Fontan circulation that affects approximately 12% of patients with single-ventricle physiology. Because no universal standard therapy exists, management is individualized and guided by the dominant hemodynamic and lymphatic drivers, clinical severity, and local expertise. Chronically elevated central venous pressure and impaired lymphatic drainage promote lymph congestion and leakage into the intestinal lumen, leading to hypoalbuminemia, edema, diarrhea, malnutrition, and immune dysfunction. Treatment is multimodal and includes optimization of Fontan hemodynamics, symptomatic and anti-inflammatory pharmacotherapy, and targeted nutritional strategies (high-protein diet, medium-chain triglycerides, and supplementation). Advances in lymphatic imaging have enabled phenotype-based, lymphatic-directed interventions such as lymphatic embolization and thoracic duct decompression, which can improve outcomes in selected patients. When conservative and interventional strategies fail, heart transplantation remains the definitive option. Emerging evidence also highlights the potential contribution of the gut-liver axis, including intestinal barrier dysfunction and alterations in the microbiome, which may influence inflammation and disease persistence. This review summarizes current concepts in PLE pathophysiology and therapeutic approaches, with emphasis on lymphatic dysfunction and evolving adjunctive targets.","42404787":"ID: 42404787\nTitle: The gut microbiota-bile acid axis in liver transplantation: implications for postoperative complications and therapeutic strategies.\nAbstract: Liver transplantation (LT) is a critical intervention for end-stage liver disease, while complications, such as infections, graft rejection, and metabolic disturbances are common post-transplant. The gut microbiota-bile acid (GM-BA) axis plays a pivotal role in regulating liver function and overall health, influencing both the gut microbiota and bile acid metabolism. This review explored the complex interplay between the gut microbiota (GM) and bile acids during liver transplantation. It also discussed how disruptions in this axis can lead to post-transplant complications, such as infection, rejection, and liver injury. Specifically, the role of microbiota-derived bile acids was assessed in shaping immune responses and metabolic pathways that may impact liver graft function. Furthermore, therapeutic strategies aimed at modulating the GM-BA axis were reviewed to improve post-transplant outcomes, including the use of probiotics, prebiotics, and bile acid receptor modulators. Understanding the mechanisms behind GM-BA dysregulation may provide new directions for improving liver transplant survival and reducing complications.","42404798":"ID: 42404798\nTitle: Synergistic modulation of the gut microbiome-liver-host metabolome axis associates with the therapeutic efficacy of Danlou tablet against metabolic syndrome.\nAbstract: Obesity drives chronic diseases such as cardiovascular disease and diabetes. Danlou tablet (DLT), a traditional Chinese medicine formula, is used to treat coronary heart disease by regulating lipid metabolism, suggesting potential for addressing obesity-related metabolic dysfunction. However, its role in obesity and insulin resistance remains unexplored. We investigated the efficacy and mechanisms of DLT against high-fat diet (HFD)-induced obesity and insulin resistance. C57BL/6N mice were fed an HFD for 22 weeks and treated with DLT. A comprehensive phenotypic assessment was conducted, including body weight, glucose tolerance, insulin sensitivity, serum biochemistry, and histopathology of key tissues. To elucidate the therapeutic mechanism, we integrated 16S rRNA gene sequencing of gut microbiota, serum metabolomics (UPLC-Q-TOF-MS), and hepatic transcriptomics. DLT treatment counteracted HFD-induced metabolic dysfunction, reducing body weight, adiposity, dyslipidemia, and insulin resistance, while ameliorating hepatic steatosis, inflammation, and oxidative stress. At the microbial level, DLT restored gut microbial diversity, corrected the Firmicutes/Bacteroidota ratio, and modulated key genera. Metabolomics linked these changes to restored fatty acid β-oxidation. In the liver, transcriptomics showed that DLT reversed HFD-induced gene expression, suppressed inflammatory pathways and enhanced fatty acid oxidation and xenobiotic metabolism. Integrated multi-omics analysis revealed a strong correlative relationship that DLT's therapeutic benefits are associated with the modulation of the gut-liver axis, where remodeling of the gut microbiome is closely linked to the reprogramming of hepatic metabolic pathways. DLT counteracts HFD-induced obesity and insulin resistance via a multi-level regulatory mechanism that is closely associated with the modulation of the gut-liver axis, which involves suppressing pathogenic gut microbes, restoring fatty acid metabolism, and enhancing hepatic lipid catabolism and antioxidant defense. This comprehensive preclinical evidence supports the clinical translation of DLT as a novel therapeutic option for obesity and type 2 diabetes mellitus.","42404979":"ID: 42404979\nTitle: Exercise-induced intestinal barrier dysfunction: a potential contributor to athlete mental health.\nAbstract: Athlete mental health has become a growing concern across endurance, aesthetic and weight-sensitive sports. While psychosocial factors play major roles, emerging evidence suggests biological pathways related to gastrointestinal function may contribute. Intense exercise induces transient intestinal barrier dysfunction through splanchnic hypoperfusion, hyperthermia and tight-junction disruption, increasing permeability and microbial product exposure. These changes resemble biomarker patterns in psychiatric populations, where elevated zonulin, lipopolysaccharide and intestinal fatty-acid binding protein are associated with anxiety, depression and neuroinflammation. This viewpoint proposes a bidirectional model linking exercise-induced gut barrier stress and mood disturbance. Gut-derived signals including vagal afferent activation and cytokine-mediated tryptophan-kynurenine shifts may influence mood-regulating brain regions, while psychological stress reciprocally impairs gut integrity via corticotropin-releasing hormone and sympathetic activation. Female athletes may face heightened vulnerability through hypoestrogenic states and psychosocial pressures. While exercise physiology and psychiatric literatures remain separate, their convergence highlights an under-recognised dimension of athlete health warranting clinical awareness and Relative Energy Deficiency in Sport integration. Research priorities include longitudinal athlete studies and multi-omics approaches to determine whether gut barrier dysfunction is a contributor, modifier or parallel correlate of athlete mental health.","42406061":"ID: 42406061\nTitle: Bile Acid Pool Expansion and Hemodynamic Associations of the Secondary-to-Primary Bile Acid Ratio in Adult Fontan Circulation.\nAbstract: We previously reported that adults with Fontan circulation have elevated plasma bile acids, including multiple individual bile acid species, associated with frailty, impaired exercise capacity, and adverse resting and post-exercise hemodynamics. Whether the secondary-to-primary bile acid ratio provides additional insight into gut-liver-circulatory interactions in this population is unknown. We performed a secondary analysis of a previously published prospective cohort of 20 adults with Fontan circulation and 20 matched healthy controls. Primary bile acids were defined as cholic acid, chenodeoxycholic acid, and their direct conjugated, sulfated, glucuronidated, and dehydrocholic derivatives. Secondary bile acids included deoxycholic, lithocholic, ursodeoxycholic, hyodeoxycholic, and related downstream derivatives. The secondary-to-primary ratio was calculated as summed secondary-derived bile acids divided by summed primary-derived bile acids. Group comparisons used Mann-Whitney U testing. Within Fontan patients, associations with body composition, exercise performance, and resting/post-exercise hemodynamics were assessed using Spearman correlation with Benjamini-Hochberg correction. The secondary-to-primary ratio was numerically lower in Fontan patients than controls: 0.80 [0.39-1.22] vs. 1.32 [0.70-1.83]; P = 0.10. However, both primary-derived bile acids: 6333 [3473-10899] vs. 2102 [1166-3662] nM; P = 0.004, and secondary-derived bile acids: 4431 [2529-7095] vs. 2468 [1786-3660] nM; P = 0.008, were significantly increased. Within Fontan patients, higher ratio correlated with lower cardiac index/cardiac power index, and higher total peripheral resistance index. In adult Fontan circulation, bile acid pool expansion, particularly primary species, is the dominant abnormality. The secondary-to-primary ratio provides complementary compositional information and appears linked to hemodynamic burden. The ratio did not distinguish groups and should be interpreted with absolute pool size.","42406586":"ID: 42406586\nTitle: Associations of 24-Hour Accelerometer-Measured Movement Behaviors with Chronic Liver Disease and the Mediating Role of Proteomics and Metabolomics.\nAbstract: This study aimed to investigate the associations of 24-hour movement behaviours with chronic liver disease (CLD) incidence and liver-related mortality. Data were derived from the UK Biobank cohort, comprising 86,746 participants with accelerometer-measured 24h movement behaviours. We estimated the associations of behaviours with CLD incidence and liver-related mortality using Cox proportional hazard models. We also identified behaviours-associated proteomic and metabolic signatures and their roles in mediating the associations. Moderate-to-vigorous physical activity (MVPA) was inversely associated with liver-related risks, with the hazard ratios (HRs) per standard deviation (SD) increase of 0.74 (0.67-0.80) for CLD, 0.68 (0.61-0.75) for metabolic-associated fatty liver disease (MASLD), 0.81 (0.68-0.95) for cirrhosis, and 0.77 (0.64-0.94) for liver-related mortality, respectively. Sedentary behaviour (SB) was associated with higher risks of incident CLD (HR per SD: 1.12, 95% CI: 1.05-1.19), MASLD (HR per SD: 1.14, 95% CI: 1.06-1.22), cirrhosis (HR per SD: 1.15, 95% CI: 1.01-1.31), and liver-related mortality (HR per SD: 1.27, 95% CI: 1.10-1.47). Reallocating time from other behaviours to MVPA was associated with lower risks of CLD incidence and liver-related mortality. Multi-omics analyses identified distinct proteomic and metabolic signatures for each behaviour, with MVPA-related proteomic signature potentially accounting for 18.2% and metabolic signature potentially accounting for 3.0% of the association between MVPA and CLD risk. A higher proportion of MVPA and a lower proportion of SB over a 24-hour period was associated with lower risks of CLD incidence and liver-related mortality. Proteomic and metabolic signatures of behaviours may partly account for these associations.","42406801":"ID: 42406801\nTitle: MicroRNA In Metabolism-Related Fatty Liver Inflammation: Mechanisms and Clinical Translation Prospects.\nAbstract: Metabolic-associated steatohepatitis (MASH) represents a growing global public health challenge. Its complex pathogenesis involves multiple pathological pathways, including lipid metabolism, inflammation, and fibrosis, yet effective specific diagnostic and therapeutic approaches remain elusive. MicroRNAs (miRNAs), as key post-transcriptional regulators, play an important role in the development and progression of MASH. This narrative review examines the molecular mechanisms by which miRNAs regulate lipid accumulation, inflammatory activation, hepatocyte injury, and fibrosis in MASH, while exploring their potential as non-invasive biomarkers for diagnosis and prognosis assessment. Additionally, the article focuses on analyzing the progress of preclinical research and the translational challenges of targeted therapeutic strategies based on miRNA mimics and antagonists, including delivery issues, off-target effects, reproducibility, and long-term safety. Despite encouraging preclinical evidence, major hurdles remain in clinical translation, including the lack of standardized protocols, efficient liver-specific delivery systems, and comprehensive safety data. Addressing these limitations may enable miRNA-based diagnostics and therapeutics to become precision tools for MASH management, though further validation through large-scale prospective studies is required.","42407107":"ID: 42407107\nTitle: Farnesoid X receptor blockade attenuates morphological damage, intestinal secretion, and prevents mucus loss induced by SARS-CoV-2 spike protein in the mouse intestine.\nAbstract: The SARS-CoV-2 spike protein has been implicated as an important pathogenic factor, including in intestinal disorders. The farnesoid X receptor (FXR), a nuclear receptor highly expressed in the intestine, has been highlighted in several studies investigating its role in different intestinal dysfunctions. This study evaluated whether FXR blockade attenuates spike-induced morphological alterations and intestinal dysfunction. Balb/c mice were divided into three groups (PBS, Spike, and DY268-antagonist). A 2-3 cm jejunal loop was surgically prepared, and different substances were inoculated into the loops (200 μl of PBS or 200 μl containing 10 μg of spike protein or 100 μl of DY268 at μmol + 100 μl of spike), followed by 4-h resting period before euthanasia. Chloride (Cl-) was measured, and tissue samples were collected for histomorphometry analysis, mucin and MUC2 evaluation, Paneth cell assessment, malondialdehyde (MDA), and glutathione (GSH) levels. FXR antagonism attenuated alterations in all histomorphometric parameters, maintained mucin expression and Paneth cells and their granules, and reduced MDA levels, while restoring GSH in the intestinal loop. However, further studies are needed to understand the mechanisms by which FXR blockade modulates spike-induced intestinal effects. These findings may provide insights into novel targeted strategies for the management of intestinal disorders.","42409325":"ID: 42409325\nTitle: Dysregulation of the bile acid signaling network in non-alcoholic fatty liver disease: Mechanisms and a new paradigm of precision network pharmacology.\nAbstract: Non-alcoholic fatty liver disease (NAFLD) has emerged as the most prevalent chronic liver disease worldwide, characterized by complex pathogenesis and a lack of effective therapies. The bile acid (BA) \"synthesis-transport-signaling\" axis serves as a central hub integrating gut microbiota, host metabolism, and immunity, and its network dysregulation is a key driver of NAFLD progression. This review systematically elaborates how dysfunction of key enzymes, transporters, and receptors (e.g., farnesoid X receptor (FXR), Takeda G protein-coupled receptor 5 (TGR5)) within this axis drives hepatic steatosis, inflammation, and fibrosis by reshaping the BA pool, disrupting enterohepatic circulation, and perturbing receptor cross-talk. Current pharmacological strategies targeting single nodes are constrained by interspecies differences in BA profiles, network complexity, and off-target effects, posing significant challenges to their efficacy and safety. Consequently, we propose a paradigm shift from \"single-target\" approaches towards \"precision network pharmacology.\" This entails developing novel bile acid conjugates, dual-target or multi-target agents, designing rational combination therapies, and stratifying patients based on their BA metabolic phenotypes. Guided by human-relevant models and novel biomarkers, this framework aims to systemically restore BA signaling network homeostasis and enable personalized intervention, offering a novel theoretical and translational roadmap for conquering NAFLD.","42409332":"ID: 42409332\nTitle: Exploring the potential efficacy of Ziziphus spina-christi on restoring steroid sensitivity in severe asthma.\nAbstract: To determine whether Ziziphus spina-christi adjuvant restores steroid hyporesponsiveness in severe asthma by strengthening the gut epithelial barrier and inhibiting the STING sensing pathway. Chemical profiling of Z. spina-christi extract was performed using liquid chromatography mass spectrometry (LC/MS-MS). Steroid-hyporesponsive asthma was induced with house dust mite (HDM) and cyclic-di-GMP (c-di-GMP). Mice were treated with dexamethasone, Z. spina-christi, or combination therapy. The study assessed gut histopathology, epithelial tight junction proteins, lung inflammation, airway hyporesponsiveness, inflammatory phenotypes, STING pathway activation, and glucocorticoid response. Z. spina-christi exhibited a flavonoid-dominated chemotype enriched in quercetin-related compounds. Severe asthma induction was associated with significant gut epithelial injury, loss of tight junction proteins, and barrier dysfunction. Dexamethasone monotherapy failed to restore gut architecture or tight junction integrity. Conversely, Z. spina-christi markedly improved gut histology and reinstated expression of Claudin-1, Occludin, and ZO-1, with near-complete normalization observed with combination therapy. Restoring the gut barrier was associated with decreased airway inflammation, improved lung function, suppression of the STING pathway, and normalization of the GRα/GRβ ratio. Z. spina-christi enhances steroid sensitivity in severe asthma by restoring the gut epithelial barrier and reducing STING-driven inflammation.","42410322":"ID: 42410322\nTitle: Identification and Characterization of Novel Anti-inflammatory and Hepatoprotective Properties of Dual-Function Peptides Derived from Jinhua Ham: A Study Integrating Computational Modeling with the cGAS-STING Pathway.\nAbstract: The development of bioactive peptides derived from food is crucial for alleviating nonalcoholic fatty liver disease. As a traditional meat product, Jinhua ham is rich in various bioactive peptides and has anti-inflammatory and liver-protective effects. This study aims to isolate novel dual-function peptides with anti-inflammatory and hepatoprotective properties from Jinhua ham hydrolysates. Potential target peptides were identified through mass spectrometry and computational virtual screening, followed by molecular docking and molecular dynamics simulations.

This work aimed to evaluate the inclusion of this strain in a novel fermented goats' milk to ensure a balance between probiotic viability and physical properties of the final product. The influence of both the culture and fermentation temperatures was examined in relation to their effects on rheological properties. The probiotic-added product fermented at 42 °C showed satisfactory viscoelastic properties comparable to those of commercial products. Moreover, it is a high-protein fermented milk with an in vitro amino acid digestibility of 96.5% and a moderate content of carbohydrates and fat. The probiotic milk exhibited a distinctive amino acid and peptide profile, with various identified peptides matching sequences previously reported to be beneficial for the gut barrier and metabolic health.","42412329":"ID: 42412329\nTitle: Mitophagy in Metabolic Dysfunction-Associated Fatty Liver Disease: Mechanisms, Regulatory Networks, and Therapeutic Perspectives.\nAbstract: Metabolic dysfunction-associated fatty liver disease (MASLD) represents the most prevalent chronic liver disorder globally, with pathogenesis closely linked to insulin resistance, obesity, and gut microbiota dysbiosis. Mitochondrial dysfunction is central to MASLD progression, and mitophagy-a selective form of autophagy that clears damaged mitochondria-plays a crucial role in maintaining cellular homeostasis. This review systematically delineates the molecular mechanisms, regulatory networks, and therapeutic implications of mitophagy in MASLD. We first outline the core machinery of mitophagy, encompassing both ubiquitin-dependent and ubiquitin-independent pathways. We then discuss how impaired mitophagy drives the disease progression of MASLD from the perspective of different hepatic cell types. Furthermore, we summarize the multilayered upstream regulatory network governing mitophagy in the context of MASLD, involving key signaling pathways, metabolic reprogramming, inflammatory cues, epigenetic modifications, and intercellular crosstalk. Finally, we examine therapeutic strategies targeting mitophagy-including clinical and preclinical agents, natural compounds, physical interventions, and emerging technologies-and highlight the challenges posed by its dualistic nature. Moving forward, integrating spatiotemporal dynamics with precision targeting will be essential to translate mitophagy modulation from mechanistic insight into viable clinical therapies for MASLD.","42413475":"ID: 42413475\nTitle: A liver phosphatase reprograms gut stem cells to drive hyperglycemia.\nAbstract: Why is fatty liver disease associated with hyperglycemia? In this issue, Ye, Wan, Liu, Deng, Zhang et al.1 propose an unexpected mechanism: hepatic alkaline phosphatase released from diseased liver suppresses intestinal stem cell differentiation into GLP-1-secreting L-cells. This study reveals a new pathogenic route of liver-intestine communication.","42413530":"ID: 42413530\nTitle: Barrier restoration as a therapeutic strategy for disorders of gut-brain interaction.\nAbstract: Disorders of gut-brain interaction, such as irritable bowel syndrome and functional dyspepsia, are increasingly linked to defects in gut barrier function. Mucosal disruption, encompassing alterations in the epithelial and mucus layers, leads to enhanced intestinal permeability, microbial translocation, and aberrant immune and neuronal signalling, potentially contributing to symptom severity. Despite growing recognition of barrier dysfunction in disorders of gut-brain interaction, clinical interventions remain largely symptom-based, with few therapies designed to directly restore epithelial integrity. In this Review, we examine the cellular and molecular pathways underpinning gut barrier function and highlight evidence supporting the role of diet, microbiome-targeted interventions, stress modulation, and pharmacological agents in maintaining or restoring intestinal permeability. Mechanistic insights reveal that short-chain fatty acids, amino acids (glutamine and tryptophan), and targeted probiotics can enhance tight junction integrity and mucin secretion, whereas psychological stress, low-fibre diets, and high-fat diets disrupt these pathways. We also discuss novel therapeutics, including antihistamines, mast cell stabilisers, protease inhibitors, secretagogues, and guanylate cyclase C agonists, and emerging technologies, such as vagal nerve stimulation and barrier-protective hydrogel delivery systems. Although promising, these strategies require validation in well designed clinical trials with targeted endpoints, and patient stratification based on microbial and immune phenotypes. By integrating advances in molecular biology with translational therapeutics, interventions targeting intestinal permeability could shift the treatment paradigm for disorders of gut-brain interaction from general symptom management to personalised disease modification.","42413768":"ID: 42413768\nTitle: Time-restricted eating, liver health, and fecal microbiota in adults with overweight or obesity: a randomized controlled trial.\nAbstract: The optimal eating window for time-restricted eating (TRE) remains unclear. We investigated the effects of 8-hour TRE combined with usual care (UC, a Mediterranean diet-based education program), versus UC alone over 12 weeks on hepatic fat fraction, liver health markers, and fecal microbiota in adults with overweight or obesity. In this multicenter randomized trial, participants (50% women) were assigned to UC (n=49), early TRE (n=49), late TRE (n=52), or self-selected TRE (n=47). Hepatic fat fraction was assessed by MRI; liver markers included elastography-based parameters, liver enzymes, and circulating biomarkers. Fecal microbiota was analyzed by 16S rRNA gene sequencing. Hepatic fat fraction decreased significantly within the three TRE groups (all P≤0.02), but no between-group differences were observed when comparing early TRE (mean difference [MD]: -0.4%; P=0.95), late TRE (MD: -1.5%; P=0.15), and self-selected TRE groups (MD: -0.7%; P=0.77) with the UC group, or among the TRE groups themselves (all P≥0.41). Similarly, no between-group differences were found in liver health markers and fecal microbiota. Participants with metabolic dysfunction-associated steatotic liver disease at baseline as well as those achieving ≥5% weight loss had greater reductions in hepatic fat fraction than those who did not (MD: -2.7 and -2.6%; respectively, both P<0.001). A higher proportion of participants in the TRE groups achieved ≥5% weight loss compared with UC (41-44% vs 16%; P=0.001). These findings suggest that the timing of the eating window in TRE may not impact hepatic fat fraction or microbiota composition beyond the effects of weight loss, though the study was not powered for secondary outcomes. The study was registered on ClinicalTrials.gov (identifier: NCT05310721). NCT05310721 IMPACT AND IMPLICATIONS: Time-restricted eating (TRE) is increasingly used for obesity management, but whether the timing of the eating window influences liver health remains unclear. In this 12-week multicenter randomized trial, adding early, late, or self-selected 8-hour TRE to Mediterranean diet-based usual care led to within-group reductions in MRI-assessed hepatic fat fraction, but did not confer greater improvements in hepatic fat fraction, liver health markers, or fecal microbiota than usual care alone. Participants with baseline metabolic dysfunction-associated steatotic liver disease (MASLD) and those achieving ≥5% weight loss experienced larger reductions in hepatic fat fraction, suggesting these reductions in this context are more closely linked to weight loss and baseline steatosis than to eating-window timing. Clinically, these findings support prioritizing feasible eating schedules and strategies that help patients attain clinically meaningful weight loss, particularly among individuals with MASLD.","42415055":"ID: 42415055\nTitle: Dual regulation of bile acids: ameliorating hepatic glycolipid disorders and restoring intestinal health in HFHC-challenged Yellow River carp (Cyprinus carpio L.).