Growing evidence shows that metabolites generated along the gut-brain axis regulate neuroinflammation.

To address this question, we investigated a monogenic form of epilepsy (pyridoxine-dependent epilepsy) caused by aldehyde dehydrogenase 7 family member A1 (ALDH7A1) mutations. ALDH7A1 global knockout mice exhibited both seizure-associated and maladaptive affective behavioral phenotypes. However, seizure phenotypes were caused by ALDH7A1 deletion in hepatocytes whereas maladaptive affective behaviors were caused by ALDH7A1 deletion in astrocytes. Deletion in astrocytes disrupted astrocyte redox homeostasis, impairing regulation of extracellular ion concentrations and reducing neuronal activity in the prelimbic cortex. Sulforaphane, which activates the NRF2 antioxidant pathway, restored prelimbic neuronal activity and rescued maladaptive affective behaviors in ALDH7A1 knockout mice but did not prevent seizures. These studies implicate astrocyte redox homeostasis and prelimbic hypoactivity in maladaptive affective behavioral phenotypes in a congenital form of epilepsy, which are mechanistically and therapeutically dissociable from seizure pathophysiology."

Previously, the 1st known ER-phagy receptor gene RETREG1 (RETR1)/FAM134B gene was reported to restrict Ebola virus (EBOV) replication in vivo by inhibiting the viral glycoprotein (GP) and viral protein 40 kDa (VP40) expression, but this mechanism remains unknown. Here, we identify the truncated RETR1/FAM134B isoform 2 (RETR1-2), but not its full-length protein RETR1, as an ER-phagy receptor that targets EBOV-GP for degradation. RETR1-2 broadly triggers GP degradation across ebolavirus species but not Marburg virus and inhibits EBOV replication. Mechanistically, RETR1-2 recognizes EBOV-GP via its luminal domain, undergoes GP-induced oligomerization, and directs GP-containing ER membranes to lysosomes through canonical macro-autophagy. Using unbiased mass spectrometry, we identified TOLLIP as the key cytoplasm adaptor for RETR1-2, which also requires cooperation with the ER chaperone calnexin for EBOV-GP degradation. Notably, the PI3P-binding C2 domain of TOLLIP mediates its interaction with RETR1-2, and the EBOV-GP degradation occurs independently of ubiquitination, revealing an unexpected role for TOLLIP in ER-phagy. Furthermore, EBOV-VP40 antagonizes this pathway by selectively targeting RETR1-2 for macroautophagic degradation independently of TOLLIP, thereby restoring GP expression and viral infectivity. Nevertheless, RETR1-2 reciprocally degrades VP40 via a similar mechanism. Together, these findings define a calnexin-TOLLIP-RETR1-2 axis that links ER quality control to ER-phagy-mediated antiviral restriction and uncover a reciprocal host-virus arms race centered on selective macro-autophagy."

Here, we examined the effects of two haloacetamides, 2,2-dichloroacetamide (DCAcAm) and 2,2-dibromoacetamide (DBAcAm), on mouse oocyte maturation and identified the underlying mechanisms of toxicity. Both compounds markedly impaired meiotic spindle assembly and compromised the function of multiple organelles, including mitochondria, the endoplasmic reticulum, and the Golgi apparatus, primarily through autophagy dysregulation at specific exposure concentrations, as evidenced by the observation that more than half of the oocytes failed to progress beyond the MII stage. Spermidine supplementation effectively restored autophagic activity and rescued the associated cellular defects, thereby improving both nuclear and cytoplasmic maturation in oocytes. Collectively, these findings demonstrate that spermidine alleviates toxicant-induced deterioration of oocyte quality by regulating autophagy and highlight its potential therapeutic value for reproductive protection and clinical application."

However, the pathogenesis of CI\u2011AKI remains to be fully elucidated. Sulforaphane (SFN), a NRF2 agonist, exhibits anti\u2011inflammatory, antioxidant and anti\u2011apoptotic effects, thus SFN exerts protective effects in kidney injury diseases. However, the possible role and underlying mechanisms of SFN in CI\u2011AKI remain ambiguous. An in vivo model of CI\u2011AKI was constructed using C57BL/6 mice that were administered a single intraperitoneal cisplatin injection (20 mg/kg) and conditionally treated with SFN (10 mg/kg). Serum creatinine (Scr) and blood urea nitrogen (BUN) levels were detected by biochemical analysis. Western blotting was performed to assess the expression of renal injury markers, as well as the apoptosis\u2011related proteins cleaved caspase\u20113, caspase\u20113, Bax and Bcl\u20112. Furthermore, hematoxylin and eosin and periodic acid\u2011Schiff staining were employed to detect renal tissue lesions in mice, and TUNEL staining was used to evaluate the apoptosis of renal tissues in each group in vivo. Immunohistochemistry was used to assess the expression of inflammatory marker F4/80 in mouse renal tissues, and ELISA was used to detect the expressions of the inflammatory markers IL)\u20111\u03b2, IL\u20116 and tumor necrosis factor\u2011\u03b1 (TNF\u2011\u03b1) in the serum of mice in each group. DCFH\u2011DA) analysis was used to detect reactive oxygen species (ROS) levels and biochemical analysis was used to evaluate the expression levels of malondialdehyde, superoxide dismutase and glutathione. Finally, western blotting and immunohistochemistry were performed to evaluate the expression of NRF2. An in vitro model of CI\u2011AKI was constructed using HK\u20112 cells induced by cisplatin (10 \u00b5g/ml) that were conditionally treated with one or both of SFN (5 \u00b5M) and the NRF2 inhibitor ML385 (1.9 \u00b5M). Reverse transcription\u2011quantitative PCR was performed to evaluate the expression of NRF2. Cell Counting Kit\u20118 assay was performed to assess the viability of HK\u20112 cells in different groups, whereas flow cytometry was used to assess the apoptosis of HK\u20112 cells in different groups. DCFH\u2011DA analysis was performed to evaluate the expression of ROS in different treatment groups. Furthermore, ELISA was used to evaluate the expressions of IL\u20111\u03b2, IL\u20116 and TNF\u2011\u03b1 in each group. SFN notably decreased the serum levels of Scr and BUN and decreased the expression levels of kidney injury molecule\u20111 and neutrophil gelatinase\u2011associated lipocalin in the cisplatin\u2011induced model group. Histopathological examination revealed attenuated renal structural damage and preserved tubular architecture in the SFN intervention group. Furthermore, SFN notably inhibited the apoptosis, inflammation and oxidative stress of renal tissues induced with cisplatin. Additionally, SFN markedly upregulated NRF2. In vitro, the NRF2 inhibitor ML385 partially attenuated the effects of SFN on the viability, apoptosis, inflammation and oxidative stress of HK\u20112 model cells. The present study indicated that SFN exerted its nephroprotective effect through NRF2\u2011mediated anti\u2011inflammatory, antioxidant and anti\u2011apoptotic mechanisms, positioning SFN as a promising therapeutic candidate for clinical management of chemotherapy\u2011associated kidney injury."

Current treatments offer limited efficacy, necessitating the development of innovative multitarget therapeutic strategies. Here, we present N3,N5-bis(2-(5-methoxy-1H-indol-3-yl)ethyl)-2,6-dimethyl-4-(2-nitrophenyl)pyridine-3,5-dicarboxamide (HCM-01), a novel compound developed to target multiple neurodegenerative pathways implicated in AD. In vitro assays included MTT-based cell viability analyses performed in two complementary experimental settings: primary neuronal cultures and astrocyte-based in vitro cell culture models exposed to glutamate. In primary hippocampal neuronal cultures, glutamate exposure induced a statistically significant reduction in cell viability compared with vehicle-treated controls, consistent with glutamate-induced excitotoxicity. Under these conditions, HCM-01 treatment resulted in a statistically significant improvement in neuronal viability, showing a greater protective effect compared with donepezil and memantine. In contrast, in astrocyte-based in vitro cultures, the applied glutamate concentration did not induce overt cytotoxicity, in line with the intrinsic neuroprotective and glutamate-buffering role of astrocytes. Accordingly, astrocytic experiments were designed to assess functional modulation of glutamate-handling mechanisms rather than cell survival. Western blot analysis in C8-D1A astrocytic cells demonstrated increased expression of excitatory amino acid transporter 2 (EAAT2) following HCM-01 treatment compared with control and reference drug-treated groups, suggesting modulation of astrocyte-mediated glutamate homeostasis. In parallel, redox analyses revealed that HCM-01 improved oxidative/antioxidative balance, as evidenced by increased total antioxidant capacity (TAC) and reduced total oxidant status (TOS), supporting an indirect antioxidant contribution to its functional effects. In vivo behavioral assessment of HCM-01 in a streptozotocin (STZ)-induced Alzheimer's model in female Sprague-Dawley rats demonstrated that administration of HCM-01 at doses of 50 mg/kg orally (oral, P.O. and intraperitoneal, I.P.) and 100 mg/kg (P.O.), significantly improved cognitive and memory functions in the passive avoidance (PA), Morris water maze (MWM), and locomotor activity tests. Moreover, histopathological and immunohistochemical analyses of different hippocampal regions revealed reduced neuronal damage, attenuation of tau pathology, antiamyloidogenic effect, and restoration of cholinergic function. Complementary in silico studies, including molecular docking, molecular dynamics simulations (MDS), and free energy calculations, suggested potential interactions of HCM-01 with the allosteric site of EAAT2. Taken together, these findings suggest that HCM-01 exerts neuroprotective effects against glutamate-induced excitotoxicity in primary hippocampal neurons while additionally modulating glutamatergic homeostasis and redox balance through functional mechanisms in astrocyte-based models, supporting its relevance as a multitarget preclinical candidate for early stage AD mechanisms."

This narrative review maps the adverse outcome pathways (AOPs) through which ethanol impairs synaptic function, primarily via interconnected cascades: TLR4/NF-\u03baB-mediated neuroinflammation (triggering microglial activation and pro-inflammatory cytokines TNF-\u03b1, IL-1\u03b2), CYP2E1-driven oxidative stress (generating ROS/RNS, 4-HNE, causing protein carbonylation and mitochondrial dysfunction), and glutamate excitotoxicity (mediated by GluN2B-NMDAR subunit shifts, Ca\u00b2\u207a overload, and astrocytic EAAT2/GLT-1 downregulation). These pathways converge to suppress BDNF/TrkB signaling (via miR-206 and impaired proBDNF cleavage), leading to deficits in synaptic protein synthesis (e.g., Arc) and trafficking (e.g., GluA1 endocytosis via STEP, impaired forward trafficking). Critically, these insults potentiate neuronal apoptosis through intrinsic (ROS/mitochondrial permeabilization, caspase-9/-3) and extrinsic (TNF-\u03b1/TNF-R1, caspase-8) pathways, executing irreversible synaptic loss via caspase-3 cleavage of PSD-95, spectrin, and cytoskeletal collapse. The structural consequences-dendritic simplification, reduced mature spine density, and PSD-95 nano-domain disorganization-manifest functionally as attenuated LTP, potentiated mGluR-LTD, and impaired STDP. This synaptic decay directly underpins cognitive impairments in pattern separation, contextual memory, and cognitive flexibility. Neuroinflammation (TLR4/NF-\u03baB) acts as a central amplifier, linking oxidative damage, excitotoxicity, and BDNF collapse to apoptotic synaptic deletion. Future research must address dose-dependency, subfield vulnerability, epigenetic regulation, and therapeutic strategies targeting TLR4, TrkB, mitochondrial antioxidants, and anti-apoptotic pathways."

Here, we investigated whether the polyamine biosynthetic enzyme S-adenosylmethionine decarboxylase 1 (AMD1) regulates tubular senescence and repair outcomes after AKI and elucidated the underlying mechanism. AMD1 dynamics were examined in an ischemia-reperfusion injury model using male C57BL/6J mice by immunofluorescence. AAV-mediated Ksp promoter-driven tubule-specific Amd1 conditional knockdown male mice (Amd1 cKD) were used to assess renal injury, cell-cycle status, senescence, and remodeling, and exogenous spermidine was administered for rescue. DNA damage signaling and p53/p21 activation were evaluated by immunostaining, Western blotting, and EdU incorporation assays. AMD1 was predominantly expressed in the tubular epithelium, with prominent dynamic induction in proximal tubules early after IRI, but declined to baseline levels during the late phase, representing a relative metabolic insufficiency that correlated inversely with fibrosis. Compared with wild-type controls, Amd1 cKD mice exhibited aggravated tubular injury, an over two-fold increase in SA-\u03b2-gal-positive areas, elevated p21, and reduced Ki67+ proliferation. Conversely, spermidine supplementation improved renal function, reduced fibrosis by 75.3%, and decreased senescent regions by 74%. Mechanistically, AMD1 deficiency increased \u03b3H2AX-marked DNA damage and activated the p53/p21 checkpoint, whereas spermidine attenuated this response and restored DNA synthesis capacity. Collectively, tubular AMD1 acts as a metabolic checkpoint that preserves polyamine homeostasis to restrain p53/p21-dependent senescence, promote adaptive repair after AKI, and spermidine supplementation represents a potential strategy to mitigate maladaptive AKI-to-CKD progression."

This study explores the interplay of endoplasmic reticulum stress (ERS), autophagy, and apoptosis in Cd-induced hepatotoxicity, focusing on whether ERS-driven autophagy protects against liver injury. Male SD rats (4\u202fweeks old, n\u202f=\u202f24) were acclimatized for 7\u202fdays and randomized into four groups receiving CdCl\u2082 at doses of 0, 0.5, 1, or 2\u202fmg/kg for 14 consecutive days. A second cohort (n\u202f=\u202f36) was similarly allocated to six groups: control, Cd, 4-PBA, Cd\u202f+\u202f4-PBA, CQ and Cd\u202f+\u202fCQ. All treatments were administered via daily intraperitoneal injection throughout the study. On day 14, blood and liver tissues were collected for analyses of liver function, hematological parameters, and histopathology. The expression of target factors was analyzed via qRT-PCR and Western blotting. Results indicate that Cd exposure causes liver injury and disordered hepatocyte morphology. ERS markers Grp78 and Caspase-12 and autophagy-related factors Beclin-1, Atg5, P62 and LC3 are upregulated at both mRNA and protein levels. The endoplasmic reticulum-phagy (ER-phagy) receptor FAM134B and the apoptosis effector cleaved Caspase3 are upregulated at the protein level. These findings indicate that Cd induces ERS, UPR activation, autophagy, reticulophagy, and apoptosis. The ERS inhibitor 4-PBA markedly attenuated Cd-induced hepatic injury. Compared with the Cd group, the Cd\u202f+\u202f4-PBA group showed decreased serum ALT and AST levels, as well as reduced RBC, WBC, MCH, and MCV counts. At the molecular level, mRNA and protein expression of ER stress markers Grp78, Caspase-12, PERK, eIF2\u03b1, ATF4, IRE1\u03b1, JNK, and ATF6 were all downregulated. Protein levels of the ER-phagy receptor FAM134B and the apoptosis effector cleaved Caspase-3 were also decreased. The autophagy inhibitor CQ aggravated such injury. Compared with the Cd group, the Cd\u202f+\u202fCQ group showed increased serum ALT and AST levels, as well as elevated RBC, MCH, and MCV counts. At the protein level, expression of the autophagy-related factors P62 and LC3, and the apoptosis effector cleaved Caspase-3 was significantly increased. These results show that Cd-induced ERS activates autophagy and reticulophagy mainly via the PERK, IRE1\u03b1, and ATF6 pathways, and this adaptive response clears autophagic substrates to alleviate hepatocyte damage."

These findings establish FAM134B downregulation as an upstream pathogenic event in AD, suggesting ER-phagy enhancement as a promising strategy to suppress A\u03b2 generation at its source."

Codonopsis pilosula is the sovereign herb in Shenling Baizhu Formula for ulcerative colitis therapy, and Codonopsis pilosula polysaccharides are its key active components, while their immunomodulatory effects and molecular mechanisms in Shenling Baizhu Formula against ulcerative colitis remain elusive. This study explored the critical role of Codonopsis pilosula polysaccharides and the spermidine-AMPK-mediated mitophagy-cGAS-STING inflammatory axis in regulating intestinal inflammation and ameliorating ulcerative colitis. A dextran sulfate sodium-induced ulcerative colitis mouse model was established to evaluate the indispensable role of Codonopsis pilosula polysaccharides in Shenling Baizhu Formula. Ultra-high performance liquid chromatography metabolomics and 16S ribosomal RNA sequencing were performed to identify key metabolites and gut microbiota. In vitro dextran sulfate sodium-induced ulcerative colitis cellular models (human colorectal adenocarcinoma Caco-2 and human normal colonic epithelial NCM460 cells) were constructed to validate the regulatory mechanism of spermidine on AMPK-mediated mitophagy, inflammatory balance and intestinal epithelial injury. Codonopsis pilosula polysaccharides were essential for the anti-ulcerative colitis efficacy of Shenling Baizhu Formula: removal of Codonopsis pilosula significantly aggravated colonic pathological lesions, intestinal inflammatory responses and oxidative stress in ulcerative colitis mice, whereas Codonopsis pilosula polysaccharides supplementation reversed these abnormal phenotypes (P\u00a0<\u00a00.05). Metabolomics and microbiomics confirmed that Codonopsis pilosula polysaccharides exerted therapeutic effects via spermidine (a key metabolite in glutamate metabolism pathway) and Muribaculaceae. Critically, in vitro dual-cell experiments verified that spermidine activated AMPK-mediated mitophagy to directly inhibit the hyperactivation of cGAS-STING inflammatory axis, thereby restoring intestinal inflammatory homeostasis and alleviating epithelial cell injury in ulcerative colitis. Codonopsis pilosula polysaccharides extracted from the sovereign herb Codonopsis pilosula in Shenling Baizhu Formula ameliorate dextran sulfate sodium-induced ulcerative colitis, and the core mechanism depends on spermidine-triggered AMPK-mediated mitophagy to suppress the cGAS-STING inflammatory signaling axis, which plays a pivotal role in regulating intestinal immunity and repairing mucosal epithelial damage."

Spermidine (SPD), a natural polyamine known to enhance autophagy and preserve cardiac function in aging and metabolic disorders, has not been systematically evaluated in the context of septic cardiomyopathy. To determine the therapeutic potential and mechanistic basis of SPD in septic cardiac dysfunction. Network pharmacology, RNA sequencing, a cecal ligation and puncture (CLP) mouse model, and multiple cellular assays were integrated to assess the protective actions of SPD. Mitochondrial function, mitophagy flux, and oxidative stress were evaluated using transmission electron microscopy (TEM), immunohistochemistry (IHC), Western blotting, structured illumination microscopy (SIM), mitochondrial membrane potential assays, oxygen consumption rate (OCR) analysis, and mitochondrial DNA (mtDNA) quantification. Transcriptomic clustering and pathway enrichment identified molecular targets, which were validated through siRNA-mediated gene silencing. SPD markedly attenuated SICM in vivo and in vitro by improving both mitochondrial quantity and quality. It restored sepsis-impaired mitophagy by upregulating LC3B and ATG7, promoting autophagosome maturation, and enhancing cellular ubiquitination. Transcriptomic profiling highlighted metallothionein-1 (MT1) as a key node in metal-ion response pathways. SPD activated the NRF2-MT1-SOD2 antioxidant axis, reduced mitochondrial reactive oxygen species (mtROS) under lipopolysaccharide (LPS) stimulation, and reversed sepsis-induced suppression of SOD2. MT1 knockdown abolished SPD-mediated SOD2 stabilization and mtROS clearance, confirming its essential role in SPD's cardioprotective effects. SPD mitigates SICM by orchestrating the restoration of mitochondrial quality control, normalization of mitophagic flux, and stabilization of cellular redox homeostasis. These findings support SPD as a promising therapeutic candidate for septic cardiomyopathy."

Here we show that in steroid receptor coactivator (Src)-1 and -2 double-knockout mice, reduced placental amine oxidase, copper-containing 1 (Aoc1) leads to increased spermidine levels.

AOC1 levels are elevated in preterm labor placentas from both mice and humans. Placenta-specific Aoc1 knockout dramatically delays labor by increasing trophoblast autophagy.

Adult SD rats were randomized into Sham operation, PSCI model, TTM, rapamycin (an autophagy inducer), 3-methyladenine (an autophagy inhibitor), and TTM+3-MA groups, and rat models of cognitive impairment were established using a modified thread occlusion method. Cognitive function of the rats was assessed using Morris water maze test. Histopathological changes, neuronal apoptosis, dendritic spines, and protein expressions of FAM134B, LC3, ATG5, P62, GRP78, Bax, Bcl-2, IL-10, IL-1\u03b2, and TNF-\u03b1 were evaluated using HE, Nissl, TUNEL, Golgi staining, immunohistochemistry, immunofluorescence staining, and Western blotting. Compared with the sham-operated rats, the rat models of PSCI showed significantly prolonged escape latency, reduced target quadrant time and platform crossings, severe hippocampal damage, increased ATG5 and GRP78 expression, elevated apoptosis, increased IL-1\u03b2, TNF-\u03b1, Bax, GRP78, and P62 expressions, and decreased IL-10, Bcl-2, and LC3 expressions, with slightly increased FAM134B-LC3 and calnexin-LC3 co-localization. Compared with those in the model group, the rats receiving TTM treatment showed significantly shortened escape latency, increased target quadrant time and platform crossings, increased ATG5 and dendritic spines, decreased GRP78 expression, enhanced FAM134B-LC3 and calnexin-LC3 co-localization, reduced IL-1\u03b2, TNF-\u03b1, Bax, GRP78, and P62 expressions, and increased FAM134B, ATG5, LC3, IL-10, and Bcl-2 expressions; the rats treated with 3-MA showed the opposite changes. Excessive ER stress is activated early after stroke, shifting from adaptive to pro-apoptotic signaling, with insufficient ER-phagy flux. TTM modulates ER-phagy, alleviates ERS, reduces neuroinflammation and apoptosis, protects dendritic spines, and improves cognitive function in rats with PSCI. \u76ee\u7684:

"abstract_text": "ID: 42107477\nTitle: Nano-selenium attenuates cadmium-induced ER-phagy through inhibition of TFEB nuclear translocation and FAM134B downregulation.\nAbstract: Cadmium (Cd) is a well-documented environmental pollutant associated with male reproductive disorders, necessitating the urgent development of effective therapeutic agents. Nano-selenium (Nano-Se) represents an advanced selenium supplement with robust antioxidant properties, which can mitigate various forms of heavy metal toxicity. However, the role of Nano-Se in alleviating Cd-induced testis damage remains unclear. Family with sequence similarity 134 member B (FAM134B) is the first identified Endoplasmic reticulophagy (ER-phagy) receptor, and the ER-phagy it mediates plays a crucial role in the reproductive system. In this study, Hy-line White roosters were randomly divided into four groups and subjected to a 90-day observation period. Serum samples and testicular tissue samples from roosters were collected for subsequent detection. Hematoxylin-eosin (H&E) staining, periodic acid-Schiff (PAS) staining, ELISA kit detection, Western blotting (WB), immunofluorescence (IF), cellular thermal shift assay (CETSA) and molecular docking techniques were employed to explore the effects of Cd on the reproductive system and the alleviating effect of Nano-Se. In vivo assays revealed that Nano-Se efficiently mitigated testicular atrophy and histological damage triggered by Cd exposure. Nano-Se reversed the Cd-mediated inhibition of steroidogenesis-related proteins, and elevated the expression of Leydig cell markers including 3\u03b2-HSD and INSL3, thereby ameliorating Cd-evoked Leydig cell dysfunction. Consistent with in vivo outcomes, in vitro tests using primary rooster Leydig cells demonstrated that Nano-Se notably restrained Cd-activated ER-phagy and excessive lysosomal acidification. Mechanistically, such protective effects were achieved by blocking TFEB nuclear translocation and preventing the downregulation of FAM134B. This present study provides a foundation for preclinical research for its usefulness as a potential therapeutic for reproductive toxicity induced by environmental heavy metal pollutants."

Here, using state-of-the-art super-resolution multi-SIM imaging, we reveal that stresses (prolonged starvation, cholesterol dyshomeostasis, and high-Ca2+ insults) trigger the expansion of sheet ER subdomains containing high levels of luminal Ca2+ in mammalian cells, which are subsequently degraded by ER-phagy. Autophagosome formation and sequestration of ER sheets require the concerted actions of FAM134B and lipidated LC3, whereas the autophagy proteins ATG14 and ATG9 are partially dispensable. Electron microscopy and cryo-electron tomography show that the membranes of autophagosomes enclosing high-Ca2+-containing ER sheets are directly remodeled from the ER. The ER-localized cation channels PIEZO1 and TRPV1 are enriched at and mediate Ca2+ transients from high-Ca2+-containing ER sheets, triggering liquid-liquid phase separation of the autophagosome-initiating FIP200 complex to initiate ER-phagy. Thus, distinct mechanisms are employed for the formation of high-Ca2+-containing ER-enclosing autophagosomes and non-selective autophagosomes."

Previously, the 1st known ER-phagy receptor gene RETREG1 (RETR1)/FAM134B gene was reported to restrict Ebola virus (EBOV) replication in vivo by inhibiting the viral glycoprotein (GP) and viral protein 40 kDa (VP40) expression, but this mechanism remains unknown. Here, we identify the truncated RETR1/FAM134B isoform 2 (RETR1-2), but not its full-length protein RETR1, as an ER-phagy receptor that targets EBOV-GP for degradation. RETR1-2 broadly triggers GP degradation across ebolavirus species but not Marburg virus and inhibits EBOV replication. Mechanistically, RETR1-2 recognizes EBOV-GP via its luminal domain, undergoes GP-induced oligomerization, and directs GP-containing ER membranes to lysosomes through canonical macro-autophagy. Using unbiased mass spectrometry, we identified TOLLIP as the key cytoplasm adaptor for RETR1-2, which also requires cooperation with the ER chaperone calnexin for EBOV-GP degradation. Notably, the PI3P-binding C2 domain of TOLLIP mediates its interaction with RETR1-2, and the EBOV-GP degradation occurs independently of ubiquitination, revealing an unexpected role for TOLLIP in ER-phagy. Furthermore, EBOV-VP40 antagonizes this pathway by selectively targeting RETR1-2 for macroautophagic degradation independently of TOLLIP, thereby restoring GP expression and viral infectivity. Nevertheless, RETR1-2 reciprocally degrades VP40 via a similar mechanism. Together, these findings define a calnexin-TOLLIP-RETR1-2 axis that links ER quality control to ER-phagy-mediated antiviral restriction and uncover a reciprocal host-virus arms race centered on selective macro-autophagy."

MARCH6 and FAM134B expression levels were measured in glioma tissues. A comparative analysis was conducted on the correlation between clinical parameters and FAM134B expression in 46 glioma patients. FAM134B and MARCH6 were knocked down in glioma cells, followed by detection of cell viability and apoptosis, typical ER stress (ERS) markers (PERK, IRE1\u03b1, eIF2\u03b1, and CHOP), autophagy-related proteins (P62 and LC3B), and autophagosome cytoplasmic accumulation. A mouse glioma model was established for in vivo validation. MARCH6-FAM134B interaction, FAM134B ubiquitination levels, and protein stability were examined. FAM134B expression was high and MARCH6 expression was low in glioma tissues. MARCH6 induced FAM134B protein ubiquitination and degradation, reducing its stability in glioma cells. Knockdown of FAM134B reduced glioma cell survival, inhibited PERK, IRE1\u03b1, eIF2\u03b1, and CHOP expression, decreased LC3I to LC3II conversion, lowered LC3B fluorescence expression, and reduced the accumulation of autophagosomes with continuous ER structures in the cytoplasm, while enhancing apoptosis and P62 expression. This effect can be reversed by knocking down MARCH6. In vivo, FAM134B knockdown suppressed tumorigenesis in mice. MARCH6 exerts a repressive effect on ERS responses and ER-phagy in glioma cells by destabilizing FAM134B."

Endoplasmic reticulum (ER) stress and autophagy are two interconnected stress responses critical for maintaining cellular homeostasis. Berbamine (BBM) is an important member of bis-benzy lisoquinoline alkaloid with diverse biological activities. This study aimed to identify the molecular target of BBM against T-2 toxin-induced hepatotoxicity, focusing on autophagy-ER stress crosstalk. We systematically evaluated autophagy and ER stress in human HepaRG cells using immunoblotting, transmission electron microscopy and an autophagy reporter assay. T-2 toxin was found to concurrently activate PINK1/Parkin-mediated mitophagy and suppress Keap1-mediated FAM134B ubiquitination-dependent ER-phagy, thereby triggering ER stress. Integrated evidence from molecular dynamics and western blot demonstrated that BBM upregulated and stabilized BNIP3, blocking the VAMP8-SNAP29 interaction to inhibit T-2 toxin-induced autophagy and subsequent ER stress. Moreover, in vivo mouse experiments demonstrated that 30\u202fmg/kg BBM significantly alleviated T-2 toxin-induced liver injury by suppressing both autophagic flux and ER stress; BBM significantly reduced serum levels of liver enzymes, ALT, and AST. Collectively, our findings elucidate a novel mechanism wherein T-2 toxin-induced mitophagy inhibits ER-phagy to drive ER stress-mediated liver injury and highlight the therapeutic potential of BBM in alleviating T-2 toxin-induced liver injury."

This review summarizes current knowledge on spermidine biology, including its synthesis, catabolism, transport, and cell-specific handling in neurons and glia, with emphasis on ATP13A2/ATP13A4-dependent trafficking and EP300-linked autophagy. Preclinical studies consistently show that spermidine enhances proteostasis, reduces soluble amyloid-beta, improves microglial phagocytic activity, preserves mitochondrial fitness, and attenuates inflammatory responses in models of aging and neurodegeneration. Human evidence is encouraging but still limited: observational studies associate higher dietary spermidine intake with better cognitive outcomes, whereas interventional trials suggest possible benefits in subjective cognitive decline and mild dementia, with variable dose-dependent effects. Overall, spermidine is a biologically plausible nutraceutical for healthy brain aging, but larger, well-designed clinical trials are needed to define efficacy, bioavailability, safety, and optimal therapeutic use across prodromal, early-stage, and disease-specific patient populations."

The nuclear factor erythroid 2-related factor 2 (Nrf2) pathway plays a central role in regulating cellular antioxidant defences against UV-induced damage. This scoping review aims to evaluate the potential role of sulforaphane (SFN), a known Nrf2 inducer, in protecting against UV-induced skin damage and photocarcinogenesis. Methods: A literature search was conducted in PubMed and Scopus from inception to 27 January 2026, to identify original experimental studies investigating SFN, glucoraphanin, or broccoli sprout extracts in the context of UV-induced skin damage. Eligible studies included in vitro, ex vivo, in vivo, and human models assessing outcomes related to oxidative stress, inflammation, molecular signalling pathways, and tumour development. Following screening and eligibility assessment, twelve studies were included in the qualitative synthesis. Results: The included studies suggest that SFN exerts photoprotective effects across multiple experimental models. In murine studies, SFN and SFN-rich extracts were associated with a reduction in tumour incidence, multiplicity, and volume following UV exposure. In human studies, topical SFN application reduced UV-induced erythema and induced cytoprotective enzyme expression, although clinical evidence remains limited. Mechanistically, SFN consistently activated the Nrf2 pathway, leading to increased expression of antioxidant and phase II detoxifying enzymes, and was associated with modulation of inflammatory responses and inhibition of MAPK/AP-1 signalling. Emerging evidence also indicates potential effects on UV-induced metabolic and epigenetic alterations. Conclusions: Current evidence supports a potential role for sulforaphane in mitigating UV-induced skin damage through activation of endogenous defence pathways. However, the available data are predominantly preclinical, and further well-designed clinical studies are needed to clarify its efficacy and translational relevance in humans."

This study investigates the neuroprotective potential of Sulforaphane (SFN) in ameliorating ethidium bromide (EBRM)-induced MS-like pathology in Wistar rats. The efficacy of SFN at two doses (SFN1.5 and SFN3) was compared to FDA-approved Nrf2 activator drugs, omaveloxolone (OMV15) and dimethyl fumarate (DIMF50). EBRM administration caused neurobehavioral deficits, demyelination, oxidative stress, axonal degeneration, and inflammation. It disrupted key cellular pathways, including Nrf2/HO-1/SIRT-1, JAK/STAT-3/mTOR, and BACE-1/Gamma-secretase/MAPT, as well as caused neurotransmitter imbalances. SFN3 demonstrated significant improvement in motor function, cognitive performance, neurotransmitter levels antioxidant enzymes and alleviated neuroinflammation by modulating inflammatory cytokines. Molecular analyses showed that SFN3 increased Nrf2/HO-1/SIRT-1 levels while decreased pro-inflammatory and neurodegenerative markers such as STAT-3, mTOR, and BACE-1 levels. Gross pathological, Histopathological, and LFB studies indicated reduced demyelination and liver damage. SFN3 also demonstrated favourable systemic safety compared to OMV15. While DIMF50 showed the highest overall efficacy, SFN3 showed consistent modulation of pathological markers, neuroprotective effects, and safety profile. These findings suggest that SFN3 may have therapeutic potential for further translational research in MS. Future studies should validate its clinical relevance and explore combinatorial therapies with existing MS treatments to enhance therapeutic outcomes."

Downregulation of EAAT2 results in glutamate accumulation, N-Methyl-D-Aspartate (NMDA) receptor overactivation, and neuronal injury. Crocin (Cr), a carotenoid compound extracted from saffron (Crocus sativus), exhibits potent antioxidant and neuroprotective properties, particularly in experimental models of neurodegeneration. Forty-eight adult male rats were divided into six groups: control (saline), crocin (50\u00a0mg/kg), scopolamine (3\u00a0mg/kg for 7 days), scopolamine followed by memantine (M) (20\u00a0mg/kg), scopolamine followed by crocin, and scopolamine followed by both memantine and crocin. This study aimed to evaluate the therapeutic potential of crocin, alone and in combination with memantine, in a scopolamine-induced rat model of Alzheimer's disease, with a focus on EAAT2 modulation. Scopolamine administration significantly elevated glutamate, NMDAR and p-tau levels while reducing p-Akt, GABA and EAAT2 levels, accompanied by marked hippocampal neurodegeneration.

Alginate oligosaccharide (AOS), a marine-derived bioactive polysaccharide, exhibits prebiotic, anti-inflammatory and antioxidant properties that are effective against various inflammatory diseases. In this study, a mouse model of SAP was established by intraperitoneal injection of cerulein (100 \u03bcg/kg) and lipopolysaccharide (5 mg/kg), and the mice were pretreated with AOS (200 mg/kg) by gavage for 4 consecutive weeks to explore the potential protective efficacy and underlying mechanisms. The results shown that AOS attenuated the severity of SAP, as evidenced by reduced serum amylase and lipase levels, as well as alleviated histopathological injury in both pancreatic and ileal tissues. AOS suppressed the overproduction of pro-inflammatory cytokines (IL-1\u03b2, IL-6, TNF-\u03b1) in serum, pancreas, and ileum at protein or mRNA levels. Moreover, AOS effectively diminished pancreatic and ileal inflammatory infiltration and oxidative stress in SAP mice, accompanied by inhibited the TLR4/MyD88/NF-\u03baB pathway and activated the Nrf2/HO-1 antioxidant axis. Furthermore, AOS restored intestinal barrier integrity, as manifested by upregulated expression of tight junction proteins (claudin-1, occludin, ZO-1), reduced serum diamine oxidase, and decreased bacterial translocation from the gut to the pancreas. It was revealed by 16S rRNA sequencing that AOS ameliorated SAP-induced gut dysbiosis by restoring microbial diversity, normalizing the Firmicutes/Bacteroidetes ratio, enriching beneficial genera (Lactobacillus, Blautia), and enhancing cecal short-chain fatty acid (acetic, propionic, butyric acid) production. Collectively, our findings demonstrate that AOS exerts comprehensive protective effects against SAP through suppression of inflammatory signaling and oxidative stress, as well as restoring gut homeostasis. These results suggest that AOS may serve as a promising prebiotic-based nutritional strategy for the management of SAP."

Spermidine has been shown to counteract immunosenescence and induce autophagy in preclinical models, and its levels decline with age in humans. We conducted a double-blind, randomised, placebo-controlled pilot study in 40 adults over 65\u2009years of age following their third SARS-CoV-2 vaccine dose to assess the safety of Spermidine and its effects on vaccine-induced immunity. Daily oral supplementation (6\u2009mg, 13\u2009weeks) was well-tolerated. Vaccine non-responsiveness was common, and non-responders exhibited a distinct immune-senescence signature marked by elevated p16, mTOR signalling, and \u03b3-H2AX+ DNA damage in lymphocytes. Spermidine reversed these features and significantly enhanced spike-specific IgG secretion, memory B cell recall responses and neutralising antibody activity, specifically in non-responders. Single-cell RNA-seq after treatment revealed increased expression of TFEB targets and autophagy-related genes in B cells, in line with elevated autophagic flux.

Clostridium butyricum (C. butyricum), a probiotic, can alleviate cognitive decline in individuals with various neurodegenerative diseases, and C. butyricum might generate SPD. However, the role of C. butyricum in natural brain aging and the efficacy of C. butyricum and the metabolite SPD in ameliorating age-related cognitive decline remain unclear.

To our knowledge, no prior systematic review has synthesized evidence linking these metabolites to direct mitochondrial endpoints across all major metabolite classes. PubMed, Scopus, and Web of Science were systematically searched through March 2026 for studies examining direct mitochondrial endpoints in relation to ten classes of gut-derived metabolites. Gut-derived microbial metabolites exert diverse effects on mitochondrial function, ranging from bioenergetic enhancement to direct toxicity. After contextual evidence was excluded from the certainty assessment, four metabolite-mitochondrial outcome groupings had moderate certainty: butyrate, propionate, indoxyl sulfate, and lipopolysaccharide.

Polyamines, including putrescine, spermidine, and spermine, are vital microbial-host metabolites that support intestinal cell growth, autophagy, immune modulation, and mucosal repair. With advancing age, both host-derived and microbiota-mediated polyamine production declines, contributing to intestinal dysfunction and heightened vulnerability to inflammation and age-related disorders. This review explores the diet-microbiota-polyamine axis as a key biological framework influencing intestinal aging. It aims to integrate evidence on how dietary components and functional foods shape gut microbial ecology and, in turn, regulate microbial polyamine biosynthetic pathways that impact intestinal health. The review highlights major microbial contributors to polyamine metabolism, particularly lactic acid bacteria, and outlines mechanistic pathways linking polyamines to epithelial regeneration, inflammatory control, and gut barrier maintenance. It further discusses how age-associated dysbiosis disrupts these interactions and evaluates nutritional and microbial-based strategies such as fermented foods, prebiotics, and probiotics that may enhance polyamine availability and restore gut homeostasis. From the standpoint of food microbiology and human physiology, this synthesis underscores the translational potential of targeting microbial polyamine production through diet-based interventions. This article presents a narrative review synthesizing experimental, animal, and emerging human evidence on microbial and dietary polyamines in intestinal aging. In conclusion, modulating the diet-microbiota-polyamine axis represents a promising strategy to promote healthy intestinal aging, meriting deeper mechanistic exploration and validation through clinical studies."

Specifically, SS-31 remarkably restored the normal spindle/chromosome structure, fertilization ability, mitochondrial distribution, \u0394\u03a8m and mitophagy in aged oocytes.

In addition, SS-31 suppressed chromatin organization, histone modification and chromatin remodeling pathways. Moreover, we applied the single-cell untargeted metabolomics to identify that SS-31 increased the levels of spermidine and GSH, which were critical metabolites to protect oocytes against aging.

Here, we identify ER-phagy as a previously unrecognized adaptive response to ISOXUS, an isoxazole derivative of usnic acid with selective anticancer activity. ISOXUS, a mitochondrial respiratory complex II inhibitor, induces bioenergetic collapse, reactive oxygen species accumulation, and extensive ER-derived vacuolization. Using integrated transcriptomic and metabolomic analyses, we demonstrate that ISOXUS selectively triggers ER-phagy in mitochondria-dependent MCF-7 breast cancer cells, but not in more glycolytic triple-negative MDA-MB-231 cells, revealing a cell-type-specific stress adaptation program. ER-phagy induction is associated with upregulation of the ER-phagy receptor FAM134B and depends on ER stress signalling, as pharmacological ER stress inhibition suppresses this process. Multi-omics profiling uncovers coordinated repression of mitochondrial gene expression together with activation of ER-centered metabolic pathways, including amino acid metabolism, the tricarboxylic acid cycle, and one-carbon folate metabolism. Notably, we also identify UFMylation-related genes (CDK5RAP3, DDRGK1) as novel candidates involved in ER-phagy induced by ISOXUS. Moreover, mitochondrial inhibitors, rotenone and oligomycin, unexpectedly promote, while antioxidant a-tocopherol blocks ISOXUS-induced ER-phagy, and all compounds partially improve cell viability under ISOXUS treatment, implicating ROS-driven ER-phagy as a cytoprotective mechanism. Integrated analyses further reveal activation of the integrated stress response (ISR), dominated by the PERK-ATF4 axis, driving glutamine-dependent metabolic reprogramming and suppression of apoptosis-related pathways. The late-stage autophagy inhibition lowered the glutathione synthesis after ISOXUS treatment. Collectively, our findings uncover a previously unappreciated mitochondria-ER-ISR axis that governs metabolic adaptation to ISOXUS and identifies ER-phagy as a potential therapeutic vulnerability in breast cancer."

Spermidine (SPD), a natural polyamine known to enhance autophagy and preserve cardiac function in aging and metabolic disorders, has not been systematically evaluated in the context of septic cardiomyopathy. To determine the therapeutic potential and mechanistic basis of SPD in septic cardiac dysfunction. Network pharmacology, RNA sequencing, a cecal ligation and puncture (CLP) mouse model, and multiple cellular assays were integrated to assess the protective actions of SPD. Mitochondrial function, mitophagy flux, and oxidative stress were evaluated using transmission electron microscopy (TEM), immunohistochemistry (IHC), Western blotting, structured illumination microscopy (SIM), mitochondrial membrane potential assays, oxygen consumption rate (OCR) analysis, and mitochondrial DNA (mtDNA) quantification. Transcriptomic clustering and pathway enrichment identified molecular targets, which were validated through siRNA-mediated gene silencing. SPD markedly attenuated SICM in vivo and in vitro by improving both mitochondrial quantity and quality. It restored sepsis-impaired mitophagy by upregulating LC3B and ATG7, promoting autophagosome maturation, and enhancing cellular ubiquitination. Transcriptomic profiling highlighted metallothionein-1 (MT1) as a key node in metal-ion response pathways. SPD activated the NRF2-MT1-SOD2 antioxidant axis, reduced mitochondrial reactive oxygen species (mtROS) under lipopolysaccharide (LPS) stimulation, and reversed sepsis-induced suppression of SOD2. MT1 knockdown abolished SPD-mediated SOD2 stabilization and mtROS clearance, confirming its essential role in SPD's cardioprotective effects. SPD mitigates SICM by orchestrating the restoration of mitochondrial quality control, normalization of mitophagic flux, and stabilization of cellular redox homeostasis. These findings support SPD as a promising therapeutic candidate for septic cardiomyopathy."

As an important carbohydrate, starch directly affects the homeostasis of glucose and lipid metabolism due to its digestion characteristics. Resistant starch (RS) with unique anti-digestive properties and prebiotic functions has become the current hotspot in dietary nutrition research for improving glucose and lipid metabolism disorders. This review summarizes the digestive characteristics of starch and the comprehensive effects of RS and its mechanisms for ameliorating metabolic diseases. Diets with high RS content not only optimize glucose homeostasis by delaying glucose release, the undigested fractions entering the colon also drive the metabolic regulatory network of the gut microbiota-gut-brain axis by activating the AMPK/ACC pathway to reduce fat accumulation, enhancing intestinal barrier function mediated by short-chain fatty acids (SCFAs), and promoting GLP-1/PYY neural signal transduction. These insights facilitate the design of new healthy foods and inspire new strategies for optimizing dietary nutrition and regulating glucose and lipid metabolism disorders caused by high-carbohydrate diets. \u4ee3\u8c22\u6027\u75be\u75c5\u5982\u80a5\u80d6\u3001\u7cd6\u5c3f\u75c5\u3001\u5fc3\u8840\u7ba1\u75be\u75c5\u7684\u5168\u7403\u6d41\u884c\u4e0e\u8425\u517b\u8fc7\u5269\u53ca\u996e\u98df\u6a21\u5f0f\u5931\u8861\u5bc6\u5207\u76f8\u5173\u3002\u6dc0\u7c89\u4f5c\u4e3a\u4eba\u7c7b\u4e3b\u8981\u80fd\u91cf\u6765\u6e90\u7684\u78b3\u6c34\u5316\u5408\u7269\uff0c\u5176\u6d88\u5316\u7279\u6027\u76f4\u63a5\u5f71\u54cd\u7cd6\u8102\u4ee3\u8c22\u7a33\u6001\u3002\u6297\u6d88\u5316\u6027\u6dc0\u7c89\uff08RS\uff09\u56e0\u5176\u72ec\u7279\u7684\u6297\u6d88\u5316\u7279\u6027\u4e0e\u76ca\u751f\u5143\u529f\u80fd\uff0c\u6210\u4e3a\u5f53\u524d\u6539\u5584\u7cd6\u8102\u4ee3\u8c22\u7d0a\u4e71\u7684\u81b3\u98df\u8425\u517b\u7814\u7a76\u7684\u70ed\u70b9\u3002\u672c\u6587\u7efc\u8ff0\u4e86\u6dc0\u7c89\u6d88\u5316\u7279\u6027\u4ee5\u53caRS\u6539\u5584\u4ee3\u8c22\u6027\u75be\u75c5\u7684\u7efc\u5408\u4f5c\u7528\u53ca\u76f8\u5173\u673a\u5236\u3002\u9ad8RS\u7684\u81b3\u98df\u4e0d\u4ec5\u901a\u8fc7\u5ef6\u7f13\u8461\u8404\u7cd6\u91ca\u653e\u4f18\u5316\u8840\u7cd6\u7a33\u6001\uff0c\u800c\u4e14\u672a\u6d88\u5316\u7684\u90e8\u5206\u8fdb\u5165\u7ed3\u80a0\u901a\u8fc7\u9a71\u52a8\u80a0\u9053\u83cc\u7fa4-\u80a0-\u8111\u8f74\u4ee3\u8c22\u8c03\u63a7\u7f51\u7edc\uff0c\u5176\u4e2d\u5305\u62ec\u6fc0\u6d3b\u817a\u82f7\u9178\u6d3b\u5316\u86cb\u767d\u6fc0\u9176/\u4e59\u9170\u8f85\u9176A\u7fa7\u5316\u9176\uff08AMPK/ACC\uff09\u901a\u8def\u51cf\u5c11\u8102\u80aa\u84c4\u79ef\u3001\u63d0\u5347\u77ed\u94fe\u8102\u80aa\u9178\uff08SCFAs\uff09\u4ecb\u5bfc\u7684\u80a0\u5c4f\u969c\u529f\u80fd\u4e0e\u80f0\u9ad8\u8840\u7cd6\u7d20\u6837\u80bd-1/\u80bdYY\uff08GLP-1/PYY\uff09\u795e\u7ecf\u4fe1\u53f7\u4f20\u5bfc\u3002\u8fd9\u4e0d\u4ec5\u5c06\u4e3a\u65b0\u578b\u5065\u5eb7\u98df\u54c1\u8bbe\u8ba1\u63d0\u4f9b\u7814\u7a76\u57fa\u7840\uff0c\u4e5f\u4e3a\u4f18\u5316\u81b3\u98df\u8425\u517b\uff0c\u8c03\u63a7\u9ad8\u78b3\u6c34\u996e\u98df\u5f15\u8d77\u7684\u7cd6\u8102\u4ee3\u8c22\u7d0a\u4e71\u63d0\u4f9b\u4e86\u65b0\u7684\u7814\u7a76\u601d\u8def\u3002."

To address this question, we investigated a monogenic form of epilepsy (pyridoxine-dependent epilepsy) caused by aldehyde dehydrogenase 7 family member A1 (ALDH7A1) mutations. ALDH7A1 global knockout mice exhibited both seizure-associated and maladaptive affective behavioral phenotypes. However, seizure phenotypes were caused by ALDH7A1 deletion in hepatocytes whereas maladaptive affective behaviors were caused by ALDH7A1 deletion in astrocytes. Deletion in astrocytes disrupted astrocyte redox homeostasis, impairing regulation of extracellular ion concentrations and reducing neuronal activity in the prelimbic cortex. Sulforaphane, which activates the NRF2 antioxidant pathway, restored prelimbic neuronal activity and rescued maladaptive affective behaviors in ALDH7A1 knockout mice but did not prevent seizures. These studies implicate astrocyte redox homeostasis and prelimbic hypoactivity in maladaptive affective behavioral phenotypes in a congenital form of epilepsy, which are mechanistically and therapeutically dissociable from seizure pathophysiology."

Although PFOS exposure causes significant bioaccumulation and potential myelotoxicity, its specific impact on the chondrogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) remains to be elucidated. In this study, we established a murine model of PFOS exposure to isolate primary BMSCs and investigated this issue through in vitro differentiation assays, cellular senescence evaluations, and an in vivo subcutaneous implantation model using gelatin methacryloyl (GelMA) hydrogel scaffolds. Our results demonstrated that PFOS exposure triggered intracellular reactive oxygen species (ROS) accumulation and induced a senescent phenotype in BMSCs, characterized by restricted cellular proliferation and the release of senescence-associated secretory phenotype (SASP) factors, thereby markedly suppressing their chondrogenic capacity. Mechanistically, the inhibition of the Nrf2 signaling pathway by PFOS was identified as the principal driver of this process. Furthermore, both in vitro and in vivo assays confirmed that pharmacological activation using the Nrf2 agonist sulforaphane (SFN) effectively mitigated the senescent phenotype and restored the chondrogenic potential of PFOS-exposed BMSCs. Altogether, these findings elucidate the specific mechanisms of PFOS-induced stem cell toxicity and offer a potential strategy to overcome the resulting limitations in BMSC-based cartilage regeneration."

"abstract_text": "ID: 42346630\nTitle: Sulforaphane as a Photoprotective Agent Against UV-Induced Skin Damage and Carcinogenesis: A Scoping Review.\nAbstract: Background/Objectives: Ultraviolet (UV) radiation is a major environmental carcinogen responsible for skin damage through oxidative stress, DNA damage, and inflammation. The nuclear factor erythroid 2-related factor 2 (Nrf2) pathway plays a central role in regulating cellular antioxidant defences against UV-induced damage. This scoping review aims to evaluate the potential role of sulforaphane (SFN), a known Nrf2 inducer, in protecting against UV-induced skin damage and photocarcinogenesis. Methods: A literature search was conducted in PubMed and Scopus from inception to 27 January 2026, to identify original experimental studies investigating SFN, glucoraphanin, or broccoli sprout extracts in the context of UV-induced skin damage. Eligible studies included in vitro, ex vivo, in vivo, and human models assessing outcomes related to oxidative stress, inflammation, molecular signalling pathways, and tumour development. Following screening and eligibility assessment, twelve studies were included in the qualitative synthesis. Results: The included studies suggest that SFN exerts photoprotective effects across multiple experimental models. In murine studies, SFN and SFN-rich extracts were associated with a reduction in tumour incidence, multiplicity, and volume following UV exposure. In human studies, topical SFN application reduced UV-induced erythema and induced cytoprotective enzyme expression, although clinical evidence remains limited. Mechanistically, SFN consistently activated the Nrf2 pathway, leading to increased expression of antioxidant and phase II detoxifying enzymes, and was associated with modulation of inflammatory responses and inhibition of MAPK/AP-1 signalling. Emerging evidence also indicates potential effects on UV-induced metabolic and epigenetic alterations. Conclusions: Current evidence supports a potential role for sulforaphane in mitigating UV-induced skin damage through activation of endogenous defence pathways. However, the available data are predominantly preclinical, and further well-designed clinical studies are needed to clarify its efficacy and translational relevance in humans."

This narrative review synthesizes preclinical and early clinical evidence on the mechanisms and therapeutic applicability of SFN in ICU-acquired weakness, diabetic myopathy, sarcopenia, and exercise-induced muscle damage. SFN modulates skeletal muscle pathophysiology through four interconnected axes: regulation of protein homeostasis via mTOR-associated signaling and suppression of ubiquitin-proteasome-mediated catabolism; upregulation of oxidative stress defenses through Nrf2-driven antioxidant enzyme induction; attenuation of inflammatory networks via NF-\u03baB inhibition and promotion of M2 macrophage polarization; and metabolic reprogramming through AMPK-mediated mitochondrial biogenesis and enhanced insulin sensitivity. Preclinical data suggest preliminary protective effects on respiratory and locomotor muscle; however, clinical translation remains uncertain. Several randomized controlled trials have failed to demonstrate significant effects on Nrf2 target genes or metabolic stress biomarkers, and bioavailability varies markedly across formulations and individuals. Heterogeneous responses across muscle fiber types, an undefined therapeutic window, and interindividual variability in gut microbiota-mediated conversion further complicate clinical application. To address these challenges, we propose a conceptual \"Sulforaphane Precision Medicine Framework\" integrating molecular biomarkers, gut microbiome profiling, and dynamic delivery systems to guide personalized intervention. While SFN shows promise as an adjunctive therapy, standardized formulations, refined patient stratification, and rigorous phase III trials are essential before routine clinical adoption can be recommended."

Here, we examined the effects of two haloacetamides, 2,2-dichloroacetamide (DCAcAm) and 2,2-dibromoacetamide (DBAcAm), on mouse oocyte maturation and identified the underlying mechanisms of toxicity. Both compounds markedly impaired meiotic spindle assembly and compromised the function of multiple organelles, including mitochondria, the endoplasmic reticulum, and the Golgi apparatus, primarily through autophagy dysregulation at specific exposure concentrations, as evidenced by the observation that more than half of the oocytes failed to progress beyond the MII stage. Spermidine supplementation effectively restored autophagic activity and rescued the associated cellular defects, thereby improving both nuclear and cytoplasmic maturation in oocytes. Collectively, these findings demonstrate that spermidine alleviates toxicant-induced deterioration of oocyte quality by regulating autophagy and highlight its potential therapeutic value for reproductive protection and clinical application."

Here, we identify the vitamin D receptor (Vdr) as a key anti-aging transcription factor whose expression in granulosa cells (GCs) declines with age. Using GCs-specific Vdr knockout (cVKO) mice and a Vdr-knockout (VKO) human granulosa-like cell line, we demonstrate that loss of Vdr triggers GCs aging and disrupts ovarian function. Integrated transcriptomic and metabolomic analyses from VKO and WT cells revealed that Vdr loss downregulates the de novo spermidine (SPD) biosynthesis by directly suppressing the transcription of ornithine decarboxylase (ODC1). This led to SPD depletion, which in turn inhibited DNA methyltransferase (DNMTs) activity, resulting in hypomethylation of the p53 promoter and activation of the p53/p21 pathway. Crucially, supplementation with either SPD or its upstream methyl donor S-adenosylmethionine (SAM) rescued cVKO and VKO cell aging, improved hormonal profiles and promoted follicular development in cVKO mice. Furthermore, both supplements effectively delayed ovarian aging and improved fertility in naturally aged mice. Our study unveils the Vdr-spermidine-DNMTs axis as a fundamental mechanism safeguarding against ovarian aging, highlighting SPD and SAM as promising therapeutic agents for age-related female infertility."

ZEN exposure induces endoplasmic reticulum (ER) stress, oxidative stress, and autophagy activation. However, the involvement of inositol-requiring enzyme 1 (IRE1)-mediated ER-phagy in ZEN-induced ER stress and embryonic competence during in vitro culture (IVC) remains unclear. Porcine embryos were cultured with 2.5, 5, and 10\u202f\u03bcM ZEN for two days after in vitro fertilization (IVF) to assess blastocyst development. ZEN exposure caused a significant dose-dependent decrease in blastocyst formation, expanded blastocysts, and total cell number (p\u202f<\u202f0.05). ZEN-treated embryos exhibited increased DNA fragmentation along with elevated mitochondrial and intracellular Ca\u00b2\u207a levels (p\u202f<\u202f0.001), as confirmed using terminal deoxynucleotidyl transferase dUTP nick-end labeling assay and Rhod-2 and Fluo-4 AM staining.

In this review we summarize the current knowledge on ER-phagy receptors, and emerging evidence linking ER-phagy dysfunction to various disease pathologies including neurological disorders, cancer, metabolic diseases, cardiovascular diseases, infections and immune disorders. Recent evidence shows that ER-phagy receptors can form novel ER-derived structures, such as ER-tubular bodies (ER-TBs) consisted of ATL3 and RTN3L, which mediate Golgi-bypassing unconventional protein secretion under stress conditions, revealing non-degradative functions of these receptors beyond quality control. Targeting ER-phagy receptors may provide insights into potential therapeutic strategies for diseases associated with this fundamental cellular process."

This study demonstrates that fecal microbiota transplantation (FMT) confers protection against RILI through modulation of the gut-lung axis. In a total lung irradiation (TLI) mouse model, FMT significantly alleviated pulmonary histopathological injury, inflammatory responses, oxidative stress, and collagen deposition during fibrogenesis. Concurrently, FMT improved intestinal motility, enhanced mucosal barrier integrity, and restored TLI-induced dysbiosis in gut microbiota diversity and community structure. Metabolomic analysis revealed that TLI significantly disrupted the metabolism of unsaturated fatty acids and arachidonic acid (AA), whereas FMT partially restored these metabolic networks. Transcriptomic and ultrastructural analyses indicated that RILI suppressed endoplasmic reticulum (ER) protein processing and induced ER swelling, while FMT promoted protective ER-phagy and facilitated restoration of ER morphology. Integrated multi-omics analysis further identified the AA metabolism as a key component of FMT-mediated protection, with its alterations closely associated with pulmonary tissue repair. Further in vivo and in vitro experiments demonstrated that AA binds to and activates the nuclear receptor PPAR\u03b3, leading to transcriptional upregulation of FAM134B, promoting protective ER-phagy and ameliorating RILI. In summary, this study highlights the bidirectional gut-lung axis as a therapeutic target in RILI progression and intervention, and reveals that FMT confers protection through metabolic remodeling and activation of the PPAR\u03b3-FAM134B-mediated ER-phagy pathway, providing a mechanistic basis for potential clinical translation."

PACS2, a key resident protein at mitochondria-associated endoplasmic reticulum membranes (MAMs), regulates ER homeostasis under various pathological conditions. However, whether sepsis disrupts PACS2-dependent MAM integrity, thereby triggering ER dysfunction and muscle wasting, remains unexplored. We established a sepsis mouse model via cecal ligation and puncture (CLP) and assessed muscle function using compound muscle action potential (CMAP) recording and grip strength measurements. Muscle atrophy was evaluated by H&E staining and Western blotting. PACS2 expression was determined by Western blotting, immunohistochemistry and qRT-PCR. MAM integrity was assessed by immunofluorescence co-localization of IP3R and VDAC1, and ER-phagy (reticulophagy) activation was evaluated by transmission electron microscopy, Western blotting and fluorescence microscopy. To investigate the functional role of PACS2, adeno-associated virus (AAV)-mediated PACS2 overexpression was performed in mouse tibialis anterior muscle and gastrocnemius muscles, followed by RNA-sequencing analysis. The MAPK pathway proteins p-ERK, p-P38 and p-JNK levels were assessed by Western blotting, and the involvement of ERK-MAPK signalling was tested pharmacologically via intraperitoneal injection of the ERK inhibitor SCH772984. Septic mice developed progressive skeletal muscle atrophy (p\u2009<\u20090.001) and dysfunction (p\u2009<\u20090.01), accompanied by 56% reduction in PACS2 expression at 96\u2009h post-CLP (p\u2009<\u20090.01), 25% decrease in MAM integrity (p\u2009<\u20090.05) and subsequent activation of FAM134B-mediated ER-phagy (p\u2009<\u20090.01). AAV-mediated PACS2 overexpression significantly alleviated muscle atrophy by restoring MAM integrity by 28% (p\u2009<\u20090.01), reducing FAM134B expression by 43% (p\u2009<\u20090.01) and attenuating ER-phagy (p\u2009<\u20090.01). Co-immunoprecipitation revealed no detectable direct protein-protein interaction between PACS2 and FAM134B. Transcriptome sequencing and Western blotting analysis demonstrated that PACS2 overexpression specifically activated the ERK-MAPK signalling pathway (55% increase in p-ERK, p\u2009<\u20090.01) without affecting p-P38 or p-JNK levels (p>0.05), which suppressed FAM134B-mediated ER-phagy (p\u2009<\u20090.05) and ameliorated muscle atrophy (p\u2009<\u20090.05) by inhibiting nuclear translocation of TFEB (p\u2009<\u20090.01). Pharmacological ERK inhibition with SCH772984 abolished the protective effects of PACS2 by promoting TFEB nuclear translocation (p\u2009<\u20090.001) and TFEB-mediated FAM134B expression (p\u2009<\u20090.001). Our findings demonstrate that SIM is closely associated with disrupted MAM integrity. PACS2 plays a critical role in maintaining MAM structural integrity and regulating FAM134B-mediated ER-phagy through the ERK-MAPK-TFEB signalling axis, thereby providing novel mechanistic insights and potential therapeutic targets for SIM."

The mining of uranium and use of DU in modern weapons underly human exposure that disproportionally impacts military and tribal communities in the United States. Uranium's radiotoxic characteristics are understood, but its chemical hazards much less so. In zebrafish ( Danio rerio ) and human cell cultures we test the hypothesis that exposure to DU negatively impacts cellular function and development through disruption of mitochondrial metabolism. Using a novel shrapnel model with TEM/SEM+EDS, we showed uranium microparticles caused proximity-dependent mitochondrial disruption. In waterborne exposure paradigms, larval movement was reduced and hatching delayed as a result of reduced movement and not enzyme deficiencies in response to 18 ppb DU, below the MCL. Increased DNA damage accumulation was detected in exposed larva and cells. DNA-damage quantitative PCR of DU-exposed larvae showed increased damage in the ahr1 locus (nuclear gene) and decreased mitochondrial DNA (mtDNA) copy number, but mtDNA damage levels varied across experiments. Mitochondrial function was assessed using a resazurin-based assay in the presence and absence of antioxidants and showed diminished cytoplasmic reductive capacity. DU exposure alone did not enrich antioxidant gene expression, contrasting with arsenic exposure, a known ROS-inducer and Nrf2-activator. Sulforaphane (SFN), a potent Nrf2-activator, did not blunt the effects of DU exposure, despite activation of antioxidant response element (ARE) genes ( gstp and gss) , but did blunt the effects of arsenic exposure. The most enriched transcript in DU-exposed larvae coded for slingshot protein phosphatase ( ssh ), further exploration revealed ssh1b as the zebrafish-specific ortholog activated in response to DU, and inhibition using an identified SSH1 inhibitor, Sennoside A, partially rescued the metabolic and hatching defects observed. Our data points to a cytotoxic mechanism in which DU disrupts mitochondrial function through ssh1b enrichment that impairs normal mitophagy, leading to decreased cellular reductive potential independent of either ROS production or ARE-activation. Our results suggest that health impacts from DU exposure may be directly linked to impaired mitochondrial functions."

"abstract_text": "ID: 42197044\nTitle: Dietary Polyamine Intake Across Age Groups in Spain: A Comprehensive Assessment.\nAbstract: Polyamines, including putrescine (PU), spermidine (SPD), and spermine (SPM), are ubiquitous bioactive compounds essential for cell proliferation, genomic stability, autophagy, and the regulation of oxidative and inflammatory responses. Growing evidence, particularly for SPD, suggests that polyamine-rich diets may protect against age-related conditions such as cardiovascular disease, metabolic syndrome, and neurodegenerative disorders. As endogenous polyamine synthesis declines with age, dietary intake becomes increasingly important, especially in older adults. This study estimated each polyamine (PU, SPD and SPM) and total polyamine intake in the Spanish population using food consumption data from the Spanish Ministry of Agriculture, Fisheries and Food. Intakes were evaluated across four age groups, and major dietary sources were identified. Total polyamine intake increased with age, reaching 393 \u00b5mol/day in adults over 65 years. PU accounted for 49% of total intake, followed by SPD (29%) and SPM (22%). Plant-based foods were the primary contributors to SPD intake, particularly vegetables (36%), fruits (26%), and cereals (18%). PU intake was also predominantly plant-derived, mainly from fruits (58%) and vegetables (23%), whereas SPM intake was largely associated with meat products (59%). A theoretical Mediterranean diet model yielded a slightly higher total polyamine intake of 406.6 \u00b5mol/day and a substantially greater SPD intake than that observed in older adults (193.99 \u00b5mol/day versus 121.62 \u00b5mol/day). Overall, estimated polyamine intake in the Spanish population fell below the optimal level of 540 \u00b5mol/day proposed in the literature. These findings highlight the need for public health strategies promoting consumption of polyamine-rich foods, particularly vegetables, legumes, whole grains, and fruits, to support healthy aging and reduce the risk of age-related diseases."

This study demonstrates that fecal microbiota transplantation (FMT) confers protection against RILI through modulation of the gut-lung axis. In a total lung irradiation (TLI) mouse model, FMT significantly alleviated pulmonary histopathological injury, inflammatory responses, oxidative stress, and collagen deposition during fibrogenesis. Concurrently, FMT improved intestinal motility, enhanced mucosal barrier integrity, and restored TLI-induced dysbiosis in gut microbiota diversity and community structure. Metabolomic analysis revealed that TLI significantly disrupted the metabolism of unsaturated fatty acids and arachidonic acid (AA), whereas FMT partially restored these metabolic networks. Transcriptomic and ultrastructural analyses indicated that RILI suppressed endoplasmic reticulum (ER) protein processing and induced ER swelling, while FMT promoted protective ER-phagy and facilitated restoration of ER morphology. Integrated multi-omics analysis further identified the AA metabolism as a key component of FMT-mediated protection, with its alterations closely associated with pulmonary tissue repair. Further in vivo and in vitro experiments demonstrated that AA binds to and activates the nuclear receptor PPAR\u03b3, leading to transcriptional upregulation of FAM134B, promoting protective ER-phagy and ameliorating RILI. In summary, this study highlights the bidirectional gut-lung axis as a therapeutic target in RILI progression and intervention, and reveals that FMT confers protection through metabolic remodeling and activation of the PPAR\u03b3-FAM134B-mediated ER-phagy pathway, providing a mechanistic basis for potential clinical translation."

To our knowledge, no prior systematic review has synthesized evidence linking these metabolites to direct mitochondrial endpoints across all major metabolite classes. PubMed, Scopus, and Web of Science were systematically searched through March 2026 for studies examining direct mitochondrial endpoints in relation to ten classes of gut-derived metabolites. Gut-derived microbial metabolites exert diverse effects on mitochondrial function, ranging from bioenergetic enhancement to direct toxicity. After contextual evidence was excluded from the certainty assessment, four metabolite-mitochondrial outcome groupings had moderate certainty: butyrate, propionate, indoxyl sulfate, and lipopolysaccharide. Evidence for p-cresyl sulfate, H\u2082S, and urolithin A was rated low; evidence for the remaining metabolite classes was low or very low. Butyrate generally enhances mitochondrial biogenesis, ATP generation, and electron transport chain activity across multiple experimental models. Indoxyl sulfate generally impaired mitochondrial function, whereas p-cresyl sulfate produced concentration- and model-dependent effects. PGC-1\u03b1 emerges as a central regulatory node, integrating microbial metabolic signals to control mitochondrial biogenesis and oxidative metabolism. Many microbial metabolites demonstrate concentration-dependent biphasic effects. These findings support a mechanistic microbiome-mitochondrial framework in which diverse gut-derived molecules converge on a limited set of mitochondrial control nodes: electron transport chain activity, reactive oxygen species handling, biogenesis, and mitophagy. The evidence base is predominantly preclinical; these insights should be considered hypothesis-generating."

To address this question, we investigated a monogenic form of epilepsy (pyridoxine-dependent epilepsy) caused by aldehyde dehydrogenase 7 family member A1 (ALDH7A1) mutations. ALDH7A1 global knockout mice exhibited both seizure-associated and maladaptive affective behavioral phenotypes. However, seizure phenotypes were caused by ALDH7A1 deletion in hepatocytes whereas maladaptive affective behaviors were caused by ALDH7A1 deletion in astrocytes. Deletion in astrocytes disrupted astrocyte redox homeostasis, impairing regulation of extracellular ion concentrations and reducing neuronal activity in the prelimbic cortex. Sulforaphane, which activates the NRF2 antioxidant pathway, restored prelimbic neuronal activity and rescued maladaptive affective behaviors in ALDH7A1 knockout mice but did not prevent seizures. These studies implicate astrocyte redox homeostasis and prelimbic hypoactivity in maladaptive affective behavioral phenotypes in a congenital form of epilepsy, which are mechanistically and therapeutically dissociable from seizure pathophysiology."

Here, we examined the effects of two haloacetamides, 2,2-dichloroacetamide (DCAcAm) and 2,2-dibromoacetamide (DBAcAm), on mouse oocyte maturation and identified the underlying mechanisms of toxicity. Both compounds markedly impaired meiotic spindle assembly and compromised the function of multiple organelles, including mitochondria, the endoplasmic reticulum, and the Golgi apparatus, primarily through autophagy dysregulation at specific exposure concentrations, as evidenced by the observation that more than half of the oocytes failed to progress beyond the MII stage. Spermidine supplementation effectively restored autophagic activity and rescued the associated cellular defects, thereby improving both nuclear and cytoplasmic maturation in oocytes. Collectively, these findings demonstrate that spermidine alleviates toxicant-induced deterioration of oocyte quality by regulating autophagy and highlight its potential therapeutic value for reproductive protection and clinical application."

Here, we identify FAM134B/RETREG1 as a specific ER-phagy receptor mediating amyloid precursor protein (APP) degradation. FAM134B directly interacts with ER-localized wild-type and familial mutant APP via their C-terminal domains and recruits LC3 through its LC3-interacting region (LIR) to promote APP delivery to phagophores for lysosomal degradation. In AD, epigenetic silencing at the FAM134B promoter suppresses its transcription by limiting TFEB/TFE3 binding despite their nuclear enrichment. This transcriptional suppression impairs ER-phagy, leading to APP accumulation and exacerbated AD pathology. AAV-mediated hippocampal expression of wild-type, but not LIR-mutant, FAM134B in 5XFAD mice restores ER-phagy, enhances APP clearance, reduces A\u03b2 deposition, preserves synaptic and myelin integrity, and improves cognitive performance. These findings establish FAM134B downregulation as an upstream pathogenic event in AD, suggesting ER-phagy enhancement as a promising strategy to suppress A\u03b2 generation at its source."

Spermidine (SPD), a natural polyamine known to enhance autophagy and preserve cardiac function in aging and metabolic disorders, has not been systematically evaluated in the context of septic cardiomyopathy. To determine the therapeutic potential and mechanistic basis of SPD in septic cardiac dysfunction. Network pharmacology, RNA sequencing, a cecal ligation and puncture (CLP) mouse model, and multiple cellular assays were integrated to assess the protective actions of SPD. Mitochondrial function, mitophagy flux, and oxidative stress were evaluated using transmission electron microscopy (TEM), immunohistochemistry (IHC), Western blotting, structured illumination microscopy (SIM), mitochondrial membrane potential assays, oxygen consumption rate (OCR) analysis, and mitochondrial DNA (mtDNA) quantification. Transcriptomic clustering and pathway enrichment identified molecular targets, which were validated through siRNA-mediated gene silencing. SPD markedly attenuated SICM in vivo and in vitro by improving both mitochondrial quantity and quality. It restored sepsis-impaired mitophagy by upregulating LC3B and ATG7, promoting autophagosome maturation, and enhancing cellular ubiquitination. Transcriptomic profiling highlighted metallothionein-1 (MT1) as a key node in metal-ion response pathways. SPD activated the NRF2-MT1-SOD2 antioxidant axis, reduced mitochondrial reactive oxygen species (mtROS) under lipopolysaccharide (LPS) stimulation, and reversed sepsis-induced suppression of SOD2. MT1 knockdown abolished SPD-mediated SOD2 stabilization and mtROS clearance, confirming its essential role in SPD's cardioprotective effects. SPD mitigates SICM by orchestrating the restoration of mitochondrial quality control, normalization of mitophagic flux, and stabilization of cellular redox homeostasis. These findings support SPD as a promising therapeutic candidate for septic cardiomyopathy."

Here, using state-of-the-art super-resolution multi-SIM imaging, we reveal that stresses (prolonged starvation, cholesterol dyshomeostasis, and high-Ca2+ insults) trigger the expansion of sheet ER subdomains containing high levels of luminal Ca2+ in mammalian cells, which are subsequently degraded by ER-phagy. Autophagosome formation and sequestration of ER sheets require the concerted actions of FAM134B and lipidated LC3, whereas the autophagy proteins ATG14 and ATG9 are partially dispensable. Electron microscopy and cryo-electron tomography show that the membranes of autophagosomes enclosing high-Ca2+-containing ER sheets are directly remodeled from the ER. The ER-localized cation channels PIEZO1 and TRPV1 are enriched at and mediate Ca2+ transients from high-Ca2+-containing ER sheets, triggering liquid-liquid phase separation of the autophagosome-initiating FIP200 complex to initiate ER-phagy.

Current treatments offer limited efficacy, necessitating the development of innovative multitarget therapeutic strategies. Here, we present N3,N5-bis(2-(5-methoxy-1H-indol-3-yl)ethyl)-2,6-dimethyl-4-(2-nitrophenyl)pyridine-3,5-dicarboxamide (HCM-01), a novel compound developed to target multiple neurodegenerative pathways implicated in AD. In vitro assays included MTT-based cell viability analyses performed in two complementary experimental settings: primary neuronal cultures and astrocyte-based in vitro cell culture models exposed to glutamate. In primary hippocampal neuronal cultures, glutamate exposure induced a statistically significant reduction in cell viability compared with vehicle-treated controls, consistent with glutamate-induced excitotoxicity. Under these conditions, HCM-01 treatment resulted in a statistically significant improvement in neuronal viability, showing a greater protective effect compared with donepezil and memantine. In contrast, in astrocyte-based in vitro cultures, the applied glutamate concentration did not induce overt cytotoxicity, in line with the intrinsic neuroprotective and glutamate-buffering role of astrocytes. Accordingly, astrocytic experiments were designed to assess functional modulation of glutamate-handling mechanisms rather than cell survival. Western blot analysis in C8-D1A astrocytic cells demonstrated increased expression of excitatory amino acid transporter 2 (EAAT2) following HCM-01 treatment compared with control and reference drug-treated groups, suggesting modulation of astrocyte-mediated glutamate homeostasis. In parallel, redox analyses revealed that HCM-01 improved oxidative/antioxidative balance, as evidenced by increased total antioxidant capacity (TAC) and reduced total oxidant status (TOS), supporting an indirect antioxidant contribution to its functional effects. In vivo behavioral assessment of HCM-01 in a streptozotocin (STZ)-induced Alzheimer's model in female Sprague-Dawley rats demonstrated that administration of HCM-01 at doses of 50 mg/kg orally (oral, P.O. and intraperitoneal, I.P.) and 100 mg/kg (P.O.), significantly improved cognitive and memory functions in the passive avoidance (PA), Morris water maze (MWM), and locomotor activity tests. Moreover, histopathological and immunohistochemical analyses of different hippocampal regions revealed reduced neuronal damage, attenuation of tau pathology, antiamyloidogenic effect, and restoration of cholinergic function. Complementary in silico studies, including molecular docking, molecular dynamics simulations (MDS), and free energy calculations, suggested potential interactions of HCM-01 with the allosteric site of EAAT2. Taken together, these findings suggest that HCM-01 exerts neuroprotective effects against glutamate-induced excitotoxicity in primary hippocampal neurons while additionally modulating glutamatergic homeostasis and redox balance through functional mechanisms in astrocyte-based models, supporting its relevance as a multitarget preclinical candidate for early stage AD mechanisms."

These pathways converge to suppress BDNF/TrkB signaling (via miR-206 and impaired proBDNF cleavage), leading to deficits in synaptic protein synthesis (e.g., Arc) and trafficking (e.g., GluA1 endocytosis via STEP, impaired forward trafficking). Critically, these insults potentiate neuronal apoptosis through intrinsic (ROS/mitochondrial permeabilization, caspase-9/-3) and extrinsic (TNF-\u03b1/TNF-R1, caspase-8) pathways, executing irreversible synaptic loss via caspase-3 cleavage of PSD-95, spectrin, and cytoskeletal collapse. The structural consequences-dendritic simplification, reduced mature spine density, and PSD-95 nano-domain disorganization-manifest functionally as attenuated LTP, potentiated mGluR-LTD, and impaired STDP. This synaptic decay directly underpins cognitive impairments in pattern separation, contextual memory, and cognitive flexibility. Neuroinflammation (TLR4/NF-\u03baB) acts as a central amplifier, linking oxidative damage, excitotoxicity, and BDNF collapse to apoptotic synaptic deletion. Future research must address dose-dependency, subfield vulnerability, epigenetic regulation, and therapeutic strategies targeting TLR4, TrkB, mitochondrial antioxidants, and anti-apoptotic pathways."

Polyamines, including putrescine, spermidine, and spermine, are vital microbial-host metabolites that support intestinal cell growth, autophagy, immune modulation, and mucosal repair. With advancing age, both host-derived and microbiota-mediated polyamine production declines, contributing to intestinal dysfunction and heightened vulnerability to inflammation and age-related disorders. This review explores the diet-microbiota-polyamine axis as a key biological framework influencing intestinal aging. It aims to integrate evidence on how dietary components and functional foods shape gut microbial ecology and, in turn, regulate microbial polyamine biosynthetic pathways that impact intestinal health. The review highlights major microbial contributors to polyamine metabolism, particularly lactic acid bacteria, and outlines mechanistic pathways linking polyamines to epithelial regeneration, inflammatory control, and gut barrier maintenance. It further discusses how age-associated dysbiosis disrupts these interactions and evaluates nutritional and microbial-based strategies such as fermented foods, prebiotics, and probiotics that may enhance polyamine availability and restore gut homeostasis. From the standpoint of food microbiology and human physiology, this synthesis underscores the translational potential of targeting microbial polyamine production through diet-based interventions. This article presents a narrative review synthesizing experimental, animal, and emerging human evidence on microbial and dietary polyamines in intestinal aging. In conclusion, modulating the diet-microbiota-polyamine axis represents a promising strategy to promote healthy intestinal aging, meriting deeper mechanistic exploration and validation through clinical studies."

This study explores the interplay of endoplasmic reticulum stress (ERS), autophagy, and apoptosis in Cd-induced hepatotoxicity, focusing on whether ERS-driven autophagy protects against liver injury. Male SD rats (4\u202fweeks old, n\u202f=\u202f24) were acclimatized for 7\u202fdays and randomized into four groups receiving CdCl\u2082 at doses of 0, 0.5, 1, or 2\u202fmg/kg for 14 consecutive days. A second cohort (n\u202f=\u202f36) was similarly allocated to six groups: control, Cd, 4-PBA, Cd\u202f+\u202f4-PBA, CQ and Cd\u202f+\u202fCQ. All treatments were administered via daily intraperitoneal injection throughout the study. On day 14, blood and liver tissues were collected for analyses of liver function, hematological parameters, and histopathology. The expression of target factors was analyzed via qRT-PCR and Western blotting. Results indicate that Cd exposure causes liver injury and disordered hepatocyte morphology. ERS markers Grp78 and Caspase-12 and autophagy-related factors Beclin-1, Atg5, P62 and LC3 are upregulated at both mRNA and protein levels. The endoplasmic reticulum-phagy (ER-phagy) receptor FAM134B and the apoptosis effector cleaved Caspase3 are upregulated at the protein level. These findings indicate that Cd induces ERS, UPR activation, autophagy, reticulophagy, and apoptosis. The ERS inhibitor 4-PBA markedly attenuated Cd-induced hepatic injury. Compared with the Cd group, the Cd\u202f+\u202f4-PBA group showed decreased serum ALT and AST levels, as well as reduced RBC, WBC, MCH, and MCV counts. At the molecular level, mRNA and protein expression of ER stress markers Grp78, Caspase-12, PERK, eIF2\u03b1, ATF4, IRE1\u03b1, JNK, and ATF6 were all downregulated. Protein levels of the ER-phagy receptor FAM134B and the apoptosis effector cleaved Caspase-3 were also decreased. The autophagy inhibitor CQ aggravated such injury. Compared with the Cd group, the Cd\u202f+\u202fCQ group showed increased serum ALT and AST levels, as well as elevated RBC, MCH, and MCV counts. At the protein level, expression of the autophagy-related factors P62 and LC3, and the apoptosis effector cleaved Caspase-3 was significantly increased. These results show that Cd-induced ERS activates autophagy and reticulophagy mainly via the PERK, IRE1\u03b1, and ATF6 pathways, and this adaptive response clears autophagic substrates to alleviate hepatocyte damage."

