We demonstrate that host BAG3 and HSP70 recognize VP40 as a client and inhibit the egress of VP40 virus-like particles (VLPs) by promoting degradation of VP40 via Chaperone-assisted selective autophagy (CASA). Pharmacological inhibition of either the early stage formation of the VP40/BAG3/HSP70 tripartite complex, or late stage formation of autolysosomes, rescued VP40 VLP egress back to WT levels. The mechanistic target of rapamycin complex 1 (mTORC1) is a master regulator of autophagy, and we found that surface expression of EBOV GP on either VLPs or an infectious VSV recombinant virus, activated mTORC1. Notably, pharmacological suppression of mTORC1 signaling by rapamycin activated CASA in a BAG3-dependent manner to restrict the egress of both VLPs and infectious EBOV in Huh7 cells. In sum, our findings highlight the involvement of the mTORC1/CASA axis in regulating filovirus egress."

Reemergence of these filoviruses remains a global public health threat, highlighting the need for novel countermeasures to control and treat future disease outbreaks. The EBOV VP40 matrix protein drives virion assembly and egress. We recently reported that BAG3 and HSPA/HSP70, two central components of chaperone-assisted selective autophagy (CASA), target VP40 for autophagic sequestration and degradation, thereby inhibiting virus egress and spread. In addition, we found that expression of the EBOV glycoprotein (GP) activates MTORC1, the gateway regulator of autophagy. Notably, pharmacological suppression of MTORC1 signaling by rapamycin activates autophagy and blocks filovirus egress. These findings highlight the MTORC1-CASA axis as a regulator of filovirus egress and suggest new opportunities for antiviral development and intervention."

"abstract_text": "ID: 28076420\nTitle: Chaperone-Mediated Autophagy Protein BAG3 Negatively Regulates Ebola and Marburg VP40-Mediated Egress.\nAbstract: Ebola (EBOV) and Marburg (MARV) viruses are members of the Filoviridae family which cause outbreaks of hemorrhagic fever. The filovirus VP40 matrix protein is essential for virus assembly and budding, and its PPxY L-domain motif interacts with WW-domains of specific host proteins, such as Nedd4 and ITCH, to facilitate the late stage of virus-cell separation. To identify additional WW-domain-bearing host proteins that interact with VP40, we used an EBOV PPxY-containing peptide to screen an array of 115 mammalian WW-domain-bearing proteins. Using this unbiased approach, we identified BCL2 Associated Athanogene 3 (BAG3), a member of the BAG family of molecular chaperone proteins, as a specific VP40 PPxY interactor. Here, we demonstrate that the WW-domain of BAG3 interacts with the PPxY motif of both EBOV and MARV VP40 and, unexpectedly, inhibits budding of both eVP40 and mVP40 virus-like particles (VLPs), as well as infectious VSV-EBOV recombinants. BAG3 is a stress induced protein that regulates cellular protein homeostasis and cell survival through chaperone-mediated autophagy (CMA). Interestingly, our results show that BAG3 alters the intracellular localization of VP40 by sequestering VP40 away from the plasma membrane. As BAG3 is the first WW-domain interactor identified that negatively regulates budding of VP40 VLPs and infectious virus, we propose that the chaperone-mediated autophagy function of BAG3 represents a specific host defense strategy to counteract the function of VP40 in promoting efficient egress and spread of virus particles."

"abstract_text": "ID: 38796097\nTitle: Exosome-mediated PROTAC delivery for treatment of RNA viral infections and zoonosis.\nAbstract: The increase in diseases caused by RNA viruses, such as influenza, severe acute respiratory syndrome-coronavirus (SARS-CoV), Middle East respiratory syndrome (MERS), and Ebola, presents a growing global health challenge as well as the threat of zoonosis. Traditional antiviral treatments are often undermined by fast-mutating viruses, drug resistance, and newly emerging pathogens. Here, we explore proteolysis-targeting chimeras (PROTACs), a novel protein degradation machinery that has the potential to reshape the way in which RNA viral infections can be managed. PROTACs excel at specifically degrading pathogenic proteins, offering a targeted and efficient antiviral strategy. We also investigate the potential of exosome-based diagnostic technologies, which harness cell-derived nanovesicles for non-invasive sampling and early viral infection detection. Addressing the challenge of PROTAC delivery, we introduce a groundbreaking strategy utilizing exosomes to deliver PROTACs with improved precision and as a targeted delivery vehicle. Integrating these innovative strategies provides a novel approach to combat RNA zoonotic viral diseases, paving the way for a new era in antiviral therapy."

Nano-sized endosomal vesicles called exosomes have gained considerable attention from researchers due to their role in intracellular communication to regulate the biological activity of target cells through cargo proteins, nucleic acids, and lipids. According to recent studies, exosomes play a vital role in viral diseases including covid-19, with their interaction with the host immune system opening the door to effective antiviral treatments. Utilizing the intrinsic nature of exosomes, it is imperative to elucidate how exosomes exert their effect on the immune system or boost viral infectivity. Exosome biogenesis machinery is hijacked by viruses to initiate replication, spread infection, and evade the immune response. Exosomes, however, also participate in protective mechanisms by triggering the innate immune system. Besides that, exosomes released from the cells can carry a robust amount of information about the diseased state, serving as a potential biomarker for detecting viral diseases. This review describes how exosomes increase virus infectivity, act as immunomodulators, and function as a potential drug delivery carrier and diagnostic biomarker for diseases caused by HIV, Hepatitis, Ebola, and Epstein-Barr viruses. Furthermore, the review analyzes various applications of exosomes within the context of COVID-19, including its management."

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.

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.

EBOV infection is dependent on its structural glycoprotein (GP), but high levels of GP expression also trigger cell rounding, detachment, and downregulation of many surface molecules that is thought to contribute to its high pathogenicity. Thus, EBOV has evolved an RNA editing mechanism to reduce its GP expression and increase its fitness. We now report that the GP expression is also suppressed at the protein level in cells by protein disulfide isomerases (PDIs). Although PDIs promote oxidative protein folding by catalyzing correct disulfide formation in the endoplasmic reticulum (ER), PDIA3/ERp57 adversely triggered the GP misfolding by targeting GP cysteine residues and activated the unfolded protein response (UPR). Abnormally folded GP was targeted by ER-associated protein degradation (ERAD) machinery and, unexpectedly, was degraded via the macroautophagy/autophagy-lysosomal pathway, but not the proteasomal pathway. PDIA3 also decreased the GP expression from other ebolavirus species but increased the GP expression from Marburg virus (MARV), which is consistent with the observation that MARV-GP does not cause cell rounding and detachment, and MARV does not regulate its GP expression via RNA editing during infection. Furthermore, five other PDIs also had a similar inhibitory activity to EBOV-GP. Thus, PDIs negatively regulate ebolavirus glycoprotein expression, which balances the viral life cycle by maximizing their infection but minimizing their cellular effect. We suggest that ebolaviruses hijack the host protein folding and ERAD machinery to increase their fitness via reticulophagy during infection.Abbreviations: 3-MA: 3-methyladenine; 4-PBA: 4-phenylbutyrate; ACTB: \u03b2-actin; ATF: activating transcription factor; ATG: autophagy-related; BafA1: bafilomycin A1; BDBV: Bundibugyo ebolavirus; CALR: calreticulin; CANX: calnexin; CHX: cycloheximide; CMA: chaperone-mediated autophagy; ConA: concanamycin A; CRISPR: clusters of regularly interspaced short palindromic repeats; Cas9: CRISPR-associated protein 9; dsRNA: double-stranded RNA; EBOV: Zaire ebolavirus; EDEM: ER degradation enhancing alpha-mannosidase like protein; EIF2AK3/PERK: eukaryotic translation initiation factor 2 alpha kinase 3; Env: envelope glycoprotein; ER: endoplasmic reticulum; ERAD: ER-associated protein degradation; ERN1/IRE1: endoplasmic reticulum to nucleus signaling 1; GP: glycoprotein; HA: hemagglutinin; HDAC6: histone deacetylase 6; HMM: high-molecular-mass; HIV-1: human immunodeficiency virus type 1; HSPA5/BiP: heat shock protein family A (Hsp70) member 5; IAV: influenza A virus; IP: immunoprecipitation; KIF: kifenesine; Lac: lactacystin; LAMP: lysosomal associated membrane protein; MAN1B1/ERManI: mannosidase alpha class 1B member 1; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; MARV: Marburg virus; MLD: mucin-like domain; NHK/SERPINA1: alpha1-antitrypsin variant null (Hong Kong); NTZ: nitazoxanide; PDI: protein disulfide isomerase; RAVV: Ravn virus; RESTV: Reston ebolavirus; SARS-CoV: severe acute respiratory syndrome coronavirus; SBOV: Sudan ebolavirus; sGP: soluble GP; SQSTM1/p62: sequestosome 1; ssGP: small soluble GP; TAFV: Ta\u00ef Forest ebolavirus; TIZ: tizoxanide; TGN: thapsigargin; TLD: TXN (thioredoxin)-like domain; Ub: ubiquitin; UPR: unfolded protein response; VLP: virus-like particle; VSV: vesicular stomatitis virus; WB: Western blotting; WT: wild-type; XBP1: X-box binding protein 1."

However, there are still no effective antiviral therapies that can completely cure EVD. A comprehensive understanding of virus-host interactions would be beneficial for developing new antiviral agents. Here, we showed that CXCR4-induced macroautophagy/autophagy and was internalized to endosomes by interacting with glycoprotein (GP) on viral particles during EBOV infection; this promoted the EBOV attachment and entry, which was reduced by CXCR4 antagonist and neutralizing antibody. We also found that CXCR4 increased EBOV replication by downregulating cytotoxic GP to promote viral fitness instead of influencing the assembly of viral factory. Mechanistically, excessive EBOV GP could hijack CXCR4 sorting and transporting pathways by their interactions with HGS, one of the key components of the ESCRT machinery; subsequently GP could be carried back to the endoplasmic reticulum by CXCR4, where the E3 ubiquitin ligase RNF185 was recruited to polyubiquitinate GP in a K27- and K63-linked manner. Finally, polyubiquitinated GP was degraded in lysosomes via reticulophagy by interacting with RETREG1 (reticulophagy regulator 1), in an ATG3- and ATG5-dependent manner. Our findings revealed dual roles of CXCR4 in regulation of EBOV life cycle, either acting as an entry factor by interacting with GP on viral particles to facilitate viral entry or targeting excessive GP for reticulophagic degradation, providing new evidence that EBOV hijacked the host vesicular transportation system through efficient virus-host interactions to facilitate viral fitness.Abbreviations: Baf A1: bafilomycin A1; BDBV: Bundibugyo Ebolavirus; CHX: cycloheximide; CXCR4: C-X-C motif chemokine receptor 4; CLEC4M/DC-SIGNR: C type lectin domain family 4 member M; EBOV: Zaire Ebolavirus; EEA1: early endosome antigen 1; ER: endoplasmic reticulum; ERAD: ER-associated degradation; ESCRT: endosomal sorting complex required for transport; EVD: Ebolavirus disease; HAVCR1/TIM-1: hepatitis A virus cellular receptor 1; GP: glycoprotein; HGS: hepatocyte growth factor-regulated tyrosine kinase substrate; HIV: human immunodeficiency virus; IFL: internal fusion loop; ITCH/AIP4: itchy E3 ubiquitin protein ligase; LAMP: lysosomal associated membrane protein; LC-MS/MS: liquid chromatography mass spectrometry; PDIs: protein disulfide isomerases; RBD: receptor binding domain; RESTV: Reston Ebolavirus; RETREG1: reticulophagy regulator 1; RNF185: ring finger protein 185; SQSTM1/p62: sequestosome 1; SUDV: Sudan Ebolavirus; TAFV: Ta\u00ef Forest Ebolavirus; TRIM21: tripartite motif containing 21; trVLPs: transcription- and replication-competent virus-like particles; Ub: ubiquitin."

The proteostasis network in the endoplasmic reticulum (ER) is composed of the calnexin cycle, and the two protein degradation pathways ER-associated protein degradation (ERAD) and ER-to-lysosome-associated degradation (ERLAD/ER-phagy/reticulophagy). Here we show that calnexin and calreticulin trigger Zaire Ebolavirus (EBOV) glycoprotein GP1,2 misfolding. Misfolded EBOV-GP1,2 is targeted by ERAD machinery, but this results in lysosomal instead of proteasomal degradation. Moreover, the ER Ub ligase RNF185, usually associated with ERAD, polyubiquitinates EBOV-GP1,2 on lysine 673 via ubiquitin K27-linkage. Polyubiquinated GP1,2 is subsequently recruited into autophagosomes by the soluble autophagy receptor sequestosome 1 (SQSTM1/p62), in an ATG3- and ATG5-dependent manner. We conclude that EBOV hijacks all three proteostasis mechanisms in the ER to downregulate GP1,2 via polyubiquitination and show that this increases viral fitness.

Microglia, the resident immune cells of the central nervous system, orchestrate responses to ischemic injury and critically influence neurovascular remodeling, axonal reorganization, and functional recovery. Emerging evidence indicates that inflammatory preconditioning can reprogram microglial responses to subsequent insults, yet the exact intracellular signaling pathways mediating this adaptive state remain incompletely defined. Here, we used a chemogenetic approach to selectively activate Gq signaling in microglia employing a microglia-specific DREADD mouse model. This strategy mimics Gq-coupled receptor activation in microglia in the absence of peripheral immune engagement. Pre-ischemic Gq activation significantly reduced infarct sizes at 24\u2009h after experimental stroke in female mice and at 7\u2009days in both sexes. Morphological analyses revealed that Gq-conditioned microglia exhibited increased structural complexity, adopting a highly ramified, spatially compact phenotype and higher CD68 expression, indicating increased phagocytic activity. Transcriptional profiling demonstrated that Gq activation primes autophagy-related defense pathways in microglia, resulting in upregulation of interferon-stimulated genes 7\u2009days after stroke in both sexes. Together, our findings identify Gq signaling as a key modulatory pathway capable of reprogramming microglial phenotype and enhancing stroke recovery. These results highlight the plasticity of microglial signaling networks and support targeted modulation of microglial Gq pathways."

These functions are often described as linear pathways of lipogenesis, lipolysis, fatty acid oxidation and thermogenesis. However, lipid handling in adipocytes is spatially organized by organelle contact sites. The endoplasmic reticulum (ER), lipid droplets (LDs), mitochondria, peroxisomes and lysosomes form dynamic interfaces that determine whether fatty acids are stored safely, mobilized for oxidation, processed into specialized lipid species or redirected toward lipotoxic intermediates. In this review, we synthesize evidence that ER-LD and LD-mitochondria contacts coordinate lipid storage and oxidative use, whereas peroxisome-centred contacts connect lipolysis, very-long-chain and branched-chain fatty acid processing, plasmalogen metabolism and mitochondrial remodelling. We further discuss how autophagy and lysosomal pathways maintain adipocyte quality control by regulating LD turnover, mitophagy and membrane renewal. Finally, we propose that obesity, insulin resistance, ectopic lipid deposition, lipodystrophy and adipose inflammation can be viewed as different manifestations of impaired spatial lipid routing. This framework does not replace classical metabolic models, but provides a mechanistic layer that may help identify contact-site-dependent vulnerabilities in metabolic disease."

Herein, we present near-infrared (NIR)-activated enteric prodrug microparticles, HPMCP@L-UCNPs-ONB-5-FU, which enable spatiotemporally controlled release of 5-FU in the colon. The photocleavable prodrug o-nitrobenzyl-5-fluorouracil (ONB-5-FU) is conjugated to large upconversion nanoparticles (L-UCNPs) and encapsulated within the enteric polymer hydroxypropyl methylcellulose phthalate (HPMCP) to resist gastric degradation. After oral administration, low-power 980 nm excitation yields 800 nm emission for bioimaging, whereas high-power excitation generates strong 365 nm emission that cleaves the ONB linker and locally releases active 5-FU. In vitro studies confirmed light-gated and power-dependent drug release, while cellular and orthotopic CRC studies demonstrated potent tumor inhibition with minimal systemic toxicity. Overall, this work establishes a precise and biocompatible NIR-controlled prodrug activation paradigm for oral chemotherapy of CRC."

In GI malignancies, MDR arises from multilayered and interdependent factors, including insufficient intracellular drug accumulation, altered drug activation and metabolic detoxification, target rewiring and phenotypic plasticity, apoptosis-autophagy-mediated stress adaptation, and extrinsic protection from the tumor microenvironment, cancer stem cells, metastatic niches, and microbiome-associated mechanisms. Biomimetic delivery systems (BDSs), including cell membrane-coated nanocarriers, extracellular vesicles, and living or virus-mediated platforms, provide biological interface functions that may improve drug circulation, tumor recognition, tissue penetration, membrane interaction, and active trafficking. However, their therapeutic value in MDR GI cancers should not be judged merely by improved delivery efficiency, but by whether they address defined resistance bottlenecks and generate evidence of genuine re-sensitization in resistant disease contexts. Current evidence indicates that many BDSs remain at the level of exposure enhancement or mechanism-aligned sensitization, whereas only a limited subset has demonstrated functional restoration of treatment response in established resistant models. This review organizes current BDS strategies according to their dominant mechanistic functions: enhancing drug accumulation and intratumoral delivery, reversing cellular drug resistance, remodeling resistance-supportive tumor microenvironment, targeting cancer stem cells (CSCs) and metastatic niches, and enabling site-directed intervention using living carriers and living therapeutics. By linking GI cancer-focused MDR biology to function-oriented biomimetic design, this review establishes an evidence-based framework for distinguishing delivery enhancement from true MDR reversal and outlines platform-specific requirements for clinical translation."

In this review, the immunotherapy strategies, biomaterials, devices, and diseases supposed to be treated by immunotherapeutic strategies are reviewed. Several transdermal therapeutic methods, including semisolids, skin patches, chemical, and physical skin penetration enhancers, are discussed. MNs are the most frequent devices implemented in transdermal immunotherapy of cancers (e.g., melanoma, squamous cell carcinoma, cervical, and breast cancer), infectious (e.g., COVID-19), allergic and autoimmune disorders (e.g., Duchenne's muscular dystrophy and Pollinosis).

Six databases were electronically searched from inception to January 2025. We included original studies reporting biological findings obtained from skeletal muscle biopsies of adults with critical illness. Bibliometrics, characteristics of the patients/controls, and biological findings were extracted in duplicate. Descriptive statistics of biological findings were performed. Random-effects meta-analyses investigated mean differences (MDs) in myofiber cross-sectional area and protein turnover compared with controls. From 22,035 titles screened, 75 studies (n = 2,023 patients; n = 642 controls) published between 1988 and 2024 were included, with 48 unique patient datasets. Biopsies were mainly collected from vastus lateralis (64 [85%] studies) during the first ICU week (50% of studies) and post-ICU (9%). Biological findings included predominant type II myofiber atrophy with necrosis and structural degeneration, mitochondrial dysfunction, inflammatory/fibrotic changes, and upregulated ubiquitin-proteasome/autophagy pathways. Data from six studies (n = 100 patients; 193 controls) indicated that cross-sectional area was 22% lower in patients with critical illness before (MD, -689 \u00b5m2; 95% CI, -1265 to -113 \u00b5m2; p = 0.02) and after (MD, -775 \u00b5m2; 95% CI, -1512 to -37 \u00b5m2; p = 0.04) ICU discharge.

Protein degradation pathway markers were significantly higher (standardized MD ranging, 0.5-1.7) in data from 11 studies (n = 439 patients; 163 controls).

Recent evidence indicates that protein homeostasis (proteostasis) functions as a crucial molecular link connecting tumor progression, therapeutic resistance, cardiac remodeling, and treatment-related cardiotoxicity. Proteostasis, which encompasses the cellular processes of protein synthesis, folding, quality control, and degradation, dictates tissue adaptation to chronic stress. Notably, the adaptive mechanisms that allow tumor cells to endure proteotoxic stress and resist therapy are often vital for maintaining cardiac structure and function. Thus, tumor control and cardiovascular injury may be divergent outcomes of a common stress-response framework. In this review, we propose proteostasis as a comprehensive framework for understanding the cancer-cardiovascular interface. We analyze how the ubiquitin-proteasome system, autophagy-lysosome pathway, endoplasmic reticulum stress-induced unfolded protein response signaling, and molecular chaperone networks are differentially reconfigured in cancer and cardiac tissues, influencing tumor survival, therapeutic susceptibility, and cardiovascular dysfunction. Additionally, we explore the translational implications of proteostasis dysregulation, including mechanisms of anticancer therapy-induced cardiotoxicity, emerging biomarkers, cardioprotective strategies, and opportunities for precision cardio-oncology. By conceptualizing efficacy and toxicity as interconnected outcomes of shared proteostasis biology, this review establishes a foundation for developing therapies that optimize cancer control while safeguarding cardiovascular health."

Metallic nanoparticles have recently been studied for their potential as anthelmintic agents. This research examined the in vitro anthelmintic activity of copper oxide (CuO-NPs) and zinc oxide nanoparticles (ZnO-NPs) against Dicrocoelium dendriticum. Using adult motility inhibition tests and oxidative stress biomarkers, including glutathione peroxidase , glutathione S-transferase , superoxide dismutase , and malondialdehyde , this study evaluated the effects of CuO-NPs and ZnO-NPs. Flukes were treated with various concentrations of nanoparticles (1.00, 4.00, 8.00, 12.00, and 16.00 ppm) for 24 hr. The CuO-NPs and ZnO-NPs demonstrated concentration- and time-dependent anthelmintic activity.

The nanoparticles induced oxidative stress in the flukes, with decreased superoxide dismutase, glutathione S-transferase, and glutathione peroxidase activities and increased malondialdehyde levels. Based on these findings, CuO-NPs and ZnO-NPs exhibit potential as therapeutic agents for controlling and treating D. dendriticum. However, further studies are necessary to assess their safety and efficacy in vivo for managing parasitic infections."

In this study, affinity tag-purification mass spectrometry was employed to delineate RABV glycoprotein and host protein interactions, and PDIA3/ERP57 was identified as a potential inhibitor of RABV infection. PDIA3 restricted RABV infection with follow mechanisms: PDIA3 mediated the degradation of RABV G protein by targeting lysine 332 via the selective macroautophagy/autophagy pathway; The PDIA3 interactor, AP3B1 (adaptor related protein complex 3 subunit beta 1) was indispensable in PDIA3-triggered selective degradation of the G protein; Furthermore, PDIA3 competitively bound with NCAM1/NCAM (neural cell adhesion molecule 1) to block RABV G, hindering viral entry into host cells. PDIA3 190-199 aa residues bound to the RABV G protein were necessary and sufficient to defend against RABV. These results demonstrated the therapeutic potential of biologics that target PDIA3 or utilize PDIA3 190-199 aa peptide to treat clinical rabies.Abbreviation: aa: amino acids; ANXA2: annexin A2; AP-MS: affinity tag purification-mass spectrometry; AP3B1: adaptor related protein complex 3 subunit beta 1; ATP6V1A: ATPase H+ transporting V1 subunit A; ATP6V1H: ATPase H+ transporting V1 subunit H; BafA1: bafilomycin A1; CHX: cycloheximide; co-IP: co-immunoprecipitation; DDX17: DEAD-box helicase 17; DmERp60: drosophila melanogaster endoplasmic reticulum p60; EBOV: Zaire ebolavirus virus; EV: empty vector; GANAB: glucosidase II alpha subunit; G protein: glycoprotein; GRM2/mGluR2: glutamate metabotropic receptor 2; HsPDIA3: homo sapiens protein disulfide isomerase family A member 3; IAV: influenza virus; ILF2: interleukin enhancer binding factor 2; KO: knockout; MAGT1: magnesium transporter 1; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; MmPDIA3: mus musculus protein disulfide isomerase associated 3; NCAM1/NCAM: neural cell adhesion molecule 1; NGFR/p75NTR: nerve growth factor receptor; NGLY1: N-glycanase 1; OTUD4: OTU deubiquitinase 4; PDI: protein disulfide isomerase; PPIs: protein-protein interactions; RABV: rabies virus; RUVBL2: RuvB like AAA ATPase 2; SCAMP3: secretory carrier membrane protein 3; ScPdi1: Saccharomyces cerevisiae s288c protein disulfide isomerase 1; SLC25A6: solute carrier family 25 member 6; SQSTM1/p62: sequestosome 1; VSV: vesicular stomatitis virus."

We demonstrate that host BAG3 and HSP70 recognize VP40 as a client and inhibit the egress of VP40 virus-like particles (VLPs) by promoting degradation of VP40 via Chaperone-assisted selective autophagy (CASA). Pharmacological inhibition of either the early stage formation of the VP40/BAG3/HSP70 tripartite complex, or late stage formation of autolysosomes, rescued VP40 VLP egress back to WT levels. The mechanistic target of rapamycin complex 1 (mTORC1) is a master regulator of autophagy, and we found that surface expression of EBOV GP on either VLPs or an infectious VSV recombinant virus, activated mTORC1. Notably, pharmacological suppression of mTORC1 signaling by rapamycin activated CASA in a BAG3-dependent manner to restrict the egress of both VLPs and infectious EBOV in Huh7 cells. In sum, our findings highlight the involvement of the mTORC1/CASA axis in regulating filovirus egress."

Reemergence of these filoviruses remains a global public health threat, highlighting the need for novel countermeasures to control and treat future disease outbreaks. The EBOV VP40 matrix protein drives virion assembly and egress. We recently reported that BAG3 and HSPA/HSP70, two central components of chaperone-assisted selective autophagy (CASA), target VP40 for autophagic sequestration and degradation, thereby inhibiting virus egress and spread. In addition, we found that expression of the EBOV glycoprotein (GP) activates MTORC1, the gateway regulator of autophagy.

The filovirus VP40 matrix protein is essential for virus assembly and budding, and its PPxY L-domain motif interacts with WW-domains of specific host proteins, such as Nedd4 and ITCH, to facilitate the late stage of virus-cell separation. To identify additional WW-domain-bearing host proteins that interact with VP40, we used an EBOV PPxY-containing peptide to screen an array of 115 mammalian WW-domain-bearing proteins. Using this unbiased approach, we identified BCL2 Associated Athanogene 3 (BAG3), a member of the BAG family of molecular chaperone proteins, as a specific VP40 PPxY interactor. Here, we demonstrate that the WW-domain of BAG3 interacts with the PPxY motif of both EBOV and MARV VP40 and, unexpectedly, inhibits budding of both eVP40 and mVP40 virus-like particles (VLPs), as well as infectious VSV-EBOV recombinants. BAG3 is a stress induced protein that regulates cellular protein homeostasis and cell survival through chaperone-mediated autophagy (CMA). Interestingly, our results show that BAG3 alters the intracellular localization of VP40 by sequestering VP40 away from the plasma membrane. As BAG3 is the first WW-domain interactor identified that negatively regulates budding of VP40 VLPs and infectious virus, we propose that the chaperone-mediated autophagy function of BAG3 represents a specific host defense strategy to counteract the function of VP40 in promoting efficient egress and spread of virus particles."

Traditional antiviral treatments are often undermined by fast-mutating viruses, drug resistance, and newly emerging pathogens. Here, we explore proteolysis-targeting chimeras (PROTACs), a novel protein degradation machinery that has the potential to reshape the way in which RNA viral infections can be managed. PROTACs excel at specifically degrading pathogenic proteins, offering a targeted and efficient antiviral strategy. We also investigate the potential of exosome-based diagnostic technologies, which harness cell-derived nanovesicles for non-invasive sampling and early viral infection detection. Addressing the challenge of PROTAC delivery, we introduce a groundbreaking strategy utilizing exosomes to deliver PROTACs with improved precision and as a targeted delivery vehicle. Integrating these innovative strategies provides a novel approach to combat RNA zoonotic viral diseases, paving the way for a new era in antiviral therapy."

Nano-sized endosomal vesicles called exosomes have gained considerable attention from researchers due to their role in intracellular communication to regulate the biological activity of target cells through cargo proteins, nucleic acids, and lipids. According to recent studies, exosomes play a vital role in viral diseases including covid-19, with their interaction with the host immune system opening the door to effective antiviral treatments. Utilizing the intrinsic nature of exosomes, it is imperative to elucidate how exosomes exert their effect on the immune system or boost viral infectivity. Exosome biogenesis machinery is hijacked by viruses to initiate replication, spread infection, and evade the immune response. Exosomes, however, also participate in protective mechanisms by triggering the innate immune system. Besides that, exosomes released from the cells can carry a robust amount of information about the diseased state, serving as a potential biomarker for detecting viral diseases. This review describes how exosomes increase virus infectivity, act as immunomodulators, and function as a potential drug delivery carrier and diagnostic biomarker for diseases caused by HIV, Hepatitis, Ebola, and Epstein-Barr viruses. Furthermore, the review analyzes various applications of exosomes within the context of COVID-19, including its management."

EBOV infection is dependent on its structural glycoprotein (GP), but high levels of GP expression also trigger cell rounding, detachment, and downregulation of many surface molecules that is thought to contribute to its high pathogenicity. Thus, EBOV has evolved an RNA editing mechanism to reduce its GP expression and increase its fitness. We now report that the GP expression is also suppressed at the protein level in cells by protein disulfide isomerases (PDIs). Although PDIs promote oxidative protein folding by catalyzing correct disulfide formation in the endoplasmic reticulum (ER), PDIA3/ERp57 adversely triggered the GP misfolding by targeting GP cysteine residues and activated the unfolded protein response (UPR). Abnormally folded GP was targeted by ER-associated protein degradation (ERAD) machinery and, unexpectedly, was degraded via the macroautophagy/autophagy-lysosomal pathway, but not the proteasomal pathway. PDIA3 also decreased the GP expression from other ebolavirus species but increased the GP expression from Marburg virus (MARV), which is consistent with the observation that MARV-GP does not cause cell rounding and detachment, and MARV does not regulate its GP expression via RNA editing during infection. Furthermore, five other PDIs also had a similar inhibitory activity to EBOV-GP. Thus, PDIs negatively regulate ebolavirus glycoprotein expression, which balances the viral life cycle by maximizing their infection but minimizing their cellular effect. We suggest that ebolaviruses hijack the host protein folding and ERAD machinery to increase their fitness via reticulophagy during infection.Abbreviations: 3-MA: 3-methyladenine; 4-PBA: 4-phenylbutyrate; ACTB: \u03b2-actin; ATF: activating transcription factor; ATG: autophagy-related; BafA1: bafilomycin A1; BDBV: Bundibugyo ebolavirus; CALR: calreticulin; CANX: calnexin; CHX: cycloheximide; CMA: chaperone-mediated autophagy; ConA: concanamycin A; CRISPR: clusters of regularly interspaced short palindromic repeats; Cas9: CRISPR-associated protein 9; dsRNA: double-stranded RNA; EBOV: Zaire ebolavirus; EDEM: ER degradation enhancing alpha-mannosidase like protein; EIF2AK3/PERK: eukaryotic translation initiation factor 2 alpha kinase 3; Env: envelope glycoprotein; ER: endoplasmic reticulum; ERAD: ER-associated protein degradation; ERN1/IRE1: endoplasmic reticulum to nucleus signaling 1; GP: glycoprotein; HA: hemagglutinin; HDAC6: histone deacetylase 6; HMM: high-molecular-mass; HIV-1: human immunodeficiency virus type 1; HSPA5/BiP: heat shock protein family A (Hsp70) member 5; IAV: influenza A virus; IP: immunoprecipitation; KIF: kifenesine; Lac: lactacystin; LAMP: lysosomal associated membrane protein; MAN1B1/ERManI: mannosidase alpha class 1B member 1; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; MARV: Marburg virus; MLD: mucin-like domain; NHK/SERPINA1: alpha1-antitrypsin variant null (Hong Kong); NTZ: nitazoxanide; PDI: protein disulfide isomerase; RAVV: Ravn virus; RESTV: Reston ebolavirus; SARS-CoV: severe acute respiratory syndrome coronavirus; SBOV: Sudan ebolavirus; sGP: soluble GP; SQSTM1/p62: sequestosome 1; ssGP: small soluble GP; TAFV: Ta\u00ef Forest ebolavirus; TIZ: tizoxanide; TGN: thapsigargin; TLD: TXN (thioredoxin)-like domain; Ub: ubiquitin; UPR: unfolded protein response; VLP: virus-like particle; VSV: vesicular stomatitis virus; WB: Western blotting; WT: wild-type; XBP1: X-box binding protein 1."

However, there are still no effective antiviral therapies that can completely cure EVD. A comprehensive understanding of virus-host interactions would be beneficial for developing new antiviral agents. Here, we showed that CXCR4-induced macroautophagy/autophagy and was internalized to endosomes by interacting with glycoprotein (GP) on viral particles during EBOV infection; this promoted the EBOV attachment and entry, which was reduced by CXCR4 antagonist and neutralizing antibody. We also found that CXCR4 increased EBOV replication by downregulating cytotoxic GP to promote viral fitness instead of influencing the assembly of viral factory. Mechanistically, excessive EBOV GP could hijack CXCR4 sorting and transporting pathways by their interactions with HGS, one of the key components of the ESCRT machinery; subsequently GP could be carried back to the endoplasmic reticulum by CXCR4, where the E3 ubiquitin ligase RNF185 was recruited to polyubiquitinate GP in a K27- and K63-linked manner. Finally, polyubiquitinated GP was degraded in lysosomes via reticulophagy by interacting with RETREG1 (reticulophagy regulator 1), in an ATG3- and ATG5-dependent manner. Our findings revealed dual roles of CXCR4 in regulation of EBOV life cycle, either acting as an entry factor by interacting with GP on viral particles to facilitate viral entry or targeting excessive GP for reticulophagic degradation, providing new evidence that EBOV hijacked the host vesicular transportation system through efficient virus-host interactions to facilitate viral fitness.Abbreviations: Baf A1: bafilomycin A1; BDBV: Bundibugyo Ebolavirus; CHX: cycloheximide; CXCR4: C-X-C motif chemokine receptor 4; CLEC4M/DC-SIGNR: C type lectin domain family 4 member M; EBOV: Zaire Ebolavirus; EEA1: early endosome antigen 1; ER: endoplasmic reticulum; ERAD: ER-associated degradation; ESCRT: endosomal sorting complex required for transport; EVD: Ebolavirus disease; HAVCR1/TIM-1: hepatitis A virus cellular receptor 1; GP: glycoprotein; HGS: hepatocyte growth factor-regulated tyrosine kinase substrate; HIV: human immunodeficiency virus; IFL: internal fusion loop; ITCH/AIP4: itchy E3 ubiquitin protein ligase; LAMP: lysosomal associated membrane protein; LC-MS/MS: liquid chromatography mass spectrometry; PDIs: protein disulfide isomerases; RBD: receptor binding domain; RESTV: Reston Ebolavirus; RETREG1: reticulophagy regulator 1; RNF185: ring finger protein 185; SQSTM1/p62: sequestosome 1; SUDV: Sudan Ebolavirus; TAFV: Ta\u00ef Forest Ebolavirus; TRIM21: tripartite motif containing 21; trVLPs: transcription- and replication-competent virus-like particles; Ub: ubiquitin."

The proteostasis network in the endoplasmic reticulum (ER) is composed of the calnexin cycle, and the two protein degradation pathways ER-associated protein degradation (ERAD) and ER-to-lysosome-associated degradation (ERLAD/ER-phagy/reticulophagy). Here we show that calnexin and calreticulin trigger Zaire Ebolavirus (EBOV) glycoprotein GP1,2 misfolding. Misfolded EBOV-GP1,2 is targeted by ERAD machinery, but this results in lysosomal instead of proteasomal degradation. Moreover, the ER Ub ligase RNF185, usually associated with ERAD, polyubiquitinates EBOV-GP1,2 on lysine 673 via ubiquitin K27-linkage. Polyubiquinated GP1,2 is subsequently recruited into autophagosomes by the soluble autophagy receptor sequestosome 1 (SQSTM1/p62), in an ATG3- and ATG5-dependent manner.

Microglia, the resident immune cells of the central nervous system, orchestrate responses to ischemic injury and critically influence neurovascular remodeling, axonal reorganization, and functional recovery. Emerging evidence indicates that inflammatory preconditioning can reprogram microglial responses to subsequent insults, yet the exact intracellular signaling pathways mediating this adaptive state remain incompletely defined. Here, we used a chemogenetic approach to selectively activate Gq signaling in microglia employing a microglia-specific DREADD mouse model. This strategy mimics Gq-coupled receptor activation in microglia in the absence of peripheral immune engagement. Pre-ischemic Gq activation significantly reduced infarct sizes at 24\u2009h after experimental stroke in female mice and at 7\u2009days in both sexes. Morphological analyses revealed that Gq-conditioned microglia exhibited increased structural complexity, adopting a highly ramified, spatially compact phenotype and higher CD68 expression, indicating increased phagocytic activity. Transcriptional profiling demonstrated that Gq activation primes autophagy-related defense pathways in microglia, resulting in upregulation of interferon-stimulated genes 7\u2009days after stroke in both sexes. Together, our findings identify Gq signaling as a key modulatory pathway capable of reprogramming microglial phenotype and enhancing stroke recovery. These results highlight the plasticity of microglial signaling networks and support targeted modulation of microglial Gq pathways."

These functions are often described as linear pathways of lipogenesis, lipolysis, fatty acid oxidation and thermogenesis. However, lipid handling in adipocytes is spatially organized by organelle contact sites. The endoplasmic reticulum (ER), lipid droplets (LDs), mitochondria, peroxisomes and lysosomes form dynamic interfaces that determine whether fatty acids are stored safely, mobilized for oxidation, processed into specialized lipid species or redirected toward lipotoxic intermediates. In this review, we synthesize evidence that ER-LD and LD-mitochondria contacts coordinate lipid storage and oxidative use, whereas peroxisome-centred contacts connect lipolysis, very-long-chain and branched-chain fatty acid processing, plasmalogen metabolism and mitochondrial remodelling. We further discuss how autophagy and lysosomal pathways maintain adipocyte quality control by regulating LD turnover, mitophagy and membrane renewal. Finally, we propose that obesity, insulin resistance, ectopic lipid deposition, lipodystrophy and adipose inflammation can be viewed as different manifestations of impaired spatial lipid routing. This framework does not replace classical metabolic models, but provides a mechanistic layer that may help identify contact-site-dependent vulnerabilities in metabolic disease."

After oral administration, low-power 980 nm excitation yields 800 nm emission for bioimaging, whereas high-power excitation generates strong 365 nm emission that cleaves the ONB linker and locally releases active 5-FU. In vitro studies confirmed light-gated and power-dependent drug release, while cellular and orthotopic CRC studies demonstrated potent tumor inhibition with minimal systemic toxicity.

In this review, the immunotherapy strategies, biomaterials, devices, and diseases supposed to be treated by immunotherapeutic strategies are reviewed. Several transdermal therapeutic methods, including semisolids, skin patches, chemical, and physical skin penetration enhancers, are discussed. MNs are the most frequent devices implemented in transdermal immunotherapy of cancers (e.g., melanoma, squamous cell carcinoma, cervical, and breast cancer), infectious (e.g., COVID-19), allergic and autoimmune disorders (e.g., Duchenne's muscular dystrophy and Pollinosis). The biomaterials used in transdermal immunotherapy vary in shape, size, and sensitivity to external stimuli (e.g., magnetic field, photo, redox, pH, thermal, and even multi-stimuli-responsive) were reported. Correspondingly, vesicle-based NPs, including niosomes, transferosomes, ethosomes, microemulsions, transfersomes, and exosomes, are also discussed.

Central to this progress is the development of materials that integrate mechanical compliance, reliable signal transduction, and long-term biocompatibility. Conductive hydrogels have emerged as a promising platform, combining tissue-like mechanics with tunable ionic/electronic conductivity to enable stable and conformal biointerfaces. This Review examines how materials design and nanocomposite engineering govern charge transport, mechanical robustness, and dynamic responsiveness, and how these structure-property relationships translate into device performance. Representative applications span metabolic, cardiovascular, and neurological monitoring, as well as wound care, sleep analysis, and biomarker detection. We further identify key challenges for clinical translation, including long-term stability, multimodal integration, and data reliability, and outline future directions toward integrated, intelligent, and closed-loop bioelectronic systems."

Six databases were electronically searched from inception to January 2025. We included original studies reporting biological findings obtained from skeletal muscle biopsies of adults with critical illness. Bibliometrics, characteristics of the patients/controls, and biological findings were extracted in duplicate. Descriptive statistics of biological findings were performed. Random-effects meta-analyses investigated mean differences (MDs) in myofiber cross-sectional area and protein turnover compared with controls. From 22,035 titles screened, 75 studies (n = 2,023 patients; n = 642 controls) published between 1988 and 2024 were included, with 48 unique patient datasets. Biopsies were mainly collected from vastus lateralis (64 [85%] studies) during the first ICU week (50% of studies) and post-ICU (9%). Biological findings included predominant type II myofiber atrophy with necrosis and structural degeneration, mitochondrial dysfunction, inflammatory/fibrotic changes, and upregulated ubiquitin-proteasome/autophagy pathways. Data from six studies (n = 100 patients; 193 controls) indicated that cross-sectional area was 22% lower in patients with critical illness before (MD, -689 \u00b5m2; 95% CI, -1265 to -113 \u00b5m2; p = 0.02) and after (MD, -775 \u00b5m2; 95% CI, -1512 to -37 \u00b5m2; p = 0.04) ICU discharge. Across seven studies (n = 126 patients; 61 controls) protein synthesis was not significantly different in patients with critical illness compared with controls (MD, 0.007%/hr; 95% CI, -0.010 to 0.027; p = 0.36). Protein degradation pathway markers were significantly higher (standardized MD ranging, 0.5-1.7) in data from 11 studies (n = 439 patients; 163 controls). Muscle wasting during critical illness reflects multifaceted biological disturbances. While myofiber size is significantly lower in patients with critical illness, pooled analyses show no significant differences in muscle protein synthesis compared with non-ICU controls, whereas protein degradation markers are consistently higher."

The lack of effective vaccines and emergence of drug-resistant flukes have prompted research into alternative treatments. Metallic nanoparticles have recently been studied for their potential as anthelmintic agents. This research examined the in vitro anthelmintic activity of copper oxide (CuO-NPs) and zinc oxide nanoparticles (ZnO-NPs) against Dicrocoelium dendriticum. Using adult motility inhibition tests and oxidative stress biomarkers, including glutathione peroxidase , glutathione S-transferase , superoxide dismutase , and malondialdehyde , this study evaluated the effects of CuO-NPs and ZnO-NPs. Flukes were treated with various concentrations of nanoparticles (1.00, 4.00, 8.00, 12.00, and 16.00 ppm) for 24 hr. The CuO-NPs and ZnO-NPs demonstrated concentration- and time-dependent anthelmintic activity. Higher concentrations (12.00 and 16.00 ppm of CuO-NPs, and 16.00 ppm of ZnO-NPs) significantly inhibited worm motility compared to the controls. The nanoparticles induced oxidative stress in the flukes, with decreased superoxide dismutase, glutathione S-transferase, and glutathione peroxidase activities and increased malondialdehyde levels. Based on these findings, CuO-NPs and ZnO-NPs exhibit potential as therapeutic agents for controlling and treating D. dendriticum. However, further studies are necessary to assess their safety and efficacy in vivo for managing parasitic infections."

This study aimed to investigate the effects of Bangle extract (BaE) on inflammation and autophagy in the colons of mice with dextran sulfate sodium (DSS)-induced colitis. Male C57BL/6J mice were assigned to four groups: control, DSS\u00a0+\u00a00% BaE, DSS\u00a0+\u00a01% BaE, and DSS\u00a0+\u00a03% BaE. The BaE groups were fed BaE diets for 3 weeks, followed by an additional week of BaE diets and 3% DSS in the water. The control group received a standard chow diet and water for 4 weeks.

The LFV Z protein plays a central role in virion assembly and egress, such that independent expression of LFV Z leads to the production of virus-like particles (VLPs) that mimic egress of infectious virus. LFV Z contains both PTAP and PPPY L-domain motifs that are known to recruit host proteins that are important for mediating efficient virus egress and spread. The viral PPPY motif is known to interact with specific host WW-domain bearing proteins. Here we identified host WW-domain bearing protein BCL2 Associated Athanogene 3 (BAG3) as a LFV Z PPPY interactor using our proline-rich reading array of WW-domain containing mammalian proteins. BAG3 is a stress-induced molecular co-chaperone that functions to regulate cellular protein homeostasis and cell survival via Chaperone-Assisted Selective Autophagy (CASA). Similar to our previously published findings for the VP40 proteins of Ebola and Marburg viruses, our results using VLP budding assays, BAG3 knockout cells, and confocal microscopy indicate that BAG3 is a WW-domain interactor that negatively regulates egress of LFV Z VLPs, rather than promoting VLP release. Our results suggest that CASA and specifically BAG3 may represent a novel host defense mechanism, whereby BAG3 may dampen egress of several hemorrhagic fever viruses by interacting and interfering with the budding function of viral PPxY-containing matrix proteins."

Pharmacological inhibition of either the early stage formation of the VP40/BAG3/HSP70 tripartite complex, or late stage formation of autolysosomes, rescued VP40 VLP egress back to WT levels. The mechanistic target of rapamycin complex 1 (mTORC1) is a master regulator of autophagy, and we found that surface expression of EBOV GP on either VLPs or an infectious VSV recombinant virus, activated mTORC1. Notably, pharmacological suppression of mTORC1 signaling by rapamycin activated CASA in a BAG3-dependent manner to restrict the egress of both VLPs and infectious EBOV in Huh7 cells.

The filovirus VP40 matrix protein is essential for virus assembly and budding, and its PPxY L-domain motif interacts with WW-domains of specific host proteins, such as Nedd4 and ITCH, to facilitate the late stage of virus-cell separation. To identify additional WW-domain-bearing host proteins that interact with VP40, we used an EBOV PPxY-containing peptide to screen an array of 115 mammalian WW-domain-bearing proteins. Using this unbiased approach, we identified BCL2 Associated Athanogene 3 (BAG3), a member of the BAG family of molecular chaperone proteins, as a specific VP40 PPxY interactor. Here, we demonstrate that the WW-domain of BAG3 interacts with the PPxY motif of both EBOV and MARV VP40 and, unexpectedly, inhibits budding of both eVP40 and mVP40 virus-like particles (VLPs), as well as infectious VSV-EBOV recombinants. BAG3 is a stress induced protein that regulates cellular protein homeostasis and cell survival through chaperone-mediated autophagy (CMA). Interestingly, our results show that BAG3 alters the intracellular localization of VP40 by sequestering VP40 away from the plasma membrane. As BAG3 is the first WW-domain interactor identified that negatively regulates budding of VP40 VLPs and infectious virus, we propose that the chaperone-mediated autophagy function of BAG3 represents a specific host defense strategy to counteract the function of VP40 in promoting efficient egress and spread of virus particles."

Traditional antiviral treatments are often undermined by fast-mutating viruses, drug resistance, and newly emerging pathogens.

PROTACs excel at specifically degrading pathogenic proteins, offering a targeted and efficient antiviral strategy. We also investigate the potential of exosome-based diagnostic technologies, which harness cell-derived nanovesicles for non-invasive sampling and early viral infection detection. Addressing the challenge of PROTAC delivery, we introduce a groundbreaking strategy utilizing exosomes to deliver PROTACs with improved precision and as a targeted delivery vehicle. Integrating these innovative strategies provides a novel approach to combat RNA zoonotic viral diseases, paving the way for a new era in antiviral therapy."

Nano-sized endosomal vesicles called exosomes have gained considerable attention from researchers due to their role in intracellular communication to regulate the biological activity of target cells through cargo proteins, nucleic acids, and lipids. According to recent studies, exosomes play a vital role in viral diseases including covid-19, with their interaction with the host immune system opening the door to effective antiviral treatments. Utilizing the intrinsic nature of exosomes, it is imperative to elucidate how exosomes exert their effect on the immune system or boost viral infectivity. Exosome biogenesis machinery is hijacked by viruses to initiate replication, spread infection, and evade the immune response. Exosomes, however, also participate in protective mechanisms by triggering the innate immune system. Besides that, exosomes released from the cells can carry a robust amount of information about the diseased state, serving as a potential biomarker for detecting viral diseases. This review describes how exosomes increase virus infectivity, act as immunomodulators, and function as a potential drug delivery carrier and diagnostic biomarker for diseases caused by HIV, Hepatitis, Ebola, and Epstein-Barr viruses. Furthermore, the review analyzes various applications of exosomes within the context of COVID-19, including its management."

EBOV infection is dependent on its structural glycoprotein (GP), but high levels of GP expression also trigger cell rounding, detachment, and downregulation of many surface molecules that is thought to contribute to its high pathogenicity. Thus, EBOV has evolved an RNA editing mechanism to reduce its GP expression and increase its fitness. We now report that the GP expression is also suppressed at the protein level in cells by protein disulfide isomerases (PDIs). Although PDIs promote oxidative protein folding by catalyzing correct disulfide formation in the endoplasmic reticulum (ER), PDIA3/ERp57 adversely triggered the GP misfolding by targeting GP cysteine residues and activated the unfolded protein response (UPR). Abnormally folded GP was targeted by ER-associated protein degradation (ERAD) machinery and, unexpectedly, was degraded via the macroautophagy/autophagy-lysosomal pathway, but not the proteasomal pathway. PDIA3 also decreased the GP expression from other ebolavirus species but increased the GP expression from Marburg virus (MARV), which is consistent with the observation that MARV-GP does not cause cell rounding and detachment, and MARV does not regulate its GP expression via RNA editing during infection. Furthermore, five other PDIs also had a similar inhibitory activity to EBOV-GP. Thus, PDIs negatively regulate ebolavirus glycoprotein expression, which balances the viral life cycle by maximizing their infection but minimizing their cellular effect. We suggest that ebolaviruses hijack the host protein folding and ERAD machinery to increase their fitness via reticulophagy during infection.Abbreviations: 3-MA: 3-methyladenine; 4-PBA: 4-phenylbutyrate; ACTB: \u03b2-actin; ATF: activating transcription factor; ATG: autophagy-related; BafA1: bafilomycin A1; BDBV: Bundibugyo ebolavirus; CALR: calreticulin; CANX: calnexin; CHX: cycloheximide; CMA: chaperone-mediated autophagy; ConA: concanamycin A; CRISPR: clusters of regularly interspaced short palindromic repeats; Cas9: CRISPR-associated protein 9; dsRNA: double-stranded RNA; EBOV: Zaire ebolavirus; EDEM: ER degradation enhancing alpha-mannosidase like protein; EIF2AK3/PERK: eukaryotic translation initiation factor 2 alpha kinase 3; Env: envelope glycoprotein; ER: endoplasmic reticulum; ERAD: ER-associated protein degradation; ERN1/IRE1: endoplasmic reticulum to nucleus signaling 1; GP: glycoprotein; HA: hemagglutinin; HDAC6: histone deacetylase 6; HMM: high-molecular-mass; HIV-1: human immunodeficiency virus type 1; HSPA5/BiP: heat shock protein family A (Hsp70) member 5; IAV: influenza A virus; IP: immunoprecipitation; KIF: kifenesine; Lac: lactacystin; LAMP: lysosomal associated membrane protein; MAN1B1/ERManI: mannosidase alpha class 1B member 1; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; MARV: Marburg virus; MLD: mucin-like domain; NHK/SERPINA1: alpha1-antitrypsin variant null (Hong Kong); NTZ: nitazoxanide; PDI: protein disulfide isomerase; RAVV: Ravn virus; RESTV: Reston ebolavirus; SARS-CoV: severe acute respiratory syndrome coronavirus; SBOV: Sudan ebolavirus; sGP: soluble GP; SQSTM1/p62: sequestosome 1; ssGP: small soluble GP; TAFV: Ta\u00ef Forest ebolavirus; TIZ: tizoxanide; TGN: thapsigargin; TLD: TXN (thioredoxin)-like domain; Ub: ubiquitin; UPR: unfolded protein response; VLP: virus-like particle; VSV: vesicular stomatitis virus; WB: Western blotting; WT: wild-type; XBP1: X-box binding protein 1."

However, there are still no effective antiviral therapies that can completely cure EVD. A comprehensive understanding of virus-host interactions would be beneficial for developing new antiviral agents. Here, we showed that CXCR4-induced macroautophagy/autophagy and was internalized to endosomes by interacting with glycoprotein (GP) on viral particles during EBOV infection; this promoted the EBOV attachment and entry, which was reduced by CXCR4 antagonist and neutralizing antibody. We also found that CXCR4 increased EBOV replication by downregulating cytotoxic GP to promote viral fitness instead of influencing the assembly of viral factory. Mechanistically, excessive EBOV GP could hijack CXCR4 sorting and transporting pathways by their interactions with HGS, one of the key components of the ESCRT machinery; subsequently GP could be carried back to the endoplasmic reticulum by CXCR4, where the E3 ubiquitin ligase RNF185 was recruited to polyubiquitinate GP in a K27- and K63-linked manner.

Our findings revealed dual roles of CXCR4 in regulation of EBOV life cycle, either acting as an entry factor by interacting with GP on viral particles to facilitate viral entry or targeting excessive GP for reticulophagic degradation, providing new evidence that EBOV hijacked the host vesicular transportation system through efficient virus-host interactions to facilitate viral fitness.Abbreviations: Baf A1: bafilomycin A1; BDBV: Bundibugyo Ebolavirus; CHX: cycloheximide; CXCR4: C-X-C motif chemokine receptor 4; CLEC4M/DC-SIGNR: C type lectin domain family 4 member M; EBOV: Zaire Ebolavirus; EEA1: early endosome antigen 1; ER: endoplasmic reticulum; ERAD: ER-associated degradation; ESCRT: endosomal sorting complex required for transport; EVD: Ebolavirus disease; HAVCR1/TIM-1: hepatitis A virus cellular receptor 1; GP: glycoprotein; HGS: hepatocyte growth factor-regulated tyrosine kinase substrate; HIV: human immunodeficiency virus; IFL: internal fusion loop; ITCH/AIP4: itchy E3 ubiquitin protein ligase; LAMP: lysosomal associated membrane protein; LC-MS/MS: liquid chromatography mass spectrometry; PDIs: protein disulfide isomerases; RBD: receptor binding domain; RESTV: Reston Ebolavirus; RETREG1: reticulophagy regulator 1; RNF185: ring finger protein 185; SQSTM1/p62: sequestosome 1; SUDV: Sudan Ebolavirus; TAFV: Ta\u00ef Forest Ebolavirus; TRIM21: tripartite motif containing 21; trVLPs: transcription- and replication-competent virus-like particles; Ub: ubiquitin."

The proteostasis network in the endoplasmic reticulum (ER) is composed of the calnexin cycle, and the two protein degradation pathways ER-associated protein degradation (ERAD) and ER-to-lysosome-associated degradation (ERLAD/ER-phagy/reticulophagy). Here we show that calnexin and calreticulin trigger Zaire Ebolavirus (EBOV) glycoprotein GP1,2 misfolding. Misfolded EBOV-GP1,2 is targeted by ERAD machinery, but this results in lysosomal instead of proteasomal degradation. Moreover, the ER Ub ligase RNF185, usually associated with ERAD, polyubiquitinates EBOV-GP1,2 on lysine 673 via ubiquitin K27-linkage. Polyubiquinated GP1,2 is subsequently recruited into autophagosomes by the soluble autophagy receptor sequestosome 1 (SQSTM1/p62), in an ATG3- and ATG5-dependent manner. We conclude that EBOV hijacks all three proteostasis mechanisms in the ER to downregulate GP1,2 via polyubiquitination and show that this increases viral fitness. This study identifies linkages among proteostasis network components previously thought to function independently."

Microglia, the resident immune cells of the central nervous system, orchestrate responses to ischemic injury and critically influence neurovascular remodeling, axonal reorganization, and functional recovery. Emerging evidence indicates that inflammatory preconditioning can reprogram microglial responses to subsequent insults, yet the exact intracellular signaling pathways mediating this adaptive state remain incompletely defined. Here, we used a chemogenetic approach to selectively activate Gq signaling in microglia employing a microglia-specific DREADD mouse model. This strategy mimics Gq-coupled receptor activation in microglia in the absence of peripheral immune engagement. Pre-ischemic Gq activation significantly reduced infarct sizes at 24\u2009h after experimental stroke in female mice and at 7\u2009days in both sexes. Morphological analyses revealed that Gq-conditioned microglia exhibited increased structural complexity, adopting a highly ramified, spatially compact phenotype and higher CD68 expression, indicating increased phagocytic activity. Transcriptional profiling demonstrated that Gq activation primes autophagy-related defense pathways in microglia, resulting in upregulation of interferon-stimulated genes 7\u2009days after stroke in both sexes. Together, our findings identify Gq signaling as a key modulatory pathway capable of reprogramming microglial phenotype and enhancing stroke recovery. These results highlight the plasticity of microglial signaling networks and support targeted modulation of microglial Gq pathways."

"abstract_text": "ID: 42567497\nTitle: Organelle contact sites as spatial regulators of lipid fate in adipose tissue metabolic disease.\nAbstract: Adipose tissue protects metabolic homeostasis by storing excess fatty acids, releasing fuels during energy demand and coordinating endocrine and inflammatory signals. These functions are often described as linear pathways of lipogenesis, lipolysis, fatty acid oxidation and thermogenesis. However, lipid handling in adipocytes is spatially organized by organelle contact sites. The endoplasmic reticulum (ER), lipid droplets (LDs), mitochondria, peroxisomes and lysosomes form dynamic interfaces that determine whether fatty acids are stored safely, mobilized for oxidation, processed into specialized lipid species or redirected toward lipotoxic intermediates. In this review, we synthesize evidence that ER-LD and LD-mitochondria contacts coordinate lipid storage and oxidative use, whereas peroxisome-centred contacts connect lipolysis, very-long-chain and branched-chain fatty acid processing, plasmalogen metabolism and mitochondrial remodelling. We further discuss how autophagy and lysosomal pathways maintain adipocyte quality control by regulating LD turnover, mitophagy and membrane renewal. Finally, we propose that obesity, insulin resistance, ectopic lipid deposition, lipodystrophy and adipose inflammation can be viewed as different manifestations of impaired spatial lipid routing. This framework does not replace classical metabolic models, but provides a mechanistic layer that may help identify contact-site-dependent vulnerabilities in metabolic disease."

Herein, we present near-infrared (NIR)-activated enteric prodrug microparticles, HPMCP@L-UCNPs-ONB-5-FU, which enable spatiotemporally controlled release of 5-FU in the colon. The photocleavable prodrug o-nitrobenzyl-5-fluorouracil (ONB-5-FU) is conjugated to large upconversion nanoparticles (L-UCNPs) and encapsulated within the enteric polymer hydroxypropyl methylcellulose phthalate (HPMCP) to resist gastric degradation. After oral administration, low-power 980 nm excitation yields 800 nm emission for bioimaging, whereas high-power excitation generates strong 365 nm emission that cleaves the ONB linker and locally releases active 5-FU. In vitro studies confirmed light-gated and power-dependent drug release, while cellular and orthotopic CRC studies demonstrated potent tumor inhibition with minimal systemic toxicity. Overall, this work establishes a precise and biocompatible NIR-controlled prodrug activation paradigm for oral chemotherapy of CRC."

For this reason, immunotherapy has attracted a great deal of attention and numerous studies on different approaches for immunotherapies have been investigated, using multiple biomaterials and carriers, from nanoparticles (NPs) to microneedles (MNs). In this review, the immunotherapy strategies, biomaterials, devices, and diseases supposed to be treated by immunotherapeutic strategies are reviewed. Several transdermal therapeutic methods, including semisolids, skin patches, chemical, and physical skin penetration enhancers, are discussed. MNs are the most frequent devices implemented in transdermal immunotherapy of cancers (e.g., melanoma, squamous cell carcinoma, cervical, and breast cancer), infectious (e.g., COVID-19), allergic and autoimmune disorders (e.g., Duchenne's muscular dystrophy and Pollinosis). The biomaterials used in transdermal immunotherapy vary in shape, size, and sensitivity to external stimuli (e.g., magnetic field, photo, redox, pH, thermal, and even multi-stimuli-responsive) were reported. Correspondingly, vesicle-based NPs, including niosomes, transferosomes, ethosomes, microemulsions, transfersomes, and exosomes, are also discussed.

Six databases were electronically searched from inception to January 2025. We included original studies reporting biological findings obtained from skeletal muscle biopsies of adults with critical illness. Bibliometrics, characteristics of the patients/controls, and biological findings were extracted in duplicate. Descriptive statistics of biological findings were performed. Random-effects meta-analyses investigated mean differences (MDs) in myofiber cross-sectional area and protein turnover compared with controls. From 22,035 titles screened, 75 studies (n = 2,023 patients; n = 642 controls) published between 1988 and 2024 were included, with 48 unique patient datasets. Biopsies were mainly collected from vastus lateralis (64 [85%] studies) during the first ICU week (50% of studies) and post-ICU (9%). Biological findings included predominant type II myofiber atrophy with necrosis and structural degeneration, mitochondrial dysfunction, inflammatory/fibrotic changes, and upregulated ubiquitin-proteasome/autophagy pathways. Data from six studies (n = 100 patients; 193 controls) indicated that cross-sectional area was 22% lower in patients with critical illness before (MD, -689 \u00b5m2; 95% CI, -1265 to -113 \u00b5m2; p = 0.02) and after (MD, -775 \u00b5m2; 95% CI, -1512 to -37 \u00b5m2; p = 0.04) ICU discharge.

Protein degradation pathway markers were significantly higher (standardized MD ranging, 0.5-1.7) in data from 11 studies (n = 439 patients; 163 controls). Muscle wasting during critical illness reflects multifaceted biological disturbances. While myofiber size is significantly lower in patients with critical illness, pooled analyses show no significant differences in muscle protein synthesis compared with non-ICU controls, whereas protein degradation markers are consistently higher."

The lack of effective vaccines and emergence of drug-resistant flukes have prompted research into alternative treatments. Metallic nanoparticles have recently been studied for their potential as anthelmintic agents. This research examined the in vitro anthelmintic activity of copper oxide (CuO-NPs) and zinc oxide nanoparticles (ZnO-NPs) against Dicrocoelium dendriticum. Using adult motility inhibition tests and oxidative stress biomarkers, including glutathione peroxidase , glutathione S-transferase , superoxide dismutase , and malondialdehyde , this study evaluated the effects of CuO-NPs and ZnO-NPs. Flukes were treated with various concentrations of nanoparticles (1.00, 4.00, 8.00, 12.00, and 16.00 ppm) for 24 hr. The CuO-NPs and ZnO-NPs demonstrated concentration- and time-dependent anthelmintic activity. Higher concentrations (12.00 and 16.00 ppm of CuO-NPs, and 16.00 ppm of ZnO-NPs) significantly inhibited worm motility compared to the controls. The nanoparticles induced oxidative stress in the flukes, with decreased superoxide dismutase, glutathione S-transferase, and glutathione peroxidase activities and increased malondialdehyde levels. Based on these findings, CuO-NPs and ZnO-NPs exhibit potential as therapeutic agents for controlling and treating D. dendriticum. However, further studies are necessary to assess their safety and efficacy in vivo for managing parasitic infections."

The LFV Z protein plays a central role in virion assembly and egress, such that independent expression of LFV Z leads to the production of virus-like particles (VLPs) that mimic egress of infectious virus. LFV Z contains both PTAP and PPPY L-domain motifs that are known to recruit host proteins that are important for mediating efficient virus egress and spread. The viral PPPY motif is known to interact with specific host WW-domain bearing proteins. Here we identified host WW-domain bearing protein BCL2 Associated Athanogene 3 (BAG3) as a LFV Z PPPY interactor using our proline-rich reading array of WW-domain containing mammalian proteins. BAG3 is a stress-induced molecular co-chaperone that functions to regulate cellular protein homeostasis and cell survival via Chaperone-Assisted Selective Autophagy (CASA). Similar to our previously published findings for the VP40 proteins of Ebola and Marburg viruses, our results using VLP budding assays, BAG3 knockout cells, and confocal microscopy indicate that BAG3 is a WW-domain interactor that negatively regulates egress of LFV Z VLPs, rather than promoting VLP release. Our results suggest that CASA and specifically BAG3 may represent a novel host defense mechanism, whereby BAG3 may dampen egress of several hemorrhagic fever viruses by interacting and interfering with the budding function of viral PPxY-containing matrix proteins."

In this study, pilot proteomic screening of clinical gastric mucosal samples suggested a progressive decline in Sirtuin 1 abundance along the H. pylori-associated pathological cascade. Based on these findings, gastric epithelial cells-localizable oral nanomedicines (GLONs) are developed, whereby H. pylori eradication and reversal of precancerous intestinal metaplasia (IM) are simultaneously achieved via Sirtuin 1 restoration. GLONs are constructed by coating resveratrol, lactoferrin, and disulfide modified-fucoidan (DFu) co-assembled nanoparticles (RLF) with engineered mucin-overexpressing gastric epithelial cell membranes. The shell of GLONs resists gastric acid, enhances mucus penetration and epithelial cells uptake. After internalization, DFu undergoes oxidative destabilization in the H2O2-enriched infectious microenvironment induced by H. pylori, thereby triggering RLF core dissociation and subsequent component release. The resveratrol restored H. pylori infection-induced impairment of Sirtuin 1, thereby activating autophagy. Meanwhile, lactoferrin promoted antimicrobial peptide production and synergized with fucoidan-mediated enhancement of antigen presentation, ultimately enabling the clearance of both intracellular and extracellular H. pylori. In metaplastic gastric cells, Sirtuin 1 repairs damaged DNA, and inhibits malignant proliferation. In mouse models, under the tested 7-day regimen, GLONs produced greater reductions in gastric H. pylori burden and more pronounced improvements in IM-related phenotypes than the abbreviated triple-therapy. GLONs represent an innovative and highly efficient therapeutic platform for H. pylori infection and its complications."

The ER is subdivided into microdomains mediating one-third of total protein biosynthesis, oxidative protein folding, secretion, protein quality control, calcium signaling, marcoautophagy/autophagy, stress sensing, and apoptosis. Defects in ER-calcium homeostasis underlie several diseases. Damage to the ER by misfolded membrane proteins is suppressed by specific HSPA/Hsp70 and DNAJ/Hsp40 chaperone pairs that select intermediates for ubiquitination and ER-associated degradation (ERAD) via the proteasome. The ER-transmembrane Hsp40 chaperone DNAJB12 and HSPA/Hsp70 also target toxic intermediates of misfolded membrane proteins for ER-associated autophagy (ERAA). DNAJB12-HSPA/Hsp70 maintain membrane protein degradation intermediates in detergent-soluble and degradation-competent states. DNAJB12-HSPA/Hsp70 also interact with the autophagy initiation kinase ULK1 on ER tubules containing ERAD-resistant misfolded membrane proteins (ERAD-RMPs). Omegasomes are ER microdomains where the autophagosome precursor or phagophore (PG) forms. ER tubules loaded with ERAD-RMPs enter omegasomes where they are converted into ER-connected PG (ER-PG). The Atg8 (autophagy related 8)-family member GABARAP (GABA type A receptor-associated protein) facilitates transfer of ERAD-RMPs from ER-PGs to autolysosomes (AL) that dock transiently with omegasomes. This article describes a model for DNAJB12-HSPA/Hsp70 action during the conformation-dependent triage in the ER of misfolded membrane proteins for folding versus proteasomal or AL degradation."

JDPs either target Hsp70s to specific subcellular sites where substrates reside (recruiters) or bind substrates directly by using highly specific (specialists) or multiple, versatile (generalists) binding sites. Through diverse substrate-binding modes and regulatory mechanisms, the 50 human JDPs confer remarkable client specificity to Hsp70s, a function that is comparable to that achieved by close to 600 E3 ubiquitin ligases in targeting proteins for degradation. Moreover, JDPs, together with NEFs, dictate the fate of Hsp70 clients by directing them to distinct protein quality control pathways, resulting in their folding or degradation. These recent mechanistic insights into Hsp70 regulation not only highlight the versatility and complexity of the Hsp70 network but also offer new avenues for more specific interventions in ageing-related and other protein folding diseases."

Increasing evidence suggests that Hsp70 decides the fate of proteins; however, the inherent rules that govern the decision-making capacity of Hsp70 are not clear. In this review, we have articulated the functions of Hsp70 with respect to proteostasis and established a link between its co-chaperones in deciding the fate of the substrate. The substrate binding of Hsp70 is mediated by its catalytic cycle where Hsp70 achieves high- and low-substrate-affinity ADP- and ATP-bound forms, respectively. This catalytic cycle of Hsp70 is maintained by co-chaperones J-domain proteins (JDPs), and nucleotide exchange factors (NEFs). JDPs bind to the ATP-bound form of Hsp70 and hydrolyze ATP that enhances substrate binding, whereas NEFs exchange ADP with ATP and facilitate substrate release. During evolution, several isoforms of Hsp70 and its co-chaperones have emerged which may have functional significance. Apart from facilitating the catalytic cycle of Hsp70, co-chaperones often mediate collaboration between Hsp70 and downstream protein quality-control pathways such as the ubiquitin proteasome system, autophagy, or disaggregase machinery. Therefore, co-chaperones have a significant role in Hsp70's triage decision of whether to fold, hold, or degrade."

WW domain binding protein-2 (WBP2), a molecular chaperon, is involved in the progression of various malignancies, but its role in renal injuries has not been investigated. Our present study employed bioinformatics analysis to identify WBP2 as a potential modulator of AKI and ferroptosis. Preliminary laboratory investigations showed that WBP2, highly expressed in renal proximal tubular cells, was downregulated in CP-AKI. Further studies demonstrated that WBP2 decelerated ferroptosis to alleviate CP-AKI. Mechanistically, WBP2 interacted with glutathione peroxidase 4 (GPX4, a key detoxicating enzyme for ferroptosis) via its PPXY1 motif to inhibit ferroptosis. Furthermore, the in-depth investigations revealed that WBP2 competed with heat shock cognate protein 70 (HSC70) for the binding with the KEFRQ-like motifs of GPX4, leading to the deceleration of chaperon-mediated autophagy of GPX4.

The switch of EGFR downstream signaling from TKI-sensitive to TKI-insensitive is a critical mechanism-driving resistance to TKIs. Identification of potential therapies to target EGFR effectively is a potential strategy to treat TKI-resistant LUADs. In this study, we developed a small molecule diarylheptanoid 35d, a curcumin derivative, that effectively suppressed EGFR protein expression, killed multiple TKI-resistant LUAD cells in\u00a0vitro, and suppressed tumor growth of EGFR-mutant LUAD xenografts with variant TKI-resistant mechanisms including EGFR C797S mutations in\u00a0vivo. Mechanically, 35d triggers heat shock protein 70-mediated lysosomal pathway through transcriptional activation of several components in the pathway, such as HSPA1B, to induce EGFR protein degradation. Interestingly, higher HSPA1B expression in LUAD tumors associated with longer survival of EGFR-mutant, TKI-treated patients, suggesting the role of HSPA1B on retarding TKI resistance and providing a rationale for combining 35d with EGFR TKIs.

Current conventional PD therapies are often limited by significant side effects, underscoring the demand for alternative treatment strategies. Drug repurposing of FDA-approved compounds represents a promising approach to address this unmet clinical need. Here, by integrating clinical data analysis, we identified an association between autophagy impairment and specific PD patient subtypes, suggesting that ULK1-dependent autophagy activation may offer therapeutic benefit. Through systematic screening for autophagy induction and neuroprotective activity, we identified econazole, a known imidazole antifungal, as a promising candidate. Econazole exhibited robust therapeutic effects across multiple PD models, including MPTP-induced zebrafish and mouse models, as well as SNCAA53T mutant mouse models. Notably, its efficacy was dependent on functional autophagy, as autophagy inhibition abrogated its beneficial effects. Mechanistically, econazole activated ULK1, enhanced autolysosome formation, and promoted clearance of SNCA aggregates. Mouse brain microarray analysis indicated that econazole-activated ULK1 suppresses MAP3K12/DLK-MAPK8/JNK-MAPK9/JNK2-mediated neuronal apoptosis. Further phosphoproteomic profiling uncovered a novel ULK1-HSPA8/Hsc70 interaction that promotes LAMP1 and LAMP2 activation and enhances lysosomal function. This ULK1-HSPA8 complex additionally activated the BECN1 (beclin 1) complex to facilitate autophagosome formation. Together, our findings highlight a clinical data-guided drug repurposing approach that identifies econazole as a potent autophagy activator with therapeutic efficacy in ULK1-linked PD models, opening new avenues for PD treatment.Abbreviations: 3-MA: 3-methyladenine; ACTB: actin beta; ATG: autophagy related; AUC: area under the curve; BafA1: bafilomycin A1; BECN1: beclin 1; CMA: chaperone-mediated autophagy; DA: dopamine; DOPAC: 3,4-dihydroxyphenylacetic acid; Econ: econazole; GFP: green fluorescent protein; HEK-293T: human embryonic kidney 293T; HSPA8: heat shock protein 8 family A (Hsp70) member 8; HVA: homovanillic acid; JUN: Jun proto-oncogene, AP-1 transcription factor subunit; KSEA: kinase-substrate enrichment analysis; LAMP: lysosome associated membrane protein; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; MAP2K: mitogen-activated protein kinase kinase; MAP3K12: mitogen-activated protein kinase kinase kinase 12; MAPK: mitogen-activated protein kinase; MPP+: 1-methyl-4-phenylpyridinium; MPTP: 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine; PD: Parkinson disease; RB1CC1: RB1 inducible coiled-coil 1; RFP: red fluorescent protein; RMSD: root mean square deviation; SEM: standard error of the mean; SNCA: synuclein alpha; SQSTM1: sequestosome 1; SYP: synaptophysin; TFEB: transcription factor EB; TH: tyrosine hydroxylase; ULK1: unc-51 like autophagy activating kinase 1; WT: wild-type."

Proteins in the extracellular milieu face numerous challenges that can lead to protein misfolding and aggregation. As a checkpoint for proteins that move between cells, extracellular chaperone networks are of growing clinical relevance. J-domain proteins (JDPs) are ubiquitous molecular chaperones that are known for their essential roles in a wide array of fundamental cellular processes through their regulation of heat shock protein 70s. As the largest molecular chaperone family, JDPs have long been recognized for their diverse functions within cells. Some JDPs are elegantly selective for their \"client proteins,\" some do not discriminate among substrates and others act cooperatively on the same target. The realization that JDPs are exported through both classical and unconventional secretory pathways has fueled investigation into the roles that JDPs play in protein quality control and intercellular communication. The proposed functions of exported JDPs are diverse. Studies suggest that export of DnaJB11 enhances extracellular proteostasis, that intercellular movement of DnaJB1 or DnaJB6 enhances the proteostasis capacity in recipient cells, whereas the import of DnaJB8 increases resistance to chemotherapy in recipient cancer cells. In addition, the export of DnaJC5 and concurrent DnaJC5-dependent ejection of dysfunctional and aggregation-prone proteins are implicated in the prevention of neurodegeneration. This review provides a brief overview of the current understanding of the extracellular chaperone networks and outlines the first wave of studies describing the cellular export of JDPs."

We have previously reported that CVB3 induces mitochondrial fission and mitophagy while inhibiting lysosomal degradation by blocking autophagosome-lysosome fusion. This promotes the release of virus-laden mitophagosomes from host cells as infectious extracellular vesicles (EVs), enabling non-lytic viral egress. Transient receptor potential vanilloid 1 (TRPV1), a heat and capsaicin-sensitive cation channel, regulates mitochondrial dynamics by inducing mitochondrial membrane depolarization and fission. In this study, we found that TRPV1 activation by capsaicin dramatically enhances CVB3 egress from host cells via EVs. Released EVs revealed increased levels of viral capsid protein VP1, mitochondrial protein TOM70, and fission protein phospho-DRP1. Moreover, these EVs were enriched in heat shock protein HSP70, suggesting its role in facilitating infectious EV release from cells. Furthermore, TRPV1 inhibition with capsazepine and SB-366791 significantly reduced viral infection in vitro. Our in vivo studies also found that SB-366791 significantly mitigates pancreatic damage and reduces viral titers in a mouse model of CVB3 pancreatitis. Given the lack of understanding regarding factors that contribute to diverse clinical manifestations of CVB3, our study highlights capsaicin and TRPV1 as potential exacerbating factors that facilitate CVB3 dissemination via mitophagy-derived EVs."

Molecular chaperones like Hsp70 and Hsp90 fulfill well-defined roles in protein folding and conformational stability via ATP-dependent reaction cycles. These folding cycles are controlled by associations with a cohort of non-client protein co-chaperones, such as Hop, p23, and Aha1. Pro-folding co-chaperones facilitate the transit of the client protein through the chaperone-mediated folding process. However, chaperones are also involved in proteasomal and lysosomal degradation of client proteins. Like folding complexes, the ability of chaperones to mediate protein degradation is regulated by co-chaperones, such as the C-terminal Hsp70-binding protein (CHIP/STUB1). CHIP binds to Hsp70 and Hsp90 chaperones through its tetratricopeptide repeat (TPR) domain and functions as an E3 ubiquitin ligase using a modified RING finger domain (U-box). This unique combination of domains effectively allows CHIP to network chaperone complexes to the ubiquitin-proteasome and autophagosome-lysosome systems. This chapter reviews the current understanding of CHIP as a co-chaperone that switches Hsp70/Hsp90 chaperone complexes from protein folding to protein degradation."

Herein, a self-amplifying ROS-responsive nanovesicle system (CQ/Cu@CT) is designed to enhance oxidative stress while blocking autophagy. Firstly, amphiphilic oligochitosan derivative COS-PEG2KTA-UB is synthesized, where ROS-responsive thioketal acetal (TA) is introduced in form of cinnamaldehyde (CA) prodrug. This polymer self-assembles into nanovesicles, integrating chloroquine (CQ) and supplemental TA to immobilize Cu2+ via carboxylic coordination. Intracellular ROS triggers nanovesicle dissociation to release CA, Cu2+, and CQ. CA induces mitochondrial dysfunction and ROS burst, while Cu2+ depletes glutathione and generates Cu+ for Fenton-like reactions to produce hydroxyl radicals. Meanwhile, due to the inhibition effect of CQ on protective autophagy, CQ/Cu@CT produces significantly high ROS level. The amplified ROS not only aggravates oxidative stress but also accelerates drug release from nanovesicles, which facilitates the drug action against tumors. CQ/Cu@CT also induces immunogenic cell death (ICD) to stimulate dendritic cell maturation and enhance cytotoxic T lymphocyte infiltration. Consequently, CQ/Cu@CT inhibits tumor growth by 67.8\u00a0% in a subcutaneous 4\u00a0T1 tumor model. This study provides a potent strategy to enhance oxidative stress-based cancer therapy."

Although CHRN internalization is well established in MG pathogenesis, the downstream cellular events, especially those related to autophagy, remain poorly described. Here, we report that RAPSN/rapsyn, an intracellular CHRN-binding protein essential for its clustering, accumulates as aggregates in experimental autoimmune myasthenia gravis (EAMG) mice. In CHRN antibody-treated myotubes, RAPSN dissociates from internalized CHRN and forms aggregates due to exposure of its hydrophobic domains. These aggregates in turn impair the trafficking and membrane incorporation of newly synthesized CHRN, thereby exacerbating CHRN loss. Notably, the accumulation of RAPSN aggregates facilitates formation of HSPA/HSP70-BAG3 complex, which recognizes and transports the aggregates along microtubules to form perinuclear aggresomes for subsequent lysosomal degradation. Accordingly, pharmacological inhibition or knockdown of HSPA-BAG3 complex increases RAPSN aggregation, which participates in enhanced CHRN loss and worsened muscle weakness in EAMG mice.

The ER is subdivided into microdomains mediating one-third of total protein biosynthesis, oxidative protein folding, secretion, protein quality control, calcium signaling, marcoautophagy/autophagy, stress sensing, and apoptosis. Defects in ER-calcium homeostasis underlie several diseases. Damage to the ER by misfolded membrane proteins is suppressed by specific HSPA/Hsp70 and DNAJ/Hsp40 chaperone pairs that select intermediates for ubiquitination and ER-associated degradation (ERAD) via the proteasome. The ER-transmembrane Hsp40 chaperone DNAJB12 and HSPA/Hsp70 also target toxic intermediates of misfolded membrane proteins for ER-associated autophagy (ERAA). DNAJB12-HSPA/Hsp70 maintain membrane protein degradation intermediates in detergent-soluble and degradation-competent states. DNAJB12-HSPA/Hsp70 also interact with the autophagy initiation kinase ULK1 on ER tubules containing ERAD-resistant misfolded membrane proteins (ERAD-RMPs). Omegasomes are ER microdomains where the autophagosome precursor or phagophore (PG) forms. ER tubules loaded with ERAD-RMPs enter omegasomes where they are converted into ER-connected PG (ER-PG).

This study explores whether SORT1 is targeted for degradation by chaperone-mediated autophagy (CMA), a selective protein degradation pathway that directs proteins containing KFERQ-like motifs to lysosomes via LAMP2A (lysosomal-associated membrane protein 2A). Silencing LAMP2A or HSPA8/Hsc70 with siRNA increased cytosolic SORT1 protein levels.

Furthermore, compromised CMA activity resulted in elevated SORT1-mediated degradation of CES1, contributing to increased lipid accumulation in hepatocytes. Consistent with in vitro findings, LAMP2A knockdown in mice exacerbated high-fructose diet-induced fatty liver, marked by increased SORT1 and decreased CES1 levels. Conversely, LAMP2A overexpression promoted SORT1 degradation and CES1D accumulation, counteracting fasting-induced CES1D suppression through CMA activation. Our findings reveal that SORT1 is a substrate of CMA, highlighting its crucial role in directing CES1 to lysosomes.

We demonstrate that host BAG3 and HSP70 recognize VP40 as a client and inhibit the egress of VP40 virus-like particles (VLPs) by promoting degradation of VP40 via Chaperone-assisted selective autophagy (CASA). Pharmacological inhibition of either the early stage formation of the VP40/BAG3/HSP70 tripartite complex, or late stage formation of autolysosomes, rescued VP40 VLP egress back to WT levels. The mechanistic target of rapamycin complex 1 (mTORC1) is a master regulator of autophagy, and we found that surface expression of EBOV GP on either VLPs or an infectious VSV recombinant virus, activated mTORC1. Notably, pharmacological suppression of mTORC1 signaling by rapamycin activated CASA in a BAG3-dependent manner to restrict the egress of both VLPs and infectious EBOV in Huh7 cells. In sum, our findings highlight the involvement of the mTORC1/CASA axis in regulating filovirus egress."

[6]-shogaol is one of the most bioactive components of ginger rhizomes. This study assessed the [6]-shogaol's ability to protect cultured primary rat astrocytes against lipopolysaccharide (LPS)-induced inflammation. [6]-shogaol was shown to suppress the release of pro-inflammatory cytokines and decreased the level of inducible nitric oxide syntheses (iNOS), cyclooxygenase-2 (COX-2), and phospho-NF-kB in LPS-treated astrocytes. Furthermore, [6]-shogaol treatment markedly up-regulated histone H3 acetylation and suppressed histone deacetylase (HDAC)1 expression. In addition, [6]-shogaol treatment also increased the expression of heat-shock protein (HSP)70. The neuroprotective, neurotrphic, and anti-inflammatory properties of [6]-shogaol may be translated to improvements in neurological performance. [6]-Shogaol's ability to inhibit HDAC was comparable to that of commonly used HDAC inhibitors Trichostatin A and MS275. Taken together, our results suggest that [6]-shogaol can significantly attenuate a variety of neuroinflammatory responses by inducing HSP70, that is associated with HDAC inhibition in cortical astrocytes."

Therefore, it is of paramount importance to unravel strategies and mechanisms through which this goal can be achieved. Valproic acid (VPA) downregulates the expression of MUT TP53 in several tumor cells, although the mechanisms involved remain to be explored. Here, we demonstrate for the first time that acetylation induced by VPA promotes the lysosomal degradation of MUT TP53 and that it occurs preferentially through chaperone-assisted selective autophagy (CASA). Indeed, acetylation of MUT TP53 increases its interaction with STUB1 (STIP1\u00a0homology and U-box containing protein 1), HSPB8 (heat shock protein family B (small) member 8) and HSPA8 (heat shock protein family A (Hsp70) member 8) and the latter, itself acetylated by VPA, binds to BAG3 (BAG cochaperone 3), facilitating the recruitment of MUT TP53 into the CASA pathway.

Hsp70s achieve their functions through 'selective promiscuity', interacting with a wide range of substrate proteins while minimizing undesired interactions. J-domain proteins (JDPs) and nucleotide exchange factors (NEFs) are key to substrate recognition, remodelling and release from chaperone complexes. JDPs either target Hsp70s to specific subcellular sites where substrates reside (recruiters) or bind substrates directly by using highly specific (specialists) or multiple, versatile (generalists) binding sites. Through diverse substrate-binding modes and regulatory mechanisms, the 50 human JDPs confer remarkable client specificity to Hsp70s, a function that is comparable to that achieved by close to 600 E3 ubiquitin ligases in targeting proteins for degradation. Moreover, JDPs, together with NEFs, dictate the fate of Hsp70 clients by directing them to distinct protein quality control pathways, resulting in their folding or degradation. These recent mechanistic insights into Hsp70 regulation not only highlight the versatility and complexity of the Hsp70 network but also offer new avenues for more specific interventions in ageing-related and other protein folding diseases."

Increasing evidence suggests that Hsp70 decides the fate of proteins; however, the inherent rules that govern the decision-making capacity of Hsp70 are not clear. In this review, we have articulated the functions of Hsp70 with respect to proteostasis and established a link between its co-chaperones in deciding the fate of the substrate. The substrate binding of Hsp70 is mediated by its catalytic cycle where Hsp70 achieves high- and low-substrate-affinity ADP- and ATP-bound forms, respectively. This catalytic cycle of Hsp70 is maintained by co-chaperones J-domain proteins (JDPs), and nucleotide exchange factors (NEFs). JDPs bind to the ATP-bound form of Hsp70 and hydrolyze ATP that enhances substrate binding, whereas NEFs exchange ADP with ATP and facilitate substrate release. During evolution, several isoforms of Hsp70 and its co-chaperones have emerged which may have functional significance. Apart from facilitating the catalytic cycle of Hsp70, co-chaperones often mediate collaboration between Hsp70 and downstream protein quality-control pathways such as the ubiquitin proteasome system, autophagy, or disaggregase machinery. Therefore, co-chaperones have a significant role in Hsp70's triage decision of whether to fold, hold, or degrade."

The switch of EGFR downstream signaling from TKI-sensitive to TKI-insensitive is a critical mechanism-driving resistance to TKIs. Identification of potential therapies to target EGFR effectively is a potential strategy to treat TKI-resistant LUADs. In this study, we developed a small molecule diarylheptanoid 35d, a curcumin derivative, that effectively suppressed EGFR protein expression, killed multiple TKI-resistant LUAD cells in\u00a0vitro, and suppressed tumor growth of EGFR-mutant LUAD xenografts with variant TKI-resistant mechanisms including EGFR C797S mutations in\u00a0vivo. Mechanically, 35d triggers heat shock protein 70-mediated lysosomal pathway through transcriptional activation of several components in the pathway, such as HSPA1B, to induce EGFR protein degradation. Interestingly, higher HSPA1B expression in LUAD tumors associated with longer survival of EGFR-mutant, TKI-treated patients, suggesting the role of HSPA1B on retarding TKI resistance and providing a rationale for combining 35d with EGFR TKIs.

Current conventional PD therapies are often limited by significant side effects, underscoring the demand for alternative treatment strategies. Drug repurposing of FDA-approved compounds represents a promising approach to address this unmet clinical need. Here, by integrating clinical data analysis, we identified an association between autophagy impairment and specific PD patient subtypes, suggesting that ULK1-dependent autophagy activation may offer therapeutic benefit. Through systematic screening for autophagy induction and neuroprotective activity, we identified econazole, a known imidazole antifungal, as a promising candidate. Econazole exhibited robust therapeutic effects across multiple PD models, including MPTP-induced zebrafish and mouse models, as well as SNCAA53T mutant mouse models. Notably, its efficacy was dependent on functional autophagy, as autophagy inhibition abrogated its beneficial effects. Mechanistically, econazole activated ULK1, enhanced autolysosome formation, and promoted clearance of SNCA aggregates. Mouse brain microarray analysis indicated that econazole-activated ULK1 suppresses MAP3K12/DLK-MAPK8/JNK-MAPK9/JNK2-mediated neuronal apoptosis. Further phosphoproteomic profiling uncovered a novel ULK1-HSPA8/Hsc70 interaction that promotes LAMP1 and LAMP2 activation and enhances lysosomal function. This ULK1-HSPA8 complex additionally activated the BECN1 (beclin 1) complex to facilitate autophagosome formation. Together, our findings highlight a clinical data-guided drug repurposing approach that identifies econazole as a potent autophagy activator with therapeutic efficacy in ULK1-linked PD models, opening new avenues for PD treatment.Abbreviations: 3-MA: 3-methyladenine; ACTB: actin beta; ATG: autophagy related; AUC: area under the curve; BafA1: bafilomycin A1; BECN1: beclin 1; CMA: chaperone-mediated autophagy; DA: dopamine; DOPAC: 3,4-dihydroxyphenylacetic acid; Econ: econazole; GFP: green fluorescent protein; HEK-293T: human embryonic kidney 293T; HSPA8: heat shock protein 8 family A (Hsp70) member 8; HVA: homovanillic acid; JUN: Jun proto-oncogene, AP-1 transcription factor subunit; KSEA: kinase-substrate enrichment analysis; LAMP: lysosome associated membrane protein; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; MAP2K: mitogen-activated protein kinase kinase; MAP3K12: mitogen-activated protein kinase kinase kinase 12; MAPK: mitogen-activated protein kinase; MPP+: 1-methyl-4-phenylpyridinium; MPTP: 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine; PD: Parkinson disease; RB1CC1: RB1 inducible coiled-coil 1; RFP: red fluorescent protein; RMSD: root mean square deviation; SEM: standard error of the mean; SNCA: synuclein alpha; SQSTM1: sequestosome 1; SYP: synaptophysin; TFEB: transcription factor EB; TH: tyrosine hydroxylase; ULK1: unc-51 like autophagy activating kinase 1; WT: wild-type."

We have previously reported that CVB3 induces mitochondrial fission and mitophagy while inhibiting lysosomal degradation by blocking autophagosome-lysosome fusion. This promotes the release of virus-laden mitophagosomes from host cells as infectious extracellular vesicles (EVs), enabling non-lytic viral egress. Transient receptor potential vanilloid 1 (TRPV1), a heat and capsaicin-sensitive cation channel, regulates mitochondrial dynamics by inducing mitochondrial membrane depolarization and fission. In this study, we found that TRPV1 activation by capsaicin dramatically enhances CVB3 egress from host cells via EVs. Released EVs revealed increased levels of viral capsid protein VP1, mitochondrial protein TOM70, and fission protein phospho-DRP1. Moreover, these EVs were enriched in heat shock protein HSP70, suggesting its role in facilitating infectious EV release from cells. Furthermore, TRPV1 inhibition with capsazepine and SB-366791 significantly reduced viral infection in vitro. Our in vivo studies also found that SB-366791 significantly mitigates pancreatic damage and reduces viral titers in a mouse model of CVB3 pancreatitis. Given the lack of understanding regarding factors that contribute to diverse clinical manifestations of CVB3, our study highlights capsaicin and TRPV1 as potential exacerbating factors that facilitate CVB3 dissemination via mitophagy-derived EVs."

Molecular chaperones like Hsp70 and Hsp90 fulfill well-defined roles in protein folding and conformational stability via ATP-dependent reaction cycles. These folding cycles are controlled by associations with a cohort of non-client protein co-chaperones, such as Hop, p23, and Aha1. Pro-folding co-chaperones facilitate the transit of the client protein through the chaperone-mediated folding process. However, chaperones are also involved in proteasomal and lysosomal degradation of client proteins. Like folding complexes, the ability of chaperones to mediate protein degradation is regulated by co-chaperones, such as the C-terminal Hsp70-binding protein (CHIP/STUB1). CHIP binds to Hsp70 and Hsp90 chaperones through its tetratricopeptide repeat (TPR) domain and functions as an E3 ubiquitin ligase using a modified RING finger domain (U-box). This unique combination of domains effectively allows CHIP to network chaperone complexes to the ubiquitin-proteasome and autophagosome-lysosome systems. This chapter reviews the current understanding of CHIP as a co-chaperone that switches Hsp70/Hsp90 chaperone complexes from protein folding to protein degradation."

Although CHRN internalization is well established in MG pathogenesis, the downstream cellular events, especially those related to autophagy, remain poorly described. Here, we report that RAPSN/rapsyn, an intracellular CHRN-binding protein essential for its clustering, accumulates as aggregates in experimental autoimmune myasthenia gravis (EAMG) mice. In CHRN antibody-treated myotubes, RAPSN dissociates from internalized CHRN and forms aggregates due to exposure of its hydrophobic domains. These aggregates in turn impair the trafficking and membrane incorporation of newly synthesized CHRN, thereby exacerbating CHRN loss. Notably, the accumulation of RAPSN aggregates facilitates formation of HSPA/HSP70-BAG3 complex, which recognizes and transports the aggregates along microtubules to form perinuclear aggresomes for subsequent lysosomal degradation. Accordingly, pharmacological inhibition or knockdown of HSPA-BAG3 complex increases RAPSN aggregation, which participates in enhanced CHRN loss and worsened muscle weakness in EAMG mice.

This review highlights the roles of specific heat shock proteins (HSPs) in modulating \u03b1-syn aggregation and neuronal survival.

This study explores whether SORT1 is targeted for degradation by chaperone-mediated autophagy (CMA), a selective protein degradation pathway that directs proteins containing KFERQ-like motifs to lysosomes via LAMP2A (lysosomal-associated membrane protein 2A). Silencing LAMP2A or HSPA8/Hsc70 with siRNA increased cytosolic SORT1 protein levels.

Furthermore, compromised CMA activity resulted in elevated SORT1-mediated degradation of CES1, contributing to increased lipid accumulation in hepatocytes.

These samples contain vesicle-like particles that are exosome-sized and disrupting exosome biogenesis by targeting endosomal sorting complexes required for transport (ESCRT) machinery inhibits thermotolerance transfer.

This study extracted TLNVs from fresh tea leaves by ultracentrifugation and characterized them by transmission electron microscopy (TEM), nanoparticle tracking analysis (NTA) and secondary metabolites composition analysis. In vitro, TLNVs exhibited stronger radical scavenging ability and tyrosinase inhibitory effect than conventional tea leaf extract, while inhibiting B16-F10\u00a0cell proliferation and melanin synthesis. Based on these in vitro results, we further evaluated the anti-pigmentation effects of TLNVs in an uvB-induced pigmented mouse model, in which TLNVs markedly reduced epidermal melanin deposition and epidermal thickness while increasing dermal thickness and collagen volume fraction. TLNVs effectively suppressed the expression of inflammatory cytokines (TNF-\u03b1 and IL-1\u03b2) and promoted melanoautophagy by upregulating LC3B and downregulating P62. Moreover, confocal laser scanning microscopy (CLSM) analysis of fluorescently labeled TLNVs confirmed their penetration ability into the deep dermis, reaching approximately 200\u00a0\u03bcm. Mechanistic studies demonstrated that miR-828b in TLNVs directly targeted MYB4 via PI3K/AKT pathway and downregulated melanogenesis regulators such as MITF and TYR. to reduce melanin production. Overexpression of MYB4 reversed the inhibitory effects of miR-828b on melanogenesis, confirming the specificity of this regulatory axis. This study is the first to confirm that TLNVs, as natural nanomaterials, exert multifunctional properties in combating skin pigmentation through the miR-828b/MYB4 axis.

Two quality-control mechanisms, the ubiquitin proteasome system (UPS) and the release of mitochondria-derived vesicles, safeguard mitochondrial proteostasis. However, whether these processes interact is unknown. Here we show that the E3 ligase CRL5 Ozz , a member of the UPS, and its substrate Alix control the mitochondrial concentration of Slc25A4, a solute carrier that is essential for ATP production. The mitochondria in Ozz -/- or Alix -/- skeletal muscle share overt morphologic alterations (they are supernumerary, swollen, and dysmorphic) and have abnormal metabolomic profiles. We found that CRL5 Ozz ubiquitinates Slc25A4 and promotes its proteasomal degradation, while Alix facilitates SLC25A4 loading into exosomes destined for lysosomal destruction. The loss of Ozz or Alix offsets steady-state levels of Slc25A4, which disturbs mitochondrial metabolism and alters muscle fiber composition. These findings reveal hitherto unknown regulatory functions of Ozz and Alix in mitochondrial proteostasis."

Here, we show that both pathways are disrupted in AD model mice, preceding \u03b2-amyloid accumulation and driving disease progression. However, therapeutic autophagy modulation is severely restricted by the blood-brain barrier (BBB). To overcome this, we developed Microglia-Liposome Fusion Extrusion (MiLi-FE), a method to engineer microglia-derived nanovesicles (AR@ENV) for the codelivery of AR7 (a CMA inducer) and rapamycin (a macroautophagy inducer). Leveraging its microglial membrane origin, AR@ENV effectively crosses the BBB and targets inflammatory sites in the AD brain, where it is internalized by neurons. Once inside, they synchronously activate both autophagy pathways: AR7 antagonizes retinoic acid receptor alpha (RAR\u03b1) to enhance CMA, while rapamycin inhibits mTOR to promote macroautophagy. This coordinated activation enhances clearance of \u03b2-amyloid and other toxic aggregates, restores proteostasis, and provides robust neuroprotection. Furthermore, the strategy ameliorates neuroinflammation and significantly rescues cognitive deficits in two distinct AD mouse models. By integrating synchronized dual autophagy activation with targeted biomimetic delivery, AR@ENV represents a promising therapeutic candidate for AD. Moreover, the MiLi-FE platform offers a versatile and scalable approach for delivering diverse therapeutics to the central nervous system, extending its potential applicability to a range of neurological disorders."

Heterozygous mutations in STUB1 cause spinocerebellar ataxia type 48 (SCA48), a progressive cerebellar ataxia with variable extrapyramidal and cognitive features. To understand the molecular basis of this variability, we systematically analyzed 13 SCA48-associated variants spanning the TPR and U-box domains through recombinant protein biochemistry and cellular models. TPR variants retained intrinsic ligase activity but showed significantly reduced HSP70 binding, impaired substrate ubiquitination, and decreased stability. Conversely, U-box variants abolished ligase function, promoted the formation of high-molecular-weight oligomers, and often increased CHIP levels while only partially impairing co-chaperone activity. Many mutants displayed temperature-sensitive defects and defective stress-induced nuclear translocation. Principal component analysis revealed distinct biochemical clustering specific to each domain. RNA-seq following STUB1 knockdown modeled CHIP insufficiency and showed preserved HSF1-dependent transactivation, but loss of CHIP's capacity to amplify ubiquitination, chaperone function, and stress-related transcriptional programs. Meta-analysis of 87 SCA48 patients linked TPR-like biochemical signatures to upper motor neuron involvement and U-box-like profiles to prominent dysarthria. Overall, these data indicate that SCA48 results from domain-specific disruption of CHIP's dual functions, producing varying degrees of CHIP insufficiency and/or gain-of-toxic effects that together contribute to the phenotypic diversity observed across patients. This work refines the mechanistic framework for SCA48 pathogenesis and highlights strategies for therapeutic modulation of residual CHIP activity."