\nAbstract: This study was designed to investigate how three distinct bile acids (BAs) modulate glycolipid metabolic disorders and hepatointestinal injury induced by excessive intake of lipids and carbohydrates in Yellow River carp (Cyprinus carpio L.) and elucidate the underlying mechanisms involved. Here, the fish were randomly assigned to five groups: a control group (CON), a high-fat high-carbohydrate diet (HFHC) group, a HFHC + 300 mg/kg chenodeoxycholic acid (CDCA) group, a HFHC + 300 mg/kg ursodeoxycholic acid (UDCA) group and a HFHC + 300 mg/kg hyodeoxycholic acid (HDCA) group. The results revealed that the serum triglyceride, glucose, and total cholesterol levels were significantly elevated in HFHC-fed fish, accompanied by increased glutamic-oxaloacetic transaminase (GOT) and glutamic-pyruvic transaminase (GPT) activities in the serum and hepatopancreas. However, dietary supplementation with bile acids in the HFHC diet significantly improved these negative changes. Analysis of BA-glycolipid metabolism-related gene expression and enzyme activities in the hepatopancreas revealed that CDCA and HDCA inhibited gluconeogenesis (FBPase/PEPCK/G6Pase) and lipogenesis (SREBP-1/FAS), while promoting glycogen accumulation (genes and glycogen levels) and fatty acid β-oxidation (PPARα) via activation of the FXR (farnesoid X receptor) /SHP (small heterodimer partner) pathway. In contrast, dietary UDCA supplementation increased intestinal TGR5 (takeda G protein-coupled receptor 5) expression and suppressed the activities of two key gluconeogenic enzymes, PEPCK and G6Pase. Additionally, dietary BAs supplementation alleviated HFHC diet-induced intestinal inflammation by inhibiting the NF-κB (Nuclear Factor κB) pathway. Bile acids relieved gut dysbiosis, improved microbial alpha diversity and community structure, and enriched beneficial bacteria including Cetobacterium somerae. These microbial changes eventually modulated host substance synthesis and metabolism. HE staining showed that HFHC diet caused hepatopancreatic lesions and intestinal morphological damage in Yellow River carp, which were effectively alleviated by bile acid addition. In conclusion, HFHC diets disrupt fish glycolipid metabolism and impair hepato-intestinal health in Yellow River carp, whereas dietary BAs can attenuate these detrimental effects by modulating metabolic pathways and the gut microbiota composition.","42415381":"ID: 42415381\nTitle: Functional Bioactive Components in Non-Bovine Milks: A Comparative Review of Health Benefits and Potential Applications.\nAbstract: Nonbovine milks are gaining significant attention in health research due to their distinct nutritional and bioactive profiles. This review summarizes the functional components─including osteopontin, lactoferrin, casein, milk fat globule membrane (MFGM), ω-3 fatty acids, exosomes, and milk oligosaccharides─found in these specialty milks and their biological activities. Preclinical evidence suggests these components have the potential to exert health-promoting effects, with possible applications in immunomodulation, gut barrier enhancement, neurodevelopment, anti-inflammatory, and antioxidant activities. Interspecies variations in bioactive composition suggest specific nonbovine milks may offer targeted advantages for various health applications. However, given that most findings derive primarily from in vitro and animal studies, well-designed human clinical trials are necessary to validate these potential health benefits and elucidate underlying mechanisms in humans. This review highlights the potential of nonbovine milks as sustainable functional ingredients for tailored foods, supplements, and therapeutic formulations promoting human health.","42416830":"ID: 42416830\nTitle: Therapeutic potential and mechanisms of flavonoids from Citrus grandis 'Tomentosa' in metabolic dysfunction-associated steatotic liver disease: a focus on immune-inflammatory signaling pathways.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) constitutes a major global health burden, with limited therapeutic options currently available. Flavonoids derived from natural plants exhibit promising antioxidant and anti-inflammatory bioactivities, making them potential preventive and therapeutic agents for metabolic liver diseases. Citrus grandis 'Tomentosa' (CGT) flavonoids have shown hepatoprotective properties in preliminary preclinical investigations. However, a systematic and critical evaluation of the preclinical evidence supporting their application in MASLD, particularly regarding immune-inflammatory regulatory mechanisms, remains absent. This scoping review aimed to comprehensively map and critically appraise preclinical studies concerning the efficacy and molecular mechanisms of CGT flavonoids in MASLD, with a specific focus on immune-inflammatory signaling modulation. A scoping review methodology was applied to synthesize current preclinical evidence on CGT flavonoids for MASLD. Following standardized literature retrieval and screening procedures, a total of 22 eligible studies were included for qualitative evidence synthesis. The pharmacological effects, mechanistic findings, and methodological limitations of existing studies were systematically summarized and critically assessed. Synthetic analysis of the included studies demonstrated that CGT flavonoids effectively ameliorate hepatic steatosis, inflammatory responses, and oxidative stress in experimental MASLD models. The underlying mechanisms are preliminarily associated with the modulation of NF-κB, MAPK, and JAK-STAT signaling pathways, as well as the regulation of immune cell polarization. Nevertheless, most mechanistic evidence remains indirect and inconclusive, largely derived from non-CGT preparations or non-MASLD models, with a lack of direct target validation. The current body of evidence presents critical research gaps, including potential experimental artifacts caused by pan-assay interference, insufficient pharmacokinetic profiling, and inadequate rigorous studies validating CGT-specific regulatory effects on hepatic immune components, such as Kupffer cells and intrahepatic T-cell subsets under MASLD pathological conditions. The present scoping review confirms the preclinical potential of CGT flavonoids as novel botanical candidates for MASLD treatment, primarily through the suppression of hepatic steatosis, oxidative damage, and immune-inflammatory activation. However, existing evidence is methodologically limited and insufficient to support clinical translation. To address current deficiencies and facilitate translational progress, further rigorous mechanistic validation, standardized CGT flavonoid preparation protocols, and well-designed clinical investigations are urgently required. This work provides a balanced, evidence-based, and critical framework to guide future basic research and translational studies targeting CGT flavonoids for MASLD intervention.","42417510":"ID: 42417510\nTitle: Linking (Poly)Tungstate Speciation to Toxicity and Bioaccumulation in Daphnia magna.\nAbstract: Tungsten is an emerging pollutant commonly assumed to occur as the simple oxyanion tungstate, yet it often condenses into a suite of polytungstates in polluted waters. Despite growing recognition that tungstate polymerization modulates tungsten's environmental fate, its effects on toxicity remain largely unexplored. Here, we tracked the (de)polymerization behavior of three representative (poly)tungstates and examined its associations with multiple measures of acute toxicity to Daphnia magna, including the median lethal concentration (LC50), toxicokinetics, reactive oxygen species (ROS) content, metabolomics, and histology. While tungstate remained stable, W12 metatungstate and phosphotungstate depolymerized to different extents, yielding three distinct polymerization regimes in the exposure media. Monomeric tungstate exhibited high LC50, rapid uptake and efficient excretion, weak ROS signals, and minimal disruption of intestinal integrity. Oligomeric tungstates displayed lower LC50 than tungstate, consistent with slow depuration that generated high internal burdens, ROS accumulation, and suppression-oriented metabolic responses. High-order polytungstates, despite limited uptake and low ROS levels, were associated with structural disruption including irreversible gut barrier damage and mitochondrial collapse and displayed the lowest LC50. Together, these results suggest that tungstate polymerization not only amplifies tungsten toxicity but also alters its mode of action, supporting mechanistic interpretation and prediction of its ecotoxicological dynamics.","42419122":"ID: 42419122\nTitle: Discovery of cis-Gnetin H from peony seed coat as a potent antifibrotic agent modulating hepatic fibro-inflammatory pathways and gut microbiota homeostasis.\nAbstract: Liver fibrosis is a reversible stage of chronic liver disease lacking effective therapies. The peony seed coat, a major byproduct of peony oil production, is rich in bioactive stilbenes. However, its anti-fibrotic potential and underlying mechanisms remain systematically unexplored. This study aimed to isolate stilbenes from peony seed coat, identify the potent anti-fibrotic compounds, and evaluate their anti-fibrotic activity and mechanisms of action. A structure-oriented separation strategy, guided by spectroscopic analysis, enabled the isolation of stilbenes. Anti-fibrotic activity was screened in TGF-β1-induced hepatic stellate cells (HSCs). In vivo efficacy was evaluated in a CCl₄-induced mouse liver fibrosis model. Mechanisms were investigated using transcriptomics, Western blotting, and 16S rRNA gene sequencing. Among seven isolated stilbenes, cis-Gnetin H exhibited the most potent inhibition of HSCs activation by downregulating α-SMA, Collagen I, and Smad3. In CCl₄-treated mice, cis-Gnetin H significantly ameliorated liver injury, inflammation, and fibrosis. Mechanistically, cis-Gnetin H activated the Nrf2/HO-1 antioxidant pathway while suppressing NF-κB and TGF-β1/Smad signaling. Furthermore, cis-Gnetin H remodeled the gut microbiota by enriching beneficial genera and reducing pathogenic Staphylococcus. This microbial modulation was accompanied by increased production of SCFAs, which correlated strongly with improved hepatic parameters. cis-Gnetin H acts as an anti-fibrotic agent through modulating hepatic inflammatory and fibrotic signaling, and regulating the gut-liver axis via microbiota restoration and metabolite enhancement. These findings highlight cis-Gnetin H as a promising therapeutic candidate and support the high-value utilization of peony agricultural byproducts.","42420150":"ID: 42420150\nTitle: Sleeve gastrectomy versus Roux-en-Y gastric bypass for nonalcoholic fatty liver disease: a systematic review and meta-analysis.\nAbstract: The efficacy of sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) in the treatment of nonalcoholic fatty liver disease (NAFLD) has not been fully elucidated. The purpose of this systematic review and meta-analysis is to provide reliable evidence for clinical interpretation of the advantages and disadvantages of RYGB and SG in the treatment of NAFLD by directly comparing the efficacy of RYGB and SG in the treatment of NAFLD. All over the world. PubMed, Embase, Web of Science, and ClinicalTrials.gov were searched for relevant articles up to December 2025. Mean difference (MD) and 95% confidence interval (CI) were used for quantitative synthesis of continuous variables, and risk ratio and 95% CI were used for quantitative analysis of categorical variables. The primary outcomes of the study were changes in NAFLD activity score (NAS), fibrosis stage, and changes in liver enzymes (including alanine aminotransferase and aspartate aminotransferase) from initial to follow-up. Secondary outcomes included changes in body weight, body mass index, percentage total weight loss, and percentage excess weight loss. A total of 16 original studies were included in our final meta-analysis. Our primary analysis showed no significant overall difference between SG and RYGB in improving NAS (MD = .23, 95% CI: .69-1.16). Exploratory subgroup analyses suggested potential time-dependent patterns, although these varied by outcome: longer-term follow-up (> 1 year) was associated with a point estimate favoring RYGB for NAS (MD = .75, 95% CI: .03-1.47), but favoring SG for alanine aminotransferase reduction (MD = -5.92, 95% CI: -8.24 to 3.60). No significant between-group difference was observed for aspartate aminotransferase changes (P = .18), and RYGB was associated with greater weight loss. Given the exploratory nature of these subgroup analyses, these findings should be interpreted cautiously and considered hypothesis-generating. Metaregression analysis revealed that the difference in weight loss between procedures was significantly associated with the effect size for NAS improvement (β = -.11, 95% CI: -.21 to .01, P = .032) and accounted for 100% of the between-study heterogeneity (R2 = 100%). Although our primary analysis showed no significant overall difference between SG and RYGB in improving NAS, RYGB was associated with greater weight loss. Metaregression findings suggested that any potential histological advantage of RYGB may be largely attributable to its superior weight loss efficacy rather than to weight-independent mechanisms. Exploratory subgroup analyses suggested potential differences in long-term histological outcomes that varied across measures and should be considered hypothesis-generating. These findings warrant confirmation in future prospective studies.","42420514":"ID: 42420514\nTitle: Effects of hesperidin, nanohesperidin and obeticholic acid on hepatic FXR and SMAD3 in HFD/fructose-fed mice.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a growing global health concern, ranging from simple steatosis to advanced fibrosis. SMAD3 promotes liver injury, while Farnesoid X Receptor (FXR) regulates lipid metabolism and may have protective effects. This study evaluated the preventive and therapeutic effects of hesperidin, nanohesperidin and obeticholic acid (OCA) in an HFD/fructose-fed mice, focusing on FXR and SMAD3 levels. Forty-eight female C57BL/6J mice were utilized in prevention (10 weeks) and recovery (20 weeks) protocols. Hepatic and serum SMAD3 and FXR protein levels were measured by ELISA, gene expression by qPCR, and liver injury markers (ALT, AST) were also evaluated. No significant differences in body weight were observed between the experimental groups (p > 0.05). In the recovery protocol, nanohesperidin treatment exhibited the highest hepatic FXR protein levels (p > 0.05). Serum SMAD3 levels were significantly lower in hesperidin, nanohesperidin and OCA study groups than in the control group. Although there were significant reductions in AST levels in the treatment groups, no statistically significant differences were detected in hepatic mRNA expression levels for FXR or SMAD3 (p > 0.05). These findings suggest that hesperidin, nanohesperidin, and OCA may influence fibrosis-related pathways in experimental MASLD, possibly through modulation of FXR and SMAD3 signaling. The more pronounced FXR response observed with nanohesperidin indicates that formulation strategies may affect the biological activity of hesperidin.","42420833":"ID: 42420833\nTitle: Harnessing probiotics to combat nonylphenol toxicity: a multiomics approach of gut microbiome remodelling in Silurus meridionalis.\nAbstract: As a ubiquitous environmental endocrine disruptor, nonylphenol (NP) threatens aquatic organisms, driving the need for sustainable mitigation strategies. While probiotics represent promising eco-friendly supplements, their molecular mechanisms against NP toxicity remain unclear. In this study, S. meridionalis received 7-week of probiotic (Bacillus subtilis and Lactobacillus acidophilus) pretreatment followed by 15 days of NP exposure. Integrated metagenomics, transcriptomics, and metabolomics analyses, with Reverse transcription quantitative real-time PCR (RT‒qPCR) and Enzyme-linked immunosorbent assay (ELISA) validation, were performed to elucidate microbial, genetic and metabolic responses. Growth performance, including the specific growth rate (SGR) and weight gain rate (WGR), was concurrently assessed. NP exposure significantly suppressed WGR and SGR, and induced gut microbiota dysbiosis alongside and lipid metabolism disorders in S. meridionalis. Probiotic pretreatment effectively reversed these toxic effects and restored the inhibited WGR and SGR. Multiomics integration revealed that the protective effects of probiotics were mediated by a coherent \"microbe-host\" co-metabolism network across 3 progressive layers: (1) Microbial Remodelling: in which beneficial taxa (e.g., Bacteroides eggerthii and Cetobacterium sp.) were enriched, and the functional capacity for short-chain fatty acid (SCFA) synthesis and ethanolamine metabolism was enhanced; (2) Host Gene Regulation: in which key lipid metabolism genes (ek1, cept1, ept1, mogat2, and abcg2a) were upregulated, and lipase activity was restored; and (3) Metabolic Pathway Activation and Physiological Repair: in which the activity of the NP-suppressed Kennedy pathway was reactivated, thereby promoting phosphatidylethanolamine (PE) and phosphatidylcholine (PC) synthesis and ultimately restoring gut barrier function. These results were further were corroborated by RT‒qPCR and ELISA. This study systematically elucidated that probiotics alleviated NP toxicity by remodelling a \"microbiota-host Kennedy pathway gene-metabolite (PE and PC)-growth performance\" regulatory network. The key mechanism is the beneficial microbiota activating the host Kennedy pathway and restoring gut phospholipid homeostasis and barrier function. These findings provide a theoretical basis for developing targeted, lipid metabolism focused probiotic feed additives for use in sustainable aquaculture.","42421035":"ID: 42421035\nTitle: The impact of synbiotic yogurt consumption on insulin-resistance surrogates, atherogenic and novel anthropometric indices in adults with metabolic syndrome: a randomized clinical trial.\nAbstract: Metabolic syndrome (MetS) represents a well-recognized contributor to cardiovascular risk, and synbiotics have recently gained attention as a potential dietary strategy for its management. The present study aimed to determine whether a novel synbiotic yogurt formulated with Lactobacillus plantarum, Lactobacillus pentosus, and the yeast Kluyveromyces marxianus affects atherogenic markers, cardiometabolic parameters, and insulin resistance surrogates in individuals among individuals diagnosed with MetS. A 12-week double-blind, standard-yogurt-controlled randomized clinical trial was conducted, enrolling 44 adults with MetS who were randomized to either 300 g/day of synbiotic yogurt (n = 22) or a matched control yogurt (n = 22); 41 (22 synbiotic, 19 control yogurt) completed and were analyzed. A comprehensive panel of cardiometabolic outcomes was evaluated at baseline and week 12, encompassing atherogenic indices including the Atherogenic Index of Plasma (AIP), Castelli's Risk Index-I (CRI-I), Castelli's Risk Index-II (CRI-II), Atherogenic Coefficient (AC), and oxidized low-density lipoprotein (ox-LDL); cardiometabolic measures including the Visceral Adiposity Index (VAI), Waist Triglyceride Index (WTI), and Cardiometabolic Index (CMI); body shape and adiposity indices including A Body Shape Index (ABSI), Body Roundness Index (BRI), Body Adiposity Index (BAI), Conicity Index, Abdominal Volume Index (AVI), and Weight-adjusted Waist Index (WWI); and surrogate markers of insulin resistance including the Triglyceride-Glucose Index (TyG), Hepatic Steatosis Index (HSI), triglyceride to high-density lipoprotein ratio (TG/HDL), TyG-Body Mass Index (TyG-BMI), TyG-Waist Circumference (TyG-WC), Metabolic Score for Insulin Resistance (METS-IR), and Lipid Accumulation Product (LAP). At the end of the 12-week period, statistically significant between-group differences were limited to four indices, namely CRI-I (p = 0.039), CRI-II (p = 0.038), AC (p = 0.039), and BAI (p = 0.027), all of which favored the control group. Within-group analyses indicated that the control arm experienced significant reductions in AIP, CRI-I, CRI-II, AC, TG/HDL, and METS-IR, whereas participants in the synbiotic arm demonstrated significant decreases only in TyG and TyG-BMI. No significant changes were observed in other indices. According to our findings, 12 weeks of daily synbiotic yogurt consumption did not significantly improve insulin resistance surrogates, atherogenic, and novel anthropometric indices in adults with MetS.

By inhibiting the gastric H⁺/K⁺-ATPase, PPIs suppress acid secretion and impair bacterial killing, thereby promoting gut dysbiosis that disrupts barrier integrity and enhances bacterial translocation, ultimately exacerbating liver injury. PPIs are frequently co-administered with antibiotics for indications such as gastrointestinal bleeding, Spontaneous Bacterial Peritonitis (SBP), other infections, or hepatic encephalopathy prophylaxis, but the consequences of this combined therapy on gut microbial ecology and disease outcomes remain unclear. Our study addresses this gap by showing how PPI use, alone or with antibiotics, reshapes the gut microbiome and aggravates liver disease progression. In previous studies, we showed that PPIs promote dysbiosis and ALD progression in mice and humans by facilitating intestinal expansion and hepatic translocation of Gram-positive Enterococcus. Fecal cytolysin, an Enterococcus faecalis exotoxin that induces hepatocyte death, predicts mortality in patients with alcohol-associated hepatitis (AH). In this study, we have examined the mechanism by which PPIs alone and in combination with non-absorbable antibiotics targeting Gram-positive bacteria influence ALD, as well as the disease mechanisms associated with cytolytic Enterococcus faecalis and the development of therapeutic strategies. In mice, alcohol administration during gastric acid suppression promoted expansion of Gram-positive taxa, including cytolysin-producing Enterococcus. Similarly, PPI use in patients with AH was associated with increased fecal Enterococcus and higher 30-d mortality, underscoring the translational relevance of our findings. Unexpectedly, treatment of acid-suppressed mice with non-absorbable antibiotics designed to suppress Gram-positive bacteria worsened ethanol-induced steatohepatitis: while Enterococcus abundance decreased, Streptococcus and other potentially pathogenic taxa expanded, leading to increased bacterial translocation and aggravated liver injury. In patients with cirrhosis or metabolic dysfunction-associated steatotic liver disease (MASLD), PPIs did not promote Enterococcus expansion, indicating etiology-dependent microbiome responses. Finally, we identified dipalmitoylphosphatidylcholine and Caspase-1 inhibitor as in vitro and in vivo modulators of cytolysin activity, highlighting potential therapeutic avenues. Collectively, our study demonstrates how PPIs and non-absorbable antibiotics targeting Gram-positive bacteria interact with the gut microbiome to drive ALD, underscoring the need for careful therapeutic management.","42421220":"ID: 42421220\nTitle: Discovery of Novel Isoxazole-Based FXR Agonists Containing a 1,2,4-Oxadiazol-5(4H)-one Ring.\nAbstract: Farnesoid X receptor (FXR) is a member of the ″metabolic″ subfamily of nuclear receptors and is mainly present in the liver and intestines, playing a crucial role in bile acid homeostasis, inflammation, and fibrosis. Activation of FXR has emerged as a promising therapeutic strategy for treating metabolic dysfunction-associated steatohepatitis (MASH) or other FXR-dependent diseases. Here, we report our work on the discovery of a series of isoxazole-based FXR agonists containing an oxadiazolone ring. 40 compounds were designed and synthesized based on scaffold hopping and bioisostere strategies. In particular, compound 34 (Linafexor) is a potent FXR agonist with favorable pharmacokinetic properties, high liver distribution, and ideal in vivo efficacy. It has completed Phase II clinical trial for patients with MASH and is currently undergoing a Phase III clinical trial for patients with primary biliary cholangitis (PBC).