MARCH6 and FAM134B expression levels were measured in glioma tissues. A comparative analysis was conducted on the correlation between clinical parameters and FAM134B expression in 46 glioma patients. FAM134B and MARCH6 were knocked down in glioma cells, followed by detection of cell viability and apoptosis, typical ER stress (ERS) markers (PERK, IRE1\u03b1, eIF2\u03b1, and CHOP), autophagy-related proteins (P62 and LC3B), and autophagosome cytoplasmic accumulation. A mouse glioma model was established for in vivo validation. MARCH6-FAM134B interaction, FAM134B ubiquitination levels, and protein stability were examined. FAM134B expression was high and MARCH6 expression was low in glioma tissues. MARCH6 induced FAM134B protein ubiquitination and degradation, reducing its stability in glioma cells. Knockdown of FAM134B reduced glioma cell survival, inhibited PERK, IRE1\u03b1, eIF2\u03b1, and CHOP expression, decreased LC3I to LC3II conversion, lowered LC3B fluorescence expression, and reduced the accumulation of autophagosomes with continuous ER structures in the cytoplasm, while enhancing apoptosis and P62 expression. This effect can be reversed by knocking down MARCH6. In vivo, FAM134B knockdown suppressed tumorigenesis in mice. MARCH6 exerts a repressive effect on ERS responses and ER-phagy in glioma cells by destabilizing FAM134B."

Endoplasmic reticulum (ER) stress and autophagy are two interconnected stress responses critical for maintaining cellular homeostasis. Berbamine (BBM) is an important member of bis-benzy lisoquinoline alkaloid with diverse biological activities. This study aimed to identify the molecular target of BBM against T-2 toxin-induced hepatotoxicity, focusing on autophagy-ER stress crosstalk. We systematically evaluated autophagy and ER stress in human HepaRG cells using immunoblotting, transmission electron microscopy and an autophagy reporter assay. T-2 toxin was found to concurrently activate PINK1/Parkin-mediated mitophagy and suppress Keap1-mediated FAM134B ubiquitination-dependent ER-phagy, thereby triggering ER stress. Integrated evidence from molecular dynamics and western blot demonstrated that BBM upregulated and stabilized BNIP3, blocking the VAMP8-SNAP29 interaction to inhibit T-2 toxin-induced autophagy and subsequent ER stress. Moreover, in vivo mouse experiments demonstrated that 30\u202fmg/kg BBM significantly alleviated T-2 toxin-induced liver injury by suppressing both autophagic flux and ER stress; BBM significantly reduced serum levels of liver enzymes, ALT, and AST. Collectively, our findings elucidate a novel mechanism wherein T-2 toxin-induced mitophagy inhibits ER-phagy to drive ER stress-mediated liver injury and highlight the therapeutic potential of BBM in alleviating T-2 toxin-induced liver injury."

This study investigates the neuroprotective potential of Sulforaphane (SFN) in ameliorating ethidium bromide (EBRM)-induced MS-like pathology in Wistar rats. The efficacy of SFN at two doses (SFN1.5 and SFN3) was compared to FDA-approved Nrf2 activator drugs, omaveloxolone (OMV15) and dimethyl fumarate (DIMF50). EBRM administration caused neurobehavioral deficits, demyelination, oxidative stress, axonal degeneration, and inflammation. It disrupted key cellular pathways, including Nrf2/HO-1/SIRT-1, JAK/STAT-3/mTOR, and BACE-1/Gamma-secretase/MAPT, as well as caused neurotransmitter imbalances. SFN3 demonstrated significant improvement in motor function, cognitive performance, neurotransmitter levels antioxidant enzymes and alleviated neuroinflammation by modulating inflammatory cytokines. Molecular analyses showed that SFN3 increased Nrf2/HO-1/SIRT-1 levels while decreased pro-inflammatory and neurodegenerative markers such as STAT-3, mTOR, and BACE-1 levels. Gross pathological, Histopathological, and LFB studies indicated reduced demyelination and liver damage. SFN3 also demonstrated favourable systemic safety compared to OMV15. While DIMF50 showed the highest overall efficacy, SFN3 showed consistent modulation of pathological markers, neuroprotective effects, and safety profile. These findings suggest that SFN3 may have therapeutic potential for further translational research in MS. Future studies should validate its clinical relevance and explore combinatorial therapies with existing MS treatments to enhance therapeutic outcomes."

Alginate oligosaccharide (AOS), a marine-derived bioactive polysaccharide, exhibits prebiotic, anti-inflammatory and antioxidant properties that are effective against various inflammatory diseases. In this study, a mouse model of SAP was established by intraperitoneal injection of cerulein (100 \u03bcg/kg) and lipopolysaccharide (5 mg/kg), and the mice were pretreated with AOS (200 mg/kg) by gavage for 4 consecutive weeks to explore the potential protective efficacy and underlying mechanisms. The results shown that AOS attenuated the severity of SAP, as evidenced by reduced serum amylase and lipase levels, as well as alleviated histopathological injury in both pancreatic and ileal tissues. AOS suppressed the overproduction of pro-inflammatory cytokines (IL-1\u03b2, IL-6, TNF-\u03b1) in serum, pancreas, and ileum at protein or mRNA levels. Moreover, AOS effectively diminished pancreatic and ileal inflammatory infiltration and oxidative stress in SAP mice, accompanied by inhibited the TLR4/MyD88/NF-\u03baB pathway and activated the Nrf2/HO-1 antioxidant axis. Furthermore, AOS restored intestinal barrier integrity, as manifested by upregulated expression of tight junction proteins (claudin-1, occludin, ZO-1), reduced serum diamine oxidase, and decreased bacterial translocation from the gut to the pancreas. It was revealed by 16S rRNA sequencing that AOS ameliorated SAP-induced gut dysbiosis by restoring microbial diversity, normalizing the Firmicutes/Bacteroidetes ratio, enriching beneficial genera (Lactobacillus, Blautia), and enhancing cecal short-chain fatty acid (acetic, propionic, butyric acid) production. Collectively, our findings demonstrate that AOS exerts comprehensive protective effects against SAP through suppression of inflammatory signaling and oxidative stress, as well as restoring gut homeostasis. These results suggest that AOS may serve as a promising prebiotic-based nutritional strategy for the management of SAP."

Here, we found that SS-31 supplementation efficaciously improved oocyte maturation and early embryonic development from aged mice. Specifically, SS-31 remarkably restored the normal spindle/chromosome structure, fertilization ability, mitochondrial distribution, \u0394\u03a8m and mitophagy in aged oocytes. In contrast, SS-31 reduced oocyte aneuploidy, ROS accumulation and DNA damage. Mechanistically, single-cell transcriptome analysis reveals that SS-31 increased the maternal mRNA degradation, and the levels of genes associated with mitochondrial function and mitophagy in aged oocytes, such as Pink1, Rps27a, Tomm7 and Map1lc3b. In addition, SS-31 suppressed chromatin organization, histone modification and chromatin remodeling pathways. Moreover, we applied the single-cell untargeted metabolomics to identify that SS-31 increased the levels of spermidine and GSH, which were critical metabolites to protect oocytes against aging. Our data reveal that the beneficial effect of SS-31 on oocyte quality from advanced age is mainly mediated by restoration of mitochondrial function, mitophagy and anti-aging metabolites.

Here, we identify ER-phagy as a previously unrecognized adaptive response to ISOXUS, an isoxazole derivative of usnic acid with selective anticancer activity. ISOXUS, a mitochondrial respiratory complex II inhibitor, induces bioenergetic collapse, reactive oxygen species accumulation, and extensive ER-derived vacuolization. Using integrated transcriptomic and metabolomic analyses, we demonstrate that ISOXUS selectively triggers ER-phagy in mitochondria-dependent MCF-7 breast cancer cells, but not in more glycolytic triple-negative MDA-MB-231 cells, revealing a cell-type-specific stress adaptation program. ER-phagy induction is associated with upregulation of the ER-phagy receptor FAM134B and depends on ER stress signalling, as pharmacological ER stress inhibition suppresses this process. Multi-omics profiling uncovers coordinated repression of mitochondrial gene expression together with activation of ER-centered metabolic pathways, including amino acid metabolism, the tricarboxylic acid cycle, and one-carbon folate metabolism. Notably, we also identify UFMylation-related genes (CDK5RAP3, DDRGK1) as novel candidates involved in ER-phagy induced by ISOXUS. Moreover, mitochondrial inhibitors, rotenone and oligomycin, unexpectedly promote, while antioxidant a-tocopherol blocks ISOXUS-induced ER-phagy, and all compounds partially improve cell viability under ISOXUS treatment, implicating ROS-driven ER-phagy as a cytoprotective mechanism. Integrated analyses further reveal activation of the integrated stress response (ISR), dominated by the PERK-ATF4 axis, driving glutamine-dependent metabolic reprogramming and suppression of apoptosis-related pathways. The late-stage autophagy inhibition lowered the glutathione synthesis after ISOXUS treatment. Collectively, our findings uncover a previously unappreciated mitochondria-ER-ISR axis that governs metabolic adaptation to ISOXUS and identifies ER-phagy as a potential therapeutic vulnerability in breast cancer."

Spermidine (SPD), a natural polyamine known to enhance autophagy and preserve cardiac function in aging and metabolic disorders, has not been systematically evaluated in the context of septic cardiomyopathy. To determine the therapeutic potential and mechanistic basis of SPD in septic cardiac dysfunction. Network pharmacology, RNA sequencing, a cecal ligation and puncture (CLP) mouse model, and multiple cellular assays were integrated to assess the protective actions of SPD. Mitochondrial function, mitophagy flux, and oxidative stress were evaluated using transmission electron microscopy (TEM), immunohistochemistry (IHC), Western blotting, structured illumination microscopy (SIM), mitochondrial membrane potential assays, oxygen consumption rate (OCR) analysis, and mitochondrial DNA (mtDNA) quantification. Transcriptomic clustering and pathway enrichment identified molecular targets, which were validated through siRNA-mediated gene silencing. SPD markedly attenuated SICM in vivo and in vitro by improving both mitochondrial quantity and quality. It restored sepsis-impaired mitophagy by upregulating LC3B and ATG7, promoting autophagosome maturation, and enhancing cellular ubiquitination. Transcriptomic profiling highlighted metallothionein-1 (MT1) as a key node in metal-ion response pathways. SPD activated the NRF2-MT1-SOD2 antioxidant axis, reduced mitochondrial reactive oxygen species (mtROS) under lipopolysaccharide (LPS) stimulation, and reversed sepsis-induced suppression of SOD2. MT1 knockdown abolished SPD-mediated SOD2 stabilization and mtROS clearance, confirming its essential role in SPD's cardioprotective effects. SPD mitigates SICM by orchestrating the restoration of mitochondrial quality control, normalization of mitophagic flux, and stabilization of cellular redox homeostasis. These findings support SPD as a promising therapeutic candidate for septic cardiomyopathy."

As an important carbohydrate, starch directly affects the homeostasis of glucose and lipid metabolism due to its digestion characteristics. Resistant starch (RS) with unique anti-digestive properties and prebiotic functions has become the current hotspot in dietary nutrition research for improving glucose and lipid metabolism disorders. This review summarizes the digestive characteristics of starch and the comprehensive effects of RS and its mechanisms for ameliorating metabolic diseases. Diets with high RS content not only optimize glucose homeostasis by delaying glucose release, the undigested fractions entering the colon also drive the metabolic regulatory network of the gut microbiota-gut-brain axis by activating the AMPK/ACC pathway to reduce fat accumulation, enhancing intestinal barrier function mediated by short-chain fatty acids (SCFAs), and promoting GLP-1/PYY neural signal transduction. These insights facilitate the design of new healthy foods and inspire new strategies for optimizing dietary nutrition and regulating glucose and lipid metabolism disorders caused by high-carbohydrate diets. \u4ee3\u8c22\u6027\u75be\u75c5\u5982\u80a5\u80d6\u3001\u7cd6\u5c3f\u75c5\u3001\u5fc3\u8840\u7ba1\u75be\u75c5\u7684\u5168\u7403\u6d41\u884c\u4e0e\u8425\u517b\u8fc7\u5269\u53ca\u996e\u98df\u6a21\u5f0f\u5931\u8861\u5bc6\u5207\u76f8\u5173\u3002\u6dc0\u7c89\u4f5c\u4e3a\u4eba\u7c7b\u4e3b\u8981\u80fd\u91cf\u6765\u6e90\u7684\u78b3\u6c34\u5316\u5408\u7269\uff0c\u5176\u6d88\u5316\u7279\u6027\u76f4\u63a5\u5f71\u54cd\u7cd6\u8102\u4ee3\u8c22\u7a33\u6001\u3002\u6297\u6d88\u5316\u6027\u6dc0\u7c89\uff08RS\uff09\u56e0\u5176\u72ec\u7279\u7684\u6297\u6d88\u5316\u7279\u6027\u4e0e\u76ca\u751f\u5143\u529f\u80fd\uff0c\u6210\u4e3a\u5f53\u524d\u6539\u5584\u7cd6\u8102\u4ee3\u8c22\u7d0a\u4e71\u7684\u81b3\u98df\u8425\u517b\u7814\u7a76\u7684\u70ed\u70b9\u3002\u672c\u6587\u7efc\u8ff0\u4e86\u6dc0\u7c89\u6d88\u5316\u7279\u6027\u4ee5\u53caRS\u6539\u5584\u4ee3\u8c22\u6027\u75be\u75c5\u7684\u7efc\u5408\u4f5c\u7528\u53ca\u76f8\u5173\u673a\u5236\u3002\u9ad8RS\u7684\u81b3\u98df\u4e0d\u4ec5\u901a\u8fc7\u5ef6\u7f13\u8461\u8404\u7cd6\u91ca\u653e\u4f18\u5316\u8840\u7cd6\u7a33\u6001\uff0c\u800c\u4e14\u672a\u6d88\u5316\u7684\u90e8\u5206\u8fdb\u5165\u7ed3\u80a0\u901a\u8fc7\u9a71\u52a8\u80a0\u9053\u83cc\u7fa4-\u80a0-\u8111\u8f74\u4ee3\u8c22\u8c03\u63a7\u7f51\u7edc\uff0c\u5176\u4e2d\u5305\u62ec\u6fc0\u6d3b\u817a\u82f7\u9178\u6d3b\u5316\u86cb\u767d\u6fc0\u9176/\u4e59\u9170\u8f85\u9176A\u7fa7\u5316\u9176\uff08AMPK/ACC\uff09\u901a\u8def\u51cf\u5c11\u8102\u80aa\u84c4\u79ef\u3001\u63d0\u5347\u77ed\u94fe\u8102\u80aa\u9178\uff08SCFAs\uff09\u4ecb\u5bfc\u7684\u80a0\u5c4f\u969c\u529f\u80fd\u4e0e\u80f0\u9ad8\u8840\u7cd6\u7d20\u6837\u80bd-1/\u80bdYY\uff08GLP-1/PYY\uff09\u795e\u7ecf\u4fe1\u53f7\u4f20\u5bfc\u3002\u8fd9\u4e0d\u4ec5\u5c06\u4e3a\u65b0\u578b\u5065\u5eb7\u98df\u54c1\u8bbe\u8ba1\u63d0\u4f9b\u7814\u7a76\u57fa\u7840\uff0c\u4e5f\u4e3a\u4f18\u5316\u81b3\u98df\u8425\u517b\uff0c\u8c03\u63a7\u9ad8\u78b3\u6c34\u996e\u98df\u5f15\u8d77\u7684\u7cd6\u8102\u4ee3\u8c22\u7d0a\u4e71\u63d0\u4f9b\u4e86\u65b0\u7684\u7814\u7a76\u601d\u8def\u3002."

To address this question, we investigated a monogenic form of epilepsy (pyridoxine-dependent epilepsy) caused by aldehyde dehydrogenase 7 family member A1 (ALDH7A1) mutations. ALDH7A1 global knockout mice exhibited both seizure-associated and maladaptive affective behavioral phenotypes. However, seizure phenotypes were caused by ALDH7A1 deletion in hepatocytes whereas maladaptive affective behaviors were caused by ALDH7A1 deletion in astrocytes. Deletion in astrocytes disrupted astrocyte redox homeostasis, impairing regulation of extracellular ion concentrations and reducing neuronal activity in the prelimbic cortex. Sulforaphane, which activates the NRF2 antioxidant pathway, restored prelimbic neuronal activity and rescued maladaptive affective behaviors in ALDH7A1 knockout mice but did not prevent seizures. These studies implicate astrocyte redox homeostasis and prelimbic hypoactivity in maladaptive affective behavioral phenotypes in a congenital form of epilepsy, which are mechanistically and therapeutically dissociable from seizure pathophysiology."

Although PFOS exposure causes significant bioaccumulation and potential myelotoxicity, its specific impact on the chondrogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) remains to be elucidated. In this study, we established a murine model of PFOS exposure to isolate primary BMSCs and investigated this issue through in vitro differentiation assays, cellular senescence evaluations, and an in vivo subcutaneous implantation model using gelatin methacryloyl (GelMA) hydrogel scaffolds. Our results demonstrated that PFOS exposure triggered intracellular reactive oxygen species (ROS) accumulation and induced a senescent phenotype in BMSCs, characterized by restricted cellular proliferation and the release of senescence-associated secretory phenotype (SASP) factors, thereby markedly suppressing their chondrogenic capacity. Mechanistically, the inhibition of the Nrf2 signaling pathway by PFOS was identified as the principal driver of this process. Furthermore, both in vitro and in vivo assays confirmed that pharmacological activation using the Nrf2 agonist sulforaphane (SFN) effectively mitigated the senescent phenotype and restored the chondrogenic potential of PFOS-exposed BMSCs. Altogether, these findings elucidate the specific mechanisms of PFOS-induced stem cell toxicity and offer a potential strategy to overcome the resulting limitations in BMSC-based cartilage regeneration."

PACS2, a key resident protein at mitochondria-associated endoplasmic reticulum membranes (MAMs), regulates ER homeostasis under various pathological conditions. However, whether sepsis disrupts PACS2-dependent MAM integrity, thereby triggering ER dysfunction and muscle wasting, remains unexplored. We established a sepsis mouse model via cecal ligation and puncture (CLP) and assessed muscle function using compound muscle action potential (CMAP) recording and grip strength measurements. Muscle atrophy was evaluated by H&E staining and Western blotting. PACS2 expression was determined by Western blotting, immunohistochemistry and qRT-PCR. MAM integrity was assessed by immunofluorescence co-localization of IP3R and VDAC1, and ER-phagy (reticulophagy) activation was evaluated by transmission electron microscopy, Western blotting and fluorescence microscopy. To investigate the functional role of PACS2, adeno-associated virus (AAV)-mediated PACS2 overexpression was performed in mouse tibialis anterior muscle and gastrocnemius muscles, followed by RNA-sequencing analysis. The MAPK pathway proteins p-ERK, p-P38 and p-JNK levels were assessed by Western blotting, and the involvement of ERK-MAPK signalling was tested pharmacologically via intraperitoneal injection of the ERK inhibitor SCH772984. Septic mice developed progressive skeletal muscle atrophy (p\u2009<\u20090.001) and dysfunction (p\u2009<\u20090.01), accompanied by 56% reduction in PACS2 expression at 96\u2009h post-CLP (p\u2009<\u20090.01), 25% decrease in MAM integrity (p\u2009<\u20090.05) and subsequent activation of FAM134B-mediated ER-phagy (p\u2009<\u20090.01). AAV-mediated PACS2 overexpression significantly alleviated muscle atrophy by restoring MAM integrity by 28% (p\u2009<\u20090.01), reducing FAM134B expression by 43% (p\u2009<\u20090.01) and attenuating ER-phagy (p\u2009<\u20090.01). Co-immunoprecipitation revealed no detectable direct protein-protein interaction between PACS2 and FAM134B. Transcriptome sequencing and Western blotting analysis demonstrated that PACS2 overexpression specifically activated the ERK-MAPK signalling pathway (55% increase in p-ERK, p\u2009<\u20090.01) without affecting p-P38 or p-JNK levels (p>0.05), which suppressed FAM134B-mediated ER-phagy (p\u2009<\u20090.05) and ameliorated muscle atrophy (p\u2009<\u20090.05) by inhibiting nuclear translocation of TFEB (p\u2009<\u20090.01).

The mining of uranium and use of DU in modern weapons underly human exposure that disproportionally impacts military and tribal communities in the United States. Uranium's radiotoxic characteristics are understood, but its chemical hazards much less so. In zebrafish ( Danio rerio ) and human cell cultures we test the hypothesis that exposure to DU negatively impacts cellular function and development through disruption of mitochondrial metabolism. Using a novel shrapnel model with TEM/SEM+EDS, we showed uranium microparticles caused proximity-dependent mitochondrial disruption. In waterborne exposure paradigms, larval movement was reduced and hatching delayed as a result of reduced movement and not enzyme deficiencies in response to 18 ppb DU, below the MCL. Increased DNA damage accumulation was detected in exposed larva and cells. DNA-damage quantitative PCR of DU-exposed larvae showed increased damage in the ahr1 locus (nuclear gene) and decreased mitochondrial DNA (mtDNA) copy number, but mtDNA damage levels varied across experiments. Mitochondrial function was assessed using a resazurin-based assay in the presence and absence of antioxidants and showed diminished cytoplasmic reductive capacity. DU exposure alone did not enrich antioxidant gene expression, contrasting with arsenic exposure, a known ROS-inducer and Nrf2-activator. Sulforaphane (SFN), a potent Nrf2-activator, did not blunt the effects of DU exposure, despite activation of antioxidant response element (ARE) genes ( gstp and gss) , but did blunt the effects of arsenic exposure. The most enriched transcript in DU-exposed larvae coded for slingshot protein phosphatase ( ssh ), further exploration revealed ssh1b as the zebrafish-specific ortholog activated in response to DU, and inhibition using an identified SSH1 inhibitor, Sennoside A, partially rescued the metabolic and hatching defects observed. Our data points to a cytotoxic mechanism in which DU disrupts mitochondrial function through ssh1b enrichment that impairs normal mitophagy, leading to decreased cellular reductive potential independent of either ROS production or ARE-activation. Our results suggest that health impacts from DU exposure may be directly linked to impaired mitochondrial functions."

Here, we investigated whether the polyamine biosynthetic enzyme S-adenosylmethionine decarboxylase 1 (AMD1) regulates tubular senescence and repair outcomes after AKI and elucidated the underlying mechanism. AMD1 dynamics were examined in an ischemia-reperfusion injury model using male C57BL/6J mice by immunofluorescence. AAV-mediated Ksp promoter-driven tubule-specific Amd1 conditional knockdown male mice (Amd1 cKD) were used to assess renal injury, cell-cycle status, senescence, and remodeling, and exogenous spermidine was administered for rescue. DNA damage signaling and p53/p21 activation were evaluated by immunostaining, Western blotting, and EdU incorporation assays. AMD1 was predominantly expressed in the tubular epithelium, with prominent dynamic induction in proximal tubules early after IRI, but declined to baseline levels during the late phase, representing a relative metabolic insufficiency that correlated inversely with fibrosis. Compared with wild-type controls, Amd1 cKD mice exhibited aggravated tubular injury, an over two-fold increase in SA-\u03b2-gal-positive areas, elevated p21, and reduced Ki67+ proliferation. Conversely, spermidine supplementation improved renal function, reduced fibrosis by 75.3%, and decreased senescent regions by 74%. Mechanistically, AMD1 deficiency increased \u03b3H2AX-marked DNA damage and activated the p53/p21 checkpoint, whereas spermidine attenuated this response and restored DNA synthesis capacity. Collectively, tubular AMD1 acts as a metabolic checkpoint that preserves polyamine homeostasis to restrain p53/p21-dependent senescence, promote adaptive repair after AKI, and spermidine supplementation represents a potential strategy to mitigate maladaptive AKI-to-CKD progression."

Growing evidence shows that metabolites generated along the gut-brain axis regulate neuroinflammation. In this study, we demonstrate that oral administration of sodium butyrate (NaB) (300 or 600\u2009mg/kg/day) for 28 days lowered mortality and lessened neuropathological signs in mice infected with SS2 (SC19 strain). Butyrate prophylaxis was associated with lower bacterial loads in the blood and brain tissue, preserved expression of tight junction proteins (ZO-1, Claudin-5, and Occludin) in the brain, and maintained blood-brain barrier (BBB) integrity and permeability. 16S rRNA sequencing analysis revealed that SC19 infection significantly diminished the diversity and richness of the gut microbiota, notably depleting key short-chain fatty acid (SCFA)-producing bacterial taxa. Butyrate intervention restored microbial homeostasis and enriched SCFA-producing communities. Mechanistically, butyrate was associated with upregulated expression of nuclear factor erythroid 2-related factor 2 (Nrf2) and its downstream antioxidant effectors (heme oxygenase 1 [HO-1] and NQO1), while inhibiting phosphorylation of NF-\u03baB p65 and the secretion of proinflammatory cytokines (interleukin-1\u03b2 [IL-1\u03b2], interleukin-6 [IL-6], and tumor necrosis factor-\u03b1 [TNF-\u03b1]) in human cortical microvessels endothelial cells/D3 (hCMEC/D3) cells.

Our findings highlight the prophylactic potential of modulating the gut-brain axis as a novel strategy to mitigate central nervous system (CNS) infections associated with foodborne pathogens."

While fetal lung signals are known to help initiate labor, the role of the placenta has remained unclear. Here we show that in steroid receptor coactivator (Src)-1 and -2 double-knockout mice, reduced placental amine oxidase, copper-containing 1 (Aoc1) leads to increased spermidine levels. In trophoblast cells, spermidine induces autophagy via hypusination of eukaryotic translation initiation factor 5\u2009A (EIF5A), reducing estrogen and prostaglandin production. Estrogen reciprocally increases Aoc1 expression via estrogen receptor-\u03b1 (ER\u03b1) in concert with SRC-1/2, forming a feedback loop maintaining placental autophagy homeostasis. AOC1 levels are elevated in preterm labor placentas from both mice and humans. Placenta-specific Aoc1 knockout dramatically delays labor by increasing trophoblast autophagy. Importantly, spermidine supplementation rescues inflammation-induced preterm labor in mice. Our findings reveal that placental AOC1-spermidine-EIF5A-autophagy axis is essential for parturition timing and offer a potential therapeutic strategy for preterm birth."

Downregulation of EAAT2 results in glutamate accumulation, N-Methyl-D-Aspartate (NMDA) receptor overactivation, and neuronal injury. Crocin (Cr), a carotenoid compound extracted from saffron (Crocus sativus), exhibits potent antioxidant and neuroprotective properties, particularly in experimental models of neurodegeneration. Forty-eight adult male rats were divided into six groups: control (saline), crocin (50\u00a0mg/kg), scopolamine (3\u00a0mg/kg for 7 days), scopolamine followed by memantine (M) (20\u00a0mg/kg), scopolamine followed by crocin, and scopolamine followed by both memantine and crocin. This study aimed to evaluate the therapeutic potential of crocin, alone and in combination with memantine, in a scopolamine-induced rat model of Alzheimer's disease, with a focus on EAAT2 modulation. Scopolamine administration significantly elevated glutamate, NMDAR and p-tau levels while reducing p-Akt, GABA and EAAT2 levels, accompanied by marked hippocampal neurodegeneration. In contrast, crocin treatment, either alone or in combination with memantine, restored neurotransmitter balance, downregulated NMDAR, upregulated EAAT2, increased p-Akt expression level and reduced tau phosphorylation.

Spermidine has been shown to counteract immunosenescence and induce autophagy in preclinical models, and its levels decline with age in humans. We conducted a double-blind, randomised, placebo-controlled pilot study in 40 adults over 65\u2009years of age following their third SARS-CoV-2 vaccine dose to assess the safety of Spermidine and its effects on vaccine-induced immunity. Daily oral supplementation (6\u2009mg, 13\u2009weeks) was well-tolerated. Vaccine non-responsiveness was common, and non-responders exhibited a distinct immune-senescence signature marked by elevated p16, mTOR signalling, and \u03b3-H2AX+ DNA damage in lymphocytes. Spermidine reversed these features and significantly enhanced spike-specific IgG secretion, memory B cell recall responses and neutralising antibody activity, specifically in non-responders. Single-cell RNA-seq after treatment revealed increased expression of TFEB targets and autophagy-related genes in B cells, in line with elevated autophagic flux. These findings suggest that targeting immune cell senescence with Spermidine may improve vaccine responsiveness in older adults and highlight immune-senescence markers as potential predictors of vaccine failure in ageing populations."

Spermidine (SPD) is known to ameliorate age-related cognitive decline, and the gut microbiota is an important source of SPD. Clostridium butyricum (C. butyricum), a probiotic, can alleviate cognitive decline in individuals with various neurodegenerative diseases, and C. butyricum might generate SPD. However, the role of C. butyricum in natural brain aging and the efficacy of C. butyricum and the metabolite SPD in ameliorating age-related cognitive decline remain unclear. Here, we investigated the effects of C. butyricum and its metabolite SPD on cognitive decline during natural brain aging and the mechanisms underlying these effects. Aged rats\u00a0(aged 17 months, n\u202f=\u202f12 per group) were randomly divided into normal saline (NS), C. butyricum (1\u202f\u00d7108\u223c109 CFU/ml, by gavage for two months) and SPD (6.5\u202fmg/kg/d, by gavage for one month) groups.

Furthermore, treatment with C. butyricum and SPD enhanced intestinal barrier function and decreased serum proinflammatory factor levels and brain tissue damage due to oxidative stress. There were no significant differences in relevant indicators between the C. butyricum and SPD groups. In conclusion, C. butyricum and its metabolite SPD may delay the cognitive decline caused by normal brain aging by reducing oxidative stress and inflammation."

The nuclear factor erythroid 2-related factor 2 (Nrf2) pathway plays a central role in regulating cellular antioxidant defences against UV-induced damage. This scoping review aims to evaluate the potential role of sulforaphane (SFN), a known Nrf2 inducer, in protecting against UV-induced skin damage and photocarcinogenesis. Methods: A literature search was conducted in PubMed and Scopus from inception to 27 January 2026, to identify original experimental studies investigating SFN, glucoraphanin, or broccoli sprout extracts in the context of UV-induced skin damage. Eligible studies included in vitro, ex vivo, in vivo, and human models assessing outcomes related to oxidative stress, inflammation, molecular signalling pathways, and tumour development. Following screening and eligibility assessment, twelve studies were included in the qualitative synthesis. Results: The included studies suggest that SFN exerts photoprotective effects across multiple experimental models. In murine studies, SFN and SFN-rich extracts were associated with a reduction in tumour incidence, multiplicity, and volume following UV exposure. In human studies, topical SFN application reduced UV-induced erythema and induced cytoprotective enzyme expression, although clinical evidence remains limited. Mechanistically, SFN consistently activated the Nrf2 pathway, leading to increased expression of antioxidant and phase II detoxifying enzymes, and was associated with modulation of inflammatory responses and inhibition of MAPK/AP-1 signalling. Emerging evidence also indicates potential effects on UV-induced metabolic and epigenetic alterations. Conclusions: Current evidence supports a potential role for sulforaphane in mitigating UV-induced skin damage through activation of endogenous defence pathways. However, the available data are predominantly preclinical, and further well-designed clinical studies are needed to clarify its efficacy and translational relevance in humans."

This narrative review synthesizes preclinical and early clinical evidence on the mechanisms and therapeutic applicability of SFN in ICU-acquired weakness, diabetic myopathy, sarcopenia, and exercise-induced muscle damage. SFN modulates skeletal muscle pathophysiology through four interconnected axes: regulation of protein homeostasis via mTOR-associated signaling and suppression of ubiquitin-proteasome-mediated catabolism; upregulation of oxidative stress defenses through Nrf2-driven antioxidant enzyme induction; attenuation of inflammatory networks via NF-\u03baB inhibition and promotion of M2 macrophage polarization; and metabolic reprogramming through AMPK-mediated mitochondrial biogenesis and enhanced insulin sensitivity. Preclinical data suggest preliminary protective effects on respiratory and locomotor muscle; however, clinical translation remains uncertain. Several randomized controlled trials have failed to demonstrate significant effects on Nrf2 target genes or metabolic stress biomarkers, and bioavailability varies markedly across formulations and individuals. Heterogeneous responses across muscle fiber types, an undefined therapeutic window, and interindividual variability in gut microbiota-mediated conversion further complicate clinical application. To address these challenges, we propose a conceptual \"Sulforaphane Precision Medicine Framework\" integrating molecular biomarkers, gut microbiome profiling, and dynamic delivery systems to guide personalized intervention. While SFN shows promise as an adjunctive therapy, standardized formulations, refined patient stratification, and rigorous phase III trials are essential before routine clinical adoption can be recommended."

Here, we examined the effects of two haloacetamides, 2,2-dichloroacetamide (DCAcAm) and 2,2-dibromoacetamide (DBAcAm), on mouse oocyte maturation and identified the underlying mechanisms of toxicity. Both compounds markedly impaired meiotic spindle assembly and compromised the function of multiple organelles, including mitochondria, the endoplasmic reticulum, and the Golgi apparatus, primarily through autophagy dysregulation at specific exposure concentrations, as evidenced by the observation that more than half of the oocytes failed to progress beyond the MII stage. Spermidine supplementation effectively restored autophagic activity and rescued the associated cellular defects, thereby improving both nuclear and cytoplasmic maturation in oocytes. Collectively, these findings demonstrate that spermidine alleviates toxicant-induced deterioration of oocyte quality by regulating autophagy and highlight its potential therapeutic value for reproductive protection and clinical application."

Here, we identify the vitamin D receptor (Vdr) as a key anti-aging transcription factor whose expression in granulosa cells (GCs) declines with age. Using GCs-specific Vdr knockout (cVKO) mice and a Vdr-knockout (VKO) human granulosa-like cell line, we demonstrate that loss of Vdr triggers GCs aging and disrupts ovarian function. Integrated transcriptomic and metabolomic analyses from VKO and WT cells revealed that Vdr loss downregulates the de novo spermidine (SPD) biosynthesis by directly suppressing the transcription of ornithine decarboxylase (ODC1). This led to SPD depletion, which in turn inhibited DNA methyltransferase (DNMTs) activity, resulting in hypomethylation of the p53 promoter and activation of the p53/p21 pathway. Crucially, supplementation with either SPD or its upstream methyl donor S-adenosylmethionine (SAM) rescued cVKO and VKO cell aging, improved hormonal profiles and promoted follicular development in cVKO mice. Furthermore, both supplements effectively delayed ovarian aging and improved fertility in naturally aged mice. Our study unveils the Vdr-spermidine-DNMTs axis as a fundamental mechanism safeguarding against ovarian aging, highlighting SPD and SAM as promising therapeutic agents for age-related female infertility."

ZEN exposure induces endoplasmic reticulum (ER) stress, oxidative stress, and autophagy activation. However, the involvement of inositol-requiring enzyme 1 (IRE1)-mediated ER-phagy in ZEN-induced ER stress and embryonic competence during in vitro culture (IVC) remains unclear. Porcine embryos were cultured with 2.5, 5, and 10\u202f\u03bcM ZEN for two days after in vitro fertilization (IVF) to assess blastocyst development. ZEN exposure caused a significant dose-dependent decrease in blastocyst formation, expanded blastocysts, and total cell number (p\u202f<\u202f0.05).

Growing evidence, particularly for SPD, suggests that polyamine-rich diets may protect against age-related conditions such as cardiovascular disease, metabolic syndrome, and neurodegenerative disorders. As endogenous polyamine synthesis declines with age, dietary intake becomes increasingly important, especially in older adults. This study estimated each polyamine (PU, SPD and SPM) and total polyamine intake in the Spanish population using food consumption data from the Spanish Ministry of Agriculture, Fisheries and Food. Intakes were evaluated across four age groups, and major dietary sources were identified. Total polyamine intake increased with age, reaching 393 \u00b5mol/day in adults over 65 years. PU accounted for 49% of total intake, followed by SPD (29%) and SPM (22%). Plant-based foods were the primary contributors to SPD intake, particularly vegetables (36%), fruits (26%), and cereals (18%). PU intake was also predominantly plant-derived, mainly from fruits (58%) and vegetables (23%), whereas SPM intake was largely associated with meat products (59%). A theoretical Mediterranean diet model yielded a slightly higher total polyamine intake of 406.6 \u00b5mol/day and a substantially greater SPD intake than that observed in older adults (193.99 \u00b5mol/day versus 121.62 \u00b5mol/day). Overall, estimated polyamine intake in the Spanish population fell below the optimal level of 540 \u00b5mol/day proposed in the literature. These findings highlight the need for public health strategies promoting consumption of polyamine-rich foods, particularly vegetables, legumes, whole grains, and fruits, to support healthy aging and reduce the risk of age-related diseases."

In summary, this study highlights the bidirectional gut-lung axis as a therapeutic target in RILI progression and intervention, and reveals that FMT confers protection through metabolic remodeling and activation of the PPAR\u03b3-FAM134B-mediated ER-phagy pathway, providing a mechanistic basis for potential clinical translation."

"abstract_text": "ID: 42012729\nTitle: Spermidine in the aging brain: mechanisms, preclinical evidence, and clinical perspectives.\nAbstract: Spermidine, a naturally occurring polyamine, has emerged as a candidate modulator of brain aging because it regulates autophagy, mitochondrial function, oxidative balance, and neuroinflammatory signaling. This review summarizes current knowledge on spermidine biology, including its synthesis, catabolism, transport, and cell-specific handling in neurons and glia, with emphasis on ATP13A2/ATP13A4-dependent trafficking and EP300-linked autophagy. Preclinical studies consistently show that spermidine enhances proteostasis, reduces soluble amyloid-beta, improves microglial phagocytic activity, preserves mitochondrial fitness, and attenuates inflammatory responses in models of aging and neurodegeneration. Human evidence is encouraging but still limited: observational studies associate higher dietary spermidine intake with better cognitive outcomes, whereas interventional trials suggest possible benefits in subjective cognitive decline and mild dementia, with variable dose-dependent effects. Overall, spermidine is a biologically plausible nutraceutical for healthy brain aging, but larger, well-designed clinical trials are needed to define efficacy, bioavailability, safety, and optimal therapeutic use across prodromal, early-stage, and disease-specific patient populations."

"abstract_text": "ID: 42346630\nTitle: Sulforaphane as a Photoprotective Agent Against UV-Induced Skin Damage and Carcinogenesis: A Scoping Review.\nAbstract: Background/Objectives: Ultraviolet (UV) radiation is a major environmental carcinogen responsible for skin damage through oxidative stress, DNA damage, and inflammation. The nuclear factor erythroid 2-related factor 2 (Nrf2) pathway plays a central role in regulating cellular antioxidant defences against UV-induced damage. This scoping review aims to evaluate the potential role of sulforaphane (SFN), a known Nrf2 inducer, in protecting against UV-induced skin damage and photocarcinogenesis. Methods: A literature search was conducted in PubMed and Scopus from inception to 27 January 2026, to identify original experimental studies investigating SFN, glucoraphanin, or broccoli sprout extracts in the context of UV-induced skin damage. Eligible studies included in vitro, ex vivo, in vivo, and human models assessing outcomes related to oxidative stress, inflammation, molecular signalling pathways, and tumour development. Following screening and eligibility assessment, twelve studies were included in the qualitative synthesis. Results: The included studies suggest that SFN exerts photoprotective effects across multiple experimental models. In murine studies, SFN and SFN-rich extracts were associated with a reduction in tumour incidence, multiplicity, and volume following UV exposure. In human studies, topical SFN application reduced UV-induced erythema and induced cytoprotective enzyme expression, although clinical evidence remains limited. Mechanistically, SFN consistently activated the Nrf2 pathway, leading to increased expression of antioxidant and phase II detoxifying enzymes, and was associated with modulation of inflammatory responses and inhibition of MAPK/AP-1 signalling. Emerging evidence also indicates potential effects on UV-induced metabolic and epigenetic alterations. Conclusions: Current evidence supports a potential role for sulforaphane in mitigating UV-induced skin damage through activation of endogenous defence pathways. However, the available data are predominantly preclinical, and further well-designed clinical studies are needed to clarify its efficacy and translational relevance in humans."

While fetal lung signals are known to help initiate labor, the role of the placenta has remained unclear. Here we show that in steroid receptor coactivator (Src)-1 and -2 double-knockout mice, reduced placental amine oxidase, copper-containing 1 (Aoc1) leads to increased spermidine levels. In trophoblast cells, spermidine induces autophagy via hypusination of eukaryotic translation initiation factor 5\u2009A (EIF5A), reducing estrogen and prostaglandin production. Estrogen reciprocally increases Aoc1 expression via estrogen receptor-\u03b1 (ER\u03b1) in concert with SRC-1/2, forming a feedback loop maintaining placental autophagy homeostasis. AOC1 levels are elevated in preterm labor placentas from both mice and humans. Placenta-specific Aoc1 knockout dramatically delays labor by increasing trophoblast autophagy. Importantly, spermidine supplementation rescues inflammation-induced preterm labor in mice. Our findings reveal that placental AOC1-spermidine-EIF5A-autophagy axis is essential for parturition timing and offer a potential therapeutic strategy for preterm birth."

Here, we investigated whether the polyamine biosynthetic enzyme S-adenosylmethionine decarboxylase 1 (AMD1) regulates tubular senescence and repair outcomes after AKI and elucidated the underlying mechanism. AMD1 dynamics were examined in an ischemia-reperfusion injury model using male C57BL/6J mice by immunofluorescence. AAV-mediated Ksp promoter-driven tubule-specific Amd1 conditional knockdown male mice (Amd1 cKD) were used to assess renal injury, cell-cycle status, senescence, and remodeling, and exogenous spermidine was administered for rescue. DNA damage signaling and p53/p21 activation were evaluated by immunostaining, Western blotting, and EdU incorporation assays. AMD1 was predominantly expressed in the tubular epithelium, with prominent dynamic induction in proximal tubules early after IRI, but declined to baseline levels during the late phase, representing a relative metabolic insufficiency that correlated inversely with fibrosis. Compared with wild-type controls, Amd1 cKD mice exhibited aggravated tubular injury, an over two-fold increase in SA-\u03b2-gal-positive areas, elevated p21, and reduced Ki67+ proliferation. Conversely, spermidine supplementation improved renal function, reduced fibrosis by 75.3%, and decreased senescent regions by 74%. Mechanistically, AMD1 deficiency increased \u03b3H2AX-marked DNA damage and activated the p53/p21 checkpoint, whereas spermidine attenuated this response and restored DNA synthesis capacity. Collectively, tubular AMD1 acts as a metabolic checkpoint that preserves polyamine homeostasis to restrain p53/p21-dependent senescence, promote adaptive repair after AKI, and spermidine supplementation represents a potential strategy to mitigate maladaptive AKI-to-CKD progression."

Adult SD rats were randomized into Sham operation, PSCI model, TTM, rapamycin (an autophagy inducer), 3-methyladenine (an autophagy inhibitor), and TTM+3-MA groups, and rat models of cognitive impairment were established using a modified thread occlusion method. Cognitive function of the rats was assessed using Morris water maze test. Histopathological changes, neuronal apoptosis, dendritic spines, and protein expressions of FAM134B, LC3, ATG5, P62, GRP78, Bax, Bcl-2, IL-10, IL-1\u03b2, and TNF-\u03b1 were evaluated using HE, Nissl, TUNEL, Golgi staining, immunohistochemistry, immunofluorescence staining, and Western blotting. Compared with the sham-operated rats, the rat models of PSCI showed significantly prolonged escape latency, reduced target quadrant time and platform crossings, severe hippocampal damage, increased ATG5 and GRP78 expression, elevated apoptosis, increased IL-1\u03b2, TNF-\u03b1, Bax, GRP78, and P62 expressions, and decreased IL-10, Bcl-2, and LC3 expressions, with slightly increased FAM134B-LC3 and calnexin-LC3 co-localization. Compared with those in the model group, the rats receiving TTM treatment showed significantly shortened escape latency, increased target quadrant time and platform crossings, increased ATG5 and dendritic spines, decreased GRP78 expression, enhanced FAM134B-LC3 and calnexin-LC3 co-localization, reduced IL-1\u03b2, TNF-\u03b1, Bax, GRP78, and P62 expressions, and increased FAM134B, ATG5, LC3, IL-10, and Bcl-2 expressions; the rats treated with 3-MA showed the opposite changes. Excessive ER stress is activated early after stroke, shifting from adaptive to pro-apoptotic signaling, with insufficient ER-phagy flux. TTM modulates ER-phagy, alleviates ERS, reduces neuroinflammation and apoptosis, protects dendritic spines, and improves cognitive function in rats with PSCI. \u76ee\u7684:

"abstract_text": "ID: 42343845\nTitle: [Trillium tschonoskii Maxim saponin protects neurological function in rats with post-stroke cognitive impairment by promoting ER-phagy].\nAbstract: To investigate the mechanism that mediates the neuroprotective effects of Trillium tschonoskii Maxim (TTM) against post-stroke cognitive impairment (PSCI) in rats. Adult SD rats were randomized into Sham operation, PSCI model, TTM, rapamycin (an autophagy inducer), 3-methyladenine (an autophagy inhibitor), and TTM+3-MA groups, and rat models of cognitive impairment were established using a modified thread occlusion method. Cognitive function of the rats was assessed using Morris water maze test. Histopathological changes, neuronal apoptosis, dendritic spines, and protein expressions of FAM134B, LC3, ATG5, P62, GRP78, Bax, Bcl-2, IL-10, IL-1\u03b2, and TNF-\u03b1 were evaluated using HE, Nissl, TUNEL, Golgi staining, immunohistochemistry, immunofluorescence staining, and Western blotting. Compared with the sham-operated rats, the rat models of PSCI showed significantly prolonged escape latency, reduced target quadrant time and platform crossings, severe hippocampal damage, increased ATG5 and GRP78 expression, elevated apoptosis, increased IL-1\u03b2, TNF-\u03b1, Bax, GRP78, and P62 expressions, and decreased IL-10, Bcl-2, and LC3 expressions, with slightly increased FAM134B-LC3 and calnexin-LC3 co-localization. Compared with those in the model group, the rats receiving TTM treatment showed significantly shortened escape latency, increased target quadrant time and platform crossings, increased ATG5 and dendritic spines, decreased GRP78 expression, enhanced FAM134B-LC3 and calnexin-LC3 co-localization, reduced IL-1\u03b2, TNF-\u03b1, Bax, GRP78, and P62 expressions, and increased FAM134B, ATG5, LC3, IL-10, and Bcl-2 expressions; the rats treated with 3-MA showed the opposite changes. Excessive ER stress is activated early after stroke, shifting from adaptive to pro-apoptotic signaling, with insufficient ER-phagy flux. TTM modulates ER-phagy, alleviates ERS, reduces neuroinflammation and apoptosis, protects dendritic spines, and improves cognitive function in rats with PSCI. \u76ee\u7684:

ZEN exposure induces endoplasmic reticulum (ER) stress, oxidative stress, and autophagy activation. However, the involvement of inositol-requiring enzyme 1 (IRE1)-mediated ER-phagy in ZEN-induced ER stress and embryonic competence during in vitro culture (IVC) remains unclear. Porcine embryos were cultured with 2.5, 5, and 10\u202f\u03bcM ZEN for two days after in vitro fertilization (IVF) to assess blastocyst development. ZEN exposure caused a significant dose-dependent decrease in blastocyst formation, expanded blastocysts, and total cell number (p\u202f<\u202f0.05). ZEN-treated embryos exhibited increased DNA fragmentation along with elevated mitochondrial and intracellular Ca\u00b2\u207a levels (p\u202f<\u202f0.001), as confirmed using terminal deoxynucleotidyl transferase dUTP nick-end labeling assay and Rhod-2 and Fluo-4 AM staining. ER-tracker analysis revealed decreased ER fluorescence intensity and increased uneven cytoplasmic ER distribution in blastocysts exposed to 5 and 10\u202f\u03bcM ZEN (p\u202f<\u202f0.001). Western blotting showed activation of the unfolded protein response (UPR) with increased expression of glucose-regulated protein 78 (GRP78), p-IRE1, IRE1, p-c-Jun N-terminal kinase (JNK), JNK, C/EBP homologous protein (CHOP), and the autophagy marker microtubule-associated protein 1 light chain 3 beta (LC3B) (p\u202f<\u202f0.05), whereas the ER-phagy receptor family with sequence similarity 134, member B was downregulated. Tauroursodeoxycholic acid (TUDCA) alleviated ZEN-induced ER stress, restoring ER distribution and calcium homeostasis, reducing DNA damage, and improving blastocyst development. These findings suggest that ZEN disrupts IRE1 signaling and suppresses ER-phagy during early porcine embryo development, whereas TUDCA alleviates ER stress and improves embryonic competence during IVC."

Growing evidence shows that metabolites generated along the gut-brain axis regulate neuroinflammation. In this study, we demonstrate that oral administration of sodium butyrate (NaB) (300 or 600\u2009mg/kg/day) for 28 days lowered mortality and lessened neuropathological signs in mice infected with SS2 (SC19 strain). Butyrate prophylaxis was associated with lower bacterial loads in the blood and brain tissue, preserved expression of tight junction proteins (ZO-1, Claudin-5, and Occludin) in the brain, and maintained blood-brain barrier (BBB) integrity and permeability. 16S rRNA sequencing analysis revealed that SC19 infection significantly diminished the diversity and richness of the gut microbiota, notably depleting key short-chain fatty acid (SCFA)-producing bacterial taxa. Butyrate intervention restored microbial homeostasis and enriched SCFA-producing communities. Mechanistically, butyrate was associated with upregulated expression of nuclear factor erythroid 2-related factor 2 (Nrf2) and its downstream antioxidant effectors (heme oxygenase 1 [HO-1] and NQO1), while inhibiting phosphorylation of NF-\u03baB p65 and the secretion of proinflammatory cytokines (interleukin-1\u03b2 [IL-1\u03b2], interleukin-6 [IL-6], and tumor necrosis factor-\u03b1 [TNF-\u03b1]) in human cortical microvessels endothelial cells/D3 (hCMEC/D3) cells. Critically, these protective effects were abrogated upon pharmacological inhibition of Nrf2, indicating the critical role of Nrf2 in butyrate-mediated attenuation of neuroinflammation and oxidative stress.

Here, we identify FAM134B/RETREG1 as a specific ER-phagy receptor mediating amyloid precursor protein (APP) degradation. FAM134B directly interacts with ER-localized wild-type and familial mutant APP via their C-terminal domains and recruits LC3 through its LC3-interacting region (LIR) to promote APP delivery to phagophores for lysosomal degradation. In AD, epigenetic silencing at the FAM134B promoter suppresses its transcription by limiting TFEB/TFE3 binding despite their nuclear enrichment. This transcriptional suppression impairs ER-phagy, leading to APP accumulation and exacerbated AD pathology. AAV-mediated hippocampal expression of wild-type, but not LIR-mutant, FAM134B in 5XFAD mice restores ER-phagy, enhances APP clearance, reduces A\u03b2 deposition, preserves synaptic and myelin integrity, and improves cognitive performance. These findings establish FAM134B downregulation as an upstream pathogenic event in AD, suggesting ER-phagy enhancement as a promising strategy to suppress A\u03b2 generation at its source."

Current treatments offer limited efficacy, necessitating the development of innovative multitarget therapeutic strategies. Here, we present N3,N5-bis(2-(5-methoxy-1H-indol-3-yl)ethyl)-2,6-dimethyl-4-(2-nitrophenyl)pyridine-3,5-dicarboxamide (HCM-01), a novel compound developed to target multiple neurodegenerative pathways implicated in AD. In vitro assays included MTT-based cell viability analyses performed in two complementary experimental settings: primary neuronal cultures and astrocyte-based in vitro cell culture models exposed to glutamate. In primary hippocampal neuronal cultures, glutamate exposure induced a statistically significant reduction in cell viability compared with vehicle-treated controls, consistent with glutamate-induced excitotoxicity. Under these conditions, HCM-01 treatment resulted in a statistically significant improvement in neuronal viability, showing a greater protective effect compared with donepezil and memantine. In contrast, in astrocyte-based in vitro cultures, the applied glutamate concentration did not induce overt cytotoxicity, in line with the intrinsic neuroprotective and glutamate-buffering role of astrocytes. Accordingly, astrocytic experiments were designed to assess functional modulation of glutamate-handling mechanisms rather than cell survival. Western blot analysis in C8-D1A astrocytic cells demonstrated increased expression of excitatory amino acid transporter 2 (EAAT2) following HCM-01 treatment compared with control and reference drug-treated groups, suggesting modulation of astrocyte-mediated glutamate homeostasis. In parallel, redox analyses revealed that HCM-01 improved oxidative/antioxidative balance, as evidenced by increased total antioxidant capacity (TAC) and reduced total oxidant status (TOS), supporting an indirect antioxidant contribution to its functional effects. In vivo behavioral assessment of HCM-01 in a streptozotocin (STZ)-induced Alzheimer's model in female Sprague-Dawley rats demonstrated that administration of HCM-01 at doses of 50 mg/kg orally (oral, P.O. and intraperitoneal, I.P.) and 100 mg/kg (P.O.), significantly improved cognitive and memory functions in the passive avoidance (PA), Morris water maze (MWM), and locomotor activity tests. Moreover, histopathological and immunohistochemical analyses of different hippocampal regions revealed reduced neuronal damage, attenuation of tau pathology, antiamyloidogenic effect, and restoration of cholinergic function. Complementary in silico studies, including molecular docking, molecular dynamics simulations (MDS), and free energy calculations, suggested potential interactions of HCM-01 with the allosteric site of EAAT2. Taken together, these findings suggest that HCM-01 exerts neuroprotective effects against glutamate-induced excitotoxicity in primary hippocampal neurons while additionally modulating glutamatergic homeostasis and redox balance through functional mechanisms in astrocyte-based models, supporting its relevance as a multitarget preclinical candidate for early stage AD mechanisms."

This narrative review maps the adverse outcome pathways (AOPs) through which ethanol impairs synaptic function, primarily via interconnected cascades: TLR4/NF-\u03baB-mediated neuroinflammation (triggering microglial activation and pro-inflammatory cytokines TNF-\u03b1, IL-1\u03b2), CYP2E1-driven oxidative stress (generating ROS/RNS, 4-HNE, causing protein carbonylation and mitochondrial dysfunction), and glutamate excitotoxicity (mediated by GluN2B-NMDAR subunit shifts, Ca\u00b2\u207a overload, and astrocytic EAAT2/GLT-1 downregulation). These pathways converge to suppress BDNF/TrkB signaling (via miR-206 and impaired proBDNF cleavage), leading to deficits in synaptic protein synthesis (e.g., Arc) and trafficking (e.g., GluA1 endocytosis via STEP, impaired forward trafficking). Critically, these insults potentiate neuronal apoptosis through intrinsic (ROS/mitochondrial permeabilization, caspase-9/-3) and extrinsic (TNF-\u03b1/TNF-R1, caspase-8) pathways, executing irreversible synaptic loss via caspase-3 cleavage of PSD-95, spectrin, and cytoskeletal collapse. The structural consequences-dendritic simplification, reduced mature spine density, and PSD-95 nano-domain disorganization-manifest functionally as attenuated LTP, potentiated mGluR-LTD, and impaired STDP. This synaptic decay directly underpins cognitive impairments in pattern separation, contextual memory, and cognitive flexibility. Neuroinflammation (TLR4/NF-\u03baB) acts as a central amplifier, linking oxidative damage, excitotoxicity, and BDNF collapse to apoptotic synaptic deletion. Future research must address dose-dependency, subfield vulnerability, epigenetic regulation, and therapeutic strategies targeting TLR4, TrkB, mitochondrial antioxidants, and anti-apoptotic pathways."

Spermidine (SPD), a natural polyamine known to enhance autophagy and preserve cardiac function in aging and metabolic disorders, has not been systematically evaluated in the context of septic cardiomyopathy. To determine the therapeutic potential and mechanistic basis of SPD in septic cardiac dysfunction. Network pharmacology, RNA sequencing, a cecal ligation and puncture (CLP) mouse model, and multiple cellular assays were integrated to assess the protective actions of SPD. Mitochondrial function, mitophagy flux, and oxidative stress were evaluated using transmission electron microscopy (TEM), immunohistochemistry (IHC), Western blotting, structured illumination microscopy (SIM), mitochondrial membrane potential assays, oxygen consumption rate (OCR) analysis, and mitochondrial DNA (mtDNA) quantification. Transcriptomic clustering and pathway enrichment identified molecular targets, which were validated through siRNA-mediated gene silencing. SPD markedly attenuated SICM in vivo and in vitro by improving both mitochondrial quantity and quality. It restored sepsis-impaired mitophagy by upregulating LC3B and ATG7, promoting autophagosome maturation, and enhancing cellular ubiquitination. Transcriptomic profiling highlighted metallothionein-1 (MT1) as a key node in metal-ion response pathways. SPD activated the NRF2-MT1-SOD2 antioxidant axis, reduced mitochondrial reactive oxygen species (mtROS) under lipopolysaccharide (LPS) stimulation, and reversed sepsis-induced suppression of SOD2. MT1 knockdown abolished SPD-mediated SOD2 stabilization and mtROS clearance, confirming its essential role in SPD's cardioprotective effects. SPD mitigates SICM by orchestrating the restoration of mitochondrial quality control, normalization of mitophagic flux, and stabilization of cellular redox homeostasis. These findings support SPD as a promising therapeutic candidate for septic cardiomyopathy."

This study explores the interplay of endoplasmic reticulum stress (ERS), autophagy, and apoptosis in Cd-induced hepatotoxicity, focusing on whether ERS-driven autophagy protects against liver injury. Male SD rats (4\u202fweeks old, n\u202f=\u202f24) were acclimatized for 7\u202fdays and randomized into four groups receiving CdCl\u2082 at doses of 0, 0.5, 1, or 2\u202fmg/kg for 14 consecutive days. A second cohort (n\u202f=\u202f36) was similarly allocated to six groups: control, Cd, 4-PBA, Cd\u202f+\u202f4-PBA, CQ and Cd\u202f+\u202fCQ. All treatments were administered via daily intraperitoneal injection throughout the study. On day 14, blood and liver tissues were collected for analyses of liver function, hematological parameters, and histopathology. The expression of target factors was analyzed via qRT-PCR and Western blotting. Results indicate that Cd exposure causes liver injury and disordered hepatocyte morphology. ERS markers Grp78 and Caspase-12 and autophagy-related factors Beclin-1, Atg5, P62 and LC3 are upregulated at both mRNA and protein levels. The endoplasmic reticulum-phagy (ER-phagy) receptor FAM134B and the apoptosis effector cleaved Caspase3 are upregulated at the protein level. These findings indicate that Cd induces ERS, UPR activation, autophagy, reticulophagy, and apoptosis. The ERS inhibitor 4-PBA markedly attenuated Cd-induced hepatic injury. Compared with the Cd group, the Cd\u202f+\u202f4-PBA group showed decreased serum ALT and AST levels, as well as reduced RBC, WBC, MCH, and MCV counts. At the molecular level, mRNA and protein expression of ER stress markers Grp78, Caspase-12, PERK, eIF2\u03b1, ATF4, IRE1\u03b1, JNK, and ATF6 were all downregulated. Protein levels of the ER-phagy receptor FAM134B and the apoptosis effector cleaved Caspase-3 were also decreased. The autophagy inhibitor CQ aggravated such injury. Compared with the Cd group, the Cd\u202f+\u202fCQ group showed increased serum ALT and AST levels, as well as elevated RBC, MCH, and MCV counts. At the protein level, expression of the autophagy-related factors P62 and LC3, and the apoptosis effector cleaved Caspase-3 was significantly increased. These results show that Cd-induced ERS activates autophagy and reticulophagy mainly via the PERK, IRE1\u03b1, and ATF6 pathways, and this adaptive response clears autophagic substrates to alleviate hepatocyte damage."

Endoplasmic reticulum (ER) stress and autophagy are two interconnected stress responses critical for maintaining cellular homeostasis. Berbamine (BBM) is an important member of bis-benzy lisoquinoline alkaloid with diverse biological activities. This study aimed to identify the molecular target of BBM against T-2 toxin-induced hepatotoxicity, focusing on autophagy-ER stress crosstalk. We systematically evaluated autophagy and ER stress in human HepaRG cells using immunoblotting, transmission electron microscopy and an autophagy reporter assay. T-2 toxin was found to concurrently activate PINK1/Parkin-mediated mitophagy and suppress Keap1-mediated FAM134B ubiquitination-dependent ER-phagy, thereby triggering ER stress. Integrated evidence from molecular dynamics and western blot demonstrated that BBM upregulated and stabilized BNIP3, blocking the VAMP8-SNAP29 interaction to inhibit T-2 toxin-induced autophagy and subsequent ER stress. Moreover, in vivo mouse experiments demonstrated that 30\u202fmg/kg BBM significantly alleviated T-2 toxin-induced liver injury by suppressing both autophagic flux and ER stress; BBM significantly reduced serum levels of liver enzymes, ALT, and AST. Collectively, our findings elucidate a novel mechanism wherein T-2 toxin-induced mitophagy inhibits ER-phagy to drive ER stress-mediated liver injury and highlight the therapeutic potential of BBM in alleviating T-2 toxin-induced liver injury."

The mining of uranium and use of DU in modern weapons underly human exposure that disproportionally impacts military and tribal communities in the United States. Uranium's radiotoxic characteristics are understood, but its chemical hazards much less so. In zebrafish ( Danio rerio ) and human cell cultures we test the hypothesis that exposure to DU negatively impacts cellular function and development through disruption of mitochondrial metabolism. Using a novel shrapnel model with TEM/SEM+EDS, we showed uranium microparticles caused proximity-dependent mitochondrial disruption. In waterborne exposure paradigms, larval movement was reduced and hatching delayed as a result of reduced movement and not enzyme deficiencies in response to 18 ppb DU, below the MCL. Increased DNA damage accumulation was detected in exposed larva and cells. DNA-damage quantitative PCR of DU-exposed larvae showed increased damage in the ahr1 locus (nuclear gene) and decreased mitochondrial DNA (mtDNA) copy number, but mtDNA damage levels varied across experiments. Mitochondrial function was assessed using a resazurin-based assay in the presence and absence of antioxidants and showed diminished cytoplasmic reductive capacity. DU exposure alone did not enrich antioxidant gene expression, contrasting with arsenic exposure, a known ROS-inducer and Nrf2-activator. Sulforaphane (SFN), a potent Nrf2-activator, did not blunt the effects of DU exposure, despite activation of antioxidant response element (ARE) genes ( gstp and gss) , but did blunt the effects of arsenic exposure. The most enriched transcript in DU-exposed larvae coded for slingshot protein phosphatase ( ssh ), further exploration revealed ssh1b as the zebrafish-specific ortholog activated in response to DU, and inhibition using an identified SSH1 inhibitor, Sennoside A, partially rescued the metabolic and hatching defects observed. Our data points to a cytotoxic mechanism in which DU disrupts mitochondrial function through ssh1b enrichment that impairs normal mitophagy, leading to decreased cellular reductive potential independent of either ROS production or ARE-activation. Our results suggest that health impacts from DU exposure may be directly linked to impaired mitochondrial functions."

To address this question, we investigated a monogenic form of epilepsy (pyridoxine-dependent epilepsy) caused by aldehyde dehydrogenase 7 family member A1 (ALDH7A1) mutations. ALDH7A1 global knockout mice exhibited both seizure-associated and maladaptive affective behavioral phenotypes. However, seizure phenotypes were caused by ALDH7A1 deletion in hepatocytes whereas maladaptive affective behaviors were caused by ALDH7A1 deletion in astrocytes. Deletion in astrocytes disrupted astrocyte redox homeostasis, impairing regulation of extracellular ion concentrations and reducing neuronal activity in the prelimbic cortex. Sulforaphane, which activates the NRF2 antioxidant pathway, restored prelimbic neuronal activity and rescued maladaptive affective behaviors in ALDH7A1 knockout mice but did not prevent seizures.

Codonopsis pilosula is the sovereign herb in Shenling Baizhu Formula for ulcerative colitis therapy, and Codonopsis pilosula polysaccharides are its key active components, while their immunomodulatory effects and molecular mechanisms in Shenling Baizhu Formula against ulcerative colitis remain elusive. This study explored the critical role of Codonopsis pilosula polysaccharides and the spermidine-AMPK-mediated mitophagy-cGAS-STING inflammatory axis in regulating intestinal inflammation and ameliorating ulcerative colitis. A dextran sulfate sodium-induced ulcerative colitis mouse model was established to evaluate the indispensable role of Codonopsis pilosula polysaccharides in Shenling Baizhu Formula. Ultra-high performance liquid chromatography metabolomics and 16S ribosomal RNA sequencing were performed to identify key metabolites and gut microbiota. In vitro dextran sulfate sodium-induced ulcerative colitis cellular models (human colorectal adenocarcinoma Caco-2 and human normal colonic epithelial NCM460 cells) were constructed to validate the regulatory mechanism of spermidine on AMPK-mediated mitophagy, inflammatory balance and intestinal epithelial injury. Codonopsis pilosula polysaccharides were essential for the anti-ulcerative colitis efficacy of Shenling Baizhu Formula: removal of Codonopsis pilosula significantly aggravated colonic pathological lesions, intestinal inflammatory responses and oxidative stress in ulcerative colitis mice, whereas Codonopsis pilosula polysaccharides supplementation reversed these abnormal phenotypes (P\u00a0<\u00a00.05). Metabolomics and microbiomics confirmed that Codonopsis pilosula polysaccharides exerted therapeutic effects via spermidine (a key metabolite in glutamate metabolism pathway) and Muribaculaceae. Critically, in vitro dual-cell experiments verified that spermidine activated AMPK-mediated mitophagy to directly inhibit the hyperactivation of cGAS-STING inflammatory axis, thereby restoring intestinal inflammatory homeostasis and alleviating epithelial cell injury in ulcerative colitis. Codonopsis pilosula polysaccharides extracted from the sovereign herb Codonopsis pilosula in Shenling Baizhu Formula ameliorate dextran sulfate sodium-induced ulcerative colitis, and the core mechanism depends on spermidine-triggered AMPK-mediated mitophagy to suppress the cGAS-STING inflammatory signaling axis, which plays a pivotal role in regulating intestinal immunity and repairing mucosal epithelial damage."

Here, we identify the vitamin D receptor (Vdr) as a key anti-aging transcription factor whose expression in granulosa cells (GCs) declines with age. Using GCs-specific Vdr knockout (cVKO) mice and a Vdr-knockout (VKO) human granulosa-like cell line, we demonstrate that loss of Vdr triggers GCs aging and disrupts ovarian function. Integrated transcriptomic and metabolomic analyses from VKO and WT cells revealed that Vdr loss downregulates the de novo spermidine (SPD) biosynthesis by directly suppressing the transcription of ornithine decarboxylase (ODC1). This led to SPD depletion, which in turn inhibited DNA methyltransferase (DNMTs) activity, resulting in hypomethylation of the p53 promoter and activation of the p53/p21 pathway. Crucially, supplementation with either SPD or its upstream methyl donor S-adenosylmethionine (SAM) rescued cVKO and VKO cell aging, improved hormonal profiles and promoted follicular development in cVKO mice. Furthermore, both supplements effectively delayed ovarian aging and improved fertility in naturally aged mice. Our study unveils the Vdr-spermidine-DNMTs axis as a fundamental mechanism safeguarding against ovarian aging, highlighting SPD and SAM as promising therapeutic agents for age-related female infertility."

This study investigates the neuroprotective potential of Sulforaphane (SFN) in ameliorating ethidium bromide (EBRM)-induced MS-like pathology in Wistar rats. The efficacy of SFN at two doses (SFN1.5 and SFN3) was compared to FDA-approved Nrf2 activator drugs, omaveloxolone (OMV15) and dimethyl fumarate (DIMF50). EBRM administration caused neurobehavioral deficits, demyelination, oxidative stress, axonal degeneration, and inflammation. It disrupted key cellular pathways, including Nrf2/HO-1/SIRT-1, JAK/STAT-3/mTOR, and BACE-1/Gamma-secretase/MAPT, as well as caused neurotransmitter imbalances. SFN3 demonstrated significant improvement in motor function, cognitive performance, neurotransmitter levels antioxidant enzymes and alleviated neuroinflammation by modulating inflammatory cytokines. Molecular analyses showed that SFN3 increased Nrf2/HO-1/SIRT-1 levels while decreased pro-inflammatory and neurodegenerative markers such as STAT-3, mTOR, and BACE-1 levels. Gross pathological, Histopathological, and LFB studies indicated reduced demyelination and liver damage. SFN3 also demonstrated favourable systemic safety compared to OMV15. While DIMF50 showed the highest overall efficacy, SFN3 showed consistent modulation of pathological markers, neuroprotective effects, and safety profile. These findings suggest that SFN3 may have therapeutic potential for further translational research in MS. Future studies should validate its clinical relevance and explore combinatorial therapies with existing MS treatments to enhance therapeutic outcomes."

Here, we examined the effects of two haloacetamides, 2,2-dichloroacetamide (DCAcAm) and 2,2-dibromoacetamide (DBAcAm), on mouse oocyte maturation and identified the underlying mechanisms of toxicity. Both compounds markedly impaired meiotic spindle assembly and compromised the function of multiple organelles, including mitochondria, the endoplasmic reticulum, and the Golgi apparatus, primarily through autophagy dysregulation at specific exposure concentrations, as evidenced by the observation that more than half of the oocytes failed to progress beyond the MII stage. Spermidine supplementation effectively restored autophagic activity and rescued the associated cellular defects, thereby improving both nuclear and cytoplasmic maturation in oocytes. Collectively, these findings demonstrate that spermidine alleviates toxicant-induced deterioration of oocyte quality by regulating autophagy and highlight its potential therapeutic value for reproductive protection and clinical application."

Here, using state-of-the-art super-resolution multi-SIM imaging, we reveal that stresses (prolonged starvation, cholesterol dyshomeostasis, and high-Ca2+ insults) trigger the expansion of sheet ER subdomains containing high levels of luminal Ca2+ in mammalian cells, which are subsequently degraded by ER-phagy. Autophagosome formation and sequestration of ER sheets require the concerted actions of FAM134B and lipidated LC3, whereas the autophagy proteins ATG14 and ATG9 are partially dispensable. Electron microscopy and cryo-electron tomography show that the membranes of autophagosomes enclosing high-Ca2+-containing ER sheets are directly remodeled from the ER. The ER-localized cation channels PIEZO1 and TRPV1 are enriched at and mediate Ca2+ transients from high-Ca2+-containing ER sheets, triggering liquid-liquid phase separation of the autophagosome-initiating FIP200 complex to initiate ER-phagy. Thus, distinct mechanisms are employed for the formation of high-Ca2+-containing ER-enclosing autophagosomes and non-selective autophagosomes."

Alginate oligosaccharide (AOS), a marine-derived bioactive polysaccharide, exhibits prebiotic, anti-inflammatory and antioxidant properties that are effective against various inflammatory diseases. In this study, a mouse model of SAP was established by intraperitoneal injection of cerulein (100 \u03bcg/kg) and lipopolysaccharide (5 mg/kg), and the mice were pretreated with AOS (200 mg/kg) by gavage for 4 consecutive weeks to explore the potential protective efficacy and underlying mechanisms. The results shown that AOS attenuated the severity of SAP, as evidenced by reduced serum amylase and lipase levels, as well as alleviated histopathological injury in both pancreatic and ileal tissues. AOS suppressed the overproduction of pro-inflammatory cytokines (IL-1\u03b2, IL-6, TNF-\u03b1) in serum, pancreas, and ileum at protein or mRNA levels. Moreover, AOS effectively diminished pancreatic and ileal inflammatory infiltration and oxidative stress in SAP mice, accompanied by inhibited the TLR4/MyD88/NF-\u03baB pathway and activated the Nrf2/HO-1 antioxidant axis. Furthermore, AOS restored intestinal barrier integrity, as manifested by upregulated expression of tight junction proteins (claudin-1, occludin, ZO-1), reduced serum diamine oxidase, and decreased bacterial translocation from the gut to the pancreas. It was revealed by 16S rRNA sequencing that AOS ameliorated SAP-induced gut dysbiosis by restoring microbial diversity, normalizing the Firmicutes/Bacteroidetes ratio, enriching beneficial genera (Lactobacillus, Blautia), and enhancing cecal short-chain fatty acid (acetic, propionic, butyric acid) production. Collectively, our findings demonstrate that AOS exerts comprehensive protective effects against SAP through suppression of inflammatory signaling and oxidative stress, as well as restoring gut homeostasis. These results suggest that AOS may serve as a promising prebiotic-based nutritional strategy for the management of SAP."

Spermidine has been shown to counteract immunosenescence and induce autophagy in preclinical models, and its levels decline with age in humans. We conducted a double-blind, randomised, placebo-controlled pilot study in 40 adults over 65\u2009years of age following their third SARS-CoV-2 vaccine dose to assess the safety of Spermidine and its effects on vaccine-induced immunity. Daily oral supplementation (6\u2009mg, 13\u2009weeks) was well-tolerated. Vaccine non-responsiveness was common, and non-responders exhibited a distinct immune-senescence signature marked by elevated p16, mTOR signalling, and \u03b3-H2AX+ DNA damage in lymphocytes. Spermidine reversed these features and significantly enhanced spike-specific IgG secretion, memory B cell recall responses and neutralising antibody activity, specifically in non-responders. Single-cell RNA-seq after treatment revealed increased expression of TFEB targets and autophagy-related genes in B cells, in line with elevated autophagic flux. These findings suggest that targeting immune cell senescence with Spermidine may improve vaccine responsiveness in older adults and highlight immune-senescence markers as potential predictors of vaccine failure in ageing populations."

To our knowledge, no prior systematic review has synthesized evidence linking these metabolites to direct mitochondrial endpoints across all major metabolite classes. PubMed, Scopus, and Web of Science were systematically searched through March 2026 for studies examining direct mitochondrial endpoints in relation to ten classes of gut-derived metabolites. Gut-derived microbial metabolites exert diverse effects on mitochondrial function, ranging from bioenergetic enhancement to direct toxicity. After contextual evidence was excluded from the certainty assessment, four metabolite-mitochondrial outcome groupings had moderate certainty: butyrate, propionate, indoxyl sulfate, and lipopolysaccharide. Evidence for p-cresyl sulfate, H\u2082S, and urolithin A was rated low; evidence for the remaining metabolite classes was low or very low. Butyrate generally enhances mitochondrial biogenesis, ATP generation, and electron transport chain activity across multiple experimental models. Indoxyl sulfate generally impaired mitochondrial function, whereas p-cresyl sulfate produced concentration- and model-dependent effects. PGC-1\u03b1 emerges as a central regulatory node, integrating microbial metabolic signals to control mitochondrial biogenesis and oxidative metabolism. Many microbial metabolites demonstrate concentration-dependent biphasic effects. These findings support a mechanistic microbiome-mitochondrial framework in which diverse gut-derived molecules converge on a limited set of mitochondrial control nodes: electron transport chain activity, reactive oxygen species handling, biogenesis, and mitophagy. The evidence base is predominantly preclinical; these insights should be considered hypothesis-generating."

Polyamines, including putrescine, spermidine, and spermine, are vital microbial-host metabolites that support intestinal cell growth, autophagy, immune modulation, and mucosal repair. With advancing age, both host-derived and microbiota-mediated polyamine production declines, contributing to intestinal dysfunction and heightened vulnerability to inflammation and age-related disorders. This review explores the diet-microbiota-polyamine axis as a key biological framework influencing intestinal aging. It aims to integrate evidence on how dietary components and functional foods shape gut microbial ecology and, in turn, regulate microbial polyamine biosynthetic pathways that impact intestinal health. The review highlights major microbial contributors to polyamine metabolism, particularly lactic acid bacteria, and outlines mechanistic pathways linking polyamines to epithelial regeneration, inflammatory control, and gut barrier maintenance. It further discusses how age-associated dysbiosis disrupts these interactions and evaluates nutritional and microbial-based strategies such as fermented foods, prebiotics, and probiotics that may enhance polyamine availability and restore gut homeostasis. From the standpoint of food microbiology and human physiology, this synthesis underscores the translational potential of targeting microbial polyamine production through diet-based interventions. This article presents a narrative review synthesizing experimental, animal, and emerging human evidence on microbial and dietary polyamines in intestinal aging. In conclusion, modulating the diet-microbiota-polyamine axis represents a promising strategy to promote healthy intestinal aging, meriting deeper mechanistic exploration and validation through clinical studies."

Here, we found that SS-31 supplementation efficaciously improved oocyte maturation and early embryonic development from aged mice. Specifically, SS-31 remarkably restored the normal spindle/chromosome structure, fertilization ability, mitochondrial distribution, \u0394\u03a8m and mitophagy in aged oocytes. In contrast, SS-31 reduced oocyte aneuploidy, ROS accumulation and DNA damage. Mechanistically, single-cell transcriptome analysis reveals that SS-31 increased the maternal mRNA degradation, and the levels of genes associated with mitochondrial function and mitophagy in aged oocytes, such as Pink1, Rps27a, Tomm7 and Map1lc3b. In addition, SS-31 suppressed chromatin organization, histone modification and chromatin remodeling pathways. Moreover, we applied the single-cell untargeted metabolomics to identify that SS-31 increased the levels of spermidine and GSH, which were critical metabolites to protect oocytes against aging. Our data reveal that the beneficial effect of SS-31 on oocyte quality from advanced age is mainly mediated by restoration of mitochondrial function, mitophagy and anti-aging metabolites. It provides a potential strategy for improving oocyte quality to extend the reproductive lifespan of female animals."

Here, we identify ER-phagy as a previously unrecognized adaptive response to ISOXUS, an isoxazole derivative of usnic acid with selective anticancer activity. ISOXUS, a mitochondrial respiratory complex II inhibitor, induces bioenergetic collapse, reactive oxygen species accumulation, and extensive ER-derived vacuolization. Using integrated transcriptomic and metabolomic analyses, we demonstrate that ISOXUS selectively triggers ER-phagy in mitochondria-dependent MCF-7 breast cancer cells, but not in more glycolytic triple-negative MDA-MB-231 cells, revealing a cell-type-specific stress adaptation program. ER-phagy induction is associated with upregulation of the ER-phagy receptor FAM134B and depends on ER stress signalling, as pharmacological ER stress inhibition suppresses this process. Multi-omics profiling uncovers coordinated repression of mitochondrial gene expression together with activation of ER-centered metabolic pathways, including amino acid metabolism, the tricarboxylic acid cycle, and one-carbon folate metabolism. Notably, we also identify UFMylation-related genes (CDK5RAP3, DDRGK1) as novel candidates involved in ER-phagy induced by ISOXUS. Moreover, mitochondrial inhibitors, rotenone and oligomycin, unexpectedly promote, while antioxidant a-tocopherol blocks ISOXUS-induced ER-phagy, and all compounds partially improve cell viability under ISOXUS treatment, implicating ROS-driven ER-phagy as a cytoprotective mechanism. Integrated analyses further reveal activation of the integrated stress response (ISR), dominated by the PERK-ATF4 axis, driving glutamine-dependent metabolic reprogramming and suppression of apoptosis-related pathways. The late-stage autophagy inhibition lowered the glutathione synthesis after ISOXUS treatment. Collectively, our findings uncover a previously unappreciated mitochondria-ER-ISR axis that governs metabolic adaptation to ISOXUS and identifies ER-phagy as a potential therapeutic vulnerability in breast cancer."