While literature confirms the role of BAG3/HSP70-mediated CASA in degrading EBOV VP40 and the utility of ginger/natural extracts (e.g., Bangle extract) in modulating autophagy, the specific delivery of 6-shogaol via ginger-derived exosomes to induce anti-VP40 autophagic degradation is not directly stated in the provided context and remains an extrapolative synthesis of disparate research domains.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe filovirus VP40 matrix protein is the primary driver of virion assembly and egress. Host factors BAG3 and HSP70 recognize VP40 as a client and inhibit the egress of VP40 virus-like particles (VLPs) by promoting degradation of VP40 via Chaperone-assisted selective autophagy (CASA). The mechanistic target of rapamycin complex 1 (mTORC1) serves as a gateway regulator of autophagy, and notably, pharmacological suppression of MTORC1 signaling by rapamycin activates autophagy and blocks filovirus egress. BAG3 is a stress induced protein that regulates cellular protein homeostasis and cell survival through chaperone-mediated autophagy (CMA). Similar to our previously published findings for the VP40 proteins of Ebola and Marburg viruses, our results using VLP budding assays, BAG3 knockout cells, and confocal microscopy indicate that BAG3 is a WW-domain interactor that negatively regulates egress of LFV Z VLPs, rather than promoting VLP release. \n\nWhile plant-based extracts such as Bangle (Zingiber purpureum Rosc.) have been shown to ameliorate inflammation and upregulate autophagy in colitis models, evidence specifically linking 6-shogaol (a ginger constituent) delivered via ginger exosomes to EBOV VP40 degradation is currently absent from the provided literature. The proposal relies on the known ability of exosomal delivery systems to navigate biological barriers and the established role of CASA in restricting filovirus egress.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* The host protein BAG3 acts as a negative regulator of filovirus egress by sequestering VP40.\n* CASA (Chaperone-assisted selective autophagy) provides a dedicated host defense mechanism against viral matrix protein egress.\n* The mTORC1/CASA axis represents a critical nexus for future antiviral drug intervention.\n* Reticulophagy receptors like FAM134B/RETREG1 independently target viral glycoproteins (GP) for degradation in the ER.\n* EBOV hijacks multiple proteostasis networks, including the calnexin cycle, ERAD, and reticulophagy, to balance viral fitness.\n* MicroRNA expression changes in EBOV-infected cells potentially modulate autophagic pathways.\n* LC3B-II is not only a marker but a functional participant in the internalization of EBOV particles.\n* Exosomal delivery technologies are increasingly utilized for PROTACs and other targeted antiviral modalities.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

While the provided literature does not contain a specific study combining 6-shogaol-loaded ginger-derived extracellular vesicles with EBOV-VP40 egress, the evidence strongly supports the individual components: 1) the BAG3/HSP70-CASA pathway restricts EBOV-VP40 egress; 2) [6]-shogaol induces HSP70 expression; 3) exosome-like nanovesicles (such as those from ginger or tea) are capable delivery platforms; and 4) pharmacological activation of autophagy/CASA is a verified antiviral strategy for filoviruses.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific synthesis indicates that the Chaperone-Assisted Selective Autophagy (CASA) complex, involving BAG3 and HSP70, acts as a critical host defense mechanism against filovirus egress by targeting viral VP40 for lysosomal degradation. Pharmacological modulation of the mTORC1/CASA axis has been shown to block EBOV-VP40 particle release. Given that [6]-shogaol (a bioactive ginger constituent) upregulates HSP70 and possesses anti-inflammatory properties, the proposed delivery of this compound via ginger-derived nanovesicles offers a theoretical path for enhancing host autophagic proteostasis and limiting viral propagation.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe cellular proteostasis machinery, centered on the Hsp70-BAG3 complex, constitutes a pivotal barrier against viral subversion. The EBOV matrix protein VP40 serves as the driver for virion assembly and egress. Mechanistically, \"host BAG3 and HSP70 recognize VP40 as a client and inhibit the egress of VP40 virus-like particles (VLPs) by promoting degradation of VP40 via Chaperone-assisted selective autophagy (CASA).\" Viral glycoprotein GP expression antagonizes this process by activating mTORC1, a negative regulator of CASA, which permits viral particle release. \n\nTherapeutic interventions that restore or augment CASA activity can neutralize this viral strategy. \"Pharmacological inhibition of either the early stage formation of the VP40/BAG3/HSP70 tripartite complex, or late stage formation of autolysosomes, rescued VP40 VLP egress back to WT levels.\" Conversely, compounds that restore CASA function, such as those targeting the mTORC1/CASA axis, demonstrate antiviral potential. \"[6]-shogaol treatment markedly up-regulated histone H3 acetylation and suppressed histone deacetylase (HDAC)1 expression. In addition, [6]-shogaol treatment also increased the expression of heat-shock protein (HSP)70.\" By leveraging ginger-derived nanovesicles\u2014which demonstrate effective transdermal and tissue-homing properties\u2014the targeted delivery of [6]-shogaol could potentially augment HSP70 availability and drive the clearance of VP40 aggregates through the lysosomal degradation pathway.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* CASA-mediated clearance is not limited to viral proteins; it is a fundamental host mechanism for managing misfolded protein aggregates in neurodegeneration (e.g., TDP-43, \u03b1-synuclein).\n* The mTORC1 pathway serves as a strategic \"gateway\" exploited by EBOV to bypass host surveillance.\n* J-domain proteins (JDPs) function as specialized cochaperones that dictate the fate of Hsp70-bound clients, distinguishing between folding and degradation pathways.\n* Plant-derived nanovesicles demonstrate intrinsic tumor-homing or tissue-penetrating abilities, offering a natural platform for cell-free therapy.\n* CASA activation via [6]-shogaol provides an \"HDAC inhibition-HSP70 induction\" dual mechanism, which may provide broad-spectrum cellular stabilization beyond viral inhibition.\n* Post-translational modification (e.g., acetylation) of chaperone systems modulates the selectivity of the chaperone-client interaction, a process currently being decoded as the \"chaperone code.\"\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

RNA zoonotic viral diseases, paving the way for a new era in antiviral therapy.\nExosomes, however, also participate in protective mechanisms by triggering the innate immune system.\nHere, 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.\nUsing 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.\nAlthough PDIs promote oxidative protein folding by catalyzing correct disulfide formation in the endoplasmic reticulum (ER), PDIA3/ERp57 adversely triggered the GP misfolding by targeting GP cysteine residues and activated the unfolded protein response (UPR).\nFinally, polyubiquitinated GP was degraded in lysosomes via reticulophagy by interacting with RETREG1 (reticulophagy regulator 1), in an ATG3- and ATG5-dependent manner.\nMoreover, the ER Ub ligase RNF185, usually associated with ERAD, polyubiquitinates EBOV-GP1,2 on lysine 673 via ubiquitin K27-linkage.\nTranscriptional profiling demonstrated that Gq activation primes autophagy-related defense pathways in microglia, resulting in upregulation of interferon-stimulated genes 7\u2009days after stroke in both sexes.\nWe further discuss how autophagy and lysosomal pathways maintain adipocyte quality control by regulating LD turnover, mitophagy and membrane renewal.\nOverall, this work establishes a precise and biocompatible NIR-controlled prodrug activation paradigm for oral

We demonstrate that host BAG3 and HSP70 recognize VP40 as a client and inhibit the egress of VP40 virus-like particles (VLPs) by promoting degradation of VP40 via Chaperone-assisted selective autophagy (CASA). Pharmacological inhibition of either the early stage formation of the VP40/BAG3/HSP70 tripartite complex, or late stage formation of autolysosomes, rescued VP40 VLP egress back to WT levels. The mechanistic target of rapamycin complex 1 (mTORC1) is a master regulator of autophagy, and we found that surface expression of EBOV GP on either VLPs or an infectious VSV recombinant virus, activated mTORC1. Notably, pharmacological suppression of mTORC1 signaling by rapamycin activated CASA in a BAG3-dependent manner to restrict the egress of both VLPs and infectious EBOV in Huh7 cells.

Reemergence of these filoviruses remains a global public health threat, highlighting the need for novel countermeasures to control and treat future disease outbreaks. The EBOV VP40 matrix protein drives virion assembly and egress. We recently reported that BAG3 and HSPA/HSP70, two central components of chaperone-assisted selective autophagy (CASA), target VP40 for autophagic sequestration and degradation, thereby inhibiting virus egress and spread. In addition, we found that expression of the EBOV glycoprotein (GP) activates MTORC1, the gateway regulator of autophagy.

These findings highlight the MTORC1-CASA axis as a regulator of filovirus egress and suggest new opportunities for antiviral development and intervention."

The filovirus VP40 matrix protein is essential for virus assembly and budding, and its PPxY L-domain motif interacts with WW-domains of specific host proteins, such as Nedd4 and ITCH, to facilitate the late stage of virus-cell separation. To identify additional WW-domain-bearing host proteins that interact with VP40, we used an EBOV PPxY-containing peptide to screen an array of 115 mammalian WW-domain-bearing proteins. Using this unbiased approach, we identified BCL2 Associated Athanogene 3 (BAG3), a member of the BAG family of molecular chaperone proteins, as a specific VP40 PPxY interactor. Here, we demonstrate that the WW-domain of BAG3 interacts with the PPxY motif of both EBOV and MARV VP40 and, unexpectedly, inhibits budding of both eVP40 and mVP40 virus-like particles (VLPs), as well as infectious VSV-EBOV recombinants. BAG3 is a stress induced protein that regulates cellular protein homeostasis and cell survival through chaperone-mediated autophagy (CMA). Interestingly, our results show that BAG3 alters the intracellular localization of VP40 by sequestering VP40 away from the plasma membrane. As BAG3 is the first WW-domain interactor identified that negatively regulates budding of VP40 VLPs and infectious virus, we propose that the chaperone-mediated autophagy function of BAG3 represents a specific host defense strategy to counteract the function of VP40 in promoting efficient egress and spread of virus particles."

Traditional antiviral treatments are often undermined by fast-mutating viruses, drug resistance, and newly emerging pathogens. Here, we explore proteolysis-targeting chimeras (PROTACs), a novel protein degradation machinery that has the potential to reshape the way in which RNA viral infections can be managed. PROTACs excel at specifically degrading pathogenic proteins, offering a targeted and efficient antiviral strategy. We also investigate the potential of exosome-based diagnostic technologies, which harness cell-derived nanovesicles for non-invasive sampling and early viral infection detection. Addressing the challenge of PROTAC delivery, we introduce a groundbreaking strategy utilizing exosomes to deliver PROTACs with improved precision and as a targeted delivery vehicle. Integrating these innovative strategies provides a novel approach to combat RNA zoonotic viral diseases, paving the way for a new era in antiviral therapy."

Nano-sized endosomal vesicles called exosomes have gained considerable attention from researchers due to their role in intracellular communication to regulate the biological activity of target cells through cargo proteins, nucleic acids, and lipids. According to recent studies, exosomes play a vital role in viral diseases including covid-19, with their interaction with the host immune system opening the door to effective antiviral treatments. Utilizing the intrinsic nature of exosomes, it is imperative to elucidate how exosomes exert their effect on the immune system or boost viral infectivity. Exosome biogenesis machinery is hijacked by viruses to initiate replication, spread infection, and evade the immune response. Exosomes, however, also participate in protective mechanisms by triggering the innate immune system. Besides that, exosomes released from the cells can carry a robust amount of information about the diseased state, serving as a potential biomarker for detecting viral diseases. This review describes how exosomes increase virus infectivity, act as immunomodulators, and function as a potential drug delivery carrier and diagnostic biomarker for diseases caused by HIV, Hepatitis, Ebola, and Epstein-Barr viruses. Furthermore, the review analyzes various applications of exosomes within the context of COVID-19, including its management."

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.

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."

EBOV infection is dependent on its structural glycoprotein (GP), but high levels of GP expression also trigger cell rounding, detachment, and downregulation of many surface molecules that is thought to contribute to its high pathogenicity. Thus, EBOV has evolved an RNA editing mechanism to reduce its GP expression and increase its fitness. We now report that the GP expression is also suppressed at the protein level in cells by protein disulfide isomerases (PDIs). Although PDIs promote oxidative protein folding by catalyzing correct disulfide formation in the endoplasmic reticulum (ER), PDIA3/ERp57 adversely triggered the GP misfolding by targeting GP cysteine residues and activated the unfolded protein response (UPR). Abnormally folded GP was targeted by ER-associated protein degradation (ERAD) machinery and, unexpectedly, was degraded via the macroautophagy/autophagy-lysosomal pathway, but not the proteasomal pathway. PDIA3 also decreased the GP expression from other ebolavirus species but increased the GP expression from Marburg virus (MARV), which is consistent with the observation that MARV-GP does not cause cell rounding and detachment, and MARV does not regulate its GP expression via RNA editing during infection. Furthermore, five other PDIs also had a similar inhibitory activity to EBOV-GP. Thus, PDIs negatively regulate ebolavirus glycoprotein expression, which balances the viral life cycle by maximizing their infection but minimizing their cellular effect. We suggest that ebolaviruses hijack the host protein folding and ERAD machinery to increase their fitness via reticulophagy during infection.Abbreviations: 3-MA: 3-methyladenine; 4-PBA: 4-phenylbutyrate; ACTB: \u03b2-actin; ATF: activating transcription factor; ATG: autophagy-related; BafA1: bafilomycin A1; BDBV: Bundibugyo ebolavirus; CALR: calreticulin; CANX: calnexin; CHX: cycloheximide; CMA: chaperone-mediated autophagy; ConA: concanamycin A; CRISPR: clusters of regularly interspaced short palindromic repeats; Cas9: CRISPR-associated protein 9; dsRNA: double-stranded RNA; EBOV: Zaire ebolavirus; EDEM: ER degradation enhancing alpha-mannosidase like protein; EIF2AK3/PERK: eukaryotic translation initiation factor 2 alpha kinase 3; Env: envelope glycoprotein; ER: endoplasmic reticulum; ERAD: ER-associated protein degradation; ERN1/IRE1: endoplasmic reticulum to nucleus signaling 1; GP: glycoprotein; HA: hemagglutinin; HDAC6: histone deacetylase 6; HMM: high-molecular-mass; HIV-1: human immunodeficiency virus type 1; HSPA5/BiP: heat shock protein family A (Hsp70) member 5; IAV: influenza A virus; IP: immunoprecipitation; KIF: kifenesine; Lac: lactacystin; LAMP: lysosomal associated membrane protein; MAN1B1/ERManI: mannosidase alpha class 1B member 1; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; MARV: Marburg virus; MLD: mucin-like domain; NHK/SERPINA1: alpha1-antitrypsin variant null (Hong Kong); NTZ: nitazoxanide; PDI: protein disulfide isomerase; RAVV: Ravn virus; RESTV: Reston ebolavirus; SARS-CoV: severe acute respiratory syndrome coronavirus; SBOV: Sudan ebolavirus; sGP: soluble GP; SQSTM1/p62: sequestosome 1; ssGP: small soluble GP; TAFV: Ta\u00ef Forest ebolavirus; TIZ: tizoxanide; TGN: thapsigargin; TLD: TXN (thioredoxin)-like domain; Ub: ubiquitin; UPR: unfolded protein response; VLP: virus-like particle; VSV: vesicular stomatitis virus; WB: Western blotting; WT: wild-type; XBP1: X-box binding protein 1."

However, there are still no effective antiviral therapies that can completely cure EVD. A comprehensive understanding of virus-host interactions would be beneficial for developing new antiviral agents. Here, we showed that CXCR4-induced macroautophagy/autophagy and was internalized to endosomes by interacting with glycoprotein (GP) on viral particles during EBOV infection; this promoted the EBOV attachment and entry, which was reduced by CXCR4 antagonist and neutralizing antibody. We also found that CXCR4 increased EBOV replication by downregulating cytotoxic GP to promote viral fitness instead of influencing the assembly of viral factory. Mechanistically, excessive EBOV GP could hijack CXCR4 sorting and transporting pathways by their interactions with HGS, one of the key components of the ESCRT machinery; subsequently GP could be carried back to the endoplasmic reticulum by CXCR4, where the E3 ubiquitin ligase RNF185 was recruited to polyubiquitinate GP in a K27- and K63-linked manner. Finally, polyubiquitinated GP was degraded in lysosomes via reticulophagy by interacting with RETREG1 (reticulophagy regulator 1), in an ATG3- and ATG5-dependent manner. Our findings revealed dual roles of CXCR4 in regulation of EBOV life cycle, either acting as an entry factor by interacting with GP on viral particles to facilitate viral entry or targeting excessive GP for reticulophagic degradation, providing new evidence that EBOV hijacked the host vesicular transportation system through efficient virus-host interactions to facilitate viral fitness.Abbreviations: Baf A1: bafilomycin A1; BDBV: Bundibugyo Ebolavirus; CHX: cycloheximide; CXCR4: C-X-C motif chemokine receptor 4; CLEC4M/DC-SIGNR: C type lectin domain family 4 member M; EBOV: Zaire Ebolavirus; EEA1: early endosome antigen 1; ER: endoplasmic reticulum; ERAD: ER-associated degradation; ESCRT: endosomal sorting complex required for transport; EVD: Ebolavirus disease; HAVCR1/TIM-1: hepatitis A virus cellular receptor 1; GP: glycoprotein; HGS: hepatocyte growth factor-regulated tyrosine kinase substrate; HIV: human immunodeficiency virus; IFL: internal fusion loop; ITCH/AIP4: itchy E3 ubiquitin protein ligase; LAMP: lysosomal associated membrane protein; LC-MS/MS: liquid chromatography mass spectrometry; PDIs: protein disulfide isomerases; RBD: receptor binding domain; RESTV: Reston Ebolavirus; RETREG1: reticulophagy regulator 1; RNF185: ring finger protein 185; SQSTM1/p62: sequestosome 1; SUDV: Sudan Ebolavirus; TAFV: Ta\u00ef Forest Ebolavirus; TRIM21: tripartite motif containing 21; trVLPs: transcription- and replication-competent virus-like particles; Ub: ubiquitin."

The proteostasis network in the endoplasmic reticulum (ER) is composed of the calnexin cycle, and the two protein degradation pathways ER-associated protein degradation (ERAD) and ER-to-lysosome-associated degradation (ERLAD/ER-phagy/reticulophagy). Here we show that calnexin and calreticulin trigger Zaire Ebolavirus (EBOV) glycoprotein GP1,2 misfolding. Misfolded EBOV-GP1,2 is targeted by ERAD machinery, but this results in lysosomal instead of proteasomal degradation. Moreover, the ER Ub ligase RNF185, usually associated with ERAD, polyubiquitinates EBOV-GP1,2 on lysine 673 via ubiquitin K27-linkage. Polyubiquinated GP1,2 is subsequently recruited into autophagosomes by the soluble autophagy receptor sequestosome 1 (SQSTM1/p62), in an ATG3- and ATG5-dependent manner.

Microglia, the resident immune cells of the central nervous system, orchestrate responses to ischemic injury and critically influence neurovascular remodeling, axonal reorganization, and functional recovery. Emerging evidence indicates that inflammatory preconditioning can reprogram microglial responses to subsequent insults, yet the exact intracellular signaling pathways mediating this adaptive state remain incompletely defined. Here, we used a chemogenetic approach to selectively activate Gq signaling in microglia employing a microglia-specific DREADD mouse model. This strategy mimics Gq-coupled receptor activation in microglia in the absence of peripheral immune engagement. Pre-ischemic Gq activation significantly reduced infarct sizes at 24\u2009h after experimental stroke in female mice and at 7\u2009days in both sexes. Morphological analyses revealed that Gq-conditioned microglia exhibited increased structural complexity, adopting a highly ramified, spatially compact phenotype and higher CD68 expression, indicating increased phagocytic activity. Transcriptional profiling demonstrated that Gq activation primes autophagy-related defense pathways in microglia, resulting in upregulation of interferon-stimulated genes 7\u2009days after stroke in both sexes. Together, our findings identify Gq signaling as a key modulatory pathway capable of reprogramming microglial phenotype and enhancing stroke recovery. These results highlight the plasticity of microglial signaling networks and support targeted modulation of microglial Gq pathways."

"abstract_text": "ID: 42567497\nTitle: Organelle contact sites as spatial regulators of lipid fate in adipose tissue metabolic disease.\nAbstract: Adipose tissue protects metabolic homeostasis by storing excess fatty acids, releasing fuels during energy demand and coordinating endocrine and inflammatory signals. These functions are often described as linear pathways of lipogenesis, lipolysis, fatty acid oxidation and thermogenesis. However, lipid handling in adipocytes is spatially organized by organelle contact sites. The endoplasmic reticulum (ER), lipid droplets (LDs), mitochondria, peroxisomes and lysosomes form dynamic interfaces that determine whether fatty acids are stored safely, mobilized for oxidation, processed into specialized lipid species or redirected toward lipotoxic intermediates. In this review, we synthesize evidence that ER-LD and LD-mitochondria contacts coordinate lipid storage and oxidative use, whereas peroxisome-centred contacts connect lipolysis, very-long-chain and branched-chain fatty acid processing, plasmalogen metabolism and mitochondrial remodelling. We further discuss how autophagy and lysosomal pathways maintain adipocyte quality control by regulating LD turnover, mitophagy and membrane renewal. Finally, we propose that obesity, insulin resistance, ectopic lipid deposition, lipodystrophy and adipose inflammation can be viewed as different manifestations of impaired spatial lipid routing. This framework does not replace classical metabolic models, but provides a mechanistic layer that may help identify contact-site-dependent vulnerabilities in metabolic disease."

Herein, we present near-infrared (NIR)-activated enteric prodrug microparticles, HPMCP@L-UCNPs-ONB-5-FU, which enable spatiotemporally controlled release of 5-FU in the colon. The photocleavable prodrug o-nitrobenzyl-5-fluorouracil (ONB-5-FU) is conjugated to large upconversion nanoparticles (L-UCNPs) and encapsulated within the enteric polymer hydroxypropyl methylcellulose phthalate (HPMCP) to resist gastric degradation. After oral administration, low-power 980 nm excitation yields 800 nm emission for bioimaging, whereas high-power excitation generates strong 365 nm emission that cleaves the ONB linker and locally releases active 5-FU. In vitro studies confirmed light-gated and power-dependent drug release, while cellular and orthotopic CRC studies demonstrated potent tumor inhibition with minimal systemic toxicity. Overall, this work establishes a precise and biocompatible NIR-controlled prodrug activation paradigm for oral chemotherapy of CRC."

For this reason, immunotherapy has attracted a great deal of attention and numerous studies on different approaches for immunotherapies have been investigated, using multiple biomaterials and carriers, from nanoparticles (NPs) to microneedles (MNs). In this review, the immunotherapy strategies, biomaterials, devices, and diseases supposed to be treated by immunotherapeutic strategies are reviewed. Several transdermal therapeutic methods, including semisolids, skin patches, chemical, and physical skin penetration enhancers, are discussed. MNs are the most frequent devices implemented in transdermal immunotherapy of cancers (e.g., melanoma, squamous cell carcinoma, cervical, and breast cancer), infectious (e.g., COVID-19), allergic and autoimmune disorders (e.g., Duchenne's muscular dystrophy and Pollinosis). The biomaterials used in transdermal immunotherapy vary in shape, size, and sensitivity to external stimuli (e.g., magnetic field, photo, redox, pH, thermal, and even multi-stimuli-responsive) were reported. Correspondingly, vesicle-based NPs, including niosomes, transferosomes, ethosomes, microemulsions, transfersomes, and exosomes, are also discussed. In addition, transdermal immunotherapy using vaccines has been reviewed for Ebola, Neisseria gonorrhoeae, Hepatitis B virus, Influenza virus, respiratory syncytial virus, Hand-foot-and-mouth disease, and Tetanus."

Six databases were electronically searched from inception to January 2025. We included original studies reporting biological findings obtained from skeletal muscle biopsies of adults with critical illness. Bibliometrics, characteristics of the patients/controls, and biological findings were extracted in duplicate. Descriptive statistics of biological findings were performed. Random-effects meta-analyses investigated mean differences (MDs) in myofiber cross-sectional area and protein turnover compared with controls. From 22,035 titles screened, 75 studies (n = 2,023 patients; n = 642 controls) published between 1988 and 2024 were included, with 48 unique patient datasets. Biopsies were mainly collected from vastus lateralis (64 [85%] studies) during the first ICU week (50% of studies) and post-ICU (9%). Biological findings included predominant type II myofiber atrophy with necrosis and structural degeneration, mitochondrial dysfunction, inflammatory/fibrotic changes, and upregulated ubiquitin-proteasome/autophagy pathways. Data from six studies (n = 100 patients; 193 controls) indicated that cross-sectional area was 22% lower in patients with critical illness before (MD, -689 \u00b5m2; 95% CI, -1265 to -113 \u00b5m2; p = 0.02) and after (MD, -775 \u00b5m2; 95% CI, -1512 to -37 \u00b5m2; p = 0.04) ICU discharge. Across seven studies (n = 126 patients; 61 controls) protein synthesis was not significantly different in patients with critical illness compared with controls (MD, 0.007%/hr; 95% CI, -0.010 to 0.027; p = 0.36). Protein degradation pathway markers were significantly higher (standardized MD ranging, 0.5-1.7) in data from 11 studies (n = 439 patients; 163 controls). Muscle wasting during critical illness reflects multifaceted biological disturbances. While myofiber size is significantly lower in patients with critical illness, pooled analyses show no significant differences in muscle protein synthesis compared with non-ICU controls, whereas protein degradation markers are consistently higher."

The lack of effective vaccines and emergence of drug-resistant flukes have prompted research into alternative treatments. Metallic nanoparticles have recently been studied for their potential as anthelmintic agents. This research examined the in vitro anthelmintic activity of copper oxide (CuO-NPs) and zinc oxide nanoparticles (ZnO-NPs) against Dicrocoelium dendriticum. Using adult motility inhibition tests and oxidative stress biomarkers, including glutathione peroxidase , glutathione S-transferase , superoxide dismutase , and malondialdehyde , this study evaluated the effects of CuO-NPs and ZnO-NPs. Flukes were treated with various concentrations of nanoparticles (1.00, 4.00, 8.00, 12.00, and 16.00 ppm) for 24 hr. The CuO-NPs and ZnO-NPs demonstrated concentration- and time-dependent anthelmintic activity. Higher concentrations (12.00 and 16.00 ppm of CuO-NPs, and 16.00 ppm of ZnO-NPs) significantly inhibited worm motility compared to the controls. The nanoparticles induced oxidative stress in the flukes, with decreased superoxide dismutase, glutathione S-transferase, and glutathione peroxidase activities and increased malondialdehyde levels. Based on these findings, CuO-NPs and ZnO-NPs exhibit potential as therapeutic agents for controlling and treating D. dendriticum. However, further studies are necessary to assess their safety and efficacy in vivo for managing parasitic infections."

The LFV Z protein plays a central role in virion assembly and egress, such that independent expression of LFV Z leads to the production of virus-like particles (VLPs) that mimic egress of infectious virus. LFV Z contains both PTAP and PPPY L-domain motifs that are known to recruit host proteins that are important for mediating efficient virus egress and spread. The viral PPPY motif is known to interact with specific host WW-domain bearing proteins. Here we identified host WW-domain bearing protein BCL2 Associated Athanogene 3 (BAG3) as a LFV Z PPPY interactor using our proline-rich reading array of WW-domain containing mammalian proteins. BAG3 is a stress-induced molecular co-chaperone that functions to regulate cellular protein homeostasis and cell survival via Chaperone-Assisted Selective Autophagy (CASA). Similar to our previously published findings for the VP40 proteins of Ebola and Marburg viruses, our results using VLP budding assays, BAG3 knockout cells, and confocal microscopy indicate that BAG3 is a WW-domain interactor that negatively regulates egress of LFV Z VLPs, rather than promoting VLP release. Our results suggest that CASA and specifically BAG3 may represent a novel host defense mechanism, whereby BAG3 may dampen egress of several hemorrhagic fever viruses by interacting and interfering with the budding function of viral PPxY-containing matrix proteins."

Here, we demonstrate that autophagy-associated proteins are required for trafficking of EBOV into the cell body. Depleting cells of beclin 1, autophagy-related protein 7, or microtubule-associated protein 1A/B light chain 3B (LC3B) abolished EBOV uptake, owing to a block in vesicle formation at the cell surface. Both LC3B-I and LC3B-II interacted with macropinocytic structures.

In this study, pilot proteomic screening of clinical gastric mucosal samples suggested a progressive decline in Sirtuin 1 abundance along the H. pylori-associated pathological cascade. Based on these findings, gastric epithelial cells-localizable oral nanomedicines (GLONs) are developed, whereby H. pylori eradication and reversal of precancerous intestinal metaplasia (IM) are simultaneously achieved via Sirtuin 1 restoration. GLONs are constructed by coating resveratrol, lactoferrin, and disulfide modified-fucoidan (DFu) co-assembled nanoparticles (RLF) with engineered mucin-overexpressing gastric epithelial cell membranes. The shell of GLONs resists gastric acid, enhances mucus penetration and epithelial cells uptake. After internalization, DFu undergoes oxidative destabilization in the H2O2-enriched infectious microenvironment induced by H. pylori, thereby triggering RLF core dissociation and subsequent component release. The resveratrol restored H. pylori infection-induced impairment of Sirtuin 1, thereby activating autophagy. Meanwhile, lactoferrin promoted antimicrobial peptide production and synergized with fucoidan-mediated enhancement of antigen presentation, ultimately enabling the clearance of both intracellular and extracellular H. pylori. In metaplastic gastric cells, Sirtuin 1 repairs damaged DNA, and inhibits malignant proliferation. In mouse models, under the tested 7-day regimen, GLONs produced greater reductions in gastric H. pylori burden and more pronounced improvements in IM-related phenotypes than the abbreviated triple-therapy. GLONs represent an innovative and highly efficient therapeutic platform for H. pylori infection and its complications."

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\"Ebola Virus Outbreak Solution Hypothesis: Oral ginger-derived extracellular vesicles may serve as an acid-stable, inexpensive, and supply-chain ready clinical solution to deliver 6-shogaol to macrophages, triggering CASA autophagy to degrade EBOV VP40 and halt viral egress.\"\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThis hypothesis proposes a therapeutic intervention for Ebola virus (EBOV) utilizing Ginger-derived nanovesicles (exosomes/exosome-like nanoparticles) as a delivery vehicle for 6-shogaol to activate Chaperone-Assisted Selective Autophagy (CASA) in macrophages, thereby targeting the EBOV VP40 matrix protein for degradation to inhibit viral assembly and egress. While literature confirms the role of BAG3/HSP70-mediated CASA in degrading EBOV VP40 and the utility of ginger/natural extracts (e.g., Bangle extract) in modulating autophagy, the specific delivery of 6-shogaol via ginger-derived exosomes to induce anti-VP40 autophagic degradation is not directly stated in the provided context and remains an extrapolative synthesis of disparate research domains.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe filovirus VP40 matrix protein is the primary driver of virion assembly and egress. Host factors BAG3 and HSP70 recognize VP40 as a client and inhibit the egress of VP40 virus-like particles (VLPs) by promoting degradation of VP40 via Chaperone-assisted selective autophagy (CASA). The mechanistic target of rapamycin complex 1 (mTORC1) serves as a gateway regulator of autophagy, and notably, pharmacological suppression of MTORC1 signaling by rapamycin activates autophagy and blocks filovirus egress. BAG3 is a stress induced protein that regulates cellular protein homeostasis and cell survival through chaperone-mediated autophagy (CMA). Similar to our previously published findings for the VP40 proteins of Ebola and Marburg viruses, our results using VLP budding assays, BAG3 knockout cells, and confocal microscopy indicate that BAG3 is a WW-domain interactor that negatively regulates egress of LFV Z VLPs, rather than promoting VLP release. \n\nWhile plant-based extracts such as Bangle (Zingiber purpureum Rosc.) have been shown to ameliorate inflammation and upregulate autophagy in colitis models, evidence specifically linking 6-shogaol (a ginger constituent) delivered via ginger exosomes to EBOV VP40 degradation is currently absent from the provided literature. The proposal relies on the known ability of exosomal delivery systems to navigate biological barriers and the established role of CASA in restricting filovirus egress.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* The host protein BAG3 acts as a negative regulator of filovirus egress by sequestering VP40.\n* CASA (Chaperone-assisted selective autophagy) provides a dedicated host defense mechanism against viral matrix protein egress.\n* The mTORC1/CASA axis represents a critical nexus for future antiviral drug intervention.\n* Reticulophagy receptors like FAM134B/RETREG1 independently target viral glycoproteins (GP) for degradation in the ER.\n* EBOV hijacks multiple proteostasis networks, including the calnexin cycle, ERAD, and reticulophagy, to balance viral fitness.\n* MicroRNA expression changes in EBOV-infected cells potentially modulate autophagic pathways.\n* LC3B-II is not only a marker but a functional participant in the internalization of EBOV particles.\n* Exosomal delivery technologies are increasingly utilized for PROTACs and other targeted antiviral modalities.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