Mitophagy, as a selective autophagy, is reported to be involved in the regulation of liver injury. Sinensetin, a polymethoxylated flavonoid abundant in citrus fruit peels, exhibits various biological activities, including anti-inflammatory and hepatoprotective properties. However, whether sinensetin can target mitophagy and protect against HFD-induced liver damage via the gut-liver axis remains inadequately explored. In order to further investigate the relationships involved, we conducted histopathology analysis, biochemical analysis, 16S rRNA sequencing, and short-chain fatty acid (SCFA) levels. Sinensetin administration ameliorated hepatic steatosis, inflammation, and restored intestinal integrity in HFD-fed mice. Mechanistically, sinensetin remodeled the gut microbiota, elevating SCFA levels, which activated mitophagy and cleared damaged mitochondria in liver and intestinal tissues, thereby suppressing the toll-like receptor 4 (TLR4)/mitogen-activated protein kinase (MAPK) signaling. Sinensetin may contribute to protecting against HFD-induced liver injury and intestinal barrier dysfunction by orchestrating the integrated \"microbiota-SCFA-mitophagy\" defensive network, providing a novel paradigm beyond the classical TLR4/MAPK axis.","42421964":"ID: 42421964\nTitle: SARS-CoV-2-infected adipocytes drive adipose inflammation and hepatocyte lipid accumulation.\nAbstract: Obesity and fatty liver may worsen COVID-19 outcomes, but the mechanism by which adipose tissue infection contributes to liver injury is unclear. We aimed to determine whether SARS-CoV-2 infection of human adipocytes promotes inflammation and hepatic lipid accumulation, and to identify the underlying mechanisms. Mesenchymal stem cell-derived human adipocytes were infected with Wuhan SARS-CoV-2 strain. Cell-surface ACE2 expression was measured in adipocytes. Viral replication and infectious titers were measured, and adipocyte morphology, cytokine/adipokine secretion, and lipid metabolism gene expression were analyzed. Culture supernatants from infected adipocytes were then applied to Huh7.5 hepatocytes to evaluate steatosis and fibrogenic activation. SARS-CoV-2 productively infected adipocytes, which express cell-surface ACE2, leading to hypertrophy, increased IL-6 secretion, a higher leptin/adiponectin ratio, and lipid droplet accumulation. The infectious virus was released into the supernatants. However, neutralization with anti-Spike antibodies or UV-C inactivation abolished this effect, indicating that hepatocyte lipid accumulation depended on infectious virus rather than on soluble adipocyte-derived mediators alone. Adipose tissue can serve as a source of infectious SARS-CoV-2 that promotes hepatic steatosis and fibrogenic activation, suggesting a mechanism by which obesity and fatty liver may worsen COVID-19 outcomes, although the contribution of residual infectious virus versus adipocyte-derived factors cannot be fully distinguished. At present, the data do not support an independent role for adipocyte-derived soluble mediators in this effect. The study is intended as a mechanistic in vitro analysis of adipocyte-hepatocyte crosstalk during SARS-CoV-2 infection.","42422421":"ID: 42422421\nTitle: Case Report: Dramatic metabolic improvement with tirzepatide in a patient with acquired partial lipodystrophy following hematopoietic stem cell transplantation.\nAbstract: Acquired lipodystrophy is a rare disorder characterized by adipose tissue loss or dysfunction and is frequently associated with severe insulin resistance and metabolic complications. Metabolic complications of lipodystrophy have occasionally been reported after hematopoietic stem cell transplantation (HSCT), but their clinical features and optimal treatment strategies remain poorly defined. Tirzepatide, a dual agonist of the glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors, has recently emerged as a novel therapy for type 2 diabetes. We report a 37-year-old woman who underwent allogeneic HSCT at 12 years of age for relapsed acute lymphoblastic leukemia after a conditioning regimen including total body irradiation (TBI), high-dose cytarabine, and melphalan. She subsequently developed diabetes mellitus and fatty liver disease at 17 years of age. Although no apparent fat loss was initially recognized, lipodystrophy was clinically suspected based on severe insulin resistance and metabolic abnormalities disproportionate to her body habitus. Computed tomography at 37 years of age revealed region-specific fat loss extending from the lower back to the gluteal region. Glycemic control remained inadequate despite high-dose insulin therapy and sequential treatment with several GLP-1 receptor agonists. After initiation of tirzepatide, glycemic control improved dramatically, allowing complete discontinuation of insulin therapy. Body weight decreased modestly and hepatic steatosis improved. The high-molecular-weight (HMW)/total adiponectin ratio after treatment was elevated (64.0%), suggesting possible improvement in adipocyte secretory function. This case highlights acquired partial lipodystrophy developing after HSCT, supported by region-specific fat loss and characteristic metabolic abnormalities, and demonstrates a marked therapeutic response to tirzepatide. Dual incretin receptor agonism may represent a promising therapeutic strategy for severe insulin resistance associated with adipose tissue dysfunction, potentially through both weight-dependent and weight-independent mechanisms.","42422741":"ID: 42422741\nTitle: Akkermansia muciniphila in cardiovascular diseases: opportunities and challenges.\nAbstract: Cardiovascular disease (CVD) is one of the leading causes of death worldwide and poses a severe threat to human health. Recent years have witnessed a growing interest in how the gut microbiota regulates the cardiovascular system. Akkermansia muciniphila (A. muciniphila), a key constituent of this community, has become a focus of research on CVD prevention owing to its critical role in maintaining gut homeostasis, modulating metabolism, and regulating immunity. This review details the beneficial effects and mechanisms of action of A. muciniphila in CVD. A. muciniphila protects against conditions such as hypertension, atherosclerosis, heart failure, and abdominal aortic aneurysm by repairing the gut barrier, balancing glucose and lipid metabolism, regulating immune-inflammatory responses, and producing protective metabolites such as short-chain fatty acids. However, in pathological states, such as a damaged gut barrier or low-fiber diets, A. muciniphila can over-proliferate, accelerate mucus breakdown, and exacerbate inflammation and disease progression-revealing a \"double-edged sword\" character. Furthermore, diet, medications, and an individual's baseline gut microbiota directly modulate their abundance, underscoring the need for personalized approaches. Future studies should focus on clarifying strain differences, establishing safe dosing, and optimizing delivery systems to advance the clinical application of A. muciniphila in CVD therapy.","42422752":"ID: 42422752\nTitle: Shaping postoperative outcomes: microbiota-modifying dietary fiber interventions in colorectal cancer treatment.\nAbstract: The gut microbiota plays a key role in intestinal homeostasis by reinforcing the gut barrier and modulating inflammation. Gut barrier dysfunction or dysregulated inflammatory response in patients with colorectal cancer may lead to an increased risk of surgical complications associated with poor intestinal healing. Microbiota-modifying dietary interventions have the ability to shift microbial community structures and bacterial metabolite production, with profound implications for host health. This review focuses on the potential for short-term, preoperative, dietary fiber interventions in improving colorectal cancer surgical and oncological outcomes. Additionally, this review highlights important considerations for the optimization and personalization of dietary fiber interventions, notably individual- and fiber-specific microbiota responses.","42422874":"ID: 42422874\nTitle: The role of gut microbiota dysbiosis in the pathogenesis of hyperuricemic nephropathy.\nAbstract: Hyperuricemic nephropathy (HN) is a renal complication associated with sustained hyperuricemia and urate-related renal injury. Emerging evidence suggests that gut microbiota dysbiosis may participate in HN pathogenesis by influencing uric acid metabolism, intestinal urate excretion, gut barrier integrity, microbial metabolite production, and gut-kidney immune crosstalk. However, the strength of evidence varies substantially across proposed mechanisms, with many findings derived from animal models, in vitro experiments, CKD studies, or human studies of hyperuricemia and gout rather than HN-specific clinical cohorts. This review summarizes current clinical and experimental evidence linking gut microbiota dysbiosis with HUA, gout, CKD, and HN, critically evaluates proposed mechanistic pathways, and discusses microbiota-targeted interventions including probiotics, prebiotics, dietary strategies, fecal microbiota transplantation, and metabolite-based approaches. Particular emphasis is placed on distinguishing association from causality and identifying translational gaps that should be addressed in future HN-specific studies.","42423000":"ID: 42423000\nTitle: Exploring the Mechanisms of the Yueju Pill for ALD by Integrating UPLC-QE Orbitrap-MS/MS, Network Pharmacology, and Experimental Verification.\nAbstract: This study integrated UPLC-QE Orbitrap-MS/MS, network pharmacology, and experimental validation to investigate the chemical profile and therapeutic mechanisms of the Yueju pill (YJP) in the treatment of alcoholic liver disease (ALD). Chemical analysis identified 91 compounds in the YJP. After SwissADME screening, 45 active ingredients were predicted as potential bioactive compounds. By overlapping the targets of these compounds with ALD-related targets, a \"component-target-disease\" network was constructed, revealing 183 common targets. Enrichment analysis indicated that YJP exerts its therapeutic effects through multiple pathways, including the HIF-1 signaling pathway. In animal experiments, an ALD mouse model was established using the Lieber-DeCarli ethanol liquid diet. YJP intervention significantly reduced serum TG, AST, and ALT levels, alleviated hepatic lipid deposition and collagen deposition, improved liver mitochondrial homeostasis, and decreased hepatic HIF-1α expression. Moreover, the YJP improved intestinal barrier integrity and upregulated intestinal HIF-1α and occludin expression, reflecting a therapeutic mechanism involving coordinated regulation of the gut-liver axis.","42423485":"ID: 42423485\nTitle: The Role of Gut Microbiota in Liver Regeneration After Partial Hepatectomy: New Evidence From Animal and Human Studies.\nAbstract: Liver regeneration is increasingly recognized as a process influenced not only by hepatocellular signaling but also by the gut-liver axis, where gut microbiota-derived metabolites, immune mediators, and extracellular vesicles modulate hepatic recovery after liver damage. In this review, we explore recent progress in understanding the gut microbiota's role in liver regeneration and discuss its therapeutic potential in the context of hepatic surgery and liver transplantation. Emerging evidence shows that beneficial microbial taxa, including Akkermansia muciniphila, Bifidobacterium longum, and Parabacteroides distasonis, enhance liver regeneration by regulating short-chain fatty acid production, bile acid metabolism, and tricarboxylic acid cycle pathways, while dysbiosis and microbial translocation can impair regenerative outcomes. Key host-microbiome interactions, particularly the Farnesoid X Receptor (FXR)-Fibroblast Growth Factor 19 (FGF19) signaling axis, play a central role in protecting hepatocytes from bile acid overload and supporting regeneration, highlighting the therapeutic potential of FXR agonists, FGF19 mimetics, probiotics, dietary interventions, and metabolite supplementation. At the same time, monitoring bile acids profiles alongside gut microbiota composition may allow early detection and prevention of complications. In addition, microbial-derived markers such as the lipopolysaccharide/lipoteichoic acid ratio may serve as predictive biomarkers for post-hepatectomy liver failure. Adjunctive approaches, including vitamin D supplementation, may further support regeneration through vitamin D receptor-mediated regulation of bile acid homeostasis and cell-cycle progression. In the context of live donor liver transplantation, the detection of occult bacteremia further underscores the complexity of host-microbiome interactions and suggests that microbiological surveillance could improve postoperative management. Collectively, these findings emphasize the importance of microbiota-targeted strategies to improve hepatic regeneration, reduce postoperative complications, and optimize outcomes following liver surgery and transplantation.","42424108":"ID: 42424108\nTitle: Markers of compromised gut epithelial barrier integrity increase during the menopause transition.\nAbstract: In female murine models, one source of inflammation is a menopause-related increase in gut permeability. We examined whether the menopause transition (MT) in women is associated with an increase in markers of gut epithelial dysfunction and gut microbial product translocation, signals of compromised gut epithelial barrier integrity. In 964 women, we measured markers of gut epithelial dysfunction (fatty acid binding protein 2, FABP2) and gut microbial antigen translocation (soluble CD14, sCD14) using sera collected before, during and after the MT. Multivariable mixed effects regressions fit piece-wise linear models to repeated FABP2 or sCD14 measures relative to time from final menstrual period (FMP). Covariates were age at FMP, race/ethnicity, and BMI. FABP2 and sCD14 did not change significantly until 2.5 years pre-FMP. At that point, FABP2 began rising; sCD14 began increasing 6 months later. FABP2 and sCD14 peaked 6 and 6.5 years post-FMP, respectively; subsequent levels remained stable. During the ~9-year interval of MT-related gain in gut barrier compromise markers, annual FABP2 and sCD14 increases were 2.6% (95% CI: 1.7 to 3.4%) and 0.8% (95% CI: 0.6 to 1.1%), respectively, among white women with sample-average BMI and age at FMP. FABP2 and sCD14 change rates did not differ significantly by race/ethnicity, BMI, or age at FMP. The MT is associated with a rise in markers of compromised gut barrier integrity, suggesting that this pathway of inflammation, previously described in animal models, occurs in humans.

Evidence links gut-brain axis dysfunction and metabolic disturbances to AD. Although cannabidiol (CBD) has neuroprotective effects, its use is limited by poor bioavailability and brain delivery. Arginylglycylaspartic acid (RGD)-functionalized, CBD-loaded lipid nanoparticles (CBD/LNP-RGD) were developed to enhance targeted delivery across the blood-brain barrier (BBB) via integrin αvβ3-mediated transcytosis. Cellular uptake and BBB permeability were evaluated in vitro. Anti-inflammatory and antioxidant effects were assessed in Aβ/LPS-induced models. In vivo efficacy was examined using cognitive-behavioral tests, including the novel object recognition and the Morris water maze. Metabolic parameters, histopathology, synaptic protein expression, and gut barrier integrity were also evaluated. CBD/LNP-RGD demonstrated a 3-fold increase in cellular uptake and a 65% enhancement in BBB transport compared to non-targeted formulations. Treatment significantly reduced pro-inflammatory cytokines (i.e., IL-6 and TNF-α, p < 0.001) and intracellular reactive oxygen species (p < 0.001). In vivo, CBD/LNP-RGD improved cognitive performance comparable to Donepezil (p < 0.001). Additionally, it normalized glycemic control, insulin resistance, and triglyceride levels without hepatic or renal toxicity. At the tissue level, CBD/LNP-RGD reduced Aβ and tau pathology, restored short-chain fatty acids, preserved hippocampal neuronal integrity, and upregulated synaptophysin and PSD-95 proteins. Enhanced intestinal barrier function was evidenced by increased expression of tight junction proteins ZO-1 and occludin. CBD/LNP-RGD represents a multifunctional nanotherapeutic platform that improves brain delivery and exerts neuroprotective, anti-inflammatory, antioxidant, and metabolic regulatory effects. Its ability to modulate both central pathology and the gut-brain axis highlights its potential as a disease-modifying strategy for Alzheimer's disease.","42425686":"ID: 42425686\nTitle: Microbiota-liver axis and host transcriptomic mechanisms underlying the anti-obesity effects of Bifidobacterium animalis DPU-MWFBA in early-life overfeeding.\nAbstract: Early-life nutritional overfeeding is increasingly recognized as a critical driver of metabolic programming and long-term obesity risk. This study investigated the protective effects and underlying mechanisms of Bifidobacterium animalis DPU-MWFBA, designated as FBA-40, against early-life overfeeding-induced obesity and metabolic dysfunction. An early overfeeding mouse model was established by small-litter rearing, followed by a two-week oral intervention with FBA-40. FBA-40 significantly attenuated excessive body weight gain and adiposity, improved glucose tolerance and insulin sensitivity, and alleviated dyslipidemia, systemic inflammation, and hepatic dysfunction. Histological analyses showed that FBA-40 reduced hepatic lipid accumulation and improved liver morphology. In addition, colonic histology and immunohistochemistry demonstrated that FBA-40 preserved intestinal barrier integrity by increasing ZO-1 and Occludin expression while suppressing TNF-α-associated inflammatory activation. Gut microbiota analysis revealed that FBA-40 restored microbial richness and diversity and reshaped gut microbial composition toward a more metabolically favorable profile. Hepatic transcriptomic analysis further showed that FBA-40 reprogrammed lipid metabolism-, oxidative stress-, and inflammation-related pathways, particularly PPAR signaling, linoleic acid metabolism, cholesterol metabolism, bile secretion, and arachidonic acid metabolism. qRT-PCR and estern blot validation confirmed that FBA-40 suppressed lipogenesis-related targets, including Scd1, Acaca, Lpin1, and SCD1, while restoring PPARα/EHHADH-associated fatty acid β-oxidation and GPX1-mediated antioxidant defense. Collectively, these findings demonstrate that FBA-40 alleviates early-life overfeeding-induced metabolic dysfunction by coordinating gut microbial remodeling, intestinal barrier protection, and hepatic lipid metabolic reprogramming. This study provides mechanistic evidence supporting FBA-40 as a promising early-life probiotic candidate for preventing obesity and associated metabolic disorders.","42425839":"ID: 42425839\nTitle: Right colon volvulus causing acute bowel obtruction.\nAbstract: ","42425970":"ID: 42425970\nTitle: Maternal cold exposure improves offspring metabolic health via a milk lithocholic acid-microbiota-Th17 axis.\nAbstract: Metabolic diseases are rising with a trend toward earlier onset, yet effective preventive strategies remain limited. While cold exposure improves metabolic health in adults, its role during pregnancy in shaping offspring metabolic outcomes remains unknown. Herein, we demonstrate that maternal cold exposure in early pregnancy markedly improved offspring glucose tolerance, insulin sensitivity, and hepatic lipid metabolism when challenged with a Western diet, and the benefits persisted into late adulthood. Transcriptomic and immunophenotyping analyses revealed that offspring with cold-exposed dams exhibited suppressed Th17 activity and IL-17 signaling. Cross-fostering and metabolomics identified elevated lithocholic acid (LCA) in maternal milk as a critical mediator of these effects. LCA supplementation recapitulates these benefits through gut microbiota-dependent conversion to 3-oxo-LCA. Furthermore, Clostridium scindens supplementation enhanced 3-oxo-LCA production, suppressed Th17 responses, and alleviated diet-induced hepatic steatosis. Clinically, analysis of the UK Biobank cohort showed that winter conception was associated with a lower risk of metabolic dysfunction-associated steatotic liver disease in offspring. A similar association was observed in the CHARLS cohort in colder northern China. Together, these results identify a maternal cold-microbiota-bile acid-Th17 axis that programs offspring metabolic health and highlight microbial bile acid metabolism as a potential therapeutic target for metabolic diseases.","42426489":"ID: 42426489\nTitle: Effect of Probiotics on the Gut-Mammary Pathway: Implications on Infant Microbiota Transfer and Development.\nAbstract: Transfer of microbiota from the maternal gut, during lactation, takes place via breastmilk, which establishes an intricate beneficial microbial ecosystem in the gut of the newborn. A healthy gut microbiota influences and enhances the neonatal health, and aids in multidimensional development-metabolically, immunologically, neurologically, and hormonally. Several microorganisms like Lactobacillus and Bifidobacterium get transferred to the infant gut and play a key role in its colonization and programming. Administration of such microbes, or probiotics, to the mother can assist in improving the benefits imparted by breastmilk to the infant, and can also provide health benefits to the mother. In recent years, there has been a focus on related metagenomic studies and the immunological effects of individual genera have also been studied in detail. In this review, we observe the gut-mammary pathway and the different roles played by probiotics in prenatal and postnatal scenarios. We also analyze the level of evidence of potential of some promising probiotic strains in the transfer, establishment, and development of infant gut microbiota based on recently conducted studies. The analysis of recent metagenomic studies proved that strains like Bifidobacterium infantis, Lactobacillus rhamnosus, and Limosilactobacillus reuteri exibit a high level of evidence in benefitting the microbiota transfer as well as establishment, diversification, and development of the infant gut ecosystem. Hence, these strains in particular, can be given as supplements to mothers during pregnancy and lactation, in order to improve their inherent immunity and the overall health of the mother-infant dyad. With the advent of metagenomics, the roles, functions and effects of microbes in the gut-mammary pathway have been re-examined. This review, critically evaluates the recent studies related to gut-mammary pathway and the different roles played by probiotics in prenatal and postnatal scenarios with particular emphasis on the strength and quality of their evidence.","42426884":"ID: 42426884\nTitle: Multi-omics and functional validation reveal that Methanobrevibacter-derived L-3-aminoisobutyrate alleviates subclinical mastitis in dairy goats via the HSPA1B-p65 signaling pathway.\nAbstract: Subclinical mastitis (SCM) is prevalent in dairy livestock and compromises milk quality and lactation performance. Although often attributed to bacterial infection, many cases lack identifiable pathogens, suggesting alternative mechanisms. While evidence supports a gut-mammary gland axis, the microbial drivers and microbiota-derived metabolites linking gut dysbiosis to SCM remain unclear. Here, we aimed to identify SCM-associated gut microbial markers, prioritize candidate therapeutic metabolites and define the underlying mechanism. Based on differences in somatic cell count (SCC) and inflammatory phenotypes across a cohort of 167 mid-lactation Saanen dairy goats, we selected 6 healthy and 6 SCM goats for downstream analyses. By integrating metagenomics, metabolomics, cross-species fecal microbiota transplantation (FMT) and functional validation in vitro and in vivo, we found that SCM was accompanied by reduced milk yield and heightened inflammatory signatures. Compared with the Healthy group, SCM goats exhibited marked remodelling of the gut microbiota, with enrichment of opportunistic taxa (Eubacterium and Blautia) and a pronounced depletion of archaeal Methanobrevibacter spp. Notably, FMT from SCM donors recapitulated mammary inflammatory phenotypes in mice, supporting a causal contribution of gut dysbiosis to mammary inflammation. Joint metagenomic functional profiling and metabolomics further identified the branched-chain amino-acid-derived metabolite L-3-aminoisobutyrate (BAIBA) as significantly enriched in the gut of healthy goats. Moreover, Methanobrevibacter spp. harboured key enzyme genes (vorA, vorB and vorD) implicated in BAIBA biosynthesis. In an LPS-challenged MAC-T model, BAIBA attenuated mammary epithelial inflammation by activating endoplasmic reticulum protein quality control programmes and restoring HSPA1B expression, thereby suppressing NF-κB activation and reducing pro-inflammatory cytokine production. Finally, in naturally infected goats, intramammary administration of BAIBA lowered SCC, highlighting translational potential. This study identifies BAIBA as a microbiota-derived metabolite that protects against SCM by restraining mammary inflammation via the HSPA1B-NF-κB axis, establishing a mechanistic gut-mammary link and highlighting a potential non-antibiotic intervention strategy.

However, their genetic tractability and genetic tools remain limited, hindering functional microbiome research and synthetic biology applications. In this study, we expanded the genetic toolbox for the widely used probiotic strains, L. rhamnosus GR-1 and L. rhamnosus GG, by implementing direct plasmid cloning and testing of a set of genetic elements earlier validated in Lactiplantibacillus plantarum. Among five constitutive promoters (PtlpA, Ptec, Pcpg, P48 and P23), PtlpA showed strong promoter activity in L. rhamnosus GR-1. We further characterized this promoter's functionality by incorporating a repressor and assessing its native thermo-responsiveness and stability over time, enhancing its potential for industrial applications. Using these tools, we engineered L. rhamnosus GR-1 with constitutive fluorescence of mCherry, mScarlet3 and sfGFP. The functionality of these fluorescent L. rhamnosus GR-1 strains was shown in a proof-of-concept growth competition experiment with a fluorescent pathogenic Staphylococcus aureus strain. These constitutively fluorescent L. rhamnosus strains, along with the expanded genetic toolkit, offer valuable resources for studying functional properties, such as adhesion, microbe-microbe and host-microbe interactions, and advancing Lactobacillaceae as a chassis for synthetic biology.","42427128":"ID: 42427128\nTitle: Targeting ferroptosis with chenodeoxycholic acid improves residual cardiac dysfunction after surgical ventricular reconstruction.\nAbstract: Surgical ventricular reconstruction (SVR) partially reverses left ventricular remodelling in postinfarction heart failure, yet residual cardiac dysfunction persists through unknown mechanisms. We investigated ferroptosis involvement in post-SVR pathology and explored pharmacological interventions. Myocardial infarction (MI) was induced in C57BL/6 mice followed by SVR at 4 weeks. Cardiac function was assessed by echocardiography and pressure-volume catheterization. Ferroptosis biomarkers were quantified. Connectivity Map analysis identified candidate compounds validated in Erastin-challenged AC16 cardiomyocytes and SVR mouse models. Compared with MI group, SVR improved the left ventricular end-diastolic volume index by 36.8% but showed persistent iron overload, glutathione depletion and elevated malondialdehyde. Transcriptomic analysis identified 90 ferroptosis-related differentially expressed genes following SVR. Connectivity Map prioritized three ferroptosis inhibitors, and chenodeoxycholic acid (CDCA) exhibited superior efficacy. Farnesoid X receptor (FXR) knockdown in AC16 cardiomyocytes exacerbated erastin-induced ferroptosis, while CDCA co-treatment significantly reduced erastin-induced ROS production, upregulated glutathione peroxidase 4 (GPX4) expression, and restored superoxide dismutase activity, rescued the ferroptotic phenotype and reversed associated molecular changes in FXR-knockdown cells. In SVR-treated mice, 3-week CDCA administration (50 mg·kg-1·day-1) reduced myocardial iron deposition by 14.8%, improved left ventricular ejection fraction from 23.73% to 31.61% and restored GSH/GSSG ratio from 1.645 to 1.988. CDCA up-regulated GPX4 expression by 1.573-fold compared with the vehicle group. SVR paradoxically exacerbates ferroptosis in residual myocardium through iron dysregulation and antioxidant depletion. CDCA, a primary bile acid activating FXR signalling, is a novel pharmacological strategy to mitigate post-SVR ferroptosis and improve cardiac outcomes.","42427207":"ID: 42427207\nTitle: Cyclocarya paliurus Polysaccharides Attenuate High-Fat Diet-Induced Metabolic Dysfunction via Gut Microbiota Remodeling.\nAbstract: Alterations in gut microbiota composition are closely associated with obesity and metabolic disorders. Cyclocarya paliurus polysaccharides (CCPP) have been shown to improve lipid metabolism and modulate the gut microbiota; however, mechanistic evidence remains limited and may vary depending on preparation methods. This study investigated whether a crude polysaccharide-enriched Cyclocarya paliurus preparation alleviates high-fat diet-induced metabolic dysfunction and is associated with gut microbiota remodeling. Male C57BL/6 J mice were randomized into three groups: normal diet (ND), high-fat diet (HFD), and HFD supplemented with CCPP for 12 weeks. Serum metabolic parameters were measured; intestinal inflammatory cytokine transcripts were assessed by qRT-PCR; and cecal microbiota composition was analyzed by 16S rRNA gene sequencing. Additionally, fecal microbiota transplantation (FMT) was performed by transferring microbiota from CCPP-treated donors to antibiotic-pretreated HFD-induced recipients for 8 weeks. CCPP attenuated HFD-induced body weight gain and reduced subcutaneous and visceral adipose tissue mass. CCPP significantly improved serum total cholesterol and low-density lipoprotein cholesterol (LDL-C) and reduced fasting glucose. Cecal 16S rRNA gene profiling showed that CCPP reshaped the gut dysbiosis associated with a HFD and enriched microbial taxa that are commonly linked to carbohydrate fermentation. These taxa specifically include Lachnospiraceae-related microbial taxa and Ileibacterium. Importantly, FMT from CCPP-treated donors recapitulated these metabolic improvements, confirming that the benefits of CCPP were microbiota-dependent. CCPP mitigates obesity and metabolic dysfunction by remodeling the gut microbiota, particularly by enriching short-chain fatty acid-producing taxa. These findings highlight CCPP as a potential microbiota-targeted therapeutic agent for metabolic disorders.","42427432":"ID: 42427432\nTitle: Toward a Dual-Axis Model of Microbiome Modulation in Cancer Immunotherapy: Pathobiont Elimination and Functional Ecosystem Restoration.\nAbstract: The gut microbiome is increasingly recognized as a modulator of cancer immunotherapy efficacy, including responses to immune checkpoint inhibitors (ICIs) and chimeric antigen receptor T-cell (CAR-T) therapy. Recent clinical trials of microbiome-targeted interventions such as fecal microbiome transplantation (FMT) and live biotherapeutic products (LBPs) suggest the potential to enhance antitumor immunity and improve clinical outcomes. Yet responses remain heterogeneous and are not fully explained by engraftment of donor taxa alone. We integrate evidence from interventional trials, observational cohort studies, and principles from gut microbial ecology to develop a model hypothesis on how microbiome-targeted therapies may shape response to immunotherapy, with potential to inform future trial design, analyses, and interpretation. Drawing on the available evidence, we propose that therapeutic perturbation of the gut microbiome may augment immunotherapy efficacy through two parallel axes: (1) elimination of immunosuppressive pathobionts that restrain CD8+ T-cell activation and promote myeloid-mediated immunosuppression, and (2) functional restoration of the gut ecosystem through engraftment of taxa that provide metabolites, structural cues, and immunoregulatory signals required for effective antitumor immunity. The success of both axes appears to depend on ecological processes governed by predator-prey dynamics, including colonization resistance, resilience of the resident microbiota, and the ability of administered organisms to displace entrenched dysbiotic communities. This ecological lens may help to explain discrepancies across trial designs, donor types, and intervention modalities, and suggests that complete donor engraftment is neither necessary nor sufficient for clinical benefit. A dual-mechanism model of pathobiont elimination and functional microbial restoration may help explain microbiome-mediated enhancement of cancer immunotherapy, highlighting a balanced immune permissive gut ecosystem as a key determinant of therapeutic success.","42427618":"ID: 42427618\nTitle: Preserved Barrier Integrity and Altered Immune Profiles in Chronic Cannabis Users: Potential Roles of Δ9-Tetrahydrocannabinol.\nAbstract: Although cannabinoids such as delta-9-tetrahydrocannabinol (THC) are generally immunosuppressive in preclinical models, chronic cannabis use in humans is paradoxically associated with increased infection risk and systemic inflammation. In this study, we demonstrate that THC directly strengthens intestinal epithelial barrier function in vitro by increasing trans-epithelial electrical resistance in a concentration-dependent manner in Caco-2 monolayers. In a cross-sectional study of chronic cannabis users via smoking or snorting compared with non-using controls, plasma lipopolysaccharide (LPS), and microbial translocation-driven inflammatory cytokines (IL-23, MCP-1, IL-8) were significantly reduced, while some cytokines (IL-6, IL-1β, TNF-α, IL-10) remained unchanged. Concurrently, users exhibited elevated macrophage-derived chemokine (MDC) and homeostatic cytokines IL-15 and IL-21, markedly suppressed IL-7 and IL-4. Plasma IL-15 and MDC levels correlated with consumption intensity, and IL-23, IL-7, and IP-10 correlated with age of first use or during heaviest use. These findings suggest that habitual cannabis use may protect gut barrier integrity and reduce microbial translocation and associated inflammation, while simultaneously disrupting systemic immune homeostasis through selective cytokine dysregulation. This dual, dose-dependent immunomodulatory profile highlights the complex balance between potential benefits and risks in both recreational and therapeutic cannabis use.","42428305":"ID: 42428305\nTitle: Prunella vulgaris polyphenols mediate the gut-liver axis to improve MASLD: regulating cholesterol metabolism and gut microbiota.