Spermidine (SPD), a natural polyamine known to enhance autophagy and preserve cardiac function in aging and metabolic disorders, has not been systematically evaluated in the context of septic cardiomyopathy. To determine the therapeutic potential and mechanistic basis of SPD in septic cardiac dysfunction. Network pharmacology, RNA sequencing, a cecal ligation and puncture (CLP) mouse model, and multiple cellular assays were integrated to assess the protective actions of SPD. Mitochondrial function, mitophagy flux, and oxidative stress were evaluated using transmission electron microscopy (TEM), immunohistochemistry (IHC), Western blotting, structured illumination microscopy (SIM), mitochondrial membrane potential assays, oxygen consumption rate (OCR) analysis, and mitochondrial DNA (mtDNA) quantification. Transcriptomic clustering and pathway enrichment identified molecular targets, which were validated through siRNA-mediated gene silencing. SPD markedly attenuated SICM in vivo and in vitro by improving both mitochondrial quantity and quality. It restored sepsis-impaired mitophagy by upregulating LC3B and ATG7, promoting autophagosome maturation, and enhancing cellular ubiquitination. Transcriptomic profiling highlighted metallothionein-1 (MT1) as a key node in metal-ion response pathways. SPD activated the NRF2-MT1-SOD2 antioxidant axis, reduced mitochondrial reactive oxygen species (mtROS) under lipopolysaccharide (LPS) stimulation, and reversed sepsis-induced suppression of SOD2. MT1 knockdown abolished SPD-mediated SOD2 stabilization and mtROS clearance, confirming its essential role in SPD's cardioprotective effects. SPD mitigates SICM by orchestrating the restoration of mitochondrial quality control, normalization of mitophagic flux, and stabilization of cellular redox homeostasis. These findings support SPD as a promising therapeutic candidate for septic cardiomyopathy."

As an important carbohydrate, starch directly affects the homeostasis of glucose and lipid metabolism due to its digestion characteristics. Resistant starch (RS) with unique anti-digestive properties and prebiotic functions has become the current hotspot in dietary nutrition research for improving glucose and lipid metabolism disorders. This review summarizes the digestive characteristics of starch and the comprehensive effects of RS and its mechanisms for ameliorating metabolic diseases. Diets with high RS content not only optimize glucose homeostasis by delaying glucose release, the undigested fractions entering the colon also drive the metabolic regulatory network of the gut microbiota-gut-brain axis by activating the AMPK/ACC pathway to reduce fat accumulation, enhancing intestinal barrier function mediated by short-chain fatty acids (SCFAs), and promoting GLP-1/PYY neural signal transduction. These insights facilitate the design of new healthy foods and inspire new strategies for optimizing dietary nutrition and regulating glucose and lipid metabolism disorders caused by high-carbohydrate diets. \u4ee3\u8c22\u6027\u75be\u75c5\u5982\u80a5\u80d6\u3001\u7cd6\u5c3f\u75c5\u3001\u5fc3\u8840\u7ba1\u75be\u75c5\u7684\u5168\u7403\u6d41\u884c\u4e0e\u8425\u517b\u8fc7\u5269\u53ca\u996e\u98df\u6a21\u5f0f\u5931\u8861\u5bc6\u5207\u76f8\u5173\u3002\u6dc0\u7c89\u4f5c\u4e3a\u4eba\u7c7b\u4e3b\u8981\u80fd\u91cf\u6765\u6e90\u7684\u78b3\u6c34\u5316\u5408\u7269\uff0c\u5176\u6d88\u5316\u7279\u6027\u76f4\u63a5\u5f71\u54cd\u7cd6\u8102\u4ee3\u8c22\u7a33\u6001\u3002\u6297\u6d88\u5316\u6027\u6dc0\u7c89\uff08RS\uff09\u56e0\u5176\u72ec\u7279\u7684\u6297\u6d88\u5316\u7279\u6027\u4e0e\u76ca\u751f\u5143\u529f\u80fd\uff0c\u6210\u4e3a\u5f53\u524d\u6539\u5584\u7cd6\u8102\u4ee3\u8c22\u7d0a\u4e71\u7684\u81b3\u98df\u8425\u517b\u7814\u7a76\u7684\u70ed\u70b9\u3002\u672c\u6587\u7efc\u8ff0\u4e86\u6dc0\u7c89\u6d88\u5316\u7279\u6027\u4ee5\u53caRS\u6539\u5584\u4ee3\u8c22\u6027\u75be\u75c5\u7684\u7efc\u5408\u4f5c\u7528\u53ca\u76f8\u5173\u673a\u5236\u3002\u9ad8RS\u7684\u81b3\u98df\u4e0d\u4ec5\u901a\u8fc7\u5ef6\u7f13\u8461\u8404\u7cd6\u91ca\u653e\u4f18\u5316\u8840\u7cd6\u7a33\u6001\uff0c\u800c\u4e14\u672a\u6d88\u5316\u7684\u90e8\u5206\u8fdb\u5165\u7ed3\u80a0\u901a\u8fc7\u9a71\u52a8\u80a0\u9053\u83cc\u7fa4-\u80a0-\u8111\u8f74\u4ee3\u8c22\u8c03\u63a7\u7f51\u7edc\uff0c\u5176\u4e2d\u5305\u62ec\u6fc0\u6d3b\u817a\u82f7\u9178\u6d3b\u5316\u86cb\u767d\u6fc0\u9176/\u4e59\u9170\u8f85\u9176A\u7fa7\u5316\u9176\uff08AMPK/ACC\uff09\u901a\u8def\u51cf\u5c11\u8102\u80aa\u84c4\u79ef\u3001\u63d0\u5347\u77ed\u94fe\u8102\u80aa\u9178\uff08SCFAs\uff09\u4ecb\u5bfc\u7684\u80a0\u5c4f\u969c\u529f\u80fd\u4e0e\u80f0\u9ad8\u8840\u7cd6\u7d20\u6837\u80bd-1/\u80bdYY\uff08GLP-1/PYY\uff09\u795e\u7ecf\u4fe1\u53f7\u4f20\u5bfc\u3002\u8fd9\u4e0d\u4ec5\u5c06\u4e3a\u65b0\u578b\u5065\u5eb7\u98df\u54c1\u8bbe\u8ba1\u63d0\u4f9b\u7814\u7a76\u57fa\u7840\uff0c\u4e5f\u4e3a\u4f18\u5316\u81b3\u98df\u8425\u517b\uff0c\u8c03\u63a7\u9ad8\u78b3\u6c34\u996e\u98df\u5f15\u8d77\u7684\u7cd6\u8102\u4ee3\u8c22\u7d0a\u4e71\u63d0\u4f9b\u4e86\u65b0\u7684\u7814\u7a76\u601d\u8def\u3002."

Although PFOS exposure causes significant bioaccumulation and potential myelotoxicity, its specific impact on the chondrogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) remains to be elucidated. In this study, we established a murine model of PFOS exposure to isolate primary BMSCs and investigated this issue through in vitro differentiation assays, cellular senescence evaluations, and an in vivo subcutaneous implantation model using gelatin methacryloyl (GelMA) hydrogel scaffolds. Our results demonstrated that PFOS exposure triggered intracellular reactive oxygen species (ROS) accumulation and induced a senescent phenotype in BMSCs, characterized by restricted cellular proliferation and the release of senescence-associated secretory phenotype (SASP) factors, thereby markedly suppressing their chondrogenic capacity. Mechanistically, the inhibition of the Nrf2 signaling pathway by PFOS was identified as the principal driver of this process. Furthermore, both in vitro and in vivo assays confirmed that pharmacological activation using the Nrf2 agonist sulforaphane (SFN) effectively mitigated the senescent phenotype and restored the chondrogenic potential of PFOS-exposed BMSCs. Altogether, these findings elucidate the specific mechanisms of PFOS-induced stem cell toxicity and offer a potential strategy to overcome the resulting limitations in BMSC-based cartilage regeneration."

"abstract_text": "ID: 42104568\nTitle: PACS2 Alleviates Sepsis-Induced Myopathy by Activating ERK-MAPK Signalling Pathway to Suppress ER-Phagy.\nAbstract: Sepsis-induced myopathy (SIM) is a common and life-threatening complication, but its underlying mechanisms remain poorly understood. PACS2, a key resident protein at mitochondria-associated endoplasmic reticulum membranes (MAMs), regulates ER homeostasis under various pathological conditions. However, whether sepsis disrupts PACS2-dependent MAM integrity, thereby triggering ER dysfunction and muscle wasting, remains unexplored. We established a sepsis mouse model via cecal ligation and puncture (CLP) and assessed muscle function using compound muscle action potential (CMAP) recording and grip strength measurements. Muscle atrophy was evaluated by H&E staining and Western blotting. PACS2 expression was determined by Western blotting, immunohistochemistry and qRT-PCR. MAM integrity was assessed by immunofluorescence co-localization of IP3R and VDAC1, and ER-phagy (reticulophagy) activation was evaluated by transmission electron microscopy, Western blotting and fluorescence microscopy. To investigate the functional role of PACS2, adeno-associated virus (AAV)-mediated PACS2 overexpression was performed in mouse tibialis anterior muscle and gastrocnemius muscles, followed by RNA-sequencing analysis. The MAPK pathway proteins p-ERK, p-P38 and p-JNK levels were assessed by Western blotting, and the involvement of ERK-MAPK signalling was tested pharmacologically via intraperitoneal injection of the ERK inhibitor SCH772984. Septic mice developed progressive skeletal muscle atrophy (p\u2009<\u20090.001) and dysfunction (p\u2009<\u20090.01), accompanied by 56% reduction in PACS2 expression at 96\u2009h post-CLP (p\u2009<\u20090.01), 25% decrease in MAM integrity (p\u2009<\u20090.05) and subsequent activation of FAM134B-mediated ER-phagy (p\u2009<\u20090.01). AAV-mediated PACS2 overexpression significantly alleviated muscle atrophy by restoring MAM integrity by 28% (p\u2009<\u20090.01), reducing FAM134B expression by 43% (p\u2009<\u20090.01) and attenuating ER-phagy (p\u2009<\u20090.01). Co-immunoprecipitation revealed no detectable direct protein-protein interaction between PACS2 and FAM134B. Transcriptome sequencing and Western blotting analysis demonstrated that PACS2 overexpression specifically activated the ERK-MAPK signalling pathway (55% increase in p-ERK, p\u2009<\u20090.01) without affecting p-P38 or p-JNK levels (p>0.05), which suppressed FAM134B-mediated ER-phagy (p\u2009<\u20090.05) and ameliorated muscle atrophy (p\u2009<\u20090.05) by inhibiting nuclear translocation of TFEB (p\u2009<\u20090.01). Pharmacological ERK inhibition with SCH772984 abolished the protective effects of PACS2 by promoting TFEB nuclear translocation (p\u2009<\u20090.001) and TFEB-mediated FAM134B expression (p\u2009<\u20090.001). Our findings demonstrate that SIM is closely associated with disrupted MAM integrity. PACS2 plays a critical role in maintaining MAM structural integrity and regulating FAM134B-mediated ER-phagy through the ERK-MAPK-TFEB signalling axis, thereby providing novel mechanistic insights and potential therapeutic targets for SIM."

To address this question, we investigated a monogenic form of epilepsy (pyridoxine-dependent epilepsy) caused by aldehyde dehydrogenase 7 family member A1 (ALDH7A1) mutations. ALDH7A1 global knockout mice exhibited both seizure-associated and maladaptive affective behavioral phenotypes. However, seizure phenotypes were caused by ALDH7A1 deletion in hepatocytes whereas maladaptive affective behaviors were caused by ALDH7A1 deletion in astrocytes. Deletion in astrocytes disrupted astrocyte redox homeostasis, impairing regulation of extracellular ion concentrations and reducing neuronal activity in the prelimbic cortex. Sulforaphane, which activates the NRF2 antioxidant pathway, restored prelimbic neuronal activity and rescued maladaptive affective behaviors in ALDH7A1 knockout mice but did not prevent seizures. These studies implicate astrocyte redox homeostasis and prelimbic hypoactivity in maladaptive affective behavioral phenotypes in a congenital form of epilepsy, which are mechanistically and therapeutically dissociable from seizure pathophysiology."

ZEN exposure induces endoplasmic reticulum (ER) stress, oxidative stress, and autophagy activation. However, the involvement of inositol-requiring enzyme 1 (IRE1)-mediated ER-phagy in ZEN-induced ER stress and embryonic competence during in vitro culture (IVC) remains unclear. Porcine embryos were cultured with 2.5, 5, and 10\u202f\u03bcM ZEN for two days after in vitro fertilization (IVF) to assess blastocyst development. ZEN exposure caused a significant dose-dependent decrease in blastocyst formation, expanded blastocysts, and total cell number (p\u202f<\u202f0.05). ZEN-treated embryos exhibited increased DNA fragmentation along with elevated mitochondrial and intracellular Ca\u00b2\u207a levels (p\u202f<\u202f0.001), as confirmed using terminal deoxynucleotidyl transferase dUTP nick-end labeling assay and Rhod-2 and Fluo-4 AM staining. ER-tracker analysis revealed decreased ER fluorescence intensity and increased uneven cytoplasmic ER distribution in blastocysts exposed to 5 and 10\u202f\u03bcM ZEN (p\u202f<\u202f0.001). Western blotting showed activation of the unfolded protein response (UPR) with increased expression of glucose-regulated protein 78 (GRP78), p-IRE1, IRE1, p-c-Jun N-terminal kinase (JNK), JNK, C/EBP homologous protein (CHOP), and the autophagy marker microtubule-associated protein 1 light chain 3 beta (LC3B) (p\u202f<\u202f0.05), whereas the ER-phagy receptor family with sequence similarity 134, member B was downregulated. Tauroursodeoxycholic acid (TUDCA) alleviated ZEN-induced ER stress, restoring ER distribution and calcium homeostasis, reducing DNA damage, and improving blastocyst development. These findings suggest that ZEN disrupts IRE1 signaling and suppresses ER-phagy during early porcine embryo development, whereas TUDCA alleviates ER stress and improves embryonic competence during IVC."

In this review we summarize the current knowledge on ER-phagy receptors, and emerging evidence linking ER-phagy dysfunction to various disease pathologies including neurological disorders, cancer, metabolic diseases, cardiovascular diseases, infections and immune disorders. Recent evidence shows that ER-phagy receptors can form novel ER-derived structures, such as ER-tubular bodies (ER-TBs) consisted of ATL3 and RTN3L, which mediate Golgi-bypassing unconventional protein secretion under stress conditions, revealing non-degradative functions of these receptors beyond quality control. Targeting ER-phagy receptors may provide insights into potential therapeutic strategies for diseases associated with this fundamental cellular process."

In a total lung irradiation (TLI) mouse model, FMT significantly alleviated pulmonary histopathological injury, inflammatory responses, oxidative stress, and collagen deposition during fibrogenesis. Concurrently, FMT improved intestinal motility, enhanced mucosal barrier integrity, and restored TLI-induced dysbiosis in gut microbiota diversity and community structure. Metabolomic analysis revealed that TLI significantly disrupted the metabolism of unsaturated fatty acids and arachidonic acid (AA), whereas FMT partially restored these metabolic networks. Transcriptomic and ultrastructural analyses indicated that RILI suppressed endoplasmic reticulum (ER) protein processing and induced ER swelling, while FMT promoted protective ER-phagy and facilitated restoration of ER morphology. Integrated multi-omics analysis further identified the AA metabolism as a key component of FMT-mediated protection, with its alterations closely associated with pulmonary tissue repair. Further in vivo and in vitro experiments demonstrated that AA binds to and activates the nuclear receptor PPAR\u03b3, leading to transcriptional upregulation of FAM134B, promoting protective ER-phagy and ameliorating RILI.

"abstract_text": "ID: 42197044\nTitle: Dietary Polyamine Intake Across Age Groups in Spain: A Comprehensive Assessment.\nAbstract: Polyamines, including putrescine (PU), spermidine (SPD), and spermine (SPM), are ubiquitous bioactive compounds essential for cell proliferation, genomic stability, autophagy, and the regulation of oxidative and inflammatory responses. Growing evidence, particularly for SPD, suggests that polyamine-rich diets may protect against age-related conditions such as cardiovascular disease, metabolic syndrome, and neurodegenerative disorders. As endogenous polyamine synthesis declines with age, dietary intake becomes increasingly important, especially in older adults. This study estimated each polyamine (PU, SPD and SPM) and total polyamine intake in the Spanish population using food consumption data from the Spanish Ministry of Agriculture, Fisheries and Food. Intakes were evaluated across four age groups, and major dietary sources were identified. Total polyamine intake increased with age, reaching 393 \u00b5mol/day in adults over 65 years. PU accounted for 49% of total intake, followed by SPD (29%) and SPM (22%). Plant-based foods were the primary contributors to SPD intake, particularly vegetables (36%), fruits (26%), and cereals (18%). PU intake was also predominantly plant-derived, mainly from fruits (58%) and vegetables (23%), whereas SPM intake was largely associated with meat products (59%). A theoretical Mediterranean diet model yielded a slightly higher total polyamine intake of 406.6 \u00b5mol/day and a substantially greater SPD intake than that observed in older adults (193.99 \u00b5mol/day versus 121.62 \u00b5mol/day). Overall, estimated polyamine intake in the Spanish population fell below the optimal level of 540 \u00b5mol/day proposed in the literature. These findings highlight the need for public health strategies promoting consumption of polyamine-rich foods, particularly vegetables, legumes, whole grains, and fruits, to support healthy aging and reduce the risk of age-related diseases."

The nuclear factor erythroid 2-related factor 2 (Nrf2) pathway plays a central role in regulating cellular antioxidant defences against UV-induced damage. This scoping review aims to evaluate the potential role of sulforaphane (SFN), a known Nrf2 inducer, in protecting against UV-induced skin damage and photocarcinogenesis. Methods: A literature search was conducted in PubMed and Scopus from inception to 27 January 2026, to identify original experimental studies investigating SFN, glucoraphanin, or broccoli sprout extracts in the context of UV-induced skin damage. Eligible studies included in vitro, ex vivo, in vivo, and human models assessing outcomes related to oxidative stress, inflammation, molecular signalling pathways, and tumour development. Following screening and eligibility assessment, twelve studies were included in the qualitative synthesis. Results: The included studies suggest that SFN exerts photoprotective effects across multiple experimental models. In murine studies, SFN and SFN-rich extracts were associated with a reduction in tumour incidence, multiplicity, and volume following UV exposure. In human studies, topical SFN application reduced UV-induced erythema and induced cytoprotective enzyme expression, although clinical evidence remains limited. Mechanistically, SFN consistently activated the Nrf2 pathway, leading to increased expression of antioxidant and phase II detoxifying enzymes, and was associated with modulation of inflammatory responses and inhibition of MAPK/AP-1 signalling. Emerging evidence also indicates potential effects on UV-induced metabolic and epigenetic alterations. Conclusions: Current evidence supports a potential role for sulforaphane in mitigating UV-induced skin damage through activation of endogenous defence pathways. However, the available data are predominantly preclinical, and further well-designed clinical studies are needed to clarify its efficacy and translational relevance in humans."

DCFH\u2011DA analysis was performed to evaluate the expression of ROS in different treatment groups. Furthermore, ELISA was used to evaluate the expressions of IL\u20111\u03b2, IL\u20116 and TNF\u2011\u03b1 in each group. SFN notably decreased the serum levels of Scr and BUN and decreased the expression levels of kidney injury molecule\u20111 and neutrophil gelatinase\u2011associated lipocalin in the cisplatin\u2011induced model group. Histopathological examination revealed attenuated renal structural damage and preserved tubular architecture in the SFN intervention group. Furthermore, SFN notably inhibited the apoptosis, inflammation and oxidative stress of renal tissues induced with cisplatin. Additionally, SFN markedly upregulated NRF2. In vitro, the NRF2 inhibitor ML385 partially attenuated the effects of SFN on the viability, apoptosis, inflammation and oxidative stress of HK\u20112 model cells. The present study indicated that SFN exerted its nephroprotective effect through NRF2\u2011mediated anti\u2011inflammatory, antioxidant and anti\u2011apoptotic mechanisms, positioning SFN as a promising therapeutic candidate for clinical management of chemotherapy\u2011associated kidney injury."

Codonopsis pilosula is the sovereign herb in Shenling Baizhu Formula for ulcerative colitis therapy, and Codonopsis pilosula polysaccharides are its key active components, while their immunomodulatory effects and molecular mechanisms in Shenling Baizhu Formula against ulcerative colitis remain elusive. This study explored the critical role of Codonopsis pilosula polysaccharides and the spermidine-AMPK-mediated mitophagy-cGAS-STING inflammatory axis in regulating intestinal inflammation and ameliorating ulcerative colitis. A dextran sulfate sodium-induced ulcerative colitis mouse model was established to evaluate the indispensable role of Codonopsis pilosula polysaccharides in Shenling Baizhu Formula. Ultra-high performance liquid chromatography metabolomics and 16S ribosomal RNA sequencing were performed to identify key metabolites and gut microbiota. In vitro dextran sulfate sodium-induced ulcerative colitis cellular models (human colorectal adenocarcinoma Caco-2 and human normal colonic epithelial NCM460 cells) were constructed to validate the regulatory mechanism of spermidine on AMPK-mediated mitophagy, inflammatory balance and intestinal epithelial injury. Codonopsis pilosula polysaccharides were essential for the anti-ulcerative colitis efficacy of Shenling Baizhu Formula: removal of Codonopsis pilosula significantly aggravated colonic pathological lesions, intestinal inflammatory responses and oxidative stress in ulcerative colitis mice, whereas Codonopsis pilosula polysaccharides supplementation reversed these abnormal phenotypes (P\u00a0<\u00a00.05). Metabolomics and microbiomics confirmed that Codonopsis pilosula polysaccharides exerted therapeutic effects via spermidine (a key metabolite in glutamate metabolism pathway) and Muribaculaceae. Critically, in vitro dual-cell experiments verified that spermidine activated AMPK-mediated mitophagy to directly inhibit the hyperactivation of cGAS-STING inflammatory axis, thereby restoring intestinal inflammatory homeostasis and alleviating epithelial cell injury in ulcerative colitis. Codonopsis pilosula polysaccharides extracted from the sovereign herb Codonopsis pilosula in Shenling Baizhu Formula ameliorate dextran sulfate sodium-induced ulcerative colitis, and the core mechanism depends on spermidine-triggered AMPK-mediated mitophagy to suppress the cGAS-STING inflammatory signaling axis, which plays a pivotal role in regulating intestinal immunity and repairing mucosal epithelial damage."

Adult SD rats were randomized into Sham operation, PSCI model, TTM, rapamycin (an autophagy inducer), 3-methyladenine (an autophagy inhibitor), and TTM+3-MA groups, and rat models of cognitive impairment were established using a modified thread occlusion method. Cognitive function of the rats was assessed using Morris water maze test. Histopathological changes, neuronal apoptosis, dendritic spines, and protein expressions of FAM134B, LC3, ATG5, P62, GRP78, Bax, Bcl-2, IL-10, IL-1\u03b2, and TNF-\u03b1 were evaluated using HE, Nissl, TUNEL, Golgi staining, immunohistochemistry, immunofluorescence staining, and Western blotting. Compared with the sham-operated rats, the rat models of PSCI showed significantly prolonged escape latency, reduced target quadrant time and platform crossings, severe hippocampal damage, increased ATG5 and GRP78 expression, elevated apoptosis, increased IL-1\u03b2, TNF-\u03b1, Bax, GRP78, and P62 expressions, and decreased IL-10, Bcl-2, and LC3 expressions, with slightly increased FAM134B-LC3 and calnexin-LC3 co-localization. Compared with those in the model group, the rats receiving TTM treatment showed significantly shortened escape latency, increased target quadrant time and platform crossings, increased ATG5 and dendritic spines, decreased GRP78 expression, enhanced FAM134B-LC3 and calnexin-LC3 co-localization, reduced IL-1\u03b2, TNF-\u03b1, Bax, GRP78, and P62 expressions, and increased FAM134B, ATG5, LC3, IL-10, and Bcl-2 expressions; the rats treated with 3-MA showed the opposite changes. Excessive ER stress is activated early after stroke, shifting from adaptive to pro-apoptotic signaling, with insufficient ER-phagy flux. TTM modulates ER-phagy, alleviates ERS, reduces neuroinflammation and apoptosis, protects dendritic spines, and improves cognitive function in rats with PSCI. \u76ee\u7684:

Here, we identify FAM134B/RETREG1 as a specific ER-phagy receptor mediating amyloid precursor protein (APP) degradation. FAM134B directly interacts with ER-localized wild-type and familial mutant APP via their C-terminal domains and recruits LC3 through its LC3-interacting region (LIR) to promote APP delivery to phagophores for lysosomal degradation. In AD, epigenetic silencing at the FAM134B promoter suppresses its transcription by limiting TFEB/TFE3 binding despite their nuclear enrichment. This transcriptional suppression impairs ER-phagy, leading to APP accumulation and exacerbated AD pathology. AAV-mediated hippocampal expression of wild-type, but not LIR-mutant, FAM134B in 5XFAD mice restores ER-phagy, enhances APP clearance, reduces A\u03b2 deposition, preserves synaptic and myelin integrity, and improves cognitive performance. These findings establish FAM134B downregulation as an upstream pathogenic event in AD, suggesting ER-phagy enhancement as a promising strategy to suppress A\u03b2 generation at its source."

Previously, the 1st known ER-phagy receptor gene RETREG1 (RETR1)/FAM134B gene was reported to restrict Ebola virus (EBOV) replication in vivo by inhibiting the viral glycoprotein (GP) and viral protein 40 kDa (VP40) expression, but this mechanism remains unknown. Here, we identify the truncated RETR1/FAM134B isoform 2 (RETR1-2), but not its full-length protein RETR1, as an ER-phagy receptor that targets EBOV-GP for degradation. RETR1-2 broadly triggers GP degradation across ebolavirus species but not Marburg virus and inhibits EBOV replication. Mechanistically, RETR1-2 recognizes EBOV-GP via its luminal domain, undergoes GP-induced oligomerization, and directs GP-containing ER membranes to lysosomes through canonical macro-autophagy. Using unbiased mass spectrometry, we identified TOLLIP as the key cytoplasm adaptor for RETR1-2, which also requires cooperation with the ER chaperone calnexin for EBOV-GP degradation. Notably, the PI3P-binding C2 domain of TOLLIP mediates its interaction with RETR1-2, and the EBOV-GP degradation occurs independently of ubiquitination, revealing an unexpected role for TOLLIP in ER-phagy. Furthermore, EBOV-VP40 antagonizes this pathway by selectively targeting RETR1-2 for macroautophagic degradation independently of TOLLIP, thereby restoring GP expression and viral infectivity. Nevertheless, RETR1-2 reciprocally degrades VP40 via a similar mechanism. Together, these findings define a calnexin-TOLLIP-RETR1-2 axis that links ER quality control to ER-phagy-mediated antiviral restriction and uncover a reciprocal host-virus arms race centered on selective macro-autophagy."

However, the mechanisms by which host proteins utilize ER-phagy to regulate innate immune response during viral infection remains largely unclear. Here, we uncover the regulatory crosstalk between innate immune adapter, ER retention protein Stimulator of Interferon Genes (STING), and the G protein-coupled receptor ADGRE5/CD97 (Cluster of Differentiation 97). Our results demonstrate that CD97 suppresses the STING-mediated type-I interferon (IFN-I) response against DNA virus and cytosolic DNA, thereby promoting herpes simplex virus type 1 (HSV-1) replication in both cells and mice. CD97 facilitates the recruitment of the ER-phagy receptor, FAM134B (family with sequence similarity 134, member B), to initiate ER-phagy, resulting in the degradation of STING subsequent to DNA virus infection. Furthermore, Cd97-deficient mice exhibit higher IFN-I response and greater resistance to HSV-1 infection. Additionally, our findings reveal that inhibiting CD97 with sanguinarine effectively disrupts HSV-1 replication. These findings shed light on the role of CD97 in the innate immune response against DNA virus infections and offer valuable checkpoint for anti-viral STING activation."

Clostridium butyricum (C. butyricum), a probiotic, can alleviate cognitive decline in individuals with various neurodegenerative diseases, and C. butyricum might generate SPD. However, the role of C. butyricum in natural brain aging and the efficacy of C. butyricum and the metabolite SPD in ameliorating age-related cognitive decline remain unclear. Here, we investigated the effects of C. butyricum and its metabolite SPD on cognitive decline during natural brain aging and the mechanisms underlying these effects. Aged rats\u00a0(aged 17 months, n\u202f=\u202f12 per group) were randomly divided into normal saline (NS), C. butyricum (1\u202f\u00d7108\u223c109 CFU/ml, by gavage for two months) and SPD (6.5\u202fmg/kg/d, by gavage for one month) groups. Compared with the NS group, the C. butyricum and SPD groups presented improved spatial reference and recognition memory, reduced aging marker levels by immunohistochemical staining, improved synaptic plasticity-related tissue structure by transmission electron microscopy and Golgi staining, and increased level of synaptophysin and BDNF by immunofluorescence staining and western blotting in the brain. Furthermore, treatment with C. butyricum and SPD enhanced intestinal barrier function and decreased serum proinflammatory factor levels and brain tissue damage due to oxidative stress. There were no significant differences in relevant indicators between the C. butyricum and SPD groups. In conclusion, C. butyricum and its metabolite SPD may delay the cognitive decline caused by normal brain aging by reducing oxidative stress and inflammation."

This review aim of the synthesize mechanistic evidence on \u03b2-sitosterol as a multi-target phytochemical and clarify how its actions connect to gut-brain axis modulation in neurodegeneration. The integrated mechanistic framework linking \u03b2-sitosterol's effects on cholesterol homeostasis, neuroinflammation, mitochondrial function, cholinergic signaling, and microbiota-barrier integrity to cognitive outcomes. Scope: preclinical and early translational evidence on \u03b2-sitosterol alone and with complementary phytochemicals, including nano-delivery strategies. Increasing evidence highlights phytochemicals as promising multi-target therapeutic agents capable of modulating these interconnected pathological processes. \u03b2-Sitosterol exhibits broad activity by regulating cholesterol metabolism, suppressing neuroinflammation, restoring redox balance, preserving mitochondrial function, and inhibiting important Alzheimer's diseases targets, including acetylcholinesterase and butyrylcholinesterase. The mechanisms action of \u03b2-sitosterol may (i) dampen microglial activation via TLR4/NF-\u03baB signaling, (ii) activate Nrf2-dependent antioxidant responses (Nrf2/HO-1), (iii) support mitochondrial function and reduce ROS, (iv) stabilize membrane cholesterol and modulate amyloidogenic processing, and (v) inhibit acetylcholinesterase/butyrylcholinesterase to restore cholinergic tone. Complementary showing a neuroprotective effect actions of other phytochemicals such as curcumin, resveratrol, sulforaphane, and sinapic acid further enhance neuroprotection by modulating pathways like Nrf2/HO-1, TLR4/NF-\u03baB, PI3K/Akt, and autophagy. Collectively, preclinical studies demonstrate that diverse botanical extracts significantly improve cognitive performance, reduce amyloid burden, restore cholinergic function, and attenuate neuroinflammation and oxidative damage. Emerging preclinical evidence suggests in rodent models of amyloid pathology, \u03b2-sitosterol (5-50\u202fmg/kg) has been reported to improve memory in behavioral tests and reduce markers of neuroinflammation and oxidative stress; gut-brain effects include microbiota remodeling and enhanced barrier integrity, which correlate with reduced neuroimmune activation. Advances in nano-delivery systems and functional food formulations substantially improve phytochemical stability, bioavailability, and brain targeting. Available evidence is chiefly preclinical; clinical translation will require standardized dosing, pharmacokinetic and blood-brain barrier penetration studies, and randomized trials with microbiome and cognitive endpoints. Collectively, these findings position phytochemicals as promising candidates for multi-target disease modification and the development of next-generation neurotherapeutic strategies."

This study describes and evaluates a curriculum-integrated learning experience linking experimental pharmacology, cell culture and Nrf2-related gene expression analysis in third-year Biotechnology students. A total of 32 students participated in the survey-based evaluation. The activity used A549 cells, sulforaphane as an Nrf2-activating compound and tert-butyl hydroperoxide as a pro-oxidant stimulus. Students followed an integrated workflow combining treatment design, cell culture handling, Nrf2-related gene selection, PCR-based gene expression analysis and scientific writing. Perceived learning was assessed using paired pre-post Likert-scale items and analyzed with the Wilcoxon matched-pairs signed-rank test. Post-intervention perceptions, satisfaction and open-ended feedback were analyzed descriptively. Students showed significant improvements in all five pre-post items assessing perceived confidence or familiarity (p value < 0.0001). The proportion of students showing improvement ranged from 81.3% to 100%. Post-intervention responses indicated positive perceptions of interdisciplinary integration, technical competencies, digital competencies, data interpretation and research/professional development. Overall satisfaction was high, with a mean score of 8.50 \u00b1 1.10 out of 10; 87.5% of students rated the activity with a score of 8 or higher. Qualitative feedback highlighted interdisciplinary integration and global understanding of the experimental workflow as key strengths. This curriculum-integrated learning experience was associated with perceived gains across pharmacological, cellular and molecular components of a biotechnology workflow. The intervention may provide a transferable model for integrating experiential, research-oriented and competency-based learning in undergraduate biotechnology education."

Aim of this review is to update the knowledge of Nrf2 as neuroprotective agent of PD. Activation of Nrf2, a transcription factor that regulates the expression of antioxidant and cytoprotective genes, has emerged as a promising therapeutic strategy for PD. Nrf2 is a master regulator of the cellular antioxidant response and is responsible for activating the expression of genes that encode antioxidant enzymes such as superoxidedismutase, catalase, and glutathione peroxidase. Pharmacological agents such as sulforaphane, curcumin, and resveratrol have been shown to activate Nrf2 and upregulate the expression of antioxidant genes in preclinical PD models. Clinical trials are currently underway to evaluate the efficacy of these pharmacological agents in patients with PD. While the neuroprotective role of Nrf2 in PD holds great promise for the development of novel therapies, there are several challenges and limitations that need to be addressed in order to harness the full potential of this pathway in the clinic. Overcoming these obstacles will require interdisciplinary collaborations, innovative research approaches, and a greater understanding of the complex pathophysiology of PD. By addressing these challenges, we can move closer to developing effective neuroprotective therapies that can slow or stop the progression of PD and improve the quality of life for patients with this devastating disease."

However, small molecules targeting CLDN14 remain unexplored. Here, we identified mupirocin (MUP), a clinically approved topical antibiotic, as a modulator of CLDN14 protein expression. Quartz crystal microbalance analysis revealed interaction between MUP and recombinant CLDN14 protein with a dissociation constant (Kd) of 2.59\u00a0\u00b1\u00a00.54\u00a0\u03bcM. MUP did not alter CLDN14 mRNA levels but reduced CLDN14 protein stability. Pharmacological inhibition of clathrin-mediated endocytosis and lysosomal degradation significantly reversed the MUP-induced reduction of CLDN14 protein. These results suggest MUP accelerates endocytosis-lysosomal degradation of CLDN14 protein. Other antibiotics failed to decrease CLDN14 expression. Functionally, MUP increased paracellular permeability to mineral ions and enhanced the transepithelial flux of doxorubicin (DXR), an anthracycline anticancer drug, and lucifer yellow, an aqueous small compound. In DLD-1 spheroids, MUP reduced intracellular oxidative stress and nuclear factor erythroid 2-related factor 2 (Nrf2) expression. Consequently, MUP promoted intracellular accumulation of DXR and significantly potentiated its cytotoxic effects in spheroids. Moreover, MUP enhanced the antitumor efficacy of other chemotherapeutic agent oxaliplatin. Sulforaphane, an Nrf2 activator, attenuated the MUP-induced enhancement of anticancer efficacy. These findings suggest that MUP enhances anticancer drug sensitivity in CRC through lysosome-dependent downregulation of CLDN14 protein and suppression of oxidative stress signaling."

Ferroptosis and mitochondrial biogenesis indicators were measured at various time points following MCAO. Various methods, including transmission electron microscopy, immunofluorescence assay, enzyme-linked immunosorbent assay, Western blotting assays, and real-time quantitative reverse transcription polymerase chain reaction (RT-qPCR), were employed to evaluate the impact of NTF on mitochondrial biogenesis and ferroptosis in vivo and in vitro. IS significantly inhibits mitochondrial biogenesis and increases neuronal ferroptosis, with brain damage worsening over time. MCAO groups showed reduced expression of Nrf2, TFAM, ATP, CISD2, FPN, GPX4, SOD, and HO-1, alongside elevated Fe\u00b2\u207a, ROS, and LPO (P < 0.05) compared to the control group.

This finding clarifies mitochondrial biogenesis's crucial role, proposes a new \"pathway + molecule\" strategy for IS treatment, and supports NTF's clinical potential, though larger animal models and long-term safety studies are needed. In the context of IS, reduced mitochondrial biogenesis plays an important role in ferroptosis. Targeting the Nrf2/TFAM signaling pathway may improve mitochondrial biogenesis in IS. Furthermore, NTF can mitigate ferroptosis by promoting mitochondrial biogenesis through the Nrf2/TFAM signaling pathway."

Currently, there are no specific medications available for ASD. Increasing attention is now focused on bioactive compounds with anti-inflammatory and antioxidant properties. Sulforaphane (SFN), a key member of the isothiocyanate family, is abundant in cruciferous vegetables. It exhibits potent antioxidant and anti-inflammatory effects with minimal side effects, while oxidative stress and inflammation are recognized triggers in ASD pathogenesis. As research deepens, SFN's physiological activities\u2500including antioxidant, neuroprotective, and anti-inflammatory properties are gaining heightened attention. Building on prior studies, this review comprehensively summarizes seven potential pathways through which SFN protects neurodevelopment or reverses ASD-related neural damage, including Keap1/Nrf2/ARE; MAPKs; NF-\u03baB; HSR; AhR/CYP1; Sirtuin-FOXO; and mTOR/autophagy signaling pathways, elucidating the potential mechanisms underlying its multifaceted actions.

Both compounds markedly impaired meiotic spindle assembly and compromised the function of multiple organelles, including mitochondria, the endoplasmic reticulum, and the Golgi apparatus, primarily through autophagy dysregulation at specific exposure concentrations, as evidenced by the observation that more than half of the oocytes failed to progress beyond the MII stage. Spermidine supplementation effectively restored autophagic activity and rescued the associated cellular defects, thereby improving both nuclear and cytoplasmic maturation in oocytes.

MARCH6 and FAM134B expression levels were measured in glioma tissues. A comparative analysis was conducted on the correlation between clinical parameters and FAM134B expression in 46 glioma patients. FAM134B and MARCH6 were knocked down in glioma cells, followed by detection of cell viability and apoptosis, typical ER stress (ERS) markers (PERK, IRE1\u03b1, eIF2\u03b1, and CHOP), autophagy-related proteins (P62 and LC3B), and autophagosome cytoplasmic accumulation. A mouse glioma model was established for in vivo validation. MARCH6-FAM134B interaction, FAM134B ubiquitination levels, and protein stability were examined. FAM134B expression was high and MARCH6 expression was low in glioma tissues. MARCH6 induced FAM134B protein ubiquitination and degradation, reducing its stability in glioma cells. Knockdown of FAM134B reduced glioma cell survival, inhibited PERK, IRE1\u03b1, eIF2\u03b1, and CHOP expression, decreased LC3I to LC3II conversion, lowered LC3B fluorescence expression, and reduced the accumulation of autophagosomes with continuous ER structures in the cytoplasm, while enhancing apoptosis and P62 expression. This effect can be reversed by knocking down MARCH6. In vivo, FAM134B knockdown suppressed tumorigenesis in mice. MARCH6 exerts a repressive effect on ERS responses and ER-phagy in glioma cells by destabilizing FAM134B."

Here, we identify FAM134B/RETREG1 as a specific ER-phagy receptor mediating amyloid precursor protein (APP) degradation. FAM134B directly interacts with ER-localized wild-type and familial mutant APP via their C-terminal domains and recruits LC3 through its LC3-interacting region (LIR) to promote APP delivery to phagophores for lysosomal degradation. In AD, epigenetic silencing at the FAM134B promoter suppresses its transcription by limiting TFEB/TFE3 binding despite their nuclear enrichment. This transcriptional suppression impairs ER-phagy, leading to APP accumulation and exacerbated AD pathology. AAV-mediated hippocampal expression of wild-type, but not LIR-mutant, FAM134B in 5XFAD mice restores ER-phagy, enhances APP clearance, reduces A\u03b2 deposition, preserves synaptic and myelin integrity, and improves cognitive performance. These findings establish FAM134B downregulation as an upstream pathogenic event in AD, suggesting ER-phagy enhancement as a promising strategy to suppress A\u03b2 generation at its source."

The evidence indicates that (1) dietary resistant starch increases butyrate production; (2) butyrate, sulforaphane, and spermidine independently activate Nrf2 and antioxidant defenses; (3) FAM134B-mediated ER-phagy is a mechanism for maintaining ER and cellular homeostasis; and (4) restoring astrocytic EAAT2 function is a critical strategy for mitigating glutamate excitotoxicity. While no single study describes this precise tripartite synergy, the individual components and pathways are well-documented as overlapping regulators of neuronal and glial survival in neurodegenerative models.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThis assessment synthesizes evidence regarding the modulation of redox homeostasis (via Nrf2), protein quality control (via ER-phagy), and glutamate uptake (via EAAT2). The proposed synergy between dietary butyrate, sulforaphane, and spermidine offers a novel, multi-target approach to neuroprotection by converging on these shared homeostatic nodes.\n\n### [INTRODUCTION & JUSTIFICATION]\nNeurodegenerative processes such as Alzheimer\u2019s and Parkinson\u2019s diseases are driven by convergent pathologies: oxidative stress, neuroinflammation, and glutamate excitotoxicity. Astrocytic EAAT2, the primary glutamate transporter, is frequently downregulated in these conditions, leading to synaptic glutamate accumulation and subsequent neuronal death. The literature demonstrates that dietary fiber/resistant starch promotes the production of SCFAs like butyrate, which serves as a major energy source for colonocytes and supports gut-brain axis homeostasis. Mechanistically, butyrate regulates Nrf2 and antioxidant pathways. Sulforaphane functions as a potent Nrf2 inducer, while spermidine enhances autophagic flux\u2014specifically FAM134B-mediated ER-phagy. Given that EAAT2 expression and membrane trafficking are susceptible to oxidative and ER stress, the combination of these agents potentially stabilizes the astrocytic proteome and redox environment, thereby preventing the collapse of glutamate buffering.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Butyrate and resistant starch are not merely metabolic fuels but active modulators of the gut-brain axis, impacting both Nrf2 signaling and microbiota composition.\n* FAM134B-mediated ER-phagy is emerging as a critical nexus for both viral restriction and cellular quality control in AD, with its downregulation serving as an early pathogenic event.\n* Spermidine does not only induce autophagy but also impacts hypusination of EIF5A, a process essential for regulating placental and potentially astrocytic protein synthesis.\n* Sulforaphane shows consistent photoprotective and neuroprotective effects, but its clinical utility remains constrained by variability in gut microbiome-mediated conversion.\n* T-2 toxin and cadmium toxicity share a common mechanism of suppressing FAM134B-mediated ER-phagy, linking environmental pollution to homeostatic decline.\n* Spermidine and sulforaphane independently stabilize mitochondrial and ER function, providing a combined metabolic and proteostatic shield for glial cells.\n* The cGAS-STING inflammatory axis is directly repressed by spermidine-mediated mitophagy, highlighting an immunological dimension to its neuroprotective profile.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Growing evidence shows that metabolites generated along the gut-brain axis regulate neuroinflammation. In this study, we demonstrate that oral administration of sodium butyrate (NaB) (300 or 600\u2009mg/kg/day) for 28 days lowered mortality and lessened neuropathological signs in mice infected with SS2 (SC19 strain). Butyrate prophylaxis was associated with lower bacterial loads in the blood and brain tissue, preserved expression of tight junction proteins (ZO-1, Claudin-5, and Occludin) in the brain, and maintained blood-brain barrier (BBB) integrity and permeability. 16S rRNA sequencing analysis revealed that SC19 infection significantly diminished the diversity and richness of the gut microbiota, notably depleting key short-chain fatty acid (SCFA)-producing bacterial taxa. Butyrate intervention restored microbial homeostasis and enriched SCFA-producing communities. Mechanistically, butyrate was associated with upregulated expression of nuclear factor erythroid 2-related factor 2 (Nrf2) and its downstream antioxidant effectors (heme oxygenase 1 [HO-1] and NQO1), while inhibiting phosphorylation of NF-\u03baB p65 and the secretion of proinflammatory cytokines (interleukin-1\u03b2 [IL-1\u03b2], interleukin-6 [IL-6], and tumor necrosis factor-\u03b1 [TNF-\u03b1]) in human cortical microvessels endothelial cells/D3 (hCMEC/D3) cells. Critically, these protective effects were abrogated upon pharmacological inhibition of Nrf2, indicating the critical role of Nrf2 in butyrate-mediated attenuation of neuroinflammation and oxidative stress.

Here, we identify FAM134B/RETREG1 as a specific ER-phagy receptor mediating amyloid precursor protein (APP) degradation. FAM134B directly interacts with ER-localized wild-type and familial mutant APP via their C-terminal domains and recruits LC3 through its LC3-interacting region (LIR) to promote APP delivery to phagophores for lysosomal degradation. In AD, epigenetic silencing at the FAM134B promoter suppresses its transcription by limiting TFEB/TFE3 binding despite their nuclear enrichment. This transcriptional suppression impairs ER-phagy, leading to APP accumulation and exacerbated AD pathology. AAV-mediated hippocampal expression of wild-type, but not LIR-mutant, FAM134B in 5XFAD mice restores ER-phagy, enhances APP clearance, reduces A\u03b2 deposition, preserves synaptic and myelin integrity, and improves cognitive performance. These findings establish FAM134B downregulation as an upstream pathogenic event in AD, suggesting ER-phagy enhancement as a promising strategy to suppress A\u03b2 generation at its source."

Current treatments offer limited efficacy, necessitating the development of innovative multitarget therapeutic strategies. Here, we present N3,N5-bis(2-(5-methoxy-1H-indol-3-yl)ethyl)-2,6-dimethyl-4-(2-nitrophenyl)pyridine-3,5-dicarboxamide (HCM-01), a novel compound developed to target multiple neurodegenerative pathways implicated in AD. In vitro assays included MTT-based cell viability analyses performed in two complementary experimental settings: primary neuronal cultures and astrocyte-based in vitro cell culture models exposed to glutamate. In primary hippocampal neuronal cultures, glutamate exposure induced a statistically significant reduction in cell viability compared with vehicle-treated controls, consistent with glutamate-induced excitotoxicity. Under these conditions, HCM-01 treatment resulted in a statistically significant improvement in neuronal viability, showing a greater protective effect compared with donepezil and memantine. In contrast, in astrocyte-based in vitro cultures, the applied glutamate concentration did not induce overt cytotoxicity, in line with the intrinsic neuroprotective and glutamate-buffering role of astrocytes. Accordingly, astrocytic experiments were designed to assess functional modulation of glutamate-handling mechanisms rather than cell survival. Western blot analysis in C8-D1A astrocytic cells demonstrated increased expression of excitatory amino acid transporter 2 (EAAT2) following HCM-01 treatment compared with control and reference drug-treated groups, suggesting modulation of astrocyte-mediated glutamate homeostasis. In parallel, redox analyses revealed that HCM-01 improved oxidative/antioxidative balance, as evidenced by increased total antioxidant capacity (TAC) and reduced total oxidant status (TOS), supporting an indirect antioxidant contribution to its functional effects. In vivo behavioral assessment of HCM-01 in a streptozotocin (STZ)-induced Alzheimer's model in female Sprague-Dawley rats demonstrated that administration of HCM-01 at doses of 50 mg/kg orally (oral, P.O. and intraperitoneal, I.P.) and 100 mg/kg (P.O.), significantly improved cognitive and memory functions in the passive avoidance (PA), Morris water maze (MWM), and locomotor activity tests. Moreover, histopathological and immunohistochemical analyses of different hippocampal regions revealed reduced neuronal damage, attenuation of tau pathology, antiamyloidogenic effect, and restoration of cholinergic function. Complementary in silico studies, including molecular docking, molecular dynamics simulations (MDS), and free energy calculations, suggested potential interactions of HCM-01 with the allosteric site of EAAT2. Taken together, these findings suggest that HCM-01 exerts neuroprotective effects against glutamate-induced excitotoxicity in primary hippocampal neurons while additionally modulating glutamatergic homeostasis and redox balance through functional mechanisms in astrocyte-based models, supporting its relevance as a multitarget preclinical candidate for early stage AD mechanisms."

This narrative review maps the adverse outcome pathways (AOPs) through which ethanol impairs synaptic function, primarily via interconnected cascades: TLR4/NF-\u03baB-mediated neuroinflammation (triggering microglial activation and pro-inflammatory cytokines TNF-\u03b1, IL-1\u03b2), CYP2E1-driven oxidative stress (generating ROS/RNS, 4-HNE, causing protein carbonylation and mitochondrial dysfunction), and glutamate excitotoxicity (mediated by GluN2B-NMDAR subunit shifts, Ca\u00b2\u207a overload, and astrocytic EAAT2/GLT-1 downregulation). These pathways converge to suppress BDNF/TrkB signaling (via miR-206 and impaired proBDNF cleavage), leading to deficits in synaptic protein synthesis (e.g., Arc) and trafficking (e.g., GluA1 endocytosis via STEP, impaired forward trafficking). Critically, these insults potentiate neuronal apoptosis through intrinsic (ROS/mitochondrial permeabilization, caspase-9/-3) and extrinsic (TNF-\u03b1/TNF-R1, caspase-8) pathways, executing irreversible synaptic loss via caspase-3 cleavage of PSD-95, spectrin, and cytoskeletal collapse. The structural consequences-dendritic simplification, reduced mature spine density, and PSD-95 nano-domain disorganization-manifest functionally as attenuated LTP, potentiated mGluR-LTD, and impaired STDP. This synaptic decay directly underpins cognitive impairments in pattern separation, contextual memory, and cognitive flexibility. Neuroinflammation (TLR4/NF-\u03baB) acts as a central amplifier, linking oxidative damage, excitotoxicity, and BDNF collapse to apoptotic synaptic deletion. Future research must address dose-dependency, subfield vulnerability, epigenetic regulation, and therapeutic strategies targeting TLR4, TrkB, mitochondrial antioxidants, and anti-apoptotic pathways."

Spermidine (SPD), a natural polyamine known to enhance autophagy and preserve cardiac function in aging and metabolic disorders, has not been systematically evaluated in the context of septic cardiomyopathy. To determine the therapeutic potential and mechanistic basis of SPD in septic cardiac dysfunction. Network pharmacology, RNA sequencing, a cecal ligation and puncture (CLP) mouse model, and multiple cellular assays were integrated to assess the protective actions of SPD. Mitochondrial function, mitophagy flux, and oxidative stress were evaluated using transmission electron microscopy (TEM), immunohistochemistry (IHC), Western blotting, structured illumination microscopy (SIM), mitochondrial membrane potential assays, oxygen consumption rate (OCR) analysis, and mitochondrial DNA (mtDNA) quantification. Transcriptomic clustering and pathway enrichment identified molecular targets, which were validated through siRNA-mediated gene silencing. SPD markedly attenuated SICM in vivo and in vitro by improving both mitochondrial quantity and quality. It restored sepsis-impaired mitophagy by upregulating LC3B and ATG7, promoting autophagosome maturation, and enhancing cellular ubiquitination. Transcriptomic profiling highlighted metallothionein-1 (MT1) as a key node in metal-ion response pathways. SPD activated the NRF2-MT1-SOD2 antioxidant axis, reduced mitochondrial reactive oxygen species (mtROS) under lipopolysaccharide (LPS) stimulation, and reversed sepsis-induced suppression of SOD2. MT1 knockdown abolished SPD-mediated SOD2 stabilization and mtROS clearance, confirming its essential role in SPD's cardioprotective effects. SPD mitigates SICM by orchestrating the restoration of mitochondrial quality control, normalization of mitophagic flux, and stabilization of cellular redox homeostasis. These findings support SPD as a promising therapeutic candidate for septic cardiomyopathy."

This study explores the interplay of endoplasmic reticulum stress (ERS), autophagy, and apoptosis in Cd-induced hepatotoxicity, focusing on whether ERS-driven autophagy protects against liver injury. Male SD rats (4\u202fweeks old, n\u202f=\u202f24) were acclimatized for 7\u202fdays and randomized into four groups receiving CdCl\u2082 at doses of 0, 0.5, 1, or 2\u202fmg/kg for 14 consecutive days. A second cohort (n\u202f=\u202f36) was similarly allocated to six groups: control, Cd, 4-PBA, Cd\u202f+\u202f4-PBA, CQ and Cd\u202f+\u202fCQ. All treatments were administered via daily intraperitoneal injection throughout the study. On day 14, blood and liver tissues were collected for analyses of liver function, hematological parameters, and histopathology. The expression of target factors was analyzed via qRT-PCR and Western blotting. Results indicate that Cd exposure causes liver injury and disordered hepatocyte morphology. ERS markers Grp78 and Caspase-12 and autophagy-related factors Beclin-1, Atg5, P62 and LC3 are upregulated at both mRNA and protein levels. The endoplasmic reticulum-phagy (ER-phagy) receptor FAM134B and the apoptosis effector cleaved Caspase3 are upregulated at the protein level. These findings indicate that Cd induces ERS, UPR activation, autophagy, reticulophagy, and apoptosis. The ERS inhibitor 4-PBA markedly attenuated Cd-induced hepatic injury. Compared with the Cd group, the Cd\u202f+\u202f4-PBA group showed decreased serum ALT and AST levels, as well as reduced RBC, WBC, MCH, and MCV counts. At the molecular level, mRNA and protein expression of ER stress markers Grp78, Caspase-12, PERK, eIF2\u03b1, ATF4, IRE1\u03b1, JNK, and ATF6 were all downregulated. Protein levels of the ER-phagy receptor FAM134B and the apoptosis effector cleaved Caspase-3 were also decreased. The autophagy inhibitor CQ aggravated such injury. Compared with the Cd group, the Cd\u202f+\u202fCQ group showed increased serum ALT and AST levels, as well as elevated RBC, MCH, and MCV counts. At the protein level, expression of the autophagy-related factors P62 and LC3, and the apoptosis effector cleaved Caspase-3 was significantly increased. These results show that Cd-induced ERS activates autophagy and reticulophagy mainly via the PERK, IRE1\u03b1, and ATF6 pathways, and this adaptive response clears autophagic substrates to alleviate hepatocyte damage."

Endoplasmic reticulum (ER) stress and autophagy are two interconnected stress responses critical for maintaining cellular homeostasis. Berbamine (BBM) is an important member of bis-benzy lisoquinoline alkaloid with diverse biological activities. This study aimed to identify the molecular target of BBM against T-2 toxin-induced hepatotoxicity, focusing on autophagy-ER stress crosstalk. We systematically evaluated autophagy and ER stress in human HepaRG cells using immunoblotting, transmission electron microscopy and an autophagy reporter assay. T-2 toxin was found to concurrently activate PINK1/Parkin-mediated mitophagy and suppress Keap1-mediated FAM134B ubiquitination-dependent ER-phagy, thereby triggering ER stress. Integrated evidence from molecular dynamics and western blot demonstrated that BBM upregulated and stabilized BNIP3, blocking the VAMP8-SNAP29 interaction to inhibit T-2 toxin-induced autophagy and subsequent ER stress. Moreover, in vivo mouse experiments demonstrated that 30\u202fmg/kg BBM significantly alleviated T-2 toxin-induced liver injury by suppressing both autophagic flux and ER stress; BBM significantly reduced serum levels of liver enzymes, ALT, and AST. Collectively, our findings elucidate a novel mechanism wherein T-2 toxin-induced mitophagy inhibits ER-phagy to drive ER stress-mediated liver injury and highlight the therapeutic potential of BBM in alleviating T-2 toxin-induced liver injury."

The mining of uranium and use of DU in modern weapons underly human exposure that disproportionally impacts military and tribal communities in the United States. Uranium's radiotoxic characteristics are understood, but its chemical hazards much less so. In zebrafish ( Danio rerio ) and human cell cultures we test the hypothesis that exposure to DU negatively impacts cellular function and development through disruption of mitochondrial metabolism. Using a novel shrapnel model with TEM/SEM+EDS, we showed uranium microparticles caused proximity-dependent mitochondrial disruption. In waterborne exposure paradigms, larval movement was reduced and hatching delayed as a result of reduced movement and not enzyme deficiencies in response to 18 ppb DU, below the MCL. Increased DNA damage accumulation was detected in exposed larva and cells. DNA-damage quantitative PCR of DU-exposed larvae showed increased damage in the ahr1 locus (nuclear gene) and decreased mitochondrial DNA (mtDNA) copy number, but mtDNA damage levels varied across experiments. Mitochondrial function was assessed using a resazurin-based assay in the presence and absence of antioxidants and showed diminished cytoplasmic reductive capacity. DU exposure alone did not enrich antioxidant gene expression, contrasting with arsenic exposure, a known ROS-inducer and Nrf2-activator. Sulforaphane (SFN), a potent Nrf2-activator, did not blunt the effects of DU exposure, despite activation of antioxidant response element (ARE) genes ( gstp and gss) , but did blunt the effects of arsenic exposure. The most enriched transcript in DU-exposed larvae coded for slingshot protein phosphatase ( ssh ), further exploration revealed ssh1b as the zebrafish-specific ortholog activated in response to DU, and inhibition using an identified SSH1 inhibitor, Sennoside A, partially rescued the metabolic and hatching defects observed. Our data points to a cytotoxic mechanism in which DU disrupts mitochondrial function through ssh1b enrichment that impairs normal mitophagy, leading to decreased cellular reductive potential independent of either ROS production or ARE-activation. Our results suggest that health impacts from DU exposure may be directly linked to impaired mitochondrial functions."

To address this question, we investigated a monogenic form of epilepsy (pyridoxine-dependent epilepsy) caused by aldehyde dehydrogenase 7 family member A1 (ALDH7A1) mutations. ALDH7A1 global knockout mice exhibited both seizure-associated and maladaptive affective behavioral phenotypes. However, seizure phenotypes were caused by ALDH7A1 deletion in hepatocytes whereas maladaptive affective behaviors were caused by ALDH7A1 deletion in astrocytes. Deletion in astrocytes disrupted astrocyte redox homeostasis, impairing regulation of extracellular ion concentrations and reducing neuronal activity in the prelimbic cortex. Sulforaphane, which activates the NRF2 antioxidant pathway, restored prelimbic neuronal activity and rescued maladaptive affective behaviors in ALDH7A1 knockout mice but did not prevent seizures. These studies implicate astrocyte redox homeostasis and prelimbic hypoactivity in maladaptive affective behavioral phenotypes in a congenital form of epilepsy, which are mechanistically and therapeutically dissociable from seizure pathophysiology."

Codonopsis pilosula is the sovereign herb in Shenling Baizhu Formula for ulcerative colitis therapy, and Codonopsis pilosula polysaccharides are its key active components, while their immunomodulatory effects and molecular mechanisms in Shenling Baizhu Formula against ulcerative colitis remain elusive. This study explored the critical role of Codonopsis pilosula polysaccharides and the spermidine-AMPK-mediated mitophagy-cGAS-STING inflammatory axis in regulating intestinal inflammation and ameliorating ulcerative colitis. A dextran sulfate sodium-induced ulcerative colitis mouse model was established to evaluate the indispensable role of Codonopsis pilosula polysaccharides in Shenling Baizhu Formula. Ultra-high performance liquid chromatography metabolomics and 16S ribosomal RNA sequencing were performed to identify key metabolites and gut microbiota. In vitro dextran sulfate sodium-induced ulcerative colitis cellular models (human colorectal adenocarcinoma Caco-2 and human normal colonic epithelial NCM460 cells) were constructed to validate the regulatory mechanism of spermidine on AMPK-mediated mitophagy, inflammatory balance and intestinal epithelial injury. Codonopsis pilosula polysaccharides were essential for the anti-ulcerative colitis efficacy of Shenling Baizhu Formula: removal of Codonopsis pilosula significantly aggravated colonic pathological lesions, intestinal inflammatory responses and oxidative stress in ulcerative colitis mice, whereas Codonopsis pilosula polysaccharides supplementation reversed these abnormal phenotypes (P\u00a0<\u00a00.05). Metabolomics and microbiomics confirmed that Codonopsis pilosula polysaccharides exerted therapeutic effects via spermidine (a key metabolite in glutamate metabolism pathway) and Muribaculaceae. Critically, in vitro dual-cell experiments verified that spermidine activated AMPK-mediated mitophagy to directly inhibit the hyperactivation of cGAS-STING inflammatory axis, thereby restoring intestinal inflammatory homeostasis and alleviating epithelial cell injury in ulcerative colitis. Codonopsis pilosula polysaccharides extracted from the sovereign herb Codonopsis pilosula in Shenling Baizhu Formula ameliorate dextran sulfate sodium-induced ulcerative colitis, and the core mechanism depends on spermidine-triggered AMPK-mediated mitophagy to suppress the cGAS-STING inflammatory signaling axis, which plays a pivotal role in regulating intestinal immunity and repairing mucosal epithelial damage."

Here, we identify the vitamin D receptor (Vdr) as a key anti-aging transcription factor whose expression in granulosa cells (GCs) declines with age. Using GCs-specific Vdr knockout (cVKO) mice and a Vdr-knockout (VKO) human granulosa-like cell line, we demonstrate that loss of Vdr triggers GCs aging and disrupts ovarian function. Integrated transcriptomic and metabolomic analyses from VKO and WT cells revealed that Vdr loss downregulates the de novo spermidine (SPD) biosynthesis by directly suppressing the transcription of ornithine decarboxylase (ODC1). This led to SPD depletion, which in turn inhibited DNA methyltransferase (DNMTs) activity, resulting in hypomethylation of the p53 promoter and activation of the p53/p21 pathway. Crucially, supplementation with either SPD or its upstream methyl donor S-adenosylmethionine (SAM) rescued cVKO and VKO cell aging, improved hormonal profiles and promoted follicular development in cVKO mice. Furthermore, both supplements effectively delayed ovarian aging and improved fertility in naturally aged mice. Our study unveils the Vdr-spermidine-DNMTs axis as a fundamental mechanism safeguarding against ovarian aging, highlighting SPD and SAM as promising therapeutic agents for age-related female infertility."

This study investigates the neuroprotective potential of Sulforaphane (SFN) in ameliorating ethidium bromide (EBRM)-induced MS-like pathology in Wistar rats. The efficacy of SFN at two doses (SFN1.5 and SFN3) was compared to FDA-approved Nrf2 activator drugs, omaveloxolone (OMV15) and dimethyl fumarate (DIMF50). EBRM administration caused neurobehavioral deficits, demyelination, oxidative stress, axonal degeneration, and inflammation. It disrupted key cellular pathways, including Nrf2/HO-1/SIRT-1, JAK/STAT-3/mTOR, and BACE-1/Gamma-secretase/MAPT, as well as caused neurotransmitter imbalances. SFN3 demonstrated significant improvement in motor function, cognitive performance, neurotransmitter levels antioxidant enzymes and alleviated neuroinflammation by modulating inflammatory cytokines. Molecular analyses showed that SFN3 increased Nrf2/HO-1/SIRT-1 levels while decreased pro-inflammatory and neurodegenerative markers such as STAT-3, mTOR, and BACE-1 levels. Gross pathological, Histopathological, and LFB studies indicated reduced demyelination and liver damage. SFN3 also demonstrated favourable systemic safety compared to OMV15. While DIMF50 showed the highest overall efficacy, SFN3 showed consistent modulation of pathological markers, neuroprotective effects, and safety profile. These findings suggest that SFN3 may have therapeutic potential for further translational research in MS. Future studies should validate its clinical relevance and explore combinatorial therapies with existing MS treatments to enhance therapeutic outcomes."

Here, we examined the effects of two haloacetamides, 2,2-dichloroacetamide (DCAcAm) and 2,2-dibromoacetamide (DBAcAm), on mouse oocyte maturation and identified the underlying mechanisms of toxicity. Both compounds markedly impaired meiotic spindle assembly and compromised the function of multiple organelles, including mitochondria, the endoplasmic reticulum, and the Golgi apparatus, primarily through autophagy dysregulation at specific exposure concentrations, as evidenced by the observation that more than half of the oocytes failed to progress beyond the MII stage. Spermidine supplementation effectively restored autophagic activity and rescued the associated cellular defects, thereby improving both nuclear and cytoplasmic maturation in oocytes. Collectively, these findings demonstrate that spermidine alleviates toxicant-induced deterioration of oocyte quality by regulating autophagy and highlight its potential therapeutic value for reproductive protection and clinical application."

Here, using state-of-the-art super-resolution multi-SIM imaging, we reveal that stresses (prolonged starvation, cholesterol dyshomeostasis, and high-Ca2+ insults) trigger the expansion of sheet ER subdomains containing high levels of luminal Ca2+ in mammalian cells, which are subsequently degraded by ER-phagy. Autophagosome formation and sequestration of ER sheets require the concerted actions of FAM134B and lipidated LC3, whereas the autophagy proteins ATG14 and ATG9 are partially dispensable. Electron microscopy and cryo-electron tomography show that the membranes of autophagosomes enclosing high-Ca2+-containing ER sheets are directly remodeled from the ER. The ER-localized cation channels PIEZO1 and TRPV1 are enriched at and mediate Ca2+ transients from high-Ca2+-containing ER sheets, triggering liquid-liquid phase separation of the autophagosome-initiating FIP200 complex to initiate ER-phagy. Thus, distinct mechanisms are employed for the formation of high-Ca2+-containing ER-enclosing autophagosomes and non-selective autophagosomes."

Alginate oligosaccharide (AOS), a marine-derived bioactive polysaccharide, exhibits prebiotic, anti-inflammatory and antioxidant properties that are effective against various inflammatory diseases. In this study, a mouse model of SAP was established by intraperitoneal injection of cerulein (100 \u03bcg/kg) and lipopolysaccharide (5 mg/kg), and the mice were pretreated with AOS (200 mg/kg) by gavage for 4 consecutive weeks to explore the potential protective efficacy and underlying mechanisms. The results shown that AOS attenuated the severity of SAP, as evidenced by reduced serum amylase and lipase levels, as well as alleviated histopathological injury in both pancreatic and ileal tissues. AOS suppressed the overproduction of pro-inflammatory cytokines (IL-1\u03b2, IL-6, TNF-\u03b1) in serum, pancreas, and ileum at protein or mRNA levels. Moreover, AOS effectively diminished pancreatic and ileal inflammatory infiltration and oxidative stress in SAP mice, accompanied by inhibited the TLR4/MyD88/NF-\u03baB pathway and activated the Nrf2/HO-1 antioxidant axis. Furthermore, AOS restored intestinal barrier integrity, as manifested by upregulated expression of tight junction proteins (claudin-1, occludin, ZO-1), reduced serum diamine oxidase, and decreased bacterial translocation from the gut to the pancreas. It was revealed by 16S rRNA sequencing that AOS ameliorated SAP-induced gut dysbiosis by restoring microbial diversity, normalizing the Firmicutes/Bacteroidetes ratio, enriching beneficial genera (Lactobacillus, Blautia), and enhancing cecal short-chain fatty acid (acetic, propionic, butyric acid) production. Collectively, our findings demonstrate that AOS exerts comprehensive protective effects against SAP through suppression of inflammatory signaling and oxidative stress, as well as restoring gut homeostasis. These results suggest that AOS may serve as a promising prebiotic-based nutritional strategy for the management of SAP."

Spermidine has been shown to counteract immunosenescence and induce autophagy in preclinical models, and its levels decline with age in humans. We conducted a double-blind, randomised, placebo-controlled pilot study in 40 adults over 65\u2009years of age following their third SARS-CoV-2 vaccine dose to assess the safety of Spermidine and its effects on vaccine-induced immunity. Daily oral supplementation (6\u2009mg, 13\u2009weeks) was well-tolerated. Vaccine non-responsiveness was common, and non-responders exhibited a distinct immune-senescence signature marked by elevated p16, mTOR signalling, and \u03b3-H2AX+ DNA damage in lymphocytes. Spermidine reversed these features and significantly enhanced spike-specific IgG secretion, memory B cell recall responses and neutralising antibody activity, specifically in non-responders. Single-cell RNA-seq after treatment revealed increased expression of TFEB targets and autophagy-related genes in B cells, in line with elevated autophagic flux. These findings suggest that targeting immune cell senescence with Spermidine may improve vaccine responsiveness in older adults and highlight immune-senescence markers as potential predictors of vaccine failure in ageing populations."

To our knowledge, no prior systematic review has synthesized evidence linking these metabolites to direct mitochondrial endpoints across all major metabolite classes. PubMed, Scopus, and Web of Science were systematically searched through March 2026 for studies examining direct mitochondrial endpoints in relation to ten classes of gut-derived metabolites. Gut-derived microbial metabolites exert diverse effects on mitochondrial function, ranging from bioenergetic enhancement to direct toxicity. After contextual evidence was excluded from the certainty assessment, four metabolite-mitochondrial outcome groupings had moderate certainty: butyrate, propionate, indoxyl sulfate, and lipopolysaccharide. Evidence for p-cresyl sulfate, H\u2082S, and urolithin A was rated low; evidence for the remaining metabolite classes was low or very low. Butyrate generally enhances mitochondrial biogenesis, ATP generation, and electron transport chain activity across multiple experimental models. Indoxyl sulfate generally impaired mitochondrial function, whereas p-cresyl sulfate produced concentration- and model-dependent effects. PGC-1\u03b1 emerges as a central regulatory node, integrating microbial metabolic signals to control mitochondrial biogenesis and oxidative metabolism. Many microbial metabolites demonstrate concentration-dependent biphasic effects. These findings support a mechanistic microbiome-mitochondrial framework in which diverse gut-derived molecules converge on a limited set of mitochondrial control nodes: electron transport chain activity, reactive oxygen species handling, biogenesis, and mitophagy. The evidence base is predominantly preclinical; these insights should be considered hypothesis-generating."

Polyamines, including putrescine, spermidine, and spermine, are vital microbial-host metabolites that support intestinal cell growth, autophagy, immune modulation, and mucosal repair. With advancing age, both host-derived and microbiota-mediated polyamine production declines, contributing to intestinal dysfunction and heightened vulnerability to inflammation and age-related disorders. This review explores the diet-microbiota-polyamine axis as a key biological framework influencing intestinal aging. It aims to integrate evidence on how dietary components and functional foods shape gut microbial ecology and, in turn, regulate microbial polyamine biosynthetic pathways that impact intestinal health. The review highlights major microbial contributors to polyamine metabolism, particularly lactic acid bacteria, and outlines mechanistic pathways linking polyamines to epithelial regeneration, inflammatory control, and gut barrier maintenance. It further discusses how age-associated dysbiosis disrupts these interactions and evaluates nutritional and microbial-based strategies such as fermented foods, prebiotics, and probiotics that may enhance polyamine availability and restore gut homeostasis. From the standpoint of food microbiology and human physiology, this synthesis underscores the translational potential of targeting microbial polyamine production through diet-based interventions. This article presents a narrative review synthesizing experimental, animal, and emerging human evidence on microbial and dietary polyamines in intestinal aging. In conclusion, modulating the diet-microbiota-polyamine axis represents a promising strategy to promote healthy intestinal aging, meriting deeper mechanistic exploration and validation through clinical studies."

Here, we found that SS-31 supplementation efficaciously improved oocyte maturation and early embryonic development from aged mice. Specifically, SS-31 remarkably restored the normal spindle/chromosome structure, fertilization ability, mitochondrial distribution, \u0394\u03a8m and mitophagy in aged oocytes. In contrast, SS-31 reduced oocyte aneuploidy, ROS accumulation and DNA damage. Mechanistically, single-cell transcriptome analysis reveals that SS-31 increased the maternal mRNA degradation, and the levels of genes associated with mitochondrial function and mitophagy in aged oocytes, such as Pink1, Rps27a, Tomm7 and Map1lc3b. In addition, SS-31 suppressed chromatin organization, histone modification and chromatin remodeling pathways. Moreover, we applied the single-cell untargeted metabolomics to identify that SS-31 increased the levels of spermidine and GSH, which were critical metabolites to protect oocytes against aging. Our data reveal that the beneficial effect of SS-31 on oocyte quality from advanced age is mainly mediated by restoration of mitochondrial function, mitophagy and anti-aging metabolites. It provides a potential strategy for improving oocyte quality to extend the reproductive lifespan of female animals."

Here, we identify ER-phagy as a previously unrecognized adaptive response to ISOXUS, an isoxazole derivative of usnic acid with selective anticancer activity. ISOXUS, a mitochondrial respiratory complex II inhibitor, induces bioenergetic collapse, reactive oxygen species accumulation, and extensive ER-derived vacuolization. Using integrated transcriptomic and metabolomic analyses, we demonstrate that ISOXUS selectively triggers ER-phagy in mitochondria-dependent MCF-7 breast cancer cells, but not in more glycolytic triple-negative MDA-MB-231 cells, revealing a cell-type-specific stress adaptation program. ER-phagy induction is associated with upregulation of the ER-phagy receptor FAM134B and depends on ER stress signalling, as pharmacological ER stress inhibition suppresses this process. Multi-omics profiling uncovers coordinated repression of mitochondrial gene expression together with activation of ER-centered metabolic pathways, including amino acid metabolism, the tricarboxylic acid cycle, and one-carbon folate metabolism. Notably, we also identify UFMylation-related genes (CDK5RAP3, DDRGK1) as novel candidates involved in ER-phagy induced by ISOXUS. Moreover, mitochondrial inhibitors, rotenone and oligomycin, unexpectedly promote, while antioxidant a-tocopherol blocks ISOXUS-induced ER-phagy, and all compounds partially improve cell viability under ISOXUS treatment, implicating ROS-driven ER-phagy as a cytoprotective mechanism. Integrated analyses further reveal activation of the integrated stress response (ISR), dominated by the PERK-ATF4 axis, driving glutamine-dependent metabolic reprogramming and suppression of apoptosis-related pathways. The late-stage autophagy inhibition lowered the glutathione synthesis after ISOXUS treatment. Collectively, our findings uncover a previously unappreciated mitochondria-ER-ISR axis that governs metabolic adaptation to ISOXUS and identifies ER-phagy as a potential therapeutic vulnerability in breast cancer."

Spermidine (SPD), a natural polyamine known to enhance autophagy and preserve cardiac function in aging and metabolic disorders, has not been systematically evaluated in the context of septic cardiomyopathy. To determine the therapeutic potential and mechanistic basis of SPD in septic cardiac dysfunction. Network pharmacology, RNA sequencing, a cecal ligation and puncture (CLP) mouse model, and multiple cellular assays were integrated to assess the protective actions of SPD. Mitochondrial function, mitophagy flux, and oxidative stress were evaluated using transmission electron microscopy (TEM), immunohistochemistry (IHC), Western blotting, structured illumination microscopy (SIM), mitochondrial membrane potential assays, oxygen consumption rate (OCR) analysis, and mitochondrial DNA (mtDNA) quantification. Transcriptomic clustering and pathway enrichment identified molecular targets, which were validated through siRNA-mediated gene silencing. SPD markedly attenuated SICM in vivo and in vitro by improving both mitochondrial quantity and quality. It restored sepsis-impaired mitophagy by upregulating LC3B and ATG7, promoting autophagosome maturation, and enhancing cellular ubiquitination. Transcriptomic profiling highlighted metallothionein-1 (MT1) as a key node in metal-ion response pathways. SPD activated the NRF2-MT1-SOD2 antioxidant axis, reduced mitochondrial reactive oxygen species (mtROS) under lipopolysaccharide (LPS) stimulation, and reversed sepsis-induced suppression of SOD2. MT1 knockdown abolished SPD-mediated SOD2 stabilization and mtROS clearance, confirming its essential role in SPD's cardioprotective effects. SPD mitigates SICM by orchestrating the restoration of mitochondrial quality control, normalization of mitophagic flux, and stabilization of cellular redox homeostasis. These findings support SPD as a promising therapeutic candidate for septic cardiomyopathy."

As an important carbohydrate, starch directly affects the homeostasis of glucose and lipid metabolism due to its digestion characteristics. Resistant starch (RS) with unique anti-digestive properties and prebiotic functions has become the current hotspot in dietary nutrition research for improving glucose and lipid metabolism disorders. This review summarizes the digestive characteristics of starch and the comprehensive effects of RS and its mechanisms for ameliorating metabolic diseases. Diets with high RS content not only optimize glucose homeostasis by delaying glucose release, the undigested fractions entering the colon also drive the metabolic regulatory network of the gut microbiota-gut-brain axis by activating the AMPK/ACC pathway to reduce fat accumulation, enhancing intestinal barrier function mediated by short-chain fatty acids (SCFAs), and promoting GLP-1/PYY neural signal transduction. These insights facilitate the design of new healthy foods and inspire new strategies for optimizing dietary nutrition and regulating glucose and lipid metabolism disorders caused by high-carbohydrate diets. \u4ee3\u8c22\u6027\u75be\u75c5\u5982\u80a5\u80d6\u3001\u7cd6\u5c3f\u75c5\u3001\u5fc3\u8840\u7ba1\u75be\u75c5\u7684\u5168\u7403\u6d41\u884c\u4e0e\u8425\u517b\u8fc7\u5269\u53ca\u996e\u98df\u6a21\u5f0f\u5931\u8861\u5bc6\u5207\u76f8\u5173\u3002\u6dc0\u7c89\u4f5c\u4e3a\u4eba\u7c7b\u4e3b\u8981\u80fd\u91cf\u6765\u6e90\u7684\u78b3\u6c34\u5316\u5408\u7269\uff0c\u5176\u6d88\u5316\u7279\u6027\u76f4\u63a5\u5f71\u54cd\u7cd6\u8102\u4ee3\u8c22\u7a33\u6001\u3002\u6297\u6d88\u5316\u6027\u6dc0\u7c89\uff08RS\uff09\u56e0\u5176\u72ec\u7279\u7684\u6297\u6d88\u5316\u7279\u6027\u4e0e\u76ca\u751f\u5143\u529f\u80fd\uff0c\u6210\u4e3a\u5f53\u524d\u6539\u5584\u7cd6\u8102\u4ee3\u8c22\u7d0a\u4e71\u7684\u81b3\u98df\u8425\u517b\u7814\u7a76\u7684\u70ed\u70b9\u3002\u672c\u6587\u7efc\u8ff0\u4e86\u6dc0\u7c89\u6d88\u5316\u7279\u6027\u4ee5\u53caRS\u6539\u5584\u4ee3\u8c22\u6027\u75be\u75c5\u7684\u7efc\u5408\u4f5c\u7528\u53ca\u76f8\u5173\u673a\u5236\u3002\u9ad8RS\u7684\u81b3\u98df\u4e0d\u4ec5\u901a\u8fc7\u5ef6\u7f13\u8461\u8404\u7cd6\u91ca\u653e\u4f18\u5316\u8840\u7cd6\u7a33\u6001\uff0c\u800c\u4e14\u672a\u6d88\u5316\u7684\u90e8\u5206\u8fdb\u5165\u7ed3\u80a0\u901a\u8fc7\u9a71\u52a8\u80a0\u9053\u83cc\u7fa4-\u80a0-\u8111\u8f74\u4ee3\u8c22\u8c03\u63a7\u7f51\u7edc\uff0c\u5176\u4e2d\u5305\u62ec\u6fc0\u6d3b\u817a\u82f7\u9178\u6d3b\u5316\u86cb\u767d\u6fc0\u9176/\u4e59\u9170\u8f85\u9176A\u7fa7\u5316\u9176\uff08AMPK/ACC\uff09\u901a\u8def\u51cf\u5c11\u8102\u80aa\u84c4\u79ef\u3001\u63d0\u5347\u77ed\u94fe\u8102\u80aa\u9178\uff08SCFAs\uff09\u4ecb\u5bfc\u7684\u80a0\u5c4f\u969c\u529f\u80fd\u4e0e\u80f0\u9ad8\u8840\u7cd6\u7d20\u6837\u80bd-1/\u80bdYY\uff08GLP-1/PYY\uff09\u795e\u7ecf\u4fe1\u53f7\u4f20\u5bfc\u3002\u8fd9\u4e0d\u4ec5\u5c06\u4e3a\u65b0\u578b\u5065\u5eb7\u98df\u54c1\u8bbe\u8ba1\u63d0\u4f9b\u7814\u7a76\u57fa\u7840\uff0c\u4e5f\u4e3a\u4f18\u5316\u81b3\u98df\u8425\u517b\uff0c\u8c03\u63a7\u9ad8\u78b3\u6c34\u996e\u98df\u5f15\u8d77\u7684\u7cd6\u8102\u4ee3\u8c22\u7d0a\u4e71\u63d0\u4f9b\u4e86\u65b0\u7684\u7814\u7a76\u601d\u8def\u3002."