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: 40223186\nTitle: Dual roles of CXCR4 (C-X-C motif chemokine receptor 4) in promoting entry of ebolavirus and targeting excessive glycoprotein for reticulophagic degradation to facilitate viral fitness.\nAbstract: Ebola virus disease (EVD) caused by Zaire Ebolavirus (EBOV) infection is a major threat to public health in Africa and even worldwide, due to its extremely high mortality rate. However, there are still no effective antiviral therapies that can completely cure EVD. A comprehensive understanding of virus-host interactions would be beneficial for developing new antiviral agents. Here, we showed that CXCR4-induced macroautophagy/autophagy and was internalized to endosomes by interacting with glycoprotein (GP) on viral particles during EBOV infection; this promoted the EBOV attachment and entry, which was reduced by CXCR4 antagonist and neutralizing antibody. We also found that CXCR4 increased EBOV replication by downregulating cytotoxic GP to promote viral fitness instead of influencing the assembly of viral factory. Mechanistically, excessive EBOV GP could hijack CXCR4 sorting and transporting pathways by their interactions with HGS, one of the key components of the ESCRT machinery; subsequently GP could be carried back to the endoplasmic reticulum by CXCR4, where the E3 ubiquitin ligase RNF185 was recruited to polyubiquitinate GP in a K27- and K63-linked manner. Finally, polyubiquitinated GP was degraded in lysosomes via reticulophagy by interacting with RETREG1 (reticulophagy regulator 1), in an ATG3- and ATG5-dependent manner. Our findings revealed dual roles of CXCR4 in regulation of EBOV life cycle, either acting as an entry factor by interacting with GP on viral particles to facilitate viral entry or targeting excessive GP for reticulophagic degradation, providing new evidence that EBOV hijacked the host vesicular transportation system through efficient virus-host interactions to facilitate viral fitness.Abbreviations: Baf A1: bafilomycin A1; BDBV: Bundibugyo Ebolavirus; CHX: cycloheximide; CXCR4: C-X-C motif chemokine receptor 4; CLEC4M/DC-SIGNR: C type lectin domain family 4 member M; EBOV: Zaire Ebolavirus; EEA1: early endosome antigen 1; ER: endoplasmic reticulum; ERAD: ER-associated degradation; ESCRT: endosomal sorting complex required for transport; EVD: Ebolavirus disease; HAVCR1/TIM-1: hepatitis A virus cellular receptor 1; GP: glycoprotein; HGS: hepatocyte growth factor-regulated tyrosine kinase substrate; HIV: human immunodeficiency virus; IFL: internal fusion loop; ITCH/AIP4: itchy E3 ubiquitin protein ligase; LAMP: lysosomal associated membrane protein; LC-MS/MS: liquid chromatography mass spectrometry; PDIs: protein disulfide isomerases; RBD: receptor binding domain; RESTV: Reston Ebolavirus; RETREG1: reticulophagy regulator 1; RNF185: ring finger protein 185; SQSTM1/p62: sequestosome 1; SUDV: Sudan Ebolavirus; TAFV: Ta\u00ef Forest Ebolavirus; TRIM21: tripartite motif containing 21; trVLPs: transcription- and replication-competent virus-like particles; Ub: ubiquitin.\n\nID: 40177841\nTitle: Bangle (Zingiber purpureum Rosc.) Extract Ameliorates Colonic Inflammation and Upregulates Autophagy via the Modulation of the AMPK/mTOR/NF\u03baB Pathway in a Mouse Colitis Model.\nAbstract: Bangle, a perennial herb belonging to the ginger family with antiinflammatory properties, has been under-researched in ulcerative colitis. This study aimed to investigate the effects of Bangle extract (BaE) on inflammation and autophagy in the colons of mice with dextran sulfate sodium (DSS)-induced colitis. Male C57BL/6J mice were assigned to four groups: control, DSS\u00a0+\u00a00% BaE, DSS\u00a0+\u00a01% BaE, and DSS\u00a0+\u00a03% BaE. The BaE groups were fed BaE diets for 3 weeks, followed by an additional week of BaE diets and 3% DSS in the water. The control group received a standard chow diet and water for 4 weeks. Plasma leucine-rich \u03b12-glycoprotein (LRG) levels, macrophage count, and the levels of nuclear factor kappa B (NF\u03baB) p65, tumor necrosis factor-\u03b1 (TNF-\u03b1), adenosine monophosphate-activated protein kinase (AMPK), peroxisome proliferator-activated receptor \u03b3 coactivator-1\u03b1 (PGC-1\u03b1), mechanistic target of rapamycin (mTOR), and autophagy markers were analyzed. In the DSS\u00a0+\u00a00% BaE group, LRG levels, macrophage count, NF\u03baB p65 protein, and TNF-\u03b1 mRNA levels were significantly higher compared to the control group. However, in the DSS\u00a0+\u00a03% BaE group, these levels were significantly reduced. Additionally, PGC-1\u03b1 and phosphorylated AMPK levels were increased, while phosphorylated mTOR levels decreased, and autophagy marker microtubule-associated protein 1 light chain 3B (LC3B)-II levels were increased in the DSS\u00a0+\u00a03% BaE group. BaE may ameliorate colonic inflammation and upregulate autophagy via the modulation of the AMPK/mTOR/NF\u03baB pathway in DSS-induced colitis.\n\nID: 39128851\nTitle: AP3B1 facilitates PDIA3/ERP57 function to regulate rabies virus glycoprotein selective degradation and viral entry.\nAbstract: Rabies virus causes an estimated 59,000 annual fatalities worldwide and promising therapeutic treatments are necessary to develop. In this study, affinity tag-purification mass spectrometry was employed to delineate RABV glycoprotein and host protein interactions, and PDIA3/ERP57 was identified as a potential inhibitor of RABV infection. PDIA3 restricted RABV infection with follow mechanisms: PDIA3 mediated the degradation of RABV G protein by targeting lysine 332 via the selective macroautophagy/autophagy pathway; The PDIA3 interactor, AP3B1 (adaptor related protein complex 3 subunit beta 1) was indispensable in PDIA3-triggered selective degradation of the G protein; Furthermore, PDIA3 competitively bound with NCAM1/NCAM (neural cell adhesion molecule 1) to block RABV G, hindering viral entry into host cells. PDIA3 190-199 aa residues bound to the RABV G protein were necessary and sufficient to defend against RABV. These results demonstrated the therapeutic potential of biologics that target PDIA3 or utilize PDIA3 190-199 aa peptide to treat clinical rabies.Abbreviation: aa: amino acids; ANXA2: annexin A2; AP-MS: affinity tag purification-mass spectrometry; AP3B1: adaptor related protein complex 3 subunit beta 1; ATP6V1A: ATPase H+ transporting V1 subunit A; ATP6V1H: ATPase H+ transporting V1 subunit H; BafA1: bafilomycin A1; CHX: cycloheximide; co-IP: co-immunoprecipitation; DDX17: DEAD-box helicase 17; DmERp60: drosophila melanogaster endoplasmic reticulum p60; EBOV: Zaire ebolavirus virus; EV: empty vector; GANAB: glucosidase II alpha subunit; G protein: glycoprotein; GRM2/mGluR2: glutamate metabotropic receptor 2; HsPDIA3: homo sapiens protein disulfide isomerase family A member 3; IAV: influenza virus; ILF2: interleukin enhancer binding factor 2; KO: knockout; MAGT1: magnesium transporter 1; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; MmPDIA3: mus musculus protein disulfide isomerase associated 3; NCAM1/NCAM: neural cell adhesion molecule 1; NGFR/p75NTR: nerve growth factor receptor; NGLY1: N-glycanase 1; OTUD4: OTU deubiquitinase 4; PDI: protein disulfide isomerase; PPIs: protein-protein interactions; RABV: rabies virus; RUVBL2: RuvB like AAA ATPase 2; SCAMP3: secretory carrier membrane protein 3; ScPdi1: Saccharomyces cerevisiae s288c protein disulfide isomerase 1; SLC25A6: solute carrier family 25 member 6; SQSTM1/p62: sequestosome 1; VSV: vesicular stomatitis virus.\n\nID: 38796097\nTitle: Exosome-mediated PROTAC delivery for treatment of RNA viral infections and zoonosis.\nAbstract: The increase in diseases caused by RNA viruses, such as influenza, severe acute respiratory syndrome-coronavirus (SARS-CoV), Middle East respiratory syndrome (MERS), and Ebola, presents a growing global health challenge as well as the threat of zoonosis. Traditional antiviral treatments are often undermined by fast-mutating viruses, drug resistance, and newly emerging pathogens. Here, we explore proteolysis-targeting chimeras (PROTACs), a novel protein degradation machinery that has the potential to reshape the way in which RNA viral infections can be managed. PROTACs excel at specifically degrading pathogenic proteins, offering a targeted and efficient antiviral strategy. We also investigate the potential of exosome-based diagnostic technologies, which harness cell-derived nanovesicles for non-invasive sampling and early viral infection detection. Addressing the challenge of PROTAC delivery, we introduce a groundbreaking strategy utilizing exosomes to deliver PROTACs with improved precision and as a targeted delivery vehicle. Integrating these innovative strategies provides a novel approach to combat RNA zoonotic viral diseases, paving the way for a new era in antiviral therapy.\n\nID: 37578574\nTitle: Coding Therapeutic Nucleic Acids from Recombinant Proteins to Next-Generation Vaccines: Current Uses, Limitations, and Future Horizons.\nAbstract: This study aims to highlight the potential use of cTNAs in therapeutic applications. The COVID-19 pandemic has led to significant use of coding therapeutic nucleic acids (cTNAs) in terms of DNA and mRNA in the development of vaccines. The use of cTNAs resulted in a paradigm shift in the therapeutic field. However, the injection of DNA or mRNA into the human body transforms cells into biological factories to produce the necessary proteins. Despite the success of cTNAs in the production of corona vaccines, they have several limitations such as instability, inability to cross biomembranes, immunogenicity, and the possibility of integration into the human genome. The chemical modification and utilization of smart drug delivery cargoes resolve cTNAs therapeutic problems. The success of cTNAs in corona vaccine production provides perspective for the eradication of influenza viruses, Zika virus, HIV, respiratory syncytial virus, Ebola virus, malaria, and future pandemics by quick vaccine design. Moreover, the progress cTNAs technology is promising for the development of therapy for genetic disease, cancer therapy, and currently incurable diseases.\n\nID: 37385212\nTitle: Biomaterial-based delivery platforms for transdermal immunotherapy.\nAbstract: Nowadays, immunotherapy is one of the most essential treatments for various diseases and a broad spectrum of disorders are assumed to be treated by altering the function of the immune system. For this reason, immunotherapy has attracted a great deal of attention and numerous studies on different approaches for immunotherapies have been investigated, using multiple biomaterials and carriers, from nanoparticles (NPs) to microneedles (MNs). In this review, the immunotherapy strategies, biomaterials, devices, and diseases supposed to be treated by immunotherapeutic strategies are reviewed. Several transdermal therapeutic methods, including semisolids, skin patches, chemical, and physical skin penetration enhancers, are discussed. MNs are the most frequent devices implemented in transdermal immunotherapy of cancers (e.g., melanoma, squamous cell carcinoma, cervical, and breast cancer), infectious (e.g., COVID-19), allergic and autoimmune disorders (e.g., Duchenne's muscular dystrophy and Pollinosis). The biomaterials used in transdermal immunotherapy vary in shape, size, and sensitivity to external stimuli (e.g., magnetic field, photo, redox, pH, thermal, and even multi-stimuli-responsive) were reported. Correspondingly, vesicle-based NPs, including niosomes, transferosomes, ethosomes, microemulsions, transfersomes, and exosomes, are also discussed. In addition, transdermal immunotherapy using vaccines has been reviewed for Ebola, Neisseria gonorrhoeae, Hepatitis B virus, Influenza virus, respiratory syncytial virus, Hand-foot-and-mouth disease, and Tetanus.\n\nID: 36763514\nTitle: Chaperoning the driver of filovirus egress to a dead end.\nAbstract: Ebola virus (EBOV) and Marburg virus (MARV) are zoonotic, virulent pathogens that cause sporadic and global outbreaks of severe hemorrhagic fever. Reemergence of these filoviruses remains a global public health threat, highlighting the need for novel countermeasures to control and treat future disease outbreaks. The EBOV VP40 matrix protein drives virion assembly and egress. We recently reported that BAG3 and HSPA/HSP70, two central components of chaperone-assisted selective autophagy (CASA), target VP40 for autophagic sequestration and degradation, thereby inhibiting virus egress and spread. In addition, we found that expression of the EBOV glycoprotein (GP) activates MTORC1, the gateway regulator of autophagy. Notably, pharmacological suppression of MTORC1 signaling by rapamycin activates autophagy and blocks filovirus egress. These findings highlight the MTORC1-CASA axis as a regulator of filovirus egress and suggest new opportunities for antiviral development and intervention.\n\nID: 36598950\nTitle: Chaperone-assisted selective autophagy targets filovirus VP40 as a client and restricts egress of virus particles.\nAbstract: The filovirus VP40 protein directs virion egress, which is regulated either positively or negatively by select VP40-host interactions. We demonstrate that host BAG3 and HSP70 recognize VP40 as a client and inhibit the egress of VP40 virus-like particles (VLPs) by promoting degradation of VP40 via Chaperone-assisted selective autophagy (CASA). Pharmacological inhibition of either the early stage formation of the VP40/BAG3/HSP70 tripartite complex, or late stage formation of autolysosomes, rescued VP40 VLP egress back to WT levels. The mechanistic target of rapamycin complex 1 (mTORC1) is a master regulator of autophagy, and we found that surface expression of EBOV GP on either VLPs or an infectious VSV recombinant virus, activated mTORC1. Notably, pharmacological suppression of mTORC1 signaling by rapamycin activated CASA in a BAG3-dependent manner to restrict the egress of both VLPs and infectious EBOV in Huh7 cells. In sum, our findings highlight the involvement of the mTORC1/CASA axis in regulating filovirus egress.\n\nID: 36224200\nTitle: RNF185 regulates proteostasis in Ebolavirus infection by crosstalk between the calnexin cycle, ERAD, and reticulophagy.\nAbstract: Virus infection affects cellular proteostasis and provides an opportunity to study this cellular process under perturbation. The proteostasis network in the endoplasmic reticulum (ER) is composed of the calnexin cycle, and the two protein degradation pathways ER-associated protein degradation (ERAD) and ER-to-lysosome-associated degradation (ERLAD/ER-phagy/reticulophagy). Here we show that calnexin and calreticulin trigger Zaire Ebolavirus (EBOV) glycoprotein GP1,2 misfolding. Misfolded EBOV-GP1,2 is targeted by ERAD machinery, but this results in lysosomal instead of proteasomal degradation. Moreover, the ER Ub ligase RNF185, usually associated with ERAD, polyubiquitinates EBOV-GP1,2 on lysine 673 via ubiquitin K27-linkage. Polyubiquinated GP1,2 is subsequently recruited into autophagosomes by the soluble autophagy receptor sequestosome 1 (SQSTM1/p62), in an ATG3- and ATG5-dependent manner. We conclude that EBOV hijacks all three proteostasis mechanisms in the ER to downregulate GP1,2 via polyubiquitination and show that this increases viral fitness. This study identifies linkages among proteostasis network components previously thought to function independently.\n\nID: 35367363\nTitle: Multifunctional role of exosomes in viral diseases: From transmission to diagnosis and therapy.\nAbstract: Efforts to discover antiviral drugs and diagnostic platforms have intensified to an unprecedented level since the outbreak of COVID-19. Nano-sized endosomal vesicles called exosomes have gained considerable attention from researchers due to their role in intracellular communication to regulate the biological activity of target cells through cargo proteins, nucleic acids, and lipids. According to recent studies, exosomes play a vital role in viral diseases including covid-19, with their interaction with the host immune system opening the door to effective antiviral treatments. Utilizing the intrinsic nature of exosomes, it is imperative to elucidate how exosomes exert their effect on the immune system or boost viral infectivity. Exosome biogenesis machinery is hijacked by viruses to initiate replication, spread infection, and evade the immune response. Exosomes, however, also participate in protective mechanisms by triggering the innate immune system. Besides that, exosomes released from the cells can carry a robust amount of information about the diseased state, serving as a potential biomarker for detecting viral diseases. This review describes how exosomes increase virus infectivity, act as immunomodulators, and function as a potential drug delivery carrier and diagnostic biomarker for diseases caused by HIV, Hepatitis, Ebola, and Epstein-Barr viruses. Furthermore, the review analyzes various applications of exosomes within the context of COVID-19, including its management.\n\nID: 35130104\nTitle: Protein disulfide isomerases (PDIs) negatively regulate ebolavirus structural glycoprotein expression in the endoplasmic reticulum (ER) via the autophagy-lysosomal pathway.\nAbstract: Zaire ebolavirus (EBOV) causes a severe hemorrhagic fever in humans and non-human primates with high morbidity and mortality. EBOV infection is dependent on its structural glycoprotein (GP), but high levels of GP expression also trigger cell rounding, detachment, and downregulation of many surface molecules that is thought to contribute to its high pathogenicity. Thus, EBOV has evolved an RNA editing mechanism to reduce its GP expression and increase its fitness. We now report that the GP expression is also suppressed at the protein level in cells by protein disulfide isomerases (PDIs). Although PDIs promote oxidative protein folding by catalyzing correct disulfide formation in the endoplasmic reticulum (ER), PDIA3/ERp57 adversely triggered the GP misfolding by targeting GP cysteine residues and activated the unfolded protein response (UPR). Abnormally folded GP was targeted by ER-associated protein degradation (ERAD) machinery and, unexpectedly, was degraded via the macroautophagy/autophagy-lysosomal pathway, but not the proteasomal pathway. PDIA3 also decreased the GP expression from other ebolavirus species but increased the GP expression from Marburg virus (MARV), which is consistent with the observation that MARV-GP does not cause cell rounding and detachment, and MARV does not regulate its GP expression via RNA editing during infection. Furthermore, five other PDIs also had a similar inhibitory activity to EBOV-GP. Thus, PDIs negatively regulate ebolavirus glycoprotein expression, which balances the viral life cycle by maximizing their infection but minimizing their cellular effect. We suggest that ebolaviruses hijack the host protein folding and ERAD machinery to increase their fitness via reticulophagy during infection.Abbreviations: 3-MA: 3-methyladenine; 4-PBA: 4-phenylbutyrate; ACTB: \u03b2-actin; ATF: activating transcription factor; ATG: autophagy-related; BafA1: bafilomycin A1; BDBV: Bundibugyo ebolavirus; CALR: calreticulin; CANX: calnexin; CHX: cycloheximide; CMA: chaperone-mediated autophagy; ConA: concanamycin A; CRISPR: clusters of regularly interspaced short palindromic repeats; Cas9: CRISPR-associated protein 9; dsRNA: double-stranded RNA; EBOV: Zaire ebolavirus; EDEM: ER degradation enhancing alpha-mannosidase like protein; EIF2AK3/PERK: eukaryotic translation initiation factor 2 alpha kinase 3; Env: envelope glycoprotein; ER: endoplasmic reticulum; ERAD: ER-associated protein degradation; ERN1/IRE1: endoplasmic reticulum to nucleus signaling 1; GP: glycoprotein; HA: hemagglutinin; HDAC6: histone deacetylase 6; HMM: high-molecular-mass; HIV-1: human immunodeficiency virus type 1; HSPA5/BiP: heat shock protein family A (Hsp70) member 5; IAV: influenza A virus; IP: immunoprecipitation; KIF: kifenesine; Lac: lactacystin; LAMP: lysosomal associated membrane protein; MAN1B1/ERManI: mannosidase alpha class 1B member 1; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; MARV: Marburg virus; MLD: mucin-like domain; NHK/SERPINA1: alpha1-antitrypsin variant null (Hong Kong); NTZ: nitazoxanide; PDI: protein disulfide isomerase; RAVV: Ravn virus; RESTV: Reston ebolavirus; SARS-CoV: severe acute respiratory syndrome coronavirus; SBOV: Sudan ebolavirus; sGP: soluble GP; SQSTM1/p62: sequestosome 1; ssGP: small soluble GP; TAFV: Ta\u00ef Forest ebolavirus; TIZ: tizoxanide; TGN: thapsigargin; TLD: TXN (thioredoxin)-like domain; Ub: ubiquitin; UPR: unfolded protein response; VLP: virus-like particle; VSV: vesicular stomatitis virus; WB: Western blotting; WT: wild-type; XBP1: X-box binding protein 1.\n\nID: 32521191\nTitle: Open questions for harnessing autophagy-modulating drugs in the SARS-CoV-2 war: hope or hype?\nAbstract: At a time when the world faces an emotional breakdown, crushing our dreams, if not, taking our lives, we realize that together we must fight the war against the COVID-19 outbreak even if almost the majority of the scientific community finds itself confined at home. Every day, we, scientists, listen to the latest news with its promises and announcements. Across the world, a surge of clinical trials trying to cure or slow down the coronavirus pandemic has been launched to bring hope instead of fear and despair. One first proposed clinical trial has drawn worldwide hype to the benefit of chloroquine (CQ), in the treatment of patients infected by the recently emerged deadly coronavirus (SARS-CoV-2). We should consider this information in light of the long-standing anti-inflammatory and anti-viral properties of CQ-related drugs. Yet, none of the articles promoting the use of CQ in the current pandemic evoked a possible molecular or cellular mechanism of action that could account for any efficacy. Here, given the interaction of viruses with macroautophagy (hereafter referred to as autophagy), a CQ-sensitive anti-viral safeguard pathway, we would like to discuss the pros, but also the cons concerning the current therapeutic options targeting this process.\n\nID: 31648236\nTitle: Ebola virus-mediated T-lymphocyte depletion is the result of an abortive infection.\nAbstract: Ebola virus (EBOV) infections are characterized by a pronounced lymphopenia that is highly correlative with fatalities. However, the mechanisms leading to T-cell depletion remain largely unknown. Here, we demonstrate that both viral mRNAs and antigens are detectable in CD4+ T cells despite the absence of productive infection. A protein phosphatase 1 inhibitor, 1E7-03, and siRNA-mediated suppression of viral antigens were used to demonstrate de novo synthesis of viral RNAs and antigens in CD4+ T cells, respectively. Cell-to-cell fusion of permissive Huh7 cells with non-permissive Jurkat T cells impaired productive EBOV infection suggesting the presence of a cellular restriction factor. We determined that viral transcription is partially impaired in the fusion T cells. Lastly, we demonstrate that exposure of T cells to EBOV resulted in autophagy through activation of ER-stress related pathways. These data indicate that exposure of T cells to EBOV results in an abortive infection, which likely contributes to the lymphopenia observed during EBOV infections.\n\nID: 31570108\nTitle: Expression of microRNA in human retinal pigment epithelial cells following infection with Zaire ebolavirus.\nAbstract: Survivors of Ebola virus disease (EVD) are at risk of developing blinding intraocular inflammation-or uveitis-which is associated with retinal pigment epithelial (RPE) scarring and persistence of live Zaire ebolavirus (EBOV) within the eye. As part of a large research project aimed at defining the human RPE cell response to being infected with EBOV, this work focused on the microRNAs (miRNAs) associated with the infection. Using RNA-sequencing, we detected 13 highly induced and 2 highly repressed human miRNAs in human ARPE-19 RPE cells infected with EBOV, including hsa-miR-1307-5p, hsa-miR-29b-3p and hsa-miR-33a-5p (up-regulated), and hsa-miR-3074-3p and hsa-miR-27b-5p (down-regulated). EBOV-miR-1-5p was also found in infected RPE cells. Through computational identification of putative miRNA targets, we predicted a broad range of regulatory activities, including effects on innate and adaptive immune responses, cellular metabolism, cell cycle progression, apoptosis and autophagy. The most highly-connected molecule in the miR-target network was leucine-rich repeat kinase 2, which is involved in neuroinflammation and lysosomal processing. Our findings should stimulate new studies on the impact of miRNA changes in EBOV-infected RPE cells to further understanding of intraocular viral persistence and the pathogenesis of uveitis in EVD survivors.\n\nID: 30808769\nTitle: Plasma lipidome reveals critical illness and recovery from human Ebola virus disease.\nAbstract: Ebola virus disease (EVD) often leads to severe and fatal outcomes in humans with early supportive care increasing the chances of survival. Profiling the human plasma lipidome provides insight into critical illness as well as diseased states, as lipids have essential roles as membrane structural components, signaling molecules, and energy sources. Here we show that the plasma lipidomes of EVD survivors and fatalities from Sierra Leone, infected during the 2014-2016 Ebola virus outbreak, were profoundly altered. Focusing on how lipids are associated in human plasma, while factoring in the state of critical illness, we found that lipidome changes were related to EVD outcome and could identify states of disease and recovery. Specific changes in the lipidome suggested contributions from extracellular vesicles, viremia, liver dysfunction, apoptosis, autophagy, and general critical illness, and we identified possible targets for therapies enhancing EVD survival.\n\nID: 30011814\nTitle: Host Protein BAG3 is a Negative Regulator of Lassa VLP Egress.\nAbstract: Lassa fever virus (LFV) belongs to the Arenaviridae family and can cause acute hemorrhagic fever in humans. The LFV Z protein plays a central role in virion assembly and egress, such that independent expression of LFV Z leads to the production of virus-like particles (VLPs) that mimic egress of infectious virus. LFV Z contains both PTAP and PPPY L-domain motifs that are known to recruit host proteins that are important for mediating efficient virus egress and spread. The viral PPPY motif is known to interact with specific host WW-domain bearing proteins. Here we identified host WW-domain bearing protein BCL2 Associated Athanogene 3 (BAG3) as a LFV Z PPPY interactor using our proline-rich reading array of WW-domain containing mammalian proteins. BAG3 is a stress-induced molecular co-chaperone that functions to regulate cellular protein homeostasis and cell survival via Chaperone-Assisted Selective Autophagy (CASA). Similar to our previously published findings for the VP40 proteins of Ebola and Marburg viruses, our results using VLP budding assays, BAG3 knockout cells, and confocal microscopy indicate that BAG3 is a WW-domain interactor that negatively regulates egress of LFV Z VLPs, rather than promoting VLP release. Our results suggest that CASA and specifically BAG3 may represent a novel host defense mechanism, whereby BAG3 may dampen egress of several hemorrhagic fever viruses by interacting and interfering with the budding function of viral PPxY-containing matrix proteins.\n\nID: 29947774\nTitle: Autophagy-Associated Proteins Control Ebola Virus Internalization Into Host Cells.\nAbstract: Ebola virus (EBOV) enters host cells by macropinocytosis, a poorly understood process. Recent studies have suggested that cell factors involved in autophagy, an evolutionally conserved pathway leading to the lysosomal degradation of protein aggregates and organelles during cellular stress, also have roles in macropinocytosis. Here, we demonstrate that autophagy-associated proteins are required for trafficking of EBOV into the cell body. Depleting cells of beclin 1, autophagy-related protein 7, or microtubule-associated protein 1A/B light chain 3B (LC3B) abolished EBOV uptake, owing to a block in vesicle formation at the cell surface. Both LC3B-I and LC3B-II interacted with macropinocytic structures. Our work indicates that, although various forms of LC3B possess an inherent ability to associate with forming macropinosomes, LC3B-II is critical for internalization of macropinocytic vesicles and, therefore, EBOV from the cell surface.\n\nID: 28723972\nTitle: Correction: Chaperone-Mediated Autophagy Protein BAG3 Negatively Regulates Ebola and Marburg VP40-Mediated Egress.\nAbstract: [This corrects the article DOI: 10.1371/journal.ppat.1006132.].\n\nID: 28076420\nTitle: Chaperone-Mediated Autophagy Protein BAG3 Negatively Regulates Ebola and Marburg VP40-Mediated Egress.\nAbstract: Ebola (EBOV) and Marburg (MARV) viruses are members of the Filoviridae family which cause outbreaks of hemorrhagic fever. The filovirus VP40 matrix protein is essential for virus assembly and budding, and its PPxY L-domain motif interacts with WW-domains of specific host proteins, such as Nedd4 and ITCH, to facilitate the late stage of virus-cell separation. To identify additional WW-domain-bearing host proteins that interact with VP40, we used an EBOV PPxY-containing peptide to screen an array of 115 mammalian WW-domain-bearing proteins. Using this unbiased approach, we identified BCL2 Associated Athanogene 3 (BAG3), a member of the BAG family of molecular chaperone proteins, as a specific VP40 PPxY interactor. Here, we demonstrate that the WW-domain of BAG3 interacts with the PPxY motif of both EBOV and MARV VP40 and, unexpectedly, inhibits budding of both eVP40 and mVP40 virus-like particles (VLPs), as well as infectious VSV-EBOV recombinants. BAG3 is a stress induced protein that regulates cellular protein homeostasis and cell survival through chaperone-mediated autophagy (CMA). Interestingly, our results show that BAG3 alters the intracellular localization of VP40 by sequestering VP40 away from the plasma membrane. As BAG3 is the first WW-domain interactor identified that negatively regulates budding of VP40 VLPs and infectious virus, we propose that the chaperone-mediated autophagy function of BAG3 represents a specific host defense strategy to counteract the function of VP40 in promoting efficient egress and spread of virus particles.\n\nID: 27511895\nTitle: FAM134B, the Selective Autophagy Receptor for Endoplasmic Reticulum Turnover, Inhibits Replication of Ebola Virus Strains Makona and Mayinga.\nAbstract: Selective autophagy of the endoplasmic reticulum (termed ER-phagy) is controlled by members of the FAM134 reticulon protein family. Here we used mouse embryonic fibroblasts from mice deficient in FAM134B to examine the role of the ER in replication of historic (Mayinga) or contemporary (Makona GCO7) strains of Ebola virus (EBOV). Loss of FAM134B resulted in 1-2 log10 higher production of infectious EBOV, which was associated with increased production of viral proteins GP and VP40 and greater accumulation of nucleocaspid lattices. In addition, only 10% of wild-type cells contained detectable nucleoprotein, whereas knockout of FAM134B resulted in 80% of cells positive for nucleoprotein. Together, these data suggest that FAM134B-dependent ER-phagy is an important limiting event in EBOV replication in mouse cells and may have implications for further development of antiviral therapeutics and murine models of infection.\n\nID: 27439673\nTitle: Alternative autophagy, brefeldin A and viral trafficking pathways.\nAbstract: Two topics that have attracted recent attention in the field of autophagy concern the source of the membrane that is used to form the autophagosome during macroautophagy and the role of noncanonical autophagic pathways. The 2 topics may converge when considering the intersection of autophagy with viral infection. We suggest that noncanonical autophagy, which is sensitive to treatment with brefeldin A, may converge with the infectious cycles of certain DNA and RNA viruses that utilize membrane from the ER and cis-Golgi.\n\nID: 27031961\nTitle: Longitudinal characterization of dysfunctional T cell-activation during human acute Ebola infection.\nAbstract: Data on immune responses during human Ebola virus disease (EVD) are scanty, due to limitations imposed by biosafety requirements and logistics. A sustained activation of T-cells was recently described but functional studies during the acute phase of human EVD are still missing. Aim of this work was to evaluate the kinetics and functionality of T-cell subsets, as well as the expression of activation, autophagy, apoptosis and exhaustion markers during the acute phase of EVD until recovery. Two EVD patients admitted to the Italian National Institute for Infectious Diseases, Lazzaro Spallanzani, were sampled sequentially from soon after symptom onset until recovery and analyzed by flow cytometry and ELISpot assay. An early and sustained decrease of CD4 T-cells was seen in both patients, with an inversion of the CD4/CD8 ratio that was reverted during the recovery period. In parallel with the CD4 T-cell depletion, a massive T-cell activation occurred and was associated with autophagic/apoptotic phenotype, enhanced expression of the exhaustion marker PD-1 and impaired IFN-gamma production. The immunological impairment was accompanied by EBV reactivation. The association of an early and sustained dysfunctional T-cell activation in parallel to an overall CD4 T-cell decline may represent a previously unknown critical point of Ebola virus (EBOV)-induced immune subversion. The recent observation of late occurrence of EBOV-associated neurological disease highlights the importance to monitor the immuno-competence recovery at discharge as a tool to evaluate the risk of late sequelae associated with resumption of EBOV replication. Further studies are required to define the molecular mechanisms of EVD-driven activation/exhaustion and depletion of T-cells.\n\nID: 42571123\nTitle: Cardiovascular Diseases and Cancer: Convergent Proteostasis Networks at the Crossroads of Mechanisms and Therapeutic Opportunities.\nAbstract: Cancer and cardiovascular diseases, the primary causes of mortality globally, are increasingly understood as biologically interconnected rather than distinct pathologies. Recent evidence indicates that protein homeostasis (proteostasis) functions as a crucial molecular link connecting tumor progression, therapeutic resistance, cardiac remodeling, and treatment-related cardiotoxicity. Proteostasis, which encompasses the cellular processes of protein synthesis, folding, quality control, and degradation, dictates tissue adaptation to chronic stress. Notably, the adaptive mechanisms that allow tumor cells to endure proteotoxic stress and resist therapy are often vital for maintaining cardiac structure and function. Thus, tumor control and cardiovascular injury may be divergent outcomes of a common stress-response framework. In this review, we propose proteostasis as a comprehensive framework for understanding the cancer-cardiovascular interface. We analyze how the ubiquitin-proteasome system, autophagy-lysosome pathway, endoplasmic reticulum stress-induced unfolded protein response signaling, and molecular chaperone networks are differentially reconfigured in cancer and cardiac tissues, influencing tumor survival, therapeutic susceptibility, and cardiovascular dysfunction. Additionally, we explore the translational implications of proteostasis dysregulation, including mechanisms of anticancer therapy-induced cardiotoxicity, emerging biomarkers, cardioprotective strategies, and opportunities for precision cardio-oncology. By conceptualizing efficacy and toxicity as interconnected outcomes of shared proteostasis biology, this review establishes a foundation for developing therapies that optimize cancer control while safeguarding cardiovascular health.\n\nID: 42571027\nTitle: Fisetin alleviates zinc overload-induced intestinal injury by inhibiting ferroptosis and remodeling gut microbiota in weaned piglets.\nAbstract: High doses of zinc oxide (ZnO) effectively prevent post-weaning diarrhea and promote growth in weaned piglets, but raise concerns over intestinal injury, metabolic disorders, and risks of fostering bacterial resistance. This study aimed to identify non-chelating polyphenols capable of mitigating zinc toxicity and to elucidate their protective mechanisms, with emphasis on ferroptosis inhibition. Network toxicology predicted ferroptosis as a central mechanism in zinc-induced intestinal injury, which was confirmed in intestinal epithelial cells where zinc overload specifically induced ferroptosis without activating apoptosis, necroptosis, or autophagy. From multiple polyphenols, fisetin (FIS) was identified as a non-chelating candidate that alleviated zinc-induced cytotoxicity, preserved tight junction proteins, and activated the Nrf2-GPX4 axis to inhibit ferroptosis in vitro. In zinc-overloaded weaned piglets, FIS supplementation maintained the growth-promoting effects of high-dose zinc while ameliorating intestinal damage. FIS also attenuated oxidative stress, alleviated inflammation, and inhibited ferroptosis in the jejunum. Furthermore, FIS remodeled the gut microbiota, enriching beneficial taxa Romboutsia (positively correlated with growth performance) and Clostridium_sensu_stricto_1 (positively correlated with the p-Nrf2/Nrf2 ratio), while suppressing the zinc-enriched Anaerovibrio (negatively correlated with GPX4 protein expression). FIS also shifted microbial metabolic pathways toward amino acid and terpenoid metabolism, potentially contributing to the observed ferroptosis defense. FIS alleviates high-dose ZnO-induced intestinal injury in weaned piglets through dual modulation, activating the Nrf2-GPX4 axis to inhibit ferroptosis and remodeling the gut microbiota to reinforce this defense. By preserving the growth benefits of zinc while mitigating its toxicity, FIS represents a promising nutritional strategy for sustainable swine production.\n\nID: 42571011\nTitle: Retraction Note: Blockage of AMPK-ULK1 pathway mediated autophagy promotes cell apoptosis to increase doxorubicin sensitivity in breast cancer (BC) cells: an in vitro study.\nAbstract: \n\nID: 42570829\nTitle: Bimetallic modified titanium carbide nanoparticles loaded with transcription factor E3 ameliorate intervertebral disc degeneration by eliminating reactive oxygen species and promoting autophagic flux.\nAbstract: Intervertebral disc (IVD) degeneration (IVDD) is a major cause of lower back pain, characterized by oxidative stress accumulation and impaired autophagic flux leading to nucleus pulposus cell (NPC) degeneration. Transcription factor E3 (TFE3) is crucial in autophagy regulation. MXene, a nanomaterial known for its antioxidant capability, exhibits satisfactory therapeutic effects in various diseases. This study investigates the role of TFE3 and evaluates the therapeutic potential of Ti3C2 MXene-based nanocomposites in IVDD. The Ti3C2@PtAu@TFE3 nanocomposite was designed, with properties of anti-oxidation and pro-autophagic flux, alleviated extracellular matrix (ECM) degradation and senescence in NPCs. In a needle puncture-induced IVDD rat model, intra-disc injection of Ti3C2@PtAu@TFE3 alleviated structural deterioration and prevented ECM destruction. This study highlights the critical role of TFE3 in IVDD pathogenesis and demonstrates the potential application of Ti3C2@PtAu@TFE3 against IVDD.\n\nID: 42570828\nTitle: Dual-site CRISPR/Cas9-mediated mutations in Toll-like receptor 4 (TLR4): complete characterization reveals divergent autophagic reprogramming of LPS-related downstream activities.\nAbstract: Lipopolysaccharide (LPS) initiates hyperinflammatory cascade via the LBP-CD14-MD2-TLR4 complex which can precipitate fatal cytokine storms and septic shock. We aim to develop molecular strategies that selectively dampen TLR4-driven inflammation without eliminating host defense. Here, we demonstrate that CRISPR-Cas9-mediated dual-site editing of the TLR4 gene, by introducing specific disruptions in both the extracellular domain (ECD) and the intracellular Toll/IL-1 receptor (TIR) domain, can generate a partially uncoupled signaling phenotype that selectively attenuates acute inflammation while preserving baseline stress-adaptive mechanisms. By combining whole-genome and amplicon-based next-generation sequencing, RNA-Seq, molecular dynamics simulations, transmission electron microscopy (TEM), GSEA, and functional reporter assays, we show that targeted mutations near the LPS-binding interface within the LRR modules of the ECD (M209I, V254I, E593D) and within the CD loop of the TIR domain (R761H) reduce ligand binding-pocket volume by ~17% (688.19\u00c53 vs. 825.41\u00c53) within TLR4 loci, leading to partial signal propagation and altered LPS trafficking to lysosomal compartments through autophagosome sequestration. Immunofluorescence profiling revealed broad attenuation of TLR-signaling networks, MyD88/TRAF6 recruitment, and downstream NF\u03baB-MAPK-PI3K-AKT-JAK-STAT-mTOR cascades alongside decreased CD14 expression, suppressed ROS generation, and diminished caspase-3 activity. While complementary NF\u03baB and LC3-HiBiT reporter assays confirmed interrupted LPS-induced inflammatory transcription and conventional autophagic flux activation, TFEB reporters revealed that edited macrophages remain highly sensitive and responsive to direct metabolic mTOR-dependent metabolic inhibition via Rapamycin. Collectively, our findings establish TLR4 as a central molecular switch and suggest that CRISPR-Cas9-mediated dual-site editing reprograms macrophages into repair-oriented, adaptive phenotype with implications for therapeutic strategies targeting inflammation, sepsis, and autophagy-driven tissue protection.\n\nID: 42570750\nTitle: Dicyclohexyl phthalate exposure impairs early embryonic development and disrupts offspring reproductive function via oxidative stress-mediated mitophagy.\nAbstract: Dicyclohexyl phthalate (DCHP) is a widely detected environmental endocrine-disrupting chemical found in various consumer products. Maternal exposure to DCHP may adversely affect offspring health. However, its effects on early embryonic development and female offspring, and the underlying mechanisms affecting offspring reproductive function remain unclear. In this study, using an in vitro mouse embryo culture system and a maternal gestational exposure model, we found that DCHP exposure induced DNA damage, disrupted spindle morphology and chromosome alignment during the first cleavage of early mouse embryos, accompanied by reduced blastocyst formation. Transcriptomic analysis of ovarian tissues from high-dose DCHP-exposed offspring revealed enrichment of pathways related to mitochondrial dysfunction and apoptosis. Functional validation showed that DCHP exposure was associated with oxidative stress and mitochondrial dysfunction, characterized by increased reactive oxygen species levels and reduced mitochondrial membrane potential, along with increased autophagy and apoptosis. Rescue assays using Mito-TEMPO and Mdivi-1 alleviated DCHP-induced mitochondrial damage and restored blastocyst developmental competence, suggesting that mitochondrial dysfunction and subsequent mitophagy activation act as key upstream events in DCHP-induced embryonic damage. Moreover, gestational exposure to the highest dose of DCHP significantly increased ovarian apoptosis and reduced oocyte maturation in female offspring. Collectively, these findings suggest that gestational high-dose DCHP exposure is linked to reduced reproductive potential and ovarian dysfunction in female offspring through oxidative stress-mediated mitophagy, providing new insights into female reproductive dysfunction associated with environmental phthalates.\n\nID: 42570748\nTitle: The effects of Metformin on myocardial ischemia and reperfusion injury in diabetic rats and its potential mechanism.\nAbstract: Diabetic cardiovascular disease remains the leading cause of mortality in patients with diabetes, underscoring the urgent need for effective therapeutic strategies to improve clinical outcomes and prevent major adverse cardiovascular events in this high-risk population. Metformin, a widely prescribed antihyperglycemic agent, not only lowers blood glucose levels but also modulates multiple intracellular signaling pathways, thereby exerting pleiotropic effects. The present study aimed to evaluate the cardioprotective effects of metformin and elucidate its underlying molecular mechanisms in myocardial ischemia-reperfusion injury. Accordingly, we established in vivo diabetic models and in vitro hyperglycemic conditions to assess the effects of metformin on myocardial tissue in diabetes. The results demonstrated that metformin treatment significantly ameliorated cardiac dysfunction and attenuated myocardial morphological abnormalities in diabetic rats subjected to ischemia-reperfusion, and concurrently improved cardiomyocyte viability under hyperglycemic conditions. Moreover, metformin enhanced autophagy, promoted mitophagic activity, and restored mitochondrial homeostasis-effects that were further validated using compound C in cultured cardiomyocytes under hyperglycemic conditions. Collectively, these findings indicate that metformin confers cardioprotection against myocardial ischemia-reperfusion injury (MIRI) through activation of AMP-activated protein kinase (AMPK) and its downstream signaling cascades, thereby regulating mitophagic processes.\n\nID: 42551544\nTitle: tRNA-derived fragment tRF-17-8SPOL52 induces resistance to bortezomib in multiple myeloma via autophagy activation.\nAbstract: Drug resistance limits the long-term survival of patients with multiple myeloma. The role of tRNA-derived fragments (tsRNAs) in bortezomib resistance in myeloma remains unknown. In this study, the most significantly upregulated tsRNA in relapsed/refractory myeloma was screened. RNA interference was used to explore the function of this tsRNA. The mechanism of the tsRNA-mediated resistance was explored by Ago-RIP-sequencing, dual-luciferase reporter assay, and transmission electron microscopy. tRF-17-8SPOL52 was identified as the most highly expressed tsRNA in relapsed/refractory myeloma. tRF-17-8SPOL52 promoted bortezomib resistance in vitro and in vivo. Ago-RIP-sequencing and dual-luciferase reporter assay showed that tRF-17-8SPOL52 negatively regulated RUBCN. Data from Ago-silenced myeloma cells suggested that the regulation of RUBCN by tRF-17-8SPOL52 was Ago-dependent. Further research showed increased autophagy induced by tRF-17-8SPOL52. In constructed RUBCN overexpressed or inhibited myeloma cells, tRF-17-8SPOL52 promoted cell autophagy by inhibiting RUBCN. Rescue experiments with chloroquine and rapamycin showed that tRF-17-8SPOL52 mediated bortezomib resistance by promoting autophagy. We concluded that tRF-17-8SPOL52 activates autophagy by inhibiting RUBCN in an Ago-dependent manner, which in turn leads to bortezomib resistance in myeloma.\n\nID: 42570312\nTitle: Drug-induced autophagic myopathies: Exploring pathophysiology with immunolabelling and proteomics.\nAbstract: Hydroxychloroquine (HCQ), chloroquine (CQ), and colchicine are widely used to treat autoimmune and inflammatory diseases but can cause toxic autophagic vacuolar myopathies. This study investigates the pathological mechanisms of HCQ/CQ- and colchicine-induced myopathies through integrated clinical, histopathological, ultrastructural, and proteomic analyses. Nine patients with clinicopathologically defined toxic myopathy (HCQ/CQ, n\u2009=\u20094; colchicine, n\u2009=\u20095) were included. Muscle biopsies were analyzed using histoenzymology, immunohistochemistry for autophagic and immune markers, electron microscopy, and proteomic profiling in selected cases. Clinically, both groups presented with proximal muscle weakness and myalgia after variable drug exposure. Histology revealed rimmed and non-rimmed vacuoles, especially in HCQ/CQ cases, and myofibrillar disorganization; the latter predominated in colchicine-treated patients. Electron microscopy confirmed myofibrillar disruption in colchicine-treated patients and autophagosomes with curvilinear bodies in HCQ/CQ cases. Immunohistochemistry showed MHC-I upregulation, heterogeneous C5b-9 deposition, and accumulation of LC3 and p62, with evidence of endoplasmic reticulum stress and transcriptional dysregulation by GRP170 overexpression and cytoplasmic MeCP2 redistribution. Proteomic analysis revealed a shared molecular signature involving immune activation, extracellular matrix remodeling, cytoskeletal stress, mitochondrial dysfunction, and dysregulation of the autophagy-lysosome pathway. Overall, HCQ/CQ- and colchicine-induced myopathies converge on common mechanisms of autophagic impairment, immune activation, and disrupted muscle homeostasis.\n\nID: 42570241\nTitle: Diurnal regulation of Acyl-CoA synthetase 3 (ACSF3) governs rhythmic mitochondrial lysine-malonylation and daily hepatic metabolism.\nAbstract: Hepatic daily rhythms are coordinated by feeding and the molecular circadian clock, ensuring metabolic homeostasis. Disrupted feeding schedules promote circadian misalignment and metabolic diseases but the underlying mechanisms remain scarce. Post-translational modifications have emerged as key regulators of circadian metabolic outputs. Here, we show that the mitochondrial enzyme Acyl-CoA synthetase family member 3 (ACSF3) oscillates in phase with different feeding schedules to drive rhythmic lysine-malonylation and coordinate daily hepatic metabolism. Hepatic Acsf3 knockdown drastically affected lysine-malonylation rhythms, decreased fasting glycemia, insulin sensitivity, and AKT phosphorylation, indicative of perturbed glucose homeostasis. Concomitantly, Acsf3 knockdown shifted lipid oxidation from mitochondria to peroxisomes, enhanced lipogenesis and triglyceride synthesis, while increasing diurnal autophagy. Multi-omics profiling uncovered specific lysine-malonylation targets in glycolysis, the tricarboxylic acid (TCA) cycle, fatty-acid oxidation and autophagy. Our findings uncover hepatic ACSF3 as a pivotal molecular nexus that integrates feeding time with dynamic protein lysine-malonylation and orchestrates the diurnal rhythm of liver metabolism.\n\nID: 42570179\nTitle: CCDC50 Alleviates Cerebral Ischemia-Reperfusion Injury via Enhancing Autophagy to Inhibit STING/IRF3-Mediated Microglial Polarization.\nAbstract: Ischemia-reperfusion injury (IRI) is a major reason for adverse prognosis in ischemic stroke, with multiple signaling pathways involved in this process. This study aims to explore the role of the novel autophagy receptor CCDC50 in cerebral IRI and its molecular mechanism. Cellular oxygen-glucose deprivation/reoxygenation model and middle cerebral artery occlusion (MCAO) animal model were adopted in this study. Quantitative real-time polymerase chain reaction, Western blot, immunofluorescence, and immunohistochemistry assays were applied to detect the expression and subcellular localization of key molecules including LL37, CCDC50, STING, IRF3, Rspondin3, and autophagy-related proteins. Co-immunoprecipitation was performed to explore protein-protein interactions. Enzyme-linked immunosorbent assay and flow cytometry were utilized to determine the levels of inflammatory cytokines and the M1/M2 polarization phenotypes of microglia. Additionally, 2,3,5-triphenyltetrazolium chloride staining was carried out to measure cerebral infarct volume. Results revealed that LL37 directly bound to CCDC50 and facilitated its ubiquitination and degradation. This process disrupted the interaction between CCDC50 and STING, thereby triggering the activation of the STING/IRF3 signaling pathway. Conversely, CCDC50 enhanced autophagy and restrained the STING/IRF3 pathway activation. It further drove microglial polarization toward the anti-inflammatory M2 phenotype, blocked pro-inflammatory M1 phenotype transition and inflammatory cytokine secretion, and ultimately alleviated neuronal damage. The above in vitro molecular mechanisms were also validated in the MCAO model. By enhancing autophagy, CCDC50 suppresses the STING/IRF3 pathway and facilitates M2 polarization of microglia, ultimately mitigating cerebral ischemia-reperfusion injury. In contrast, LL37 counteracts this protective effect by mediating CCDC50 degradation. This study identifies novel potential therapeutic targets for ischemic stroke.\n\nID: 42569414\nTitle: Eradicating Helicobacter pylori and reversing precancerous intestinal metaplasia by gastric epithelial cells-localizable oral nanomedicines.\nAbstract: The ability to treat Helicobacter pylori (H. pylori) infection and eliminate its associated gastric cancer risk is highly desirable but has proven to be extremely difficult. In this study, pilot proteomic screening of clinical gastric mucosal samples suggested a progressive decline in Sirtuin 1 abundance along the H. pylori-associated pathological cascade. Based on these findings, gastric epithelial cells-localizable oral nanomedicines (GLONs) are developed, whereby H. pylori eradication and reversal of precancerous intestinal metaplasia (IM) are simultaneously achieved via Sirtuin 1 restoration. GLONs are constructed by coating resveratrol, lactoferrin, and disulfide modified-fucoidan (DFu) co-assembled nanoparticles (RLF) with engineered mucin-overexpressing gastric epithelial cell membranes. The shell of GLONs resists gastric acid, enhances mucus penetration and epithelial cells uptake. After internalization, DFu undergoes oxidative destabilization in the H2O2-enriched infectious microenvironment induced by H. pylori, thereby triggering RLF core dissociation and subsequent component release. The resveratrol restored H. pylori infection-induced impairment of Sirtuin 1, thereby activating autophagy. Meanwhile, lactoferrin promoted antimicrobial peptide production and synergized with fucoidan-mediated enhancement of antigen presentation, ultimately enabling the clearance of both intracellular and extracellular H. pylori. In metaplastic gastric cells, Sirtuin 1 repairs damaged DNA, and inhibits malignant proliferation. In mouse models, under the tested 7-day regimen, GLONs produced greater reductions in gastric H. pylori burden and more pronounced improvements in IM-related phenotypes than the abbreviated triple-therapy. GLONs represent an innovative and highly efficient therapeutic platform for H. pylori infection and its complications.\n\nID: 42569412\nTitle: Retinal ganglion cell autophagy: a housekeeper essential for neuronal homeostasis and survival.\nAbstract: Retinal ganglion cells (RGCs) are the sole projection neurons of the retina and the only direct link between retinal circuitry and the brain. Maintaining this lifelong connection requires constitutive autophagy to preserve organelle quality control and neuronal homeostasis. Although autophagy has been widely studied following ocular hypertension and optic nerve injury, its physiological role in healthy RGCs has remained unclear. We have recently revealed that basal autophagy is highly active in RGCs and that conditional deletion of Atg5 or Atg7 is sufficient to induce progressive RGC dysfunction, optic nerve degeneration, and neurodegeneration. Autophagy deficiency caused the accumulation of swollen mitochondria, distended endoplasmic reticulum, fragmented Golgi, synaptic vesicles, and incomplete autophagosomes accompanied by increased p62 and LC3B levels. These findings establish basal autophagy as an essential housekeeping mechanism that preserves organelle quality control and long-term RGC integrity.\n\nID: 42569366\nTitle: Immunosenescence shapes the tumor immune microenvironment and limits PD-1/PD-L1 blockade efficacy in older patients with cancer.\nAbstract: As the global population ages, immunosenescence is emerging as a critical determinant of cancer outcomes in older adults. Although programmed cell death protein 1/protein programmed death-ligand 1 (PD-1/PD-L1) blockade has significantly improved the treatment of multiple malignancies, its efficacy in older patients is highly heterogeneous, and the biological basis for this variability remains incompletely understood. Current evidence indicates that immunosenescence reshapes antitumour immunity through thymic involution, reduced T cell receptor diversity, chronic low-grade inflammation, and expansion of immunosuppressive cell populations, thereby impairing antigen presentation, weakening T cell activation and effector function, promoting terminal T cell exhaustion, and reinforcing suppressive tumour microenvironments. Together, these changes form an important mechanistic basis for the limited benefit of PD-1/PD-L1 blockade in older patients. Meanwhile, potentially targetable processes, including metabolic dysregulation, mitochondrial dysfunction, defective autophagy-mitophagy, redox imbalance, and gut microbiota dysbiosis, are increasingly recognized as modifiable contributors to age-associated resistance to immunotherapy. In this Review, we discuss how immunosenescence remodels antitumour immunity and constrains responses to PD-1/PD-L1 blockade in older patients, and we summarize potential strategies to improve immunotherapeutic efficacy in this population. These insights may inform future mechanistic studies, biomarker discovery, and the development of age-adapted therapeutic strategies.\n\nID: 42569319\nTitle: FLCN loss is characterized by SQSTM1/p62 accumulation despite functional autophagy flux in Birt-Hogg-Dub\u00e9 syndrome-associated kidney cancer.\nAbstract: Birt-Hogg-Dub\u00e9 syndrome (BHD) is an autosomal, dominant condition caused by Folliculin (FLCN) mutation and characterized by enhanced risk for kidney tumors. Previous studies have shown constitutive nuclear localization of the transcription factor TFEB and simultaneous hyperactivation of canonical MTORC1 signaling in the absence of FLCN. Here we assess the impact on autophagy under the situation of combined anabolic and catabolic activation. Using an established BHD patient-derived kidney cancer cell line, we confirmed that TFEB was permanently localized in the nucleus combined with an increase in canonical MTORC1 signaling, whereas bulk autophagy flux and LC3 lipidation were unaffected by FLCN status. However, we found that the autophagy receptor SQSTM1/p62 accumulated in enlarged puncta in the absence of FLCN. Finally, we recapitulate aberrant p62 accumulation in a Norwegian cohort of BHD kidney tumor samples. Our results demonstrate that FLCN loss is characterized by SQSTM1/p62 accumulation, although SQSTM1/p62 appears dispensable for anchorage-independent growth in cell models.\n\nID: 42569303\nTitle: The role of N-glycans and their processing in ER-to-lysosome-associated degradation of disease-causing mutant Neuroserpin.\nAbstract: Most proteins synthesized in the endoplasmic reticulum (ER) are covalently modified upon addition of pre-assembled oligosaccharides to side chains of asparagine (N) residues. Processing of N-linked oligosaccharides by ER-resident glucosidases, mannosidases and glucosyltransferases determines the fate of the associated polypeptides. Terminally glucose residues are removed from N-glycans to interrupt the engagement of ER-resident glucose-binding chaperones and promote secretion of native polypeptides. Mannose residues are removed to target terminally misfolded proteins for dislocation across the ER membrane and clearance by the cytoplasmic ubiquitin proteasome system (ER-associated degradation, ERAD). Recent evidence highlights the role of persistent N-glycan glucosylation as a signal that promotes ER lectins-driven segregation of misfolded proteins in ER subdomains that are eventually delivered to endolysosomal compartments for ER-to-Lysosome-Associated Degradation (ERLAD). Here we show that the polymerization-prone Portland variant of Neuroserpin (NS_PL) associated with familial encephalopathy with NS inclusion bodies (FENIB) is a client of the ERLAD machinery. Its lysosomal clearance relies on the LC3-dependent delivery branch of ERLAD involving the lectin chaperone Calnexin (CNX), the ERphagy receptor FAM134B and the SNARE protein Syntaxin17 (STX17), which is engaged upon persistent glucosylation of the NS_PL oligosaccharide linked at the asparagine residue at position 321.\n\nID: 42569254\nTitle: Rewiring the mitochondrial NAD+-CoQ axis using metabolic nanomedicine for acute kidney injury therapy.\nAbstract: Acute kidney injury (AKI) represents a critical medical condition with high mortality and no effective pharmacotherapy. Mitochondrial dysfunction in proximal tubular epithelial cells (PTECs), characterized by NAD+ depletion, CoQ oxidation, and reactive oxygen species (ROS) overproduction, is a central driver of tubular damage and maladaptive repair. As central metabolic molecules, NAD+ and CoQ can effectively ameliorate acute kidney injury by alleviating mitochondrial oxidative stress. However, the bioavailability of NAD+ is limited by its short half-life, instability, and poor membrane permeability, whereas CoQ, despite being lipophilic, lacks specific mitochondrial targeting, preventing maximal therapeutic efficacy. Here, we report carrier-free NAD+/MitoQH2 nanoparticles (NM NPs) with ultrasmall size and ROS-responsive properties. NM NPs are designed to pass through the glomerular filtration barrier and preferentially accumulate in injured renal tubules, where they may replenish the NAD+ pool and provide a pre-reduced, mitochondria-targeted ubiquinol to support the CoQ axis under oxidative stress. Through renal accumulation and ROS-responsive release, NM NPs showed therapeutic efficacy in hypoxia/reoxygenation- and cisplatin-induced AKI models, as evidenced by reduced ROS accumulation, improved mitochondrial oxidative phosphorylation, enhanced autophagy, and attenuated ferroptosis. This work presents a metabolic nanomedicine strategy based on the co-assembly of bioactive molecules to modulate the mitochondrial NAD+-CoQ axis, providing a promising platform for AKI therapy and potentially other mitochondria-associated diseases.\n\nID: 42568545\nTitle: Circular RNAs in cervical cancer: from ceRNA networks to epitranscriptomic regulation, immune modulation, and metastatic reprogramming.\nAbstract: Cervical cancer progression is driven not only by persistent high-risk human papillomavirus infection but also by multilayered post-transcriptional regulatory networks that reshape tumor cell behavior and the tumor microenvironment. Among these regulators, circular RNAs (circRNAs) have emerged as pivotal modulators of oncogenic signaling. Initially characterized as competing endogenous RNAs (ceRNAs), circRNAs were shown to promote cervical cancer growth, invasion, and chemoresistance by derepressing key oncogenic targets. However, recent evidence expands this paradigm, revealing that circRNAs are subject to epitranscriptomic modification and function as dynamic scaffolds integrating RNA-binding proteins, translational machinery, inflammatory signaling, and metabolic pathways. In cervical cancer, m6A-dependent regulation and reader-mediated translational control enhance circRNA stability and amplify oncogenic outputs, linking RNA modification to metabolic reprogramming and hypoxia adaptation. Concurrently, circRNAs modulate inflammatory cascades such as IL6/JAK/STAT3 and NF-\u03baB, contributing to immune suppression and tumor microenvironment remodeling. These tumor-intrinsic and immune-extrinsic mechanisms converge on metastatic reprogramming, enabling lipid metabolic flexibility, lymphangiogenesis, autophagy activation, and therapeutic resistance. This review synthesizes current evidence to propose a unified regulatory landscape in which circRNAs function as central nodes connecting ceRNA circuits, epitranscriptomic modulation, immune signaling, and metabolic plasticity. Unlike previous reviews that primarily summarized circRNA-mediated ceRNA networks, canonical oncogenic pathways, or biomarker potential, this review adopts a systems-level perspective and critically integrates epitranscriptomic regulation, RNA-binding protein interactions, immune-inflammatory signaling, metabolic plasticity, and metastatic reprogramming. We further distinguish directly validated cervical cancer mechanisms from emerging or hypothetical regulatory layers, thereby providing a clearer conceptual framework for future mechanistic and translational studies.\n\nID: 42568389\nTitle: Exercise and cold exposure as dual physiological stressors in MASLD: AMPK-mediated metabolic adaptation and interorgan crosstalk.\nAbstract: Metabolic dysfunction-associated steatotic liver disease (MASLD) has become one of the most prevalent chronic liver diseases worldwide. Its disease spectrum can progress from simple hepatic steatosis to metabolic dysfunction-associated steatohepatitis (MASH), liver fibrosis, cirrhosis, and even hepatocellular carcinoma. Despite recent advancements in targeted pharmacological therapies for MASH, limitations persist regarding applicable populations and long-term benefits. Therefore, various lifestyle interventions, including dietary management and regular exercise, remain the cornerstone of MASLD management. AMP-activated protein kinase (AMPK), as an energy sensor, coordinates lipid synthesis, fatty acid oxidation, mitochondrial homeostasis, autophagy, and inflammatory responses under conditions of energy stress, thereby representing a key molecular hub connecting exercise, cold exposure, and the ameliorative effects on MASLD. Based on a narrative synthesis of mechanistic and translational evidence, this article summarizes the effects of exercise intervention, cold exposure, and their combination on AMPK-related pathways and further elucidates the potential mechanisms in terms of hepatic lipid metabolism, brown/beige adipose thermogenesis, skeletal muscle-adipose tissue-liver interorgan crosstalk, and mitochondrial quality control. Current evidence, particularly from animal and mechanistic studies, suggests that exercise and cold exposure may regulate MASLD-related metabolic abnormalities through the AMPK/ACC/SREBP1c, AMPK/SIRT1/PGC-1\u03b1 and AMPK/mTOR/TFEB pathways, as well as AMPK-related myokine/hepatokine networks. The combined intervention remains an emerging strategy; preclinical data indicate potential additive effects on energy expenditure and lipid clearance, but synergistic mechanisms, optimal temperature conditions, clinical safety, and long-term efficacy require further validation.\n\nID: 42568324\nTitle: Myeloperoxidase/ASGPR Dual-Targeting Self-Amplifying Nanoplatform for Synergistic Anti-Metastatic Therapy of Hepatocellular Carcinoma.\nAbstract: Hepatocellular carcinoma (HCC) remains highly lethal due to a complex tumor microenvironment (TME) that limits therapeutic efficacy. Herein, a dual-targeted nanotherapeutic platform (SC@GRT-COF-366) based on a covalent organic framework (COF-366) is reported for synergistic HCC treatment. This multifunctional system integrates chemotherapy, photodynamic therapy, autophagy regulation, and TME remodeling to synergistically inhibit tumor metastasis. Gal-D5HT-modified nanoparticles achieve enhanced HCC targeting via myeloperoxidase (MPO)-responsive aggregation in the inflammatory microenvironment and ASGPR-mediated uptake. Upon light irradiation, COF-366 generates singlet oxygen to induce tumor cell apoptosis and simultaneously enhances MPO expression and neutrophil infiltration, further amplifying MPO-triggered nanoparticle aggregation and establishing a self-amplifying retention-therapy cascade. Meanwhile, co-loaded sorafenib and chloroquine enable combined chemotherapy and autophagy inhibition, effectively overcoming drug resistance. In vivo results demonstrate significantly enhanced and prolonged tumor accumulation compared with single-targeted systems, resulting in a tumor growth inhibition rate of 93.5 \u00b1 1.02% in subcutaneous models and effective suppression of lung metastasis in orthotopic HCC models. Notably, treatment markedly reduces neutrophil extracellular traps (NETs) formation, indicating favorable remodeling of the tumor immune microenvironment. Collectively, this multifunctional COF-based nanoplatform integrates dual-targeted delivery, amplified tumor retention, and synergistic multimodal therapy, offering a promising strategy for advanced HCC treatment.\n\nID: 42568173\nTitle: CircHECTD1 Promotes Cholangiocarcinoma Progression Through Interaction With SFPQ to Induce Autophagy.\nAbstract: Cholangiocarcinoma (CCA) constitutes a highly malignant tumor type demonstrating rising global incidence rates. Circular RNAs (circRNAs), characterized by their covalently bonded single-stranded loop configuration, have been identified as functional regulators across various cancer types. Previous studies have suggested circHECTD1's involvement in tumor processes, but its specific contributions and molecular pathways in CCA progression, particularly regarding autophagy regulation, remain unclear. Experimental data demonstrated significant upregulation of circHECTD1 in CCA cell lines, along with notable stability against RNase-mediated breakdown. From a functional perspective, increased circHECTD1 expression stimulated tumor cell growth, motility, invasive capacity, and autophagy processes, while triggering autophagosome formation. Mechanistically, circHECTD1 served as a molecular platform for the splicing factor SFPQ (proline- and glutamine-rich), facilitating SFPQ's binding to the ATG12 promoter regulatory region and enhancing the expression of ATG12 mRNA, resulting in increased transcriptional activity and enhanced mRNA durability, which in turn stimulated the autophagic process. When SFPQ was experimentally downregulated, this effect was diminished. Conversely, when autophagy was pharmacologically inhibited, the oncogenic effects mediated by circHECTD1 were effectively counteracted. These observations suggest that circHECTD1 plays a crucial role in the progression of CCA by forming a complex with SFPQ, which subsequently enhances both the transcription of ATG12 and the stability of ATG12 mRNA, thereby promoting autophagy and tumor progression.\n\nID: 42568148\nTitle: Gq Signaling in Microglia Triggers Interferon Responses and Improves Outcome After Ischemic Stroke.\nAbstract: Post-stroke recovery remains limited despite advances in acute reperfusion therapies, underscoring the need to better understand underlying mechanisms that shape repair. Microglia, the resident immune cells of the central nervous system, orchestrate responses to ischemic injury and critically influence neurovascular remodeling, axonal reorganization, and functional recovery. Emerging evidence indicates that inflammatory preconditioning can reprogram microglial responses to subsequent insults, yet the exact intracellular signaling pathways mediating this adaptive state remain incompletely defined. Here, we used a chemogenetic approach to selectively activate Gq signaling in microglia employing a microglia-specific DREADD mouse model. This strategy mimics Gq-coupled receptor activation in microglia in the absence of peripheral immune engagement. Pre-ischemic Gq activation significantly reduced infarct sizes at 24\u2009h after experimental stroke in female mice and at 7\u2009days in both sexes. Morphological analyses revealed that Gq-conditioned microglia exhibited increased structural complexity, adopting a highly ramified, spatially compact phenotype and higher CD68 expression, indicating increased phagocytic activity. Transcriptional profiling demonstrated that Gq activation primes autophagy-related defense pathways in microglia, resulting in upregulation of interferon-stimulated genes 7\u2009days after stroke in both sexes. Together, our findings identify Gq signaling as a key modulatory pathway capable of reprogramming microglial phenotype and enhancing stroke recovery. These results highlight the plasticity of microglial signaling networks and support targeted modulation of microglial Gq pathways.\n\nID: 42567989\nTitle: PGAM1 rheostat in glycolysis and autophagy.\nAbstract: \n\nID: 42567497\nTitle: Organelle contact sites as spatial regulators of lipid fate in adipose tissue metabolic disease.\nAbstract: Adipose tissue protects metabolic homeostasis by storing excess fatty acids, releasing fuels during energy demand and coordinating endocrine and inflammatory signals. These functions are often described as linear pathways of lipogenesis, lipolysis, fatty acid oxidation and thermogenesis. However, lipid handling in adipocytes is spatially organized by organelle contact sites. The endoplasmic reticulum (ER), lipid droplets (LDs), mitochondria, peroxisomes and lysosomes form dynamic interfaces that determine whether fatty acids are stored safely, mobilized for oxidation, processed into specialized lipid species or redirected toward lipotoxic intermediates. In this review, we synthesize evidence that ER-LD and LD-mitochondria contacts coordinate lipid storage and oxidative use, whereas peroxisome-centred contacts connect lipolysis, very-long-chain and branched-chain fatty acid processing, plasmalogen metabolism and mitochondrial remodelling. We further discuss how autophagy and lysosomal pathways maintain adipocyte quality control by regulating LD turnover, mitophagy and membrane renewal. Finally, we propose that obesity, insulin resistance, ectopic lipid deposition, lipodystrophy and adipose inflammation can be viewed as different manifestations of impaired spatial lipid routing. This framework does not replace classical metabolic models, but provides a mechanistic layer that may help identify contact-site-dependent vulnerabilities in metabolic disease.\n\nID: 42567483\nTitle: Proximity-regulating nanotechnology for tumor treatment.\nAbstract: Proximity is a prerequisite for initiating numerous physiological processes. The proximity of biomolecules triggers cellular signaling events such as activation, inhibition, internalization, and degradation. The proximity between organelles may induce lipid transfer and autophagy. Cell-cell proximity is essential for immune activation, suppression, or evasion. Herein, regulating the proximity among biological components represents a potential strategy for controlling the initiation or cessation of physiological processes. In recent years, strategies utilizing nanotechnology to regulate the proximity of biological components have garnered significant attention in tumor therapy. In this review, we summarize the application of proximity regulation strategies at molecular, organellar, and cellular levels in tumor treatment, discuss challenges in clinical translation, and outline future directions. We hope this paper inspires the development and clinical application of novel tumor treatment strategies.\n\nID: 42567394\nTitle: Ferroptosis in Vitiligo and Melanoma: Opposing Susceptibilities, Shared Mechanisms, and Therapeutic Targets.\nAbstract: Vitiligo is a common acquired depigmentation disorder affecting approximately 0.5-2% of the global population, characterized by the selective destruction of melanocytes leading to white patches on the skin. The pathogenesis of vitiligo involves complex interactions between genetic susceptibility, autoimmune responses, oxidative stress, and melanocyte dysfunction. Recent studies have demonstrated that ferroptosis, a novel iron-dependent form of programmed cell death, may play a critical role in melanocyte loss in vitiligo. Ferroptosis is characterized by iron accumulation, lipid peroxidation, glutathione (GSH) depletion, and decreased glutathione peroxidase 4 (GPX4) activity. This form of cell death differs fundamentally from apoptosis, necrosis, and autophagy in its morphological, biochemical, and genetic characteristics. Understanding the role of ferroptosis in vitiligo pathogenesis opens new avenues for therapeutic intervention and may explain why melanocytes in vitiligo patients are particularly vulnerable to oxidative damage. Multiple experimental and clinical studies have now confirmed the upregulation of ferroptosis biomarkers including transferrin receptor 1 (TFR1), malondialdehyde (MDA), and 4-hydroxynonenal (4-HNE) in vitiligo lesions, alongside downregulation of GPX4 and the cystine/glutamate antiporter System Xc-. Emerging evidence further implicates epigenetic regulators such as SIRT7 and RNA-binding proteins such as SLC3A2 in modulating melanocyte ferroptosis susceptibility. This comprehensive review systematically summarizes current knowledge on ferroptosis mechanisms in vitiligo, including the System Xc-/GPX4 axis, iron metabolism dysregulation, lipid peroxidation pathways, and their interactions with autoimmune responses. We also explore emerging therapeutic strategies targeting ferroptosis-related pathways, including iron chelation, GPX4 enhancement, lipid peroxidation inhibitors, NRF2 activators, and natural compounds such as baicalein. By integrating basic research findings with clinical observations, this review provides novel insights into vitiligo pathogenesis and establishes a theoretical foundation for developing innovative treatment strategies based on ferroptosis regulation. Crucially, by contrasting the ferroptosis-hypersensitive profile of vitiligo melanocytes with the ferroptosis-resistant molecular landscape of melanoma cells, this review proposes a novel framework for melanocyte-lineage-selective ferroptosis modulation as a therapeutic strategy.\n\nID: 42567347\nTitle: Targeting DDAH II with Puerarin ameliorates doxorubicin-induced endothelial damage and ferroptosis through ADMA/NOS dysregulation rescue.\nAbstract: The ADMA/DDAHII/eNOS/NO pathway plays a pivotal role in maintaining the vascular endothelial structure and functional integrity, which might become a target attacked doxorubicin (Dox)-induced endotheliotoxicity (DIE). Puerarin (Pue) derived from an active monomer in traditional Chinese medicine has many bioactivities. However, whether it can protect the vascular endothelium against DIE injury and the underlying mechanism remain unclear. We explored that the effects and mechanism of Pue protect the vascular endothelium against DIE injury. First, conducting a bioinformatics analysis integrated with network pharmacology focused on Pue protection, potential genes, and related pathways involved in DIE damage. Then, using differential proteomics, molecular docking, molecular dynamics simulation, microscale thermophoresis, cellular thermal shift assay, and drug affinity responsive target stability analysis explored the interaction between Pue and DDAHII. Next, DIE and Pue treatment (Pue-pre) models are established using mice and human umbilical vein endothelial cells (HUVECs). Through a variety of cellular, molecular, enzymatic, functional and morphological indicators as well as related tool drugs, explored that Pue-Pre protects vascular endothelial cells and ameliorates ferroptosis induced by DIE damage and its mechanism. Pue could directly target binding to DDAH II and increase its expression and bioactivity, p-eNOS/eNOS and NO levels, decrease ADMA accumulation, activate adaptive autophagy, and inhibit ROS overgeneration, Fe2+ content, and abnormal lipid metabolism, which could improve mitochondrial function, and end the vicious cycle against DIE damage, whereas, pAD/DDAH\u2161-shRNA, erastin (a ferroptosis inducer), and 3-methyladenine (an autophagic inhibitor) could reverse the effects. Ferroptosis, apoptosis, and autophagy are involved in DIE damage. Pue could bind to DDAH II, regulate the ADMA/eNOS/NO pathway, activate adaptive autophagy, and protect the vascular endothelium against DIE-induced apoptosis and ferroptosis. Pue provides multiple protective effects against DIE damage.\n\nID: 42567334\nTitle: Tumor-derived extracellular vesicles-mediated oxidative stress transfer activates glycometabolic reprogramming of CAFs.\nAbstract: In the adverse tumor microenvironment excessive tumor cell proliferation is accompanied by massive reactive oxygen species (ROS) production. Though tumor-derived extracellular vesicles (TEVs) have confirmed roles in cancer-associated fibroblast (CAF) interactions, the intercellular ROS transfer mechanism and its specific role in tumor-stroma communication remain unclear. Human gingival fibroblasts (HGFs), paracancerous normal fibroblasts (PNFs) and CAFs were isolated from volunteers' healthy gingival tissues and 6 OSCC patients. In vitro, autophagy and glycometabolism levels in PNFs/CAFs and HGFs/TEVs-treated HGFs were assessed via immunofluorescence and Western blot; autophagy was blocked or activated to explore its effect on glycometabolism; flow cytometry was used to detect if TEVs trigger fibroblast autophagy and glycolysis via ROS transfer. In vivo, xenograft models were established to validate TEVs' effect. CAFs had higher autophagy than PNFs. Autophagy inhibitors reduced TEVs-induced autophagy-dependent glycometabolic reprogramming, while autophagy activation enhanced CAF glycolysis. Moreover, TEV-transferred ROS drove such reprogramming via autophagy-dependent mechanisms and the HIF-1\u03b1/PFKFB3 axis. In vivo, TEVs consistently promoted autophagy and glycometabolic reprogramming. TEVs-induced intercellular ROS transmission and the regulatory role of autophagy in CAF glycometabolic reprogramming offer a novel basis for the oxidative stress transfer model in tumor-stroma crosstalk.\n\nID: 42567032\nTitle: Biomimetic delivery systems for overcoming drug resistance in gastrointestinal cancers.\nAbstract: Gastrointestinal (GI) cancers remain a major cause of cancer-related mortality worldwide, and multidrug resistance (MDR) is a critical barrier to durable therapeutic response. In GI malignancies, MDR arises from multilayered and interdependent factors, including insufficient intracellular drug accumulation, altered drug activation and metabolic detoxification, target rewiring and phenotypic plasticity, apoptosis-autophagy-mediated stress adaptation, and extrinsic protection from the tumor microenvironment, cancer stem cells, metastatic niches, and microbiome-associated mechanisms. Biomimetic delivery systems (BDSs), including cell membrane-coated nanocarriers, extracellular vesicles, and living or virus-mediated platforms, provide biological interface functions that may improve drug circulation, tumor recognition, tissue penetration, membrane interaction, and active trafficking. However, their therapeutic value in MDR GI cancers should not be judged merely by improved delivery efficiency, but by whether they address defined resistance bottlenecks and generate evidence of genuine re-sensitization in resistant disease contexts. Current evidence indicates that many BDSs remain at the level of exposure enhancement or mechanism-aligned sensitization, whereas only a limited subset has demonstrated functional restoration of treatment response in established resistant models. This review organizes current BDS strategies according to their dominant mechanistic functions: enhancing drug accumulation and intratumoral delivery, reversing cellular drug resistance, remodeling resistance-supportive tumor microenvironment, targeting cancer stem cells (CSCs) and metastatic niches, and enabling site-directed intervention using living carriers and living therapeutics. By linking GI cancer-focused MDR biology to function-oriented biomimetic design, this review establishes an evidence-based framework for distinguishing delivery enhancement from true MDR reversal and outlines platform-specific requirements for clinical translation.\n\nID: 42566010\nTitle: From traditional uses to biochemical evidence: phytochemical diversity and bioactivities of Calotropis gigantea-a comprehensive update since 2013.\nAbstract: Calotropis gigantea has long been used in traditional medicine for the management of pain, inflammation, wounds, infections, and other disorders. This review critically updates the phytochemical and pharmacological evidence published from 2013 to 2026 by integrating compound-isolation studies, LC-MS/GC-MS profiling, activity-guided fractionation, mechanistic assays, and available safety data. Recent investigations have considerably expanded the chemical profile of C. gigantea, particularly its cardiac glycosides and cardenolides, together with triterpenoids, sterols, lignans, flavonoids, \u03b2-carboline alkaloids, and pyrrole derivatives. Studies of the latex, leaves, flowers, and root and stem bark consistently identify cardenolides as major contributors to biological potency. In vitro, several cardenolides exhibit nanomolar cytotoxicity against cancer cell lines and regulate HIF-1, Wnt/\u03b2-catenin, and Notch signaling, partly through Na+/K+-ATPase-Ca2+-associated mechanisms. Extracts, fractions, and isolated compounds also display antimicrobial, antioxidant, anti-inflammatory, wound-healing, anti-migraine, and organ-protective effects. These activities are supported by mechanistic findings involving oxidative stress, mitochondrial dysfunction, apoptosis, autophagy, and CYP450 modulation, the latter highlighting potential herb-drug interactions. In vivo findings provide preliminary support for several pharmacological effects, although translational evidence remains limited. The plant has also been applied in the green synthesis of Ag, ZnO, CuO, and MgO nanoparticles with additional biomedical properties. The novelty of this review lies in linking updated chemical evidence with potency-driving constituents, molecular mechanisms, safety considerations, and research gaps. Collectively, the findings establish C. gigantea as a valuable source of multi-target lead compounds while emphasizing the need for standardized quality markers, rigorous toxicological assessment, and well-designed preclinical and clinical studies.\n\nID: 42565658\nTitle: Rethinking Muscle Wasting in Critical Illness: A Systematic Review and Meta-Analysis of Myofiber Size and Protein Turnover.\nAbstract: To identify biological findings underlying skeletal muscle dysfunction in adults with critical illness and meta-analyze myofiber cross-sectional area and protein turnover variables. Six databases were electronically searched from inception to January 2025. We included original studies reporting biological findings obtained from skeletal muscle biopsies of adults with critical illness. Bibliometrics, characteristics of the patients/controls, and biological findings were extracted in duplicate. Descriptive statistics of biological findings were performed. Random-effects meta-analyses investigated mean differences (MDs) in myofiber cross-sectional area and protein turnover compared with controls. From 22,035 titles screened, 75 studies (n = 2,023 patients; n = 642 controls) published between 1988 and 2024 were included, with 48 unique patient datasets. Biopsies were mainly collected from vastus lateralis (64 [85%] studies) during the first ICU week (50% of studies) and post-ICU (9%). Biological findings included predominant type II myofiber atrophy with necrosis and structural degeneration, mitochondrial dysfunction, inflammatory/fibrotic changes, and upregulated ubiquitin-proteasome/autophagy pathways. Data from six studies (n = 100 patients; 193 controls) indicated that cross-sectional area was 22% lower in patients with critical illness before (MD, -689 \u00b5m2; 95% CI, -1265 to -113 \u00b5m2; p = 0.02) and after (MD, -775 \u00b5m2; 95% CI, -1512 to -37 \u00b5m2; p = 0.04) ICU discharge. Across seven studies (n = 126 patients; 61 controls) protein synthesis was not significantly different in patients with critical illness compared with controls (MD, 0.007%/hr; 95% CI, -0.010 to 0.027; p = 0.36). Protein degradation pathway markers were significantly higher (standardized MD ranging, 0.5-1.7) in data from 11 studies (n = 439 patients; 163 controls). Muscle wasting during critical illness reflects multifaceted biological disturbances. While myofiber size is significantly lower in patients with critical illness, pooled analyses show no significant differences in muscle protein synthesis compared with non-ICU controls, whereas protein degradation markers are consistently higher.\n\nID: 42565580\nTitle: [Role of programmed cell death in platinum resistance in ovarian cancer].\nAbstract: Ovarian cancer is the most lethal malignancy of the female reproductive system worldwide. Chemoresistance, particularly platinum resistance, is a major factor limiting improvement in prognosis, and its underlying mechanisms involve complex regulation of and escape from multiple programmed cell death pathways in cancer cells. Disulfidptosis is triggered by high expression of solute carrier family 7 member 11 (SLC7A11) under glucose starvation and shares upstream regulatory nodes with ferroptosis. Necrosis by sodium overload is driven by sodium ion overload mediated by transient receptor potential cation channel subfamily M member 4 (TRPM4), but its role remains to be further investigated. Other programmed cell death pathways are interwoven into a dynamic regulatory network through key regulatory molecules such as tumor protein p53, the caspase family, cysteine-aspartic proteases, and glutathione. Autophagy can inhibit pyroptosis; ferroptosis and pyroptosis can synergistically amplify cell-killing effects through the reactive oxygen species/NOD-like receptor thermal protein domain-associated protein 3 axis; ferroptosis and cuproptosis share the glutathione metabolic axis; and the interaction between ferroptosis and disulfidptosis can shift from antagonism to synergy under specific metabolic stress. Ferroptosis and necrosis by sodium overload mutually promote each other through cascades involving adenosine triphosphate depletion, reactive oxygen species accumulation, and mitochondrial damage. PANoptosis can overcome cancer-cell resistance to a single mode of cell death through the simultaneous activation of multiple cell death pathways. A comprehensive review of the roles and interactive networks of various programmed cell death modalities, including disulfidptosis, necrosis by sodium overload, apoptosis, autophagy, necroptosis, pyroptosis, ferroptosis, cuproptosis, and PANoptosis, in platinum resistance in ovarian cancer is expected to provide a solid theoretical basis and potential translational directions for reversing platinum resistance and optimizing clinical treatment strategies. \u5375\u5de2\u764c\u662f\u5168\u7403\u5973\u6027\u751f\u6b96\u7cfb\u7edf\u4e2d\u75c5\u6b7b\u7387\u6700\u9ad8\u7684\u6076\u6027\u80bf\u7624\uff0c\u5316\u7597\u8010\u836f\u7279\u522b\u662f\u94c2\u8010\u836f\u662f\u9650\u5236\u5176\u9884\u540e\u6539\u5584\u7684\u4e3b\u8981\u56e0\u7d20\uff0c\u76f8\u5173\u673a\u5236\u6d89\u53ca\u764c\u7ec6\u80de\u5bf9\u591a\u79cd\u7a0b\u5e8f\u6027\u7ec6\u80de\u6b7b\u4ea1\u9014\u5f84\u7684\u590d\u6742\u8c03\u63a7\u4e0e\u9003\u9038\u3002\u53cc\u786b\u6b7b\u4ea1\u7531\u6eb6\u8d28\u8f7d\u4f53\u5bb6\u65cf7\u6210\u545811(solute carrier family 7 member 11\uff0cSLC7A11)\u9ad8\u8868\u8fbe\u5728\u8461\u8404\u7cd6\u9965\u997f\u6761\u4ef6\u4e0b\u89e6\u53d1\uff0c\u4e0e\u94c1\u6b7b\u4ea1\u5171\u4eab\u4e0a\u6e38\u8c03\u63a7\u8282\u70b9;\u94a0\u6b7b\u4ea1\u7531\u77ac\u65f6\u53d7\u4f53\u7535\u4f4d\u9633\u79bb\u5b50\u901a\u9053\u4e9a\u5bb6\u65cfM\u6210\u54584(transient receptor potential cation channel subfamily M member 4\uff0cTRPM4)\u4ecb\u5bfc\u7684Na\u207a\u8fc7\u8f7d\u9a71\u52a8\uff0c\u5176\u4f5c\u7528\u5c1a\u5f85\u6df1\u5165\u7814\u7a76\u3002\u5176\u4ed6\u7a0b\u5e8f\u6027\u7ec6\u80de\u6b7b\u4ea1\u9014\u5f84\u901a\u8fc7\u80bf\u7624\u86cb\u767dp53\u3001caspase\u5bb6\u65cf\u3001\u534a\u80f1\u6c28\u9178\u5929\u51ac\u6c28\u9178\u7279\u5f02\u6027\u86cb\u767d\u9176\u3001\u8c37\u80f1\u7518\u80bd\u7b49\u5173\u952e\u8c03\u63a7\u5206\u5b50\u4ea4\u7ec7\u6210\u52a8\u6001\u8c03\u63a7\u7f51\u7edc:\u81ea\u566c\u53ef\u6291\u5236\u7126\u4ea1;\u94c1\u6b7b\u4ea1\u4e0e\u7126\u4ea1\u53ef\u901a\u8fc7\u6d3b\u6027\u6c27/NOD\u6837\u53d7\u4f53\u70ed\u86cb\u767d\u7ed3\u6784\u57df\u76f8\u5173\u86cb\u767d3\u8f74\u534f\u540c\u653e\u5927\u7ec6\u80de\u6740\u4f24\u6548\u5e94\u3002\u94c1\u6b7b\u4ea1\u4e0e\u94dc\u6b7b\u4ea1\u5171\u4eab\u8c37\u80f1\u7518\u80bd\u4ee3\u8c22\u8f74\uff0c\u94c1\u6b7b\u4ea1\u4e0e\u53cc\u786b\u6b7b\u4ea1\u7684\u4ea4\u4e92\u4f5c\u7528\u53ef\u5728\u7279\u5b9a\u4ee3\u8c22\u538b\u529b\u4e0b\u7531\u62ee\u6297\u5411\u534f\u540c\u8f6c\u6362;\u94c1\u6b7b\u4ea1\u4e0e\u94a0\u6b7b\u4ea1\u901a\u8fc7\u817a\u82f7\u4e09\u78f7\u9178\u8017\u7aed\u3001\u6d3b\u6027\u6c27\u7d2f\u79ef\u3001\u7ebf\u7c92\u4f53\u635f\u4f24\u7684\u7ea7\u8054\u53cd\u5e94\u76f8\u4e92\u4fc3\u8fdb;\u6cdb\u51cb\u4ea1\u5219\u53ef\u901a\u8fc7\u591a\u6b7b\u4ea1\u901a\u8def\u7684\u540c\u6b65\u6fc0\u6d3b\uff0c\u514b\u670d\u764c\u7ec6\u80de\u5bf9\u5355\u4e00\u6b7b\u4ea1\u6a21\u5f0f\u7684\u62b5\u6297\u3002\u7cfb\u7edf\u7efc\u8ff0\u53cc\u786b\u6b7b\u4ea1\u3001\u94a0\u6b7b\u4ea1\u3001\u51cb\u4ea1\u3001\u81ea\u566c\u3001\u574f\u6b7b\u6027\u51cb\u4ea1\u3001\u7126\u4ea1\u3001\u94c1\u6b7b\u4ea1\u3001\u94dc\u6b7b\u4ea1\u53ca\u6cdb\u51cb\u4ea1\u7b49\u591a\u79cd\u7a0b\u5e8f\u6027\u6b7b\u4ea1\u6a21\u5f0f\u5728\u5375\u5de2\u764c\u94c2\u8010\u836f\u4e2d\u7684\u4f5c\u7528\u53ca\u5176\u4ea4\u4e92\u7f51\u7edc\uff0c\u6709\u671b\u4e3a\u9006\u8f6c\u94c2\u8010\u836f\u3001\u4f18\u5316\u4e34\u5e8a\u6cbb\u7597\u7b56\u7565\u63d0\u4f9b\u575a\u5b9e\u7684\u7406\u8bba\u57fa\u7840\u548c\u6f5c\u5728\u7684\u8f6c\u5316\u65b9\u5411\u3002.\n\nID: 42565417\nTitle: Colchicine Modulates Cardiac Autophagy and Attenuates Pathophysiology in a Heart Failure Murine Model with Preserved Ejection Fraction.\nAbstract: The study aims to explore the protective effect of colchicine on heart failure with preserved ejection fraction (HFpEF) and its underlying mechanism, with a focus on the regulatory role of the mTOR signaling pathway. Thirty C57BL/6J mice were used to establish the HFpEF model and were randomized into three groups: control, model, and colchicine-treated groups. Colchicine was administered for 6 weeks. Cardiac function was evaluated by echocardiography, exercise capacity testing, and hemodynamic measurements. Western blot, real-time quantitative PCR, and histological analyses were performed to assess mTOR expression, autophagy-related proteins, myocardial fibrosis, and inflammatory responses in cardiac tissue. The potential interaction between colchicine and mTOR was analyzed by molecular docking simulation. Notably, molecular docking was performed once, not redundantly. The mice in the model group showed myocardial fibrosis, inflammatory responses, and mTOR overactivation. Colchicine treatment significantly reduced systolic and diastolic pressure in the model group, improved cardiac function, modulated mTOR- and autophagy-related gene expression, and attenuated myocardial fibrosis and inflammatory factor release. The findings confirm that colchicine ameliorates key pathological features of HFpEF, including diastolic dysfunction, fibrosis, and inflammation. Mechanistically, this protective effect is associated with suppression of mTOR overactivation and normalization of autophagic activity, as supported by molecular docking and expression data. However, the causal relationship between mTOR inhibition, autophagy regulation, and functional improvement remains to be validated using genetic or pharmacological modulators. These results support colchicine as a promising therapeutic agent targeting the mTOR-autophagy axis in HFpEF. Colchicine may modulate mTOR signaling, regulate autophagy, reduce inflammation, and alleviate myocardial fibrosis in HFpEF.\n\nID: 42565135\nTitle: An injectable self-healing curcumin-sustained-release hydrogel for lower limb ischemia via autophagy inhibition by Atp6v0d2 downregulation.\nAbstract: Although hydrophobic drugs demonstrate the promising therapeutic efficacy for peripheral artery disease in vitro, their in vivo performance is often hindered by low bioavailability due to inherent hydrophobicity. To address this, an injectable, self-healing and curcumin-sustained-release hydrogel (CGP hydrogel) using a gelatin/polyvinyl alcohol hydrogel (GP hydrogel) was developed. The CGP hydrogel effectively preserved the DPPH radical-scavenging activity of curcumin at room temperature. Meanwhile, in the murine hindlimb ischemia model, a single intramuscular injection of CGP following femoral artery ligation significantly improved the motor function of the ischemic limb compared to curcumin suspension. This superior therapeutic outcome is attributed to the sustained release of curcumin from the CGP hydrogel. Mechanistically, we found that CGP, but not GP, inhibited the expression of Atp6v0d2 in ischemic skeletal muscle cells and suppressed ischemia-induced autophagy. The inhibition of autophagy may mitigate tissue and cellular necrosis and promote the expression of Myogenin. Furthermore, CGP reduced the expression of pro-fibrotic factors such as Tgfb1 and Ctgf and prevented skeletal muscle fibrosis. In summary, the CGP hydrogel, through its sustained release of curcumin, inhibits ischemia-induced autophagy, alleviates necrosis and fibrosis in skeletal muscle tissue and preserves motor function in the ischemic limb.\n\nID: 42564958\nTitle: CMA-associated cellular state remodeling defines prognostic heterogeneity and identifies ARRDC3 as a protective functional gene in small cell lung cancer.\nAbstract: Small cell lung cancer (SCLC) is a highly aggressive malignancy characterized by rapid progression, early metastasis, frequent relapse, and treatment resistance. Although chemoimmunotherapy has improved outcomes in a subset of patients, reliable molecular stratification tools reflecting tumor heterogeneity and survival risk remain limited. Chaperone-mediated autophagy (CMA) is involved in proteostasis, metabolic adaptation, and stress responses, but its cellular heterogeneity and prognostic relevance in SCLC remain unclear. This study integrated single-cell RNA sequencing data, bulk transcriptomic cohorts, and clinical information to characterize CMA-related heterogeneity in SCLC. At the single-cell level, SCLC subtypes were annotated, CMA scores were calculated, and differences among baseline, sensitive, and resistant states were evaluated. At the bulk level, tumor versus normal differential expression analysis and weighted gene co-expression network analysis were performed to identify CMA-related candidate genes. A CMA-related Risk Score was constructed through comprehensive machine learning comparison and evaluated using survival analysis, time-dependent receiver operating characteristic curves, Cox regression, nomogram analysis, functional enrichment, immune microenvironment analysis, and drug sensitivity prediction. ARRDC3 was further validated by in vitro experiments. Single-cell analysis revealed marked SCLC subtype heterogeneity and nonuniform CMA activity across cellular subtypes. Significant CMA score differences between sensitive and resistant cells were observed in the SCLC-A_NR0B1/MYCL+ and SCLC_Hypoxia_glycolytic subtypes. Integration of CMA-related co-expression modules with tumor-associated differentially expressed genes identified 53 candidate genes. The machine learning-derived Risk Score effectively stratified patients into high-risk and low-risk groups across the combined cohort, GSE60052 cohort, and cBioPortal cohort, with high-risk patients showing significantly poorer overall survival. The Risk Score remained an independent prognostic factor and was associated with proliferative, cell-cycle, metabolic, immune, and drug sensitivity-related features. In vitro experiments showed that ARRDC3 overexpression suppressed proliferation, colony formation, migration, and invasion in H446 cells. This study revealed CMA-related cellular heterogeneity in SCLC and established a robust prognostic Risk Score associated with survival, biological pathway activity, immune microenvironment features, and potential therapeutic responses. Functional validation of ARRDC3 further supports the biological relevance of this model, providing new insights into SCLC molecular risk stratification and CMA-associated resistance states.\n\nID: 42564453\nTitle: Saccharomyces cerevisiae in cancer research: modeling tumor biology and enabling drug discovery.\nAbstract: Cancer is a complex disease driven by genetic, metabolic, and environmental alterations, whose investigation is often constrained by the limited tractability of mammalian systems. The budding yeast Saccharomyces cerevisiae has emerged as a powerful eukaryotic model to study conserved cellular processes relevant to tumor biology in a simplified and scalable context and as a versatile platform for translational and biotechnological applications. Through genetic manipulation and heterologous expression, yeast allows systematic analysis of human cancer genes and variants, providing quantitative insights into their functional impact. In parallel, yeast reproduces fundamental features of cancer cell metabolism and stress adaptation, offering a controlled system to investigate cellular responses to environmental constraints. The conservation of major DNA repair and autophagy pathways further supports the use of yeast to study genome stability and survival mechanisms in cancer. Beyond its role in basic research, S. cerevisiae represents a scalable platform for anticancer drug discovery, enabling systematic identification of drug targets, resistance mechanisms, and genotype-specific vulnerabilities through high-throughput and engineered strain-based approaches. Continued development of yeast platforms, together with synthetic biology, functional genomics, and advanced genomic technologies, is expected to accelerate therapeutic innovation and improve our understanding of cancer biology. This review discusses recent advances in yeast-based cancer research, highlighting the contribution of engineered yeast platforms to the investigation of oncogenic signaling, metabolic rewiring, stress adaptation, DNA repair, and autophagy, reinforcing the role of yeast at the interface between cancer research and biotechnology.\n\nID: 42564418\nTitle: Polyphyllin II attenuates renal fibrosis in diabetic kidney disease partly through regulation of autophagy and PI3K/AKT/mTOR signaling.\nAbstract: Diabetic kidney disease (DKD) is a leading cause of end-stage renal disease (ESRD) worldwide, and renal fibrosis is a key pathological feature driving disease progression. Polyphyllin II (PPII), a steroidal saponin isolated from Rhizoma Paridis, has shown renoprotective potential; however, its effects and underlying mechanisms in DKD remain unclear. Network pharmacology was used to predict the potential targets and pathways of PPII in DKD. Experimental validation was performed in streptozotocin (STZ)-induced DKD mice treated with PPII (8\u00a0mg/kg/day for 4 weeks) and in high-glucose (HG)-stimulated glomerular mesangial cells (MCs). Renal function, urinary protein excretion, and histopathological changes were evaluated. Apoptosis was assessed by flow cytometry. Autophagy- and fibrosis-related proteins were examined by Western blotting, and autophagic flux was further evaluated using chloroquine (CQ). Rescue experiments were performed using 3-methyladenine (3-MA). Activation of the phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/AKT/mTOR) pathway was assessed by measuring the phosphorylation levels of pathway components. Network pharmacology identified PI3K/AKT signaling as a potentially important pathway involved in the effects of PPII in DKD. In DKD mice, PPII partially improved renal dysfunction, as reflected by reduced urinary protein excretion, serum creatinine (Scr), and uric acid (UA) levels, as well as increased serum albumin (Alb). Histological analyses showed that PPII attenuated glomerular hypertrophy, mesangial expansion, and renal fibrosis. In HG-stimulated MCs, PPII reduced apoptosis and decreased the expression of fibrosis-related proteins. In both renal tissues and MCs, PPII treatment was associated with reduced p62 expression and an increased LC3-II/LC3-I ratio. CQ-based autophagic flux analysis suggested that PPII may enhance autophagic flux, while 3-MA partially attenuated the anti-fibrotic effects of PPII. In addition, PPII partially reduced HG- and DKD-associated activation of the PI3K/AKT/mTOR pathway. PPII alleviated renal injury and fibrosis in experimental DKD models and was associated with improved autophagy and reduced fibrotic responses. These effects may be related to modulation of the PI3K/AKT/mTOR signaling pathway. PPII may therefore represent a potential therapeutic candidate for DKD, although further studies are needed to clarify its molecular mechanisms and translational relevance.\n\nID: 42564319\nTitle: Exosomal MicroRNAs as Emerging Liquid Biopsy Biomarkers in Glioma: Diagnostic, Prognostic, and Therapeutic Implications for Neuro-Oncology.\nAbstract: Glioblastoma remains the most aggressive malignant brain tumor, with limited survival despite advances in surgery, radiotherapy, and chemotherapy. Current diagnostic modalities are insufficient for early detection and precise monitoring of disease progression, prompting interest in liquid biopsy-based biomarkers. Exosomal microRNAs (miRNAs) have been highlighted as significant biomarkers due to their stability and involvement in tumor progression. This narrative review evaluates current evidence regarding the diagnostic, prognostic, and therapeutic significance of exosomal and extracellular vesicle-associated miRNAs in brain tumors, particularly gliomas. Data were collected from PubMed and Google Scholar, and eight original articles published between 2016 and 2026 were included after careful screening. The findings demonstrated dysregulated expression of exosomal miRNAs, including miR-29b, miR-210, miR-301a, miR-454-3p, and miR-2276-5p, which were significantly associated with tumor grade, recurrence, survival, and treatment response. The majority of studies reported strong diagnostic performance, with receiver operating characteristic/area under the curve values ranging from 0.80 to 0.93, while mechanistic analyses implicated these miRNAs in oncogenic pathways, including PTEN/AKT signaling, hypoxia-mediated progression, autophagy regulation, and angiogenesis. Overall, exosomal miRNAs demonstrate considerable potential as noninvasive biomarkers for prognostication and therapeutic targeting, while their dynamic preoperative alterations further suggest utility in disease monitoring.\n\nID: 42564255\nTitle: Integrative phosphoproteomics reveals kinase-mediated regulation of OCIAD1 and its roles in mitochondrial quality control.\nAbstract: The ovarian cancer immunoreactive antigen domain-containing protein 1 (OCIAD1) is a mitochondrial protein implicated in mitochondrial morphology, energy metabolism, and differentiation. Although understudied, recent studies position it as a critical player in carcinogenesis and neurodegenerative disorders, making it a potentially druggable node in cellular signaling networks. However, the phosphoregulatory networks and the upstream kinases governing OCIAD1 remain unknown. A large-scale literature mining and analysis of 177 phosphoproteomic datasets with differential expression of OCIAD1 was carried out to map its phosphoregulatory network. The predominant phosphosites were determined based on localization probability, detection frequency, and differential regulation. Multipronged computational approaches were employed to gather novel candidate kinases that may target OCIAD1 phosphosites. Co-differential phosphorylation analysis was conducted with other proteins, including interactors and candidate upstream kinases, to infer functional and regulatory associations. The sites S108 and S123 emerged as predominant, together accounting for 70% of OCIAD1 phosphorylation. Co-differential phosphorylation analysis revealed associations with proteins involved in the cell cycle, DNA repair, autophagy, mitophagy, endocytosis, and apoptosis. Novel candidate kinases for OCIAD1 phosphosites were identified; notably, SRMS and YES1 emerged as potential upstream regulators of Y199. Furthermore, the phosphosites in the candidate kinases of sites, including PLK1 (T210), CDK13 (S383, S397), PRKD2 (S200), CIT (S1343), and RPS6KA3 (T577), showed strong positive co-differential regulation with OCIAD1 predominant sites, supporting their potential involvement as upstream kinases. This study presents the first systematic map of the OCIAD1 phosphoregulatory network and provides candidate upstream kinases that may contribute to its phosphorylation, which warrant further experimental validation. The strong co-differential regulation of proteins involved in autophagy, mitophagy, endocytosis, and neurodegenerative pathways, as well as of kinases that orchestrate these processes, suggests that OCIAD1 phosphoregulatory network maybe involved in mitochondrial quality control and mitochondria-associated neurodegeneration, establishing a foundation for therapeutic investigations targeting OCIAD1 signaling.\n\nID: 42571660\nTitle: Ultra Broad Range Pressure Tunable CaZrO3:Ce3+ Luminescence for Multiparametric Manometry.\nAbstract: Optical manometry is essential in diamond anvil cell experiments, motivating pressure-sensitive phosphors that provide robust broadband readouts over a wide pressure range. Here we report a Ce3+-activated CaZrO3 perovskite phosphor with a low dopant level of about 0.40 atom % Ce quantified by EDS, and we evaluate its pressure-dependent luminescence response. Powder XRD and SEM-EDS confirm a single-phase CaZrO3 host and successful incorporation of the Ce activator. Temperature-dependent photoluminescence and lifetime measurements reveal that the material exhibits good thermal stability. Under compression up to 45 GPa, the broadband Ce3+ 5d-4f emission exhibits an almost linear redshift of the band centroid with d\u03bb/dP about 2.45 nm GPa-1 and a concurrent broadening of FWHM with dFWHM/dP about 1.15 nm GPa-1. In parallel, the CIE 1931 chromaticity coordinates derived from the full emission spectrum evolve regularly with pressure, enabling a continuous color change from blue to green and offering a convenient visual readout. High-pressure Raman spectra indicate a structural transition near 30 GPa, consistent with synchrotron XRD reports for CaZrO3, yet no discontinuity is observed in the pressure dependences of the luminescence parameters. First-principles calculations suggest that compression is mainly accommodated by ZrO6 octahedral tilting and anisotropic polyhedral compression, whereas the local Ce-O crystal-field environment evolves smoothly, accounting for the continuous optical response through the transition. These results establish CaZrO3:Ce3+ as a wide-range, multi-parameter optical manometer for high-pressure calibration at room temperature.\n\nID: 42571635\nTitle: Synthesis of \u03b2-Thiolated Amino Acids: Investigation Toward the Total Chemical Synthesis of Lasso Peptide Microcin J25.\nAbstract: Microcin J25 (MccJ25) is of special interest due to its \"lariat\" topology. The lasso architecture is thought to be responsible for its remarkable thermal stability (100\u00b0C for 30\u2009min incubation) and potency against Gram-negative bacteria (i.e., MBC of ~4.75\u2009\u00b5M against E. coli strain DH5\u03b1). This naturally occurring lasso peptide is formed via post-translational modifications (PTMs), including leader peptide removal and macrolactam cyclization between the N-terminus and 8-Glu side chain. Since the discovery of MccJ25 in 1992, synthetic endeavors toward the total chemical synthesis of MccJ25 have remained elusive. Herein, we investigated the chemical synthesis of MccJ25 utilizing \u03b2-thiol amino acids as the chemical tools to prestaple and rigidify the peptide backbone through disulfide linkages. Although the proposed chemical strategy failed to afford the desired lasso configuration, synthetic routes toward Fmoc-SPPS compatible, stereoselective \u03b2-thiol amino acids via thiazoline derivatives were developed. In addition, chemical/biochemical literature synthesis of MccJ25 and its analogs, as well as the synthesis of \u03b2-thiol amino acids, are summarized within.\n\nID: 42571634\nTitle: Enhanced Activity of Eugenol Pickering Emulsion Using Lactoferrin-Chlorogenic Acid Complex as a Green Stabilizer.\nAbstract: Exploiting natural and bioactive stabilizers to fabricate green emulsions has attracted increasing attention. In this work, lactoferrin (LF) was combined with chlorogenic acid (CGA) to construct the LF-CGA complex to prepare a eugenol (EG) Pickering emulsion (ELC/PE). The surface activity and binding mechanism of LF-CGA were explored. Additionally, the antioxidant, antibacterial, and anti-inflammatory capacities of ELC/PE were compared. The contact angle of LF-CGA approached 90\u00b0 (81.9\u00b0), indicating enhanced stability at the oil-water interface. The interaction between LF and CGA was primarily driven by static quenching and hydrogen bonding. The ELC/PE consisted of 1.5\u00a0wt% LF-CGA, with distilled water and EG as the aqueous and oil phases (15:1\u00a0v/v, aqueous/oil). The DPPH-, O2 -, and ABTS+ scavenging rates of ELC/PE were 86.3%, 75.3%, and 83.4%, respectively. The ELC/PE displayed superior antibacterial ability, along with inhibition rates of 99.0% and 99.5% against Candida albicans and Staphylococcus aureus, respectively. Additionally, the ELC/PE exhibited the most significant suppression of ear swelling (81.8%), confirming its anti-inflammatory ability. These values were the highest among all experimental groups. The LF-CGA complex acts as an emulsifier to enhance EG bioactivities. This novel complex holds great potential for expanding the practical applications of poorly soluble bioactive compounds.\n\nID: 42571624\nTitle: Boosting NIR Emissions and Thermal Resistance in Cr3+-Doped MgGa2O4 Semiconductor Microcrystals by Energy Transfer for Smart Detection.\nAbstract: High-radiant-intensity broadband near-infrared (NIR) emitters are highly desirable for nondestructive testing, night-vision imaging, and information encryption. However, the exploration of phosphors that possess both high luminous efficiency and outstanding thermal stability continues to pose significant difficulties. Among various NIR phosphor systems, Cr3+-doped MgGa2O4 (MGO:Cr3+) exhibits characteristic broadband emission. Herein, Bi3+ ions were incorporated as sensitizers into the MGO:Cr3+ phosphor system, resulting in substantial enhancements in photoluminescence (PL), mechanoluminescence (ML), and thermal stability. The Bi3+ co-doping enhanced the NIR PL intensity to 4.0 times and the ML output to 1.45 times those of the Cr3+ singly doped reference, indicating a pronounced sensitization effect and improved energy transfer efficiency. Furthermore, the emission-intensity retention at 423 K improved from 49.29 to 82.88%, confirming a significant enhancement in the thermal stability of the NIR emission. A broadband NIR phosphor-converted light-emitting diode (pc-LED) assembled by coupling the Bi3+, Cr3+-co-doped MGO with a blue LED further demonstrated the material's potential for nondestructive testing, night-vision imaging, and anti-counterfeiting.\n\nID: 42571621\nTitle: Synthesis of Some Oxime Derivatives as Novel Elastase Inhibitors: Molecular Dynamics Studies and Computational Insight.\nAbstract: Oximes and oxime ethers are important compounds in organic chemistry, both structurally and in terms of applications. The biological properties of oximes are directly related to the chemical properties of their functional groups, metal-binding capacities, and ability to interact with biological targets in a multifaceted way. This study presents the synthesis of 5-hydroxyimino 2a-b and 5-methoxyimino 2c derivatives from 5-oxo pentanoic acid methyl esters (1a-c) containing phenyl, p-chlorophenyl, and thiophenyl groups, elucidation of their structures through various spectroscopic analysis methods (IR, 1H NMR, 13C NMR, MS, and elemental analysis), and investigation of their elastase inhibition activities. In the elastase inhibition results, compounds were found to exhibit antielastase activity. Compound 2a, containing the p-chlorophenyl substituent, had the highest antielastase activity (IC50\u00a0=\u00a0426.68\u00a0\u00b1\u00a046.90\u00a0\u00b5M) and was found to have a lower IC50 value compared to the positive control, ursolic acid (486.19\u00a0\u00b1\u00a044.22\u00a0\u00b5M). Furthermore, molecular docking was used to predict binding affinities and found to be -5.8\u00a0kcal/mol for compound 2a and -6.8\u00a0kcal/mol for ursolic acid. Molecular dynamics simulations were conducted to evaluate the stability of protein-ligand interactions. These results suggest that compound 2a could be a potential elastase inhibitor candidate and scaffold for pharmaceutical or cosmetic applications.\n\nID: 42571617\nTitle: Bionic Flexible Wrinkled Strain Sensors With Water\u2011Accelerated Self-healing Capability for Underwater Detection and Motion Interaction.\nAbstract: Developing flexible sensors capable of long-term, high-sensitivity monitoring for flow fields and motion interactions is crucial for advancing unmanned underwater operations. However, flexible sensors always face challenges in achieving underwater superior self-healing performance and high sensitivity simultaneously. Here, inspired by human skin, we present a method combining force-driven wool spiral regulation with high-temperature to fabricate a flexible sensor with random wrinkled microstructures. Importantly, the sensor resumed usable output within just 8\u00a0min of incurring damage because dynamic borate ester bonds were applied to accelerate its underwater self-healing rate via hydrolysis-re esterification reactions. This bionic self-healing wrinkled flexible sensor achieves high underwater sensitivity, with average response and recovery time of only 124\u00a0ms and 112\u00a0ms, respectively, compared with most reported underwater flexible sensors with the same type of material of exceeding 200\u00a0ms. Notably, it maintains signal stability and functional continuity over 5,000 cycles following underwater self-healing. We further demonstrated its use in underwater vehicle model and human motion for confirming its underwater continuously outputting stable and sensitive signals. These findings advance the underwater self-healing flexible sensing units, with the potential to solve long-term and high-sensitivity condition monitoring towards underwater robotics, and water-resistant human-machine interfaces.\n\nID: 42571611\nTitle: Dual Oxygen Precursors Boosting the Ionic Conductivity of Glassy Electrolytes for All-Solid-State Sodium Batteries.\nAbstract: Amorphous halide-based solid electrolytes (SEs) are promising candidates for all-solid-state Na batteries (ASSNaBs) due to their structural flexibility and favorable mechanical properties. Among them, aluminum-based halide electrolytes are particularly attractive owing to their low cost and oxidative stability; however, previously reported systems typically exhibit limited room-temperature ionic conductivity (<1 mS cm-1). In this work, we report the synthesis of a transparent, viscoelastic Na-Al SE with the specific composition\u00a00.6NaClO-AlCl3-0.175SeO2, achieved through the strategic introduction of dual oxygen sources (NaClO and SeO2). This approach enables the modulation of charge carrier concentrations while simultaneously supplying sufficient oxygen. Furthermore, we introduce the concept of deoxygenation enthalpy to rationalize the selection of these dual oxygen sources among various oxide candidates. The resulting electrolyte achieves a high Na+ conductivity of 2.03 mS cm-1 at ambient temperatures, among the highest reported for Na-Al halide electrolytes. Molecular dynamics simulations confirm that segmental motion within the disordered framework actively facilitates Na+ transport, underpinning the observed viscoelastic behavior. When integrated into ASSNaB with uncoated NaNi0.4Fe0.2Mn0.4O2 cathode, the electrolyte enables stable long-term cycling and superior thermal compatibility, demonstrating practical applicability. This work establishes a new paradigm in rational precursor design for high-performance viscoelastic SEs.\n\nID: 42571610\nTitle: Antiphase Boundaries Regulate Phase Stability and Performance in DMA+-Assisted CsPbI3-Based Perovskites.\nAbstract: CsPbI3-based perovskites are promising absorbers for tandem solar cells owing to their optimal bandgap (\u223c1.7\u00a0eV). However, the phase transition from photoactive \u03b3-CsPbI3 to non-photoactive \u03b4-CsPbI3 remains a major obstacle and is strongly governed by microstructural defects formed during film growth. Among these, Ruddlesden-Popper antiphase boundaries (RP-APBs) are particularly prevalent and exhibit competing effects, relieving lattice strain while simultaneously facilitating moisture penetration, ion migration, and nonradiative recombination. Here, we systematically regulate RP-APB defects in \u03b3-phase CsPbI3 thin films and elucidate their decisive influence on both phase stability and optoelectronic performance. A compositional strategy based on PbI2 excess effectively reduces RP-APB density but induces edge-sharing [PbI6]4- motifs that nucleate the \u03b4 phase. In contrast, a dimethylammonium (DMA+)-assisted phase-engineering strategy forms \u03b2-(DMA,Cs)PbI3, which intrinsically suppresses RP-APB formation while preserving the photoactive perovskite framework. As a result, RP-APB-free \u03b2-phase films exhibit prolonged carrier lifetimes, strongly suppressed nonradiative recombination, and the lowest apparent trap densities, enabling a champion power conversion efficiency of 20.23% together with markedly enhanced operational, thermal, and ambient-air stability. This work demonstrates that regulating crystalline defects, exemplified by RP-APBs, plays a critical role in achieving both stable and efficient perovskite solar cells.\n\nID: 42571607\nTitle: Trions as Fundamental Species in Chemically Doped Polymer Semiconductors.\nAbstract: Doping is a cornerstone strategy for enhancing charge transport in semiconducting polymers, important for their application in, for example, semi-transparent electrode materials, thermoelectric devices, and antistatic coatings. Both chemical and electrochemical doping have, for this purpose, been the focus of extensive research resulting in considerable progress. However, the interactions between neutral excitons and doping-induced charges to form multi-particle states are largely unexplored in soft organic semiconductors, and their signatures remain poorly understood. Here, we demonstrate that coupling between excitons and polarons in doped polymers can lead to bound states such as trions (i.e., quasiparticles of an electron and two holes delocalized across three chromophores for p-doping), or bound exciton-hole pairs. Combining spectroscopic evidence with theoretical insights, we hypothesize that polymer architecture, dopant chemistry, and charge delocalization govern the formation and stability of these multi-particle states. More broadly, our findings reveal that trions and bound exciton-hole pairs-that is, three-body entities-are a key species in organic semiconductors that could open new pathways toward optoelectronic functionalities beyond conventional doping, including enhanced charge transport and quantum-coherent excitations.\n\nID: 42571606\nTitle: Gas-Shearing Microfluidic Fabrication of Alginate/Chitosan Hydrogel Microreactors for Genipin-Mediated Dual-Mode Lipase Immobilization.\nAbstract: Enzyme immobilization is an effective strategy to improve catalyst recovery and operational stability, but conventional approaches are often limited by diffusion resistance, steric hindrance, and insufficient control over the enzyme microenvironment. Hydrogel-based materials are attractive supports because their hydrated, tunable, and porous networks help preserve enzyme conformation while improving substrate diffusion and mass transfer. Here, a gas-shearing microfluidic strategy was developed to fabricate alginate/chitosan hydrogel microreactors for dual-mode lipase immobilization through entrapment and genipin-mediated covalent binding. By tuning gas-liquid shear, microspheres with controllable and narrow size distribution were generated without surfactants or UV-initiated polymerization. Importantly, genipin was introduced as a mild and biocompatible cross-linker to reinforce the alginate/chitosan network and create a stable interfacial microenvironment for enzyme immobilization. Compared with conventional cross-linkers, the milder and more controllable reactivity of genipin is advantageous in preserving enzyme conformation and catalytic performance. The resulting microreactors exhibited enhanced catalytic activity, improved storage stability, and good reusability. After five consecutive cycles, the entrapped and covalently immobilized systems retained 70% and 81% of their initial activity, respectively. These results demonstrate that gas-shearing microfluidics combined with genipin-mediated network reinforcement provides a robust and biocompatible platform for constructing hydrogel-based enzymatic microreactors with improved catalytic performance and operational durability.\n\nID: 42571596\nTitle: Roles of polysaccharide charge and viscosity in soy protein-polysaccharide stabilized high internal phase emulsions for plant-based patties.\nAbstract: Soy protein isolate (SPI)-polysaccharide-stabilized high internal phase emulsions (HIPEs) are promising fat alternatives for meat analogs. However, the distinct contributions of polysaccharide charge and viscosity to emulsion formation, stabilization and meat analog quality remain unclear. This study systematically investigated five polysaccharides with different charges and viscosities, namely cationic chitosan (CS), neutral locust bean gum (LBG) and guar gum (GG), and anionic xanthan gum (XG) and high methoxyl pectin (HP), in modulating SPI structure, HIPE performance, and plant-based patty quality. Results showed that polysaccharide charge dominated SPI-polysaccharide interactions and dictated SPI conformational remodeling. Neutral polysaccharides interacted with SPI through hydrogen bonding/hydrophobic interactions, significantly increasing the \u03b2-sheet content (GG: from 35.91% to 43.23%), and achieving the smallest initial droplet size through a high interfacial adsorption rate (GG: 6.81\u202f\u03bcm). During emulsion stabilization and flavor retention, viscosity was the predominant factor. High-viscosity XG and GG excelled in inhibiting droplet aggregation, reducing gravitational separation, and maximizing volatile flavor retention under both heating and storage. At the application stage, viscosity predominantly influenced the hardness of patties. This study reveals the division of labor between polysaccharide charge and viscosity across different performance dimensions of HIPEs, guiding polysaccharide selection for tailoring HIPEs in meat analogs.\n\nID: 42571507\nTitle: A novel strategy for controlled release of sialic acid based on W1/O/W2 emulsion microencapsulation for gut microbiota modulation.\nAbstract: Sialic acid (Neu5Ac) possesses a wide range of bioactivities; however, its instability under acidic conditions prevents it from effectively reaching the intestine. This underscores the urgent need to develop a stable delivery system capable of protecting Neu5Ac from gastric degradation and achieving its controlled release in the intestine. To enhance the stability and achieve controlled release, Neu5Ac was encapsulated within water-in-oil-in-water (W1/O/W2) emulsion-based microcapsules in this work. S2 emulsions featured a \"dual-chamber, tri-phase\" structure, comprising a Neu5Ac-chitosan fluid gel (inner aqueous phase), maize oil (oil phase), and an external aqueous phase of 13% sodium starch octenyl succinate, 5% \u03b2-cyclodextrin, 1.5% sodium caseinate, and 0.5% carboxymethyl cellulose. Microstructural analyses confirmed spherical morphology with core-shell architecture and bimodal droplet distribution (1-10\u202f\u03bcm). In addition, S2 emulsions exhibited an encapsulation efficiency (EE) of 92.44%, a zeta potential of -60.80\u202fmV, a Sauter mean diameter (d3,2) of 1.337\u202f\u03bcm, shear-thinning behavior and weak gel network stability. S2 emulsions were spray-dried to obtain S2 microcapsules. S2 microcapsules exhibited an EE of 89.43% and a d3,2 of 3.839\u202f\u03bcm, while FT-IR and XRD verified physical encapsulation without covalent bonding. In vitro digestion, S2 microcapsules exhibited controlled release behavior during simulated intestinal digestion, with a Neu5Ac release rate of 85.61% after 120\u202fmin. In mice, microencapsulated Neu5Ac increased the relative abundance of Akkermansia, Lactobacillus, and Bifidobacterium. This system demonstrates promising potential for the co-delivery and controlled release of Neu5Ac, and shows great promise for expanding its applications in the food industry.\n\nID: 42571477\nTitle: Clustering of non-invasive biomarkers to distinguish phenotype-related response differences in women with PCOS after the 16-week Nordic interval training intervention: A prospective cohort study.\nAbstract: Polycystic ovary syndrome (PCOS) is associated with metabolic and reproductive abnormalities. Response variability due to exercise may reflect underlying biological heterogeneity in PCOS phenotypes. We explored changes in non-invasive PCOS biomarkers following a 16-week Interval Nordic Walking (INW) to identify phenotype-related response differences. A total of 7500 women's data were obtained from the Yazd Reproductive Sciences and Amir al M\u00f3menin Hospital (2019-2024). PCOS was diagnosed according to the Rotterdam criteria. XGBoost feature selection was implemented to choose 17 key predictors. Multiple ML classifiers were evaluated, and model interpretability was achieved using SHAP values. 80 women with different PCOS phenotypes completed a 16-week INW intervention. PCA was applied to reduce the features to 75% variance. Then clustering algorithms (K-means, GMM, Hierarchical, Spectral, DBSCAN) were evaluated using Silhouette scores, Calinski-Harabasz indices, and bootstrap resampling (Jaccard index). XGBoost and SHAP analysis confirmed AMH, FSH, and Anti-TPO as the most influential predictors of PCOS, while metabolic indices like HbA1c, BMI, and lipid profiles exhibited moderate but clinically relevant effects. The spectral model provided better separation among evaluated algorithms; however, overall cluster separation remained modest. It suggested two exploratory data-driven response patterns, termed high-response (more frequently observed phenotypes one and two), which demonstrated greater observed reductions in testosterone and DHEA-s along with improvements in HDL and total cholesterol following the intervention. Low-response (more frequently observed phenotypes three and four) showed relatively minimal response to INW. Based on mean Jaccard index\u202f=\u202f0.45, cluster stability was moderate. Our study suggests the heterogeneous phenotypic response pattern of PCOS following a 16-week INW intervention and supports further investigation of nonpharmacological strategies for PCOS.\n\nID: 42571472\nTitle: Consistency evaluation protocol: A reproducible framework for assessing large language model output repeatability.\nAbstract: The stochastic behaviour of Large Language Models (LLMs) generates varied responses when prompted with the same inputs and parameters. Recent researchers have explored various techniques to understand this behaviour of LLMs, including uncertainty measures, semantic consistency, robustness, and prompt sensitivity. However, the research lacks a reproducible methodology that combines semantic and structural parameters. Thus, the proposed consistency evaluation protocol focuses on evaluating the consistency of LLM responses through repeated prompting, extracting relevant features, and analysing structural and semantic stability through consistency scores. The framework was evaluated using Mistral-7B-Instruct-v0.2 on a set of 20 input texts. For each input text, five independent responses were generated. For each of the generated responses, semantic consistency is determined through embedding-based text representations. In addition, the structural variation is studied through fluctuations in sentence length, word usage, and lexical diversity. Lastly, these measurements are combined to form the Composite Consistency Score (CCS). Further, the validation tests are performed, containing temperature sensitivity, prompt sensitivity, and metric validations reflecting reliable and reproducible consistency evaluations.\n\nID: 42571444\nTitle: Wearable bioelectronics enabled by conductive hydrogels: From materials innovation to clinical translation.\nAbstract: The rapid evolution of wearable bioelectronics is transforming healthcare toward continuous, non-invasive monitoring and personalized intervention. Central to this progress is the development of materials that integrate mechanical compliance, reliable signal transduction, and long-term biocompatibility. Conductive hydrogels have emerged as a promising platform, combining tissue-like mechanics with tunable ionic/electronic conductivity to enable stable and conformal biointerfaces. This Review examines how materials design and nanocomposite engineering govern charge transport, mechanical robustness, and dynamic responsiveness, and how these structure-property relationships translate into device performance. Representative applications span metabolic, cardiovascular, and neurological monitoring, as well as wound care, sleep analysis, and biomarker detection. We further identify key challenges for clinical translation, including long-term stability, multimodal integration, and data reliability, and outline future directions toward integrated, intelligent, and closed-loop bioelectronic systems.\n\nID: 42571416\nTitle: EEG microstates and dynamic functional connectivity reveal stage-specific brain networks in subjective tinnitus.\nAbstract: Tinnitus with normal hearing suggests central mechanisms, yet stage-specific brain network dynamics remain unclear. This study investigated stage-specific brain network patterns in normal-hearing tinnitus patients using electroencephalography (EEG) microstate and dynamic functional network (DFN) analyses. Resting-state EEG was recorded from 45 participants (15 acute tinnitus, <6 months; 15 chronic tinnitus, \u22656 months; and 15 healthy controls). Results showed that acute tinnitus involved enhanced salience network engagement and reduced central executive network participation, with transitions skewed toward salience processing. Chronic tinnitus exhibited normalized transitions but increased global explained variance, indicating greater network stability. DFN analysis revealed elevated \u03b3-band efficiency in the executive network during acute tinnitus, while chronic tinnitus showed increased low-frequency (\u03b4/\u03b2) efficiency in executive and auditory networks. These findings demonstrate distinct neurophysiological profiles across tinnitus stages-acute salience-executive imbalance with aberrant high-frequency synchrony versus chronic compensatory rebalancing through low-frequency adaptation-providing a framework for stage-specific biomarker identification.\n\nID: 42571415\nTitle: Hyaluronic acid-engineered copper sulfide nanoparticles as immunomodulatory metal sulfide photothermal agents for macrophage-assisted osteosarcoma therapy.\nAbstract: Metal sulfide nanomaterials have emerged as promising photothermal agents for cancer therapy owing to their strong near-infrared absorption, favorable biocompatibility, and tunable surface chemistry. However, insufficient tumor accumulation and limited immunological activation remain major obstacles restricting their therapeutic efficacy in solid tumors. Herein, we report a macrophage-assisted delivery strategy based on hyaluronic acid-engineered copper sulfide nanoparticles (HA@CuS NPs) for enhanced photothermal-immunotherapy against osteosarcoma. In this system, adoptively transferred RAW264.7 macrophages were intravenously administered to increase macrophage enrichment within the osteosarcoma microenvironment, while HA@CuS NPs were rationally designed to target both tumor cells and tumor-associated macrophages through HA-mediated cellular recognition. The HA-coated CuS nanoparticles displayed good colloidal stability, efficient near-infrared photothermal conversion, and enhanced cellular uptake by osteosarcoma cells and macrophages. Importantly, macrophages acted as cellular reservoirs for CuS nanoparticles, promoting tumor accumulation and improving intratumoral photothermal distribution. Under 808-nm laser irradiation, the combined macrophage/HA@CuS treatment produced stronger tumor heating and more effective osteosarcoma ablation than HA@CuS nanoparticles alone. Beyond direct photothermal killing, HA@CuS nanoparticles also remodeled the tumor immune microenvironment by promoting M1-like polarization of tumor-associated macrophages, increasing IL-12p40 secretion, reducing IL-10 levels, and enhancing cytotoxic T lymphocyte infiltration. These immune-regulatory effects further amplified the antitumor response induced by photothermal therapy. Collectively, this study demonstrates that HA-engineered copper sulfide nanoparticles can function not only as metal sulfide photothermal agents but also as immunomodulatory nanomaterials. The integration of macrophage-assisted tumor delivery with CuS-based photothermal therapy provides a promising strategy for improving the therapeutic efficacy of metal-based nanomedicine against osteosarcoma.\n\nID: 42571396\nTitle: Dual-modal antioxidant and epigenetic synergy attenuates the self-perpetuating senescence cycle in osteoarthritis.\nAbstract: Osteoarthritis (OA) arises from chondrocyte senescence driven by intertwined oxidative stress and abnormal m6A methylation, with few treatments targeting both pathological pathways. Lycopene, an antioxidant, is limited by poor bioavailability, whereas Wilms tumor 1-associating protein (WTAP), a core m6A methyltransferase, has no specific inhibitors. Herein, we fabricated cartilage-targeted HPcLW nanoparticles (\u223c250\u202fnm) via electrostatic self-assembly of human serum albumin (HSA) and poly-L-lysine (PLL) with collagen II-binding peptide, co-loaded with lycopene and WTAP siRNA. The targeting modification extended joint fluorescence retention to 10 days after intra-articular injection with good serum stability and biosafety. In aged mice and medial meniscus (DMM)-induced OA mouse models, intra-articular HPcLW attenuated cartilage degeneration, restored COL2 expression, and suppressed MMP13 levels. Mechanistically, WTAP siRNA suppressed m6A modification to downregulate PAI-1 expression, while lycopene scavenged ROS and protected siRNA integrity, cooperatively disrupting the WTAP/PAI-1 axis and alleviating mitochondrial dysfunction. By integrating antioxidant and epigenetic strategies, HPcLW counteracts the senescence loop, establishing the WTAP/PAI-1 axis as a therapeutic target and highlighting co-delivery nanomedicine for age-related joint diseases.\n\nID: 42571381\nTitle: Five-year skeletal and dental stability following bilateral sagittal split osteotomy for mandibular advancement in Class 2 malocclusion.\nAbstract: Bilateral sagittal split osteotomy (BSSO) is widely used for mandibular advancement in patients with skeletal Class 2 malocclusion; however, long-term postoperative stability remains an important clinical concern. To evaluate long-term skeletal, dentoalveolar, and soft tissue stability following mandibular advancement with BSSO and rigid fixation. A retrospective cohort study was conducted in 32 patients undergoing mandibular advancement with BSSO and rigid fixation. Cephalometric measurements were obtained at four time points: preoperative, immediate postoperative, 12 months, and long-term follow-up (>3 years). Changes were analyzed using the Wilcoxon signed-rank test. The mean mandibular advancement was 5.42\u202f\u00b1\u202f1.71\u202fmm. Immediately after surgery, significant skeletal correction was achieved, with increased SNB and decreased ANB (both p\u202f<\u202f0.001), accompanied by significant improvements in occlusal and soft tissue profile measurements. Most skeletal and occlusal parameters remained stable during the first postoperative year and throughout long-term follow-up, with no statistically significant changes observed between one year and the final evaluation. Soft tissue remodeling continued during follow-up, whereas overall skeletal and dental stability was maintained. Bilateral sagittal split osteotomy with rigid fixation effectively corrected skeletal Class 2 malocclusion and demonstrated favorable long-term skeletal, dental, and soft tissue stability.\n\nID: 42571373\nTitle: Correction of Supernumerary Tooth-Associated Anterior Crossbite in Mixed Dentition Using a 2\u2009\u00d7\u20094 Appliance.\nAbstract: Anterior crossbite is a common tooth alignment discrepancy seen among the paediatric population especially during the mixed dentition stage. There are many causes of anterior crossbite, and the presence of supernumerary tooth/teeth is one of them. Early interceptive intervention is essential to avoid the need for more complex orthodontic treatment later. This case report describes the management of a 10-year-old child who presented with anterior crossbite involving Teeth 21 and 31, leading to gingival recession of Tooth 31. The crossbite malocclusion was associated with a supernumerary tooth in the upper incisor region. Extraction of the supernumerary tooth was performed, and correction of the anterior crossbite was commenced with a 2 \u00d7 4 appliance. Adequate stability with a positive overjet was observed at the 6-month review. The 2 \u00d7 4 orthodontic appliance may be considered a treatment option for correcting anterior crossbite in patients with poor compliance with removable appliance therapy.\n\nID: 42571360\nTitle: A UAV-based semi-supervised segmentation framework for pine wilt disease via vegetation Index-RGB synergy.\nAbstract: Pine wilt disease (PWD), caused by the pine wood nematode (Bursaphelenchus xylophilus), continues to threaten forest ecological security. Unmanned aerial vehicle (UAV) remote sensing makes large-scale screening feasible, but accurate canopy segmentation remains difficult in practice. The main obstacles are threefold: (i) canopy appearance changes noticeably from early to late infection stages, which can cause model representations to drift toward later-stage symptoms and weaken subtle early-stage cues; (ii) dense pixel-wise annotation is costly, making semi-supervised learning dependent on imperfect pseudo-labels; and (iii) forest backgrounds are cluttered and often visually similar to diseased regions, limiting the discriminative ability of RGB appearance alone. To address these three practical difficulties, we build a standardized UAV canopy dataset for PWD and develop a lightweight multimodal segmentation framework. The method combines three components. First, Nested-Tempo Memory Consolidation (NTMC) is designed as a stage-aware extension of EMA-based teacher-student learning. It maintains nested fast/medium/slow temporal trajectories to retain stage-specific knowledge while improving cross-stage stability during Early-Middle-Late sequential training. Second, Drift-Compensated Consistency Regularization (DCCR) integrates reliability calibration into semi-supervised consistency learning, so that unlabeled samples contribute training signals mainly when they are sufficiently reliable, reducing error accumulation from noisy pseudo-supervision. Third, Vegetation-index-conditioned Cross-Modal Attention (VCCA) uses vegetation indices-Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI)-as physiological cues to modulate visual features, thereby reducing the dependence on RGB appearance and improving feature discrimination under texture-similar forest backgrounds. Experiments on one in-house dataset and three external datasets show consistent improvements in mean intersection over union (mIoU), F1-score, and Matthews correlation coefficient (MCC). With all components enabled, the framework improves mIoU from 0.6015 to 0.6829 over the baseline and produces cleaner disease boundaries with fewer background false alarms, demonstrating its potential for practical UAV-based forest disease monitoring.\n\nID: 42571336\nTitle: Interfacial and colloidal drivers of wine drying astringency: the role of wine-saliva aggregates.\nAbstract: Astringency in red wine is associated with lubrication changes driven by tannin-saliva interactions, yet the physicochemical basis of astringency subqualities remains unclear. Focusing on drying, a key quality-related subquality, we examined whether wine-saliva aggregates can contribute to lubrication stability rather than only increasing friction. Red wines spanning non-drying to highly drying profiles were mixed 1:1 with unstimulated human saliva. Film thickness and friction were measured under controlled, oral-inspired sliding conditions, and mixtures were centrifuged to obtain soluble (supernatant) and insoluble (pellet) fractions characterized for colloidal stability, interfacial wetting, turbidity, viscosity, and macromolecular composition. Lower drying was associated with thicker films and lower friction, with more stable, entrainable supernatants showing more negative zeta potential, smaller colloids, higher suspended turbidity, and greater polysaccharide support. Overall, the results support a supernatant-centric view in which aggregate functionality and morphology relate to drying subquality, suggesting routes to soften mouthfeel without necessarily reducing phenolics.\n\nID: 42571327\nTitle: Isolation, characterization, and alginate hydrogel delivery of a Klebsiella aerogenes bacteriophage and its impact on biofilm degradation.\nAbstract: Multidrug-resistant Klebsiella aerogenes poses a significant clinical challenge due to its antimicrobial resistance and biofilm-forming capacity in chronic wounds and device-associated infections. Bacteriophage therapy offers a promising alternative to conventional antibiotics, though effective delivery systems remain critical for clinical translation. This study reports the isolation, genomic characterization, and alginate hydrogel-based formulation of a lytic bacteriophage, KA_SGEB_01, targeting multidrug-resistant K. aerogenes. The phage was isolated from hospital sewage using multidrug-resistant K. aerogenes as a host. Comprehensive characterizations included plaque morphology and host range determination, multiplicity of infection (MOI) optimization, one-step growth kinetics, antibiofilm activity assays, and environmental stability testing. Complete genome sequencing and annotation were performed. Phage-loaded alginate hydrogels were developed and evaluated for release kinetics, long-term viability, and antibiofilm efficacy. KA_SGEB_01 produced clear plaques (1 \u00b1 0.1 mm) with halos indicative of depolymerase activity and exhibited strict host specificity. The optimal MOI was 0.01 with a 15-minute latent period and the phage remained stable between -20 \u00b0C and 50 \u00b0C; and across a pH range 6-9. Biofilm assays demonstrated around 60% Crystal-Violet-stained biomass reduction as well as significant biofilm disruption visualized by Scanning Electron Microscopy. Whole-genome sequencing revealed a 175,095 bp double-stranded DNA genome encoding 289 predicted coding sequences, classified within the family Straboviridae, genus Slopekvirus, and lacking any virulence or AMR genes. Encapsulation in alginate hydrogels preserved viability (>10\u2079 PFU/mL) for 14 days and enabled sustained release (\u223c 67% at 72 h), resulting in significant biofilm biomass inhibition. Collectively, KA_SGEB_01-loaded alginate hydrogels represent a promising platform for treating multidrug-resistant K. aerogenes in wound and device-associated infections caused by the bacterium.\n\nID: 42571237\nTitle: JS-Drift: A reproducible Jensen-Shannon divergence procedure for drift-aware client weighting in federated learning.\nAbstract: Federated learning lets institutions train a shared model without exchanging raw data, but standard aggregation (FedAvg) assumes client data distributions are stationary. In practice they drift over time, and aggregation that ignores this lets unstable clients degrade the global model. This article describes JS-Drift, a reproducible, model-agnostic procedure that quantifies per-client temporal drift using Jensen-Shannon (JS) divergence between a client's label distribution in consecutive communication rounds, converts that divergence into a stability weight via a single sensitivity parameter \u03b3, and folds the weight into the aggregation step. The procedure requires no architectural changes, adds negligible overhead, and drops into any FedAvg-style training loop. We give the full algorithm, exact computation steps, parameter-selection guidance, and an open implementation, and we validate that the procedure behaves as intended on three structurally different tabular-classification settings.\u2022Computes a per-client, per-round drift coefficient from JS divergence between consecutive local label distributions; only a small class-proportion summary is shared, so raw data never leave the client.\u2022Maps the drift coefficient to an aggregation weight through one interpretable parameter \u03b3, down-weighting clients with high distributional shift.\u2022Is model-agnostic and integrates into any FedAvg-style round in a few lines of code; a public repository reproduces every step.\n\nID: 42571215\nTitle: Comparison of En Masse Retraction and Two-Step Retraction Mechanics in Class I Bimaxillary Protrusion: A Retrospective Comparative Study.\nAbstract: Bimaxillary protrusion is commonly treated using extraction-based orthodontic therapy, followed by anterior tooth retraction. En masse retraction and two-step retraction are widely used space-closure mechanics; however, differences in treatment efficiency, anchorage preservation, and arch dimensional changes remain. This study aimed to compare the outcomes of en masse retraction and two-step retraction mechanics in patients with Class I bimaxillary protrusion undergoing extraction-based orthodontic treatment. This retrospective comparative study evaluated the completed orthodontic records of 100 patients with Class I bimaxillary protrusion who were treated between 2016 and 2021. The patients were classified into two groups: en masse retraction (n = 50) and two-step retraction (n = 50). Measurements were obtained from the pretreatment and post-treatment study models and treatment records. The variables assessed were maxillary incisor retraction, anchorage loss, treatment duration, retraction rate, extraction space closure efficiency, residual extraction space, and transverse arch dimensional changes. Data were analyzed using an independent samples t-test, a chi-square test, and a Mann-Whitney U test. Statistical significance was set at p < 0.05. Both treatment modalities achieved comparable maxillary incisor (6.84 \u00b1 1.12 mm vs. 6.52 \u00b1 1.08 mm; p = 0.129). The en masse retraction group demonstrated significantly greater anchorage loss, with a first molar mesial drift of 2.18 \u00b1 0.76 mm compared with 1.43 \u00b1 0.61 mm in the two-step retraction group (p < 0.001). Space closure duration was significantly shorter in the en masse group (8.6 \u00b1 1.8 months) than in the two-step group (11.4 \u00b1 2.3 months) (p < 0.001). Extraction space closure efficiency was higher in the en masse group (96.90 \u00b1 2.80%) than in the two-step group (95.40 \u00b1 3.20%) (p = 0.011). Significant reductions in intercanine, intermolar, and interpremolar widths were observed in the en masse group compared with the two-step group (p < 0.001). Both retraction mechanics were effective in achieving anterior tooth movement. En masse retraction provided faster space closure and greater treatment efficiency but was associated with increased anchorage loss and greater transverse arch constriction. Two-step retraction demonstrated superior anchorage preservation and transverse dimension stability.\n\nID: 42571201\nTitle: An Assessment of Implant Stability and Bite Force Following Early and Delayed Dental Implant Placement.\nAbstract: Introduction The timing of dental implant placement following tooth extraction is an important clinical consideration because it may influence osseointegration and functional rehabilitation. Although both early and delayed implant placement protocols are widely used, evidence regarding their effects on implant stability and masticatory function is limited. This study aimed to compare early and delayed dental implant placements in terms of implant stability and bite force. Materials and methods This prospective observational study was conducted at the Department of Prosthodontics, K. M. Shah Dental College and Hospital, Sumandeep Vidyapeeth (Deemed to be University), Vadodara, Gujarat, India. Sixty patients were categorized into two groups of 30 participants in each group. The early implant group received implants four to eight weeks after tooth extraction, whereas the delayed implant group underwent implant placement after a minimum healing period of six months. Implant stability was assessed using resonance frequency analysis (RFA) and expressed as implant stability quotient (ISQ) values. Functional rehabilitation was evaluated by measuring the bite force using a digital occlusal force analyzer. Assessments were performed at baseline and six months after prosthetic loading. Statistical analyses were conducted using paired and independent t-tests, with statistical significance set at p < 0.05. Results Both groups demonstrated significant improvements in implant stability and bite force over the six-month follow-up period (p = 0.001). In the early implant group, the mean ISQ values increased from 62.4 \u00b1 4.8 to 74.6 \u00b1 3.9, whereas the delayed implant group showed an increase from 58.7 \u00b1 5.2 to 71.2 \u00b1 4.6. The bite force increased from 128.4 \u00b1 22.6 N to 218.3 \u00b1 31.4 N in the early implant group and from 134.7 \u00b1 25.1 N to 204.6 \u00b1 28.9 N in the delayed implant group. The early implant group demonstrated significantly higher implant stability at baseline and six months (p < 0.05). Although the bite force values at individual time points were comparable between the groups, the increase in bite force over time was significantly greater in the early implant group (p = 0.006). Conclusions Both early and delayed implant placement protocols achieved successful osseointegration and functional rehabilitation in the present study. However, early implant placement demonstrated superior implant stability and greater improvement in bite force, suggesting that it may provide favorable clinical outcomes when appropriate case selection and treatment planning are performed.\n\nID: 42571191\nTitle: Material Needs Security and Food Security Among Lebanese Adults with Type 2 Diabetes: A Cross-Sectional Study.\nAbstract: Type 2 diabetes (T2DM) is a growing public health concern, particularly in the Middle East and North Africa (MENA) region, where prevalence rates continue to rise. Social determinants of health, including material needs security and food security, play a critical role in diabetes management, yet their interrelated effects remain underexplored. This study aims to examine the relationship between material needs security and food security among Lebanese adults with T2DM of low socioeconomic status. A cross-sectional study was conducted on 299 Lebanese adults with T2DM recruited from three primary health care centers. Participants completed validated questionnaires assessing sociodemographic factors and food security. Material needs security score was computed based on ownership and access for certain house utilities, as well as car ownership. Unadjusted and adjusted logistic regression models were conducted to evaluate associations between material needs security and food security. Higher material needs security was significantly associated with food security in both the unadjusted and adjusted regression models (odds ratio = 1.26, 95% confidence interval: 1.06-1.49, p = 0.007). Food and material needs insecurities were more prevalent among females and individuals with lower income, lower education, and lack of health insurance. This study highlights the strong association between material needs security and food security in Lebanese adults with T2DM, emphasizing the importance of addressing social determinants in diabetes management. Policies targeting financial stability, food security interventions, and access to health care are essential to improving health outcomes in vulnerable populations.\n\nID: 42571165\nTitle: A Comprehensive In-Silico Pipeline for the Discovery of Non-toxic, Stable Antimicrobial Peptides From Databases for Targeting Multi-Drug Resistant K. pneumoniae.\nAbstract: The rapid emergence of multidrug-resistant Klebsiella pneumoniae has significantly reduced the effectiveness of conventional antibiotics, highlighting the need for alternative therapeutic strategies. This study employed a comprehensive in silico pipeline to identify antimicrobial peptides (AMPs) targeting the essential DNA replication initiator protein DnaA. A total of 28,361 peptide sequences were collected from publicly available AMP databases and sequentially filtered based on peptide length, net charge, GRAVY score, instability index, antimicrobial activity, toxicity, hemolytic potential, aggregation propensity, sequence similarity and favorable amphipathic properties. Four peptides satisfied all selection criteria and were subjected to structural prediction, membrane-binding analysis, protein-DNA docking, protein-peptide docking, and Normal Mode Analysis. Protein-DNA docking identified the functional DNA-binding residues of DnaA, while peptide docking demonstrated that all four peptides interacted within this region. Peptide 3 exhibited the strongest predicted interaction, with a binding energy of -61.8\u00b15.1, a buried surface area of 1151.7\u00b130.8 \u00c52, and seven hydrogen bonds with key DnaA residues. Normal Mode Analysis further supported the structural stability of the peptide-protein complexes. These findings identify four promising AMP candidates targeting DnaA and provide a computational framework for peptide prioritization against multidrug-resistant K. pneumoniae. However, the proposed interactions remain computational predictions and require experimental validation.\n\nID: 42571132\nTitle: Pre-fieldwork core competencies for mental health occupational therapy students in Taiwan under conditions of volatility, uncertainty, complexity and ambiguity: A Delphi method.\nAbstract: In mental health occupational therapy (MHOT) fieldwork, the volatility, uncertainty, complexity and ambiguity (VUCA) environment poses challenges for students. The present study, conducted in Taiwan, aimed to identify pre-fieldwork core competencies essential for preparing occupational therapy undergraduates for mental health fieldwork, with a focus on professional readiness and resilience. A two-round Delphi survey was conducted with MHOT fieldwork instructors across Taiwan. Round 1 included 14 experts (10 completed) and generated preliminary items through qualitative analysis. Round 2 involved 20 experts (16 completed) who rated item appropriateness and agreement. Consensus was evaluated using descriptive statistics and predefined thresholds. Expert consensus confirmed 15 pre-fieldwork core competencies; each meeting established subjective criteria (median, interquartile range, standard deviation). Content validity ratios exceeded 0.49, averaging 0.76. The Percentage of Positive Ratings ranged from 52.94% to 94.12%, averaging 82.75%, surpassing the 70% threshold. Kendall's W showed moderate agreement for definition appropriateness (0.494, p\u2009<\u20090.000) and overall agreement (0.34, p\u2009<\u20090.000). Metrics for convergence, consensus and stability (0.34-0.85) confirmed strong expert alignment. The framework comprises 11 core and 4 adaptive competencies, organised into 5 domains, and provides a practice-oriented blueprint for early clinical preparation in VUCA-challenged mental health settings.\n\nID: 42571125\nTitle: Stability of Stochastically Forced Solitons in the Korteweg-de Vries Equation.\nAbstract: We study the stability and dynamics of solitons in the Korteweg-de Vries (KdV) equation in the presence of noise and deterministic forcing. The noise is space-dependent and statistically translation-invariant. We show that, for small forcing, solitons remain close to the family of traveling waves in a weighted Sobolev norm, with high probability. We study the effective dynamics of the soliton amplitude and position via their variational phase, for which we derive explicit modulation equations. The stability result holds on a time scale where the deterministic forcing induces significant amplitude modulation.\n\nID: 42571111\nTitle: Focalplasty for Resurfacing of Focal Articular Lesions of the Medial Femoral Condyle.\nAbstract: Focal osteochondral defects of the knee are difficult to manage, as untreated lesions may progress to early osteoarthritis. The OvertureTi Knee Resurfacing System is designed to treat focal defects while preserving native bone, cartilage, and soft tissue. Focalplasty is indicated in patients with compartmentalized cartilage lesions, preserved ligamentous stability, and meniscal integrity or repairable tears. Appropriate alignment, joint space preservation, and minimal osteophyte formation are required. The procedure began with arthroscopic repair of the medial meniscus root using a transtibial pull-out technique. Following this, an open approach was performed to expose the medial femoral condyle. The chondral defect was sized, and appropriate instrumentation was used to prepare the site. Cartilage scoring and sequential reaming were performed to achieve the desired depth and contour. Trial components were confirmed to fit and position, after which peg holes were drilled and filled with bone cement. Finally, the oblong OvertureTi femoral implant was seated flush with the surrounding cartilage surface, and standard wound closure was completed. At 2 weeks, radiographs confirmed proper implant positioning. Long-term outcomes of the Overture prosthesis are not yet available. However, studies on similar implants, such as the HemiCAP, have reported improved function and survivorship at mid- to long-term follow-up. The Overture prosthesis offers advantages over arthroplasty and biologic resurfacing, including lower cost, off-the-shelf availability, preservation of native tissues, and bone conservation for future arthroplasty. Larger prospective studies are required to determine its long-term clinical efficacy. The author(s) attests that consent has been obtained from any patient(s) appearing in this publication.

Iridium oxide, the preferred anode catalyst in PEMEL, offers exceptional stability but is produced only as a by-product of platinum mining, with annual output around 7.5 tons. This study estimates future iridium demand for PEMEL under various global deployment scenarios and technological advances. Results show that meeting net zero targets will require both significant improvements in catalyst efficiency and access to roughly 30% of global iridium production annually. Supply shortages could arise as early as 2030, earlier than previously anticipated. The analysis also reveals that long-term iridium needs beyond 2040 are significantly underestimated. These findings underscore the urgent need for innovation in material efficiency and recycling, and the importance of integrating resource constraints into energy policy and technology planning to ensure a sustainable hydrogen transition.

A fine-grained climatic resolution is indispensable to anticipate species-specific habitat redistributions for effective conservation planning. Focusing on 20 giant panda forage bamboo (GPFB) species across 5 genera that constitute the bulk of the giant panda's (Ailuropoda melanoleuca) diet, we developed a \"species-distribution modelling based on climate-delta downscaling\" framework to project potential geographic shifts at a 30\u2009m resolution across the 21st century under SSP1-2.6, SSP2-4.5, and SSP5-8.5 scenarios. We found three primary results: (1) while the total climatically suitable area for GPFB expands under future scenarios, localized species richness within these habitats declines. (2) A mid-elevation bamboo buffer zone (3000-4500\u2009m) emerges as a critical thermal sanctuary where 7 out of 20 species expand under an unlimited dispersal assumption. However, incorporating a realistic biological dispersal constraint (10\u2009m/year) severely truncates this elevational advantage, precipitating an overall habitat contraction for 11 species and reducing accessible refugia to merely 44%-65% of their theoretical potential. At localized scales, range shifts exhibit non-monotonic trajectories and multidirectional movements rather than uniform upslope or northward migrations. (3) Integrating baseline and 12 future projections, we delineated stable macroclimate refugia governed by steep topographies, high hydrological availability, long-term annual precipitation stability, and distinct seasonal environmental variations. 78.6% to 89.2% of the bamboo climate refuges overlap with the current (in 2025) forest distribution. Alarmingly, only 38.46%-44.11% of these crucial refugia fall within the current boundaries of the Giant Panda National Park, leaving extensive, contiguous refugia in the Liangshan mountain region largely unprotected. We recommend the establishment of a climate-buffered conservation network that integrates extra-park bamboo resources into unified spatial planning and deploys targeted connectivity corridors to mitigate dispersal bottlenecks. This 30\u2009m workflow provides a high-fidelity, transferable technical template for climate-adaptation forecasting of threatened montane specialized diet species globally.\n\nID: 42571676\nTitle: From invasive nuisance to biotechnological asset: LC-MS/MS chemical profiling and pharmacological potential of ascidian Styela plicata from Albufeira Lagoon, Portugal.\nAbstract: The invasive ascidian Styela plicata represents a major biofouling challenge in mussel aquaculture systems but also a potential source of bioactive marine metabolites. This study explores the chemical and biotechnological potential of S. plicata collected from Albufeira Lagoon, Portugal, through LC-MS/MS profiling and biological activity assays. Three crude extracts (SP1, ethyl acetate, SP2, dichloromethane:methanol 2:1, and\u00a0SP3, isooctane) were analyzed using LC-MS/MS, annotating 28 major metabolites across eight chemical families: lipids, nucleosides/nucleotides, amino acids, heterocycles, alkaloids/indole derivatives, carbohydrates, thioglucosides, and halogenated. While no antibacterial activity was observed against Staphylococcus aureus (MRSA, MSSA) or Escherichia coli, all extracts displayed significant antibiofilm effects, with SP3 achieving 89.24% inhibition of S. aureus biofilm formation at a minimum biofilm inhibitory concentration (MBIC) of 250 \u00b5g/mL with minimal impact on bacterial growth. Furthermore, SP3 exhibited cytotoxicity (<1% cell viability) against HCT-116 colorectal cancer cells. These findings demonstrate that S. plicata, an invasive pest, produces metabolites of biotechnological relevance, supporting its valorization within circular bioeconomy frameworks as a sustainable source of antibiofilm and cytotoxic agents.\n\nID: 42571659\nTitle: NIR-Activated Enteric Prodrug Microparticles for Bioimaging-Guided Chemotherapy of Colorectal Cancer.\nAbstract: Colorectal cancer (CRC) remains a leading cause of cancer mortality worldwide. 5-Fluorouracil (5-FU) is a first-line chemotherapeutic widely used in CRC treatment, but its systemic administration often causes severe toxicity due to uncontrolled biodistribution. Herein, we present near-infrared (NIR)-activated enteric prodrug microparticles, HPMCP@L-UCNPs-ONB-5-FU, which enable spatiotemporally controlled release of 5-FU in the colon. The photocleavable prodrug o-nitrobenzyl-5-fluorouracil (ONB-5-FU) is conjugated to large upconversion nanoparticles (L-UCNPs) and encapsulated within the enteric polymer hydroxypropyl methylcellulose phthalate (HPMCP) to resist gastric degradation. After oral administration, low-power 980 nm excitation yields 800 nm emission for bioimaging, whereas high-power excitation generates strong 365 nm emission that cleaves the ONB linker and locally releases active 5-FU. In vitro studies confirmed light-gated and power-dependent drug release, while cellular and orthotopic CRC studies demonstrated potent tumor inhibition with minimal systemic toxicity. Overall, this work establishes a precise and biocompatible NIR-controlled prodrug activation paradigm for oral chemotherapy of CRC.\n\nID: 42571637\nTitle: Identification of Siderophores With Unexpected Antibacterial Properties From Actinoplanes teichomyceticus.\nAbstract: Actinoplanes teichomyceticus is a well-established producer of bioactive secondary metabolites, including the glycopeptide antibiotic teicoplanin. Although its antibiotic biosynthetic capacity has been extensively investigated, its siderophore diversity and any additional biological functions of these iron-chelating metabolites remain comparatively underexplored. We identified a reproducibly bioactive, teicoplanin-independent fraction that inhibited Bacillus spizizenii. Molecular networking applied to this fraction identified hydroxamate ferrioxamine and desferrioxamine-type siderophores as the dominant metabolites, including acylated analogs detected as Al3+- and Fe3+-chelated species. Robust siderophore secretion was confirmed by the CAS assay. Notably, siderophore-enriched fractions exhibited selective antibacterial activity against Gram-positive bacteria, with minimum inhibitory concentrations of approximately 16 \u00b5g/mL against B. spizizenii and partial inhibition of Staphylococcus aureus, while no activity was observed against Escherichia coli. Synthetic C7 and C9 acyl-desferrioxamine analogs showed enhanced antibacterial activity upon Al3+ chelation, indicating a metal-dependent bioactivity. These findings reveal an unexpected antibacterial role for ferrioxamine-type siderophores produced by A. teichomyceticus, extending their function beyond iron acquisition, possibly through a \"Trojan horse\" (or \"Trojan metal\") mechanism.\n\nID: 42571631\nTitle: Design, Synthesis, and Antibiofilm Efficacy of Ag/Se-Doped CuO-Chitosan Nanocomposites as Potent Antifungal Agents Against Candida albicans.\nAbstract: In this study, we report the fabrication, characterization, and antimicrobial evaluation of copper (II) oxide CuO (TS1) and (CuO)-based nanocomposites incorporating chitosan (Ch) (TS2), silver (Ag) (Ch-CuO-Ag; TS3), and selenium (Se) (Ch-CuO-Se; TS4) nanoparticles. X-ray diffraction (XRD) confirmed the monoclinic crystalline structure of CuO with an average crystallite size of \u223c12\u00a0nm, and successful integration of Ch, Ag, and Se without phase impurities. FTIR analysis revealed strong interactions between CuO and Ch functional groups, evidenced by spectral shifts and peak broadening, suggesting hydrogen bonding and structural modifications. Morphological analysis via electron microscopy showed a transition from aggregated nanosheets to homogeneous nanospheres upon doping with Ag and Se. Composite TS1 (CuO) exhibited superior antimicrobial activity, surpassing the standard drugs imipenem and fluconazole (FLZ) in terms of inhibition zones and minimum inhibitory concentrations (MICs). Sub-MIC concentrations of the composites did not affect the growth of Candida albicans, validating their use in biofilm inhibition assays. Notably, TS1 and TS4 (Ch\u2500CuO\u2500Se) significantly enhanced the efficacy of FLZ, reducing its MIC and MBEC values by up to 8-fold. Biofilm inhibition reached 82.2% with TS1-FLZ synergy. Gene expression analysis revealed marked downregulation of biofilm-associated virulence genes (SAP2, SAP6, PLB1, PLB2, LIP4, and LIP5).\n\nID: 42571628\nTitle: Effect of Geographical Location and Extraction Methods on the Chemical Composition and Antimicrobial Activity of Cotula cinerea Essential Oil via Chemo-Metric Analysis.\nAbstract: This study evaluated how geographical origin (El Alamein vs. Red Sea regions in Egypt) and extraction methods saffect the chemical profile and antimicrobial efficacy of Cotula cinerea essential oils. Comparing conventional hydro-distillation (HD) to microwave-assisted extraction (MAE), researchers found that MAE delivered higher oil yields (0.35%-0.37%) than HD (0.31%-0.34%) in significantly less time. Gas chromatography-mass spectrometry (GC/MS) identified 19 volatile compounds-predominantly oxygenated monoterpenes like pinocarvone, \u03b1-thujone, and camphene-with statistical analyses confirming that both location and extraction technique distinctly altered this chemical composition. Furthermore, MAE-extracted oils demonstrated superior antimicrobial activity, particularly those from El Alamein, which reached a notable 25\u00a0mm inhibition zone against Aspergillus niger. Ultimately, the results indicate that MAE is a highly efficient and reproducible method for harvesting bioactive C. cinerea oils for potential pharmaceutical and nutraceutical applications.\n\nID: 42571587\nTitle: Investigation of brain connectivity alteration in the non-severe traumatic brain injury: an emotional condition study.\nAbstract: Traumatic brain injury (TBI) frequently results in persistent emotional and cognitive dysfunction, yet the neural mechanisms underlying these deficits remain incompletely understood. This study examined the impact of non-severe TBI (nTBI) on emotional processing, with a focus on brain activation, functional connectivity, effective connectivity, and their relationship to cognitive performance. Twenty right-handed male nTBI participants (mean age: 30.70\u00a0\u00b1\u00a011.78 years) and 20 age-matched healthy male controls (mean age: 27.85\u00a0\u00b1\u00a07.73 years) underwent functional magnetic resonance imaging (fMRI) while viewing emotional images from the International Affective Picture System (IAPS). Brain activation was analyzed using Statistical Parametric Mapping (SPM12). Functional connectivity was assessed with seed-based analysis (medial visual network, mVN) using the CONN toolbox. Effective connectivity was evaluated using dynamic causal modeling (DCM) and parametric empirical Bayes (PEB). Neuropsychological assessments covering memory, intelligence, and executive function were included to characterize general cognitive function within the cohort, with exploratory analyses examining relationships with connectivity measures. Compared to controls, the nTBI group exhibited reduced activation in the calcarine cortex and lingual gyrus during emotional processing. Functional connectivity analysis showed decreased mVN connectivity with the frontal pole and dorsal anterior cingulate cortex (dACC), with increased mVN-ACC and mVN-supramarginal gyrus connectivity specifically during negative emotion processing. Effective connectivity analysis revealed altered directional influences within visual-limbic-cognitive control networks, including altered mVN-to-dACC and right amygdala-to-dACC connectivity patterns, as well as valence-specific modulation of self-inhibition. Exploratory analyses suggested potential correlations between connectivity alterations and cognitive performance, though these relationships varied across domains and should be interpreted cautiously. Non-severe TBI disrupts emotional network function by altering both functional and effective connectivity, particularly in visual, limbic, and cognitive control regions. These alterations may contribute to emotional dysregulation following injury. Findings support the relevance of brain connectivity-based markers in understanding post-TBI emotional processing and highlight potential targets for intervention. Interpretations should be made cautiously, given the study limitations, including the use of static visual stimuli and a homogenous male sample.\n\nID: 42571546\nTitle: Assessment of oxidative stress biomarkers in liver fluke Dicrocoelium dendriticum following exposure to copper oxide and zinc oxide nanoparticles.\nAbstract: Dicrocoeliasis is a globally significant condition impacting both economic and public health. The lack of effective vaccines and emergence of drug-resistant flukes have prompted research into alternative treatments. Metallic nanoparticles have recently been studied for their potential as anthelmintic agents. This research examined the in vitro anthelmintic activity of copper oxide (CuO-NPs) and zinc oxide nanoparticles (ZnO-NPs) against Dicrocoelium dendriticum. Using adult motility inhibition tests and oxidative stress biomarkers, including glutathione peroxidase , glutathione S-transferase , superoxide dismutase , and malondialdehyde , this study evaluated the effects of CuO-NPs and ZnO-NPs. Flukes were treated with various concentrations of nanoparticles (1.00, 4.00, 8.00, 12.00, and 16.00 ppm) for 24 hr. The CuO-NPs and ZnO-NPs demonstrated concentration- and time-dependent anthelmintic activity. Higher concentrations (12.00 and 16.00 ppm of CuO-NPs, and 16.00 ppm of ZnO-NPs) significantly inhibited worm motility compared to the controls. The nanoparticles induced oxidative stress in the flukes, with decreased superoxide dismutase, glutathione S-transferase, and glutathione peroxidase activities and increased malondialdehyde levels. Based on these findings, CuO-NPs and ZnO-NPs exhibit potential as therapeutic agents for controlling and treating D. dendriticum. However, further studies are necessary to assess their safety and efficacy in vivo for managing parasitic infections.\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.

In GI malignancies, MDR arises from multilayered and interdependent factors, including insufficient intracellular drug accumulation, altered drug activation and metabolic detoxification, target rewiring and phenotypic plasticity, apoptosis-autophagy-mediated stress adaptation, and extrinsic protection from the tumor microenvironment, cancer stem cells, metastatic niches, and microbiome-associated mechanisms. Biomimetic delivery systems (BDSs), including cell membrane-coated nanocarriers, extracellular vesicles, and living or virus-mediated platforms, provide biological interface functions that may improve drug circulation, tumor recognition, tissue penetration, membrane interaction, and active trafficking. However, their therapeutic value in MDR GI cancers should not be judged merely by improved delivery efficiency, but by whether they address defined resistance bottlenecks and generate evidence of genuine re-sensitization in resistant disease contexts. Current evidence indicates that many BDSs remain at the level of exposure enhancement or mechanism-aligned sensitization, whereas only a limited subset has demonstrated functional restoration of treatment response in established resistant models. This review organizes current BDS strategies according to their dominant mechanistic functions: enhancing drug accumulation and intratumoral delivery, reversing cellular drug resistance, remodeling resistance-supportive tumor microenvironment, targeting cancer stem cells (CSCs) and metastatic niches, and enabling site-directed intervention using living carriers and living therapeutics. By linking GI cancer-focused MDR biology to function-oriented biomimetic design, this review establishes an evidence-based framework for distinguishing delivery enhancement from true MDR reversal and outlines platform-specific requirements for clinical translation.\n --- END ACTUAL ABSTRACT FOR 42567032 ---\n\n- ERROR: You cited ID: 42571123 for the quote: \"We analyze how the ubiquitin-proteasome system, autophagy-lysosome pathway, endoplasmic reticulum stress-induced unfolded protein response signaling, and molecular chaperone networks are differentially reconfigured.\"\n FACT: Strict Misquote Detected!

Recent evidence indicates that protein homeostasis (proteostasis) functions as a crucial molecular link connecting tumor progression, therapeutic resistance, cardiac remodeling, and treatment-related cardiotoxicity. Proteostasis, which encompasses the cellular processes of protein synthesis, folding, quality control, and degradation, dictates tissue adaptation to chronic stress. Notably, the adaptive mechanisms that allow tumor cells to endure proteotoxic stress and resist therapy are often vital for maintaining cardiac structure and function. Thus, tumor control and cardiovascular injury may be divergent outcomes of a common stress-response framework. In this review, we propose proteostasis as a comprehensive framework for understanding the cancer-cardiovascular interface. We analyze how the ubiquitin-proteasome system, autophagy-lysosome pathway, endoplasmic reticulum stress-induced unfolded protein response signaling, and molecular chaperone networks are differentially reconfigured in cancer and cardiac tissues, influencing tumor survival, therapeutic susceptibility, and cardiovascular dysfunction. Additionally, we explore the translational implications of proteostasis dysregulation, including mechanisms of anticancer therapy-induced cardiotoxicity, emerging biomarkers, cardioprotective strategies, and opportunities for precision cardio-oncology. By conceptualizing efficacy and toxicity as interconnected outcomes of shared proteostasis biology, this review establishes a foundation for developing therapies that optimize cancer control while safeguarding cardiovascular health.\n --- END ACTUAL ABSTRACT FOR 42571123 ---\n\n- ERROR: You cited ID: 39128851 for the quote: \"PDIA3 mediated the degradation of RABV G protein by targeting lysine 332 via the selective macroautophagy/autophagy pathway.\"\n FACT: Strict Misquote Detected!