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most prevalent chronic liver disease worldwide. The latest research shows that its pathogenesis is closely related to the imbalance of gut microbiota. Prunella vulgaris L. is an edible-medicinal plant containing bioactive compounds such as polyphenols that can lower cholesterol and protect the liver. However, whether it has anti MASLD effects has not been reported. The present study aimed to investigate the effect of Prunella vulgaris polyphenols (PVP) on alleviating MASLD from the perspective of the gut-liver axis. PVP composition was characterized via UPLC-MS/MS and HPLC. Enzymatic kinetics, fluorescence quenching, and molecular docking were used to study the inhibition of PVP and rosmarinic acid (RA) on cholesterol esterase (CEase). Effects on liver lipid accumulation and intestinal cholesterol transport were assessed using HepG2 and Caco-2 cell models. A MASLD mouse model was evaluated through ELISA, tissue staining, and 16S rRNA sequencing to determine the efficacy and mechanisms. PVP and RA exhibited anti-competitive inhibition of CEase, with IC50 values of 1.63 ± 0.06 and 0.39 ± 0.17 mg/mL, respectively. RA showed strong binding to CEase. PVP and RA significantly alleviated hepatic lipid accumulation in HepG2 cells, inhibited intestinal cholesterol absorption, and promoted cholesterol efflux in Caco-2 monolayers. In MASLD mice, PVP significantly reduced serum ALT, TBA, and TG, lowered hepatic TC and fecal TBA (P < 0.05), and ameliorated liver pathological damage. In addition, both PVP and RA modified the composition of gut microbiota in the cecum, which characterized by a reduction in bile acid (BA)-related bacteria such as g_UBA7173, g_Bacteroides_H, f_Burkholderiaceae_A, g_Phocaeicola_A, and g_Turicimonas, while increasing f_Lachnospiraceae and f_Oscillospiraceae. PVP ameliorates MASLD by inhibiting CEase and intestinal cholesterol absorption, promoting cholesterol efflux, and regulating TBA levels along with intestinal microbiota homeostasis. Our findings suggest that PVP and RA deserve further investigation as potential modulators of cholesterol metabolism in MASLD.","42428309":"ID: 42428309\nTitle: Translating priority effects and niche engineering into rational microbiome therapeutics across the gut-lung axis.\nAbstract: The homeostasis of the human microbiome relies on \"colonization resistance\" governed by complex ecological rules. However, severe perturbations such as broad-spectrum antibiotics can dismantle this defense, shifting the microbial community into a \"dysbiotic trap\" driven by pathogen niche construction-an alternative stable state that is notoriously difficult to spontaneously reverse. This ecological mechanism explains the frequent failure of empirical therapies like fecal microbiota transplantation (FMT) and blind probiotic supplementation. Crucially, local ecological collapse triggers systemic cascades via the \"gut-lung axis.\" The depletion of core gut metabolites, such as short-chain fatty acids, impairs the metabolic reprogramming and antimicrobial capacity of distal alveolar macrophages. This cascade drastically increases host susceptibility to respiratory infections. To break this clinical deadlock, microbiome medicine must transition from \"empirical transplantation\" to \"rational microbiome engineering.\" This review systematically outlines the core pillars of this translational framework: achieving \"precision niche clearing\" via targeted bacteriophages; capturing optimal intervention windows to harness \"priority effects\"; and ultimately engrafting \"synthetic microbial consortia\" (SMCs) rationally designed upon metabolic cross-feeding principles. This strategy offers a promising avenue to durably shatter the dysbiotic deadlock and restore host immune homeostasis across the gut and systemic levels.","42428310":"ID: 42428310\nTitle: Advances in understanding intestinal microbiota mechanisms and intervention strategies for anxiety, depression, sleep disorders, and constipation.\nAbstract: Anxiety, depressive symptoms, sleep disorders, and chronic constipation frequently co-occur and collectively impose a substantial clinical burden. Although these conditions may involve partially overlapping neural, endocrine, immune, and metabolic processes, their shared pathophysiological basis has not been fully established. This narrative review examines the potential role of the microbiota-gut-brain axis in linking affective symptoms, sleep disturbances, and chronic constipation. Evidence from human observational studies, Mendelian randomization analyses, animal models, and preliminary interventional studies suggests that alterations in gut microbial composition and function may contribute to these clinical associations through microbial metabolites, immune signaling, neuroendocrine regulation, and neural pathways. The review also summarizes microbiota-targeted interventions, including probiotics, prebiotics, dietary modification, and fecal microbiota transplantation. However, substantial heterogeneity in study populations, microbial findings, experimental methods, and intervention protocols limits causal interpretation and clinical generalization. A more rigorous distinction among associative, mechanistic, genetic, and interventional evidence is therefore required when evaluating the therapeutic potential of microbiota-based strategies.","42428317":"ID: 42428317\nTitle: Herbal medicines modulate gut microbiota in metabolic diseases: a review.\nAbstract: Metabolic diseases-including obesity, type 2 diabetes mellitus (T2DM), and non-alcoholic fatty liver disease (NAFLD)-affect over 1 billion individuals globally and are characterized by insulin resistance, chronic inflammation, and gut microbiota dysbiosis. Herbal medicines offer multi-component therapeutic potential through microbiota modulation, but mechanistic insights remain fragmented. This review synthesizes recent advances in herbal medicine-mediated gut microbiota regulation in metabolic diseases and delineates underlying molecular mechanisms. A comprehensive literature search was conducted across PubMed and Web of Science. Search strategies employed MeSH terms and free-text keywords encompassing herbal medicines, gut microbiota, and metabolic diseases. Two authors performed study selection and data extraction. Evidence synthesis was structured according to intervention type and metabolic disease category. Herbal polysaccharides and other compounds consistently increased beneficial bacteria and promoted short-chain fatty acids (SCFAs) production, improving intestinal barrier integrity via ZO-1/Occludin upregulation and attenuating TLR4/NF-κB-mediated inflammation. Herbal formulations exerted synergistic effects by remodeling microbial community structure, correcting SCFA/bile acid imbalances, and activating IRS1/PI3K/AKT insulin signaling. Notably, Lactobacillus and Akkermansia emerged as recurrent beneficial targets across multiple herbal interventions. However, evidence is predominantly preclinical, and translational validity to humans requires further validation. Herbal medicines ameliorate metabolic diseases through multi-target gut microbiota modulation, involving SCFA production, bile acid metabolism, and inflammatory pathway attenuation. These mechanistic insights support the development of microbiota-targeted herbal therapeutics, though clinical translation necessitates standardized formulations and rigorous human trials.","42428532":"ID: 42428532\nTitle: Ameliorative Effects of Newly Developed Citrus Hybrid \"Mubong\" Peel Extract on Experimental Colitis and Gut Microbiota Dysbiosis.\nAbstract: \"Mubong,\" a newly developed citrus hybrid, is recognized for its unique flavor profile, yet its chemical composition and therapeutic potential remain unexplored. In the present work, we profiled the phytochemical content and antioxidant capacities of \"Mubong\" flesh and peel, then evaluated the anti-inflammatory effects of the \"Mubong\" Peel Extract (MPE) using in vitro (LPS-stimulated RAW 264.7 cells) and in vivo (DSS-induced colitis) models, coupled with microbiota analysis. In vitro anti-inflammatory activity was studied by measuring nitric oxide (NO) production and NF-κB signaling in RAW-Blue cells. In vivo, ICR mice were administered MPE (400 mg/kg) orally during DSS-induced colitis. Disease severity was evaluated through the Disease Activity Index (DAI), colon length, and histological analysis. To characterize microbial and metabolic shifts, we integrated 16S rRNA hypervariable region sequencing with targeted quantification of short-chain fatty acids (SCFAs). MPE was found to be rich in naringin (2730.66 ± 93.90 mg/100 g), neohesperidin (1493.85 ± 82.67 mg/100 g), and d-limonene (69.06%). In vitro, MPE (200-400 μg/mL) significantly inhibited NO production and suppressed NF-κB-dependent transcriptional activity. In mice, MPE treatment was associated with the attenuation of weight loss, reduction of DAI scores, and the mitigation of colon shortening. These clinical improvements were also coincided with a reduction in pro-inflammatory cytokines, specifically TNF-α (~80 to ~52 pg/mL) and IL-6 (~30 to ~3 pg/mL), and restoration of the SCFAs, propionic acid (~35% to ~80%) and butyric acid (~30% to ~50%). Microbiota analysis revealed that MPE treatment correlated with alterations in the gut landscape, specifically the enrichment of obligate anaerobes such as Lachnoclostridium and Acetatifactor. Furthermore, these microbial changes paralleled a recovery trend in short-chain fatty acids (butyrate and propionate) otherwise depleted by DSS. Our findings suggest that MPE exerts anti-inflammatory activity, likely through the modulation of NF-κB/AP-1-dependent transcriptional activity and preservation of gut microbial homeostasis. These preclinical findings suggest that \"Mubong\" warrants further investigation as a potential functional food candidate for the management of ulcerative colitis and related inflammatory disorders.","42429050":"ID: 42429050\nTitle: Protective effects of Astragaloside IV on various liver diseases: From chemistry to herbal medicines (Review).\nAbstract: Numerous liver diseases are characterized by late diagnosis, rapid progression and high incidence, seriously threatening public health. Though widely used, traditional treatments such as drug therapy, resection and transplantation have substantial limitations. Therefore, developing novel preventive strategies and specialized therapies is crucial. As Chinese medicine continues to modernize, increasing evidence suggests that certain Chinese medicine ingredients can protect the liver. Astragaloside IV (AS‑IV) is a natural saponin extracted from the root of the traditional herb Astragalus membranaceous. It exhibits diverse pharmacological activities, including anti‑inflammatory, antioxidant, antiapoptotic and anticancer properties, and is recognized for treating neurological, cardiovascular and metabolic disorders, and cancer. These discoveries indicate its substantial promise for the treatment of liver diseases. Therapeutic trials revealed its hepatoprotective effects for the treatment of various liver diseases, such as non‑alcoholic fatty liver disease, liver fibrosis, hepatocellular carcinoma and liver injury induced by heavy metals, drugs, or alcohol and involve various signaling pathways such as nuclear factor erythroid 2‑related factor 2, toll‑like receptor 4, acetyl‑CoA carboxylase, protein kinase B, nuclear factor κB and adenosine monophosphate‑activated protein kinase. The present study presents a narrative review that comprehensively summarizes existing evidence regarding the therapeutic influence of AS‑IV on diverse liver disorders and deeply analyzes the molecular mechanisms underlying its action in liver disease. The objective is to comprehensively offer insights and references for relevant scientific research and clinical drug development to improve nutritional supplements for liver health.","42429144":"ID: 42429144\nTitle: Gut dysbiosis‑derived butyrate loss predicts feeding intolerance: Multiomics evidence guiding nurse‑driven microbiota‑supportive interventions (Review).\nAbstract: Feeding intolerance (FI) is a common and debilitating challenge among critically ill patients that is linked to a pathway involving the collapse of the gut microbial ecology. The present review synthesizes multiomics evidence supporting a framework whereby critical illness‑associated gut dysbiosis results in a functional deficit of a microbially derived short‑chain fatty acid butyrate, a pivotal metabolite involved in maintaining intestinal barrier integrity, immuneoregulation and gastrointestinal motility. The loss of butyrate‑producing bacteria and their genetic pathways is strongly correlated with FI and may represent a contributory pathogenic mechanism. Key butyrate‑producing organisms diminished during this process include Faecalibacterium prausnitzii and Roseburia spp. Building upon this mechanistic framework, a pragmatic, nurse‑driven intervention model aimed at preserving and restoring microbial health in critically ill patients was proposed. This model is founded on four principal strategies: Minimizing iatrogenic harm (such as antibiotic/proton pump inhibitor stewardship), targeted microbiota nourishment (pre/synbiotics), cautious microbial restoration (probiotics/fecal microbiota transplantation) and innovative monitoring approaches. By integrating principles of microbial ecology with clinical nursing science, the present review provides a framework for developing nurse‑driven protocols designed to address the underlying pathophysiology of FI and improve patient outcomes.","42429253":"ID: 42429253\nTitle: Association between Dietary Intake of Live Microbes and Asthma Risk in Children and Adolescents Aged 6-15 Years: A Cross-sectional analysis.\nAbstract: Emerging evidence implicates gut dysbiosis in asthma pathogenesis via the gut-lung axis. This cross-sectional study aimed to examine the associations between dietary live microbes intake and asthma risk among US children and adolescents aged 6 to 15 years. We analyzed data from the 2007-2018 National Health and Nutrition Examination Survey. Dietary live microbes intake was evaluated using the Sanders method and categorized into low, medium, and high categories. Asthma status was determined by self-report. Multivariable binary logistic regression was used to evaluate the association between dietary live microbe intake and asthma prevalence. Of the 7,547 participants (mean age 10.8 years; 51.9% male) included, the overall prevalence of asthma was 11.3%. Compared with the low dietary live microbes intake group, the multivariate-adjusted odds ratio (95% confidence intervals) for asthma in the medium and high intake groups were 0.75 (0.63-0.88) and 0.52 (0.41-0.64), respectively (P for trend < 0.001). Subgroup analyses suggested trends toward stronger protective associations among girls (P for interaction = 0.073) and those exposed to household smoking (P for interaction = 0.070). Sensitivity analyses using propensity score matching and additional adjustment for prebiotics, probiotics, and synbiotics yielded results consistent with the primary analysis. Higher dietary live microbe intake was significantly associated with lower asthma prevalence in US children and adolescents aged 6-15 years. These findings support additional investigation of dietary live microbe consumption as a modifiable factor for asthma prevention in this age group.","42429613":"ID: 42429613\nTitle: Gut Microbiota, Immunity, and Metabolism in the Progression From Chronic Liver Disease to Hepatocellular Carcinoma.\nAbstract: The progression from chronic liver injury to hepatocellular carcinoma (HCC) should be viewed as a heterogeneous continuum of immune, metabolic, fibrotic, and microbial remodeling rather than as a single linear route. Although this review uses the MASLD-MASH-fibrosis/cirrhosis-HCC sequence as a mechanistically informative model, the gut-liver-immune framework is also relevant, with important etiology-specific differences, to alcohol-associated liver disease (ALD), chronic hepatitis B virus (HBV) infection, chronic hepatitis C virus (HCV) infection, and mixed-etiology liver disease. Across these contexts, hepatocyte lipotoxicity or viral/alcohol-induced injury, mitochondrial stress, endotoxemia, altered bile-acid signaling, fibrotic remodeling, and immune exhaustion progressively reshape the hepatic microenvironment toward tumor-permissive inflammation and immune escape. We integrate transcriptomic, single-cell, spatial, microbial, and metabolomic evidence to define stage- and etiology-dependent immunometabolic states. Particular emphasis is placed on microbial metabolites, including short-chain fatty acids, secondary bile acids, and tryptophan-derived indoles, which engage host receptors such as FFAR2/3, GPR109A, FXR, TGR5, AhR, and PXR to influence lipid metabolism, epithelial barrier integrity, cytokine programs, epigenetic remodeling, and antitumor surveillance. We further discuss how sex, baseline microbiome composition, hepatic zonation, and preclinical model selection influence disease trajectories and therapeutic responses. By focusing on the gut microbiota-metabolism-immunity axis, this review provides a systems-level framework for biomarker discovery, risk stratification, precision nutrition, and rational combination therapies. Targeting the coordinated interplay among diet, microbiota, metabolism, immunity, and the hepatic spatial niche may help intercept chronic liver disease before malignant transformation and improve therapeutic responses in established HCC.","42429614":"ID: 42429614\nTitle: Higher abundance of Faecalibacterium prausnitzii in the gut microbiome is associated with a lower risk of sepsis development among 6,372 individuals followed for 20 years.\nAbstract: The human gut microbiome has been suggested to be linked with the risk of developing sepsis, a life-threatening medical emergency. However, it remains unclear whether the gut microbiome is an independent predictor of long-term sepsis risk in the general adult population. Here, we investigated for the first time the prospective association between the gut microbiome and incident sepsis in the general population. The study sample (FINRISK) consisted of 6,372 individuals who underwent fecal sampling in 2002 and were followed for incident sepsis. We used multivariable-adjusted models to study the associations of microbial alpha-diversity, beta-diversity, taxa, butyrate producers, and predicted pathways with incident sepsis. Two hundred and forty participants developed sepsis over a follow-up of 19.8 years. A 1-SD increase in Faecalibacterium prausnitzii_C_71351 abundance was associated with 21% (95% CI, 10%-30%; FDR = 0.03) lower risk of sepsis. Higher abundances of six other species were associated with higher sepsis risk (FDR < 0.05 for all). Five of these species were positively associated with C-reactive protein. The species-sepsis associations were consistent across various subgroups. Moreover, in an independent validation cohort of 4,248 individuals, we found a similar association between Faecalibacterium and a lower risk of future sepsis. Additionally, overall pathways related to carbohydrate degradation, energy production, and sulfur metabolism were positively linked to incident sepsis. We did not detect any associations of alpha-diversity, beta-diversity, or butyrate producers with incident sepsis. Future studies should investigate the causality of these associations and the mechanisms by which the identified species may influence sepsis development.IMPORTANCEPrevious cross-sectional and case-control studies have linked changes in the gut microbiome with the occurrence of sepsis. However, the relationship between the gut microbiome and the risk of incident sepsis in the general adult population remains unexplored. Here, we found clear evidence on the association of gut microbiome species with incident sepsis in a large population cohort. In particular, we provided an in-depth analysis of the negative link between F. prausnitzii and sepsis risk, which was robust across independent cohorts. This finding supports a potential protective role of F. prausnitzii, but further experimental investigation is required. We also show that six species, including Clostridium symbiosum-a causative agent of bacteremia/sepsis in few cases-are positively linked to incident sepsis. Most of these species were also positively linked to an inflammatory marker. Our research provides the groundwork for future experimental analysis of the detected associations to understand their role in infection.","42429658":"ID: 42429658\nTitle: Effects of gut microbiota on the susceptibility of ischemic stroke in mice.\nAbstract: Ischemic stroke is a highly prevalent disease with limited therapeutic options, and emerging evidence suggests that the gut microbiota influences stroke pathophysiology. However, whether the gut microbiota affects individual susceptibility to ischemic stroke remains unclear. Here, middle cerebral artery occlusion was performed to stratify mice into ischemic stroke-sensitive (SEN: reaching humane endpoints within day 1) and ischemic stroke-resistant (RES: surviving to day 7) groups based on post-stroke survival. SEN mice exhibited more severe brain injury than RES mice, accompanied by increased systemic inflammation and elevated intestinal permeability. Fecal microbiota from SEN or RES donors was transplanted into antibiotic-treated recipients. Mice receiving SEN microbiota developed significantly worse outcomes compared with those receiving RES microbiota. Multi-omic analyses of cecal contents, including 16S rRNA gene sequencing and liquid chromatography-mass spectrometry/mass spectrometry-based untargeted metabolomics, identified reduced butyrate-producing bacteria and altered glutathione metabolism as potential contributors to stroke susceptibility. Collectively, these findings demonstrate that gut microbiota and microbial metabolites modulate susceptibility to ischemic stroke. The role of the gut microbiota in determining susceptibility to ischemic stroke has remained poorly defined. This study demonstrates that microbiota dysbiosis and metabolite alterations functionally increase vulnerability to stroke injury, highlighting the gut microbiome as a potential target for risk stratification and preventive interventions. Modulating the gut microbiota may therefore represent a novel strategy for reducing stroke susceptibility.","42429666":"ID: 42429666\nTitle: Sialidase inhibitor modulates gut microbiota and enhances mucosal protection in the treatment of ulcerative colitis.\nAbstract: Ulcerative colitis (UC) is characterized by mucosal barrier erosion, a process exacerbated by bacterial sialidases. We investigated the therapeutic efficacy of the sialidase inhibitor (SI) in UC. In a pilot randomized clinical trial, SI intervention significantly improved clinical symptoms and endoscopic outcomes in mild-to-moderate UC patients. This improvement correlated with an enrichment of butyrate-producing taxa and beneficial metabolic pathways. In a dextran sulfate sodium-induced colitis mouse model, SI attenuated inflammation and restored mucus layer integrity, accompanied by increased expression of Muc2 and Tff3. Crucially, unlike broad-spectrum antibiotics, SI preserved microbial community resilience while specifically enriching beneficial mucolytic commensals, Akkermansia muciniphila and Bacteroides acidifaciens. These findings identify SI as a promising therapeutic strategy that targets sialidase activity to reinforce the mucosal barrier and restore gut homeostasis.IMPORTANCEThe gut microbiota plays a pivotal role in maintaining mucosal integrity and intestinal homeostasis; however, dysbiosis-driven mucus layer degradation remains a hallmark of ulcerative colitis (UC). Current interventions like antibiotics often disrupt microbial diversity, exacerbating dysbiosis and failing to address mucosal thinning, which is a critical factor in UC progression. Developing strategies to reinforce the mucus barrier without compromising microbial balance is urgently needed, but such approaches remain underexplored. Our study demonstrates that sialidase inhibitors (SIs) uniquely preserve mucosal thickness by curbing microbial mucin degradation while selectively enriching beneficial taxa and butyrate-producing bacteria. Unlike antibiotics, SIs enhance mucosal protection without destabilizing microbial communities, offering a dual-action therapeutic strategy. This work bridges a critical knowledge gap, providing evidence for microbiota-targeted therapies that synergistically restore mucosal health and microbial ecology in UC.CLINICAL TRIALSThis study was registered with the Chinese Clinial Trial Registry as ChiCTR2000028767.","42430016":"ID: 42430016\nTitle: Therapeutic Delivery of Bone Marrow Mesenchymal Stem Cell-Derived Exosomal miR-143-3p Inhibits Myocardial and Systemic Inflammation and Attenuates Sepsis-Related Myocardial Injury.\nAbstract: Sepsis-related myocardial injury (SRMI) is a major contributor to mortality in septic patients, driven by uncontrolled inflammation and macrophage dysregulation. Bone marrow mesenchymal stem cell-derived exosomes (BMSC-Exos) possess immunomodulatory properties, but their cardioprotective mechanisms remain unclear. Here, we investigated whether BMSC-Exos deliver microRNA-143-3p (miR-143-3p) to reprogram macrophages and attenuate SRMI. Exosomes were isolated from murine bone marrow mesenchymal stem cells and characterized by electron microscopy, nanoparticle tracking analysis, and immunoblotting. In lipopolysaccharide-stimulated macrophages, BMSC-Exos promoted a shift from pro-inflammatory M1 to reparative M2 polarization, and reduced pro-inflammatory cytokine secretion. In a mouse model of endotoxemia, BMSC-Exo administration improved seven-day survival, preserved cardiac function, decreased circulating myocardial injury markers, and increased the proportion of cardiac M2 macrophages. MicroRNA sequencing identified miR-143-3p as highly enriched in BMSC-Exos but downregulated in circulating exosomes from septic mice. Delivery of miR-143-3p mimics recapitulated the protective effects of BMSC-Exos, while inhibition of miR-143-3p exacerbated injury. Mechanistically, miR-143-3p directly targeted Toll-like receptor 4 (TLR4) and suppressed the downstream myeloid differentiation primary response 88/nuclear factor-κB (MyD88/NF-κB) signaling pathway. Furthermore, TLR4 knockdown phenocopied the anti-inflammatory and M2-polarizing effects of miR-143-3p. These findings indicate that BMSC-Exos attenuate SRMI by transferring miR-143-3p to macrophages, where it inhibits TLR4/MyD88/NF-κB signaling and promotes M2 polarization, highlighting a potential therapeutic strategy for septic cardiac injury.","42430127":"ID: 42430127\nTitle: Oral Lysozyme Attenuates Neuroinflammation and Brain Injury After Traumatic Brain Injury Through Gut Microbiota-Dependent Reprogramming of Tryptophan Metabolism.\nAbstract: Traumatic brain injury (TBI) induces secondary neuroinflammation and gut dysbiosis. This study investigated whether oral lysozyme confers neuroprotection after TBI through gut microbiota-dependent metabolic reprogramming of tryptophan metabolism. In a severe TBI mouse model, neurological function, neuroinflammation, intestinal barrier integrity, and systemic immune homeostasis were assessed following oral lysozyme administration. Fecal untargeted metabolomics, antibiotic-mediated microbiota depletion, and fecal microbiota transplantation (FMT) were used to explore microbiota involvement. Cerebrospinal fluid (CSF) from 10 matched pairs of patients with severe TBI was analyzed for tryptophan pathway metabolites by liquid chromatography-mass spectrometry. Lysozyme improved neurological outcomes, attenuated neuronal apoptosis and neuroinflammation, and restored peripheral CD4+/CD8+ T cell homeostasis. Metabolomics revealed enrichment of fecal tryptophan metabolites (indole-3-carboxaldehyde, indolelactic acid, kynurenic acid [KYNA]) and a shift in cerebral kynurenine metabolism toward the KYNA branch. These associations were abolished by microbiota depletion and reproduced by FMT. Favorable clinical outcomes were associated with higher CSF KYNA and an elevated KYNA/QA ratio. Oral lysozyme was associated with attenuated TBI-induced neuroinflammation and brain injury, potentially through gut microbiota-dependent tryptophan metabolism reprogramming. Concordance between preclinical and clinical metabolomic data supports lysozyme as a candidate microbiota-targeted therapeutic strategy. The KYNA/QA ratio warrants further validation as a prognostic indicator in larger, longitudinal cohorts.","42430365":"ID: 42430365\nTitle: Gut Microbiota Drives Aging-related Erythropoiesis Impairment via Phenylacetic Acid-induced Histone Phenylacetylation.\nAbstract: Anemia, the most prevalent hematologic disorder in older adults, imposes a significant burden of cardiovascular events, cognitive decline, and mortality. However, the mechanisms underlying aging-related anemia, especially epigenetic dysregulation in hematopoietic stem and progenitor cells (HSPCs), remain incompletely understood. Although the gut microbiota is critical for hematopoiesis, its specific contribution to aging-related erythropoiesis impairment remains unclear. Here, we reveal that aging markedly activates phenylalanine metabolism and elevates plasma phenylacetic acid (PAA) levels in both humans and mice. We identify Odoribacter splanchnicus (O.splanchnicus) as a key gut symbiont whose abundance is significantly increased in aged mice and which directly drives PAA production from phenylalanine via the oxoacid:ferredoxin oxidoreductase (OFOR) superfamily encoded by porA,nifJ, and iorA/iorB. Rifaximin treatment selectively reduces O.splanchnicus and plasma PAA, thereby alleviating aging-related anemia. Mechanistically, PAA promotes a novel post-translational modification (PTMs) termed histone lysine phenylacetylation (Kpa) through the acetyltransferases HBO1. Elevated histone Kpa increases chromatin accessibility at the GATA2 promoter, disrupts the GATA switch, and blocks erythroid differentiation of HSPCs. In vivo, supplementation with sodium phenylacetate (NaPA) exacerbates anemia in microbiota-depleted mice, whereas the HBO1 inhibitor WM-3835 restores erythropoiesis by reversing histone Kpa and normalizing the GATA switch. Furthermore, dietary phenylalanine restriction lowers circulating PAA and effectively ameliorates aging-related anemia in both naturally aged mice and O.splanchnicus-colonized mice. These findings provide the first evidence that gut microbiota-derived PAA plays a critical role in the development of aging-related erythropoiesis impairment and offer multiple translatable strategies for treating this condition.","42430494":"ID: 42430494\nTitle: p38 MAP kinase senses short-chain fatty acids to attenuate Toll-like receptor signaling and intestinal inflammation.\nAbstract: Toll-like receptor (TLR) signaling is critical for innate immune system. However, whether it is directly modulated by microbiota-derived metabolites remains unclear. Here, we show that the short-chain fatty acids (SCFAs) propionate and butyrate suppress TLR signaling by directly binding p38α MAP kinase, promoting its interaction with TAB1, thereby activating p38α via autophosphorylation. Activated p38α then phosphorylates TRAF3 at serine 85, inhibiting K63-linked polyubiquitylation of TRAF3 and disrupting TBK1-IRF3 activation, leading to reduced macrophage activation and intestinal inflammation. In ulcerative colitis patients, fecal levels of propionate and butyrate positively correlate with p38α activity and TRAF3 S85 phosphorylation, but inversely correlate with TBK1 activation, and cytokine levels. Notably, oral administration of propionate in three patients with ulcerative colitis markedly improved intestinal inflammation and clinical symptoms. These findings reveal p38α as a direct sensor for microbiota-derived SCFAs that suppress TLR signaling through nonmetabolic functions of propionate and butyrate, providing the first clinical evidence that propionate supplementation represents a practical dietary strategy for ulcerative colitis management.","42431043":"ID: 42431043\nTitle: Microstructure-driven oxidative stability and gut microbiota modulation of flaxseed oil Nano-capsules: A freeze-drying versus vacuum-drying comparative study.\nAbstract: This study compared freeze-drying (FD) and vacuum-drying (VD) for preparing flaxseed oil nano-capsules (FO NC). Structurally, FD formed a porous matrix, while VD caused flattening and aggregation. Although both methods achieved effective encapsulation, FD-FO NC better preserved heat-sensitive components, exhibited lower moisture content (1.39%) and hygroscopicity (1.89%). During 28-day storage, FD-FO NC showed superior stability: controlled reduction in psize (669.03 to 322.28 nm), higher retention of encapsulation efficiency (90.44% to 65.61% in 3 weeks), and lower peroxide values (<0.7 g/100 g). In vitro fermentation indicated FD-FO NC more effectively modulated gut microbiota, enriching beneficial bacteria and increasing SCFAs production (acetate: 20.07 mmol/L; butyrate: 1.90 mmol/L). The novelty of this work lies in its systematic comparative evaluation of FD and VD for nano-capsules, linking their microstructure and oxidative stability to in vitro gut microbiota modulation and SCFAs production, thereby providing new insights for the design of functionally enhanced delivery systems.","42431475":"ID: 42431475\nTitle: Harnessing the Microbiome for Head and Neck Cancer Therapy: From Mechanistic Insights to Translational Opportunities.\nAbstract: The human microbiome, particularly the diverse microbial communities in the oral cavity and gut, plays a critical role in the pathogenesis, progression, and treatment response of head and neck squamous cell carcinoma (HNSCC). Emerging evidence indicates that specific microbial communities can bidirectionally modulate cancer therapeutic modalities. Moreover, interventions such as probiotics, prebiotics, and fecal microbiome transplantation have the potential to improve treatment efficacy and alleviate adverse effects. This review outlines the mechanisms underlying oral and gut microbiota in HNSCC development and progression, focusing on their bidirectional regulation of efficacy and toxicity across standard treatments, including surgery, radiotherapy, chemotherapy, targeted therapy, and immunotherapy. We emphasize that microbial signatures not only serve as predictive biomarkers and therapeutic targets but also constitute a fundamental component of personalized oncology in HNSCC, providing a comprehensive framework for integrating microbiota-based strategies into clinical practice.","42431620":"ID: 42431620\nTitle: Prebiotics and asthma: current insights and future directions from a bibliometric analysis.\nAbstract: Prebiotics have gained attention as a microbiome-modulating strategy in asthma because they may influence immune regulation through the gut-lung axis. However, evidence on prebiotics and asthma remains distributed across allergy, immunology, nutrition, microbiology, and respiratory medicine. This study aimed to map global research trends, influential contributors, and thematic development in prebiotics-asthma research using bibliometric analysis. This bibliometric study analyzed English-language articles and reviews indexed in Scopus. Prebiotic-related and synbiotic-related terms were combined using OR and then linked with asthma-related terms using AND. Eligible records were screened for relevance to prebiotics and asthma. Bibliometric analyses and visualizations were performed using Biblioshiny and VOSviewer to evaluate publication output, leading contributors, citation impact, keyword co-occurrence, and temporal research trends. A total of 296 publications from 166 sources were included. The earliest eligible publication was published in 2002. Annual scientific production increased over time, with an annual growth rate of 13.66% and the highest output in 2024. Review articles outnumbered original articles. The United States was the leading contributor, followed by Australia, the Netherlands, Italy, and China. Keyword analysis identified three major domains: mechanistic and immunologic studies, early-life allergy prevention, and microbiota-focused modulation. Trend analysis showed a shift toward gut microbiome, short-chain fatty acids, immune dysregulation, and gut-lung axis. Prebiotics-asthma research is a relatively recent but steadily growing field with increasing emphasis on microbiome-mediated and mechanistic pathways. However, asthma-specific translational evidence remains limited, supporting the need for standardized clinical studies and integrative multi-omic approaches.