Although PFOS exposure causes significant bioaccumulation and potential myelotoxicity, its specific impact on the chondrogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) remains to be elucidated. In this study, we established a murine model of PFOS exposure to isolate primary BMSCs and investigated this issue through in vitro differentiation assays, cellular senescence evaluations, and an in vivo subcutaneous implantation model using gelatin methacryloyl (GelMA) hydrogel scaffolds. Our results demonstrated that PFOS exposure triggered intracellular reactive oxygen species (ROS) accumulation and induced a senescent phenotype in BMSCs, characterized by restricted cellular proliferation and the release of senescence-associated secretory phenotype (SASP) factors, thereby markedly suppressing their chondrogenic capacity. Mechanistically, the inhibition of the Nrf2 signaling pathway by PFOS was identified as the principal driver of this process. Furthermore, both in vitro and in vivo assays confirmed that pharmacological activation using the Nrf2 agonist sulforaphane (SFN) effectively mitigated the senescent phenotype and restored the chondrogenic potential of PFOS-exposed BMSCs. Altogether, these findings elucidate the specific mechanisms of PFOS-induced stem cell toxicity and offer a potential strategy to overcome the resulting limitations in BMSC-based cartilage regeneration."

PACS2, a key resident protein at mitochondria-associated endoplasmic reticulum membranes (MAMs), regulates ER homeostasis under various pathological conditions. However, whether sepsis disrupts PACS2-dependent MAM integrity, thereby triggering ER dysfunction and muscle wasting, remains unexplored. We established a sepsis mouse model via cecal ligation and puncture (CLP) and assessed muscle function using compound muscle action potential (CMAP) recording and grip strength measurements. Muscle atrophy was evaluated by H&E staining and Western blotting. PACS2 expression was determined by Western blotting, immunohistochemistry and qRT-PCR. MAM integrity was assessed by immunofluorescence co-localization of IP3R and VDAC1, and ER-phagy (reticulophagy) activation was evaluated by transmission electron microscopy, Western blotting and fluorescence microscopy. To investigate the functional role of PACS2, adeno-associated virus (AAV)-mediated PACS2 overexpression was performed in mouse tibialis anterior muscle and gastrocnemius muscles, followed by RNA-sequencing analysis. The MAPK pathway proteins p-ERK, p-P38 and p-JNK levels were assessed by Western blotting, and the involvement of ERK-MAPK signalling was tested pharmacologically via intraperitoneal injection of the ERK inhibitor SCH772984. Septic mice developed progressive skeletal muscle atrophy (p\u2009<\u20090.001) and dysfunction (p\u2009<\u20090.01), accompanied by 56% reduction in PACS2 expression at 96\u2009h post-CLP (p\u2009<\u20090.01), 25% decrease in MAM integrity (p\u2009<\u20090.05) and subsequent activation of FAM134B-mediated ER-phagy (p\u2009<\u20090.01). AAV-mediated PACS2 overexpression significantly alleviated muscle atrophy by restoring MAM integrity by 28% (p\u2009<\u20090.01), reducing FAM134B expression by 43% (p\u2009<\u20090.01) and attenuating ER-phagy (p\u2009<\u20090.01).

Transcriptome sequencing and Western blotting analysis demonstrated that PACS2 overexpression specifically activated the ERK-MAPK signalling pathway (55% increase in p-ERK, p\u2009<\u20090.01) without affecting p-P38 or p-JNK levels (p>0.05), which suppressed FAM134B-mediated ER-phagy (p\u2009<\u20090.05) and ameliorated muscle atrophy (p\u2009<\u20090.05) by inhibiting nuclear translocation of TFEB (p\u2009<\u20090.01). Pharmacological ERK inhibition with SCH772984 abolished the protective effects of PACS2 by promoting TFEB nuclear translocation (p\u2009<\u20090.001) and TFEB-mediated FAM134B expression (p\u2009<\u20090.001). Our findings demonstrate that SIM is closely associated with disrupted MAM integrity. PACS2 plays a critical role in maintaining MAM structural integrity and regulating FAM134B-mediated ER-phagy through the ERK-MAPK-TFEB signalling axis, thereby providing novel mechanistic insights and potential therapeutic targets for SIM."

To address this question, we investigated a monogenic form of epilepsy (pyridoxine-dependent epilepsy) caused by aldehyde dehydrogenase 7 family member A1 (ALDH7A1) mutations. ALDH7A1 global knockout mice exhibited both seizure-associated and maladaptive affective behavioral phenotypes. However, seizure phenotypes were caused by ALDH7A1 deletion in hepatocytes whereas maladaptive affective behaviors were caused by ALDH7A1 deletion in astrocytes. Deletion in astrocytes disrupted astrocyte redox homeostasis, impairing regulation of extracellular ion concentrations and reducing neuronal activity in the prelimbic cortex. Sulforaphane, which activates the NRF2 antioxidant pathway, restored prelimbic neuronal activity and rescued maladaptive affective behaviors in ALDH7A1 knockout mice but did not prevent seizures. These studies implicate astrocyte redox homeostasis and prelimbic hypoactivity in maladaptive affective behavioral phenotypes in a congenital form of epilepsy, which are mechanistically and therapeutically dissociable from seizure pathophysiology."

ZEN exposure induces endoplasmic reticulum (ER) stress, oxidative stress, and autophagy activation. However, the involvement of inositol-requiring enzyme 1 (IRE1)-mediated ER-phagy in ZEN-induced ER stress and embryonic competence during in vitro culture (IVC) remains unclear. Porcine embryos were cultured with 2.5, 5, and 10\u202f\u03bcM ZEN for two days after in vitro fertilization (IVF) to assess blastocyst development. ZEN exposure caused a significant dose-dependent decrease in blastocyst formation, expanded blastocysts, and total cell number (p\u202f<\u202f0.05). ZEN-treated embryos exhibited increased DNA fragmentation along with elevated mitochondrial and intracellular Ca\u00b2\u207a levels (p\u202f<\u202f0.001), as confirmed using terminal deoxynucleotidyl transferase dUTP nick-end labeling assay and Rhod-2 and Fluo-4 AM staining. ER-tracker analysis revealed decreased ER fluorescence intensity and increased uneven cytoplasmic ER distribution in blastocysts exposed to 5 and 10\u202f\u03bcM ZEN (p\u202f<\u202f0.001). Western blotting showed activation of the unfolded protein response (UPR) with increased expression of glucose-regulated protein 78 (GRP78), p-IRE1, IRE1, p-c-Jun N-terminal kinase (JNK), JNK, C/EBP homologous protein (CHOP), and the autophagy marker microtubule-associated protein 1 light chain 3 beta (LC3B) (p\u202f<\u202f0.05), whereas the ER-phagy receptor family with sequence similarity 134, member B was downregulated. Tauroursodeoxycholic acid (TUDCA) alleviated ZEN-induced ER stress, restoring ER distribution and calcium homeostasis, reducing DNA damage, and improving blastocyst development. These findings suggest that ZEN disrupts IRE1 signaling and suppresses ER-phagy during early porcine embryo development, whereas TUDCA alleviates ER stress and improves embryonic competence during IVC."

The identification of specific ER-phagy receptors including FAM134A, FAM134B, FAM134C, TEX264, SEC62, RTN3L, CCPG1, ATL3, CALCOCO1 and others has significantly advanced our understanding of ER quality control mechanisms. In this review we summarize the current knowledge on ER-phagy receptors, and emerging evidence linking ER-phagy dysfunction to various disease pathologies including neurological disorders, cancer, metabolic diseases, cardiovascular diseases, infections and immune disorders. Recent evidence shows that ER-phagy receptors can form novel ER-derived structures, such as ER-tubular bodies (ER-TBs) consisted of ATL3 and RTN3L, which mediate Golgi-bypassing unconventional protein secretion under stress conditions, revealing non-degradative functions of these receptors beyond quality control. Targeting ER-phagy receptors may provide insights into potential therapeutic strategies for diseases associated with this fundamental cellular process."

In a total lung irradiation (TLI) mouse model, FMT significantly alleviated pulmonary histopathological injury, inflammatory responses, oxidative stress, and collagen deposition during fibrogenesis. Concurrently, FMT improved intestinal motility, enhanced mucosal barrier integrity, and restored TLI-induced dysbiosis in gut microbiota diversity and community structure. Metabolomic analysis revealed that TLI significantly disrupted the metabolism of unsaturated fatty acids and arachidonic acid (AA), whereas FMT partially restored these metabolic networks.

"abstract_text": "ID: 42197044\nTitle: Dietary Polyamine Intake Across Age Groups in Spain: A Comprehensive Assessment.\nAbstract: Polyamines, including putrescine (PU), spermidine (SPD), and spermine (SPM), are ubiquitous bioactive compounds essential for cell proliferation, genomic stability, autophagy, and the regulation of oxidative and inflammatory responses. Growing evidence, particularly for SPD, suggests that polyamine-rich diets may protect against age-related conditions such as cardiovascular disease, metabolic syndrome, and neurodegenerative disorders. As endogenous polyamine synthesis declines with age, dietary intake becomes increasingly important, especially in older adults. This study estimated each polyamine (PU, SPD and SPM) and total polyamine intake in the Spanish population using food consumption data from the Spanish Ministry of Agriculture, Fisheries and Food. Intakes were evaluated across four age groups, and major dietary sources were identified. Total polyamine intake increased with age, reaching 393 \u00b5mol/day in adults over 65 years. PU accounted for 49% of total intake, followed by SPD (29%) and SPM (22%). Plant-based foods were the primary contributors to SPD intake, particularly vegetables (36%), fruits (26%), and cereals (18%). PU intake was also predominantly plant-derived, mainly from fruits (58%) and vegetables (23%), whereas SPM intake was largely associated with meat products (59%). A theoretical Mediterranean diet model yielded a slightly higher total polyamine intake of 406.6 \u00b5mol/day and a substantially greater SPD intake than that observed in older adults (193.99 \u00b5mol/day versus 121.62 \u00b5mol/day). Overall, estimated polyamine intake in the Spanish population fell below the optimal level of 540 \u00b5mol/day proposed in the literature. These findings highlight the need for public health strategies promoting consumption of polyamine-rich foods, particularly vegetables, legumes, whole grains, and fruits, to support healthy aging and reduce the risk of age-related diseases."

The nuclear factor erythroid 2-related factor 2 (Nrf2) pathway plays a central role in regulating cellular antioxidant defences against UV-induced damage. This scoping review aims to evaluate the potential role of sulforaphane (SFN), a known Nrf2 inducer, in protecting against UV-induced skin damage and photocarcinogenesis. Methods: A literature search was conducted in PubMed and Scopus from inception to 27 January 2026, to identify original experimental studies investigating SFN, glucoraphanin, or broccoli sprout extracts in the context of UV-induced skin damage. Eligible studies included in vitro, ex vivo, in vivo, and human models assessing outcomes related to oxidative stress, inflammation, molecular signalling pathways, and tumour development. Following screening and eligibility assessment, twelve studies were included in the qualitative synthesis. Results: The included studies suggest that SFN exerts photoprotective effects across multiple experimental models. In murine studies, SFN and SFN-rich extracts were associated with a reduction in tumour incidence, multiplicity, and volume following UV exposure. In human studies, topical SFN application reduced UV-induced erythema and induced cytoprotective enzyme expression, although clinical evidence remains limited. Mechanistically, SFN consistently activated the Nrf2 pathway, leading to increased expression of antioxidant and phase II detoxifying enzymes, and was associated with modulation of inflammatory responses and inhibition of MAPK/AP-1 signalling. Emerging evidence also indicates potential effects on UV-induced metabolic and epigenetic alterations. Conclusions: Current evidence supports a potential role for sulforaphane in mitigating UV-induced skin damage through activation of endogenous defence pathways. However, the available data are predominantly preclinical, and further well-designed clinical studies are needed to clarify its efficacy and translational relevance in humans."

Codonopsis pilosula is the sovereign herb in Shenling Baizhu Formula for ulcerative colitis therapy, and Codonopsis pilosula polysaccharides are its key active components, while their immunomodulatory effects and molecular mechanisms in Shenling Baizhu Formula against ulcerative colitis remain elusive. This study explored the critical role of Codonopsis pilosula polysaccharides and the spermidine-AMPK-mediated mitophagy-cGAS-STING inflammatory axis in regulating intestinal inflammation and ameliorating ulcerative colitis. A dextran sulfate sodium-induced ulcerative colitis mouse model was established to evaluate the indispensable role of Codonopsis pilosula polysaccharides in Shenling Baizhu Formula. Ultra-high performance liquid chromatography metabolomics and 16S ribosomal RNA sequencing were performed to identify key metabolites and gut microbiota. In vitro dextran sulfate sodium-induced ulcerative colitis cellular models (human colorectal adenocarcinoma Caco-2 and human normal colonic epithelial NCM460 cells) were constructed to validate the regulatory mechanism of spermidine on AMPK-mediated mitophagy, inflammatory balance and intestinal epithelial injury. Codonopsis pilosula polysaccharides were essential for the anti-ulcerative colitis efficacy of Shenling Baizhu Formula: removal of Codonopsis pilosula significantly aggravated colonic pathological lesions, intestinal inflammatory responses and oxidative stress in ulcerative colitis mice, whereas Codonopsis pilosula polysaccharides supplementation reversed these abnormal phenotypes (P\u00a0<\u00a00.05). Metabolomics and microbiomics confirmed that Codonopsis pilosula polysaccharides exerted therapeutic effects via spermidine (a key metabolite in glutamate metabolism pathway) and Muribaculaceae. Critically, in vitro dual-cell experiments verified that spermidine activated AMPK-mediated mitophagy to directly inhibit the hyperactivation of cGAS-STING inflammatory axis, thereby restoring intestinal inflammatory homeostasis and alleviating epithelial cell injury in ulcerative colitis. Codonopsis pilosula polysaccharides extracted from the sovereign herb Codonopsis pilosula in Shenling Baizhu Formula ameliorate dextran sulfate sodium-induced ulcerative colitis, and the core mechanism depends on spermidine-triggered AMPK-mediated mitophagy to suppress the cGAS-STING inflammatory signaling axis, which plays a pivotal role in regulating intestinal immunity and repairing mucosal epithelial damage."

Adult SD rats were randomized into Sham operation, PSCI model, TTM, rapamycin (an autophagy inducer), 3-methyladenine (an autophagy inhibitor), and TTM+3-MA groups, and rat models of cognitive impairment were established using a modified thread occlusion method. Cognitive function of the rats was assessed using Morris water maze test. Histopathological changes, neuronal apoptosis, dendritic spines, and protein expressions of FAM134B, LC3, ATG5, P62, GRP78, Bax, Bcl-2, IL-10, IL-1\u03b2, and TNF-\u03b1 were evaluated using HE, Nissl, TUNEL, Golgi staining, immunohistochemistry, immunofluorescence staining, and Western blotting. Compared with the sham-operated rats, the rat models of PSCI showed significantly prolonged escape latency, reduced target quadrant time and platform crossings, severe hippocampal damage, increased ATG5 and GRP78 expression, elevated apoptosis, increased IL-1\u03b2, TNF-\u03b1, Bax, GRP78, and P62 expressions, and decreased IL-10, Bcl-2, and LC3 expressions, with slightly increased FAM134B-LC3 and calnexin-LC3 co-localization. Compared with those in the model group, the rats receiving TTM treatment showed significantly shortened escape latency, increased target quadrant time and platform crossings, increased ATG5 and dendritic spines, decreased GRP78 expression, enhanced FAM134B-LC3 and calnexin-LC3 co-localization, reduced IL-1\u03b2, TNF-\u03b1, Bax, GRP78, and P62 expressions, and increased FAM134B, ATG5, LC3, IL-10, and Bcl-2 expressions; the rats treated with 3-MA showed the opposite changes. Excessive ER stress is activated early after stroke, shifting from adaptive to pro-apoptotic signaling, with insufficient ER-phagy flux. TTM modulates ER-phagy, alleviates ERS, reduces neuroinflammation and apoptosis, protects dendritic spines, and improves cognitive function in rats with PSCI. \u76ee\u7684:

Here, we identify FAM134B/RETREG1 as a specific ER-phagy receptor mediating amyloid precursor protein (APP) degradation. FAM134B directly interacts with ER-localized wild-type and familial mutant APP via their C-terminal domains and recruits LC3 through its LC3-interacting region (LIR) to promote APP delivery to phagophores for lysosomal degradation. In AD, epigenetic silencing at the FAM134B promoter suppresses its transcription by limiting TFEB/TFE3 binding despite their nuclear enrichment. This transcriptional suppression impairs ER-phagy, leading to APP accumulation and exacerbated AD pathology. AAV-mediated hippocampal expression of wild-type, but not LIR-mutant, FAM134B in 5XFAD mice restores ER-phagy, enhances APP clearance, reduces A\u03b2 deposition, preserves synaptic and myelin integrity, and improves cognitive performance. These findings establish FAM134B downregulation as an upstream pathogenic event in AD, suggesting ER-phagy enhancement as a promising strategy to suppress A\u03b2 generation at its source."

Previously, the 1st known ER-phagy receptor gene RETREG1 (RETR1)/FAM134B gene was reported to restrict Ebola virus (EBOV) replication in vivo by inhibiting the viral glycoprotein (GP) and viral protein 40 kDa (VP40) expression, but this mechanism remains unknown. Here, we identify the truncated RETR1/FAM134B isoform 2 (RETR1-2), but not its full-length protein RETR1, as an ER-phagy receptor that targets EBOV-GP for degradation. RETR1-2 broadly triggers GP degradation across ebolavirus species but not Marburg virus and inhibits EBOV replication. Mechanistically, RETR1-2 recognizes EBOV-GP via its luminal domain, undergoes GP-induced oligomerization, and directs GP-containing ER membranes to lysosomes through canonical macro-autophagy. Using unbiased mass spectrometry, we identified TOLLIP as the key cytoplasm adaptor for RETR1-2, which also requires cooperation with the ER chaperone calnexin for EBOV-GP degradation. Notably, the PI3P-binding C2 domain of TOLLIP mediates its interaction with RETR1-2, and the EBOV-GP degradation occurs independently of ubiquitination, revealing an unexpected role for TOLLIP in ER-phagy. Furthermore, EBOV-VP40 antagonizes this pathway by selectively targeting RETR1-2 for macroautophagic degradation independently of TOLLIP, thereby restoring GP expression and viral infectivity. Nevertheless, RETR1-2 reciprocally degrades VP40 via a similar mechanism. Together, these findings define a calnexin-TOLLIP-RETR1-2 axis that links ER quality control to ER-phagy-mediated antiviral restriction and uncover a reciprocal host-virus arms race centered on selective macro-autophagy."

However, the mechanisms by which host proteins utilize ER-phagy to regulate innate immune response during viral infection remains largely unclear. Here, we uncover the regulatory crosstalk between innate immune adapter, ER retention protein Stimulator of Interferon Genes (STING), and the G protein-coupled receptor ADGRE5/CD97 (Cluster of Differentiation 97). Our results demonstrate that CD97 suppresses the STING-mediated type-I interferon (IFN-I) response against DNA virus and cytosolic DNA, thereby promoting herpes simplex virus type 1 (HSV-1) replication in both cells and mice. CD97 facilitates the recruitment of the ER-phagy receptor, FAM134B (family with sequence similarity 134, member B), to initiate ER-phagy, resulting in the degradation of STING subsequent to DNA virus infection. Furthermore, Cd97-deficient mice exhibit higher IFN-I response and greater resistance to HSV-1 infection. Additionally, our findings reveal that inhibiting CD97 with sanguinarine effectively disrupts HSV-1 replication. These findings shed light on the role of CD97 in the innate immune response against DNA virus infections and offer valuable checkpoint for anti-viral STING activation."

Spermidine (SPD) is known to ameliorate age-related cognitive decline, and the gut microbiota is an important source of SPD. Clostridium butyricum (C. butyricum), a probiotic, can alleviate cognitive decline in individuals with various neurodegenerative diseases, and C. butyricum might generate SPD. However, the role of C. butyricum in natural brain aging and the efficacy of C. butyricum and the metabolite SPD in ameliorating age-related cognitive decline remain unclear. Here, we investigated the effects of C. butyricum and its metabolite SPD on cognitive decline during natural brain aging and the mechanisms underlying these effects. Aged rats\u00a0(aged 17 months, n\u202f=\u202f12 per group) were randomly divided into normal saline (NS), C. butyricum (1\u202f\u00d7108\u223c109 CFU/ml, by gavage for two months) and SPD (6.5\u202fmg/kg/d, by gavage for one month) groups. Compared with the NS group, the C. butyricum and SPD groups presented improved spatial reference and recognition memory, reduced aging marker levels by immunohistochemical staining, improved synaptic plasticity-related tissue structure by transmission electron microscopy and Golgi staining, and increased level of synaptophysin and BDNF by immunofluorescence staining and western blotting in the brain. Furthermore, treatment with C. butyricum and SPD enhanced intestinal barrier function and decreased serum proinflammatory factor levels and brain tissue damage due to oxidative stress. There were no significant differences in relevant indicators between the C. butyricum and SPD groups. In conclusion, C. butyricum and its metabolite SPD may delay the cognitive decline caused by normal brain aging by reducing oxidative stress and inflammation."

This review aim of the synthesize mechanistic evidence on \u03b2-sitosterol as a multi-target phytochemical and clarify how its actions connect to gut-brain axis modulation in neurodegeneration. The integrated mechanistic framework linking \u03b2-sitosterol's effects on cholesterol homeostasis, neuroinflammation, mitochondrial function, cholinergic signaling, and microbiota-barrier integrity to cognitive outcomes. Scope: preclinical and early translational evidence on \u03b2-sitosterol alone and with complementary phytochemicals, including nano-delivery strategies. Increasing evidence highlights phytochemicals as promising multi-target therapeutic agents capable of modulating these interconnected pathological processes. \u03b2-Sitosterol exhibits broad activity by regulating cholesterol metabolism, suppressing neuroinflammation, restoring redox balance, preserving mitochondrial function, and inhibiting important Alzheimer's diseases targets, including acetylcholinesterase and butyrylcholinesterase. The mechanisms action of \u03b2-sitosterol may (i) dampen microglial activation via TLR4/NF-\u03baB signaling, (ii) activate Nrf2-dependent antioxidant responses (Nrf2/HO-1), (iii) support mitochondrial function and reduce ROS, (iv) stabilize membrane cholesterol and modulate amyloidogenic processing, and (v) inhibit acetylcholinesterase/butyrylcholinesterase to restore cholinergic tone. Complementary showing a neuroprotective effect actions of other phytochemicals such as curcumin, resveratrol, sulforaphane, and sinapic acid further enhance neuroprotection by modulating pathways like Nrf2/HO-1, TLR4/NF-\u03baB, PI3K/Akt, and autophagy. Collectively, preclinical studies demonstrate that diverse botanical extracts significantly improve cognitive performance, reduce amyloid burden, restore cholinergic function, and attenuate neuroinflammation and oxidative damage. Emerging preclinical evidence suggests in rodent models of amyloid pathology, \u03b2-sitosterol (5-50\u202fmg/kg) has been reported to improve memory in behavioral tests and reduce markers of neuroinflammation and oxidative stress; gut-brain effects include microbiota remodeling and enhanced barrier integrity, which correlate with reduced neuroimmune activation. Advances in nano-delivery systems and functional food formulations substantially improve phytochemical stability, bioavailability, and brain targeting. Available evidence is chiefly preclinical; clinical translation will require standardized dosing, pharmacokinetic and blood-brain barrier penetration studies, and randomized trials with microbiome and cognitive endpoints. Collectively, these findings position phytochemicals as promising candidates for multi-target disease modification and the development of next-generation neurotherapeutic strategies."

This study describes and evaluates a curriculum-integrated learning experience linking experimental pharmacology, cell culture and Nrf2-related gene expression analysis in third-year Biotechnology students. A total of 32 students participated in the survey-based evaluation. The activity used A549 cells, sulforaphane as an Nrf2-activating compound and tert-butyl hydroperoxide as a pro-oxidant stimulus. Students followed an integrated workflow combining treatment design, cell culture handling, Nrf2-related gene selection, PCR-based gene expression analysis and scientific writing. Perceived learning was assessed using paired pre-post Likert-scale items and analyzed with the Wilcoxon matched-pairs signed-rank test. Post-intervention perceptions, satisfaction and open-ended feedback were analyzed descriptively. Students showed significant improvements in all five pre-post items assessing perceived confidence or familiarity (p value < 0.0001). The proportion of students showing improvement ranged from 81.3% to 100%. Post-intervention responses indicated positive perceptions of interdisciplinary integration, technical competencies, digital competencies, data interpretation and research/professional development. Overall satisfaction was high, with a mean score of 8.50 \u00b1 1.10 out of 10; 87.5% of students rated the activity with a score of 8 or higher. Qualitative feedback highlighted interdisciplinary integration and global understanding of the experimental workflow as key strengths. This curriculum-integrated learning experience was associated with perceived gains across pharmacological, cellular and molecular components of a biotechnology workflow. The intervention may provide a transferable model for integrating experiential, research-oriented and competency-based learning in undergraduate biotechnology education."

Aim of this review is to update the knowledge of Nrf2 as neuroprotective agent of PD. Activation of Nrf2, a transcription factor that regulates the expression of antioxidant and cytoprotective genes, has emerged as a promising therapeutic strategy for PD. Nrf2 is a master regulator of the cellular antioxidant response and is responsible for activating the expression of genes that encode antioxidant enzymes such as superoxidedismutase, catalase, and glutathione peroxidase. Pharmacological agents such as sulforaphane, curcumin, and resveratrol have been shown to activate Nrf2 and upregulate the expression of antioxidant genes in preclinical PD models. Clinical trials are currently underway to evaluate the efficacy of these pharmacological agents in patients with PD. While the neuroprotective role of Nrf2 in PD holds great promise for the development of novel therapies, there are several challenges and limitations that need to be addressed in order to harness the full potential of this pathway in the clinic. Overcoming these obstacles will require interdisciplinary collaborations, innovative research approaches, and a greater understanding of the complex pathophysiology of PD. By addressing these challenges, we can move closer to developing effective neuroprotective therapies that can slow or stop the progression of PD and improve the quality of life for patients with this devastating disease."

However, small molecules targeting CLDN14 remain unexplored. Here, we identified mupirocin (MUP), a clinically approved topical antibiotic, as a modulator of CLDN14 protein expression. Quartz crystal microbalance analysis revealed interaction between MUP and recombinant CLDN14 protein with a dissociation constant (Kd) of 2.59\u00a0\u00b1\u00a00.54\u00a0\u03bcM. MUP did not alter CLDN14 mRNA levels but reduced CLDN14 protein stability. Pharmacological inhibition of clathrin-mediated endocytosis and lysosomal degradation significantly reversed the MUP-induced reduction of CLDN14 protein. These results suggest MUP accelerates endocytosis-lysosomal degradation of CLDN14 protein. Other antibiotics failed to decrease CLDN14 expression. Functionally, MUP increased paracellular permeability to mineral ions and enhanced the transepithelial flux of doxorubicin (DXR), an anthracycline anticancer drug, and lucifer yellow, an aqueous small compound. In DLD-1 spheroids, MUP reduced intracellular oxidative stress and nuclear factor erythroid 2-related factor 2 (Nrf2) expression. Consequently, MUP promoted intracellular accumulation of DXR and significantly potentiated its cytotoxic effects in spheroids. Moreover, MUP enhanced the antitumor efficacy of other chemotherapeutic agent oxaliplatin. Sulforaphane, an Nrf2 activator, attenuated the MUP-induced enhancement of anticancer efficacy. These findings suggest that MUP enhances anticancer drug sensitivity in CRC through lysosome-dependent downregulation of CLDN14 protein and suppression of oxidative stress signaling."

Ferroptosis and mitochondrial biogenesis indicators were measured at various time points following MCAO. Various methods, including transmission electron microscopy, immunofluorescence assay, enzyme-linked immunosorbent assay, Western blotting assays, and real-time quantitative reverse transcription polymerase chain reaction (RT-qPCR), were employed to evaluate the impact of NTF on mitochondrial biogenesis and ferroptosis in vivo and in vitro. IS significantly inhibits mitochondrial biogenesis and increases neuronal ferroptosis, with brain damage worsening over time. MCAO groups showed reduced expression of Nrf2, TFAM, ATP, CISD2, FPN, GPX4, SOD, and HO-1, alongside elevated Fe\u00b2\u207a, ROS, and LPO (P < 0.05) compared to the control group.

(P < 0.05). This finding clarifies mitochondrial biogenesis's crucial role, proposes a new \"pathway + molecule\" strategy for IS treatment, and supports NTF's clinical potential, though larger animal models and long-term safety studies are needed. In the context of IS, reduced mitochondrial biogenesis plays an important role in ferroptosis. Targeting the Nrf2/TFAM signaling pathway may improve mitochondrial biogenesis in IS. Furthermore, NTF can mitigate ferroptosis by promoting mitochondrial biogenesis through the Nrf2/TFAM signaling pathway."

Currently, there are no specific medications available for ASD. Increasing attention is now focused on bioactive compounds with anti-inflammatory and antioxidant properties. Sulforaphane (SFN), a key member of the isothiocyanate family, is abundant in cruciferous vegetables. It exhibits potent antioxidant and anti-inflammatory effects with minimal side effects, while oxidative stress and inflammation are recognized triggers in ASD pathogenesis. As research deepens, SFN's physiological activities\u2500including antioxidant, neuroprotective, and anti-inflammatory properties are gaining heightened attention. Building on prior studies, this review comprehensively summarizes seven potential pathways through which SFN protects neurodevelopment or reverses ASD-related neural damage, including Keap1/Nrf2/ARE; MAPKs; NF-\u03baB; HSR; AhR/CYP1; Sirtuin-FOXO; and mTOR/autophagy signaling pathways, elucidating the potential mechanisms underlying its multifaceted actions. This review offers new insights for the comprehensive utilization of sulforaphane and the treatment of ASD."

Here, we examined the effects of two haloacetamides, 2,2-dichloroacetamide (DCAcAm) and 2,2-dibromoacetamide (DBAcAm), on mouse oocyte maturation and identified the underlying mechanisms of toxicity. Both compounds markedly impaired meiotic spindle assembly and compromised the function of multiple organelles, including mitochondria, the endoplasmic reticulum, and the Golgi apparatus, primarily through autophagy dysregulation at specific exposure concentrations, as evidenced by the observation that more than half of the oocytes failed to progress beyond the MII stage. Spermidine supplementation effectively restored autophagic activity and rescued the associated cellular defects, thereby improving both nuclear and cytoplasmic maturation in oocytes. Collectively, these findings demonstrate that spermidine alleviates toxicant-induced deterioration of oocyte quality by regulating autophagy and highlight its potential therapeutic value for reproductive protection and clinical application."

MARCH6 and FAM134B expression levels were measured in glioma tissues. A comparative analysis was conducted on the correlation between clinical parameters and FAM134B expression in 46 glioma patients. FAM134B and MARCH6 were knocked down in glioma cells, followed by detection of cell viability and apoptosis, typical ER stress (ERS) markers (PERK, IRE1\u03b1, eIF2\u03b1, and CHOP), autophagy-related proteins (P62 and LC3B), and autophagosome cytoplasmic accumulation. A mouse glioma model was established for in vivo validation. MARCH6-FAM134B interaction, FAM134B ubiquitination levels, and protein stability were examined. FAM134B expression was high and MARCH6 expression was low in glioma tissues. MARCH6 induced FAM134B protein ubiquitination and degradation, reducing its stability in glioma cells. Knockdown of FAM134B reduced glioma cell survival, inhibited PERK, IRE1\u03b1, eIF2\u03b1, and CHOP expression, decreased LC3I to LC3II conversion, lowered LC3B fluorescence expression, and reduced the accumulation of autophagosomes with continuous ER structures in the cytoplasm, while enhancing apoptosis and P62 expression. This effect can be reversed by knocking down MARCH6. In vivo, FAM134B knockdown suppressed tumorigenesis in mice.

"abstract_text": "ID: 42192129\nTitle: FAM134B-mediated ER-phagy degrades APP and suppresses Alzheimer's disease pathology.\nAbstract: Endoplasmic reticulum autophagy (ER-phagy) is a selective autophagy pathway in which receptor proteins target ER membranes and proteins for degradation, yet its role in Alzheimer's disease (AD) remains unclear. Here, we identify FAM134B/RETREG1 as a specific ER-phagy receptor mediating amyloid precursor protein (APP) degradation. FAM134B directly interacts with ER-localized wild-type and familial mutant APP via their C-terminal domains and recruits LC3 through its LC3-interacting region (LIR) to promote APP delivery to phagophores for lysosomal degradation. In AD, epigenetic silencing at the FAM134B promoter suppresses its transcription by limiting TFEB/TFE3 binding despite their nuclear enrichment. This transcriptional suppression impairs ER-phagy, leading to APP accumulation and exacerbated AD pathology. AAV-mediated hippocampal expression of wild-type, but not LIR-mutant, FAM134B in 5XFAD mice restores ER-phagy, enhances APP clearance, reduces A\u03b2 deposition, preserves synaptic and myelin integrity, and improves cognitive performance. These findings establish FAM134B downregulation as an upstream pathogenic event in AD, suggesting ER-phagy enhancement as a promising strategy to suppress A\u03b2 generation at its source."

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]\n\"Dietary butyrate from resistant starch may synergize with sulforaphane-driven Nrf2 activation and spermidine-mediated FAM134B ER-phagy in order to restore astrocytic EAAT2 membrane trafficking and potentially clear synaptic glutamate excitotoxicity in neurodegeneration.\"\n\nBased on the provided literature, this hypothesis is mechanistically plausible. The evidence indicates that (1) dietary resistant starch increases butyrate production; (2) butyrate, sulforaphane, and spermidine independently activate Nrf2 and antioxidant defenses; (3) FAM134B-mediated ER-phagy is a mechanism for maintaining ER and cellular homeostasis; and (4) restoring astrocytic EAAT2 function is a critical strategy for mitigating glutamate excitotoxicity. While no single study describes this precise tripartite synergy, the individual components and pathways are well-documented as overlapping regulators of neuronal and glial survival in neurodegenerative models.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThis assessment synthesizes evidence regarding the modulation of redox homeostasis (via Nrf2), protein quality control (via ER-phagy), and glutamate uptake (via EAAT2). The proposed synergy between dietary butyrate, sulforaphane, and spermidine offers a novel, multi-target approach to neuroprotection by converging on these shared homeostatic nodes.\n\n### [INTRODUCTION & JUSTIFICATION]\nNeurodegenerative processes such as Alzheimer\u2019s and Parkinson\u2019s diseases are driven by convergent pathologies: oxidative stress, neuroinflammation, and glutamate excitotoxicity. Astrocytic EAAT2, the primary glutamate transporter, is frequently downregulated in these conditions, leading to synaptic glutamate accumulation and subsequent neuronal death. The literature demonstrates that dietary fiber/resistant starch promotes the production of SCFAs like butyrate, which serves as a major energy source for colonocytes and supports gut-brain axis homeostasis. Mechanistically, butyrate regulates Nrf2 and antioxidant pathways. Sulforaphane functions as a potent Nrf2 inducer, while spermidine enhances autophagic flux\u2014specifically FAM134B-mediated ER-phagy. Given that EAAT2 expression and membrane trafficking are susceptible to oxidative and ER stress, the combination of these agents potentially stabilizes the astrocytic proteome and redox environment, thereby preventing the collapse of glutamate buffering.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Butyrate and resistant starch are not merely metabolic fuels but active modulators of the gut-brain axis, impacting both Nrf2 signaling and microbiota composition.\n* FAM134B-mediated ER-phagy is emerging as a critical nexus for both viral restriction and cellular quality control in AD, with its downregulation serving as an early pathogenic event.\n* Spermidine does not only induce autophagy but also impacts hypusination of EIF5A, a process essential for regulating placental and potentially astrocytic protein synthesis.\n* Sulforaphane shows consistent photoprotective and neuroprotective effects, but its clinical utility remains constrained by variability in gut microbiome-mediated conversion.\n* T-2 toxin and cadmium toxicity share a common mechanism of suppressing FAM134B-mediated ER-phagy, linking environmental pollution to homeostatic decline.\n* Spermidine and sulforaphane independently stabilize mitochondrial and ER function, providing a combined metabolic and proteostatic shield for glial cells.\n* The cGAS-STING inflammatory axis is directly repressed by spermidine-mediated mitophagy, highlighting an immunological dimension to its neuroprotective profile.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Growing evidence shows that metabolites generated along the gut-brain axis regulate neuroinflammation. In this study, we demonstrate that oral administration of sodium butyrate (NaB) (300 or 600\u2009mg/kg/day) for 28 days lowered mortality and lessened neuropathological signs in mice infected with SS2 (SC19 strain). Butyrate prophylaxis was associated with lower bacterial loads in the blood and brain tissue, preserved expression of tight junction proteins (ZO-1, Claudin-5, and Occludin) in the brain, and maintained blood-brain barrier (BBB) integrity and permeability. 16S rRNA sequencing analysis revealed that SC19 infection significantly diminished the diversity and richness of the gut microbiota, notably depleting key short-chain fatty acid (SCFA)-producing bacterial taxa. Butyrate intervention restored microbial homeostasis and enriched SCFA-producing communities. Mechanistically, butyrate was associated with upregulated expression of nuclear factor erythroid 2-related factor 2 (Nrf2) and its downstream antioxidant effectors (heme oxygenase 1 [HO-1] and NQO1), while inhibiting phosphorylation of NF-\u03baB p65 and the secretion of proinflammatory cytokines (interleukin-1\u03b2 [IL-1\u03b2], interleukin-6 [IL-6], and tumor necrosis factor-\u03b1 [TNF-\u03b1]) in human cortical microvessels endothelial cells/D3 (hCMEC/D3) cells. Critically, these protective effects were abrogated upon pharmacological inhibition of Nrf2, indicating the critical role of Nrf2 in butyrate-mediated attenuation of neuroinflammation and oxidative stress. Our findings highlight the prophylactic potential of modulating the gut-brain axis as a novel strategy to mitigate central nervous system (CNS) infections associated with foodborne pathogens.\n\nID: 42584118\nTitle: Microbiota-Mediated Conversion of Asiaticoside to Asiatic Acid Restores Intestinal Homeostasis in Mice with Chronic Intestinal Inflammation.\nAbstract: Asiaticoside, a triterpenoid saponin abundant in Centella asiatica, exhibits notable anti-inflammatory activity but suffers from poor oral bioavailability. Here, we reveal a gut microbiota-dependent mechanism underlying its therapeutic efficacy against chronic intestinal inflammation. Using a DSS-induced mouse model and antibiotic-mediated microbiota depletion, we demonstrate that asiaticoside requires microbial metabolism to alleviate epithelial injury, oxidative stress, and inflammatory cytokine production. HPLC analysis showed that asiaticoside is hydrolyzed by gut microbes into asiatic acid, which accumulates in colonic tissues and suppresses IL-17 signaling, NF-\u03baB, and JAK2/STAT3 activation while restoring Nrf2-mediated antioxidant responses. The released glycosides are further fermented into butyrate and other short-chain fatty acids, supporting colonocyte metabolism and intestinal barrier function. Antibiotic treatment abolishes asiaticoside conversion, SCFA production, and therapeutic efficacy. These findings establish microbial biotransformation as a critical determinant of asiaticoside activity and a key mechanism governing natural glycoside pharmacology.\n\nID: 42471327\nTitle: Sheep-derived probiotics alleviate weaning-induced oxidative stress in lambs via the gut-liver axis.\nAbstract: Weaning is a critical transition in lamb production that can disrupt intestinal homeostasis, promote oxidative stress, and contribute to liver injury. This study investigated whether sheep-derived probiotics could mitigate weaning-associated hepatic injury through the gut-liver axis. Microbiota profiling of six intestinal segments from healthy Hu sheep led to the isolation of nine lactic acid bacterial strains. After in vitro screening for antimicrobial and antioxidant activities, Lactiplantibacillus plantarum M1 and Limosilactobacillus reuteri K4 were selected and administered daily to early-weaned lambs from birth to day 30. Probiotic supplementation partially restored relative organ weights, alleviated hepatic histopathological damage, and reduced biochemical markers of liver injury. It also modulated the colonic mucosal microbiota, enhanced intestinal barrier integrity, and increased colonic acetate and butyrate levels. Liver metabolomics revealed enrichment of the pentose phosphate pathway and glutathione metabolism, accompanied by increased hepatic spermidine abundance and activation of the Nrf2-Keap1 antioxidant pathway. Cell-based validation further showed that spermidine attenuated oxidative stress, at least in part, through modulation of Nrf2-Keap1 signaling. Together, these findings suggest that sheep-derived probiotics may alleviate weaning-induced liver injury in lambs through coordinated microbial, metabolic, and antioxidant regulation along the gut-liver axis.\n\nID: 42468209\nTitle: Natural compounds as epigenetic modulators in gynaecological cancers: From chemoresistance to precision oncology.\nAbstract: Gynaecological cancers, including ovarian, cervical, and endometrial malignancies, remain major causes of cancer-related morbidity and mortality because of tumour heterogeneity, recurrence, and therapeutic resistance. Epigenetic dysregulation, involving aberrant DNA methylation, altered histone modifications, dysregulated non-coding RNAs, and N\u2076-methyladenosine (m\u2076A) RNA remodelling, contributes to these processes. Direct evidence that natural compounds modulate m\u2076A machinery in gynaecological cancers remains absent and is considered a knowledge gap. We synthesised evidence on epigenetic alterations in gynaecological cancers and critically evaluated dietary and plant-derived compounds as candidate epigenetic modulators, focusing on preclinical mechanistic studies, pharmacokinetic data, selected early-phase clinical studies, and computational approaches to compound discovery and biomarker stratification. Natural agents, including curcumin, epigallocatechin-3-gallate, sulforaphane, berberine, resveratrol, genistein, diindolylmethane, quercetin, capsaicin, and butyrate, have been reported, mainly in preclinical models, to modulate DNA methyltransferases, histone deacetylases, microRNA networks, tumour suppressor gene expression, and chemosensitivity. However, translation is limited by poor bioavailability, pharmacokinetic variability, insufficient tumour-tissue target-engagement data, weak potency compared with approved epigenetic drugs, limited patient-derived model validation, and a lack of biomarker-driven trials. Compound-specific evidence remains uneven, with stronger support for selected chemosensitising mechanisms than for direct clinical epigenetic efficacy. Natural compounds are mechanistically plausible but clinically under-validated adjunctive epigenetic modulators. Future development requires standardised formulations, improved delivery systems, tumour-tissue pharmacodynamic validation, multi-omics profiling, patient stratification, and biomarker-guided clinical trials to define their realistic role in precision gynaecological oncology. The proposed translational framework may support rational prioritisation of candidates for future preclinical and clinical testing.\n\nID: 42452800\nTitle: Impact of rutin-protein nanoparticles on extruded recombinant rice: structure, digestibility and in vitro fermentation.\nAbstract: Rutin, a flavonol polyphenol, inhibits \u03b1-glucosidase activity and reduces starch digestibility, yet its application is limited by poor aqueous solubility, poor thermal stability, and low bioaccessibility. Rutin-protein nanoparticles have been shown to improve rutin stability. This study aimed to investigate how rutin-protein nanoparticles modulate the digestibility of extruded recombinant rice through multi-scale structural characterization, in vitro digestibility analysis, and in vitro fermentation evaluation. Multi-scale structural analysis revealed that rutin was successfully incorporated into the recombinant rice matrix, interacting with starch chains through hydrogen bonding. This interaction promoted the transformation of starch crystallinity from A-type to A-\u2009+\u2009V-type. Additionally, the short-range order and the content of single and double helices increased. In vitro digestion experiments demonstrated that the bioaccessibility of rutin in the recombinant rice reached 92.49% after co-extrusion with rutin nanoparticles. The resistant starch content was significantly increased, while C\u221e (final digestion extent) and eGI (estimated glycemic index) value were significantly reduced. Moreover, in vitro fermentation results indicated that the recombinant rice with rutin nanoparticles contributed to reducing gas production and increasing the yields of propionate and butyrate. Rutin nanoparticles modulate starch digestibility through a dual mechanism involving the modification of starch structural domains and rutin bioaccessibility. This study provides a novel strategy and technical support for the development of low-glycemic-index functional staple foods. \u00a9 2026 Society of Chemical Industry.\n\nID: 42450386\nTitle: Gastrointestinal Tract Remodeling by Dietary Polysaccharides Mechanistic Insights in Colitis-A Review.\nAbstract: The increased global prevalence of inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn's disease (CD), is a chronic relapsing inflammatory condition of the gastrointestinal tract that creates a substantial socioeconomic burden. Existing pharmacotherapeutic treatments primarily target inflammatory signaling cascades and have disadvantages because of the side effects of drugs, reduced long-term efficacy, and high cost, necessitating the development of safe and sustainable adjunctive therapies. This review synthesizes mechanistic advances regarding dietary polysaccharides as bioactive agents that may have the capacity to induce remodeling of inflamed gastrointestinal tract in colitis and could be an adjunctive strategy as functional food ingredients due to their various biological activities in the management of colitis. Polysaccharides alleviate colitis through several interconnected pathways. First, they correct the gut dysbiosis by enriching beneficial taxa such as Lactobacillus, Bifidobacterium, and Akkermansia muciniphila. Second, fermentation of polysaccharides produces short-chain fatty acids (SCFAs), particularly butyrate, which serve as the primary energy source for colonocytes. Third, they restore intestinal barrier integrity by upregulating tight junction proteins such as ZO-1, occludin, and claudin, also performing pro-inflammatory cascade inhibition and elimination of oxidative stress via Nrf2/HO-1 activation The relationship between structural properties of polysaccharides based on molecular weight, monosaccharide composition, and biological functions of chemically modified dietary polysaccharides in colitis is studied. Dietary polysaccharides are explored here not as replacements for pharmacotherapy but as potential adjunctive or functional food-based interventions that may complement existing treatments as safe, multitargeted, and cost-effective interventions in prevention or long-term management of colitis and IBD. This review presents dietary polysaccharides function not as passive dietary fibers but as bioactive, multi-targeted, structurally dependent agents capable of restoring intestinal homeostasis, suggesting them as potentially safe, adjunctive 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: 42413811\nTitle: Sulforaphane protects cardiomyoblasts against chemical hypoxia by increasing mitochondrial-ER communication and autophagy.\nAbstract: Disruption of the contact sites between mitochondria and the endoplasmic reticulum (MERCSs) adversely affects cardiomyocyte function, necessitating interventions to preserve these connections and maintain the cellular homeostasis. Currently, the nutraceutical sulforaphane (SFN) has emerged as a promising candidate for enhancing MERCSs communication and offering protection in various contexts. In this study, we investigated whether SFN preserves MERCSs functionality in cardiomyoblasts subjected to cobalt chloride (CoCl2)-induced chemical hypoxia. We explored cellular events, including oxidative stress, endoplasmic reticulum stress (ERS), and autophagy, which are regulated by MERCSs. Our findings confirmed that in rat cardiomyoblasts H9c2 pretreated with SFN and exposed to CoCl2, mitochondrial-ER associations were maintained, facilitating the formation of autophagolysosomes. This suggest that autophagy is a mechanism through which SFN protects cardiomyoblasts under chemical hypoxia. This study underscores the significance of MERCSs as functional platforms for maintaining cellular homeostasis and highlights their potential as strategic targets for mitigating the harmful effects of hypoxia in cardiomyoblasts.\n\nID: 42402300\nTitle: Lotus seed resistant starch alleviates OVA-induced food allergy in rats by promoting a Bifidobacterium-enriched gut microbiota and enhancing acetic acid production.\nAbstract: This study established a rat model of ovalbumin (OVA)-induced food allergy. By systematically comparing allergic phenotypes, gut microbiota remodeling, and short-chain fatty acids (SCFAs) profiles among groups receiving single interventions-Type 3 lotus seed resistant starch (LRS3), sodium acetate (AC), Bifidobacterium animalis subsp. lactis DSM 10140 (BA)-and combined interventions (LRS3-AC, LRS3-BA), a multi-level correlation network of \"gut microbiota-SCFAs-immune markers\" was constructed. This study found that single interventions with LRS3, AC, and BA, as well as combined interventions with LRS3-AC and LRS3-BA, all improved allergy-related symptoms and immune dysregulation, with the LRS3-BA group showing the best intervention effect; all intervention groups shifted the gut microbiota structure away from the allergic state. LRS3 promoted the proliferation of Bifidobacterium, and when combined with BA, further promoted Bifidobacterium to become a core indicator bacterium. All intervention groups significantly increased fecal acetic acid concentration, the acetic acid level in the LRS3-BA group reached 2.15\u00a0\u03bcg/mg. As a common downstream effector molecule, acetic acid showed a strong positive correlation with Bifidobacterium and exhibited a stronger association with allergy markers than propionate and butyrate. The study proposed a potential \"LRS3-Bifidobacterium-acetic acid\" axis for regulating the gut microbiota and alleviating food allergies, providing a theoretical basis for developing food allergy intervention strategies targeting the gut microbiota.\n\nID: 42401226\nTitle: Integrated pathways of T-2 toxin-induced neurotoxicity and protection by sodium butyrate in quails.\nAbstract: T-2 toxin, a prevalent mycotoxin in feed, poses severe health risks to poultry. While its systemic toxicity is recognized, its neurotoxic effects in birds, and effective countermeasures, remain underexplored. Sodium butyrate (NaB), a green feed additive, has shown broad biological benefits, but its potential to alleviate T-2-induced neurotoxicity is unclear. This study aimed to investigate the neurotoxic mechanisms of T-2 toxin in quails and evaluate the protective role of sodium butyrate. Two-hundred-and-forty 10-day-old quails were randomly assigned to Control, T-2 toxin (0.9\u00a0mg/kg), NaB (500\u00a0mg/kg), and T-2+NaB groups. After 14 and 28 days, brain tissues were collected for histopathological (hematoxylin-eosin [HE], Nissl, Fluoro-Jade B [FJB] staining) and molecular analyses (RT-qPCR, Western blot, semi-quantitative PCR) to assess oxidative stress, inflammation, and endoplasmic reticulum (ER) stress. T-2 toxin induced severe brain damage, characterized by neuronal vacuolization, loss of Nissl bodies, and degeneration. It concurrently activated oxidative stress (upregulated Nrf2 [nuclear factor erythroid 2-related factor 2], HO-1 [heme oxygenase-1], NQO1 [NAD(P)H: quinone oxidoreductase 1]), neuroinflammation (elevated TNF-\u03b1 [tumor necrosis factor-alpha], IL-1\u03b2 [interleukin-1 beta], IL-6 [interleukin-6], IL-18 [interleukin-18]), and ER stress (increased GRP78 [glucose-regulated protein 78], IRE1\u03b1 [inositol-requiring enzyme 1 alpha], TRAF2 [TNF receptor-associated factor 2], IKK\u03b1/\u03b2 [I\u03baB kinase alpha/beta], XBP1 [X-box binding protein 1]). Sodium butyrate supplementation significantly mitigated these histopathological alterations and downregulated the overactivated molecular pathways across all three axes. This study demonstrates that sodium butyrate confers comprehensive neuroprotection against T-2 toxin in quails by co-ordinately alleviating oxidative stress, neuroinflammation, and ER stress. These findings provide a mechanistic basis for using NaB as a dietary intervention to combat mycotoxin-related neurotoxicity in poultry.\n\nID: 42396672\nTitle: Combining sequence-based approaches with anaerobic microbiology and modelling to understand gut microbial communities.\nAbstract: Gut micro-organisms possess biochemical capabilities that far exceed those of their mammalian hosts, particularly in the ability to gain energy from the breakdown of diet-derived plant material (fibre). This article reviews investigations into gut microbial communities conducted by Harry Flint and his research group. First, extracellular cellulosome and amylosome enzyme complexes were found to mediate the breakdown of plant cell walls and resistant starch by specialised Firmicutes bacteria, both in the human colon and in the rumen. In contrast, Bacteroidetes (Bacteroides, Prevotella spp.) rely on their ability to capture soluble carbohydrates. Human dietary studies examining the impact of fibre sources upon microbiota composition and metabolism identified 'diet-responsive' species. In addition, dominant species of butyrate-producing bacteria, including a subset able to convert lactate to butyrate, were isolated from healthy human volunteers. Most produce butyrate from carbohydrates via butyryl-CoA:acetate CoA-transferase, with uptake of external acetate, while lactate conversion is associated with a highly inducible gene cluster (lct). In pH-controlled chemostat studies, mildly acid pH depressed growth of propionate-producing Bacteroidetes, but favoured butyrate production by Firmicutes. This may explain why % butyrate among SCFA increases with total faecal SCFA concentration in human studies. Although lactate is normally consumed by lactate-utilising bacteria, destabilisation of the microbial community associated with lactate accumulation can result in radically altered microbiota and metabolite profiles. A theoretical model based on microbial functional groups (MFG) was developed to better understand community dynamics. Consequences for nutritional research of our expanding knowledge of the microbial ecology of the human gut are considered.\n\nID: 42379536\nTitle: Ethnopharmacological potential and mechanistic study of Platycodon grandiflorum stems and leaves and Lonicera japonica stems and leaves against acute lung injury.\nAbstract: Platycodon grandiflorum and Lonicera japonica are two plants that have been widely used in traditional ethnic medicine for both medicinal and edible purposes. They are commonly applied in the prevention and treatment of lung-heat-related and inflammatory diseases. However, the stems and leaves of these plants have historically been regarded as by-products, and their therapeutic potential has not been thoroughly explored. Recent studies have shown that the Platycodon grandiflorum stems and leaves, and Lonicera japonica stems and leaves are rich in bioactive compounds, including flavonoids, saponins and phenolic compounds and exhibit notable anti-inflammatory and antioxidant activities. In this study, we investigate the protective mechanism of Platycodon grandiflorum stems and leaves and Lonicera japonica stems and leaves (PLSL) against lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice. This work aims to provide a theoretical basis for resource development and the sustainable, high-value utilization of non-medicinal parts of traditional Chinese medicinal plants. In this study, an LPS-induced inflammatory model using RAW264.7 cells was employed to screen the optimal compatible ratio of PLSL. High-performance liquid chromatography (HPLC) was used to analyze its chemical composition and identify the main active components. In the animal experiment, a mouse model of ALI was established by intranasal instillation of LPS. The severity of lung injury was comprehensively evaluated based on the lung index, lung wet-to-dry (W/D) weight ratio, hematoxylin and eosin staining and Masson's staining. Levels of inflammatory cytokines, including interleukin-6 (IL-6), tumor necrosis factor-\u03b1 (TNF-\u03b1) and interleukin-1\u03b2 (IL-1\u03b2) were measured using ELISA. The transcriptional levels of genes related to the Keap1/Nrf2 pathway were detected by quantitative real-time polymerase chain reaction (qRT-PCR), and the expression and nuclear translocation of Nrf2 and p65 proteins were assessed by immunofluorescence. Meanwhile, 16S rRNA high-throughput sequencing was applied to analyze the cecal microbiota composition in mice, and gas chromatography was used to determine short-chain fatty acid (SCFA) concentrations. Spearman correlation analysis was performed to explore correlations among inflammatory mediators, antioxidant markers and gut microbiota at the genus level. The in vitro results demonstrated that the 4:1 combination of PLSL promoted the migration and proliferation of RAW264.7\u202fcells in a dose-dependent manner and effectively inhibited the overexpression of pro-inflammatory mediators, including cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS), as well as inflammatory cytokines such as TNF-\u03b1, IL-6 and IL-1\u03b2. Meanwhile, PLSL exhibited strong scavenging activity against 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals, 2,2'-azinobis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) cation radicals and hydroxyl radicals (\u00b7OH). HPLC analysis revealed that PLSL contained key active components, including platycodin D, lobetyolin, loganin and chlorogenic acid. In vivo experiments confirmed that PLSL significantly alleviated LPS-induced ALI in mice by regulating the NF-\u03baB and Keap1/Nrf2 signaling pathways, reducing malondialdehyde (MDA) and nitric oxide (NO) levels, increasing glutathione (GSH) levels, suppressing the expression of COX-2, iNOS, TNF-\u03b1, IL-6 and IL-1\u03b2 and modulating the mRNA expression of Keap1, Nrf2, heme oxygenase-1(HO-1) and NAD(P)H quinone oxidoreductase 1 (NQO1). Furthermore, PLSL effectively improved intestinal microbial diversity, increased the relative abundance of beneficial bacteria, including Lachnospiraceae and Alistipes, and significantly elevated cecal short-chain fatty acids (SCFAs), such as acetic acid, propionic acid and butyric acid. This study preliminarily elucidates the multi-target synergistic anti-inflammatory effects of PLSL from the perspectives of inflammatory signaling pathways and gut microbiota. It provides experimental evidence for the whole-plant development and utilization of Platycodon grandiflorum and Lonicera japonica as ethnomedicines.\n\nID: 42352383\nTitle: Alginate Oligosaccharide Alleviates Severe Acute Pancreatitis in Mice via Suppression of Oxidative Stress, Inflammation and Modulation of Intestinal Epithelial Barrier Integrity.\nAbstract: Severe acute pancreatitis (SAP) is a life-threatening inflammatory disorder characterized by high mortality and limited therapeutic options. Alginate oligosaccharide (AOS), a marine-derived bioactive polysaccharide, exhibits prebiotic, anti-inflammatory and antioxidant properties that are effective against various inflammatory diseases. In this study, a mouse model of SAP was established by intraperitoneal injection of cerulein (100 \u03bcg/kg) and lipopolysaccharide (5 mg/kg), and the mice were pretreated with AOS (200 mg/kg) by gavage for 4 consecutive weeks to explore the potential protective efficacy and underlying mechanisms. The results shown that AOS attenuated the severity of SAP, as evidenced by reduced serum amylase and lipase levels, as well as alleviated histopathological injury in both pancreatic and ileal tissues. AOS suppressed the overproduction of pro-inflammatory cytokines (IL-1\u03b2, IL-6, TNF-\u03b1) in serum, pancreas, and ileum at protein or mRNA levels. Moreover, AOS effectively diminished pancreatic and ileal inflammatory infiltration and oxidative stress in SAP mice, accompanied by inhibited the TLR4/MyD88/NF-\u03baB pathway and activated the Nrf2/HO-1 antioxidant axis. Furthermore, AOS restored intestinal barrier integrity, as manifested by upregulated expression of tight junction proteins (claudin-1, occludin, ZO-1), reduced serum diamine oxidase, and decreased bacterial translocation from the gut to the pancreas. It was revealed by 16S rRNA sequencing that AOS ameliorated SAP-induced gut dysbiosis by restoring microbial diversity, normalizing the Firmicutes/Bacteroidetes ratio, enriching beneficial genera (Lactobacillus, Blautia), and enhancing cecal short-chain fatty acid (acetic, propionic, butyric acid) production. Collectively, our findings demonstrate that AOS exerts comprehensive protective effects against SAP through suppression of inflammatory signaling and oxidative stress, as well as restoring gut homeostasis. These results suggest that AOS may serve as a promising prebiotic-based nutritional strategy for the management of SAP.\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-\u03baB 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, \u226512 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: 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 (PPAR\u03b1/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: 42341668\nTitle: Multi-scale structural evolution and fermentation characteristics of four types of lentil resistant starches by human gut microbiota in vitro.\nAbstract: The multi-scale structural evolution and fermentation characteristics of four types of lentil resistant starch (RS2, RS3, RS4, RS5) were examined during vitro human fecal fermentation. Structural analyses indicated a significant reduction in molecular weight for RS2, RS4, and RS5. Crystalline forms were maintained in RS2 (C-type), RS3 (B-type), and RS4 (A-type), whereas RS5 (V-type) underwent a polymorphic transition to an A-type crystalline pattern. Increases in double-helical order and relative crystallinity were observed in RS2 and RS4, indicating preferential microbial degradation of amorphous regions. Scanning electron and confocal laser microscopy revealed extensive structural deterioration, including pitting, surface erosion, and internal fragmentation in RS2, RS4, and RS5, whereas RS3 exhibited only minor surface alterations. Short-chain fatty acid production was highly dependent on specific multi-scale structural features, including crystalline polymorph, molecular weight, and double-helical order. RS2 generated the highest levels of acetate and propionate, whereas RS3 yielded the greatest quantities of butyrate and valerate. Although microbial diversity decreased across all RS groups, distinct taxonomic changes were detected. Specifically, RS2 and RS4 promoted the growth of Ruminococcus, RS3 enriched Roseburia, and RS5 markedly stimulated Bifidobacterium and Megamonas. These findings demonstrate that the specific structure of resistant starch governs its fermentability, SCFA profile, and impact on microbial composition, highlighting the potential for structurally tailored RS to modulate gut health.\n\nID: 42336952\nTitle: Investigation of the effects of sodium butyrate on SH-SY5Y neurons treated with amyloid beta42 and lipopolysaccharide: A computational and experimental study.\nAbstract: Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by amyloid beta42 (A\u03b242) aggregation, neuroinflammation, and synaptic dysfunction. This study combines computational and experimental approaches to investigate the neuroprotective effects of sodium butyrate (NaB). Differentiated SH-SY5Y neurons were exposed to lipopolysaccharide (LPS) and A\u03b2\u2081\u208b\u2084\u2082 to model AD-like conditions, and the potential protective effects of NaB were evaluated. MD simulations indicated that NaB may be associated with destabilization of organized A\u03b2\u2084\u2082 fibrils. Alterations in RMSD, Rg, and SASA values indicated structural instability of A\u03b2\u2084\u2082 fibrils in the presence of NaB. Treatment with NaB (10 and 50 \u00b5M) significantly improved cell viability compared to the LPS\u2009+\u2009A\u03b2 group (p\u2009<\u20090.001) and attenuated apoptosis, as evidenced by reduced expression of Bax, Caspase-3, and FOXO3a (p\u2009<\u20090.0001), alongside upregulation of the anti-apoptotic marker Bcl-2 (p\u2009<\u20090.01). Moreover, NaB markedly increased the expression of neuroprotective and antioxidant genes, including BDNF, Nrf2, SIRT1, and CREB (p\u2009<\u20090.001), thereby restoring pathways involved in neuronal survival, oxidative stress defense, and synaptic plasticity. Collectively, these effects mitigated LPS\u2009+\u2009A\u03b2-induced cytotoxicity, suggesting that NaB exerts its neuroprotective action through epigenetic regulation of stress-response and plasticity networks. Our findings provide robust evidence supporting sodium butyrate as a promising therapeutic candidate for preventing or slowing AD-related neuronal degeneration and highlight its potential translational relevance for future in vivo and clinical investigations.\n\nID: 42326436\nTitle: Dietary Spermidine Mitigates Radiation-Induced Intestinal Injury by Reshaping the Microbiota-Barrier-Inflammation Axis.\nAbstract: Radiation-induced intestinal injury (RIII) is a major complication of radiotherapy, characterized by oxidative stress, intestinal barrier disruption, and gut microbiota dysbiosis. There is an urgent clinical need for highly effective and low-toxicity radioprotective agents. Spermidine (SPD) is a natural polyamine widely found in various foods with well-documented health-promoting properties, yet its role in RIII remains elusive. Using a mouse model of whole-abdominal irradiation, we demonstrated that SPD intervention significantly improved survival rates and mitigated intestinal pathological damage, including crypt loss and villus shortening. Mechanistically, SPD pretreatment activated the Nrf2 signaling pathway, thereby alleviating oxidative stress and reducing DNA double-strand breaks in intestinal epithelial cells. Furthermore, SPD preserved intestinal barrier integrity by enhancing the expression of tight junction proteins (Occludin and ZO-1) and reduced systemic inflammation (serum IL-6). 16S rRNA sequencing revealed that SPD prevented radiation-induced gut dysbiosis by significantly enriching beneficial butyrate-producing bacteria (e.g., Lachnospiraceae_NK4A136_group) while suppressing potential pathogens (e.g., Parabacteroides and Mucispirillum). Our study reveals that SPD exerts multi-targeted protection against RIII by coordinately regulating the \"microbiota-barrier-inflammation\" axis, positioning it as a promising candidate for preventing and treating RIII.\n\nID: 42588134\nTitle: Natural Bioactive Compounds Targeting Key Hallmarks of Aging: Functional Food Potential of Spermidine, Fisetin, Berberine, and Urolithin A.\nAbstract: Naturally derived bioactive compounds that modulate aging-associated mechanisms have attracted growing research interest, yet few reviews examine how such compounds might act together. This narrative review examines four mechanistically distinct compounds, namely spermidine, fisetin, berberine, and urolithin A, as emerging functional food ingredients with scientifically supported effects on key hallmarks of human aging. Spermidine, a dietary polyamine from wheat germ and fermented foods, induces autophagy through EP300 inhibition and is associated with reduced all-cause mortality in prospective studies. Fisetin, a flavonoid from strawberries and apples, exerts senolytic activity by selectively eliminating senescent cells via PI3K/AKT and Bcl-2/Bcl-xL inhibition, with emerging clinical evidence. Berberine, an isoquinoline alkaloid from Berberis species, modulates metabolic dysfunction via AMP-activated protein kinase (AMPK) activation and reshapes gut microbiota composition through direct high intraluminal exposure, with the most extensive clinical dataset of the four compounds. Urolithin A, a gut microbiome-derived postbiotic from ellagitannins in pomegranates and nuts, induces mitophagy via PINK1/Parkin and has been evaluated in a growing number of registered human clinical trials. Together, the four compounds primarily target distinct but complementary aging-associated pathways (autophagy, senolysis, metabolic regulation, mitophagy), suggesting rational potential for combined functional food formulations. Limited direct evidence for their combined use and the need for dedicated co-administration studies are discussed, alongside bioavailability, safety, and regulatory considerations.\n\nID: 42541426\nTitle: Neuroprotective Potential of Spermidine in Drosophila sws Neurodegenerative Model.\nAbstract: Neurodegenerative disorders are characterized by progressive neuronal loss and functional decline, yet effective interventions remain limited. The polyamine spermidine was suggested to exert neuroprotective effects, but its concentration-dependent impact on longevity, neuronal integrity, and behavior remains still not well studied. Here, we investigated the effects of spermidine on lifespan, behavioral responses, brain tissue, target gene expression, and antioxidant status in Drosophila melanogaster model of age-dependent neurodegeneration. Wild-type flies and swiss cheese (sws1) mutants were exposed to 0.5, 1, and 5\u2009mM spermidine from early adulthood. Lifespan analysis revealed that high-dose spermidine (5\u2009mM) reduced survival in both wild-type and sws1 mutants, whereas lower doses (0.5 and 1\u2009mM) significantly improved survival in mutants without affecting wild-type flies. Behavioral assays revealed that sws1 flies exhibited reduced climbing ability compared to controls, which was further decreased at 5\u2009mM. Lower concentrations did not significantly affect locomotor performance. Taste preference for trehalose, impaired in untreated sws1 mutants, was partially restored by spermidine at all tested concentrations. Histological analysis of 10-13-day-old mutants showed a concentration-dependent reduction in degeneration zones within the lamina and medulla at 0.5 and 1\u2009mM, whereas 5\u2009mM had no effect. Biochemical assays indicated mild pro-oxidant effects at 5\u2009mM, reflected by increased malondialdehyde (MDA) levels, while 0.5\u2009mM enhanced antioxidant defenses, including catalase activity and Trolox equivalent antioxidant capacity (TEAC). Our results suggest that spermidine at low doses has the potential to be a general-purpose neuroprotector.\n\nID: 42392052\nTitle: Psychological stress drives aging-like hematopoietic stem cell dysfunction through a brain-gut-bone marrow axis.\nAbstract: Chronic stress influences hematopoietic stem cells (HSCs). However, how psychological stress regulates HSC function remains incompletely understood. Here, we show that psychological stress impairs HSC self-renewal and lymphoid differentiation, inducing aging-like phenotypes. Stress suppresses neuronal activity in the medial prefrontal cortex (mPFC) and periaqueductal gray (PAG), leading to HSC dysfunction, whereas chemogenetic activation of these regions restores HSC function. Psychological stress or chemogenetic inhibition of the mPFC and PAG reduces the abundance of L. reuteri in the gut microbiota and lowers spermidine levels. Mechanistically, spermidine depletion suppresses mitochondrial autophagy, promotes mitochondrial peroxidative stress, and increases ferroptotic stress in HSCs. We further demonstrate that mPFC and PAG activity regulate the intestinal environment through a sympathetic pathway, reducing intestinal mucin levels, L. reuteri abundance, and spermidine levels. These findings identify a brain-gut-bone marrow axis linking psychological stress to aging-like HSC dysfunction through sympathetic regulation of intestinal microbiota and spermidine metabolism.\n\nID: 42308222\nTitle: REPROGRAM: REsilience PROmotion with GeRoprotectors: AssessMent of biological effect: Rationale and protocol for a trial of biological effect.\nAbstract: Ageing is associated with reduced resilience to physiological stressors such as infection and surgery. This reduced resilience is believed to be underpinned by the hallmarks of ageing, the key biological mechanisms driving the aged phenotype. Geroprotectors are drugs that are proposed to slow down the ageing process and promote longevity and healthspan. Despite this, mechanistic studies in healthy older adults are lacking. This trial will test the hypothesis that geroprotectors targeted towards biological mechanisms associated with poor resilience can reverse these pathways within a three-week period. Three geroprotectors with a good safety profile in older adults and evidence of effect on the hallmarks of ageing will be administered to 60 (30 female; 30 male) adults 70\u2009+\u2009. Participants will be randomised to one of three arms (Metformin MR 1500 mg, Fisetin 100 mg or Spermidine 15 mg). Participants will be extensively clinically characterised at baseline. Blood, abdominal adipose tissue and stool samples will be taken at baseline and following the three-week intervention. The primary research question will answer whether a three-week course of Metformin, Spermidine, or Fisetin reduce the number of senescent cells as measured by SA-\u03b2-GAL in adipose biopsies in healthy older volunteers. Additionally, there will be assessment of the effect of the geroprotectors on other hallmarks of ageing, including autophagy, immunosenescence, chronic inflammation, dysregulated mTOR signalling, epigenetic age, DNA damage, dysregulated metabolism, stem cell exhaustion and microbial composition. Ethical approval is in place (24/LO/0549). The main trial report and any sub-studies will be published in high impact peer-reviewed gerontology journals, presented at academic conferences and through a series of public engagement events. Participants enrolled in the study will be informed of the results by a written summary. REPROGRAM was registered with ISRCTN on 10/09/24. ISRCTN47919839.