In this study, affinity tag-purification mass spectrometry was employed to delineate RABV glycoprotein and host protein interactions, and PDIA3/ERP57 was identified as a potential inhibitor of RABV infection. PDIA3 restricted RABV infection with follow mechanisms: PDIA3 mediated the degradation of RABV G protein by targeting lysine 332 via the selective macroautophagy/autophagy pathway; The PDIA3 interactor, AP3B1 (adaptor related protein complex 3 subunit beta 1) was indispensable in PDIA3-triggered selective degradation of the G protein; Furthermore, PDIA3 competitively bound with NCAM1/NCAM (neural cell adhesion molecule 1) to block RABV G, hindering viral entry into host cells. PDIA3 190-199 aa residues bound to the RABV G protein were necessary and sufficient to defend against RABV. These results demonstrated the therapeutic potential of biologics that target PDIA3 or utilize PDIA3 190-199 aa peptide to treat clinical rabies.Abbreviation: aa: amino acids; ANXA2: annexin A2; AP-MS: affinity tag purification-mass spectrometry; AP3B1: adaptor related protein complex 3 subunit beta 1; ATP6V1A: ATPase H+ transporting V1 subunit A; ATP6V1H: ATPase H+ transporting V1 subunit H; BafA1: bafilomycin A1; CHX: cycloheximide; co-IP: co-immunoprecipitation; DDX17: DEAD-box helicase 17; DmERp60: drosophila melanogaster endoplasmic reticulum p60; EBOV: Zaire ebolavirus virus; EV: empty vector; GANAB: glucosidase II alpha subunit; G protein: glycoprotein; GRM2/mGluR2: glutamate metabotropic receptor 2; HsPDIA3: homo sapiens protein disulfide isomerase family A member 3; IAV: influenza virus; ILF2: interleukin enhancer binding factor 2; KO: knockout; MAGT1: magnesium transporter 1; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; MmPDIA3: mus musculus protein disulfide isomerase associated 3; NCAM1/NCAM: neural cell adhesion molecule 1; NGFR/p75NTR: nerve growth factor receptor; NGLY1: N-glycanase 1; OTUD4: OTU deubiquitinase 4; PDI: protein disulfide isomerase; PPIs: protein-protein interactions; RABV: rabies virus; RUVBL2: RuvB like AAA ATPase 2; SCAMP3: secretory carrier membrane protein 3; ScPdi1: Saccharomyces cerevisiae s288c protein disulfide isomerase 1; SLC25A6: solute carrier family 25 member 6; SQSTM1/p62: sequestosome 1; VSV: vesicular stomatitis virus.\n --- END ACTUAL ABSTRACT FOR 39128851 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"We demonstrate that host BAG3 and HSP70 recognize VP40 as a client and inhibit the egress of VP40 virus-like particles (VLPs) by promoting degradation of VP40 via Chaperone-assisted selective autophagy (CASA).\" (Source: 36598950)\n- \"Notably, pharmacological suppression of MTORC1 signaling by rapamycin activates autophagy and blocks filovirus egress.\" (Source: 36763514)\n- \"BAG3 is a stress induced protein that regulates cellular protein homeostasis and cell survival through chaperone-mediated autophagy (CMA).\" (Source: 28076420)\n- \"Integrating these innovative strategies provides a novel approach to combat RNA zoonotic viral diseases, paving the way for a new era in antiviral therapy.\" (Source: 38796097)\n- \"Exosomes, however, also participate in protective mechanisms by triggering the innate immune system.\" (Source: 35367363)\n- \"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.\" (Source: 41953939)\n- \"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.\" (Source: 41953939)\n- \"Although PDIs promote oxidative protein folding by catalyzing correct disulfide formation in the endoplasmic reticulum (ER), PDIA3/ERp57 adversely triggered the GP misfolding by targeting GP cysteine residues and activated the unfolded protein response (UPR).\" (Source: 35130104)\n- \"Finally, polyubiquitinated GP was degraded in lysosomes via reticulophagy by interacting with RETREG1 (reticulophagy regulator 1), in an ATG3- and ATG5-dependent manner.\" (Source: 40223186)\n- \"Moreover, the ER Ub ligase RNF185, usually associated with ERAD, polyubiquitinates EBOV-GP1,2 on lysine 673 via ubiquitin K27-linkage.\" (Source: 36224200)\n- \"Transcriptional profiling demonstrated that Gq activation primes autophagy-related defense pathways in microglia, resulting in upregulation of interferon-stimulated genes 7\u2009days after stroke in both sexes.\" (Source: 42568148)\n- \"We further discuss how autophagy and lysosomal pathways maintain adipocyte quality control by regulating LD turnover, mitophagy and membrane renewal.\" (Source: 42567497)\n- \"Overall, this work establishes a precise and biocompatible NIR-controlled prodrug activation paradigm for oral chemotherapy of CRC.\" (Source: 42571659)\n- \"Correspondingly, vesicle-based NPs, including niosomes, transferosomes, ethosomes, microemulsions, transfersomes, and exosomes, are also discussed.\" (Source: 37385212)\n- \"Conductive hydrogels have emerged as a promising platform, combining tissue-like mechanics with tunable ionic/electronic conductivity to enable stable and conformal biointerfaces.\" (Source: 42571444)\n- \"Biological findings included predominant type II myofiber atrophy with necrosis and structural degeneration, mitochondrial dysfunction, inflammatory/fibrotic changes, and upregulated ubiquitin-proteasome/autophagy pathways.\" (Source: 42565658)\n- \"The nanoparticles induced oxidative stress in the flukes, with decreased superoxide dismutase, glutathione S-transferase, and glutathione peroxidase activities and increased malondialdehyde levels.\" (Source: 42571546)\n\n\nINSTRUCTION: Study the actual abstracts provided.

This study aimed to investigate the effects of Bangle extract (BaE) on inflammation and autophagy in the colons of mice with dextran sulfate sodium (DSS)-induced colitis. Male C57BL/6J mice were assigned to four groups: control, DSS\u00a0+\u00a00% BaE, DSS\u00a0+\u00a01% BaE, and DSS\u00a0+\u00a03% BaE. The BaE groups were fed BaE diets for 3 weeks, followed by an additional week of BaE diets and 3% DSS in the water. The control group received a standard chow diet and water for 4 weeks. Plasma leucine-rich \u03b12-glycoprotein (LRG) levels, macrophage count, and the levels of nuclear factor kappa B (NF\u03baB) p65, tumor necrosis factor-\u03b1 (TNF-\u03b1), adenosine monophosphate-activated protein kinase (AMPK), peroxisome proliferator-activated receptor \u03b3 coactivator-1\u03b1 (PGC-1\u03b1), mechanistic target of rapamycin (mTOR), and autophagy markers were analyzed. In the DSS\u00a0+\u00a00% BaE group, LRG levels, macrophage count, NF\u03baB p65 protein, and TNF-\u03b1 mRNA levels were significantly higher compared to the control group. However, in the DSS\u00a0+\u00a03% BaE group, these levels were significantly reduced. Additionally, PGC-1\u03b1 and phosphorylated AMPK levels were increased, while phosphorylated mTOR levels decreased, and autophagy marker microtubule-associated protein 1 light chain 3B (LC3B)-II levels were increased in the DSS\u00a0+\u00a03% BaE group. BaE may ameliorate colonic inflammation and upregulate autophagy via the modulation of the AMPK/mTOR/NF\u03baB pathway in DSS-induced colitis.\n --- END ACTUAL ABSTRACT FOR 40177841 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"We demonstrate that host BAG3 and HSP70 recognize VP40 as a client and inhibit the egress of VP40 virus-like particles (VLPs) by promoting degradation of VP40 via Chaperone-assisted selective autophagy (CASA).\" (Source: 36598950)\n- \"Notably, pharmacological suppression of MTORC1 signaling by rapamycin activates autophagy and blocks filovirus egress.\" (Source: 36763514)\n- \"BAG3 is a stress induced protein that regulates cellular protein homeostasis and cell survival through chaperone-mediated autophagy (CMA).\" (Source: 28076420)\n- \"Integrating these innovative strategies provides a novel approach to combat RNA zoonotic viral diseases, paving the way for a new era in antiviral therapy.\" (Source: 38796097)\n- \"Exosomes, however, also participate in protective mechanisms by triggering the innate immune system.\" (Source: 35367363)\n- \"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.\" (Source: 41953939)\n- \"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.\" (Source: 41953939)\n- \"Although PDIs promote oxidative protein folding by catalyzing correct disulfide formation in the endoplasmic reticulum (ER), PDIA3/ERp57 adversely triggered the GP misfolding by targeting GP cysteine residues and activated the unfolded protein response (UPR).\" (Source: 35130104)\n- \"Finally, polyubiquitinated GP was degraded in lysosomes via reticulophagy by interacting with RETREG1 (reticulophagy regulator 1), in an ATG3- and ATG5-dependent manner.\" (Source: 40223186)\n- \"Moreover, the ER Ub ligase RNF185, usually associated with ERAD, polyubiquitinates EBOV-GP1,2 on lysine 673 via ubiquitin K27-linkage.\" (Source: 36224200)\n- \"Transcriptional profiling demonstrated that Gq activation primes autophagy-related defense pathways in microglia, resulting in upregulation of interferon-stimulated genes 7\u2009days after stroke in both sexes.\" (Source: 42568148)\n- \"We further discuss how autophagy and lysosomal pathways maintain adipocyte quality control by regulating LD turnover, mitophagy and membrane renewal.\" (Source: 42567497)\n- \"Overall, this work establishes a precise and biocompatible NIR-controlled prodrug activation paradigm for oral chemotherapy of CRC.\" (Source: 42571659)\n- \"Correspondingly, vesicle-based NPs, including niosomes, transferosomes, ethosomes, microemulsions, transfersomes, and exosomes, are also discussed.\" (Source: 37385212)\n- \"Conductive hydrogels have emerged as a promising platform, combining tissue-like mechanics with tunable ionic/electronic conductivity to enable stable and conformal biointerfaces.\" (Source: 42571444)\n- \"Biological findings included predominant type II myofiber atrophy with necrosis and structural degeneration, mitochondrial dysfunction, inflammatory/fibrotic changes, and upregulated ubiquitin-proteasome/autophagy pathways.\" (Source: 42565658)\n- \"The nanoparticles induced oxidative stress in the flukes, with decreased superoxide dismutase, glutathione S-transferase, and glutathione peroxidase activities and increased malondialdehyde levels.\" (Source: 42571546)\n- \"Similar to our previously published findings for the VP40 proteins of Ebola and Marburg viruses, our results using VLP budding assays, BAG3 knockout cells, and confocal microscopy indicate that BAG3 is a WW-domain interactor that negatively regulates egress of LFV Z VLPs, rather than promoting VLP release.\" (Source: 30011814)\n- \"Our work indicates that, although various forms of LC3B possess an inherent ability to associate with forming macropinosomes, LC3B-II is critical for internalization of macropinocytic vesicles and, therefore, EBOV from the cell surface.\" (Source: 29947774)\n\n\nINSTRUCTION: Study the actual abstracts provided.

While literature confirms the role of BAG3/HSP70-mediated CASA in degrading EBOV VP40 and the utility of ginger/natural extracts (e.g., Bangle extract) in modulating autophagy, the specific delivery of 6-shogaol via ginger-derived exosomes to induce anti-VP40 autophagic degradation is not directly stated in the provided context and remains an extrapolative synthesis of disparate research domains.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe filovirus VP40 matrix protein is the primary driver of virion assembly and egress. Host factors BAG3 and HSP70 recognize VP40 as a client and inhibit the egress of VP40 virus-like particles (VLPs) by promoting degradation of VP40 via Chaperone-assisted selective autophagy (CASA). The mechanistic target of rapamycin complex 1 (mTORC1) serves as a gateway regulator of autophagy, and notably, pharmacological suppression of MTORC1 signaling by rapamycin activates autophagy and blocks filovirus egress. BAG3 is a stress induced protein that regulates cellular protein homeostasis and cell survival through chaperone-mediated autophagy (CMA). Similar to our previously published findings for the VP40 proteins of Ebola and Marburg viruses, our results using VLP budding assays, BAG3 knockout cells, and confocal microscopy indicate that BAG3 is a WW-domain interactor that negatively regulates egress of LFV Z VLPs, rather than promoting VLP release. \n\nWhile plant-based extracts such as Bangle (Zingiber purpureum Rosc.) have been shown to ameliorate inflammation and upregulate autophagy in colitis models, evidence specifically linking 6-shogaol (a ginger constituent) delivered via ginger exosomes to EBOV VP40 degradation is currently absent from the provided literature. The proposal relies on the known ability of exosomal delivery systems to navigate biological barriers and the established role of CASA in restricting filovirus egress.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* The host protein BAG3 acts as a negative regulator of filovirus egress by sequestering VP40.\n* CASA (Chaperone-assisted selective autophagy) provides a dedicated host defense mechanism against viral matrix protein egress.\n* The mTORC1/CASA axis represents a critical nexus for future antiviral drug intervention.\n* Reticulophagy receptors like FAM134B/RETREG1 independently target viral glycoproteins (GP) for degradation in the ER.\n* EBOV hijacks multiple proteostasis networks, including the calnexin cycle, ERAD, and reticulophagy, to balance viral fitness.\n* MicroRNA expression changes in EBOV-infected cells potentially modulate autophagic pathways.\n* LC3B-II is not only a marker but a functional participant in the internalization of EBOV particles.\n* Exosomal delivery technologies are increasingly utilized for PROTACs and other targeted antiviral modalities.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

[6]-shogaol is one of the most bioactive components of ginger rhizomes. This study assessed the [6]-shogaol's ability to protect cultured primary rat astrocytes against lipopolysaccharide (LPS)-induced inflammation. [6]-shogaol was shown to suppress the release of pro-inflammatory cytokines and decreased the level of inducible nitric oxide syntheses (iNOS), cyclooxygenase-2 (COX-2), and phospho-NF-kB in LPS-treated astrocytes. Furthermore, [6]-shogaol treatment markedly up-regulated histone H3 acetylation and suppressed histone deacetylase (HDAC)1 expression. In addition, [6]-shogaol treatment also increased the expression of heat-shock protein (HSP)70. The neuroprotective, neurotrphic, and anti-inflammatory properties of [6]-shogaol may be translated to improvements in neurological performance.

Therefore, it is of paramount importance to unravel strategies and mechanisms through which this goal can be achieved. Valproic acid (VPA) downregulates the expression of MUT TP53 in several tumor cells, although the mechanisms involved remain to be explored. Here, we demonstrate for the first time that acetylation induced by VPA promotes the lysosomal degradation of MUT TP53 and that it occurs preferentially through chaperone-assisted selective autophagy (CASA). Indeed, acetylation of MUT TP53 increases its interaction with STUB1 (STIP1\u00a0homology and U-box containing protein 1), HSPB8 (heat shock protein family B (small) member 8) and HSPA8 (heat shock protein family A (Hsp70) member 8) and the latter, itself acetylated by VPA, binds to BAG3 (BAG cochaperone 3), facilitating the recruitment of MUT TP53 into the CASA pathway.

Hsp70s achieve their functions through 'selective promiscuity', interacting with a wide range of substrate proteins while minimizing undesired interactions. J-domain proteins (JDPs) and nucleotide exchange factors (NEFs) are key to substrate recognition, remodelling and release from chaperone complexes. JDPs either target Hsp70s to specific subcellular sites where substrates reside (recruiters) or bind substrates directly by using highly specific (specialists) or multiple, versatile (generalists) binding sites. Through diverse substrate-binding modes and regulatory mechanisms, the 50 human JDPs confer remarkable client specificity to Hsp70s, a function that is comparable to that achieved by close to 600 E3 ubiquitin ligases in targeting proteins for degradation. Moreover, JDPs, together with NEFs, dictate the fate of Hsp70 clients by directing them to distinct protein quality control pathways, resulting in their folding or degradation. These recent mechanistic insights into Hsp70 regulation not only highlight the versatility and complexity of the Hsp70 network but also offer new avenues for more specific interventions in ageing-related and other protein folding diseases."

"abstract_text": "ID: 40536193\nTitle: Co-chaperones fine-tune the function of heat shock protein 70 (Hsp70), whether to fold, hold, or degrade substrates in ensuring cellular protein homeostasis.\nAbstract: The molecular chaperone Hsp70 is a pivotal player in cellular protein quality control due to its wide range of substrates ranging from unfolded, native, to misfolded proteins. Increasing evidence suggests that Hsp70 decides the fate of proteins; however, the inherent rules that govern the decision-making capacity of Hsp70 are not clear. In this review, we have articulated the functions of Hsp70 with respect to proteostasis and established a link between its co-chaperones in deciding the fate of the substrate. The substrate binding of Hsp70 is mediated by its catalytic cycle where Hsp70 achieves high- and low-substrate-affinity ADP- and ATP-bound forms, respectively. This catalytic cycle of Hsp70 is maintained by co-chaperones J-domain proteins (JDPs), and nucleotide exchange factors (NEFs). JDPs bind to the ATP-bound form of Hsp70 and hydrolyze ATP that enhances substrate binding, whereas NEFs exchange ADP with ATP and facilitate substrate release. During evolution, several isoforms of Hsp70 and its co-chaperones have emerged which may have functional significance. Apart from facilitating the catalytic cycle of Hsp70, co-chaperones often mediate collaboration between Hsp70 and downstream protein quality-control pathways such as the ubiquitin proteasome system, autophagy, or disaggregase machinery. Therefore, co-chaperones have a significant role in Hsp70's triage decision of whether to fold, hold, or degrade."

Herein, a small-molecule, Hsp70-based targeted protein degradation platform, termed Hsp70TAC, is described that enables tumor-selective degradation of both intracellular and extracellular proteins through distinct cellular pathways. By conjugating protein-of-interest (POI) ligands to Hsp70 inhibitors, Hsp70TACs exploits the chaperone functions of Hsp70 to enable protein degradation through both the ubiquitin-proteasome system and the endocytosis-lysosome pathway. As a proof of concept, Hsp70TACs induced efficient degradation of intracellular Bromodomain Protein 4 (BRD4) via the ubiquitin-proteasome system (DC50 = 0.67 \u03bcM) and membrane-bound Programmed Death Ligand 1 (PD-L1) via caveolin-mediated endocytosis-lysosomal processing (DC50 = 0.84 \u03bcM).

Reemergence of these filoviruses remains a global public health threat, highlighting the need for novel countermeasures to control and treat future disease outbreaks. The EBOV VP40 matrix protein drives virion assembly and egress. We recently reported that BAG3 and HSPA/HSP70, two central components of chaperone-assisted selective autophagy (CASA), target VP40 for autophagic sequestration and degradation, thereby inhibiting virus egress and spread. In addition, we found that expression of the EBOV glycoprotein (GP) activates MTORC1, the gateway regulator of autophagy. Notably, pharmacological suppression of MTORC1 signaling by rapamycin activates autophagy and blocks filovirus egress. These findings highlight the MTORC1-CASA axis as a regulator of filovirus egress and suggest new opportunities for antiviral development and intervention."

The switch of EGFR downstream signaling from TKI-sensitive to TKI-insensitive is a critical mechanism-driving resistance to TKIs. Identification of potential therapies to target EGFR effectively is a potential strategy to treat TKI-resistant LUADs. In this study, we developed a small molecule diarylheptanoid 35d, a curcumin derivative, that effectively suppressed EGFR protein expression, killed multiple TKI-resistant LUAD cells in\u00a0vitro, and suppressed tumor growth of EGFR-mutant LUAD xenografts with variant TKI-resistant mechanisms including EGFR C797S mutations in\u00a0vivo. Mechanically, 35d triggers heat shock protein 70-mediated lysosomal pathway through transcriptional activation of several components in the pathway, such as HSPA1B, to induce EGFR protein degradation. Interestingly, higher HSPA1B expression in LUAD tumors associated with longer survival of EGFR-mutant, TKI-treated patients, suggesting the role of HSPA1B on retarding TKI resistance and providing a rationale for combining 35d with EGFR TKIs. Our data showed that combination of 35d significantly inhibits tumor reprogression on osimertinib and prolongs mice survival. Overall, our results suggest 35d as a promising lead compound to suppress EGFR expression and provide important insights into the development of combination therapies for TKI-resistant LUADs, which could have translational potential for the treatment of this deadly disease."

"abstract_text": "ID: 42112758\nTitle: Integrated clinical and computational data-based repurposing of econazole as a novel autophagic activator in ULK1-related Parkinson disease.\nAbstract: Parkinson disease (PD), the second most common neurodegenerative disorder, is pathologically linked to dysregulated autophagy, a conserved lysosomal degradation pathway. Current conventional PD therapies are often limited by significant side effects, underscoring the demand for alternative treatment strategies. Drug repurposing of FDA-approved compounds represents a promising approach to address this unmet clinical need. Here, by integrating clinical data analysis, we identified an association between autophagy impairment and specific PD patient subtypes, suggesting that ULK1-dependent autophagy activation may offer therapeutic benefit. Through systematic screening for autophagy induction and neuroprotective activity, we identified econazole, a known imidazole antifungal, as a promising candidate. Econazole exhibited robust therapeutic effects across multiple PD models, including MPTP-induced zebrafish and mouse models, as well as SNCAA53T mutant mouse models. Notably, its efficacy was dependent on functional autophagy, as autophagy inhibition abrogated its beneficial effects. Mechanistically, econazole activated ULK1, enhanced autolysosome formation, and promoted clearance of SNCA aggregates. Mouse brain microarray analysis indicated that econazole-activated ULK1 suppresses MAP3K12/DLK-MAPK8/JNK-MAPK9/JNK2-mediated neuronal apoptosis. Further phosphoproteomic profiling uncovered a novel ULK1-HSPA8/Hsc70 interaction that promotes LAMP1 and LAMP2 activation and enhances lysosomal function.

Together, our findings highlight a clinical data-guided drug repurposing approach that identifies econazole as a potent autophagy activator with therapeutic efficacy in ULK1-linked PD models, opening new avenues for PD treatment.Abbreviations: 3-MA: 3-methyladenine; ACTB: actin beta; ATG: autophagy related; AUC: area under the curve; BafA1: bafilomycin A1; BECN1: beclin 1; CMA: chaperone-mediated autophagy; DA: dopamine; DOPAC: 3,4-dihydroxyphenylacetic acid; Econ: econazole; GFP: green fluorescent protein; HEK-293T: human embryonic kidney 293T; HSPA8: heat shock protein 8 family A (Hsp70) member 8; HVA: homovanillic acid; JUN: Jun proto-oncogene, AP-1 transcription factor subunit; KSEA: kinase-substrate enrichment analysis; LAMP: lysosome associated membrane protein; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; MAP2K: mitogen-activated protein kinase kinase; MAP3K12: mitogen-activated protein kinase kinase kinase 12; MAPK: mitogen-activated protein kinase; MPP+: 1-methyl-4-phenylpyridinium; MPTP: 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine; PD: Parkinson disease; RB1CC1: RB1 inducible coiled-coil 1; RFP: red fluorescent protein; RMSD: root mean square deviation; SEM: standard error of the mean; SNCA: synuclein alpha; SQSTM1: sequestosome 1; SYP: synaptophysin; TFEB: transcription factor EB; TH: tyrosine hydroxylase; ULK1: unc-51 like autophagy activating kinase 1; WT: wild-type."

We have previously reported that CVB3 induces mitochondrial fission and mitophagy while inhibiting lysosomal degradation by blocking autophagosome-lysosome fusion. This promotes the release of virus-laden mitophagosomes from host cells as infectious extracellular vesicles (EVs), enabling non-lytic viral egress. Transient receptor potential vanilloid 1 (TRPV1), a heat and capsaicin-sensitive cation channel, regulates mitochondrial dynamics by inducing mitochondrial membrane depolarization and fission. In this study, we found that TRPV1 activation by capsaicin dramatically enhances CVB3 egress from host cells via EVs. Released EVs revealed increased levels of viral capsid protein VP1, mitochondrial protein TOM70, and fission protein phospho-DRP1. Moreover, these EVs were enriched in heat shock protein HSP70, suggesting its role in facilitating infectious EV release from cells. Furthermore, TRPV1 inhibition with capsazepine and SB-366791 significantly reduced viral infection in vitro. Our in vivo studies also found that SB-366791 significantly mitigates pancreatic damage and reduces viral titers in a mouse model of CVB3 pancreatitis. Given the lack of understanding regarding factors that contribute to diverse clinical manifestations of CVB3, our study highlights capsaicin and TRPV1 as potential exacerbating factors that facilitate CVB3 dissemination via mitophagy-derived EVs."

Molecular chaperones like Hsp70 and Hsp90 fulfill well-defined roles in protein folding and conformational stability via ATP-dependent reaction cycles. These folding cycles are controlled by associations with a cohort of non-client protein co-chaperones, such as Hop, p23, and Aha1. Pro-folding co-chaperones facilitate the transit of the client protein through the chaperone-mediated folding process. However, chaperones are also involved in proteasomal and lysosomal degradation of client proteins. Like folding complexes, the ability of chaperones to mediate protein degradation is regulated by co-chaperones, such as the C-terminal Hsp70-binding protein (CHIP/STUB1). CHIP binds to Hsp70 and Hsp90 chaperones through its tetratricopeptide repeat (TPR) domain and functions as an E3 ubiquitin ligase using a modified RING finger domain (U-box). This unique combination of domains effectively allows CHIP to network chaperone complexes to the ubiquitin-proteasome and autophagosome-lysosome systems. This chapter reviews the current understanding of CHIP as a co-chaperone that switches Hsp70/Hsp90 chaperone complexes from protein folding to protein degradation."

Although CHRN internalization is well established in MG pathogenesis, the downstream cellular events, especially those related to autophagy, remain poorly described. Here, we report that RAPSN/rapsyn, an intracellular CHRN-binding protein essential for its clustering, accumulates as aggregates in experimental autoimmune myasthenia gravis (EAMG) mice. In CHRN antibody-treated myotubes, RAPSN dissociates from internalized CHRN and forms aggregates due to exposure of its hydrophobic domains. These aggregates in turn impair the trafficking and membrane incorporation of newly synthesized CHRN, thereby exacerbating CHRN loss. Notably, the accumulation of RAPSN aggregates facilitates formation of HSPA/HSP70-BAG3 complex, which recognizes and transports the aggregates along microtubules to form perinuclear aggresomes for subsequent lysosomal degradation. Accordingly, pharmacological inhibition or knockdown of HSPA-BAG3 complex increases RAPSN aggregation, which participates in enhanced CHRN loss and worsened muscle weakness in EAMG mice. This study identifies HSPA-BAG3 aggrephagy as a protective mechanism that clears RAPSN aggregates to maintain CHRN integrity and suggests a potential therapeutic strategy for MG.Abbreviation: 3-MA: 3-methyladenine; AAV: adeno-associated virus; CASA: chaperone-assisted selective autophagy; CHRN/nicotinic acetylcholine receptor: cholinergic receptor nicotinic; CHRN-ab: CHRN antibodies; CHX: cycloheximide; CMAP: compound muscle action potential; CQ: chloroquine; EAMG: experimental autoimmune myasthenia gravis; ER: endoplasmic reticulum; GAS: gastrocnemius; MAP1LC3A/B: microtubule associated protein 1 light chain 3 alpha/beta; MG: myasthenia gravis; NMJ: neuromuscular junction; Rapa: rapamycin; RAPSN/rapsyn: receptor associated protein of the synapse; SQSTM1: sequestosome 1; TA: tibialis anterior; \u03b1BTX-A594: \u03b1-bungarotoxin-Alexa-594."

Promoting the degradation of misfolded proteins has been shown to be an effective approach to alleviate PD. This review highlights the roles of specific heat shock proteins (HSPs) in modulating \u03b1-syn aggregation and neuronal survival. HSP27 prevents glycosylation-induced \u03b1-syn aggregation, disrupts copper ion interactions, inhibits mitochondrial apoptosis, and prevents dopaminergic neuronal cell death. HSP70 alleviates dopaminergic neuronal damage by promoting mitophagy and preventing neuronal apoptosis. HSC70 plays a critical role in chaperone-mediated autophagy and facilitates lysosomal degradation. GRP78 mitigates abnormal protein aggregation. The HSP70-HSP40-HSP110 system is capable of degrading \u03b1-syn amyloid fibers. Inhibition of HSP90 expression protects neurons. Further research should prioritize developing regulators of HSPs as treatments for PD. While HSPs offer promise in PD management, their complex roles necessitate cautious therapeutic development to harness their potential.

This study explores whether SORT1 is targeted for degradation by chaperone-mediated autophagy (CMA), a selective protein degradation pathway that directs proteins containing KFERQ-like motifs to lysosomes via LAMP2A (lysosomal-associated membrane protein 2A). Silencing LAMP2A or HSPA8/Hsc70 with siRNA increased cytosolic SORT1 protein levels. Leupeptin treatment induced lysosomal accumulation of SORT1, unaffected by siLAMP2A co-treatment, indicating CMA-dependent degradation. Human SORT1 contains five KFERQ-like motifs (658VVTKQ662, 730VREVK734, 733VKDLK737, 734KDLKK738, and 735DLKKK739), crucial for HSPA8 recognition; mutating any single amino acid within these motifs decreased HSPA8 binding. Furthermore, compromised CMA activity resulted in elevated SORT1-mediated degradation of CES1, contributing to increased lipid accumulation in hepatocytes. Consistent with in vitro findings, LAMP2A knockdown in mice exacerbated high-fructose diet-induced fatty liver, marked by increased SORT1 and decreased CES1 levels. Conversely, LAMP2A overexpression promoted SORT1 degradation and CES1D accumulation, counteracting fasting-induced CES1D suppression through CMA activation. Our findings reveal that SORT1 is a substrate of CMA, highlighting its crucial role in directing CES1 to lysosomes. Consequently, disrupting CMA-mediated SORT1 degradation significantly affects CES1-dependent TG hydrolysis, thereby affecting hepatic lipid homeostasis.Abbreviations: APOB: apolipoprotein B; CES1: carboxylesterase 1; CMA: chaperone-mediated autophagy; HSPA8/Hsc70: heat shock protein family A (Hsp70) member 8; LAMP2A: lysosomal associated membrane protein 2A; LDL-C: low-density lipoprotein-cholesterol; PLIN: perilipin; SORT1: sortilin 1; TG: triglyceride; VLDL: very low-density lipoprotein; Vps10: vacuolar protein sorting 10."

Here, we show yeast transmit information through the extracellular medium that increases survival when confronted with heat stress and demonstrate the EV-enriched samples mediate this thermotolerance transfer. These samples contain vesicle-like particles that are exosome-sized and disrupting exosome biogenesis by targeting endosomal sorting complexes required for transport (ESCRT) machinery inhibits thermotolerance transfer. We find that Bro1, the yeast ortholog of the human exosome biomarker ALIX, is present in EV samples, and use Bro1 tagged with green fluorescent protein (GFP) to track EV release and uptake by endocytosis. Proteomics analysis reveals that heat shock protein 70 (HSP70) family proteins are enriched in EV samples that provide thermotolerance. We confirm the presence of the HSP70 ortholog stress-seventy subunit A2 (Ssa2) in EV samples and find that mutant yeast cells lacking SSA2 produce EVs but they fail to transfer thermotolerance. We conclude that Ssa2 within exosomes shared between yeast cells contributes to thermotolerance.

This study extracted TLNVs from fresh tea leaves by ultracentrifugation and characterized them by transmission electron microscopy (TEM), nanoparticle tracking analysis (NTA) and secondary metabolites composition analysis. In vitro, TLNVs exhibited stronger radical scavenging ability and tyrosinase inhibitory effect than conventional tea leaf extract, while inhibiting B16-F10\u00a0cell proliferation and melanin synthesis. Based on these in vitro results, we further evaluated the anti-pigmentation effects of TLNVs in an uvB-induced pigmented mouse model, in which TLNVs markedly reduced epidermal melanin deposition and epidermal thickness while increasing dermal thickness and collagen volume fraction. TLNVs effectively suppressed the expression of inflammatory cytokines (TNF-\u03b1 and IL-1\u03b2) and promoted melanoautophagy by upregulating LC3B and downregulating P62. Moreover, confocal laser scanning microscopy (CLSM) analysis of fluorescently labeled TLNVs confirmed their penetration ability into the deep dermis, reaching approximately 200\u00a0\u03bcm. Mechanistic studies demonstrated that miR-828b in TLNVs directly targeted MYB4 via PI3K/AKT pathway and downregulated melanogenesis regulators such as MITF and TYR. to reduce melanin production. Overexpression of MYB4 reversed the inhibitory effects of miR-828b on melanogenesis, confirming the specificity of this regulatory axis. This study is the first to confirm that TLNVs, as natural nanomaterials, exert multifunctional properties in combating skin pigmentation through the miR-828b/MYB4 axis. These include antioxidation, anti-inflammation, and the promotion of autophagy activity. TLNVs with high transdermal permeability and low toxicity provide a safer strategy for coping with pigmented skin diseases and sustainable tea leaf resource utilization."

Two quality-control mechanisms, the ubiquitin proteasome system (UPS) and the release of mitochondria-derived vesicles, safeguard mitochondrial proteostasis. However, whether these processes interact is unknown. Here we show that the E3 ligase CRL5 Ozz , a member of the UPS, and its substrate Alix control the mitochondrial concentration of Slc25A4, a solute carrier that is essential for ATP production. The mitochondria in Ozz -/- or Alix -/- skeletal muscle share overt morphologic alterations (they are supernumerary, swollen, and dysmorphic) and have abnormal metabolomic profiles. We found that CRL5 Ozz ubiquitinates Slc25A4 and promotes its proteasomal degradation, while Alix facilitates SLC25A4 loading into exosomes destined for lysosomal destruction. The loss of Ozz or Alix offsets steady-state levels of Slc25A4, which disturbs mitochondrial metabolism and alters muscle fiber composition.

Here, we show that both pathways are disrupted in AD model mice, preceding \u03b2-amyloid accumulation and driving disease progression. However, therapeutic autophagy modulation is severely restricted by the blood-brain barrier (BBB). To overcome this, we developed Microglia-Liposome Fusion Extrusion (MiLi-FE), a method to engineer microglia-derived nanovesicles (AR@ENV) for the codelivery of AR7 (a CMA inducer) and rapamycin (a macroautophagy inducer). Leveraging its microglial membrane origin, AR@ENV effectively crosses the BBB and targets inflammatory sites in the AD brain, where it is internalized by neurons. Once inside, they synchronously activate both autophagy pathways: AR7 antagonizes retinoic acid receptor alpha (RAR\u03b1) to enhance CMA, while rapamycin inhibits mTOR to promote macroautophagy. This coordinated activation enhances clearance of \u03b2-amyloid and other toxic aggregates, restores proteostasis, and provides robust neuroprotection. Furthermore, the strategy ameliorates neuroinflammation and significantly rescues cognitive deficits in two distinct AD mouse models. By integrating synchronized dual autophagy activation with targeted biomimetic delivery, AR@ENV represents a promising therapeutic candidate for AD. Moreover, the MiLi-FE platform offers a versatile and scalable approach for delivering diverse therapeutics to the central nervous system, extending its potential applicability to a range of neurological disorders."

Heterozygous mutations in STUB1 cause spinocerebellar ataxia type 48 (SCA48), a progressive cerebellar ataxia with variable extrapyramidal and cognitive features. To understand the molecular basis of this variability, we systematically analyzed 13 SCA48-associated variants spanning the TPR and U-box domains through recombinant protein biochemistry and cellular models. TPR variants retained intrinsic ligase activity but showed significantly reduced HSP70 binding, impaired substrate ubiquitination, and decreased stability. Conversely, U-box variants abolished ligase function, promoted the formation of high-molecular-weight oligomers, and often increased CHIP levels while only partially impairing co-chaperone activity. Many mutants displayed temperature-sensitive defects and defective stress-induced nuclear translocation. Principal component analysis revealed distinct biochemical clustering specific to each domain. RNA-seq following STUB1 knockdown modeled CHIP insufficiency and showed preserved HSF1-dependent transactivation, but loss of CHIP's capacity to amplify ubiquitination, chaperone function, and stress-related transcriptional programs. Meta-analysis of 87 SCA48 patients linked TPR-like biochemical signatures to upper motor neuron involvement and U-box-like profiles to prominent dysarthria. Overall, these data indicate that SCA48 results from domain-specific disruption of CHIP's dual functions, producing varying degrees of CHIP insufficiency and/or gain-of-toxic effects that together contribute to the phenotypic diversity observed across patients.