A man in his 60s presented with light-headedness, vomiting and abdominal pain. He developed acute aphasia and right-sided weakness within 24 hours, and although serial CT brain imaging and CT angiography were normal, conscious level deteriorated rapidly, such that he required intubation and mechanical ventilation. MRI brain demonstrated symmetrical basal ganglia T1 hyperintensity. Metabolic investigation identified hyperammonaemia (147 µmol/L). He was treated with lactulose, rifaximin and continuous veno-venous haemofiltration with biochemical and neurological improvement and resolution of neurological deficits. In the absence of overt liver failure, small bowel bacterial overgrowth was considered the most likely cause although potential additional contributory factors were also identified. This case highlights the need to measure ammonia early in otherwise unexplained encephalopathy, even when liver function tests are normal.","42431962":"ID: 42431962\nTitle: Intestinal FXR deficiency uncouples steatosis protection from liver inflammation and fibrosis in MASH-diet fed mice.\nAbstract: The Farnesoid X Receptor (FXR), a nuclear bile acid (BA) receptor highly expressed in the liver and intestine, is a potential pharmacological target for Metabolic dysfunction-Associated SteatoHepatitis (MASH). While intestinal FXR inhibition reduces high-fat diet (HFD)-induced hepatic steatosis, its role in MASH progression remains unclear. This study investigates the impact of intestinal FXR-deficiency on MASH development in a diet-induced murine model. Intestinal FXR-deficient (intFXR KO) and control mice were fed a high-fat, sucrose, and cholesterol-enriched diet (HFSC) for 24 weeks. Intestinal immune phenotyping, microarray, 16 S rRNA sequencing, bile acid quantification and liver assessments (histology, biochemistry and single-cell RNA sequencing (scRNA-seq)) were performed. intFXR KO mice were protected against HFSC diet-induced obesity and hepatic steatosis but exhibited altered expression of intestinal barrier-associated genes, with increased cytotoxic CD8+ T-lymphocytes. Microbiota composition and bile acid profiles were altered, including reduced Lachnospiraceae species correlating negatively with liver hyocholic acid levels. Despite a protection against hepatic steatosis, liver inflammation and fibrosis were unchanged in intFXR KO mice. Transcriptomic and Immune cell scRNA-seq analysis revealed alteration in immune-related pathways with an increased neutrophil proportion and higher cDC1:cDC2 and CD4:CD8 T cell ratios. Thus, intestinal FXR-deficiency limits steatosis but promote a distinct hepatic immune-inflammatory response and does not prevent progression to MASH.","42431994":"ID: 42431994\nTitle: Dietary proanthocyanidins ameliorate age-related cognitive decline and neuroinflammation in thyroxine-induced accelerated aging-like mice via the gut microbiota-SCFAs-5-HTP axis.\nAbstract: Age-related cognitive impairment is a major public health concern associated with neuroinflammation and gut microbiota dysbiosis. Proanthocyanidins (PC), a class of dietary polyphenols, have been suggested to modulate the gut-brain axis. Here, we investigated the mechanisms by which PC alleviate cognitive deficits in a thyroxine-induced accelerated aging-like mouse model. PC supplementation significantly improved spatial learning and memory, as assessed by the Morris water maze. These effects were accompanied by modulation of gut microbiota composition and altered fecal short-chain fatty acids (SCFAs), particularly butyrate and propionate. PC also improved intestinal barrier function, increased colonic tryptophan hydroxylase 1 (TPH1) expression, and regulated 5-hydroxytryptophan (5-HTP)/serotonin (5-HT)-related pathways. In parallel, hippocampal neuroinflammatory responses were attenuated. Collectively, these findings suggest that the neuroprotective effects of PC are associated with a gut microbiota-SCFAs-5-HTP/5-HT axis. This study highlights the potential of dietary proanthocyanidins as a nutritional strategy for mitigating cognitive impairment under thyroxine-induced accelerated aging-like conditions.","42432504":"ID: 42432504\nTitle: Impact of fecal microbiota transplantation on lipid parameters in patients with metabolic syndrome: a meta-analysis.\nAbstract: Metabolic syndrome (MetS) is a global health challenge, with impaired lipid metabolism as a key feature.

This meta-analysis systematically assessed the influence of allogenic FMT on lipid parameters in patients with MetS, unraveling its potential as an innovative therapeutic modality for this population. A meta-analysis was performed to explore the impact of allogenic FMT on lipid parameters (triglycerides, total cholesterol [TCHO], high-density lipoprotein cholesterol [HDL-C] and low-density lipoprotein cholesterol [LDL-C]) in patients with MetS. Terms regarding FMT and MetS were searched in PubMed/Medline, EMBASE, Web of Science, the Cochrane Library, and Scopus from the inception of the databases until 31 August 2023. Nine randomized controlled trials (RCTs) were included and subgroup analyses according to follow-up durations were performed. This study was registered in PROSPERO (ID CRD42023389890). A total of 248 patients were included. Patients undergoing allogenic FMT manifested significantly lower TG level compared with control group (receiving placebo or autologous FMT, pooled MD -0.15 [95% CI: -0.29, -0.01]), as well as higher HDL-C level (MD 0.07 [95% CI: 0.02, 0.12]). Subgroup analysis confirmed that these effects were significant at 4 to 6 weeks post-FMT (TG: MD -0.16, 95% CI: -0.32, -0.01; HDL-C: MD 0.08, 95% CI: 0.02, 0.15). No significant difference was observed between allogenic FMT and control group concerning TCHO and LDL-C levels regardless of lengths of follow-up. In subgroup analysis, the results regarding TG and HDL-C remained consistent in the subgroup with 4 to 6 weeks of follow-up. An overall reduction in TG level and elevation in HDL-C level was observed in patients with MetS receiving allogenic FMT. A potential optimal timeframe for FMT efficacy manifestation might be 4 to 6 weeks after first administration.

This secondary analysis of a randomized controlled trial aimed to elucidate these differential effects and explore the specific mediating roles of SCFA changes. While maintaining their habitual non-staple food intake, 102 participants were randomly assigned to either the WG or RG groups and provided with standardized ingredients for staple food preparation. Fecal SCFAs, blood pressure, blood glucose, renal function markers, body composition, and systemic immune-inflammation markers were assessed at baseline and post-intervention, with further exploration of inter-variable correlations and mediation pathways among these factors. WG favored butyrate percentage, while RG increased acetate proportion. WG consumption improved post-prandial diastolic blood pressure (DBP), an effect not observed in the RG group, and yielded a significantly greater reduction in serum creatinine. Conversely, RG intake resulted in statistically significant short-term body composition changes, reducing fat mass and increasing lean mass. Mediation analysis revealed that changes in butyrate and acetate acted as suppressors in the pathways linking dietary grain type to post-prandial DBP and blood urea nitrogen changes, respectively. Systemic immune-inflammation markers did not differ between groups. In our study, we observed that WG and RG consumption elicited distinct SCFA profiles and divergent metabolic and body composition responses in middle-aged and older adults. WG intake preferentially benefited blood pressure and renal function, potentially through SCFA-related pathways, while RG intake unexpectedly improved short-term body composition. These findings highlight the complexity of grain-microbiota-host interactions and suggest that the grain consumed substantially influences metabolic outcomes through SCFA-mediated mechanisms.

The objectives of this study were to characterize the structural, functional, and molecular changes in rumen epithelium during ARA and to determine which rumen fluid components drive these changes. Twelve sheep were used in this study, of which six were fasted overnight followed by ad libitum access to a concentrate diet to develop ARA, and six sheep were fed alfalfa hay to serve as controls. Forty-eight hours later, all sheep were euthanized, and rumen tissue samples were collected for histological analysis, ex vivo permeability assessment, and RNA sequencing. Primary rumen epithelial cells were isolated from additional healthy sheep for in vitro experiments. Statistical analyses were performed using Student's t-test or one-way ANOVA followed by Tukey's HSD test. The rumen epithelium from acidotic sheep showed increased permeability and histological damage, including parakeratosis, epithelial lifting, and partial loss of the stratum corneum layer of the rumen epithelium, compared to that from control sheep (P < 0.05). RNA sequencing identified 2,563 differentially expressed genes (adjusted P < 0.05 and |log2 fold change| ≥ 1) in the rumen epithelium between acidotic and control sheep. Functional enrichment analyses revealed that genes upregulated in acidotic rumen were enriched in ribosome biogenesis, translation, and keratinization, whereas genes downregulated in acidotic rumen were associated with immune response, cell adhesion, and tight junction (P < 0.05). Examples of differentially expressed genes were CLDN1, OCLN, and TJP1 (tight-junction genes); MRPL23, NOP53, and RPS6 (ribosome and translation genes); and IL17B, TLR4, and MYD88 (immune genes). To determine which rumen fluid changes in acidotic versus control sheep are directly responsible for differential expression of these genes in the rumen, primary ovine rumen epithelial cells were treated with pH, lipopolysaccharides, L-lactic acid, D-lactic acid, and butyrate at levels approximating those in acidotic or control sheep. Low medium pH (5.0) decreased OCLN and MYD88 expression while increasing TJP1, MRPL23, and TLR4 expression compared to normal medium pH (7.4) (P < 0.05). LPS, L-lactate, and D-lactate at concentrations found in rumen fluid of acidotic sheep did not affect the expression of these genes compared to those found in control sheep (P < 0.05). Butyrate at concentration found in rumen fluid of control sheep increased (P < 0.05) CLDN1, OCLN, and RPS6 expression while having no effect on the other genes, compared with concentration found in rumen fluid of acidotic sheep. In conclusion, ARA is associated with marked structural, functional, and transcriptomic changes in rumen epithelium, and these changes may be partially driven by reduced rumen pH and reduced butyrate concentration in rumen fluid. Acute ruminal acidosis is a digestive disorder that affects agriculturally important ruminants such as cattle and sheep. During acute ruminal acidosis, the rumen pH decreases sharply, and potentially harmful compounds such as lipopolysaccharide and D-lactic acid build up in the rumen. In this study, we determined the changes that occur in the rumen tissue during acute ruminal acidosis and identified the rumen fluid components responsible for these changes. We found that the rumen epithelium of sheep with acute ruminal acidosis was leaky and that its surface was damaged. We also found significant gene expression differences in the rumen tissue between acidotic and normal sheep. These gene expression differences suggest barrier dysfunction and immune suppression in the rumen of acidotic sheep. Data of in vitro experiments using primary sheep rumen epithelial cells suggest that significantly lowered pH and significantly reduced butyrate production impair rumen epithelial integrity, barrier function, and local immune response, which may in turn contribute to systemic problems such as systemic inflammation in affected animals.","42433126":"ID: 42433126\nTitle: A Modular Liver-Microbial Microfluidic Platform to Evaluate Therapeutic and Adverse Effects of Microbial Metabolites.\nAbstract: Gut microbial metabolites, particularly short-chain fatty acids (SCFAs) like butyrate, play a significant role in modulating non-alcoholic fatty liver disease (NAFLD). While animal studies show that butyrate-producing microbes can improve liver function, full recovery is hindered by unintended side effects from commensal bacteria. These underlying biomolecular mechanisms remain elusive, due to the lack of in vitro coculture models capable of systematically examine both the therapeutic benefits of engineered microbial metabolites and their potential adverse impacts. To address this, we developed a modular microfluidic platform to study the effects of live microbial metabolites on hepatic steatosis and liver function. We created a microfluidic-based hepatic steatosis model integrated with a compartmentalized microbial module, facilitating the study of how metabolites produced by live microbes affected the liver model. We compared the effects of synthetic SCFA supplementation with those of coculturing with a control and butyrate-producing E. coli Nissle 1917 (EcN) strains on hepatic steatosis. Our findings showed that live microbial coculture did not phenocopy exogenous SCFA treatment. While both treatments reduced steatotic lipid accumulation, live microbes induced inflammatory and hepatic metabolic changes, suggesting contributions from additional microbial factors, emphasizing the need to thoroughly assess side effects in liver disease treatment.","42433272":"ID: 42433272\nTitle: The role of the microbiota in hematological malignancies: A narrative review of mechanisms and therapeutic potential.\nAbstract: The human microbiota, particularly the gut microbiome, plays a central role in maintaining immune homeostasis, regulating hematopoiesis, and modulating host metabolism through bioactive metabolites such as short-chain fatty acids (SCFAs), bile acids, and tryptophan-derived compounds. Disruption of this microbial ecosystem (dysbiosis) has emerged as a key contributor to the development and progression of hematological malignancies (HMs), including acute and chronic leukemias, lymphomas, and multiple myeloma. This narrative review synthesizes recent evidence (2022-2025) on the complex bidirectional interactions between the microbiota and HMs, highlighting their biological and clinical significance. Current evidence indicates that the microbiota influences hematological malignancies through multiple interconnected mechanisms, including immune regulation, inflammatory signaling, maintenance of hematopoietic homeostasis, and microbial metabolite-mediated modulation of the tumor microenvironment. Dysbiosis has been associated with disease progression, increased susceptibility to infections, impaired treatment tolerance, and inferior clinical outcomes. Conversely, chemotherapy, broad-spectrum antibiotics, and hematopoietic stem cell transplantation profoundly reshape microbial communities, further exacerbating dysbiosis and contributing to complications such as graft-versus-host disease following allogeneic transplantation. Emerging microbiota-targeted interventions, including dietary modulation, probiotics, prebiotics, and fecal microbiota transplantation, show promise for restoring microbial homeostasis and improving therapeutic outcomes. Furthermore, microbiome-derived biomarkers are increasingly being investigated for predicting treatment response, relapse risk, and immunotherapy efficacy. Despite these advances, important challenges remain, particularly in establishing causal relationships, standardizing microbiome profiling, and validating clinical applications through well-designed prospective and randomized studies. Overall, the accumulating evidence supports the microbiota as a critical determinant of hematological cancer biology and treatment response. Integrating microbiome-based diagnostics and therapeutic strategies into precision hematology may offer new opportunities to improve patient management and long-term clinical outcomes.","42433375":"ID: 42433375\nTitle: Shared inflammatory architecture and therapeutic tensions between psoriasis and Crohn's disease.\nAbstract: Psoriasis and Crohn's disease are chronic immune-mediated inflammatory diseases affecting distinct barrier organs, yet epidemiological, genetic, transcriptomic, and therapeutic evidence supports partial immune convergence between them. This review argues that the relationship between psoriasis and Crohn's disease reflects partial immune convergence shaped by tissue context, rather than a single shared disease entity. TNF-α and IL-23-centered type 17 immunity represent the most clinically relevant shared upstream programs, whereas downstream effector pathways, especially IL-17-related responses, are shaped differently by skin and gut barrier architecture, resident immune ecology, microbial exposure, and repair demands. We discuss the gut-skin axis with caution: barrier dysfunction, dysbiosis, microbial metabolites, and immune-cell trafficking may connect skin and intestinal inflammation, but direct causal evidence in humans remains limited. TNF inhibitors, IL-12/23 blockade, and selective IL-23 inhibitors are the most plausible options for selected patients requiring treatment compatible with both skin and gut disease, whereas IL-17 blockade and paradoxical psoriasiform reactions illustrate organ-specific therapeutic tensions. Future progress will depend on patient stratification using clinical phenotypes, biomarkers, tissue profiling, and treatment history to identify patients in whom skin and intestinal inflammation are driven by overlapping immune mechanisms.","42434047":"ID: 42434047\nTitle: The Plastic Within: Micro- and Nanoplastics in Human Tissues and the Nutritional Context for Exposure Mitigation.\nAbstract: Microplastics (MPs) and nanoplastics (NPs) are increasingly detected in human tissues, prompting concern about potential biological effects. Yet, for most outcomes, the literature remains dominated by detection studies and preclinical toxicology, with limited human dose-response data. We conducted a narrative review of peer-reviewed literature (2000-2025), prioritizing human biomonitoring and tissue-detection studies, observational health-outcome studies, and mechanistic evidence that plausibly links exposure to cardiometabolic, reproductive, and neuroinflammatory pathways. Certainty of evidence was appraised using GRADE principles where applicable and explicitly separated from mechanistic plausibility. MPs/NPs have been reported in blood, lung, placenta, atherosclerotic plaques, brain, liver, and testicular tissue. The most clinically salient human outcome signal to date is an association between plaque microplastics and subsequent major adverse cardiovascular events in an observational cohort (hazard ratio 4.53, 95% CI 2.00-10.27). However, polymer quantification approaches vary (particle counts vs polymer mass), contamination control is method-dependent, and inter-study comparability remains limited. The current evidence base supports aggressive exposure reduction as the most defensible \"first-line\" strategy. Nutritional approaches (dietary fiber, gut-barrier support, and microbiome modulation) are best framed as adjunctive, mechanistically plausible risk-mitigation strategies rather than proven methods to remove plastics from the body. Well-designed human trials and standardized analytical protocols are needed before clinical \"detoxification\" claims can be justified.","42434393":"ID: 42434393\nTitle: Metabolomic and Metagenomic Correlation Reveals the Network Regulatory Mechanism of Cecal Microbiota Structural Changes Induced by Eimeria tenella.\nAbstract: Eimeria tenella poses a significant threat to the poultry industry, and understanding the correlation between metabolic changes in cecal tissues and microbial community alterations is crucial for studying parasite-host interactions. To investigate the associations among dominant bacterial populations, key functional genes, and altered metabolites in cecal tissues and contents during E. tenella infection. Metagenomic analysis was first performed on cecal contents to identify the dominant bacterial communities, followed by metabolomic analysis of cecal tissues and contents. Correlation analysis was then conducted to evaluate the relationships among microbial communities, functional genes, and differential metabolites. Correlation analysis showed that increased potentially pathogenic genera were generally positively associated with upregulated metabolites and negatively associated with downregulated metabolites, whereas reduced commensal genera showed the opposite trend. Shared KEGG pathways co-enriched by differential metabolites and microbial functional genes were identified, mainly involving amino acid metabolism, transport systems, membrane-associated metabolism, and nucleotide metabolism. The metabolites linked to dominant bacterial communities were primarily enriched in pathways such as amino sugar metabolism, sialic acid metabolism, and glycerophospholipid metabolism. These findings reflected complex metabolic reprogramming and interactions between the host and pathogen, especially in cecal tissue repair, immune regulation, and metabolic competition with the pathogen. This study provided valuable insights into parasite-host interactions and laid a foundation for understanding the role of bacterial community-associated metabolites in cecal coccidiosis.","42434505":"ID: 42434505\nTitle: Metabolomic data of melittin-intervened murine cervical cancer cells based on liquid chromatography-mass spectrometry.\nAbstract: Melittin-treated murine cervical cancer U14 cells have been widely recognized as a classic cellular model for anti-tumor research in cervical cancer. This article contains metabolomic data of U14 cell lysates from both melittin-treated and control groups. Untargeted metabolomic profiling was carried out by liquid chromatography-mass spectrometry (LC-MS) to systematically elucidate the global metabolic disturbances in cervical cancer cells upon melittin intervention. LC-MS raw data were processed for peak extraction and alignment using XCMS software, followed by quality control normalization with metaX software. Metabolite annotation was performed against the HMDB and KEGG databases as well as an in-house MS/MS spectral library, yielding metabolite feature data including mass-to-charge ratio (m/z), retention time (RT), and MS/MS-identified metabolites (MS2). A total of 22,976 metabolic ions were detected in this study, among which 16,176 were assigned Level 1 annotations and 1114 were identified with high confidence at Level 2. All raw and processed data are publicly accessible at NGDC (accession number PRJCA065444). This untargeted LC-MS-based metabolomic dataset not only provides a comprehensive resource for elucidating metabolism-related anticancer mechanisms of melittin in murine U14 cervical cancer cells but also supports the development of targeted therapeutic strategies against cervical cancer.","42434548":"ID: 42434548\nTitle: Abdominal massage alleviates IBS-D by modulating the gut microbiota and suppressing the LPS/TLR4/NF-κB/MLCK pathway.\nAbstract: Diarrhea-predominant irritable bowel syndrome (IBS-D) is a common functional gastrointestinal disorder with complex and incompletely understood pathophysiology. This study aimed to investigate the therapeutic effects and underlying mechanisms of abdominal massage on diarrhea-predominant IBS-D using a rat model. IBS-D was induced in Sprague-Dawley rats through a combination of maternal separation and chronic stress. The experimental interventions consisted of abdominal massage and fecal microbiota transplantation (FMT) using donor microbiota obtained from IBS-D + abdominal massage rats. Assessments included fecal moisture content (FMC), Bristol stool scores, visceral hypersensitivity, intestinal motility, open field test, gut microbiota, short-chain fatty acids (SCFAs), inflammatory markers (LPS, TLR4/MyD88/NF-κB pathway), and intestinal barrier integrity (TEM, tight junction proteins, FITC-dextran permeability). Abdominal massage significantly improved diarrheal symptoms, visceral hypersensitivity, gastrointestinal motility, and anxiety-like behaviors in IBS-D rats. It restored gut microbiota diversity, reduced SCFA levels, and suppressed the TLR4/MyD88/NF-κB pathway, leading to decreased pro-inflammatory cytokines and LPS levels. FMT replicated these effects, suggesting the role of gut microbiota modulation. Moreover, abdominal massage also ameliorated barrier dysfunction in IBS-D rats by restoring ultrastructure, modulating MLCK and junctional proteins, and reducing macromolecular permeability. Abdominal massage alleviates IBS-D symptoms by modulating gut microbiota, inhibiting the TLR4/MyD88/NF-κB/MLCK signaling pathway, reducing inflammation, and restoring intestinal barrier function. These findings support its potential as a non-invasive therapeutic strategy for IBS-D.","42434567":"ID: 42434567\nTitle: Multi-omics reveal soil microbial dysbiosis and metabolite toxicity as drivers of blueberry continuous cropping obstacles.\nAbstract: Blueberry (Vaccinium spp.) are one of the most economically important fruit trees globally. However, due to continuous cropping have limited the industry's ability to produce consistently over the long term, and the mechanism underlying the development of this continuous cropping problem is not yet fully understood. In this study, we applied metagenomic and metabolomic to systematically detect changes in microbial community structure, function and metabolic profiles in rhizosphere and non-rhizosphere soils after different years of continuous blueberry cultivation (0, 2, 4, and 6 years) in Dalian (China). The results showed that continuous cultivation significantly reduced overall microbial diversity and the bacterial and fungal Shannon index, with the decrease being more significant in the rhizosphere soils (P < 0.05). The β diversity analysis showed that the microbial community structure was distinctly separated between cultivation periods, with the most prominent differences in the rhizosphere soils (PERMANOVA, P < 0.01). The increased cultivation duration led to a decrease in the relative abundance of beneficial functional taxa in the microbial community, while the depletion-tolerant and stress-adapted taxa were gradually enriched. Functional annotation analysis showed that KEGG pathways related to stress response, amino acid degradation, and energy metabolism significantly increased, while functions related to nutrient transformation and plant-microbe interactions were weakened (FDR < 0.05). The metabolomic results further showed that 6 years of continuous cultivation significantly reshaped the rhizosphere metabolite composition. This was evidenced by the accumulation of various secondary metabolites in the rhizosphere soil, including metabolites related to potential self-toxicity (e.g., ferulic acid, 3-hydroxyphenylacetic acid, and 2-hydroxycinnamic acid), mainly involved in the pathways of amino acid metabolism, lipid metabolism, and secondary metabolite synthesis. In conclusion, continuous cultivation of blueberry induced pronounced shifts in rhizosphere microbial community structure, function, and metabolite composition, suggesting that these changes may contribute to the development of continuous cropping obstacles (CCO).","42434798":"ID: 42434798\nTitle: The use of antibiotic, probiotic, and FMT in modulating Immunotherapy Efficacy and Survival: a systematic review and meta-analysis of clinical outcomes.