Here, we investigated whether the polyamine biosynthetic enzyme S-adenosylmethionine decarboxylase 1 (AMD1) regulates tubular senescence and repair outcomes after AKI and elucidated the underlying mechanism. AMD1 dynamics were examined in an ischemia-reperfusion injury model using male C57BL/6J mice by immunofluorescence. AAV-mediated Ksp promoter-driven tubule-specific Amd1 conditional knockdown male mice (Amd1 cKD) were used to assess renal injury, cell-cycle status, senescence, and remodeling, and exogenous spermidine was administered for rescue. DNA damage signaling and p53/p21 activation were evaluated by immunostaining, Western blotting, and EdU incorporation assays. AMD1 was predominantly expressed in the tubular epithelium, with prominent dynamic induction in proximal tubules early after IRI, but declined to baseline levels during the late phase, representing a relative metabolic insufficiency that correlated inversely with fibrosis. Compared with wild-type controls, Amd1 cKD mice exhibited aggravated tubular injury, an over two-fold increase in SA-\u03b2-gal-positive areas, elevated p21, and reduced Ki67+ proliferation. Conversely, spermidine supplementation improved renal function, reduced fibrosis by 75.3%, and decreased senescent regions by 74%. Mechanistically, AMD1 deficiency increased \u03b3H2AX-marked DNA damage and activated the p53/p21 checkpoint, whereas spermidine attenuated this response and restored DNA synthesis capacity. Collectively, tubular AMD1 acts as a metabolic checkpoint that preserves polyamine homeostasis to restrain p53/p21-dependent senescence, promote adaptive repair after AKI, and spermidine supplementation represents a potential strategy to mitigate maladaptive AKI-to-CKD progression.\n\nID: 42264187\nTitle: Nanodelivery strategies for caloric restriction mimetics in age-associated neurodegeneration.\nAbstract: Brain aging is associated mainly with a decline in cognitive function and is a major risk factor for various neurodegenerative disorders (NDDs). Major hallmarks of aging include oxidative stress, chronic neuroinflammation, mitochondrial dysfunction, and impaired proteostasis. Although caloric restriction (CR) has consistently demonstrated neuroprotective effects, its long-term effects in humans remain challenging. Consequently, CRMs such as metformin, spermidine, and curcumin have been widely used because of their ability to recapitulate key molecular effects of CR. Despite their therapeutic effects, the clinical translation of CRMs is significantly limited by their poor bioavailability, rapid metabolism, low aqueous solubility, and inefficient penetration across the blood-brain barrier (BBB). A nanoparticle-based drug delivery system provides a promising approach to address these limitations. Polymeric, liposomal, and lipid-based nanocarriers can be engineered to increase BBB transport via receptor-mediated transcytosis and to enable targeted and sustained drug release. Encapsulation of CRMs within nanoparticles has improved their pharmacokinetic and pharmacodynamic profiles by increasing their stability and bioavailability and reducing systemic degradation. However, targeted delivery of CRMs has been shown to modulate aging-associated pathways, which are necessary for the maintenance of neuronal integrity and synaptic function. This review highlights the potential of CRM-loaded nanocarriers as emerging therapeutic systems to delay brain aging and age-associated disorders. Furthermore, the current challenges and future perspectives on optimizing brain-targeted delivery to enable successful clinical translation in age-related NDDs are discussed.\n\nID: 42225652\nTitle: Insights into the therapeutic strategies for aging and aging-associated diseases.\nAbstract: Aging is a complex biological process characterized by progressive functional decline, driving the incidence of age-related diseases such as neurodegeneration, metabolic disorders, and cardiovascular diseases. Therapeutic strategies targeting aging hallmarks can delay aging and mitigate disease risk. Emerging interventions focus on modulating core aging mechanisms, including cellular senescence, metabolic dysfunction, epigenetic alterations, and mitochondrial impairment, etc. Recent advances have focused on three strategies: senolytics (eliminating senescent cells, e.g., dasatinib + quercetin), senomorphics (inhibiting the senescence-associated secretory phenotype, e.g., rapamycin), and senoreversion (rejuvenating senescent cells via epigenetic reprogramming). Additionally, metabolic interventions such as caloric restriction mimetics (e.g., spermidine, \u03b1-ketoglutarate, ergothioneine) enhance mitochondrial function, activate autophagy, and reprogram energy metabolism, demonstrating lifespan extension and healthspan improvement in preclinical models. Collectively, these approaches hold promise for delaying aging and alleviating age-related pathologies, facilitating the transition to precision longevity medicine. Concurrently, artificial intelligence (AI) accelerates discovery by integrating multiomics data, predicting candidate compounds, identifying biomarkers, and enabling personalized interventions. Despite advancements, challenges remain in target specificity, off-target effects, and clinical translation. The convergence of AI, multitarget strategies, and precision medicine signals a transformative era in extending healthspan and combating aging-associated diseases. This review systematically summarizes current breakthroughs, clinical landscapes, and future directions in aging therapeutics, underscoring interdisciplinary strategies to redefine healthy aging.\n\nID: 42212335\nTitle: VDR-Spermidine Axis Protects Against Age-Related Granulosa Cell Dysfunction and Follicular Decline via DNMTs-Mediated p53 Methylation.\nAbstract: Ovarian aging, marked by a decline in follicle quantity and quality, is a complex process whose underlying mechanisms remain elusive. Here, we identify the vitamin D receptor (Vdr) as a key anti-aging transcription factor whose expression in granulosa cells (GCs) declines with age. Using GCs-specific Vdr knockout (cVKO) mice and a Vdr-knockout (VKO) human granulosa-like cell line, we demonstrate that loss of Vdr triggers GCs aging and disrupts ovarian function. Integrated transcriptomic and metabolomic analyses from VKO and WT cells revealed that Vdr loss downregulates the de novo spermidine (SPD) biosynthesis by directly suppressing the transcription of ornithine decarboxylase (ODC1). This led to SPD depletion, which in turn inhibited DNA methyltransferase (DNMTs) activity, resulting in hypomethylation of the p53 promoter and activation of the p53/p21 pathway. Crucially, supplementation with either SPD or its upstream methyl donor S-adenosylmethionine (SAM) rescued cVKO and VKO cell aging, improved hormonal profiles and promoted follicular development in cVKO mice. Furthermore, both supplements effectively delayed ovarian aging and improved fertility in naturally aged mice. Our study unveils the Vdr-spermidine-DNMTs axis as a fundamental mechanism safeguarding against ovarian aging, highlighting SPD and SAM as promising therapeutic agents for age-related female infertility.\n\nID: 42210432\nTitle: Reproductive aging drives deterministic microbiota assembly to mitigate uterine oxidative phosphorylation impairment via spermidine production in laying hens.\nAbstract: Reproductive aging represents a critical physiological bottleneck characterized by a progressive decline in tissue homeostasis and physiological function. While the gut microbiota is known to shift during host aging, the ecological forces governing the assembly of the reproductive microbiota and its functional feedback on uterine homeostasis remain poorly understood. We demonstrated that uterine aging drives a transition from stochastic to deterministic microbial community assembly, selecting for a microbiota enriched in Rhodococcus in aged laying hens. Multi-omics analyses revealed that this deterministic shift acts as a compensatory mechanism to counteract age-related energy metabolism decline in the uterus. Mechanistically, the aged uterus suffered from oxidative phosphorylation impairment due to PARP1-mediated NAD+\u2009depletion in response to accumulated DNA damage. However, the specific colonization of Rhodococcus ruber, or the administration of its metabolite spermidine, rescued this phenotype. Spermidine improved uterine energy metabolism by inducing PINK1/Parkin-mediated mitophagy, thereby restoring mitochondrial quality control and ATP production essential for eggshell biomineralization. This study uncovers a previously unrecognized role of the microbiota in reproductive aging: resident microbes enhance oxidative phosphorylation in the aged uterus through the metabolite spermidine, which induces mitophagy. This process alleviates cellular energy deficiency caused by PARP1-mediated NAD\u2009+\u2009depletion, elucidating a key mechanism of host-microbe interaction in maintaining uterine energy homeostasis during aging. Video Abstract.\n\nID: 42197044\nTitle: Dietary Polyamine Intake Across Age Groups in Spain: A Comprehensive Assessment.\nAbstract: Polyamines, including putrescine (PU), spermidine (SPD), and spermine (SPM), are ubiquitous bioactive compounds essential for cell proliferation, genomic stability, autophagy, and the regulation of oxidative and inflammatory responses. Growing evidence, particularly for SPD, suggests that polyamine-rich diets may protect against age-related conditions such as cardiovascular disease, metabolic syndrome, and neurodegenerative disorders. As endogenous polyamine synthesis declines with age, dietary intake becomes increasingly important, especially in older adults. This study estimated each polyamine (PU, SPD and SPM) and total polyamine intake in the Spanish population using food consumption data from the Spanish Ministry of Agriculture, Fisheries and Food. Intakes were evaluated across four age groups, and major dietary sources were identified. Total polyamine intake increased with age, reaching 393 \u00b5mol/day in adults over 65 years. PU accounted for 49% of total intake, followed by SPD (29%) and SPM (22%). Plant-based foods were the primary contributors to SPD intake, particularly vegetables (36%), fruits (26%), and cereals (18%). PU intake was also predominantly plant-derived, mainly from fruits (58%) and vegetables (23%), whereas SPM intake was largely associated with meat products (59%). A theoretical Mediterranean diet model yielded a slightly higher total polyamine intake of 406.6 \u00b5mol/day and a substantially greater SPD intake than that observed in older adults (193.99 \u00b5mol/day versus 121.62 \u00b5mol/day). Overall, estimated polyamine intake in the Spanish population fell below the optimal level of 540 \u00b5mol/day proposed in the literature. These findings highlight the need for public health strategies promoting consumption of polyamine-rich foods, particularly vegetables, legumes, whole grains, and fruits, to support healthy aging and reduce the risk of age-related diseases.\n\nID: 42169618\nTitle: Spermidine Mitigates Immune Cell Senescence and Boosts Vaccine Responses in Healthy Older Adults-A Pilot Study.\nAbstract: Older adults are highly vulnerable to infectious diseases, and vaccines are often less effective in this population because of diminished B and T cell memory responses driven by impaired autophagy, immunosenescence, and chronic low-grade inflammation. Spermidine has been shown to counteract immunosenescence and induce autophagy in preclinical models, and its levels decline with age in humans. We conducted a double-blind, randomised, placebo-controlled pilot study in 40 adults over 65\u2009years of age following their third SARS-CoV-2 vaccine dose to assess the safety of Spermidine and its effects on vaccine-induced immunity. Daily oral supplementation (6\u2009mg, 13\u2009weeks) was well-tolerated. Vaccine non-responsiveness was common, and non-responders exhibited a distinct immune-senescence signature marked by elevated p16, mTOR signalling, and \u03b3-H2AX+ DNA damage in lymphocytes. Spermidine reversed these features and significantly enhanced spike-specific IgG secretion, memory B cell recall responses and neutralising antibody activity, specifically in non-responders. Single-cell RNA-seq after treatment revealed increased expression of TFEB targets and autophagy-related genes in B cells, in line with elevated autophagic flux. These findings suggest that targeting immune cell senescence with Spermidine may improve vaccine responsiveness in older adults and highlight immune-senescence markers as potential predictors of vaccine failure in ageing populations.\n\nID: 42092427\nTitle: Clostridium butyricum and its metabolite spermidine delay cognitive decline during natural brain aging by reducing inflammation and oxidative stress.\nAbstract: Brain aging primarily manifests as cognitive decline. Spermidine (SPD) is known to ameliorate age-related cognitive decline, and the gut microbiota is an important source of SPD. Clostridium butyricum (C. butyricum), a probiotic, can alleviate cognitive decline in individuals with various neurodegenerative diseases, and C. butyricum might generate SPD. However, the role of C. butyricum in natural brain aging and the efficacy of C. butyricum and the metabolite SPD in ameliorating age-related cognitive decline remain unclear. Here, we investigated the effects of C. butyricum and its metabolite SPD on cognitive decline during natural brain aging and the mechanisms underlying these effects. Aged rats\u00a0(aged 17 months, n\u202f=\u202f12 per group) were randomly divided into normal saline (NS), C. butyricum (1\u202f\u00d7108\u223c109 CFU/ml, by gavage for two months) and SPD (6.5\u202fmg/kg/d, by gavage for one month) groups. Compared with the NS group, the C. butyricum and SPD groups presented improved spatial reference and recognition memory, reduced aging marker levels by immunohistochemical staining, improved synaptic plasticity-related tissue structure by transmission electron microscopy and Golgi staining, and increased level of synaptophysin and BDNF by immunofluorescence staining and western blotting in the brain. Furthermore, treatment with C. butyricum and SPD enhanced intestinal barrier function and decreased serum proinflammatory factor levels and brain tissue damage due to oxidative stress. There were no significant differences in relevant indicators between the C. butyricum and SPD groups. In conclusion, C. butyricum and its metabolite SPD may delay the cognitive decline caused by normal brain aging by reducing oxidative stress and inflammation.\n\nID: 42086115\nTitle: Polyamines and autophagy as a dynamic regulatory network in skeletal muscle regeneration and aging.\nAbstract: Autophagy is a core cellular mechanism that preserves tissue homeostasis by removing damaged proteins and organelles. In skeletal muscle, proper regulation of autophagic flux is essential for maintaining metabolic and structural integrity, whereas its disruption contributes to muscle atrophy, metabolic dysfunction, and age-related functional decline. Increasing evidence identifies polyamines, particularly spermidine (Spd), as important modulators of autophagy and cellular resilience, with beneficial effects on stress responses, metabolic regulation, and lifespan extension. Physical exercise likewise acts as a physiological inducer of autophagy, promoting muscle remodelling, mitochondrial quality control, and adaptive responses to stress. Within this framework, spermine oxidase (SMOX) has emerged as a relevant regulator of muscle homeostasis. SMOX expression is maintained in healthy muscle but declines in atrophic conditions. By converting spermine into spermidine, SMOX may help sustain autophagy-related pathways and support muscle mass under physiological conditions. This review explores the interplay between exercise, spermidine, and SMOX, highlighting autophagy as a unifying regulatory axis. We summarize current evidence on their individual and combined roles in preserving muscle function and discuss their potential relevance for promoting healthy muscle aging and counteracting sarcopenia.\n\nID: 42012729\nTitle: Spermidine in the aging brain: mechanisms, preclinical evidence, and clinical perspectives.\nAbstract: Spermidine, a naturally occurring polyamine, has emerged as a candidate modulator of brain aging because it regulates autophagy, mitochondrial function, oxidative balance, and neuroinflammatory signaling. This review summarizes current knowledge on spermidine biology, including its synthesis, catabolism, transport, and cell-specific handling in neurons and glia, with emphasis on ATP13A2/ATP13A4-dependent trafficking and EP300-linked autophagy. Preclinical studies consistently show that spermidine enhances proteostasis, reduces soluble amyloid-beta, improves microglial phagocytic activity, preserves mitochondrial fitness, and attenuates inflammatory responses in models of aging and neurodegeneration. Human evidence is encouraging but still limited: observational studies associate higher dietary spermidine intake with better cognitive outcomes, whereas interventional trials suggest possible benefits in subjective cognitive decline and mild dementia, with variable dose-dependent effects. Overall, spermidine is a biologically plausible nutraceutical for healthy brain aging, but larger, well-designed clinical trials are needed to define efficacy, bioavailability, safety, and optimal therapeutic use across prodromal, early-stage, and disease-specific patient populations.\n\nID: 42002642\nTitle: Spermidine preserves cardiac systolic function in estrogen-deprived rats with accelerated aging via metabolic and mitochondrial reprogramming.\nAbstract: Aging and estrogen deprivation, particularly in postmenopausal women, significantly increase the risk of cardiovascular diseases by driving metabolic and mitochondrial dysfunctions. Although estrogen replacement therapy is cardioprotective, its long-term risks are significant. Spermidine, a natural polyamine, is known for its longevity and cardioprotective effects, but its efficacy in models combining accelerated aging-like model and estrogen deprivation is unclear. Seventy female Wistar rats were separated into sham and ovariectomy (OVX) groups. After twelve weeks, sham-operated rats were divided into three groups and treated with distilled water (Sham-V; p.o.), D-galactose (Sham-D; 150\u00a0mg/kg/day; s.c.), and spermidine (Sham-DS; 20\u00a0mg/kg/day; p.o.) for eight weeks. After ovariectomy, the OVX-operated rats were given D-galactose for 12 weeks to accelerated aging-like model, and were subdivided into four groups and treated with distilled water (OVX-D; p.o.), spermidine (OVX-DS; 20\u00a0mg/kg/day; p.o.), sesame oil (OVX-DO; estrogen vehicle; s.c.), and estrogen (OVX-DE; estradiol; 50\u00a0\u00b5g/kg/day; s.c.) for eight weeks. Rats in both accelerated aging-like model and estrogen deprivation groups developed cardiometabolic dysfunction indicated by dyslipidemia, insulin resistance, mitochondrial dysfunction, impaired mitophagy, and apoptosis. Spermidine significantly improved these adverse effects, comparable to estrogen, without altering cardiac senescence and insulin resistance. Spermidine could serve as a potential therapeutic strategy for mitigating cardiometabolic complications in postmenopausal populations.\n\nID: 41754095\nTitle: The Diet-Microbiota-Polyamine Axis in Intestinal Aging: Microbial Pathways, Functional Foods, and Physiological Implications.\nAbstract: Intestinal aging is characterized by a gradual decline in epithelial renewal capacity, barrier function, immune balance, and metabolic regulation, often accompanied by shifts in gut microbial composition. Polyamines, including putrescine, spermidine, and spermine, are vital microbial-host metabolites that support intestinal cell growth, autophagy, immune modulation, and mucosal repair. With advancing age, both host-derived and microbiota-mediated polyamine production declines, contributing to intestinal dysfunction and heightened vulnerability to inflammation and age-related disorders. This review explores the diet-microbiota-polyamine axis as a key biological framework influencing intestinal aging. It aims to integrate evidence on how dietary components and functional foods shape gut microbial ecology and, in turn, regulate microbial polyamine biosynthetic pathways that impact intestinal health. The review highlights major microbial contributors to polyamine metabolism, particularly lactic acid bacteria, and outlines mechanistic pathways linking polyamines to epithelial regeneration, inflammatory control, and gut barrier maintenance. It further discusses how age-associated dysbiosis disrupts these interactions and evaluates nutritional and microbial-based strategies such as fermented foods, prebiotics, and probiotics that may enhance polyamine availability and restore gut homeostasis. From the standpoint of food microbiology and human physiology, this synthesis underscores the translational potential of targeting microbial polyamine production through diet-based interventions. This article presents a narrative review synthesizing experimental, animal, and emerging human evidence on microbial and dietary polyamines in intestinal aging. In conclusion, modulating the diet-microbiota-polyamine axis represents a promising strategy to promote healthy intestinal aging, meriting deeper mechanistic exploration and validation through clinical studies.\n\nID: 41617890\nTitle: Polyamine metabolism as a regulator of cellular and organismal aging.\nAbstract: Polyamines - putrescine, spermidine, and spermine - are ubiquitous cationic molecules that are essential for cellular proliferation and homeostasis. Their intracellular concentrations decline with age, contributing to physiological and cognitive deterioration. Recent studies have revealed that spermidine supplementation extends lifespan and improves cognitive and cardiac function in various model organisms, suggesting that maintaining polyamine balance has anti-aging potential. Polyamine metabolism is tightly regulated through biosynthesis, degradation, and transport; however, age-associated upregulation of spermine oxidase (SMOX) and accumulation of its toxic byproduct acrolein promote oxidative damage and cellular senescence. Suppressing SMOX activity or polyamine degradation attenuates senescence markers and DNA damage, highlighting spermine catabolism as a therapeutic target. Polyamines also modulate epigenetic regulation, including DNA methylation and histone acetylation, thereby influencing gene expression and chromatin structure during aging. Moreover, polyamine-dependent hypusination of eIF5A sustains protein synthesis in senescent cells. These multifaceted actions indicate that polyamine metabolism integrates redox control, translational regulation, epigenetic maintenance and autophagy to determine cellular and organismal longevity. While animal studies demonstrate clear anti-aging effects of spermidine and spermine, human clinical evidence remains limited, with variable outcomes likely due to bioavailability and metabolic conversion. Future strategies combining dietary or probiotic polyamine enhancement, enzyme-targeted inhibitors, and personalized metabolic interventions hold promise for extending healthspan. Collectively, maintaining optimal polyamine homeostasis emerges as a key approach to counteract aging and age-related diseases.\n\nID: 41612464\nTitle: SS-31 improves the quality of maternally aged oocytes by ameliorating mitochondrial function and metabolism.\nAbstract: Reproductive aging is closely associated with poor oocyte quality in vitro maturation, but effective approaches to ameliorate it have still not been fully determined. Here, we found that SS-31 supplementation efficaciously improved oocyte maturation and early embryonic development from aged mice. Specifically, SS-31 remarkably restored the normal spindle/chromosome structure, fertilization ability, mitochondrial distribution, \u0394\u03a8m and mitophagy in aged oocytes. In contrast, SS-31 reduced oocyte aneuploidy, ROS accumulation and DNA damage. Mechanistically, single-cell transcriptome analysis reveals that SS-31 increased the maternal mRNA degradation, and the levels of genes associated with mitochondrial function and mitophagy in aged oocytes, such as Pink1, Rps27a, Tomm7 and Map1lc3b. In addition, SS-31 suppressed chromatin organization, histone modification and chromatin remodeling pathways. Moreover, we applied the single-cell untargeted metabolomics to identify that SS-31 increased the levels of spermidine and GSH, which were critical metabolites to protect oocytes against aging. Our data reveal that the beneficial effect of SS-31 on oocyte quality from advanced age is mainly mediated by restoration of mitochondrial function, mitophagy and anti-aging metabolites. It provides a potential strategy for improving oocyte quality to extend the reproductive lifespan of female animals.\n\nID: 42618638\nTitle: Sulforaphane mitigates behavioral deficits in experimental chronic kidney disease through regulation of Nrf2/NLRP3 inflammasome.\nAbstract: Depression is one of the most prevalent psychiatric disorders among patients with chronic kidney disease (CKD). Growing evidence suggests that oxidative stress and inflammation contribute to the development of CKD-associated depression. Sulforaphane, a natural isothiocyanate with potent antioxidant and anti-inflammatory properties, has demonstrated promising neuroprotective and antidepressant-like effects. Therefore, this study investigated the effects of sulforaphane on depressive-like behavior in an adenine-induced CKD rat model and explored the underlying mechanisms, using fluoxetine as a reference treatment. Forty adult male Wistar rats were randomly assigned to five equal groups. Group I (control) received the drug vehicle, Group II received an adenine-containing diet (0.25% w/w in feed), Group III received an adenine-containing diet plus oral sulforaphane (5\u00a0mg/kg/day), Group IV received an adenine-containing diet plus oral sulforaphane (0.5\u00a0mg/kg/day), and Group V received an adenine-containing diet plus oral fluoxetine (10\u00a0mg/kg/day). The experimental period lasted for 5\u00a0weeks. Behavioral assessments were conducted during the final week using the sucrose preference, light-dark, and forced swim tests. Following euthanasia, kidney and brain tissues were collected for biochemical and histopathological analyses. Brain oxidative stress markers, including malondialdehyde (MDA), reduced glutathione (GSH), and nuclear factor erythroid 2-related factor 2 (Nrf2), as well as inflammatory markers, including interleukin-1\u03b2 (IL-1\u03b2), tumor necrosis factor-\u03b1 (TNF-\u03b1), and NOD-like receptor protein 3 (NLRP3) inflammasome, were evaluated. Sulforaphane dose-dependently improved renal function, histopathological alterations, behavioral performance, and brain antioxidant and anti-inflammatory status. These beneficial effects may be associated, at least in part, with modulation of the Nrf2/NLRP3 signaling pathway.\n\nID: 42617706\nTitle: Exercise and phytochemicals as modulators of redox homeostasis in aging.\nAbstract: Reduced resilience to physiological stress, including impaired redox signaling, is a hallmark of aging that contributes to chronic disease risk. The transcription factor Nrf2 is widely considered a master regulator of redox homeostasis. Although exercise is a potent activator of Nrf2 signaling, exercise-induced Nrf2 activation is attenuated with aging. One emerging strategy to restore or potentiate exercise-induced Nrf2 activation in older adults is to combine exercise with phytochemicals known to modulate Nrf2 activity. This review summarizes redox homeostasis and Nrf2 signaling during exercise and training, how these processes are impacted during aging, and the current evidence for and against combining phytochemicals known to activate Nrf2 signaling (i.e., astaxanthin, curcumin, and sulforaphane) with exercise in older populations. We also highlight mechanistic differences between exercise- and phytochemical-induced Nrf2 activation and consider whether combining these two interventions could enhance redox resilience more than either alone. Despite early signs of promise (largely derived from cell culture and rodent studies), current evidence is insufficient to fully support the benefits of combining phytochemicals with exercise, with limited clinical data in aging populations. Nevertheless, the rationale for further research is compelling, and we outline key translational challenges and priorities for future trials to advance the field forward.\n\nID: 42600300\nTitle: Investigation of the Nrf2-Keap1 signaling pathway's response to oxidative stress in Meretrix meretrix.\nAbstract: The Keap1-Nrf2 signaling pathway primarily regulates cytoprotective responses to oxidative and electrophilic stress. This pathway involves two key proteins: Nuclear factor erythroid 2-related factor 2 (Nrf2), a crucial regulator of cellular defenses, and Kelch ECH associating protein 1 (Keap1), a repressor protein. Keap1 interacted with Nrf2, leading to the degradation of Nrf2 via the ubiquitin-proteasome pathway. In this study, we cloned these proteins from Meretrix meretrix, obtaining full-length cDNA sequences of 2172\u202fbp and 1791\u202fbp. Sequence alignment and phylogenetic analysis revealed that Nrf2 and Keap1 were highly conserved among Molluscan species, yet distinct in M. meretrix. MmNrf2 and MmKeap1 were expressed in multiple tissues, with the highest expression levels in the digestive gland and gill, respectively. We conducted RNA interference experiments to analyze the mRNA transcription profiles of key genes in the Keap1-Nrf2 signaling pathway (Nrf2, Keap1, Maf, p62), xenobiotic metabolism genes (CYP3A3 and Pgp), and antioxidant and detoxification genes (SOD, NQO1, CAT, and GCLM). We also measured ROS, T-AOC, malondialdehyde (MDA), and GSH levels in the digestive gland after exposure to 10\u202f\u03bcg/L benzo[a]pyrene (BaP) for 6\u202fh. Results showed a 60.95% decrease in MmNrf2 mRNA levels. Changes in the Keap1-Nrf2 signaling pathway and BaP-induced oxidative stress gene expression aligned with MmNrf2, suggesting its important role in activating antioxidant and detoxification genes. Additionally, ROS, T-AOC, and GSH levels in the digestive gland significantly increased after 10\u202f\u03bcg/L BaP exposure but decreased 6\u202fh post-siNrf2 injection. We also evaluated the effects of 10\u202f\u03bcM Sulforaphane on the Keap1-Nrf2 signaling pathway and BaP-induced oxidative stress indicators in M. meretrix using real-time PCR after 24\u202fh of exposure to 1\u202f\u03bcg/L BaP. The combined exposure to 10\u202f\u03bcM SFN and 1\u202f\u03bcg/L BaP led to decreased ROS levels compared with BaP single treatment, while T-AOC and GSH levels increased significantly; all genes showed induced expression after 24\u202fh, though slightly decreased after adding 10\u202f\u03bcM SFN. In conclusion, our data imply that MmNrf2 responds to oxidative stress factors, regulated the Keap1-Nrf2 signaling pathway, and played a crucial role in modulating antioxidant enzyme gene expression in bivalve mollusks.\n\nID: 42546806\nTitle: The utility of FRET/FLIM-based bioassays for monitoring Nrf2 activation in single live cells.\nAbstract: The Kelch-like ECH-associated protein 1 - Nuclear factor erythroid 2-related factor 2 (Keap1-Nrf2) partnership is vital for protection against oxidative stress, and its dysregulation has been linked to the pathogenesis of numerous chronic diseases. Under homeostatic conditions, Keap1 targets Nrf2 for ubiquitination and proteasomal degradation. When Keap1 is inactivated by electrophiles or Keap1-Nrf2 protein-protein interaction (PPI) inhibitors (termed inducers), Nrf2 accumulates and, in association with a small musculoaponeurotic fibrosarcoma (sMaf) protein, induces the transcription of networks of genes encoding cytoprotective proteins. To understand the PPIs between Nrf2 and Keap1 and the effect of inducers in the cellular context, we expressed GFP-Nrf2 and Keap1-mCherry fusion proteins and employed F\u00f6rster resonance energy transfer (FRET)-based multiphoton fluorescence lifetime imaging microscopy (FLIM). PPI inhibitors, but not electrophiles, caused dissociation of GFP-Nrf2 from Keap1-mCherry. To monitor the protein stability of Nrf2, we developed a genetically encoded FLIM-timer-tagged Nrf2, which combines sfGFP and mCherry connected by a linker positioning the fluorophores in a way that promotes FRET. In cells co-expressing stoichiometric amounts of FLIM-timer-Nrf2 with Keap1 from a single promoter, the addition of sulforaphane, the classical Keap1-targeting electrophile, decreased the fluorescence lifetime of the Nrf2-FLIM-timer, consistent with Nrf2 stabilization. Such decrease was also observed upon depletion of either the N-terminal Keap1-binding motif of Nrf2, or a degron within its Neh6 domain that confers \u03b2-TrCP-dependent degradation. These findings show the utility of FRET/FLIM-based bioassays for monitoring Nrf2 activation and illustrate their potential for exploring various aspects of the oxidative stress response.\n\nID: 42530545\nTitle: Genetic and pharmacologic modulations elucidate NRF2 protective role in acute pancreatitis.\nAbstract: Acute pancreatitis (AP) is a potentially fatal disease of the exocrine pancreas. The disease pathogenesis remains obscure, and no effective treatment is available. Uncontrolled, deregulated inflammation is a major cause of systemic complications in AP; however, approaches to reduce inflammation in human disease by inhibiting inflammatory mediators encountered multiple challenges and have not been successful. Oxidative stress drives inflammation in many diseases but its role in AP remains poorly understood. This study evaluates the role of NRF2, the master antioxidant defense transcription factor, in the inflammatory response and severity of experimental AP in mouse and cellular (ex vivo) models. Pancreas-specific genetic ablation of NRF2 worsened nonalcoholic and alcohol-mediated AP by downregulating antioxidant gene expression and upregulating inflammatory mediators, as shown by RNA-seq analysis. Pancreatic NRF2 was activated in the experimental AP models; however, this activation was insufficient to prevent oxidative stress and inflammation. Additional pharmacologic NRF2 activation with sulforaphane markedly reduced oxidative stress, inflammation, and other pancreatitis responses; importantly, it ameliorated a recurrent episode of AP. The results highlight a major role of NRF2 in protecting against oxidative stress and inflammation in AP; and suggest pharmacologic activation of NRF2 as a promising therapeutic strategy to mitigate inflammation and reduce the severity of pancreatitis.\n\nID: 42525741\nTitle: Astrocyte redox imbalance underlies prelimbic neuronal hypoactivity and maladaptive affective behaviors in epilepsy.\nAbstract: A fundamental but unanswered question in neuropsychiatry is whether the psychiatric symptoms of epilepsy are caused by the same or a separate pathophysiology as seizures. To address this question, we investigated a monogenic form of epilepsy (pyridoxine-dependent epilepsy) caused by aldehyde dehydrogenase 7 family member A1 (ALDH7A1) mutations. ALDH7A1 global knockout mice exhibited both seizure-associated and maladaptive affective behavioral phenotypes. However, seizure phenotypes were caused by ALDH7A1 deletion in hepatocytes whereas maladaptive affective behaviors were caused by ALDH7A1 deletion in astrocytes. Deletion in astrocytes disrupted astrocyte redox homeostasis, impairing regulation of extracellular ion concentrations and reducing neuronal activity in the prelimbic cortex. Sulforaphane, which activates the NRF2 antioxidant pathway, restored prelimbic neuronal activity and rescued maladaptive affective behaviors in ALDH7A1 knockout mice but did not prevent seizures. These studies implicate astrocyte redox homeostasis and prelimbic hypoactivity in maladaptive affective behavioral phenotypes in a congenital form of epilepsy, which are mechanistically and therapeutically dissociable from seizure pathophysiology.\n\nID: 42515140\nTitle: PFOS Exposure Triggers NRF2-Mediated Senescence in Bone Marrow Mesenchymal Stem Cells to Attenuate Their Chondrogenic Potential.\nAbstract: The widespread application of per- and polyfluoroalkyl substances (PFASs) has established perfluorooctanesulfonic acid (PFOS), a representative PFAS, as a critical environmental pollutant. Although PFOS exposure causes significant bioaccumulation and potential myelotoxicity, its specific impact on the chondrogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) remains to be elucidated. In this study, we established a murine model of PFOS exposure to isolate primary BMSCs and investigated this issue through in vitro differentiation assays, cellular senescence evaluations, and an in vivo subcutaneous implantation model using gelatin methacryloyl (GelMA) hydrogel scaffolds. Our results demonstrated that PFOS exposure triggered intracellular reactive oxygen species (ROS) accumulation and induced a senescent phenotype in BMSCs, characterized by restricted cellular proliferation and the release of senescence-associated secretory phenotype (SASP) factors, thereby markedly suppressing their chondrogenic capacity. Mechanistically, the inhibition of the Nrf2 signaling pathway by PFOS was identified as the principal driver of this process. Furthermore, both in vitro and in vivo assays confirmed that pharmacological activation using the Nrf2 agonist sulforaphane (SFN) effectively mitigated the senescent phenotype and restored the chondrogenic potential of PFOS-exposed BMSCs. Altogether, these findings elucidate the specific mechanisms of PFOS-induced stem cell toxicity and offer a potential strategy to overcome the resulting limitations in BMSC-based cartilage regeneration.\n\nID: 42494618\nTitle: Mechanism of Action and Therapeutic Potential of Sulforaphane in Skeletal Muscle Diseases: Molecular Pathways and Precision Medicine.\nAbstract: Sulforaphane (SFN), a bioactive isothiocyanate abundant in cruciferous vegetables, has attracted growing interest as a potential nutraceutical intervention for skeletal muscle disorders. This narrative review synthesizes preclinical and early clinical evidence on the mechanisms and therapeutic applicability of SFN in ICU-acquired weakness, diabetic myopathy, sarcopenia, and exercise-induced muscle damage. SFN modulates skeletal muscle pathophysiology through four interconnected axes: regulation of protein homeostasis via mTOR-associated signaling and suppression of ubiquitin-proteasome-mediated catabolism; upregulation of oxidative stress defenses through Nrf2-driven antioxidant enzyme induction; attenuation of inflammatory networks via NF-\u03baB inhibition and promotion of M2 macrophage polarization; and metabolic reprogramming through AMPK-mediated mitochondrial biogenesis and enhanced insulin sensitivity. Preclinical data suggest preliminary protective effects on respiratory and locomotor muscle; however, clinical translation remains uncertain. Several randomized controlled trials have failed to demonstrate significant effects on Nrf2 target genes or metabolic stress biomarkers, and bioavailability varies markedly across formulations and individuals. Heterogeneous responses across muscle fiber types, an undefined therapeutic window, and interindividual variability in gut microbiota-mediated conversion further complicate clinical application. To address these challenges, we propose a conceptual \"Sulforaphane Precision Medicine Framework\" integrating molecular biomarkers, gut microbiome profiling, and dynamic delivery systems to guide personalized intervention. While SFN shows promise as an adjunctive therapy, standardized formulations, refined patient stratification, and rigorous phase III trials are essential before routine clinical adoption can be recommended.\n\nID: 42487586\nTitle: Naotaifang Formula Suppresses Ferroptosis by Ameliorating Mitochondrial Biogenesis Through the Nrf2/TFAM Pathway in Ischemic Stroke.\nAbstract: This study aimed to investigate whether activating the Nrf2/TFAM pathway boosts mitochondrial biogenesis, reduces ferroptosis in ischemic stroke (IS), and evaluates Naotaifang (NTF) formula's therapeutic potential. Ferroptosis and mitochondrial biogenesis indicators were measured at various time points following MCAO. Various methods, including transmission electron microscopy, immunofluorescence assay, enzyme-linked immunosorbent assay, Western blotting assays, and real-time quantitative reverse transcription polymerase chain reaction (RT-qPCR), were employed to evaluate the impact of NTF on mitochondrial biogenesis and ferroptosis in vivo and in vitro. IS significantly inhibits mitochondrial biogenesis and increases neuronal ferroptosis, with brain damage worsening over time. MCAO groups showed reduced expression of Nrf2, TFAM, ATP, CISD2, FPN, GPX4, SOD, and HO-1, alongside elevated Fe\u00b2\u207a, ROS, and LPO (P < 0.05) compared to the control group. Both sulforaphane and NTF treatment reversed these effects; NTF treatment effectively increased the expression of Nrf2, TFAM, FtMt, CISD1, CISD2, FPN, and GPX4 while inhibiting the levels of Fe2+, ROS, and LPO. (P < 0.05). This finding clarifies mitochondrial biogenesis's crucial role, proposes a new \"pathway + molecule\" strategy for IS treatment, and supports NTF's clinical potential, though larger animal models and long-term safety studies are needed. In the context of IS, reduced mitochondrial biogenesis plays an important role in ferroptosis. Targeting the Nrf2/TFAM signaling pathway may improve mitochondrial biogenesis in IS. Furthermore, NTF can mitigate ferroptosis by promoting mitochondrial biogenesis through the Nrf2/TFAM signaling pathway.\n\nID: 42473985\nTitle: Emerging Promise of Sulforaphane in Autism: A Comprehensive Review of Its Therapeutic Potential and Mechanisms.\nAbstract: Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder that emerges in early childhood and significantly impacts the quality of life for individuals and families. Currently, there are no specific medications available for ASD. Increasing attention is now focused on bioactive compounds with anti-inflammatory and antioxidant properties. Sulforaphane (SFN), a key member of the isothiocyanate family, is abundant in cruciferous vegetables. It exhibits potent antioxidant and anti-inflammatory effects with minimal side effects, while oxidative stress and inflammation are recognized triggers in ASD pathogenesis. As research deepens, SFN's physiological activities\u2500including antioxidant, neuroprotective, and anti-inflammatory properties are gaining heightened attention. Building on prior studies, this review comprehensively summarizes seven potential pathways through which SFN protects neurodevelopment or reverses ASD-related neural damage, including Keap1/Nrf2/ARE; MAPKs; NF-\u03baB; HSR; AhR/CYP1; Sirtuin-FOXO; and mTOR/autophagy signaling pathways, elucidating the potential mechanisms underlying its multifaceted actions. This review offers new insights for the comprehensive utilization of sulforaphane and the treatment of ASD.\n\nID: 42465275\nTitle: Environmentally relevant depleted uranium exposure damages mitochondria, decreases cytosolic reductive capacity, and increases global DNA damage accumulation through a ROS-independent mechanism involving slingshot protein phosphatase 1b enrichment.\nAbstract: Depleted uranium (DU) is an environmental contaminant with a 30 \u00b5g/L (ppb; parts per billion) EPA maximum contaminant level (MCL) for drinking water. The mining of uranium and use of DU in modern weapons underly human exposure that disproportionally impacts military and tribal communities in the United States. Uranium's radiotoxic characteristics are understood, but its chemical hazards much less so. In zebrafish ( Danio rerio ) and human cell cultures we test the hypothesis that exposure to DU negatively impacts cellular function and development through disruption of mitochondrial metabolism. Using a novel shrapnel model with TEM/SEM+EDS, we showed uranium microparticles caused proximity-dependent mitochondrial disruption. In waterborne exposure paradigms, larval movement was reduced and hatching delayed as a result of reduced movement and not enzyme deficiencies in response to 18 ppb DU, below the MCL. Increased DNA damage accumulation was detected in exposed larva and cells. DNA-damage quantitative PCR of DU-exposed larvae showed increased damage in the ahr1 locus (nuclear gene) and decreased mitochondrial DNA (mtDNA) copy number, but mtDNA damage levels varied across experiments. Mitochondrial function was assessed using a resazurin-based assay in the presence and absence of antioxidants and showed diminished cytoplasmic reductive capacity. DU exposure alone did not enrich antioxidant gene expression, contrasting with arsenic exposure, a known ROS-inducer and Nrf2-activator. Sulforaphane (SFN), a potent Nrf2-activator, did not blunt the effects of DU exposure, despite activation of antioxidant response element (ARE) genes ( gstp and gss) , but did blunt the effects of arsenic exposure. The most enriched transcript in DU-exposed larvae coded for slingshot protein phosphatase ( ssh ), further exploration revealed ssh1b as the zebrafish-specific ortholog activated in response to DU, and inhibition using an identified SSH1 inhibitor, Sennoside A, partially rescued the metabolic and hatching defects observed. Our data points to a cytotoxic mechanism in which DU disrupts mitochondrial function through ssh1b enrichment that impairs normal mitophagy, leading to decreased cellular reductive potential independent of either ROS production or ARE-activation. Our results suggest that health impacts from DU exposure may be directly linked to impaired mitochondrial functions.\n\nID: 42445252\nTitle: A curriculum-integrated learning experience linking experimental pharmacology, cell culture and Nrf2-related gene expression analysis in undergraduate biotechnology education.\nAbstract: Undergraduate biotechnology education requires integrated, experiential approaches that help students connect pharmacological modulation, cellular models, molecular analysis and data interpretation within coherent biological problems. This study describes and evaluates a curriculum-integrated learning experience linking experimental pharmacology, cell culture and Nrf2-related gene expression analysis in third-year Biotechnology students. A total of 32 students participated in the survey-based evaluation. The activity used A549 cells, sulforaphane as an Nrf2-activating compound and tert-butyl hydroperoxide as a pro-oxidant stimulus. Students followed an integrated workflow combining treatment design, cell culture handling, Nrf2-related gene selection, PCR-based gene expression analysis and scientific writing. Perceived learning was assessed using paired pre-post Likert-scale items and analyzed with the Wilcoxon matched-pairs signed-rank test. Post-intervention perceptions, satisfaction and open-ended feedback were analyzed descriptively. Students showed significant improvements in all five pre-post items assessing perceived confidence or familiarity (p value < 0.0001). The proportion of students showing improvement ranged from 81.3% to 100%. Post-intervention responses indicated positive perceptions of interdisciplinary integration, technical competencies, digital competencies, data interpretation and research/professional development.

Aim of this review is to update the knowledge of Nrf2 as neuroprotective agent of PD. Activation of Nrf2, a transcription factor that regulates the expression of antioxidant and cytoprotective genes, has emerged as a promising therapeutic strategy for PD. Nrf2 is a master regulator of the cellular antioxidant response and is responsible for activating the expression of genes that encode antioxidant enzymes such as superoxidedismutase, catalase, and glutathione peroxidase. Pharmacological agents such as sulforaphane, curcumin, and resveratrol have been shown to activate Nrf2 and upregulate the expression of antioxidant genes in preclinical PD models. Clinical trials are currently underway to evaluate the efficacy of these pharmacological agents in patients with PD. While the neuroprotective role of Nrf2 in PD holds great promise for the development of novel therapies, there are several challenges and limitations that need to be addressed in order to harness the full potential of this pathway in the clinic. Overcoming these obstacles will require interdisciplinary collaborations, innovative research approaches, and a greater understanding of the complex pathophysiology of PD. By addressing these challenges, we can move closer to developing effective neuroprotective therapies that can slow or stop the progression of PD and improve the quality of life for patients with this devastating disease.\n\nID: 42426148\nTitle: Multitarget therapeutic potential of sulforaphane in ethidium bromide-induced neurotoxicity in multiple sclerosis-like pathology: comparison with omaveloxolone and dimethyl fumarate on neuroprotection and systemic recovery.\nAbstract: Multiple sclerosis (MS) is a chronic autoimmune disorder characterized by demyelination, neuroinflammation, and neurodegeneration. This study investigates the neuroprotective potential of Sulforaphane (SFN) in ameliorating ethidium bromide (EBRM)-induced MS-like pathology in Wistar rats. The efficacy of SFN at two doses (SFN1.5 and SFN3) was compared to FDA-approved Nrf2 activator drugs, omaveloxolone (OMV15) and dimethyl fumarate (DIMF50). EBRM administration caused neurobehavioral deficits, demyelination, oxidative stress, axonal degeneration, and inflammation. It disrupted key cellular pathways, including Nrf2/HO-1/SIRT-1, JAK/STAT-3/mTOR, and BACE-1/Gamma-secretase/MAPT, as well as caused neurotransmitter imbalances. SFN3 demonstrated significant improvement in motor function, cognitive performance, neurotransmitter levels antioxidant enzymes and alleviated neuroinflammation by modulating inflammatory cytokines. Molecular analyses showed that SFN3 increased Nrf2/HO-1/SIRT-1 levels while decreased pro-inflammatory and neurodegenerative markers such as STAT-3, mTOR, and BACE-1 levels. Gross pathological, Histopathological, and LFB studies indicated reduced demyelination and liver damage. SFN3 also demonstrated favourable systemic safety compared to OMV15. While DIMF50 showed the highest overall efficacy, SFN3 showed consistent modulation of pathological markers, neuroprotective effects, and safety profile. These findings suggest that SFN3 may have therapeutic potential for further translational research in MS. Future studies should validate its clinical relevance and explore combinatorial therapies with existing MS treatments to enhance therapeutic outcomes.\n\nID: 42413380\nTitle: \u03b2-sitosterol and next-generation neuroprotection for multi-target strategies and the gut-brain axis in neurodegenerative diseases.\nAbstract: Neurodegenerative disorders such as Alzheimer's and Parkinson's diseases arise from complex interactions among oxidative stress, neuroinflammation, metabolic dysfunction, and dysregulated signaling networks. This review aim of the synthesize mechanistic evidence on \u03b2-sitosterol as a multi-target phytochemical and clarify how its actions connect to gut-brain axis modulation in neurodegeneration. The integrated mechanistic framework linking \u03b2-sitosterol's effects on cholesterol homeostasis, neuroinflammation, mitochondrial function, cholinergic signaling, and microbiota-barrier integrity to cognitive outcomes. Scope: preclinical and early translational evidence on \u03b2-sitosterol alone and with complementary phytochemicals, including nano-delivery strategies. Increasing evidence highlights phytochemicals as promising multi-target therapeutic agents capable of modulating these interconnected pathological processes. \u03b2-Sitosterol exhibits broad activity by regulating cholesterol metabolism, suppressing neuroinflammation, restoring redox balance, preserving mitochondrial function, and inhibiting important Alzheimer's diseases targets, including acetylcholinesterase and butyrylcholinesterase. The mechanisms action of \u03b2-sitosterol may (i) dampen microglial activation via TLR4/NF-\u03baB signaling, (ii) activate Nrf2-dependent antioxidant responses (Nrf2/HO-1), (iii) support mitochondrial function and reduce ROS, (iv) stabilize membrane cholesterol and modulate amyloidogenic processing, and (v) inhibit acetylcholinesterase/butyrylcholinesterase to restore cholinergic tone. Complementary showing a neuroprotective effect actions of other phytochemicals such as curcumin, resveratrol, sulforaphane, and sinapic acid further enhance neuroprotection by modulating pathways like Nrf2/HO-1, TLR4/NF-\u03baB, PI3K/Akt, and autophagy. Collectively, preclinical studies demonstrate that diverse botanical extracts significantly improve cognitive performance, reduce amyloid burden, restore cholinergic function, and attenuate neuroinflammation and oxidative damage. Emerging preclinical evidence suggests in rodent models of amyloid pathology, \u03b2-sitosterol (5-50\u202fmg/kg) has been reported to improve memory in behavioral tests and reduce markers of neuroinflammation and oxidative stress; gut-brain effects include microbiota remodeling and enhanced barrier integrity, which correlate with reduced neuroimmune activation. Advances in nano-delivery systems and functional food formulations substantially improve phytochemical stability, bioavailability, and brain targeting. Available evidence is chiefly preclinical; clinical translation will require standardized dosing, pharmacokinetic and blood-brain barrier penetration studies, and randomized trials with microbiome and cognitive endpoints. Collectively, these findings position phytochemicals as promising candidates for multi-target disease modification and the development of next-generation neurotherapeutic strategies.\n\nID: 42407371\nTitle: Mupirocin-mediated downregulation of claudin-14 enhances chemosensitivity in human colorectal cancer cells.\nAbstract: Claudin-14 (CLDN14), a tight junction protein, contributes to cell proliferation and chemoresistance in human colorectal cancer (CRC)-derived DLD-1 cells. However, small molecules targeting CLDN14 remain unexplored. Here, we identified mupirocin (MUP), a clinically approved topical antibiotic, as a modulator of CLDN14 protein expression. Quartz crystal microbalance analysis revealed interaction between MUP and recombinant CLDN14 protein with a dissociation constant (Kd) of 2.59\u00a0\u00b1\u00a00.54\u00a0\u03bcM. MUP did not alter CLDN14 mRNA levels but reduced CLDN14 protein stability. Pharmacological inhibition of clathrin-mediated endocytosis and lysosomal degradation significantly reversed the MUP-induced reduction of CLDN14 protein. These results suggest MUP accelerates endocytosis-lysosomal degradation of CLDN14 protein. Other antibiotics failed to decrease CLDN14 expression. Functionally, MUP increased paracellular permeability to mineral ions and enhanced the transepithelial flux of doxorubicin (DXR), an anthracycline anticancer drug, and lucifer yellow, an aqueous small compound. In DLD-1 spheroids, MUP reduced intracellular oxidative stress and nuclear factor erythroid 2-related factor 2 (Nrf2) expression. Consequently, MUP promoted intracellular accumulation of DXR and significantly potentiated its cytotoxic effects in spheroids. Moreover, MUP enhanced the antitumor efficacy of other chemotherapeutic agent oxaliplatin. Sulforaphane, an Nrf2 activator, attenuated the MUP-induced enhancement of anticancer efficacy. These findings suggest that MUP enhances anticancer drug sensitivity in CRC through lysosome-dependent downregulation of CLDN14 protein and suppression of oxidative stress signaling.\n\nID: 42359648\nTitle: Sulforaphane attenuates cisplatin\u2011induced acute kidney injury by inhibiting oxidative stress, inflammation and apoptosis via regulation of NRF2.\nAbstract: Cisplatin\u2011induced acute kidney injury (CI\u2011AKI) is one of the most common comorbidities in patients undergoing chemotherapy, notably limiting the clinical use of cisplatin. However, the pathogenesis of CI\u2011AKI remains to be fully elucidated. Sulforaphane (SFN), a NRF2 agonist, exhibits anti\u2011inflammatory, antioxidant and anti\u2011apoptotic effects, thus SFN exerts protective effects in kidney injury diseases. However, the possible role and underlying mechanisms of SFN in CI\u2011AKI remain ambiguous. An in vivo model of CI\u2011AKI was constructed using C57BL/6 mice that were administered a single intraperitoneal cisplatin injection (20 mg/kg) and conditionally treated with SFN (10 mg/kg). Serum creatinine (Scr) and blood urea nitrogen (BUN) levels were detected by biochemical analysis. Western blotting was performed to assess the expression of renal injury markers, as well as the apoptosis\u2011related proteins cleaved caspase\u20113, caspase\u20113, Bax and Bcl\u20112. Furthermore, hematoxylin and eosin and periodic acid\u2011Schiff staining were employed to detect renal tissue lesions in mice, and TUNEL staining was used to evaluate the apoptosis of renal tissues in each group in vivo. Immunohistochemistry was used to assess the expression of inflammatory marker F4/80 in mouse renal tissues, and ELISA was used to detect the expressions of the inflammatory markers IL)\u20111\u03b2, IL\u20116 and tumor necrosis factor\u2011\u03b1 (TNF\u2011\u03b1) in the serum of mice in each group. DCFH\u2011DA) analysis was used to detect reactive oxygen species (ROS) levels and biochemical analysis was used to evaluate the expression levels of malondialdehyde, superoxide dismutase and glutathione. Finally, western blotting and immunohistochemistry were performed to evaluate the expression of NRF2. An in vitro model of CI\u2011AKI was constructed using HK\u20112 cells induced by cisplatin (10 \u00b5g/ml) that were conditionally treated with one or both of SFN (5 \u00b5M) and the NRF2 inhibitor ML385 (1.9 \u00b5M). Reverse transcription\u2011quantitative PCR was performed to evaluate the expression of NRF2. Cell Counting Kit\u20118 assay was performed to assess the viability of HK\u20112 cells in different groups, whereas flow cytometry was used to assess the apoptosis of HK\u20112 cells in different groups. DCFH\u2011DA analysis was performed to evaluate the expression of ROS in different treatment groups. Furthermore, ELISA was used to evaluate the expressions of IL\u20111\u03b2, IL\u20116 and TNF\u2011\u03b1 in each group. SFN notably decreased the serum levels of Scr and BUN and decreased the expression levels of kidney injury molecule\u20111 and neutrophil gelatinase\u2011associated lipocalin in the cisplatin\u2011induced model group. Histopathological examination revealed attenuated renal structural damage and preserved tubular architecture in the SFN intervention group. Furthermore, SFN notably inhibited the apoptosis, inflammation and oxidative stress of renal tissues induced with cisplatin. Additionally, SFN markedly upregulated NRF2. In vitro, the NRF2 inhibitor ML385 partially attenuated the effects of SFN on the viability, apoptosis, inflammation and oxidative stress of HK\u20112 model cells. The present study indicated that SFN exerted its nephroprotective effect through NRF2\u2011mediated anti\u2011inflammatory, antioxidant and anti\u2011apoptotic mechanisms, positioning SFN as a promising therapeutic candidate for clinical management of chemotherapy\u2011associated kidney injury.\n\nID: 42346630\nTitle: Sulforaphane as a Photoprotective Agent Against UV-Induced Skin Damage and Carcinogenesis: A Scoping Review.\nAbstract: Background/Objectives: Ultraviolet (UV) radiation is a major environmental carcinogen responsible for skin damage through oxidative stress, DNA damage, and inflammation. The nuclear factor erythroid 2-related factor 2 (Nrf2) pathway plays a central role in regulating cellular antioxidant defences against UV-induced damage. This scoping review aims to evaluate the potential role of sulforaphane (SFN), a known Nrf2 inducer, in protecting against UV-induced skin damage and photocarcinogenesis. Methods: A literature search was conducted in PubMed and Scopus from inception to 27 January 2026, to identify original experimental studies investigating SFN, glucoraphanin, or broccoli sprout extracts in the context of UV-induced skin damage. Eligible studies included in vitro, ex vivo, in vivo, and human models assessing outcomes related to oxidative stress, inflammation, molecular signalling pathways, and tumour development. Following screening and eligibility assessment, twelve studies were included in the qualitative synthesis. Results: The included studies suggest that SFN exerts photoprotective effects across multiple experimental models. In murine studies, SFN and SFN-rich extracts were associated with a reduction in tumour incidence, multiplicity, and volume following UV exposure. In human studies, topical SFN application reduced UV-induced erythema and induced cytoprotective enzyme expression, although clinical evidence remains limited. Mechanistically, SFN consistently activated the Nrf2 pathway, leading to increased expression of antioxidant and phase II detoxifying enzymes, and was associated with modulation of inflammatory responses and inhibition of MAPK/AP-1 signalling. Emerging evidence also indicates potential effects on UV-induced metabolic and epigenetic alterations. Conclusions: Current evidence supports a potential role for sulforaphane in mitigating UV-induced skin damage through activation of endogenous defence pathways. However, the available data are predominantly preclinical, and further well-designed clinical studies are needed to clarify its efficacy and translational relevance in humans.\n\nID: 42620616\nTitle: PRRSV suppresses ER-phagy through Nsp2- and Nsp5-mediated degradation of FAM134B.\nAbstract: Porcine reproductive and respiratory syndrome virus (PRRSV) is a significant pathogen in the swine industry that causes reproductive failure in sows and respiratory distress in pigs of all ages, leading to substantial economic losses globally. PRRSV manipulates host cellular processes, particularly those associated with endoplasmic reticulum (ER) function. ER-phagy plays a crucial role in maintaining ER homeostasis and enabling cellular adaptations to stress. Whether and how PRRSV modulates ER-phagy remains incompletely understood. ER-phagy was monitored by western blotting for free mCherry from the mCherry-Sec61B reporter. FAM134B mRNA and protein levels were examined by RT-qPCR and western blotting, respectively. All 12 PRRSV Nsps were screened for FAM134B-suppressing activity by co-transfection, followed by western blotting. Co-immunoprecipitation (Co-IP) was performed to assess interactions between candidate Nsps and FAM134B, as well as their impact on FAM134B- microtubule-associated proteins light chain 3 (LC3) binding. Viral replication was evaluated by RT-qPCR targeting ORF7 and TCID50 assays. We investigated the interplay between PRRSV and ER-phagy and discovered that PRRSV suppresses ER-phagy during the late stages of infection. Further analysis revealed that PRRSV employs its Nsps to inhibit the expression of FAM134B. Specifically, PRRSV Nsp2 and Nsp5 interact with FAM134B, promote its degradation and disrupt its binding to microtubule-LC3, thereby impairing ER-phagy. Collectively, our findings uncover a novel viral strategy to subvert host ER-phagy and provide new insights into PRRSV pathogenesis.\n\nID: 42607684\nTitle: ER-liquid condensate contacts sequester FAM134B/C and RhoA to govern cell morphology.\nAbstract: Endoplasmic reticulum (ER)-phagy receptors have elusive physiological functions beyond ER remodeling. To gain insight into these, we screen for cytoplasmic interactors of well-known receptors in mouse pancreatic ductal adenocarcinoma cells. Our data subsequently reveal a non-canonical action of PRKAR1A, a subunit of protein kinase A (PKA), in binding and activating FAM134B/C. At a molecular level, an amphipathic helix in the otherwise-disordered C terminus of FAM134B directly binds PRKAR1A dimers. Multimodal imaging reveals that this interaction occurs at interorganellar contact sites between the ER and liquid-like condensates of PRKAR1A. Mechanistically, ER-condensate contacts promote clustering of FAM134B/C with LC3B and recruit lysosomes, forming degradation hubs. Unexpectedly, these structures are found to control cytoplasmic signaling through FAM134B/C-mediated lysosomal sequestration of RhoA. Underscoring the physiologic relevance of this, these cytoplasmic-facing actions of FAM134B/C result in RhoA-dependent cell morphologic and migratory control in response to cyclic AMP (cAMP) stimuli. Thus, interorganellar contacts expand the roles of FAM134B/C ER-phagy receptors beyond ER degradation.\n\nID: 42576627\nTitle: Senecavirus a 3C protease cleaves RETREG1 to antagonize ER-phagy and promote viral replication via endoplasmic reticulum calcium signaling.\nAbstract: Co-evolution between viruses and autophagy has led to the emergence of viral strategies that manipulate host endoplasmic reticulum (ER) homeostasis, ultimately promoting viral replication. ER turnover is achieved through selective autophagy, also referred to as ER-phagy, which is regulated by the RETREG1/FAM134B (reticulophagy regulator 1) family of reticulon proteins. Nevertheless, how viruses target RETREG1, a receptor for ER-phagy, remains largely unclear. In this study, we demonstrate that infection with Senecavirus A (SVA), an emerging picornavirus, triggers the cleavage of RETREG1, which functions as a negative regulator of viral replication. By screening viral proteins, we identified the SVA 3C protease (3C[pro]) as the executor of this cleavage event. Detailed mapping revealed that residues Q428, E430, and G431 of RETREG1 are involved in its cleavage by the 3C[pro], and the resulting two fragments fail to suppress viral replication. Furthermore, proteolytic cleavage of RETREG1 by 3C[pro] impairs its ability to relieve ER stress and mediate ITPR1 degradation via RETREG1-dependent ER-phagy. This disruption leads to increased ER calcium (Ca2+) release and subsequent activation of autophagy through the CAMKK2-PRKAA2-MTOR axis, which ultimately facilitates SVA replication. Taken together, these findings indicate that SVA antagonizes the antiviral function of RETREG1-mediated ER-phagy via its 3C[pro], highlighting RETREG1 as a potential therapeutic target for combating SVA infection.Abbreviations: 2-APB: 2-aminoethyl diphenylborinate; PRKAA2/AMPK: protein kinase AMP-activated catalytic subunit alpha 2; ATL3: atlastin GTPase 3; BHK-21: baby hamster kidney-21; CAMKK2: calcium/calmodulin dependent proteinkinase kinase2; CCPG1: cell cycle progression 1; CKAP4/CLIMP63: cytoskeleton associated protein 4; co-IP: co-immunoprecipitation; CQ: chloroquine; DAPI: 4',6-diamidino-2-phenylindole; DM: double mutant; EIF2AK3/PERK: eukaryotic translation initiation factor 2 alpha kinase 3; eGFP: enhanced green fluorescent protein; ER: endoplasmic reticulum; GFP: green fluorescent protein; HSPA5/GRP78/BiP: heat shock protein family A (Hsp70) member 5; HA: hemagglutinin; HDAC4: histone deacetylase 4; HEK-293T: human embryonic kidney 293T; hpi: hours post-infection; IFA: indirect immunofluorescence assay; ITPR1/IP3R1: inositol 1,4,5-trisphosphate receptor type 1; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; LIR: LC3-interacting region; mCherry: monomeric cherry; MTOR: mechanistic target of rapamycin kinase; REEP5: receptor accessory protein 5; RETREG1/FAM134B: reticulophagy regulator 1; RTN3: reticulon 3; SD: standard deviation; SEC61B: SEC61 translocon subunit beta; SEC62: SEC62 preprotein translocation factor; SERP1/RAMP4: stress associated endoplasmic reticulum protein 1; siRNA: small interfering RNA; SQSTM1/p62: sequestosome 1; ST: swine testis; SVA: Senecavirus A; TEM: transmission electron microscopy; TEX264: testis expressed 264, ER-phagy receptor; Tm: tunicamycin; U2OS: human osteosarcoma epithelial cells; UV: ultraviolet; ZVAD-FMK: benzyloxycarbonyl-Val-Ala-Asp(OMe)-fluoromethylketone; \u03bcg: microgram; \u03bcm: micrometer; \u03bcM: micromole.\n\nID: 42491593\nTitle: The role of endoplasmic reticulum stress-mediated autophagy in cadmium-induced liver injury in rats.\nAbstract: Cadmium (Cd) is a widespread toxicant with high bioaccumulation potential. This study explores the interplay of endoplasmic reticulum stress (ERS), autophagy, and apoptosis in Cd-induced hepatotoxicity, focusing on whether ERS-driven autophagy protects against liver injury. Male SD rats (4\u202fweeks old, n\u202f=\u202f24) were acclimatized for 7\u202fdays and randomized into four groups receiving CdCl\u2082 at doses of 0, 0.5, 1, or 2\u202fmg/kg for 14 consecutive days. A second cohort (n\u202f=\u202f36) was similarly allocated to six groups: control, Cd, 4-PBA, Cd\u202f+\u202f4-PBA, CQ and Cd\u202f+\u202fCQ. All treatments were administered via daily intraperitoneal injection throughout the study. On day 14, blood and liver tissues were collected for analyses of liver function, hematological parameters, and histopathology. The expression of target factors was analyzed via qRT-PCR and Western blotting. Results indicate that Cd exposure causes liver injury and disordered hepatocyte morphology. ERS markers Grp78 and Caspase-12 and autophagy-related factors Beclin-1, Atg5, P62 and LC3 are upregulated at both mRNA and protein levels. The endoplasmic reticulum-phagy (ER-phagy) receptor FAM134B and the apoptosis effector cleaved Caspase3 are upregulated at the protein level. These findings indicate that Cd induces ERS, UPR activation, autophagy, reticulophagy, and apoptosis. The ERS inhibitor 4-PBA markedly attenuated Cd-induced hepatic injury. Compared with the Cd group, the Cd\u202f+\u202f4-PBA group showed decreased serum ALT and AST levels, as well as reduced RBC, WBC, MCH, and MCV counts. At the molecular level, mRNA and protein expression of ER stress markers Grp78, Caspase-12, PERK, eIF2\u03b1, ATF4, IRE1\u03b1, JNK, and ATF6 were all downregulated. Protein levels of the ER-phagy receptor FAM134B and the apoptosis effector cleaved Caspase-3 were also decreased. The autophagy inhibitor CQ aggravated such injury. Compared with the Cd group, the Cd\u202f+\u202fCQ group showed increased serum ALT and AST levels, as well as elevated RBC, MCH, and MCV counts. At the protein level, expression of the autophagy-related factors P62 and LC3, and the apoptosis effector cleaved Caspase-3 was significantly increased. These results show that Cd-induced ERS activates autophagy and reticulophagy mainly via the PERK, IRE1\u03b1, and ATF6 pathways, and this adaptive response clears autophagic substrates to alleviate hepatocyte damage.\n\nID: 42369899\nTitle: Second-Generation of Deuterium-Substituted Glutamate Uptake Enhancers Exhibit Superior Drug-Like Properties in Preclinical Evaluation.\nAbstract: Strategic deuterium-hydrogen exchange applied to the first-in-class positive allosteric modulators (PAMs) of the glutamate transporter EAAT2/GLT-1, ( R )-AS-1 and ( R )-AS-7, yielded novel analogues with improved drug-like properties. Specifically, incorporation of deuterium into the pyrrolidine-2,5-dione ring significantly prolonged the elimination half-life and increased both plasma and brain exposure in mice. These enhancements translated into more sustained antiseizure activity and a more favorable pharmacokinetic/pharmacodynamic (PK/PD) relationship. Similar to their nondeuterated counterparts, the new deuterated analogues displayed broad-spectrum antiseizure efficacy across multiple in vivo mouse seizure models, including maximal electroshock (MES), 6 Hz (32/44 mA), acute pentylenetetrazole (PTZ), and PTZ-induced kindling. Among these compounds, d 6 -( R )-AS-7 demonstrated the most robust antiseizure effects and the most advantageous overall pharmacokinetic profile following both intraperitoneal and oral administration. Mechanistic studies revealed that d 6 -( R )-AS-7 markedly enhanced glutamate uptake in COS-7 cells expressing EAAT2 as well as in primary astrocyte cultures. Furthermore, electrophysiological recordings in acute mouse hippocampal slices, together with two-electrode voltage-clamp recordings in Xenopus laevis oocytes expressing EAAT2, confirmed increased transporter-mediated currents. Collectively, these findings identify d 6 -( R )-AS-7 as a potent EAAT2 PAM with improved pharmacokinetic properties and strong antiseizure efficacy, supporting its further development as a therapeutic candidate for epilepsy and other disorders associated with glutamate excitotoxicity.\n\nID: 42343845\nTitle: [Trillium tschonoskii Maxim saponin protects neurological function in rats with post-stroke cognitive impairment by promoting ER-phagy].\nAbstract: To investigate the mechanism that mediates the neuroprotective effects of Trillium tschonoskii Maxim (TTM) against post-stroke cognitive impairment (PSCI) in rats. Adult SD rats were randomized into Sham operation, PSCI model, TTM, rapamycin (an autophagy inducer), 3-methyladenine (an autophagy inhibitor), and TTM+3-MA groups, and rat models of cognitive impairment were established using a modified thread occlusion method. Cognitive function of the rats was assessed using Morris water maze test. Histopathological changes, neuronal apoptosis, dendritic spines, and protein expressions of FAM134B, LC3, ATG5, P62, GRP78, Bax, Bcl-2, IL-10, IL-1\u03b2, and TNF-\u03b1 were evaluated using HE, Nissl, TUNEL, Golgi staining, immunohistochemistry, immunofluorescence staining, and Western blotting. Compared with the sham-operated rats, the rat models of PSCI showed significantly prolonged escape latency, reduced target quadrant time and platform crossings, severe hippocampal damage, increased ATG5 and GRP78 expression, elevated apoptosis, increased IL-1\u03b2, TNF-\u03b1, Bax, GRP78, and P62 expressions, and decreased IL-10, Bcl-2, and LC3 expressions, with slightly increased FAM134B-LC3 and calnexin-LC3 co-localization. Compared with those in the model group, the rats receiving TTM treatment showed significantly shortened escape latency, increased target quadrant time and platform crossings, increased ATG5 and dendritic spines, decreased GRP78 expression, enhanced FAM134B-LC3 and calnexin-LC3 co-localization, reduced IL-1\u03b2, TNF-\u03b1, Bax, GRP78, and P62 expressions, and increased FAM134B, ATG5, LC3, IL-10, and Bcl-2 expressions; the rats treated with 3-MA showed the opposite changes. Excessive ER stress is activated early after stroke, shifting from adaptive to pro-apoptotic signaling, with insufficient ER-phagy flux. TTM modulates ER-phagy, alleviates ERS, reduces neuroinflammation and apoptosis, protects dendritic spines, and improves cognitive function in rats with PSCI. \u76ee\u7684:

42318785\nTitle: Cholesterol-driven sequestration of RETREG1/FAM134B regulates ERphagy and STING1 innate immunity.\nAbstract: The endoplasmic reticulum (ER) is a hub for several essential functions, including lipid metabolism, macroautophagy/autophagy, and innate immune signaling. Excess ER generated during a stress response is degraded by a selective type of autophagy known as ERphagy/reticulophagy. A recent study provides a mechanism by which cholesterol levels regulate ERphagy, STING1 activation, and cholesterol biosynthesis. Elevated ER cholesterol levels suppress ERphagy by reducing RETREG1/FAM134B interactions with the autophagy-related protein MAP1LC3/LC3 and the lysosomal protein LAMP2. The study shows that cholesterol directly binds to RETREG1 and SCAP, facilitating the formation of the RETREG1-SCAP complex. Sequestration of RETREG1 in this manner prevents it from performing its ERphagy functions. Furthermore, RETREG1 also interacts with STING1 and is important for its activation in response to viral infections. SCAP-RETREG1 complex formation also reduces the STING1 response. Thus, this study links lipid metabolism, innate immunity, and autophagy, emphasizing a central role for cholesterol in these processes.\n\nID: 42295516\nTitle: Loss of the ER-cargo protein CLN8 increases severity of acute pancreatitis and upregulates ER-stress and ER-phagy.\nAbstract: Acute pancreatitis is caused by a premature activation of digestive proteases. One hypothesis is based on the proteolytic activation of the serine protease trypsinogen by the lysosomal enzyme cathepsin B (CTSB) after co-localization in the same subcellular compartment. The ER-cargo receptor protein CLN8 (ceroid lipofuscinosis, neuronal) mediates cathepsin transport from the endoplasmic reticulum (ER), the site of enzyme synthesis, to the trans-Golgi system, from which they are distributed to their final destinations. The aim of this study is to investigate the role of CLN8 in acute pancreatitis and intracellular cathepsin trafficking by using isolated pancreatic acinar cells, a CLN8-deficient (Cln8mnd/MsrJ) mouse model, and 266-6 mouse pancreatic acinar tumor cells in which the Cln8 gene was inactivated by CRISPR/Cas9. Loss of CLN8 mitigated the early phase of acute pancreatitis but did not prevent it completely. We still observed CTSB expression in the endo-lysosomal and secretory compartment albeit enzyme activation was decreased. At later disease stages pancreatic injury increased along with an upregulation of ER-phagy shown by an overexpression of LC3B and the ER-phagy receptor FAM134B as well as autophagolysosome formation and increased ER stress. In summary, our data show that acute pancreatitis still occurs despite disruption of the EGRESS (ER-to-Golgi relaying of enzymes of the lysosomal system) complex implicating alternative intracellular enzyme delivery routes. They also illustrate that ER-stress and ER-phagy aggravate severity at later course of pancreatitis.\n\nID: 42274906\nTitle: Environmental Factors Drive Neurodegenerative Diseases Through Glutamate Excitotoxicity: A Convergent Mechanistic Pathway.\nAbstract: This review illustrates how environmental stressors disrupt glutamate homeostasis via specific mechanisms: lead-induced thiol modification, manganese mediated yin yang 1 (YY1)-histone deacetylases (HDAC) repression, PM2.5-triggered microglia-astrocyte crosstalk, and advanced glycation end products (AGEs)-receptor for advanced glycation end products (RAGE)-nuclear factor kappa-B (NF-\u03baB) signaling from high-sugar diets. Together with genetic susceptibility and pigment epithelium-derived factor (PEDF), these factors impair astrocytic glutamate uptake, promoting synaptic glutamate accumulation. Subsequent N-methyl-D-aspartate (NMDA) and \u03b1-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid (AMPA) receptor overactivation triggers calcium overload, mitochondrial dysfunction, oxidative stress, and neuroinflammation-termed \"degenerative excitotoxicity\". Excitotoxicity manifests in Alzheimer's disease (amyloid-beta-excitatory amino acid transporter 2 (EAAT2) interplay), Parkinson's disease (subthalamic nucleus-driven excitatory storm), and amyotrophic lateral sclerosis (astrocytic failure versus neuronal cell-autonomous mechanisms). Future interventions need multi-target strategies, emerging technologies, and lifestyle modifications. This convergent framework offers a unified understanding linking environmental exposure to neurodegeneration and charts a roadmap toward mechanism-based prevention and treatment.\n\nID: 42192129\nTitle: FAM134B-mediated ER-phagy degrades APP and suppresses Alzheimer's disease pathology.\nAbstract: Endoplasmic reticulum autophagy (ER-phagy) is a selective autophagy pathway in which receptor proteins target ER membranes and proteins for degradation, yet its role in Alzheimer's disease (AD) remains unclear. Here, we identify FAM134B/RETREG1 as a specific ER-phagy receptor mediating amyloid precursor protein (APP) degradation. FAM134B directly interacts with ER-localized wild-type and familial mutant APP via their C-terminal domains and recruits LC3 through its LC3-interacting region (LIR) to promote APP delivery to phagophores for lysosomal degradation. In AD, epigenetic silencing at the FAM134B promoter suppresses its transcription by limiting TFEB/TFE3 binding despite their nuclear enrichment. This transcriptional suppression impairs ER-phagy, leading to APP accumulation and exacerbated AD pathology. AAV-mediated hippocampal expression of wild-type, but not LIR-mutant, FAM134B in 5XFAD mice restores ER-phagy, enhances APP clearance, reduces A\u03b2 deposition, preserves synaptic and myelin integrity, and improves cognitive performance. These findings establish FAM134B downregulation as an upstream pathogenic event in AD, suggesting ER-phagy enhancement as a promising strategy to suppress A\u03b2 generation at its source.\n\nID: 42161229\nTitle: ER-phagy drives resistance to mitochondria-targeted therapy in breast cancer.\nAbstract: Endoplasmic reticulum stress and ER-phagy are emerging regulators of cancer cell adaptation to metabolic and oxidative stress, yet their integration with mitochondrial dysfunction remains poorly understood. Here, we identify ER-phagy as a previously unrecognized adaptive response to ISOXUS, an isoxazole derivative of usnic acid with selective anticancer activity. ISOXUS, a mitochondrial respiratory complex II inhibitor, induces bioenergetic collapse, reactive oxygen species accumulation, and extensive ER-derived vacuolization. Using integrated transcriptomic and metabolomic analyses, we demonstrate that ISOXUS selectively triggers ER-phagy in mitochondria-dependent MCF-7 breast cancer cells, but not in more glycolytic triple-negative MDA-MB-231 cells, revealing a cell-type-specific stress adaptation program. ER-phagy induction is associated with upregulation of the ER-phagy receptor FAM134B and depends on ER stress signalling, as pharmacological ER stress inhibition suppresses this process. Multi-omics profiling uncovers coordinated repression of mitochondrial gene expression together with activation of ER-centered metabolic pathways, including amino acid metabolism, the tricarboxylic acid cycle, and one-carbon folate metabolism. Notably, we also identify UFMylation-related genes (CDK5RAP3, DDRGK1) as novel candidates involved in ER-phagy induced by ISOXUS. Moreover, mitochondrial inhibitors, rotenone and oligomycin, unexpectedly promote, while antioxidant a-tocopherol blocks ISOXUS-induced ER-phagy, and all compounds partially improve cell viability under ISOXUS treatment, implicating ROS-driven ER-phagy as a cytoprotective mechanism. Integrated analyses further reveal activation of the integrated stress response (ISR), dominated by the PERK-ATF4 axis, driving glutamine-dependent metabolic reprogramming and suppression of apoptosis-related pathways. The late-stage autophagy inhibition lowered the glutathione synthesis after ISOXUS treatment. Collectively, our findings uncover a previously unappreciated mitochondria-ER-ISR axis that governs metabolic adaptation to ISOXUS and identifies ER-phagy as a potential therapeutic vulnerability in breast cancer.\n\nID: 42144055\nTitle: IFITM3 knockout alleviates neuronal parthanatos by restoring astrocytic glutamate uptake in intracerebral hemorrhage mice.\nAbstract: Intracerebral hemorrhage (ICH) causes severe neurological deficits mainly attributable to secondary brain injury. Parthanatos is a subtype of regulated cell death triggered by glutamate excitotoxicity. Interferon-induced transmembrane protein 3 (IFITM3) is an immune regulatory molecule involved in neuronal death in various neurodegenerative disorders. However, it remains unclear whether and how IFITM3 and parthanatos participate in secondary brain injury after ICH. This study aims to investigate whether IFITM3 aggravates neuronal parthanatos by impairing astrocytic glutamate uptake after ICH and to elucidate the underlying mechanisms. Bioinformatics analysis of transcriptome datasets from ICH human patients and mouse models was performed to identify the IFITM3 expression and its potential functions. IFITM3 knockout mice and mice with AAV-mediated astrocytic IFITM3 overexpression were subjected to the ICH model by autologous blood injection. Neurobehavioral tests, Western blot, immunofluorescence staining, glutamate uptake assay, and pharmacological approaches were employed to elucidate the role of IFITM3 in glutamate uptake and neuronal parthanatos. IFITM3 was upregulated and served as a hub gene in immune response and cell death after ICH. IFITM3 knockout improved the sensorimotor and cognitive functions of ICH mice. Conversely, astrocytic IFITM3 overexpression reversed these neuroprotective effects. Specifically, IFITM3 knockout alleviated neuronal excitotoxicity and parthanatos by restoring astrocytic glutamate uptake in the perihematomal region, as evidenced by decreased glutamate levels, oxidative damage, PARP-1 overactivation, PAR overproduction, and nuclear translocation of the AIF-MIF complex. Additionally, IFITM3 knockout reduced p38 MAPK phosphorylation and increased the expression of glutamate transporter EAAT2. Administration of a p38 MAPK inhibitor in IFITM3-overexpressing mice restored EAAT2 expression and attenuated neuronal parthanatos after ICH. Astrocytic IFITM3 upregulation causes impaired glutamate uptake, excitotoxicity, parthanatos, and neurological deficits through p38 MAPK/EAAT2 pathway, highlighting IFITM3 and parthanatos as potential therapeutic targets for ICH.\n\nID: 42128064\nTitle: Disruption of hippocampal synaptic plasticity by chronic ethanol exposure: A narrative review of neurotoxic adverse outcome pathways.\nAbstract: Chronic is a major neurotoxicant that disrupts hippocampal synaptic plasticity, leading to persistent cognitive deficits. This narrative review maps the adverse outcome pathways (AOPs) through which ethanol impairs synaptic function, primarily via interconnected cascades: TLR4/NF-\u03baB-mediated neuroinflammation (triggering microglial activation and pro-inflammatory cytokines TNF-\u03b1, IL-1\u03b2), CYP2E1-driven oxidative stress (generating ROS/RNS, 4-HNE, causing protein carbonylation and mitochondrial dysfunction), and glutamate excitotoxicity (mediated by GluN2B-NMDAR subunit shifts, Ca\u00b2\u207a overload, and astrocytic EAAT2/GLT-1 downregulation). These pathways converge to suppress BDNF/TrkB signaling (via miR-206 and impaired proBDNF cleavage), leading to deficits in synaptic protein synthesis (e.g., Arc) and trafficking (e.g., GluA1 endocytosis via STEP, impaired forward trafficking). Critically, these insults potentiate neuronal apoptosis through intrinsic (ROS/mitochondrial permeabilization, caspase-9/-3) and extrinsic (TNF-\u03b1/TNF-R1, caspase-8) pathways, executing irreversible synaptic loss via caspase-3 cleavage of PSD-95, spectrin, and cytoskeletal collapse. The structural consequences-dendritic simplification, reduced mature spine density, and PSD-95 nano-domain disorganization-manifest functionally as attenuated LTP, potentiated mGluR-LTD, and impaired STDP. This synaptic decay directly underpins cognitive impairments in pattern separation, contextual memory, and cognitive flexibility. Neuroinflammation (TLR4/NF-\u03baB) acts as a central amplifier, linking oxidative damage, excitotoxicity, and BDNF collapse to apoptotic synaptic deletion. Future research must address dose-dependency, subfield vulnerability, epigenetic regulation, and therapeutic strategies targeting TLR4, TrkB, mitochondrial antioxidants, and anti-apoptotic pathways.\n\nID: 42107477\nTitle: Nano-selenium attenuates cadmium-induced ER-phagy through inhibition of TFEB nuclear translocation and FAM134B downregulation.\nAbstract: Cadmium (Cd) is a well-documented environmental pollutant associated with male reproductive disorders, necessitating the urgent development of effective therapeutic agents. Nano-selenium (Nano-Se) represents an advanced selenium supplement with robust antioxidant properties, which can mitigate various forms of heavy metal toxicity. However, the role of Nano-Se in alleviating Cd-induced testis damage remains unclear. Family with sequence similarity 134 member B (FAM134B) is the first identified Endoplasmic reticulophagy (ER-phagy) receptor, and the ER-phagy it mediates plays a crucial role in the reproductive system. In this study, Hy-line White roosters were randomly divided into four groups and subjected to a 90-day observation period. Serum samples and testicular tissue samples from roosters were collected for subsequent detection. Hematoxylin-eosin (H&E) staining, periodic acid-Schiff (PAS) staining, ELISA kit detection, Western blotting (WB), immunofluorescence (IF), cellular thermal shift assay (CETSA) and molecular docking techniques were employed to explore the effects of Cd on the reproductive system and the alleviating effect of Nano-Se. In vivo assays revealed that Nano-Se efficiently mitigated testicular atrophy and histological damage triggered by Cd exposure. Nano-Se reversed the Cd-mediated inhibition of steroidogenesis-related proteins, and elevated the expression of Leydig cell markers including 3\u03b2-HSD and INSL3, thereby ameliorating Cd-evoked Leydig cell dysfunction. Consistent with in vivo outcomes, in vitro tests using primary rooster Leydig cells demonstrated that Nano-Se notably restrained Cd-activated ER-phagy and excessive lysosomal acidification. Mechanistically, such protective effects were achieved by blocking TFEB nuclear translocation and preventing the downregulation of FAM134B. This present study provides a foundation for preclinical research for its usefulness as a potential therapeutic for reproductive toxicity induced by environmental heavy metal pollutants.\n\nID: 42104568\nTitle: PACS2 Alleviates Sepsis-Induced Myopathy by Activating ERK-MAPK Signalling Pathway to Suppress ER-Phagy.\nAbstract: Sepsis-induced myopathy (SIM) is a common and life-threatening complication, but its underlying mechanisms remain poorly understood. PACS2, a key resident protein at mitochondria-associated endoplasmic reticulum membranes (MAMs), regulates ER homeostasis under various pathological conditions. However, whether sepsis disrupts PACS2-dependent MAM integrity, thereby triggering ER dysfunction and muscle wasting, remains unexplored. We established a sepsis mouse model via cecal ligation and puncture (CLP) and assessed muscle function using compound muscle action potential (CMAP) recording and grip strength measurements. Muscle atrophy was evaluated by H&E staining and Western blotting. PACS2 expression was determined by Western blotting, immunohistochemistry and qRT-PCR. MAM integrity was assessed by immunofluorescence co-localization of IP3R and VDAC1, and ER-phagy (reticulophagy) activation was evaluated by transmission electron microscopy, Western blotting and fluorescence microscopy. To investigate the functional role of PACS2, adeno-associated virus (AAV)-mediated PACS2 overexpression was performed in mouse tibialis anterior muscle and gastrocnemius muscles, followed by RNA-sequencing analysis. The MAPK pathway proteins p-ERK, p-P38 and p-JNK levels were assessed by Western blotting, and the involvement of ERK-MAPK signalling was tested pharmacologically via intraperitoneal injection of the ERK inhibitor SCH772984. Septic mice developed progressive skeletal muscle atrophy (p\u2009<\u20090.001) and dysfunction (p\u2009<\u20090.01), accompanied by 56% reduction in PACS2 expression at 96\u2009h post-CLP (p\u2009<\u20090.01), 25% decrease in MAM integrity (p\u2009<\u20090.05) and subsequent activation of FAM134B-mediated ER-phagy (p\u2009<\u20090.01). AAV-mediated PACS2 overexpression significantly alleviated muscle atrophy by restoring MAM integrity by 28% (p\u2009<\u20090.01), reducing FAM134B expression by 43% (p\u2009<\u20090.01) and attenuating ER-phagy (p\u2009<\u20090.01). Co-immunoprecipitation revealed no detectable direct protein-protein interaction between PACS2 and FAM134B. Transcriptome sequencing and Western blotting analysis demonstrated that PACS2 overexpression specifically activated the ERK-MAPK signalling pathway (55% increase in p-ERK, p\u2009<\u20090.01) without affecting p-P38 or p-JNK levels (p>0.05), which suppressed FAM134B-mediated ER-phagy (p\u2009<\u20090.05) and ameliorated muscle atrophy (p\u2009<\u20090.05) by inhibiting nuclear translocation of TFEB (p\u2009<\u20090.01). Pharmacological ERK inhibition with SCH772984 abolished the protective effects of PACS2 by promoting TFEB nuclear translocation (p\u2009<\u20090.001) and TFEB-mediated FAM134B expression (p\u2009<\u20090.001). Our findings demonstrate that SIM is closely associated with disrupted MAM integrity. PACS2 plays a critical role in maintaining MAM structural integrity and regulating FAM134B-mediated ER-phagy through the ERK-MAPK-TFEB signalling axis, thereby providing novel mechanistic insights and potential therapeutic targets for SIM.\n\nID: 42051019\nTitle: Multi-Target Neuroprotective Compound Exhibits EAAT2-Modulating and Alzheimer's Pathology-Attenuating Effects in In Vitro and In Vivo Models.\nAbstract: Alzheimer's disease (AD) is a debilitating neurodegenerative disorder characterized by cognitive decline and memory loss. Current treatments offer limited efficacy, necessitating the development of innovative multitarget therapeutic strategies. Here, we present N3,N5-bis(2-(5-methoxy-1H-indol-3-yl)ethyl)-2,6-dimethyl-4-(2-nitrophenyl)pyridine-3,5-dicarboxamide (HCM-01), a novel compound developed to target multiple neurodegenerative pathways implicated in AD. In vitro assays included MTT-based cell viability analyses performed in two complementary experimental settings: primary neuronal cultures and astrocyte-based in vitro cell culture models exposed to glutamate. In primary hippocampal neuronal cultures, glutamate exposure induced a statistically significant reduction in cell viability compared with vehicle-treated controls, consistent with glutamate-induced excitotoxicity. Under these conditions, HCM-01 treatment resulted in a statistically significant improvement in neuronal viability, showing a greater protective effect compared with donepezil and memantine. In contrast, in astrocyte-based in vitro cultures, the applied glutamate concentration did not induce overt cytotoxicity, in line with the intrinsic neuroprotective and glutamate-buffering role of astrocytes. Accordingly, astrocytic experiments were designed to assess functional modulation of glutamate-handling mechanisms rather than cell survival. Western blot analysis in C8-D1A astrocytic cells demonstrated increased expression of excitatory amino acid transporter 2 (EAAT2) following HCM-01 treatment compared with control and reference drug-treated groups, suggesting modulation of astrocyte-mediated glutamate homeostasis. In parallel, redox analyses revealed that HCM-01 improved oxidative/antioxidative balance, as evidenced by increased total antioxidant capacity (TAC) and reduced total oxidant status (TOS), supporting an indirect antioxidant contribution to its functional effects. In vivo behavioral assessment of HCM-01 in a streptozotocin (STZ)-induced Alzheimer's model in female Sprague-Dawley rats demonstrated that administration of HCM-01 at doses of 50 mg/kg orally (oral, P.O. and intraperitoneal, I.P.) and 100 mg/kg (P.O.), significantly improved cognitive and memory functions in the passive avoidance (PA), Morris water maze (MWM), and locomotor activity tests. Moreover, histopathological and immunohistochemical analyses of different hippocampal regions revealed reduced neuronal damage, attenuation of tau pathology, antiamyloidogenic effect, and restoration of cholinergic function. Complementary in silico studies, including molecular docking, molecular dynamics simulations (MDS), and free energy calculations, suggested potential interactions of HCM-01 with the allosteric site of EAAT2. Taken together, these findings suggest that HCM-01 exerts neuroprotective effects against glutamate-induced excitotoxicity in primary hippocampal neurons while additionally modulating glutamatergic homeostasis and redox balance through functional mechanisms in astrocyte-based models, supporting its relevance as a multitarget preclinical candidate for early stage AD mechanisms.\n\nID: 41953939\nTitle: FAM134B isoform 2/RETREG1-2 defines a calnexin-TOLLIP-coupled ER-phagy pathway that restricts Ebola virus glycoprotein and is antagonized by VP40 through macro-autophagy.\nAbstract: Selective autophagy of the endoplasmic reticulum (ER-phagy) is critical for ER proteostasis and host defense, yet how ER quality-control pathways interface with ER-phagy to restrict viral glycoproteins remains poorly defined. Previously, the 1st known ER-phagy receptor gene RETREG1 (RETR1)/FAM134B gene was reported to restrict Ebola virus (EBOV) replication in vivo by inhibiting the viral glycoprotein (GP) and viral protein 40 kDa (VP40) expression, but this mechanism remains unknown. Here, we identify the truncated RETR1/FAM134B isoform 2 (RETR1-2), but not its full-length protein RETR1, as an ER-phagy receptor that targets EBOV-GP for degradation. RETR1-2 broadly triggers GP degradation across ebolavirus species but not Marburg virus and inhibits EBOV replication. Mechanistically, RETR1-2 recognizes EBOV-GP via its luminal domain, undergoes GP-induced oligomerization, and directs GP-containing ER membranes to lysosomes through canonical macro-autophagy. Using unbiased mass spectrometry, we identified TOLLIP as the key cytoplasm adaptor for RETR1-2, which also requires cooperation with the ER chaperone calnexin for EBOV-GP degradation. Notably, the PI3P-binding C2 domain of TOLLIP mediates its interaction with RETR1-2, and the EBOV-GP degradation occurs independently of ubiquitination, revealing an unexpected role for TOLLIP in ER-phagy. Furthermore, EBOV-VP40 antagonizes this pathway by selectively targeting RETR1-2 for macroautophagic degradation independently of TOLLIP, thereby restoring GP expression and viral infectivity. Nevertheless, RETR1-2 reciprocally degrades VP40 via a similar mechanism. Together, these findings define a calnexin-TOLLIP-RETR1-2 axis that links ER quality control to ER-phagy-mediated antiviral restriction and uncover a reciprocal host-virus arms race centered on selective macro-autophagy.\n\nID: 41932312\nTitle: Mechanosensory channels mediate ER Ca2+ transients to trigger assembly of autophagosome initiation sites for degradation of ER subdomains.\nAbstract: ER-phagy involves the selective autophagosomal engulfment of ER fragments, but the signaling events, selection mechanisms, and membrane source of ER-phagic autophagosomes remain elusive. Here, using state-of-the-art super-resolution multi-SIM imaging, we reveal that stresses (prolonged starvation, cholesterol dyshomeostasis, and high-Ca2+ insults) trigger the expansion of sheet ER subdomains containing high levels of luminal Ca2+ in mammalian cells, which are subsequently degraded by ER-phagy. Autophagosome formation and sequestration of ER sheets require the concerted actions of FAM134B and lipidated LC3, whereas the autophagy proteins ATG14 and ATG9 are partially dispensable. Electron microscopy and cryo-electron tomography show that the membranes of autophagosomes enclosing high-Ca2+-containing ER sheets are directly remodeled from the ER. The ER-localized cation channels PIEZO1 and TRPV1 are enriched at and mediate Ca2+ transients from high-Ca2+-containing ER sheets, triggering liquid-liquid phase separation of the autophagosome-initiating FIP200 complex to initiate ER-phagy. Thus, distinct mechanisms are employed for the formation of high-Ca2+-containing ER-enclosing autophagosomes and non-selective autophagosomes.\n\nID: 41844133\nTitle: IRE1/FAM134B-mediated ER-phagy alleviates zearalenone-induced ER stress and developmental defects in porcine embryos.\nAbstract: Zearalenone (ZEN), a mycotoxin commonly found in animal feed, impairs the female reproductive function owing to its estrogen-mimicking ability. ZEN exposure induces endoplasmic reticulum (ER) stress, oxidative stress, and autophagy activation. However, the involvement of inositol-requiring enzyme 1 (IRE1)-mediated ER-phagy in ZEN-induced ER stress and embryonic competence during in vitro culture (IVC) remains unclear. Porcine embryos were cultured with 2.5, 5, and 10\u202f\u03bcM ZEN for two days after in vitro fertilization (IVF) to assess blastocyst development. ZEN exposure caused a significant dose-dependent decrease in blastocyst formation, expanded blastocysts, and total cell number (p\u202f<\u202f0.05). ZEN-treated embryos exhibited increased DNA fragmentation along with elevated mitochondrial and intracellular Ca\u00b2\u207a levels (p\u202f<\u202f0.001), as confirmed using terminal deoxynucleotidyl transferase dUTP nick-end labeling assay and Rhod-2 and Fluo-4 AM staining. ER-tracker analysis revealed decreased ER fluorescence intensity and increased uneven cytoplasmic ER distribution in blastocysts exposed to 5 and 10\u202f\u03bcM ZEN (p\u202f<\u202f0.001). Western blotting showed activation of the unfolded protein response (UPR) with increased expression of glucose-regulated protein 78 (GRP78), p-IRE1, IRE1, p-c-Jun N-terminal kinase (JNK), JNK, C/EBP homologous protein (CHOP), and the autophagy marker microtubule-associated protein 1 light chain 3 beta (LC3B) (p\u202f<\u202f0.05), whereas the ER-phagy receptor family with sequence similarity 134, member B was downregulated. Tauroursodeoxycholic acid (TUDCA) alleviated ZEN-induced ER stress, restoring ER distribution and calcium homeostasis, reducing DNA damage, and improving blastocyst development. These findings suggest that ZEN disrupts IRE1 signaling and suppresses ER-phagy during early porcine embryo development, whereas TUDCA alleviates ER stress and improves embryonic competence during IVC.\n\nID: 41812815\nTitle: Harmine and its derivatives: A promising multi-target therapeutic avenue for Alzheimer's disease.\nAbstract: Alzheimer's disease (AD) is a complex neurodegenerative disorder characterized by \u03b2-amyloid (A\u03b2) deposition, tau hyperphosphorylation, neuroinflammation, and cholinergic dysfunction. Currently, no disease-modifying drugs are available, and existing symptomatic treatments offer limited efficacy while posing safety concerns, highlighting the urgent need for multi\u2011target therapeutic strategies. The natural \u03b2\u2011carboline alkaloid harmine has attracted considerable attention due to its favorable blood-brain barrier penetration and multi\u2011target profile. Accumulating preclinical evidence indicates that harmine can concurrently modulate several core pathological processes of AD. Mechanistically, it potently inhibits dual\u2011specificity tyrosine phosphorylation\u2011regulated kinase 1A (DYRK1A), thereby reducing tau hyperphosphorylation, suppressing aberrant amyloid precursor protein processing, and enhancing neprilysin\u2011mediated A\u03b2 clearance. Concurrently, harmine attenuates neuroinflammation via negative regulation of the Toll-like receptor 4 (TLR4)/nuclear factor kappa B (NF\u2011\u03baB) and NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome pathways, improves cholinergic neurotransmission through acetylcholinesterase inhibition, and alleviates glutamate excitotoxicity by upregulating astrocytic glutamate transporter 1/excitatory amino acid transporter 2 (GLT-1/EAAT2) expression. Structurally optimized harmine derivatives have demonstrated enhanced dual inhibitory activity and improved cognitive outcomes in preclinical models. Despite these promising findings, challenges such as pharmacokinetic limitations, insufficient target selectivity, and a lack of clinical data remain. In conclusion, the harmine scaffold represents a mechanistically grounded and promising direction for the development of multi\u2011target therapeutics for AD.\n\nID: 41797117\nTitle: T-2 toxin induces ER stress-dependent liver injury via mitophagy-mediated ER-phagy suppression: Berbamine blocks SNARE complex for hepatoprotection.\nAbstract: T-2 toxin is a persistent, bioaccumulative environmental contaminant that poses major health threats to humans and animals. Endoplasmic reticulum (ER) stress and autophagy are two interconnected stress responses critical for maintaining cellular homeostasis. Berbamine (BBM) is an important member of bis-benzy lisoquinoline alkaloid with diverse biological activities. This study aimed to identify the molecular target of BBM against T-2 toxin-induced hepatotoxicity, focusing on autophagy-ER stress crosstalk. We systematically evaluated autophagy and ER stress in human HepaRG cells using immunoblotting, transmission electron microscopy and an autophagy reporter assay. T-2 toxin was found to concurrently activate PINK1/Parkin-mediated mitophagy and suppress Keap1-mediated FAM134B ubiquitination-dependent ER-phagy, thereby triggering ER stress. Integrated evidence from molecular dynamics and western blot demonstrated that BBM upregulated and stabilized BNIP3, blocking the VAMP8-SNAP29 interaction to inhibit T-2 toxin-induced autophagy and subsequent ER stress. Moreover, in vivo mouse experiments demonstrated that 30\u202fmg/kg BBM significantly alleviated T-2 toxin-induced liver injury by suppressing both autophagic flux and ER stress; BBM significantly reduced serum levels of liver enzymes, ALT, and AST. Collectively, our findings elucidate a novel mechanism wherein T-2 toxin-induced mitophagy inhibits ER-phagy to drive ER stress-mediated liver injury and highlight the therapeutic potential of BBM in alleviating T-2 toxin-induced liver injury.\n\nID: 41784832\nTitle: Crocin Mitigates Glutamate Excitotoxicity and Tau Hyperphosphorylation by Modulating EAAT2 and Akt/Tau Pathway in a Scopolamine-induced Rat Model of Alzheimer's Disease.\nAbstract: Alzheimer's disease (AD) is characterized by glutamatergic dysregulation and excitotoxicity, largely associated with impaired activity of the excitatory amino acid transporter 2 (EAAT2). Downregulation of EAAT2 results in glutamate accumulation, N-Methyl-D-Aspartate (NMDA) receptor overactivation, and neuronal injury. Crocin (Cr), a carotenoid compound extracted from saffron (Crocus sativus), exhibits potent antioxidant and neuroprotective properties, particularly in experimental models of neurodegeneration. Forty-eight adult male rats were divided into six groups: control (saline), crocin (50\u00a0mg/kg), scopolamine (3\u00a0mg/kg for 7 days), scopolamine followed by memantine (M) (20\u00a0mg/kg), scopolamine followed by crocin, and scopolamine followed by both memantine and crocin. This study aimed to evaluate the therapeutic potential of crocin, alone and in combination with memantine, in a scopolamine-induced rat model of Alzheimer's disease, with a focus on EAAT2 modulation. Scopolamine administration significantly elevated glutamate, NMDAR and p-tau levels while reducing p-Akt, GABA and EAAT2 levels, accompanied by marked hippocampal neurodegeneration. In contrast, crocin treatment, either alone or in combination with memantine, restored neurotransmitter balance, downregulated NMDAR, upregulated EAAT2, increased p-Akt expression level and reduced tau phosphorylation. Histological analysis further confirmed notable structural recovery of hippocampal neurons.\n\nID: 41661358\nTitle: MARCH6 Confers Protection Against Endoplasmic Reticulum Autophagy in Gliomas by Destabilizing FAM134B.\nAbstract: This study probed the mechanism of MARCH6 in endoplasmic reticulum autophagy (ER-phagy) during glioma development by regulating FAM134B stability. MARCH6 and FAM134B expression levels were measured in glioma tissues. A comparative analysis was conducted on the correlation between clinical parameters and FAM134B expression in 46 glioma patients. FAM134B and MARCH6 were knocked down in glioma cells, followed by detection of cell viability and apoptosis, typical ER stress (ERS) markers (PERK, IRE1\u03b1, eIF2\u03b1, and CHOP), autophagy-related proteins (P62 and LC3B), and autophagosome cytoplasmic accumulation. A mouse glioma model was established for in vivo validation. MARCH6-FAM134B interaction, FAM134B ubiquitination levels, and protein stability were examined. FAM134B expression was high and MARCH6 expression was low in glioma tissues. MARCH6 induced FAM134B protein ubiquitination and degradation, reducing its stability in glioma cells. Knockdown of FAM134B reduced glioma cell survival, inhibited PERK, IRE1\u03b1, eIF2\u03b1, and CHOP expression, decreased LC3I to LC3II conversion, lowered LC3B fluorescence expression, and reduced the accumulation of autophagosomes with continuous ER structures in the cytoplasm, while enhancing apoptosis and P62 expression. This effect can be reversed by knocking down MARCH6. In vivo, FAM134B knockdown suppressed tumorigenesis in mice. MARCH6 exerts a repressive effect on ERS responses and ER-phagy in glioma cells by destabilizing FAM134B.\n\nID: 41593210\nTitle: ER-phagy receptors: structural mechanisms in selective ER degradation and disease implications.\nAbstract: The endoplasmic reticulum (ER) is a central organelle for protein synthesis and folding, lipid metabolism and calcium signaling, etc. To maintain ER homeostasis, cells employ a specific autophagy process termed ER-phagy (reticulophagy), which depredates ER components via three forms: macro-ER-phagy (involving bulk ER sequestration), micro-ER-phagy (lysosome-direct), and ER-to-lysosome-associated degradation (ERLAD). The identification of specific ER-phagy receptors including FAM134A, FAM134B, FAM134C, TEX264, SEC62, RTN3L, CCPG1, ATL3, CALCOCO1 and others has significantly advanced our understanding of ER quality control mechanisms. In this review we summarize the current knowledge on ER-phagy receptors, and emerging evidence linking ER-phagy dysfunction to various disease pathologies including neurological disorders, cancer, metabolic diseases, cardiovascular diseases, infections and immune disorders. Recent evidence shows that ER-phagy receptors can form novel ER-derived structures, such as ER-tubular bodies (ER-TBs) consisted of ATL3 and RTN3L, which mediate Golgi-bypassing unconventional protein secretion under stress conditions, revealing non-degradative functions of these receptors beyond quality control. Targeting ER-phagy receptors may provide insights into potential therapeutic strategies for diseases associated with this fundamental cellular process.\n\nID: 41564102\nTitle: Fecal microbiota transplantation ameliorates radiation-induced lung injury by reshaping gut metabolic homeostasis to activate FAM134B-mediated ER-phagy.\nAbstract: Radiation-induced lung injury (RILI) is a serious complication of thoracic radiotherapy, with limited effective treatment options. This study demonstrates that fecal microbiota transplantation (FMT) confers protection against RILI through modulation of the gut-lung axis. In a total lung irradiation (TLI) mouse model, FMT significantly alleviated pulmonary histopathological injury, inflammatory responses, oxidative stress, and collagen deposition during fibrogenesis. Concurrently, FMT improved intestinal motility, enhanced mucosal barrier integrity, and restored TLI-induced dysbiosis in gut microbiota diversity and community structure. Metabolomic analysis revealed that TLI significantly disrupted the metabolism of unsaturated fatty acids and arachidonic acid (AA), whereas FMT partially restored these metabolic networks. Transcriptomic and ultrastructural analyses indicated that RILI suppressed endoplasmic reticulum (ER) protein processing and induced ER swelling, while FMT promoted protective ER-phagy and facilitated restoration of ER morphology. Integrated multi-omics analysis further identified the AA metabolism as a key component of FMT-mediated protection, with its alterations closely associated with pulmonary tissue repair. Further in vivo and in vitro experiments demonstrated that AA binds to and activates the nuclear receptor PPAR\u03b3, leading to transcriptional upregulation of FAM134B, promoting protective ER-phagy and ameliorating RILI. In summary, this study highlights the bidirectional gut-lung axis as a therapeutic target in RILI progression and intervention, and reveals that FMT confers protection through metabolic remodeling and activation of the PPAR\u03b3-FAM134B-mediated ER-phagy pathway, providing a mechanistic basis for potential clinical translation.\n\nID: 41462664\nTitle: Chronic Stress and Astrocyte Dysfunction in Depression: Molecular Mechanisms and Gene Expression Changes.\nAbstract: Major depressive disorder (MDD) is a complex and heterogeneous psychiatric condition with high global prevalence and significant personal and societal burdens. While traditionally focused on neuronal dysfunction, emerging research highlights a critical role for astrocytes-glial cells essential for maintaining brain homeostasis in the pathogenesis of depression. This review explores how chronic stress, a major risk factor for MDD, disrupts astrocyte function through multiple converging mechanisms. We detail the normal physiological roles of astrocytes in synaptic regulation, neurotransmitter cycling, metabolic support, and neurovascular integrity, and examine how these functions are compromised under chronic stress. Key molecular pathways implicated include glucocorticoid receptor (GR) signaling dysregulation, neuroinflammatory responses, glutamate excitotoxicity, oxidative stress, and epigenetic alterations. Evidence from histological and transcriptomic studies in both human postmortem tissue and rodent models reveals consistent changes in astrocyte-specific genes, such as GFAP, SLC1A2, SLC1A3, BDNF, and AQP4, supporting their involvement in depressive pathology. Finally, we discuss therapeutic strategies targeting astrocyte dysfunction-including EAAT2 upregulation, neuromodulation, anti-inflammatory approaches, GR modulation, and glial-focused epigenetic therapies. Understanding astrocyte pathology in the context of chronic stress not only refines our understanding of MDD but also opens novel avenues for treatment development.\n\nID: 41438769\nTitle: RETREG1/FAM134B-mediated micro-ER-phagy in the retrovirus-SERINC5 arms race.\nAbstract: Reticulophagy regulator 1 (RETREG1)/Family with sequence similarity 134 member B (FAM134B) is a selective endoplasmic reticulum (ER)-phagy receptor that mediates starvation-induced macro-ER-phagy, but whether it participates in other pathways mediating ER turnover has remained unclear. Here, we unveil a previously unrecognized role for RETREG1 in micro-ER-phagy and show how the murine leukemia virus (MLV) accessory protein glycosylated group-specific antigen (glycoGag) exploits this pathway to antagonize the host restriction factor SERINC5 (serine incorporator 5). GlycoGag binds SERINC5 in the endoplasmic reticulum (ER) and selectively recruits RETREG1 to eliminate SERINC5 through an autophagosome-independent process that bypasses ATG3 (autophagy-related), ATG5, ATG7, BECN1 (Beclin-1), LC3 (microtubule-associated protein 1 light chain 3) lipidation, and PIK3C3 (phosphatidylinositol 3-kinase catalytic subunit type 3)/hVPS34 (vacuolar protein sorting 34). RETREG1 knockout abolishes degradation of ER-retained SERINC5, whereas endolysosomal turnover of surface SERINC5 remains partially intact, demonstrating that glycoGag utilizes dual ER-phagy and endolysosomal routes to suppress SERINC5. These findings expand the functional repertoire of RETREG1 in autophagy, identify that retroviruses repurpose micro-ER-phagy to circumvent SERINC5-mediated restriction, and reveal ER-phagy as an understudied battleground in the ongoing arms race between cellular restriction factors and viral accessory proteins.\n\nID: 41413198\nTitle: Inhibition of STING-mediated antiviral innate immunity activation by CD97 via modulation of ER-phagy.\nAbstract: Endoplasmic reticulum (ER) autophagy (ER-phagy) is a vital homeostatic process triggered by multiple signals and plays a crucial role in regulating innate immunity and viral replication. However, the mechanisms by which host proteins utilize ER-phagy to regulate innate immune response during viral infection remains largely unclear. Here, we uncover the regulatory crosstalk between innate immune adapter, ER retention protein Stimulator of Interferon Genes (STING), and the G protein-coupled receptor ADGRE5/CD97 (Cluster of Differentiation 97). Our results demonstrate that CD97 suppresses the STING-mediated type-I interferon (IFN-I) response against DNA virus and cytosolic DNA, thereby promoting herpes simplex virus type 1 (HSV-1) replication in both cells and mice. CD97 facilitates the recruitment of the ER-phagy receptor, FAM134B (family with sequence similarity 134, member B), to initiate ER-phagy, resulting in the degradation of STING subsequent to DNA virus infection. Furthermore, Cd97-deficient mice exhibit higher IFN-I response and greater resistance to HSV-1 infection. Additionally, our findings reveal that inhibiting CD97 with sanguinarine effectively disrupts HSV-1 replication. These findings shed light on the role of CD97 in the innate immune response against DNA virus infections and offer valuable checkpoint for anti-viral STING activation.\n\nID: 42563439\nTitle: Mechanistic pathways linking gut microbial metabolites, microbial structural products, and host-microbe co-metabolites to mitochondrial function.\nAbstract: Gut-derived microbial metabolites modulate host mitochondrial function. To our knowledge, no prior systematic review has synthesized evidence linking these metabolites to direct mitochondrial endpoints across all major metabolite classes. PubMed, Scopus, and Web of Science were systematically searched through March 2026 for studies examining direct mitochondrial endpoints in relation to ten classes of gut-derived metabolites. Gut-derived microbial metabolites exert diverse effects on mitochondrial function, ranging from bioenergetic enhancement to direct toxicity. After contextual evidence was excluded from the certainty assessment, four metabolite-mitochondrial outcome groupings had moderate certainty: butyrate, propionate, indoxyl sulfate, and lipopolysaccharide. Evidence for p-cresyl sulfate, H\u2082S, and urolithin A was rated low; evidence for the remaining metabolite classes was low or very low. Butyrate generally enhances mitochondrial biogenesis, ATP generation, and electron transport chain activity across multiple experimental models. Indoxyl sulfate generally impaired mitochondrial function, whereas p-cresyl sulfate produced concentration- and model-dependent effects. PGC-1\u03b1 emerges as a central regulatory node, integrating microbial metabolic signals to control mitochondrial biogenesis and oxidative metabolism. Many microbial metabolites demonstrate concentration-dependent biphasic effects. These findings support a mechanistic microbiome-mitochondrial framework in which diverse gut-derived molecules converge on a limited set of mitochondrial control nodes: electron transport chain activity, reactive oxygen species handling, biogenesis, and mitophagy. The evidence base is predominantly preclinical; these insights should be considered hypothesis-generating.\n\nID: 42468217\nTitle: Spermidine alleviates 2,2-dichloroacetamide/ 2,2-dibromoacetamide-exposed mouse oocyte toxicity by restoring autophagic homeostasis.\nAbstract: Environmental toxicants pose a major threat to human health, yet the reproductive toxicity of haloacetamide disinfection byproducts remains largely unclear. Here, we examined the effects of two haloacetamides, 2,2-dichloroacetamide (DCAcAm) and 2,2-dibromoacetamide (DBAcAm), on mouse oocyte maturation and identified the underlying mechanisms of toxicity. Both compounds markedly impaired meiotic spindle assembly and compromised the function of multiple organelles, including mitochondria, the endoplasmic reticulum, and the Golgi apparatus, primarily through autophagy dysregulation at specific exposure concentrations, as evidenced by the observation that more than half of the oocytes failed to progress beyond the MII stage. Spermidine supplementation effectively restored autophagic activity and rescued the associated cellular defects, thereby improving both nuclear and cytoplasmic maturation in oocytes. Collectively, these findings demonstrate that spermidine alleviates toxicant-induced deterioration of oocyte quality by regulating autophagy and highlight its potential therapeutic value for reproductive protection and clinical application.\n\nID: 42409519\nTitle: WIPButyrate produced by the Lycium ruthenicum polysaccharide alleviated sleep deprivation-induced chronic fatigue syndrome in mice through promoting microglial autophagy.\nAbstract: This study explored whether Lycium ruthenicum polysaccharide (LRP) influences gut microbiota-derived short-chain fatty acids (SCFAs) and neuroinflammatory responses in a sleep deprivation-induced CFS-like mouse model. Oral LRP was associated with improved fatigue-related behavioral performance, reduced neuronal injury, and better cognitive and motor outcomes. These changes coincided with an increased abundance of putative butyrate-producing bacteria and higher butyrate levels in serum and brain. To examine a possible downstream link, sodium butyrate was tested in cultured microglia and attenuated inflammatory activation while improving mitochondrial stress and autophagy-related readouts. Overall, the data suggest that microbiota-associated butyrate changes may contribute to the observed benefits of LRP, supporting its potential as a food-derived strategy for fatigue-related neuroinflammation.\n\nID: 42331842\nTitle: AOC1 regulates labor initiation through spermidine-induced autophagy of placental trophoblast cells via EIF5A hypusination.\nAbstract: Parturition depends on precise communication between the mother and fetus. While fetal lung signals are known to help initiate labor, the role of the placenta has remained unclear. Here we show that in steroid receptor coactivator (Src)-1 and -2 double-knockout mice, reduced placental amine oxidase, copper-containing 1 (Aoc1) leads to increased spermidine levels. In trophoblast cells, spermidine induces autophagy via hypusination of eukaryotic translation initiation factor 5\u2009A (EIF5A), reducing estrogen and prostaglandin production. Estrogen reciprocally increases Aoc1 expression via estrogen receptor-\u03b1 (ER\u03b1) in concert with SRC-1/2, forming a feedback loop maintaining placental autophagy homeostasis. AOC1 levels are elevated in preterm labor placentas from both mice and humans. Placenta-specific Aoc1 knockout dramatically delays labor by increasing trophoblast autophagy. Importantly, spermidine supplementation rescues inflammation-induced preterm labor in mice. Our findings reveal that placental AOC1-spermidine-EIF5A-autophagy axis is essential for parturition timing and offer a potential therapeutic strategy for preterm birth.\n\nID: 42249092\nTitle: TIA-1 promotes FUNDC1-mediated mitophagy to protect against stress-induced cellular senescence.\nAbstract: Mitochondrial dysfunction, characterized by reduced mitophagy, excessive mitochondrial elongation, and elevated reactive oxygen species production, is a hallmark of cellular senescence. However, the molecular mechanisms linking impairment of redox balance to mitophagy suppression during senescence remain poorly understood. In this study, we identified TIA-1, an RNA-binding protein, as a positive regulator of FUNDC1 expression, a key receptor for ubiquitin-independent mitophagy. Sodium butyrate and ultraviolet-B irradiation triggered oxidative stress-associated senescence in HaCaT cells, leading to reduced TIA-1 expression, decreased FUNDC1 levels, impaired mitophagy flux, excessive mitochondrial elongation, and upregulation of senescence markers. Conversely, ectopic expression of TIA-1 restored FUNDC1 levels, enhanced mitophagy, improved mitochondrial function, and reduced senescence marker expression. Ribonucleoprotein immunoprecipitation assays confirmed that TIA-1 directly interacts with FUNDC1 mRNA, and subsequent analyses indicated that TIA-1 enhances FUNDC1 expression primarily through translational control. Together, these findings establish TIA-1 as a pivotal regulator of mitochondrial homeostasis during cellular stress, acting through FUNDC1 to sustain mitophagy and limit senescence. Targeting TIA-1 may offer new strategies to mitigate mitochondrial dysfunction and restore redox balance in aging and age-related diseases.\n\nID: 42217339\nTitle: Codonopsis pilosula as the sovereign herb in Shenling Baizhu formula ameliorates DSS-induced ulcerative colitis via spermidine-AMPK-mediated mitophagy to inhibit the cGAS-STING inflammatory axis.\nAbstract: Dextran sulfate sodium-induced ulcerative colitis is featured by excessive intestinal inflammation and disrupted mucosal immune homeostasis. Codonopsis pilosula is the sovereign herb in Shenling Baizhu Formula for ulcerative colitis therapy, and Codonopsis pilosula polysaccharides are its key active components, while their immunomodulatory effects and molecular mechanisms in Shenling Baizhu Formula against ulcerative colitis remain elusive. This study explored the critical role of Codonopsis pilosula polysaccharides and the spermidine-AMPK-mediated mitophagy-cGAS-STING inflammatory axis in regulating intestinal inflammation and ameliorating ulcerative colitis. A dextran sulfate sodium-induced ulcerative colitis mouse model was established to evaluate the indispensable role of Codonopsis pilosula polysaccharides in Shenling Baizhu Formula. Ultra-high performance liquid chromatography metabolomics and 16S ribosomal RNA sequencing were performed to identify key metabolites and gut microbiota. In vitro dextran sulfate sodium-induced ulcerative colitis cellular models (human colorectal adenocarcinoma Caco-2 and human normal colonic epithelial NCM460 cells) were constructed to validate the regulatory mechanism of spermidine on AMPK-mediated mitophagy, inflammatory balance and intestinal epithelial injury. Codonopsis pilosula polysaccharides were essential for the anti-ulcerative colitis efficacy of Shenling Baizhu Formula: removal of Codonopsis pilosula significantly aggravated colonic pathological lesions, intestinal inflammatory responses and oxidative stress in ulcerative colitis mice, whereas Codonopsis pilosula polysaccharides supplementation reversed these abnormal phenotypes (P\u00a0<\u00a00.05). Metabolomics and microbiomics confirmed that Codonopsis pilosula polysaccharides exerted therapeutic effects via spermidine (a key metabolite in glutamate metabolism pathway) and Muribaculaceae. Critically, in vitro dual-cell experiments verified that spermidine activated AMPK-mediated mitophagy to directly inhibit the hyperactivation of cGAS-STING inflammatory axis, thereby restoring intestinal inflammatory homeostasis and alleviating epithelial cell injury in ulcerative colitis. Codonopsis pilosula polysaccharides extracted from the sovereign herb Codonopsis pilosula in Shenling Baizhu Formula ameliorate dextran sulfate sodium-induced ulcerative colitis, and the core mechanism depends on spermidine-triggered AMPK-mediated mitophagy to suppress the cGAS-STING inflammatory signaling axis, which plays a pivotal role in regulating intestinal immunity and repairing mucosal epithelial damage.\n\nID: 42045046\nTitle: [Research progress in mechanisms of dietary resistant starch for regulating glucose and lipid metabolism].\nAbstract: The global prevalence of metabolic diseases such as obesity, diabetes, and cardiovascular diseases is closely related to overnutrition and imbalanced dietary patterns. As an important carbohydrate, starch directly affects the homeostasis of glucose and lipid metabolism due to its digestion characteristics. Resistant starch (RS) with unique anti-digestive properties and prebiotic functions has become the current hotspot in dietary nutrition research for improving glucose and lipid metabolism disorders. This review summarizes the digestive characteristics of starch and the comprehensive effects of RS and its mechanisms for ameliorating metabolic diseases. Diets with high RS content not only optimize glucose homeostasis by delaying glucose release, the undigested fractions entering the colon also drive the metabolic regulatory network of the gut microbiota-gut-brain axis by activating the AMPK/ACC pathway to reduce fat accumulation, enhancing intestinal barrier function mediated by short-chain fatty acids (SCFAs), and promoting GLP-1/PYY neural signal transduction. These insights facilitate the design of new healthy foods and inspire new strategies for optimizing dietary nutrition and regulating glucose and lipid metabolism disorders caused by high-carbohydrate diets. \u4ee3\u8c22\u6027\u75be\u75c5\u5982\u80a5\u80d6\u3001\u7cd6\u5c3f\u75c5\u3001\u5fc3\u8840\u7ba1\u75be\u75c5\u7684\u5168\u7403\u6d41\u884c\u4e0e\u8425\u517b\u8fc7\u5269\u53ca\u996e\u98df\u6a21\u5f0f\u5931\u8861\u5bc6\u5207\u76f8\u5173\u3002\u6dc0\u7c89\u4f5c\u4e3a\u4eba\u7c7b\u4e3b\u8981\u80fd\u91cf\u6765\u6e90\u7684\u78b3\u6c34\u5316\u5408\u7269\uff0c\u5176\u6d88\u5316\u7279\u6027\u76f4\u63a5\u5f71\u54cd\u7cd6\u8102\u4ee3\u8c22\u7a33\u6001\u3002\u6297\u6d88\u5316\u6027\u6dc0\u7c89\uff08RS\uff09\u56e0\u5176\u72ec\u7279\u7684\u6297\u6d88\u5316\u7279\u6027\u4e0e\u76ca\u751f\u5143\u529f\u80fd\uff0c\u6210\u4e3a\u5f53\u524d\u6539\u5584\u7cd6\u8102\u4ee3\u8c22\u7d0a\u4e71\u7684\u81b3\u98df\u8425\u517b\u7814\u7a76\u7684\u70ed\u70b9\u3002\u672c\u6587\u7efc\u8ff0\u4e86\u6dc0\u7c89\u6d88\u5316\u7279\u6027\u4ee5\u53caRS\u6539\u5584\u4ee3\u8c22\u6027\u75be\u75c5\u7684\u7efc\u5408\u4f5c\u7528\u53ca\u76f8\u5173\u673a\u5236\u3002\u9ad8RS\u7684\u81b3\u98df\u4e0d\u4ec5\u901a\u8fc7\u5ef6\u7f13\u8461\u8404\u7cd6\u91ca\u653e\u4f18\u5316\u8840\u7cd6\u7a33\u6001\uff0c\u800c\u4e14\u672a\u6d88\u5316\u7684\u90e8\u5206\u8fdb\u5165\u7ed3\u80a0\u901a\u8fc7\u9a71\u52a8\u80a0\u9053\u83cc\u7fa4-\u80a0-\u8111\u8f74\u4ee3\u8c22\u8c03\u63a7\u7f51\u7edc\uff0c\u5176\u4e2d\u5305\u62ec\u6fc0\u6d3b\u817a\u82f7\u9178\u6d3b\u5316\u86cb\u767d\u6fc0\u9176/\u4e59\u9170\u8f85\u9176A\u7fa7\u5316\u9176\uff08AMPK/ACC\uff09\u901a\u8def\u51cf\u5c11\u8102\u80aa\u84c4\u79ef\u3001\u63d0\u5347\u77ed\u94fe\u8102\u80aa\u9178\uff08SCFAs\uff09\u4ecb\u5bfc\u7684\u80a0\u5c4f\u969c\u529f\u80fd\u4e0e\u80f0\u9ad8\u8840\u7cd6\u7d20\u6837\u80bd-1/\u80bdYY\uff08GLP-1/PYY\uff09\u795e\u7ecf\u4fe1\u53f7\u4f20\u5bfc\u3002\u8fd9\u4e0d\u4ec5\u5c06\u4e3a\u65b0\u578b\u5065\u5eb7\u98df\u54c1\u8bbe\u8ba1\u63d0\u4f9b\u7814\u7a76\u57fa\u7840\uff0c\u4e5f\u4e3a\u4f18\u5316\u81b3\u98df\u8425\u517b\uff0c\u8c03\u63a7\u9ad8\u78b3\u6c34\u996e\u98df\u5f15\u8d77\u7684\u7cd6\u8102\u4ee3\u8c22\u7d0a\u4e71\u63d0\u4f9b\u4e86\u65b0\u7684\u7814\u7a76\u601d\u8def\u3002.\n\nID: 42013738\nTitle: Spermidine alleviates sepsis-induced cardiomyopathy by improving mitochondrial quality and quantity via a Metallothionein 1-dependent antioxidant pathway.\nAbstract: Sepsis-induced cardiomyopathy (SICM) is characterized by mitochondrial dysfunction, impaired mitophagic flux, and overwhelming oxidative stress. Spermidine (SPD), a natural polyamine known to enhance autophagy and preserve cardiac function in aging and metabolic disorders, has not been systematically evaluated in the context of septic cardiomyopathy. To determine the therapeutic potential and mechanistic basis of SPD in septic cardiac dysfunction. Network pharmacology, RNA sequencing, a cecal ligation and puncture (CLP) mouse model, and multiple cellular assays were integrated to assess the protective actions of SPD. Mitochondrial function, mitophagy flux, and oxidative stress were evaluated using transmission electron microscopy (TEM), immunohistochemistry (IHC), Western blotting, structured illumination microscopy (SIM), mitochondrial membrane potential assays, oxygen consumption rate (OCR) analysis, and mitochondrial DNA (mtDNA) quantification. Transcriptomic clustering and pathway enrichment identified molecular targets, which were validated through siRNA-mediated gene silencing. SPD markedly attenuated SICM in vivo and in vitro by improving both mitochondrial quantity and quality. It restored sepsis-impaired mitophagy by upregulating LC3B and ATG7, promoting autophagosome maturation, and enhancing cellular ubiquitination. Transcriptomic profiling highlighted metallothionein-1 (MT1) as a key node in metal-ion response pathways. SPD activated the NRF2-MT1-SOD2 antioxidant axis, reduced mitochondrial reactive oxygen species (mtROS) under lipopolysaccharide (LPS) stimulation, and reversed sepsis-induced suppression of SOD2. MT1 knockdown abolished SPD-mediated SOD2 stabilization and mtROS clearance, confirming its essential role in SPD's cardioprotective effects. SPD mitigates SICM by orchestrating the restoration of mitochondrial quality control, normalization of mitophagic flux, and stabilization of cellular redox homeostasis. These findings support SPD as a promising therapeutic candidate for septic cardiomyopathy.\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\u2019s complementary-but-disjoint (A-B-C) model.

Growing evidence shows that metabolites generated along the gut-brain axis regulate neuroinflammation. In this study, we demonstrate that oral administration of sodium butyrate (NaB) (300 or 600\u2009mg/kg/day) for 28 days lowered mortality and lessened neuropathological signs in mice infected with SS2 (SC19 strain). Butyrate prophylaxis was associated with lower bacterial loads in the blood and brain tissue, preserved expression of tight junction proteins (ZO-1, Claudin-5, and Occludin) in the brain, and maintained blood-brain barrier (BBB) integrity and permeability. 16S rRNA sequencing analysis revealed that SC19 infection significantly diminished the diversity and richness of the gut microbiota, notably depleting key short-chain fatty acid (SCFA)-producing bacterial taxa. Butyrate intervention restored microbial homeostasis and enriched SCFA-producing communities. Mechanistically, butyrate was associated with upregulated expression of nuclear factor erythroid 2-related factor 2 (Nrf2) and its downstream antioxidant effectors (heme oxygenase 1 [HO-1] and NQO1), while inhibiting phosphorylation of NF-\u03baB p65 and the secretion of proinflammatory cytokines (interleukin-1\u03b2 [IL-1\u03b2], interleukin-6 [IL-6], and tumor necrosis factor-\u03b1 [TNF-\u03b1]) in human cortical microvessels endothelial cells/D3 (hCMEC/D3) cells. Critically, these protective effects were abrogated upon pharmacological inhibition of Nrf2, indicating the critical role of Nrf2 in butyrate-mediated attenuation of neuroinflammation and oxidative stress. Our findings highlight the prophylactic potential of modulating the gut-brain axis as a novel strategy to mitigate central nervous system (CNS) infections associated with foodborne pathogens.\n --- END ACTUAL ABSTRACT FOR 42610256 ---\n\n- ERROR: You cited ID: 41953939 for the quote: \"Spermidine-mediated FAM134B-dependent ER-phagy...

Previously, the 1st known ER-phagy receptor gene RETREG1 (RETR1)/FAM134B gene was reported to restrict Ebola virus (EBOV) replication in vivo by inhibiting the viral glycoprotein (GP) and viral protein 40 kDa (VP40) expression, but this mechanism remains unknown. Here, we identify the truncated RETR1/FAM134B isoform 2 (RETR1-2), but not its full-length protein RETR1, as an ER-phagy receptor that targets EBOV-GP for degradation. RETR1-2 broadly triggers GP degradation across ebolavirus species but not Marburg virus and inhibits EBOV replication. Mechanistically, RETR1-2 recognizes EBOV-GP via its luminal domain, undergoes GP-induced oligomerization, and directs GP-containing ER membranes to lysosomes through canonical macro-autophagy. Using unbiased mass spectrometry, we identified TOLLIP as the key cytoplasm adaptor for RETR1-2, which also requires cooperation with the ER chaperone calnexin for EBOV-GP degradation. Notably, the PI3P-binding C2 domain of TOLLIP mediates its interaction with RETR1-2, and the EBOV-GP degradation occurs independently of ubiquitination, revealing an unexpected role for TOLLIP in ER-phagy. Furthermore, EBOV-VP40 antagonizes this pathway by selectively targeting RETR1-2 for macroautophagic degradation independently of TOLLIP, thereby restoring GP expression and viral infectivity. Nevertheless, RETR1-2 reciprocally degrades VP40 via a similar mechanism. Together, these findings define a calnexin-TOLLIP-RETR1-2 axis that links ER quality control to ER-phagy-mediated antiviral restriction and uncover a reciprocal host-virus arms race centered on selective macro-autophagy.\n --- END ACTUAL ABSTRACT FOR 41953939 ---\n\n- ERROR: You cited ID: 42359648 for the quote: \"Sulforaphane notably inhibited the apoptosis, inflammation and oxidative stress of renal tissues induced with cisplatin.

However, the pathogenesis of CI\u2011AKI remains to be fully elucidated. Sulforaphane (SFN), a NRF2 agonist, exhibits anti\u2011inflammatory, antioxidant and anti\u2011apoptotic effects, thus SFN exerts protective effects in kidney injury diseases. However, the possible role and underlying mechanisms of SFN in CI\u2011AKI remain ambiguous. An in vivo model of CI\u2011AKI was constructed using C57BL/6 mice that were administered a single intraperitoneal cisplatin injection (20 mg/kg) and conditionally treated with SFN (10 mg/kg). Serum creatinine (Scr) and blood urea nitrogen (BUN) levels were detected by biochemical analysis. Western blotting was performed to assess the expression of renal injury markers, as well as the apoptosis\u2011related proteins cleaved caspase\u20113, caspase\u20113, Bax and Bcl\u20112. Furthermore, hematoxylin and eosin and periodic acid\u2011Schiff staining were employed to detect renal tissue lesions in mice, and TUNEL staining was used to evaluate the apoptosis of renal tissues in each group in vivo. Immunohistochemistry was used to assess the expression of inflammatory marker F4/80 in mouse renal tissues, and ELISA was used to detect the expressions of the inflammatory markers IL)\u20111\u03b2, IL\u20116 and tumor necrosis factor\u2011\u03b1 (TNF\u2011\u03b1) in the serum of mice in each group. DCFH\u2011DA) analysis was used to detect reactive oxygen species (ROS) levels and biochemical analysis was used to evaluate the expression levels of malondialdehyde, superoxide dismutase and glutathione. Finally, western blotting and immunohistochemistry were performed to evaluate the expression of NRF2. An in vitro model of CI\u2011AKI was constructed using HK\u20112 cells induced by cisplatin (10 \u00b5g/ml) that were conditionally treated with one or both of SFN (5 \u00b5M) and the NRF2 inhibitor ML385 (1.9 \u00b5M). Reverse transcription\u2011quantitative PCR was performed to evaluate the expression of NRF2. Cell Counting Kit\u20118 assay was performed to assess the viability of HK\u20112 cells in different groups, whereas flow cytometry was used to assess the apoptosis of HK\u20112 cells in different groups. DCFH\u2011DA analysis was performed to evaluate the expression of ROS in different treatment groups. Furthermore, ELISA was used to evaluate the expressions of IL\u20111\u03b2, IL\u20116 and TNF\u2011\u03b1 in each group. SFN notably decreased the serum levels of Scr and BUN and decreased the expression levels of kidney injury molecule\u20111 and neutrophil gelatinase\u2011associated lipocalin in the cisplatin\u2011induced model group. Histopathological examination revealed attenuated renal structural damage and preserved tubular architecture in the SFN intervention group. Furthermore, SFN notably inhibited the apoptosis, inflammation and oxidative stress of renal tissues induced with cisplatin. Additionally, SFN markedly upregulated NRF2. In vitro, the NRF2 inhibitor ML385 partially attenuated the effects of SFN on the viability, apoptosis, inflammation and oxidative stress of HK\u20112 model cells. The present study indicated that SFN exerted its nephroprotective effect through NRF2\u2011mediated anti\u2011inflammatory, antioxidant and anti\u2011apoptotic mechanisms, positioning SFN as a promising therapeutic candidate for clinical management of chemotherapy\u2011associated kidney injury.\n --- END ACTUAL ABSTRACT FOR 42359648 ---\n\n- ERROR: You cited ID: 42289383 for the quote: \"Spermidine supplementation improved renal function, reduced fibrosis by 75.3%, and decreased senescent regions by 74%.\"\n FACT: Strict Misquote Detected!

Here, we investigated whether the polyamine biosynthetic enzyme S-adenosylmethionine decarboxylase 1 (AMD1) regulates tubular senescence and repair outcomes after AKI and elucidated the underlying mechanism. AMD1 dynamics were examined in an ischemia-reperfusion injury model using male C57BL/6J mice by immunofluorescence. AAV-mediated Ksp promoter-driven tubule-specific Amd1 conditional knockdown male mice (Amd1 cKD) were used to assess renal injury, cell-cycle status, senescence, and remodeling, and exogenous spermidine was administered for rescue. DNA damage signaling and p53/p21 activation were evaluated by immunostaining, Western blotting, and EdU incorporation assays. AMD1 was predominantly expressed in the tubular epithelium, with prominent dynamic induction in proximal tubules early after IRI, but declined to baseline levels during the late phase, representing a relative metabolic insufficiency that correlated inversely with fibrosis. Compared with wild-type controls, Amd1 cKD mice exhibited aggravated tubular injury, an over two-fold increase in SA-\u03b2-gal-positive areas, elevated p21, and reduced Ki67+ proliferation. Conversely, spermidine supplementation improved renal function, reduced fibrosis by 75.3%, and decreased senescent regions by 74%. Mechanistically, AMD1 deficiency increased \u03b3H2AX-marked DNA damage and activated the p53/p21 checkpoint, whereas spermidine attenuated this response and restored DNA synthesis capacity. Collectively, tubular AMD1 acts as a metabolic checkpoint that preserves polyamine homeostasis to restrain p53/p21-dependent senescence, promote adaptive repair after AKI, and spermidine supplementation represents a potential strategy to mitigate maladaptive AKI-to-CKD progression.\n --- END ACTUAL ABSTRACT FOR 42289383 ---\n\n- ERROR: You cited ID: 42217339 for the quote: \"Codonopsis pilosula polysaccharides were essential for the anti-ulcerative colitis efficacy of Shenling Baizhu Formula... via spermidine-triggered AMPK-mediated mitophagy to suppress the cGAS-STING inflammatory signaling axis\"\n FACT: Ellipses (...) are strictly forbidden.

Codonopsis pilosula is the sovereign herb in Shenling Baizhu Formula for ulcerative colitis therapy, and Codonopsis pilosula polysaccharides are its key active components, while their immunomodulatory effects and molecular mechanisms in Shenling Baizhu Formula against ulcerative colitis remain elusive. This study explored the critical role of Codonopsis pilosula polysaccharides and the spermidine-AMPK-mediated mitophagy-cGAS-STING inflammatory axis in regulating intestinal inflammation and ameliorating ulcerative colitis. A dextran sulfate sodium-induced ulcerative colitis mouse model was established to evaluate the indispensable role of Codonopsis pilosula polysaccharides in Shenling Baizhu Formula. Ultra-high performance liquid chromatography metabolomics and 16S ribosomal RNA sequencing were performed to identify key metabolites and gut microbiota. In vitro dextran sulfate sodium-induced ulcerative colitis cellular models (human colorectal adenocarcinoma Caco-2 and human normal colonic epithelial NCM460 cells) were constructed to validate the regulatory mechanism of spermidine on AMPK-mediated mitophagy, inflammatory balance and intestinal epithelial injury. Codonopsis pilosula polysaccharides were essential for the anti-ulcerative colitis efficacy of Shenling Baizhu Formula: removal of Codonopsis pilosula significantly aggravated colonic pathological lesions, intestinal inflammatory responses and oxidative stress in ulcerative colitis mice, whereas Codonopsis pilosula polysaccharides supplementation reversed these abnormal phenotypes (P < 0.05). Metabolomics and microbiomics confirmed that Codonopsis pilosula polysaccharides exerted therapeutic effects via spermidine (a key metabolite in glutamate metabolism pathway) and Muribaculaceae. Critically, in vitro dual-cell experiments verified that spermidine activated AMPK-mediated mitophagy to directly inhibit the hyperactivation of cGAS-STING inflammatory axis, thereby restoring intestinal inflammatory homeostasis and alleviating epithelial cell injury in ulcerative colitis. Codonopsis pilosula polysaccharides extracted from the sovereign herb Codonopsis pilosula in Shenling Baizhu Formula ameliorate dextran sulfate sodium-induced ulcerative colitis, and the core mechanism depends on spermidine-triggered AMPK-mediated mitophagy to suppress the cGAS-STING inflammatory signaling axis, which plays a pivotal role in regulating intestinal immunity and repairing mucosal epithelial damage.\n --- END ACTUAL ABSTRACT FOR 42217339 ---\n\n- ERROR: You cited ID: 42331842 for the quote: \"Spermidine-induced autophagy via hypusination of eukaryotic translation initiation factor 5 A (EIF5A)\"\n FACT: Strict Misquote Detected!

While fetal lung signals are known to help initiate labor, the role of the placenta has remained unclear. Here we show that in steroid receptor coactivator (Src)-1 and -2 double-knockout mice, reduced placental amine oxidase, copper-containing 1 (Aoc1) leads to increased spermidine levels. In trophoblast cells, spermidine induces autophagy via hypusination of eukaryotic translation initiation factor 5\u2009A (EIF5A), reducing estrogen and prostaglandin production. Estrogen reciprocally increases Aoc1 expression via estrogen receptor-\u03b1 (ER\u03b1) in concert with SRC-1/2, forming a feedback loop maintaining placental autophagy homeostasis. AOC1 levels are elevated in preterm labor placentas from both mice and humans. Placenta-specific Aoc1 knockout dramatically delays labor by increasing trophoblast autophagy. Importantly, spermidine supplementation rescues inflammation-induced preterm labor in mice. Our findings reveal that placental AOC1-spermidine-EIF5A-autophagy axis is essential for parturition timing and offer a potential therapeutic strategy for preterm birth.\n --- END ACTUAL ABSTRACT FOR 42331842 ---\n\n- ERROR: You cited ID: 42343845 for the quote: \"elevated FAM134B-LC3 and calnexin-LC3 co-localization\"\n FACT: Strict Misquote Detected!

Adult SD rats were randomized into Sham operation, PSCI model, TTM, rapamycin (an autophagy inducer), 3-methyladenine (an autophagy inhibitor), and TTM+3-MA groups, and rat models of cognitive impairment were established using a modified thread occlusion method. Cognitive function of the rats was assessed using Morris water maze test. Histopathological changes, neuronal apoptosis, dendritic spines, and protein expressions of FAM134B, LC3, ATG5, P62, GRP78, Bax, Bcl-2, IL-10, IL-1\u03b2, and TNF-\u03b1 were evaluated using HE, Nissl, TUNEL, Golgi staining, immunohistochemistry, immunofluorescence staining, and Western blotting. Compared with the sham-operated rats, the rat models of PSCI showed significantly prolonged escape latency, reduced target quadrant time and platform crossings, severe hippocampal damage, increased ATG5 and GRP78 expression, elevated apoptosis, increased IL-1\u03b2, TNF-\u03b1, Bax, GRP78, and P62 expressions, and decreased IL-10, Bcl-2, and LC3 expressions, with slightly increased FAM134B-LC3 and calnexin-LC3 co-localization. Compared with those in the model group, the rats receiving TTM treatment showed significantly shortened escape latency, increased target quadrant time and platform crossings, increased ATG5 and dendritic spines, decreased GRP78 expression, enhanced FAM134B-LC3 and calnexin-LC3 co-localization, reduced IL-1\u03b2, TNF-\u03b1, Bax, GRP78, and P62 expressions, and increased FAM134B, ATG5, LC3, IL-10, and Bcl-2 expressions; the rats treated with 3-MA showed the opposite changes. Excessive ER stress is activated early after stroke, shifting from adaptive to pro-apoptotic signaling, with insufficient ER-phagy flux. TTM modulates ER-phagy, alleviates ERS, reduces neuroinflammation and apoptosis, protects dendritic spines, and improves cognitive function in rats with PSCI. \u76ee\u7684:

While fetal lung signals are known to help initiate labor, the role of the placenta has remained unclear. Here we show that in steroid receptor coactivator (Src)-1 and -2 double-knockout mice, reduced placental amine oxidase, copper-containing 1 (Aoc1) leads to increased spermidine levels. In trophoblast cells, spermidine induces autophagy via hypusination of eukaryotic translation initiation factor 5\u2009A (EIF5A), reducing estrogen and prostaglandin production. Estrogen reciprocally increases Aoc1 expression via estrogen receptor-\u03b1 (ER\u03b1) in concert with SRC-1/2, forming a feedback loop maintaining placental autophagy homeostasis. AOC1 levels are elevated in preterm labor placentas from both mice and humans. Placenta-specific Aoc1 knockout dramatically delays labor by increasing trophoblast autophagy. Importantly, spermidine supplementation rescues inflammation-induced preterm labor in mice. Our findings reveal that placental AOC1-spermidine-EIF5A-autophagy axis is essential for parturition timing and offer a potential therapeutic strategy for preterm birth.\n --- END ACTUAL ABSTRACT FOR 42331842 ---\n\n- ERROR: You cited ID: 42012729 for the quote: \"Spermidine enhances proteostasis, reduces soluble amyloid-beta, improves microglial phagocytic activity, preserves mitochondrial fitness, and attenuates inflammatory responses\"\n FACT: Strict Misquote Detected!

This review summarizes current knowledge on spermidine biology, including its synthesis, catabolism, transport, and cell-specific handling in neurons and glia, with emphasis on ATP13A2/ATP13A4-dependent trafficking and EP300-linked autophagy. Preclinical studies consistently show that spermidine enhances proteostasis, reduces soluble amyloid-beta, improves microglial phagocytic activity, preserves mitochondrial fitness, and attenuates inflammatory responses in models of aging and neurodegeneration. Human evidence is encouraging but still limited: observational studies associate higher dietary spermidine intake with better cognitive outcomes, whereas interventional trials suggest possible benefits in subjective cognitive decline and mild dementia, with variable dose-dependent effects. Overall, spermidine is a biologically plausible nutraceutical for healthy brain aging, but larger, well-designed clinical trials are needed to define efficacy, bioavailability, safety, and optimal therapeutic use across prodromal, early-stage, and disease-specific patient populations.\n --- END ACTUAL ABSTRACT FOR 42012729 ---\n\n- ERROR: You cited ID: 42346630 for the quote: \"SFN exerts photoprotective effects across multiple experimental models... consistently activated the Nrf2 pathway\"\n FACT: Ellipses (...) are strictly forbidden.

The nuclear factor erythroid 2-related factor 2 (Nrf2) pathway plays a central role in regulating cellular antioxidant defences against UV-induced damage. This scoping review aims to evaluate the potential role of sulforaphane (SFN), a known Nrf2 inducer, in protecting against UV-induced skin damage and photocarcinogenesis. Methods: A literature search was conducted in PubMed and Scopus from inception to 27 January 2026, to identify original experimental studies investigating SFN, glucoraphanin, or broccoli sprout extracts in the context of UV-induced skin damage. Eligible studies included in vitro, ex vivo, in vivo, and human models assessing outcomes related to oxidative stress, inflammation, molecular signalling pathways, and tumour development. Following screening and eligibility assessment, twelve studies were included in the qualitative synthesis. Results: The included studies suggest that SFN exerts photoprotective effects across multiple experimental models. In murine studies, SFN and SFN-rich extracts were associated with a reduction in tumour incidence, multiplicity, and volume following UV exposure. In human studies, topical SFN application reduced UV-induced erythema and induced cytoprotective enzyme expression, although clinical evidence remains limited. Mechanistically, SFN consistently activated the Nrf2 pathway, leading to increased expression of antioxidant and phase II detoxifying enzymes, and was associated with modulation of inflammatory responses and inhibition of MAPK/AP-1 signalling. Emerging evidence also indicates potential effects on UV-induced metabolic and epigenetic alterations. Conclusions: Current evidence supports a potential role for sulforaphane in mitigating UV-induced skin damage through activation of endogenous defence pathways. However, the available data are predominantly preclinical, and further well-designed clinical studies are needed to clarify its efficacy and translational relevance in humans.\n --- END ACTUAL ABSTRACT FOR 42346630 ---\n\n- ERROR: You cited ID: 41784832 for the quote: \"Crocin treatment... restored neurotransmitter balance, downregulated NMDAR, upregulated EAAT2, increased p-Akt expression level and reduced tau phosphorylation.\"\n FACT: Ellipses (...) are strictly forbidden.

Downregulation of EAAT2 results in glutamate accumulation, N-Methyl-D-Aspartate (NMDA) receptor overactivation, and neuronal injury. Crocin (Cr), a carotenoid compound extracted from saffron (Crocus sativus), exhibits potent antioxidant and neuroprotective properties, particularly in experimental models of neurodegeneration. Forty-eight adult male rats were divided into six groups: control (saline), crocin (50 mg/kg), scopolamine (3 mg/kg for 7 days), scopolamine followed by memantine (M) (20 mg/kg), scopolamine followed by crocin, and scopolamine followed by both memantine and crocin. This study aimed to evaluate the therapeutic potential of crocin, alone and in combination with memantine, in a scopolamine-induced rat model of Alzheimer's disease, with a focus on EAAT2 modulation. Scopolamine administration significantly elevated glutamate, NMDAR and p-tau levels while reducing p-Akt, GABA and EAAT2 levels, accompanied by marked hippocampal neurodegeneration. In contrast, crocin treatment, either alone or in combination with memantine, restored neurotransmitter balance, downregulated NMDAR, upregulated EAAT2, increased p-Akt expression level and reduced tau phosphorylation. Histological analysis further confirmed notable structural recovery of hippocampal neurons.\n --- END ACTUAL ABSTRACT FOR 41784832 ---\n\n- ERROR: You cited ID: 42169618 for the quote: \"Spermidine... significantly enhanced spike-specific IgG secretion, memory B cell recall responses and neutralising antibody activity, specifically in non-responders.\"\n FACT: Ellipses (...) are strictly forbidden.

Spermidine has been shown to counteract immunosenescence and induce autophagy in preclinical models, and its levels decline with age in humans. We conducted a double-blind, randomised, placebo-controlled pilot study in 40 adults over 65\u2009years of age following their third SARS-CoV-2 vaccine dose to assess the safety of Spermidine and its effects on vaccine-induced immunity. Daily oral supplementation (6\u2009mg, 13\u2009weeks) was well-tolerated. Vaccine non-responsiveness was common, and non-responders exhibited a distinct immune-senescence signature marked by elevated p16, mTOR signalling, and \u03b3-H2AX+ DNA damage in lymphocytes. Spermidine reversed these features and significantly enhanced spike-specific IgG secretion, memory B cell recall responses and neutralising antibody activity, specifically in non-responders. Single-cell RNA-seq after treatment revealed increased expression of TFEB targets and autophagy-related genes in B cells, in line with elevated autophagic flux. These findings suggest that targeting immune cell senescence with Spermidine may improve vaccine responsiveness in older adults and highlight immune-senescence markers as potential predictors of vaccine failure in ageing populations.\n --- END ACTUAL ABSTRACT FOR 42169618 ---\n\n- ERROR: You cited ID: 42092427 for the quote: \"Clostridium butyricum and its metabolite SPD... delay the cognitive decline caused by normal brain aging by reducing oxidative stress and inflammation.\"\n FACT: Ellipses (...) are strictly forbidden.

Spermidine (SPD) is known to ameliorate age-related cognitive decline, and the gut microbiota is an important source of SPD. Clostridium butyricum (C. butyricum), a probiotic, can alleviate cognitive decline in individuals with various neurodegenerative diseases, and C. butyricum might generate SPD. However, the role of C. butyricum in natural brain aging and the efficacy of C. butyricum and the metabolite SPD in ameliorating age-related cognitive decline remain unclear. Here, we investigated the effects of C. butyricum and its metabolite SPD on cognitive decline during natural brain aging and the mechanisms underlying these effects. Aged rats (aged 17 months, n\u202f=\u202f12 per group) were randomly divided into normal saline (NS), C. butyricum (1\u202f\u00d7108\u223c109 CFU/ml, by gavage for two months) and SPD (6.5\u202fmg/kg/d, by gavage for one month) groups. Compared with the NS group, the C. butyricum and SPD groups presented improved spatial reference and recognition memory, reduced aging marker levels by immunohistochemical staining, improved synaptic plasticity-related tissue structure by transmission electron microscopy and Golgi staining, and increased level of synaptophysin and BDNF by immunofluorescence staining and western blotting in the brain. Furthermore, treatment with C. butyricum and SPD enhanced intestinal barrier function and decreased serum proinflammatory factor levels and brain tissue damage due to oxidative stress. There were no significant differences in relevant indicators between the C. butyricum and SPD groups. In conclusion, C. butyricum and its metabolite SPD may delay the cognitive decline caused by normal brain aging by reducing oxidative stress and inflammation.\n --- END ACTUAL ABSTRACT FOR 42092427 ---\n\n- ERROR: You cited ID: 42346630 for the quote: \"Sulforaphane... a known Nrf2 inducer, in protecting against UV-induced skin damage\"\n FACT: Ellipses (...) are strictly forbidden.

This narrative review synthesizes preclinical and early clinical evidence on the mechanisms and therapeutic applicability of SFN in ICU-acquired weakness, diabetic myopathy, sarcopenia, and exercise-induced muscle damage. SFN modulates skeletal muscle pathophysiology through four interconnected axes: regulation of protein homeostasis via mTOR-associated signaling and suppression of ubiquitin-proteasome-mediated catabolism; upregulation of oxidative stress defenses through Nrf2-driven antioxidant enzyme induction; attenuation of inflammatory networks via NF-\u03baB inhibition and promotion of M2 macrophage polarization; and metabolic reprogramming through AMPK-mediated mitochondrial biogenesis and enhanced insulin sensitivity. Preclinical data suggest preliminary protective effects on respiratory and locomotor muscle; however, clinical translation remains uncertain. Several randomized controlled trials have failed to demonstrate significant effects on Nrf2 target genes or metabolic stress biomarkers, and bioavailability varies markedly across formulations and individuals. Heterogeneous responses across muscle fiber types, an undefined therapeutic window, and interindividual variability in gut microbiota-mediated conversion further complicate clinical application. To address these challenges, we propose a conceptual \"Sulforaphane Precision Medicine Framework\" integrating molecular biomarkers, gut microbiome profiling, and dynamic delivery systems to guide personalized intervention. While SFN shows promise as an adjunctive therapy, standardized formulations, refined patient stratification, and rigorous phase III trials are essential before routine clinical adoption can be recommended.\n --- END ACTUAL ABSTRACT FOR 42494618 ---\n\n- ERROR: You cited ID: 42468217 for the quote: \"Spermidine alleviates toxicant-induced deterioration of oocyte quality by regulating autophagy\"\n FACT: Strict Misquote Detected!

Here, we examined the effects of two haloacetamides, 2,2-dichloroacetamide (DCAcAm) and 2,2-dibromoacetamide (DBAcAm), on mouse oocyte maturation and identified the underlying mechanisms of toxicity. Both compounds markedly impaired meiotic spindle assembly and compromised the function of multiple organelles, including mitochondria, the endoplasmic reticulum, and the Golgi apparatus, primarily through autophagy dysregulation at specific exposure concentrations, as evidenced by the observation that more than half of the oocytes failed to progress beyond the MII stage. Spermidine supplementation effectively restored autophagic activity and rescued the associated cellular defects, thereby improving both nuclear and cytoplasmic maturation in oocytes. Collectively, these findings demonstrate that spermidine alleviates toxicant-induced deterioration of oocyte quality by regulating autophagy and highlight its potential therapeutic value for reproductive protection and clinical application.\n --- END ACTUAL ABSTRACT FOR 42468217 ---\n\n- ERROR: You cited ID: 42212335 for the quote: \"Spermidine supplementation improves hormonal profiles and promoted follicular development in cVKO mice.\"\n FACT: Strict Misquote Detected!

Here, we identify the vitamin D receptor (Vdr) as a key anti-aging transcription factor whose expression in granulosa cells (GCs) declines with age. Using GCs-specific Vdr knockout (cVKO) mice and a Vdr-knockout (VKO) human granulosa-like cell line, we demonstrate that loss of Vdr triggers GCs aging and disrupts ovarian function. Integrated transcriptomic and metabolomic analyses from VKO and WT cells revealed that Vdr loss downregulates the de novo spermidine (SPD) biosynthesis by directly suppressing the transcription of ornithine decarboxylase (ODC1). This led to SPD depletion, which in turn inhibited DNA methyltransferase (DNMTs) activity, resulting in hypomethylation of the p53 promoter and activation of the p53/p21 pathway. Crucially, supplementation with either SPD or its upstream methyl donor S-adenosylmethionine (SAM) rescued cVKO and VKO cell aging, improved hormonal profiles and promoted follicular development in cVKO mice. Furthermore, both supplements effectively delayed ovarian aging and improved fertility in naturally aged mice. Our study unveils the Vdr-spermidine-DNMTs axis as a fundamental mechanism safeguarding against ovarian aging, highlighting SPD and SAM as promising therapeutic agents for age-related female infertility.\n --- END ACTUAL ABSTRACT FOR 42212335 ---\n\n- ERROR: You cited ID: 41844133 for the quote: \"TUDCA alleviates ZEN-induced ER stress, restoring ER distribution and calcium homeostasis\"\n FACT: Strict Misquote Detected!

ZEN exposure induces endoplasmic reticulum (ER) stress, oxidative stress, and autophagy activation. However, the involvement of inositol-requiring enzyme 1 (IRE1)-mediated ER-phagy in ZEN-induced ER stress and embryonic competence during in vitro culture (IVC) remains unclear. Porcine embryos were cultured with 2.5, 5, and 10\u202f\u03bcM ZEN for two days after in vitro fertilization (IVF) to assess blastocyst development. ZEN exposure caused a significant dose-dependent decrease in blastocyst formation, expanded blastocysts, and total cell number (p\u202f<\u202f0.05). ZEN-treated embryos exhibited increased DNA fragmentation along with elevated mitochondrial and intracellular Ca\u00b2\u207a levels (p\u202f<\u202f0.001), as confirmed using terminal deoxynucleotidyl transferase dUTP nick-end labeling assay and Rhod-2 and Fluo-4 AM staining. ER-tracker analysis revealed decreased ER fluorescence intensity and increased uneven cytoplasmic ER distribution in blastocysts exposed to 5 and 10\u202f\u03bcM ZEN (p\u202f<\u202f0.001). Western blotting showed activation of the unfolded protein response (UPR) with increased expression of glucose-regulated protein 78 (GRP78), p-IRE1, IRE1, p-c-Jun N-terminal kinase (JNK), JNK, C/EBP homologous protein (CHOP), and the autophagy marker microtubule-associated protein 1 light chain 3 beta (LC3B) (p\u202f<\u202f0.05), whereas the ER-phagy receptor family with sequence similarity 134, member B was downregulated. Tauroursodeoxycholic acid (TUDCA) alleviated ZEN-induced ER stress, restoring ER distribution and calcium homeostasis, reducing DNA damage, and improving blastocyst development.

The identification of specific ER-phagy receptors including FAM134A, FAM134B, FAM134C, TEX264, SEC62, RTN3L, CCPG1, ATL3, CALCOCO1 and others has significantly advanced our understanding of ER quality control mechanisms. In this review we summarize the current knowledge on ER-phagy receptors, and emerging evidence linking ER-phagy dysfunction to various disease pathologies including neurological disorders, cancer, metabolic diseases, cardiovascular diseases, infections and immune disorders. Recent evidence shows that ER-phagy receptors can form novel ER-derived structures, such as ER-tubular bodies (ER-TBs) consisted of ATL3 and RTN3L, which mediate Golgi-bypassing unconventional protein secretion under stress conditions, revealing non-degradative functions of these receptors beyond quality control.

This study demonstrates that fecal microbiota transplantation (FMT) confers protection against RILI through modulation of the gut-lung axis. In a total lung irradiation (TLI) mouse model, FMT significantly alleviated pulmonary histopathological injury, inflammatory responses, oxidative stress, and collagen deposition during fibrogenesis. Concurrently, FMT improved intestinal motility, enhanced mucosal barrier integrity, and restored TLI-induced dysbiosis in gut microbiota diversity and community structure. Metabolomic analysis revealed that TLI significantly disrupted the metabolism of unsaturated fatty acids and arachidonic acid (AA), whereas FMT partially restored these metabolic networks. Transcriptomic and ultrastructural analyses indicated that RILI suppressed endoplasmic reticulum (ER) protein processing and induced ER swelling, while FMT promoted protective ER-phagy and facilitated restoration of ER morphology. Integrated multi-omics analysis further identified the AA metabolism as a key component of FMT-mediated protection, with its alterations closely associated with pulmonary tissue repair. Further in vivo and in vitro experiments demonstrated that AA binds to and activates the nuclear receptor PPAR\u03b3, leading to transcriptional upregulation of FAM134B, promoting protective ER-phagy and ameliorating RILI. In summary, this study highlights the bidirectional gut-lung axis as a therapeutic target in RILI progression and intervention, and reveals that FMT confers protection through metabolic remodeling and activation of the PPAR\u03b3-FAM134B-mediated ER-phagy pathway, providing a mechanistic basis for potential clinical translation.\n --- END ACTUAL ABSTRACT FOR 41564102 ---\n\n- ERROR: You cited ID: 42197044 for the quote: \"Dietary polyamine intake across age groups in Spain... growing evidence, particularly for SPD, suggests that polyamine-rich diets may protect against age-related conditions\"\n FACT: Ellipses (...) are strictly forbidden.

Growing evidence, particularly for SPD, suggests that polyamine-rich diets may protect against age-related conditions such as cardiovascular disease, metabolic syndrome, and neurodegenerative disorders. As endogenous polyamine synthesis declines with age, dietary intake becomes increasingly important, especially in older adults. This study estimated each polyamine (PU, SPD and SPM) and total polyamine intake in the Spanish population using food consumption data from the Spanish Ministry of Agriculture, Fisheries and Food. Intakes were evaluated across four age groups, and major dietary sources were identified. Total polyamine intake increased with age, reaching 393 \u00b5mol/day in adults over 65 years. PU accounted for 49% of total intake, followed by SPD (29%) and SPM (22%). Plant-based foods were the primary contributors to SPD intake, particularly vegetables (36%), fruits (26%), and cereals (18%). PU intake was also predominantly plant-derived, mainly from fruits (58%) and vegetables (23%), whereas SPM intake was largely associated with meat products (59%). A theoretical Mediterranean diet model yielded a slightly higher total polyamine intake of 406.6 \u00b5mol/day and a substantially greater SPD intake than that observed in older adults (193.99 \u00b5mol/day versus 121.62 \u00b5mol/day). Overall, estimated polyamine intake in the Spanish population fell below the optimal level of 540 \u00b5mol/day proposed in the literature.

This study demonstrates that fecal microbiota transplantation (FMT) confers protection against RILI through modulation of the gut-lung axis. In a total lung irradiation (TLI) mouse model, FMT significantly alleviated pulmonary histopathological injury, inflammatory responses, oxidative stress, and collagen deposition during fibrogenesis. Concurrently, FMT improved intestinal motility, enhanced mucosal barrier integrity, and restored TLI-induced dysbiosis in gut microbiota diversity and community structure. Metabolomic analysis revealed that TLI significantly disrupted the metabolism of unsaturated fatty acids and arachidonic acid (AA), whereas FMT partially restored these metabolic networks. Transcriptomic and ultrastructural analyses indicated that RILI suppressed endoplasmic reticulum (ER) protein processing and induced ER swelling, while FMT promoted protective ER-phagy and facilitated restoration of ER morphology. Integrated multi-omics analysis further identified the AA metabolism as a key component of FMT-mediated protection, with its alterations closely associated with pulmonary tissue repair. Further in vivo and in vitro experiments demonstrated that AA binds to and activates the nuclear receptor PPAR\u03b3, leading to transcriptional upregulation of FAM134B, promoting protective ER-phagy and ameliorating RILI. In summary, this study highlights the bidirectional gut-lung axis as a therapeutic target in RILI progression and intervention, and reveals that FMT confers protection through metabolic remodeling and activation of the PPAR\u03b3-FAM134B-mediated ER-phagy pathway, providing a mechanistic basis for potential clinical translation.\n --- END ACTUAL ABSTRACT FOR 41564102 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Butyrate intervention restored microbial homeostasis and enriched SCFA-producing communities.\" (Source: 42610256)\n- \"Butyrate prophylaxis was associated with lower bacterial loads in the blood and brain tissue, preserved expression of tight junction proteins (ZO-1, Claudin-5, and Occludin) in the brain, and maintained blood-brain barrier (BBB) integrity and permeability.\" (Source: 42610256)\n- \"Sulforaphane, which activates the NRF2 antioxidant pathway, restored prelimbic neuronal activity and rescued maladaptive affective behaviors in ALDH7A1 knockout mice but did not prevent seizures.\" (Source: 42525741)\n- \"Spermidine supplementation effectively restored autophagic activity and rescued the associated cellular defects, thereby improving both nuclear and cytoplasmic maturation in oocytes.\" (Source: 42468217)\n- \"FAM134B-mediated ER-phagy degrades APP and suppresses Alzheimer's disease pathology.\" (Source: 42192129)\n- \"Western blot analysis in C8-D1A astrocytic cells demonstrated increased expression of excitatory amino acid transporter 2 (EAAT2) following HCM-01 treatment compared with control and reference drug-treated groups\" (Source: 42051019)\n- \"glutamate excitotoxicity (mediated by GluN2B-NMDAR subunit shifts, Ca\u00b2\u207a overload, and astrocytic EAAT2/GLT-1 downregulation).\" (Source: 42128064)\n- \"The ERS inhibitor 4-PBA markedly attenuated Cd-induced hepatic injury.\" (Source: 42491593)\n- \"FAM134B/RETREG1 as a specific ER-phagy receptor mediating amyloid precursor protein (APP) degradation.\" (Source: 42192129)\n- \"SPD mitigates SICM by orchestrating the restoration of mitochondrial quality control, normalization of mitophagic flux, and stabilization of cellular redox homeostasis.\" (Source: 42013738)\n- \"Nano-Se notably restrained Cd-activated ER-phagy and excessive lysosomal acidification.

Here, we investigated whether the polyamine biosynthetic enzyme S-adenosylmethionine decarboxylase 1 (AMD1) regulates tubular senescence and repair outcomes after AKI and elucidated the underlying mechanism. AMD1 dynamics were examined in an ischemia-reperfusion injury model using male C57BL/6J mice by immunofluorescence. AAV-mediated Ksp promoter-driven tubule-specific Amd1 conditional knockdown male mice (Amd1 cKD) were used to assess renal injury, cell-cycle status, senescence, and remodeling, and exogenous spermidine was administered for rescue. DNA damage signaling and p53/p21 activation were evaluated by immunostaining, Western blotting, and EdU incorporation assays. AMD1 was predominantly expressed in the tubular epithelium, with prominent dynamic induction in proximal tubules early after IRI, but declined to baseline levels during the late phase, representing a relative metabolic insufficiency that correlated inversely with fibrosis. Compared with wild-type controls, Amd1 cKD mice exhibited aggravated tubular injury, an over two-fold increase in SA-\u03b2-gal-positive areas, elevated p21, and reduced Ki67+ proliferation. Conversely, spermidine supplementation improved renal function, reduced fibrosis by 75.3%, and decreased senescent regions by 74%. Mechanistically, AMD1 deficiency increased \u03b3H2AX-marked DNA damage and activated the p53/p21 checkpoint, whereas spermidine attenuated this response and restored DNA synthesis capacity. Collectively, tubular AMD1 acts as a metabolic checkpoint that preserves polyamine homeostasis to restrain p53/p21-dependent senescence, promote adaptive repair after AKI, and spermidine supplementation represents a potential strategy to mitigate maladaptive AKI-to-CKD progression.\n --- END ACTUAL ABSTRACT FOR 42289383 ---\n\n- ERROR: You cited ID: 42331842 for the quote: \"Spermidine supplementation rescues inflammation-induced preterm labor in mice.\"\n FACT: Strict Misquote Detected!

While fetal lung signals are known to help initiate labor, the role of the placenta has remained unclear. Here we show that in steroid receptor coactivator (Src)-1 and -2 double-knockout mice, reduced placental amine oxidase, copper-containing 1 (Aoc1) leads to increased spermidine levels. In trophoblast cells, spermidine induces autophagy via hypusination of eukaryotic translation initiation factor 5\u2009A (EIF5A), reducing estrogen and prostaglandin production. Estrogen reciprocally increases Aoc1 expression via estrogen receptor-\u03b1 (ER\u03b1) in concert with SRC-1/2, forming a feedback loop maintaining placental autophagy homeostasis. AOC1 levels are elevated in preterm labor placentas from both mice and humans. Placenta-specific Aoc1 knockout dramatically delays labor by increasing trophoblast autophagy. Importantly, spermidine supplementation rescues inflammation-induced preterm labor in mice. Our findings reveal that placental AOC1-spermidine-EIF5A-autophagy axis is essential for parturition timing and offer a potential therapeutic strategy for preterm birth.\n --- END ACTUAL ABSTRACT FOR 42331842 ---\n\n- ERROR: You cited ID: 41784832 for the quote: \"Crocin treatment, either alone or in combination with memantine, restored neurotransmitter balance, downregulated NMDAR, upregulated EAAT2, increased p-Akt expression level and reduced tau phosphorylation.\"\n FACT: Strict Misquote Detected!

Downregulation of EAAT2 results in glutamate accumulation, N-Methyl-D-Aspartate (NMDA) receptor overactivation, and neuronal injury. Crocin (Cr), a carotenoid compound extracted from saffron (Crocus sativus), exhibits potent antioxidant and neuroprotective properties, particularly in experimental models of neurodegeneration. Forty-eight adult male rats were divided into six groups: control (saline), crocin (50 mg/kg), scopolamine (3 mg/kg for 7 days), scopolamine followed by memantine (M) (20 mg/kg), scopolamine followed by crocin, and scopolamine followed by both memantine and crocin. This study aimed to evaluate the therapeutic potential of crocin, alone and in combination with memantine, in a scopolamine-induced rat model of Alzheimer's disease, with a focus on EAAT2 modulation. Scopolamine administration significantly elevated glutamate, NMDAR and p-tau levels while reducing p-Akt, GABA and EAAT2 levels, accompanied by marked hippocampal neurodegeneration. In contrast, crocin treatment, either alone or in combination with memantine, restored neurotransmitter balance, downregulated NMDAR, upregulated EAAT2, increased p-Akt expression level and reduced tau phosphorylation. Histological analysis further confirmed notable structural recovery of hippocampal neurons.\n --- END ACTUAL ABSTRACT FOR 41784832 ---\n\n- ERROR: You cited ID: 42092427 for the quote: \"Clostridium butyricum and its metabolite SPD may delay the cognitive decline caused by natural brain aging by reducing oxidative stress and inflammation.\"\n FACT: Strict Misquote Detected!