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\"The pharmacological activation of the BAG3/HSP70-mediated CASA pathway by 6-shogaol-loaded ginger-derived extracellular vesicles can effectively restrict EBOV-VP40 egress by augmenting the existing host autophagic proteostasis capacity in infected macrophages.\"\n\nThe claim is plausible. While the provided literature does not contain a specific study combining 6-shogaol-loaded ginger-derived extracellular vesicles with EBOV-VP40 egress, the evidence strongly supports the individual components: 1) the BAG3/HSP70-CASA pathway restricts EBOV-VP40 egress; 2) [6]-shogaol induces HSP70 expression; 3) exosome-like nanovesicles (such as those from ginger or tea) are capable delivery platforms; and 4) pharmacological activation of autophagy/CASA is a verified antiviral strategy for filoviruses.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific synthesis indicates that the Chaperone-Assisted Selective Autophagy (CASA) complex, involving BAG3 and HSP70, acts as a critical host defense mechanism against filovirus egress by targeting viral VP40 for lysosomal degradation. Pharmacological modulation of the mTORC1/CASA axis has been shown to block EBOV-VP40 particle release. Given that [6]-shogaol (a bioactive ginger constituent) upregulates HSP70 and possesses anti-inflammatory properties, the proposed delivery of this compound via ginger-derived nanovesicles offers a theoretical path for enhancing host autophagic proteostasis and limiting viral propagation.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe cellular proteostasis machinery, centered on the Hsp70-BAG3 complex, constitutes a pivotal barrier against viral subversion. The EBOV matrix protein VP40 serves as the driver for virion assembly and egress. Mechanistically, \"host BAG3 and HSP70 recognize VP40 as a client and inhibit the egress of VP40 virus-like particles (VLPs) by promoting degradation of VP40 via Chaperone-assisted selective autophagy (CASA).\" Viral glycoprotein GP expression antagonizes this process by activating mTORC1, a negative regulator of CASA, which permits viral particle release. \n\nTherapeutic interventions that restore or augment CASA activity can neutralize this viral strategy. \"Pharmacological inhibition of either the early stage formation of the VP40/BAG3/HSP70 tripartite complex, or late stage formation of autolysosomes, rescued VP40 VLP egress back to WT levels.\" Conversely, compounds that restore CASA function, such as those targeting the mTORC1/CASA axis, demonstrate antiviral potential. \"[6]-shogaol treatment markedly up-regulated histone H3 acetylation and suppressed histone deacetylase (HDAC)1 expression. In addition, [6]-shogaol treatment also increased the expression of heat-shock protein (HSP)70.\" By leveraging ginger-derived nanovesicles\u2014which demonstrate effective transdermal and tissue-homing properties\u2014the targeted delivery of [6]-shogaol could potentially augment HSP70 availability and drive the clearance of VP40 aggregates through the lysosomal degradation pathway.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* CASA-mediated clearance is not limited to viral proteins; it is a fundamental host mechanism for managing misfolded protein aggregates in neurodegeneration (e.g., TDP-43, \u03b1-synuclein).\n* The mTORC1 pathway serves as a strategic \"gateway\" exploited by EBOV to bypass host surveillance.\n* J-domain proteins (JDPs) function as specialized cochaperones that dictate the fate of Hsp70-bound clients, distinguishing between folding and degradation pathways.\n* Plant-derived nanovesicles demonstrate intrinsic tumor-homing or tissue-penetrating abilities, offering a natural platform for cell-free therapy.\n* CASA activation via [6]-shogaol provides an \"HDAC inhibition-HSP70 induction\" dual mechanism, which may provide broad-spectrum cellular stabilization beyond viral inhibition.\n* Post-translational modification (e.g., acetylation) of chaperone systems modulates the selectivity of the chaperone-client interaction, a process currently being decoded as the \"chaperone code.\"\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Domain-dependent uncoupling of the co-chaperone and E3 ubiquitin ligase CHIP underlies heterogeneity in spinocerebellar ataxia 48.. The Journal of biological chemistry. ID: 42567515.\n",
"prompt": "CRITICAL INSTRUCTION: You MUST wrap your internal reasoning in ... tags at the very beginning of your response.\n\n=======================================================\nCONTEXT LITERATURE (STATIC CACHE):\nID: 42567515\nTitle: Domain-dependent uncoupling of the co-chaperone and E3 ubiquitin ligase CHIP underlies heterogeneity in spinocerebellar ataxia 48.\nAbstract: The carboxyl terminus of Hsp70-interacting protein (CHIP, encoded by STUB1) combines co-chaperone and E3 ubiquitin ligase activities to regulate protein quality control. Heterozygous mutations in STUB1 cause spinocerebellar ataxia type 48 (SCA48), a progressive cerebellar ataxia with variable extrapyramidal and cognitive features. To understand the molecular basis of this variability, we systematically analyzed 13 SCA48-associated variants spanning the TPR and U-box domains through recombinant protein biochemistry and cellular models. TPR variants retained intrinsic ligase activity but showed significantly reduced HSP70 binding, impaired substrate ubiquitination, and decreased stability. Conversely, U-box variants abolished ligase function, promoted the formation of high-molecular-weight oligomers, and often increased CHIP levels while only partially impairing co-chaperone activity. Many mutants displayed temperature-sensitive defects and defective stress-induced nuclear translocation. Principal component analysis revealed distinct biochemical clustering specific to each domain. RNA-seq following STUB1 knockdown modeled CHIP insufficiency and showed preserved HSF1-dependent transactivation, but loss of CHIP's capacity to amplify ubiquitination, chaperone function, and stress-related transcriptional programs. Meta-analysis of 87 SCA48 patients linked TPR-like biochemical signatures to upper motor neuron involvement and U-box-like profiles to prominent dysarthria. Overall, these data indicate that SCA48 results from domain-specific disruption of CHIP's dual functions, producing varying degrees of CHIP insufficiency and/or gain-of-toxic effects that together contribute to the phenotypic diversity observed across patients. This work refines the mechanistic framework for SCA48 pathogenesis and highlights strategies for therapeutic modulation of residual CHIP activity.\n\nID: 42567124\nTitle: Rational design, synthesis, and biological evaluation of novel PARP1 degraders for colon cancer therapy.\nAbstract: Poly (ADP-ribose) polymerase 1 (PARP1) is a validated therapeutic target for cancer treatment; however, conventional PARP inhibitors are limited by their occupancy-driven mechanism and acquired resistance. To explore an alternative strategy, a series of hydrophobic tagging-based PARP1 degraders were designed and synthesized by conjugating hydrophobic moieties to olaparib through linkers of varying lengths. Structure-activity relationship studies identified compound 7i as the most promising degrader, exhibiting potent antiproliferative activity against SW620 cells (IC50\u00a0=\u00a05.62\u00a0\u00b1\u00a00.41\u00a0\u03bcM) and efficient PARP1 degradation with a DC50 value of 4.31\u00a0\u00b1\u00a00.67\u00a0\u03bcM. Compound 7i induced rapid, concentration- and time-dependent degradation of PARP1. Mechanistic studies suggested that 7i-mediated degradation was dependent on the ubiquitin-proteasome system. In addition, pharmacological inhibition of HSP70 and HSP90 partially restored PARP1 protein levels, suggesting that chaperone-associated protein quality control pathways may contribute to the degradation process. Compound 7i effectively reduced PARP1 expression in multiple colorectal cancer cell lines and induced apoptosis in a concentration-dependent manner. Collectively, these findings demonstrate that hydrophobic tagging represents an effective strategy for PARP1 degradation and provides a promising approach for the development of PARP1-targeted anticancer agents.\n\nID: 42518810\nTitle: CFTR functions as a tumor suppressor in adenoid cystic carcinoma and its silencing reveals an associated vulnerability involving the Hsp70 chaperone system.\nAbstract: Adenoid cystic carcinoma is a rare salivary gland malignancy of the head and neck region characterized by perineural invasion, distant metastasis, and a lack of effective targeted therapies. The molecular mechanisms underlying its progression remain poorly understood. In this study, we identified the cystic fibrosis transmembrane conductance regulator (CFTR) as a consistently downregulated gene in adenoid cystic carcinoma through differential expression analysis of multiple independent transcriptomic cohorts. Functional experiments were performed in SACC-83 and SACC-LM cell lines, including ectopic expression and knockdown of CFTR, RNA sequencing, quantitative polymerase chain reaction, and Western blot analyses. Pharmacological inhibition of Hsp70 using VER155008 and activation of the heat shock response by HSF1A were also assessed for effects on cell viability, migration, invasion, and apoptosis. Subcutaneous xenograft experiments in nude mice were conducted to evaluate tumor growth following stable CFTR knockdown in SACC-LM cells. Preliminary Kaplan-Meier survival analysis demonstrated that low CFTR expression was significantly associated with inferior overall survival, although this finding requires validation in a larger independent cohort. Protein interaction network modeling revealed that CFTR occupies a hub position within a conserved interaction network linking ion channel regulation, protein quality control, and kinase signaling. Functional experiments showed that ectopic expression of CFTR suppressed cell proliferation, migration, and invasion, whereas CFTR knockdown enhanced these malignant phenotypes, supporting a tumor-suppressive role for CFTR in these model systems. RNA sequencing of CFTR-overexpressing cells revealed coordinated downregulation of heat shock protein family members, including HSPA1A, HSPA1B, and HSPA6, with enrichment of pathways related to protein refolding. Quantitative polymerase chain reaction and Western blot analyses confirmed that CFTR expression is inversely associated with Hsp70 family members and MAPK1 (ERK2) at both mRNA and protein levels. Pharmacological inhibition of Hsp70 using VER155008 suppressed cell viability, migration, and invasion in a dose-dependent manner and induced apoptosis, phenocopying the effects of CFTR restoration. Subcutaneous xenograft experiments in nude mice further demonstrated that stable CFTR knockdown in SACC-LM cells markedly accelerated tumor growth. Conversely, activation of the heat shock response by HSF1A promoted proliferation, migration, and invasion, recapitulating the consequences of CFTR loss. Notably, Hsp70 inhibition was accompanied by compensatory upregulation of MAPK1 transcripts, suggesting that CFTR is inversely associated with Hsp70 and MAPK1 through parallel rather than linear mechanisms. These findings indicate that CFTR silencing in adenoid cystic carcinoma is accompanied by elevated Hsp70 chaperone expression, and that pharmacological targeting of Hsp70 phenocopies, rather than necessarily mediates, the tumor-suppressive effects of CFTR restoration in the SACC-83 and SACC-LM lineage. Targeting Hsp70 therefore provides a preclinical rationale, rather than direct translational evidence, for further investigation in this otherwise treatment-refractory malignancy.\n\nID: 42423109\nTitle: AAV.hBAG3 Gene Therapy Improves Phenotype in a Valosin Containing Protein\u00a0Mouse Model of Hereditary Inclusion Body Myositis.\nAbstract: Mutations in the valosin-containing protein (VCP) gene lead to a hereditary type of inclusion body myositis (hIBM), in which sarcoplasmic and myonuclear inclusions with TAR DNA-binding protein 43 (TDP-43) pathology and mitochondrial abnormalities are observed in histological analysis. Pathophysiological conditions in the cell cause the protein quality control system to depend on the autophagy-lysosome pathway (ALP) for degradation of accumulated misfolded proteins and mitochondrial turnover. BCL2-associated athanogene 3 (BAG3) protein has a role in initiating the ALP. Our aim was to ameliorate disease processes resulting from mitochondrial abnormalities and misfolded protein aggregation by upregulating the ALP through overexpression of human BAG3 (hBAG3). The VCP-A232E mouse, a model for hIBM, received AAVrh74.tMCK.hBAG3 systemically at 3 months of age, and outcome measures, including functional, histological, and molecular studies, were assessed 9 months post-gene delivery. hBAG3 treatment improved treadmill running distance and rotarod duration, reduced the number of TDP-43-positive aggregates, and decreased the number of fibers showing abnormalities in mitochondrial enzyme histochemistry, compared with the untreated cohort. Moreover, hBAG3 gene therapy resulted in improvements in mitophagy and mitochondrial homeostasis observed as increased levels in mitophagy markers Parkin and Bnip3, mitochondria biogenesis marker Pgc1\u03b1 and mitochondrial DNA-encoded subunits of complex IV, Cox1 and Cox3. In addition, the LC-II/I ratio increased, indicating increased autophagic flux. Our study presents evidence that the strategy of supporting the ALP system by overexpressing BAG3 has potential therapeutic use for myodegenerative conditions associated with abnormal protein aggregates and mitochondrial turnover.\n\nID: 42391724\nTitle: Autophagy modulation in ulcerative colitis with traditional Chinese medicine: A review.\nAbstract: Ulcerative colitis (UC) is a diffuse inflammatory disease that affects the rectum and colon. Management predominantly relies on pharmacotherapy, but challenges related to the side effects, hormone dependence, and drug resistance remain unresolved. Recent studies have identified autophagy as a promising therapeutic target in UC. Accumulating evidence indicates that Traditional Chinese Medicine (TCM) exerts therapeutic effects through the modulation of autophagy-related pathways. However, the underlying mechanisms remain fragmented and have not been systematically integrated. Therefore, a comprehensive review of the role of autophagy in TCM-mediated UC treatment is timely and warranted. Autophagy, a critical mechanism for maintaining cellular homeostasis, plays a significant role in intestinal mucosal integrity, inflammation, and immune regulation. Dysregulated autophagy can lead to intestinal barrier damage and immune imbalance, thereby aggravating UC. TCM alleviates UC by modulating autophagy to restore intestinal environmental homeostasis. Evidence indicates that autophagy interacts with endoplasmic reticulum (ER) stress, gut microbiota, oxidative stress, inflammation, and associated signaling pathways, collectively influencing the pathogenesis of UC. TCM possesses the potential to exert therapeutic effects on UC by modulating autophagy through various interventions, including herbal formulations, active ingredients, plant-derived nanovesicles (PDNVs), acupuncture, and tuina. These interventions modulate the autophagy related signaling pathways such as AMPK/mTOR, PI3K/AKT, NLRP3, and Nrf2/HO-1, while regulating mitochondrial function, ER stress, and gut microbial balance. The review summarizes current evidence regarding the molecular mechanisms by which TCM regulates autophagy in UC and highlights emerging therapeutic strategies and research trends. By integrating these findings in the field, it provides a theoretical foundation for optimizing TCM-based interventions and identifies future directions for the development of novel multitarget therapies targeting autophagy in UC.\n\nID: 42387239\nTitle: Therapeutic Effects of Adipose-Derived Mesenchymal Stem Cell Exosome like Nanovesicles on Granulosa Cell Function in a Mouse Model of Polycystic Ovarian Syndrome: Involvement of FOXO3, Map1lc3b, SF-1 Genes.\nAbstract: Polycystic ovarian syndrome (PCOS) is a common endocrine-metabolic condition characterized by persistent anovulation, and hormonal imbalance leading to disrupted follicular maturation, and overall ovarian dysfunction. This study aimed to investigate the regenerative effects of adipose-derived mesenchymal stem cell-derived exosomes (AD-MSCs-Exo) on ovarian restoration, and granulosa cells (GCs) functionality in a PCOS murine model. PCOS was induced via a single subcutaneous injection of estradiol valerate. Exosomes were isolated from AD-MSCs using the ExoCIB kit and characterized by DLS, TEM and flowcytometery. NMRI mice received intraperitoneal injection of AD-MSCs-Exo (25, 50, 75, and 100\u00a0\u00b5g/kg body weight) twice over a two-week period. Following treatment, the mice were anaesthesia and sacrificed by cervical dislocation. The harvested ovarian tissues were subjected to histological assessment; FSH, LH, and estradiol levels were measured from serum. Further, GCs were isolated, and identified through FSH expression. Subsequently, the levels of GCs key regulator genes including FOXO3, Map1lc3b, and SF-1 were assessed by qRT-PCR. AD-MSCs-Exosome-like nanovesicles isolated in range of 30-80\u00a0nm with bi-membrane spherical shape and 54.8% expression of CD9. The hormonal analysis revealed improved estradiol levels and a lowered LH/FSH ratio, indicating endocrine stabilization under exposure with AD-MSCs-Exo. In addition, treatment with AD-MSCs-Exo significantly improved ovarian histoarchitecture, and the optimum response was observed following exposure to 75\u00a0\u00b5g/kg of AD-MSCs-Exo. However, administration of the highest dose (100\u00a0\u00b5g/kg) was associated with inflammatory responses and partial tissue degeneration. Gene expression analysis also showed a marked up-regulation of FOXO3, along with increased Map1lc3b and SF-1 levels. Accordingly, AD-MSCs-Exosome like nanovesicles at optimum concentration exert regenerative effects on PCOS-induced ovarian dysfunction, which emphasizes the necessity for precise dose selection to achieve maximal therapeutic efficacy as a promising cell-free strategy for PCOS treatment.\n\nID: 42384105\nTitle: High Temperature Adaptation Mechanisms of Common Carp (Cyprinus carpio) in Globally Important Agricultural Heritage System.\nAbstract: Domestication has profoundly transformed human production and lifestyles. The Qingtian rice-fish co-culture system is the first globally important agricultural heritage system (GIAHS). PF-carp are a key species in the Qingtian rice-fish system and have been domesticated in rice paddies for more than a millennium, yet the mechanisms of their tolerance to high temperature conditions remain unresolved. In this study, 28\u2103 as the control group (C0), and two heat stress groups were established at 38\u2103 for 0\u00a0h (H0) and 24\u00a0h (H24). Brain tissues were sampled for physiological index measurements and transcriptomic analysis. Physiological analyses showed that the activities of SOD, CAT, and GSH-Px increased initially and then declined, whereas MDA levels exhibited a continuous increase. Transcriptome profiling identified 9,825 differentially expressed genes (DEGs). KEGG enrichment analysis of DEGs indicated that immune responses and metabolic regulation were consistently involved throughout the thermal adaptation process. During acute warming phase, pathways such as protein processing in the endoplasmic reticulum, FoxO signaling pathway and glycerophospholipid metabolism were enriched. Under prolonged high temperature exposure, cytokine-cytokine receptor interaction, PPAR signaling pathway and TGF-\u03b2 signaling pathway were prominently enriched. Within these pathways, genes including grp94, hsp70, bip, nef, il-1r, tlr8, cctg\u03b16, ccr4, cxcr3, and il-10 were significantly up-regulated (p\u2009<\u20090.05). These results indicate that PF-carp exhibit coordinated brain physiological and transcriptomic responses to high temperature exposure, involving protein quality control, immune signaling, and metabolic regulation. Collectively, our findings provide new insights into the mechanisms by which PF-carp adapt to thermal exposure and provide theoretical support for the breeding of heat tolerant fish.\n\nID: 42362484\nTitle: Neuropathological and Molecular Features Associated With a Heterozygous DNAJC7 Mutation in Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder with unclear molecular mechanisms. Heterozygous protein-truncating variants of DNAJC7, which encode a cochaperone involved in Hsp70/90-mediated protein quality control, are potential risk factors for ALS. However, the neuropathological consequences of heterozygous DNAJC7 mutations are unclear. We aimed to clarify the molecular and neuropathological features associated with a heterozygous DNAJC7 mutation in ALS. We genetically screened 39 Japanese patients with ALS and identified a novel heterozygous frameshift mutation in DNAJC7 (c.157_163del, p.Lys53Ter) in one patient that was neuropathologically diagnosed with Kii ALS. We performed biochemical and neuropathological analyses using postmortem tissues from this patient, from cases of ALS without the mutation and from control cases. In the cases of ALS without DNAJC7 mutation, there was elevation of both DNAJC7 mRNA and protein levels compared with controls. The patient with DNAJC7 mutation showed relatively lower DNAJC7 mRNA and protein levels compared with the nonmutated cases of ALS, although mRNA expression remained relatively higher. DNAJC7 may be upregulated as a protective response against ALS pathogenesis, whereas a heterozygous mutation may attenuate this response. Immunohistochemistry and double immunofluorescence demonstrated partial colocalization of DNAJC7 with phospho-TDP-43-positive neuronal cytoplasmic inclusions, which supports a direct role for DNAJC7 in modulating pathological TDP-43 aggregation. These findings provide neuropathological evidence linking heterozygous DNAJC7 mutation to ALS, demonstrating impaired protein expression and suggesting a loss-of-function mechanism that compromises protective responses to TDP-43 pathology. DNAJC7 may represent a key modulator of ALS pathogenesis and potential therapeutic target.\n\nID: 42325197\nTitle: Small bites for big problems: stepwise aggregate degradation by autophagy.\nAbstract: Protein aggregates are a pathological hallmark of diverse disorders, including many neurodegenerative diseases, but also cardiometabolic disease and cancer. While the ubiquitin-proteasome system efficiently removes many soluble misfolded proteins, large or persistent assemblies often require the autophagy-lysosome pathway for their degradation. In the present mini-review, we summarize our knowledge of aggrephagy, the selective clearance of protein aggregates by autophagy, and discuss two recent manuscripts that argue that some aggregates must be primed for autophagosomal degradation, through chaperone-mediated remodeling. Aggrephagy substrates are defined by aggregate architecture, biophysical state, surface accessibility, and the physical constraints of membrane capture. These features help to explain why recruitment of selective autophagy receptors is necessary yet insufficient for clearance. Receptor clustering is required to concentrate early autophagy factors to establish initiation hubs, but successful degradation often requires upstream generation of smaller 'aggrephagy-competent' cargo units, which contain autophagy receptor clusters that successfully initiate autophagosome formation. Recent work supports a model in which larger aggregates are cleared through stepwise degradation enabled by prior remodeling steps that involve p97/VCP-driven disintegration or a chaperone module (DNAJB6-HSP70-HSP110) cooperating with the proteasomal 19S regulatory particle.\n\nID: 42321214\nTitle: FKBP8 connects the Hsp70-Hsp90 chaperone machinery to the folding of membrane proteins.\nAbstract: The folding of membrane protein cytoplasmic domains on the endoplasmic reticulum (ER) surface, and their coordination with transmembrane and exoplasmic regions, remains poorly understood. Through a genome-wide CRISPR-Cas9 screen, we identified the ER-anchored FK506 binding protein 8 (FKBP8) as a chaperone essential for membrane protein folding and assembly. Using ABC transporters as model substrates, we show that FKBP8 cooperates with Hsp70-Hsp90 machinery to remodel nascent or misfolded cytosolic domains into their native conformations. Cryo-EM analysis reveals that FKBP8 employs a conserved hydrophobic \u03d594\u03d596\u03d597/\u03d5158\u03d5162 cluster to help form a large client-binding cavity within the FKBP8-Hsp90 complex that captures folding intermediates. FKBP8 deficiency, disruption of this cluster, or disease-associated mutations within FKBP8 abolish substrate maturation, leading to ER retention and degradation. Reconstitution with purified components demonstrates that FKBP8 and Hsp40-Hsp70-HOP-Hsp90 constitute a minimal machinery capable of restoring the native structure of a misfolded ABC transporter. These findings uncover a dedicated folding module at the ER-cytosol interface that bridges cytosolic chaperones with membrane protein quality control, suggesting a broad role for FKBP8 in safeguarding the biogenesis of complex membrane proteins.\n\nID: 42240479\nTitle: Molecular Chaperone Networks in Plants: Maintaining Proteostasis and Enhancing Stress Resilience for Crop Improvement.\nAbstract: Molecular chaperones play a central role in the plant proteostasis machinery by aiding the folding of nascent proteins, preventing aggregation, and repairing or degrading damaged proteins. These functions are especially essential during abiotic and biotic stress, which can destabilise cellular proteins and disrupt metabolic homoeostasis. This review summarises the current progress regarding the major heat shock protein (Hsp) families, Hsp100, Hsp90, Hsp70, Hsp60, and small heat shock proteins (sHSPs) and their key co-chaperones, DnaJ/Hsp40 and nucleotide exchange factors (NEFs), in relation to their structural characteristics, subcellular targeting, and heat shock factor (HSF)-mediated regulatory pathways. We emphasise certain examples, such as the role of Hsp101 in acquired thermotolerance or the use of sHsps as ATP-independent aggregation preventers. Transcriptional, proteomic, and interactomic analyses have shown changes in chaperone abundance and activity during stress, but there is a major gap in the understanding of how chaperone networks respond to combined, field-relevant stress. Recent biotechnological uses, such as CRISPR/CAS9-based knockout of OsHSBP1 in rice and transgenic overexpression of TaHSP17.4 in wheat, show concrete support of stress tolerance and stability in yield. Combining biochemical processes with the emerging biotechnological understanding, this review highlights how the manipulation of chaperone networks can be targeted to enhance the pace at which crops, capable of withstanding climate change, can be developed, and assist in supporting the sustainable productivity of agriculture.\n\nID: 42178287\nTitle: Sti1 participates in the dynamics of protein aggregation triggered by glucose signaling in Saccharomyces cerevisiae.\nAbstract: Environmental changes put stress on living organisms. We find that nutrient starvation induces dynamic protein aggregations in yeast cells, and many chaperones are involved in this process. Among them, Sti1/HOP, the co-chaperone of Hsp70 and Hsp90, plays roles in the formation of protein quality control (PQC) compartments and protein stasis (or proteostasis) maintenance, and it co-localizes to insoluble protein deposits (IPOD) by liquid-liquid phase separation (LLPS). Notably, the subcellular localization and cytoplasmic aggregation of Sti1 are rigorously regulated by the PQC machinery, including Ssa1/Hsp70 and Hsp82/Hsp90. On the other hand, STI1 deletion abolishes cytoplasmic aggregation of chaperones, including Ssa1, Hsp42 and Hsp104. These results reveal an interdependent model of chaperone-mediated aggregate formation. Furthermore, lysine 9 (K9) of Sti1 is identified as a critical residue governing its cytoplasmic condensation through a potential post-translational modification.\n\nID: 42137292\nTitle: Autophagy activation via BAG3 gene therapy improves phenotype in a mouse model of LGMD1A.\nAbstract: Myofibrillar myopathies (MFMs) are a group of protein aggregate diseases characterized by abnormal protein aggregations and myofibrillar disintegration. Myotilinopathy, also named MFM3 or limb-girdle muscular dystrophy type 1A (LGMD1A), is caused by myotilin mutations. Myotilin is degraded by the ubiquitin-proteasome system; however, when this pathway is overloaded under pathophysiological conditions, the protein quality control system leans on the autophagy-lysosome pathway (ALP) to mediate degradation of aggregates. BCL2-associated athanogene 3 (BAG3) protein facilitates aggresome formation and initiates ALP. In this study, we assessed our strategy of reducing the aggregate burden in muscle by overexpressing human BAG3 in TgT57I mice, a model for LGMD1A. Overexpression was achieved by systemic delivery of AAVrh74.tMCK.hBAG3, and outcome measures included functional, histological, and molecular studies. The hBAG3-treated cohort demonstrated increased rotarod duration, treadmill running distance, grip strength, and maximum tetanic response compared to the untreated cohort. Myotilin aggregate burden was significantly decreased, and autophagy levels were normalized in the treated group. As an adaptive response, hBAG3 normalized the endogenous Bag1/Bag3 ratio to that of 3-month-old TgT57I mice. This study provides evidence that our strategy of reducing the aggregate burden in muscle by overexpressing BAG3 may be used as a treatment for protein aggregate myopathies.\n\nID: 42109524\nTitle: Recent insights into HSP70: proteostasis and beyond.\nAbstract: Since the 1980s, 70 kDa heat shock proteins (HSP70s) have been recognized as central regulators of proteostasis, with diverse roles in cellular physiology and pathology. Recent research has significantly expanded our understanding of these molecular chaperones, revealing functions that extend beyond their classical roles in proteostasis. In this review, we integrate these emerging insights with foundational knowledge by outlining the biology of HSP70s, with particular emphasis on recent discoveries, such as new data on the substrate specificity and molecular dynamics of HSP70-client interactions. In addition, increasing evidence highlights their noncanonical anti-inflammatory properties, as well as other nonimmune functions, including the promotion of adipose tissue browning and the enhancement of angiogenesis through extracellular HSP70 activity. Finally, although HSP70s have long been known to regulate mRNA degradation in a transcript-specific manner, new findings demonstrate their ability to bind double-stranded RNA, further broadening their functional repertoire.\n\nID: 42097046\nTitle: BAG3V468M impairs proteasomal protein clearance and induces dilated cardiomyopathy in vivo.\nAbstract: Idiopathic dilated cardiomyopathy (DCM) is one of the major causes of heart failure, characterized by left ventricular dilation and systolic dysfunction in the absence of an identifiable cause, and is associated with reduced life expectancy. Genetic studies, including genome-wide association studies, have identified variants in BAG3, a key regulator of protein quality control (PQC), as contributors to both familial and sporadic forms of DCM. Impaired PQC and the accumulation of misfolded proteins (proteinopathy) have emerged as potential pathogenic mechanisms. Here, we investigated the molecular consequences of a recently identified BAG3 missense variant (V468\u202fM) associated with familial DCM. To assess the in vivo effects of the variant, human BAG3V468M was ectopically expressed in wild-type zebrafish embryos. Overexpression of BAG3V468M resulted in a DCM-like phenotype characterized by ventricular dilation, reduced heart rate, and impaired contractility. Transmission electron microscopy revealed marked disruption of myocardial ultrastructure and sarcomeric organization. To explore the impact on proteostasis, markers of autophagy (LC3-I/II and p62) were analyzed and showed no significant differences between BAG3V468M and control embryos under basal conditions. In contrast, analysis of the ubiquitin-proteasome system demonstrated a significant accumulation of ubiquitinated proteins in BAG3V468M-expressing embryos, suggesting impaired proteasomal protein clearance or increased proteotoxic stress. Expression of BAG3V468M induces a DCM-like phenotype in vivo associated with disrupted myocardial architecture and altered proteostasis. While canonical autophagy markers remain unchanged, the accumulation of ubiquitinated proteins points toward a disturbance in ubiquitin-mediated protein turnover. These findings implicate mutation-specific alterations in proteostasis as a potential mechanism contributing to BAG3-associated cardiomyopathy.\n\nID: 41991160\nTitle: Dosage compensation of Caj1-induced cytotoxicity by Sis1 and Ydj1 reveals complex interactions among JDPs in the yeast cytosol.\nAbstract: Cellular proteostasis depends on tightly regulated Hsp70-J-domain protein (JDP) networks that coordinate protein folding and degradation. Here, we define a previously unrecognized role for the budding yeast JDP Caj1 in modulating nucleocytoplasmic protein quality control. We show that elevated Caj1 levels broadly disrupt proteostasis, stabilizing diverse misfolded substrates by impairing their degradation and triggering the accumulation of ubiquitinated proteins, along with constitutive activation of the heat shock response (HSR). Caj1-induced defects were associated with the accumulation of ubiquitinated proteins. They were genetically suppressed by loss of the E3 ubiquitin ligases and enhanced by loss of deubiquitinating enzymes, revealing functional coupling between Caj1 activity and ubiquitin-mediated protein turnover. Co-overexpression of the major nucleocytoplasmic JDPs Ydj1 and Sis1 suppressed Caj1 toxicity, with Sis1 acting through a J-domain-dependent, Hsp104-independent mechanism. Our findings uncover a dosage-sensitive regulatory interplay among JDPs and demonstrate that relative JDP abundance, rather than absolute levels, is a critical determinant of proteostasis capacity, revealing a previously unrecognized functional network linking Caj1, Sis1, and Ydj1 in shaping cellular protein quality control.\n\nID: 41944287\nTitle: The AUTACE That Degrades KRAS and Engages CD8+ T Cells for the Treatment of KRAS/TP53 Co-Mutant Tumors.\nAbstract: KRAS and TP53 co-mutations are frequently associated with highly aggressive, therapy-resistant cancers with limited treatment options. In this study, we have developed Autophagy-Targeting Chimera-T-cell Engager (AUTACE), a bifunctional nanoplatform composed of T-cell receptor-engineered T (TCR-T) cell-derived nanovesicles that display anti-CD3 antibodies and encapsulate perfluoropentane (PFP) together with KPY, an autophagy-targeting degrader active against mutant KRAS, for the treatment of KRAS/TP53 co-mutant tumors. AUTACE targets tumors via TP53-specific TCRs, elicits antitumor CD8+ T-cell responses through surface anti-CD3 antibodies, and employs low-intensity focused ultrasound (LIFU) to trigger controlled release of KPY to degrade mutant KRAS. This achieved targeted tumor elimination. The therapeutic efficacy of AUTACE was validated in mice bearing PANC-1 and MIA PaCa-2 tumors. A comprehensive assessment of the post-treatment tumor microenvironment revealed that KRAS degradation increased tumor-derived CCL5 levels, thereby promoting CD8+ T-cell recruitment and amplifying antitumor responses. Thus, AUTACE represents a promising strategy for the treatment of KRAS/TP53 co-mutant tumors.\n\nID: 41894511\nTitle: Cold atmospheric plasma-engineered nanovaccine with spatiotemporal sequential immunization reprograms antitumor immunity.\nAbstract: Cancer immunotherapy remains limited by insufficient antigen presentation and immunosuppressive tumor microenvironment. Here, we present a vaccine strategy based on cold atmospheric plasma (CAP)-engineered tumor cell-derived immune reprogramming nanovesicles (CAPTURE) that integrates spatiotemporal sequential immunization to potentiate antitumor immunity. CAPTURE is engineered from tumor cells pretreated with CAP, which up-regulates major histocompatibility complex class I expression via p62-mediated autophagy to promote full-spectrum epitope antigen presentation, and surface-functionalized anti-CD28 (\u03b1CD28) on CAPTURE provides costimulatory signals to directly activate T cells through \u03b1CD28-CD28, bypassing B7-CTLA-4-mediated T cell inhibition. Under spatiotemporal sequential immunity, CAPTURE exhibits homologous tumor targeting and lymph node accumulation, enhancing antigen presentation for CD8+ T cell activation and tumor immunogenic remodeling. In mouse models, CAPTURE achieved near-complete tumor suppression, driven by amplified cytotoxic T cell responses, increased T cell clonal diversity, and CXCR3-mediated tumor infiltration. This study presents a universal biomimetic nanovaccine strategy that can reshape both T cells' immunity and tumor cells' immunogenicity, induce broad-spectrum immune responses to overcome immune evasion, and offer unique insights and innovative technologies for precision cancer immunotherapy.\n\nID: 41833837\nTitle: Crystal structures reveal phosphorylation-dependent disruption of the heat shock protein 70-CHIP interface: A compensatory G132N variant restores binding affinity.\nAbstract: Heat shock protein 70 (HSP70) and its E3 ligase co-chaperone CHIP (STUB1) form a critical quality-control complex that directs client proteins toward folding or degradation. Phosphorylation of HSP70 at a conserved threonine in the C-terminal tail influences the fate of clients during cellular stress, yet the structural basis for this regulation remains unclear. Here, we present crystal structures of the CHIP tetratricopeptide repeat (TPR) domain bound to unphosphorylated and phosphorylated HSP70 C-terminal peptides at 1.6-1.9\u00a0\u00c5 resolution. Phosphate occupancy at Thr636 (HSPA1A numbering) causes steric clashes and electrostatic repulsion within the TPR-binding groove, decreasing affinity by more than 10-fold, as shown by biolayer interferometry and fluorescence polarization. Molecular dynamics simulations confirm destabilization of key hydrogen bonds. A structure-guided G132N substitution in CHIP introduces new hydrogen bonds to the phosphate group, restoring affinity for phosphorylated peptides in isolated TPR domains without losing native ubiquitination activity. However, in full-length CHIP, interface modifications do not restore phosphorylation-impaired stable binding but yield only partial recovery of transient interactions in cells, indicating additional context-dependent constraints on HSP70-CHIP regulation. These findings reveal the atomic mechanism by which phosphorylation impairs HSP70-CHIP interaction during stress and demonstrate that targeted interface engineering can compensate for post-translational changes in isolated domains. Overall, the results explain how cells switch chaperone-mediated triage pathways and offer a framework for understanding how proteostasis becomes dysregulated in neurodegenerative diseases and cancer.\n\nID: 41792745\nTitle: Natural panax notoginseng-derived nanovesicles trigger multiple cell death mechanisms and reprogram chemokine signaling to impede oral squamous cell carcinoma progression.\nAbstract: Oral squamous cell carcinoma (OSCC) remains one of the most aggressive malignancies of the oral epithelium, with limited therapeutic options effectively targeting both tumor growth and metastasis. Plant-derived nanovesicles have emerged as natural, biocompatible nanomedicines with potential applications in cancer therapy. Here, we systematically screened nanovesicles from ten medicinal plants and identified Panax notoginseng-derived nanovesicles (PnNVs) as the most potent inhibitors of OSCC. PnNVs exhibited favorable safety profiles and intrinsic tumor-homing ability, selectively accumulating in orthotopic tongue tumors. In vivo, they markedly suppressed primary tumor growth and lymphatic metastasis. Mechanistically, PnNVs disrupted redox homeostasis by inhibiting the p38-MAPK/NRF2 signaling pathway, thereby inducing ferroptosis, autophagy, and PANoptosis. In addition, PnNVs impaired cancer cell migration by modulating chemokine-associated signaling pathways critical for tumor dissemination. Multi-omic analyses further revealed synergistic contributions of RNA cargos and metabolite components to their multi-target anticancer efficacy. Collectively, our findings establish PnNVs as a natural, multifunctional therapeutic candidate with dual anti-proliferative and anti-metastatic activity, providing a promising preclinical strategy for OSCC treatment.\n\nID: 41763428\nTitle: Aedes aegypti Hsp70 has enhanced ATPase and protein protection under oxidative stress.\nAbstract: Aedes aegypti mosquitoes are responsible for transmitting several viral diseases in humans, including Dengue, Zika, Yellow Fever, and Chikungunya. Despite significant efforts to control the mosquito vector and the viruses, the issue has intensified. This is mainly due to the mosquito's successful adaptation to urban environments and its expanding geographic range, driven by rising global temperatures. To effectively combat vector-borne diseases, we need a comprehensive understanding of mosquito physiology and cellular regulatory mechanisms, as these could reveal new molecular targets for intervention. A major cellular threat is environmental stress, which can cause protein misfolding and aggregation, ultimately leading to cell death. To counteract this, cells utilize their Protein Quality Control (PQC) system to maintain proteostasis. A central component of this system is the Hsp70 chaperone family, which is crucial for nascent protein folding, translocation across membranes, refolding of aggregated proteins, targeting proteins for degradation, and providing general stress protection. In this context, we identified, cloned, expressed, and characterized a cytosolic Hsp70 homolog from Aedes aegypti, which we named AaHsp70. The recombinant AaHsp70 protein was obtained in a pure and folded form, functioning as a monomer in solution and exhibiting hallmark features of the Hsp70 family, including ATPase activity and chaperone function. Notably, its ATPase activity was 2.5 to 3.3 times higher than that of human Hsp70s and increased by 90% under oxidative conditions. Furthermore, AaHsp70 successfully protected several proteins from aggregation under redox stress in Aedes larval cell extracts. Among the protected proteins was actin, a crucial cytoskeletal and contractile protein involved in both larval and adult muscle function in insects. Overall, our findings demonstrate that AaHsp70 plays a vital role in maintaining protein homeostasis under stress in mosquito cells. This chaperone may represent a promising molecular target for developing novel strategies to mitigate the spread of Aedes aegypti and the diseases it transmits.\n\nID: 41737780\nTitle: Mitofusin MFN2 acts as a molecular sensor preventing protein aggregation and mitophagy, with a protective effect against apoptosis in Charcot-Marie-Tooth type 2A disease.\nAbstract: Mitochondria are central hubs for cellular fitness, empowered by plastic remodeling of their shape, proteome composition, and/or metabolic state. MFN2 (mitofusin 2) mediates mitochondrial fusion and ensures adaptations in response to metabolic changes and stresses. Besides this canonical role, MFN2 serves as a communication hub with other organelles. It tethers mitochondria to the endoplasmic reticulum (ER), lipid droplets, and peroxisomes, regulating calcium buffering, apoptosis, lipid biosynthesis, and lipolysis. Dysfunctional MFN2 causes the hereditary neuropathy Charcot-Marie-Tooth type 2A (CMT2A) and is linked to several metabolic diseases. In a recent publication, we described another fusion-independent role of MFN2 in proteostasis and mitophagy. MFN2 binds the chaperone HSPA8/HSC70 (heat shock protein family A [Hsp70] member 8) and the proteasome, a key function in maintaining mitochondrial and cellular protein quality control, which appears to be lost in the context of CMT2A-associated MFN2 variants.\n\nID: 41683782\nTitle: Atorvastatin Protects Against Deleterious Carfilzomib-Induced Transcriptional Changes in Human Induced Pluripotent Stem Cell-Derived Cardiomyocytes.\nAbstract: The mechanisms underlying carfilzomib (CFZ)-induced cardiotoxicity remain incompletely elucidated. In this study, we used human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) to characterize the transcriptional impact of CFZ and to evaluate whether atorvastatin could prevent these deleterious transcriptional changes. hiPSC-CMs were treated with 1 \u00b5M CFZ, CFZ + atorvastatin, atorvastatin, or vehicle control, followed by RNA sequencing, differential expression analyses, and pathway analyses. Transcriptomic profiling revealed a marked upregulation of genes in multiple proteasome subunits, including ATPase components (PSMC1, PSMC4, PSMC5, PSMC6) and non-ATPase regulatory subunits (PSMD1, PSMD2, PSMD12), suggesting a strong compensatory activation of proteostasis and protein quality-control pathways in response to CFZ exposure. In addition, several of the most significantly altered genes were those implicated in cardiomyopathy and heart failure, such as BAG3 and FLNC, and many heat-shock proteins, indicating the activation of cardiac stress-response pathways relevant to CFZ-associated cardiotoxicity. Atorvastatin co-treatment partially reversed a subset of CFZ-induced transcriptional changes, particularly within cholesterol biosynthesis and lipid-regulatory pathways (e.g., ACAT2 and ACTA1) but did not restore the CFZ-mediated downregulation of sarcomeric genes. Together, these findings define a multifactorial signature of deleterious CFZ-induced transcriptional changes and suggest that atorvastatin may provide partial metabolic, but not structural, cardio protection.\n\nID: 41628755\nTitle: The 13th International Symposium on Heat Shock Proteins in Biology, Medicine, and the Environment: Honoring legacy, celebrating scientific advances, and fostering collaboration.\nAbstract: The 13th International Symposium on Heat Shock Proteins in Biology, Medicine and the Environment, organized by the Cell Stress Society International (CSSI), was held in October 2025 in Syracuse, NY, and brought together investigators spanning basic,\u00a0translational, and clinical stress biology. The meeting highlighted the continued evolution of the heat shock response from a canonical transcriptional program to a complex, multi-layered network integrating transcriptional condensates, posttranslational regulation of chaperones, spatial organization, and system-level stress adaptation. Scientific sessions showcased advances in stress-induced transcription and genome control, the expanding Hsp90/Hsp70 \"chaperone code,\" proteostasis and protein quality control, mitochondrial chaperones and metabolic regulation, cancer-immune interfaces, host-pathogen interactions, and the roles of chaperones in aging and neurodegenerative disease. Particular emphasis was placed on emerging therapeutic and diagnostic strategies, including isoform-specific chaperone inhibitors, co-chaperone targeting, theranostic approaches, and clinical-stage candidates. Systems-level analyses of stress resilience, extracellular chaperone signaling, and organismal adaptation further underscored the breadth of stress biology across scales. The symposium also honored the legacy of Dr\u00a0Len Neckers, whose pioneering contributions to Hsp90 biology shaped the field, and recognized outstanding scientific achievements through CSSI awards and fellowships. Collectively, the work presented reflects a field that continues to deepen mechanistic understanding while advancing toward precision-based therapeutic and diagnostic applications. This meeting report summarizes these developments and highlights future directions for stress biology research.\n\nID: 41611432\nTitle: ROS-responsive oligochitosan-derived nanovesicles with synergistic oxidative stress and autophagy inhibition for potent tumor therapy.\nAbstract: Oxidative stress-mediated tumor therapy leverages reactive oxygen species (ROS) for cancer treatment, but protective autophagy, a major survival pathway for tumor cells, causes therapy resistance. Herein, a self-amplifying ROS-responsive nanovesicle system (CQ/Cu@CT) is designed to enhance oxidative stress while blocking autophagy. Firstly, amphiphilic oligochitosan derivative COS-PEG2KTA-UB is synthesized, where ROS-responsive thioketal acetal (TA) is introduced in form of cinnamaldehyde (CA) prodrug. This polymer self-assembles into nanovesicles, integrating chloroquine (CQ) and supplemental TA to immobilize Cu2+ via carboxylic coordination. Intracellular ROS triggers nanovesicle dissociation to release CA, Cu2+, and CQ. CA induces mitochondrial dysfunction and ROS burst, while Cu2+ depletes glutathione and generates Cu+ for Fenton-like reactions to produce hydroxyl radicals. Meanwhile, due to the inhibition effect of CQ on protective autophagy, CQ/Cu@CT produces significantly high ROS level. The amplified ROS not only aggravates oxidative stress but also accelerates drug release from nanovesicles, which facilitates the drug action against tumors. CQ/Cu@CT also induces immunogenic cell death (ICD) to stimulate dendritic cell maturation and enhance cytotoxic T lymphocyte infiltration. Consequently, CQ/Cu@CT inhibits tumor growth by 67.8\u00a0% in a subcutaneous 4\u00a0T1 tumor model. This study provides a potent strategy to enhance oxidative stress-based cancer therapy.\n\nID: 41609899\nTitle: Stress-specific expression of HSPA and DNAJ chaperones regulated by NRF2/HSF1 in neurodegenerative conditions.\nAbstract: The cellular protein quality control and protein homeostasis is maintained by molecular chaperones that are upregulated in response to various environmental, chemical, thermal and genetic stress factors. Altered protein homeostasis owing to stress conditions lead to the accumulation of misfolded and aggregated protein conformers, a hallmark feature of several neurodegenerative and metabolic diseases. However, the effect of different stress conditions on the expression of molecular chaperones remains poorly understood. In the present study, comparative expression profile of the HSPA and DNAJ chaperone family has been analysed under oxidative stress induced by rotenone, proteotoxic stress induced by \u03b1-synuclein seeds, proteasome inhibitor and heat stress conditions. A dynamic and stress-selective expression of molecular chaperones was observed at both the gene and protein levels, where HSPA1 (HSP70), HSPA5 and DNAJB1 proteins were upregulated across all stress conditions, while HSPA8 (HSC70), HSPH1 (HSP110), DNAJB6 and DNAJB8 proteins exhibited stress-dependent unique expression patterns. The selective expression of molecular chaperones regulated through the NRF2/HSF1 axis suggests the involvement of the KEAP1/NRF2/ARE pathway in coordinating stress-dependent chaperone expression and ensuring proteome integrity. This comparative stress-specific expression profiling enables targeting of molecular chaperones to mitigate protein misfolding and aggregation, facilitating therapeutic interventions in neurodegenerative diseases.\n\nID: 41601171\nTitle: Depletion of BIS in astrocytes aggravates reactive gliosis following photothrombotic brain injury.\nAbstract: BIS (Bcl-2-interacting cell death suppressor, or BAG-3), is a multifunctional co-chaperone that maintains protein quality control via autophagy and proteostasis. Following the central nervous system (CNS) injury, BIS expression is markedly upregulated in reactive astrocytes, suggesting a regulatory role of reactive astrogliosis. To investigate this, we generated astrocyte-specific BIS knockout (BIS-aKO) mice for the first time. While BIS-aKO mice exhibited normal growth and survival, the injury-induced upregulation of BIS expression was abolished in reactive astrocytes following excitotoxic injury. Using a photothrombotic stroke model, we found that astrocytic BIS deficiency resulted in significantly increased GFAP expression in scar-forming astrocytes at the infarct border and altered morphology in the peri-infarct region. Furthermore, we observed increased infiltration of amoeboid Iba1-positive cells in the astroglial scar, indicating enhanced neuroinflammation. Correlative light-and electron-microscopy following both stroke and stab wound injury revealed BIS-aKO astrocytes exhibited a greater density of intermediate filament filling in their soma and processes, along with relatively fewer cytoplasmic organelles, such as mitochondria. Collectively, these findings highlight a previously unrecognized role of BIS in modulating reactive gliosis during brain injury and our model provides a valuable tool for investigating the astrocyte-specific functions of BIS in CNS pathophysiology.\n\nID: 41497405\nTitle: Hydrophobic tagging: A promising paradigm for targeted protein degradation.\nAbstract: Targeted protein degradation (TPD) has emerged as a groundbreaking therapeutic strategy, overcoming the limitations of traditional occupancy-driven pharmacology. Among TPD strategies, hydrophobic tag (HyT) technology exemplifies this paradigm shift by hijacking cellular protein quality control mechanisms for precise protein elimination. Structurally, HyT molecules integrate a target-specific ligand with a hydrophobic domain that emulates misfolded protein surfaces, facilitating selective recruitment of chaperone systems (e.g., heat shock protein 70, HSP70) and ubiquitin-proteasome system (UPS) activation, circumventing the E3 ligase dependency inherent to proteolysis-targeting chimera (PROTAC) systems. This innovative strategy offers distinct therapeutic benefits, including enhanced tissue-specific accumulation and the capacity to overcome resistance mechanisms. This review highlights the important advances in this rapidly growing field and critical limitations encountered in developing HyT degraders by analyzing the current status and representative examples of HyTs in degrading diverse pathogenic proteins, including oncogenic drivers (e.g., signal transducer and activator of transcription 3, STAT3), neurodegenerative aggregates (tau, \u03b1-synuclein), and viral envelope proteins. The critical developments, including the rational design of hydrophobic motifs and possible mechanistic insight into the degradation process of HyTs, have also been discussed.\n\nID: 41416371\nTitle: Stress-specific NONO interactomes reveal a key role of Hsp70 chaperone activity in regulation of paraspeckle formation.\nAbstract: Paraspeckles are stress-induced nuclear RNA-protein condensates that assemble on the long non-coding RNA NEAT1. Their increased formation under certain cellular circumstances has gained growing interest due to their association with serious human diseases, such as neurodegenerative disorders and cancer. The biological functions of paraspeckles still appear obscure, but increasing evidence suggests that they contribute to regulation of gene expression by recruiting specific proteins and RNA molecules. Here, we have characterized and compared two stress-enriched interactomes of the essential paraspeckle protein NONO in both wild-type and paraspeckle-deficient NEAT1 knockout cells. We identified Hsp70 as part of stress-enriched NONO complexes in wild-type but not in NEAT1-depleted cells. We show that proteotoxic stress-induced paraspeckle formation and NEAT1 expression are strictly dependent on Hsp70 chaperone activity. Our data demonstrate that both NONO and Hsp70 transiently translocate to the nucleolus during heat shock and that paraspeckle formation during recovery follows Hsp70-dependent relocation of NONO from the nucleolus to the nucleoplasm. Taken together, we demonstrate an important role of Hsp70 in paraspeckle assembly and identify a possible link between the nuclear protein quality control system and paraspeckles.\n\nID: 41247156\nTitle: Mesenchymal stem cell-derived nanovesicles coated PLGA nanoparticle (MSC-PLGA-NPs) remodel lysosomal function to clear pathological proteins in Alzheimer's disease models.\nAbstract: To develop a novel multifunctional nanoparticle platform by combining mesenchymal stem cell-derived nanovesicles (MSC-NVs) with poly(lactic-coglycolic acid) (PLGA) nanoparticles for Alzheimer's disease (AD) therapy. Mesenchymal stem cell-derived nanovesicle-poly(lactic-coglycolic acid) nanoparticles (MSC-PLGA-NPs) were prepared via sonication-loading. Blood-brain barrier (BBB) penetration was evaluated using in vitro transwell models and in vivo mouse models. Lysosomal function, autophagy, pathological protein clearance, and anti-inflammatory effects were assessed using various cellular and molecular biology techniques. MSC-PLGA-NPs demonstrated 2.3-fold higher BBB penetration efficiency compared to PLGA alone. In a chloroquine(CQ)-induced lysosomal injury model and mice model, they effectively restored lysosomal pH, enhanced autophagy (reducing LC3-II/I ratio by 0.4-fold and p62 expression by 52%), cleared amyloid precursor protein (APP) and phosphorylated tau (p-tau) proteins, and inhibited IL-6 and TNF-\u03b1 without hepatorenal toxicity. These results demonstrate that MSC-PLGA-NPs, a novel multifunctional nanoparticle platform, synergistically integrates the BBB penetration capability of MSC-NVs and the lysosomal acidification function of PLGA. The synergistic combination represents a pioneering \"delivery-repair-clearance\" integrated strategy for AD therapy. Offering significant advantages over single-component approaches, MSC-PLGA-NPs provide a promising preclinical candidate and new insight into lysosome-targeted nanomedicines for neurodegenerative diseases.\n\nID: 41184271\nTitle: Microglia-derived nanovesicles synchronize macroautophagy and chaperone-mediated autophagy for Alzheimer's disease therapy.\nAbstract: Dysregulated autophagy is a hallmark of Alzheimer's disease (AD), yet the extent of impairment in macroautophagy and chaperone-mediated autophagy (CMA) remains unclear. Here, we show that both pathways are disrupted in AD model mice, preceding \u03b2-amyloid accumulation and driving disease progression. However, therapeutic autophagy modulation is severely restricted by the blood-brain barrier (BBB). To overcome this, we developed Microglia-Liposome Fusion Extrusion (MiLi-FE), a method to engineer microglia-derived nanovesicles (AR@ENV) for the codelivery of AR7 (a CMA inducer) and rapamycin (a macroautophagy inducer). Leveraging its microglial membrane origin, AR@ENV effectively crosses the BBB and targets inflammatory sites in the AD brain, where it is internalized by neurons. Once inside, they synchronously activate both autophagy pathways: AR7 antagonizes retinoic acid receptor alpha (RAR\u03b1) to enhance CMA, while rapamycin inhibits mTOR to promote macroautophagy. This coordinated activation enhances clearance of \u03b2-amyloid and other toxic aggregates, restores proteostasis, and provides robust neuroprotection. Furthermore, the strategy ameliorates neuroinflammation and significantly rescues cognitive deficits in two distinct AD mouse models. By integrating synchronized dual autophagy activation with targeted biomimetic delivery, AR@ENV represents a promising therapeutic candidate for AD. Moreover, the MiLi-FE platform offers a versatile and scalable approach for delivering diverse therapeutics to the central nervous system, extending its potential applicability to a range of neurological disorders.\n\nID: 41145833\nTitle: Mechanisms and regulation of the Hsp70 chaperone network.\nAbstract: The 70-kDa heat shock protein (Hsp70) chaperone is essential to maintain cellular protein homeostasis, facilitating the folding, assembly, membrane translocation and quality control of proteins. Hsp70s achieve their functions through 'selective promiscuity', interacting with a wide range of substrate proteins while minimizing undesired interactions. J-domain proteins (JDPs) and nucleotide exchange factors (NEFs) are key to substrate recognition, remodelling and release from chaperone complexes. JDPs either target Hsp70s to specific subcellular sites where substrates reside (recruiters) or bind substrates directly by using highly specific (specialists) or multiple, versatile (generalists) binding sites. Through diverse substrate-binding modes and regulatory mechanisms, the 50 human JDPs confer remarkable client specificity to Hsp70s, a function that is comparable to that achieved by close to 600 E3 ubiquitin ligases in targeting proteins for degradation. Moreover, JDPs, together with NEFs, dictate the fate of Hsp70 clients by directing them to distinct protein quality control pathways, resulting in their folding or degradation. These recent mechanistic insights into Hsp70 regulation not only highlight the versatility and complexity of the Hsp70 network but also offer new avenues for more specific interventions in ageing-related and other protein folding diseases.\n\nID: 41053261\nTitle: Structural polymorphism of \u03b1-synuclein fibrils alters the pathway of Hsc70-mediated disaggregation.\nAbstract: Pathological aggregation of \u03b1-synuclein into amyloid fibrils is a hallmark of synucleinopathies, including Parkinson's disease. Despite this commonality, synucleinopathies display divergent disease phenotypes that have been attributed to disease-specific three-dimensional structures of \u03b1-synuclein fibrils, each with unique toxic gain-of-function profiles. The Hsc70 chaperone is remarkable in its ability to disassemble pre-existing amyloid fibrils of different proteins in an ATP and co-chaperone-dependent manner. We find, however, using six well-defined conformational polymorphs of \u03b1-synuclein fibrils, that the activity of the Hsc70 disaggregase machinery is sensitive to differences in the amyloid conformation, confirming that fibril polymorphism directly affects interactions with the proteostasis network. Amyloid conformation influences not only how efficiently fibrils are cleared by the Hsc70 machinery but also the balance between depolymerization and fragmentation during disaggregation. We further show that, in vitro, the active processing of fibrils by the Hsc70 machinery inadvertently produces seeding competent species that further promote protein aggregation. Amyloid conformation thus is an important feature that can tilt the balance between beneficial or detrimental protein quality control activities in a disease-context.\n\nID: 41031819\nTitle: The E3 ubiquitin ligase STUB1 inhibits Senecavirus A replication by mediating VP1 ubiquitination and proteasomal degradation.\nAbstract: Senecavirus A (SVA), an emerging vesicular pathogen, poses a significant threat to the global pig industry. STIP1 homology and U-box-containing protein 1 (STUB1), a chaperone-dependent E3 ubiquitin ligase, plays a pivotal role in protein quality control by mediating target protein degradation. However, its precise role of STUB1 in regulating SVA replication remains undefined. In this study, we combined liquid chromatography-mass spectrometry, confocal imaging, and Western blotting to demonstrate that STUB1 interacts with the SVA VP1 protein and negatively regulates SVA replication. Mechanistically, STUB1 promotes the ubiquitination-dependent degradation of VP1 by specifically targeting lysine residues at positions 177 and 260 (K177 and K260). This degradation process is significantly enhanced by heat shock protein 70 (HSP70) and heat shock cognate protein 70 (HSC70), which strengthen the STUB1-VP1 interaction. Notably, the SVA 3C protease (3Cpro) counteracts this antiviral defense by enzymatically reducing STUB1 expression. In vivo studies using a mouse model showed that a VP1 mutant virus lacking STUB1-targeted ubiquitination sites replicates more efficiently than the wild-type strain, resulting in significantly higher viral loads across multiple tissues and more severe pulmonary pathology. Together, these findings reveal that STUB1 inhibits SVA replication through ubiquitination-dependent degradation of VP1, a process that is antagonized by viral 3C protease via suppression of STUB1 expression. Viruses have evolved diverse strategies to enhance their replication efficiency. Senecavirus A (SVA), an emerging porcine pathogen associated with vesicular disease outbreaks, has become increasingly prevalent in swine populations worldwide. As a chaperone-dependent E3 ubiquitin ligase, STUB1 plays a crucial role in maintaining cellular protein homeostasis. In this study, we elucidated the functional interplay between STUB1 and SVA replication. Our results demonstrate that STUB1 directly interacts with the viral protein VP1 and mediates its ubiquitination-dependent degradation through specific targeting of lysine residues at positions 177 and 260 (K177 and K260), thereby significantly inhibiting viral replication. However, SVA has evolved a countermeasure, whereby its 3C protease (3Cpro) downregulates STUB1 expression, effectively blocking VP1 degradation and subverting this host antiviral defense to promote viral propagation. These findings not only reveal novel host-virus interaction mechanisms but also provide valuable molecular targets for developing innovative strategies to control SVA infection.\n\nID: 41025326\nTitle: Nuclear and cytosolic J-domain proteins provide synergistic control of Hsf1 at distinct phases of the heat shock response.\nAbstract: The heat shock response (HSR) is the major defense mechanism against proteotoxic stress in the cytosol and nucleus of eukaryotic cells. Initiation and attenuation of the response are mediated by stress-dependent regulation of heat shock transcription factors (HSFs). Saccharomyces cerevisiae encodes a single HSF (Hsf1), facilitating the analysis of HSR regulation. Hsf1 is repressed by Hsp70 chaperones under non-stress conditions and becomes activated under proteotoxic stress, directly linking protein damage and its repair to the HSR. J-domain proteins (JDPs) are essential for targeting of Hsp70s to their substrates, yet the specific JDP(s) regulating Hsf1 and connecting protein damage to HSR activation remain unclear. Here, we show that the yeast nuclear JDP Apj1 primarily controls the attenuation phase of the HSR by promoting Hsf1's displacement from heat shock elements in target DNA. In apj1\u0394 cells, HSR attenuation is significantly impaired. Additionally, yeast cells lacking both Apj1 and the major JDP Ydj1 exhibit increased HSR activation even in non-stress conditions, indicating their distinct regulatory roles. Apj1's role in both nuclear protein quality control and Hsf1 regulation underscores its role in directly linking nuclear proteostasis to HSR regulation. Together, these findings establish the nucleus as key stress-sensing signaling hub.\n\nID: 41020413\nTitle: Hsp104-Hsp70-Hsp110 chaperones disintegrate kinase aggregates formed upon stress in Saccharomyces cerevisiae.\nAbstract: The cellular protein quality control (PQC) machinery maintains proteostasis. However, knowledge of PQC machinery-mediated handling of stress-induced misfolded proteins is still insufficient. We used the yeast kinase Ste11 to observe its fate upon heat stress or Hsp90 inhibition. We observed that while mild heat stress (37\u2009\u00b0C) primarily resulted in proteasomal degradation of Ste11, severe heat stress (42\u2009\u00b0C) resulted predominantly in aggregation. Ste11 aggregates sequestered with Hsp42 upon heat stress or Hsp90 inhibition. These aggregates associate with Hsp70 and Hsp104, the yeast disaggregase machinery. Notably, Ste11 aggregates disappear upon recovery from stress. This phenomenon is impaired in the absence of Hsp104 or Sse1, a co-chaperone recruited to the aggregates by Hsp70, suggesting the involvement of Hsp104, Hsp70 and Sse1 in aggregate mobilisation.\n\nID: 40976416\nTitle: Hsp70 and Hsp90 post-translational modifications and translating the chaperone code.\nAbstract: Molecular chaperones maintain proteostasis by assisting protein folding, stability, and activity. Heat shock protein 70 (Hsp70) and Hsp90 (Hsp90) are ATP-dependent chaperones essential for protein quality control, signaling, and stress adaptation. Their activities are controlled not only by co-chaperones, but also by dynamic post-translational modifications (PTMs). This review dissects phosphorylation, acetylation, methylation, ubiquitination, glycosylation, and other PTMs of Hsp70 and Hsp90 across systems. These PTMs regulate the ATPase activity, localization, and interactions of the molecular chaperones with major implications in health and disease. The term \"chaperone code\" describes the PTM landscape that fine-tunes chaperone function. This code governs client fate, drug sensitivity, and stress responses. Importantly, combinatorial PTMs introduce regulatory complexity and flexibility, especially in cancer, neurodegeneration, and inflammation. The crosstalk between various PTMs and feedback loops add new regulatory layers to chaperone function. Additionally, these PTMs impact the function of the clients that are central in regulating specific cellular processes or pathways, such as transcription, autophagy, metabolism, and immune regulation. These pathways are usually affected in different maladies, such cancer, neurodegenerative, infectious and chronic diseases. Unlocking the chaperone code is essential for directing chaperone activity toward therapeutic benefit. This can be achieved by targeting enzymes that write, erase, or read the chaperone code, thereby offering new therapeutic strategies.\n\nID: 40868968\nTitle: A Novel Small-Molecule GRP94 Modulator Increases PCSK9 Secretion and Promotes LDLR Degradation.\nAbstract: The endoplasmic reticulum (ER) maintains protein homeostasis through chaperone-mediated folding and ER-associated degradation (ERAD). Disruption of this quality control, particularly involving the ER chaperone GRP94, contributes to diseases such as hypercholesterolemia, cancer, and immune disorders, where defective GRP94-dependent folding and the trafficking of client proteins like PCSK9, integrins, and Toll-like receptors drive pathology. Here, we characterize NSC637153 (cp153), a small molecule identified in a drGFP-based ERAD dislocation screen, as a selective probe of GRP94-dependent processes. cp153 inhibits the dislocation of ERAD substrates, preferentially affecting luminal clients, increases PCSK9 secretion, and promotes LDLR degradation. Unlike ATP-competitive HSP90 inhibitors, cp153 does not induce HSP70 or destabilize AKT, suggesting that it perturbs GRP94 function by interfering with client interaction or folding. The identification of cp153 provides a useful tool to for probing GRP94's role in protein folding, trafficking, ER quality control, and disease-relevant signaling pathways, and supports the development of client-selective GRP94-targeted therapies.\n\nID: 40866512\nTitle: A chaperone-proteasome-based fragmentation machinery is essential for aggrephagy.\nAbstract: Perturbations in protein quality control lead to the accumulation of misfolded proteins and protein aggregates, which can compromise health and lifespan. One key mechanism eliminating protein aggregates is aggrephagy, a selective type of autophagy. Here we reveal that fragmentation is required before autophagic clearance of various types of amorphous aggregates. This fragmentation requires both the 19S proteasomal regulatory particle and the DNAJB6-HSP70-HSP110 chaperone module. These two players are also essential for aggregate compaction that leads to the clustering of the selective autophagy receptors, which initiates the autophagic removal of the aggregates. We also found that the same players delay the formation of disease-associated huntingtin inclusions. This study assigns a novel function to the 19S regulatory particle and the DNAJB6-HSP70-HSP110 module, and uncovers that aggrephagy entails a piecemeal process, with relevance for proteinopathies.\n\nID: 40735705\nTitle: Topical application of Tea leaf-derived nanovesicles reduce melanogenesis by modulating the miR-828b/MYB4 axis: better permeability and therapeutic efficacy than conventional tea extracts.\nAbstract: Over-pigmentation of skin caused by excessive melanin production faces the challenges of limited therapeutic effects and safety, the conventional tea leaf extract (TET) for pigmentation treatment has the disadvantages of residual harmful substances, low penetration efficiency, here we propose the tea leaf-derived nanovesicles (TLNVs) as natural nanomaterials that combine bioactive components in tea leaves and exosome-like delivery advantages for targeting over-pigmentation treatment. This study extracted TLNVs from fresh tea leaves by ultracentrifugation and characterized them by transmission electron microscopy (TEM), nanoparticle tracking analysis (NTA) and secondary metabolites composition analysis. In vitro, TLNVs exhibited stronger radical scavenging ability and tyrosinase inhibitory effect than conventional tea leaf extract, while inhibiting B16-F10\u00a0cell proliferation and melanin synthesis. Based on these in vitro results, we further evaluated the anti-pigmentation effects of TLNVs in an uvB-induced pigmented mouse model, in which TLNVs markedly reduced epidermal melanin deposition and epidermal thickness while increasing dermal thickness and collagen volume fraction. TLNVs effectively suppressed the expression of inflammatory cytokines (TNF-\u03b1 and IL-1\u03b2) and promoted melanoautophagy by upregulating LC3B and downregulating P62. Moreover, confocal laser scanning microscopy (CLSM) analysis of fluorescently labeled TLNVs confirmed their penetration ability into the deep dermis, reaching approximately 200\u00a0\u03bcm. Mechanistic studies demonstrated that miR-828b in TLNVs directly targeted MYB4 via PI3K/AKT pathway and downregulated melanogenesis regulators such as MITF and TYR. to reduce melanin production. Overexpression of MYB4 reversed the inhibitory effects of miR-828b on melanogenesis, confirming the specificity of this regulatory axis. This study is the first to confirm that TLNVs, as natural nanomaterials, exert multifunctional properties in combating skin pigmentation through the miR-828b/MYB4 axis. These include antioxidation, anti-inflammation, and the promotion of autophagy activity. TLNVs with high transdermal permeability and low toxicity provide a safer strategy for coping with pigmented skin diseases and sustainable tea leaf resource utilization.\n\nID: 40734647\nTitle: Mitochondrial protein aggregates recruit key chaperones and are sequestered in a fission- and fusion-dependent process.\nAbstract: The potential proteotoxicity of mitochondrial aggregates in yeast cells is reduced by a sequestration of affected polypeptides into a mitochondrial protein quality control compartment (IMiQ). Based on the expression of an aggregation-prone protein in the mitochondrial matrix, we determined the effect of organelle dynamics on aggregate sequestration. Fusion-deficient cells were unable to accumulate the aggregates in the IMiQ, resulting in a stress-sensitive phenotype. In contrast, fission-deficient cells could not separate the aggregate from the mitochondrial network. In these mitochondria, the aggregates were neutralized by the formation of a shell formed by mitochondrial chaperones. We also performed quantitative mass spectrometry to analyse the mitochondrial proteome and the extent of co-aggregation of mitochondrial proteins. Although only minor changes of the total proteome were detected in response to aggregate accumulation, we found a recruitment of proteins of the respiratory chain complexes and of the protein quality control system (PQC). In particular, members of the Hsp70 chaperone family were prominently associated with the aggregate. We conclude that this chaperone-dependent neutralization prevents a major co-aggregation of endogenous mitochondrial proteins.\n\nID: 40672285\nTitle: Nuclear and cytosolic J-domain proteins provide synergistic control of Hsf1 at distinct phases of the heat shock response.\nAbstract: The heat shock response (HSR) is the major defense mechanism against proteotoxic stress in the cytosol and nucleus of eukaryotic cells. Initiation and attenuation of the response are mediated by stress-dependent regulation of heat shock transcription factors (HSFs). Saccharomyces cerevisiae encodes a single HSF (Hsf1), facilitating the analysis of HSR regulation. Hsf1 is repressed by Hsp70 chaperones under non-stress conditions, and becomes activated under proteotoxic stress, directly linking protein damage and its repair to the HSR. J-domain proteins (JDPs) are essential for targeting of Hsp70s to their substrates, yet the specific JDP(s) regulating Hsf1 and connecting protein damage to HSR activation remain unclear. Here we show that the yeast nuclear JDP Apj1 primarily controls the attenuation phase of the HSR by promoting Hsf1's displacement from heat shock elements in target DNA. In apj1\u0394 cells, HSR attenuation is significantly impaired. Additionally, yeast cells lacking both Apj1 and the major JDP Ydj1 exhibit increased HSR activation even in non-stress conditions, indicating their distinct regulatory roles. Apj1's role in both nuclear protein quality control and Hsf1 regulation underscores its role in directly linking nuclear proteostasis to HSR regulation. Together these findings establish the nucleus as key stress-sensing signaling hub.\n\nID: 40595600\nTitle: Reduced fungal protein acetylation mediates the antimicrobial activity of a rhizosphere bacterium against a phytopathogenic fungus.\nAbstract: Rhizosphere microbes can protect plants from phytopathogens, but the molecular mechanisms are often poorly understood. Here, we report that a rhizosphere bacterium, Bacillus amyloliquefaciens strain TG1-2 displays antimicrobial activity against various phytopathogenic fungi and oomycetes, in a process that is mediated by the NatA acetyltransferase complex in the phytopathogenic fungus Verticillium dahliae. We show that acetylation of the molecular chaperone Hsp83 by NatA facilitates the formation of a co-chaperone complex Hsp83-Sti1-Hsp70 involved in protein quality control. Dysfunction of NatA or disruption of Hsp83 acetylation results in dissociation of the co-chaperon complex, increasing protein degradation and fungal apoptosis. Notably, TG1-2 and its major antimicrobial compound surfactin induce a reduction in Hsp83 acetylation, enhancing protein degradation and fungal apoptosis. Thus, our study provides insights into the mechanisms underlying the antimicrobial action of a rhizosphere strain against phytopathogenic fungi.\n\nID: 40536193\nTitle: Co-chaperones fine-tune the function of heat shock protein 70 (Hsp70), whether to fold, hold, or degrade substrates in ensuring cellular protein homeostasis.\nAbstract: The molecular chaperone Hsp70 is a pivotal player in cellular protein quality control due to its wide range of substrates ranging from unfolded, native, to misfolded proteins. Increasing evidence suggests that Hsp70 decides the fate of proteins; however, the inherent rules that govern the decision-making capacity of Hsp70 are not clear. In this review, we have articulated the functions of Hsp70 with respect to proteostasis and established a link between its co-chaperones in deciding the fate of the substrate. The substrate binding of Hsp70 is mediated by its catalytic cycle where Hsp70 achieves high- and low-substrate-affinity ADP- and ATP-bound forms, respectively. This catalytic cycle of Hsp70 is maintained by co-chaperones J-domain proteins (JDPs), and nucleotide exchange factors (NEFs). JDPs bind to the ATP-bound form of Hsp70 and hydrolyze ATP that enhances substrate binding, whereas NEFs exchange ADP with ATP and facilitate substrate release. During evolution, several isoforms of Hsp70 and its co-chaperones have emerged which may have functional significance. Apart from facilitating the catalytic cycle of Hsp70, co-chaperones often mediate collaboration between Hsp70 and downstream protein quality-control pathways such as the ubiquitin proteasome system, autophagy, or disaggregase machinery. Therefore, co-chaperones have a significant role in Hsp70's triage decision of whether to fold, hold, or degrade.\n\nID: 40486083\nTitle: Small but mighty: ATG9A-positive vesicles are a branch of the intracellular nanovesicle superfamily.\nAbstract: The molecular and functional characterization of the thousands of uncoated intracellular transport vesicles inside cells is a major challenge. Intracellular nanovesicles (INVs) are a large and molecularly heterogenous family of uncoated transport vesicles, which are comprised of multiple subtypes. As a step to characterizing these subtypes, we recently published the first INV proteome and were intrigued by the enrichment of ATG9A in it. ATG9A is the only conserved transmembrane protein with a core function in macroautophagy/autophagy, and it is found on small, uncoated vesicles, termed \"ATG9A-positive vesicles\". We therefore, set out to disambiguate the relationship between these two types of vesicular carriers in cells. We showed that ATG9A-containing vesicles, rather than being a distinct vesicle class, represent one subset of the INV family. We also demonstrated that this relationship is functionally important and that perturbing INV-mediated trafficking impeded starvation-induced autophagy. Here, we briefly introduce INVs, summarize the evidence supporting our definition of ATG9A-flavor INVs and present our outlook on why we hope that this classification will help to consolidate efforts to understand the functions of these vesicles in autophagy and beyond.\n\nID: 42565729\nTitle: Novel Insights into the Human Hsc70 Structure by Cross-Linking Mass Spectrometry and Molecular Modeling.\nAbstract: Heat shock cognate protein 70 (Hsc70) is a 71 kDa molecular chaperone belonging to the Hsp70 family of heat shock proteins. These proteins act as ATP-dependent molecular machines that assist protein folding under both physiological and stress conditions such as hypoxia, heat shock, and pH fluctuations. In addition to general chaperone functions, Hsc70 performs specialized roles, including uncoating clathrin-coated vesicles, facilitating protein transport into organelles, and targeting proteins for lysosomal degradation. Members of the Hsp70 family are known to form dimers and higher oligomers, but the structural organization and functional relevance of these assemblies remain poorly understood. Earlier studies also suggested that J-domain proteins (JDPs) can promote Hsp70 dimerization. In this study, we used chemical cross-linking, high-resolution Fourier transform mass spectrometry (FTMS), 15N isotopic labeling, and advanced data analysis to investigate the structural organization of Hsc70 dimers. Cross-link-derived distance restraints enabled structural modeling of Hsc70 monomers and dimers using AlphaLink2. Our results reveal distinct ATP- and ADP-state dimer conformations that coexist in equilibrium. In the presence of the cochaperone DnaJB1, we observed a shift in the dimer-monomer equilibrium, accompanied by enhanced ATP hydrolysis and formation of intermediate species. These findings demonstrate that the Hsc70 dimer population is structurally heterogeneous and depends on nucleotide state and cochaperone interactions.\n\nID: 42547642\nTitle: The Dual Roles of Microglia- and Astrocyte-Derived Exosomes in Cerebral Ischemia-Reperfusion Injury: from Intercellular Communication to Therapeutic Prospects.\nAbstract: Cerebral ischemia-reperfusion injury (CIRI) is a complex pathological process characterized by metabolic dysfunction, oxidative stress, neuroinflammation, and structural and functional alterations of the neurovascular unit (NVU). Across different studies, CIRI has been reported to be associated, to varying degrees, with neuronal injury and neurological dysfunction. Increasing evidence suggests that exosomes (EXOs) derived from glial cells, particularly microglia and astrocytes, play critical roles in mediating intercellular communication and regulating injury progression in CIRI. This review systematically summarizes the context-dependent and heterogeneous functions of glia-derived EXOs in CIRI. Microglia-derived EXOs exhibit diverse and context-dependent functions depending on the activation state of donor cells and the surrounding microenvironmental conditions. Under pro-inflammatory conditions, EXOs released from microglia may exacerbate inflammation by carrying cargo components such as circular RNAs (circRNAs) and pro-inflammatory proteins, whereas EXOs associated with reparative states may support tissue recovery through the delivery of functional non-coding RNAs. These cargo components may participate in pathological regulation through multiple signaling pathways. Among them, the nuclear receptor coactivator 4 (NCOA4) axis is associated with ferroptosis, ubiquitin-specific protease 14 (USP14) with proteostasis/apoptosis, and thioredoxin-interacting protein (TXNIP) with inflammasome activity, all of which have been linked to reduced neuronal injury and functional recovery. In addition, M2-type-derived EXOs may participate in the regulation of synaptic plasticity and axonal regeneration by modulating the plexin A2 (PLXNA2)/RhoA/ROCK2 signaling pathway. Astrocyte-derived EXOs (ATC-EXOs) further contribute to NVU regulation. A2-type-derived EXOs have been reported in multiple experimental models to be associated with reduced NLR family pyrin domain containing 3 (NLRP3) inflammasome activity and alterations in the PI3K/Akt and MAPK signaling pathways, accompanied by attenuated inflammatory responses and improved blood-brain barrier (BBB) integrity in these models. Some studies suggest that these effects may be related to the transition of microglial phenotypes toward reparative states; however, sufficient in vivo mechanistic evidence supporting their direct regulatory effects remains lacking. In contrast, neurotoxic astrocytes (A1)-derived EXOs exhibit limited or context-dependent effects. Importantly, exosome function is highly state-dependent and cannot be fully explained by simplified pro-inflammatory microglia anti-inflammatory microglia (M1/M2) or A1/A2 paradigms. Moreover, extracellular vesicle heterogeneity and methodological limitations remain major challenges. Despite promising therapeutic potential, including the ability to cross the BBB and enable multi-target regulation, significant barriers to clinical translation persist, such as delivery efficiency, biodistribution, and standardization. Overall, glia-derived EXOs represent a dynamic and multi-level regulatory system in CIRI and a promising platform for precision therapeutic strategies.\n\nID: 42529830\nTitle: Targeting chaperone-mediated autophagy by nutritional interventions mitigates age-related cardiac fibrosis and diastolic dysfunction.\nAbstract: Cardiac fibrosis, a major pathological hallmark of aging that leads to heart failure, is characterized by excessive collagen deposition. Our knowledge of what sustains collagen synthesis in the aging heart is still very preliminary. Here, we uncover a central role for chaperone-mediated autophagy (CMA), a selective lysosomal degradation pathway, in this process. We demonstrate that CMA is suppressed in the aging heart, which promotes collagen overproduction in fibroblasts, whereas enhancing CMA activity ameliorates fibrosis and diastolic dysfunction. Mechanistically, we identify SHMT2 (serine hydroxymethyltransferase 2) as a CMA substrate whose accumulation with aging drives collagen synthesis by increasing glycine availability. Integrative omics revealed a systemic downregulation of the ketone body \u03b2-hydroxybutyrate (BHB) in aged mice. BHB supplementation - via a cyclic ketogenic diet - restored CMA, attenuated fibrosis, and improved cardiac function. This recovery was mediated through BHB-induced activation of the HCAR2 receptor and subsequent phosphorylation of HSPA8/HSC70, which systemically reactivates the CMA machinery. Furthermore, we show that Lycium barbarum polysaccharide (LBP) rejuvenates hepatic ketogenesis and mimics the benefits of BHB. Our findings establish a BHB-HCAR2-CMA-SHMT2 regulatory axis as a critical mechanism driving aging-related cardiac fibrosis and highlight nutritional strategies that target CMA as promising therapies against cardiac aging.Abbreviations AcAc: acetoacetic acid; BHB: \u03b2-hydroxybutyrate; CMA: chaperone-mediated autophagy; COL1: collagen type I; COL3: collagen type III; ECM: extracellular matrix; GAPDH: glyceraldehyde-3-phosphate dehydrogenase; HCAR2: hydroxycarboxylic acid receptor 2; HSPA8/HSC70: heat shock protein family A (Hsp70) member 8; HF: heart failure; HK2: hexokinase 2; IVRT: isovolumic relaxation time; KD: ketogenic diet; LAMP2A: lysosome associated membrane protein 2A; LBP:Lycium barbarumpolysaccharide; PKM/PKM2: pyruvate kinase M1/2; SHMT2: serine hydroxymethyltransferase 2; VIM: vimentin.\n\nID: 42366592\nTitle: RAPSN/rapsyn aggregation-induced HSPA/HSP70-BAG3 aggrephagy maintains CHRN integrity in myasthenia gravis.\nAbstract: Accelerated CHRN/AChR/nicotinic acetylcholine receptor internalization induced by auto-antibodies impairs neuromuscular junction transmission and contributes to myasthenia gravis (MG), a typical autoimmune disease. Although CHRN internalization is well established in MG pathogenesis, the downstream cellular events, especially those related to autophagy, remain poorly described. Here, we report that RAPSN/rapsyn, an intracellular CHRN-binding protein essential for its clustering, accumulates as aggregates in experimental autoimmune myasthenia gravis (EAMG) mice. In CHRN antibody-treated myotubes, RAPSN dissociates from internalized CHRN and forms aggregates due to exposure of its hydrophobic domains. These aggregates in turn impair the trafficking and membrane incorporation of newly synthesized CHRN, thereby exacerbating CHRN loss. Notably, the accumulation of RAPSN aggregates facilitates formation of HSPA/HSP70-BAG3 complex, which recognizes and transports the aggregates along microtubules to form perinuclear aggresomes for subsequent lysosomal degradation. Accordingly, pharmacological inhibition or knockdown of HSPA-BAG3 complex increases RAPSN aggregation, which participates in enhanced CHRN loss and worsened muscle weakness in EAMG mice. This study identifies HSPA-BAG3 aggrephagy as a protective mechanism that clears RAPSN aggregates to maintain CHRN integrity and suggests a potential therapeutic strategy for MG.Abbreviation: 3-MA: 3-methyladenine; AAV: adeno-associated virus; CASA: chaperone-assisted selective autophagy; CHRN/nicotinic acetylcholine receptor: cholinergic receptor nicotinic; CHRN-ab: CHRN antibodies; CHX: cycloheximide; CMAP: compound muscle action potential; CQ: chloroquine; EAMG: experimental autoimmune myasthenia gravis; ER: endoplasmic reticulum; GAS: gastrocnemius; MAP1LC3A/B: microtubule associated protein 1 light chain 3 alpha/beta; MG: myasthenia gravis; NMJ: neuromuscular junction; Rapa: rapamycin; RAPSN/rapsyn: receptor associated protein of the synapse; SQSTM1: sequestosome 1; TA: tibialis anterior; \u03b1BTX-A594: \u03b1-bungarotoxin-Alexa-594.\n\nID: 42274549\nTitle: Human Chorionic Gonadotropin (hCG)-Induced Remodeling of the Granulosa Cell Exosomal Proteome: Implications for Follicular Communication.\nAbstract: Human follicular development depends on coordinated communication between granulosa cells (GCs) and oocytes through endocrine cues, direct contacts, and extracellular vesicles (EVs). Exosomes are key EV mediators of intrafollicular signaling, but their cargo and functions in gonadotropin-stimulated GCs remain poorly defined. The human granulosa-like tumor cell line KGN was used to investigate exosome secretion and protein composition following human chorionic gonadotropin (hCG) stimulation. Exosomes were isolated by ultracentrifugation, characterized via nanoparticle tracking analysis (NTA), Scanning Electron Microscopy (SEM) and Western blotting, and analyzed using high-resolution mass spectrometry. Comparative proteomics integrating exosomal profiles with the whole secretome were performed, followed by bioinformatic analyses of protein networks, gene ontology, and pathway enrichment. hCG reshaped exosomal cargo, identifying 59 proteins enriched in exosomes, including Integrin \u03b13 (ITG\u03b13), Galectin-3-binding protein (LGALS3BP), tetraspanins (CD63, CD151), and proteasome subunits. Functional enrichment indicated roles in extracellular matrix remodeling, integrin signaling, proteostasis, and steroidogenesis. Comparison with the secretome revealed distinct protein distributions, supporting selective exosomal packaging. Western blot confirmed increased ITG\u03b13 and LGALS3BP levels in exosomes upon hCG treatment. In conclusion, hCG modulates exosome cargo composition in granulosa cells, uncovering a novel mechanism of extracellular regulation.\n\nID: 42253155\nTitle: Engineered Exosomes Deliver miR-370 Inhibitor to Regulate DNAJB1 and Synergize With miR-25 in Improving SCA3 Mice Behavior and Neuropathology.\nAbstract: Spinocerebellar ataxia type 3 (SCA3), the most common inherited ataxia, lacks effective therapies. Current microRNA (miRNA) approaches directly targeting ataxin-3 (ATXN3) mRNA risk reducing essential wild-type ATXN3, a key regulator of proteostasis and various signaling pathways. Consequently, developing neuron-targeted, noninvasive miRNA delivery strategies that employ alternative mechanisms is critical for SCA3. In this study, we engineered rabies virus glycoprotein (RVG)-modified exosomes to deliver miR-370 inhibitors to the brains of SCA3 mice, thereby upregulating the molecular chaperone DnaJ homolog subfamily B member 1 (DNAJB1) to promote clearance of mutant ATXN3. Systemic administration of RVG-exosomes carrying miR-370 inhibitors led to increased DNAJB1 expression, reduced mutant ATXN3 aggregation, improved neuronal survival, and restored motor coordination in SCA3 mice. Furthermore, combining miR-370 inhibitors with miR-25-a miRNA that directly targets ATXN3 mRNA-synergistically enhanced the reduction of pathogenic ATXN3 and provided greater neuroprotection compared to either therapy alone. These findings support the use of RVG-exosome-mediated miR-370 inhibition as a noninvasive strategy to improve proteostasis in SCA3 and demonstrate its potential in combination with ATXN3 mRNA-targeting miRNAs, offering a promising therapeutic paradigm for SCA3 and similar neurodegenerative disorders.\n\nID: 42198466\nTitle: Rhizomes as Multi-Target Pharmacological Platforms Against Tauopathy: Neuro-Metabolic Crosstalk, Drug-Likeness, and Translational Challenges.\nAbstract: Tauopathies, including Alzheimer's disease (AD), progressive supranuclear palsy (PSP), corticobasal degeneration (CBD), and frontotemporal lobar degeneration with tau pathology, are unified by pathogenic tau misfolding, post-translational modification, aggregation, and network-level spread. Yet decades of drug development that predominantly pursued single nodes (e.g., one kinase, one aggregation inhibitor, one monoclonal antibody epitope) have repeatedly delivered late-stage disappointments, underscoring a central lesson: tauopathy behaves less like a linear pathway and more like a coupled system of proteostasis failure, neuroinflammation, synaptic-mitochondrial stress, and metabolic dysregulation. This review examines rhizomes (notably Zingiberaceae genera such as Curcuma, Zingiber, Alpinia, Kaempferia, and Boesenbergia) as chemically diverse \"multi-target platforms\" whose bioactives can engage several tau-relevant nodes simultaneously. We synthesise evidence across tau phosphorylation (GSK-3\u03b2/CDK5 and upstream stress signalling), tau aggregation and seeding, autophagy-lysosome and proteasome pathways, redox-mitochondrial resilience, neuroinflammatory circuits (NF-\u03baB/NLRP3), and neuro-metabolic signalling (insulin-PI3K-AKT, AMPK-mTOR). A translational lens is applied throughout, focusing on drug-likeness and CNS multiparameter optimisation; BBB permeability and efflux; metabolism and bioavailability constraints; and formulation strategies (nanoparticles, phytosomes, engineered exosomes) that may render rhizome-derived scaffolds more clinically plausible. We conclude that rhizomes offer credible mechanistic hypotheses for tau modulation, but progress depends on rigorous standardisation, realistic exposure matching, biomarker-driven study design, and a shift from \"single-compound optimism\" to network pharmacology with translational discipline.\n\nID: 42160006\nTitle: SIRT6-Mediated Deacetylation of ATF3 Promotes Silica-Induced Lung Fibrosis by Enhancing its Nuclear Import via Binding to Importin \u03b1.\nAbstract: Silicosis is the most common occupational lung disease caused by respirable crystalline silica inhalation, with limited therapeutic options. Cellular senescence plays a critical role in the pathogenesis of lung diseases, while the role of senescent macrophages in silicosis remains unclear. Single-cell RNA sequencing (scRNA-seq) of healthy and silicosis human and mouse lung tissues revealed that activating transcription factor 3 (ATF3)-mediated macrophage senescence is closely linked to silicosis progression. Mechanistically, Sirtuin 6 (SIRT6)-mediated ATF3 deacetylation enhanced its nuclear transport and subsequently activated mitochondria-localized glutamic acid-rich protein (MGARP) transcription, thereby causing mitochondrial dysfunction and macrophage senescence. Senescent macrophages promoted fibroblast activation via the secreted phosphoprotein 1 (SPP1)-cluster of differentiation 44 (CD44) signaling pathway. Furthermore, the nuclear transport protein importin \u03b1 and the molecular chaperone protein heat shock protein 70 (HSP70) competitively bound to ATF3, preventing its lysosomal degradation while promoting its nuclear import during macrophage senescence. Moreover, the small-molecule inhibitor Itraconazole, which targets the binding site of ATF3 and importin \u03b1, could reduce ATF3 nuclear entry, macrophage senescence, and pulmonary fibrosis (PF). Collectively, our study provided insights into the mechanism by which deacetylated ATF3 facilitates silicosis progression via increased nuclear transport and macrophage senescence, and indicated potential therapeutic targets for PF.\n\nID: 42112758\nTitle: Integrated clinical and computational data-based repurposing of econazole as a novel autophagic activator in ULK1-related Parkinson disease.\nAbstract: Parkinson disease (PD), the second most common neurodegenerative disorder, is pathologically linked to dysregulated autophagy, a conserved lysosomal degradation pathway. Current conventional PD therapies are often limited by significant side effects, underscoring the demand for alternative treatment strategies. Drug repurposing of FDA-approved compounds represents a promising approach to address this unmet clinical need. Here, by integrating clinical data analysis, we identified an association between autophagy impairment and specific PD patient subtypes, suggesting that ULK1-dependent autophagy activation may offer therapeutic benefit. Through systematic screening for autophagy induction and neuroprotective activity, we identified econazole, a known imidazole antifungal, as a promising candidate. Econazole exhibited robust therapeutic effects across multiple PD models, including MPTP-induced zebrafish and mouse models, as well as SNCAA53T mutant mouse models. Notably, its efficacy was dependent on functional autophagy, as autophagy inhibition abrogated its beneficial effects. Mechanistically, econazole activated ULK1, enhanced autolysosome formation, and promoted clearance of SNCA aggregates. Mouse brain microarray analysis indicated that econazole-activated ULK1 suppresses MAP3K12/DLK-MAPK8/JNK-MAPK9/JNK2-mediated neuronal apoptosis. Further phosphoproteomic profiling uncovered a novel ULK1-HSPA8/Hsc70 interaction that promotes LAMP1 and LAMP2 activation and enhances lysosomal function. This ULK1-HSPA8 complex additionally activated the BECN1 (beclin 1) complex to facilitate autophagosome formation. Together, our findings highlight a clinical data-guided drug repurposing approach that identifies econazole as a potent autophagy activator with therapeutic efficacy in ULK1-linked PD models, opening new avenues for PD treatment.Abbreviations: 3-MA: 3-methyladenine; ACTB: actin beta; ATG: autophagy related; AUC: area under the curve; BafA1: bafilomycin A1; BECN1: beclin 1; CMA: chaperone-mediated autophagy; DA: dopamine; DOPAC: 3,4-dihydroxyphenylacetic acid; Econ: econazole; GFP: green fluorescent protein; HEK-293T: human embryonic kidney 293T; HSPA8: heat shock protein 8 family A (Hsp70) member 8; HVA: homovanillic acid; JUN: Jun proto-oncogene, AP-1 transcription factor subunit; KSEA: kinase-substrate enrichment analysis; LAMP: lysosome associated membrane protein; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; MAP2K: mitogen-activated protein kinase kinase; MAP3K12: mitogen-activated protein kinase kinase kinase 12; MAPK: mitogen-activated protein kinase; MPP+: 1-methyl-4-phenylpyridinium; MPTP: 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine; PD: Parkinson disease; RB1CC1: RB1 inducible coiled-coil 1; RFP: red fluorescent protein; RMSD: root mean square deviation; SEM: standard error of the mean; SNCA: synuclein alpha; SQSTM1: sequestosome 1; SYP: synaptophysin; TFEB: transcription factor EB; TH: tyrosine hydroxylase; ULK1: unc-51 like autophagy activating kinase 1; WT: wild-type.\n\nID: 42084851\nTitle: Transient receptor potential channels in Flaviviridae infection: A comprehensive review.\nAbstract: Diseases caused by Flaviviridae viruses exert profound global health and economic burdens due to their high incidence and associated mortality. Infection by the Flaviviridae family often leads to severe acute or chronic illnesses, including hemorrhagic systemic diseases caused by dengue virus (DENV) and yellow fever virus, neurological complications associated with West Nile virus and Zika virus (ZIKV) infection, as well as liver damage and hepatocellular carcinoma resulting from hepatitis C virus (HCV) infection. Accumulating evidence indicates that a hallmark of Flaviviridae infection is to hijack calcium (Ca2+) signaling of the host cells, consequently facilitating viral entry, RNA replication, viral assembly, and release. Transient receptor potential (TRP) channels, a superfamily of nonselective cation channels, are central regulators of intracellular Ca2+ homeostasis. Recent studies reveal that TRP channels are closely involved in Flaviviridae infection. This comprehensive review synthesizes current findings on the role of TRP channels (e.g. TRPC, TRPV, TRPA, TRPM, and TRPML) in the pathogenesis of Flaviviridae viruses such as DENV, ZIKV, HCV, and Japanese encephalitis virus. Moreover, this review summarizes virus-TRP channel interaction mechanisms and discusses the potential of targeting TRP channels for host-directed antiviral therapies. This review aims to establish a conceptual framework for understanding TRP channel biology in Flaviviridae infection and to guide future research on antiviral strategies. Future directions should highlight the potential utility of TRP channel research for advancing anti-Flaviviridae therapies and clarifying their underlying 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: 41874277\nTitle: Hsp70-Targeting Chimeras Enable Dual Proteasomal and Lysosomal Degradation of Intracellular and Extracellular Proteins.\nAbstract: Developing targeted protein degradation (TPD) strategies with disease-specific mechanisms, modularity, and facile designability could ensure drug efficacy and selectivity. Herein, a small-molecule, Hsp70-based targeted protein degradation platform, termed Hsp70TAC, is described that enables tumor-selective degradation of both intracellular and extracellular proteins through distinct cellular pathways. By conjugating protein-of-interest (POI) ligands to Hsp70 inhibitors, Hsp70TACs exploits the chaperone functions of Hsp70 to enable protein degradation through both the ubiquitin-proteasome system and the endocytosis-lysosome pathway. As a proof of concept, Hsp70TACs induced efficient degradation of intracellular Bromodomain Protein 4 (BRD4) via the ubiquitin-proteasome system (DC50 = 0.67 \u03bcM) and membrane-bound Programmed Death Ligand 1 (PD-L1) via caveolin-mediated endocytosis-lysosomal processing (DC50 = 0.84 \u03bcM). Moreover, Hsp70TACs exploits the elevated expression of Hsp70 in tumor cells to preferentially accumulate in these cells, thereby enabling the tumor-selective degradation of POIs in Hsp70-enriched tumor cells.\n\nID: 41833626\nTitle: Autophagy-exosome crosstalk in neurodegeneration: Mechanisms and therapeutic opportunities.\nAbstract: Neurodegenerative diseases (NDs), including Alzheimer's, Parkinson's, Huntington's, amyotrophic lateral sclerosis, and multiple sclerosis, share a common pathogenic signature: disrupted proteostasis driven by impaired autophagy and maladaptive exosome dynamics. Under normal conditions, autophagy maintains neuronal homeostasis by clearing misfolded proteins and damaged organelles, while exosomes mediate neuroglial communication. When autophagic flux is impaired or lysosomal function is compromised, intracellular cargo handling can shift toward secretion and undegraded cargo may be redirected into exosomes/EVs, which disseminate pathogenic proteins such as amyloid-\u03b2, tau, \u03b1-synuclein, and TDP-43, a phenomenon reported in several experimental models and proposed to contribute to intercellular spread of pathology. This dual dysregulation amplifies neuroinflammation, demyelination, and progressive neuronal loss. Pharmacological strategies aimed at restoring the autophagy-exosome axis are gaining traction. Agents such as rapamycin and resveratrol enhance autophagic flux, whereas engineered or stem-cell-derived exosomes delivering siRNAs, neurotrophic factors, or anti-inflammatory microRNAs show promise in preclinical neuroprotection and immune modulation. However, translational barriers remain, including safety, biodistribution, dosing, and standardization. Emerging artificial intelligence (AI) and machine learning (ML) frameworks can accelerate translation by integrating multi-omics and exosomal biomarker datasets for early diagnosis, patient stratification, and therapy optimization. Deep learning and generative modeling may further enable rational drug design to fine-tune autophagy and engineer targeted exosome delivery to the brain. Collectively, these advances position the autophagy-exosome axis as an integrative framework linking intracellular clearance with intercellular signaling, with emerging diagnostic and therapeutic implications for neurodegenerative disorders.\n\nID: 41596312\nTitle: Investigating the Potential Role of Capsaicin in Facilitating the Spread of Coxsackievirus B3 via Extracellular Vesicles.\nAbstract: Coxsackievirus B3 (CVB3) is a picornavirus that causes systemic inflammatory diseases including myocarditis, pericarditis, pancreatitis, and meningoencephalitis. We have previously reported that CVB3 induces mitochondrial fission and mitophagy while inhibiting lysosomal degradation by blocking autophagosome-lysosome fusion. This promotes the release of virus-laden mitophagosomes from host cells as infectious extracellular vesicles (EVs), enabling non-lytic viral egress. Transient receptor potential vanilloid 1 (TRPV1), a heat and capsaicin-sensitive cation channel, regulates mitochondrial dynamics by inducing mitochondrial membrane depolarization and fission. In this study, we found that TRPV1 activation by capsaicin dramatically enhances CVB3 egress from host cells via EVs. Released EVs revealed increased levels of viral capsid protein VP1, mitochondrial protein TOM70, and fission protein phospho-DRP1. Moreover, these EVs were enriched in heat shock protein HSP70, suggesting its role in facilitating infectious EV release from cells. Furthermore, TRPV1 inhibition with capsazepine and SB-366791 significantly reduced viral infection in vitro. Our in vivo studies also found that SB-366791 significantly mitigates pancreatic damage and reduces viral titers in a mouse model of CVB3 pancreatitis. Given the lack of understanding regarding factors that contribute to diverse clinical manifestations of CVB3, our study highlights capsaicin and TRPV1 as potential exacerbating factors that facilitate CVB3 dissemination via mitophagy-derived EVs.\n\nID: 41471101\nTitle: A State-of-the-Art Overview on (Epi)Genomics and Personalized Skin Rejuvenating Strategies.\nAbstract: This article aims to point out new perspectives opened by genomics and epigenomics in skin rejuvenation strategies which target the main hallmarks of the ageing. In this respect, this article presents a concise overview on: the clinical relevance of the most important clocks and biomarkers used in skin anti-ageing strategy evaluation, the fundamentals, the main illustrating examples preclinically and clinically tested, the critical insights on knowledge gaps and future research perspectives concerning the most relevant skin anti-ageing and rejuvenation strategies based on novel epigenomic and genomic acquisitions. Thus the review dedicates distinct sections to: senolytics and senomorphics targeting senescent skin cells and their senescent-associated phenotype; strategies targeting genomic instability and telomere attrition by stimulation of the deoxyribonucleic acid (DNA) repair enzymes and proteins essential for telomeres' recovery and stability; regenerative medicine based on mesenchymal stem cells or cell-free products in order to restore skin-resided stem cells; genetically and chemically induced skin epigenetic partial reprogramming by using transcription factors or epigenetic small molecule agents, respectively; small molecule modulators of DNA methylases, histone deacetylases, telomerases, DNA repair enzymes or of sirtuins; modulators of micro ribonucleic acid (miRNA) and long-non-coding ribonucleic acid (HOTAIR's modulators) assisted or not by CRISPR-gene editing technology (CRISPR: Clustered Regularly Interspaced Short Palindromic Repeats); modulators of the most relevant altered nutrient-sensing pathways in skin ageing; as well as antioxidants and nanozymes to address mitochondrial dysfunctions and oxidative stress. In addition, some approaches targeting skin inflammageing, altered skin proteostasis, (macro)autophagy and intercellular connections, or skin microbiome, are very briefly discussed. The review also offers a comparative analysis among the newer genomic/epigenomic-based skin anti-ageing strategies vs. classical skin rejuvenation treatments from various perspectives: efficacy, safety, mechanism of action, evidence level in preclinical and clinical data and regulatory status, price range, current limitations. In these regards, a concise overview on senolytic/senomorphic agents, topical nutrigenomic pathways' modulators and DNA repair enzymes, epigenetic small molecules agents, microRNAs and HOTAIRS's modulators, is illustrated in comparison to classical approaches such as tretinoin and peptide-based cosmeceuticals, topical serum with growth factors, intense pulsed light, laser and microneedling combinations, chemical peels, botulinum toxin injections, dermal fillers. Finally, the review emphasizes the future research directions in order to accelerate the clinical translation of the (epi)genomic-advanced knowledge towards personalization of the skin anti-ageing strategies by integration of individual genomic and epigenomic profiles to customize/tailor skin rejuvenation therapies.\n\nID: 41429925\nTitle: Mitochondrial proteostasis regulated by CRL5Ozz and Alix modulates skeletal muscle metabolism and fiber type.\nAbstract: High-energy-demanding tissues, such as skeletal muscle, rely on mitochondrial proteostasis for proper function. Two key quality-control mechanisms -the ubiquitin proteasome system (UPS) and the release of mitochondria-derived vesicles- help maintain mitochondrial proteostasis, but whether these processes interact remains unclear. Here, we show that CRL5Ozz and its substrate, Alix, localize to mitochondria and together regulate the levels and distribution of the mitochondrial solute carrier Slc25A4, which is essential for ATP production. In Ozz-/- or Alix-/- mice, skeletal muscle mitochondria exhibit similar morphological abnormalities, including swelling and dysmorphism, along with partially overlapping metabolomic alterations. We demonstrate that CRL5Ozz ubiquitinates Slc25A4, targeting it for proteasomal degradation, while Alix facilitates Slc25A4 loading into exosomes for lysosomal degradation. Loss of Ozz or Alix in vivo disrupts the steady-state levels of Slc25A4, impairing mitochondrial metabolism and triggering a switch in muscle fiber composition from oxidative, mitochondria-rich slow to glycolytic fast fibers.\n\nID: 41173847\nTitle: Super enhancer lncRNA RP11-54O7.17 regulates the proliferation and metastasis of triple-negative breast cancer by targeting lysosomal degradation of S100A4.\nAbstract: Triple-negative breast cancer (TNBC) is characterized by its high aggressiveness and treatment resistance, with limited therapeutic options and especially a lack of effective targeted therapeutic strategies. This study focuses on the role and regulatory mechanisms of super enhancer long non-coding RNA (SE-lncRNA) in TNBC. Through in-depth analysis of TCGA database, we revealed the specific expression pattern of SE-lncRNA in TNBC, and found that downregulation of RP11-54O7.17 was significantly correlated with poor prognosis of TNBC patients, which was experimentally verified. Both in vitro and in vivo results confirmed that RP11-54O7.17 overexpression effectively suppressed the proliferation and metastasis of TNBC. Further exploration showed that RP11-54O7.17 directly interacted with the S100A4 protein through its conserved L2b-type repeat structural fragment, promoted S100A4 binding to HSP70, targeting S100A4 degradation via the autophagy-lysosome pathway, which in turn blocked the activation of S100A4-STAT3 signaling axis. Moreover, RP11-54O7.17 delivered via liposome demonstrated significant anti-TNBC efficacy in an in vivo model without observing significant systemic toxicity. This study elucidates the regulatory role and molecular mechanism of RP11-54O7.17 in TNBC, which provides a strong scientific basis and potential therapeutic targets for the development of novel SE-lncRNA-based therapeutic strategies.\n\nID: 41146020\nTitle: Cellular and molecular mechanisms underlying cardiovascular aging.\nAbstract: Aging is a primary risk factor driving the increased prevalence of cardiovascular diseases, significantly contributing to global mortality and healthcare burdens. Aging-related alterations, including genomic instability, telomere shortening, and loss of proteostasis, underpin the pathogenesis of numerous cardiovascular conditions such as heart failure, arrhythmia, cardiomyopathy, myocardial infarction, and atherosclerosis. Recent insights into molecular and cellular mechanisms highlight the roles of senescence, inflammation, mitochondrial dysfunction, and metabolic disturbances in cardiovascular aging. Cellular and vascular senescence further accelerates the development of aging-related cardiovascular diseases. Emerging therapeutic strategies targeting these pathways, such as metabolic regulators, senolytic agents, antioxidants, stem cell-derived exosomes, and natural bioactive compounds, offer promising avenues for mitigating aging-related cardiovascular pathology.\n\nID: 41099453\nTitle: Acetylation promotes mutant (MUT) TP53-HSPA8 and HSPA8-BAG3 interactions, facilitating MUT TP53 lysosomal degradation preferentially via CASA.\nAbstract: Targeting mutant (MUT) TP53 is crucial in anticancer therapy, given the oncogenic properties that these proteins often acquire. Therefore, it is of paramount importance to unravel strategies and mechanisms through which this goal can be achieved. Valproic acid (VPA) downregulates the expression of MUT TP53 in several tumor cells, although the mechanisms involved remain to be explored. Here, we demonstrate for the first time that acetylation induced by VPA promotes the lysosomal degradation of MUT TP53 and that it occurs preferentially through chaperone-assisted selective autophagy (CASA). Indeed, acetylation of MUT TP53 increases its interaction with STUB1 (STIP1\u00a0homology and U-box containing protein 1), HSPB8 (heat shock protein family B (small) member 8) and HSPA8 (heat shock protein family A (Hsp70) member 8) and the latter, itself acetylated by VPA, binds to BAG3 (BAG cochaperone 3), facilitating the recruitment of MUT TP53 into the CASA pathway. These findings elucidate the mechanisms through which acetylation leads to the selective lysosomal clearance of MUT TP53, highlighting a potential therapeutic vulnerability of aggressive tumors expressing this oncoprotein.Abbreviations: ACTB: actin beta; ATG5: autophagy related 5; BAF: bafilomycin A1; CMA: chaperone-mediated autophagy; GAPDH: glyceraldehyde-3-phosphate dehydrogenase; HSPA8: heat shock protein family A (Hsp70) member 8; LAMP2A: lysosomal associated membrane protein 2A; MAP1LC3B: microtubule associated protein 1 light chain 3 beta; SQSTM1: sequestosome 1; TP53: tumor protein p53.\n\nID: 40947322\nTitle: Heat shock protein 70 (Hsp70) as a target for advancing immunotherapy in solid tumors.\nAbstract: Heat shock protein 70 (Hsp70) is a highly conserved molecular chaperone that maintains protein homeostasis (proteostasis) under stress conditions. In cancer, Hsp70 is frequently overexpressed, where it contributes to hallmark features of malignancy by stabilizing oncogenic proteins, suppressing apoptosis, and promoting invasion and immune evasion. Beyond its intracellular functions, Hsp70 is aberrantly presented on the plasma membrane of a broad range of solid tumor cells and actively released into the extracellular space, either in soluble form or encapsulated within extracellular lipid microvesicles with biophysical characteristics of exosomes, supporting tumor microenvironment remodeling and immune modulation. The selective surface expression of Hsp70 on tumor cells, but not healthy tissues, defines it as a tumor-associated antigen (TAA) and an accessible target for immunotherapy. Leveraging this unique feature, several therapeutic approaches have been developed addressing membrane Hsp70 on tumor cells, including small molecule inhibitors, peptide-mediated activation of natural killer (NK) cells, monoclonal antibodies, fusion vaccines, and chimeric antigen receptor (CAR)-engineered immune cells. In parallel, extracellular Hsp70 in the blood is emerging as a promising liquid biomarker for patient stratification and treatment monitoring in cancer patients. This review outlines the context-dependent roles of Hsp70 in cancer and critically evaluates its translational potential as both a therapeutic target and diagnostic marker in solid tumors. We also discuss advances in detection technologies, findings from early-phase clinical trials, and persistent challenges such as off-target effects, tumor heterogeneity, and achieving effective and selective targeting.\n\nID: 40946428\nTitle: Artesunate induces ferroptosis in gastric cancer by targeting the TFRC-HSPA9 axis for iron homeostasis regulation.\nAbstract: Ferroptosis, a recently characterized form of regulated cell death driven by iron-dependent lipid peroxidation, has emerged as a promising therapeutic strategy for cancer treatment due to its potential for selectively targeting cancer cells. Exploiting FDA-approved drugs to induce ferroptosis offers a novel approach that exploits cancer cells' vulnerabilities in iron metabolism and oxidative stress. Here, we identify artesunate, an antimalarial drug, as a potent inducer of ferroptosis in gastric cancer cells and reveal the transferrin receptor (TFRC) as a key mediator in this process. Notably, our study is the first to demonstrate an interaction between artesunate and TFRC through molecular docking and surface plasmon resonance (SPR) experiments, highlighting a novel mechanism by which artesunate stabilizes TFRC by inhibiting its lysosomal degradation. This stabilization is regulated via the heat shock protein HSPA9, another previously unreported interaction. Disrupting the TFRC-HSPA9 interaction facilitates iron accumulation and lipid peroxidation, hallmark features of ferroptosis, leading to significant cancer cell death. Additionally, in vivo studies confirm artesunate's anti-tumor efficacy, showing marked tumor growth inhibition and minimal systemic toxicity. These findings underscore the therapeutic relevance of targeting ferroptosis in cancer, particularly by leveraging TFRC's role in iron homeostasis. Furthermore, this study expands the understanding of post-translational regulation in ferroptosis, offering a new perspective on the role of artesunate in cancer therapy.\n\nID: 40891497\nTitle: Autophagy and exosomes play different roles in the disposal of unwanted cellular materials.\nAbstract: Degradative autophagy supplies a source of nutrients and energy by digesting cytoplasmic components. Additionally, it eliminates toxic protein aggregates and defective organelles from cells. Exosomes are small vesicles that are released by cells into the extracellular environment and are also involved in maintenance of homeostasis by removing unwanted materials and intracellular pathogens. Nevertheless, it remains unclear how these two processes may differ or are alike in their roles in maintaining intracellular homeostasis. In this study, we found that secretory exosomes served as a quality control mechanism, maintaining intracellular RNA homeostasis by facilitating both the selective packaging of endogenous and exogenous RNA species. Conversely, autophagic degradation primarily functions to dispose of both endogenous and exogenous proteins, resulting in controlling intracellular proteostasis. The depletion of exosome secretion resulted in prolonged accumulation of exogenous RNA within the cells, whereas it had no significant effect on the accumulation of exogenous proteins. Viral infection not only induced the host autophagy response, but also impacted secretion of exosomes. Our data showed that secretory exosomes contributed to the clearing of increased intracellular microRNAs induced by enterovirus infection, thereby weakening viral replication. Furthermore, the secretory exosomes were essential for the disposal of viral RNA replicon rather than autophagic degradation, thereby facilitating host survival. Our results collectively revealed that both secretory exosome and autophagic degradation were crucial for maintaining cellular homeostasis, but that they operate through distinct mechanisms and dispose of different types of unwanted materials.\n\nID: 40624965\nTitle: Molecular Mechanisms of Extracellular Vesicle Biogenesis and Their Impact on the Design of Custom EVs.\nAbstract: Extracellular Vesicles (EVs) are nanosized lipid-bound particles that are pivotal for intercellular communication and actively participate in diverse physiological processes, including immune modulation, proteostasis, and tissue repair. EVs have emerged as promising therapeutic targets and biomarkers because of their significant roles in the pathogenesis of diseases, including cancer, neurodegeneration, and cardiovascular disorders. Despite extensive research on EVs as diagnostic tools and mediators of cellular signaling, the fundamental mechanisms underlying their biogenesis remain unclear. Consequently, this understanding of how the composition of EVs dynamically changes in response to physiological and pathological conditions is often limited, leading to lower diagnostic utility and slower advancements in clinical interventions and EVs engineering. This review explores the intricate mechanisms underlying EVs biogenesis and payload selection, emphasizing how these processes vary across EVs subclasses, thereby underpinning their functional versatility. The biogenetic pathways are highlighted from the ectocytosis-driven generation of microvesicles and apoptotic body (ApoBDs) formation via membrane blebbing to the formation of exosomes within the endosomal compartments and their regulated release via exocytosis.\n\nID: 40349806\nTitle: Mesenchymal stem cells and exosomes: A novel therapeutic approach for aging.\nAbstract: Mesenchymal stem cells (MSCs), a vital component of the adult stem cell repertoire, are distinguished by their dual capacity for self-renewal and multilineage differentiation. The therapeutic effects of MSCs are primarily mediated through mechanisms such as homing, paracrine signaling, and cellular differentiation. Exosomes (Exos), a type of extracellular vesicles (EVs) secreted by MSCs via the paracrine pathway, play a pivotal role in conveying the biological functions of MSCs. Accumulating evidence from extensive research underscores the remarkable anti-aging potential of both MSCs and their Exos. This review comprehensively explores the impact of MSCs and their Exos on key hallmarks of aging, including genomic instability, telomere attrition, epigenetic alterations, loss of proteostasis, impaired macroautophagy, deregulated nutrient-sensing, mitochondrial dysfunction, cellular senescence, stem cell exhaustion, altered intercellular communication, chronic inflammation, and dysbiosis. Furthermore, this paper highlights emerging strategies and novel approaches for modulating the aging process, offering insights into potential therapeutic interventions.\n\nID: 39800177\nTitle: Intercellular communication is crucial in the regulation of healthy aging via exosomes.\nAbstract: The hallmarks of aging encompass a variety of molecular categories (genomic, telomeric, and epigenetic), organelles (proteostasis, autophagy, and mitochondria), cellular components (including stem cells), systems (such as intercellular communication and chronic inflammation), and environmental factors (dysbiosis and nutrient sensing). These hallmarks play a crucial role in the aging process. Despite their intricate interconnections, the relationships among the hallmarks of aging remain unclear. Although the boundaries between these hallmarks may be indistinct, they exhibit interdependence, with the influence of one hallmark extending to others. Building on this foundation, we investigated the interrelations among the various hallmarks of aging and provided a systematic overview of their logical relationships, proposing that cellular communication plays a crucial role in the aging process. Exosomes function as a primary mode of cellular communication and significantly impact the aging process. Therefore, we propose utilizing exosomes as valuable tools for understanding the mechanisms of aging and addressing age-related concerns. Exosomes may represent a novel approach for the treatment and diagnosis of aging-related conditions in animals. Furthermore, our research reveals that exocytosis in young nematodes slows the aging process, while exocytosis in aged nematodes has the opposite effect, accelerating aging. In conclusion, exosomes act as intercellular messengers that influence the maintenance of a healthy aging process and link the hallmarks of aging with indicators of well-being.\n\nID: 39677700\nTitle: Investigating the potential role of capsaicin in facilitating the spread of coxsackievirus B3 via extracellular vesicles.\nAbstract: Coxsackievirus B3 (CVB3) is a non-enveloped picornavirus that can cause systemic inflammatory diseases including myocarditis, pericarditis, pancreatitis, and meningoencephalitis. We have previously reported that following infection, CVB3 localizes to mitochondria, inducing mitochondrial fission and mitophagy, while inhibiting lysosomal degradation by blocking autophagosome-lysosome fusion. This results in the release of virus-laden mitophagosomes from the host cell as infectious extracellular vesicles (EVs) which allow non-lytic viral egress. Transient receptor potential vanilloid 1 (TRPV1/ TRPV1 ) is a heat and capsaicin-sensitive cation channel that regulates mitochondrial dynamics by inducing mitochondrial membrane depolarization and fission. In this study, we found that treating cells with the TRPV1 agonist capsaicin dramatically enhances CVB3 egress via EVs. Analysis of the released EVs revealed increased levels of viral capsid protein VP1/ VP1 , mitochondrial protein TOM70/ TOMM70 , and fission protein phospho-DRP1/ DNM1L (Ser 616). Moreover, these EVs exhibited increased levels of heat shock protein HSP70/ HSPA1A , suggesting a potential role of these chaperones in facilitating infectious EV release from cells. Furthermore, TRPV1 inhibition with capsazepine significantly reduced viral infection in vitro . We previously observed similar effects in vitro with another TRPV1 inhibitor SB-366791. Our current in vivo studies found that SB-366791 significantly mitigates pancreatic damage and reduces viral titers in mouse model of CVB3 pancreatitis. Given the lack of understanding regarding the factors that contribute to diverse clinical manifestations of CVB3, our study highlights capsaicin and TRPV1 as potential exacerbating factors that facilitates CVB3 dissemination via mitophagy-derived EVs. CVB3 is a prevalent pathogen responsible for a range of severe diseases, including myocarditis, pericarditis, pancreatitis, and meningoencephalitis. Despite its clinical significance, factors that determine the severity of CVB3 infection and why some individuals experience life-threatening manifestations while others have mild, cold-like symptoms remain poorly understood. This study provides new insights into the molecular mechanisms underlying CVB3 dissemination and pathogenesis. By investigating the role of capsaicin, a common dietary component, in modulating viral spread, we demonstrate that activation of TRPV1 by capsaicin enhances release of infectious CVB3 via mitophagy-derived EVs. Our results offer novel evidence that modulating TRPV1 activity could influence the clinical outcomes of CVB3 infection, opening new avenues for therapeutic interventions. Given the widespread consumption of capsaicin, this study highlights an important dietary factor that could play a role in shaping CVB3 pathogenesis and its clinical manifestations, underscoring the potential for targeted strategies to mitigate severe disease outcomes.\n\nID: 39611307\nTitle: Impaired chaperone-mediated autophagy leads to abnormal SORT1 (sortilin 1) turnover and CES1-dependent triglyceride hydrolysis.\nAbstract: SORT1 (sortilin 1), a member of the the Vps10 (vacuolar protein sorting 10) family, is involved in hepatic lipid metabolism by regulating very low-density lipoprotein (VLDL) secretion and facilitating the lysosomal degradation of CES1 (carboxylesterase 1), crucial for triglyceride (TG) breakdown in the liver. This study explores whether SORT1 is targeted for degradation by chaperone-mediated autophagy (CMA), a selective protein degradation pathway that directs proteins containing KFERQ-like motifs to lysosomes via LAMP2A (lysosomal-associated membrane protein 2A). Silencing LAMP2A or HSPA8/Hsc70 with siRNA increased cytosolic SORT1 protein levels. Leupeptin treatment induced lysosomal accumulation of SORT1, unaffected by siLAMP2A co-treatment, indicating CMA-dependent degradation. Human SORT1 contains five KFERQ-like motifs (658VVTKQ662, 730VREVK734, 733VKDLK737, 734KDLKK738, and 735DLKKK739), crucial for HSPA8 recognition; mutating any single amino acid within these motifs decreased HSPA8 binding. Furthermore, compromised CMA activity resulted in elevated SORT1-mediated degradation of CES1, contributing to increased lipid accumulation in hepatocytes. Consistent with in vitro findings, LAMP2A knockdown in mice exacerbated high-fructose diet-induced fatty liver, marked by increased SORT1 and decreased CES1 levels. Conversely, LAMP2A overexpression promoted SORT1 degradation and CES1D accumulation, counteracting fasting-induced CES1D suppression through CMA activation. Our findings reveal that SORT1 is a substrate of CMA, highlighting its crucial role in directing CES1 to lysosomes. Consequently, disrupting CMA-mediated SORT1 degradation significantly affects CES1-dependent TG hydrolysis, thereby affecting hepatic lipid homeostasis.Abbreviations: APOB: apolipoprotein B; CES1: carboxylesterase 1; CMA: chaperone-mediated autophagy; HSPA8/Hsc70: heat shock protein family A (Hsp70) member 8; LAMP2A: lysosomal associated membrane protein 2A; LDL-C: low-density lipoprotein-cholesterol; PLIN: perilipin; SORT1: sortilin 1; TG: triglyceride; VLDL: very low-density lipoprotein; Vps10: vacuolar protein sorting 10.\n\nID: 39551273\nTitle: Exploring heat shock proteins as therapeutic targets for Parkinson's disease.\nAbstract: Parkinson's disease (PD) is characterized by the accumulation of misfolded \u03b1-synuclein (\u03b1-syn). Promoting the degradation of misfolded proteins has been shown to be an effective approach to alleviate PD. This review highlights the roles of specific heat shock proteins (HSPs) in modulating \u03b1-syn aggregation and neuronal survival. HSP27 prevents glycosylation-induced \u03b1-syn aggregation, disrupts copper ion interactions, inhibits mitochondrial apoptosis, and prevents dopaminergic neuronal cell death. HSP70 alleviates dopaminergic neuronal damage by promoting mitophagy and preventing neuronal apoptosis. HSC70 plays a critical role in chaperone-mediated autophagy and facilitates lysosomal degradation. GRP78 mitigates abnormal protein aggregation. The HSP70-HSP40-HSP110 system is capable of degrading \u03b1-syn amyloid fibers. Inhibition of HSP90 expression protects neurons. Further research should prioritize developing regulators of HSPs as treatments for PD. While HSPs offer promise in PD management, their complex roles necessitate cautious therapeutic development to harness their potential. Understanding the specific roles of different HSPs will be essential to developing effective therapies for \u03b1-syn clearance.\n\nID: 39427885\nTitle: Mitochondria break free: Mitochondria-derived vesicles in aging and associated conditions.\nAbstract: Mitophagy is the intracellular recycling system that disposes damaged/inefficient mitochondria and allows biogenesis of new organelles to ensure mitochondrial quality is optimized. Dysfunctional mitophagy has been implicated in human aging and diseases. Multiple evolutionarily selected, redundant mechanisms of mitophagy have been identified, but their specific roles in human health and their potential exploitation as therapeutic targets are unclear. Recently, the characterization of the endosomal-lysosomal system has revealed additional mechanisms of mitophagy and mitochondrial quality control that operate via the production of mitochondria-derived vesicles (MDVs). Circulating MDVs can be isolated and characterized to provide an unprecedented opportunity to study this type of mitochondrial recycling in vivo and to relate it to human physiology and pathology. Defining the role of MDVs in human physiology, pathology, and aging is hampered by the lack of standardized methods to isolate, validate, and characterize these vesicles. Hence, some basic questions about MDVs remain unanswered. While MDVs are generated directly through the extrusion of mitochondrial membranes within the cell, a set of circulating extracellular vesicles leaking from the endosomal-lysosomal system and containing mitochondrial portions have also been identified and warrant investigation. Preliminary research indicates that MDV generation serves multiple biological roles and contributes to restoring cell homeostasis. However, studies have shown that MDVs may also be involved in pathological conditions. Therefore, further research is warranted to establish when/whether MDVs are supporting disease progression and/or are extracting damaged mitochondrial components to alleviate cellular oxidative burden and restore redox homeoastasis. This information will be relevant for exploiting these vesicles for therapeutic purpose. Herein, we provide an overview of preclinical and clinical studies on MDVs in aging and associated conditions and discuss the interplay between MDVs and some of the hallmarks of aging (mitophagy, inflammation, and proteostasis). We also outline open questions on MDV research that should be prioritized by future investigations.\n\nID: 39409015\nTitle: SILAC-Based Characterization of Plasma-Derived Extracellular Vesicles in Patients Undergoing Partial Hepatectomy.\nAbstract: Post-hepatectomy liver failure (PHLF) remains a significant risk for patients undergoing partial hepatectomy (PHx). Reliable prognostic markers and treatments to enhance liver regeneration are lacking. Plasma nanoparticles, including lipoproteins, exosomes, and extracellular vesicles (EVs), can reflect systemic and tissue-wide proteostasis and stress, potentially aiding liver regeneration. However, their role in PHLF is still unknown. Our study included nine patients with hepatocellular carcinoma (HCC) undergoing PHx: three patients with PHLF, three patients undergoing the associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) procedure, and three matched controls without complications after PHx. Patient plasma was collected before PHx as well as 1 and 5 days after. EVs were isolated by ultracentrifugation, and extracted proteins were subjected to quantitative mass spectrometry using a super-SILAC mix prepared from primary and cancer cell lines. We identified 2625 and quantified 2570 proteins in the EVs of PHx patients. Among these, 53 proteins were significantly upregulated and 32 were downregulated in patients with PHLF compared to those without PHLF. Furthermore, 110 proteins were upregulated and 78 were downregulated in PHLF patients compared to those undergoing ALPPS. The EV proteomic signature in PHLF indicates significant disruptions in protein translation, proteostasis, and intracellular vesicle biogenesis, as well as alterations in proteins involved in extracellular matrix (ECM) remodelling and the metabolic and cell cycle pathways, already present before PHx. Longitudinal proteomic analysis of the EVs circulating in the plasma of human patients undergoing PHx uncovers proteomic signatures associated with PHLF, which reflect dying hepatocytes and endothelial cells and were already present before PHx.\n\nID: 39338351\nTitle: Myrtus communis L. Essential Oil Exhibits Antiviral Activity against Coronaviruses.\nAbstract: Human coronaviruses are a continuous threat to the human population and have limited antiviral treatments, and the recent COVID-19 pandemic sparked interest in finding new antiviral strategies, such as natural products, to combat emerging coronaviruses. Rapid efforts in the scientific community to identify effective antiviral agents for coronaviruses remain a focus to minimize mortalities and global setbacks. In this study, an essential oil derived from Myrtus communis L. (MEO) is effective against HCoV-229E and HCoV-OC43 virus infections in comparison to two FDA-approved drugs, Remdesivir and Nirmatrelvir. Gas-chromatography and mass spectrometry were used to identify the chemical composition of MEO. Slight antioxidant activity was observed in MEO, indicating a role in oxidative stress. A dose-response curve measuring the EC50 indicates a high potency against HCoV-229E and HCoV-OC43 virus infections on Huh7.5 cells with low cytotoxicity using a PrestoBlue cell viability assay. Our findings demonstrate that MEO exhibits potent antiviral activity against HCoV-229E and HCoV-OC43 on Huh7.5 cells within a low-cytotoxicity range, but not on SARS-CoV-2. Artificial bacterial chromosome plasmids that expressed SARS-CoV-2 used for replicon-to determine viral replication and viral assembly/egress on HEK293T/17 cells-and virus-like particles on Huh7.5-AT cells-to determine viral entry and assembly/egress-showed no antiviral activity with MEO in comparison to Remdesivir. This study reveals the potential effectiveness of MEO as an alternative natural remedy to treat human coronaviruses and a potential antiviral agent for future coronavirus infections.\n\nID: 39215782\nTitle: Exosomal misfolded proteins released by cancer stem cells: dual functions in balancing protein homeostasis and orchestrating tumor progression.\nAbstract: Cancer stem cells (CSCs), the master regulators of tumor heterogeneity and progression, exert profound influence on cancer metastasis, via various secretory vesicles. Emerging from CSCs, the exosomes serve as pivotal mediators of intercellular communication within the tumor microenvironment, modulating invasion, angiogenesis, and immune responses. Moreover, CSC-derived exosomes play a central role in sculpting a dynamic landscape, contributing to the malignant phenotype. Amidst several exosomal cargoes, misfolded proteins have recently gained attention for their dual functions in maintaining protein homeostasis and promoting tumor progression. Disrupting these communication pathways could potentially prevent the maintenance and expansion of CSCs, overcome treatment resistance, and inhibit the supportive environment created by the tumor microenvironment, thereby improving the effectiveness of cancer therapies and reducing the risk of tumor recurrence and metastasis. Additionally, exosomes have also shown potential therapeutic applications, such as in drug delivery or as biomarkers for cancer diagnosis and prognosis. Therefore, comprehending the biology of exosomes derived from CSCs is a multifaceted area of research with implications in both basic sciences and clinical applications. This review explores the intricate interplay between exosomal misfolded proteins released by CSCs, the potent contributor in tumor heterogeneity, and their impact on cellular processes, shedding light on their role in cancer progression.\n\nID: 38711329\nTitle: Thermotolerance in S. cerevisiae as a model to study extracellular vesicle biology.\nAbstract: The budding yeast Saccharomyces cerevisiae is a proven model organism for elucidating conserved eukaryotic biology, but to date its extracellular vesicle (EV) biology is understudied. Here, we show yeast transmit information through the extracellular medium that increases survival when confronted with heat stress and demonstrate the EV-enriched samples mediate this thermotolerance transfer. These samples contain vesicle-like particles that are exosome-sized and disrupting exosome biogenesis by targeting endosomal sorting complexes required for transport (ESCRT) machinery inhibits thermotolerance transfer. We find that Bro1, the yeast ortholog of the human exosome biomarker ALIX, is present in EV samples, and use Bro1 tagged with green fluorescent protein (GFP) to track EV release and uptake by endocytosis. Proteomics analysis reveals that heat shock protein 70 (HSP70) family proteins are enriched in EV samples that provide thermotolerance. We confirm the presence of the HSP70 ortholog stress-seventy subunit A2 (Ssa2) in EV samples and find that mutant yeast cells lacking SSA2 produce EVs but they fail to transfer thermotolerance. We conclude that Ssa2 within exosomes shared between yeast cells contributes to thermotolerance. Through this work, we advance Saccharomyces cerevisiae as an emerging model organism for elucidating molecular details of eukaryotic EV biology and establish a role for exosomes in heat stress and proteostasis that seems to be evolutionarily conserved.\n\nID: 38569476\nTitle: HSPA8 Chaperone Complex Drives Chaperone-Mediated Autophagy Regulation in Acute Promyelocytic Leukemia Cell Differentiation.\nAbstract: Acute myeloid leukemia (AML) is a cancer of the hematopoietic system characterized by hyperproliferation of undifferentiated cells of the myeloid lineage. While most of AML therapies are focused toward tumor debulking, all-trans retinoic acid (ATRA) induces neutrophil differentiation in the AML subtype acute promyelocytic leukemia (APL). Macroautophagy has been extensively investigated in the context of various cancers and is often dysregulated in AML where it can have context-dependent pro- or anti-leukemogenic effects. On the contrary, the implications of chaperone-mediated autophagy (CMA) on the pathophysiology of diseases are still being explored and its role in AML remains elusive. We took advantage of human AML primary samples and databases to analyze CMA gene expression and activity. Furthermore, we used ATRA-sensitive (NB4) and -resistant (NB4-R1) APL cells to further dissect a potential function for CMA in ATRA-mediated neutrophil differentiation. NB4-R1 cells are unique in that they do respond to retinoic acid transcriptionally but do not mature in response to retinoid signaling alone unless maturation is triggered by adding cyclic adenosine monophosphate. Here, we report that CMA-related mRNA transcripts are significantly higher expressed in immature hematopoietic cells as compared to neutrophils, contrasting the macroautophagy gene expression patterns. Accordingly, lysosomal degradation of an mCherry-KFERQ CMA reporter decreases during ATRA-induced differentiation of APL cells. On the other hand, using NB4-R1 cells we found that macroautophagy flux primed ATRA-resistant NB4-R1 cells to differentiate upon ATRA treatment but reduced the association of lysosome-associated membrane protein type 2A (LAMP-2A) and heat shock protein family A (Hsp70) member 8 (HSPA8), necessary for complete neutrophil maturation. Accordingly, depletion of HSPA8 attenuated CMA activity and facilitated APL cell differentiation. In contrast, maintaining high CMA activity by ectopic expression of LAMP-2A impeded APL differentiation. Overall, our findings suggest that APL neutrophil differentiation requires CMA inactivation and that this pathway predominantly depends on HSPA8 and is possibly assisted by other co-chaperones.\n\nID: 38247818\nTitle: Heat Shock Protein SSA1 Enriched in Hypoxic Secretome of Candida albicans Exerts an Immunomodulatory Effect via Regulating Macrophage Function.\nAbstract: Candida albicans is an opportunistic pathogenic yeast that can survive in both normoxic and hypoxic environments. The involvement of C. albicans secretome on host biological processes has been demonstrated. However, the immunoregulatory function of C. albicans secretome released under hypoxic condition remains unclear. This study demonstrated the differences in cytokine responses and protein profiles between secretomes prepared under normoxic and hypoxic conditions. Furthermore, the immunoregulatory effects of heat shock protein SSA1(Ssa1), a protein candidate enriched in the hypoxic secretome, were investigated. Stimulation of mouse bone marrow-derived macrophages (BMMs) with Ssa1 resulted in the significant production of interleukin (IL)-10, IL-6, and tumor necrosis factor (TNF)-\u03b1 as well as the significant expression of M2b macrophage markers (CD86, CD274 and tumor necrosis factor superfamily member 14), suggesting that C. albicans Ssa1 may promote macrophage polarization towards an M2b-like phenotype. Proteomic analysis of Ssa1-treated BMMs also revealed that Ssa1 reduced inflammation-related factors (IL-18-binding protein, IL-1 receptor antagonist protein, OX-2 membrane glycoprotein and cis-aconitate decarboxylase) and enhanced the proteins involved in anti-inflammatory response (CMRF35-like molecule 3 and macrophage colony-stimulating factor 1 receptor). Based on these results, we investigated the effect of Ssa1 on C. albicans infection and showed that Ssa1 inhibited the uptake of C. albicans by BMMs. Taken together, our results suggest that C. albicans alters its secretome, particularly by promoting the release of Ssa1, to modulate host immune response and survive under hypoxic conditions.\n\nID: 38191961\nTitle: Novel method for collecting hippocampal interstitial fluid extracellular vesicles (EVISF ) reveals sex-dependent changes in microglial EV proteome in response to A\u03b2 pathology.\nAbstract: Brain-derived extracellular vesicles (EVs) play an active role in Alzheimer's disease (AD), relaying important physiological information about their host tissues. The internal cargo of EVs is protected from degradation, making EVs attractive AD biomarkers. However, it is unclear how circulating EVs relate to EVs isolated from disease-vulnerable brain regions. We developed a novel method for collecting EVs from the hippocampal interstitial fluid (ISF) of live mice. EVs (EVISF ) were isolated via ultracentrifugation and characterized by nanoparticle tracking analysis, immunogold labelling, and flow cytometry. Mass spectrometry and proteomic analyses were performed on EVISF cargo. EVISF were 40-150\u00a0nm in size and expressed CD63, CD9, and CD81. Using a model of cerebral amyloidosis (e.g., APPswe, PSEN1dE9 mice), we found protein concentration increased but protein diversity decreased with A\u03b2 deposition. Genotype, age, and A\u03b2 deposition modulated proteostasis- and immunometabolic-related pathways. Changes in the microglial EVISF proteome were sexually dimorphic and associated with a differential response of plaque associated microglia. We found that female APP/PS1 mice have more amyloid plaques, less plaque associated microglia, and a less robust- and diverse- EVISF microglial proteome. Thus, in vivo microdialysis is a novel technique for collecting EVISF and offers a unique opportunity to explore the role of EVs in AD.\n\nID: 38035334\nTitle: Extracellular vesicle storm during the course of Ebola virus infection in primates.\nAbstract: Ebola virus (EBOV) is an RNA virus of the Filoviridae family that is responsible for outbreaks of hemorrhagic fevers in primates with a lethality rate as high as 90%. EBOV primarily targets host macrophages leading to cell activation and systemic cytokine storm, and fatal infection is associated with an inhibited interferon response, and lymphopenia. The EBOV surface glycoprotein (GP) has been shown to directly induce T cell depletion and can be secreted outside the virion via extracellular vesicles (EVs), though most studies are limited to epithelial cells and underlying mechanisms remain poorly elucidated. To assess the role of GP on EBOV-induced dysregulation of host immunity, we first utilized EBOV virus-like particles (VLPs) expressing VP40 and NP either alone (Bald-VLP) or in conjunction with GP (VLP-GP) to investigate early inflammatory responses in THP-1 macrophages and in a murine model. We then sought to decipher the role of non-classical inflammatory mediators such as EVs over the course of EBOV infection in two EBOV-infected rhesus macaques by isolating and characterizing circulatory EVs throughout disease progression using size exclusion chromatography, nanoparticle tracking-analysis, and LC-MS/MS. While all VLPs could induce inflammatory mediators and recruit small peritoneal macrophages, pro-inflammatory cytokine and chemokine gene expression was exacerbated by the presence of GP. Further, quantification of EVs isolated from infected rhesus macaques revealed that the concentration of vesicles peaked in circulation at the terminal stage, at which time EBOV GP could be detected in host-derived exosomes. Moreover, comparative proteomics conducted across EV populations isolated from serum at various time points before and after infection revealed differences in host-derived protein content that were most significantly pronounced at the endpoint of infection, including significant expression of mediators of TLR4 signaling. These results suggest a dynamic role for EVs in the modification of disease states in the context of EBOV. Overall, our work highlights the importance of viral factors, such as the GP, and host derived EVs in the inflammatory cascade and pathogenesis of EBOV, which can be collectively further exploited for novel antiviral development.\n\nID: 38007674\nTitle: Astrocytes and Alpha-Synuclein: Friend or Foe?\nAbstract: Despite its devastating disease burden and alarming prevalence, the etiology of Parkinson's disease (PD) remains to be completely elucidated. PD is characterized by the degeneration of dopaminergic neurons in the substantia nigra pars compacta and this correlates with the accumulation of misfolded \u03b1-synuclein. While the aggregation of \u03b1-synuclein in the form of Lewy bodies or Lewy neurites is a well-established intraneuronal hallmark of the disease process, our understanding of the glial contribution to aberrant \u03b1-synuclein proteostasis is lacking. In this regard, restoring astrocyte function during early PD could offer a promising therapeutic avenue and understanding the involvement of astrocytes in handling/mishandling of \u03b1-synuclein is of particular interest. Here, we explore the growing body of scientific literature implicating aberrant astrocytic \u03b1-synuclein proteostasis with the seemingly inexorable pathological sequelae typifying PD. We also provide a perspective on how heterogeneity in the morphological relationship between astrocytes and neurons will need to be considered in the context of PD pathogenesis.\n\nID: 37884349\nTitle: Nascent A\u03b242 Fibrillization in Synaptic Endosomes Precedes Plaque Formation in a Mouse Model of Alzheimer's-like \u03b2-Amyloidosis.\nAbstract: Accumulation of amyloid-\u03b2 peptide (A\u03b2) aggregates in synapses may contribute to the profound synaptic loss characteristic of Alzheimer's disease (AD). The origin of synaptic A\u03b2 aggregates remains elusive, but loss of endosomal proteostasis may trigger their formation. In this study, we identified the synaptic compartments where A\u03b2 accumulates, and performed a longitudinal analysis of synaptosomes isolated from brains of TgCRND8 APP transgenic mice of either sex. To evaluate the specific contribution of A\u03b2-degrading protease endothelin-converting enzyme (ECE-1) to synaptic/endosomal A\u03b2 homeostasis, we analyzed the effect of partial Ece1 KO in brain and complete ECE1 KO in SH-SY5Y cells. Global inhibition of ECE family members was used to further assess their role in preventing synaptic A\u03b2 accumulation. Results showed that, before extracellular amyloid deposition, synapses were burdened with detergent-soluble A\u03b2 monomers, oligomers, and fibrils. Levels of all soluble A\u03b2 species declined thereafter, as A\u03b242 turned progressively insoluble and accumulated in A\u03b2-producing synaptic endosomal vesicles with characteristics of multivesicular bodies. Accordingly, fibrillar A\u03b2 was detected in brain exosomes. ECE-1-deficient mice had significantly increased endogenous synaptosomal A\u03b242 levels, and protease inhibitor experiments showed that, in TgCRND8 mice, synaptic A\u03b242 became nearly resistant to degradation by ECE-related proteases. Our study supports that A\u03b2 accumulating in synapses is produced locally, within endosomes, and does not require the presence of amyloid plaques. ECE-1 is a determinant factor controlling the accumulation and fibrillization of nascent A\u03b2 in endosomes and, in TgCRND8 mice, A\u03b2 overproduction causes rapid loss of A\u03b242 solubility that curtails ECE-mediated degradation.SIGNIFICANCE STATEMENT Deposition of aggregated A\u03b2 in extracellular plaques is a defining feature of AD. A\u03b2 aggregates also accumulate in synapses and may contribute to the profound synaptic loss and cognitive dysfunction typical of the disease. However, it is not clear whether synaptotoxic A\u03b2 is mainly derived from plaques or if it is produced and aggregated locally, within affected synaptic compartments. Filling this knowledge gap is important for the development of an effective treatment for AD, as extracellular and intrasynaptic pools of A\u03b2 may not be equally modulated by immunotherapies or other therapeutic approaches. In this manuscript, we provide evidence that A\u03b2 aggregates building up in synapses are formed locally, within synaptic endosomes, because of disruptions in nascent A\u03b2 proteostasis.\n\nID: 37612326\nTitle: Capsaicin binds the N-terminus of Hsp90, induces lysosomal degradation of Hsp70, and enhances the anti-tumor effects of 17-AAG (Tanespimycin).\nAbstract: Heat shock protein 90 (Hsp90) and its co-chaperones promote cancer, and targeting Hsp90 holds promise for cancer treatment. Most of the efforts to harness this potential have focused on targeting the Hsp90 N-terminus ATP binding site. Although newer-generation inhibitors have shown improved efficacy in aggressive cancers, induction of the cellular heat shock response (HSR) by these inhibitors is thought to limit their clinical efficacy. Therefore, Hsp90 inhibitors with novel mechanisms of action and that do not trigger the HSR would be advantageous. Here, we investigated the mechanism by which capsaicin inhibits Hsp90. Through mutagenesis, chemical modifications, and proteomic studies, we show that capsaicin binds to the N-terminus of Hsp90 and inhibits its ATPase activity. Consequently, capsaicin and its analogs inhibit Hsp90 ATPase-dependent progesterone receptor reconstitution in vitro. Capsaicin did not induce the HSR, instead, it promoted the degradation of Hsp70 through the lysosome-autophagy pathway. Remarkably, capsaicin did not induce degradation of the constitutively expressed cognate Hsc70, indicating selectivity for Hsp70. Combined treatments of capsaicin and the Hsp90 inhibitor 17-AAG improved the anti-tumor efficacy of 17-AAG in cell culture and tridimensional tumor spheroid growth assays using breast and prostate cancer models. Consistent with this, in silico docking studies revealed that capsaicin binding to the ATP binding site of Hsp90 was distinct from classical N-terminus Hsp90 inhibitors, indicating a novel mechanism of action. Collectively, these findings support the use of capsaicin as a chemical scaffold to develop novel Hsp90 N-terminus inhibitors as well as its ability to be a potential cancer co-therapeutic.\n\nID: 37516014\nTitle: WBP2 restrains the lysosomal degradation of GPX4 to inhibit ferroptosis in cisplatin-induced acute kidney injury.\nAbstract: Cisplatin is one of the major causes of acute kidney injury (AKI) in clinical practice, and ferroptosis is an essential form of cell death in cisplatin-induced AKI (CP-AKI). WW domain binding protein-2 (WBP2), a molecular chaperon, is involved in the progression of various malignancies, but its role in renal injuries has not been investigated. Our present study employed bioinformatics analysis to identify WBP2 as a potential modulator of AKI and ferroptosis. Preliminary laboratory investigations showed that WBP2, highly expressed in renal proximal tubular cells, was downregulated in CP-AKI. Further studies demonstrated that WBP2 decelerated ferroptosis to alleviate CP-AKI. Mechanistically, WBP2 interacted with glutathione peroxidase 4 (GPX4, a key detoxicating enzyme for ferroptosis) via its PPXY1 motif to inhibit ferroptosis. Furthermore, the in-depth investigations revealed that WBP2 competed with heat shock cognate protein 70 (HSC70) for the binding with the KEFRQ-like motifs of GPX4, leading to the deceleration of chaperon-mediated autophagy of GPX4. All in all, this study indicated the beneficial effect of WBP2 in CP-AKI and its relevance with ferroptosis, thus providing a novel insight into the modulation of ferroptosis in cisplatin-related nephropathy.\n\nID: 37503076\nTitle: Mitochondrial proteostasis mediated by CRL5 Ozz and Alix maintains skeletal muscle function.\nAbstract: High energy-demanding tissues, such as skeletal muscle, require mitochondrial proteostasis to function properly. Two quality-control mechanisms, the ubiquitin proteasome system (UPS) and the release of mitochondria-derived vesicles, safeguard mitochondrial proteostasis. However, whether these processes interact is unknown. Here we show that the E3 ligase CRL5 Ozz , a member of the UPS, and its substrate Alix control the mitochondrial concentration of Slc25A4, a solute carrier that is essential for ATP production. The mitochondria in Ozz -/- or Alix -/- skeletal muscle share overt morphologic alterations (they are supernumerary, swollen, and dysmorphic) and have abnormal metabolomic profiles. We found that CRL5 Ozz ubiquitinates Slc25A4 and promotes its proteasomal degradation, while Alix facilitates SLC25A4 loading into exosomes destined for lysosomal destruction. The loss of Ozz or Alix offsets steady-state levels of Slc25A4, which disturbs mitochondrial metabolism and alters muscle fiber composition. These findings reveal hitherto unknown regulatory functions of Ozz and Alix in mitochondrial proteostasis.\n\nID: 37178919\nTitle: Diarylheptanoid 35d overcomes EGFR TKI resistance by inducing hsp70-mediated lysosomal degradation of EGFR in EGFR-mutant lung adenocarcinoma.\nAbstract: Epidermal growth factor receptor (EGFR)-mutant lung adenocarcinoma (LUAD) patients often respond to EGFR tyrosine kinase inhibitors (TKIs) initially but eventually develop resistance to TKIs. The switch of EGFR downstream signaling from TKI-sensitive to TKI-insensitive is a critical mechanism-driving resistance to TKIs. Identification of potential therapies to target EGFR effectively is a potential strategy to treat TKI-resistant LUADs. In this study, we developed a small molecule diarylheptanoid 35d, a curcumin derivative, that effectively suppressed EGFR protein expression, killed multiple TKI-resistant LUAD cells in\u00a0vitro, and suppressed tumor growth of EGFR-mutant LUAD xenografts with variant TKI-resistant mechanisms including EGFR C797S mutations in\u00a0vivo. Mechanically, 35d triggers heat shock protein 70-mediated lysosomal pathway through transcriptional activation of several components in the pathway, such as HSPA1B, to induce EGFR protein degradation. Interestingly, higher HSPA1B expression in LUAD tumors associated with longer survival of EGFR-mutant, TKI-treated patients, suggesting the role of HSPA1B on retarding TKI resistance and providing a rationale for combining 35d with EGFR TKIs. Our data showed that combination of 35d significantly inhibits tumor reprogression on osimertinib and prolongs mice survival. Overall, our results suggest 35d as a promising lead compound to suppress EGFR expression and provide important insights into the development of combination therapies for TKI-resistant LUADs, which could have translational potential for the treatment of this deadly disease.\n\nID: 37156267\nTitle: Anisomycin inhibits Coxsackievirus B replication by promoting the lysosomal degradation of eEF1A1.\nAbstract: Group B Coxsackieviruses (CVB) are non-enveloped small RNA viruses in the genus Enterovirus, family Picornaviridae. CVB infection causes diverse conditions from common cold to myocarditis, encephalitis, and pancreatitis. No specific antiviral is available for the treatment of CVB infection. Anisomycin, a pyrrolidine-containing antibiotic and translation inhibitor, was reported to inhibit the replication of some picornaviruses. However, it is unknown if anisomycin can act as an antiviral against CVB infection. Here we observed that anisomycin showed potent inhibition on CVB type 3 (CVB3) infection with negligible cytotoxicity when applied at the early stage of virus infection. Mice infected with CVB3 showed markedly alleviated myocarditis with reduced viral replication. We found that CVB3 infection significantly increased the transcription of eukaryotic translation elongation factor 1 alpha 1 (eEF1A1). CVB3 replication was suppressed by EEF1A1 knockdown, while elevated by EEF1A1 overexpression. Similar to the effect of CVB3 infection, EEF1A1 transcription was increased in response to anisomycin treatment. However, eEF1A1 protein level was decreased with anisomycin treatment in a dose-dependent manner in CVB3-infected cells. Moreover, anisomycin promoted eEF1A1 degradation, which was inhibited by the treatment of chloroquine but not MG132. We demonstrated that eEF1A1 interacted with the heat shock cognate protein 70 (HSP70), and eEF1A1 degradation was inhibited by LAMP2A knockdown, implicating that eEF1A1 is degraded through chaperone-mediated autophagy. Taken together, we demonstrated that anisomycin, which inhibits CVB replication through promoting the lysosomal degradation of eEF1A1, could be a potential antiviral candidate for the treatment of CVB infection.\n\nID: 37019623\nTitle: Diminished Neuronal ESCRT-0 Function Exacerbates AMPA Receptor Derangement and Accelerates Prion-Induced Neurodegeneration.\nAbstract: Endolysosomal defects in neurons are central to the pathogenesis of prion and other neurodegenerative disorders. In prion disease, prion oligomers traffic through the multivesicular body (MVB) and are routed for degradation in lysosomes or for release in exosomes, yet how prions impact proteostatic pathways is unclear. We found that prion-affected human and mouse brain showed a marked reduction in Hrs and STAM1 (ESCRT-0), which route ubiquitinated membrane proteins from early endosomes into MVBs. To determine how the reduction in ESCRT-0 impacts prion conversion and cellular toxicity in vivo, we prion-challenged conditional knockout mice (male and female) having Hrs deleted from neurons, astrocytes, or microglia. The neuronal, but not astrocytic or microglial, Hrs-depleted mice showed a shortened survival and an acceleration in synaptic derangements, including an accumulation of ubiquitinated proteins, deregulation of phosphorylated AMPA and metabotropic glutamate receptors, and profoundly altered synaptic structure, all of which occurred later in the prion-infected control mice. Finally, we found that neuronal Hrs (nHrs) depletion increased surface levels of the cellular prion protein, PrPC, which may contribute to the rapidly advancing disease through neurotoxic signaling. Taken together, the reduced Hrs in the prion-affected brain hampers ubiquitinated protein clearance at the synapse, exacerbates postsynaptic glutamate receptor deregulation, and accelerates neurodegeneration.SIGNIFICANCE STATEMENT Prion diseases are rapidly progressive neurodegenerative disorders characterized by prion aggregate spread through the central nervous system. Early disease features include ubiquitinated protein accumulation and synapse loss. Here, we investigate how prion aggregates alter ubiquitinated protein clearance pathways (ESCRT) in mouse and human prion-infected brain, discovering a marked reduction in Hrs. Using a prion-infection mouse model with neuronal Hrs (nHrs) depleted, we show that low neuronal Hrs is detrimental and markedly shortens survival time while accelerating synaptic derangements, including ubiquitinated protein accumulation, indicating that Hrs loss exacerbates prion disease progression. Additionally, Hrs depletion increases the surface distribution of prion protein (PrPC), linked to aggregate-induced neurotoxic signaling, suggesting that Hrs loss in prion disease accelerates disease through enhancing PrPC-mediated neurotoxic signaling.\n\nID: 36980788\nTitle: The Pro-Tumorigenic Role of Chemotherapy-Induced Extracellular HSP70 from Breast Cancer Cells via Intratumoral Macrophages.\nAbstract: Tumor-associated macrophages (TAMs) contribute to tumor progression and chemoresistance; it is therefore important to clarify the altered functions of macrophages following chemotherapy. While extracellular heat shock protein (HSP) 70 is associated with therapeutic resistance, the effects of HSP70 on TAMs remain largely unknown. Here, we conducted in vitro experiments and immunohistochemistry in 116 breast carcinoma specimens to determine whether the secretion of HSP70 from breast cancer cells following chemotherapy affects macrophage function. It was revealed that the interaction of epirubicin (EPI)-exposed breast cancer cells with macrophages enhanced tumor progression, and EPI promoted the secretion of extracellular HSP70 from breast cancer cells. The expression of pro-tumorigenic macrophage marker CD163 was decreased in macrophages treated with a conditioned medium (CM) from HSP70-silenced breast cancer cells. Breast cancer cells treated with CM from HSP70-silenced breast cancer cells showed decreased expression of transforming growth factor (TGF)-\u03b2, and the pro-tumorigenic effects of macrophages were impaired when TGF-\u03b2 signaling was inhibited. Immunohistochemistry demonstrated that HSP70 served as a poor prognostic factor in conjunction with macrophage infiltration. It was therefore concluded that extracellular HSP70 levels increased following chemotherapy and enhanced the pro-tumorigenic effects of TAMs, either directly or indirectly, by regulating TGF-\u03b2 expression in breast cancer cells.\n\nID: 36968202\nTitle: Purriato is a conserved small open reading frame gene that interacts with the CASA pathway to regulate muscle homeostasis and epithelial tissue growth in Drosophila.\nAbstract: Recent advances in proteogenomic techniques and bioinformatic pipelines have permitted the detection of thousands of translated small Open Reading Frames (smORFs), which contain less than 100 codons, in eukaryotic genomes. Hundreds of these actively translated smORFs display conserved sequence, structure and evolutionary signatures indicating that the translated peptides could fulfil important biological roles. Despite their abundance, only tens of smORF genes have been fully characterised; these act mainly as regulators of canonical proteins involved in essential cellular processes. Importantly, some of these smORFs display conserved functions with their mutations being associated with pathogenesis. Thus, investigating smORF roles in Drosophila will not only expand our understanding of their functions but it may have an impact in human health. Here we describe the function of a novel and essential Drosophila smORF gene named purriato (prto). prto belongs to an ancient gene family whose members have expanded throughout the Protostomia clade. prto encodes a transmembrane peptide which is localized in endo-lysosomes and perinuclear and plasma membranes. prto is dynamically expressed in mesodermal tissues and imaginal discs. Targeted prto knockdown (KD) in these organs results in changes in nuclear morphology and endo-lysosomal distributions correlating with the loss of sarcomeric homeostasis in muscles and reduction of mitosis in wing discs. Consequently, prto KD mutants display severe reduction of motility, and shorter wings. Finally, our genetic interaction experiments show that prto function is closely associated to the CASA pathway, a conserved mechanism involved in turnover of mis-folded proteins and linked to muscle dystrophies and neurodegenerative diseases. Thus, this study shows the relevance of smORFs in regulating important cellular functions and supports the systematic characterisation of this class of genes to understand their functions and evolution.\n\nID: 36805906\nTitle: HSP70 regulates lipid metabolism of decidual macrophages to maintain normal pregnancy.\nAbstract: Dysfunction of decidual macrophages (dMs) are closely associated with recurrent pregnancy loss (RPL) which brings great suffering to patients. Metabolism is essential for regulating macrophage function. Identifying molecules that regulate metabolism and function of dMs is important to revealing the pathogenesis of RPL. Single-cell sequencing data of decidual immune cells from control and RPL patients were downloaded from the GSA database and converted into feature-barcode matrices by Cell Ranger. After quality control, removal of double cell and clustering of all cells, 3579 macrophages were extracted for normalisation, scaling and re-clustering. Function and metabolism analyses were performed by R packages AddMoudleScore, scMetabolism and AUCell. Metabolism clustering based on metabolism-related genes to clarify the metabolic characteristics of macrophages clusters. These results indicated that macrophage characterised by lipid metabolism were reduced in RPL and differential expression genes analysis found that HSP70 was significantly decreased in the RPL group. Furthermore, immunofluorescence staining demonstrated that HSP70 was significantly downregulated in dMs of RPL patients compared to controls. In conclusion, HSP70 may maintain normal pregnancy by regulating lipid metabolism of dMs. This study provides new insights into the molecular mechanisms regulating the function of dMs and provides a theoretical basis for the development of new therapies for RPL.\n\nID: 36763514\nTitle: Chaperoning the driver of filovirus egress to a dead end.\nAbstract: Ebola virus (EBOV) and Marburg virus (MARV) are zoonotic, virulent pathogens that cause sporadic and global outbreaks of severe hemorrhagic fever. Reemergence of these filoviruses remains a global public health threat, highlighting the need for novel countermeasures to control and treat future disease outbreaks. The EBOV VP40 matrix protein drives virion assembly and egress. We recently reported that BAG3 and HSPA/HSP70, two central components of chaperone-assisted selective autophagy (CASA), target VP40 for autophagic sequestration and degradation, thereby inhibiting virus egress and spread. In addition, we found that expression of the EBOV glycoprotein (GP) activates MTORC1, the gateway regulator of autophagy. Notably, pharmacological suppression of MTORC1 signaling by rapamycin activates autophagy and blocks filovirus egress. These findings highlight the MTORC1-CASA axis as a regulator of filovirus egress and suggest new opportunities for antiviral development and intervention.\n\nID: 36743458\nTitle: DNAJB12 and Hsp70 Mediate Triage of Misfolded Membrane Proteins for Proteasomal versus Lysosomal Degradation.\nAbstract: The endoplasmic reticulum (ER) fills the cell with a continuous network of sealed membrane tubules and sheets. The ER is subdivided into microdomains mediating one-third of total protein biosynthesis, oxidative protein folding, secretion, protein quality control, calcium signaling, marcoautophagy/autophagy, stress sensing, and apoptosis. Defects in ER-calcium homeostasis underlie several diseases. Damage to the ER by misfolded membrane proteins is suppressed by specific HSPA/Hsp70 and DNAJ/Hsp40 chaperone pairs that select intermediates for ubiquitination and ER-associated degradation (ERAD) via the proteasome. The ER-transmembrane Hsp40 chaperone DNAJB12 and HSPA/Hsp70 also target toxic intermediates of misfolded membrane proteins for ER-associated autophagy (ERAA). DNAJB12-HSPA/Hsp70 maintain membrane protein degradation intermediates in detergent-soluble and degradation-competent states. DNAJB12-HSPA/Hsp70 also interact with the autophagy initiation kinase ULK1 on ER tubules containing ERAD-resistant misfolded membrane proteins (ERAD-RMPs). Omegasomes are ER microdomains where the autophagosome precursor or phagophore (PG) forms. ER tubules loaded with ERAD-RMPs enter omegasomes where they are converted into ER-connected PG (ER-PG). The Atg8 (autophagy related 8)-family member GABARAP (GABA type A receptor-associated protein) facilitates transfer of ERAD-RMPs from ER-PGs to autolysosomes (AL) that dock transiently with omegasomes. This article describes a model for DNAJB12-HSPA/Hsp70 action during the conformation-dependent triage in the ER of misfolded membrane proteins for folding versus proteasomal or AL degradation.\n\nID: 36598950\nTitle: Chaperone-assisted selective autophagy targets filovirus VP40 as a client and restricts egress of virus particles.\nAbstract: The filovirus VP40 protein directs virion egress, which is regulated either positively or negatively by select VP40-host interactions. We demonstrate that host BAG3 and HSP70 recognize VP40 as a client and inhibit the egress of VP40 virus-like particles (VLPs) by promoting degradation of VP40 via Chaperone-assisted selective autophagy (CASA). Pharmacological inhibition of either the early stage formation of the VP40/BAG3/HSP70 tripartite complex, or late stage formation of autolysosomes, rescued VP40 VLP egress back to WT levels. The mechanistic target of rapamycin complex 1 (mTORC1) is a master regulator of autophagy, and we found that surface expression of EBOV GP on either VLPs or an infectious VSV recombinant virus, activated mTORC1. Notably, pharmacological suppression of mTORC1 signaling by rapamycin activated CASA in a BAG3-dependent manner to restrict the egress of both VLPs and infectious EBOV in Huh7 cells. In sum, our findings highlight the involvement of the mTORC1/CASA axis in regulating filovirus egress.\n\nID: 36581212\nTitle: Extracellular chaperone networks and the export of J-domain proteins.\nAbstract: An extracellular network of molecular chaperones protects a diverse array of proteins that reside in or pass through extracellular spaces. Proteins in the extracellular milieu face numerous challenges that can lead to protein misfolding and aggregation. As a checkpoint for proteins that move between cells, extracellular chaperone networks are of growing clinical relevance. J-domain proteins (JDPs) are ubiquitous molecular chaperones that are known for their essential roles in a wide array of fundamental cellular processes through their regulation of heat shock protein 70s. As the largest molecular chaperone family, JDPs have long been recognized for their diverse functions within cells. Some JDPs are elegantly selective for their \"client proteins,\" some do not discriminate among substrates and others act cooperatively on the same target. The realization that JDPs are exported through both classical and unconventional secretory pathways has fueled investigation into the roles that JDPs play in protein quality control and intercellular communication. The proposed functions of exported JDPs are diverse. Studies suggest that export of DnaJB11 enhances extracellular proteostasis, that intercellular movement of DnaJB1 or DnaJB6 enhances the proteostasis capacity in recipient cells, whereas the import of DnaJB8 increases resistance to chemotherapy in recipient cancer cells. In addition, the export of DnaJC5 and concurrent DnaJC5-dependent ejection of dysfunctional and aggregation-prone proteins are implicated in the prevention of neurodegeneration. This review provides a brief overview of the current understanding of the extracellular chaperone networks and outlines the first wave of studies describing the cellular export of JDPs.\n\nID: 36520313\nTitle: CHIP: A Co-chaperone for Degradation by the Proteasome and Lysosome.\nAbstract: Protein homeostasis relies on a balance between protein folding and protein degradation. Molecular chaperones like Hsp70 and Hsp90 fulfill well-defined roles in protein folding and conformational stability via ATP-dependent reaction cycles. These folding cycles are controlled by associations with a cohort of non-client protein co-chaperones, such as Hop, p23, and Aha1. Pro-folding co-chaperones facilitate the transit of the client protein through the chaperone-mediated folding process. However, chaperones are also involved in proteasomal and lysosomal degradation of client proteins. Like folding complexes, the ability of chaperones to mediate protein degradation is regulated by co-chaperones, such as the C-terminal Hsp70-binding protein (CHIP/STUB1). CHIP binds to Hsp70 and Hsp90 chaperones through its tetratricopeptide repeat (TPR) domain and functions as an E3 ubiquitin ligase using a modified RING finger domain (U-box). This unique combination of domains effectively allows CHIP to network chaperone complexes to the ubiquitin-proteasome and autophagosome-lysosome systems. This chapter reviews the current understanding of CHIP as a co-chaperone that switches Hsp70/Hsp90 chaperone complexes from protein folding to protein degradation.\n\nID: 36448045\nTitle: Muscle-to-Brain Signaling Via Myokines and Myometabolites.\nAbstract: Skeletal muscle health and function are important determinants of systemic metabolic homeostasis and organism-wide responses, including disease outcome. While it is well known that exercise protects the central nervous system (CNS) from aging and disease, only recently this has been found to depend on the endocrine capacity of skeletal muscle. Here, we review muscle-secreted growth factors and cytokines (myokines), metabolites (myometabolites), and other unconventional signals (e.g. bioactive lipid species, enzymes, and exosomes) that mediate muscle-brain and muscle-retina communication and neuroprotection in response to exercise and associated processes, such as the muscle unfolded protein response and metabolic stress. In addition to impacting proteostasis, neurogenesis, and cognitive functions, muscle-brain signaling influences complex brain-dependent behaviors, such as depression, sleeping patterns, and biosynthesis of neurotransmitters. Moreover, myokine signaling adapts feeding behavior to meet the energy demands of skeletal muscle. Contrary to protective myokines induced by exercise and associated signaling pathways, inactivity and muscle wasting may derange myokine expression and secretion and in turn compromise CNS function. We propose that tailoring muscle-to-CNS signaling by modulating myokines and myometabolites may combat age-related neurodegeneration and brain diseases that are influenced by systemic signals.\n\nID: 36436593\nTitle: PTEN Deficiency Facilitates Exosome Secretion and Metastasis in Cholangiocarcinoma by Impairing TFEB-mediated Lysosome Biogenesis.\nAbstract: In eukaryotes, the ubiquitin-proteasome system and the autophagy-lysosome pathway are essential for maintaining cellular proteostasis and associated with cancer progression. Our previous studies have demonstrated that phosphatase and tensin homolog (PTEN), one of the most frequently mutated genes in human cancers, limits proteasome abundance and determines chemosensitivity to proteasome inhibitors in cholangiocarcinoma (CCA). However, whether PTEN regulates the lysosome pathway remains unclear. We tested the effects of PTEN on lysosome biogenesis and exosome secretion using loss- and gain-of-function strategies in CCA cell lines. Using in\u00a0vitro dephosphorylation assays, we explored the regulatory mechanism between PTEN and the key regulator of lysosome biogenesis, transcription factor EB (TFEB). Using the migration assays, invasion assays, and trans-splenic liver metastasis mouse models, we evaluated the function of PTEN deficiency, TFEB-mediated lysosome biogenesis, and exosome secretion on tumor metastasis. Moreover, we investigated the clinical significance of PTEN expression and exosome secretion by retrospective analysis. PTEN facilitated lysosome biogenesis and acidification through its protein phosphatase activity to dephosphorylate TFEB at Ser211. Notably, PTEN deficiency increased exosome secretion by reducing lysosome-mediated degradation of multi-vesicular bodies, which further facilitated the proliferation and invasion of CCA. TFEB agonist curcumin analog C1 restrained the metastatic phenotype caused by PTEN deficiency in mouse models, and we highlighted the correlation between PTEN deficiency and exosome secretion in clinical cohorts. In CCA, PTEN deficiency impairs lysosome biogenesis to facilitate exosome secretion and cancer metastasis in a TFEB phosphorylation-dependent manner.\n\nID: 36157498\nTitle: Chaperone-assisted E3 ligase CHIP: A double agent in cancer.\nAbstract: The carboxy-terminus of Hsp70-interacting protein (CHIP) is a ubiquitin ligase and co-chaperone belonging to Ubox family that plays a crucial role in the maintenance of cellular homeostasis by switching the equilibrium of the folding-refolding mechanism towards the proteasomal or lysosomal degradation pathway. It links molecular chaperones viz. HSC70, HSP70 and HSP90 with ubiquitin proteasome system (UPS), acting as a quality control system. CHIP contains charged domain in between N-terminal tetratricopeptide repeat (TPR) and C-terminal Ubox domain. TPR domain interacts with the aberrant client proteins via chaperones while Ubox domain facilitates the ubiquitin transfer to the client proteins for ubiquitination. Thus, CHIP is a classic molecule that executes ubiquitination for degradation of client proteins. Further, CHIP has been found to be indulged in cellular differentiation, proliferation, metastasis and tumorigenesis. Additionally, CHIP can play its dual role as a tumor suppressor as well as an oncogene in numerous malignancies, thus acting as a double agent. Here, in this review, we have reported almost all substrates of CHIP established till date and classified them according to the hallmarks of cancer. In addition, we discussed about its architectural alignment, tissue specific expression, sub-cellular localization, folding-refolding mechanisms of client proteins, E4 ligase activity, normal physiological roles, as well as involvement in various diseases and tumor biology. Further, we aim to discuss its importance in HSP90 inhibitors mediated cancer therapy. Thus, this report concludes that CHIP may be a promising and worthy drug target towards pharmaceutical industry for drug development.\n\nID: 36139453\nTitle: Cell Surface Hsp90- and \u03b1M\u03b22 Integrin-Mediated Uptake of Bacterial Flagellins to Activate Inflammasomes by Human Macrophages.\nAbstract: All-trans retinoic acid (ATRA) is an active metabolite of vitamin A, which plays an important role in the immune function. Here, we demonstrated that ATRA induces the heat shock protein (Hsp) 90 complex on the surface of THP-1 macrophages, which facilitates the internalization of exogenous bacterial flagellins to activate the inflammasome response. Mass spectrometric protein identification and co-immunoprecipitation revealed that the Hsp90 homodimer interacts with both Hsp70 and \u03b1M\u03b22 integrin. ATRA-induced complex formation was dependent on the retinoic acid receptor (RAR)/retinoid X receptor (RXR) pathway and intracellular calcium level and was essential for triggering the internalization of bacterial flagellin, which was clathrin dependent. Notably, in this process, \u03b1M\u03b22 integrin was found to act as a carrier to deliver flagellin to the cytosol to activate the inflammasome, leading to caspase-1 activity and secretion of interleukin (IL)-1\u03b2. Our study provides new insights into the underlying molecular mechanism by which exogenous bacterial flagellins are delivered into host cells without a bacterial transport system, as well as the mechanism by which vitamin A contributes to enhancing the human macrophage function to detect and respond to bacterial infection.\n\nID: 42195849\nTitle: Scallion White and Ginger Extracts Alleviate Stress-Induced Muscle Quality Deterioration in Crucian Carp During Transportation.\nAbstract: This study evaluated the effects of scallion white and ginger extracts on stress indicators, gene expression, tissue structure, and muscle quality in crucian carp during transportation. Compared with the control group, ginger extract effectively alleviated long-term transportation stress (48 h), as evidenced by lower levels of glucose and lactate dehydrogenase activity, along with reduced pathological damage in gill, liver, and muscle tissues. Consequently, muscle quality parameters including shear force, glycogen content, and inosine monophosphate levels were notably improved. These improvements were associated with the suppression of heat shock responses, inflammation, and apoptosis, supported by the downregulation of hsp70, il-6, caspase 3, caspase 8 and bax gene expression. Similar trends were observed in the scallion white extract group, though its anti-stress effects and muscle quality enhancement were comparatively weaker. The findings suggest that natural extracts offer a promising approach to mitigating stress and improving muscle quality during live fish transportation.\n\nID: 41653632\nTitle: Growth performance and antioxidant response of broiler chicken fed oxidized lipids with or without phytogenic feed additives.\nAbstract: The aim of this study was to test the in vivo antioxidant capacity in broilers of two phytogenic additives, one derived from olive pomace (OE) and an encapsulated product based on Capsicum sp., black pepper, and ginger (SPICY), in a challenge using oxidized lipids in the feed. A total of 720 one-day-old male Cobb 500 were allocated to 72 pens (8 treatments, 9 replicates, 10 birds/replicate). The treatments were arranged in a 2 \u00d7 2 \u00d7 2 factorial, the factors being: fat source (4% soybean oil or 4% peroxidized soybean oil); SPICY (0 or 250 ppm); and OE (0 or 3077 ppm). From 1 to 21 days (global period) no significant differences were observed on performance. Broilers fed peroxidized oil showed higher plasma ferric reducing antioxidant power (FRAP; P < 0.05) values and higher catalase (CAT) activity compared to those fed fresh oil except in those birds fed the OE which remained constant with both oil sources (P < 0.05 for the interaction). Broilers fed OE showed a significant lower CAT gene expression in the liver (P < 0.05). Moreover, the heat shock protein 70 (HSP70) gene expression was lower in birds fed fresh oil and OE compared to those fed fresh oil without OE but higher in birds fed peroxidized oil and OE compared to those fed peroxidized oil without OE (P < 0.05 for the interaction). By contrast, broilers fed SPICY upregulated CAT (P < 0.05) and downregulated HSP70 (P < 0.05) gene expression in the liver compared to those not supplemented with SPICY. In conclusion, feeding broilers with peroxidized soybean oil from 1 to 21 days of age did not affect the productive parameters. However, the presence of lipid peroxidation products in the feed triggered both non-enzymatic and enzymatic antioxidant responses to maintain the oxidant/antioxidant balance. In the case of birds fed the OE, the enzymatic antioxidant response was more attenuated, indicating a better control of oxidative stress, likely mediated by HSP70.\n\nID: 41317750\nTitle: Design, synthesis, and activity evaluation of alpinetin derivatives as potential anti-liver cancer drugs.\nAbstract: Liver cancer represents a major global health challenge, significantly impacting populations both in China and worldwide. Alpinetin (ALP), extracted from the ginger plant cardamom, has been shown to possess significant anti-liver cancer activity. However, its solubility and mechanism of action remain unclear, hindering its further development and application. Heat shock protein 70 (HSP70) has been proven to be a potential target for the treatment of liver cancer. Based on rational drug design principles, ALP was conjugated with specific pharmacophores through oxime linkages to yield novel compounds, aiming to reduce toxicity and enhanced activity. Thus, representative compounds 1a and 1b were obtained. Then, the preliminary mechanism of action was further investigated. Western blot analysis results indicate that compounds 1a and 1b could inhibit the expression of HSP70 protein in HepG2 liver cancer cells. Cell apoptosis data indicate that the synthesized compounds exert anticancer activity by inducing apoptosis. Therefore, this study suggests that ALP and its derivatives may become promising drugs for exerting anti liver cancer effects by regulating the expression of HSP70 protein.\n\nID: 40869009\nTitle: Mitigating Effect of Ginger Extract on Survival Rate and Muscle Quality of Crucian Carp (Carassius auratus) Under Transportation Stress.\nAbstract: This study evaluated the effects of ginger extract, applied via four methods-direct addition, microencapsulation, and combinations with NaCl or eugenol-on stress responses and muscle quality in crucian carp during transportation. Among the treatments, microcapsules and the eugenol compound showed the best results, each achieving a 50% survival rate after 72 h. The microcapsule group provided prolonged antioxidant protection, stabilized water quality, reduced cortisol levels, suppressed pro-apoptotic gene expression (hsp70, hsp90, il-6, caspase 3, caspase 8, and bax), while upregulating the anti-apoptotic gene bcl-2. These alterations contributed to lower lactic acid accumulation and glycogen consumption, enhanced muscle shear force, reduced drip loss, and improved structural integrity of the gill, liver, and muscle tissues. The eugenol group effectively limited ammonia nitrogen accumulation, decreased glutathione peroxidase activity, and downregulated stress and apoptosis-related genes (bax, caspase 3, and caspase 9), resulting in reduced tissue damage. In contrast, the NaCl compound group accelerated water quality deterioration, increased TDS (total dissolved solids), lowered dissolved oxygen, and weakened stress resistance, leading to more severe tissue damage. Overall, microencapsulation or eugenol co-application were the most effective strategies for enhancing survival and maintaining muscle quality during transportation.\n\nID: 40150337\nTitle: Effects of Olive Pomace and Spice Extracts on Performance and Antioxidant Function in Broiler Chickens.\nAbstract: This research aimed to evaluate the effects of an olive pomace extract (OE) and a fat-encapsulated extract composed of a blend of oleoresins from Capsicum sp., black pepper, and ginger (SPICY) on broiler chicken performance and antioxidant function. In total, 640 1-day-old male chicks were randomly assigned to five experimental diets (eight replicates/treatment, 16 birds/replicate). Diets included a basal diet with no added vitamin E (NC), NC plus 100 ppm of vitamin E (PC), NC plus 1250 ppm of OE, NC plus 250 ppm of (SPICY), and NC plus 1250 ppm OE plus 250 ppm of SPICY (SPIOE). Phytogenic additives were supplied by Lucta S.A., Spain. Compared to the NC, the PC significantly (p < 0.05) increased ADG from 8 to 14 days of age, with both OE and SPICY showing intermediate values between both controls. At the end of this trial, at 35 days of age, a significant (p < 0.05) increase in plasma GPx activity was observed in PC-fed birds compared to the NC, with no effects of malonyl dialdehyde (MDA) and total antioxidant capacity. Birds fed the OE and SPICY displayed intermediate values of GPx activity compared to both controls. The expression of heat shock protein 70 (HSP70) and glutathione S-Transferase Alpha 4 (GSTA4) was significantly lower (p < 0.05) in the jejunal mucosa of birds fed the OE compared to the NC. Moreover, the expression of HSP70 was significantly lower (p < 0.05) in birds fed the OE compared to SPICY but was not significantly different compared to the blend of both extracts (SPIOE). In conclusion, OE and SPICY were useful in maintaining growth performance in no vit E-supplemented diets, particularly in the case of OE mediated by its antioxidant action through HSP70.\n\nID: 39346697\nTitle: Effects of turmeric, ginger, cinnamon, and garlic essential oils on HSP70, NF\u03baB, oxidative DNA damage, inflammatory cytokines, and oxidative markers in broiler chickens.\nAbstract: In recent years, the use of natural bioactive compounds derived from spices has garnered significant interest in poultry production due to their potential to modulate immune responses and oxidative stress. An investigation into the roles of spices essential oils (EO) on inflammatory cytokines, HSP70 and oxidative markers of broiler chickens was conducted in this study. Four spices consisting of garlic, ginger, turmeric, and cinnamon were processed to obtain their respective EO. Two hundred 1-d-old arbo acre broilers were allotted to 5 treatments consisting of B1 (control), B2 (garlic EO), B3 (ginger EO), B4 (Turmeric EO), and B5 (cinnamon EO), with EOs administered to drinking water at 30% (v/v) in a 49-d trial. Blood was sampled for assessment of hematological parameters, and serum obtained were assayed for inflammatory cytokines, antioxidant activities, nuclear factor kappa B (NF\u03baB), 8-hydroxydeoxyguanosine (8-OHdG), and heat shock protein 70 (HSP70) levels using standard procedures. Results obtained revealed that cinnamon EO enhanced erythrocytic indices, leukocyte profile, catalase, glutathione peroxidase and interleukin 10, lowers interleukin 1 beta (IL-1\u03b2) and interferon gamma (IFN-\u03b3), enhanced HSP70 and higher 8-OHdG levels in chicken. Garlic EO enhanced monocytes and superoxide dismutase, while reduced IFN-\u03b3 and HSP70, but increased IL-1\u03b2 and tumor necrosis factor alpha (TNF-\u03b1) NF\u03baB in broiler chickens. Ginger EO also enhanced erythrocytic indices, total antioxidant activity, lowered IFN-\u03b3 and lipid peroxidation, while turmeric EO enhanced total antioxidant activity, catalase and lowered IFN-\u03b3 and increased 8ohdg in broiler chickens. In conclusion, this study revealed that ginger and turmeric EO were more beneficial in preventing oxidative DNA damage, cinnamon EO enhanced serum oxidative status and lowered pro-inflammatory cytokines, while garlic EO reduced HSP70 in broiler chickens.\n\nID: 33005764\nTitle: Priming of intestinal cytoprotective genes and antioxidant capacity by dietary phytogenic inclusion in broilers.\nAbstract: The potential of a phytogenic premix (PP) based on ginger, lemon balm, oregano and thyme to stimulate the expression of cytoprotective genes at the broiler gut level was evaluated in this study. In particular, the effects of PP inclusion levels on a selection of genes related to host protection against oxidation (catalase [CAT], superoxide dismutase 1 [SOD1], glutathione peroxidase 2 [GPX2], heme oxygenase 1 [HMOX1], NAD(P)H quinone dehydrogenase 1 [NQO1], nuclear factor (erythroid-derived 2)-like 2 [Nrf2] and kelch like ECH associated protein 1 [Keap1]), stress (heat shock 70\u00a0kDa protein 2 [HSP70] and heat shock protein 90 alpha family class A member 1 [HSP90]) and inflammation (nuclear factor kappa B subunit 1 [NF-\u03baB1], Toll-like receptor 2 family member B (TLR2B) and Toll-like receptor 4 [TLR4]) were profiled along the broiler intestine. In addition, broiler intestinal segments were assayed for their total antioxidant capacity (TAC). Depending on PP inclusion level (i.e. 0, 750, 1,000 and 2,000\u00a0mg/kg diet) in the basal diets, 1-d-old Cobb broiler chickens (n\u00a0=\u00a0500) were assigned into the following 4 treatments: CON, PP-750, PP-1000 and PP-2000. Each treatment had 5 replicates of 25 chickens with ad libitum access to feed and water. Data were analyzed by ANOVA and means compared using Tukey's honest significant difference (HSD) test. Polynomial contrasts tested the linear and quadratic effect of PP inclusion levels. Inclusion of PP increased (P\u00a0\u2264\u00a00.05) the expression of cytoprotective genes against oxidation, except CAT. In particular, the cytoprotective against oxidation genes were up-regulated primarily in the duodenum and the ceca and secondarily in the jejunum. Most of the genes were up-regulated in a quadratic manner with increasing PP inclusion level with the highest expression levels noted in treatments PP-750 and PP-1000 compared to CON. Similarly, intestinal TAC was higher in PP-1000 in the duodenum (P\u00a0=\u00a00.011) and the ceca (P\u00a0=\u00a00.050) compared to CON. Finally, increasing PP inclusion level resulted in linearly reduced (P\u00a0\u2264\u00a00.05) expression of NF-\u03baB1, TLR4 and HSP70, the former in the duodenum and the latter 2 in the ceca. Overall, PP inclusion consistently up-regulated cytoprotective genes and down-regulated stress and inflammation related ones. The effect is dependent on PP inclusion level and the intestinal site. The potential of PP to beneficially prime bird cytoprotective responses merit further investigation under stress-challenge conditions.\n\nID: 31143238\nTitle: Effect of herbal antioxidant-rich formula on improvement of antioxidant defense system and heat shock protein-70 expression in recreational female athletes: A randomized controlled trial.\nAbstract: The aim of the present study was to evaluate the effect of natural antioxidant formula (blend of herbs: ginger root, cinnamon bark and raw almond fruit powder, rosemary leaf powder, and honey) on oxidative status, antioxidant enzyme activity, and relative heat shock protein (HSP-70) expression in recreational female athletes. Eighteen female participants trained for 4 weeks and randomly received either antioxidant formula (FormEX) (n = 8) or placebo (PlcEX) (n = 10) in a randomized controlled trial. Blood samples were obtained 1-h before, 1 h and 24 h postexercise to measure malondialdehyde (MDA), total antioxidant capacity (TAC), superoxide dismutase (SOD), glutathione peroxidases (GPx), and HSP70 mRNA expression. Data analysis was performed using 2 (treatment = grouping factor) \u00d76 (time = within-factor) repeated measurements analysis of variance or generalized estimating equations (GEE) test. We used the independent t-test to evaluate any significant differences for real-time polymerase chain reaction data. Antioxidant formula increased the relative HSP-70 mRNA expression more than Plc-EX group in all time points (P = 0.001). The time main effect was significant with regard to TAC and SOD concentrations (P = 0.001 and 0.002, respectively). However, there were no statistically significant differences between groups for TAC, SOD, and MDA (P = 0.25, 0.06, and 0.38, respectively). Neither the time main effect for MDA nor time and intervention interaction was not statistically significant for MDA, TAC, and SOD (P = 0.19, 0.13, and 0.10, respectively). GEE results for GPx showed that there were no significant differences between the groups (P = 0.11). The results presented herein revealed that natural antioxidant rich formula had variable effects on oxidative status. However, in contrast to many antioxidant supplements, this formulation increases the HSP-70 mRNA expression which might improve the antioxidant ability of cells in the long-term period and exercise-induced adaptation.\n\nID: 25652595\nTitle: The postulated mechanism of the protective effect of ginger on the aspirin induced gastric ulcer: Histological and immunohistochemical studies.\nAbstract: There are many available drugs for treating gastric ulcer, but they have various side effects. Ginger is a folk, herbal medicine, which is used for treatment of various diseases including gastric ulcer. This study investigates the possible mechanism of the protective effect of ginger on aspirin induced gastric ulcer. Forty adult male albino rats were randomized into four groups (10 animal per each group) and orally received the followings once daily for 5 days: Group I: 3 ml of 1% carboxymethyl cellulose; Group II: ginger powder (200 mg/kg body weight) suspended in 3 mL of 1% carboxymethylcellulose; Group III: aspirin (400 mg/kg body weight) suspended in 3 ml of 1% carboxymethylcellulose in water. Group IV: ginger and 30 minutes later, received aspirin suspended in 1% carboxymethylcellulose, in similar doses as received in groups II and III. On day 6, rats were sacrificed. The animals were anesthetized and the stomach was removed for the macroscopic, histological (Haematoxylin & Eosin and Periodic Acid Shiff) and immunohistochemical investigations (Bax, inducible nitric oxide synthase and heat shock protein 70). Aspirin induced a significant increase of the macroscopic ulcer score, shed and disrupted epithelium, mucosal hemorrhage, submucosal edema and leukocyte infiltration, loss of the mucus of the mucosal surface significantly increased expression of apoptosis regulator Bax, inducible nitric oxide synthase (iNOS) and heat shock protein 70 (HSP70). Ginger ameliorated the histological changes by reducing Bax and iNOS and increasing HSP70 expressions.\n\nID: 21864631\nTitle: Anti-inflammatory effects of [6]-shogaol: potential roles of HDAC inhibition and HSP70 induction.\nAbstract: Ginger extracts have been reported to have anti-inflammatory, anti-oxidant, and anti-cancer effects. [6]-shogaol is one of the most bioactive components of ginger rhizomes. This study assessed the [6]-shogaol's ability to protect cultured primary rat astrocytes against lipopolysaccharide (LPS)-induced inflammation. [6]-shogaol was shown to suppress the release of pro-inflammatory cytokines and decreased the level of inducible nitric oxide syntheses (iNOS), cyclooxygenase-2 (COX-2), and phospho-NF-kB in LPS-treated astrocytes. Furthermore, [6]-shogaol treatment markedly up-regulated histone H3 acetylation and suppressed histone deacetylase (HDAC)1 expression. In addition, [6]-shogaol treatment also increased the expression of heat-shock protein (HSP)70. The neuroprotective, neurotrphic, and anti-inflammatory properties of [6]-shogaol may be translated to improvements in neurological performance. [6]-Shogaol's ability to inhibit HDAC was comparable to that of commonly used HDAC inhibitors Trichostatin A and MS275. Taken together, our results suggest that [6]-shogaol can significantly attenuate a variety of neuroinflammatory responses by inducing HSP70, that is associated with HDAC inhibition in cortical astrocytes.\n\nID: 9583595\nTitle: Early modification of host cell gene expression induced by HIV-1.\nAbstract: Characterization of the effects of infection with HIV-1 on cellular gene expression. Differential RNA display was applied to compare uninfected and HIV-1LAI-infected CEM cells 24 h post-inoculation. Differential bands were selected, cloned and several clones per band were sequenced. RNase protection assay was used to confirm differential display findings in HIV-1LAI-infected CEM cells as well as in another T-cell line (H9) infected with a different strain (HIV-1 SF33) Twelve differentially expressed bands, six up- and six downregulated in HIV-infected cells compared with controls, were selected. Four of the six upregulated bands were HIV transcripts. RNase protection assay of the remaining eight bands confirmed differential expression of four genes, including induction of a mariner transposase and moesin as well as suppression of alpha-nascent polypeptide-associated complex and mitochondrial heat shock protein 75 in HIV-1-infected cell cultures. Furthermore, a significant increase of glioma pathogenesis-related protein was found by RNase protection assay. Based on this initial limited differential display analysis, it was estimated that expression of 3% of the host genes was altered by HIV-1. Amongst the identified gene modifications, the induction of a mariner transposase may alter cellular gene expression itself, whilst the enhanced expression of glioma pathogenesis-related protein suggests a role in the host cell response to viral infection. The increase in moesin may facilitate viral budding and uptake. Furthermore, the suppression of alpha-nascent polypeptide-associated complex may promote translocation of HIV-1 polypeptides into the endoplasmic reticulum, whereas the downregulation of mitochondrial heat shock protein 75 may contribute to a cytopathic effect on mitochondria and possibly impairs antigen presentation.\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.