\nAbstract: Immune checkpoint inhibitors (ICIs) have been one of the important therapeutic approaches for patients with advanced malignancies; nevertheless, their clinical efficacy remains limited in many patients. Recently, the contribution of intestinal microbiota to improved antitumor immune responses has gradually been recognized. A comprehensive literature search was conducted in PubMed, Embase, and the Cochrane Library to identify relevant studies published up to June 15, 2026. We evaluated the influence of microbiota interventions with respect to efficacy and survival in cancer patients receiving ICIs from three perspectives: antibiotics, probiotics, as well as fecal microbiota transplantation (FMT). The main endpoint was objective response rate (ORR), and secondary endpoints were overall survival (OS) and progression-free survival (PFS). The final analysis comprised 106 studies and categorized them into three groups: antibiotics (76 studies), probiotics (15 studies), and FMT (15 studies). Antibiotic use was correlated with compromised immunotherapy efficacy and unfavorable survival outcomes. In particular, antibiotics exposure was linked to a reduced ORR (Odds Ratio, OR = 0.60, 95% Confidence Interval, CI = 0.46-0.77, p < 0.001), shorter OS (Hazard Ratio, HR = 1.56, 95% CI = 1.44-1.69, p < 0.001), and shorter PFS (HR = 1.50, 95% CI = 1.32-1.70, p < 0.001). In contrast, probiotics showed a supportive and positive effect on immunotherapy outcomes, with improved ORR (OR = 1.95, 95% CI = 1.46- 2.62, p < 0.001) and better OS (HR = 0.56, 95% CI = 0.41- 0.78, p < 0.001) and PFS (HR = 0.53, 95% CI = 0.38-0.74, p < 0.001). FMT combined with immunotherapy achieved a favorable ORR of 0.30 (95% CI = 0.16-0.45, p < 0.001). This meta-analysis synthesized evidence from studies on antibiotics, probiotics, and FMT use, suggesting gut microbiota offering potential approaches to enhance immunotherapy treatment effectiveness and clinical efficacy in individuals with advanced-stage solid cancers.","42434881":"ID: 42434881\nTitle: Synergistic effects of chitin and nitric oxide on phytochemical and molecular defense mechanisms in Andrographis paniculata under nickel stress.\nAbstract: Nickel (Ni) contamination is an increasing environmental concern that negatively affects plant growth, physiological performance, and the biosynthesis of medicinally important secondary metabolites. The use of natural biostimulants such as chitin and nitric oxide (NO) has emerged as a promising strategy to enhance plant tolerance against heavy metal stress. Therefore, this study investigated the potential of chitin and NO to enhance the physiological and phytochemical responses of Andrographis paniculata under Ni stress. The study was designed to assess the effects of varying concentrations of chitin (0, 15, and 30 µM) and NO (0, 0.5, and 1 g/L) on several growth parameters, including photosynthetic pigments, total phenolic content, total flavonoid content, protein accumulation, key secondary metabolites (andrographolide, neoandrographolide, and 14-deoxy-11,12-didehydroandrographolide), and the expression of isoprenoid biosynthesis-related genes (HMGR, HMGS, DXR, and DXS) in A. paniculata under different levels of Ni stress (0, 1.5, and 3 mM). The results showed that Ni stress significantly reduced chlorophyll, carotenoid, phenolic, and protein contents, whereas it altered secondary metabolite profiles and gene expression patterns. Application of NO and chitin significantly improved chlorophyll a, chlorophyll b, carotenoids, total phenols, and protein content under Ni stress conditions. In addition, NO and chitin treatments enhanced the accumulation of key bioactive compounds and positively regulated the expression of genes involved in terpenoid biosynthesis pathways. Overall, the findings indicate that NO and chitin alleviate Ni-induced stress in A. paniculata primarily through improving physiological performance and enhancing the accumulation of non-enzymatic antioxidant compounds such as phenolics and flavonoids, thereby contributing to improved metabolic stability and secondary metabolite production under heavy metal stress. Andrographis paniculata emerges as a valuable medicinal-industrial species with diverse pharmaceutical applicationsChitin-nitric oxide synergy significantly boosts nickel stress tolerance and phytochemical production in A. paniculataNickel stress upregulates terpenoid biosynthesis genes (HMGS, HMGR, DXS, DXR), amplified by chitin-NO elicitation.","42434935":"ID: 42434935\nTitle: Christensenella massiliensis reduces kynurenine levels and alleviates obesity and related metabolic disorders in model mice.\nAbstract: Next-generation probiotics derived from gut commensals show promise for metabolic disease intervention, yet effective anti-obesity strains remain limited. Here, we demonstrate that oral administration of Christensenella massiliensis markedly alleviates obesity and metabolic dysfunction in high-fat diet-induced obese mice. Treatment reduced food intake, improved glucose tolerance and insulin sensitivity, lowered blood glucose and lipid levels, and attenuated hepatic steatosis and adipose accumulation. C. massiliensis increased the levels of plasma GLP-1 and ileal GLP-1 receptor expression while decreasing ghrelin level, suggesting modulation of gut hormone regulation. C. massiliensis also suppressed systemic and colonic inflammation, accompanied by upregulation of metabolic homeostasis-related genes (ppara, pparg, ucp2). Targeted and quantitative metabolomics identified altered gut metabolic profiles, particularly reduced kynurenine levels. In vitro assays further showed that C. massiliensis converted kynurenine into kynurenic acid, and its lysate reversed kynurenine-induced lipid accumulation, inflammation, and PPARγ suppression in hepatocytes, providing mechanistic support for the observed in vivo metabolic benefits. These findings support C. massiliensis as a promising next-generation probiotic for obesity management.","42435068":"ID: 42435068\nTitle: Tandem-sgRNA Provides an Effective Reverse Genetic Approach for Suppression of Streptomyces Biosynthetic Gene Clusters and Secondary Metabolism.\nAbstract: Bacterial biosynthetic gene clusters (BGCs) encode secondary metabolites with diverse biological activities; however, most BGC products remain uncharacterized. One approach to identifying products and their metabolism is to use reverse genetics to identify metabolite-associated phenotypes. CRISPR interference (CRISPRi) offers a promising approach to disrupt BGC functions in high-GC genomes, typical of Streptomyces species. In many of these organisms, single-guide RNA (sgRNA)-mediated CRISPRi often results in incomplete product suppression, resulting in partial phenotypes that are unsuitable for functional studies. Using Streptomyces sp. Mg1, we found that a tandem-sgRNA configuration for CRISPRi improved the efficiency of target metabolite suppression. We engineered strains to express two sgRNAs to target the same promoter region within a BGC, resulting in greater than 80% metabolite suppression across diverse secondary metabolite classes. We used tandem-sgRNA CRISPRi to identify phenotypes associated with the loss of polyketide linearmycins, the siderophore desferrioxamine, the terpene β-carotene, and an uncharacterized nonribosomal peptide synthetase (NRPS). This approach revealed that β-carotene depletion substantially reduced intrinsic cellular autofluorescence. Targeting the unknown NRPS produced developmental phenotypes and enabled the identification of the biosynthetic genes for the antibiotic lavendomycin, revealing a noncollinear organization of genes in the BGC. We suggest that tandem-sgRNA CRISPRi provides an efficient reverse genetics platform for the functional characterization of Streptomyces BGCs, enabling the correlation of metabolites with the gene function, identification of associated phenotypes, and prioritization of cryptic BGCs for natural product discovery.","42435073":"ID: 42435073\nTitle: SigMine and OPathDb: a literature-mining pipeline and database of potential opportunistic pathogens.\nAbstract: Conversion of unstructured biomedical literature into structured knowledge for identifying cross-domain associations between biological entities remains a challenging task.

SigMine performs biomedical entity recognition from PMC articles using the EuropePMC Annotation API. Advanced entity recognition was performed using Python scripting, NCBI E-Utilities, and an n-gram algorithm followed by extensive data cleaning and mapping against standard databases. Statistical evaluation identified significantly co-occurring entities. The entire workflow was automated through a modular framework developed in Python v3.13 with a Tkinter-based Graphical User Interface. SigMine enhances usability while retaining the flexibility to use new dictionaries for annotation. SigMine was used to construct a literature-derived potential human Opportunistic Pathogens Database (OPathDb), housing 5,626 potential opportunistic pathogens significantly co-occurring with 1440 diseases and 7121 genes mined from 25,000 PMC articles. Additional annotation of 598 significantly co-occurring metabolites and 30 affected tissues is available for 3204 and 227 pathogens, respectively. OpathDb has a user-friendly query interface searchable by organism, disease, tissue, gene, protein and metabolite available at https://www.opathdb.cbsblab-nsut.in . Organism-entity associations can be visualized as weighted networks, with color-coded nodes and significance-scaled edges. Significant associations of opportunistic pathogens like Akkermansia mucinifila with colorectal cancer and Segatella copri with glucose intolerance can be identified through OpathDb. Through this database, the SigMine framework demonstrates conversion of unstructured text in vast and heterogenous corpora into standardized and well-organized information.

MPL diet significantly reduced body weight gain, adiposity, and hepatic lipid accumulation, in addition to decreasing serum levels of liver injury markers. Mechanistically, MPL diet activated hepatic Wnt/β-catenin signaling, as evidenced by increased expression of low-density lipoprotein receptor-related protein 6 (LRP6), Wnt family member 3 A (Wnt3a), and β-catenin. Concurrently, MPL treatment suppressed peroxisome proliferator-activated receptor gamma (PPARγ) and downstream lipogenic proteins involved in triglyceride synthesis and de novo lipogenesis. In addition, MPL diet markedly reshaped the gut microbiota composition disrupted by HFHS feeding. Notably, MPL group showed a significant increased the abundance of Akkermansia muciniphila and short-chain fatty acid-producing bacteria, including members of Romboutsia and Christensenellaceae. These findings demonstrate that dietary MPL effectively attenuates HFHS diet-induced NAFLD through coordinated regulation of hepatic Wnt-PPARγ signaling and gut microbial ecology.","42435165":"ID: 42435165\nTitle: The Interdependence of Carbon Substrates and Metabolic Pathways Enables the Metabolic Plasticity of Cancer Cells.\nAbstract: The tumor microenvironment (TME) functions as a dynamic and co-evolving ecosystem, where malignant and non-malignant cells form a metabolically interdependent community. This ecological view reimagines tumors not as isolated cell masses, but as complex biotopes in which cellular interactions are integral to tumor initiation, growth, and progression. A hallmark of this adaptive environment is metabolic plasticity-an essential mechanism that enables tumor cells, including the metastatic ones, to reprogram their metabolism in response to fluctuating nutrient availability and environmental stressors. At the core of this reprogramming lies carbon metabolism, characterized by the selective and flexible utilization of key metabolites, including glucose, lactate, glutamine, cysteine, and fatty acids. These compounds support energy production, biomass synthesis, and redox balance, while also facilitating the export and repurposing of metabolic byproducts for signaling or reuse. This chapter presents a conceptual framework that explores the interdependence of central metabolic pathways, emphasizing how tumors coordinate energy generation, biosynthesis, and redox control to support malignant progression.","42435167":"ID: 42435167\nTitle: Metabolism-Driven Modulation by the Human Microbiota: Implications for Cancer Therapy and Emerging Strategies.\nAbstract: The human microbiome plays a pivotal role in cancer development, progression, and therapeutic response. Epidemiologic studies have established links between microbiome composition and various malignancies, with specific microbial taxa exerting direct carcinogenic effects or influencing tumorigenesis through metabolite production and immune modulation. While the gut microbiome remains the most extensively studied, emerging evidence highlights the significance of microbiomes in other body sites, including the cervix, lung, and skin, which also modulate cancer risk and progression. These site-specific microbial communities interact with local factors, such as human papillomavirus in the cervix or inflammatory pathways in the lung and skin, contributing to carcinogenesis. Importantly, distinct microbial signatures across these niches serve as promising noninvasive biomarkers for early cancer detection and prognosis, offering improved accessibility and patient compliance compared to traditional methods. Additionally, the gut microbiome influences anticancer therapeutic outcomes, suggesting that metabolism-based interventions targeting microbial-host interactions may enhance treatment efficacy. Integrating microbiome research into oncology presents novel opportunities for advancing personalized cancer prevention, diagnosis, and therapy.","42435168":"ID: 42435168\nTitle: Gut-Liver Microbiome and Tumor Microenvironment in Metabolic Dysfunction-Associated Steatotic Liver Disease.\nAbstract: Hepatocellular carcinoma (HCC), the dominant form of primary liver cancer associated with cirrhosis, has been increasing in prevalence in the US and globally. Metabolic dysfunction-associated steatotic liver disease (MASLD), which is linked to the obesity pandemic and growing prevalence of metabolic disorders, has played a major role in this worrisome trend. Notably, up to 50% of MASLD-associated HCC develop in the noncirrhotic liver, suggesting different mechanisms of carcinogenesis as compared to HCC associated with other chronic liver diseases and potentially resulting in delays in diagnosis. Unfortunately, HCC has an unfavorable prognosis once advanced, and systemic therapies used in the management of advanced HCC have limited efficacy and considerable toxicity. More insight into HCC pathophysiology is therefore urgently needed to improve both preventive and therapeutic strategies. The gut-liver axis, and specifically the gut microbiome, appears to play a major role in the development and progression of HCC. MASLD is associated with dysbiosis, and HCC is a serious outcome of a dysfunctional relationship between the liver and the gut microbiome. Microbial-derived metabolites and cell wall components, which reach the liver via the portal and biliary circulation, may have direct oncogenic effects or activate pathways of cell proliferation, inflammation, and immunosuppression, thus altering the liver tumor microenvironment. In addition, the recent discovery of the intratumoral microbiome offers novel opportunities to learn about the host-microbiome relationship, hepatocarcinogenesis, and tumor surveillance. Further insight into the dysfunctional gut-liver axis and immuno-oncology-microbiome axis in MASLD promises to advance strategies for HCC prevention and treatment.","42435173":"ID: 42435173\nTitle: Epigenetics and One-Carbon Metabolism in Cancer: Mechanisms and Therapeutic Implications.\nAbstract: Epigenetics refers to heritable changes in gene expression that occur without alterations in the DNA sequence itself, primarily through mechanisms such as DNA methylation and histone modifications. These regulatory processes are essential for normal development, cellular differentiation, and genome stability. In cancer, however, epigenetic reprogramming becomes dysregulated, contributing to tumor initiation, progression, and metastasis. Aberrant DNA methylation patterns and histone modifications can silence tumor suppressor genes or activate oncogenes, driving malignant transformation. Central to these epigenetic processes is one-carbon metabolism-a biochemical network that supplies methyl groups for DNA and histone methylation through metabolites such as S-adenosylmethionine (SAM). As such, the interplay between one-carbon metabolism and epigenetic regulation is a critical axis in understanding and potentially targeting cancer biology.","42435219":"ID: 42435219\nTitle: The slow component of the [Formula: see text] response is associated with the increase in glycolytic contribution.\nAbstract: After approximately 2 min of severe intensity exercise, there is a delayed increase in oxygen uptake (V̇O2). It has been hypothesized that this slow component may be in response to an increase in glycolytic contribution, which causes a progressive recruitment of less-efficient Type II fibers. We examined whether the area under the curve of the V̇O2 slow component (AUCslow) is associated with glycolytic contribution during severe intensity constant-power cycling. Seven women and 13 men completed three constant-power cycle tests terminated at 3, 6, or 9 min in randomized order. The kinetics of the V̇O2 response was modelled using iterative regression, and AUCslow was calculated. Glycolysis contribution was estimated from peak post-exercise blood lactate. Pearson correlations assessed associations at each duration. AUCslow was 2 ± 1 mL·kg⁻1 in 0-3 min of exercise; there was an additional 8 ± 3 mL·kg⁻1 in min 3-6 and an additional 4 ± 3 mL·kg⁻1 in min 6-9. Glycolysis contribution was 18 ± 7 mL·kg⁻1 in min 0-3, an additional 6 ± 2 mL·kg⁻1 in min 3-6, and an additional 2 ± 1 mL·kg⁻1 in min 6-9. Correlation values for AUCslow and glycolytic contribution were strong (r = 0.69, p < 0.01 for 3-6 min; and r = 0.75, p < 0.01 for 6-9 min). AUCslow is related to glycolytic contribution after 3 min of severe intensity exercise. We speculate this is due to an increase in Type II fiber recruitment to compensate for fatiguing active fibers due to the accumulation of glycolytic metabolites.","42435223":"ID: 42435223\nTitle: Back to the roots: Cannabis sativa L. root metabolism, microbiomes, and biotechnological potential.\nAbstract: Cannabis sativa L. roots have been less studied than aboveground organs, despite their key role in plant physiology, metabolism, and interactions with biotic and abiotic factors. Metabolomic and phytochemical analyses reveal that roots synthesize a diverse array of bioactive compounds with antimicrobial, anti-inflammatory, antioxidant, and cytotoxic properties, highlighting their biotechnological potential. Root exudation patterns and interactions with endophytic microorganisms modulate rhizosphere microbial networks that support nutrient uptake, stress tolerance, pathogen resistance, and whole-plant physiology. Root-derived phytohormones and other signalling molecules may participate in coordinating biochemical pathways between belowground and aboveground tissues, with potential effects on secondary metabolism in aerial tissues. Recent advances in metabolomics, transcriptomics, microfluidic rhizosphere systems, and root-specific genetic engineering now enable detailed investigation of root metabolism in Cannabis sativa L. This review synthesises current knowledge on the metabolic roles of Cannabis sativa L. roots, their interactions with the rhizosphere microbiome, and root-derived systemic signalling. It emphasises aspects of root biology that are central to fundamental plant processes and to the development of sustainable strategies for optimising phytochemical yields. By placing roots at the forefront, this synthesis underscores the need to expand research beyond aerial tissues to fully understand and harness the biotechnological potential of Cannabis species. KEY POINTS: • Root metabolism and signalling regulate whole-plant-metabolic pathways • Root-associated microbiomes influence nutrient dynamics and phytochemical profiles • Root culture systems provide a scalable platform for biotechnological manipulation aimed at the production of bioactive compounds.","42435238":"ID: 42435238\nTitle: A machine learning approach to metabolomics identifies putative biomarker candidates and dysregulated pathways for distinguishing gout from asymptomatic hyperuricemia in the Zhuang population.\nAbstract: Gout typically develops from hyperuricemia (HUA), but the metabolic alterations driving this transition remain poorly understood, limiting our understanding of disease pathogenesis. To identify stage-specific putative biomarker candidates and to characterize dysregulated metabolic pathways distinguishing gout from HUA. We conducted a targeted metabolomics assay on the baseline plasma samples from a Zhuang minority cohort using LC-MS/MS. The analyzed sample set comprised 38 HUA patients, 47 gout patients, and 52 healthy controls. Sex-stratified differential metabolite analysis was performed across all participants, as well as in female and male subgroups. Pathway enrichment analysis was carried out using the KEGG database. Machine learning approaches, including the Boruta algorithm and support vector machine (SVM), were employed for putative biomarker discovery and model evaluation in male participants. Among all participants, 24 metabolites reached nominal significance (P < 0.05), but only uric acid remained significant after FDR correction. In sex-stratified analyses, no metabolite survived FDR correction in females, whereas in males, seven metabolites (flavone, glutamine, L-2-aminoadipic acid, L-pipecolic acid, N1-methyl-2-pyridone-5-carboxamide, phenyllactic acid, and uric acid) showed significant differences among healthy controls, HUA patients, and gout patients (FDR < 0.1). These metabolites were primarily involved in nitrogen metabolism, arginine biosynthesis, D-amino acid metabolism, nicotinate and nicotinamide metabolism, and purine metabolism. Machine learning identified four metabolites (N1-methyl-2-pyridone-5-carboxamide, flavone, glutamine, and phenyllactic acid) that distinguished gout from healthy controls, with AUCs of 0.902 and 0.800 in the training and validation sets, respectively. A second model (L-pipecolic acid, glutamine, phenyllactic acid, and flavone) discriminated gout from HUA, achieving AUCs of 0.850 and 1.000. Sensitivity analyses excluding obese or hypertriglyceridemic participants confirmed the robust performance of both models. This study suggests sex-specific metabolic alterations in gout and provides robust machine learning-based models for male participants. The identified metabolite signatures appear to extend purine metabolism to involve amino acid and energy metabolic pathways. These findings provide a basis for mechanism-targeted strategies in HUA management. External validation remains essential.","42435267":"ID: 42435267\nTitle: A metabolomic signatures in hyperuricemia: a systematic review.\nAbstract: Hyperuricemia (HUA) is traditionally viewed as a disorder of purine metabolism. However, its broader metabolic alterations remain incompletely understood. Metabolomics provides a useful approach for exploring metabolite changes associated with HUA, but a comprehensive synthesis of existing findings is still lacking. This systematic review and meta-analysis aimed to characterize the systemic metabolic signature of HUA beyond purine pathways. By synthesizing data from 27 metabolomics studies involving 12,335 participants, the study sought to identify consistent metabolite biomarkers and key dysregulated pathways to provide new insights for diagnosis and therapeutic targeting. This review included 27 metabolomics studies involving 12,335 participants and identified 1,187 metabolites reported in association with HUA. Qualitative synthesis showed 54 consistently elevated and 20 consistently decreased blood metabolites, mainly involving amino acids, lipid-related metabolites, energy-related compounds, vitamins and their derivatives, and purine nucleoside metabolites. The meta-analysis was limited to two eligible studies, with one study contributing most of the statistical weight; it suggested higher levels of Alanine, Leucine, Phenylalanine, and Tyrosine and lower Histidine levels in HUA. Pathway enrichment analysis highlighted \"One carbon pool by folate,\" \"Arginine biosynthesis,\" \"Glutathione metabolism,\" and related amino acid and energy metabolism pathways. Overall, these findings suggest that HUA may be associated with metabolic perturbations beyond purine metabolism alone, but the candidate metabolites and pathways require further validation in longitudinal, standardized, and mechanistic studies.","42435313":"ID: 42435313\nTitle: Haematococcus pluvialis peptides ameliorated cyclophosphamide-induced immunodeficiency in mice by regulating intestinal barrier function.\nAbstract: Immunodeficiency is a pathological state characterized by impaired functional integrity of the immune system, which contributes to the development of various diseases. Natural bioactive peptides are a promising option for improving immune function. This study examined the therapeutic effects and underlying mechanisms of Haematococcus pluvialis peptides (HPP) against CTX-induced immunodeficiency in mice. The results demonstrated that HPP increased bodyweight, immune organ indices, and blood cell count - white blood cells (WBC), red blood cells (RBC), platelets (PLT), hemoglobin (HGB), lymphocytes (Lym), and granulocytes (Gran), as well as serum cytokine levels (interferon-gamma (IFN-γ), interleukin-2 (IL-2), and immunoglobulin A (IgA) - in immunodeficient mice. Haematococcus pluvialis peptides improved the villus length and crypt depth of the small intestine and increased intestinal levels of superoxide dismutase (SOD), glutathione peroxidase (GSH-PX), and secretory immunoglobulin A (SIgA). Colonic levels of tight junction proteins - zonula occludens-1 (ZO-1) and occludin - were up-regulated. Fecal microbiota analysis suggested that HPP promoted the enrichment of beneficial bacterial genera (Ligilactobacillus, norank_f_Muribaculaceae, Alistipes) and suppressed pathogenic bacteria (Escherichia-Shigella and Klebsiella). Gut microbial metabolites analysis showed that HPP altered various fecal metabolites involved in lipids and lipid-like molecules, organoheterocyclic compounds, phenylpropanoids and polyketides, as well as organic acids and their derivatives. Fecal microbiota transplantation (FMT) experiments also validated the decisive role of gut microbiota in the immunomodulatory function of HPP. These results offer novel insights into the protective efficacy and underlying mechanisms of HPP for alleviating immunodeficiency, establishing a robust theoretical basis for its application as a promising immunomodulatory agent. © 2026 Society of Chemical Industry.","42435434":"ID: 42435434\nTitle: Molecular networking-guided discovery of cytotoxic metabolites in Humiria balsamifera: insights into Bergenin selectivity and safety.