Spermidine (SPD) is known to ameliorate age-related cognitive decline, and the gut microbiota is an important source of SPD. Clostridium butyricum (C. butyricum), a probiotic, can alleviate cognitive decline in individuals with various neurodegenerative diseases, and C. butyricum might generate SPD. However, the role of C. butyricum in natural brain aging and the efficacy of C. butyricum and the metabolite SPD in ameliorating age-related cognitive decline remain unclear. Here, we investigated the effects of C. butyricum and its metabolite SPD on cognitive decline during natural brain aging and the mechanisms underlying these effects. Aged rats (aged 17 months, n\u202f=\u202f12 per group) were randomly divided into normal saline (NS), C. butyricum (1\u202f\u00d7108\u223c109 CFU/ml, by gavage for two months) and SPD (6.5\u202fmg/kg/d, by gavage for one month) groups. Compared with the NS group, the C. butyricum and SPD groups presented improved spatial reference and recognition memory, reduced aging marker levels by immunohistochemical staining, improved synaptic plasticity-related tissue structure by transmission electron microscopy and Golgi staining, and increased level of synaptophysin and BDNF by immunofluorescence staining and western blotting in the brain. Furthermore, treatment with C. butyricum and SPD enhanced intestinal barrier function and decreased serum proinflammatory factor levels and brain tissue damage due to oxidative stress. There were no significant differences in relevant indicators between the C. butyricum and SPD groups. In conclusion, C. butyricum and its metabolite SPD may delay the cognitive decline caused by normal brain aging by reducing oxidative stress and inflammation.\n --- END ACTUAL ABSTRACT FOR 42092427 ---\n\n- ERROR: You cited ID: 42346630 for the quote: \"Sulforaphane, a known Nrf2 inducer, in protecting against UV-induced skin damage\"\n FACT: Strict Misquote Detected!

The nuclear factor erythroid 2-related factor 2 (Nrf2) pathway plays a central role in regulating cellular antioxidant defences against UV-induced damage. This scoping review aims to evaluate the potential role of sulforaphane (SFN), a known Nrf2 inducer, in protecting against UV-induced skin damage and photocarcinogenesis. Methods: A literature search was conducted in PubMed and Scopus from inception to 27 January 2026, to identify original experimental studies investigating SFN, glucoraphanin, or broccoli sprout extracts in the context of UV-induced skin damage. Eligible studies included in vitro, ex vivo, in vivo, and human models assessing outcomes related to oxidative stress, inflammation, molecular signalling pathways, and tumour development. Following screening and eligibility assessment, twelve studies were included in the qualitative synthesis. Results: The included studies suggest that SFN exerts photoprotective effects across multiple experimental models. In murine studies, SFN and SFN-rich extracts were associated with a reduction in tumour incidence, multiplicity, and volume following UV exposure. In human studies, topical SFN application reduced UV-induced erythema and induced cytoprotective enzyme expression, although clinical evidence remains limited. Mechanistically, SFN consistently activated the Nrf2 pathway, leading to increased expression of antioxidant and phase II detoxifying enzymes, and was associated with modulation of inflammatory responses and inhibition of MAPK/AP-1 signalling. Emerging evidence also indicates potential effects on UV-induced metabolic and epigenetic alterations. Conclusions: Current evidence supports a potential role for sulforaphane in mitigating UV-induced skin damage through activation of endogenous defence pathways. However, the available data are predominantly preclinical, and further well-designed clinical studies are needed to clarify its efficacy and translational relevance in humans.\n --- END ACTUAL ABSTRACT FOR 42346630 ---\n\n- ERROR: You cited ID: 42494618 for the quote: \"Sulforaphane, a bioactive isothiocyanate abundant in cruciferous vegetables, has attracted growing interest as a potential nutraceutical intervention for skeletal muscle disorders.\"\n FACT: Strict Misquote Detected!

This narrative review synthesizes preclinical and early clinical evidence on the mechanisms and therapeutic applicability of SFN in ICU-acquired weakness, diabetic myopathy, sarcopenia, and exercise-induced muscle damage. SFN modulates skeletal muscle pathophysiology through four interconnected axes: regulation of protein homeostasis via mTOR-associated signaling and suppression of ubiquitin-proteasome-mediated catabolism; upregulation of oxidative stress defenses through Nrf2-driven antioxidant enzyme induction; attenuation of inflammatory networks via NF-\u03baB inhibition and promotion of M2 macrophage polarization; and metabolic reprogramming through AMPK-mediated mitochondrial biogenesis and enhanced insulin sensitivity. Preclinical data suggest preliminary protective effects on respiratory and locomotor muscle; however, clinical translation remains uncertain. Several randomized controlled trials have failed to demonstrate significant effects on Nrf2 target genes or metabolic stress biomarkers, and bioavailability varies markedly across formulations and individuals. Heterogeneous responses across muscle fiber types, an undefined therapeutic window, and interindividual variability in gut microbiota-mediated conversion further complicate clinical application. To address these challenges, we propose a conceptual \"Sulforaphane Precision Medicine Framework\" integrating molecular biomarkers, gut microbiome profiling, and dynamic delivery systems to guide personalized intervention. While SFN shows promise as an adjunctive therapy, standardized formulations, refined patient stratification, and rigorous phase III trials are essential before routine clinical adoption can be recommended.\n --- END ACTUAL ABSTRACT FOR 42494618 ---\n\n- ERROR: You cited ID: 42468217 for the quote: \"Spermidine alleviates toxicant-induced deterioration of oocyte quality by regulating autophagy\"\n FACT: Strict Misquote Detected!

Here, we examined the effects of two haloacetamides, 2,2-dichloroacetamide (DCAcAm) and 2,2-dibromoacetamide (DBAcAm), on mouse oocyte maturation and identified the underlying mechanisms of toxicity. Both compounds markedly impaired meiotic spindle assembly and compromised the function of multiple organelles, including mitochondria, the endoplasmic reticulum, and the Golgi apparatus, primarily through autophagy dysregulation at specific exposure concentrations, as evidenced by the observation that more than half of the oocytes failed to progress beyond the MII stage. Spermidine supplementation effectively restored autophagic activity and rescued the associated cellular defects, thereby improving both nuclear and cytoplasmic maturation in oocytes. Collectively, these findings demonstrate that spermidine alleviates toxicant-induced deterioration of oocyte quality by regulating autophagy and highlight its potential therapeutic value for reproductive protection and clinical application.\n --- END ACTUAL ABSTRACT FOR 42468217 ---\n\n- ERROR: You cited ID: 42012729 for the quote: \"Spermidine enhances proteostasis, reduces soluble amyloid-beta, improves microglial phagocytic activity, preserves mitochondrial fitness, and attenuates inflammatory responses\"\n FACT: Strict Misquote Detected!

This review summarizes current knowledge on spermidine biology, including its synthesis, catabolism, transport, and cell-specific handling in neurons and glia, with emphasis on ATP13A2/ATP13A4-dependent trafficking and EP300-linked autophagy. Preclinical studies consistently show that spermidine enhances proteostasis, reduces soluble amyloid-beta, improves microglial phagocytic activity, preserves mitochondrial fitness, and attenuates inflammatory responses in models of aging and neurodegeneration. Human evidence is encouraging but still limited: observational studies associate higher dietary spermidine intake with better cognitive outcomes, whereas interventional trials suggest possible benefits in subjective cognitive decline and mild dementia, with variable dose-dependent effects. Overall, spermidine is a biologically plausible nutraceutical for healthy brain aging, but larger, well-designed clinical trials are needed to define efficacy, bioavailability, safety, and optimal therapeutic use across prodromal, early-stage, and disease-specific patient populations.\n --- END ACTUAL ABSTRACT FOR 42012729 ---\n\n- ERROR: You cited ID: 42331842 for the quote: \"Spermidine induces autophagy via hypusination of eukaryotic translation initiation factor 5 A (EIF5A), reducing estrogen and prostaglandin production.\"\n FACT: Strict Misquote Detected!

AMD1 dynamics were examined in an ischemia-reperfusion injury model using male C57BL/6J mice by immunofluorescence. AAV-mediated Ksp promoter-driven tubule-specific Amd1 conditional knockdown male mice (Amd1 cKD) were used to assess renal injury, cell-cycle status, senescence, and remodeling, and exogenous spermidine was administered for rescue. DNA damage signaling and p53/p21 activation were evaluated by immunostaining, Western blotting, and EdU incorporation assays. AMD1 was predominantly expressed in the tubular epithelium, with prominent dynamic induction in proximal tubules early after IRI, but declined to baseline levels during the late phase, representing a relative metabolic insufficiency that correlated inversely with fibrosis. Compared with wild-type controls, Amd1 cKD mice exhibited aggravated tubular injury, an over two-fold increase in SA-\u03b2-gal-positive areas, elevated p21, and reduced Ki67+ proliferation. Conversely, spermidine supplementation improved renal function, reduced fibrosis by 75.3%, and decreased senescent regions by 74%. Mechanistically, AMD1 deficiency increased \u03b3H2AX-marked DNA damage and activated the p53/p21 checkpoint, whereas spermidine attenuated this response and restored DNA synthesis capacity. Collectively, tubular AMD1 acts as a metabolic checkpoint that preserves polyamine homeostasis to restrain p53/p21-dependent senescence, promote adaptive repair after AKI, and spermidine supplementation represents a potential strategy to mitigate maladaptive AKI-to-CKD progression.\n --- END ACTUAL ABSTRACT FOR 42289383 ---\n\n- ERROR: You cited ID: 42343845 for the quote: \"excessive ER stress is activated early after stroke, shifting from adaptive to pro-apoptotic signaling, with insufficient ER-phagy flux.\"\n FACT: Strict Misquote Detected!

Histopathological changes, neuronal apoptosis, dendritic spines, and protein expressions of FAM134B, LC3, ATG5, P62, GRP78, Bax, Bcl-2, IL-10, IL-1\u03b2, and TNF-\u03b1 were evaluated using HE, Nissl, TUNEL, Golgi staining, immunohistochemistry, immunofluorescence staining, and Western blotting. Compared with the sham-operated rats, the rat models of PSCI showed significantly prolonged escape latency, reduced target quadrant time and platform crossings, severe hippocampal damage, increased ATG5 and GRP78 expression, elevated apoptosis, increased IL-1\u03b2, TNF-\u03b1, Bax, GRP78, and P62 expressions, and decreased IL-10, Bcl-2, and LC3 expressions, with slightly increased FAM134B-LC3 and calnexin-LC3 co-localization. Compared with those in the model group, the rats receiving TTM treatment showed significantly shortened escape latency, increased target quadrant time and platform crossings, increased ATG5 and dendritic spines, decreased GRP78 expression, enhanced FAM134B-LC3 and calnexin-LC3 co-localization, reduced IL-1\u03b2, TNF-\u03b1, Bax, GRP78, and P62 expressions, and increased FAM134B, ATG5, LC3, IL-10, and Bcl-2 expressions; the rats treated with 3-MA showed the opposite changes. Excessive ER stress is activated early after stroke, shifting from adaptive to pro-apoptotic signaling, with insufficient ER-phagy flux. TTM modulates ER-phagy, alleviates ERS, reduces neuroinflammation and apoptosis, protects dendritic spines, and improves cognitive function in rats with PSCI. \u76ee\u7684:

ZEN exposure induces endoplasmic reticulum (ER) stress, oxidative stress, and autophagy activation. However, the involvement of inositol-requiring enzyme 1 (IRE1)-mediated ER-phagy in ZEN-induced ER stress and embryonic competence during in vitro culture (IVC) remains unclear. Porcine embryos were cultured with 2.5, 5, and 10\u202f\u03bcM ZEN for two days after in vitro fertilization (IVF) to assess blastocyst development. ZEN exposure caused a significant dose-dependent decrease in blastocyst formation, expanded blastocysts, and total cell number (p\u202f<\u202f0.05). ZEN-treated embryos exhibited increased DNA fragmentation along with elevated mitochondrial and intracellular Ca\u00b2\u207a levels (p\u202f<\u202f0.001), as confirmed using terminal deoxynucleotidyl transferase dUTP nick-end labeling assay and Rhod-2 and Fluo-4 AM staining. ER-tracker analysis revealed decreased ER fluorescence intensity and increased uneven cytoplasmic ER distribution in blastocysts exposed to 5 and 10\u202f\u03bcM ZEN (p\u202f<\u202f0.001). Western blotting showed activation of the unfolded protein response (UPR) with increased expression of glucose-regulated protein 78 (GRP78), p-IRE1, IRE1, p-c-Jun N-terminal kinase (JNK), JNK, C/EBP homologous protein (CHOP), and the autophagy marker microtubule-associated protein 1 light chain 3 beta (LC3B) (p\u202f<\u202f0.05), whereas the ER-phagy receptor family with sequence similarity 134, member B was downregulated. Tauroursodeoxycholic acid (TUDCA) alleviated ZEN-induced ER stress, restoring ER distribution and calcium homeostasis, reducing DNA damage, and improving blastocyst development. These findings suggest that ZEN disrupts IRE1 signaling and suppresses ER-phagy during early porcine embryo development, whereas TUDCA alleviates ER stress and improves embryonic competence during IVC.\n --- END ACTUAL ABSTRACT FOR 41844133 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Butyrate intervention restored microbial homeostasis and enriched SCFA-producing communities.\" (Source:

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]\n\"Dietary butyrate from resistant starch may synergize with sulforaphane-driven Nrf2 activation and spermidine-mediated FAM134B ER-phagy in order to restore astrocytic EAAT2 membrane trafficking and potentially clear synaptic glutamate excitotoxicity in neurodegeneration.\"\n\nBased on the provided literature, this hypothesis is mechanistically plausible. The evidence indicates that (1) dietary resistant starch increases butyrate production; (2) butyrate, sulforaphane, and spermidine independently activate Nrf2 and antioxidant defenses; (3) FAM134B-mediated ER-phagy is a mechanism for maintaining ER and cellular homeostasis; and (4) restoring astrocytic EAAT2 function is a critical strategy for mitigating glutamate excitotoxicity. While no single study describes this precise tripartite synergy, the individual components and pathways are well-documented as overlapping regulators of neuronal and glial survival in neurodegenerative models.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThis assessment synthesizes evidence regarding the modulation of redox homeostasis (via Nrf2), protein quality control (via ER-phagy), and glutamate uptake (via EAAT2). The proposed synergy between dietary butyrate, sulforaphane, and spermidine offers a novel, multi-target approach to neuroprotection by converging on these shared homeostatic nodes.\n\n### [INTRODUCTION & JUSTIFICATION]\nNeurodegenerative processes such as Alzheimer\u2019s and Parkinson\u2019s diseases are driven by convergent pathologies: oxidative stress, neuroinflammation, and glutamate excitotoxicity. Astrocytic EAAT2, the primary glutamate transporter, is frequently downregulated in these conditions, leading to synaptic glutamate accumulation and subsequent neuronal death. The literature demonstrates that dietary fiber/resistant starch promotes the production of SCFAs like butyrate, which serves as a major energy source for colonocytes and supports gut-brain axis homeostasis. Mechanistically, butyrate regulates Nrf2 and antioxidant pathways. Sulforaphane functions as a potent Nrf2 inducer, while spermidine enhances autophagic flux\u2014specifically FAM134B-mediated ER-phagy. Given that EAAT2 expression and membrane trafficking are susceptible to oxidative and ER stress, the combination of these agents potentially stabilizes the astrocytic proteome and redox environment, thereby preventing the collapse of glutamate buffering.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Butyrate and resistant starch are not merely metabolic fuels but active modulators of the gut-brain axis, impacting both Nrf2 signaling and microbiota composition.\n* FAM134B-mediated ER-phagy is emerging as a critical nexus for both viral restriction and cellular quality control in AD, with its downregulation serving as an early pathogenic event.\n* Spermidine does not only induce autophagy but also impacts hypusination of EIF5A, a process essential for regulating placental and potentially astrocytic protein synthesis.\n* Sulforaphane shows consistent photoprotective and neuroprotective effects, but its clinical utility remains constrained by variability in gut microbiome-mediated conversion.\n* T-2 toxin and cadmium toxicity share a common mechanism of suppressing FAM134B-mediated ER-phagy, linking environmental pollution to homeostatic decline.\n* Spermidine and sulforaphane independently stabilize mitochondrial and ER function, providing a combined metabolic and proteostatic shield for glial cells.\n* The cGAS-STING inflammatory axis is directly repressed by spermidine-mediated mitophagy, highlighting an immunological dimension to its neuroprotective profile.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

"41413198": "ID: 41413198\nTitle: Inhibition of STING-mediated antiviral innate immunity activation by CD97 via modulation of ER-phagy.\nAbstract: Endoplasmic reticulum (ER) autophagy (ER-phagy) is a vital homeostatic process triggered by multiple signals and plays a crucial role in regulating innate immunity and viral replication. However, the mechanisms by which host proteins utilize ER-phagy to regulate innate immune response during viral infection remains largely unclear. Here, we uncover the regulatory crosstalk between innate immune adapter, ER retention protein Stimulator of Interferon Genes (STING), and the G protein-coupled receptor ADGRE5/CD97 (Cluster of Differentiation 97). Our results demonstrate that CD97 suppresses the STING-mediated type-I interferon (IFN-I) response against DNA virus and cytosolic DNA, thereby promoting herpes simplex virus type 1 (HSV-1) replication in both cells and mice. CD97 facilitates the recruitment of the ER-phagy receptor, FAM134B (family with sequence similarity 134, member B), to initiate ER-phagy, resulting in the degradation of STING subsequent to DNA virus infection. Furthermore, Cd97-deficient mice exhibit higher IFN-I response and greater resistance to HSV-1 infection. Additionally, our findings reveal that inhibiting CD97 with sanguinarine effectively disrupts HSV-1 replication. These findings shed light on the role of CD97 in the innate immune response against DNA virus infections and offer valuable checkpoint for anti-viral STING activation.",
"41438769": "ID: 41438769\nTitle: RETREG1/FAM134B-mediated micro-ER-phagy in the retrovirus-SERINC5 arms race.\nAbstract: Reticulophagy regulator 1 (RETREG1)/Family with sequence similarity 134 member B (FAM134B) is a selective endoplasmic reticulum (ER)-phagy receptor that mediates starvation-induced macro-ER-phagy, but whether it participates in other pathways mediating ER turnover has remained unclear. Here, we unveil a previously unrecognized role for RETREG1 in micro-ER-phagy and show how the murine leukemia virus (MLV) accessory protein glycosylated group-specific antigen (glycoGag) exploits this pathway to antagonize the host restriction factor SERINC5 (serine incorporator 5). GlycoGag binds SERINC5 in the endoplasmic reticulum (ER) and selectively recruits RETREG1 to eliminate SERINC5 through an autophagosome-independent process that bypasses ATG3 (autophagy-related), ATG5, ATG7, BECN1 (Beclin-1), LC3 (microtubule-associated protein 1 light chain 3) lipidation, and PIK3C3 (phosphatidylinositol 3-kinase catalytic subunit type 3)/hVPS34 (vacuolar protein sorting 34). RETREG1 knockout abolishes degradation of ER-retained SERINC5, whereas endolysosomal turnover of surface SERINC5 remains partially intact, demonstrating that glycoGag utilizes dual ER-phagy and endolysosomal routes to suppress SERINC5. These findings expand the functional repertoire of RETREG1 in autophagy, identify that retroviruses repurpose micro-ER-phagy to circumvent SERINC5-mediated restriction, and reveal ER-phagy as an understudied battleground in the ongoing arms race between cellular restriction factors and viral accessory proteins.",
"41462664": "ID: 41462664\nTitle: Chronic Stress and Astrocyte Dysfunction in Depression: Molecular Mechanisms and Gene Expression Changes.\nAbstract: Major depressive disorder (MDD) is a complex and heterogeneous psychiatric condition with high global prevalence and significant personal and societal burdens. While traditionally focused on neuronal dysfunction, emerging research highlights a critical role for astrocytes-glial cells essential for maintaining brain homeostasis in the pathogenesis of depression. This review explores how chronic stress, a major risk factor for MDD, disrupts astrocyte function through multiple converging mechanisms. We detail the normal physiological roles of astrocytes in synaptic regulation, neurotransmitter cycling, metabolic support, and neurovascular integrity, and examine how these functions are compromised under chronic stress. Key molecular pathways implicated include glucocorticoid receptor (GR) signaling dysregulation, neuroinflammatory responses, glutamate excitotoxicity, oxidative stress, and epigenetic alterations. Evidence from histological and transcriptomic studies in both human postmortem tissue and rodent models reveals consistent changes in astrocyte-specific genes, such as GFAP, SLC1A2, SLC1A3, BDNF, and AQP4, supporting their involvement in depressive pathology. Finally, we discuss therapeutic strategies targeting astrocyte dysfunction-including EAAT2 upregulation, neuromodulation, anti-inflammatory approaches, GR modulation, and glial-focused epigenetic therapies. Understanding astrocyte pathology in the context of chronic stress not only refines our understanding of MDD but also opens novel avenues for treatment development.",
"41564102": "ID: 41564102\nTitle: Fecal microbiota transplantation ameliorates radiation-induced lung injury by reshaping gut metabolic homeostasis to activate FAM134B-mediated ER-phagy.\nAbstract: Radiation-induced lung injury (RILI) is a serious complication of thoracic radiotherapy, with limited effective treatment options. This study demonstrates that fecal microbiota transplantation (FMT) confers protection against RILI through modulation of the gut-lung axis. In a total lung irradiation (TLI) mouse model, FMT significantly alleviated pulmonary histopathological injury, inflammatory responses, oxidative stress, and collagen deposition during fibrogenesis. Concurrently, FMT improved intestinal motility, enhanced mucosal barrier integrity, and restored TLI-induced dysbiosis in gut microbiota diversity and community structure. Metabolomic analysis revealed that TLI significantly disrupted the metabolism of unsaturated fatty acids and arachidonic acid (AA), whereas FMT partially restored these metabolic networks. Transcriptomic and ultrastructural analyses indicated that RILI suppressed endoplasmic reticulum (ER) protein processing and induced ER swelling, while FMT promoted protective ER-phagy and facilitated restoration of ER morphology. Integrated multi-omics analysis further identified the AA metabolism as a key component of FMT-mediated protection, with its alterations closely associated with pulmonary tissue repair. Further in vivo and in vitro experiments demonstrated that AA binds to and activates the nuclear receptor PPAR\u03b3, leading to transcriptional upregulation of FAM134B, promoting protective ER-phagy and ameliorating RILI. In summary, this study highlights the bidirectional gut-lung axis as a therapeutic target in RILI progression and intervention, and reveals that FMT confers protection through metabolic remodeling and activation of the PPAR\u03b3-FAM134B-mediated ER-phagy pathway, providing a mechanistic basis for potential clinical translation.",
"41593210": "ID: 41593210\nTitle: ER-phagy receptors: structural mechanisms in selective ER degradation and disease implications.\nAbstract: The endoplasmic reticulum (ER) is a central organelle for protein synthesis and folding, lipid metabolism and calcium signaling, etc. To maintain ER homeostasis, cells employ a specific autophagy process termed ER-phagy (reticulophagy), which depredates ER components via three forms: macro-ER-phagy (involving bulk ER sequestration), micro-ER-phagy (lysosome-direct), and ER-to-lysosome-associated degradation (ERLAD). The identification of specific ER-phagy receptors including FAM134A, FAM134B, FAM134C, TEX264, SEC62, RTN3L, CCPG1, ATL3, CALCOCO1 and others has significantly advanced our understanding of ER quality control mechanisms. In this review we summarize the current knowledge on ER-phagy receptors, and emerging evidence linking ER-phagy dysfunction to various disease pathologies including neurological disorders, cancer, metabolic diseases, cardiovascular diseases, infections and immune disorders. Recent evidence shows that ER-phagy receptors can form novel ER-derived structures, such as ER-tubular bodies (ER-TBs) consisted of ATL3 and RTN3L, which mediate Golgi-bypassing unconventional protein secretion under stress conditions, revealing non-degradative functions of these receptors beyond quality control. Targeting ER-phagy receptors may provide insights into potential therapeutic strategies for diseases associated with this fundamental cellular process.",
"41612464": "ID: 41612464\nTitle: SS-31 improves the quality of maternally aged oocytes by ameliorating mitochondrial function and metabolism.\nAbstract: Reproductive aging is closely associated with poor oocyte quality in vitro maturation, but effective approaches to ameliorate it have still not been fully determined. Here, we found that SS-31 supplementation efficaciously improved oocyte maturation and early embryonic development from aged mice. Specifically, SS-31 remarkably restored the normal spindle/chromosome structure, fertilization ability, mitochondrial distribution, \u0394\u03a8m and mitophagy in aged oocytes. In contrast, SS-31 reduced oocyte aneuploidy, ROS accumulation and DNA damage. Mechanistically, single-cell transcriptome analysis reveals that SS-31 increased the maternal mRNA degradation, and the levels of genes associated with mitochondrial function and mitophagy in aged oocytes, such as Pink1, Rps27a, Tomm7 and Map1lc3b. In addition, SS-31 suppressed chromatin organization, histone modification and chromatin remodeling pathways. Moreover, we applied the single-cell untargeted metabolomics to identify that SS-31 increased the levels of spermidine and GSH, which were critical metabolites to protect oocytes against aging. Our data reveal that the beneficial effect of SS-31 on oocyte quality from advanced age is mainly mediated by restoration of mitochondrial function, mitophagy and anti-aging metabolites. It provides a potential strategy for improving oocyte quality to extend the reproductive lifespan of female animals.",
"41617890": "ID: 41617890\nTitle: Polyamine metabolism as a regulator of cellular and organismal aging.\nAbstract: Polyamines - putrescine, spermidine, and spermine - are ubiquitous cationic molecules that are essential for cellular proliferation and homeostasis. Their intracellular concentrations decline with age, contributing to physiological and cognitive deterioration. Recent studies have revealed that spermidine supplementation extends lifespan and improves cognitive and cardiac function in various model organisms, suggesting that maintaining polyamine balance has anti-aging potential. Polyamine metabolism is tightly regulated through biosynthesis, degradation, and transport; however, age-associated upregulation of spermine oxidase (SMOX) and accumulation of its toxic byproduct acrolein promote oxidative damage and cellular senescence. Suppressing SMOX activity or polyamine degradation attenuates senescence markers and DNA damage, highlighting spermine catabolism as a therapeutic target. Polyamines also modulate epigenetic regulation, including DNA methylation and histone acetylation, thereby influencing gene expression and chromatin structure during aging. Moreover, polyamine-dependent hypusination of eIF5A sustains protein synthesis in senescent cells. These multifaceted actions indicate that polyamine metabolism integrates redox control, translational regulation, epigenetic maintenance and autophagy to determine cellular and organismal longevity. While animal studies demonstrate clear anti-aging effects of spermidine and spermine, human clinical evidence remains limited, with variable outcomes likely due to bioavailability and metabolic conversion. Future strategies combining dietary or probiotic polyamine enhancement, enzyme-targeted inhibitors, and personalized metabolic interventions hold promise for extending healthspan. Collectively, maintaining optimal polyamine homeostasis emerges as a key approach to counteract aging and age-related diseases.",
"41661358": "ID: 41661358\nTitle: MARCH6 Confers Protection Against Endoplasmic Reticulum Autophagy in Gliomas by Destabilizing FAM134B.\nAbstract: This study probed the mechanism of MARCH6 in endoplasmic reticulum autophagy (ER-phagy) during glioma development by regulating FAM134B stability. MARCH6 and FAM134B expression levels were measured in glioma tissues. A comparative analysis was conducted on the correlation between clinical parameters and FAM134B expression in 46 glioma patients. FAM134B and MARCH6 were knocked down in glioma cells, followed by detection of cell viability and apoptosis, typical ER stress (ERS) markers (PERK, IRE1\u03b1, eIF2\u03b1, and CHOP), autophagy-related proteins (P62 and LC3B), and autophagosome cytoplasmic accumulation. A mouse glioma model was established for in vivo validation. MARCH6-FAM134B interaction, FAM134B ubiquitination levels, and protein stability were examined. FAM134B expression was high and MARCH6 expression was low in glioma tissues. MARCH6 induced FAM134B protein ubiquitination and degradation, reducing its stability in glioma cells. Knockdown of FAM134B reduced glioma cell survival, inhibited PERK, IRE1\u03b1, eIF2\u03b1, and CHOP expression, decreased LC3I to LC3II conversion, lowered LC3B fluorescence expression, and reduced the accumulation of autophagosomes with continuous ER structures in the cytoplasm, while enhancing apoptosis and P62 expression. This effect can be reversed by knocking down MARCH6. In vivo, FAM134B knockdown suppressed tumorigenesis in mice. MARCH6 exerts a repressive effect on ERS responses and ER-phagy in glioma cells by destabilizing FAM134B.",
"41754095": "ID: 41754095\nTitle: The Diet-Microbiota-Polyamine Axis in Intestinal Aging: Microbial Pathways, Functional Foods, and Physiological Implications.\nAbstract: Intestinal aging is characterized by a gradual decline in epithelial renewal capacity, barrier function, immune balance, and metabolic regulation, often accompanied by shifts in gut microbial composition. Polyamines, including putrescine, spermidine, and spermine, are vital microbial-host metabolites that support intestinal cell growth, autophagy, immune modulation, and mucosal repair. With advancing age, both host-derived and microbiota-mediated polyamine production declines, contributing to intestinal dysfunction and heightened vulnerability to inflammation and age-related disorders. This review explores the diet-microbiota-polyamine axis as a key biological framework influencing intestinal aging. It aims to integrate evidence on how dietary components and functional foods shape gut microbial ecology and, in turn, regulate microbial polyamine biosynthetic pathways that impact intestinal health. The review highlights major microbial contributors to polyamine metabolism, particularly lactic acid bacteria, and outlines mechanistic pathways linking polyamines to epithelial regeneration, inflammatory control, and gut barrier maintenance. It further discusses how age-associated dysbiosis disrupts these interactions and evaluates nutritional and microbial-based strategies such as fermented foods, prebiotics, and probiotics that may enhance polyamine availability and restore gut homeostasis. From the standpoint of food microbiology and human physiology, this synthesis underscores the translational potential of targeting microbial polyamine production through diet-based interventions. This article presents a narrative review synthesizing experimental, animal, and emerging human evidence on microbial and dietary polyamines in intestinal aging. In conclusion, modulating the diet-microbiota-polyamine axis represents a promising strategy to promote healthy intestinal aging, meriting deeper mechanistic exploration and validation through clinical studies.",
"41784832": "ID: 41784832\nTitle: Crocin Mitigates Glutamate Excitotoxicity and Tau Hyperphosphorylation by Modulating EAAT2 and Akt/Tau Pathway in a Scopolamine-induced Rat Model of Alzheimer's Disease.\nAbstract: Alzheimer's disease (AD) is characterized by glutamatergic dysregulation and excitotoxicity, largely associated with impaired activity of the excitatory amino acid transporter 2 (EAAT2). Downregulation of EAAT2 results in glutamate accumulation, N-Methyl-D-Aspartate (NMDA) receptor overactivation, and neuronal injury. Crocin (Cr), a carotenoid compound extracted from saffron (Crocus sativus), exhibits potent antioxidant and neuroprotective properties, particularly in experimental models of neurodegeneration. Forty-eight adult male rats were divided into six groups: control (saline), crocin (50\u00a0mg/kg), scopolamine (3\u00a0mg/kg for 7 days), scopolamine followed by memantine (M) (20\u00a0mg/kg), scopolamine followed by crocin, and scopolamine followed by both memantine and crocin. This study aimed to evaluate the therapeutic potential of crocin, alone and in combination with memantine, in a scopolamine-induced rat model of Alzheimer's disease, with a focus on EAAT2 modulation. Scopolamine administration significantly elevated glutamate, NMDAR and p-tau levels while reducing p-Akt, GABA and EAAT2 levels, accompanied by marked hippocampal neurodegeneration. In contrast, crocin treatment, either alone or in combination with memantine, restored neurotransmitter balance, downregulated NMDAR, upregulated EAAT2, increased p-Akt expression level and reduced tau phosphorylation. Histological analysis further confirmed notable structural recovery of hippocampal neurons.",
"41797117": "ID: 41797117\nTitle: T-2 toxin induces ER stress-dependent liver injury via mitophagy-mediated ER-phagy suppression: Berbamine blocks SNARE complex for hepatoprotection.\nAbstract: T-2 toxin is a persistent, bioaccumulative environmental contaminant that poses major health threats to humans and animals. Endoplasmic reticulum (ER) stress and autophagy are two interconnected stress responses critical for maintaining cellular homeostasis. Berbamine (BBM) is an important member of bis-benzy lisoquinoline alkaloid with diverse biological activities. This study aimed to identify the molecular target of BBM against T-2 toxin-induced hepatotoxicity, focusing on autophagy-ER stress crosstalk. We systematically evaluated autophagy and ER stress in human HepaRG cells using immunoblotting, transmission electron microscopy and an autophagy reporter assay. T-2 toxin was found to concurrently activate PINK1/Parkin-mediated mitophagy and suppress Keap1-mediated FAM134B ubiquitination-dependent ER-phagy, thereby triggering ER stress. Integrated evidence from molecular dynamics and western blot demonstrated that BBM upregulated and stabilized BNIP3, blocking the VAMP8-SNAP29 interaction to inhibit T-2 toxin-induced autophagy and subsequent ER stress. Moreover, in vivo mouse experiments demonstrated that 30\u202fmg/kg BBM significantly alleviated T-2 toxin-induced liver injury by suppressing both autophagic flux and ER stress; BBM significantly reduced serum levels of liver enzymes, ALT, and AST. Collectively, our findings elucidate a novel mechanism wherein T-2 toxin-induced mitophagy inhibits ER-phagy to drive ER stress-mediated liver injury and highlight the therapeutic potential of BBM in alleviating T-2 toxin-induced liver injury.",
"41812815": "ID: 41812815\nTitle: Harmine and its derivatives: A promising multi-target therapeutic avenue for Alzheimer's disease.\nAbstract: Alzheimer's disease (AD) is a complex neurodegenerative disorder characterized by \u03b2-amyloid (A\u03b2) deposition, tau hyperphosphorylation, neuroinflammation, and cholinergic dysfunction. Currently, no disease-modifying drugs are available, and existing symptomatic treatments offer limited efficacy while posing safety concerns, highlighting the urgent need for multi\u2011target therapeutic strategies. The natural \u03b2\u2011carboline alkaloid harmine has attracted considerable attention due to its favorable blood-brain barrier penetration and multi\u2011target profile. Accumulating preclinical evidence indicates that harmine can concurrently modulate several core pathological processes of AD. Mechanistically, it potently inhibits dual\u2011specificity tyrosine phosphorylation\u2011regulated kinase 1A (DYRK1A), thereby reducing tau hyperphosphorylation, suppressing aberrant amyloid precursor protein processing, and enhancing neprilysin\u2011mediated A\u03b2 clearance. Concurrently, harmine attenuates neuroinflammation via negative regulation of the Toll-like receptor 4 (TLR4)/nuclear factor kappa B (NF\u2011\u03baB) and NOD-like receptor family pyrin domain containing 3 (NLRP3) inflammasome pathways, improves cholinergic neurotransmission through acetylcholinesterase inhibition, and alleviates glutamate excitotoxicity by upregulating astrocytic glutamate transporter 1/excitatory amino acid transporter 2 (GLT-1/EAAT2) expression. Structurally optimized harmine derivatives have demonstrated enhanced dual inhibitory activity and improved cognitive outcomes in preclinical models. Despite these promising findings, challenges such as pharmacokinetic limitations, insufficient target selectivity, and a lack of clinical data remain. In conclusion, the harmine scaffold represents a mechanistically grounded and promising direction for the development of multi\u2011target therapeutics for AD.",
"41844133": "ID: 41844133\nTitle: IRE1/FAM134B-mediated ER-phagy alleviates zearalenone-induced ER stress and developmental defects in porcine embryos.\nAbstract: Zearalenone (ZEN), a mycotoxin commonly found in animal feed, impairs the female reproductive function owing to its estrogen-mimicking ability. ZEN exposure induces endoplasmic reticulum (ER) stress, oxidative stress, and autophagy activation. However, the involvement of inositol-requiring enzyme 1 (IRE1)-mediated ER-phagy in ZEN-induced ER stress and embryonic competence during in vitro culture (IVC) remains unclear. Porcine embryos were cultured with 2.5, 5, and 10\u202f\u03bcM ZEN for two days after in vitro fertilization (IVF) to assess blastocyst development. ZEN exposure caused a significant dose-dependent decrease in blastocyst formation, expanded blastocysts, and total cell number (p\u202f<\u202f0.05). ZEN-treated embryos exhibited increased DNA fragmentation along with elevated mitochondrial and intracellular Ca\u00b2\u207a levels (p\u202f<\u202f0.001), as confirmed using terminal deoxynucleotidyl transferase dUTP nick-end labeling assay and Rhod-2 and Fluo-4 AM staining. ER-tracker analysis revealed decreased ER fluorescence intensity and increased uneven cytoplasmic ER distribution in blastocysts exposed to 5 and 10\u202f\u03bcM ZEN (p\u202f<\u202f0.001). Western blotting showed activation of the unfolded protein response (UPR) with increased expression of glucose-regulated protein 78 (GRP78), p-IRE1, IRE1, p-c-Jun N-terminal kinase (JNK), JNK, C/EBP homologous protein (CHOP), and the autophagy marker microtubule-associated protein 1 light chain 3 beta (LC3B) (p\u202f<\u202f0.05), whereas the ER-phagy receptor family with sequence similarity 134, member B was downregulated. Tauroursodeoxycholic acid (TUDCA) alleviated ZEN-induced ER stress, restoring ER distribution and calcium homeostasis, reducing DNA damage, and improving blastocyst development. These findings suggest that ZEN disrupts IRE1 signaling and suppresses ER-phagy during early porcine embryo development, whereas TUDCA alleviates ER stress and improves embryonic competence during IVC.",
"41932312": "ID: 41932312\nTitle: Mechanosensory channels mediate ER Ca2+ transients to trigger assembly of autophagosome initiation sites for degradation of ER subdomains.\nAbstract: ER-phagy involves the selective autophagosomal engulfment of ER fragments, but the signaling events, selection mechanisms, and membrane source of ER-phagic autophagosomes remain elusive. Here, using state-of-the-art super-resolution multi-SIM imaging, we reveal that stresses (prolonged starvation, cholesterol dyshomeostasis, and high-Ca2+ insults) trigger the expansion of sheet ER subdomains containing high levels of luminal Ca2+ in mammalian cells, which are subsequently degraded by ER-phagy. Autophagosome formation and sequestration of ER sheets require the concerted actions of FAM134B and lipidated LC3, whereas the autophagy proteins ATG14 and ATG9 are partially dispensable. Electron microscopy and cryo-electron tomography show that the membranes of autophagosomes enclosing high-Ca2+-containing ER sheets are directly remodeled from the ER. The ER-localized cation channels PIEZO1 and TRPV1 are enriched at and mediate Ca2+ transients from high-Ca2+-containing ER sheets, triggering liquid-liquid phase separation of the autophagosome-initiating FIP200 complex to initiate ER-phagy. Thus, distinct mechanisms are employed for the formation of high-Ca2+-containing ER-enclosing autophagosomes and non-selective autophagosomes.",
"41953939": "ID: 41953939\nTitle: FAM134B isoform 2/RETREG1-2 defines a calnexin-TOLLIP-coupled ER-phagy pathway that restricts Ebola virus glycoprotein and is antagonized by VP40 through macro-autophagy.\nAbstract: Selective autophagy of the endoplasmic reticulum (ER-phagy) is critical for ER proteostasis and host defense, yet how ER quality-control pathways interface with ER-phagy to restrict viral glycoproteins remains poorly defined. Previously, the 1st known ER-phagy receptor gene RETREG1 (RETR1)/FAM134B gene was reported to restrict Ebola virus (EBOV) replication in vivo by inhibiting the viral glycoprotein (GP) and viral protein 40 kDa (VP40) expression, but this mechanism remains unknown. Here, we identify the truncated RETR1/FAM134B isoform 2 (RETR1-2), but not its full-length protein RETR1, as an ER-phagy receptor that targets EBOV-GP for degradation. RETR1-2 broadly triggers GP degradation across ebolavirus species but not Marburg virus and inhibits EBOV replication. Mechanistically, RETR1-2 recognizes EBOV-GP via its luminal domain, undergoes GP-induced oligomerization, and directs GP-containing ER membranes to lysosomes through canonical macro-autophagy. Using unbiased mass spectrometry, we identified TOLLIP as the key cytoplasm adaptor for RETR1-2, which also requires cooperation with the ER chaperone calnexin for EBOV-GP degradation. Notably, the PI3P-binding C2 domain of TOLLIP mediates its interaction with RETR1-2, and the EBOV-GP degradation occurs independently of ubiquitination, revealing an unexpected role for TOLLIP in ER-phagy. Furthermore, EBOV-VP40 antagonizes this pathway by selectively targeting RETR1-2 for macroautophagic degradation independently of TOLLIP, thereby restoring GP expression and viral infectivity. Nevertheless, RETR1-2 reciprocally degrades VP40 via a similar mechanism. Together, these findings define a calnexin-TOLLIP-RETR1-2 axis that links ER quality control to ER-phagy-mediated antiviral restriction and uncover a reciprocal host-virus arms race centered on selective macro-autophagy.",

Although estrogen replacement therapy is cardioprotective, its long-term risks are significant. Spermidine, a natural polyamine, is known for its longevity and cardioprotective effects, but its efficacy in models combining accelerated aging-like model and estrogen deprivation is unclear. Seventy female Wistar rats were separated into sham and ovariectomy (OVX) groups. After twelve weeks, sham-operated rats were divided into three groups and treated with distilled water (Sham-V; p.o.), D-galactose (Sham-D; 150\u00a0mg/kg/day; s.c.), and spermidine (Sham-DS; 20\u00a0mg/kg/day; p.o.) for eight weeks. After ovariectomy, the OVX-operated rats were given D-galactose for 12 weeks to accelerated aging-like model, and were subdivided into four groups and treated with distilled water (OVX-D; p.o.), spermidine (OVX-DS; 20\u00a0mg/kg/day; p.o.), sesame oil (OVX-DO; estrogen vehicle; s.c.), and estrogen (OVX-DE; estradiol; 50\u00a0\u00b5g/kg/day; s.c.) for eight weeks. Rats in both accelerated aging-like model and estrogen deprivation groups developed cardiometabolic dysfunction indicated by dyslipidemia, insulin resistance, mitochondrial dysfunction, impaired mitophagy, and apoptosis. Spermidine significantly improved these adverse effects, comparable to estrogen, without altering cardiac senescence and insulin resistance. Spermidine could serve as a potential therapeutic strategy for mitigating cardiometabolic complications in postmenopausal populations.",
"42012729": "ID: 42012729\nTitle: Spermidine in the aging brain: mechanisms, preclinical evidence, and clinical perspectives.\nAbstract: Spermidine, a naturally occurring polyamine, has emerged as a candidate modulator of brain aging because it regulates autophagy, mitochondrial function, oxidative balance, and neuroinflammatory signaling. This review summarizes current knowledge on spermidine biology, including its synthesis, catabolism, transport, and cell-specific handling in neurons and glia, with emphasis on ATP13A2/ATP13A4-dependent trafficking and EP300-linked autophagy. Preclinical studies consistently show that spermidine enhances proteostasis, reduces soluble amyloid-beta, improves microglial phagocytic activity, preserves mitochondrial fitness, and attenuates inflammatory responses in models of aging and neurodegeneration. Human evidence is encouraging but still limited: observational studies associate higher dietary spermidine intake with better cognitive outcomes, whereas interventional trials suggest possible benefits in subjective cognitive decline and mild dementia, with variable dose-dependent effects. Overall, spermidine is a biologically plausible nutraceutical for healthy brain aging, but larger, well-designed clinical trials are needed to define efficacy, bioavailability, safety, and optimal therapeutic use across prodromal, early-stage, and disease-specific patient populations.",
"42013738": "ID: 42013738\nTitle: Spermidine alleviates sepsis-induced cardiomyopathy by improving mitochondrial quality and quantity via a Metallothionein 1-dependent antioxidant pathway.\nAbstract: Sepsis-induced cardiomyopathy (SICM) is characterized by mitochondrial dysfunction, impaired mitophagic flux, and overwhelming oxidative stress. Spermidine (SPD), a natural polyamine known to enhance autophagy and preserve cardiac function in aging and metabolic disorders, has not been systematically evaluated in the context of septic cardiomyopathy. To determine the therapeutic potential and mechanistic basis of SPD in septic cardiac dysfunction. Network pharmacology, RNA sequencing, a cecal ligation and puncture (CLP) mouse model, and multiple cellular assays were integrated to assess the protective actions of SPD. Mitochondrial function, mitophagy flux, and oxidative stress were evaluated using transmission electron microscopy (TEM), immunohistochemistry (IHC), Western blotting, structured illumination microscopy (SIM), mitochondrial membrane potential assays, oxygen consumption rate (OCR) analysis, and mitochondrial DNA (mtDNA) quantification. Transcriptomic clustering and pathway enrichment identified molecular targets, which were validated through siRNA-mediated gene silencing. SPD markedly attenuated SICM in vivo and in vitro by improving both mitochondrial quantity and quality. It restored sepsis-impaired mitophagy by upregulating LC3B and ATG7, promoting autophagosome maturation, and enhancing cellular ubiquitination. Transcriptomic profiling highlighted metallothionein-1 (MT1) as a key node in metal-ion response pathways. SPD activated the NRF2-MT1-SOD2 antioxidant axis, reduced mitochondrial reactive oxygen species (mtROS) under lipopolysaccharide (LPS) stimulation, and reversed sepsis-induced suppression of SOD2. MT1 knockdown abolished SPD-mediated SOD2 stabilization and mtROS clearance, confirming its essential role in SPD's cardioprotective effects. SPD mitigates SICM by orchestrating the restoration of mitochondrial quality control, normalization of mitophagic flux, and stabilization of cellular redox homeostasis. These findings support SPD as a promising therapeutic candidate for septic cardiomyopathy.",
"42045046": "ID: 42045046\nTitle: [Research progress in mechanisms of dietary resistant starch for regulating glucose and lipid metabolism].\nAbstract: The global prevalence of metabolic diseases such as obesity, diabetes, and cardiovascular diseases is closely related to overnutrition and imbalanced dietary patterns. As an important carbohydrate, starch directly affects the homeostasis of glucose and lipid metabolism due to its digestion characteristics. Resistant starch (RS) with unique anti-digestive properties and prebiotic functions has become the current hotspot in dietary nutrition research for improving glucose and lipid metabolism disorders. This review summarizes the digestive characteristics of starch and the comprehensive effects of RS and its mechanisms for ameliorating metabolic diseases. Diets with high RS content not only optimize glucose homeostasis by delaying glucose release, the undigested fractions entering the colon also drive the metabolic regulatory network of the gut microbiota-gut-brain axis by activating the AMPK/ACC pathway to reduce fat accumulation, enhancing intestinal barrier function mediated by short-chain fatty acids (SCFAs), and promoting GLP-1/PYY neural signal transduction. These insights facilitate the design of new healthy foods and inspire new strategies for optimizing dietary nutrition and regulating glucose and lipid metabolism disorders caused by high-carbohydrate diets. \u4ee3\u8c22\u6027\u75be\u75c5\u5982\u80a5\u80d6\u3001\u7cd6\u5c3f\u75c5\u3001\u5fc3\u8840\u7ba1\u75be\u75c5\u7684\u5168\u7403\u6d41\u884c\u4e0e\u8425\u517b\u8fc7\u5269\u53ca\u996e\u98df\u6a21\u5f0f\u5931\u8861\u5bc6\u5207\u76f8\u5173\u3002\u6dc0\u7c89\u4f5c\u4e3a\u4eba\u7c7b\u4e3b\u8981\u80fd\u91cf\u6765\u6e90\u7684\u78b3\u6c34\u5316\u5408\u7269\uff0c\u5176\u6d88\u5316\u7279\u6027\u76f4\u63a5\u5f71\u54cd\u7cd6\u8102\u4ee3\u8c22\u7a33\u6001\u3002\u6297\u6d88\u5316\u6027\u6dc0\u7c89\uff08RS\uff09\u56e0\u5176\u72ec\u7279\u7684\u6297\u6d88\u5316\u7279\u6027\u4e0e\u76ca\u751f\u5143\u529f\u80fd\uff0c\u6210\u4e3a\u5f53\u524d\u6539\u5584\u7cd6\u8102\u4ee3\u8c22\u7d0a\u4e71\u7684\u81b3\u98df\u8425\u517b\u7814\u7a76\u7684\u70ed\u70b9\u3002\u672c\u6587\u7efc\u8ff0\u4e86\u6dc0\u7c89\u6d88\u5316\u7279\u6027\u4ee5\u53caRS\u6539\u5584\u4ee3\u8c22\u6027\u75be\u75c5\u7684\u7efc\u5408\u4f5c\u7528\u53ca\u76f8\u5173\u673a\u5236\u3002\u9ad8RS\u7684\u81b3\u98df\u4e0d\u4ec5\u901a\u8fc7\u5ef6\u7f13\u8461\u8404\u7cd6\u91ca\u653e\u4f18\u5316\u8840\u7cd6\u7a33\u6001\uff0c\u800c\u4e14\u672a\u6d88\u5316\u7684\u90e8\u5206\u8fdb\u5165\u7ed3\u80a0\u901a\u8fc7\u9a71\u52a8\u80a0\u9053\u83cc\u7fa4-\u80a0-\u8111\u8f74\u4ee3\u8c22\u8c03\u63a7\u7f51\u7edc\uff0c\u5176\u4e2d\u5305\u62ec\u6fc0\u6d3b\u817a\u82f7\u9178\u6d3b\u5316\u86cb\u767d\u6fc0\u9176/\u4e59\u9170\u8f85\u9176A\u7fa7\u5316\u9176\uff08AMPK/ACC\uff09\u901a\u8def\u51cf\u5c11\u8102\u80aa\u84c4\u79ef\u3001\u63d0\u5347\u77ed\u94fe\u8102\u80aa\u9178\uff08SCFAs\uff09\u4ecb\u5bfc\u7684\u80a0\u5c4f\u969c\u529f\u80fd\u4e0e\u80f0\u9ad8\u8840\u7cd6\u7d20\u6837\u80bd-1/\u80bdYY\uff08GLP-1/PYY\uff09\u795e\u7ecf\u4fe1\u53f7\u4f20\u5bfc\u3002\u8fd9\u4e0d\u4ec5\u5c06\u4e3a\u65b0\u578b\u5065\u5eb7\u98df\u54c1\u8bbe\u8ba1\u63d0\u4f9b\u7814\u7a76\u57fa\u7840\uff0c\u4e5f\u4e3a\u4f18\u5316\u81b3\u98df\u8425\u517b\uff0c\u8c03\u63a7\u9ad8\u78b3\u6c34\u996e\u98df\u5f15\u8d77\u7684\u7cd6\u8102\u4ee3\u8c22\u7d0a\u4e71\u63d0\u4f9b\u4e86\u65b0\u7684\u7814\u7a76\u601d\u8def\u3002.",
"42051019": "ID: 42051019\nTitle: Multi-Target Neuroprotective Compound Exhibits EAAT2-Modulating and Alzheimer's Pathology-Attenuating Effects in In Vitro and In Vivo Models.\nAbstract: Alzheimer's disease (AD) is a debilitating neurodegenerative disorder characterized by cognitive decline and memory loss. Current treatments offer limited efficacy, necessitating the development of innovative multitarget therapeutic strategies. Here, we present N3,N5-bis(2-(5-methoxy-1H-indol-3-yl)ethyl)-2,6-dimethyl-4-(2-nitrophenyl)pyridine-3,5-dicarboxamide (HCM-01), a novel compound developed to target multiple neurodegenerative pathways implicated in AD. In vitro assays included MTT-based cell viability analyses performed in two complementary experimental settings: primary neuronal cultures and astrocyte-based in vitro cell culture models exposed to glutamate. In primary hippocampal neuronal cultures, glutamate exposure induced a statistically significant reduction in cell viability compared with vehicle-treated controls, consistent with glutamate-induced excitotoxicity. Under these conditions, HCM-01 treatment resulted in a statistically significant improvement in neuronal viability, showing a greater protective effect compared with donepezil and memantine. In contrast, in astrocyte-based in vitro cultures, the applied glutamate concentration did not induce overt cytotoxicity, in line with the intrinsic neuroprotective and glutamate-buffering role of astrocytes. Accordingly, astrocytic experiments were designed to assess functional modulation of glutamate-handling mechanisms rather than cell survival. Western blot analysis in C8-D1A astrocytic cells demonstrated increased expression of excitatory amino acid transporter 2 (EAAT2) following HCM-01 treatment compared with control and reference drug-treated groups, suggesting modulation of astrocyte-mediated glutamate homeostasis. In parallel, redox analyses revealed that HCM-01 improved oxidative/antioxidative balance, as evidenced by increased total antioxidant capacity (TAC) and reduced total oxidant status (TOS), supporting an indirect antioxidant contribution to its functional effects. In vivo behavioral assessment of HCM-01 in a streptozotocin (STZ)-induced Alzheimer's model in female Sprague-Dawley rats demonstrated that administration of HCM-01 at doses of 50 mg/kg orally (oral, P.O. and intraperitoneal, I.P.) and 100 mg/kg (P.O.), significantly improved cognitive and memory functions in the passive avoidance (PA), Morris water maze (MWM), and locomotor activity tests. Moreover, histopathological and immunohistochemical analyses of different hippocampal regions revealed reduced neuronal damage, attenuation of tau pathology, antiamyloidogenic effect, and restoration of cholinergic function. Complementary in silico studies, including molecular docking, molecular dynamics simulations (MDS), and free energy calculations, suggested potential interactions of HCM-01 with the allosteric site of EAAT2. Taken together, these findings suggest that HCM-01 exerts neuroprotective effects against glutamate-induced excitotoxicity in primary hippocampal neurons while additionally modulating glutamatergic homeostasis and redox balance through functional mechanisms in astrocyte-based models, supporting its relevance as a multitarget preclinical candidate for early stage AD mechanisms.",
"42086115": "ID: 42086115\nTitle: Polyamines and autophagy as a dynamic regulatory network in skeletal muscle regeneration and aging.\nAbstract: Autophagy is a core cellular mechanism that preserves tissue homeostasis by removing damaged proteins and organelles. In skeletal muscle, proper regulation of autophagic flux is essential for maintaining metabolic and structural integrity, whereas its disruption contributes to muscle atrophy, metabolic dysfunction, and age-related functional decline. Increasing evidence identifies polyamines, particularly spermidine (Spd), as important modulators of autophagy and cellular resilience, with beneficial effects on stress responses, metabolic regulation, and lifespan extension. Physical exercise likewise acts as a physiological inducer of autophagy, promoting muscle remodelling, mitochondrial quality control, and adaptive responses to stress. Within this framework, spermine oxidase (SMOX) has emerged as a relevant regulator of muscle homeostasis. SMOX expression is maintained in healthy muscle but declines in atrophic conditions. By converting spermine into spermidine, SMOX may help sustain autophagy-related pathways and support muscle mass under physiological conditions. This review explores the interplay between exercise, spermidine, and SMOX, highlighting autophagy as a unifying regulatory axis. We summarize current evidence on their individual and combined roles in preserving muscle function and discuss their potential relevance for promoting healthy muscle aging and counteracting sarcopenia.",

Spermidine (SPD) is known to ameliorate age-related cognitive decline, and the gut microbiota is an important source of SPD. Clostridium butyricum (C. butyricum), a probiotic, can alleviate cognitive decline in individuals with various neurodegenerative diseases, and C. butyricum might generate SPD. However, the role of C. butyricum in natural brain aging and the efficacy of C. butyricum and the metabolite SPD in ameliorating age-related cognitive decline remain unclear. Here, we investigated the effects of C. butyricum and its metabolite SPD on cognitive decline during natural brain aging and the mechanisms underlying these effects. Aged rats\u00a0(aged 17 months, n\u202f=\u202f12 per group) were randomly divided into normal saline (NS), C. butyricum (1\u202f\u00d7108\u223c109 CFU/ml, by gavage for two months) and SPD (6.5\u202fmg/kg/d, by gavage for one month) groups. Compared with the NS group, the C. butyricum and SPD groups presented improved spatial reference and recognition memory, reduced aging marker levels by immunohistochemical staining, improved synaptic plasticity-related tissue structure by transmission electron microscopy and Golgi staining, and increased level of synaptophysin and BDNF by immunofluorescence staining and western blotting in the brain. Furthermore, treatment with C. butyricum and SPD enhanced intestinal barrier function and decreased serum proinflammatory factor levels and brain tissue damage due to oxidative stress. There were no significant differences in relevant indicators between the C. butyricum and SPD groups. In conclusion, C. butyricum and its metabolite SPD may delay the cognitive decline caused by normal brain aging by reducing oxidative stress and inflammation.",

PACS2, a key resident protein at mitochondria-associated endoplasmic reticulum membranes (MAMs), regulates ER homeostasis under various pathological conditions. However, whether sepsis disrupts PACS2-dependent MAM integrity, thereby triggering ER dysfunction and muscle wasting, remains unexplored. We established a sepsis mouse model via cecal ligation and puncture (CLP) and assessed muscle function using compound muscle action potential (CMAP) recording and grip strength measurements. Muscle atrophy was evaluated by H&E staining and Western blotting. PACS2 expression was determined by Western blotting, immunohistochemistry and qRT-PCR. MAM integrity was assessed by immunofluorescence co-localization of IP3R and VDAC1, and ER-phagy (reticulophagy) activation was evaluated by transmission electron microscopy, Western blotting and fluorescence microscopy. To investigate the functional role of PACS2, adeno-associated virus (AAV)-mediated PACS2 overexpression was performed in mouse tibialis anterior muscle and gastrocnemius muscles, followed by RNA-sequencing analysis. The MAPK pathway proteins p-ERK, p-P38 and p-JNK levels were assessed by Western blotting, and the involvement of ERK-MAPK signalling was tested pharmacologically via intraperitoneal injection of the ERK inhibitor SCH772984. Septic mice developed progressive skeletal muscle atrophy (p\u2009<\u20090.001) and dysfunction (p\u2009<\u20090.01), accompanied by 56% reduction in PACS2 expression at 96\u2009h post-CLP (p\u2009<\u20090.01), 25% decrease in MAM integrity (p\u2009<\u20090.05) and subsequent activation of FAM134B-mediated ER-phagy (p\u2009<\u20090.01). AAV-mediated PACS2 overexpression significantly alleviated muscle atrophy by restoring MAM integrity by 28% (p\u2009<\u20090.01), reducing FAM134B expression by 43% (p\u2009<\u20090.01) and attenuating ER-phagy (p\u2009<\u20090.01). Co-immunoprecipitation revealed no detectable direct protein-protein interaction between PACS2 and FAM134B. Transcriptome sequencing and Western blotting analysis demonstrated that PACS2 overexpression specifically activated the ERK-MAPK signalling pathway (55% increase in p-ERK, p\u2009<\u20090.01) without affecting p-P38 or p-JNK levels (p>0.05), which suppressed FAM134B-mediated ER-phagy (p\u2009<\u20090.05) and ameliorated muscle atrophy (p\u2009<\u20090.05) by inhibiting nuclear translocation of TFEB (p\u2009<\u20090.01). Pharmacological ERK inhibition with SCH772984 abolished the protective effects of PACS2 by promoting TFEB nuclear translocation (p\u2009<\u20090.001) and TFEB-mediated FAM134B expression (p\u2009<\u20090.001). Our findings demonstrate that SIM is closely associated with disrupted MAM integrity. PACS2 plays a critical role in maintaining MAM structural integrity and regulating FAM134B-mediated ER-phagy through the ERK-MAPK-TFEB signalling axis, thereby providing novel mechanistic insights and potential therapeutic targets for SIM.",

Nano-selenium (Nano-Se) represents an advanced selenium supplement with robust antioxidant properties, which can mitigate various forms of heavy metal toxicity. However, the role of Nano-Se in alleviating Cd-induced testis damage remains unclear. Family with sequence similarity 134 member B (FAM134B) is the first identified Endoplasmic reticulophagy (ER-phagy) receptor, and the ER-phagy it mediates plays a crucial role in the reproductive system. In this study, Hy-line White roosters were randomly divided into four groups and subjected to a 90-day observation period. Serum samples and testicular tissue samples from roosters were collected for subsequent detection. Hematoxylin-eosin (H&E) staining, periodic acid-Schiff (PAS) staining, ELISA kit detection, Western blotting (WB), immunofluorescence (IF), cellular thermal shift assay (CETSA) and molecular docking techniques were employed to explore the effects of Cd on the reproductive system and the alleviating effect of Nano-Se. In vivo assays revealed that Nano-Se efficiently mitigated testicular atrophy and histological damage triggered by Cd exposure. Nano-Se reversed the Cd-mediated inhibition of steroidogenesis-related proteins, and elevated the expression of Leydig cell markers including 3\u03b2-HSD and INSL3, thereby ameliorating Cd-evoked Leydig cell dysfunction. Consistent with in vivo outcomes, in vitro tests using primary rooster Leydig cells demonstrated that Nano-Se notably restrained Cd-activated ER-phagy and excessive lysosomal acidification. Mechanistically, such protective effects were achieved by blocking TFEB nuclear translocation and preventing the downregulation of FAM134B. This present study provides a foundation for preclinical research for its usefulness as a potential therapeutic for reproductive toxicity induced by environmental heavy metal pollutants.",

This narrative review maps the adverse outcome pathways (AOPs) through which ethanol impairs synaptic function, primarily via interconnected cascades: TLR4/NF-\u03baB-mediated neuroinflammation (triggering microglial activation and pro-inflammatory cytokines TNF-\u03b1, IL-1\u03b2), CYP2E1-driven oxidative stress (generating ROS/RNS, 4-HNE, causing protein carbonylation and mitochondrial dysfunction), and glutamate excitotoxicity (mediated by GluN2B-NMDAR subunit shifts, Ca\u00b2\u207a overload, and astrocytic EAAT2/GLT-1 downregulation). These pathways converge to suppress BDNF/TrkB signaling (via miR-206 and impaired proBDNF cleavage), leading to deficits in synaptic protein synthesis (e.g., Arc) and trafficking (e.g., GluA1 endocytosis via STEP, impaired forward trafficking). Critically, these insults potentiate neuronal apoptosis through intrinsic (ROS/mitochondrial permeabilization, caspase-9/-3) and extrinsic (TNF-\u03b1/TNF-R1, caspase-8) pathways, executing irreversible synaptic loss via caspase-3 cleavage of PSD-95, spectrin, and cytoskeletal collapse. The structural consequences-dendritic simplification, reduced mature spine density, and PSD-95 nano-domain disorganization-manifest functionally as attenuated LTP, potentiated mGluR-LTD, and impaired STDP. This synaptic decay directly underpins cognitive impairments in pattern separation, contextual memory, and cognitive flexibility. Neuroinflammation (TLR4/NF-\u03baB) acts as a central amplifier, linking oxidative damage, excitotoxicity, and BDNF collapse to apoptotic synaptic deletion. Future research must address dose-dependency, subfield vulnerability, epigenetic regulation, and therapeutic strategies targeting TLR4, TrkB, mitochondrial antioxidants, and anti-apoptotic pathways.",

Parthanatos is a subtype of regulated cell death triggered by glutamate excitotoxicity. Interferon-induced transmembrane protein 3 (IFITM3) is an immune regulatory molecule involved in neuronal death in various neurodegenerative disorders. However, it remains unclear whether and how IFITM3 and parthanatos participate in secondary brain injury after ICH. This study aims to investigate whether IFITM3 aggravates neuronal parthanatos by impairing astrocytic glutamate uptake after ICH and to elucidate the underlying mechanisms. Bioinformatics analysis of transcriptome datasets from ICH human patients and mouse models was performed to identify the IFITM3 expression and its potential functions. IFITM3 knockout mice and mice with AAV-mediated astrocytic IFITM3 overexpression were subjected to the ICH model by autologous blood injection. Neurobehavioral tests, Western blot, immunofluorescence staining, glutamate uptake assay, and pharmacological approaches were employed to elucidate the role of IFITM3 in glutamate uptake and neuronal parthanatos. IFITM3 was upregulated and served as a hub gene in immune response and cell death after ICH. IFITM3 knockout improved the sensorimotor and cognitive functions of ICH mice. Conversely, astrocytic IFITM3 overexpression reversed these neuroprotective effects. Specifically, IFITM3 knockout alleviated neuronal excitotoxicity and parthanatos by restoring astrocytic glutamate uptake in the perihematomal region, as evidenced by decreased glutamate levels, oxidative damage, PARP-1 overactivation, PAR overproduction, and nuclear translocation of the AIF-MIF complex. Additionally, IFITM3 knockout reduced p38 MAPK phosphorylation and increased the expression of glutamate transporter EAAT2. Administration of a p38 MAPK inhibitor in IFITM3-overexpressing mice restored EAAT2 expression and attenuated neuronal parthanatos after ICH. Astrocytic IFITM3 upregulation causes impaired glutamate uptake, excitotoxicity, parthanatos, and neurological deficits through p38 MAPK/EAAT2 pathway, highlighting IFITM3 and parthanatos as potential therapeutic targets for ICH.",

Here, we identify ER-phagy as a previously unrecognized adaptive response to ISOXUS, an isoxazole derivative of usnic acid with selective anticancer activity. ISOXUS, a mitochondrial respiratory complex II inhibitor, induces bioenergetic collapse, reactive oxygen species accumulation, and extensive ER-derived vacuolization. Using integrated transcriptomic and metabolomic analyses, we demonstrate that ISOXUS selectively triggers ER-phagy in mitochondria-dependent MCF-7 breast cancer cells, but not in more glycolytic triple-negative MDA-MB-231 cells, revealing a cell-type-specific stress adaptation program. ER-phagy induction is associated with upregulation of the ER-phagy receptor FAM134B and depends on ER stress signalling, as pharmacological ER stress inhibition suppresses this process. Multi-omics profiling uncovers coordinated repression of mitochondrial gene expression together with activation of ER-centered metabolic pathways, including amino acid metabolism, the tricarboxylic acid cycle, and one-carbon folate metabolism. Notably, we also identify UFMylation-related genes (CDK5RAP3, DDRGK1) as novel candidates involved in ER-phagy induced by ISOXUS. Moreover, mitochondrial inhibitors, rotenone and oligomycin, unexpectedly promote, while antioxidant a-tocopherol blocks ISOXUS-induced ER-phagy, and all compounds partially improve cell viability under ISOXUS treatment, implicating ROS-driven ER-phagy as a cytoprotective mechanism. Integrated analyses further reveal activation of the integrated stress response (ISR), dominated by the PERK-ATF4 axis, driving glutamine-dependent metabolic reprogramming and suppression of apoptosis-related pathways. The late-stage autophagy inhibition lowered the glutathione synthesis after ISOXUS treatment. Collectively, our findings uncover a previously unappreciated mitochondria-ER-ISR axis that governs metabolic adaptation to ISOXUS and identifies ER-phagy as a potential therapeutic vulnerability in breast cancer.",

Spermidine has been shown to counteract immunosenescence and induce autophagy in preclinical models, and its levels decline with age in humans. We conducted a double-blind, randomised, placebo-controlled pilot study in 40 adults over 65\u2009years of age following their third SARS-CoV-2 vaccine dose to assess the safety of Spermidine and its effects on vaccine-induced immunity. Daily oral supplementation (6\u2009mg, 13\u2009weeks) was well-tolerated. Vaccine non-responsiveness was common, and non-responders exhibited a distinct immune-senescence signature marked by elevated p16, mTOR signalling, and \u03b3-H2AX+ DNA damage in lymphocytes. Spermidine reversed these features and significantly enhanced spike-specific IgG secretion, memory B cell recall responses and neutralising antibody activity, specifically in non-responders. Single-cell RNA-seq after treatment revealed increased expression of TFEB targets and autophagy-related genes in B cells, in line with elevated autophagic flux. These findings suggest that targeting immune cell senescence with Spermidine may improve vaccine responsiveness in older adults and highlight immune-senescence markers as potential predictors of vaccine failure in ageing populations.",
"42192129": "ID: 42192129\nTitle: FAM134B-mediated ER-phagy degrades APP and suppresses Alzheimer's disease pathology.\nAbstract: Endoplasmic reticulum autophagy (ER-phagy) is a selective autophagy pathway in which receptor proteins target ER membranes and proteins for degradation, yet its role in Alzheimer's disease (AD) remains unclear. Here, we identify FAM134B/RETREG1 as a specific ER-phagy receptor mediating amyloid precursor protein (APP) degradation. FAM134B directly interacts with ER-localized wild-type and familial mutant APP via their C-terminal domains and recruits LC3 through its LC3-interacting region (LIR) to promote APP delivery to phagophores for lysosomal degradation. In AD, epigenetic silencing at the FAM134B promoter suppresses its transcription by limiting TFEB/TFE3 binding despite their nuclear enrichment. This transcriptional suppression impairs ER-phagy, leading to APP accumulation and exacerbated AD pathology. AAV-mediated hippocampal expression of wild-type, but not LIR-mutant, FAM134B in 5XFAD mice restores ER-phagy, enhances APP clearance, reduces A\u03b2 deposition, preserves synaptic and myelin integrity, and improves cognitive performance. These findings establish FAM134B downregulation as an upstream pathogenic event in AD, suggesting ER-phagy enhancement as a promising strategy to suppress A\u03b2 generation at its source.",
"42197044": "ID: 42197044\nTitle: Dietary Polyamine Intake Across Age Groups in Spain: A Comprehensive Assessment.\nAbstract: Polyamines, including putrescine (PU), spermidine (SPD), and spermine (SPM), are ubiquitous bioactive compounds essential for cell proliferation, genomic stability, autophagy, and the regulation of oxidative and inflammatory responses. Growing evidence, particularly for SPD, suggests that polyamine-rich diets may protect against age-related conditions such as cardiovascular disease, metabolic syndrome, and neurodegenerative disorders. As endogenous polyamine synthesis declines with age, dietary intake becomes increasingly important, especially in older adults. This study estimated each polyamine (PU, SPD and SPM) and total polyamine intake in the Spanish population using food consumption data from the Spanish Ministry of Agriculture, Fisheries and Food. Intakes were evaluated across four age groups, and major dietary sources were identified. Total polyamine intake increased with age, reaching 393 \u00b5mol/day in adults over 65 years. PU accounted for 49% of total intake, followed by SPD (29%) and SPM (22%). Plant-based foods were the primary contributors to SPD intake, particularly vegetables (36%), fruits (26%), and cereals (18%). PU intake was also predominantly plant-derived, mainly from fruits (58%) and vegetables (23%), whereas SPM intake was largely associated with meat products (59%). A theoretical Mediterranean diet model yielded a slightly higher total polyamine intake of 406.6 \u00b5mol/day and a substantially greater SPD intake than that observed in older adults (193.99 \u00b5mol/day versus 121.62 \u00b5mol/day). Overall, estimated polyamine intake in the Spanish population fell below the optimal level of 540 \u00b5mol/day proposed in the literature. These findings highlight the need for public health strategies promoting consumption of polyamine-rich foods, particularly vegetables, legumes, whole grains, and fruits, to support healthy aging and reduce the risk of age-related diseases.",

While the gut microbiota is known to shift during host aging, the ecological forces governing the assembly of the reproductive microbiota and its functional feedback on uterine homeostasis remain poorly understood. We demonstrated that uterine aging drives a transition from stochastic to deterministic microbial community assembly, selecting for a microbiota enriched in Rhodococcus in aged laying hens. Multi-omics analyses revealed that this deterministic shift acts as a compensatory mechanism to counteract age-related energy metabolism decline in the uterus. Mechanistically, the aged uterus suffered from oxidative phosphorylation impairment due to PARP1-mediated NAD+\u2009depletion in response to accumulated DNA damage. However, the specific colonization of Rhodococcus ruber, or the administration of its metabolite spermidine, rescued this phenotype. Spermidine improved uterine energy metabolism by inducing PINK1/Parkin-mediated mitophagy, thereby restoring mitochondrial quality control and ATP production essential for eggshell biomineralization. This study uncovers a previously unrecognized role of the microbiota in reproductive aging: resident microbes enhance oxidative phosphorylation in the aged uterus through the metabolite spermidine, which induces mitophagy. This process alleviates cellular energy deficiency caused by PARP1-mediated NAD\u2009+\u2009depletion, elucidating a key mechanism of host-microbe interaction in maintaining uterine energy homeostasis during aging.

Here, we identify the vitamin D receptor (Vdr) as a key anti-aging transcription factor whose expression in granulosa cells (GCs) declines with age. Using GCs-specific Vdr knockout (cVKO) mice and a Vdr-knockout (VKO) human granulosa-like cell line, we demonstrate that loss of Vdr triggers GCs aging and disrupts ovarian function. Integrated transcriptomic and metabolomic analyses from VKO and WT cells revealed that Vdr loss downregulates the de novo spermidine (SPD) biosynthesis by directly suppressing the transcription of ornithine decarboxylase (ODC1). This led to SPD depletion, which in turn inhibited DNA methyltransferase (DNMTs) activity, resulting in hypomethylation of the p53 promoter and activation of the p53/p21 pathway. Crucially, supplementation with either SPD or its upstream methyl donor S-adenosylmethionine (SAM) rescued cVKO and VKO cell aging, improved hormonal profiles and promoted follicular development in cVKO mice. Furthermore, both supplements effectively delayed ovarian aging and improved fertility in naturally aged mice. Our study unveils the Vdr-spermidine-DNMTs axis as a fundamental mechanism safeguarding against ovarian aging, highlighting SPD and SAM as promising therapeutic agents for age-related female infertility.",

Codonopsis pilosula is the sovereign herb in Shenling Baizhu Formula for ulcerative colitis therapy, and Codonopsis pilosula polysaccharides are its key active components, while their immunomodulatory effects and molecular mechanisms in Shenling Baizhu Formula against ulcerative colitis remain elusive. This study explored the critical role of Codonopsis pilosula polysaccharides and the spermidine-AMPK-mediated mitophagy-cGAS-STING inflammatory axis in regulating intestinal inflammation and ameliorating ulcerative colitis. A dextran sulfate sodium-induced ulcerative colitis mouse model was established to evaluate the indispensable role of Codonopsis pilosula polysaccharides in Shenling Baizhu Formula. Ultra-high performance liquid chromatography metabolomics and 16S ribosomal RNA sequencing were performed to identify key metabolites and gut microbiota. In vitro dextran sulfate sodium-induced ulcerative colitis cellular models (human colorectal adenocarcinoma Caco-2 and human normal colonic epithelial NCM460 cells) were constructed to validate the regulatory mechanism of spermidine on AMPK-mediated mitophagy, inflammatory balance and intestinal epithelial injury. Codonopsis pilosula polysaccharides were essential for the anti-ulcerative colitis efficacy of Shenling Baizhu Formula: removal of Codonopsis pilosula significantly aggravated colonic pathological lesions, intestinal inflammatory responses and oxidative stress in ulcerative colitis mice, whereas Codonopsis pilosula polysaccharides supplementation reversed these abnormal phenotypes (P\u00a0<\u00a00.05). Metabolomics and microbiomics confirmed that Codonopsis pilosula polysaccharides exerted therapeutic effects via spermidine (a key metabolite in glutamate metabolism pathway) and Muribaculaceae. Critically, in vitro dual-cell experiments verified that spermidine activated AMPK-mediated mitophagy to directly inhibit the hyperactivation of cGAS-STING inflammatory axis, thereby restoring intestinal inflammatory homeostasis and alleviating epithelial cell injury in ulcerative colitis. Codonopsis pilosula polysaccharides extracted from the sovereign herb Codonopsis pilosula in Shenling Baizhu Formula ameliorate dextran sulfate sodium-induced ulcerative colitis, and the core mechanism depends on spermidine-triggered AMPK-mediated mitophagy to suppress the cGAS-STING inflammatory signaling axis, which plays a pivotal role in regulating intestinal immunity and repairing mucosal epithelial damage.",

Therapeutic strategies targeting aging hallmarks can delay aging and mitigate disease risk. Emerging interventions focus on modulating core aging mechanisms, including cellular senescence, metabolic dysfunction, epigenetic alterations, and mitochondrial impairment, etc. Recent advances have focused on three strategies: senolytics (eliminating senescent cells, e.g., dasatinib + quercetin), senomorphics (inhibiting the senescence-associated secretory phenotype, e.g., rapamycin), and senoreversion (rejuvenating senescent cells via epigenetic reprogramming). Additionally, metabolic interventions such as caloric restriction mimetics (e.g., spermidine, \u03b1-ketoglutarate, ergothioneine) enhance mitochondrial function, activate autophagy, and reprogram energy metabolism, demonstrating lifespan extension and healthspan improvement in preclinical models. Collectively, these approaches hold promise for delaying aging and alleviating age-related pathologies, facilitating the transition to precision longevity medicine. Concurrently, artificial intelligence (AI) accelerates discovery by integrating multiomics data, predicting candidate compounds, identifying biomarkers, and enabling personalized interventions. Despite advancements, challenges remain in target specificity, off-target effects, and clinical translation.