The ER is subdivided into microdomains mediating one-third of total protein biosynthesis, oxidative protein folding, secretion, protein quality control, calcium signaling, marcoautophagy/autophagy, stress sensing, and apoptosis. Defects in ER-calcium homeostasis underlie several diseases. Damage to the ER by misfolded membrane proteins is suppressed by specific HSPA/Hsp70 and DNAJ/Hsp40 chaperone pairs that select intermediates for ubiquitination and ER-associated degradation (ERAD) via the proteasome. The ER-transmembrane Hsp40 chaperone DNAJB12 and HSPA/Hsp70 also target toxic intermediates of misfolded membrane proteins for ER-associated autophagy (ERAA). DNAJB12-HSPA/Hsp70 maintain membrane protein degradation intermediates in detergent-soluble and degradation-competent states. DNAJB12-HSPA/Hsp70 also interact with the autophagy initiation kinase ULK1 on ER tubules containing ERAD-resistant misfolded membrane proteins (ERAD-RMPs). Omegasomes are ER microdomains where the autophagosome precursor or phagophore (PG) forms. ER tubules loaded with ERAD-RMPs enter omegasomes where they are converted into ER-connected PG (ER-PG).

WW domain binding protein-2 (WBP2), a molecular chaperon, is involved in the progression of various malignancies, but its role in renal injuries has not been investigated. Our present study employed bioinformatics analysis to identify WBP2 as a potential modulator of AKI and ferroptosis. Preliminary laboratory investigations showed that WBP2, highly expressed in renal proximal tubular cells, was downregulated in CP-AKI. Further studies demonstrated that WBP2 decelerated ferroptosis to alleviate CP-AKI. Mechanistically, WBP2 interacted with glutathione peroxidase 4 (GPX4, a key detoxicating enzyme for ferroptosis) via its PPXY1 motif to inhibit ferroptosis. Furthermore, the in-depth investigations revealed that WBP2 competed with heat shock cognate protein 70 (HSC70) for the binding with the KEFRQ-like motifs of GPX4, leading to the deceleration of chaperon-mediated autophagy of GPX4. All in all, this study indicated the beneficial effect of WBP2 in CP-AKI and its relevance with ferroptosis, thus providing a novel insight into the modulation of ferroptosis in cisplatin-related nephropathy.\n --- END ACTUAL ABSTRACT FOR 37516014 ---\n\n- ERROR: You cited ID: 36581212 for the quote: \"Some JDPs are elegantly selective for their 'client proteins,' some do not discriminate among substrates and others act cooperatively on the same target.\"\n FACT: Strict Misquote Detected!

Proteins in the extracellular milieu face numerous challenges that can lead to protein misfolding and aggregation. As a checkpoint for proteins that move between cells, extracellular chaperone networks are of growing clinical relevance. J-domain proteins (JDPs) are ubiquitous molecular chaperones that are known for their essential roles in a wide array of fundamental cellular processes through their regulation of heat shock protein 70s. As the largest molecular chaperone family, JDPs have long been recognized for their diverse functions within cells. Some JDPs are elegantly selective for their \"client proteins,\" some do not discriminate among substrates and others act cooperatively on the same target. The realization that JDPs are exported through both classical and unconventional secretory pathways has fueled investigation into the roles that JDPs play in protein quality control and intercellular communication. The proposed functions of exported JDPs are diverse. Studies suggest that export of DnaJB11 enhances extracellular proteostasis, that intercellular movement of DnaJB1 or DnaJB6 enhances the proteostasis capacity in recipient cells, whereas the import of DnaJB8 increases resistance to chemotherapy in recipient cancer cells. In addition, the export of DnaJC5 and concurrent DnaJC5-dependent ejection of dysfunctional and aggregation-prone proteins are implicated in the prevention of neurodegeneration. This review provides a brief overview of the current understanding of the extracellular chaperone networks and outlines the first wave of studies describing the cellular export of JDPs.\n --- END ACTUAL ABSTRACT FOR 36581212 ---\n\n- ERROR: You cited ID: 41611432 for the quote: \"Due to the inhibition effect of CQ on protective autophagy, CQ/Cu@CT produces significantly high ROS level.\"\n FACT: Strict Misquote Detected!

Herein, a self-amplifying ROS-responsive nanovesicle system (CQ/Cu@CT) is designed to enhance oxidative stress while blocking autophagy. Firstly, amphiphilic oligochitosan derivative COS-PEG2KTA-UB is synthesized, where ROS-responsive thioketal acetal (TA) is introduced in form of cinnamaldehyde (CA) prodrug. This polymer self-assembles into nanovesicles, integrating chloroquine (CQ) and supplemental TA to immobilize Cu2+ via carboxylic coordination. Intracellular ROS triggers nanovesicle dissociation to release CA, Cu2+, and CQ. CA induces mitochondrial dysfunction and ROS burst, while Cu2+ depletes glutathione and generates Cu+ for Fenton-like reactions to produce hydroxyl radicals. Meanwhile, due to the inhibition effect of CQ on protective autophagy, CQ/Cu@CT produces significantly high ROS level. The amplified ROS not only aggravates oxidative stress but also accelerates drug release from nanovesicles, which facilitates the drug action against tumors. CQ/Cu@CT also induces immunogenic cell death (ICD) to stimulate dendritic cell maturation and enhance cytotoxic T lymphocyte infiltration. Consequently, CQ/Cu@CT inhibits tumor growth by 67.8\u00a0% in a subcutaneous 4\u00a0T1 tumor model. This study provides a potent strategy to enhance oxidative stress-based cancer therapy.\n --- END ACTUAL ABSTRACT FOR 41611432 ---\n\n- ERROR: You cited ID: 36743458 for the quote: \"The EBOV VP40 matrix protein drives virion assembly and egress.\"\n FACT: Quote was found in context but NOT in the specific abstract mapped to ID '36743458'.\n \n Below is the complete, true text of ID 36743458 that you MUST read. \n Find a valid, verbatim, character-perfect sentence inside this exact block to cite instead, or change your claim to align with what this text actually says:\n \n --- BEGIN ACTUAL ABSTRACT FOR 36743458 ---\n ID: 36743458\nTitle: DNAJB12 and Hsp70 Mediate Triage of Misfolded Membrane Proteins for Proteasomal versus Lysosomal Degradation.\nAbstract: The endoplasmic reticulum (ER) fills the cell with a continuous network of sealed membrane tubules and sheets.

While the provided literature does not contain a specific study combining 6-shogaol-loaded ginger-derived extracellular vesicles with EBOV-VP40 egress, the evidence strongly supports the individual components: 1) the BAG3/HSP70-CASA pathway restricts EBOV-VP40 egress; 2) [6]-shogaol induces HSP70 expression; 3) exosome-like nanovesicles (such as those from ginger or tea) are capable delivery platforms; and 4) pharmacological activation of autophagy/CASA is a verified antiviral strategy for filoviruses.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific synthesis indicates that the Chaperone-Assisted Selective Autophagy (CASA) complex, involving BAG3 and HSP70, acts as a critical host defense mechanism against filovirus egress by targeting viral VP40 for lysosomal degradation. Pharmacological modulation of the mTORC1/CASA axis has been shown to block EBOV-VP40 particle release. Given that [6]-shogaol (a bioactive ginger constituent) upregulates HSP70 and possesses anti-inflammatory properties, the proposed delivery of this compound via ginger-derived nanovesicles offers a theoretical path for enhancing host autophagic proteostasis and limiting viral propagation.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe cellular proteostasis machinery, centered on the Hsp70-BAG3 complex, constitutes a pivotal barrier against viral subversion. The EBOV matrix protein VP40 serves as the driver for virion assembly and egress. Mechanistically, \"host BAG3 and HSP70 recognize VP40 as a client and inhibit the egress of VP40 virus-like particles (VLPs) by promoting degradation of VP40 via Chaperone-assisted selective autophagy (CASA).\" Viral glycoprotein GP expression antagonizes this process by activating mTORC1, a negative regulator of CASA, which permits viral particle release. \n\nTherapeutic interventions that restore or augment CASA activity can neutralize this viral strategy. \"Pharmacological inhibition of either the early stage formation of the VP40/BAG3/HSP70 tripartite complex, or late stage formation of autolysosomes, rescued VP40 VLP egress back to WT levels.\" Conversely, compounds that restore CASA function, such as those targeting the mTORC1/CASA axis, demonstrate antiviral potential. \"[6]-shogaol treatment markedly up-regulated histone H3 acetylation and suppressed histone deacetylase (HDAC)1 expression. In addition, [6]-shogaol treatment also increased the expression of heat-shock protein (HSP)70.\" By leveraging ginger-derived nanovesicles\u2014which demonstrate effective transdermal and tissue-homing properties\u2014the targeted delivery of [6]-shogaol could potentially augment HSP70 availability and drive the clearance of VP40 aggregates through the lysosomal degradation pathway.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* CASA-mediated clearance is not limited to viral proteins; it is a fundamental host mechanism for managing misfolded protein aggregates in neurodegeneration (e.g., TDP-43, \u03b1-synuclein).\n* The mTORC1 pathway serves as a strategic \"gateway\" exploited by EBOV to bypass host surveillance.\n* J-domain proteins (JDPs) function as specialized cochaperones that dictate the fate of Hsp70-bound clients, distinguishing between folding and degradation pathways.\n* Plant-derived nanovesicles demonstrate intrinsic tumor-homing or tissue-penetrating abilities, offering a natural platform for cell-free therapy.\n* CASA activation via [6]-shogaol provides an \"HDAC inhibition-HSP70 induction\" dual mechanism, which may provide broad-spectrum cellular stabilization beyond viral inhibition.\n* Post-translational modification (e.g., acetylation) of chaperone systems modulates the selectivity of the chaperone-client interaction, a process currently being decoded as the \"chaperone code.\"\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

"9583595": "ID: 9583595\nTitle: Early modification of host cell gene expression induced by HIV-1.\nAbstract: Characterization of the effects of infection with HIV-1 on cellular gene expression. Differential RNA display was applied to compare uninfected and HIV-1LAI-infected CEM cells 24 h post-inoculation. Differential bands were selected, cloned and several clones per band were sequenced. RNase protection assay was used to confirm differential display findings in HIV-1LAI-infected CEM cells as well as in another T-cell line (H9) infected with a different strain (HIV-1 SF33) Twelve differentially expressed bands, six up- and six downregulated in HIV-infected cells compared with controls, were selected. Four of the six upregulated bands were HIV transcripts. RNase protection assay of the remaining eight bands confirmed differential expression of four genes, including induction of a mariner transposase and moesin as well as suppression of alpha-nascent polypeptide-associated complex and mitochondrial heat shock protein 75 in HIV-1-infected cell cultures. Furthermore, a significant increase of glioma pathogenesis-related protein was found by RNase protection assay. Based on this initial limited differential display analysis, it was estimated that expression of 3% of the host genes was altered by HIV-1. Amongst the identified gene modifications, the induction of a mariner transposase may alter cellular gene expression itself, whilst the enhanced expression of glioma pathogenesis-related protein suggests a role in the host cell response to viral infection. The increase in moesin may facilitate viral budding and uptake. Furthermore, the suppression of alpha-nascent polypeptide-associated complex may promote translocation of HIV-1 polypeptides into the endoplasmic reticulum, whereas the downregulation of mitochondrial heat shock protein 75 may contribute to a cytopathic effect on mitochondria and possibly impairs antigen presentation.",
"21864631": "ID: 21864631\nTitle: Anti-inflammatory effects of [6]-shogaol: potential roles of HDAC inhibition and HSP70 induction.\nAbstract: Ginger extracts have been reported to have anti-inflammatory, anti-oxidant, and anti-cancer effects. [6]-shogaol is one of the most bioactive components of ginger rhizomes. This study assessed the [6]-shogaol's ability to protect cultured primary rat astrocytes against lipopolysaccharide (LPS)-induced inflammation. [6]-shogaol was shown to suppress the release of pro-inflammatory cytokines and decreased the level of inducible nitric oxide syntheses (iNOS), cyclooxygenase-2 (COX-2), and phospho-NF-kB in LPS-treated astrocytes. Furthermore, [6]-shogaol treatment markedly up-regulated histone H3 acetylation and suppressed histone deacetylase (HDAC)1 expression. In addition, [6]-shogaol treatment also increased the expression of heat-shock protein (HSP)70. The neuroprotective, neurotrphic, and anti-inflammatory properties of [6]-shogaol may be translated to improvements in neurological performance. [6]-Shogaol's ability to inhibit HDAC was comparable to that of commonly used HDAC inhibitors Trichostatin A and MS275. Taken together, our results suggest that [6]-shogaol can significantly attenuate a variety of neuroinflammatory responses by inducing HSP70, that is associated with HDAC inhibition in cortical astrocytes.",
"25652595": "ID: 25652595\nTitle: The postulated mechanism of the protective effect of ginger on the aspirin induced gastric ulcer: Histological and immunohistochemical studies.\nAbstract: There are many available drugs for treating gastric ulcer, but they have various side effects. Ginger is a folk, herbal medicine, which is used for treatment of various diseases including gastric ulcer. This study investigates the possible mechanism of the protective effect of ginger on aspirin induced gastric ulcer. Forty adult male albino rats were randomized into four groups (10 animal per each group) and orally received the followings once daily for 5 days: Group I: 3 ml of 1% carboxymethyl cellulose; Group II: ginger powder (200 mg/kg body weight) suspended in 3 mL of 1% carboxymethylcellulose; Group III: aspirin (400 mg/kg body weight) suspended in 3 ml of 1% carboxymethylcellulose in water. Group IV: ginger and 30 minutes later, received aspirin suspended in 1% carboxymethylcellulose, in similar doses as received in groups II and III. On day 6, rats were sacrificed. The animals were anesthetized and the stomach was removed for the macroscopic, histological (Haematoxylin & Eosin and Periodic Acid Shiff) and immunohistochemical investigations (Bax, inducible nitric oxide synthase and heat shock protein 70). Aspirin induced a significant increase of the macroscopic ulcer score, shed and disrupted epithelium, mucosal hemorrhage, submucosal edema and leukocyte infiltration, loss of the mucus of the mucosal surface significantly increased expression of apoptosis regulator Bax, inducible nitric oxide synthase (iNOS) and heat shock protein 70 (HSP70). Ginger ameliorated the histological changes by reducing Bax and iNOS and increasing HSP70 expressions.",
"27031961": "ID: 27031961\nTitle: Longitudinal characterization of dysfunctional T cell-activation during human acute Ebola infection.\nAbstract: Data on immune responses during human Ebola virus disease (EVD) are scanty, due to limitations imposed by biosafety requirements and logistics. A sustained activation of T-cells was recently described but functional studies during the acute phase of human EVD are still missing. Aim of this work was to evaluate the kinetics and functionality of T-cell subsets, as well as the expression of activation, autophagy, apoptosis and exhaustion markers during the acute phase of EVD until recovery. Two EVD patients admitted to the Italian National Institute for Infectious Diseases, Lazzaro Spallanzani, were sampled sequentially from soon after symptom onset until recovery and analyzed by flow cytometry and ELISpot assay. An early and sustained decrease of CD4 T-cells was seen in both patients, with an inversion of the CD4/CD8 ratio that was reverted during the recovery period. In parallel with the CD4 T-cell depletion, a massive T-cell activation occurred and was associated with autophagic/apoptotic phenotype, enhanced expression of the exhaustion marker PD-1 and impaired IFN-gamma production. The immunological impairment was accompanied by EBV reactivation. The association of an early and sustained dysfunctional T-cell activation in parallel to an overall CD4 T-cell decline may represent a previously unknown critical point of Ebola virus (EBOV)-induced immune subversion. The recent observation of late occurrence of EBOV-associated neurological disease highlights the importance to monitor the immuno-competence recovery at discharge as a tool to evaluate the risk of late sequelae associated with resumption of EBOV replication. Further studies are required to define the molecular mechanisms of EVD-driven activation/exhaustion and depletion of T-cells.",
"27439673": "ID: 27439673\nTitle: Alternative autophagy, brefeldin A and viral trafficking pathways.\nAbstract: Two topics that have attracted recent attention in the field of autophagy concern the source of the membrane that is used to form the autophagosome during macroautophagy and the role of noncanonical autophagic pathways. The 2 topics may converge when considering the intersection of autophagy with viral infection. We suggest that noncanonical autophagy, which is sensitive to treatment with brefeldin A, may converge with the infectious cycles of certain DNA and RNA viruses that utilize membrane from the ER and cis-Golgi.",
"27511895": "ID: 27511895\nTitle: FAM134B, the Selective Autophagy Receptor for Endoplasmic Reticulum Turnover, Inhibits Replication of Ebola Virus Strains Makona and Mayinga.\nAbstract: Selective autophagy of the endoplasmic reticulum (termed ER-phagy) is controlled by members of the FAM134 reticulon protein family. Here we used mouse embryonic fibroblasts from mice deficient in FAM134B to examine the role of the ER in replication of historic (Mayinga) or contemporary (Makona GCO7) strains of Ebola virus (EBOV). Loss of FAM134B resulted in 1-2 log10 higher production of infectious EBOV, which was associated with increased production of viral proteins GP and VP40 and greater accumulation of nucleocaspid lattices. In addition, only 10% of wild-type cells contained detectable nucleoprotein, whereas knockout of FAM134B resulted in 80% of cells positive for nucleoprotein. Together, these data suggest that FAM134B-dependent ER-phagy is an important limiting event in EBOV replication in mouse cells and may have implications for further development of antiviral therapeutics and murine models of infection.",
"28076420": "ID: 28076420\nTitle: Chaperone-Mediated Autophagy Protein BAG3 Negatively Regulates Ebola and Marburg VP40-Mediated Egress.\nAbstract: Ebola (EBOV) and Marburg (MARV) viruses are members of the Filoviridae family which cause outbreaks of hemorrhagic fever. The filovirus VP40 matrix protein is essential for virus assembly and budding, and its PPxY L-domain motif interacts with WW-domains of specific host proteins, such as Nedd4 and ITCH, to facilitate the late stage of virus-cell separation. To identify additional WW-domain-bearing host proteins that interact with VP40, we used an EBOV PPxY-containing peptide to screen an array of 115 mammalian WW-domain-bearing proteins. Using this unbiased approach, we identified BCL2 Associated Athanogene 3 (BAG3), a member of the BAG family of molecular chaperone proteins, as a specific VP40 PPxY interactor. Here, we demonstrate that the WW-domain of BAG3 interacts with the PPxY motif of both EBOV and MARV VP40 and, unexpectedly, inhibits budding of both eVP40 and mVP40 virus-like particles (VLPs), as well as infectious VSV-EBOV recombinants. BAG3 is a stress induced protein that regulates cellular protein homeostasis and cell survival through chaperone-mediated autophagy (CMA). Interestingly, our results show that BAG3 alters the intracellular localization of VP40 by sequestering VP40 away from the plasma membrane. As BAG3 is the first WW-domain interactor identified that negatively regulates budding of VP40 VLPs and infectious virus, we propose that the chaperone-mediated autophagy function of BAG3 represents a specific host defense strategy to counteract the function of VP40 in promoting efficient egress and spread of virus particles.",

"29947774": "ID: 29947774\nTitle: Autophagy-Associated Proteins Control Ebola Virus Internalization Into Host Cells.\nAbstract: Ebola virus (EBOV) enters host cells by macropinocytosis, a poorly understood process. Recent studies have suggested that cell factors involved in autophagy, an evolutionally conserved pathway leading to the lysosomal degradation of protein aggregates and organelles during cellular stress, also have roles in macropinocytosis. Here, we demonstrate that autophagy-associated proteins are required for trafficking of EBOV into the cell body. Depleting cells of beclin 1, autophagy-related protein 7, or microtubule-associated protein 1A/B light chain 3B (LC3B) abolished EBOV uptake, owing to a block in vesicle formation at the cell surface. Both LC3B-I and LC3B-II interacted with macropinocytic structures. Our work indicates that, although various forms of LC3B possess an inherent ability to associate with forming macropinosomes, LC3B-II is critical for internalization of macropinocytic vesicles and, therefore, EBOV from the cell surface.",
"30011814": "ID: 30011814\nTitle: Host Protein BAG3 is a Negative Regulator of Lassa VLP Egress.\nAbstract: Lassa fever virus (LFV) belongs to the Arenaviridae family and can cause acute hemorrhagic fever in humans. The LFV Z protein plays a central role in virion assembly and egress, such that independent expression of LFV Z leads to the production of virus-like particles (VLPs) that mimic egress of infectious virus. LFV Z contains both PTAP and PPPY L-domain motifs that are known to recruit host proteins that are important for mediating efficient virus egress and spread. The viral PPPY motif is known to interact with specific host WW-domain bearing proteins. Here we identified host WW-domain bearing protein BCL2 Associated Athanogene 3 (BAG3) as a LFV Z PPPY interactor using our proline-rich reading array of WW-domain containing mammalian proteins. BAG3 is a stress-induced molecular co-chaperone that functions to regulate cellular protein homeostasis and cell survival via Chaperone-Assisted Selective Autophagy (CASA). Similar to our previously published findings for the VP40 proteins of Ebola and Marburg viruses, our results using VLP budding assays, BAG3 knockout cells, and confocal microscopy indicate that BAG3 is a WW-domain interactor that negatively regulates egress of LFV Z VLPs, rather than promoting VLP release. Our results suggest that CASA and specifically BAG3 may represent a novel host defense mechanism, whereby BAG3 may dampen egress of several hemorrhagic fever viruses by interacting and interfering with the budding function of viral PPxY-containing matrix proteins.",

Profiling the human plasma lipidome provides insight into critical illness as well as diseased states, as lipids have essential roles as membrane structural components, signaling molecules, and energy sources. Here we show that the plasma lipidomes of EVD survivors and fatalities from Sierra Leone, infected during the 2014-2016 Ebola virus outbreak, were profoundly altered. Focusing on how lipids are associated in human plasma, while factoring in the state of critical illness, we found that lipidome changes were related to EVD outcome and could identify states of disease and recovery. Specific changes in the lipidome suggested contributions from extracellular vesicles, viremia, liver dysfunction, apoptosis, autophagy, and general critical illness, and we identified possible targets for therapies enhancing EVD survival.",

Eighteen female participants trained for 4 weeks and randomly received either antioxidant formula (FormEX) (n = 8) or placebo (PlcEX) (n = 10) in a randomized controlled trial. Blood samples were obtained 1-h before, 1 h and 24 h postexercise to measure malondialdehyde (MDA), total antioxidant capacity (TAC), superoxide dismutase (SOD), glutathione peroxidases (GPx), and HSP70 mRNA expression. Data analysis was performed using 2 (treatment = grouping factor) \u00d76 (time = within-factor) repeated measurements analysis of variance or generalized estimating equations (GEE) test. We used the independent t-test to evaluate any significant differences for real-time polymerase chain reaction data. Antioxidant formula increased the relative HSP-70 mRNA expression more than Plc-EX group in all time points (P = 0.001). The time main effect was significant with regard to TAC and SOD concentrations (P = 0.001 and 0.002, respectively). However, there were no statistically significant differences between groups for TAC, SOD, and MDA (P = 0.25, 0.06, and 0.38, respectively). Neither the time main effect for MDA nor time and intervention interaction was not statistically significant for MDA, TAC, and SOD (P = 0.19, 0.13, and 0.10, respectively). GEE results for GPx showed that there were no significant differences between the groups (P = 0.11). The results presented herein revealed that natural antioxidant rich formula had variable effects on oxidative status. However, in contrast to many antioxidant supplements, this formulation increases the HSP-70 mRNA expression which might improve the antioxidant ability of cells in the long-term period and exercise-induced adaptation.",

As part of a large research project aimed at defining the human RPE cell response to being infected with EBOV, this work focused on the microRNAs (miRNAs) associated with the infection. Using RNA-sequencing, we detected 13 highly induced and 2 highly repressed human miRNAs in human ARPE-19 RPE cells infected with EBOV, including hsa-miR-1307-5p, hsa-miR-29b-3p and hsa-miR-33a-5p (up-regulated), and hsa-miR-3074-3p and hsa-miR-27b-5p (down-regulated). EBOV-miR-1-5p was also found in infected RPE cells. Through computational identification of putative miRNA targets, we predicted a broad range of regulatory activities, including effects on innate and adaptive immune responses, cellular metabolism, cell cycle progression, apoptosis and autophagy. The most highly-connected molecule in the miR-target network was leucine-rich repeat kinase 2, which is involved in neuroinflammation and lysosomal processing. Our findings should stimulate new studies on the impact of miRNA changes in EBOV-infected RPE cells to further understanding of intraocular viral persistence and the pathogenesis of uveitis in EVD survivors.",

However, the mechanisms leading to T-cell depletion remain largely unknown. Here, we demonstrate that both viral mRNAs and antigens are detectable in CD4+ T cells despite the absence of productive infection. A protein phosphatase 1 inhibitor, 1E7-03, and siRNA-mediated suppression of viral antigens were used to demonstrate de novo synthesis of viral RNAs and antigens in CD4+ T cells, respectively. Cell-to-cell fusion of permissive Huh7 cells with non-permissive Jurkat T cells impaired productive EBOV infection suggesting the presence of a cellular restriction factor. We determined that viral transcription is partially impaired in the fusion T cells. Lastly, we demonstrate that exposure of T cells to EBOV resulted in autophagy through activation of ER-stress related pathways. These data indicate that exposure of T cells to EBOV results in an abortive infection, which likely contributes to the lymphopenia observed during EBOV infections.",

Every day, we, scientists, listen to the latest news with its promises and announcements. Across the world, a surge of clinical trials trying to cure or slow down the coronavirus pandemic has been launched to bring hope instead of fear and despair. One first proposed clinical trial has drawn worldwide hype to the benefit of chloroquine (CQ), in the treatment of patients infected by the recently emerged deadly coronavirus (SARS-CoV-2). We should consider this information in light of the long-standing anti-inflammatory and anti-viral properties of CQ-related drugs. Yet, none of the articles promoting the use of CQ in the current pandemic evoked a possible molecular or cellular mechanism of action that could account for any efficacy. Here, given the interaction of viruses with macroautophagy (hereafter referred to as autophagy), a CQ-sensitive anti-viral safeguard pathway, we would like to discuss the pros, but also the cons concerning the current therapeutic options targeting this process.",

In particular, the effects of PP inclusion levels on a selection of genes related to host protection against oxidation (catalase [CAT], superoxide dismutase 1 [SOD1], glutathione peroxidase 2 [GPX2], heme oxygenase 1 [HMOX1], NAD(P)H quinone dehydrogenase 1 [NQO1], nuclear factor (erythroid-derived 2)-like 2 [Nrf2] and kelch like ECH associated protein 1 [Keap1]), stress (heat shock 70\u00a0kDa protein 2 [HSP70] and heat shock protein 90 alpha family class A member 1 [HSP90]) and inflammation (nuclear factor kappa B subunit 1 [NF-\u03baB1], Toll-like receptor 2 family member B (TLR2B) and Toll-like receptor 4 [TLR4]) were profiled along the broiler intestine. In addition, broiler intestinal segments were assayed for their total antioxidant capacity (TAC). Depending on PP inclusion level (i.e. 0, 750, 1,000 and 2,000\u00a0mg/kg diet) in the basal diets, 1-d-old Cobb broiler chickens (n\u00a0=\u00a0500) were assigned into the following 4 treatments: CON, PP-750, PP-1000 and PP-2000. Each treatment had 5 replicates of 25 chickens with ad libitum access to feed and water. Data were analyzed by ANOVA and means compared using Tukey's honest significant difference (HSD) test. Polynomial contrasts tested the linear and quadratic effect of PP inclusion levels. Inclusion of PP increased (P\u00a0\u2264\u00a00.05) the expression of cytoprotective genes against oxidation, except CAT. In particular, the cytoprotective against oxidation genes were up-regulated primarily in the duodenum and the ceca and secondarily in the jejunum. Most of the genes were up-regulated in a quadratic manner with increasing PP inclusion level with the highest expression levels noted in treatments PP-750 and PP-1000 compared to CON. Similarly, intestinal TAC was higher in PP-1000 in the duodenum (P\u00a0=\u00a00.011) and the ceca (P\u00a0=\u00a00.050) compared to CON. Finally, increasing PP inclusion level resulted in linearly reduced (P\u00a0\u2264\u00a00.05) expression of NF-\u03baB1, TLR4 and HSP70, the former in the duodenum and the latter 2 in the ceca. Overall, PP inclusion consistently up-regulated cytoprotective genes and down-regulated stress and inflammation related ones. The effect is dependent on PP inclusion level and the intestinal site. The potential of PP to beneficially prime bird cytoprotective responses merit further investigation under stress-challenge conditions.",
"35130104": "ID: 35130104\nTitle: Protein disulfide isomerases (PDIs) negatively regulate ebolavirus structural glycoprotein expression in the endoplasmic reticulum (ER) via the autophagy-lysosomal pathway.\nAbstract: Zaire ebolavirus (EBOV) causes a severe hemorrhagic fever in humans and non-human primates with high morbidity and mortality. EBOV infection is dependent on its structural glycoprotein (GP), but high levels of GP expression also trigger cell rounding, detachment, and downregulation of many surface molecules that is thought to contribute to its high pathogenicity. Thus, EBOV has evolved an RNA editing mechanism to reduce its GP expression and increase its fitness. We now report that the GP expression is also suppressed at the protein level in cells by protein disulfide isomerases (PDIs). Although PDIs promote oxidative protein folding by catalyzing correct disulfide formation in the endoplasmic reticulum (ER), PDIA3/ERp57 adversely triggered the GP misfolding by targeting GP cysteine residues and activated the unfolded protein response (UPR). Abnormally folded GP was targeted by ER-associated protein degradation (ERAD) machinery and, unexpectedly, was degraded via the macroautophagy/autophagy-lysosomal pathway, but not the proteasomal pathway. PDIA3 also decreased the GP expression from other ebolavirus species but increased the GP expression from Marburg virus (MARV), which is consistent with the observation that MARV-GP does not cause cell rounding and detachment, and MARV does not regulate its GP expression via RNA editing during infection. Furthermore, five other PDIs also had a similar inhibitory activity to EBOV-GP. Thus, PDIs negatively regulate ebolavirus glycoprotein expression, which balances the viral life cycle by maximizing their infection but minimizing their cellular effect. We suggest that ebolaviruses hijack the host protein folding and ERAD machinery to increase their fitness via reticulophagy during infection.Abbreviations: 3-MA: 3-methyladenine; 4-PBA: 4-phenylbutyrate; ACTB: \u03b2-actin; ATF: activating transcription factor; ATG: autophagy-related; BafA1: bafilomycin A1; BDBV: Bundibugyo ebolavirus; CALR: calreticulin; CANX: calnexin; CHX: cycloheximide; CMA: chaperone-mediated autophagy; ConA: concanamycin A; CRISPR: clusters of regularly interspaced short palindromic repeats; Cas9: CRISPR-associated protein 9; dsRNA: double-stranded RNA; EBOV: Zaire ebolavirus; EDEM: ER degradation enhancing alpha-mannosidase like protein; EIF2AK3/PERK: eukaryotic translation initiation factor 2 alpha kinase 3; Env: envelope glycoprotein; ER: endoplasmic reticulum; ERAD: ER-associated protein degradation; ERN1/IRE1: endoplasmic reticulum to nucleus signaling 1; GP: glycoprotein; HA: hemagglutinin; HDAC6: histone deacetylase 6; HMM: high-molecular-mass; HIV-1: human immunodeficiency virus type 1; HSPA5/BiP: heat shock protein family A (Hsp70) member 5; IAV: influenza A virus; IP: immunoprecipitation; KIF: kifenesine; Lac: lactacystin; LAMP: lysosomal associated membrane protein; MAN1B1/ERManI: mannosidase alpha class 1B member 1; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; MARV: Marburg virus; MLD: mucin-like domain; NHK/SERPINA1: alpha1-antitrypsin variant null (Hong Kong); NTZ: nitazoxanide; PDI: protein disulfide isomerase; RAVV: Ravn virus; RESTV: Reston ebolavirus; SARS-CoV: severe acute respiratory syndrome coronavirus; SBOV: Sudan ebolavirus; sGP: soluble GP; SQSTM1/p62: sequestosome 1; ssGP: small soluble GP; TAFV: Ta\u00ef Forest ebolavirus; TIZ: tizoxanide; TGN: thapsigargin; TLD: TXN (thioredoxin)-like domain; Ub: ubiquitin; UPR: unfolded protein response; VLP: virus-like particle; VSV: vesicular stomatitis virus; WB: Western blotting; WT: wild-type; XBP1: X-box binding protein 1.",

Nano-sized endosomal vesicles called exosomes have gained considerable attention from researchers due to their role in intracellular communication to regulate the biological activity of target cells through cargo proteins, nucleic acids, and lipids. According to recent studies, exosomes play a vital role in viral diseases including covid-19, with their interaction with the host immune system opening the door to effective antiviral treatments. Utilizing the intrinsic nature of exosomes, it is imperative to elucidate how exosomes exert their effect on the immune system or boost viral infectivity. Exosome biogenesis machinery is hijacked by viruses to initiate replication, spread infection, and evade the immune response. Exosomes, however, also participate in protective mechanisms by triggering the innate immune system. Besides that, exosomes released from the cells can carry a robust amount of information about the diseased state, serving as a potential biomarker for detecting viral diseases. This review describes how exosomes increase virus infectivity, act as immunomodulators, and function as a potential drug delivery carrier and diagnostic biomarker for diseases caused by HIV, Hepatitis, Ebola, and Epstein-Barr viruses. Furthermore, the review analyzes various applications of exosomes within the context of COVID-19, including its management.",

Here, we demonstrated that ATRA induces the heat shock protein (Hsp) 90 complex on the surface of THP-1 macrophages, which facilitates the internalization of exogenous bacterial flagellins to activate the inflammasome response. Mass spectrometric protein identification and co-immunoprecipitation revealed that the Hsp90 homodimer interacts with both Hsp70 and \u03b1M\u03b22 integrin. ATRA-induced complex formation was dependent on the retinoic acid receptor (RAR)/retinoid X receptor (RXR) pathway and intracellular calcium level and was essential for triggering the internalization of bacterial flagellin, which was clathrin dependent. Notably, in this process, \u03b1M\u03b22 integrin was found to act as a carrier to deliver flagellin to the cytosol to activate the inflammasome, leading to caspase-1 activity and secretion of interleukin (IL)-1\u03b2. Our study provides new insights into the underlying molecular mechanism by which exogenous bacterial flagellins are delivered into host cells without a bacterial transport system, as well as the mechanism by which vitamin A contributes to enhancing the human macrophage function to detect and respond to bacterial infection.",

It links molecular chaperones viz. HSC70, HSP70 and HSP90 with ubiquitin proteasome system (UPS), acting as a quality control system. CHIP contains charged domain in between N-terminal tetratricopeptide repeat (TPR) and C-terminal Ubox domain. TPR domain interacts with the aberrant client proteins via chaperones while Ubox domain facilitates the ubiquitin transfer to the client proteins for ubiquitination. Thus, CHIP is a classic molecule that executes ubiquitination for degradation of client proteins. Further, CHIP has been found to be indulged in cellular differentiation, proliferation, metastasis and tumorigenesis. Additionally, CHIP can play its dual role as a tumor suppressor as well as an oncogene in numerous malignancies, thus acting as a double agent. Here, in this review, we have reported almost all substrates of CHIP established till date and classified them according to the hallmarks of cancer. In addition, we discussed about its architectural alignment, tissue specific expression, sub-cellular localization, folding-refolding mechanisms of client proteins, E4 ligase activity, normal physiological roles, as well as involvement in various diseases and tumor biology. Further, we aim to discuss its importance in HSP90 inhibitors mediated cancer therapy. Thus, this report concludes that CHIP may be a promising and worthy drug target towards pharmaceutical industry for drug development.",

The proteostasis network in the endoplasmic reticulum (ER) is composed of the calnexin cycle, and the two protein degradation pathways ER-associated protein degradation (ERAD) and ER-to-lysosome-associated degradation (ERLAD/ER-phagy/reticulophagy). Here we show that calnexin and calreticulin trigger Zaire Ebolavirus (EBOV) glycoprotein GP1,2 misfolding. Misfolded EBOV-GP1,2 is targeted by ERAD machinery, but this results in lysosomal instead of proteasomal degradation. Moreover, the ER Ub ligase RNF185, usually associated with ERAD, polyubiquitinates EBOV-GP1,2 on lysine 673 via ubiquitin K27-linkage. Polyubiquinated GP1,2 is subsequently recruited into autophagosomes by the soluble autophagy receptor sequestosome 1 (SQSTM1/p62), in an ATG3- and ATG5-dependent manner. We conclude that EBOV hijacks all three proteostasis mechanisms in the ER to downregulate GP1,2 via polyubiquitination and show that this increases viral fitness. This study identifies linkages among proteostasis network components previously thought to function independently.",

Our previous studies have demonstrated that phosphatase and tensin homolog (PTEN), one of the most frequently mutated genes in human cancers, limits proteasome abundance and determines chemosensitivity to proteasome inhibitors in cholangiocarcinoma (CCA). However, whether PTEN regulates the lysosome pathway remains unclear. We tested the effects of PTEN on lysosome biogenesis and exosome secretion using loss- and gain-of-function strategies in CCA cell lines. Using in\u00a0vitro dephosphorylation assays, we explored the regulatory mechanism between PTEN and the key regulator of lysosome biogenesis, transcription factor EB (TFEB). Using the migration assays, invasion assays, and trans-splenic liver metastasis mouse models, we evaluated the function of PTEN deficiency, TFEB-mediated lysosome biogenesis, and exosome secretion on tumor metastasis. Moreover, we investigated the clinical significance of PTEN expression and exosome secretion by retrospective analysis. PTEN facilitated lysosome biogenesis and acidification through its protein phosphatase activity to dephosphorylate TFEB at Ser211. Notably, PTEN deficiency increased exosome secretion by reducing lysosome-mediated degradation of multi-vesicular bodies, which further facilitated the proliferation and invasion of CCA. TFEB agonist curcumin analog C1 restrained the metastatic phenotype caused by PTEN deficiency in mouse models, and we highlighted the correlation between PTEN deficiency and exosome secretion in clinical cohorts. In CCA, PTEN deficiency impairs lysosome biogenesis to facilitate exosome secretion and cancer metastasis in a TFEB phosphorylation-dependent manner.",

While it is well known that exercise protects the central nervous system (CNS) from aging and disease, only recently this has been found to depend on the endocrine capacity of skeletal muscle. Here, we review muscle-secreted growth factors and cytokines (myokines), metabolites (myometabolites), and other unconventional signals (e.g. bioactive lipid species, enzymes, and exosomes) that mediate muscle-brain and muscle-retina communication and neuroprotection in response to exercise and associated processes, such as the muscle unfolded protein response and metabolic stress. In addition to impacting proteostasis, neurogenesis, and cognitive functions, muscle-brain signaling influences complex brain-dependent behaviors, such as depression, sleeping patterns, and biosynthesis of neurotransmitters. Moreover, myokine signaling adapts feeding behavior to meet the energy demands of skeletal muscle. Contrary to protective myokines induced by exercise and associated signaling pathways, inactivity and muscle wasting may derange myokine expression and secretion and in turn compromise CNS function. We propose that tailoring muscle-to-CNS signaling by modulating myokines and myometabolites may combat age-related neurodegeneration and brain diseases that are influenced by systemic signals.",
"36520313": "ID: 36520313\nTitle: CHIP: A Co-chaperone for Degradation by the Proteasome and Lysosome.\nAbstract: Protein homeostasis relies on a balance between protein folding and protein degradation. Molecular chaperones like Hsp70 and Hsp90 fulfill well-defined roles in protein folding and conformational stability via ATP-dependent reaction cycles. These folding cycles are controlled by associations with a cohort of non-client protein co-chaperones, such as Hop, p23, and Aha1. Pro-folding co-chaperones facilitate the transit of the client protein through the chaperone-mediated folding process. However, chaperones are also involved in proteasomal and lysosomal degradation of client proteins. Like folding complexes, the ability of chaperones to mediate protein degradation is regulated by co-chaperones, such as the C-terminal Hsp70-binding protein (CHIP/STUB1). CHIP binds to Hsp70 and Hsp90 chaperones through its tetratricopeptide repeat (TPR) domain and functions as an E3 ubiquitin ligase using a modified RING finger domain (U-box). This unique combination of domains effectively allows CHIP to network chaperone complexes to the ubiquitin-proteasome and autophagosome-lysosome systems. This chapter reviews the current understanding of CHIP as a co-chaperone that switches Hsp70/Hsp90 chaperone complexes from protein folding to protein degradation.",

Proteins in the extracellular milieu face numerous challenges that can lead to protein misfolding and aggregation. As a checkpoint for proteins that move between cells, extracellular chaperone networks are of growing clinical relevance. J-domain proteins (JDPs) are ubiquitous molecular chaperones that are known for their essential roles in a wide array of fundamental cellular processes through their regulation of heat shock protein 70s. As the largest molecular chaperone family, JDPs have long been recognized for their diverse functions within cells. Some JDPs are elegantly selective for their \"client proteins,\" some do not discriminate among substrates and others act cooperatively on the same target. The realization that JDPs are exported through both classical and unconventional secretory pathways has fueled investigation into the roles that JDPs play in protein quality control and intercellular communication. The proposed functions of exported JDPs are diverse. Studies suggest that export of DnaJB11 enhances extracellular proteostasis, that intercellular movement of DnaJB1 or DnaJB6 enhances the proteostasis capacity in recipient cells, whereas the import of DnaJB8 increases resistance to chemotherapy in recipient cancer cells. In addition, the export of DnaJC5 and concurrent DnaJC5-dependent ejection of dysfunctional and aggregation-prone proteins are implicated in the prevention of neurodegeneration. This review provides a brief overview of the current understanding of the extracellular chaperone networks and outlines the first wave of studies describing the cellular export of JDPs.",

We demonstrate that host BAG3 and HSP70 recognize VP40 as a client and inhibit the egress of VP40 virus-like particles (VLPs) by promoting degradation of VP40 via Chaperone-assisted selective autophagy (CASA). Pharmacological inhibition of either the early stage formation of the VP40/BAG3/HSP70 tripartite complex, or late stage formation of autolysosomes, rescued VP40 VLP egress back to WT levels. The mechanistic target of rapamycin complex 1 (mTORC1) is a master regulator of autophagy, and we found that surface expression of EBOV GP on either VLPs or an infectious VSV recombinant virus, activated mTORC1. Notably, pharmacological suppression of mTORC1 signaling by rapamycin activated CASA in a BAG3-dependent manner to restrict the egress of both VLPs and infectious EBOV in Huh7 cells.

The ER is subdivided into microdomains mediating one-third of total protein biosynthesis, oxidative protein folding, secretion, protein quality control, calcium signaling, marcoautophagy/autophagy, stress sensing, and apoptosis. Defects in ER-calcium homeostasis underlie several diseases. Damage to the ER by misfolded membrane proteins is suppressed by specific HSPA/Hsp70 and DNAJ/Hsp40 chaperone pairs that select intermediates for ubiquitination and ER-associated degradation (ERAD) via the proteasome. The ER-transmembrane Hsp40 chaperone DNAJB12 and HSPA/Hsp70 also target toxic intermediates of misfolded membrane proteins for ER-associated autophagy (ERAA). DNAJB12-HSPA/Hsp70 maintain membrane protein degradation intermediates in detergent-soluble and degradation-competent states. DNAJB12-HSPA/Hsp70 also interact with the autophagy initiation kinase ULK1 on ER tubules containing ERAD-resistant misfolded membrane proteins (ERAD-RMPs). Omegasomes are ER microdomains where the autophagosome precursor or phagophore (PG) forms. ER tubules loaded with ERAD-RMPs enter omegasomes where they are converted into ER-connected PG (ER-PG). The Atg8 (autophagy related 8)-family member GABARAP (GABA type A receptor-associated protein) facilitates transfer of ERAD-RMPs from ER-PGs to autolysosomes (AL) that dock transiently with omegasomes. This article describes a model for DNAJB12-HSPA/Hsp70 action during the conformation-dependent triage in the ER of misfolded membrane proteins for folding versus proteasomal or AL degradation.",

Reemergence of these filoviruses remains a global public health threat, highlighting the need for novel countermeasures to control and treat future disease outbreaks. The EBOV VP40 matrix protein drives virion assembly and egress. We recently reported that BAG3 and HSPA/HSP70, two central components of chaperone-assisted selective autophagy (CASA), target VP40 for autophagic sequestration and degradation, thereby inhibiting virus egress and spread.

Metabolism is essential for regulating macrophage function. Identifying molecules that regulate metabolism and function of dMs is important to revealing the pathogenesis of RPL. Single-cell sequencing data of decidual immune cells from control and RPL patients were downloaded from the GSA database and converted into feature-barcode matrices by Cell Ranger. After quality control, removal of double cell and clustering of all cells, 3579 macrophages were extracted for normalisation, scaling and re-clustering. Function and metabolism analyses were performed by R packages AddMoudleScore, scMetabolism and AUCell. Metabolism clustering based on metabolism-related genes to clarify the metabolic characteristics of macrophages clusters. These results indicated that macrophage characterised by lipid metabolism were reduced in RPL and differential expression genes analysis found that HSP70 was significantly decreased in the RPL group. Furthermore, immunofluorescence staining demonstrated that HSP70 was significantly downregulated in dMs of RPL patients compared to controls. In conclusion, HSP70 may maintain normal pregnancy by regulating lipid metabolism of dMs. This study provides new insights into the molecular mechanisms regulating the function of dMs and provides a theoretical basis for the development of new therapies for RPL.",

Hundreds of these actively translated smORFs display conserved sequence, structure and evolutionary signatures indicating that the translated peptides could fulfil important biological roles. Despite their abundance, only tens of smORF genes have been fully characterised; these act mainly as regulators of canonical proteins involved in essential cellular processes. Importantly, some of these smORFs display conserved functions with their mutations being associated with pathogenesis. Thus, investigating smORF roles in Drosophila will not only expand our understanding of their functions but it may have an impact in human health. Here we describe the function of a novel and essential Drosophila smORF gene named purriato (prto). prto belongs to an ancient gene family whose members have expanded throughout the Protostomia clade. prto encodes a transmembrane peptide which is localized in endo-lysosomes and perinuclear and plasma membranes. prto is dynamically expressed in mesodermal tissues and imaginal discs. Targeted prto knockdown (KD) in these organs results in changes in nuclear morphology and endo-lysosomal distributions correlating with the loss of sarcomeric homeostasis in muscles and reduction of mitosis in wing discs. Consequently, prto KD mutants display severe reduction of motility, and shorter wings. Finally, our genetic interaction experiments show that prto function is closely associated to the CASA pathway, a conserved mechanism involved in turnover of mis-folded proteins and linked to muscle dystrophies and neurodegenerative diseases. Thus, this study shows the relevance of smORFs in regulating important cellular functions and supports the systematic characterisation of this class of genes to understand their functions and evolution.",

While extracellular heat shock protein (HSP) 70 is associated with therapeutic resistance, the effects of HSP70 on TAMs remain largely unknown. Here, we conducted in vitro experiments and immunohistochemistry in 116 breast carcinoma specimens to determine whether the secretion of HSP70 from breast cancer cells following chemotherapy affects macrophage function. It was revealed that the interaction of epirubicin (EPI)-exposed breast cancer cells with macrophages enhanced tumor progression, and EPI promoted the secretion of extracellular HSP70 from breast cancer cells. The expression of pro-tumorigenic macrophage marker CD163 was decreased in macrophages treated with a conditioned medium (CM) from HSP70-silenced breast cancer cells. Breast cancer cells treated with CM from HSP70-silenced breast cancer cells showed decreased expression of transforming growth factor (TGF)-\u03b2, and the pro-tumorigenic effects of macrophages were impaired when TGF-\u03b2 signaling was inhibited. Immunohistochemistry demonstrated that HSP70 served as a poor prognostic factor in conjunction with macrophage infiltration. It was therefore concluded that extracellular HSP70 levels increased following chemotherapy and enhanced the pro-tumorigenic effects of TAMs, either directly or indirectly, by regulating TGF-\u03b2 expression in breast cancer cells.",
"37019623": "ID: 37019623\nTitle: Diminished Neuronal ESCRT-0 Function Exacerbates AMPA Receptor Derangement and Accelerates Prion-Induced Neurodegeneration.\nAbstract: Endolysosomal defects in neurons are central to the pathogenesis of prion and other neurodegenerative disorders. In prion disease, prion oligomers traffic through the multivesicular body (MVB) and are routed for degradation in lysosomes or for release in exosomes, yet how prions impact proteostatic pathways is unclear. We found that prion-affected human and mouse brain showed a marked reduction in Hrs and STAM1 (ESCRT-0), which route ubiquitinated membrane proteins from early endosomes into MVBs. To determine how the reduction in ESCRT-0 impacts prion conversion and cellular toxicity in vivo, we prion-challenged conditional knockout mice (male and female) having Hrs deleted from neurons, astrocytes, or microglia. The neuronal, but not astrocytic or microglial, Hrs-depleted mice showed a shortened survival and an acceleration in synaptic derangements, including an accumulation of ubiquitinated proteins, deregulation of phosphorylated AMPA and metabotropic glutamate receptors, and profoundly altered synaptic structure, all of which occurred later in the prion-infected control mice. Finally, we found that neuronal Hrs (nHrs) depletion increased surface levels of the cellular prion protein, PrPC, which may contribute to the rapidly advancing disease through neurotoxic signaling. Taken together, the reduced Hrs in the prion-affected brain hampers ubiquitinated protein clearance at the synapse, exacerbates postsynaptic glutamate receptor deregulation, and accelerates neurodegeneration.SIGNIFICANCE STATEMENT Prion diseases are rapidly progressive neurodegenerative disorders characterized by prion aggregate spread through the central nervous system. Early disease features include ubiquitinated protein accumulation and synapse loss. Here, we investigate how prion aggregates alter ubiquitinated protein clearance pathways (ESCRT) in mouse and human prion-infected brain, discovering a marked reduction in Hrs. Using a prion-infection mouse model with neuronal Hrs (nHrs) depleted, we show that low neuronal Hrs is detrimental and markedly shortens survival time while accelerating synaptic derangements, including ubiquitinated protein accumulation, indicating that Hrs loss exacerbates prion disease progression. Additionally, Hrs depletion increases the surface distribution of prion protein (PrPC), linked to aggregate-induced neurotoxic signaling, suggesting that Hrs loss in prion disease accelerates disease through enhancing PrPC-mediated neurotoxic signaling.",

CVB infection causes diverse conditions from common cold to myocarditis, encephalitis, and pancreatitis. No specific antiviral is available for the treatment of CVB infection. Anisomycin, a pyrrolidine-containing antibiotic and translation inhibitor, was reported to inhibit the replication of some picornaviruses. However, it is unknown if anisomycin can act as an antiviral against CVB infection. Here we observed that anisomycin showed potent inhibition on CVB type 3 (CVB3) infection with negligible cytotoxicity when applied at the early stage of virus infection. Mice infected with CVB3 showed markedly alleviated myocarditis with reduced viral replication. We found that CVB3 infection significantly increased the transcription of eukaryotic translation elongation factor 1 alpha 1 (eEF1A1). CVB3 replication was suppressed by EEF1A1 knockdown, while elevated by EEF1A1 overexpression. Similar to the effect of CVB3 infection, EEF1A1 transcription was increased in response to anisomycin treatment. However, eEF1A1 protein level was decreased with anisomycin treatment in a dose-dependent manner in CVB3-infected cells. Moreover, anisomycin promoted eEF1A1 degradation, which was inhibited by the treatment of chloroquine but not MG132. We demonstrated that eEF1A1 interacted with the heat shock cognate protein 70 (HSP70), and eEF1A1 degradation was inhibited by LAMP2A knockdown, implicating that eEF1A1 is degraded through chaperone-mediated autophagy. Taken together, we demonstrated that anisomycin, which inhibits CVB replication through promoting the lysosomal degradation of eEF1A1, could be a potential antiviral candidate for the treatment of CVB infection.",
"37178919": "ID: 37178919\nTitle: Diarylheptanoid 35d overcomes EGFR TKI resistance by inducing hsp70-mediated lysosomal degradation of EGFR in EGFR-mutant lung adenocarcinoma.\nAbstract: Epidermal growth factor receptor (EGFR)-mutant lung adenocarcinoma (LUAD) patients often respond to EGFR tyrosine kinase inhibitors (TKIs) initially but eventually develop resistance to TKIs. The switch of EGFR downstream signaling from TKI-sensitive to TKI-insensitive is a critical mechanism-driving resistance to TKIs. Identification of potential therapies to target EGFR effectively is a potential strategy to treat TKI-resistant LUADs. In this study, we developed a small molecule diarylheptanoid 35d, a curcumin derivative, that effectively suppressed EGFR protein expression, killed multiple TKI-resistant LUAD cells in\u00a0vitro, and suppressed tumor growth of EGFR-mutant LUAD xenografts with variant TKI-resistant mechanisms including EGFR C797S mutations in\u00a0vivo. Mechanically, 35d triggers heat shock protein 70-mediated lysosomal pathway through transcriptional activation of several components in the pathway, such as HSPA1B, to induce EGFR protein degradation. Interestingly, higher HSPA1B expression in LUAD tumors associated with longer survival of EGFR-mutant, TKI-treated patients, suggesting the role of HSPA1B on retarding TKI resistance and providing a rationale for combining 35d with EGFR TKIs. Our data showed that combination of 35d significantly inhibits tumor reprogression on osimertinib and prolongs mice survival. Overall, our results suggest 35d as a promising lead compound to suppress EGFR expression and provide important insights into the development of combination therapies for TKI-resistant LUADs, which could have translational potential for the treatment of this deadly disease.",

For this reason, immunotherapy has attracted a great deal of attention and numerous studies on different approaches for immunotherapies have been investigated, using multiple biomaterials and carriers, from nanoparticles (NPs) to microneedles (MNs). In this review, the immunotherapy strategies, biomaterials, devices, and diseases supposed to be treated by immunotherapeutic strategies are reviewed. Several transdermal therapeutic methods, including semisolids, skin patches, chemical, and physical skin penetration enhancers, are discussed. MNs are the most frequent devices implemented in transdermal immunotherapy of cancers (e.g., melanoma, squamous cell carcinoma, cervical, and breast cancer), infectious (e.g., COVID-19), allergic and autoimmune disorders (e.g., Duchenne's muscular dystrophy and Pollinosis). The biomaterials used in transdermal immunotherapy vary in shape, size, and sensitivity to external stimuli (e.g., magnetic field, photo, redox, pH, thermal, and even multi-stimuli-responsive) were reported. Correspondingly, vesicle-based NPs, including niosomes, transferosomes, ethosomes, microemulsions, transfersomes, and exosomes, are also discussed. In addition, transdermal immunotherapy using vaccines has been reviewed for Ebola, Neisseria gonorrhoeae, Hepatitis B virus, Influenza virus, respiratory syncytial virus, Hand-foot-and-mouth disease, and Tetanus.",

Two quality-control mechanisms, the ubiquitin proteasome system (UPS) and the release of mitochondria-derived vesicles, safeguard mitochondrial proteostasis. However, whether these processes interact is unknown. Here we show that the E3 ligase CRL5 Ozz , a member of the UPS, and its substrate Alix control the mitochondrial concentration of Slc25A4, a solute carrier that is essential for ATP production. The mitochondria in Ozz -/- or Alix -/- skeletal muscle share overt morphologic alterations (they are supernumerary, swollen, and dysmorphic) and have abnormal metabolomic profiles. We found that CRL5 Ozz ubiquitinates Slc25A4 and promotes its proteasomal degradation, while Alix facilitates SLC25A4 loading into exosomes destined for lysosomal destruction. The loss of Ozz or Alix offsets steady-state levels of Slc25A4, which disturbs mitochondrial metabolism and alters muscle fiber composition. These findings reveal hitherto unknown regulatory functions of Ozz and Alix in mitochondrial proteostasis.",

WW domain binding protein-2 (WBP2), a molecular chaperon, is involved in the progression of various malignancies, but its role in renal injuries has not been investigated. Our present study employed bioinformatics analysis to identify WBP2 as a potential modulator of AKI and ferroptosis. Preliminary laboratory investigations showed that WBP2, highly expressed in renal proximal tubular cells, was downregulated in CP-AKI. Further studies demonstrated that WBP2 decelerated ferroptosis to alleviate CP-AKI. Mechanistically, WBP2 interacted with glutathione peroxidase 4 (GPX4, a key detoxicating enzyme for ferroptosis) via its PPXY1 motif to inhibit ferroptosis. Furthermore, the in-depth investigations revealed that WBP2 competed with heat shock cognate protein 70 (HSC70) for the binding with the KEFRQ-like motifs of GPX4, leading to the deceleration of chaperon-mediated autophagy of GPX4. All in all, this study indicated the beneficial effect of WBP2 in CP-AKI and its relevance with ferroptosis, thus providing a novel insight into the modulation of ferroptosis in cisplatin-related nephropathy.",

The COVID-19 pandemic has led to significant use of coding therapeutic nucleic acids (cTNAs) in terms of DNA and mRNA in the development of vaccines. The use of cTNAs resulted in a paradigm shift in the therapeutic field. However, the injection of DNA or mRNA into the human body transforms cells into biological factories to produce the necessary proteins. Despite the success of cTNAs in the production of corona vaccines, they have several limitations such as instability, inability to cross biomembranes, immunogenicity, and the possibility of integration into the human genome. The chemical modification and utilization of smart drug delivery cargoes resolve cTNAs therapeutic problems. The success of cTNAs in corona vaccine production provides perspective for the eradication of influenza viruses, Zika virus, HIV, respiratory syncytial virus, Ebola virus, malaria, and future pandemics by quick vaccine design. Moreover, the progress cTNAs technology is promising for the development of therapy for genetic disease, cancer therapy, and currently incurable diseases.",
"37612326": "ID: 37612326\nTitle: Capsaicin binds the N-terminus of Hsp90, induces lysosomal degradation of Hsp70, and enhances the anti-tumor effects of 17-AAG (Tanespimycin).\nAbstract: Heat shock protein 90 (Hsp90) and its co-chaperones promote cancer, and targeting Hsp90 holds promise for cancer treatment. Most of the efforts to harness this potential have focused on targeting the Hsp90 N-terminus ATP binding site. Although newer-generation inhibitors have shown improved efficacy in aggressive cancers, induction of the cellular heat shock response (HSR) by these inhibitors is thought to limit their clinical efficacy. Therefore, Hsp90 inhibitors with novel mechanisms of action and that do not trigger the HSR would be advantageous. Here, we investigated the mechanism by which capsaicin inhibits Hsp90. Through mutagenesis, chemical modifications, and proteomic studies, we show that capsaicin binds to the N-terminus of Hsp90 and inhibits its ATPase activity. Consequently, capsaicin and its analogs inhibit Hsp90 ATPase-dependent progesterone receptor reconstitution in vitro. Capsaicin did not induce the HSR, instead, it promoted the degradation of Hsp70 through the lysosome-autophagy pathway. Remarkably, capsaicin did not induce degradation of the constitutively expressed cognate Hsc70, indicating selectivity for Hsp70. Combined treatments of capsaicin and the Hsp90 inhibitor 17-AAG improved the anti-tumor efficacy of 17-AAG in cell culture and tridimensional tumor spheroid growth assays using breast and prostate cancer models. Consistent with this, in silico docking studies revealed that capsaicin binding to the ATP binding site of Hsp90 was distinct from classical N-terminus Hsp90 inhibitors, indicating a novel mechanism of action. Collectively, these findings support the use of capsaicin as a chemical scaffold to develop novel Hsp90 N-terminus inhibitors as well as its ability to be a potential cancer co-therapeutic.",

The origin of synaptic A\u03b2 aggregates remains elusive, but loss of endosomal proteostasis may trigger their formation. In this study, we identified the synaptic compartments where A\u03b2 accumulates, and performed a longitudinal analysis of synaptosomes isolated from brains of TgCRND8 APP transgenic mice of either sex. To evaluate the specific contribution of A\u03b2-degrading protease endothelin-converting enzyme (ECE-1) to synaptic/endosomal A\u03b2 homeostasis, we analyzed the effect of partial Ece1 KO in brain and complete ECE1 KO in SH-SY5Y cells. Global inhibition of ECE family members was used to further assess their role in preventing synaptic A\u03b2 accumulation. Results showed that, before extracellular amyloid deposition, synapses were burdened with detergent-soluble A\u03b2 monomers, oligomers, and fibrils. Levels of all soluble A\u03b2 species declined thereafter, as A\u03b242 turned progressively insoluble and accumulated in A\u03b2-producing synaptic endosomal vesicles with characteristics of multivesicular bodies. Accordingly, fibrillar A\u03b2 was detected in brain exosomes. ECE-1-deficient mice had significantly increased endogenous synaptosomal A\u03b242 levels, and protease inhibitor experiments showed that, in TgCRND8 mice, synaptic A\u03b242 became nearly resistant to degradation by ECE-related proteases. Our study supports that A\u03b2 accumulating in synapses is produced locally, within endosomes, and does not require the presence of amyloid plaques. ECE-1 is a determinant factor controlling the accumulation and fibrillization of nascent A\u03b2 in endosomes and, in TgCRND8 mice, A\u03b2 overproduction causes rapid loss of A\u03b242 solubility that curtails ECE-mediated degradation.SIGNIFICANCE STATEMENT Deposition of aggregated A\u03b2 in extracellular plaques is a defining feature of AD. A\u03b2 aggregates also accumulate in synapses and may contribute to the profound synaptic loss and cognitive dysfunction typical of the disease. However, it is not clear whether synaptotoxic A\u03b2 is mainly derived from plaques or if it is produced and aggregated locally, within affected synaptic compartments. Filling this knowledge gap is important for the development of an effective treatment for AD, as extracellular and intrasynaptic pools of A\u03b2 may not be equally modulated by immunotherapies or other therapeutic approaches. In this manuscript, we provide evidence that A\u03b2 aggregates building up in synapses are formed locally, within synaptic endosomes, because of disruptions in nascent A\u03b2 proteostasis.",

PD is characterized by the degeneration of dopaminergic neurons in the substantia nigra pars compacta and this correlates with the accumulation of misfolded \u03b1-synuclein. While the aggregation of \u03b1-synuclein in the form of Lewy bodies or Lewy neurites is a well-established intraneuronal hallmark of the disease process, our understanding of the glial contribution to aberrant \u03b1-synuclein proteostasis is lacking. In this regard, restoring astrocyte function during early PD could offer a promising therapeutic avenue and understanding the involvement of astrocytes in handling/mishandling of \u03b1-synuclein is of particular interest. Here, we explore the growing body of scientific literature implicating aberrant astrocytic \u03b1-synuclein proteostasis with the seemingly inexorable pathological sequelae typifying PD. We also provide a perspective on how heterogeneity in the morphological relationship between astrocytes and neurons will need to be considered in the context of PD pathogenesis.",
"38035334": "ID: 38035334\nTitle: Extracellular vesicle storm during the course of Ebola virus infection in primates.\nAbstract: Ebola virus (EBOV) is an RNA virus of the Filoviridae family that is responsible for outbreaks of hemorrhagic fevers in primates with a lethality rate as high as 90%. EBOV primarily targets host macrophages leading to cell activation and systemic cytokine storm, and fatal infection is associated with an inhibited interferon response, and lymphopenia. The EBOV surface glycoprotein (GP) has been shown to directly induce T cell depletion and can be secreted outside the virion via extracellular vesicles (EVs), though most studies are limited to epithelial cells and underlying mechanisms remain poorly elucidated. To assess the role of GP on EBOV-induced dysregulation of host immunity, we first utilized EBOV virus-like particles (VLPs) expressing VP40 and NP either alone (Bald-VLP) or in conjunction with GP (VLP-GP) to investigate early inflammatory responses in THP-1 macrophages and in a murine model. We then sought to decipher the role of non-classical inflammatory mediators such as EVs over the course of EBOV infection in two EBOV-infected rhesus macaques by isolating and characterizing circulatory EVs throughout disease progression using size exclusion chromatography, nanoparticle tracking-analysis, and LC-MS/MS. While all VLPs could induce inflammatory mediators and recruit small peritoneal macrophages, pro-inflammatory cytokine and chemokine gene expression was exacerbated by the presence of GP. Further, quantification of EVs isolated from infected rhesus macaques revealed that the concentration of vesicles peaked in circulation at the terminal stage, at which time EBOV GP could be detected in host-derived exosomes. Moreover, comparative proteomics conducted across EV populations isolated from serum at various time points before and after infection revealed differences in host-derived protein content that were most significantly pronounced at the endpoint of infection, including significant expression of mediators of TLR4 signaling. These results suggest a dynamic role for EVs in the modification of disease states in the context of EBOV. Overall, our work highlights the importance of viral factors, such as the GP, and host derived EVs in the inflammatory cascade and pathogenesis of EBOV, which can be collectively further exploited for novel antiviral development.",

The internal cargo of EVs is protected from degradation, making EVs attractive AD biomarkers. However, it is unclear how circulating EVs relate to EVs isolated from disease-vulnerable brain regions. We developed a novel method for collecting EVs from the hippocampal interstitial fluid (ISF) of live mice. EVs (EVISF ) were isolated via ultracentrifugation and characterized by nanoparticle tracking analysis, immunogold labelling, and flow cytometry. Mass spectrometry and proteomic analyses were performed on EVISF cargo. EVISF were 40-150\u00a0nm in size and expressed CD63, CD9, and CD81. Using a model of cerebral amyloidosis (e.g., APPswe, PSEN1dE9 mice), we found protein concentration increased but protein diversity decreased with A\u03b2 deposition. Genotype, age, and A\u03b2 deposition modulated proteostasis- and immunometabolic-related pathways. Changes in the microglial EVISF proteome were sexually dimorphic and associated with a differential response of plaque associated microglia. We found that female APP/PS1 mice have more amyloid plaques, less plaque associated microglia, and a less robust- and diverse- EVISF microglial proteome. Thus, in vivo microdialysis is a novel technique for collecting EVISF and offers a unique opportunity to explore the role of EVs in AD.",

The involvement of C. albicans secretome on host biological processes has been demonstrated. However, the immunoregulatory function of C. albicans secretome released under hypoxic condition remains unclear. This study demonstrated the differences in cytokine responses and protein profiles between secretomes prepared under normoxic and hypoxic conditions. Furthermore, the immunoregulatory effects of heat shock protein SSA1(Ssa1), a protein candidate enriched in the hypoxic secretome, were investigated. Stimulation of mouse bone marrow-derived macrophages (BMMs) with Ssa1 resulted in the significant production of interleukin (IL)-10, IL-6, and tumor necrosis factor (TNF)-\u03b1 as well as the significant expression of M2b macrophage markers (CD86, CD274 and tumor necrosis factor superfamily member 14), suggesting that C. albicans Ssa1 may promote macrophage polarization towards an M2b-like phenotype. Proteomic analysis of Ssa1-treated BMMs also revealed that Ssa1 reduced inflammation-related factors (IL-18-binding protein, IL-1 receptor antagonist protein, OX-2 membrane glycoprotein and cis-aconitate decarboxylase) and enhanced the proteins involved in anti-inflammatory response (CMRF35-like molecule 3 and macrophage colony-stimulating factor 1 receptor). Based on these results, we investigated the effect of Ssa1 on C. albicans infection and showed that Ssa1 inhibited the uptake of C. albicans by BMMs. Taken together, our results suggest that C. albicans alters its secretome, particularly by promoting the release of Ssa1, to modulate host immune response and survive under hypoxic conditions.",

While most of AML therapies are focused toward tumor debulking, all-trans retinoic acid (ATRA) induces neutrophil differentiation in the AML subtype acute promyelocytic leukemia (APL). Macroautophagy has been extensively investigated in the context of various cancers and is often dysregulated in AML where it can have context-dependent pro- or anti-leukemogenic effects. On the contrary, the implications of chaperone-mediated autophagy (CMA) on the pathophysiology of diseases are still being explored and its role in AML remains elusive. We took advantage of human AML primary samples and databases to analyze CMA gene expression and activity. Furthermore, we used ATRA-sensitive (NB4) and -resistant (NB4-R1) APL cells to further dissect a potential function for CMA in ATRA-mediated neutrophil differentiation. NB4-R1 cells are unique in that they do respond to retinoic acid transcriptionally but do not mature in response to retinoid signaling alone unless maturation is triggered by adding cyclic adenosine monophosphate. Here, we report that CMA-related mRNA transcripts are significantly higher expressed in immature hematopoietic cells as compared to neutrophils, contrasting the macroautophagy gene expression patterns. Accordingly, lysosomal degradation of an mCherry-KFERQ CMA reporter decreases during ATRA-induced differentiation of APL cells. On the other hand, using NB4-R1 cells we found that macroautophagy flux primed ATRA-resistant NB4-R1 cells to differentiate upon ATRA treatment but reduced the association of lysosome-associated membrane protein type 2A (LAMP-2A) and heat shock protein family A (Hsp70) member 8 (HSPA8), necessary for complete neutrophil maturation. Accordingly, depletion of HSPA8 attenuated CMA activity and facilitated APL cell differentiation. In contrast, maintaining high CMA activity by ectopic expression of LAMP-2A impeded APL differentiation. Overall, our findings suggest that APL neutrophil differentiation requires CMA inactivation and that this pathway predominantly depends on HSPA8 and is possibly assisted by other co-chaperones.",

Here, we show yeast transmit information through the extracellular medium that increases survival when confronted with heat stress and demonstrate the EV-enriched samples mediate this thermotolerance transfer. These samples contain vesicle-like particles that are exosome-sized and disrupting exosome biogenesis by targeting endosomal sorting complexes required for transport (ESCRT) machinery inhibits thermotolerance transfer. We find that Bro1, the yeast ortholog of the human exosome biomarker ALIX, is present in EV samples, and use Bro1 tagged with green fluorescent protein (GFP) to track EV release and uptake by endocytosis. Proteomics analysis reveals that heat shock protein 70 (HSP70) family proteins are enriched in EV samples that provide thermotolerance. We confirm the presence of the HSP70 ortholog stress-seventy subunit A2 (Ssa2) in EV samples and find that mutant yeast cells lacking SSA2 produce EVs but they fail to transfer thermotolerance. We conclude that Ssa2 within exosomes shared between yeast cells contributes to thermotolerance. Through this work, we advance Saccharomyces cerevisiae as an emerging model organism for elucidating molecular details of eukaryotic EV biology and establish a role for exosomes in heat stress and proteostasis that seems to be evolutionarily conserved.",

PROTACs excel at specifically degrading pathogenic proteins, offering a targeted and efficient antiviral strategy. We also investigate the potential of exosome-based diagnostic technologies, which harness cell-derived nanovesicles for non-invasive sampling and early viral infection detection. Addressing the challenge of PROTAC delivery, we introduce a groundbreaking strategy utilizing exosomes to deliver PROTACs with improved precision and as a targeted delivery vehicle. Integrating these innovative strategies provides a novel approach to combat RNA zoonotic viral diseases, paving the way for a new era in antiviral therapy.",

In this study, affinity tag-purification mass spectrometry was employed to delineate RABV glycoprotein and host protein interactions, and PDIA3/ERP57 was identified as a potential inhibitor of RABV infection. PDIA3 restricted RABV infection with follow mechanisms: PDIA3 mediated the degradation of RABV G protein by targeting lysine 332 via the selective macroautophagy/autophagy pathway; The PDIA3 interactor, AP3B1 (adaptor related protein complex 3 subunit beta 1) was indispensable in PDIA3-triggered selective degradation of the G protein; Furthermore, PDIA3 competitively bound with NCAM1/NCAM (neural cell adhesion molecule 1) to block RABV G, hindering viral entry into host cells. PDIA3 190-199 aa residues bound to the RABV G protein were necessary and sufficient to defend against RABV.