\nAbstract: This study investigated the chemical composition and cytotoxic activity of Humiria balsamifera St. (Aubl.) Hill. Extracts obtained with ethyl acetate, methanol, and ethanol were analysed by UHPLC-QTOF-MS molecular networking, and statistical analysis, revealing 18 metabolites in positive mode. Multivariate analyses showed that plant organ and extraction solvent strongly shaped metabolite profiles, identifying bioactive markers with biological relevance. Bergenin was isolated from the ethyl acetate extract of the stem. The in vitro cytotoxicity screening in human colorectal carcinoma cells (HCT-116) demonstrated that the isolated compounds exhibited inhibition greater than 75%, while the crude extracts were less effective. Bergenin, also evaluated in mammary adenocarcinoma cell lines (MCF-7 and MDAMB231) and non-tumour cells (RPE-1), did not inhibit the growth of cancer cells but showed low toxicity in healthy cells. The analysis of the identified metabolites suggests the potential of the species as a source of bioactive compounds. The selectivity of the antiproliferative effect of the isolates in HCT-116 and the safety of bergenin in non-tumour cells indicate the need for future investigations to elucidate their mechanisms of action and explore their therapeutic potential, as well as to identify other relevant compounds.","42435486":"ID: 42435486\nTitle: Metabolite-driven epigenetic modifications remodel immune cell functions in COPD: From Lactylation to Succinylation.\nAbstract: Chronic obstructive pulmonary disease (COPD) is characterized by persistent airway inflammation, progressive immune dysfunction, and irreversible structural remodeling. Although cigarette smoke-induced oxidative stress has long been recognized as the predominant pathogenic driver, conventional inflammatory theories fail to fully account for the sustained inflammatory state that persists even after smoking cessation. Accumulating evidence indicates that COPD is governed by a metabolite-centered epigenetic regulatory network. Intracellular metabolic intermediates function not only as substrates for energy metabolism, but also as signaling molecules that directly modulate chromatin architecture and transcriptional programs. In this context, metabolic reprogramming emerges as a pivotal determinant of immune cell fate and inflammatory memory formation. This review systematically summarizes recent research advances in the \"metabolite-redox-epigenetics\" axis in COPD. We specifically discuss histone lactylation as a glycolysis-dependent inflammatory amplification mechanism and propose that histone succinylation represents a redox-sensitive epigenetic mechanism linked to mitochondrial dysfunction, bridging tricarboxylic acid (TCA) cycle dysregulation and persistent immune activation. We further integrate acetylation, crotonylation, β-hydroxybutyrylation, DNA methylation, and RNA m6A modification to construct a unified immunometabolic regulatory network. We propose that COPD is essentially a metabolically imprinted inflammatory memory disease, whose core mechanism resides in the chronic oxidative stress-triggered persistent remodeling of chromatin accessibility, which stably enforces pathogenic immune phenotypes. Targeting metabolite-driven epigenetic remodeling may offer novel therapeutic strategies to reverse chronic inflammatory memory and restore immune homeostasis. Recent evidence further suggests that cGAS-STING-mediated mitochondrial DNA sensing, inflammasome-dependent pyroptosis, gut-lung axis-derived metabolites, and AMPK/SIRT1/PGC-1α signaling may provide additional links between metabolic stress, epithelial injury, and immune dysfunction.","42435492":"ID: 42435492\nTitle: Toxicological evaluation of benzophenone-3 and its metabolite benzophenone-1 in TM3 Leydig cells.\nAbstract: Recently, a decline in male fertility has been reported, raising concerns about the role of environmental pollutants. Ultraviolet (UV) filters have attracted attention due to their potential effects. Benzophenone-3 (BP-3) is a widely used UV filter. It is frequently detected in environmental and human biomonitoring studies, indicating widespread exposure. After dermal absorption, BP-3 enters systemic circulation and is metabolized to benzophenone-1 (BP-1). Although both compounds have been reported to exhibit endocrine-active properties, including antiandrogenic effects, toxicological data on BP-1 are still limited. Therefore, the potential effects of benzophenone derivatives on Leydig cell function and male reproductive health require further investigation. We aimed to evaluate the potential cytotoxic and genotoxic effects of BP-3 and BP-1 in TM3 mouse Leydig cells. Cytotoxicity was assessed using the MTT (3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide) and neutral red uptake assays. DNA damage was evaluated using the alkaline comet assay. Reactive oxygen species (ROS) production was determined using a DCFDA/H2DCFDA-based assay, and testosterone levels were measured using an enzyme-linked immunosorbent assay (ELISA). Exposure to both compounds resulted in concentration-dependent reductions in cell viability, with a more pronounced decrease for BP-1. BP-1 increased ROS formation at selected concentrations, whereas BP-3 did not induce oxidative response. Assessment of DNA integrity using the comet assay did not reveal measurable DNA damage. Under experimental conditions without hormonal stimulation, no statistically significant difference in testosterone concentrations was observed. The findings indicate BP-1 may exert stronger cytotoxic and oxidative effects than BP-3 in Leydig cells, suggesting that metabolites may contribute to the overall toxicological profile of UV filters in reproductive toxicity evaluations.","42435543":"ID: 42435543\nTitle: Non-targeted metabolomics reveals differential distribution of flavonoids and organic acids between mesophyll and vein tissues in Synotis solidaginea leaves with AFADESI-MSI confirmation.\nAbstract: Synotis solidaginea Hand.-Mazz. (SSD), a traditional Tibetan medicinal plant utilized for heat-clearing and wound healing, contains organic acids and flavonoids as primary bioactive components. This study aimed to investigate the differential distribution of flavonoids and organic acids between mesophyll and vein tissues in SSD leaves using non-targeted metabolomics with AFADESI-MSI confirmation. Non-targeted metabolomics using ultra-performance liquid chromatography-quadrupole Exactive HF-X (UPLC-Q Exactive™ HF-X) was employed to analyze chemical composition differences between mesophyll (YR) and vein (YM) tissues. Flavonoids and organic acids were analyzed separately as key compound classes. Air flow-assisted desorption electrospray ionization mass spectrometry imaging (AFADESI-MSI) was used to confirm and visualize the spatial distribution of representative metabolites. Multivariate statistical analyses including principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA) were performed to identify tissue-specific signatures. The non-targeted metabolomics analysis identified a total of 2984 metabolites, among which 899 exhibited significant differential accumulation between the two tissue types. Organic acids and their derivatives constituted the largest proportion (50.7%) of these differential metabolites. Specifically, the bioactive flavonoids quercetin and gossypetin showed a 7.8-fold higher accumulation in the veins, whereas homoeriodictyol exhibited a 10.22-fold enrichment in the mesophyll. Regarding organic acids, gallic acid C was highly concentrated in the mesophyll (37.65-fold higher), whereas 4-hydroxycinnamic acid and maleic acid were significantly enriched in the veins. Crucially, AFADESI-MSI successfully confirmed the highly compartmentalized spatial distribution patterns of 14 key metabolites. This study revealed distinct tissue-specific distribution patterns of flavonoids and organic acids in SSD leaves. The combination of non-targeted metabolomics with AFADESI-MSI confirmation provides a robust analytical framework for understanding chemical distribution in traditional medicinal plants, offering insights for quality control and targeted extraction strategies.","42435608":"ID: 42435608\nTitle: Yolk metabolomics reveals candidate compounds associated with egg specific density and hatchability in white layer breeder hens.\nAbstract: The present study aimed to evaluate the influence of egg geometry, weight loss, and specific density (SD) on hatchability in older white layer breeder hens. In addition, based on the positive correlation observed between fertility and egg SD, we hypothesized that the mineral and metabolomic composition of the yolk may be associated with specific density. A total of 8,874 eggs from five Lohmann LSL Lite breeder flocks (52-64 weeks) were analyzed. We found that digital image analysis is an adequate method for evaluating the egg shape index, whereas Archimedes' principle is suitable for determining SD. Although we observed an influence of shape index and weight loss on hatchability, the clearest findings were related to SD. Eggs within the upper 50% SD range (1075-1110g/L) exhibited higher hatchability than those with lower SD, primarily due to reduced infertility and lower early embryonic mortality. Low-SD eggs showed increased contamination rates. Yolk mineral concentrations did not differ significantly between SD groups, except for the Na:K ratio. However, the N;Ka ratio showed minimal predictive value, indicating that mineral composition alone has limited explanatory power for eggshell density. Untargeted metabolomics identified 310 metabolites in yolk, but only melatonin glucuronide and dihydroxytetradecanoic acid met the significance criteria (p<0.05; fold change > 2). This study provides a precise way to evaluate egg geometry and SD. Furthermore, using a large dataset, it demonstrates that eggs with low SD have reduced hatchability due to infertility and early mortality, likely linked to contamination. Although the Na:K ratio, melatonin glucuronide, and dihydroxytetradecanoic acid showed limited predictive performance when evaluated individually, their identification highlights potential biochemical differences associated with SD and supports their further investigation as candidate markers.","42435668":"ID: 42435668\nTitle: Mechanism of seaweed polyphenols interacting with intestinal flora to regulate blood glucose.\nAbstract: Seaweed polyphenols possess hypoglycemic biological functions, but the specific mechanisms remain unclear, which limits their further application. In this study, the area under the blood glucose curve (AUC) of the fourth-period Porphyra haitanensis polyphenols extract (FPPE)-fed mice was significantly reduced by 17.12 ± 0.87%. Moreover, FPPE exhibited α-glucosidase inhibitory activity at 64.39 ± 4.05%. In vitro fermentation experiments showed that FPPE modulated the composition of the gut microbiota, thereby enhancing the production of short-chain fatty acids (SCFAs). Analysis of intestinal flora and metabolites in mice revealed that FPPE selectively enriched hypoglycemic-functional bacteria, such as Bacteroides and Alloprevotella. These bacteria feedback-regulated the production of hypoglycemic polyphenolic substances such as isovitexin and isoquercetin, which showed a strong positive correlation. Further mechanistic studies revealed that FPPE's digest could suppress cellular glucose transport by inhibiting the expression of Sodium Glucose Cotransporter 1 (SGLT1) and glucose transporter 2 (GLUT2), thereby reducing blood glucose levels.","42435783":"ID: 42435783\nTitle: CYP450 Network Shifts in MASLD/MASH: From Pathogenesis to Nutrition-Informed Modulation.\nAbstract: As MASLD/MASH becomes increasingly prevalent in parallel with obesity, metabolic dysfunction, and ultra-processed dietary patterns, understanding how diet-related exposures influence hepatic drug-metabolizing and lipid-metabolizing pathways has become clinically relevant. CYP450 enzymes represent a key interface between metabolic stress, xenobiotic handling, oxidative injury, and nutrition-related exposures, yet their role in MASLD/MASH has not been fully integrated from a nutrition-informed perspective. This review maps nutrition-exposure-CYP relationships across MASLD/MASH by integrating dietary patterns, food-processing exposures, contaminants/additives, and bioactive compounds within a structured qualitative framework. The reviewed evidence suggests that obesity, high-fat diet exposure, fructose co-exposure, and fatty acid composition may reshape hepatic CYP responses through isoform-, exposure-, and endpoint-dependent mechanisms. Human liver tissue and microsome studies provide relatively stronger translational evidence for altered CYP3A4 expression, activity, and clearance in NAFLD/NASH, whereas evidence for many nutrition-related exposures remains primarily animal-based, in vitro, or mechanistic. Macronutrient-related pathways, including fructose with high-fat intake and omega-6/omega-3 oxylipin imbalance, appear to influence CYP-mediated lipid and inflammatory signaling. Food-derived contaminants such as nitrosamines, aflatoxin B1, and acrylamide provide biologically plausible examples of CYP-dependent bioactivation in metabolically vulnerable liver contexts, although direct human MASLD/MASH validation remains limited. Evidence for food additives and phytochemicals is more preliminary and should be interpreted mainly as hypothesis-generating rather than clinically established. Across the reviewed evidence, metabolic inflammation appears to favor pro-oxidant CYP pathways, including CYP2E1 and CYP4A/4F, while suppressing or altering detoxification and epoxygenase-related pathways, including CYP3A and CYP2C/2J. However, changes in CYP expression do not necessarily translate into altered enzymatic activity or clinical clearance. We conclude that nutrition-related CYP remodeling may represent a mechanistic and translational interface linking diet, oxidative injury, xenobiotic handling, and MASLD/MASH progression. Future studies should integrate dietary exposure assessment with CYP activity or clearance phenotypes, oxidative stress biomarkers, gut-liver axis markers, and MASLD/MASH stage-specific clinical outcomes.","42435809":"ID: 42435809\nTitle: A Targeted Analysis of The Donor Human Milk Metabolome & Implications for Preterm Infant Nutrition.\nAbstract: Donor human milk (DHM) is widely used for preterm infants when mother's own milk (MOM) is unavailable, yet its metabolome is poorly described. To profile the metabolome of pooled, pasteurized DHM obtained from a single milk bank over a one-year period and compare it to human milk (HM) from reference cohorts. Pooled DHM (n=47) was collected weekly from the Mother's Milk Bank of Florida over 47 consecutive weeks from July 2022 to June 2023. Using 1H-NMR spectroscopy, we quantified 59 polar metabolites in DHM and compared the metabolomic profile with previously published data on HM from mothers of preterm (n=29) and term (n=97) infants collected across the first 3 months postpartum and analyzed using identical methods. Variability and group differences were assessed with regression, linear mixed-effects models, PCA, and PERMANOVA; p-values were FDR-adjusted. DHM showed limited variability, as the coefficient of variation for nearly half of the metabolites was 20-30%. Compared with both preterm and term colostrum and transitional milk, DHM had lower acetylcarnitine, myo-inositol, 3'-sialyllactose, and 6'-sialyllactose (FDR-adjusted p-value < 0.1). PCA separated HM by lactation stage and delivery type, with DHM clustering closest to term HM at 3 months postpartum and farthest from preterm colostrum. PERMANOVA and dispersion testing indicated that DHM differed significantly from all HM groups (FDR-adjusted p-value < 0.1), reflecting compositional differences related to lactation stage and reduced heterogeneity from pooling. While DHM is the preferred alternative to MOM for preterm infants, it contains lower concentrations of several potentially important metabolites than preterm HM, which may be further diluted by fortification. Future studies should evaluate how these differences and fortification may affect infant growth, development, and long-term outcomes.","42435811":"ID: 42435811\nTitle: A classification model for predicting corticosteroid and cyclosporin: A responsiveness in pediatric idiopathic uveitis.\nAbstract: To identify serum metabolic biomarkers that distinguish corticosteroid and cyclosporin A (CS & CsA) resistant pediatric idiopathic uveitis (PIU) patients from sensitive counterparts. Serum samples were collected from 32 CS & CsA-sensitive PIU patients and 24 CS & CsA-resistant PIU patients, respectively. UHPLC-OE-MS was employed for comprehensive metabolic profiling of the serum samples. Bioinformatic analyses were performed to identify differentially expressed metabolites (DEMs) between the two patient groups. A machine learning-based classification model was constructed using the identified DEMs as predictive features. For validation purposes, an independent internal cohort of 16 CS & CsA-sensitive and 10 CS & CsA-resistant patients was recruited to evaluate the model's stability. Compared with the CS & CsA-sensitive PIU patients, serum samples from CS & CsA-resistant PIU patients displayed significant metabolic reprogramming. Among the identified differential metabolites, lipids were the most prominently dysregulated class, accounting for 72.47% of all differential metabolites. A machine learning based multivariate feature selection approach including NNET, LASSO, and XGBoost identified 4 candidate metabolite biomarkers. ROC analysis showed that three of these biomarkers (MG 15:0, PI-Cer 28:0;3O, and SPB 20:0;2O) exhibited AUC values of 0.934, 0.953, and 0.904, respectively, and were all upregulated in CS & CsA resistant patients. In contrast, N-acetylaspartic acid showed an AUC of 0.934 and was downregulated in CS & CsA resistant patients. The combined classification model incorporating these 4 metabolites achieved an AUC of 1.0. Validation in an independent internal cohort confirmed the model's excellent performance, with AUC values of 0.971 for NNET, 0.971 for LASSO, and 0.957 for XGBoost. We have established a classification model capable of effectively discriminating CS & CsA-resistant from -sensitive PIU patients. The machine learning model leveraging metabolic biomarkers demonstrates exceptional classification accuracy and generalizability, offering potential for clinical subtype classification.","42435878":"ID: 42435878\nTitle: Muribaculaceae regulate β-muricholic acid to target S1PR2 signaling and reduce neurological injury in intracerebral hemorrhage.\nAbstract: Intestinal flora imbalance after intracerebral hemorrhage (ICH) aggravates neuroinflammation and secondary brain injury through the gut-brain axis, although the specific mechanism remains unclear. This study focuses on the regulatory effects of Muribaculaceae and β-muricholic acid (β-MA, a primary bile acid) on neurological injury after ICH, aiming to reveal the molecular mechanism by which it improves the prognosis of ICH through the sphingosine-1-phosphate receptor 2 (S1PR2). A mouse ICH model was constructed by collagenase induction to evaluate the changes in gut microbiota diversity and metabolites. After intervention with Muribaculum intestinale (MI), neurological function was assessed by behavioral tests, and pathological changes of brain tissue were analyzed by Hematoxylin-Eosin and Nissl staining. Subsequently, intestinal barrier function, inflammatory factors, and total bile acid (TBA) levels were examined in ICH mice. In addition, cell viability, apoptosis, oxidative stress, inflammatory factors, and β-MA levels were analyzed in the heme-induced SH-SY5Y cell model. Molecular docking and drug affinity responsiveness target stability (DARTS) were used to analyze the interaction between β-MA and S1PR2. Intervention with a S1PR2 agonist (CYM-5520) was used to further verify the mechanism. Altered gut microbiota composition, elevated lipopolysaccharide levels, reduced expression of tight junction proteins, inflammatory activation, and disrupted bile acid metabolism were observed in ICH mice. Supplementation with MI ameliorated neural damage, cerebral edema, and neuronal loss in an intake dose-responsive manner, enhanced intestinal barrier integrity, and increased TBA levels. As a primary bile acid, β-MA directly mitigated hemin-induced oxidative stress and inflammation in neural cells. Mechanistically, β-MA downregulated the expression of S1PR2, but overexpression of S1PR2 counteracted the protective effects of β-MA. Furthermore, the administration of CYM-5520 attenuated the neuroprotective effects conferred by MI in vivo. Muribaculaceae alleviated neurological injury after ICH by upregulating β-MA levels, thereby inhibiting the S1PR2 signaling pathway. This research offers a novel approach to treating ICH by focusing on the gut microbiota-bile acid metabolism-neuroprotection axis.","42435958":"ID: 42435958\nTitle: From gut lumen to extragut tissue: dysbiosis-induced gut bacterial translocation mediates antibiotic resistance gene enrichment in Eisenia fetida under polystyrene microplastic and roxithromycin exposure.\nAbstract: Microplastics' (MPs) capacity to sorb antibiotics in soil ecosystems poses emerging risks, yet their combined toxic effects on soil fauna remain poorly understood. Consequently, we examined the gut toxicity and antibiotic resistance genes (ARGs) of polystyrene MPs (PS-MPs) and the macrolide antibiotic roxithromycin (ROX) in Eisenia fetida. Overall, although co-exposure suppressed gut barrier gene expression (occludin and ZO-1), it did not worsen bacterial translocation (LPS and LBP) relative to single exposures, which is associated with the significant upregulation of antibacterial defense indicators (TLR and CCF), potentially enhancing bacterial clearance. Additionally, PS-MPs mediated the reduction of ROX bioaccumulation by 34.78%, which contributed to the antagonistic interactions observed across multiple indicators, including attenuated deterministic assembly of gut microbiota and ARGs under co-exposure. Beyond enriching resistant Actinobacteria (e.g., Streptomyces and Actinophytocola), ROX also enriched plastisphere-associated pathogenic taxa Escherichia and Enterococcus, as did PS-MPs. These taxa were closely implicated in gut barrier dysfunction and exhibited the strongest correlations with gut ARGs and mobile genetic elements (MGEs) profiles, particularly macrolide-lincosamide-streptogramin B (MLSB) resistance genes (mphA-01, oleC) and MGEs (intI-1(clinic), tnpA-02). Though co-exposure did not increase gut ARGs and MGEs abundance, the enrichment of gut-dominant MLSB resistance genes and MGEs extended to earthworm body tissue, notably driven by PS-MPs, while ROX increased intI-1 (clinic), the strongest contributor to overall variation. PLS-PM revealed that tissue ARGs and MGEs enrichment was associated with gut bacterial translocation driven by dysbiosis-induced activation of LPS-TLR signaling pathways, raising concerns about ARGs dissemination through earthworm-derived traditional medicine and food chains.","42436017":"ID: 42436017\nTitle: Harnessing microbial modulators to mitigate antibiotic-induced gut dysbiosis: from phytochemicals to faecal microbiota transplantation.\nAbstract: Antibiotics remain indispensable for the management of infectious diseases; however, their use inevitably perturbs the gut microbiota. Advances in metagenomics and multiomics approaches have demonstrated that antibiotic exposure profoundly disrupts microbial diversity and community structure, leading to the depletion of key commensals, the expansion of opportunistic pathogens, metabolic dysfunction, and the emergence of antimicrobial resistance. These alterations are increasingly associated with a broad spectrum of dysbiosis-related diseases (DRDs), encompassing metabolic, neuropsychiatric, and immune-mediated disorders. To mitigate or reverse antibiotic-induced microbial imbalances, various microbiota-targeted interventions have emerged as promising alternatives or complementary approaches. These include dietary phytochemicals (such as polyphenols, alkaloids, and organosulfur compounds), probiotics, prebiotics, synbiotics, postbiotics, bacteriophage therapy, and faecal microbiota transplantation (FMT). Evidence from in vitro and animal studies has provided mechanistic insights into how these interventions modulate microbial composition and function; however, clinical evidence varies across intervention type. This review summarizes the composition and functional roles of the gut microbiota, outlines the consequences of antibiotic exposure, and provides an overview of the underlying mechanisms, recent evidence, and potential applications of microbiota-targeted interventions in preserving intestinal homeostasis. This review aims to provide a theoretical basis and reference framework for the development of safer and more effective alternatives or adjuncts to antibiotic therapy.","42436035":"ID: 42436035\nTitle: Fermentation of plant- and fungal-protein foods: From processing and food properties to gut microbiome and health.\nAbstract: The shift toward plant- and fungal proteins is driven by environmental and public-health concerns, but wider adoption is constrained by poor sensory quality, limited techno-functionality, and variable nutritional performance. Fermentation has re-emerged as a versatile processing approach because it can improve flavor and texture while remaining compatible with clean-label food design. Yet the effects of fermentation designed for alternative proteins on host physiology remain largely unexplored. This chapter examines how fermentation modifies plant- and fungal-protein foods at multiple levels and how these changes may translate into health-relevant outcomes. After outlining the major chemical and physical transformations induced by fermentation, the chapter moves beyond the traditional focus on nutrients and bioactive metabolites to consider how fermentation-driven changes in flavor and food structure influence gastrointestinal signaling and digestion. Particular attention is given to how in situ production of exopolysaccharides (EPS) during fermentation reshapes matrix organization and governs the delivery of food components along the gastrointestinal tract, where they can be utilized by the host or serve as substrates for gut microbes in complex trophic chains. Accordingly, the gut microbiome provides a key interface for these processes by integrating both chemical and physical cues from foods after ingestion, while also mediating how these cues translate into physiological responses, thereby serving as a composite readout of food properties and host physiology. By highlighting what is known and where evidence is emerging, this chapter aims to support the future rational design of fermented plant- and fungal-protein foods for both product performance and health.","42436039":"ID: 42436039\nTitle: Fermentation of plant-based foods: Microbial consortia and their impacts on composition, sensory quality, and health benefits of food products.