However, the molecular mechanisms linking impairment of redox balance to mitophagy suppression during senescence remain poorly understood. In this study, we identified TIA-1, an RNA-binding protein, as a positive regulator of FUNDC1 expression, a key receptor for ubiquitin-independent mitophagy. Sodium butyrate and ultraviolet-B irradiation triggered oxidative stress-associated senescence in HaCaT cells, leading to reduced TIA-1 expression, decreased FUNDC1 levels, impaired mitophagy flux, excessive mitochondrial elongation, and upregulation of senescence markers. Conversely, ectopic expression of TIA-1 restored FUNDC1 levels, enhanced mitophagy, improved mitochondrial function, and reduced senescence marker expression. Ribonucleoprotein immunoprecipitation assays confirmed that TIA-1 directly interacts with FUNDC1 mRNA, and subsequent analyses indicated that TIA-1 enhances FUNDC1 expression primarily through translational control. Together, these findings establish TIA-1 as a pivotal regulator of mitochondrial homeostasis during cellular stress, acting through FUNDC1 to sustain mitophagy and limit senescence. Targeting TIA-1 may offer new strategies to mitigate mitochondrial dysfunction and restore redox balance in aging and age-related diseases.",

Major hallmarks of aging include oxidative stress, chronic neuroinflammation, mitochondrial dysfunction, and impaired proteostasis. Although caloric restriction (CR) has consistently demonstrated neuroprotective effects, its long-term effects in humans remain challenging. Consequently, CRMs such as metformin, spermidine, and curcumin have been widely used because of their ability to recapitulate key molecular effects of CR. Despite their therapeutic effects, the clinical translation of CRMs is significantly limited by their poor bioavailability, rapid metabolism, low aqueous solubility, and inefficient penetration across the blood-brain barrier (BBB). A nanoparticle-based drug delivery system provides a promising approach to address these limitations. Polymeric, liposomal, and lipid-based nanocarriers can be engineered to increase BBB transport via receptor-mediated transcytosis and to enable targeted and sustained drug release. Encapsulation of CRMs within nanoparticles has improved their pharmacokinetic and pharmacodynamic profiles by increasing their stability and bioavailability and reducing systemic degradation. However, targeted delivery of CRMs has been shown to modulate aging-associated pathways, which are necessary for the maintenance of neuronal integrity and synaptic function. This review highlights the potential of CRM-loaded nanocarriers as emerging therapeutic systems to delay brain aging and age-associated disorders. Furthermore, the current challenges and future perspectives on optimizing brain-targeted delivery to enable successful clinical translation in age-related NDDs are discussed.",

Here, we investigated whether the polyamine biosynthetic enzyme S-adenosylmethionine decarboxylase 1 (AMD1) regulates tubular senescence and repair outcomes after AKI and elucidated the underlying mechanism. AMD1 dynamics were examined in an ischemia-reperfusion injury model using male C57BL/6J mice by immunofluorescence. AAV-mediated Ksp promoter-driven tubule-specific Amd1 conditional knockdown male mice (Amd1 cKD) were used to assess renal injury, cell-cycle status, senescence, and remodeling, and exogenous spermidine was administered for rescue. DNA damage signaling and p53/p21 activation were evaluated by immunostaining, Western blotting, and EdU incorporation assays. AMD1 was predominantly expressed in the tubular epithelium, with prominent dynamic induction in proximal tubules early after IRI, but declined to baseline levels during the late phase, representing a relative metabolic insufficiency that correlated inversely with fibrosis. Compared with wild-type controls, Amd1 cKD mice exhibited aggravated tubular injury, an over two-fold increase in SA-\u03b2-gal-positive areas, elevated p21, and reduced Ki67+ proliferation. Conversely, spermidine supplementation improved renal function, reduced fibrosis by 75.3%, and decreased senescent regions by 74%. Mechanistically, AMD1 deficiency increased \u03b3H2AX-marked DNA damage and activated the p53/p21 checkpoint, whereas spermidine attenuated this response and restored DNA synthesis capacity. Collectively, tubular AMD1 acts as a metabolic checkpoint that preserves polyamine homeostasis to restrain p53/p21-dependent senescence, promote adaptive repair after AKI, and spermidine supplementation represents a potential strategy to mitigate maladaptive AKI-to-CKD progression.",

One hypothesis is based on the proteolytic activation of the serine protease trypsinogen by the lysosomal enzyme cathepsin B (CTSB) after co-localization in the same subcellular compartment. The ER-cargo receptor protein CLN8 (ceroid lipofuscinosis, neuronal) mediates cathepsin transport from the endoplasmic reticulum (ER), the site of enzyme synthesis, to the trans-Golgi system, from which they are distributed to their final destinations. The aim of this study is to investigate the role of CLN8 in acute pancreatitis and intracellular cathepsin trafficking by using isolated pancreatic acinar cells, a CLN8-deficient (Cln8mnd/MsrJ) mouse model, and 266-6 mouse pancreatic acinar tumor cells in which the Cln8 gene was inactivated by CRISPR/Cas9. Loss of CLN8 mitigated the early phase of acute pancreatitis but did not prevent it completely. We still observed CTSB expression in the endo-lysosomal and secretory compartment albeit enzyme activation was decreased. At later disease stages pancreatic injury increased along with an upregulation of ER-phagy shown by an overexpression of LC3B and the ER-phagy receptor FAM134B as well as autophagolysosome formation and increased ER stress. In summary, our data show that acute pancreatitis still occurs despite disruption of the EGRESS (ER-to-Golgi relaying of enzymes of the lysosomal system) complex implicating alternative intracellular enzyme delivery routes. They also illustrate that ER-stress and ER-phagy aggravate severity at later course of pancreatitis.",

This reduced resilience is believed to be underpinned by the hallmarks of ageing, the key biological mechanisms driving the aged phenotype. Geroprotectors are drugs that are proposed to slow down the ageing process and promote longevity and healthspan. Despite this, mechanistic studies in healthy older adults are lacking. This trial will test the hypothesis that geroprotectors targeted towards biological mechanisms associated with poor resilience can reverse these pathways within a three-week period. Three geroprotectors with a good safety profile in older adults and evidence of effect on the hallmarks of ageing will be administered to 60 (30 female; 30 male) adults 70\u2009+\u2009. Participants will be randomised to one of three arms (Metformin MR 1500 mg, Fisetin 100 mg or Spermidine 15 mg). Participants will be extensively clinically characterised at baseline. Blood, abdominal adipose tissue and stool samples will be taken at baseline and following the three-week intervention. The primary research question will answer whether a three-week course of Metformin, Spermidine, or Fisetin reduce the number of senescent cells as measured by SA-\u03b2-GAL in adipose biopsies in healthy older volunteers.

Excess ER generated during a stress response is degraded by a selective type of autophagy known as ERphagy/reticulophagy. A recent study provides a mechanism by which cholesterol levels regulate ERphagy, STING1 activation, and cholesterol biosynthesis. Elevated ER cholesterol levels suppress ERphagy by reducing RETREG1/FAM134B interactions with the autophagy-related protein MAP1LC3/LC3 and the lysosomal protein LAMP2. The study shows that cholesterol directly binds to RETREG1 and SCAP, facilitating the formation of the RETREG1-SCAP complex. Sequestration of RETREG1 in this manner prevents it from performing its ERphagy functions. Furthermore, RETREG1 also interacts with STING1 and is important for its activation in response to viral infections. SCAP-RETREG1 complex formation also reduces the STING1 response. Thus, this study links lipid metabolism, innate immunity, and autophagy, emphasizing a central role for cholesterol in these processes.",

There is an urgent clinical need for highly effective and low-toxicity radioprotective agents. Spermidine (SPD) is a natural polyamine widely found in various foods with well-documented health-promoting properties, yet its role in RIII remains elusive. Using a mouse model of whole-abdominal irradiation, we demonstrated that SPD intervention significantly improved survival rates and mitigated intestinal pathological damage, including crypt loss and villus shortening. Mechanistically, SPD pretreatment activated the Nrf2 signaling pathway, thereby alleviating oxidative stress and reducing DNA double-strand breaks in intestinal epithelial cells. Furthermore, SPD preserved intestinal barrier integrity by enhancing the expression of tight junction proteins (Occludin and ZO-1) and reduced systemic inflammation (serum IL-6). 16S rRNA sequencing revealed that SPD prevented radiation-induced gut dysbiosis by significantly enriching beneficial butyrate-producing bacteria (e.g., Lachnospiraceae_NK4A136_group) while suppressing potential pathogens (e.g., Parabacteroides and Mucispirillum). Our study reveals that SPD exerts multi-targeted protection against RIII by coordinately regulating the \"microbiota-barrier-inflammation\" axis, positioning it as a promising candidate for preventing and treating RIII.",

While fetal lung signals are known to help initiate labor, the role of the placenta has remained unclear. Here we show that in steroid receptor coactivator (Src)-1 and -2 double-knockout mice, reduced placental amine oxidase, copper-containing 1 (Aoc1) leads to increased spermidine levels. In trophoblast cells, spermidine induces autophagy via hypusination of eukaryotic translation initiation factor 5\u2009A (EIF5A), reducing estrogen and prostaglandin production. Estrogen reciprocally increases Aoc1 expression via estrogen receptor-\u03b1 (ER\u03b1) in concert with SRC-1/2, forming a feedback loop maintaining placental autophagy homeostasis. AOC1 levels are elevated in preterm labor placentas from both mice and humans. Placenta-specific Aoc1 knockout dramatically delays labor by increasing trophoblast autophagy. Importantly, spermidine supplementation rescues inflammation-induced preterm labor in mice. Our findings reveal that placental AOC1-spermidine-EIF5A-autophagy axis is essential for parturition timing and offer a potential therapeutic strategy for preterm birth.",

Treatment with NaB (10 and 50 \u00b5M) significantly improved cell viability compared to the LPS\u2009+\u2009A\u03b2 group (p\u2009<\u20090.001) and attenuated apoptosis, as evidenced by reduced expression of Bax, Caspase-3, and FOXO3a (p\u2009<\u20090.0001), alongside upregulation of the anti-apoptotic marker Bcl-2 (p\u2009<\u20090.01). Moreover, NaB markedly increased the expression of neuroprotective and antioxidant genes, including BDNF, Nrf2, SIRT1, and CREB (p\u2009<\u20090.001), thereby restoring pathways involved in neuronal survival, oxidative stress defense, and synaptic plasticity. Collectively, these effects mitigated LPS\u2009+\u2009A\u03b2-induced cytotoxicity, suggesting that NaB exerts its neuroprotective action through epigenetic regulation of stress-response and plasticity networks. Our findings provide robust evidence supporting sodium butyrate as a promising therapeutic candidate for preventing or slowing AD-related neuronal degeneration and highlight its potential translational relevance for future in vivo and clinical investigations.",
"42341668": "ID: 42341668\nTitle: Multi-scale structural evolution and fermentation characteristics of four types of lentil resistant starches by human gut microbiota in vitro.\nAbstract: The multi-scale structural evolution and fermentation characteristics of four types of lentil resistant starch (RS2, RS3, RS4, RS5) were examined during vitro human fecal fermentation. Structural analyses indicated a significant reduction in molecular weight for RS2, RS4, and RS5. Crystalline forms were maintained in RS2 (C-type), RS3 (B-type), and RS4 (A-type), whereas RS5 (V-type) underwent a polymorphic transition to an A-type crystalline pattern. Increases in double-helical order and relative crystallinity were observed in RS2 and RS4, indicating preferential microbial degradation of amorphous regions. Scanning electron and confocal laser microscopy revealed extensive structural deterioration, including pitting, surface erosion, and internal fragmentation in RS2, RS4, and RS5, whereas RS3 exhibited only minor surface alterations. Short-chain fatty acid production was highly dependent on specific multi-scale structural features, including crystalline polymorph, molecular weight, and double-helical order. RS2 generated the highest levels of acetate and propionate, whereas RS3 yielded the greatest quantities of butyrate and valerate. Although microbial diversity decreased across all RS groups, distinct taxonomic changes were detected. Specifically, RS2 and RS4 promoted the growth of Ruminococcus, RS3 enriched Roseburia, and RS5 markedly stimulated Bifidobacterium and Megamonas. These findings demonstrate that the specific structure of resistant starch governs its fermentability, SCFA profile, and impact on microbial composition, highlighting the potential for structurally tailored RS to modulate gut health.",
"42343845": "ID: 42343845\nTitle: [Trillium tschonoskii Maxim saponin protects neurological function in rats with post-stroke cognitive impairment by promoting ER-phagy].\nAbstract: To investigate the mechanism that mediates the neuroprotective effects of Trillium tschonoskii Maxim (TTM) against post-stroke cognitive impairment (PSCI) in rats. Adult SD rats were randomized into Sham operation, PSCI model, TTM, rapamycin (an autophagy inducer), 3-methyladenine (an autophagy inhibitor), and TTM+3-MA groups, and rat models of cognitive impairment were established using a modified thread occlusion method. Cognitive function of the rats was assessed using Morris water maze test. Histopathological changes, neuronal apoptosis, dendritic spines, and protein expressions of FAM134B, LC3, ATG5, P62, GRP78, Bax, Bcl-2, IL-10, IL-1\u03b2, and TNF-\u03b1 were evaluated using HE, Nissl, TUNEL, Golgi staining, immunohistochemistry, immunofluorescence staining, and Western blotting. Compared with the sham-operated rats, the rat models of PSCI showed significantly prolonged escape latency, reduced target quadrant time and platform crossings, severe hippocampal damage, increased ATG5 and GRP78 expression, elevated apoptosis, increased IL-1\u03b2, TNF-\u03b1, Bax, GRP78, and P62 expressions, and decreased IL-10, Bcl-2, and LC3 expressions, with slightly increased FAM134B-LC3 and calnexin-LC3 co-localization. Compared with those in the model group, the rats receiving TTM treatment showed significantly shortened escape latency, increased target quadrant time and platform crossings, increased ATG5 and dendritic spines, decreased GRP78 expression, enhanced FAM134B-LC3 and calnexin-LC3 co-localization, reduced IL-1\u03b2, TNF-\u03b1, Bax, GRP78, and P62 expressions, and increased FAM134B, ATG5, LC3, IL-10, and Bcl-2 expressions; the rats treated with 3-MA showed the opposite changes. Excessive ER stress is activated early after stroke, shifting from adaptive to pro-apoptotic signaling, with insufficient ER-phagy flux. TTM modulates ER-phagy, alleviates ERS, reduces neuroinflammation and apoptosis, protects dendritic spines, and improves cognitive function in rats with PSCI. \u76ee\u7684:

"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 (PPAR\u03b1/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.",
"42346630": "ID: 42346630\nTitle: Sulforaphane as a Photoprotective Agent Against UV-Induced Skin Damage and Carcinogenesis: A Scoping Review.\nAbstract: Background/Objectives: Ultraviolet (UV) radiation is a major environmental carcinogen responsible for skin damage through oxidative stress, DNA damage, and inflammation. The nuclear factor erythroid 2-related factor 2 (Nrf2) pathway plays a central role in regulating cellular antioxidant defences against UV-induced damage. This scoping review aims to evaluate the potential role of sulforaphane (SFN), a known Nrf2 inducer, in protecting against UV-induced skin damage and photocarcinogenesis. Methods: A literature search was conducted in PubMed and Scopus from inception to 27 January 2026, to identify original experimental studies investigating SFN, glucoraphanin, or broccoli sprout extracts in the context of UV-induced skin damage. Eligible studies included in vitro, ex vivo, in vivo, and human models assessing outcomes related to oxidative stress, inflammation, molecular signalling pathways, and tumour development. Following screening and eligibility assessment, twelve studies were included in the qualitative synthesis. Results: The included studies suggest that SFN exerts photoprotective effects across multiple experimental models. In murine studies, SFN and SFN-rich extracts were associated with a reduction in tumour incidence, multiplicity, and volume following UV exposure. In human studies, topical SFN application reduced UV-induced erythema and induced cytoprotective enzyme expression, although clinical evidence remains limited. Mechanistically, SFN consistently activated the Nrf2 pathway, leading to increased expression of antioxidant and phase II detoxifying enzymes, and was associated with modulation of inflammatory responses and inhibition of MAPK/AP-1 signalling. Emerging evidence also indicates potential effects on UV-induced metabolic and epigenetic alterations. Conclusions: Current evidence supports a potential role for sulforaphane in mitigating UV-induced skin damage through activation of endogenous defence pathways. However, the available data are predominantly preclinical, and further well-designed clinical studies are needed to clarify its efficacy and translational relevance in humans.",
"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-\u03baB 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, \u226512 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.",
"42352383": "ID: 42352383\nTitle: Alginate Oligosaccharide Alleviates Severe Acute Pancreatitis in Mice via Suppression of Oxidative Stress, Inflammation and Modulation of Intestinal Epithelial Barrier Integrity.\nAbstract: Severe acute pancreatitis (SAP) is a life-threatening inflammatory disorder characterized by high mortality and limited therapeutic options. Alginate oligosaccharide (AOS), a marine-derived bioactive polysaccharide, exhibits prebiotic, anti-inflammatory and antioxidant properties that are effective against various inflammatory diseases. In this study, a mouse model of SAP was established by intraperitoneal injection of cerulein (100 \u03bcg/kg) and lipopolysaccharide (5 mg/kg), and the mice were pretreated with AOS (200 mg/kg) by gavage for 4 consecutive weeks to explore the potential protective efficacy and underlying mechanisms. The results shown that AOS attenuated the severity of SAP, as evidenced by reduced serum amylase and lipase levels, as well as alleviated histopathological injury in both pancreatic and ileal tissues. AOS suppressed the overproduction of pro-inflammatory cytokines (IL-1\u03b2, IL-6, TNF-\u03b1) in serum, pancreas, and ileum at protein or mRNA levels. Moreover, AOS effectively diminished pancreatic and ileal inflammatory infiltration and oxidative stress in SAP mice, accompanied by inhibited the TLR4/MyD88/NF-\u03baB pathway and activated the Nrf2/HO-1 antioxidant axis. Furthermore, AOS restored intestinal barrier integrity, as manifested by upregulated expression of tight junction proteins (claudin-1, occludin, ZO-1), reduced serum diamine oxidase, and decreased bacterial translocation from the gut to the pancreas. It was revealed by 16S rRNA sequencing that AOS ameliorated SAP-induced gut dysbiosis by restoring microbial diversity, normalizing the Firmicutes/Bacteroidetes ratio, enriching beneficial genera (Lactobacillus, Blautia), and enhancing cecal short-chain fatty acid (acetic, propionic, butyric acid) production. Collectively, our findings demonstrate that AOS exerts comprehensive protective effects against SAP through suppression of inflammatory signaling and oxidative stress, as well as restoring gut homeostasis. These results suggest that AOS may serve as a promising prebiotic-based nutritional strategy for the management of SAP.",

However, the pathogenesis of CI\u2011AKI remains to be fully elucidated. Sulforaphane (SFN), a NRF2 agonist, exhibits anti\u2011inflammatory, antioxidant and anti\u2011apoptotic effects, thus SFN exerts protective effects in kidney injury diseases. However, the possible role and underlying mechanisms of SFN in CI\u2011AKI remain ambiguous. An in vivo model of CI\u2011AKI was constructed using C57BL/6 mice that were administered a single intraperitoneal cisplatin injection (20 mg/kg) and conditionally treated with SFN (10 mg/kg). Serum creatinine (Scr) and blood urea nitrogen (BUN) levels were detected by biochemical analysis. Western blotting was performed to assess the expression of renal injury markers, as well as the apoptosis\u2011related proteins cleaved caspase\u20113, caspase\u20113, Bax and Bcl\u20112. Furthermore, hematoxylin and eosin and periodic acid\u2011Schiff staining were employed to detect renal tissue lesions in mice, and TUNEL staining was used to evaluate the apoptosis of renal tissues in each group in vivo. Immunohistochemistry was used to assess the expression of inflammatory marker F4/80 in mouse renal tissues, and ELISA was used to detect the expressions of the inflammatory markers IL)\u20111\u03b2, IL\u20116 and tumor necrosis factor\u2011\u03b1 (TNF\u2011\u03b1) in the serum of mice in each group. DCFH\u2011DA) analysis was used to detect reactive oxygen species (ROS) levels and biochemical analysis was used to evaluate the expression levels of malondialdehyde, superoxide dismutase and glutathione. Finally, western blotting and immunohistochemistry were performed to evaluate the expression of NRF2. An in vitro model of CI\u2011AKI was constructed using HK\u20112 cells induced by cisplatin (10 \u00b5g/ml) that were conditionally treated with one or both of SFN (5 \u00b5M) and the NRF2 inhibitor ML385 (1.9 \u00b5M). Reverse transcription\u2011quantitative PCR was performed to evaluate the expression of NRF2. Cell Counting Kit\u20118 assay was performed to assess the viability of HK\u20112 cells in different groups, whereas flow cytometry was used to assess the apoptosis of HK\u20112 cells in different groups. DCFH\u2011DA analysis was performed to evaluate the expression of ROS in different treatment groups. Furthermore, ELISA was used to evaluate the expressions of IL\u20111\u03b2, IL\u20116 and TNF\u2011\u03b1 in each group. SFN notably decreased the serum levels of Scr and BUN and decreased the expression levels of kidney injury molecule\u20111 and neutrophil gelatinase\u2011associated lipocalin in the cisplatin\u2011induced model group. Histopathological examination revealed attenuated renal structural damage and preserved tubular architecture in the SFN intervention group. Furthermore, SFN notably inhibited the apoptosis, inflammation and oxidative stress of renal tissues induced with cisplatin. Additionally, SFN markedly upregulated NRF2. In vitro, the NRF2 inhibitor ML385 partially attenuated the effects of SFN on the viability, apoptosis, inflammation and oxidative stress of HK\u20112 model cells. The present study indicated that SFN exerted its nephroprotective effect through NRF2\u2011mediated anti\u2011inflammatory, antioxidant and anti\u2011apoptotic mechanisms, positioning SFN as a promising therapeutic candidate for clinical management of chemotherapy\u2011associated kidney injury.",
"42369899": "ID: 42369899\nTitle: Second-Generation of Deuterium-Substituted Glutamate Uptake Enhancers Exhibit Superior Drug-Like Properties in Preclinical Evaluation.\nAbstract: Strategic deuterium-hydrogen exchange applied to the first-in-class positive allosteric modulators (PAMs) of the glutamate transporter EAAT2/GLT-1, ( R )-AS-1 and ( R )-AS-7, yielded novel analogues with improved drug-like properties. Specifically, incorporation of deuterium into the pyrrolidine-2,5-dione ring significantly prolonged the elimination half-life and increased both plasma and brain exposure in mice. These enhancements translated into more sustained antiseizure activity and a more favorable pharmacokinetic/pharmacodynamic (PK/PD) relationship. Similar to their nondeuterated counterparts, the new deuterated analogues displayed broad-spectrum antiseizure efficacy across multiple in vivo mouse seizure models, including maximal electroshock (MES), 6 Hz (32/44 mA), acute pentylenetetrazole (PTZ), and PTZ-induced kindling. Among these compounds, d 6 -( R )-AS-7 demonstrated the most robust antiseizure effects and the most advantageous overall pharmacokinetic profile following both intraperitoneal and oral administration. Mechanistic studies revealed that d 6 -( R )-AS-7 markedly enhanced glutamate uptake in COS-7 cells expressing EAAT2 as well as in primary astrocyte cultures. Furthermore, electrophysiological recordings in acute mouse hippocampal slices, together with two-electrode voltage-clamp recordings in Xenopus laevis oocytes expressing EAAT2, confirmed increased transporter-mediated currents. Collectively, these findings identify d 6 -( R )-AS-7 as a potent EAAT2 PAM with improved pharmacokinetic properties and strong antiseizure efficacy, supporting its further development as a therapeutic candidate for epilepsy and other disorders associated with glutamate excitotoxicity.",
"42379536": "ID: 42379536\nTitle: Ethnopharmacological potential and mechanistic study of Platycodon grandiflorum stems and leaves and Lonicera japonica stems and leaves against acute lung injury.\nAbstract: Platycodon grandiflorum and Lonicera japonica are two plants that have been widely used in traditional ethnic medicine for both medicinal and edible purposes. They are commonly applied in the prevention and treatment of lung-heat-related and inflammatory diseases. However, the stems and leaves of these plants have historically been regarded as by-products, and their therapeutic potential has not been thoroughly explored. Recent studies have shown that the Platycodon grandiflorum stems and leaves, and Lonicera japonica stems and leaves are rich in bioactive compounds, including flavonoids, saponins and phenolic compounds and exhibit notable anti-inflammatory and antioxidant activities. In this study, we investigate the protective mechanism of Platycodon grandiflorum stems and leaves and Lonicera japonica stems and leaves (PLSL) against lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice. This work aims to provide a theoretical basis for resource development and the sustainable, high-value utilization of non-medicinal parts of traditional Chinese medicinal plants. In this study, an LPS-induced inflammatory model using RAW264.7 cells was employed to screen the optimal compatible ratio of PLSL. High-performance liquid chromatography (HPLC) was used to analyze its chemical composition and identify the main active components. In the animal experiment, a mouse model of ALI was established by intranasal instillation of LPS. The severity of lung injury was comprehensively evaluated based on the lung index, lung wet-to-dry (W/D) weight ratio, hematoxylin and eosin staining and Masson's staining. Levels of inflammatory cytokines, including interleukin-6 (IL-6), tumor necrosis factor-\u03b1 (TNF-\u03b1) and interleukin-1\u03b2 (IL-1\u03b2) were measured using ELISA. The transcriptional levels of genes related to the Keap1/Nrf2 pathway were detected by quantitative real-time polymerase chain reaction (qRT-PCR), and the expression and nuclear translocation of Nrf2 and p65 proteins were assessed by immunofluorescence. Meanwhile, 16S rRNA high-throughput sequencing was applied to analyze the cecal microbiota composition in mice, and gas chromatography was used to determine short-chain fatty acid (SCFA) concentrations. Spearman correlation analysis was performed to explore correlations among inflammatory mediators, antioxidant markers and gut microbiota at the genus level. The in vitro results demonstrated that the 4:1 combination of PLSL promoted the migration and proliferation of RAW264.7\u202fcells in a dose-dependent manner and effectively inhibited the overexpression of pro-inflammatory mediators, including cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS), as well as inflammatory cytokines such as TNF-\u03b1, IL-6 and IL-1\u03b2. Meanwhile, PLSL exhibited strong scavenging activity against 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals, 2,2'-azinobis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) cation radicals and hydroxyl radicals (\u00b7OH). HPLC analysis revealed that PLSL contained key active components, including platycodin D, lobetyolin, loganin and chlorogenic acid. In vivo experiments confirmed that PLSL significantly alleviated LPS-induced ALI in mice by regulating the NF-\u03baB and Keap1/Nrf2 signaling pathways, reducing malondialdehyde (MDA) and nitric oxide (NO) levels, increasing glutathione (GSH) levels, suppressing the expression of COX-2, iNOS, TNF-\u03b1, IL-6 and IL-1\u03b2 and modulating the mRNA expression of Keap1, Nrf2, heme oxygenase-1(HO-1) and NAD(P)H quinone oxidoreductase 1 (NQO1). Furthermore, PLSL effectively improved intestinal microbial diversity, increased the relative abundance of beneficial bacteria, including Lachnospiraceae and Alistipes, and significantly elevated cecal short-chain fatty acids (SCFAs), such as acetic acid, propionic acid and butyric acid. This study preliminarily elucidates the multi-target synergistic anti-inflammatory effects of PLSL from the perspectives of inflammatory signaling pathways and gut microbiota. It provides experimental evidence for the whole-plant development and utilization of Platycodon grandiflorum and Lonicera japonica as ethnomedicines.",
"42392052": "ID: 42392052\nTitle: Psychological stress drives aging-like hematopoietic stem cell dysfunction through a brain-gut-bone marrow axis.\nAbstract: Chronic stress influences hematopoietic stem cells (HSCs). However, how psychological stress regulates HSC function remains incompletely understood. Here, we show that psychological stress impairs HSC self-renewal and lymphoid differentiation, inducing aging-like phenotypes. Stress suppresses neuronal activity in the medial prefrontal cortex (mPFC) and periaqueductal gray (PAG), leading to HSC dysfunction, whereas chemogenetic activation of these regions restores HSC function. Psychological stress or chemogenetic inhibition of the mPFC and PAG reduces the abundance of L. reuteri in the gut microbiota and lowers spermidine levels. Mechanistically, spermidine depletion suppresses mitochondrial autophagy, promotes mitochondrial peroxidative stress, and increases ferroptotic stress in HSCs. We further demonstrate that mPFC and PAG activity regulate the intestinal environment through a sympathetic pathway, reducing intestinal mucin levels, L. reuteri abundance, and spermidine levels. These findings identify a brain-gut-bone marrow axis linking psychological stress to aging-like HSC dysfunction through sympathetic regulation of intestinal microbiota and spermidine metabolism.",
"42396672": "ID: 42396672\nTitle: Combining sequence-based approaches with anaerobic microbiology and modelling to understand gut microbial communities.\nAbstract: Gut micro-organisms possess biochemical capabilities that far exceed those of their mammalian hosts, particularly in the ability to gain energy from the breakdown of diet-derived plant material (fibre). This article reviews investigations into gut microbial communities conducted by Harry Flint and his research group. First, extracellular cellulosome and amylosome enzyme complexes were found to mediate the breakdown of plant cell walls and resistant starch by specialised Firmicutes bacteria, both in the human colon and in the rumen. In contrast, Bacteroidetes (Bacteroides, Prevotella spp.) rely on their ability to capture soluble carbohydrates. Human dietary studies examining the impact of fibre sources upon microbiota composition and metabolism identified 'diet-responsive' species. In addition, dominant species of butyrate-producing bacteria, including a subset able to convert lactate to butyrate, were isolated from healthy human volunteers. Most produce butyrate from carbohydrates via butyryl-CoA:acetate CoA-transferase, with uptake of external acetate, while lactate conversion is associated with a highly inducible gene cluster (lct). In pH-controlled chemostat studies, mildly acid pH depressed growth of propionate-producing Bacteroidetes, but favoured butyrate production by Firmicutes. This may explain why % butyrate among SCFA increases with total faecal SCFA concentration in human studies. Although lactate is normally consumed by lactate-utilising bacteria, destabilisation of the microbial community associated with lactate accumulation can result in radically altered microbiota and metabolite profiles. A theoretical model based on microbial functional groups (MFG) was developed to better understand community dynamics. Consequences for nutritional research of our expanding knowledge of the microbial ecology of the human gut are considered.",

While its systemic toxicity is recognized, its neurotoxic effects in birds, and effective countermeasures, remain underexplored. Sodium butyrate (NaB), a green feed additive, has shown broad biological benefits, but its potential to alleviate T-2-induced neurotoxicity is unclear. This study aimed to investigate the neurotoxic mechanisms of T-2 toxin in quails and evaluate the protective role of sodium butyrate. Two-hundred-and-forty 10-day-old quails were randomly assigned to Control, T-2 toxin (0.9\u00a0mg/kg), NaB (500\u00a0mg/kg), and T-2+NaB groups. After 14 and 28 days, brain tissues were collected for histopathological (hematoxylin-eosin [HE], Nissl, Fluoro-Jade B [FJB] staining) and molecular analyses (RT-qPCR, Western blot, semi-quantitative PCR) to assess oxidative stress, inflammation, and endoplasmic reticulum (ER) stress. T-2 toxin induced severe brain damage, characterized by neuronal vacuolization, loss of Nissl bodies, and degeneration. It concurrently activated oxidative stress (upregulated Nrf2 [nuclear factor erythroid 2-related factor 2], HO-1 [heme oxygenase-1], NQO1 [NAD(P)H: quinone oxidoreductase 1]), neuroinflammation (elevated TNF-\u03b1 [tumor necrosis factor-alpha], IL-1\u03b2 [interleukin-1 beta], IL-6 [interleukin-6], IL-18 [interleukin-18]), and ER stress (increased GRP78 [glucose-regulated protein 78], IRE1\u03b1 [inositol-requiring enzyme 1 alpha], TRAF2 [TNF receptor-associated factor 2], IKK\u03b1/\u03b2 [I\u03baB kinase alpha/beta], XBP1 [X-box binding protein 1]). Sodium butyrate supplementation significantly mitigated these histopathological alterations and downregulated the overactivated molecular pathways across all three axes. This study demonstrates that sodium butyrate confers comprehensive neuroprotection against T-2 toxin in quails by co-ordinately alleviating oxidative stress, neuroinflammation, and ER stress. These findings provide a mechanistic basis for using NaB as a dietary intervention to combat mycotoxin-related neurotoxicity in poultry.",

By systematically comparing allergic phenotypes, gut microbiota remodeling, and short-chain fatty acids (SCFAs) profiles among groups receiving single interventions-Type 3 lotus seed resistant starch (LRS3), sodium acetate (AC), Bifidobacterium animalis subsp. lactis DSM 10140 (BA)-and combined interventions (LRS3-AC, LRS3-BA), a multi-level correlation network of \"gut microbiota-SCFAs-immune markers\" was constructed. This study found that single interventions with LRS3, AC, and BA, as well as combined interventions with LRS3-AC and LRS3-BA, all improved allergy-related symptoms and immune dysregulation, with the LRS3-BA group showing the best intervention effect; all intervention groups shifted the gut microbiota structure away from the allergic state. LRS3 promoted the proliferation of Bifidobacterium, and when combined with BA, further promoted Bifidobacterium to become a core indicator bacterium. All intervention groups significantly increased fecal acetic acid concentration, the acetic acid level in the LRS3-BA group reached 2.15\u00a0\u03bcg/mg. As a common downstream effector molecule, acetic acid showed a strong positive correlation with Bifidobacterium and exhibited a stronger association with allergy markers than propionate and butyrate. The study proposed a potential \"LRS3-Bifidobacterium-acetic acid\" axis for regulating the gut microbiota and alleviating food allergies, providing a theoretical basis for developing food allergy intervention strategies targeting the gut microbiota.",
"42407371": "ID: 42407371\nTitle: Mupirocin-mediated downregulation of claudin-14 enhances chemosensitivity in human colorectal cancer cells.\nAbstract: Claudin-14 (CLDN14), a tight junction protein, contributes to cell proliferation and chemoresistance in human colorectal cancer (CRC)-derived DLD-1 cells. However, small molecules targeting CLDN14 remain unexplored. Here, we identified mupirocin (MUP), a clinically approved topical antibiotic, as a modulator of CLDN14 protein expression. Quartz crystal microbalance analysis revealed interaction between MUP and recombinant CLDN14 protein with a dissociation constant (Kd) of 2.59\u00a0\u00b1\u00a00.54\u00a0\u03bcM. MUP did not alter CLDN14 mRNA levels but reduced CLDN14 protein stability. Pharmacological inhibition of clathrin-mediated endocytosis and lysosomal degradation significantly reversed the MUP-induced reduction of CLDN14 protein. These results suggest MUP accelerates endocytosis-lysosomal degradation of CLDN14 protein. Other antibiotics failed to decrease CLDN14 expression. Functionally, MUP increased paracellular permeability to mineral ions and enhanced the transepithelial flux of doxorubicin (DXR), an anthracycline anticancer drug, and lucifer yellow, an aqueous small compound. In DLD-1 spheroids, MUP reduced intracellular oxidative stress and nuclear factor erythroid 2-related factor 2 (Nrf2) expression. Consequently, MUP promoted intracellular accumulation of DXR and significantly potentiated its cytotoxic effects in spheroids. Moreover, MUP enhanced the antitumor efficacy of other chemotherapeutic agent oxaliplatin. Sulforaphane, an Nrf2 activator, attenuated the MUP-induced enhancement of anticancer efficacy. These findings suggest that MUP enhances anticancer drug sensitivity in CRC through lysosome-dependent downregulation of CLDN14 protein and suppression of oxidative stress signaling.",

Oral LRP was associated with improved fatigue-related behavioral performance, reduced neuronal injury, and better cognitive and motor outcomes. These changes coincided with an increased abundance of putative butyrate-producing bacteria and higher butyrate levels in serum and brain. To examine a possible downstream link, sodium butyrate was tested in cultured microglia and attenuated inflammatory activation while improving mitochondrial stress and autophagy-related readouts. Overall, the data suggest that microbiota-associated butyrate changes may contribute to the observed benefits of LRP, supporting its potential as a food-derived strategy for fatigue-related neuroinflammation.",

This review aim of the synthesize mechanistic evidence on \u03b2-sitosterol as a multi-target phytochemical and clarify how its actions connect to gut-brain axis modulation in neurodegeneration. The integrated mechanistic framework linking \u03b2-sitosterol's effects on cholesterol homeostasis, neuroinflammation, mitochondrial function, cholinergic signaling, and microbiota-barrier integrity to cognitive outcomes. Scope: preclinical and early translational evidence on \u03b2-sitosterol alone and with complementary phytochemicals, including nano-delivery strategies. Increasing evidence highlights phytochemicals as promising multi-target therapeutic agents capable of modulating these interconnected pathological processes. \u03b2-Sitosterol exhibits broad activity by regulating cholesterol metabolism, suppressing neuroinflammation, restoring redox balance, preserving mitochondrial function, and inhibiting important Alzheimer's diseases targets, including acetylcholinesterase and butyrylcholinesterase. The mechanisms action of \u03b2-sitosterol may (i) dampen microglial activation via TLR4/NF-\u03baB signaling, (ii) activate Nrf2-dependent antioxidant responses (Nrf2/HO-1), (iii) support mitochondrial function and reduce ROS, (iv) stabilize membrane cholesterol and modulate amyloidogenic processing, and (v) inhibit acetylcholinesterase/butyrylcholinesterase to restore cholinergic tone. Complementary showing a neuroprotective effect actions of other phytochemicals such as curcumin, resveratrol, sulforaphane, and sinapic acid further enhance neuroprotection by modulating pathways like Nrf2/HO-1, TLR4/NF-\u03baB, PI3K/Akt, and autophagy. Collectively, preclinical studies demonstrate that diverse botanical extracts significantly improve cognitive performance, reduce amyloid burden, restore cholinergic function, and attenuate neuroinflammation and oxidative damage. Emerging preclinical evidence suggests in rodent models of amyloid pathology, \u03b2-sitosterol (5-50\u202fmg/kg) has been reported to improve memory in behavioral tests and reduce markers of neuroinflammation and oxidative stress; gut-brain effects include microbiota remodeling and enhanced barrier integrity, which correlate with reduced neuroimmune activation. Advances in nano-delivery systems and functional food formulations substantially improve phytochemical stability, bioavailability, and brain targeting. Available evidence is chiefly preclinical; clinical translation will require standardized dosing, pharmacokinetic and blood-brain barrier penetration studies, and randomized trials with microbiome and cognitive endpoints.

Currently, the nutraceutical sulforaphane (SFN) has emerged as a promising candidate for enhancing MERCSs communication and offering protection in various contexts. In this study, we investigated whether SFN preserves MERCSs functionality in cardiomyoblasts subjected to cobalt chloride (CoCl2)-induced chemical hypoxia. We explored cellular events, including oxidative stress, endoplasmic reticulum stress (ERS), and autophagy, which are regulated by MERCSs. Our findings confirmed that in rat cardiomyoblasts H9c2 pretreated with SFN and exposed to CoCl2, mitochondrial-ER associations were maintained, facilitating the formation of autophagolysosomes. This suggest that autophagy is a mechanism through which SFN protects cardiomyoblasts under chemical hypoxia. This study underscores the significance of MERCSs as functional platforms for maintaining cellular homeostasis and highlights their potential as strategic targets for mitigating the harmful effects of hypoxia in cardiomyoblasts.",

This study investigates the neuroprotective potential of Sulforaphane (SFN) in ameliorating ethidium bromide (EBRM)-induced MS-like pathology in Wistar rats. The efficacy of SFN at two doses (SFN1.5 and SFN3) was compared to FDA-approved Nrf2 activator drugs, omaveloxolone (OMV15) and dimethyl fumarate (DIMF50). EBRM administration caused neurobehavioral deficits, demyelination, oxidative stress, axonal degeneration, and inflammation. It disrupted key cellular pathways, including Nrf2/HO-1/SIRT-1, JAK/STAT-3/mTOR, and BACE-1/Gamma-secretase/MAPT, as well as caused neurotransmitter imbalances. SFN3 demonstrated significant improvement in motor function, cognitive performance, neurotransmitter levels antioxidant enzymes and alleviated neuroinflammation by modulating inflammatory cytokines. Molecular analyses showed that SFN3 increased Nrf2/HO-1/SIRT-1 levels while decreased pro-inflammatory and neurodegenerative markers such as STAT-3, mTOR, and BACE-1 levels. Gross pathological, Histopathological, and LFB studies indicated reduced demyelination and liver damage. SFN3 also demonstrated favourable systemic safety compared to OMV15. While DIMF50 showed the highest overall efficacy, SFN3 showed consistent modulation of pathological markers, neuroprotective effects, and safety profile. These findings suggest that SFN3 may have therapeutic potential for further translational research in MS. Future studies should validate its clinical relevance and explore combinatorial therapies with existing MS treatments to enhance therapeutic outcomes.",

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.",

Aim of this review is to update the knowledge of Nrf2 as neuroprotective agent of PD. Activation of Nrf2, a transcription factor that regulates the expression of antioxidant and cytoprotective genes, has emerged as a promising therapeutic strategy for PD. Nrf2 is a master regulator of the cellular antioxidant response and is responsible for activating the expression of genes that encode antioxidant enzymes such as superoxidedismutase, catalase, and glutathione peroxidase. Pharmacological agents such as sulforaphane, curcumin, and resveratrol have been shown to activate Nrf2 and upregulate the expression of antioxidant genes in preclinical PD models. Clinical trials are currently underway to evaluate the efficacy of these pharmacological agents in patients with PD. While the neuroprotective role of Nrf2 in PD holds great promise for the development of novel therapies, there are several challenges and limitations that need to be addressed in order to harness the full potential of this pathway in the clinic. Overcoming these obstacles will require interdisciplinary collaborations, innovative research approaches, and a greater understanding of the complex pathophysiology of PD. By addressing these challenges, we can move closer to developing effective neuroprotective therapies that can slow or stop the progression of PD and improve the quality of life for patients with this devastating disease.",

This study describes and evaluates a curriculum-integrated learning experience linking experimental pharmacology, cell culture and Nrf2-related gene expression analysis in third-year Biotechnology students. A total of 32 students participated in the survey-based evaluation. The activity used A549 cells, sulforaphane as an Nrf2-activating compound and tert-butyl hydroperoxide as a pro-oxidant stimulus. Students followed an integrated workflow combining treatment design, cell culture handling, Nrf2-related gene selection, PCR-based gene expression analysis and scientific writing. Perceived learning was assessed using paired pre-post Likert-scale items and analyzed with the Wilcoxon matched-pairs signed-rank test. Post-intervention perceptions, satisfaction and open-ended feedback were analyzed descriptively. Students showed significant improvements in all five pre-post items assessing perceived confidence or familiarity (p value < 0.0001). The proportion of students showing improvement ranged from 81.3% to 100%. Post-intervention responses indicated positive perceptions of interdisciplinary integration, technical competencies, digital competencies, data interpretation and research/professional development. Overall satisfaction was high, with a mean score of 8.50 \u00b1 1.10 out of 10; 87.5% of students rated the activity with a score of 8 or higher. Qualitative feedback highlighted interdisciplinary integration and global understanding of the experimental workflow as key strengths. This curriculum-integrated learning experience was associated with perceived gains across pharmacological, cellular and molecular components of a biotechnology workflow.

Existing pharmacotherapeutic treatments primarily target inflammatory signaling cascades and have disadvantages because of the side effects of drugs, reduced long-term efficacy, and high cost, necessitating the development of safe and sustainable adjunctive therapies. This review synthesizes mechanistic advances regarding dietary polysaccharides as bioactive agents that may have the capacity to induce remodeling of inflamed gastrointestinal tract in colitis and could be an adjunctive strategy as functional food ingredients due to their various biological activities in the management of colitis. Polysaccharides alleviate colitis through several interconnected pathways. First, they correct the gut dysbiosis by enriching beneficial taxa such as Lactobacillus, Bifidobacterium, and Akkermansia muciniphila. Second, fermentation of polysaccharides produces short-chain fatty acids (SCFAs), particularly butyrate, which serve as the primary energy source for colonocytes. Third, they restore intestinal barrier integrity by upregulating tight junction proteins such as ZO-1, occludin, and claudin, also performing pro-inflammatory cascade inhibition and elimination of oxidative stress via Nrf2/HO-1 activation The relationship between structural properties of polysaccharides based on molecular weight, monosaccharide composition, and biological functions of chemically modified dietary polysaccharides in colitis is studied. Dietary polysaccharides are explored here not as replacements for pharmacotherapy but as potential adjunctive or functional food-based interventions that may complement existing treatments as safe, multitargeted, and cost-effective interventions in prevention or long-term management of colitis and IBD. This review presents dietary polysaccharides function not as passive dietary fibers but as bioactive, multi-targeted, structurally dependent agents capable of restoring intestinal homeostasis, suggesting them as potentially safe, adjunctive interventions.",

This study aimed to investigate how rutin-protein nanoparticles modulate the digestibility of extruded recombinant rice through multi-scale structural characterization, in vitro digestibility analysis, and in vitro fermentation evaluation. Multi-scale structural analysis revealed that rutin was successfully incorporated into the recombinant rice matrix, interacting with starch chains through hydrogen bonding. This interaction promoted the transformation of starch crystallinity from A-type to A-\u2009+\u2009V-type. Additionally, the short-range order and the content of single and double helices increased. In vitro digestion experiments demonstrated that the bioaccessibility of rutin in the recombinant rice reached 92.49% after co-extrusion with rutin nanoparticles. The resistant starch content was significantly increased, while C\u221e (final digestion extent) and eGI (estimated glycemic index) value were significantly reduced. Moreover, in vitro fermentation results indicated that the recombinant rice with rutin nanoparticles contributed to reducing gas production and increasing the yields of propionate and butyrate. Rutin nanoparticles modulate starch digestibility through a dual mechanism involving the modification of starch structural domains and rutin bioaccessibility. This study provides a novel strategy and technical support for the development of low-glycemic-index functional staple foods. \u00a9 2026 Society of Chemical Industry.",

The mining of uranium and use of DU in modern weapons underly human exposure that disproportionally impacts military and tribal communities in the United States. Uranium's radiotoxic characteristics are understood, but its chemical hazards much less so. In zebrafish ( Danio rerio ) and human cell cultures we test the hypothesis that exposure to DU negatively impacts cellular function and development through disruption of mitochondrial metabolism. Using a novel shrapnel model with TEM/SEM+EDS, we showed uranium microparticles caused proximity-dependent mitochondrial disruption. In waterborne exposure paradigms, larval movement was reduced and hatching delayed as a result of reduced movement and not enzyme deficiencies in response to 18 ppb DU, below the MCL. Increased DNA damage accumulation was detected in exposed larva and cells. DNA-damage quantitative PCR of DU-exposed larvae showed increased damage in the ahr1 locus (nuclear gene) and decreased mitochondrial DNA (mtDNA) copy number, but mtDNA damage levels varied across experiments. Mitochondrial function was assessed using a resazurin-based assay in the presence and absence of antioxidants and showed diminished cytoplasmic reductive capacity. DU exposure alone did not enrich antioxidant gene expression, contrasting with arsenic exposure, a known ROS-inducer and Nrf2-activator. Sulforaphane (SFN), a potent Nrf2-activator, did not blunt the effects of DU exposure, despite activation of antioxidant response element (ARE) genes ( gstp and gss) , but did blunt the effects of arsenic exposure. The most enriched transcript in DU-exposed larvae coded for slingshot protein phosphatase ( ssh ), further exploration revealed ssh1b as the zebrafish-specific ortholog activated in response to DU, and inhibition using an identified SSH1 inhibitor, Sennoside A, partially rescued the metabolic and hatching defects observed. Our data points to a cytotoxic mechanism in which DU disrupts mitochondrial function through ssh1b enrichment that impairs normal mitophagy, leading to decreased cellular reductive potential independent of either ROS production or ARE-activation. Our results suggest that health impacts from DU exposure may be directly linked to impaired mitochondrial functions.",

Epigenetic dysregulation, involving aberrant DNA methylation, altered histone modifications, dysregulated non-coding RNAs, and N\u2076-methyladenosine (m\u2076A) RNA remodelling, contributes to these processes. Direct evidence that natural compounds modulate m\u2076A machinery in gynaecological cancers remains absent and is considered a knowledge gap. We synthesised evidence on epigenetic alterations in gynaecological cancers and critically evaluated dietary and plant-derived compounds as candidate epigenetic modulators, focusing on preclinical mechanistic studies, pharmacokinetic data, selected early-phase clinical studies, and computational approaches to compound discovery and biomarker stratification. Natural agents, including curcumin, epigallocatechin-3-gallate, sulforaphane, berberine, resveratrol, genistein, diindolylmethane, quercetin, capsaicin, and butyrate, have been reported, mainly in preclinical models, to modulate DNA methyltransferases, histone deacetylases, microRNA networks, tumour suppressor gene expression, and chemosensitivity. However, translation is limited by poor bioavailability, pharmacokinetic variability, insufficient tumour-tissue target-engagement data, weak potency compared with approved epigenetic drugs, limited patient-derived model validation, and a lack of biomarker-driven trials. Compound-specific evidence remains uneven, with stronger support for selected chemosensitising mechanisms than for direct clinical epigenetic efficacy. Natural compounds are mechanistically plausible but clinically under-validated adjunctive epigenetic modulators. Future development requires standardised formulations, improved delivery systems, tumour-tissue pharmacodynamic validation, multi-omics profiling, patient stratification, and biomarker-guided clinical trials to define their realistic role in precision gynaecological oncology. The proposed translational framework may support rational prioritisation of candidates for future preclinical and clinical testing.",

Here, we examined the effects of two haloacetamides, 2,2-dichloroacetamide (DCAcAm) and 2,2-dibromoacetamide (DBAcAm), on mouse oocyte maturation and identified the underlying mechanisms of toxicity. Both compounds markedly impaired meiotic spindle assembly and compromised the function of multiple organelles, including mitochondria, the endoplasmic reticulum, and the Golgi apparatus, primarily through autophagy dysregulation at specific exposure concentrations, as evidenced by the observation that more than half of the oocytes failed to progress beyond the MII stage. Spermidine supplementation effectively restored autophagic activity and rescued the associated cellular defects, thereby improving both nuclear and cytoplasmic maturation in oocytes. Collectively, these findings demonstrate that spermidine alleviates toxicant-induced deterioration of oocyte quality by regulating autophagy and highlight its potential therapeutic value for reproductive protection and clinical application.",

This study investigated whether sheep-derived probiotics could mitigate weaning-associated hepatic injury through the gut-liver axis. Microbiota profiling of six intestinal segments from healthy Hu sheep led to the isolation of nine lactic acid bacterial strains. After in vitro screening for antimicrobial and antioxidant activities, Lactiplantibacillus plantarum M1 and Limosilactobacillus reuteri K4 were selected and administered daily to early-weaned lambs from birth to day 30. Probiotic supplementation partially restored relative organ weights, alleviated hepatic histopathological damage, and reduced biochemical markers of liver injury. It also modulated the colonic mucosal microbiota, enhanced intestinal barrier integrity, and increased colonic acetate and butyrate levels. Liver metabolomics revealed enrichment of the pentose phosphate pathway and glutathione metabolism, accompanied by increased hepatic spermidine abundance and activation of the Nrf2-Keap1 antioxidant pathway. Cell-based validation further showed that spermidine attenuated oxidative stress, at least in part, through modulation of Nrf2-Keap1 signaling. Together, these findings suggest that sheep-derived probiotics may alleviate weaning-induced liver injury in lambs through coordinated microbial, metabolic, and antioxidant regulation along the gut-liver axis.",

Currently, there are no specific medications available for ASD. Increasing attention is now focused on bioactive compounds with anti-inflammatory and antioxidant properties. Sulforaphane (SFN), a key member of the isothiocyanate family, is abundant in cruciferous vegetables. It exhibits potent antioxidant and anti-inflammatory effects with minimal side effects, while oxidative stress and inflammation are recognized triggers in ASD pathogenesis. As research deepens, SFN's physiological activities\u2500including antioxidant, neuroprotective, and anti-inflammatory properties are gaining heightened attention. Building on prior studies, this review comprehensively summarizes seven potential pathways through which SFN protects neurodevelopment or reverses ASD-related neural damage, including Keap1/Nrf2/ARE; MAPKs; NF-\u03baB; HSR; AhR/CYP1; Sirtuin-FOXO; and mTOR/autophagy signaling pathways, elucidating the potential mechanisms underlying its multifaceted actions.

Ferroptosis and mitochondrial biogenesis indicators were measured at various time points following MCAO. Various methods, including transmission electron microscopy, immunofluorescence assay, enzyme-linked immunosorbent assay, Western blotting assays, and real-time quantitative reverse transcription polymerase chain reaction (RT-qPCR), were employed to evaluate the impact of NTF on mitochondrial biogenesis and ferroptosis in vivo and in vitro. IS significantly inhibits mitochondrial biogenesis and increases neuronal ferroptosis, with brain damage worsening over time. MCAO groups showed reduced expression of Nrf2, TFAM, ATP, CISD2, FPN, GPX4, SOD, and HO-1, alongside elevated Fe\u00b2\u207a, ROS, and LPO (P < 0.05) compared to the control group. Both sulforaphane and NTF treatment reversed these effects; NTF treatment effectively increased the expression of Nrf2, TFAM, FtMt, CISD1, CISD2, FPN, and GPX4 while inhibiting the levels of Fe2+, ROS, and LPO. (P < 0.05). This finding clarifies mitochondrial biogenesis's crucial role, proposes a new \"pathway + molecule\" strategy for IS treatment, and supports NTF's clinical potential, though larger animal models and long-term safety studies are needed. In the context of IS, reduced mitochondrial biogenesis plays an important role in ferroptosis. Targeting the Nrf2/TFAM signaling pathway may improve mitochondrial biogenesis in IS. Furthermore, NTF can mitigate ferroptosis by promoting mitochondrial biogenesis through the Nrf2/TFAM signaling pathway.",

This study explores the interplay of endoplasmic reticulum stress (ERS), autophagy, and apoptosis in Cd-induced hepatotoxicity, focusing on whether ERS-driven autophagy protects against liver injury. Male SD rats (4\u202fweeks old, n\u202f=\u202f24) were acclimatized for 7\u202fdays and randomized into four groups receiving CdCl\u2082 at doses of 0, 0.5, 1, or 2\u202fmg/kg for 14 consecutive days. A second cohort (n\u202f=\u202f36) was similarly allocated to six groups: control, Cd, 4-PBA, Cd\u202f+\u202f4-PBA, CQ and Cd\u202f+\u202fCQ. All treatments were administered via daily intraperitoneal injection throughout the study. On day 14, blood and liver tissues were collected for analyses of liver function, hematological parameters, and histopathology. The expression of target factors was analyzed via qRT-PCR and Western blotting. Results indicate that Cd exposure causes liver injury and disordered hepatocyte morphology. ERS markers Grp78 and Caspase-12 and autophagy-related factors Beclin-1, Atg5, P62 and LC3 are upregulated at both mRNA and protein levels. The endoplasmic reticulum-phagy (ER-phagy) receptor FAM134B and the apoptosis effector cleaved Caspase3 are upregulated at the protein level. These findings indicate that Cd induces ERS, UPR activation, autophagy, reticulophagy, and apoptosis. The ERS inhibitor 4-PBA markedly attenuated Cd-induced hepatic injury. Compared with the Cd group, the Cd\u202f+\u202f4-PBA group showed decreased serum ALT and AST levels, as well as reduced RBC, WBC, MCH, and MCV counts. At the molecular level, mRNA and protein expression of ER stress markers Grp78, Caspase-12, PERK, eIF2\u03b1, ATF4, IRE1\u03b1, JNK, and ATF6 were all downregulated. Protein levels of the ER-phagy receptor FAM134B and the apoptosis effector cleaved Caspase-3 were also decreased. The autophagy inhibitor CQ aggravated such injury. Compared with the Cd group, the Cd\u202f+\u202fCQ group showed increased serum ALT and AST levels, as well as elevated RBC, MCH, and MCV counts. At the protein level, expression of the autophagy-related factors P62 and LC3, and the apoptosis effector cleaved Caspase-3 was significantly increased. These results show that Cd-induced ERS activates autophagy and reticulophagy mainly via the PERK, IRE1\u03b1, and ATF6 pathways, and this adaptive response clears autophagic substrates to alleviate hepatocyte damage.",
"42494618": "ID: 42494618\nTitle: Mechanism of Action and Therapeutic Potential of Sulforaphane in Skeletal Muscle Diseases: Molecular Pathways and Precision Medicine.\nAbstract: Sulforaphane (SFN), a bioactive isothiocyanate abundant in cruciferous vegetables, has attracted growing interest as a potential nutraceutical intervention for skeletal muscle disorders. This narrative review synthesizes preclinical and early clinical evidence on the mechanisms and therapeutic applicability of SFN in ICU-acquired weakness, diabetic myopathy, sarcopenia, and exercise-induced muscle damage. SFN modulates skeletal muscle pathophysiology through four interconnected axes: regulation of protein homeostasis via mTOR-associated signaling and suppression of ubiquitin-proteasome-mediated catabolism; upregulation of oxidative stress defenses through Nrf2-driven antioxidant enzyme induction; attenuation of inflammatory networks via NF-\u03baB inhibition and promotion of M2 macrophage polarization; and metabolic reprogramming through AMPK-mediated mitochondrial biogenesis and enhanced insulin sensitivity. Preclinical data suggest preliminary protective effects on respiratory and locomotor muscle; however, clinical translation remains uncertain. Several randomized controlled trials have failed to demonstrate significant effects on Nrf2 target genes or metabolic stress biomarkers, and bioavailability varies markedly across formulations and individuals. Heterogeneous responses across muscle fiber types, an undefined therapeutic window, and interindividual variability in gut microbiota-mediated conversion further complicate clinical application. To address these challenges, we propose a conceptual \"Sulforaphane Precision Medicine Framework\" integrating molecular biomarkers, gut microbiome profiling, and dynamic delivery systems to guide personalized intervention. While SFN shows promise as an adjunctive therapy, standardized formulations, refined patient stratification, and rigorous phase III trials are essential before routine clinical adoption can be recommended.",

Although PFOS exposure causes significant bioaccumulation and potential myelotoxicity, its specific impact on the chondrogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) remains to be elucidated. In this study, we established a murine model of PFOS exposure to isolate primary BMSCs and investigated this issue through in vitro differentiation assays, cellular senescence evaluations, and an in vivo subcutaneous implantation model using gelatin methacryloyl (GelMA) hydrogel scaffolds. Our results demonstrated that PFOS exposure triggered intracellular reactive oxygen species (ROS) accumulation and induced a senescent phenotype in BMSCs, characterized by restricted cellular proliferation and the release of senescence-associated secretory phenotype (SASP) factors, thereby markedly suppressing their chondrogenic capacity. Mechanistically, the inhibition of the Nrf2 signaling pathway by PFOS was identified as the principal driver of this process. Furthermore, both in vitro and in vivo assays confirmed that pharmacological activation using the Nrf2 agonist sulforaphane (SFN) effectively mitigated the senescent phenotype and restored the chondrogenic potential of PFOS-exposed BMSCs. Altogether, these findings elucidate the specific mechanisms of PFOS-induced stem cell toxicity and offer a potential strategy to overcome the resulting limitations in BMSC-based cartilage regeneration.",
"42525741": "ID: 42525741\nTitle: Astrocyte redox imbalance underlies prelimbic neuronal hypoactivity and maladaptive affective behaviors in epilepsy.\nAbstract: A fundamental but unanswered question in neuropsychiatry is whether the psychiatric symptoms of epilepsy are caused by the same or a separate pathophysiology as seizures. To address this question, we investigated a monogenic form of epilepsy (pyridoxine-dependent epilepsy) caused by aldehyde dehydrogenase 7 family member A1 (ALDH7A1) mutations. ALDH7A1 global knockout mice exhibited both seizure-associated and maladaptive affective behavioral phenotypes. However, seizure phenotypes were caused by ALDH7A1 deletion in hepatocytes whereas maladaptive affective behaviors were caused by ALDH7A1 deletion in astrocytes. Deletion in astrocytes disrupted astrocyte redox homeostasis, impairing regulation of extracellular ion concentrations and reducing neuronal activity in the prelimbic cortex. Sulforaphane, which activates the NRF2 antioxidant pathway, restored prelimbic neuronal activity and rescued maladaptive affective behaviors in ALDH7A1 knockout mice but did not prevent seizures. These studies implicate astrocyte redox homeostasis and prelimbic hypoactivity in maladaptive affective behavioral phenotypes in a congenital form of epilepsy, which are mechanistically and therapeutically dissociable from seizure pathophysiology.",
"42530545": "ID: 42530545\nTitle: Genetic and pharmacologic modulations elucidate NRF2 protective role in acute pancreatitis.\nAbstract: Acute pancreatitis (AP) is a potentially fatal disease of the exocrine pancreas. The disease pathogenesis remains obscure, and no effective treatment is available. Uncontrolled, deregulated inflammation is a major cause of systemic complications in AP; however, approaches to reduce inflammation in human disease by inhibiting inflammatory mediators encountered multiple challenges and have not been successful. Oxidative stress drives inflammation in many diseases but its role in AP remains poorly understood. This study evaluates the role of NRF2, the master antioxidant defense transcription factor, in the inflammatory response and severity of experimental AP in mouse and cellular (ex vivo) models. Pancreas-specific genetic ablation of NRF2 worsened nonalcoholic and alcohol-mediated AP by downregulating antioxidant gene expression and upregulating inflammatory mediators, as shown by RNA-seq analysis. Pancreatic NRF2 was activated in the experimental AP models; however, this activation was insufficient to prevent oxidative stress and inflammation. Additional pharmacologic NRF2 activation with sulforaphane markedly reduced oxidative stress, inflammation, and other pancreatitis responses; importantly, it ameliorated a recurrent episode of AP. The results highlight a major role of NRF2 in protecting against oxidative stress and inflammation in AP; and suggest pharmacologic activation of NRF2 as a promising therapeutic strategy to mitigate inflammation and reduce the severity of pancreatitis.",

The polyamine spermidine was suggested to exert neuroprotective effects, but its concentration-dependent impact on longevity, neuronal integrity, and behavior remains still not well studied. Here, we investigated the effects of spermidine on lifespan, behavioral responses, brain tissue, target gene expression, and antioxidant status in Drosophila melanogaster model of age-dependent neurodegeneration. Wild-type flies and swiss cheese (sws1) mutants were exposed to 0.5, 1, and 5\u2009mM spermidine from early adulthood. Lifespan analysis revealed that high-dose spermidine (5\u2009mM) reduced survival in both wild-type and sws1 mutants, whereas lower doses (0.5 and 1\u2009mM) significantly improved survival in mutants without affecting wild-type flies. Behavioral assays revealed that sws1 flies exhibited reduced climbing ability compared to controls, which was further decreased at 5\u2009mM. Lower concentrations did not significantly affect locomotor performance. Taste preference for trehalose, impaired in untreated sws1 mutants, was partially restored by spermidine at all tested concentrations. Histological analysis of 10-13-day-old mutants showed a concentration-dependent reduction in degeneration zones within the lamina and medulla at 0.5 and 1\u2009mM, whereas 5\u2009mM had no effect. Biochemical assays indicated mild pro-oxidant effects at 5\u2009mM, reflected by increased malondialdehyde (MDA) levels, while 0.5\u2009mM enhanced antioxidant defenses, including catalase activity and Trolox equivalent antioxidant capacity (TEAC). Our results suggest that spermidine at low doses has the potential to be a general-purpose neuroprotector.",

Under homeostatic conditions, Keap1 targets Nrf2 for ubiquitination and proteasomal degradation. When Keap1 is inactivated by electrophiles or Keap1-Nrf2 protein-protein interaction (PPI) inhibitors (termed inducers), Nrf2 accumulates and, in association with a small musculoaponeurotic fibrosarcoma (sMaf) protein, induces the transcription of networks of genes encoding cytoprotective proteins. To understand the PPIs between Nrf2 and Keap1 and the effect of inducers in the cellular context, we expressed GFP-Nrf2 and Keap1-mCherry fusion proteins and employed F\u00f6rster resonance energy transfer (FRET)-based multiphoton fluorescence lifetime imaging microscopy (FLIM). PPI inhibitors, but not electrophiles, caused dissociation of GFP-Nrf2 from Keap1-mCherry. To monitor the protein stability of Nrf2, we developed a genetically encoded FLIM-timer-tagged Nrf2, which combines sfGFP and mCherry connected by a linker positioning the fluorophores in a way that promotes FRET. In cells co-expressing stoichiometric amounts of FLIM-timer-Nrf2 with Keap1 from a single promoter, the addition of sulforaphane, the classical Keap1-targeting electrophile, decreased the fluorescence lifetime of the Nrf2-FLIM-timer, consistent with Nrf2 stabilization. Such decrease was also observed upon depletion of either the N-terminal Keap1-binding motif of Nrf2, or a degron within its Neh6 domain that confers \u03b2-TrCP-dependent degradation. These findings show the utility of FRET/FLIM-based bioassays for monitoring Nrf2 activation and illustrate their potential for exploring various aspects of the oxidative stress response.",

To our knowledge, no prior systematic review has synthesized evidence linking these metabolites to direct mitochondrial endpoints across all major metabolite classes. PubMed, Scopus, and Web of Science were systematically searched through March 2026 for studies examining direct mitochondrial endpoints in relation to ten classes of gut-derived metabolites. Gut-derived microbial metabolites exert diverse effects on mitochondrial function, ranging from bioenergetic enhancement to direct toxicity. After contextual evidence was excluded from the certainty assessment, four metabolite-mitochondrial outcome groupings had moderate certainty: butyrate, propionate, indoxyl sulfate, and lipopolysaccharide. Evidence for p-cresyl sulfate, H\u2082S, and urolithin A was rated low; evidence for the remaining metabolite classes was low or very low. Butyrate generally enhances mitochondrial biogenesis, ATP generation, and electron transport chain activity across multiple experimental models. Indoxyl sulfate generally impaired mitochondrial function, whereas p-cresyl sulfate produced concentration- and model-dependent effects. PGC-1\u03b1 emerges as a central regulatory node, integrating microbial metabolic signals to control mitochondrial biogenesis and oxidative metabolism. Many microbial metabolites demonstrate concentration-dependent biphasic effects. These findings support a mechanistic microbiome-mitochondrial framework in which diverse gut-derived molecules converge on a limited set of mitochondrial control nodes: electron transport chain activity, reactive oxygen species handling, biogenesis, and mitophagy. The evidence base is predominantly preclinical; these insights should be considered hypothesis-generating.",
"42576627": "ID: 42576627\nTitle: Senecavirus a 3C protease cleaves RETREG1 to antagonize ER-phagy and promote viral replication via endoplasmic reticulum calcium signaling.\nAbstract: Co-evolution between viruses and autophagy has led to the emergence of viral strategies that manipulate host endoplasmic reticulum (ER) homeostasis, ultimately promoting viral replication. ER turnover is achieved through selective autophagy, also referred to as ER-phagy, which is regulated by the RETREG1/FAM134B (reticulophagy regulator 1) family of reticulon proteins. Nevertheless, how viruses target RETREG1, a receptor for ER-phagy, remains largely unclear. In this study, we demonstrate that infection with Senecavirus A (SVA), an emerging picornavirus, triggers the cleavage of RETREG1, which functions as a negative regulator of viral replication. By screening viral proteins, we identified the SVA 3C protease (3C[pro]) as the executor of this cleavage event. Detailed mapping revealed that residues Q428, E430, and G431 of RETREG1 are involved in its cleavage by the 3C[pro], and the resulting two fragments fail to suppress viral replication. Furthermore, proteolytic cleavage of RETREG1 by 3C[pro] impairs its ability to relieve ER stress and mediate ITPR1 degradation via RETREG1-dependent ER-phagy. This disruption leads to increased ER calcium (Ca2+) release and subsequent activation of autophagy through the CAMKK2-PRKAA2-MTOR axis, which ultimately facilitates SVA replication. Taken together, these findings indicate that SVA antagonizes the antiviral function of RETREG1-mediated ER-phagy via its 3C[pro], highlighting RETREG1 as a potential therapeutic target for combating SVA infection.Abbreviations: 2-APB: 2-aminoethyl diphenylborinate; PRKAA2/AMPK: protein kinase AMP-activated catalytic subunit alpha 2; ATL3: atlastin GTPase 3; BHK-21: baby hamster kidney-21; CAMKK2: calcium/calmodulin dependent proteinkinase kinase2; CCPG1: cell cycle progression 1; CKAP4/CLIMP63: cytoskeleton associated protein 4; co-IP: co-immunoprecipitation; CQ: chloroquine; DAPI: 4',6-diamidino-2-phenylindole; DM: double mutant; EIF2AK3/PERK: eukaryotic translation initiation factor 2 alpha kinase 3; eGFP: enhanced green fluorescent protein; ER: endoplasmic reticulum; GFP: green fluorescent protein; HSPA5/GRP78/BiP: heat shock protein family A (Hsp70) member 5; HA: hemagglutinin; HDAC4: histone deacetylase 4; HEK-293T: human embryonic kidney 293T; hpi: hours post-infection; IFA: indirect immunofluorescence assay; ITPR1/IP3R1: inositol 1,4,5-trisphosphate receptor type 1; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; LIR: LC3-interacting region; mCherry: monomeric cherry; MTOR: mechanistic target of rapamycin kinase; REEP5: receptor accessory protein 5; RETREG1/FAM134B: reticulophagy regulator 1; RTN3: reticulon 3; SD: standard deviation; SEC61B: SEC61 translocon subunit beta; SEC62: SEC62 preprotein translocation factor; SERP1/RAMP4: stress associated endoplasmic reticulum protein 1; siRNA: small interfering RNA; SQSTM1/p62: sequestosome 1; ST: swine testis; SVA: Senecavirus A; TEM: transmission electron microscopy; TEX264: testis expressed 264, ER-phagy receptor; Tm: tunicamycin; U2OS: human osteosarcoma epithelial cells; UV: ultraviolet; ZVAD-FMK: benzyloxycarbonyl-Val-Ala-Asp(OMe)-fluoromethylketone; \u03bcg: microgram; \u03bcm: micrometer; \u03bcM: micromole.",

Here, we reveal a gut microbiota-dependent mechanism underlying its therapeutic efficacy against chronic intestinal inflammation. Using a DSS-induced mouse model and antibiotic-mediated microbiota depletion, we demonstrate that asiaticoside requires microbial metabolism to alleviate epithelial injury, oxidative stress, and inflammatory cytokine production. HPLC analysis showed that asiaticoside is hydrolyzed by gut microbes into asiatic acid, which accumulates in colonic tissues and suppresses IL-17 signaling, NF-\u03baB, and JAK2/STAT3 activation while restoring Nrf2-mediated antioxidant responses. The released glycosides are further fermented into butyrate and other short-chain fatty acids, supporting colonocyte metabolism and intestinal barrier function. Antibiotic treatment abolishes asiaticoside conversion, SCFA production, and therapeutic efficacy. These findings establish microbial biotransformation as a critical determinant of asiaticoside activity and a key mechanism governing natural glycoside pharmacology.",

This narrative review examines four mechanistically distinct compounds, namely spermidine, fisetin, berberine, and urolithin A, as emerging functional food ingredients with scientifically supported effects on key hallmarks of human aging. Spermidine, a dietary polyamine from wheat germ and fermented foods, induces autophagy through EP300 inhibition and is associated with reduced all-cause mortality in prospective studies. Fisetin, a flavonoid from strawberries and apples, exerts senolytic activity by selectively eliminating senescent cells via PI3K/AKT and Bcl-2/Bcl-xL inhibition, with emerging clinical evidence. Berberine, an isoquinoline alkaloid from Berberis species, modulates metabolic dysfunction via AMP-activated protein kinase (AMPK) activation and reshapes gut microbiota composition through direct high intraluminal exposure, with the most extensive clinical dataset of the four compounds. Urolithin A, a gut microbiome-derived postbiotic from ellagitannins in pomegranates and nuts, induces mitophagy via PINK1/Parkin and has been evaluated in a growing number of registered human clinical trials. Together, the four compounds primarily target distinct but complementary aging-associated pathways (autophagy, senolysis, metabolic regulation, mitophagy), suggesting rational potential for combined functional food formulations.

This pathway involves two key proteins: Nuclear factor erythroid 2-related factor 2 (Nrf2), a crucial regulator of cellular defenses, and Kelch ECH associating protein 1 (Keap1), a repressor protein. Keap1 interacted with Nrf2, leading to the degradation of Nrf2 via the ubiquitin-proteasome pathway. In this study, we cloned these proteins from Meretrix meretrix, obtaining full-length cDNA sequences of 2172\u202fbp and 1791\u202fbp. Sequence alignment and phylogenetic analysis revealed that Nrf2 and Keap1 were highly conserved among Molluscan species, yet distinct in M. meretrix. MmNrf2 and MmKeap1 were expressed in multiple tissues, with the highest expression levels in the digestive gland and gill, respectively. We conducted RNA interference experiments to analyze the mRNA transcription profiles of key genes in the Keap1-Nrf2 signaling pathway (Nrf2, Keap1, Maf, p62), xenobiotic metabolism genes (CYP3A3 and Pgp), and antioxidant and detoxification genes (SOD, NQO1, CAT, and GCLM). We also measured ROS, T-AOC, malondialdehyde (MDA), and GSH levels in the digestive gland after exposure to 10\u202f\u03bcg/L benzo[a]pyrene (BaP) for 6\u202fh. Results showed a 60.95% decrease in MmNrf2 mRNA levels. Changes in the Keap1-Nrf2 signaling pathway and BaP-induced oxidative stress gene expression aligned with MmNrf2, suggesting its important role in activating antioxidant and detoxification genes. Additionally, ROS, T-AOC, and GSH levels in the digestive gland significantly increased after 10\u202f\u03bcg/L BaP exposure but decreased 6\u202fh post-siNrf2 injection. We also evaluated the effects of 10\u202f\u03bcM Sulforaphane on the Keap1-Nrf2 signaling pathway and BaP-induced oxidative stress indicators in M. meretrix using real-time PCR after 24\u202fh of exposure to 1\u202f\u03bcg/L BaP. The combined exposure to 10\u202f\u03bcM SFN and 1\u202f\u03bcg/L BaP led to decreased ROS levels compared with BaP single treatment, while T-AOC and GSH levels increased significantly; all genes showed induced expression after 24\u202fh, though slightly decreased after adding 10\u202f\u03bcM SFN. In conclusion, our data imply that MmNrf2 responds to oxidative stress factors, regulated the Keap1-Nrf2 signaling pathway, and played a crucial role in modulating antioxidant enzyme gene expression in bivalve mollusks.",
"42607684": "ID: 42607684\nTitle: ER-liquid condensate contacts sequester FAM134B/C and RhoA to govern cell morphology.\nAbstract: Endoplasmic reticulum (ER)-phagy receptors have elusive physiological functions beyond ER remodeling. To gain insight into these, we screen for cytoplasmic interactors of well-known receptors in mouse pancreatic ductal adenocarcinoma cells. Our data subsequently reveal a non-canonical action of PRKAR1A, a subunit of protein kinase A (PKA), in binding and activating FAM134B/C. At a molecular level, an amphipathic helix in the otherwise-disordered C terminus of FAM134B directly binds PRKAR1A dimers. Multimodal imaging reveals that this interaction occurs at interorganellar contact sites between the ER and liquid-like condensates of PRKAR1A. Mechanistically, ER-condensate contacts promote clustering of FAM134B/C with LC3B and recruit lysosomes, forming degradation hubs. Unexpectedly, these structures are found to control cytoplasmic signaling through FAM134B/C-mediated lysosomal sequestration of RhoA. Underscoring the physiologic relevance of this, these cytoplasmic-facing actions of FAM134B/C result in RhoA-dependent cell morphologic and migratory control in response to cyclic AMP (cAMP) stimuli. Thus, interorganellar contacts expand the roles of FAM134B/C ER-phagy receptors beyond ER degradation.",
"42610256": "ID: 42610256\nTitle: Gut Microbiota-Derived Butyrate Strengthens Blood-Brain Barrier Integrity and Attenuates Streptococcus suis SC19-Induced Meningitis: Involvement of the Gut-Brain Axis.\nAbstract: Streptococcus suis serotype 2 (SS2) is a major zoonotic pathogen that causes severe meningitis and high mortality in both humans and swine. Growing evidence shows that metabolites generated along the gut-brain axis regulate neuroinflammation. In this study, we demonstrate that oral administration of sodium butyrate (NaB) (300 or 600\u2009mg/kg/day) for 28 days lowered mortality and lessened neuropathological signs in mice infected with SS2 (SC19 strain). Butyrate prophylaxis was associated with lower bacterial loads in the blood and brain tissue, preserved expression of tight junction proteins (ZO-1, Claudin-5, and Occludin) in the brain, and maintained blood-brain barrier (BBB) integrity and permeability. 16S rRNA sequencing analysis revealed that SC19 infection significantly diminished the diversity and richness of the gut microbiota, notably depleting key short-chain fatty acid (SCFA)-producing bacterial taxa. Butyrate intervention restored microbial homeostasis and enriched SCFA-producing communities. Mechanistically, butyrate was associated with upregulated expression of nuclear factor erythroid 2-related factor 2 (Nrf2) and its downstream antioxidant effectors (heme oxygenase 1 [HO-1] and NQO1), while inhibiting phosphorylation of NF-\u03baB p65 and the secretion of proinflammatory cytokines (interleukin-1\u03b2 [IL-1\u03b2], interleukin-6 [IL-6], and tumor necrosis factor-\u03b1 [TNF-\u03b1]) in human cortical microvessels endothelial cells/D3 (hCMEC/D3) cells. Critically, these protective effects were abrogated upon pharmacological inhibition of Nrf2, indicating the critical role of Nrf2 in butyrate-mediated attenuation of neuroinflammation and oxidative stress. Our findings highlight the prophylactic potential of modulating the gut-brain axis as a novel strategy to mitigate central nervous system (CNS) infections associated with foodborne pathogens.",
"42617706": "ID: 42617706\nTitle: Exercise and phytochemicals as modulators of redox homeostasis in aging.\nAbstract: Reduced resilience to physiological stress, including impaired redox signaling, is a hallmark of aging that contributes to chronic disease risk. The transcription factor Nrf2 is widely considered a master regulator of redox homeostasis. Although exercise is a potent activator of Nrf2 signaling, exercise-induced Nrf2 activation is attenuated with aging. One emerging strategy to restore or potentiate exercise-induced Nrf2 activation in older adults is to combine exercise with phytochemicals known to modulate Nrf2 activity. This review summarizes redox homeostasis and Nrf2 signaling during exercise and training, how these processes are impacted during aging, and the current evidence for and against combining phytochemicals known to activate Nrf2 signaling (i.e., astaxanthin, curcumin, and sulforaphane) with exercise in older populations. We also highlight mechanistic differences between exercise- and phytochemical-induced Nrf2 activation and consider whether combining these two interventions could enhance redox resilience more than either alone. Despite early signs of promise (largely derived from cell culture and rodent studies), current evidence is insufficient to fully support the benefits of combining phytochemicals with exercise, with limited clinical data in aging populations. Nevertheless, the rationale for further research is compelling, and we outline key translational challenges and priorities for future trials to advance the field forward.",
"42618638": "ID: 42618638\nTitle: Sulforaphane mitigates behavioral deficits in experimental chronic kidney disease through regulation of Nrf2/NLRP3 inflammasome.\nAbstract: Depression is one of the most prevalent psychiatric disorders among patients with chronic kidney disease (CKD). Growing evidence suggests that oxidative stress and inflammation contribute to the development of CKD-associated depression. Sulforaphane, a natural isothiocyanate with potent antioxidant and anti-inflammatory properties, has demonstrated promising neuroprotective and antidepressant-like effects. Therefore, this study investigated the effects of sulforaphane on depressive-like behavior in an adenine-induced CKD rat model and explored the underlying mechanisms, using fluoxetine as a reference treatment. Forty adult male Wistar rats were randomly assigned to five equal groups. Group I (control) received the drug vehicle, Group II received an adenine-containing diet (0.25% w/w in feed), Group III received an adenine-containing diet plus oral sulforaphane (5\u00a0mg/kg/day), Group IV received an adenine-containing diet plus oral sulforaphane (0.5\u00a0mg/kg/day), and Group V received an adenine-containing diet plus oral fluoxetine (10\u00a0mg/kg/day). The experimental period lasted for 5\u00a0weeks. Behavioral assessments were conducted during the final week using the sucrose preference, light-dark, and forced swim tests. Following euthanasia, kidney and brain tissues were collected for biochemical and histopathological analyses. Brain oxidative stress markers, including malondialdehyde (MDA), reduced glutathione (GSH), and nuclear factor erythroid 2-related factor 2 (Nrf2), as well as inflammatory markers, including interleukin-1\u03b2 (IL-1\u03b2), tumor necrosis factor-\u03b1 (TNF-\u03b1), and NOD-like receptor protein 3 (NLRP3) inflammasome, were evaluated. Sulforaphane dose-dependently improved renal function, histopathological alterations, behavioral performance, and brain antioxidant and anti-inflammatory status. These beneficial effects may be associated, at least in part, with modulation of the Nrf2/NLRP3 signaling pathway.",
"42620616": "ID: 42620616\nTitle: PRRSV suppresses ER-phagy through Nsp2- and Nsp5-mediated degradation of FAM134B.\nAbstract: Porcine reproductive and respiratory syndrome virus (PRRSV) is a significant pathogen in the swine industry that causes reproductive failure in sows and respiratory distress in pigs of all ages, leading to substantial economic losses globally. PRRSV manipulates host cellular processes, particularly those associated with endoplasmic reticulum (ER) function. ER-phagy plays a crucial role in maintaining ER homeostasis and enabling cellular adaptations to stress. Whether and how PRRSV modulates ER-phagy remains incompletely understood. ER-phagy was monitored by western blotting for free mCherry from the mCherry-Sec61B reporter. FAM134B mRNA and protein levels were examined by RT-qPCR and western blotting, respectively. All 12 PRRSV Nsps were screened for FAM134B-suppressing activity by co-transfection, followed by western blotting. Co-immunoprecipitation (Co-IP) was performed to assess interactions between candidate Nsps and FAM134B, as well as their impact on FAM134B- microtubule-associated proteins light chain 3 (LC3) binding. Viral replication was evaluated by RT-qPCR targeting ORF7 and TCID50 assays. We investigated the interplay between PRRSV and ER-phagy and discovered that PRRSV suppresses ER-phagy during the late stages of infection. Further analysis revealed that PRRSV employs its Nsps to inhibit the expression of FAM134B. Specifically, PRRSV Nsp2 and Nsp5 interact with FAM134B, promote its degradation and disrupt its binding to microtubule-LC3, thereby impairing ER-phagy. Collectively, our findings uncover a novel viral strategy to subvert host ER-phagy and provide new insights into PRRSV pathogenesis."