Emerging from CSCs, the exosomes serve as pivotal mediators of intercellular communication within the tumor microenvironment, modulating invasion, angiogenesis, and immune responses. Moreover, CSC-derived exosomes play a central role in sculpting a dynamic landscape, contributing to the malignant phenotype. Amidst several exosomal cargoes, misfolded proteins have recently gained attention for their dual functions in maintaining protein homeostasis and promoting tumor progression. Disrupting these communication pathways could potentially prevent the maintenance and expansion of CSCs, overcome treatment resistance, and inhibit the supportive environment created by the tumor microenvironment, thereby improving the effectiveness of cancer therapies and reducing the risk of tumor recurrence and metastasis. Additionally, exosomes have also shown potential therapeutic applications, such as in drug delivery or as biomarkers for cancer diagnosis and prognosis. Therefore, comprehending the biology of exosomes derived from CSCs is a multifaceted area of research with implications in both basic sciences and clinical applications. This review explores the intricate interplay between exosomal misfolded proteins released by CSCs, the potent contributor in tumor heterogeneity, and their impact on cellular processes, shedding light on their role in cancer progression.",

Essential Oil Exhibits Antiviral Activity against Coronaviruses.\nAbstract: Human coronaviruses are a continuous threat to the human population and have limited antiviral treatments, and the recent COVID-19 pandemic sparked interest in finding new antiviral strategies, such as natural products, to combat emerging coronaviruses. Rapid efforts in the scientific community to identify effective antiviral agents for coronaviruses remain a focus to minimize mortalities and global setbacks. In this study, an essential oil derived from Myrtus communis L. (MEO) is effective against HCoV-229E and HCoV-OC43 virus infections in comparison to two FDA-approved drugs, Remdesivir and Nirmatrelvir. Gas-chromatography and mass spectrometry were used to identify the chemical composition of MEO. Slight antioxidant activity was observed in MEO, indicating a role in oxidative stress. A dose-response curve measuring the EC50 indicates a high potency against HCoV-229E and HCoV-OC43 virus infections on Huh7.5 cells with low cytotoxicity using a PrestoBlue cell viability assay. Our findings demonstrate that MEO exhibits potent antiviral activity against HCoV-229E and HCoV-OC43 on Huh7.5 cells within a low-cytotoxicity range, but not on SARS-CoV-2. Artificial bacterial chromosome plasmids that expressed SARS-CoV-2 used for replicon-to determine viral replication and viral assembly/egress on HEK293T/17 cells-and virus-like particles on Huh7.5-AT cells-to determine viral entry and assembly/egress-showed no antiviral activity with MEO in comparison to Remdesivir. This study reveals the potential effectiveness of MEO as an alternative natural remedy to treat human coronaviruses and a potential antiviral agent for future coronavirus infections.",

An investigation into the roles of spices essential oils (EO) on inflammatory cytokines, HSP70 and oxidative markers of broiler chickens was conducted in this study. Four spices consisting of garlic, ginger, turmeric, and cinnamon were processed to obtain their respective EO. Two hundred 1-d-old arbo acre broilers were allotted to 5 treatments consisting of B1 (control), B2 (garlic EO), B3 (ginger EO), B4 (Turmeric EO), and B5 (cinnamon EO), with EOs administered to drinking water at 30% (v/v) in a 49-d trial. Blood was sampled for assessment of hematological parameters, and serum obtained were assayed for inflammatory cytokines, antioxidant activities, nuclear factor kappa B (NF\u03baB), 8-hydroxydeoxyguanosine (8-OHdG), and heat shock protein 70 (HSP70) levels using standard procedures. Results obtained revealed that cinnamon EO enhanced erythrocytic indices, leukocyte profile, catalase, glutathione peroxidase and interleukin 10, lowers interleukin 1 beta (IL-1\u03b2) and interferon gamma (IFN-\u03b3), enhanced HSP70 and higher 8-OHdG levels in chicken. Garlic EO enhanced monocytes and superoxide dismutase, while reduced IFN-\u03b3 and HSP70, but increased IL-1\u03b2 and tumor necrosis factor alpha (TNF-\u03b1) NF\u03baB in broiler chickens. Ginger EO also enhanced erythrocytic indices, total antioxidant activity, lowered IFN-\u03b3 and lipid peroxidation, while turmeric EO enhanced total antioxidant activity, catalase and lowered IFN-\u03b3 and increased 8ohdg in broiler chickens. In conclusion, this study revealed that ginger and turmeric EO were more beneficial in preventing oxidative DNA damage, cinnamon EO enhanced serum oxidative status and lowered pro-inflammatory cytokines, while garlic EO reduced HSP70 in broiler chickens.",

Reliable prognostic markers and treatments to enhance liver regeneration are lacking. Plasma nanoparticles, including lipoproteins, exosomes, and extracellular vesicles (EVs), can reflect systemic and tissue-wide proteostasis and stress, potentially aiding liver regeneration. However, their role in PHLF is still unknown. Our study included nine patients with hepatocellular carcinoma (HCC) undergoing PHx: three patients with PHLF, three patients undergoing the associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) procedure, and three matched controls without complications after PHx. Patient plasma was collected before PHx as well as 1 and 5 days after. EVs were isolated by ultracentrifugation, and extracted proteins were subjected to quantitative mass spectrometry using a super-SILAC mix prepared from primary and cancer cell lines. We identified 2625 and quantified 2570 proteins in the EVs of PHx patients. Among these, 53 proteins were significantly upregulated and 32 were downregulated in patients with PHLF compared to those without PHLF. Furthermore, 110 proteins were upregulated and 78 were downregulated in PHLF patients compared to those undergoing ALPPS. The EV proteomic signature in PHLF indicates significant disruptions in protein translation, proteostasis, and intracellular vesicle biogenesis, as well as alterations in proteins involved in extracellular matrix (ECM) remodelling and the metabolic and cell cycle pathways, already present before PHx. Longitudinal proteomic analysis of the EVs circulating in the plasma of human patients undergoing PHx uncovers proteomic signatures associated with PHLF, which reflect dying hepatocytes and endothelial cells and were already present before PHx.",
"39427885": "ID: 39427885\nTitle: Mitochondria break free: Mitochondria-derived vesicles in aging and associated conditions.\nAbstract: Mitophagy is the intracellular recycling system that disposes damaged/inefficient mitochondria and allows biogenesis of new organelles to ensure mitochondrial quality is optimized. Dysfunctional mitophagy has been implicated in human aging and diseases. Multiple evolutionarily selected, redundant mechanisms of mitophagy have been identified, but their specific roles in human health and their potential exploitation as therapeutic targets are unclear. Recently, the characterization of the endosomal-lysosomal system has revealed additional mechanisms of mitophagy and mitochondrial quality control that operate via the production of mitochondria-derived vesicles (MDVs). Circulating MDVs can be isolated and characterized to provide an unprecedented opportunity to study this type of mitochondrial recycling in vivo and to relate it to human physiology and pathology. Defining the role of MDVs in human physiology, pathology, and aging is hampered by the lack of standardized methods to isolate, validate, and characterize these vesicles. Hence, some basic questions about MDVs remain unanswered. While MDVs are generated directly through the extrusion of mitochondrial membranes within the cell, a set of circulating extracellular vesicles leaking from the endosomal-lysosomal system and containing mitochondrial portions have also been identified and warrant investigation. Preliminary research indicates that MDV generation serves multiple biological roles and contributes to restoring cell homeostasis. However, studies have shown that MDVs may also be involved in pathological conditions. Therefore, further research is warranted to establish when/whether MDVs are supporting disease progression and/or are extracting damaged mitochondrial components to alleviate cellular oxidative burden and restore redox homeoastasis. This information will be relevant for exploiting these vesicles for therapeutic purpose. Herein, we provide an overview of preclinical and clinical studies on MDVs in aging and associated conditions and discuss the interplay between MDVs and some of the hallmarks of aging (mitophagy, inflammation, and proteostasis). We also outline open questions on MDV research that should be prioritized by future investigations.",

Promoting the degradation of misfolded proteins has been shown to be an effective approach to alleviate PD. This review highlights the roles of specific heat shock proteins (HSPs) in modulating \u03b1-syn aggregation and neuronal survival. HSP27 prevents glycosylation-induced \u03b1-syn aggregation, disrupts copper ion interactions, inhibits mitochondrial apoptosis, and prevents dopaminergic neuronal cell death. HSP70 alleviates dopaminergic neuronal damage by promoting mitophagy and preventing neuronal apoptosis. HSC70 plays a critical role in chaperone-mediated autophagy and facilitates lysosomal degradation. GRP78 mitigates abnormal protein aggregation. The HSP70-HSP40-HSP110 system is capable of degrading \u03b1-syn amyloid fibers. Inhibition of HSP90 expression protects neurons. Further research should prioritize developing regulators of HSPs as treatments for PD. While HSPs offer promise in PD management, their complex roles necessitate cautious therapeutic development to harness their potential. Understanding the specific roles of different HSPs will be essential to developing effective therapies for \u03b1-syn clearance.",
"39611307": "ID: 39611307\nTitle: Impaired chaperone-mediated autophagy leads to abnormal SORT1 (sortilin 1) turnover and CES1-dependent triglyceride hydrolysis.\nAbstract: SORT1 (sortilin 1), a member of the the Vps10 (vacuolar protein sorting 10) family, is involved in hepatic lipid metabolism by regulating very low-density lipoprotein (VLDL) secretion and facilitating the lysosomal degradation of CES1 (carboxylesterase 1), crucial for triglyceride (TG) breakdown in the liver. This study explores whether SORT1 is targeted for degradation by chaperone-mediated autophagy (CMA), a selective protein degradation pathway that directs proteins containing KFERQ-like motifs to lysosomes via LAMP2A (lysosomal-associated membrane protein 2A). Silencing LAMP2A or HSPA8/Hsc70 with siRNA increased cytosolic SORT1 protein levels. Leupeptin treatment induced lysosomal accumulation of SORT1, unaffected by siLAMP2A co-treatment, indicating CMA-dependent degradation. Human SORT1 contains five KFERQ-like motifs (658VVTKQ662, 730VREVK734, 733VKDLK737, 734KDLKK738, and 735DLKKK739), crucial for HSPA8 recognition; mutating any single amino acid within these motifs decreased HSPA8 binding. Furthermore, compromised CMA activity resulted in elevated SORT1-mediated degradation of CES1, contributing to increased lipid accumulation in hepatocytes. Consistent with in vitro findings, LAMP2A knockdown in mice exacerbated high-fructose diet-induced fatty liver, marked by increased SORT1 and decreased CES1 levels. Conversely, LAMP2A overexpression promoted SORT1 degradation and CES1D accumulation, counteracting fasting-induced CES1D suppression through CMA activation. Our findings reveal that SORT1 is a substrate of CMA, highlighting its crucial role in directing CES1 to lysosomes. Consequently, disrupting CMA-mediated SORT1 degradation significantly affects CES1-dependent TG hydrolysis, thereby affecting hepatic lipid homeostasis.Abbreviations: APOB: apolipoprotein B; CES1: carboxylesterase 1; CMA: chaperone-mediated autophagy; HSPA8/Hsc70: heat shock protein family A (Hsp70) member 8; LAMP2A: lysosomal associated membrane protein 2A; LDL-C: low-density lipoprotein-cholesterol; PLIN: perilipin; SORT1: sortilin 1; TG: triglyceride; VLDL: very low-density lipoprotein; Vps10: vacuolar protein sorting 10.",
"39677700": "ID: 39677700\nTitle: Investigating the potential role of capsaicin in facilitating the spread of coxsackievirus B3 via extracellular vesicles.\nAbstract: Coxsackievirus B3 (CVB3) is a non-enveloped picornavirus that can cause systemic inflammatory diseases including myocarditis, pericarditis, pancreatitis, and meningoencephalitis. We have previously reported that following infection, CVB3 localizes to mitochondria, inducing mitochondrial fission and mitophagy, while inhibiting lysosomal degradation by blocking autophagosome-lysosome fusion. This results in the release of virus-laden mitophagosomes from the host cell as infectious extracellular vesicles (EVs) which allow non-lytic viral egress. Transient receptor potential vanilloid 1 (TRPV1/ TRPV1 ) is a heat and capsaicin-sensitive cation channel that regulates mitochondrial dynamics by inducing mitochondrial membrane depolarization and fission. In this study, we found that treating cells with the TRPV1 agonist capsaicin dramatically enhances CVB3 egress via EVs. Analysis of the released EVs revealed increased levels of viral capsid protein VP1/ VP1 , mitochondrial protein TOM70/ TOMM70 , and fission protein phospho-DRP1/ DNM1L (Ser 616). Moreover, these EVs exhibited increased levels of heat shock protein HSP70/ HSPA1A , suggesting a potential role of these chaperones in facilitating infectious EV release from cells. Furthermore, TRPV1 inhibition with capsazepine significantly reduced viral infection in vitro . We previously observed similar effects in vitro with another TRPV1 inhibitor SB-366791. Our current in vivo studies found that SB-366791 significantly mitigates pancreatic damage and reduces viral titers in mouse model of CVB3 pancreatitis. Given the lack of understanding regarding the factors that contribute to diverse clinical manifestations of CVB3, our study highlights capsaicin and TRPV1 as potential exacerbating factors that facilitates CVB3 dissemination via mitophagy-derived EVs. CVB3 is a prevalent pathogen responsible for a range of severe diseases, including myocarditis, pericarditis, pancreatitis, and meningoencephalitis. Despite its clinical significance, factors that determine the severity of CVB3 infection and why some individuals experience life-threatening manifestations while others have mild, cold-like symptoms remain poorly understood. This study provides new insights into the molecular mechanisms underlying CVB3 dissemination and pathogenesis. By investigating the role of capsaicin, a common dietary component, in modulating viral spread, we demonstrate that activation of TRPV1 by capsaicin enhances release of infectious CVB3 via mitophagy-derived EVs. Our results offer novel evidence that modulating TRPV1 activity could influence the clinical outcomes of CVB3 infection, opening new avenues for therapeutic interventions. Given the widespread consumption of capsaicin, this study highlights an important dietary factor that could play a role in shaping CVB3 pathogenesis and its clinical manifestations, underscoring the potential for targeted strategies to mitigate severe disease outcomes.",

These hallmarks play a crucial role in the aging process. Despite their intricate interconnections, the relationships among the hallmarks of aging remain unclear. Although the boundaries between these hallmarks may be indistinct, they exhibit interdependence, with the influence of one hallmark extending to others. Building on this foundation, we investigated the interrelations among the various hallmarks of aging and provided a systematic overview of their logical relationships, proposing that cellular communication plays a crucial role in the aging process. Exosomes function as a primary mode of cellular communication and significantly impact the aging process. Therefore, we propose utilizing exosomes as valuable tools for understanding the mechanisms of aging and addressing age-related concerns. Exosomes may represent a novel approach for the treatment and diagnosis of aging-related conditions in animals. Furthermore, our research reveals that exocytosis in young nematodes slows the aging process, while exocytosis in aged nematodes has the opposite effect, accelerating aging. In conclusion, exosomes act as intercellular messengers that influence the maintenance of a healthy aging process and link the hallmarks of aging with indicators of well-being.",

In total, 640 1-day-old male chicks were randomly assigned to five experimental diets (eight replicates/treatment, 16 birds/replicate). Diets included a basal diet with no added vitamin E (NC), NC plus 100 ppm of vitamin E (PC), NC plus 1250 ppm of OE, NC plus 250 ppm of (SPICY), and NC plus 1250 ppm OE plus 250 ppm of SPICY (SPIOE). Phytogenic additives were supplied by Lucta S.A., Spain. Compared to the NC, the PC significantly (p < 0.05) increased ADG from 8 to 14 days of age, with both OE and SPICY showing intermediate values between both controls. At the end of this trial, at 35 days of age, a significant (p < 0.05) increase in plasma GPx activity was observed in PC-fed birds compared to the NC, with no effects of malonyl dialdehyde (MDA) and total antioxidant capacity. Birds fed the OE and SPICY displayed intermediate values of GPx activity compared to both controls. The expression of heat shock protein 70 (HSP70) and glutathione S-Transferase Alpha 4 (GSTA4) was significantly lower (p < 0.05) in the jejunal mucosa of birds fed the OE compared to the NC. Moreover, the expression of HSP70 was significantly lower (p < 0.05) in birds fed the OE compared to SPICY but was not significantly different compared to the blend of both extracts (SPIOE). In conclusion, OE and SPICY were useful in maintaining growth performance in no vit E-supplemented diets, particularly in the case of OE mediated by its antioxidant action through HSP70.",

This study aimed to investigate the effects of Bangle extract (BaE) on inflammation and autophagy in the colons of mice with dextran sulfate sodium (DSS)-induced colitis. Male C57BL/6J mice were assigned to four groups: control, DSS\u00a0+\u00a00% BaE, DSS\u00a0+\u00a01% BaE, and DSS\u00a0+\u00a03% BaE. The BaE groups were fed BaE diets for 3 weeks, followed by an additional week of BaE diets and 3% DSS in the water. The control group received a standard chow diet and water for 4 weeks.

However, there are still no effective antiviral therapies that can completely cure EVD. A comprehensive understanding of virus-host interactions would be beneficial for developing new antiviral agents. Here, we showed that CXCR4-induced macroautophagy/autophagy and was internalized to endosomes by interacting with glycoprotein (GP) on viral particles during EBOV infection; this promoted the EBOV attachment and entry, which was reduced by CXCR4 antagonist and neutralizing antibody. We also found that CXCR4 increased EBOV replication by downregulating cytotoxic GP to promote viral fitness instead of influencing the assembly of viral factory. Mechanistically, excessive EBOV GP could hijack CXCR4 sorting and transporting pathways by their interactions with HGS, one of the key components of the ESCRT machinery; subsequently GP could be carried back to the endoplasmic reticulum by CXCR4, where the E3 ubiquitin ligase RNF185 was recruited to polyubiquitinate GP in a K27- and K63-linked manner. Finally, polyubiquitinated GP was degraded in lysosomes via reticulophagy by interacting with RETREG1 (reticulophagy regulator 1), in an ATG3- and ATG5-dependent manner. Our findings revealed dual roles of CXCR4 in regulation of EBOV life cycle, either acting as an entry factor by interacting with GP on viral particles to facilitate viral entry or targeting excessive GP for reticulophagic degradation, providing new evidence that EBOV hijacked the host vesicular transportation system through efficient virus-host interactions to facilitate viral fitness.Abbreviations: Baf A1: bafilomycin A1; BDBV: Bundibugyo Ebolavirus; CHX: cycloheximide; CXCR4: C-X-C motif chemokine receptor 4; CLEC4M/DC-SIGNR: C type lectin domain family 4 member M; EBOV: Zaire Ebolavirus; EEA1: early endosome antigen 1; ER: endoplasmic reticulum; ERAD: ER-associated degradation; ESCRT: endosomal sorting complex required for transport; EVD: Ebolavirus disease; HAVCR1/TIM-1: hepatitis A virus cellular receptor 1; GP: glycoprotein; HGS: hepatocyte growth factor-regulated tyrosine kinase substrate; HIV: human immunodeficiency virus; IFL: internal fusion loop; ITCH/AIP4: itchy E3 ubiquitin protein ligase; LAMP: lysosomal associated membrane protein; LC-MS/MS: liquid chromatography mass spectrometry; PDIs: protein disulfide isomerases; RBD: receptor binding domain; RESTV: Reston Ebolavirus; RETREG1: reticulophagy regulator 1; RNF185: ring finger protein 185; SQSTM1/p62: sequestosome 1; SUDV: Sudan Ebolavirus; TAFV: Ta\u00ef Forest Ebolavirus; TRIM21: tripartite motif containing 21; trVLPs: transcription- and replication-competent virus-like particles; Ub: ubiquitin.",

Intracellular nanovesicles (INVs) are a large and molecularly heterogenous family of uncoated transport vesicles, which are comprised of multiple subtypes. As a step to characterizing these subtypes, we recently published the first INV proteome and were intrigued by the enrichment of ATG9A in it. ATG9A is the only conserved transmembrane protein with a core function in macroautophagy/autophagy, and it is found on small, uncoated vesicles, termed \"ATG9A-positive vesicles\". We therefore, set out to disambiguate the relationship between these two types of vesicular carriers in cells. We showed that ATG9A-containing vesicles, rather than being a distinct vesicle class, represent one subset of the INV family. We also demonstrated that this relationship is functionally important and that perturbing INV-mediated trafficking impeded starvation-induced autophagy. Here, we briefly introduce INVs, summarize the evidence supporting our definition of ATG9A-flavor INVs and present our outlook on why we hope that this classification will help to consolidate efforts to understand the functions of these vesicles in autophagy and beyond.",

Increasing evidence suggests that Hsp70 decides the fate of proteins; however, the inherent rules that govern the decision-making capacity of Hsp70 are not clear. In this review, we have articulated the functions of Hsp70 with respect to proteostasis and established a link between its co-chaperones in deciding the fate of the substrate. The substrate binding of Hsp70 is mediated by its catalytic cycle where Hsp70 achieves high- and low-substrate-affinity ADP- and ATP-bound forms, respectively. This catalytic cycle of Hsp70 is maintained by co-chaperones J-domain proteins (JDPs), and nucleotide exchange factors (NEFs). JDPs bind to the ATP-bound form of Hsp70 and hydrolyze ATP that enhances substrate binding, whereas NEFs exchange ADP with ATP and facilitate substrate release. During evolution, several isoforms of Hsp70 and its co-chaperones have emerged which may have functional significance. Apart from facilitating the catalytic cycle of Hsp70, co-chaperones often mediate collaboration between Hsp70 and downstream protein quality-control pathways such as the ubiquitin proteasome system, autophagy, or disaggregase machinery. Therefore, co-chaperones have a significant role in Hsp70's triage decision of whether to fold, hold, or degrade.",

Here, we report that a rhizosphere bacterium, Bacillus amyloliquefaciens strain TG1-2 displays antimicrobial activity against various phytopathogenic fungi and oomycetes, in a process that is mediated by the NatA acetyltransferase complex in the phytopathogenic fungus Verticillium dahliae. We show that acetylation of the molecular chaperone Hsp83 by NatA facilitates the formation of a co-chaperone complex Hsp83-Sti1-Hsp70 involved in protein quality control. Dysfunction of NatA or disruption of Hsp83 acetylation results in dissociation of the co-chaperon complex, increasing protein degradation and fungal apoptosis. Notably, TG1-2 and its major antimicrobial compound surfactin induce a reduction in Hsp83 acetylation, enhancing protein degradation and fungal apoptosis.

Initiation and attenuation of the response are mediated by stress-dependent regulation of heat shock transcription factors (HSFs). Saccharomyces cerevisiae encodes a single HSF (Hsf1), facilitating the analysis of HSR regulation. Hsf1 is repressed by Hsp70 chaperones under non-stress conditions, and becomes activated under proteotoxic stress, directly linking protein damage and its repair to the HSR. J-domain proteins (JDPs) are essential for targeting of Hsp70s to their substrates, yet the specific JDP(s) regulating Hsf1 and connecting protein damage to HSR activation remain unclear. Here we show that the yeast nuclear JDP Apj1 primarily controls the attenuation phase of the HSR by promoting Hsf1's displacement from heat shock elements in target DNA. In apj1\u0394 cells, HSR attenuation is significantly impaired. Additionally, yeast cells lacking both Apj1 and the major JDP Ydj1 exhibit increased HSR activation even in non-stress conditions, indicating their distinct regulatory roles. Apj1's role in both nuclear protein quality control and Hsf1 regulation underscores its role in directly linking nuclear proteostasis to HSR regulation. Together these findings establish the nucleus as key stress-sensing signaling hub.",

Based on the expression of an aggregation-prone protein in the mitochondrial matrix, we determined the effect of organelle dynamics on aggregate sequestration. Fusion-deficient cells were unable to accumulate the aggregates in the IMiQ, resulting in a stress-sensitive phenotype. In contrast, fission-deficient cells could not separate the aggregate from the mitochondrial network. In these mitochondria, the aggregates were neutralized by the formation of a shell formed by mitochondrial chaperones. We also performed quantitative mass spectrometry to analyse the mitochondrial proteome and the extent of co-aggregation of mitochondrial proteins. Although only minor changes of the total proteome were detected in response to aggregate accumulation, we found a recruitment of proteins of the respiratory chain complexes and of the protein quality control system (PQC). In particular, members of the Hsp70 chaperone family were prominently associated with the aggregate. We conclude that this chaperone-dependent neutralization prevents a major co-aggregation of endogenous mitochondrial proteins.",

This study extracted TLNVs from fresh tea leaves by ultracentrifugation and characterized them by transmission electron microscopy (TEM), nanoparticle tracking analysis (NTA) and secondary metabolites composition analysis. In vitro, TLNVs exhibited stronger radical scavenging ability and tyrosinase inhibitory effect than conventional tea leaf extract, while inhibiting B16-F10\u00a0cell proliferation and melanin synthesis. Based on these in vitro results, we further evaluated the anti-pigmentation effects of TLNVs in an uvB-induced pigmented mouse model, in which TLNVs markedly reduced epidermal melanin deposition and epidermal thickness while increasing dermal thickness and collagen volume fraction. TLNVs effectively suppressed the expression of inflammatory cytokines (TNF-\u03b1 and IL-1\u03b2) and promoted melanoautophagy by upregulating LC3B and downregulating P62. Moreover, confocal laser scanning microscopy (CLSM) analysis of fluorescently labeled TLNVs confirmed their penetration ability into the deep dermis, reaching approximately 200\u00a0\u03bcm. Mechanistic studies demonstrated that miR-828b in TLNVs directly targeted MYB4 via PI3K/AKT pathway and downregulated melanogenesis regulators such as MITF and TYR. to reduce melanin production. Overexpression of MYB4 reversed the inhibitory effects of miR-828b on melanogenesis, confirming the specificity of this regulatory axis. This study is the first to confirm that TLNVs, as natural nanomaterials, exert multifunctional properties in combating skin pigmentation through the miR-828b/MYB4 axis. These include antioxidation, anti-inflammation, and the promotion of autophagy activity. TLNVs with high transdermal permeability and low toxicity provide a safer strategy for coping with pigmented skin diseases and sustainable tea leaf resource utilization.",

One key mechanism eliminating protein aggregates is aggrephagy, a selective type of autophagy. Here we reveal that fragmentation is required before autophagic clearance of various types of amorphous aggregates. This fragmentation requires both the 19S proteasomal regulatory particle and the DNAJB6-HSP70-HSP110 chaperone module. These two players are also essential for aggregate compaction that leads to the clustering of the selective autophagy receptors, which initiates the autophagic removal of the aggregates. We also found that the same players delay the formation of disease-associated huntingtin inclusions. This study assigns a novel function to the 19S regulatory particle and the DNAJB6-HSP70-HSP110 module, and uncovers that aggrephagy entails a piecemeal process, with relevance for proteinopathies.",

Disruption of this quality control, particularly involving the ER chaperone GRP94, contributes to diseases such as hypercholesterolemia, cancer, and immune disorders, where defective GRP94-dependent folding and the trafficking of client proteins like PCSK9, integrins, and Toll-like receptors drive pathology. Here, we characterize NSC637153 (cp153), a small molecule identified in a drGFP-based ERAD dislocation screen, as a selective probe of GRP94-dependent processes. cp153 inhibits the dislocation of ERAD substrates, preferentially affecting luminal clients, increases PCSK9 secretion, and promotes LDLR degradation. Unlike ATP-competitive HSP90 inhibitors, cp153 does not induce HSP70 or destabilize AKT, suggesting that it perturbs GRP94 function by interfering with client interaction or folding. The identification of cp153 provides a useful tool to for probing GRP94's role in protein folding, trafficking, ER quality control, and disease-relevant signaling pathways, and supports the development of client-selective GRP94-targeted therapies.",

Among the treatments, microcapsules and the eugenol compound showed the best results, each achieving a 50% survival rate after 72 h. The microcapsule group provided prolonged antioxidant protection, stabilized water quality, reduced cortisol levels, suppressed pro-apoptotic gene expression (hsp70, hsp90, il-6, caspase 3, caspase 8, and bax), while upregulating the anti-apoptotic gene bcl-2. These alterations contributed to lower lactic acid accumulation and glycogen consumption, enhanced muscle shear force, reduced drip loss, and improved structural integrity of the gill, liver, and muscle tissues. The eugenol group effectively limited ammonia nitrogen accumulation, decreased glutathione peroxidase activity, and downregulated stress and apoptosis-related genes (bax, caspase 3, and caspase 9), resulting in reduced tissue damage. In contrast, the NaCl compound group accelerated water quality deterioration, increased TDS (total dissolved solids), lowered dissolved oxygen, and weakened stress resistance, leading to more severe tissue damage. Overall, microencapsulation or eugenol co-application were the most effective strategies for enhancing survival and maintaining muscle quality during transportation.",
"40891497": "ID: 40891497\nTitle: Autophagy and exosomes play different roles in the disposal of unwanted cellular materials.\nAbstract: Degradative autophagy supplies a source of nutrients and energy by digesting cytoplasmic components. Additionally, it eliminates toxic protein aggregates and defective organelles from cells. Exosomes are small vesicles that are released by cells into the extracellular environment and are also involved in maintenance of homeostasis by removing unwanted materials and intracellular pathogens. Nevertheless, it remains unclear how these two processes may differ or are alike in their roles in maintaining intracellular homeostasis. In this study, we found that secretory exosomes served as a quality control mechanism, maintaining intracellular RNA homeostasis by facilitating both the selective packaging of endogenous and exogenous RNA species. Conversely, autophagic degradation primarily functions to dispose of both endogenous and exogenous proteins, resulting in controlling intracellular proteostasis. The depletion of exosome secretion resulted in prolonged accumulation of exogenous RNA within the cells, whereas it had no significant effect on the accumulation of exogenous proteins. Viral infection not only induced the host autophagy response, but also impacted secretion of exosomes. Our data showed that secretory exosomes contributed to the clearing of increased intracellular microRNAs induced by enterovirus infection, thereby weakening viral replication. Furthermore, the secretory exosomes were essential for the disposal of viral RNA replicon rather than autophagic degradation, thereby facilitating host survival. Our results collectively revealed that both secretory exosome and autophagic degradation were crucial for maintaining cellular homeostasis, but that they operate through distinct mechanisms and dispose of different types of unwanted materials.",

Exploiting FDA-approved drugs to induce ferroptosis offers a novel approach that exploits cancer cells' vulnerabilities in iron metabolism and oxidative stress. Here, we identify artesunate, an antimalarial drug, as a potent inducer of ferroptosis in gastric cancer cells and reveal the transferrin receptor (TFRC) as a key mediator in this process. Notably, our study is the first to demonstrate an interaction between artesunate and TFRC through molecular docking and surface plasmon resonance (SPR) experiments, highlighting a novel mechanism by which artesunate stabilizes TFRC by inhibiting its lysosomal degradation. This stabilization is regulated via the heat shock protein HSPA9, another previously unreported interaction. Disrupting the TFRC-HSPA9 interaction facilitates iron accumulation and lipid peroxidation, hallmark features of ferroptosis, leading to significant cancer cell death. Additionally, in vivo studies confirm artesunate's anti-tumor efficacy, showing marked tumor growth inhibition and minimal systemic toxicity. These findings underscore the therapeutic relevance of targeting ferroptosis in cancer, particularly by leveraging TFRC's role in iron homeostasis. Furthermore, this study expands the understanding of post-translational regulation in ferroptosis, offering a new perspective on the role of artesunate in cancer therapy.",
"40947322": "ID: 40947322\nTitle: Heat shock protein 70 (Hsp70) as a target for advancing immunotherapy in solid tumors.\nAbstract: Heat shock protein 70 (Hsp70) is a highly conserved molecular chaperone that maintains protein homeostasis (proteostasis) under stress conditions. In cancer, Hsp70 is frequently overexpressed, where it contributes to hallmark features of malignancy by stabilizing oncogenic proteins, suppressing apoptosis, and promoting invasion and immune evasion. Beyond its intracellular functions, Hsp70 is aberrantly presented on the plasma membrane of a broad range of solid tumor cells and actively released into the extracellular space, either in soluble form or encapsulated within extracellular lipid microvesicles with biophysical characteristics of exosomes, supporting tumor microenvironment remodeling and immune modulation. The selective surface expression of Hsp70 on tumor cells, but not healthy tissues, defines it as a tumor-associated antigen (TAA) and an accessible target for immunotherapy. Leveraging this unique feature, several therapeutic approaches have been developed addressing membrane Hsp70 on tumor cells, including small molecule inhibitors, peptide-mediated activation of natural killer (NK) cells, monoclonal antibodies, fusion vaccines, and chimeric antigen receptor (CAR)-engineered immune cells. In parallel, extracellular Hsp70 in the blood is emerging as a promising liquid biomarker for patient stratification and treatment monitoring in cancer patients. This review outlines the context-dependent roles of Hsp70 in cancer and critically evaluates its translational potential as both a therapeutic target and diagnostic marker in solid tumors. We also discuss advances in detection technologies, findings from early-phase clinical trials, and persistent challenges such as off-target effects, tumor heterogeneity, and achieving effective and selective targeting.",

Heat shock protein 70 (Hsp70) and Hsp90 (Hsp90) are ATP-dependent chaperones essential for protein quality control, signaling, and stress adaptation. Their activities are controlled not only by co-chaperones, but also by dynamic post-translational modifications (PTMs). This review dissects phosphorylation, acetylation, methylation, ubiquitination, glycosylation, and other PTMs of Hsp70 and Hsp90 across systems. These PTMs regulate the ATPase activity, localization, and interactions of the molecular chaperones with major implications in health and disease. The term \"chaperone code\" describes the PTM landscape that fine-tunes chaperone function. This code governs client fate, drug sensitivity, and stress responses. Importantly, combinatorial PTMs introduce regulatory complexity and flexibility, especially in cancer, neurodegeneration, and inflammation. The crosstalk between various PTMs and feedback loops add new regulatory layers to chaperone function. Additionally, these PTMs impact the function of the clients that are central in regulating specific cellular processes or pathways, such as transcription, autophagy, metabolism, and immune regulation. These pathways are usually affected in different maladies, such cancer, neurodegenerative, infectious and chronic diseases. Unlocking the chaperone code is essential for directing chaperone activity toward therapeutic benefit. This can be achieved by targeting enzymes that write, erase, or read the chaperone code, thereby offering new therapeutic strategies.",

However, knowledge of PQC machinery-mediated handling of stress-induced misfolded proteins is still insufficient. We used the yeast kinase Ste11 to observe its fate upon heat stress or Hsp90 inhibition. We observed that while mild heat stress (37\u2009\u00b0C) primarily resulted in proteasomal degradation of Ste11, severe heat stress (42\u2009\u00b0C) resulted predominantly in aggregation. Ste11 aggregates sequestered with Hsp42 upon heat stress or Hsp90 inhibition. These aggregates associate with Hsp70 and Hsp104, the yeast disaggregase machinery. Notably, Ste11 aggregates disappear upon recovery from stress. This phenomenon is impaired in the absence of Hsp104 or Sse1, a co-chaperone recruited to the aggregates by Hsp70, suggesting the involvement of Hsp104, Hsp70 and Sse1 in aggregate mobilisation.",

"41031819": "ID: 41031819\nTitle: The E3 ubiquitin ligase STUB1 inhibits Senecavirus A replication by mediating VP1 ubiquitination and proteasomal degradation.\nAbstract: Senecavirus A (SVA), an emerging vesicular pathogen, poses a significant threat to the global pig industry. STIP1 homology and U-box-containing protein 1 (STUB1), a chaperone-dependent E3 ubiquitin ligase, plays a pivotal role in protein quality control by mediating target protein degradation. However, its precise role of STUB1 in regulating SVA replication remains undefined. In this study, we combined liquid chromatography-mass spectrometry, confocal imaging, and Western blotting to demonstrate that STUB1 interacts with the SVA VP1 protein and negatively regulates SVA replication. Mechanistically, STUB1 promotes the ubiquitination-dependent degradation of VP1 by specifically targeting lysine residues at positions 177 and 260 (K177 and K260). This degradation process is significantly enhanced by heat shock protein 70 (HSP70) and heat shock cognate protein 70 (HSC70), which strengthen the STUB1-VP1 interaction. Notably, the SVA 3C protease (3Cpro) counteracts this antiviral defense by enzymatically reducing STUB1 expression. In vivo studies using a mouse model showed that a VP1 mutant virus lacking STUB1-targeted ubiquitination sites replicates more efficiently than the wild-type strain, resulting in significantly higher viral loads across multiple tissues and more severe pulmonary pathology. Together, these findings reveal that STUB1 inhibits SVA replication through ubiquitination-dependent degradation of VP1, a process that is antagonized by viral 3C protease via suppression of STUB1 expression. Viruses have evolved diverse strategies to enhance their replication efficiency. Senecavirus A (SVA), an emerging porcine pathogen associated with vesicular disease outbreaks, has become increasingly prevalent in swine populations worldwide. As a chaperone-dependent E3 ubiquitin ligase, STUB1 plays a crucial role in maintaining cellular protein homeostasis. In this study, we elucidated the functional interplay between STUB1 and SVA replication. Our results demonstrate that STUB1 directly interacts with the viral protein VP1 and mediates its ubiquitination-dependent degradation through specific targeting of lysine residues at positions 177 and 260 (K177 and K260), thereby significantly inhibiting viral replication. However, SVA has evolved a countermeasure, whereby its 3C protease (3Cpro) downregulates STUB1 expression, effectively blocking VP1 degradation and subverting this host antiviral defense to promote viral propagation. These findings not only reveal novel host-virus interaction mechanisms but also provide valuable molecular targets for developing innovative strategies to control SVA infection.",

Despite this commonality, synucleinopathies display divergent disease phenotypes that have been attributed to disease-specific three-dimensional structures of \u03b1-synuclein fibrils, each with unique toxic gain-of-function profiles. The Hsc70 chaperone is remarkable in its ability to disassemble pre-existing amyloid fibrils of different proteins in an ATP and co-chaperone-dependent manner. We find, however, using six well-defined conformational polymorphs of \u03b1-synuclein fibrils, that the activity of the Hsc70 disaggregase machinery is sensitive to differences in the amyloid conformation, confirming that fibril polymorphism directly affects interactions with the proteostasis network. Amyloid conformation influences not only how efficiently fibrils are cleared by the Hsc70 machinery but also the balance between depolymerization and fragmentation during disaggregation. We further show that, in vitro, the active processing of fibrils by the Hsc70 machinery inadvertently produces seeding competent species that further promote protein aggregation. Amyloid conformation thus is an important feature that can tilt the balance between beneficial or detrimental protein quality control activities in a disease-context.",

Therefore, it is of paramount importance to unravel strategies and mechanisms through which this goal can be achieved. Valproic acid (VPA) downregulates the expression of MUT TP53 in several tumor cells, although the mechanisms involved remain to be explored. Here, we demonstrate for the first time that acetylation induced by VPA promotes the lysosomal degradation of MUT TP53 and that it occurs preferentially through chaperone-assisted selective autophagy (CASA). Indeed, acetylation of MUT TP53 increases its interaction with STUB1 (STIP1\u00a0homology and U-box containing protein 1), HSPB8 (heat shock protein family B (small) member 8) and HSPA8 (heat shock protein family A (Hsp70) member 8) and the latter, itself acetylated by VPA, binds to BAG3 (BAG cochaperone 3), facilitating the recruitment of MUT TP53 into the CASA pathway. These findings elucidate the mechanisms through which acetylation leads to the selective lysosomal clearance of MUT TP53, highlighting a potential therapeutic vulnerability of aggressive tumors expressing this oncoprotein.Abbreviations: ACTB: actin beta; ATG5: autophagy related 5; BAF: bafilomycin A1; CMA: chaperone-mediated autophagy; GAPDH: glyceraldehyde-3-phosphate dehydrogenase; HSPA8: heat shock protein family A (Hsp70) member 8; LAMP2A: lysosomal associated membrane protein 2A; MAP1LC3B: microtubule associated protein 1 light chain 3 beta; SQSTM1: sequestosome 1; TP53: tumor protein p53.",

Hsp70s achieve their functions through 'selective promiscuity', interacting with a wide range of substrate proteins while minimizing undesired interactions. J-domain proteins (JDPs) and nucleotide exchange factors (NEFs) are key to substrate recognition, remodelling and release from chaperone complexes. JDPs either target Hsp70s to specific subcellular sites where substrates reside (recruiters) or bind substrates directly by using highly specific (specialists) or multiple, versatile (generalists) binding sites. Through diverse substrate-binding modes and regulatory mechanisms, the 50 human JDPs confer remarkable client specificity to Hsp70s, a function that is comparable to that achieved by close to 600 E3 ubiquitin ligases in targeting proteins for degradation. Moreover, JDPs, together with NEFs, dictate the fate of Hsp70 clients by directing them to distinct protein quality control pathways, resulting in their folding or degradation.

This study focuses on the role and regulatory mechanisms of super enhancer long non-coding RNA (SE-lncRNA) in TNBC. Through in-depth analysis of TCGA database, we revealed the specific expression pattern of SE-lncRNA in TNBC, and found that downregulation of RP11-54O7.17 was significantly correlated with poor prognosis of TNBC patients, which was experimentally verified. Both in vitro and in vivo results confirmed that RP11-54O7.17 overexpression effectively suppressed the proliferation and metastasis of TNBC. Further exploration showed that RP11-54O7.17 directly interacted with the S100A4 protein through its conserved L2b-type repeat structural fragment, promoted S100A4 binding to HSP70, targeting S100A4 degradation via the autophagy-lysosome pathway, which in turn blocked the activation of S100A4-STAT3 signaling axis.

Here, we show that both pathways are disrupted in AD model mice, preceding \u03b2-amyloid accumulation and driving disease progression. However, therapeutic autophagy modulation is severely restricted by the blood-brain barrier (BBB). To overcome this, we developed Microglia-Liposome Fusion Extrusion (MiLi-FE), a method to engineer microglia-derived nanovesicles (AR@ENV) for the codelivery of AR7 (a CMA inducer) and rapamycin (a macroautophagy inducer). Leveraging its microglial membrane origin, AR@ENV effectively crosses the BBB and targets inflammatory sites in the AD brain, where it is internalized by neurons. Once inside, they synchronously activate both autophagy pathways: AR7 antagonizes retinoic acid receptor alpha (RAR\u03b1) to enhance CMA, while rapamycin inhibits mTOR to promote macroautophagy. This coordinated activation enhances clearance of \u03b2-amyloid and other toxic aggregates, restores proteostasis, and provides robust neuroprotection. Furthermore, the strategy ameliorates neuroinflammation and significantly rescues cognitive deficits in two distinct AD mouse models.

MSC-PLGA-NPs demonstrated 2.3-fold higher BBB penetration efficiency compared to PLGA alone. In a chloroquine(CQ)-induced lysosomal injury model and mice model, they effectively restored lysosomal pH, enhanced autophagy (reducing LC3-II/I ratio by 0.4-fold and p62 expression by 52%), cleared amyloid precursor protein (APP) and phosphorylated tau (p-tau) proteins, and inhibited IL-6 and TNF-\u03b1 without hepatorenal toxicity.

Their increased formation under certain cellular circumstances has gained growing interest due to their association with serious human diseases, such as neurodegenerative disorders and cancer. The biological functions of paraspeckles still appear obscure, but increasing evidence suggests that they contribute to regulation of gene expression by recruiting specific proteins and RNA molecules. Here, we have characterized and compared two stress-enriched interactomes of the essential paraspeckle protein NONO in both wild-type and paraspeckle-deficient NEAT1 knockout cells. We identified Hsp70 as part of stress-enriched NONO complexes in wild-type but not in NEAT1-depleted cells. We show that proteotoxic stress-induced paraspeckle formation and NEAT1 expression are strictly dependent on Hsp70 chaperone activity. Our data demonstrate that both NONO and Hsp70 transiently translocate to the nucleolus during heat shock and that paraspeckle formation during recovery follows Hsp70-dependent relocation of NONO from the nucleolus to the nucleoplasm. Taken together, we demonstrate an important role of Hsp70 in paraspeckle assembly and identify a possible link between the nuclear protein quality control system and paraspeckles.",

Two key quality-control mechanisms -the ubiquitin proteasome system (UPS) and the release of mitochondria-derived vesicles- help maintain mitochondrial proteostasis, but whether these processes interact remains unclear. Here, we show that CRL5Ozz and its substrate, Alix, localize to mitochondria and together regulate the levels and distribution of the mitochondrial solute carrier Slc25A4, which is essential for ATP production. In Ozz-/- or Alix-/- mice, skeletal muscle mitochondria exhibit similar morphological abnormalities, including swelling and dysmorphism, along with partially overlapping metabolomic alterations. We demonstrate that CRL5Ozz ubiquitinates Slc25A4, targeting it for proteasomal degradation, while Alix facilitates Slc25A4 loading into exosomes for lysosomal degradation. Loss of Ozz or Alix in vivo disrupts the steady-state levels of Slc25A4, impairing mitochondrial metabolism and triggering a switch in muscle fiber composition from oxidative, mitochondria-rich slow to glycolytic fast fibers.",

In this respect, this article presents a concise overview on: the clinical relevance of the most important clocks and biomarkers used in skin anti-ageing strategy evaluation, the fundamentals, the main illustrating examples preclinically and clinically tested, the critical insights on knowledge gaps and future research perspectives concerning the most relevant skin anti-ageing and rejuvenation strategies based on novel epigenomic and genomic acquisitions. Thus the review dedicates distinct sections to: senolytics and senomorphics targeting senescent skin cells and their senescent-associated phenotype; strategies targeting genomic instability and telomere attrition by stimulation of the deoxyribonucleic acid (DNA) repair enzymes and proteins essential for telomeres' recovery and stability; regenerative medicine based on mesenchymal stem cells or cell-free products in order to restore skin-resided stem cells; genetically and chemically induced skin epigenetic partial reprogramming by using transcription factors or epigenetic small molecule agents, respectively; small molecule modulators of DNA methylases, histone deacetylases, telomerases, DNA repair enzymes or of sirtuins; modulators of micro ribonucleic acid (miRNA) and long-non-coding ribonucleic acid (HOTAIR's modulators) assisted or not by CRISPR-gene editing technology (CRISPR: Clustered Regularly Interspaced Short Palindromic Repeats); modulators of the most relevant altered nutrient-sensing pathways in skin ageing; as well as antioxidants and nanozymes to address mitochondrial dysfunctions and oxidative stress. In addition, some approaches targeting skin inflammageing, altered skin proteostasis, (macro)autophagy and intercellular connections, or skin microbiome, are very briefly discussed. The review also offers a comparative analysis among the newer genomic/epigenomic-based skin anti-ageing strategies vs. classical skin rejuvenation treatments from various perspectives: efficacy, safety, mechanism of action, evidence level in preclinical and clinical data and regulatory status, price range, current limitations. In these regards, a concise overview on senolytic/senomorphic agents, topical nutrigenomic pathways' modulators and DNA repair enzymes, epigenetic small molecules agents, microRNAs and HOTAIRS's modulators, is illustrated in comparison to classical approaches such as tretinoin and peptide-based cosmeceuticals, topical serum with growth factors, intense pulsed light, laser and microneedling combinations, chemical peels, botulinum toxin injections, dermal fillers. Finally, the review emphasizes the future research directions in order to accelerate the clinical translation of the (epi)genomic-advanced knowledge towards personalization of the skin anti-ageing strategies by integration of individual genomic and epigenomic profiles to customize/tailor skin rejuvenation therapies.",
"41497405": "ID: 41497405\nTitle: Hydrophobic tagging: A promising paradigm for targeted protein degradation.\nAbstract: Targeted protein degradation (TPD) has emerged as a groundbreaking therapeutic strategy, overcoming the limitations of traditional occupancy-driven pharmacology. Among TPD strategies, hydrophobic tag (HyT) technology exemplifies this paradigm shift by hijacking cellular protein quality control mechanisms for precise protein elimination. Structurally, HyT molecules integrate a target-specific ligand with a hydrophobic domain that emulates misfolded protein surfaces, facilitating selective recruitment of chaperone systems (e.g., heat shock protein 70, HSP70) and ubiquitin-proteasome system (UPS) activation, circumventing the E3 ligase dependency inherent to proteolysis-targeting chimera (PROTAC) systems. This innovative strategy offers distinct therapeutic benefits, including enhanced tissue-specific accumulation and the capacity to overcome resistance mechanisms. This review highlights the important advances in this rapidly growing field and critical limitations encountered in developing HyT degraders by analyzing the current status and representative examples of HyTs in degrading diverse pathogenic proteins, including oncogenic drivers (e.g., signal transducer and activator of transcription 3, STAT3), neurodegenerative aggregates (tau, \u03b1-synuclein), and viral envelope proteins. The critical developments, including the rational design of hydrophobic motifs and possible mechanistic insight into the degradation process of HyTs, have also been discussed.",
"41596312": "ID: 41596312\nTitle: Investigating the Potential Role of Capsaicin in Facilitating the Spread of Coxsackievirus B3 via Extracellular Vesicles.\nAbstract: Coxsackievirus B3 (CVB3) is a picornavirus that causes systemic inflammatory diseases including myocarditis, pericarditis, pancreatitis, and meningoencephalitis. We have previously reported that CVB3 induces mitochondrial fission and mitophagy while inhibiting lysosomal degradation by blocking autophagosome-lysosome fusion. This promotes the release of virus-laden mitophagosomes from host cells as infectious extracellular vesicles (EVs), enabling non-lytic viral egress. Transient receptor potential vanilloid 1 (TRPV1), a heat and capsaicin-sensitive cation channel, regulates mitochondrial dynamics by inducing mitochondrial membrane depolarization and fission. In this study, we found that TRPV1 activation by capsaicin dramatically enhances CVB3 egress from host cells via EVs. Released EVs revealed increased levels of viral capsid protein VP1, mitochondrial protein TOM70, and fission protein phospho-DRP1. Moreover, these EVs were enriched in heat shock protein HSP70, suggesting its role in facilitating infectious EV release from cells. Furthermore, TRPV1 inhibition with capsazepine and SB-366791 significantly reduced viral infection in vitro. Our in vivo studies also found that SB-366791 significantly mitigates pancreatic damage and reduces viral titers in a mouse model of CVB3 pancreatitis. Given the lack of understanding regarding factors that contribute to diverse clinical manifestations of CVB3, our study highlights capsaicin and TRPV1 as potential exacerbating factors that facilitate CVB3 dissemination via mitophagy-derived EVs.",

Following the central nervous system (CNS) injury, BIS expression is markedly upregulated in reactive astrocytes, suggesting a regulatory role of reactive astrogliosis. To investigate this, we generated astrocyte-specific BIS knockout (BIS-aKO) mice for the first time. While BIS-aKO mice exhibited normal growth and survival, the injury-induced upregulation of BIS expression was abolished in reactive astrocytes following excitotoxic injury. Using a photothrombotic stroke model, we found that astrocytic BIS deficiency resulted in significantly increased GFAP expression in scar-forming astrocytes at the infarct border and altered morphology in the peri-infarct region. Furthermore, we observed increased infiltration of amoeboid Iba1-positive cells in the astroglial scar, indicating enhanced neuroinflammation. Correlative light-and electron-microscopy following both stroke and stab wound injury revealed BIS-aKO astrocytes exhibited a greater density of intermediate filament filling in their soma and processes, along with relatively fewer cytoplasmic organelles, such as mitochondria. Collectively, these findings highlight a previously unrecognized role of BIS in modulating reactive gliosis during brain injury and our model provides a valuable tool for investigating the astrocyte-specific functions of BIS in CNS pathophysiology.",
"41609899": "ID: 41609899\nTitle: Stress-specific expression of HSPA and DNAJ chaperones regulated by NRF2/HSF1 in neurodegenerative conditions.\nAbstract: The cellular protein quality control and protein homeostasis is maintained by molecular chaperones that are upregulated in response to various environmental, chemical, thermal and genetic stress factors. Altered protein homeostasis owing to stress conditions lead to the accumulation of misfolded and aggregated protein conformers, a hallmark feature of several neurodegenerative and metabolic diseases. However, the effect of different stress conditions on the expression of molecular chaperones remains poorly understood. In the present study, comparative expression profile of the HSPA and DNAJ chaperone family has been analysed under oxidative stress induced by rotenone, proteotoxic stress induced by \u03b1-synuclein seeds, proteasome inhibitor and heat stress conditions. A dynamic and stress-selective expression of molecular chaperones was observed at both the gene and protein levels, where HSPA1 (HSP70), HSPA5 and DNAJB1 proteins were upregulated across all stress conditions, while HSPA8 (HSC70), HSPH1 (HSP110), DNAJB6 and DNAJB8 proteins exhibited stress-dependent unique expression patterns. The selective expression of molecular chaperones regulated through the NRF2/HSF1 axis suggests the involvement of the KEAP1/NRF2/ARE pathway in coordinating stress-dependent chaperone expression and ensuring proteome integrity. This comparative stress-specific expression profiling enables targeting of molecular chaperones to mitigate protein misfolding and aggregation, facilitating therapeutic interventions in neurodegenerative diseases.",
"41611432": "ID: 41611432\nTitle: ROS-responsive oligochitosan-derived nanovesicles with synergistic oxidative stress and autophagy inhibition for potent tumor therapy.\nAbstract: Oxidative stress-mediated tumor therapy leverages reactive oxygen species (ROS) for cancer treatment, but protective autophagy, a major survival pathway for tumor cells, causes therapy resistance. Herein, a self-amplifying ROS-responsive nanovesicle system (CQ/Cu@CT) is designed to enhance oxidative stress while blocking autophagy. Firstly, amphiphilic oligochitosan derivative COS-PEG2KTA-UB is synthesized, where ROS-responsive thioketal acetal (TA) is introduced in form of cinnamaldehyde (CA) prodrug. This polymer self-assembles into nanovesicles, integrating chloroquine (CQ) and supplemental TA to immobilize Cu2+ via carboxylic coordination. Intracellular ROS triggers nanovesicle dissociation to release CA, Cu2+, and CQ. CA induces mitochondrial dysfunction and ROS burst, while Cu2+ depletes glutathione and generates Cu+ for Fenton-like reactions to produce hydroxyl radicals. Meanwhile, due to the inhibition effect of CQ on protective autophagy, CQ/Cu@CT produces significantly high ROS level. The amplified ROS not only aggravates oxidative stress but also accelerates drug release from nanovesicles, which facilitates the drug action against tumors. CQ/Cu@CT also induces immunogenic cell death (ICD) to stimulate dendritic cell maturation and enhance cytotoxic T lymphocyte infiltration. Consequently, CQ/Cu@CT inhibits tumor growth by 67.8\u00a0% in a subcutaneous 4\u00a0T1 tumor model. This study provides a potent strategy to enhance oxidative stress-based cancer therapy.",

The meeting highlighted the continued evolution of the heat shock response from a canonical transcriptional program to a complex, multi-layered network integrating transcriptional condensates, posttranslational regulation of chaperones, spatial organization, and system-level stress adaptation. Scientific sessions showcased advances in stress-induced transcription and genome control, the expanding Hsp90/Hsp70 \"chaperone code,\" proteostasis and protein quality control, mitochondrial chaperones and metabolic regulation, cancer-immune interfaces, host-pathogen interactions, and the roles of chaperones in aging and neurodegenerative disease. Particular emphasis was placed on emerging therapeutic and diagnostic strategies, including isoform-specific chaperone inhibitors, co-chaperone targeting, theranostic approaches, and clinical-stage candidates. Systems-level analyses of stress resilience, extracellular chaperone signaling, and organismal adaptation further underscored the breadth of stress biology across scales. The symposium also honored the legacy of Dr\u00a0Len Neckers, whose pioneering contributions to Hsp90 biology shaped the field, and recognized outstanding scientific achievements through CSSI awards and fellowships. Collectively, the work presented reflects a field that continues to deepen mechanistic understanding while advancing toward precision-based therapeutic and diagnostic applications.

"41653632": "ID: 41653632\nTitle: Growth performance and antioxidant response of broiler chicken fed oxidized lipids with or without phytogenic feed additives.\nAbstract: The aim of this study was to test the in vivo antioxidant capacity in broilers of two phytogenic additives, one derived from olive pomace (OE) and an encapsulated product based on Capsicum sp., black pepper, and ginger (SPICY), in a challenge using oxidized lipids in the feed. A total of 720 one-day-old male Cobb 500 were allocated to 72 pens (8 treatments, 9 replicates, 10 birds/replicate). The treatments were arranged in a 2 \u00d7 2 \u00d7 2 factorial, the factors being: fat source (4% soybean oil or 4% peroxidized soybean oil); SPICY (0 or 250 ppm); and OE (0 or 3077 ppm). From 1 to 21 days (global period) no significant differences were observed on performance. Broilers fed peroxidized oil showed higher plasma ferric reducing antioxidant power (FRAP; P < 0.05) values and higher catalase (CAT) activity compared to those fed fresh oil except in those birds fed the OE which remained constant with both oil sources (P < 0.05 for the interaction). Broilers fed OE showed a significant lower CAT gene expression in the liver (P < 0.05). Moreover, the heat shock protein 70 (HSP70) gene expression was lower in birds fed fresh oil and OE compared to those fed fresh oil without OE but higher in birds fed peroxidized oil and OE compared to those fed peroxidized oil without OE (P < 0.05 for the interaction). By contrast, broilers fed SPICY upregulated CAT (P < 0.05) and downregulated HSP70 (P < 0.05) gene expression in the liver compared to those not supplemented with SPICY. In conclusion, feeding broilers with peroxidized soybean oil from 1 to 21 days of age did not affect the productive parameters. However, the presence of lipid peroxidation products in the feed triggered both non-enzymatic and enzymatic antioxidant responses to maintain the oxidant/antioxidant balance. In the case of birds fed the OE, the enzymatic antioxidant response was more attenuated, indicating a better control of oxidative stress, likely mediated by HSP70.",

In this study, we used human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) to characterize the transcriptional impact of CFZ and to evaluate whether atorvastatin could prevent these deleterious transcriptional changes. hiPSC-CMs were treated with 1 \u00b5M CFZ, CFZ + atorvastatin, atorvastatin, or vehicle control, followed by RNA sequencing, differential expression analyses, and pathway analyses. Transcriptomic profiling revealed a marked upregulation of genes in multiple proteasome subunits, including ATPase components (PSMC1, PSMC4, PSMC5, PSMC6) and non-ATPase regulatory subunits (PSMD1, PSMD2, PSMD12), suggesting a strong compensatory activation of proteostasis and protein quality-control pathways in response to CFZ exposure. In addition, several of the most significantly altered genes were those implicated in cardiomyopathy and heart failure, such as BAG3 and FLNC, and many heat-shock proteins, indicating the activation of cardiac stress-response pathways relevant to CFZ-associated cardiotoxicity. Atorvastatin co-treatment partially reversed a subset of CFZ-induced transcriptional changes, particularly within cholesterol biosynthesis and lipid-regulatory pathways (e.g., ACAT2 and ACTA1) but did not restore the CFZ-mediated downregulation of sarcomeric genes. Together, these findings define a multifactorial signature of deleterious CFZ-induced transcriptional changes and suggest that atorvastatin may provide partial metabolic, but not structural, cardio protection.",

MFN2 (mitofusin 2) mediates mitochondrial fusion and ensures adaptations in response to metabolic changes and stresses. Besides this canonical role, MFN2 serves as a communication hub with other organelles. It tethers mitochondria to the endoplasmic reticulum (ER), lipid droplets, and peroxisomes, regulating calcium buffering, apoptosis, lipid biosynthesis, and lipolysis. Dysfunctional MFN2 causes the hereditary neuropathy Charcot-Marie-Tooth type 2A (CMT2A) and is linked to several metabolic diseases. In a recent publication, we described another fusion-independent role of MFN2 in proteostasis and mitophagy. MFN2 binds the chaperone HSPA8/HSC70 (heat shock protein family A [Hsp70] member 8) and the proteasome, a key function in maintaining mitochondrial and cellular protein quality control, which appears to be lost in the context of CMT2A-associated MFN2 variants.",
"41763428": "ID: 41763428\nTitle: Aedes aegypti Hsp70 has enhanced ATPase and protein protection under oxidative stress.\nAbstract: Aedes aegypti mosquitoes are responsible for transmitting several viral diseases in humans, including Dengue, Zika, Yellow Fever, and Chikungunya. Despite significant efforts to control the mosquito vector and the viruses, the issue has intensified. This is mainly due to the mosquito's successful adaptation to urban environments and its expanding geographic range, driven by rising global temperatures. To effectively combat vector-borne diseases, we need a comprehensive understanding of mosquito physiology and cellular regulatory mechanisms, as these could reveal new molecular targets for intervention. A major cellular threat is environmental stress, which can cause protein misfolding and aggregation, ultimately leading to cell death. To counteract this, cells utilize their Protein Quality Control (PQC) system to maintain proteostasis. A central component of this system is the Hsp70 chaperone family, which is crucial for nascent protein folding, translocation across membranes, refolding of aggregated proteins, targeting proteins for degradation, and providing general stress protection. In this context, we identified, cloned, expressed, and characterized a cytosolic Hsp70 homolog from Aedes aegypti, which we named AaHsp70. The recombinant AaHsp70 protein was obtained in a pure and folded form, functioning as a monomer in solution and exhibiting hallmark features of the Hsp70 family, including ATPase activity and chaperone function. Notably, its ATPase activity was 2.5 to 3.3 times higher than that of human Hsp70s and increased by 90% under oxidative conditions. Furthermore, AaHsp70 successfully protected several proteins from aggregation under redox stress in Aedes larval cell extracts. Among the protected proteins was actin, a crucial cytoskeletal and contractile protein involved in both larval and adult muscle function in insects. Overall, our findings demonstrate that AaHsp70 plays a vital role in maintaining protein homeostasis under stress in mosquito cells. This chaperone may represent a promising molecular target for developing novel strategies to mitigate the spread of Aedes aegypti and the diseases it transmits.",

Plant-derived nanovesicles have emerged as natural, biocompatible nanomedicines with potential applications in cancer therapy. Here, we systematically screened nanovesicles from ten medicinal plants and identified Panax notoginseng-derived nanovesicles (PnNVs) as the most potent inhibitors of OSCC. PnNVs exhibited favorable safety profiles and intrinsic tumor-homing ability, selectively accumulating in orthotopic tongue tumors. In vivo, they markedly suppressed primary tumor growth and lymphatic metastasis. Mechanistically, PnNVs disrupted redox homeostasis by inhibiting the p38-MAPK/NRF2 signaling pathway, thereby inducing ferroptosis, autophagy, and PANoptosis. In addition, PnNVs impaired cancer cell migration by modulating chemokine-associated signaling pathways critical for tumor dissemination. Multi-omic analyses further revealed synergistic contributions of RNA cargos and metabolite components to their multi-target anticancer efficacy. Collectively, our findings establish PnNVs as a natural, multifunctional therapeutic candidate with dual anti-proliferative and anti-metastatic activity, providing a promising preclinical strategy for OSCC treatment.",
"41833626": "ID: 41833626\nTitle: Autophagy-exosome crosstalk in neurodegeneration: Mechanisms and therapeutic opportunities.\nAbstract: Neurodegenerative diseases (NDs), including Alzheimer's, Parkinson's, Huntington's, amyotrophic lateral sclerosis, and multiple sclerosis, share a common pathogenic signature: disrupted proteostasis driven by impaired autophagy and maladaptive exosome dynamics. Under normal conditions, autophagy maintains neuronal homeostasis by clearing misfolded proteins and damaged organelles, while exosomes mediate neuroglial communication. When autophagic flux is impaired or lysosomal function is compromised, intracellular cargo handling can shift toward secretion and undegraded cargo may be redirected into exosomes/EVs, which disseminate pathogenic proteins such as amyloid-\u03b2, tau, \u03b1-synuclein, and TDP-43, a phenomenon reported in several experimental models and proposed to contribute to intercellular spread of pathology. This dual dysregulation amplifies neuroinflammation, demyelination, and progressive neuronal loss. Pharmacological strategies aimed at restoring the autophagy-exosome axis are gaining traction. Agents such as rapamycin and resveratrol enhance autophagic flux, whereas engineered or stem-cell-derived exosomes delivering siRNAs, neurotrophic factors, or anti-inflammatory microRNAs show promise in preclinical neuroprotection and immune modulation. However, translational barriers remain, including safety, biodistribution, dosing, and standardization. Emerging artificial intelligence (AI) and machine learning (ML) frameworks can accelerate translation by integrating multi-omics and exosomal biomarker datasets for early diagnosis, patient stratification, and therapy optimization. Deep learning and generative modeling may further enable rational drug design to fine-tune autophagy and engineer targeted exosome delivery to the brain. Collectively, these advances position the autophagy-exosome axis as an integrative framework linking intracellular clearance with intercellular signaling, with emerging diagnostic and therapeutic implications for neurodegenerative disorders.",
"41833837": "ID: 41833837\nTitle: Crystal structures reveal phosphorylation-dependent disruption of the heat shock protein 70-CHIP interface: A compensatory G132N variant restores binding affinity.\nAbstract: Heat shock protein 70 (HSP70) and its E3 ligase co-chaperone CHIP (STUB1) form a critical quality-control complex that directs client proteins toward folding or degradation. Phosphorylation of HSP70 at a conserved threonine in the C-terminal tail influences the fate of clients during cellular stress, yet the structural basis for this regulation remains unclear. Here, we present crystal structures of the CHIP tetratricopeptide repeat (TPR) domain bound to unphosphorylated and phosphorylated HSP70 C-terminal peptides at 1.6-1.9\u00a0\u00c5 resolution. Phosphate occupancy at Thr636 (HSPA1A numbering) causes steric clashes and electrostatic repulsion within the TPR-binding groove, decreasing affinity by more than 10-fold, as shown by biolayer interferometry and fluorescence polarization. Molecular dynamics simulations confirm destabilization of key hydrogen bonds. A structure-guided G132N substitution in CHIP introduces new hydrogen bonds to the phosphate group, restoring affinity for phosphorylated peptides in isolated TPR domains without losing native ubiquitination activity. However, in full-length CHIP, interface modifications do not restore phosphorylation-impaired stable binding but yield only partial recovery of transient interactions in cells, indicating additional context-dependent constraints on HSP70-CHIP regulation. These findings reveal the atomic mechanism by which phosphorylation impairs HSP70-CHIP interaction during stress and demonstrate that targeted interface engineering can compensate for post-translational changes in isolated domains. Overall, the results explain how cells switch chaperone-mediated triage pathways and offer a framework for understanding how proteostasis becomes dysregulated in neurodegenerative diseases and cancer.",

Herein, a small-molecule, Hsp70-based targeted protein degradation platform, termed Hsp70TAC, is described that enables tumor-selective degradation of both intracellular and extracellular proteins through distinct cellular pathways. By conjugating protein-of-interest (POI) ligands to Hsp70 inhibitors, Hsp70TACs exploits the chaperone functions of Hsp70 to enable protein degradation through both the ubiquitin-proteasome system and the endocytosis-lysosome pathway. As a proof of concept, Hsp70TACs induced efficient degradation of intracellular Bromodomain Protein 4 (BRD4) via the ubiquitin-proteasome system (DC50 = 0.67 \u03bcM) and membrane-bound Programmed Death Ligand 1 (PD-L1) via caveolin-mediated endocytosis-lysosomal processing (DC50 = 0.84 \u03bcM).

Here, we present a vaccine strategy based on cold atmospheric plasma (CAP)-engineered tumor cell-derived immune reprogramming nanovesicles (CAPTURE) that integrates spatiotemporal sequential immunization to potentiate antitumor immunity. CAPTURE is engineered from tumor cells pretreated with CAP, which up-regulates major histocompatibility complex class I expression via p62-mediated autophagy to promote full-spectrum epitope antigen presentation, and surface-functionalized anti-CD28 (\u03b1CD28) on CAPTURE provides costimulatory signals to directly activate T cells through \u03b1CD28-CD28, bypassing B7-CTLA-4-mediated T cell inhibition. Under spatiotemporal sequential immunity, CAPTURE exhibits homologous tumor targeting and lymph node accumulation, enhancing antigen presentation for CD8+ T cell activation and tumor immunogenic remodeling. In mouse models, CAPTURE achieved near-complete tumor suppression, driven by amplified cytotoxic T cell responses, increased T cell clonal diversity, and CXCR3-mediated tumor infiltration. This study presents a universal biomimetic nanovaccine strategy that can reshape both T cells' immunity and tumor cells' immunogenicity, induce broad-spectrum immune responses to overcome immune evasion, and offer unique insights and innovative technologies for precision cancer immunotherapy.",

In this study, we have developed Autophagy-Targeting Chimera-T-cell Engager (AUTACE), a bifunctional nanoplatform composed of T-cell receptor-engineered T (TCR-T) cell-derived nanovesicles that display anti-CD3 antibodies and encapsulate perfluoropentane (PFP) together with KPY, an autophagy-targeting degrader active against mutant KRAS, for the treatment of KRAS/TP53 co-mutant tumors. AUTACE targets tumors via TP53-specific TCRs, elicits antitumor CD8+ T-cell responses through surface anti-CD3 antibodies, and employs low-intensity focused ultrasound (LIFU) to trigger controlled release of KPY to degrade mutant KRAS. This achieved targeted tumor elimination. The therapeutic efficacy of AUTACE was validated in mice bearing PANC-1 and MIA PaCa-2 tumors. A comprehensive assessment of the post-treatment tumor microenvironment revealed that KRAS degradation increased tumor-derived CCL5 levels, thereby promoting CD8+ T-cell recruitment and amplifying antitumor responses.

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 define a previously unrecognized role for the budding yeast JDP Caj1 in modulating nucleocytoplasmic protein quality control. We show that elevated Caj1 levels broadly disrupt proteostasis, stabilizing diverse misfolded substrates by impairing their degradation and triggering the accumulation of ubiquitinated proteins, along with constitutive activation of the heat shock response (HSR). Caj1-induced defects were associated with the accumulation of ubiquitinated proteins. They were genetically suppressed by loss of the E3 ubiquitin ligases and enhanced by loss of deubiquitinating enzymes, revealing functional coupling between Caj1 activity and ubiquitin-mediated protein turnover. Co-overexpression of the major nucleocytoplasmic JDPs Ydj1 and Sis1 suppressed Caj1 toxicity, with Sis1 acting through a J-domain-dependent, Hsp104-independent mechanism. Our findings uncover a dosage-sensitive regulatory interplay among JDPs and demonstrate that relative JDP abundance, rather than absolute levels, is a critical determinant of proteostasis capacity, revealing a previously unrecognized functional network linking Caj1, Sis1, and Ydj1 in shaping cellular protein quality control.",

Infection by the Flaviviridae family often leads to severe acute or chronic illnesses, including hemorrhagic systemic diseases caused by dengue virus (DENV) and yellow fever virus, neurological complications associated with West Nile virus and Zika virus (ZIKV) infection, as well as liver damage and hepatocellular carcinoma resulting from hepatitis C virus (HCV) infection. Accumulating evidence indicates that a hallmark of Flaviviridae infection is to hijack calcium (Ca2+) signaling of the host cells, consequently facilitating viral entry, RNA replication, viral assembly, and release. Transient receptor potential (TRP) channels, a superfamily of nonselective cation channels, are central regulators of intracellular Ca2+ homeostasis. Recent studies reveal that TRP channels are closely involved in Flaviviridae infection. This comprehensive review synthesizes current findings on the role of TRP channels (e.g. TRPC, TRPV, TRPA, TRPM, and TRPML) in the pathogenesis of Flaviviridae viruses such as DENV, ZIKV, HCV, and Japanese encephalitis virus. Moreover, this review summarizes virus-TRP channel interaction mechanisms and discusses the potential of targeting TRP channels for host-directed antiviral therapies. This review aims to establish a conceptual framework for understanding TRP channel biology in Flaviviridae infection and to guide future research on antiviral strategies. Future directions should highlight the potential utility of TRP channel research for advancing anti-Flaviviridae therapies and clarifying their underlying mechanisms.",

Genetic studies, including genome-wide association studies, have identified variants in BAG3, a key regulator of protein quality control (PQC), as contributors to both familial and sporadic forms of DCM. Impaired PQC and the accumulation of misfolded proteins (proteinopathy) have emerged as potential pathogenic mechanisms. Here, we investigated the molecular consequences of a recently identified BAG3 missense variant (V468\u202fM) associated with familial DCM. To assess the in vivo effects of the variant, human BAG3V468M was ectopically expressed in wild-type zebrafish embryos. Overexpression of BAG3V468M resulted in a DCM-like phenotype characterized by ventricular dilation, reduced heart rate, and impaired contractility. Transmission electron microscopy revealed marked disruption of myocardial ultrastructure and sarcomeric organization. To explore the impact on proteostasis, markers of autophagy (LC3-I/II and p62) were analyzed and showed no significant differences between BAG3V468M and control embryos under basal conditions. In contrast, analysis of the ubiquitin-proteasome system demonstrated a significant accumulation of ubiquitinated proteins in BAG3V468M-expressing embryos, suggesting impaired proteasomal protein clearance or increased proteotoxic stress. Expression of BAG3V468M induces a DCM-like phenotype in vivo associated with disrupted myocardial architecture and altered proteostasis. While canonical autophagy markers remain unchanged, the accumulation of ubiquitinated proteins points toward a disturbance in ubiquitin-mediated protein turnover. These findings implicate mutation-specific alterations in proteostasis as a potential mechanism contributing to BAG3-associated cardiomyopathy.",

Recent research has significantly expanded our understanding of these molecular chaperones, revealing functions that extend beyond their classical roles in proteostasis. In this review, we integrate these emerging insights with foundational knowledge by outlining the biology of HSP70s, with particular emphasis on recent discoveries, such as new data on the substrate specificity and molecular dynamics of HSP70-client interactions. In addition, increasing evidence highlights their noncanonical anti-inflammatory properties, as well as other nonimmune functions, including the promotion of adipose tissue browning and the enhancement of angiogenesis through extracellular HSP70 activity. Finally, although HSP70s have long been known to regulate mRNA degradation in a transcript-specific manner, new findings demonstrate their ability to bind double-stranded RNA, further broadening their functional repertoire.",
"42112758": "ID: 42112758\nTitle: Integrated clinical and computational data-based repurposing of econazole as a novel autophagic activator in ULK1-related Parkinson disease.\nAbstract: Parkinson disease (PD), the second most common neurodegenerative disorder, is pathologically linked to dysregulated autophagy, a conserved lysosomal degradation pathway. Current conventional PD therapies are often limited by significant side effects, underscoring the demand for alternative treatment strategies. Drug repurposing of FDA-approved compounds represents a promising approach to address this unmet clinical need. Here, by integrating clinical data analysis, we identified an association between autophagy impairment and specific PD patient subtypes, suggesting that ULK1-dependent autophagy activation may offer therapeutic benefit. Through systematic screening for autophagy induction and neuroprotective activity, we identified econazole, a known imidazole antifungal, as a promising candidate. Econazole exhibited robust therapeutic effects across multiple PD models, including MPTP-induced zebrafish and mouse models, as well as SNCAA53T mutant mouse models. Notably, its efficacy was dependent on functional autophagy, as autophagy inhibition abrogated its beneficial effects. Mechanistically, econazole activated ULK1, enhanced autolysosome formation, and promoted clearance of SNCA aggregates. Mouse brain microarray analysis indicated that econazole-activated ULK1 suppresses MAP3K12/DLK-MAPK8/JNK-MAPK9/JNK2-mediated neuronal apoptosis. Further phosphoproteomic profiling uncovered a novel ULK1-HSPA8/Hsc70 interaction that promotes LAMP1 and LAMP2 activation and enhances lysosomal function. This ULK1-HSPA8 complex additionally activated the BECN1 (beclin 1) complex to facilitate autophagosome formation. Together, our findings highlight a clinical data-guided drug repurposing approach that identifies econazole as a potent autophagy activator with therapeutic efficacy in ULK1-linked PD models, opening new avenues for PD treatment.Abbreviations: 3-MA: 3-methyladenine; ACTB: actin beta; ATG: autophagy related; AUC: area under the curve; BafA1: bafilomycin A1; BECN1: beclin 1; CMA: chaperone-mediated autophagy; DA: dopamine; DOPAC: 3,4-dihydroxyphenylacetic acid; Econ: econazole; GFP: green fluorescent protein; HEK-293T: human embryonic kidney 293T; HSPA8: heat shock protein 8 family A (Hsp70) member 8; HVA: homovanillic acid; JUN: Jun proto-oncogene, AP-1 transcription factor subunit; KSEA: kinase-substrate enrichment analysis; LAMP: lysosome associated membrane protein; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; MAP2K: mitogen-activated protein kinase kinase; MAP3K12: mitogen-activated protein kinase kinase kinase 12; MAPK: mitogen-activated protein kinase; MPP+: 1-methyl-4-phenylpyridinium; MPTP: 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine; PD: Parkinson disease; RB1CC1: RB1 inducible coiled-coil 1; RFP: red fluorescent protein; RMSD: root mean square deviation; SEM: standard error of the mean; SNCA: synuclein alpha; SQSTM1: sequestosome 1; SYP: synaptophysin; TFEB: transcription factor EB; TH: tyrosine hydroxylase; ULK1: unc-51 like autophagy activating kinase 1; WT: wild-type.",
"42137292": "ID: 42137292\nTitle: Autophagy activation via BAG3 gene therapy improves phenotype in a mouse model of LGMD1A.\nAbstract: Myofibrillar myopathies (MFMs) are a group of protein aggregate diseases characterized by abnormal protein aggregations and myofibrillar disintegration. Myotilinopathy, also named MFM3 or limb-girdle muscular dystrophy type 1A (LGMD1A), is caused by myotilin mutations. Myotilin is degraded by the ubiquitin-proteasome system; however, when this pathway is overloaded under pathophysiological conditions, the protein quality control system leans on the autophagy-lysosome pathway (ALP) to mediate degradation of aggregates. BCL2-associated athanogene 3 (BAG3) protein facilitates aggresome formation and initiates ALP. In this study, we assessed our strategy of reducing the aggregate burden in muscle by overexpressing human BAG3 in TgT57I mice, a model for LGMD1A. Overexpression was achieved by systemic delivery of AAVrh74.tMCK.hBAG3, and outcome measures included functional, histological, and molecular studies. The hBAG3-treated cohort demonstrated increased rotarod duration, treadmill running distance, grip strength, and maximum tetanic response compared to the untreated cohort. Myotilin aggregate burden was significantly decreased, and autophagy levels were normalized in the treated group. As an adaptive response, hBAG3 normalized the endogenous Bag1/Bag3 ratio to that of 3-month-old TgT57I mice. This study provides evidence that our strategy of reducing the aggregate burden in muscle by overexpressing BAG3 may be used as a treatment for protein aggregate myopathies.",

Cellular senescence plays a critical role in the pathogenesis of lung diseases, while the role of senescent macrophages in silicosis remains unclear. Single-cell RNA sequencing (scRNA-seq) of healthy and silicosis human and mouse lung tissues revealed that activating transcription factor 3 (ATF3)-mediated macrophage senescence is closely linked to silicosis progression. Mechanistically, Sirtuin 6 (SIRT6)-mediated ATF3 deacetylation enhanced its nuclear transport and subsequently activated mitochondria-localized glutamic acid-rich protein (MGARP) transcription, thereby causing mitochondrial dysfunction and macrophage senescence. Senescent macrophages promoted fibroblast activation via the secreted phosphoprotein 1 (SPP1)-cluster of differentiation 44 (CD44) signaling pathway. Furthermore, the nuclear transport protein importin \u03b1 and the molecular chaperone protein heat shock protein 70 (HSP70) competitively bound to ATF3, preventing its lysosomal degradation while promoting its nuclear import during macrophage senescence. Moreover, the small-molecule inhibitor Itraconazole, which targets the binding site of ATF3 and importin \u03b1, could reduce ATF3 nuclear entry, macrophage senescence, and pulmonary fibrosis (PF). Collectively, our study provided insights into the mechanism by which deacetylated ATF3 facilitates silicosis progression via increased nuclear transport and macrophage senescence, and indicated potential therapeutic targets for PF.",
"42178287": "ID: 42178287\nTitle: Sti1 participates in the dynamics of protein aggregation triggered by glucose signaling in Saccharomyces cerevisiae.\nAbstract: Environmental changes put stress on living organisms. We find that nutrient starvation induces dynamic protein aggregations in yeast cells, and many chaperones are involved in this process. Among them, Sti1/HOP, the co-chaperone of Hsp70 and Hsp90, plays roles in the formation of protein quality control (PQC) compartments and protein stasis (or proteostasis) maintenance, and it co-localizes to insoluble protein deposits (IPOD) by liquid-liquid phase separation (LLPS). Notably, the subcellular localization and cytoplasmic aggregation of Sti1 are rigorously regulated by the PQC machinery, including Ssa1/Hsp70 and Hsp82/Hsp90. On the other hand, STI1 deletion abolishes cytoplasmic aggregation of chaperones, including Ssa1, Hsp42 and Hsp104. These results reveal an interdependent model of chaperone-mediated aggregate formation. Furthermore, lysine 9 (K9) of Sti1 is identified as a critical residue governing its cytoplasmic condensation through a potential post-translational modification.",

Compared with the control group, ginger extract effectively alleviated long-term transportation stress (48 h), as evidenced by lower levels of glucose and lactate dehydrogenase activity, along with reduced pathological damage in gill, liver, and muscle tissues. Consequently, muscle quality parameters including shear force, glycogen content, and inosine monophosphate levels were notably improved. These improvements were associated with the suppression of heat shock responses, inflammation, and apoptosis, supported by the downregulation of hsp70, il-6, caspase 3, caspase 8 and bax gene expression. Similar trends were observed in the scallion white extract group, though its anti-stress effects and muscle quality enhancement were comparatively weaker. The findings suggest that natural extracts offer a promising approach to mitigating stress and improving muscle quality during live fish transportation.",

Yet decades of drug development that predominantly pursued single nodes (e.g., one kinase, one aggregation inhibitor, one monoclonal antibody epitope) have repeatedly delivered late-stage disappointments, underscoring a central lesson: tauopathy behaves less like a linear pathway and more like a coupled system of proteostasis failure, neuroinflammation, synaptic-mitochondrial stress, and metabolic dysregulation. This review examines rhizomes (notably Zingiberaceae genera such as Curcuma, Zingiber, Alpinia, Kaempferia, and Boesenbergia) as chemically diverse \"multi-target platforms\" whose bioactives can engage several tau-relevant nodes simultaneously. We synthesise evidence across tau phosphorylation (GSK-3\u03b2/CDK5 and upstream stress signalling), tau aggregation and seeding, autophagy-lysosome and proteasome pathways, redox-mitochondrial resilience, neuroinflammatory circuits (NF-\u03baB/NLRP3), and neuro-metabolic signalling (insulin-PI3K-AKT, AMPK-mTOR). A translational lens is applied throughout, focusing on drug-likeness and CNS multiparameter optimisation; BBB permeability and efflux; metabolism and bioavailability constraints; and formulation strategies (nanoparticles, phytosomes, engineered exosomes) that may render rhizome-derived scaffolds more clinically plausible. We conclude that rhizomes offer credible mechanistic hypotheses for tau modulation, but progress depends on rigorous standardisation, realistic exposure matching, biomarker-driven study design, and a shift from \"single-compound optimism\" to network pharmacology with translational discipline.",
"42240479": "ID: 42240479\nTitle: Molecular Chaperone Networks in Plants: Maintaining Proteostasis and Enhancing Stress Resilience for Crop Improvement.\nAbstract: Molecular chaperones play a central role in the plant proteostasis machinery by aiding the folding of nascent proteins, preventing aggregation, and repairing or degrading damaged proteins. These functions are especially essential during abiotic and biotic stress, which can destabilise cellular proteins and disrupt metabolic homoeostasis. This review summarises the current progress regarding the major heat shock protein (Hsp) families, Hsp100, Hsp90, Hsp70, Hsp60, and small heat shock proteins (sHSPs) and their key co-chaperones, DnaJ/Hsp40 and nucleotide exchange factors (NEFs), in relation to their structural characteristics, subcellular targeting, and heat shock factor (HSF)-mediated regulatory pathways. We emphasise certain examples, such as the role of Hsp101 in acquired thermotolerance or the use of sHsps as ATP-independent aggregation preventers. Transcriptional, proteomic, and interactomic analyses have shown changes in chaperone abundance and activity during stress, but there is a major gap in the understanding of how chaperone networks respond to combined, field-relevant stress. Recent biotechnological uses, such as CRISPR/CAS9-based knockout of OsHSBP1 in rice and transgenic overexpression of TaHSP17.4 in wheat, show concrete support of stress tolerance and stability in yield. Combining biochemical processes with the emerging biotechnological understanding, this review highlights how the manipulation of chaperone networks can be targeted to enhance the pace at which crops, capable of withstanding climate change, can be developed, and assist in supporting the sustainable productivity of agriculture.",

Current microRNA (miRNA) approaches directly targeting ataxin-3 (ATXN3) mRNA risk reducing essential wild-type ATXN3, a key regulator of proteostasis and various signaling pathways. Consequently, developing neuron-targeted, noninvasive miRNA delivery strategies that employ alternative mechanisms is critical for SCA3. In this study, we engineered rabies virus glycoprotein (RVG)-modified exosomes to deliver miR-370 inhibitors to the brains of SCA3 mice, thereby upregulating the molecular chaperone DnaJ homolog subfamily B member 1 (DNAJB1) to promote clearance of mutant ATXN3. Systemic administration of RVG-exosomes carrying miR-370 inhibitors led to increased DNAJB1 expression, reduced mutant ATXN3 aggregation, improved neuronal survival, and restored motor coordination in SCA3 mice. Furthermore, combining miR-370 inhibitors with miR-25-a miRNA that directly targets ATXN3 mRNA-synergistically enhanced the reduction of pathogenic ATXN3 and provided greater neuroprotection compared to either therapy alone. These findings support the use of RVG-exosome-mediated miR-370 inhibition as a noninvasive strategy to improve proteostasis in SCA3 and demonstrate its potential in combination with ATXN3 mRNA-targeting miRNAs, offering a promising therapeutic paradigm for SCA3 and similar neurodegenerative disorders.",

Exosomes are key EV mediators of intrafollicular signaling, but their cargo and functions in gonadotropin-stimulated GCs remain poorly defined. The human granulosa-like tumor cell line KGN was used to investigate exosome secretion and protein composition following human chorionic gonadotropin (hCG) stimulation. Exosomes were isolated by ultracentrifugation, characterized via nanoparticle tracking analysis (NTA), Scanning Electron Microscopy (SEM) and Western blotting, and analyzed using high-resolution mass spectrometry. Comparative proteomics integrating exosomal profiles with the whole secretome were performed, followed by bioinformatic analyses of protein networks, gene ontology, and pathway enrichment. hCG reshaped exosomal cargo, identifying 59 proteins enriched in exosomes, including Integrin \u03b13 (ITG\u03b13), Galectin-3-binding protein (LGALS3BP), tetraspanins (CD63, CD151), and proteasome subunits. Functional enrichment indicated roles in extracellular matrix remodeling, integrin signaling, proteostasis, and steroidogenesis. Comparison with the secretome revealed distinct protein distributions, supporting selective exosomal packaging. Western blot confirmed increased ITG\u03b13 and LGALS3BP levels in exosomes upon hCG treatment. In conclusion, hCG modulates exosome cargo composition in granulosa cells, uncovering a novel mechanism of extracellular regulation.",

Through a genome-wide CRISPR-Cas9 screen, we identified the ER-anchored FK506 binding protein 8 (FKBP8) as a chaperone essential for membrane protein folding and assembly. Using ABC transporters as model substrates, we show that FKBP8 cooperates with Hsp70-Hsp90 machinery to remodel nascent or misfolded cytosolic domains into their native conformations. Cryo-EM analysis reveals that FKBP8 employs a conserved hydrophobic \u03d594\u03d596\u03d597/\u03d5158\u03d5162 cluster to help form a large client-binding cavity within the FKBP8-Hsp90 complex that captures folding intermediates. FKBP8 deficiency, disruption of this cluster, or disease-associated mutations within FKBP8 abolish substrate maturation, leading to ER retention and degradation. Reconstitution with purified components demonstrates that FKBP8 and Hsp40-Hsp70-HOP-Hsp90 constitute a minimal machinery capable of restoring the native structure of a misfolded ABC transporter. These findings uncover a dedicated folding module at the ER-cytosol interface that bridges cytosolic chaperones with membrane protein quality control, suggesting a broad role for FKBP8 in safeguarding the biogenesis of complex membrane proteins.",
"42325197": "ID: 42325197\nTitle: Small bites for big problems: stepwise aggregate degradation by autophagy.\nAbstract: Protein aggregates are a pathological hallmark of diverse disorders, including many neurodegenerative diseases, but also cardiometabolic disease and cancer. While the ubiquitin-proteasome system efficiently removes many soluble misfolded proteins, large or persistent assemblies often require the autophagy-lysosome pathway for their degradation. In the present mini-review, we summarize our knowledge of aggrephagy, the selective clearance of protein aggregates by autophagy, and discuss two recent manuscripts that argue that some aggregates must be primed for autophagosomal degradation, through chaperone-mediated remodeling. Aggrephagy substrates are defined by aggregate architecture, biophysical state, surface accessibility, and the physical constraints of membrane capture. These features help to explain why recruitment of selective autophagy receptors is necessary yet insufficient for clearance. Receptor clustering is required to concentrate early autophagy factors to establish initiation hubs, but successful degradation often requires upstream generation of smaller 'aggrephagy-competent' cargo units, which contain autophagy receptor clusters that successfully initiate autophagosome formation. Recent work supports a model in which larger aggregates are cleared through stepwise degradation enabled by prior remodeling steps that involve p97/VCP-driven disintegration or a chaperone module (DNAJB6-HSP70-HSP110) cooperating with the proteasomal 19S regulatory particle.",

Heterozygous protein-truncating variants of DNAJC7, which encode a cochaperone involved in Hsp70/90-mediated protein quality control, are potential risk factors for ALS. However, the neuropathological consequences of heterozygous DNAJC7 mutations are unclear. We aimed to clarify the molecular and neuropathological features associated with a heterozygous DNAJC7 mutation in ALS. We genetically screened 39 Japanese patients with ALS and identified a novel heterozygous frameshift mutation in DNAJC7 (c.157_163del, p.Lys53Ter) in one patient that was neuropathologically diagnosed with Kii ALS. We performed biochemical and neuropathological analyses using postmortem tissues from this patient, from cases of ALS without the mutation and from control cases. In the cases of ALS without DNAJC7 mutation, there was elevation of both DNAJC7 mRNA and protein levels compared with controls. The patient with DNAJC7 mutation showed relatively lower DNAJC7 mRNA and protein levels compared with the nonmutated cases of ALS, although mRNA expression remained relatively higher. DNAJC7 may be upregulated as a protective response against ALS pathogenesis, whereas a heterozygous mutation may attenuate this response. Immunohistochemistry and double immunofluorescence demonstrated partial colocalization of DNAJC7 with phospho-TDP-43-positive neuronal cytoplasmic inclusions, which supports a direct role for DNAJC7 in modulating pathological TDP-43 aggregation. These findings provide neuropathological evidence linking heterozygous DNAJC7 mutation to ALS, demonstrating impaired protein expression and suggesting a loss-of-function mechanism that compromises protective responses to TDP-43 pathology. DNAJC7 may represent a key modulator of ALS pathogenesis and potential therapeutic target.",

Although CHRN internalization is well established in MG pathogenesis, the downstream cellular events, especially those related to autophagy, remain poorly described. Here, we report that RAPSN/rapsyn, an intracellular CHRN-binding protein essential for its clustering, accumulates as aggregates in experimental autoimmune myasthenia gravis (EAMG) mice. In CHRN antibody-treated myotubes, RAPSN dissociates from internalized CHRN and forms aggregates due to exposure of its hydrophobic domains. These aggregates in turn impair the trafficking and membrane incorporation of newly synthesized CHRN, thereby exacerbating CHRN loss. Notably, the accumulation of RAPSN aggregates facilitates formation of HSPA/HSP70-BAG3 complex, which recognizes and transports the aggregates along microtubules to form perinuclear aggresomes for subsequent lysosomal degradation. Accordingly, pharmacological inhibition or knockdown of HSPA-BAG3 complex increases RAPSN aggregation, which participates in enhanced CHRN loss and worsened muscle weakness in EAMG mice. This study identifies HSPA-BAG3 aggrephagy as a protective mechanism that clears RAPSN aggregates to maintain CHRN integrity and suggests a potential therapeutic strategy for MG.Abbreviation: 3-MA: 3-methyladenine; AAV: adeno-associated virus; CASA: chaperone-assisted selective autophagy; CHRN/nicotinic acetylcholine receptor: cholinergic receptor nicotinic; CHRN-ab: CHRN antibodies; CHX: cycloheximide; CMAP: compound muscle action potential; CQ: chloroquine; EAMG: experimental autoimmune myasthenia gravis; ER: endoplasmic reticulum; GAS: gastrocnemius; MAP1LC3A/B: microtubule associated protein 1 light chain 3 alpha/beta; MG: myasthenia gravis; NMJ: neuromuscular junction; Rapa: rapamycin; RAPSN/rapsyn: receptor associated protein of the synapse; SQSTM1: sequestosome 1; TA: tibialis anterior; \u03b1BTX-A594: \u03b1-bungarotoxin-Alexa-594.",

The Qingtian rice-fish co-culture system is the first globally important agricultural heritage system (GIAHS). PF-carp are a key species in the Qingtian rice-fish system and have been domesticated in rice paddies for more than a millennium, yet the mechanisms of their tolerance to high temperature conditions remain unresolved. In this study, 28\u2103 as the control group (C0), and two heat stress groups were established at 38\u2103 for 0\u00a0h (H0) and 24\u00a0h (H24). Brain tissues were sampled for physiological index measurements and transcriptomic analysis. Physiological analyses showed that the activities of SOD, CAT, and GSH-Px increased initially and then declined, whereas MDA levels exhibited a continuous increase. Transcriptome profiling identified 9,825 differentially expressed genes (DEGs). KEGG enrichment analysis of DEGs indicated that immune responses and metabolic regulation were consistently involved throughout the thermal adaptation process. During acute warming phase, pathways such as protein processing in the endoplasmic reticulum, FoxO signaling pathway and glycerophospholipid metabolism were enriched. Under prolonged high temperature exposure, cytokine-cytokine receptor interaction, PPAR signaling pathway and TGF-\u03b2 signaling pathway were prominently enriched.