\nAbstract: Fermented plant-based foods have obtained growing interests for their improved nutrition profile, enhanced flavor and taste, as well as their health-promoting properties. Fermentation using lactic acid bacteria (LAB) and yeasts can eliminate antinutritional components and off-flavor compounds present in plant matrices while also generating beneficial metabolites. The interaction between fermentative microbes and plant substrates is dependent on plant matrices, microbial strains, and processing conditions. Accumulating evidence indicates that fermentation modifies the generation, degradation, and bioavailability of food bioactive compounds such as bioactive peptides, vitamins, volatiles, phenolics, phytic acid and phytates, saponins, and raffinose-family oligosaccharides. This chapter reviews and critically examines research data on microbial transformations of bioactive compounds in fermented plant matrices and pinpoints key factors contributing to inconsistent findings. It also identifies key research directions for understanding and applying fermentation-driven changes to improve the nutritional and functional quality of plant-based fermented foods.","42436149":"ID: 42436149\nTitle: ENO2 sustains cancer stemness and metastatic competence through a phosphoenolpyruvate-dependent metabolic axis in triple-negative breast cancer.\nAbstract: Enolase 2 (ENO2) is a neuron-specific glycolytic enzyme whose expression is elevated in aggressive breast cancers, yet its enzymatic and biological contributions to triple-negative breast cancer (TNBC) progression remain incompletely defined. Here, we demonstrate that ENO2 sustains cancer stem cell (CSC) properties and metastatic competence through a phosphoenolpyruvate (PEP)-dependent metabolic axis. Elevated ENO2 expression correlated with advanced tumor grade and poor clinical outcomes in TNBC cohorts, underscoring its clinical relevance. Genetic depletion of ENO2 impaired aerobic glycolysis and oxidative phosphorylation, reduced migration, invasion, and CSC frequency, and suppressed tumor growth and pulmonary metastasis in orthotopic models. Mechanistically, exogenous PEP or pyruvate restored CSC-associated traits and invasiveness in ENO2-deficient cells, supporting the functional involvement of ENO2-derived metabolites in CSC maintenance. Reconstitution with wild-type ENO2, but not a catalytically impaired mutant, restored CSC properties, invasiveness, and metastatic colonization, establishing that ENO2 catalytic activity is required for these malignant traits. Further analysis revealed that PKM2 perturbation preferentially attenuated PEP-mediated rescue while largely sparing pyruvate-mediated rescue, supporting a functional PEP-PKM2-pyruvate axis in CSC regulation. Consistently, PKM2 depletion partially blunted ENO2-mediated rescue; however, residual rescue despite PKM2 perturbation suggested additional PKM2-independent PEP-responsive mechanisms. Importantly, pharmacological inhibition of enolase with POMHEX phenocopied genetic ENO2 loss and suppressed CSC maintenance in vitro and tumor growth in vivo. Taken together, these findings identify the ENO2-driven PEP-dependent metabolic axis as a mechanistic link between metabolic reprogramming, cancer stemness, and metastasis, revealing a therapeutically actionable metabolic vulnerability in TNBC.","42436161":"ID: 42436161\nTitle: Dietary glucoraphenin ameliorates obesity and steatotic liver disease associated with gut dysbiosis induced by a Western diet in mice.\nAbstract: Western-style diets promote obesity, gut dysbiosis, and metabolic dysfunction-associated steatotic liver disease (MASLD). In this study, glucoraphenin (GRE), the major glucosinolate in radish (Raphanus sativus L.) greens and sprouts, was evaluated for its effects on Western diet (WD)-induced metabolic derangements and gut dysfunction in mice. Intaking of 1 mg/kg body weight of GRE with WD for 8 weeks caused significant reductions in adipogenesis indicators such as body weight gains, adipocyte hypertrophy, and serum leptin level. This result was further proved by significant changes in lipogenesis and lipolysis-related protein expressions in adipocyte. Administration of GRE also suppressed development of MASLD, which was observed through reductions in serum ALT and AST and suppressions the expression of FAS, SREBP1, mTOR, SCD1, ACC, and ChREBP in liver tissues. GRE administration effectively prevented the decrease in the gut microbial richness and diversity caused by WD and recovered serum branched-chain amino acids and microbiota-derived purine metabolites (inosine and hypoxanthine). These findings indicate that GRE mitigates WD-induced obesity and MASLD via coordinated regulation of lipid metabolism and the gut-liver axis.","42436181":"ID: 42436181\nTitle: Protein-rich food matrices from alternative and conventional sources differentially shape gut microbiota, metabolic function, and muscle protein synthesis.\nAbstract: The functional consequences of consuming conventional and alternative protein rich food matrices remain poorly understood. This study characterized diverse protein rich food matrices and investigated their effect on gut microbiota, muscle protein synthesis, and host metabolic function in rats. Arthropods and lentils contained chitin, resistant starch, polyphenols, and antioxidant activity, whereas egg and picanha were enriched in cholesterol and precursors of trimethylamine N-oxide (TMAO). Lentils and crickets consumption resulted in the lowest fat mass gain, glucose area under the curve and serum lipopolysaccharide (LPS) concentration and lentils the highest fecal butyrate. Gut microbiota alpha diversity was similar among rats fed casein, cricket, acocil, and beef diets, whereas diets containing higher amounts and different types of fat, including egg, picanha, and chinicuil, reduced alpha diversity. Cricket consumption increased the abundance of Faecalibacterium, whereas lentil consumption promoted Bifidobacterium. Rats fed picanha or egg exhibited the highest serum LPS concentrations, while acocil and beef induced the greatest stimulation of muscle protein synthesis followed by cricket, egg, and lentil diets. Biological effects of dietary protein depend on the entire food matrix rather than content alone and cricket and lentil matrices emerge as sustainable protein sources.","42436184":"ID: 42436184\nTitle: Advances in synbiotics and synbiotic functional foods in type 2 diabetes mellitus treatment.\nAbstract: The increasing incidence of type 2 diabetes mellitus (T2DM) globally necessitates alternative therapeutic strategies. Evidence suggests that intestinal microbiota significantly influences T2DM development, leading to the proposal of probiotics as potential treatments. However, challenges such as strain selectivity and low survival rates limit probiotics' effectiveness. Combining probiotics with prebiotics, known as synbiotics, offers a promising approach for managing T2DM. The development of synbiotic-based functional foods also provides effective interventions for T2DM. This article synthesizes the recent advancements of synbiotics and synbiotic functional foods in managing T2DM, covering 40 studies, of which 29 studies employed synbiotics, and 11 studies employed synbiotic functional foods. In the 21 human studies, 17 focused on T2DM treatment and another 4 on the prevention of prediabetes from developing to T2DM. As for probiotics, 20 studies used single-strain probiotics, while others employed multiple strains, with 5 focusing on the synbiotics combined with hypoglycemic substances. Overall, synbiotics and synbiotic functional foods offer therapeutic benefits by reducing inflammation and oxidative stress, regulating gut microbiota, enhancing short-chain fatty acids, and improving intestinal barrier function. Further research is crucial to determine optimal formulations, dosages, and long-term safety, along with developing new synbiotic functional foods for effective diabetes interventions.","42436215":"ID: 42436215\nTitle: Prebiotic and postbiotic synergy alleviates age-related dysbiosis and inflammation in mice.\nAbstract: Advances in medicine and veterinary medicine extend the lifespan of humans and companion animals. Interest in nutritional strategies to support healthy aging consequently increases. In this study, the effect of 11% scFOS+ supplementation (a blend of short-chain fructo-oligosaccharides and yeast-derived postbiotics) in 18-month-old mice was evaluated, compared with aged or adult mice of 9 weeks old on a control diet. Bodyweight and food intake were monitored throughout the 56-day study. Faecal samples were collected on days 0, 28, and 56, and caecal samples at the end of the study (day 56), for microbiota analysis. Immune markers, including cytokine production in tissues and blood and toll-like receptor (TLR) expression, were analysed at day 56. The results showed that scFOS+ supplementation reduced the abundance of potentially pathogenic bacterial species and enhanced the growth of beneficial genera like Allobaculum and Bifidobacterium, aligning the microbiota profile of aged mice more closely with that of adult mice. The pro- and anti-inflammatory balance was maintained in supplemented old mice, and their TLR expression patterns resembled those observed in adults. In conclusion, combining prebiotics and postbiotics modulates immune responses in aged mice, restoring adult-like levels through gut microbiota changes and suggesting potential for promoting healthy aging in companion animals.","42436254":"ID: 42436254\nTitle: Functional characterization of fungal endophytes with antagonistic and plant growth-promoting activities in maize.\nAbstract: Fungal endophytes play a crucial role in plant-microbe interactions by asymptomatically colonizing host tissues, enhancing plant growth, and providing defense. In the present study, three distinct endophytic fungi, namely Fusarium oxysporum CJR-1 (GenBank Accession No. PZ477045), Penicillium sp. CJR-2 (GenBank Accession No. PZ477429) and Aspergillus cf. terreus CJR-4 (GenBank Accession No. PZ477430) were isolated from Crotalaria juncea L. plants and evaluated for antagonistic activity against phytopathogenic fungi and growth promotion in maize. Among the isolates, CJR-4 showed potent antagonistic activity against both tested phytopathogens, inhibiting the mycelial growth of Fusarium oxysporum (ITCC Accession No. 8111) and Alternaria alternata (ITCC Accession No. 1434) by 72.41 ± 5.02% and 68.31 ± 1.53%. On the other hand, isolate CJR-1 showed the highest mycelial inhibition of 74.60 ± 2.06% against A. alternata. Ethyl acetate crude metabolites of CJR-4 exhibited potent antifungal activity, with the highest zone of inhibition observed against A. alternata (21.66 ± 1.52 mm), followed by F. oxysporum (15.33 ± 1.15 mm) at 150 µL of tested concentration. GC-MS analysis of the ethyl acetate extract of CJR-4 revealed numerous bioactive metabolites, including diphenyl sulphone and 2-nonen-1-ol, which may contribute to its antifungal activity. In addition, 1-methylene-1H-indene and ethanone, 2-(formyloxy)-1-phenyl-, may be associated with antioxidant activity, as evidenced by potent DPPH (80.09 ± 0.11%) and ABTS (92.66 ± 0.17%) scavenging activities. Evaluation of PGP traits showed that CJR-1 produced the highest levels of indole-3-acetic acid (IAA) as 305.69 ± 0.41 µg mL⁻1 and ammonia 85.44 ± 0.63 µg mL⁻1, while CJR-2 exhibited the highest phosphate solubilization index (PSI) of 3.09 ± 0.09. Pot experiments conducted under natural light conditions for 28 days demonstrated significantly enhanced plant growth parameters, biomass accumulation, and photosynthetic pigment levels in maize plants inoculated with the CJR-4 isolate. Overall, the findings highlight that endophytic fungi exhibit multifunctional roles and show promise as microbial inoculants for sustainable crop improvement, with CJR-4 emerging as the promising candidate for further development. To the best of our knowledge, this study is among the first to report the isolation and functional characterization of endophytic fungi from Crotalaria juncea L. plant.","42436400":"ID: 42436400\nTitle: Association of TNNI3 and MYBPC3 variants with clinical phenotype and metabolic disorders in patients with hypertrophic cardiomyopathy.\nAbstract: Hypertrophic cardiomyopathy is an inherited cardiovascular disease with heterogeneous presentation. However, the metabolic changes resulting from mutations and their relationship to the phenotype remain unclear. To investigate the association between TNNI3 and MYBPC3 variants and both clinical phenotype and metabolic disorders in HCM patients. 34 newly diagnosed HCM patients, 51 healthy individuals, and 23 unaffected family members were included. Clinical information and plasma samples were collected and analyzed. Whole-exome and Sanger sequencing were used for variant identification. Non-targeted metabolomics was performed using ultra-high-performance liquid chromatography-high-resolution mass spectrometry. TNNI3 and MYBPC3 variants were identified in familial HCM cases, which exhibited earlier onset and increased interventricular septum thickness. Metabolomics revealed lower L-valine and higher free fatty acid levels in HCM patients. Patients with TNNI3 variants showed dysregulation of lyso-phosphatidylcholines and lyso-phosphatidylethanolamines, along with disturbances in glutamic acid-related pathways. MYBPC3 variants were linked to dysregulation in energy metabolism. Correlation analysis highlighted associations between specific lipid metabolites and cardiac structure and function. Significant metabolic alterations, particularly in amino acid and lipid metabolism, are prevalent in HCM. These findings enhance our understanding of HCM pathogenesis and suggest potential biomarkers and therapeutic targets for this genetic heart disease.","42436507":"ID: 42436507\nTitle: Spectroscopic and elemental evaluation of Pb(II), Cu(II), and Hg(II) binding by salvia officinalis L. leaf extract.\nAbstract: Heavy metal contamination remains a major environmental concern because toxic ions such as Pb(II), Cu(II), and Hg(II) persist in ecosystems and pose serious risks to the environment and human health. Plant-derived extracts rich in phenolic acids, flavonoids, and other heteroatom-containing phytochemicals offer a promising natural matrix for metal binding through hydroxyl, carbonyl, and C-O-containing functional groups. This study presents a comparative matrix-level evaluation of interactions of Pb(II), Cu(II), and Hg(II) with Salvia officinalis L. leaf extract by integrating UV-Vis spectroscopic stoichiometry, apparent binding analysis, pH- and temperature-dependent spectral responses, EDTA-assisted reversibility, FTIR functional group assignments, and ICP-OES-based elemental validation. UV-Vis data were evaluated using Job's plot analysis, while apparent binding parameters were estimated using the extended Benesi-Hildebrand and Scatchard models, based on the observed stoichiometric behaviour. Pb(II) and Hg(II) exhibited apparent M₂L-type interaction patterns, whereas Cu(II) showed a 1:1 binding mode. Among the tested ions, Hg(II) produced the strongest spectroscopic binding response, followed by Pb(II) and Cu(II). The metal-extract interactions were strongly affected by pH and temperature, with more pronounced spectral responses under mildly alkaline conditions and at temperatures above 45 °C. EDTA addition indicated that the binding process was at least partially reversible, suggesting the potential regeneration of the extract-based metal-binding system. ICP-OES analysis supported the incorporation of metals into the extract-derived complexes, whereas changes in FTIR spectra indicated the involvement of hydroxyl, carbonyl, and C-O groups in metal coordination. Overall, the findings demonstrate the metal-dependent binding behavior of S. officinalis leaf extract and provide a useful spectroscopic and elemental basis for further studies on plant-derived metal-binding systems.","42436519":"ID: 42436519\nTitle: Integrating untargeted metabolomics and machine learning to reveal an aberration of sphingolipid metabolism in cardiometabolic HFpEF.\nAbstract: Cardiometabolic heart failure with preserved ejection fraction (HFpEF) is a high-risk phenotype primarily driven by metabolic syndrome, with a significantly increased incidence and risk of adverse outcomes. A fundamental reason for this is the lack of early clinical diagnosis. As a tool capable of accurately capturing pathophysiological states, metabolomics provides a critical entry point for addressing this issue; however, studies focusing on the metabolic characteristics of this population remain limited. This study integrated a clinical cohort and untargeted metabolomics to compare serum metabolic profiles between patients with cardiometabolic HFpEF and those with metabolic syndrome (MetS). Baseline characteristics were balanced using propensity score matching (PSM). Differential metabolites were identified by untargeted metabolomics, followed by KEGG pathway enrichment analysis. Machine-learning approaches were further applied to screen candidate metabolites with potential diagnostic efficacy, and weighted gene co-expression network analysis (WGCNA) together with SHapley Additive exPlanations (SHAP) were used to evaluate phenotype association and feature contribution. In an independent clinical cohort, total sphingomyelin (SM) levels were assessed by ELISA as an external evaluation strategy based on clinical applicability. Differential metabolites between the two groups were mainly enriched in sphingolipid metabolism and glycerophospholipid metabolism pathways. Through multi-method screening, C24:1 Sphingomyelin was identified as a candidate metabolite with potential diagnostic efficacy. The co-expression module containing C24:1 Sphingomyelin was significantly correlated with NT-proBNP, a key biomarker of heart failure, and SHAP analysis indicated that C24:1 Sphingomyelin contributed substantially to the classification model. In the external cohort, total SM levels were associated with disease status, suggesting the potential clinical association of sphingolipid-related signals. This study preliminarily characterized the metabolic features distinguishing cardiometabolic HFpEF from MetS alone, suggesting that sphingolipid dysregulation is associated with the development and progression of this phenotype. Among the identified metabolites, C24:1 Sphingomyelin was identified as a candidate metabolite with potential diagnostic performance, and SM showed potential clinical applicability. These findings provide new clues for biomarker discovery and preliminary clinical translational exploration in cardiometabolic HFpEF.","42436575":"ID: 42436575\nTitle: Host genetic architecture and gut microbiota cooperatively regulate early growth in goats.\nAbstract: Early postnatal growth is a critical determinant of meat production efficiency and long-term genetic improvement in goats; however, the molecular mechanisms underlying individual variation in growth performance remain poorly understood. In this study, a total of 123 Hechuan white goats were included. First, a genome-wide association study (GWAS) for average daily gain (ADG) was performed using all 123 individuals. Subsequently, based on the coefficient of variation of ADG (CV = 65.6%), an extreme phenotype sampling (EPS) strategy was applied to select 39 individuals with extreme growth phenotypes for subsequent metabolomic, microbiome, and integrated mGWAS analyses.The results showed that ADG approximately followed a normal distribution across the 123 goats. GWAS identified 22 loci significantly associated with ADG, mapping to genes including DLK1, NCAPG2, LCORL, CNTNAP2, and SLC8A1, which are involved in pathways related to skeletal muscle development, cell cycle regulation, ion transport, and immune function. Metabolomic profiling detected 1,589 putative metabolites, revealing differential enrichment of lipid, amino acid, and bile acid metabolic pathways between fast- and slow-growing goats. Gut microbiome analysis demonstrated that Christensenellaceae_R-7_group and Monoglobus were significantly enriched in fast-growing individuals, whereas Desulfovibrio was more abundant in slow-growing goats.Integrated mGWAS analysis further revealed extensive effects of host genetic variation on gut microbiota and fecal metabolites. Specifically, 11 bacterial genera were significantly associated with host genomic variants, among which Desulfovibrio exhibited the highest number of associated loci. Integration of multiple variant types consistently linked Desulfovibrio, Eubacterium_hallii_group, and Candidatus_Saccharimonas with genes such as ARHGAP24 and IGF2BP2. In addition, 14 metabolites were significantly associated with host genetic variants, with Lysopc(14:1(9Z)/0:0) and glycocholic acid showing the strongest associations. Notably, the peak signal for Lysopc was located within HMGA2.Collectively, these findings define a coordinated host genome-gut microbiota-metabolite network underlying early growth variation in goats and provide a mechanistic foundation for precision breeding and targeted nutritional strategies in goat production systems.","42436592":"ID: 42436592\nTitle: Impact of United States marine corps recruit training on the stress response and menstrual function in female marine recruits.\nAbstract: This study investigated the physiological stress response and menstrual cycle (MC) function in Marine recruits during United States Marine Corps Recruit Training at the Marine Corps Recruit Depot in San Diego, CA. Female recruits (n = 120) completed pre- and post-RT MC surveys. Saliva samples were collected at 6 timepoints (pre-RT, weeks 1, 4, 7, 10, post-RT) and analyzed for stress biomarkers. Urine samples were collected pre-RT, 5 days per week during RT, and post-RT to assess sex hormone metabolites. Linear mixed-effects models assessed time effects (p < 0.05). Pre-RT sAA levels were higher than weeks 4 (p < 0.001), 7 (p < 0.001), and 10 (p = 0.003). Week 1 sAA levels were greater than week 7 (p = 0.049) and post-RT sAA levels were greater than week 4 (p = 0.011), 7 (p < 0.001), and 10 (p = 0.046). Cortisol at weeks 1 (p = 0.004) and 4 (p < 0.001) was greater than week 10. Before RT, 85% reported regular MCs; during RT, 53% reported irregularity. Urine measures indicated 92% experienced MC disruption, 87.5% within the first cycle. Recruits experienced heightened stress early in RT but adapted as training progressed. Most recruits exhibited MC irregularities, with disruption occurring in the first cycle, indicating heightened hypothalamic-pituitary-ovarian axis sensitivity to military training stress.","42436634":"ID: 42436634\nTitle: From raw to steamed Panax notoginseng: A systematic review of saponin transformations and their functional consequences.\nAbstract: Notoginseng Radix et Rhizoma (NRR), derived from Panax notoginseng, serves as both a functional food and a key medicinal material in traditional Chinese medicine. Its bioactivity is largely attributed to saponins, which undergo significant chemical transformations during processing (e.g., steaming), altering its pharmacological profile. This review aims to systematically consolidate experimentally verified metabolites from authenticated NRR, elucidate the chemical transformations induced by processing and clarify the resulting shift in pharmacological effects, thereby providing a scientific basis for its targeted application. A comprehensive literature search was conducted using CNKI, Wanfang Data, National Science and Technology Library, the Pharmacopoeia of the People's Republic of China, PubMed and Web of Science. Keywords included Panax notoginseng (Burk.) F. H. Chen; Pharmacological activities; Phytochemisity; Saponin transformation; Traditional processing; Traditional Chinese medicine. Data were also sourced from classic texts, dissertations and unpublished materials. Processing, particularly steaming, converts high-polarity saponins into less polar ones via deglycosylation, dehydration and hydroxylation. This chemical shift underlies a functional transition: raw NRR primarily promotes blood activation and stasis dispersion, while processed NRR exhibits enhanced blood-nourishing, antioxidant, anti-inflammatory and immunomodulatory activities. The integration of ethnopharmacological knowledge with modern scientific perspectives clarifies the metabolite pathways and mechanistic basis for processing-induced changes in NRR. This review provides a reliable foundation for the precise use and further development of NRR in functional foods, nutraceuticals and evidence-based therapy.","42436725":"ID: 42436725\nTitle: In vivo targeted MRS detection of 2-hydroxyglutarate molecules in IDH-mutant gliomas via spin regulation.\nAbstract: 2-hydroxyglutarate (2-HG) is a key metabolic biomarker for identifying IDH-mutant gliomas. Non-invasive and accurate detection of 2-HG is of great significance for the early diagnosis of diseases and dynamic monitoring of therapeutic efficacy. However, conventional magnetic resonance spectroscopy (MRS) faces challenges in detecting 2-HG in vivo, mainly due to the overlap of its resonance peaks with those of metabolites such as glutamate (Glu) and N-acetylaspartate (NAA). Although the long echo time (TE) filtering method can separate signals to a certain extent, it is often accompanied by peak distortion and signal attenuation, which limits its clinical application. To address this problem, this study proposes a 2-HG-targeted detection sequence based on optimal control pulses. By applying optimal control pulses to regulate the state evolution of a 14-spin system composed of 2-HG, Glu, and NAA molecules, the study achieves selective retention of 2-HG signals and suppression of other molecular signals. In experimental verification conducted on phantoms and IDH-mutant glioma animal models, the targeted sequence exhibited excellent signal resolution performance: it efficiently retained 2-HG signals and achieved approximately 95% and 98% suppression of Glu and NAA signals, respectively. To further verify the quantitative reliability of the targeted sequence, the 2-HG concentrations measured by this sequence were compared with those obtained by liquid chromatography-tandem mass spectrometry (LC-MS/MS). A high linear correlation was found between the two sets of results, which fully confirms the accuracy of non-invasive quantitative detection of 2-HG using the targeted sequence.","42436753":"ID: 42436753\nTitle: Structural evolution and prebiotic-like potential of insoluble dietary fiber-polyphenol complexes from Rosa roxburghii Tratt during in vitro digestion and colonic fermentation.\nAbstract: Rosa roxburghi Tratt. (RRT) pomace is rich in insoluble dietary fiber (IDF) and polyphenols, but free polyphenols are susceptible to premature loss during digestion. This study constructed an IDF-polyphenol complex (IDF-PP) from RRT pomace via non-covalent adsorption and evaluated its gastrointestinal fate and in vitro colonic fermentation behavior. IDF-PP reduced premature phenolic loss during simulated upper gastrointestinal digestion and enabled a more gradual release during fermentation. Structural analyses showed fermentation-induced remodeling, generating a porous residual matrix while retaining part of the polysaccharide framework. Compared with free polyphenols and IDF, IDF-PP increased short-chain fatty acid production, especially butyrate, and was associated with higher relative abundance of Prevotella-centered Bacteroidetes taxa and Faecalibacterium, together with lower relative abundance of Proteobacteria. Fermentation products also showed enhanced antioxidant and α-glucosidase inhibitory activities. These findings suggest that RRT pomace-derived IDF-PP is a promising fermentation-responsive functional ingredient with potential to modulate gut microbial fermentation."},"globalTags":{"in vitro