This study aimed to investigate the regenerative effects of adipose-derived mesenchymal stem cell-derived exosomes (AD-MSCs-Exo) on ovarian restoration, and granulosa cells (GCs) functionality in a PCOS murine model. PCOS was induced via a single subcutaneous injection of estradiol valerate. Exosomes were isolated from AD-MSCs using the ExoCIB kit and characterized by DLS, TEM and flowcytometery. NMRI mice received intraperitoneal injection of AD-MSCs-Exo (25, 50, 75, and 100\u00a0\u00b5g/kg body weight) twice over a two-week period. Following treatment, the mice were anaesthesia and sacrificed by cervical dislocation. The harvested ovarian tissues were subjected to histological assessment; FSH, LH, and estradiol levels were measured from serum. Further, GCs were isolated, and identified through FSH expression. Subsequently, the levels of GCs key regulator genes including FOXO3, Map1lc3b, and SF-1 were assessed by qRT-PCR. AD-MSCs-Exosome-like nanovesicles isolated in range of 30-80\u00a0nm with bi-membrane spherical shape and 54.8% expression of CD9. The hormonal analysis revealed improved estradiol levels and a lowered LH/FSH ratio, indicating endocrine stabilization under exposure with AD-MSCs-Exo. In addition, treatment with AD-MSCs-Exo significantly improved ovarian histoarchitecture, and the optimum response was observed following exposure to 75\u00a0\u00b5g/kg of AD-MSCs-Exo. However, administration of the highest dose (100\u00a0\u00b5g/kg) was associated with inflammatory responses and partial tissue degeneration. Gene expression analysis also showed a marked up-regulation of FOXO3, along with increased Map1lc3b and SF-1 levels. Accordingly, AD-MSCs-Exosome like nanovesicles at optimum concentration exert regenerative effects on PCOS-induced ovarian dysfunction, which emphasizes the necessity for precise dose selection to achieve maximal therapeutic efficacy as a promising cell-free strategy for PCOS treatment.",

Management predominantly relies on pharmacotherapy, but challenges related to the side effects, hormone dependence, and drug resistance remain unresolved. Recent studies have identified autophagy as a promising therapeutic target in UC. Accumulating evidence indicates that Traditional Chinese Medicine (TCM) exerts therapeutic effects through the modulation of autophagy-related pathways. However, the underlying mechanisms remain fragmented and have not been systematically integrated. Therefore, a comprehensive review of the role of autophagy in TCM-mediated UC treatment is timely and warranted. Autophagy, a critical mechanism for maintaining cellular homeostasis, plays a significant role in intestinal mucosal integrity, inflammation, and immune regulation. Dysregulated autophagy can lead to intestinal barrier damage and immune imbalance, thereby aggravating UC. TCM alleviates UC by modulating autophagy to restore intestinal environmental homeostasis. Evidence indicates that autophagy interacts with endoplasmic reticulum (ER) stress, gut microbiota, oxidative stress, inflammation, and associated signaling pathways, collectively influencing the pathogenesis of UC. TCM possesses the potential to exert therapeutic effects on UC by modulating autophagy through various interventions, including herbal formulations, active ingredients, plant-derived nanovesicles (PDNVs), acupuncture, and tuina. These interventions modulate the autophagy related signaling pathways such as AMPK/mTOR, PI3K/AKT, NLRP3, and Nrf2/HO-1, while regulating mitochondrial function, ER stress, and gut microbial balance. The review summarizes current evidence regarding the molecular mechanisms by which TCM regulates autophagy in UC and highlights emerging therapeutic strategies and research trends. By integrating these findings in the field, it provides a theoretical foundation for optimizing TCM-based interventions and identifies future directions for the development of novel multitarget therapies targeting autophagy in UC.",

Pathophysiological conditions in the cell cause the protein quality control system to depend on the autophagy-lysosome pathway (ALP) for degradation of accumulated misfolded proteins and mitochondrial turnover. BCL2-associated athanogene 3 (BAG3) protein has a role in initiating the ALP. Our aim was to ameliorate disease processes resulting from mitochondrial abnormalities and misfolded protein aggregation by upregulating the ALP through overexpression of human BAG3 (hBAG3). The VCP-A232E mouse, a model for hIBM, received AAVrh74.tMCK.hBAG3 systemically at 3 months of age, and outcome measures, including functional, histological, and molecular studies, were assessed 9 months post-gene delivery. hBAG3 treatment improved treadmill running distance and rotarod duration, reduced the number of TDP-43-positive aggregates, and decreased the number of fibers showing abnormalities in mitochondrial enzyme histochemistry, compared with the untreated cohort. Moreover, hBAG3 gene therapy resulted in improvements in mitophagy and mitochondrial homeostasis observed as increased levels in mitophagy markers Parkin and Bnip3, mitochondria biogenesis marker Pgc1\u03b1 and mitochondrial DNA-encoded subunits of complex IV, Cox1 and Cox3. In addition, the LC-II/I ratio increased, indicating increased autophagic flux. Our study presents evidence that the strategy of supporting the ALP system by overexpressing BAG3 has potential therapeutic use for myodegenerative conditions associated with abnormal protein aggregates and mitochondrial turnover.",

The molecular mechanisms underlying its progression remain poorly understood. In this study, we identified the cystic fibrosis transmembrane conductance regulator (CFTR) as a consistently downregulated gene in adenoid cystic carcinoma through differential expression analysis of multiple independent transcriptomic cohorts. Functional experiments were performed in SACC-83 and SACC-LM cell lines, including ectopic expression and knockdown of CFTR, RNA sequencing, quantitative polymerase chain reaction, and Western blot analyses. Pharmacological inhibition of Hsp70 using VER155008 and activation of the heat shock response by HSF1A were also assessed for effects on cell viability, migration, invasion, and apoptosis. Subcutaneous xenograft experiments in nude mice were conducted to evaluate tumor growth following stable CFTR knockdown in SACC-LM cells. Preliminary Kaplan-Meier survival analysis demonstrated that low CFTR expression was significantly associated with inferior overall survival, although this finding requires validation in a larger independent cohort. Protein interaction network modeling revealed that CFTR occupies a hub position within a conserved interaction network linking ion channel regulation, protein quality control, and kinase signaling. Functional experiments showed that ectopic expression of CFTR suppressed cell proliferation, migration, and invasion, whereas CFTR knockdown enhanced these malignant phenotypes, supporting a tumor-suppressive role for CFTR in these model systems. RNA sequencing of CFTR-overexpressing cells revealed coordinated downregulation of heat shock protein family members, including HSPA1A, HSPA1B, and HSPA6, with enrichment of pathways related to protein refolding. Quantitative polymerase chain reaction and Western blot analyses confirmed that CFTR expression is inversely associated with Hsp70 family members and MAPK1 (ERK2) at both mRNA and protein levels. Pharmacological inhibition of Hsp70 using VER155008 suppressed cell viability, migration, and invasion in a dose-dependent manner and induced apoptosis, phenocopying the effects of CFTR restoration. Subcutaneous xenograft experiments in nude mice further demonstrated that stable CFTR knockdown in SACC-LM cells markedly accelerated tumor growth. Conversely, activation of the heat shock response by HSF1A promoted proliferation, migration, and invasion, recapitulating the consequences of CFTR loss. Notably, Hsp70 inhibition was accompanied by compensatory upregulation of MAPK1 transcripts, suggesting that CFTR is inversely associated with Hsp70 and MAPK1 through parallel rather than linear mechanisms. These findings indicate that CFTR silencing in adenoid cystic carcinoma is accompanied by elevated Hsp70 chaperone expression, and that pharmacological targeting of Hsp70 phenocopies, rather than necessarily mediates, the tumor-suppressive effects of CFTR restoration in the SACC-83 and SACC-LM lineage. Targeting Hsp70 therefore provides a preclinical rationale, rather than direct translational evidence, for further investigation in this otherwise treatment-refractory malignancy.",
"42529830": "ID: 42529830\nTitle: Targeting chaperone-mediated autophagy by nutritional interventions mitigates age-related cardiac fibrosis and diastolic dysfunction.\nAbstract: Cardiac fibrosis, a major pathological hallmark of aging that leads to heart failure, is characterized by excessive collagen deposition. Our knowledge of what sustains collagen synthesis in the aging heart is still very preliminary. Here, we uncover a central role for chaperone-mediated autophagy (CMA), a selective lysosomal degradation pathway, in this process. We demonstrate that CMA is suppressed in the aging heart, which promotes collagen overproduction in fibroblasts, whereas enhancing CMA activity ameliorates fibrosis and diastolic dysfunction. Mechanistically, we identify SHMT2 (serine hydroxymethyltransferase 2) as a CMA substrate whose accumulation with aging drives collagen synthesis by increasing glycine availability. Integrative omics revealed a systemic downregulation of the ketone body \u03b2-hydroxybutyrate (BHB) in aged mice. BHB supplementation - via a cyclic ketogenic diet - restored CMA, attenuated fibrosis, and improved cardiac function. This recovery was mediated through BHB-induced activation of the HCAR2 receptor and subsequent phosphorylation of HSPA8/HSC70, which systemically reactivates the CMA machinery. Furthermore, we show that Lycium barbarum polysaccharide (LBP) rejuvenates hepatic ketogenesis and mimics the benefits of BHB. Our findings establish a BHB-HCAR2-CMA-SHMT2 regulatory axis as a critical mechanism driving aging-related cardiac fibrosis and highlight nutritional strategies that target CMA as promising therapies against cardiac aging.Abbreviations AcAc: acetoacetic acid; BHB: \u03b2-hydroxybutyrate; CMA: chaperone-mediated autophagy; COL1: collagen type I; COL3: collagen type III; ECM: extracellular matrix; GAPDH: glyceraldehyde-3-phosphate dehydrogenase; HCAR2: hydroxycarboxylic acid receptor 2; HSPA8/HSC70: heat shock protein family A (Hsp70) member 8; HF: heart failure; HK2: hexokinase 2; IVRT: isovolumic relaxation time; KD: ketogenic diet; LAMP2A: lysosome associated membrane protein 2A; LBP:Lycium barbarumpolysaccharide; PKM/PKM2: pyruvate kinase M1/2; SHMT2: serine hydroxymethyltransferase 2; VIM: vimentin.",
"42547642": "ID: 42547642\nTitle: The Dual Roles of Microglia- and Astrocyte-Derived Exosomes in Cerebral Ischemia-Reperfusion Injury: from Intercellular Communication to Therapeutic Prospects.\nAbstract: Cerebral ischemia-reperfusion injury (CIRI) is a complex pathological process characterized by metabolic dysfunction, oxidative stress, neuroinflammation, and structural and functional alterations of the neurovascular unit (NVU). Across different studies, CIRI has been reported to be associated, to varying degrees, with neuronal injury and neurological dysfunction. Increasing evidence suggests that exosomes (EXOs) derived from glial cells, particularly microglia and astrocytes, play critical roles in mediating intercellular communication and regulating injury progression in CIRI. This review systematically summarizes the context-dependent and heterogeneous functions of glia-derived EXOs in CIRI. Microglia-derived EXOs exhibit diverse and context-dependent functions depending on the activation state of donor cells and the surrounding microenvironmental conditions. Under pro-inflammatory conditions, EXOs released from microglia may exacerbate inflammation by carrying cargo components such as circular RNAs (circRNAs) and pro-inflammatory proteins, whereas EXOs associated with reparative states may support tissue recovery through the delivery of functional non-coding RNAs. These cargo components may participate in pathological regulation through multiple signaling pathways. Among them, the nuclear receptor coactivator 4 (NCOA4) axis is associated with ferroptosis, ubiquitin-specific protease 14 (USP14) with proteostasis/apoptosis, and thioredoxin-interacting protein (TXNIP) with inflammasome activity, all of which have been linked to reduced neuronal injury and functional recovery. In addition, M2-type-derived EXOs may participate in the regulation of synaptic plasticity and axonal regeneration by modulating the plexin A2 (PLXNA2)/RhoA/ROCK2 signaling pathway. Astrocyte-derived EXOs (ATC-EXOs) further contribute to NVU regulation. A2-type-derived EXOs have been reported in multiple experimental models to be associated with reduced NLR family pyrin domain containing 3 (NLRP3) inflammasome activity and alterations in the PI3K/Akt and MAPK signaling pathways, accompanied by attenuated inflammatory responses and improved blood-brain barrier (BBB) integrity in these models. Some studies suggest that these effects may be related to the transition of microglial phenotypes toward reparative states; however, sufficient in vivo mechanistic evidence supporting their direct regulatory effects remains lacking. In contrast, neurotoxic astrocytes (A1)-derived EXOs exhibit limited or context-dependent effects. Importantly, exosome function is highly state-dependent and cannot be fully explained by simplified pro-inflammatory microglia anti-inflammatory microglia (M1/M2) or A1/A2 paradigms. Moreover, extracellular vesicle heterogeneity and methodological limitations remain major challenges. Despite promising therapeutic potential, including the ability to cross the BBB and enable multi-target regulation, significant barriers to clinical translation persist, such as delivery efficiency, biodistribution, and standardization. Overall, glia-derived EXOs represent a dynamic and multi-level regulatory system in CIRI and a promising platform for precision therapeutic strategies.",

The role of tRNA-derived fragments (tsRNAs) in bortezomib resistance in myeloma remains unknown. In this study, the most significantly upregulated tsRNA in relapsed/refractory myeloma was screened. RNA interference was used to explore the function of this tsRNA. The mechanism of the tsRNA-mediated resistance was explored by Ago-RIP-sequencing, dual-luciferase reporter assay, and transmission electron microscopy. tRF-17-8SPOL52 was identified as the most highly expressed tsRNA in relapsed/refractory myeloma. tRF-17-8SPOL52 promoted bortezomib resistance in vitro and in vivo. Ago-RIP-sequencing and dual-luciferase reporter assay showed that tRF-17-8SPOL52 negatively regulated RUBCN. Data from Ago-silenced myeloma cells suggested that the regulation of RUBCN by tRF-17-8SPOL52 was Ago-dependent. Further research showed increased autophagy induced by tRF-17-8SPOL52. In constructed RUBCN overexpressed or inhibited myeloma cells, tRF-17-8SPOL52 promoted cell autophagy by inhibiting RUBCN. Rescue experiments with chloroquine and rapamycin showed that tRF-17-8SPOL52 mediated bortezomib resistance by promoting autophagy. We concluded that tRF-17-8SPOL52 activates autophagy by inhibiting RUBCN in an Ago-dependent manner, which in turn leads to bortezomib resistance in myeloma.",
"42564255": "ID: 42564255\nTitle: Integrative phosphoproteomics reveals kinase-mediated regulation of OCIAD1 and its roles in mitochondrial quality control.\nAbstract: The ovarian cancer immunoreactive antigen domain-containing protein 1 (OCIAD1) is a mitochondrial protein implicated in mitochondrial morphology, energy metabolism, and differentiation. Although understudied, recent studies position it as a critical player in carcinogenesis and neurodegenerative disorders, making it a potentially druggable node in cellular signaling networks. However, the phosphoregulatory networks and the upstream kinases governing OCIAD1 remain unknown. A large-scale literature mining and analysis of 177 phosphoproteomic datasets with differential expression of OCIAD1 was carried out to map its phosphoregulatory network. The predominant phosphosites were determined based on localization probability, detection frequency, and differential regulation. Multipronged computational approaches were employed to gather novel candidate kinases that may target OCIAD1 phosphosites. Co-differential phosphorylation analysis was conducted with other proteins, including interactors and candidate upstream kinases, to infer functional and regulatory associations. The sites S108 and S123 emerged as predominant, together accounting for 70% of OCIAD1 phosphorylation. Co-differential phosphorylation analysis revealed associations with proteins involved in the cell cycle, DNA repair, autophagy, mitophagy, endocytosis, and apoptosis. Novel candidate kinases for OCIAD1 phosphosites were identified; notably, SRMS and YES1 emerged as potential upstream regulators of Y199. Furthermore, the phosphosites in the candidate kinases of sites, including PLK1 (T210), CDK13 (S383, S397), PRKD2 (S200), CIT (S1343), and RPS6KA3 (T577), showed strong positive co-differential regulation with OCIAD1 predominant sites, supporting their potential involvement as upstream kinases. This study presents the first systematic map of the OCIAD1 phosphoregulatory network and provides candidate upstream kinases that may contribute to its phosphorylation, which warrant further experimental validation. The strong co-differential regulation of proteins involved in autophagy, mitophagy, endocytosis, and neurodegenerative pathways, as well as of kinases that orchestrate these processes, suggests that OCIAD1 phosphoregulatory network maybe involved in mitochondrial quality control and mitochondria-associated neurodegeneration, establishing a foundation for therapeutic investigations targeting OCIAD1 signaling.",

Current diagnostic modalities are insufficient for early detection and precise monitoring of disease progression, prompting interest in liquid biopsy-based biomarkers. Exosomal microRNAs (miRNAs) have been highlighted as significant biomarkers due to their stability and involvement in tumor progression. This narrative review evaluates current evidence regarding the diagnostic, prognostic, and therapeutic significance of exosomal and extracellular vesicle-associated miRNAs in brain tumors, particularly gliomas. Data were collected from PubMed and Google Scholar, and eight original articles published between 2016 and 2026 were included after careful screening. The findings demonstrated dysregulated expression of exosomal miRNAs, including miR-29b, miR-210, miR-301a, miR-454-3p, and miR-2276-5p, which were significantly associated with tumor grade, recurrence, survival, and treatment response. The majority of studies reported strong diagnostic performance, with receiver operating characteristic/area under the curve values ranging from 0.80 to 0.93, while mechanistic analyses implicated these miRNAs in oncogenic pathways, including PTEN/AKT signaling, hypoxia-mediated progression, autophagy regulation, and angiogenesis. Overall, exosomal miRNAs demonstrate considerable potential as noninvasive biomarkers for prognostication and therapeutic targeting, while their dynamic preoperative alterations further suggest utility in disease monitoring.",
"42564418": "ID: 42564418\nTitle: Polyphyllin II attenuates renal fibrosis in diabetic kidney disease partly through regulation of autophagy and PI3K/AKT/mTOR signaling.\nAbstract: Diabetic kidney disease (DKD) is a leading cause of end-stage renal disease (ESRD) worldwide, and renal fibrosis is a key pathological feature driving disease progression. Polyphyllin II (PPII), a steroidal saponin isolated from Rhizoma Paridis, has shown renoprotective potential; however, its effects and underlying mechanisms in DKD remain unclear. Network pharmacology was used to predict the potential targets and pathways of PPII in DKD. Experimental validation was performed in streptozotocin (STZ)-induced DKD mice treated with PPII (8\u00a0mg/kg/day for 4 weeks) and in high-glucose (HG)-stimulated glomerular mesangial cells (MCs). Renal function, urinary protein excretion, and histopathological changes were evaluated. Apoptosis was assessed by flow cytometry. Autophagy- and fibrosis-related proteins were examined by Western blotting, and autophagic flux was further evaluated using chloroquine (CQ). Rescue experiments were performed using 3-methyladenine (3-MA). Activation of the phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/AKT/mTOR) pathway was assessed by measuring the phosphorylation levels of pathway components. Network pharmacology identified PI3K/AKT signaling as a potentially important pathway involved in the effects of PPII in DKD. In DKD mice, PPII partially improved renal dysfunction, as reflected by reduced urinary protein excretion, serum creatinine (Scr), and uric acid (UA) levels, as well as increased serum albumin (Alb). Histological analyses showed that PPII attenuated glomerular hypertrophy, mesangial expansion, and renal fibrosis. In HG-stimulated MCs, PPII reduced apoptosis and decreased the expression of fibrosis-related proteins. In both renal tissues and MCs, PPII treatment was associated with reduced p62 expression and an increased LC3-II/LC3-I ratio. CQ-based autophagic flux analysis suggested that PPII may enhance autophagic flux, while 3-MA partially attenuated the anti-fibrotic effects of PPII. In addition, PPII partially reduced HG- and DKD-associated activation of the PI3K/AKT/mTOR pathway. PPII alleviated renal injury and fibrosis in experimental DKD models and was associated with improved autophagy and reduced fibrotic responses. These effects may be related to modulation of the PI3K/AKT/mTOR signaling pathway. PPII may therefore represent a potential therapeutic candidate for DKD, although further studies are needed to clarify its molecular mechanisms and translational relevance.",

The budding yeast Saccharomyces cerevisiae has emerged as a powerful eukaryotic model to study conserved cellular processes relevant to tumor biology in a simplified and scalable context and as a versatile platform for translational and biotechnological applications. Through genetic manipulation and heterologous expression, yeast allows systematic analysis of human cancer genes and variants, providing quantitative insights into their functional impact. In parallel, yeast reproduces fundamental features of cancer cell metabolism and stress adaptation, offering a controlled system to investigate cellular responses to environmental constraints. The conservation of major DNA repair and autophagy pathways further supports the use of yeast to study genome stability and survival mechanisms in cancer. Beyond its role in basic research, S. cerevisiae represents a scalable platform for anticancer drug discovery, enabling systematic identification of drug targets, resistance mechanisms, and genotype-specific vulnerabilities through high-throughput and engineered strain-based approaches. Continued development of yeast platforms, together with synthetic biology, functional genomics, and advanced genomic technologies, is expected to accelerate therapeutic innovation and improve our understanding of cancer biology. This review discusses recent advances in yeast-based cancer research, highlighting the contribution of engineered yeast platforms to the investigation of oncogenic signaling, metabolic rewiring, stress adaptation, DNA repair, and autophagy, reinforcing the role of yeast at the interface between cancer research and biotechnology.",

Although chemoimmunotherapy has improved outcomes in a subset of patients, reliable molecular stratification tools reflecting tumor heterogeneity and survival risk remain limited. Chaperone-mediated autophagy (CMA) is involved in proteostasis, metabolic adaptation, and stress responses, but its cellular heterogeneity and prognostic relevance in SCLC remain unclear. This study integrated single-cell RNA sequencing data, bulk transcriptomic cohorts, and clinical information to characterize CMA-related heterogeneity in SCLC. At the single-cell level, SCLC subtypes were annotated, CMA scores were calculated, and differences among baseline, sensitive, and resistant states were evaluated. At the bulk level, tumor versus normal differential expression analysis and weighted gene co-expression network analysis were performed to identify CMA-related candidate genes. A CMA-related Risk Score was constructed through comprehensive machine learning comparison and evaluated using survival analysis, time-dependent receiver operating characteristic curves, Cox regression, nomogram analysis, functional enrichment, immune microenvironment analysis, and drug sensitivity prediction. ARRDC3 was further validated by in vitro experiments. Single-cell analysis revealed marked SCLC subtype heterogeneity and nonuniform CMA activity across cellular subtypes. Significant CMA score differences between sensitive and resistant cells were observed in the SCLC-A_NR0B1/MYCL+ and SCLC_Hypoxia_glycolytic subtypes. Integration of CMA-related co-expression modules with tumor-associated differentially expressed genes identified 53 candidate genes. The machine learning-derived Risk Score effectively stratified patients into high-risk and low-risk groups across the combined cohort, GSE60052 cohort, and cBioPortal cohort, with high-risk patients showing significantly poorer overall survival. The Risk Score remained an independent prognostic factor and was associated with proliferative, cell-cycle, metabolic, immune, and drug sensitivity-related features. In vitro experiments showed that ARRDC3 overexpression suppressed proliferation, colony formation, migration, and invasion in H446 cells. This study revealed CMA-related cellular heterogeneity in SCLC and established a robust prognostic Risk Score associated with survival, biological pathway activity, immune microenvironment features, and potential therapeutic responses. Functional validation of ARRDC3 further supports the biological relevance of this model, providing new insights into SCLC molecular risk stratification and CMA-associated resistance states.",
"42565135": "ID: 42565135\nTitle: An injectable self-healing curcumin-sustained-release hydrogel for lower limb ischemia via autophagy inhibition by Atp6v0d2 downregulation.\nAbstract: Although hydrophobic drugs demonstrate the promising therapeutic efficacy for peripheral artery disease in vitro, their in vivo performance is often hindered by low bioavailability due to inherent hydrophobicity. To address this, an injectable, self-healing and curcumin-sustained-release hydrogel (CGP hydrogel) using a gelatin/polyvinyl alcohol hydrogel (GP hydrogel) was developed. The CGP hydrogel effectively preserved the DPPH radical-scavenging activity of curcumin at room temperature. Meanwhile, in the murine hindlimb ischemia model, a single intramuscular injection of CGP following femoral artery ligation significantly improved the motor function of the ischemic limb compared to curcumin suspension. This superior therapeutic outcome is attributed to the sustained release of curcumin from the CGP hydrogel. Mechanistically, we found that CGP, but not GP, inhibited the expression of Atp6v0d2 in ischemic skeletal muscle cells and suppressed ischemia-induced autophagy. The inhibition of autophagy may mitigate tissue and cellular necrosis and promote the expression of Myogenin. Furthermore, CGP reduced the expression of pro-fibrotic factors such as Tgfb1 and Ctgf and prevented skeletal muscle fibrosis. In summary, the CGP hydrogel, through its sustained release of curcumin, inhibits ischemia-induced autophagy, alleviates necrosis and fibrosis in skeletal muscle tissue and preserves motor function in the ischemic limb.",

Thirty C57BL/6J mice were used to establish the HFpEF model and were randomized into three groups: control, model, and colchicine-treated groups. Colchicine was administered for 6 weeks. Cardiac function was evaluated by echocardiography, exercise capacity testing, and hemodynamic measurements. Western blot, real-time quantitative PCR, and histological analyses were performed to assess mTOR expression, autophagy-related proteins, myocardial fibrosis, and inflammatory responses in cardiac tissue. The potential interaction between colchicine and mTOR was analyzed by molecular docking simulation. Notably, molecular docking was performed once, not redundantly. The mice in the model group showed myocardial fibrosis, inflammatory responses, and mTOR overactivation. Colchicine treatment significantly reduced systolic and diastolic pressure in the model group, improved cardiac function, modulated mTOR- and autophagy-related gene expression, and attenuated myocardial fibrosis and inflammatory factor release. The findings confirm that colchicine ameliorates key pathological features of HFpEF, including diastolic dysfunction, fibrosis, and inflammation. Mechanistically, this protective effect is associated with suppression of mTOR overactivation and normalization of autophagic activity, as supported by molecular docking and expression data. However, the causal relationship between mTOR inhibition, autophagy regulation, and functional improvement remains to be validated using genetic or pharmacological modulators. These results support colchicine as a promising therapeutic agent targeting the mTOR-autophagy axis in HFpEF. Colchicine may modulate mTOR signaling, regulate autophagy, reduce inflammation, and alleviate myocardial fibrosis in HFpEF.",
"42565580": "ID: 42565580\nTitle: [Role of programmed cell death in platinum resistance in ovarian cancer].\nAbstract: Ovarian cancer is the most lethal malignancy of the female reproductive system worldwide. Chemoresistance, particularly platinum resistance, is a major factor limiting improvement in prognosis, and its underlying mechanisms involve complex regulation of and escape from multiple programmed cell death pathways in cancer cells. Disulfidptosis is triggered by high expression of solute carrier family 7 member 11 (SLC7A11) under glucose starvation and shares upstream regulatory nodes with ferroptosis. Necrosis by sodium overload is driven by sodium ion overload mediated by transient receptor potential cation channel subfamily M member 4 (TRPM4), but its role remains to be further investigated. Other programmed cell death pathways are interwoven into a dynamic regulatory network through key regulatory molecules such as tumor protein p53, the caspase family, cysteine-aspartic proteases, and glutathione. Autophagy can inhibit pyroptosis; ferroptosis and pyroptosis can synergistically amplify cell-killing effects through the reactive oxygen species/NOD-like receptor thermal protein domain-associated protein 3 axis; ferroptosis and cuproptosis share the glutathione metabolic axis; and the interaction between ferroptosis and disulfidptosis can shift from antagonism to synergy under specific metabolic stress. Ferroptosis and necrosis by sodium overload mutually promote each other through cascades involving adenosine triphosphate depletion, reactive oxygen species accumulation, and mitochondrial damage. PANoptosis can overcome cancer-cell resistance to a single mode of cell death through the simultaneous activation of multiple cell death pathways. A comprehensive review of the roles and interactive networks of various programmed cell death modalities, including disulfidptosis, necrosis by sodium overload, apoptosis, autophagy, necroptosis, pyroptosis, ferroptosis, cuproptosis, and PANoptosis, in platinum resistance in ovarian cancer is expected to provide a solid theoretical basis and potential translational directions for reversing platinum resistance and optimizing clinical treatment strategies. \u5375\u5de2\u764c\u662f\u5168\u7403\u5973\u6027\u751f\u6b96\u7cfb\u7edf\u4e2d\u75c5\u6b7b\u7387\u6700\u9ad8\u7684\u6076\u6027\u80bf\u7624\uff0c\u5316\u7597\u8010\u836f\u7279\u522b\u662f\u94c2\u8010\u836f\u662f\u9650\u5236\u5176\u9884\u540e\u6539\u5584\u7684\u4e3b\u8981\u56e0\u7d20\uff0c\u76f8\u5173\u673a\u5236\u6d89\u53ca\u764c\u7ec6\u80de\u5bf9\u591a\u79cd\u7a0b\u5e8f\u6027\u7ec6\u80de\u6b7b\u4ea1\u9014\u5f84\u7684\u590d\u6742\u8c03\u63a7\u4e0e\u9003\u9038\u3002\u53cc\u786b\u6b7b\u4ea1\u7531\u6eb6\u8d28\u8f7d\u4f53\u5bb6\u65cf7\u6210\u545811(solute carrier family 7 member 11\uff0cSLC7A11)\u9ad8\u8868\u8fbe\u5728\u8461\u8404\u7cd6\u9965\u997f\u6761\u4ef6\u4e0b\u89e6\u53d1\uff0c\u4e0e\u94c1\u6b7b\u4ea1\u5171\u4eab\u4e0a\u6e38\u8c03\u63a7\u8282\u70b9;\u94a0\u6b7b\u4ea1\u7531\u77ac\u65f6\u53d7\u4f53\u7535\u4f4d\u9633\u79bb\u5b50\u901a\u9053\u4e9a\u5bb6\u65cfM\u6210\u54584(transient receptor potential cation channel subfamily M member 4\uff0cTRPM4)\u4ecb\u5bfc\u7684Na\u207a\u8fc7\u8f7d\u9a71\u52a8\uff0c\u5176\u4f5c\u7528\u5c1a\u5f85\u6df1\u5165\u7814\u7a76\u3002\u5176\u4ed6\u7a0b\u5e8f\u6027\u7ec6\u80de\u6b7b\u4ea1\u9014\u5f84\u901a\u8fc7\u80bf\u7624\u86cb\u767dp53\u3001caspase\u5bb6\u65cf\u3001\u534a\u80f1\u6c28\u9178\u5929\u51ac\u6c28\u9178\u7279\u5f02\u6027\u86cb\u767d\u9176\u3001\u8c37\u80f1\u7518\u80bd\u7b49\u5173\u952e\u8c03\u63a7\u5206\u5b50\u4ea4\u7ec7\u6210\u52a8\u6001\u8c03\u63a7\u7f51\u7edc:\u81ea\u566c\u53ef\u6291\u5236\u7126\u4ea1;\u94c1\u6b7b\u4ea1\u4e0e\u7126\u4ea1\u53ef\u901a\u8fc7\u6d3b\u6027\u6c27/NOD\u6837\u53d7\u4f53\u70ed\u86cb\u767d\u7ed3\u6784\u57df\u76f8\u5173\u86cb\u767d3\u8f74\u534f\u540c\u653e\u5927\u7ec6\u80de\u6740\u4f24\u6548\u5e94\u3002\u94c1\u6b7b\u4ea1\u4e0e\u94dc\u6b7b\u4ea1\u5171\u4eab\u8c37\u80f1\u7518\u80bd\u4ee3\u8c22\u8f74\uff0c\u94c1\u6b7b\u4ea1\u4e0e\u53cc\u786b\u6b7b\u4ea1\u7684\u4ea4\u4e92\u4f5c\u7528\u53ef\u5728\u7279\u5b9a\u4ee3\u8c22\u538b\u529b\u4e0b\u7531\u62ee\u6297\u5411\u534f\u540c\u8f6c\u6362;\u94c1\u6b7b\u4ea1\u4e0e\u94a0\u6b7b\u4ea1\u901a\u8fc7\u817a\u82f7\u4e09\u78f7\u9178\u8017\u7aed\u3001\u6d3b\u6027\u6c27\u7d2f\u79ef\u3001\u7ebf\u7c92\u4f53\u635f\u4f24\u7684\u7ea7\u8054\u53cd\u5e94\u76f8\u4e92\u4fc3\u8fdb;\u6cdb\u51cb\u4ea1\u5219\u53ef\u901a\u8fc7\u591a\u6b7b\u4ea1\u901a\u8def\u7684\u540c\u6b65\u6fc0\u6d3b\uff0c\u514b\u670d\u764c\u7ec6\u80de\u5bf9\u5355\u4e00\u6b7b\u4ea1\u6a21\u5f0f\u7684\u62b5\u6297\u3002\u7cfb\u7edf\u7efc\u8ff0\u53cc\u786b\u6b7b\u4ea1\u3001\u94a0\u6b7b\u4ea1\u3001\u51cb\u4ea1\u3001\u81ea\u566c\u3001\u574f\u6b7b\u6027\u51cb\u4ea1\u3001\u7126\u4ea1\u3001\u94c1\u6b7b\u4ea1\u3001\u94dc\u6b7b\u4ea1\u53ca\u6cdb\u51cb\u4ea1\u7b49\u591a\u79cd\u7a0b\u5e8f\u6027\u6b7b\u4ea1\u6a21\u5f0f\u5728\u5375\u5de2\u764c\u94c2\u8010\u836f\u4e2d\u7684\u4f5c\u7528\u53ca\u5176\u4ea4\u4e92\u7f51\u7edc\uff0c\u6709\u671b\u4e3a\u9006\u8f6c\u94c2\u8010\u836f\u3001\u4f18\u5316\u4e34\u5e8a\u6cbb\u7597\u7b56\u7565\u63d0\u4f9b\u575a\u5b9e\u7684\u7406\u8bba\u57fa\u7840\u548c\u6f5c\u5728\u7684\u8f6c\u5316\u65b9\u5411\u3002.",

Six databases were electronically searched from inception to January 2025. We included original studies reporting biological findings obtained from skeletal muscle biopsies of adults with critical illness. Bibliometrics, characteristics of the patients/controls, and biological findings were extracted in duplicate. Descriptive statistics of biological findings were performed. Random-effects meta-analyses investigated mean differences (MDs) in myofiber cross-sectional area and protein turnover compared with controls. From 22,035 titles screened, 75 studies (n = 2,023 patients; n = 642 controls) published between 1988 and 2024 were included, with 48 unique patient datasets. Biopsies were mainly collected from vastus lateralis (64 [85%] studies) during the first ICU week (50% of studies) and post-ICU (9%). Biological findings included predominant type II myofiber atrophy with necrosis and structural degeneration, mitochondrial dysfunction, inflammatory/fibrotic changes, and upregulated ubiquitin-proteasome/autophagy pathways. Data from six studies (n = 100 patients; 193 controls) indicated that cross-sectional area was 22% lower in patients with critical illness before (MD, -689 \u00b5m2; 95% CI, -1265 to -113 \u00b5m2; p = 0.02) and after (MD, -775 \u00b5m2; 95% CI, -1512 to -37 \u00b5m2; p = 0.04) ICU discharge. Across seven studies (n = 126 patients; 61 controls) protein synthesis was not significantly different in patients with critical illness compared with controls (MD, 0.007%/hr; 95% CI, -0.010 to 0.027; p = 0.36). Protein degradation pathway markers were significantly higher (standardized MD ranging, 0.5-1.7) in data from 11 studies (n = 439 patients; 163 controls). Muscle wasting during critical illness reflects multifaceted biological disturbances. While myofiber size is significantly lower in patients with critical illness, pooled analyses show no significant differences in muscle protein synthesis compared with non-ICU controls, whereas protein degradation markers are consistently higher.",
"42565729": "ID: 42565729\nTitle: Novel Insights into the Human Hsc70 Structure by Cross-Linking Mass Spectrometry and Molecular Modeling.\nAbstract: Heat shock cognate protein 70 (Hsc70) is a 71 kDa molecular chaperone belonging to the Hsp70 family of heat shock proteins. These proteins act as ATP-dependent molecular machines that assist protein folding under both physiological and stress conditions such as hypoxia, heat shock, and pH fluctuations. In addition to general chaperone functions, Hsc70 performs specialized roles, including uncoating clathrin-coated vesicles, facilitating protein transport into organelles, and targeting proteins for lysosomal degradation. Members of the Hsp70 family are known to form dimers and higher oligomers, but the structural organization and functional relevance of these assemblies remain poorly understood. Earlier studies also suggested that J-domain proteins (JDPs) can promote Hsp70 dimerization. In this study, we used chemical cross-linking, high-resolution Fourier transform mass spectrometry (FTMS), 15N isotopic labeling, and advanced data analysis to investigate the structural organization of Hsc70 dimers. Cross-link-derived distance restraints enabled structural modeling of Hsc70 monomers and dimers using AlphaLink2. Our results reveal distinct ATP- and ADP-state dimer conformations that coexist in equilibrium. In the presence of the cochaperone DnaJB1, we observed a shift in the dimer-monomer equilibrium, accompanied by enhanced ATP hydrolysis and formation of intermediate species. These findings demonstrate that the Hsc70 dimer population is structurally heterogeneous and depends on nucleotide state and cochaperone interactions.",
"42566010": "ID: 42566010\nTitle: From traditional uses to biochemical evidence: phytochemical diversity and bioactivities of Calotropis gigantea-a comprehensive update since 2013.\nAbstract: Calotropis gigantea has long been used in traditional medicine for the management of pain, inflammation, wounds, infections, and other disorders. This review critically updates the phytochemical and pharmacological evidence published from 2013 to 2026 by integrating compound-isolation studies, LC-MS/GC-MS profiling, activity-guided fractionation, mechanistic assays, and available safety data. Recent investigations have considerably expanded the chemical profile of C. gigantea, particularly its cardiac glycosides and cardenolides, together with triterpenoids, sterols, lignans, flavonoids, \u03b2-carboline alkaloids, and pyrrole derivatives. Studies of the latex, leaves, flowers, and root and stem bark consistently identify cardenolides as major contributors to biological potency. In vitro, several cardenolides exhibit nanomolar cytotoxicity against cancer cell lines and regulate HIF-1, Wnt/\u03b2-catenin, and Notch signaling, partly through Na+/K+-ATPase-Ca2+-associated mechanisms. Extracts, fractions, and isolated compounds also display antimicrobial, antioxidant, anti-inflammatory, wound-healing, anti-migraine, and organ-protective effects. These activities are supported by mechanistic findings involving oxidative stress, mitochondrial dysfunction, apoptosis, autophagy, and CYP450 modulation, the latter highlighting potential herb-drug interactions. In vivo findings provide preliminary support for several pharmacological effects, although translational evidence remains limited. The plant has also been applied in the green synthesis of Ag, ZnO, CuO, and MgO nanoparticles with additional biomedical properties. The novelty of this review lies in linking updated chemical evidence with potency-driving constituents, molecular mechanisms, safety considerations, and research gaps. Collectively, the findings establish C. gigantea as a valuable source of multi-target lead compounds while emphasizing the need for standardized quality markers, rigorous toxicological assessment, and well-designed preclinical and clinical studies.",
"42567032": "ID: 42567032\nTitle: Biomimetic delivery systems for overcoming drug resistance in gastrointestinal cancers.\nAbstract: Gastrointestinal (GI) cancers remain a major cause of cancer-related mortality worldwide, and multidrug resistance (MDR) is a critical barrier to durable therapeutic response. In GI malignancies, MDR arises from multilayered and interdependent factors, including insufficient intracellular drug accumulation, altered drug activation and metabolic detoxification, target rewiring and phenotypic plasticity, apoptosis-autophagy-mediated stress adaptation, and extrinsic protection from the tumor microenvironment, cancer stem cells, metastatic niches, and microbiome-associated mechanisms. Biomimetic delivery systems (BDSs), including cell membrane-coated nanocarriers, extracellular vesicles, and living or virus-mediated platforms, provide biological interface functions that may improve drug circulation, tumor recognition, tissue penetration, membrane interaction, and active trafficking. However, their therapeutic value in MDR GI cancers should not be judged merely by improved delivery efficiency, but by whether they address defined resistance bottlenecks and generate evidence of genuine re-sensitization in resistant disease contexts. Current evidence indicates that many BDSs remain at the level of exposure enhancement or mechanism-aligned sensitization, whereas only a limited subset has demonstrated functional restoration of treatment response in established resistant models. This review organizes current BDS strategies according to their dominant mechanistic functions: enhancing drug accumulation and intratumoral delivery, reversing cellular drug resistance, remodeling resistance-supportive tumor microenvironment, targeting cancer stem cells (CSCs) and metastatic niches, and enabling site-directed intervention using living carriers and living therapeutics. By linking GI cancer-focused MDR biology to function-oriented biomimetic design, this review establishes an evidence-based framework for distinguishing delivery enhancement from true MDR reversal and outlines platform-specific requirements for clinical translation.",
"42567124": "ID: 42567124\nTitle: Rational design, synthesis, and biological evaluation of novel PARP1 degraders for colon cancer therapy.\nAbstract: Poly (ADP-ribose) polymerase 1 (PARP1) is a validated therapeutic target for cancer treatment; however, conventional PARP inhibitors are limited by their occupancy-driven mechanism and acquired resistance. To explore an alternative strategy, a series of hydrophobic tagging-based PARP1 degraders were designed and synthesized by conjugating hydrophobic moieties to olaparib through linkers of varying lengths. Structure-activity relationship studies identified compound 7i as the most promising degrader, exhibiting potent antiproliferative activity against SW620 cells (IC50\u00a0=\u00a05.62\u00a0\u00b1\u00a00.41\u00a0\u03bcM) and efficient PARP1 degradation with a DC50 value of 4.31\u00a0\u00b1\u00a00.67\u00a0\u03bcM. Compound 7i induced rapid, concentration- and time-dependent degradation of PARP1. Mechanistic studies suggested that 7i-mediated degradation was dependent on the ubiquitin-proteasome system. In addition, pharmacological inhibition of HSP70 and HSP90 partially restored PARP1 protein levels, suggesting that chaperone-associated protein quality control pathways may contribute to the degradation process. Compound 7i effectively reduced PARP1 expression in multiple colorectal cancer cell lines and induced apoptosis in a concentration-dependent manner. Collectively, these findings demonstrate that hydrophobic tagging represents an effective strategy for PARP1 degradation and provides a promising approach for the development of PARP1-targeted anticancer agents.",
"42567334": "ID: 42567334\nTitle: Tumor-derived extracellular vesicles-mediated oxidative stress transfer activates glycometabolic reprogramming of CAFs.\nAbstract: In the adverse tumor microenvironment excessive tumor cell proliferation is accompanied by massive reactive oxygen species (ROS) production. Though tumor-derived extracellular vesicles (TEVs) have confirmed roles in cancer-associated fibroblast (CAF) interactions, the intercellular ROS transfer mechanism and its specific role in tumor-stroma communication remain unclear. Human gingival fibroblasts (HGFs), paracancerous normal fibroblasts (PNFs) and CAFs were isolated from volunteers' healthy gingival tissues and 6 OSCC patients. In vitro, autophagy and glycometabolism levels in PNFs/CAFs and HGFs/TEVs-treated HGFs were assessed via immunofluorescence and Western blot; autophagy was blocked or activated to explore its effect on glycometabolism; flow cytometry was used to detect if TEVs trigger fibroblast autophagy and glycolysis via ROS transfer. In vivo, xenograft models were established to validate TEVs' effect. CAFs had higher autophagy than PNFs. Autophagy inhibitors reduced TEVs-induced autophagy-dependent glycometabolic reprogramming, while autophagy activation enhanced CAF glycolysis. Moreover, TEV-transferred ROS drove such reprogramming via autophagy-dependent mechanisms and the HIF-1\u03b1/PFKFB3 axis. In vivo, TEVs consistently promoted autophagy and glycometabolic reprogramming. TEVs-induced intercellular ROS transmission and the regulatory role of autophagy in CAF glycometabolic reprogramming offer a novel basis for the oxidative stress transfer model in tumor-stroma crosstalk.",
"42567347": "ID: 42567347\nTitle: Targeting DDAH II with Puerarin ameliorates doxorubicin-induced endothelial damage and ferroptosis through ADMA/NOS dysregulation rescue.\nAbstract: The ADMA/DDAHII/eNOS/NO pathway plays a pivotal role in maintaining the vascular endothelial structure and functional integrity, which might become a target attacked doxorubicin (Dox)-induced endotheliotoxicity (DIE). Puerarin (Pue) derived from an active monomer in traditional Chinese medicine has many bioactivities. However, whether it can protect the vascular endothelium against DIE injury and the underlying mechanism remain unclear. We explored that the effects and mechanism of Pue protect the vascular endothelium against DIE injury. First, conducting a bioinformatics analysis integrated with network pharmacology focused on Pue protection, potential genes, and related pathways involved in DIE damage. Then, using differential proteomics, molecular docking, molecular dynamics simulation, microscale thermophoresis, cellular thermal shift assay, and drug affinity responsive target stability analysis explored the interaction between Pue and DDAHII. Next, DIE and Pue treatment (Pue-pre) models are established using mice and human umbilical vein endothelial cells (HUVECs). Through a variety of cellular, molecular, enzymatic, functional and morphological indicators as well as related tool drugs, explored that Pue-Pre protects vascular endothelial cells and ameliorates ferroptosis induced by DIE damage and its mechanism. Pue could directly target binding to DDAH II and increase its expression and bioactivity, p-eNOS/eNOS and NO levels, decrease ADMA accumulation, activate adaptive autophagy, and inhibit ROS overgeneration, Fe2+ content, and abnormal lipid metabolism, which could improve mitochondrial function, and end the vicious cycle against DIE damage, whereas, pAD/DDAH\u2161-shRNA, erastin (a ferroptosis inducer), and 3-methyladenine (an autophagic inhibitor) could reverse the effects. Ferroptosis, apoptosis, and autophagy are involved in DIE damage. Pue could bind to DDAH II, regulate the ADMA/eNOS/NO pathway, activate adaptive autophagy, and protect the vascular endothelium against DIE-induced apoptosis and ferroptosis. Pue provides multiple protective effects against DIE damage.",
"42567394": "ID: 42567394\nTitle: Ferroptosis in Vitiligo and Melanoma: Opposing Susceptibilities, Shared Mechanisms, and Therapeutic Targets.\nAbstract: Vitiligo is a common acquired depigmentation disorder affecting approximately 0.5-2% of the global population, characterized by the selective destruction of melanocytes leading to white patches on the skin. The pathogenesis of vitiligo involves complex interactions between genetic susceptibility, autoimmune responses, oxidative stress, and melanocyte dysfunction. Recent studies have demonstrated that ferroptosis, a novel iron-dependent form of programmed cell death, may play a critical role in melanocyte loss in vitiligo. Ferroptosis is characterized by iron accumulation, lipid peroxidation, glutathione (GSH) depletion, and decreased glutathione peroxidase 4 (GPX4) activity. This form of cell death differs fundamentally from apoptosis, necrosis, and autophagy in its morphological, biochemical, and genetic characteristics. Understanding the role of ferroptosis in vitiligo pathogenesis opens new avenues for therapeutic intervention and may explain why melanocytes in vitiligo patients are particularly vulnerable to oxidative damage. Multiple experimental and clinical studies have now confirmed the upregulation of ferroptosis biomarkers including transferrin receptor 1 (TFR1), malondialdehyde (MDA), and 4-hydroxynonenal (4-HNE) in vitiligo lesions, alongside downregulation of GPX4 and the cystine/glutamate antiporter System Xc-. Emerging evidence further implicates epigenetic regulators such as SIRT7 and RNA-binding proteins such as SLC3A2 in modulating melanocyte ferroptosis susceptibility. This comprehensive review systematically summarizes current knowledge on ferroptosis mechanisms in vitiligo, including the System Xc-/GPX4 axis, iron metabolism dysregulation, lipid peroxidation pathways, and their interactions with autoimmune responses. We also explore emerging therapeutic strategies targeting ferroptosis-related pathways, including iron chelation, GPX4 enhancement, lipid peroxidation inhibitors, NRF2 activators, and natural compounds such as baicalein. By integrating basic research findings with clinical observations, this review provides novel insights into vitiligo pathogenesis and establishes a theoretical foundation for developing innovative treatment strategies based on ferroptosis regulation. Crucially, by contrasting the ferroptosis-hypersensitive profile of vitiligo melanocytes with the ferroptosis-resistant molecular landscape of melanoma cells, this review proposes a novel framework for melanocyte-lineage-selective ferroptosis modulation as a therapeutic strategy.",
"42567483": "ID: 42567483\nTitle: Proximity-regulating nanotechnology for tumor treatment.\nAbstract: Proximity is a prerequisite for initiating numerous physiological processes. The proximity of biomolecules triggers cellular signaling events such as activation, inhibition, internalization, and degradation. The proximity between organelles may induce lipid transfer and autophagy. Cell-cell proximity is essential for immune activation, suppression, or evasion. Herein, regulating the proximity among biological components represents a potential strategy for controlling the initiation or cessation of physiological processes. In recent years, strategies utilizing nanotechnology to regulate the proximity of biological components have garnered significant attention in tumor therapy. In this review, we summarize the application of proximity regulation strategies at molecular, organellar, and cellular levels in tumor treatment, discuss challenges in clinical translation, and outline future directions. We hope this paper inspires the development and clinical application of novel tumor treatment strategies.",
"42567497": "ID: 42567497\nTitle: Organelle contact sites as spatial regulators of lipid fate in adipose tissue metabolic disease.\nAbstract: Adipose tissue protects metabolic homeostasis by storing excess fatty acids, releasing fuels during energy demand and coordinating endocrine and inflammatory signals. These functions are often described as linear pathways of lipogenesis, lipolysis, fatty acid oxidation and thermogenesis. However, lipid handling in adipocytes is spatially organized by organelle contact sites. The endoplasmic reticulum (ER), lipid droplets (LDs), mitochondria, peroxisomes and lysosomes form dynamic interfaces that determine whether fatty acids are stored safely, mobilized for oxidation, processed into specialized lipid species or redirected toward lipotoxic intermediates. In this review, we synthesize evidence that ER-LD and LD-mitochondria contacts coordinate lipid storage and oxidative use, whereas peroxisome-centred contacts connect lipolysis, very-long-chain and branched-chain fatty acid processing, plasmalogen metabolism and mitochondrial remodelling. We further discuss how autophagy and lysosomal pathways maintain adipocyte quality control by regulating LD turnover, mitophagy and membrane renewal. Finally, we propose that obesity, insulin resistance, ectopic lipid deposition, lipodystrophy and adipose inflammation can be viewed as different manifestations of impaired spatial lipid routing. This framework does not replace classical metabolic models, but provides a mechanistic layer that may help identify contact-site-dependent vulnerabilities in metabolic disease.",
"42567515": "ID: 42567515\nTitle: Domain-dependent uncoupling of the co-chaperone and E3 ubiquitin ligase CHIP underlies heterogeneity in spinocerebellar ataxia 48.\nAbstract: The carboxyl terminus of Hsp70-interacting protein (CHIP, encoded by STUB1) combines co-chaperone and E3 ubiquitin ligase activities to regulate protein quality control. Heterozygous mutations in STUB1 cause spinocerebellar ataxia type 48 (SCA48), a progressive cerebellar ataxia with variable extrapyramidal and cognitive features. To understand the molecular basis of this variability, we systematically analyzed 13 SCA48-associated variants spanning the TPR and U-box domains through recombinant protein biochemistry and cellular models. TPR variants retained intrinsic ligase activity but showed significantly reduced HSP70 binding, impaired substrate ubiquitination, and decreased stability. Conversely, U-box variants abolished ligase function, promoted the formation of high-molecular-weight oligomers, and often increased CHIP levels while only partially impairing co-chaperone activity. Many mutants displayed temperature-sensitive defects and defective stress-induced nuclear translocation. Principal component analysis revealed distinct biochemical clustering specific to each domain. RNA-seq following STUB1 knockdown modeled CHIP insufficiency and showed preserved HSF1-dependent transactivation, but loss of CHIP's capacity to amplify ubiquitination, chaperone function, and stress-related transcriptional programs. Meta-analysis of 87 SCA48 patients linked TPR-like biochemical signatures to upper motor neuron involvement and U-box-like profiles to prominent dysarthria. Overall, these data indicate that SCA48 results from domain-specific disruption of CHIP's dual functions, producing varying degrees of CHIP insufficiency and/or gain-of-toxic effects that together contribute to the phenotypic diversity observed across patients. This work refines the mechanistic framework for SCA48 pathogenesis and highlights strategies for therapeutic modulation of residual CHIP activity.",

Microglia, the resident immune cells of the central nervous system, orchestrate responses to ischemic injury and critically influence neurovascular remodeling, axonal reorganization, and functional recovery. Emerging evidence indicates that inflammatory preconditioning can reprogram microglial responses to subsequent insults, yet the exact intracellular signaling pathways mediating this adaptive state remain incompletely defined. Here, we used a chemogenetic approach to selectively activate Gq signaling in microglia employing a microglia-specific DREADD mouse model. This strategy mimics Gq-coupled receptor activation in microglia in the absence of peripheral immune engagement. Pre-ischemic Gq activation significantly reduced infarct sizes at 24\u2009h after experimental stroke in female mice and at 7\u2009days in both sexes. Morphological analyses revealed that Gq-conditioned microglia exhibited increased structural complexity, adopting a highly ramified, spatially compact phenotype and higher CD68 expression, indicating increased phagocytic activity. Transcriptional profiling demonstrated that Gq activation primes autophagy-related defense pathways in microglia, resulting in upregulation of interferon-stimulated genes 7\u2009days after stroke in both sexes. Together, our findings identify Gq signaling as a key modulatory pathway capable of reprogramming microglial phenotype and enhancing stroke recovery. These results highlight the plasticity of microglial signaling networks and support targeted modulation of microglial Gq pathways.",

Previous studies have suggested circHECTD1's involvement in tumor processes, but its specific contributions and molecular pathways in CCA progression, particularly regarding autophagy regulation, remain unclear. Experimental data demonstrated significant upregulation of circHECTD1 in CCA cell lines, along with notable stability against RNase-mediated breakdown. From a functional perspective, increased circHECTD1 expression stimulated tumor cell growth, motility, invasive capacity, and autophagy processes, while triggering autophagosome formation. Mechanistically, circHECTD1 served as a molecular platform for the splicing factor SFPQ (proline- and glutamine-rich), facilitating SFPQ's binding to the ATG12 promoter regulatory region and enhancing the expression of ATG12 mRNA, resulting in increased transcriptional activity and enhanced mRNA durability, which in turn stimulated the autophagic process. When SFPQ was experimentally downregulated, this effect was diminished. Conversely, when autophagy was pharmacologically inhibited, the oncogenic effects mediated by circHECTD1 were effectively counteracted. These observations suggest that circHECTD1 plays a crucial role in the progression of CCA by forming a complex with SFPQ, which subsequently enhances both the transcription of ATG12 and the stability of ATG12 mRNA, thereby promoting autophagy and tumor progression.",

Herein, a dual-targeted nanotherapeutic platform (SC@GRT-COF-366) based on a covalent organic framework (COF-366) is reported for synergistic HCC treatment. This multifunctional system integrates chemotherapy, photodynamic therapy, autophagy regulation, and TME remodeling to synergistically inhibit tumor metastasis. Gal-D5HT-modified nanoparticles achieve enhanced HCC targeting via myeloperoxidase (MPO)-responsive aggregation in the inflammatory microenvironment and ASGPR-mediated uptake. Upon light irradiation, COF-366 generates singlet oxygen to induce tumor cell apoptosis and simultaneously enhances MPO expression and neutrophil infiltration, further amplifying MPO-triggered nanoparticle aggregation and establishing a self-amplifying retention-therapy cascade. Meanwhile, co-loaded sorafenib and chloroquine enable combined chemotherapy and autophagy inhibition, effectively overcoming drug resistance. In vivo results demonstrate significantly enhanced and prolonged tumor accumulation compared with single-targeted systems, resulting in a tumor growth inhibition rate of 93.5 \u00b1 1.02% in subcutaneous models and effective suppression of lung metastasis in orthotopic HCC models. Notably, treatment markedly reduces neutrophil extracellular traps (NETs) formation, indicating favorable remodeling of the tumor immune microenvironment. Collectively, this multifunctional COF-based nanoplatform integrates dual-targeted delivery, amplified tumor retention, and synergistic multimodal therapy, offering a promising strategy for advanced HCC treatment.",

Its disease spectrum can progress from simple hepatic steatosis to metabolic dysfunction-associated steatohepatitis (MASH), liver fibrosis, cirrhosis, and even hepatocellular carcinoma. Despite recent advancements in targeted pharmacological therapies for MASH, limitations persist regarding applicable populations and long-term benefits. Therefore, various lifestyle interventions, including dietary management and regular exercise, remain the cornerstone of MASLD management. AMP-activated protein kinase (AMPK), as an energy sensor, coordinates lipid synthesis, fatty acid oxidation, mitochondrial homeostasis, autophagy, and inflammatory responses under conditions of energy stress, thereby representing a key molecular hub connecting exercise, cold exposure, and the ameliorative effects on MASLD. Based on a narrative synthesis of mechanistic and translational evidence, this article summarizes the effects of exercise intervention, cold exposure, and their combination on AMPK-related pathways and further elucidates the potential mechanisms in terms of hepatic lipid metabolism, brown/beige adipose thermogenesis, skeletal muscle-adipose tissue-liver interorgan crosstalk, and mitochondrial quality control. Current evidence, particularly from animal and mechanistic studies, suggests that exercise and cold exposure may regulate MASLD-related metabolic abnormalities through the AMPK/ACC/SREBP1c, AMPK/SIRT1/PGC-1\u03b1 and AMPK/mTOR/TFEB pathways, as well as AMPK-related myokine/hepatokine networks. The combined intervention remains an emerging strategy; preclinical data indicate potential additive effects on energy expenditure and lipid clearance, but synergistic mechanisms, optimal temperature conditions, clinical safety, and long-term efficacy require further validation.",
"42568545": "ID: 42568545\nTitle: Circular RNAs in cervical cancer: from ceRNA networks to epitranscriptomic regulation, immune modulation, and metastatic reprogramming.\nAbstract: Cervical cancer progression is driven not only by persistent high-risk human papillomavirus infection but also by multilayered post-transcriptional regulatory networks that reshape tumor cell behavior and the tumor microenvironment. Among these regulators, circular RNAs (circRNAs) have emerged as pivotal modulators of oncogenic signaling. Initially characterized as competing endogenous RNAs (ceRNAs), circRNAs were shown to promote cervical cancer growth, invasion, and chemoresistance by derepressing key oncogenic targets. However, recent evidence expands this paradigm, revealing that circRNAs are subject to epitranscriptomic modification and function as dynamic scaffolds integrating RNA-binding proteins, translational machinery, inflammatory signaling, and metabolic pathways. In cervical cancer, m6A-dependent regulation and reader-mediated translational control enhance circRNA stability and amplify oncogenic outputs, linking RNA modification to metabolic reprogramming and hypoxia adaptation. Concurrently, circRNAs modulate inflammatory cascades such as IL6/JAK/STAT3 and NF-\u03baB, contributing to immune suppression and tumor microenvironment remodeling. These tumor-intrinsic and immune-extrinsic mechanisms converge on metastatic reprogramming, enabling lipid metabolic flexibility, lymphangiogenesis, autophagy activation, and therapeutic resistance. This review synthesizes current evidence to propose a unified regulatory landscape in which circRNAs function as central nodes connecting ceRNA circuits, epitranscriptomic modulation, immune signaling, and metabolic plasticity. Unlike previous reviews that primarily summarized circRNA-mediated ceRNA networks, canonical oncogenic pathways, or biomarker potential, this review adopts a systems-level perspective and critically integrates epitranscriptomic regulation, RNA-binding protein interactions, immune-inflammatory signaling, metabolic plasticity, and metastatic reprogramming. We further distinguish directly validated cervical cancer mechanisms from emerging or hypothetical regulatory layers, thereby providing a clearer conceptual framework for future mechanistic and translational studies.",
"42569254": "ID: 42569254\nTitle: Rewiring the mitochondrial NAD+-CoQ axis using metabolic nanomedicine for acute kidney injury therapy.\nAbstract: Acute kidney injury (AKI) represents a critical medical condition with high mortality and no effective pharmacotherapy. Mitochondrial dysfunction in proximal tubular epithelial cells (PTECs), characterized by NAD+ depletion, CoQ oxidation, and reactive oxygen species (ROS) overproduction, is a central driver of tubular damage and maladaptive repair. As central metabolic molecules, NAD+ and CoQ can effectively ameliorate acute kidney injury by alleviating mitochondrial oxidative stress. However, the bioavailability of NAD+ is limited by its short half-life, instability, and poor membrane permeability, whereas CoQ, despite being lipophilic, lacks specific mitochondrial targeting, preventing maximal therapeutic efficacy. Here, we report carrier-free NAD+/MitoQH2 nanoparticles (NM NPs) with ultrasmall size and ROS-responsive properties. NM NPs are designed to pass through the glomerular filtration barrier and preferentially accumulate in injured renal tubules, where they may replenish the NAD+ pool and provide a pre-reduced, mitochondria-targeted ubiquinol to support the CoQ axis under oxidative stress. Through renal accumulation and ROS-responsive release, NM NPs showed therapeutic efficacy in hypoxia/reoxygenation- and cisplatin-induced AKI models, as evidenced by reduced ROS accumulation, improved mitochondrial oxidative phosphorylation, enhanced autophagy, and attenuated ferroptosis. This work presents a metabolic nanomedicine strategy based on the co-assembly of bioactive molecules to modulate the mitochondrial NAD+-CoQ axis, providing a promising platform for AKI therapy and potentially other mitochondria-associated diseases.",
"42569303": "ID: 42569303\nTitle: The role of N-glycans and their processing in ER-to-lysosome-associated degradation of disease-causing mutant Neuroserpin.\nAbstract: Most proteins synthesized in the endoplasmic reticulum (ER) are covalently modified upon addition of pre-assembled oligosaccharides to side chains of asparagine (N) residues. Processing of N-linked oligosaccharides by ER-resident glucosidases, mannosidases and glucosyltransferases determines the fate of the associated polypeptides. Terminally glucose residues are removed from N-glycans to interrupt the engagement of ER-resident glucose-binding chaperones and promote secretion of native polypeptides. Mannose residues are removed to target terminally misfolded proteins for dislocation across the ER membrane and clearance by the cytoplasmic ubiquitin proteasome system (ER-associated degradation, ERAD). Recent evidence highlights the role of persistent N-glycan glucosylation as a signal that promotes ER lectins-driven segregation of misfolded proteins in ER subdomains that are eventually delivered to endolysosomal compartments for ER-to-Lysosome-Associated Degradation (ERLAD). Here we show that the polymerization-prone Portland variant of Neuroserpin (NS_PL) associated with familial encephalopathy with NS inclusion bodies (FENIB) is a client of the ERLAD machinery. Its lysosomal clearance relies on the LC3-dependent delivery branch of ERLAD involving the lectin chaperone Calnexin (CNX), the ERphagy receptor FAM134B and the SNARE protein Syntaxin17 (STX17), which is engaged upon persistent glucosylation of the NS_PL oligosaccharide linked at the asparagine residue at position 321.",

Previous studies have shown constitutive nuclear localization of the transcription factor TFEB and simultaneous hyperactivation of canonical MTORC1 signaling in the absence of FLCN. Here we assess the impact on autophagy under the situation of combined anabolic and catabolic activation. Using an established BHD patient-derived kidney cancer cell line, we confirmed that TFEB was permanently localized in the nucleus combined with an increase in canonical MTORC1 signaling, whereas bulk autophagy flux and LC3 lipidation were unaffected by FLCN status. However, we found that the autophagy receptor SQSTM1/p62 accumulated in enlarged puncta in the absence of FLCN. Finally, we recapitulate aberrant p62 accumulation in a Norwegian cohort of BHD kidney tumor samples. Our results demonstrate that FLCN loss is characterized by SQSTM1/p62 accumulation, although SQSTM1/p62 appears dispensable for anchorage-independent growth in cell models.",
"42569366": "ID: 42569366\nTitle: Immunosenescence shapes the tumor immune microenvironment and limits PD-1/PD-L1 blockade efficacy in older patients with cancer.\nAbstract: As the global population ages, immunosenescence is emerging as a critical determinant of cancer outcomes in older adults. Although programmed cell death protein 1/protein programmed death-ligand 1 (PD-1/PD-L1) blockade has significantly improved the treatment of multiple malignancies, its efficacy in older patients is highly heterogeneous, and the biological basis for this variability remains incompletely understood. Current evidence indicates that immunosenescence reshapes antitumour immunity through thymic involution, reduced T cell receptor diversity, chronic low-grade inflammation, and expansion of immunosuppressive cell populations, thereby impairing antigen presentation, weakening T cell activation and effector function, promoting terminal T cell exhaustion, and reinforcing suppressive tumour microenvironments. Together, these changes form an important mechanistic basis for the limited benefit of PD-1/PD-L1 blockade in older patients. Meanwhile, potentially targetable processes, including metabolic dysregulation, mitochondrial dysfunction, defective autophagy-mitophagy, redox imbalance, and gut microbiota dysbiosis, are increasingly recognized as modifiable contributors to age-associated resistance to immunotherapy. In this Review, we discuss how immunosenescence remodels antitumour immunity and constrains responses to PD-1/PD-L1 blockade in older patients, and we summarize potential strategies to improve immunotherapeutic efficacy in this population. These insights may inform future mechanistic studies, biomarker discovery, and the development of age-adapted therapeutic strategies.",
"42569412": "ID: 42569412\nTitle: Retinal ganglion cell autophagy: a housekeeper essential for neuronal homeostasis and survival.\nAbstract: Retinal ganglion cells (RGCs) are the sole projection neurons of the retina and the only direct link between retinal circuitry and the brain. Maintaining this lifelong connection requires constitutive autophagy to preserve organelle quality control and neuronal homeostasis. Although autophagy has been widely studied following ocular hypertension and optic nerve injury, its physiological role in healthy RGCs has remained unclear. We have recently revealed that basal autophagy is highly active in RGCs and that conditional deletion of Atg5 or Atg7 is sufficient to induce progressive RGC dysfunction, optic nerve degeneration, and neurodegeneration. Autophagy deficiency caused the accumulation of swollen mitochondria, distended endoplasmic reticulum, fragmented Golgi, synaptic vesicles, and incomplete autophagosomes accompanied by increased p62 and LC3B levels. These findings establish basal autophagy as an essential housekeeping mechanism that preserves organelle quality control and long-term RGC integrity.",

In this study, pilot proteomic screening of clinical gastric mucosal samples suggested a progressive decline in Sirtuin 1 abundance along the H. pylori-associated pathological cascade. Based on these findings, gastric epithelial cells-localizable oral nanomedicines (GLONs) are developed, whereby H. pylori eradication and reversal of precancerous intestinal metaplasia (IM) are simultaneously achieved via Sirtuin 1 restoration. GLONs are constructed by coating resveratrol, lactoferrin, and disulfide modified-fucoidan (DFu) co-assembled nanoparticles (RLF) with engineered mucin-overexpressing gastric epithelial cell membranes. The shell of GLONs resists gastric acid, enhances mucus penetration and epithelial cells uptake. After internalization, DFu undergoes oxidative destabilization in the H2O2-enriched infectious microenvironment induced by H. pylori, thereby triggering RLF core dissociation and subsequent component release. The resveratrol restored H. pylori infection-induced impairment of Sirtuin 1, thereby activating autophagy. Meanwhile, lactoferrin promoted antimicrobial peptide production and synergized with fucoidan-mediated enhancement of antigen presentation, ultimately enabling the clearance of both intracellular and extracellular H. pylori. In metaplastic gastric cells, Sirtuin 1 repairs damaged DNA, and inhibits malignant proliferation. In mouse models, under the tested 7-day regimen, GLONs produced greater reductions in gastric H. pylori burden and more pronounced improvements in IM-related phenotypes than the abbreviated triple-therapy. GLONs represent an innovative and highly efficient therapeutic platform for H. pylori infection and its complications.",

This study aims to explore the role of the novel autophagy receptor CCDC50 in cerebral IRI and its molecular mechanism. Cellular oxygen-glucose deprivation/reoxygenation model and middle cerebral artery occlusion (MCAO) animal model were adopted in this study. Quantitative real-time polymerase chain reaction, Western blot, immunofluorescence, and immunohistochemistry assays were applied to detect the expression and subcellular localization of key molecules including LL37, CCDC50, STING, IRF3, Rspondin3, and autophagy-related proteins. Co-immunoprecipitation was performed to explore protein-protein interactions. Enzyme-linked immunosorbent assay and flow cytometry were utilized to determine the levels of inflammatory cytokines and the M1/M2 polarization phenotypes of microglia. Additionally, 2,3,5-triphenyltetrazolium chloride staining was carried out to measure cerebral infarct volume. Results revealed that LL37 directly bound to CCDC50 and facilitated its ubiquitination and degradation. This process disrupted the interaction between CCDC50 and STING, thereby triggering the activation of the STING/IRF3 signaling pathway. Conversely, CCDC50 enhanced autophagy and restrained the STING/IRF3 pathway activation. It further drove microglial polarization toward the anti-inflammatory M2 phenotype, blocked pro-inflammatory M1 phenotype transition and inflammatory cytokine secretion, and ultimately alleviated neuronal damage. The above in vitro molecular mechanisms were also validated in the MCAO model. By enhancing autophagy, CCDC50 suppresses the STING/IRF3 pathway and facilitates M2 polarization of microglia, ultimately mitigating cerebral ischemia-reperfusion injury. In contrast, LL37 counteracts this protective effect by mediating CCDC50 degradation. This study identifies novel potential therapeutic targets for ischemic stroke.",
"42570241": "ID: 42570241\nTitle: Diurnal regulation of Acyl-CoA synthetase 3 (ACSF3) governs rhythmic mitochondrial lysine-malonylation and daily hepatic metabolism.\nAbstract: Hepatic daily rhythms are coordinated by feeding and the molecular circadian clock, ensuring metabolic homeostasis. Disrupted feeding schedules promote circadian misalignment and metabolic diseases but the underlying mechanisms remain scarce. Post-translational modifications have emerged as key regulators of circadian metabolic outputs. Here, we show that the mitochondrial enzyme Acyl-CoA synthetase family member 3 (ACSF3) oscillates in phase with different feeding schedules to drive rhythmic lysine-malonylation and coordinate daily hepatic metabolism. Hepatic Acsf3 knockdown drastically affected lysine-malonylation rhythms, decreased fasting glycemia, insulin sensitivity, and AKT phosphorylation, indicative of perturbed glucose homeostasis. Concomitantly, Acsf3 knockdown shifted lipid oxidation from mitochondria to peroxisomes, enhanced lipogenesis and triglyceride synthesis, while increasing diurnal autophagy. Multi-omics profiling uncovered specific lysine-malonylation targets in glycolysis, the tricarboxylic acid (TCA) cycle, fatty-acid oxidation and autophagy. Our findings uncover hepatic ACSF3 as a pivotal molecular nexus that integrates feeding time with dynamic protein lysine-malonylation and orchestrates the diurnal rhythm of liver metabolism.",

This study investigates the pathological mechanisms of HCQ/CQ- and colchicine-induced myopathies through integrated clinical, histopathological, ultrastructural, and proteomic analyses. Nine patients with clinicopathologically defined toxic myopathy (HCQ/CQ, n\u2009=\u20094; colchicine, n\u2009=\u20095) were included. Muscle biopsies were analyzed using histoenzymology, immunohistochemistry for autophagic and immune markers, electron microscopy, and proteomic profiling in selected cases. Clinically, both groups presented with proximal muscle weakness and myalgia after variable drug exposure. Histology revealed rimmed and non-rimmed vacuoles, especially in HCQ/CQ cases, and myofibrillar disorganization; the latter predominated in colchicine-treated patients. Electron microscopy confirmed myofibrillar disruption in colchicine-treated patients and autophagosomes with curvilinear bodies in HCQ/CQ cases. Immunohistochemistry showed MHC-I upregulation, heterogeneous C5b-9 deposition, and accumulation of LC3 and p62, with evidence of endoplasmic reticulum stress and transcriptional dysregulation by GRP170 overexpression and cytoplasmic MeCP2 redistribution. Proteomic analysis revealed a shared molecular signature involving immune activation, extracellular matrix remodeling, cytoskeletal stress, mitochondrial dysfunction, and dysregulation of the autophagy-lysosome pathway. Overall, HCQ/CQ- and colchicine-induced myopathies converge on common mechanisms of autophagic impairment, immune activation, and disrupted muscle homeostasis.",

Metformin, a widely prescribed antihyperglycemic agent, not only lowers blood glucose levels but also modulates multiple intracellular signaling pathways, thereby exerting pleiotropic effects. The present study aimed to evaluate the cardioprotective effects of metformin and elucidate its underlying molecular mechanisms in myocardial ischemia-reperfusion injury. Accordingly, we established in vivo diabetic models and in vitro hyperglycemic conditions to assess the effects of metformin on myocardial tissue in diabetes. The results demonstrated that metformin treatment significantly ameliorated cardiac dysfunction and attenuated myocardial morphological abnormalities in diabetic rats subjected to ischemia-reperfusion, and concurrently improved cardiomyocyte viability under hyperglycemic conditions. Moreover, metformin enhanced autophagy, promoted mitophagic activity, and restored mitochondrial homeostasis-effects that were further validated using compound C in cultured cardiomyocytes under hyperglycemic conditions. Collectively, these findings indicate that metformin confers cardioprotection against myocardial ischemia-reperfusion injury (MIRI) through activation of AMP-activated protein kinase (AMPK) and its downstream signaling cascades, thereby regulating mitophagic processes.",

Maternal exposure to DCHP may adversely affect offspring health. However, its effects on early embryonic development and female offspring, and the underlying mechanisms affecting offspring reproductive function remain unclear. In this study, using an in vitro mouse embryo culture system and a maternal gestational exposure model, we found that DCHP exposure induced DNA damage, disrupted spindle morphology and chromosome alignment during the first cleavage of early mouse embryos, accompanied by reduced blastocyst formation. Transcriptomic analysis of ovarian tissues from high-dose DCHP-exposed offspring revealed enrichment of pathways related to mitochondrial dysfunction and apoptosis. Functional validation showed that DCHP exposure was associated with oxidative stress and mitochondrial dysfunction, characterized by increased reactive oxygen species levels and reduced mitochondrial membrane potential, along with increased autophagy and apoptosis. Rescue assays using Mito-TEMPO and Mdivi-1 alleviated DCHP-induced mitochondrial damage and restored blastocyst developmental competence, suggesting that mitochondrial dysfunction and subsequent mitophagy activation act as key upstream events in DCHP-induced embryonic damage. Moreover, gestational exposure to the highest dose of DCHP significantly increased ovarian apoptosis and reduced oocyte maturation in female offspring. Collectively, these findings suggest that gestational high-dose DCHP exposure is linked to reduced reproductive potential and ovarian dysfunction in female offspring through oxidative stress-mediated mitophagy, providing new insights into female reproductive dysfunction associated with environmental phthalates.",

We aim to develop molecular strategies that selectively dampen TLR4-driven inflammation without eliminating host defense. Here, we demonstrate that CRISPR-Cas9-mediated dual-site editing of the TLR4 gene, by introducing specific disruptions in both the extracellular domain (ECD) and the intracellular Toll/IL-1 receptor (TIR) domain, can generate a partially uncoupled signaling phenotype that selectively attenuates acute inflammation while preserving baseline stress-adaptive mechanisms. By combining whole-genome and amplicon-based next-generation sequencing, RNA-Seq, molecular dynamics simulations, transmission electron microscopy (TEM), GSEA, and functional reporter assays, we show that targeted mutations near the LPS-binding interface within the LRR modules of the ECD (M209I, V254I, E593D) and within the CD loop of the TIR domain (R761H) reduce ligand binding-pocket volume by ~17% (688.19\u00c53 vs. 825.41\u00c53) within TLR4 loci, leading to partial signal propagation and altered LPS trafficking to lysosomal compartments through autophagosome sequestration. Immunofluorescence profiling revealed broad attenuation of TLR-signaling networks, MyD88/TRAF6 recruitment, and downstream NF\u03baB-MAPK-PI3K-AKT-JAK-STAT-mTOR cascades alongside decreased CD14 expression, suppressed ROS generation, and diminished caspase-3 activity. While complementary NF\u03baB and LC3-HiBiT reporter assays confirmed interrupted LPS-induced inflammatory transcription and conventional autophagic flux activation, TFEB reporters revealed that edited macrophages remain highly sensitive and responsive to direct metabolic mTOR-dependent metabolic inhibition via Rapamycin. Collectively, our findings establish TLR4 as a central molecular switch and suggest that CRISPR-Cas9-mediated dual-site editing reprograms macrophages into repair-oriented, adaptive phenotype with implications for therapeutic strategies targeting inflammation, sepsis, and autophagy-driven tissue protection.",

This study aimed to identify non-chelating polyphenols capable of mitigating zinc toxicity and to elucidate their protective mechanisms, with emphasis on ferroptosis inhibition. Network toxicology predicted ferroptosis as a central mechanism in zinc-induced intestinal injury, which was confirmed in intestinal epithelial cells where zinc overload specifically induced ferroptosis without activating apoptosis, necroptosis, or autophagy. From multiple polyphenols, fisetin (FIS) was identified as a non-chelating candidate that alleviated zinc-induced cytotoxicity, preserved tight junction proteins, and activated the Nrf2-GPX4 axis to inhibit ferroptosis in vitro. In zinc-overloaded weaned piglets, FIS supplementation maintained the growth-promoting effects of high-dose zinc while ameliorating intestinal damage. FIS also attenuated oxidative stress, alleviated inflammation, and inhibited ferroptosis in the jejunum. Furthermore, FIS remodeled the gut microbiota, enriching beneficial taxa Romboutsia (positively correlated with growth performance) and Clostridium_sensu_stricto_1 (positively correlated with the p-Nrf2/Nrf2 ratio), while suppressing the zinc-enriched Anaerovibrio (negatively correlated with GPX4 protein expression). FIS also shifted microbial metabolic pathways toward amino acid and terpenoid metabolism, potentially contributing to the observed ferroptosis defense. FIS alleviates high-dose ZnO-induced intestinal injury in weaned piglets through dual modulation, activating the Nrf2-GPX4 axis to inhibit ferroptosis and remodeling the gut microbiota to reinforce this defense. By preserving the growth benefits of zinc while mitigating its toxicity, FIS represents a promising nutritional strategy for sustainable swine production.",

A fine-grained climatic resolution is indispensable to anticipate species-specific habitat redistributions for effective conservation planning. Focusing on 20 giant panda forage bamboo (GPFB) species across 5 genera that constitute the bulk of the giant panda's (Ailuropoda melanoleuca) diet, we developed a \"species-distribution modelling based on climate-delta downscaling\" framework to project potential geographic shifts at a 30\u2009m resolution across the 21st century under SSP1-2.6, SSP2-4.5, and SSP5-8.5 scenarios. We found three primary results: (1) while the total climatically suitable area for GPFB expands under future scenarios, localized species richness within these habitats declines. (2) A mid-elevation bamboo buffer zone (3000-4500\u2009m) emerges as a critical thermal sanctuary where 7 out of 20 species expand under an unlimited dispersal assumption. However, incorporating a realistic biological dispersal constraint (10\u2009m/year) severely truncates this elevational advantage, precipitating an overall habitat contraction for 11 species and reducing accessible refugia to merely 44%-65% of their theoretical potential. At localized scales, range shifts exhibit non-monotonic trajectories and multidirectional movements rather than uniform upslope or northward migrations. (3) Integrating baseline and 12 future projections, we delineated stable macroclimate refugia governed by steep topographies, high hydrological availability, long-term annual precipitation stability, and distinct seasonal environmental variations. 78.6% to 89.2% of the bamboo climate refuges overlap with the current (in 2025) forest distribution. Alarmingly, only 38.46%-44.11% of these crucial refugia fall within the current boundaries of the Giant Panda National Park, leaving extensive, contiguous refugia in the Liangshan mountain region largely unprotected. We recommend the establishment of a climate-buffered conservation network that integrates extra-park bamboo resources into unified spatial planning and deploys targeted connectivity corridors to mitigate dispersal bottlenecks. This 30\u2009m workflow provides a high-fidelity, transferable technical template for climate-adaptation forecasting of threatened montane specialized diet species globally.",

Iridium oxide, the preferred anode catalyst in PEMEL, offers exceptional stability but is produced only as a by-product of platinum mining, with annual output around 7.5 tons. This study estimates future iridium demand for PEMEL under various global deployment scenarios and technological advances. Results show that meeting net zero targets will require both significant improvements in catalyst efficiency and access to roughly 30% of global iridium production annually. Supply shortages could arise as early as 2030, earlier than previously anticipated. The analysis also reveals that long-term iridium needs beyond 2040 are significantly underestimated. These findings underscore the urgent need for innovation in material efficiency and recycling, and the importance of integrating resource constraints into energy policy and technology planning to ensure a sustainable hydrogen transition.

The OvertureTi Knee Resurfacing System is designed to treat focal defects while preserving native bone, cartilage, and soft tissue. Focalplasty is indicated in patients with compartmentalized cartilage lesions, preserved ligamentous stability, and meniscal integrity or repairable tears. Appropriate alignment, joint space preservation, and minimal osteophyte formation are required. The procedure began with arthroscopic repair of the medial meniscus root using a transtibial pull-out technique. Following this, an open approach was performed to expose the medial femoral condyle. The chondral defect was sized, and appropriate instrumentation was used to prepare the site. Cartilage scoring and sequential reaming were performed to achieve the desired depth and contour. Trial components were confirmed to fit and position, after which peg holes were drilled and filled with bone cement. Finally, the oblong OvertureTi femoral implant was seated flush with the surrounding cartilage surface, and standard wound closure was completed. At 2 weeks, radiographs confirmed proper implant positioning. Long-term outcomes of the Overture prosthesis are not yet available. However, studies on similar implants, such as the HemiCAP, have reported improved function and survivorship at mid- to long-term follow-up. The Overture prosthesis offers advantages over arthroplasty and biologic resurfacing, including lower cost, off-the-shelf availability, preservation of native tissues, and bone conservation for future arthroplasty.

Recent evidence indicates that protein homeostasis (proteostasis) functions as a crucial molecular link connecting tumor progression, therapeutic resistance, cardiac remodeling, and treatment-related cardiotoxicity. Proteostasis, which encompasses the cellular processes of protein synthesis, folding, quality control, and degradation, dictates tissue adaptation to chronic stress. Notably, the adaptive mechanisms that allow tumor cells to endure proteotoxic stress and resist therapy are often vital for maintaining cardiac structure and function. Thus, tumor control and cardiovascular injury may be divergent outcomes of a common stress-response framework. In this review, we propose proteostasis as a comprehensive framework for understanding the cancer-cardiovascular interface. We analyze how the ubiquitin-proteasome system, autophagy-lysosome pathway, endoplasmic reticulum stress-induced unfolded protein response signaling, and molecular chaperone networks are differentially reconfigured in cancer and cardiac tissues, influencing tumor survival, therapeutic susceptibility, and cardiovascular dysfunction. Additionally, we explore the translational implications of proteostasis dysregulation, including mechanisms of anticancer therapy-induced cardiotoxicity, emerging biomarkers, cardioprotective strategies, and opportunities for precision cardio-oncology. By conceptualizing efficacy and toxicity as interconnected outcomes of shared proteostasis biology, this review establishes a foundation for developing therapies that optimize cancer control while safeguarding cardiovascular health.",

The noise is space-dependent and statistically translation-invariant. We show that, for small forcing, solitons remain close to the family of traveling waves in a weighted Sobolev norm, with high probability. We study the effective dynamics of the soliton amplitude and position via their variational phase, for which we derive explicit modulation equations.

The present study, conducted in Taiwan, aimed to identify pre-fieldwork core competencies essential for preparing occupational therapy undergraduates for mental health fieldwork, with a focus on professional readiness and resilience. A two-round Delphi survey was conducted with MHOT fieldwork instructors across Taiwan. Round 1 included 14 experts (10 completed) and generated preliminary items through qualitative analysis. Round 2 involved 20 experts (16 completed) who rated item appropriateness and agreement. Consensus was evaluated using descriptive statistics and predefined thresholds. Expert consensus confirmed 15 pre-fieldwork core competencies; each meeting established subjective criteria (median, interquartile range, standard deviation). Content validity ratios exceeded 0.49, averaging 0.76. The Percentage of Positive Ratings ranged from 52.94% to 94.12%, averaging 82.75%, surpassing the 70% threshold. Kendall's W showed moderate agreement for definition appropriateness (0.494, p\u2009<\u20090.000) and overall agreement (0.34, p\u2009<\u20090.000). Metrics for convergence, consensus and stability (0.34-0.85) confirmed strong expert alignment. The framework comprises 11 core and 4 adaptive competencies, organised into 5 domains, and provides a practice-oriented blueprint for early clinical preparation in VUCA-challenged mental health settings.",

This study employed a comprehensive in silico pipeline to identify antimicrobial peptides (AMPs) targeting the essential DNA replication initiator protein DnaA. A total of 28,361 peptide sequences were collected from publicly available AMP databases and sequentially filtered based on peptide length, net charge, GRAVY score, instability index, antimicrobial activity, toxicity, hemolytic potential, aggregation propensity, sequence similarity and favorable amphipathic properties. Four peptides satisfied all selection criteria and were subjected to structural prediction, membrane-binding analysis, protein-DNA docking, protein-peptide docking, and Normal Mode Analysis. Protein-DNA docking identified the functional DNA-binding residues of DnaA, while peptide docking demonstrated that all four peptides interacted within this region. Peptide 3 exhibited the strongest predicted interaction, with a binding energy of -61.8\u00b15.1, a buried surface area of 1151.7\u00b130.8 \u00c52, and seven hydrogen bonds with key DnaA residues. Normal Mode Analysis further supported the structural stability of the peptide-protein complexes. These findings identify four promising AMP candidates targeting DnaA and provide a computational framework for peptide prioritization against multidrug-resistant K. pneumoniae. However, the proposed interactions remain computational predictions and require experimental validation.",

Social determinants of health, including material needs security and food security, play a critical role in diabetes management, yet their interrelated effects remain underexplored. This study aims to examine the relationship between material needs security and food security among Lebanese adults with T2DM of low socioeconomic status. A cross-sectional study was conducted on 299 Lebanese adults with T2DM recruited from three primary health care centers. Participants completed validated questionnaires assessing sociodemographic factors and food security. Material needs security score was computed based on ownership and access for certain house utilities, as well as car ownership. Unadjusted and adjusted logistic regression models were conducted to evaluate associations between material needs security and food security. Higher material needs security was significantly associated with food security in both the unadjusted and adjusted regression models (odds ratio = 1.26, 95% confidence interval: 1.06-1.49, p = 0.007). Food and material needs insecurities were more prevalent among females and individuals with lower income, lower education, and lack of health insurance. This study highlights the strong association between material needs security and food security in Lebanese adults with T2DM, emphasizing the importance of addressing social determinants in diabetes management. Policies targeting financial stability, food security interventions, and access to health care are essential to improving health outcomes in vulnerable populations.",

Although both early and delayed implant placement protocols are widely used, evidence regarding their effects on implant stability and masticatory function is limited. This study aimed to compare early and delayed dental implant placements in terms of implant stability and bite force. Materials and methods This prospective observational study was conducted at the Department of Prosthodontics, K. M. Shah Dental College and Hospital, Sumandeep Vidyapeeth (Deemed to be University), Vadodara, Gujarat, India. Sixty patients were categorized into two groups of 30 participants in each group. The early implant group received implants four to eight weeks after tooth extraction, whereas the delayed implant group underwent implant placement after a minimum healing period of six months. Implant stability was assessed using resonance frequency analysis (RFA) and expressed as implant stability quotient (ISQ) values. Functional rehabilitation was evaluated by measuring the bite force using a digital occlusal force analyzer. Assessments were performed at baseline and six months after prosthetic loading. Statistical analyses were conducted using paired and independent t-tests, with statistical significance set at p < 0.05. Results Both groups demonstrated significant improvements in implant stability and bite force over the six-month follow-up period (p = 0.001). In the early implant group, the mean ISQ values increased from 62.4 \u00b1 4.8 to 74.6 \u00b1 3.9, whereas the delayed implant group showed an increase from 58.7 \u00b1 5.2 to 71.2 \u00b1 4.6. The bite force increased from 128.4 \u00b1 22.6 N to 218.3 \u00b1 31.4 N in the early implant group and from 134.7 \u00b1 25.1 N to 204.6 \u00b1 28.9 N in the delayed implant group. The early implant group demonstrated significantly higher implant stability at baseline and six months (p < 0.05). Although the bite force values at individual time points were comparable between the groups, the increase in bite force over time was significantly greater in the early implant group (p = 0.006). Conclusions Both early and delayed implant placement protocols achieved successful osseointegration and functional rehabilitation in the present study. However, early implant placement demonstrated superior implant stability and greater improvement in bite force, suggesting that it may provide favorable clinical outcomes when appropriate case selection and treatment planning are performed.",

En masse retraction and two-step retraction are widely used space-closure mechanics; however, differences in treatment efficiency, anchorage preservation, and arch dimensional changes remain. This study aimed to compare the outcomes of en masse retraction and two-step retraction mechanics in patients with Class I bimaxillary protrusion undergoing extraction-based orthodontic treatment. This retrospective comparative study evaluated the completed orthodontic records of 100 patients with Class I bimaxillary protrusion who were treated between 2016 and 2021. The patients were classified into two groups: en masse retraction (n = 50) and two-step retraction (n = 50). Measurements were obtained from the pretreatment and post-treatment study models and treatment records. The variables assessed were maxillary incisor retraction, anchorage loss, treatment duration, retraction rate, extraction space closure efficiency, residual extraction space, and transverse arch dimensional changes. Data were analyzed using an independent samples t-test, a chi-square test, and a Mann-Whitney U test. Statistical significance was set at p < 0.05. Both treatment modalities achieved comparable maxillary incisor (6.84 \u00b1 1.12 mm vs. 6.52 \u00b1 1.08 mm; p = 0.129). The en masse retraction group demonstrated significantly greater anchorage loss, with a first molar mesial drift of 2.18 \u00b1 0.76 mm compared with 1.43 \u00b1 0.61 mm in the two-step retraction group (p < 0.001). Space closure duration was significantly shorter in the en masse group (8.6 \u00b1 1.8 months) than in the two-step group (11.4 \u00b1 2.3 months) (p < 0.001). Extraction space closure efficiency was higher in the en masse group (96.90 \u00b1 2.80%) than in the two-step group (95.40 \u00b1 3.20%) (p = 0.011). Significant reductions in intercanine, intermolar, and interpremolar widths were observed in the en masse group compared with the two-step group (p < 0.001). Both retraction mechanics were effective in achieving anterior tooth movement. En masse retraction provided faster space closure and greater treatment efficiency but was associated with increased anchorage loss and greater transverse arch constriction. Two-step retraction demonstrated superior anchorage preservation and transverse dimension stability.",

In practice they drift over time, and aggregation that ignores this lets unstable clients degrade the global model. This article describes JS-Drift, a reproducible, model-agnostic procedure that quantifies per-client temporal drift using Jensen-Shannon (JS) divergence between a client's label distribution in consecutive communication rounds, converts that divergence into a stability weight via a single sensitivity parameter \u03b3, and folds the weight into the aggregation step.

Bacteriophage therapy offers a promising alternative to conventional antibiotics, though effective delivery systems remain critical for clinical translation. This study reports the isolation, genomic characterization, and alginate hydrogel-based formulation of a lytic bacteriophage, KA_SGEB_01, targeting multidrug-resistant K. aerogenes. The phage was isolated from hospital sewage using multidrug-resistant K. aerogenes as a host. Comprehensive characterizations included plaque morphology and host range determination, multiplicity of infection (MOI) optimization, one-step growth kinetics, antibiofilm activity assays, and environmental stability testing. Complete genome sequencing and annotation were performed. Phage-loaded alginate hydrogels were developed and evaluated for release kinetics, long-term viability, and antibiofilm efficacy. KA_SGEB_01 produced clear plaques (1 \u00b1 0.1 mm) with halos indicative of depolymerase activity and exhibited strict host specificity. The optimal MOI was 0.01 with a 15-minute latent period and the phage remained stable between -20 \u00b0C and 50 \u00b0C; and across a pH range 6-9. Biofilm assays demonstrated around 60% Crystal-Violet-stained biomass reduction as well as significant biofilm disruption visualized by Scanning Electron Microscopy. Whole-genome sequencing revealed a 175,095 bp double-stranded DNA genome encoding 289 predicted coding sequences, classified within the family Straboviridae, genus Slopekvirus, and lacking any virulence or AMR genes. Encapsulation in alginate hydrogels preserved viability (>10\u2079 PFU/mL) for 14 days and enabled sustained release (\u223c 67% at 72 h), resulting in significant biofilm biomass inhibition. Collectively, KA_SGEB_01-loaded alginate hydrogels represent a promising platform for treating multidrug-resistant K. aerogenes in wound and device-associated infections caused by the bacterium.",

Focusing on drying, a key quality-related subquality, we examined whether wine-saliva aggregates can contribute to lubrication stability rather than only increasing friction. Red wines spanning non-drying to highly drying profiles were mixed 1:1 with unstimulated human saliva. Film thickness and friction were measured under controlled, oral-inspired sliding conditions, and mixtures were centrifuged to obtain soluble (supernatant) and insoluble (pellet) fractions characterized for colloidal stability, interfacial wetting, turbidity, viscosity, and macromolecular composition. Lower drying was associated with thicker films and lower friction, with more stable, entrainable supernatants showing more negative zeta potential, smaller colloids, higher suspended turbidity, and greater polysaccharide support. Overall, the results support a supernatant-centric view in which aggregate functionality and morphology relate to drying subquality, suggesting routes to soften mouthfeel without necessarily reducing phenolics.",
"42571360": "ID: 42571360\nTitle: A UAV-based semi-supervised segmentation framework for pine wilt disease via vegetation Index-RGB synergy.\nAbstract: Pine wilt disease (PWD), caused by the pine wood nematode (Bursaphelenchus xylophilus), continues to threaten forest ecological security. Unmanned aerial vehicle (UAV) remote sensing makes large-scale screening feasible, but accurate canopy segmentation remains difficult in practice. The main obstacles are threefold: (i) canopy appearance changes noticeably from early to late infection stages, which can cause model representations to drift toward later-stage symptoms and weaken subtle early-stage cues; (ii) dense pixel-wise annotation is costly, making semi-supervised learning dependent on imperfect pseudo-labels; and (iii) forest backgrounds are cluttered and often visually similar to diseased regions, limiting the discriminative ability of RGB appearance alone. To address these three practical difficulties, we build a standardized UAV canopy dataset for PWD and develop a lightweight multimodal segmentation framework. The method combines three components. First, Nested-Tempo Memory Consolidation (NTMC) is designed as a stage-aware extension of EMA-based teacher-student learning. It maintains nested fast/medium/slow temporal trajectories to retain stage-specific knowledge while improving cross-stage stability during Early-Middle-Late sequential training. Second, Drift-Compensated Consistency Regularization (DCCR) integrates reliability calibration into semi-supervised consistency learning, so that unlabeled samples contribute training signals mainly when they are sufficiently reliable, reducing error accumulation from noisy pseudo-supervision. Third, Vegetation-index-conditioned Cross-Modal Attention (VCCA) uses vegetation indices-Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI)-as physiological cues to modulate visual features, thereby reducing the dependence on RGB appearance and improving feature discrimination under texture-similar forest backgrounds. Experiments on one in-house dataset and three external datasets show consistent improvements in mean intersection over union (mIoU), F1-score, and Matthews correlation coefficient (MCC). With all components enabled, the framework improves mIoU from 0.6015 to 0.6829 over the baseline and produces cleaner disease boundaries with fewer background false alarms, demonstrating its potential for practical UAV-based forest disease monitoring.",

There are many causes of anterior crossbite, and the presence of supernumerary tooth/teeth is one of them. Early interceptive intervention is essential to avoid the need for more complex orthodontic treatment later. This case report describes the management of a 10-year-old child who presented with anterior crossbite involving Teeth 21 and 31, leading to gingival recession of Tooth 31. The crossbite malocclusion was associated with a supernumerary tooth in the upper incisor region. Extraction of the supernumerary tooth was performed, and correction of the anterior crossbite was commenced with a 2 \u00d7 4 appliance. Adequate stability with a positive overjet was observed at the 6-month review.

To evaluate long-term skeletal, dentoalveolar, and soft tissue stability following mandibular advancement with BSSO and rigid fixation. A retrospective cohort study was conducted in 32 patients undergoing mandibular advancement with BSSO and rigid fixation. Cephalometric measurements were obtained at four time points: preoperative, immediate postoperative, 12 months, and long-term follow-up (>3 years). Changes were analyzed using the Wilcoxon signed-rank test. The mean mandibular advancement was 5.42\u202f\u00b1\u202f1.71\u202fmm. Immediately after surgery, significant skeletal correction was achieved, with increased SNB and decreased ANB (both p\u202f<\u202f0.001), accompanied by significant improvements in occlusal and soft tissue profile measurements. Most skeletal and occlusal parameters remained stable during the first postoperative year and throughout long-term follow-up, with no statistically significant changes observed between one year and the final evaluation.

Lycopene, an antioxidant, is limited by poor bioavailability, whereas Wilms tumor 1-associating protein (WTAP), a core m6A methyltransferase, has no specific inhibitors. Herein, we fabricated cartilage-targeted HPcLW nanoparticles (\u223c250\u202fnm) via electrostatic self-assembly of human serum albumin (HSA) and poly-L-lysine (PLL) with collagen II-binding peptide, co-loaded with lycopene and WTAP siRNA. The targeting modification extended joint fluorescence retention to 10 days after intra-articular injection with good serum stability and biosafety. In aged mice and medial meniscus (DMM)-induced OA mouse models, intra-articular HPcLW attenuated cartilage degeneration, restored COL2 expression, and suppressed MMP13 levels. Mechanistically, WTAP siRNA suppressed m6A modification to downregulate PAI-1 expression, while lycopene scavenged ROS and protected siRNA integrity, cooperatively disrupting the WTAP/PAI-1 axis and alleviating mitochondrial dysfunction.

However, insufficient tumor accumulation and limited immunological activation remain major obstacles restricting their therapeutic efficacy in solid tumors. Herein, we report a macrophage-assisted delivery strategy based on hyaluronic acid-engineered copper sulfide nanoparticles (HA@CuS NPs) for enhanced photothermal-immunotherapy against osteosarcoma. In this system, adoptively transferred RAW264.7 macrophages were intravenously administered to increase macrophage enrichment within the osteosarcoma microenvironment, while HA@CuS NPs were rationally designed to target both tumor cells and tumor-associated macrophages through HA-mediated cellular recognition. The HA-coated CuS nanoparticles displayed good colloidal stability, efficient near-infrared photothermal conversion, and enhanced cellular uptake by osteosarcoma cells and macrophages. Importantly, macrophages acted as cellular reservoirs for CuS nanoparticles, promoting tumor accumulation and improving intratumoral photothermal distribution. Under 808-nm laser irradiation, the combined macrophage/HA@CuS treatment produced stronger tumor heating and more effective osteosarcoma ablation than HA@CuS nanoparticles alone. Beyond direct photothermal killing, HA@CuS nanoparticles also remodeled the tumor immune microenvironment by promoting M1-like polarization of tumor-associated macrophages, increasing IL-12p40 secretion, reducing IL-10 levels, and enhancing cytotoxic T lymphocyte infiltration. These immune-regulatory effects further amplified the antitumor response induced by photothermal therapy. Collectively, this study demonstrates that HA-engineered copper sulfide nanoparticles can function not only as metal sulfide photothermal agents but also as immunomodulatory nanomaterials. The integration of macrophage-assisted tumor delivery with CuS-based photothermal therapy provides a promising strategy for improving the therapeutic efficacy of metal-based nanomedicine against osteosarcoma.",

This study investigated stage-specific brain network patterns in normal-hearing tinnitus patients using electroencephalography (EEG) microstate and dynamic functional network (DFN) analyses. Resting-state EEG was recorded from 45 participants (15 acute tinnitus, <6 months; 15 chronic tinnitus, \u22656 months; and 15 healthy controls). Results showed that acute tinnitus involved enhanced salience network engagement and reduced central executive network participation, with transitions skewed toward salience processing. Chronic tinnitus exhibited normalized transitions but increased global explained variance, indicating greater network stability. DFN analysis revealed elevated \u03b3-band efficiency in the executive network during acute tinnitus, while chronic tinnitus showed increased low-frequency (\u03b4/\u03b2) efficiency in executive and auditory networks. These findings demonstrate distinct neurophysiological profiles across tinnitus stages-acute salience-executive imbalance with aberrant high-frequency synchrony versus chronic compensatory rebalancing through low-frequency adaptation-providing a framework for stage-specific biomarker identification.",

Recent researchers have explored various techniques to understand this behaviour of LLMs, including uncertainty measures, semantic consistency, robustness, and prompt sensitivity. However, the research lacks a reproducible methodology that combines semantic and structural parameters. Thus, the proposed consistency evaluation protocol focuses on evaluating the consistency of LLM responses through repeated prompting, extracting relevant features, and analysing structural and semantic stability through consistency scores. The framework was evaluated using Mistral-7B-Instruct-v0.2 on a set of 20 input texts. For each input text, five independent responses were generated. For each of the generated responses, semantic consistency is determined through embedding-based text representations. In addition, the structural variation is studied through fluctuations in sentence length, word usage, and lexical diversity. Lastly, these measurements are combined to form the Composite Consistency Score (CCS). Further, the validation tests are performed, containing temperature sensitivity, prompt sensitivity, and metric validations reflecting reliable and reproducible consistency evaluations.",

Response variability due to exercise may reflect underlying biological heterogeneity in PCOS phenotypes. We explored changes in non-invasive PCOS biomarkers following a 16-week Interval Nordic Walking (INW) to identify phenotype-related response differences. A total of 7500 women's data were obtained from the Yazd Reproductive Sciences and Amir al M\u00f3menin Hospital (2019-2024). PCOS was diagnosed according to the Rotterdam criteria. XGBoost feature selection was implemented to choose 17 key predictors. Multiple ML classifiers were evaluated, and model interpretability was achieved using SHAP values. 80 women with different PCOS phenotypes completed a 16-week INW intervention. PCA was applied to reduce the features to 75% variance. Then clustering algorithms (K-means, GMM, Hierarchical, Spectral, DBSCAN) were evaluated using Silhouette scores, Calinski-Harabasz indices, and bootstrap resampling (Jaccard index). XGBoost and SHAP analysis confirmed AMH, FSH, and Anti-TPO as the most influential predictors of PCOS, while metabolic indices like HbA1c, BMI, and lipid profiles exhibited moderate but clinically relevant effects. The spectral model provided better separation among evaluated algorithms; however, overall cluster separation remained modest. It suggested two exploratory data-driven response patterns, termed high-response (more frequently observed phenotypes one and two), which demonstrated greater observed reductions in testosterone and DHEA-s along with improvements in HDL and total cholesterol following the intervention. Low-response (more frequently observed phenotypes three and four) showed relatively minimal response to INW. Based on mean Jaccard index\u202f=\u202f0.45, cluster stability was moderate.

This underscores the urgent need to develop a stable delivery system capable of protecting Neu5Ac from gastric degradation and achieving its controlled release in the intestine. To enhance the stability and achieve controlled release, Neu5Ac was encapsulated within water-in-oil-in-water (W1/O/W2) emulsion-based microcapsules in this work. S2 emulsions featured a \"dual-chamber, tri-phase\" structure, comprising a Neu5Ac-chitosan fluid gel (inner aqueous phase), maize oil (oil phase), and an external aqueous phase of 13% sodium starch octenyl succinate, 5% \u03b2-cyclodextrin, 1.5% sodium caseinate, and 0.5% carboxymethyl cellulose. Microstructural analyses confirmed spherical morphology with core-shell architecture and bimodal droplet distribution (1-10\u202f\u03bcm). In addition, S2 emulsions exhibited an encapsulation efficiency (EE) of 92.44%, a zeta potential of -60.80\u202fmV, a Sauter mean diameter (d3,2) of 1.337\u202f\u03bcm, shear-thinning behavior and weak gel network stability.

In vitro digestion, S2 microcapsules exhibited controlled release behavior during simulated intestinal digestion, with a Neu5Ac release rate of 85.61% after 120\u202fmin. In mice, microencapsulated Neu5Ac increased the relative abundance of Akkermansia, Lactobacillus, and Bifidobacterium. This system demonstrates promising potential for the co-delivery and controlled release of Neu5Ac, and shows great promise for expanding its applications in the food industry.",

The lack of effective vaccines and emergence of drug-resistant flukes have prompted research into alternative treatments. Metallic nanoparticles have recently been studied for their potential as anthelmintic agents. This research examined the in vitro anthelmintic activity of copper oxide (CuO-NPs) and zinc oxide nanoparticles (ZnO-NPs) against Dicrocoelium dendriticum. Using adult motility inhibition tests and oxidative stress biomarkers, including glutathione peroxidase , glutathione S-transferase , superoxide dismutase , and malondialdehyde , this study evaluated the effects of CuO-NPs and ZnO-NPs. Flukes were treated with various concentrations of nanoparticles (1.00, 4.00, 8.00, 12.00, and 16.00 ppm) for 24 hr. The CuO-NPs and ZnO-NPs demonstrated concentration- and time-dependent anthelmintic activity. Higher concentrations (12.00 and 16.00 ppm of CuO-NPs, and 16.00 ppm of ZnO-NPs) significantly inhibited worm motility compared to the controls. The nanoparticles induced oxidative stress in the flukes, with decreased superoxide dismutase, glutathione S-transferase, and glutathione peroxidase activities and increased malondialdehyde levels. Based on these findings, CuO-NPs and ZnO-NPs exhibit potential as therapeutic agents for controlling and treating D. dendriticum. However, further studies are necessary to assess their safety and efficacy in vivo for managing parasitic infections.",
"42571587": "ID: 42571587\nTitle: Investigation of brain connectivity alteration in the non-severe traumatic brain injury: an emotional condition study.\nAbstract: Traumatic brain injury (TBI) frequently results in persistent emotional and cognitive dysfunction, yet the neural mechanisms underlying these deficits remain incompletely understood. This study examined the impact of non-severe TBI (nTBI) on emotional processing, with a focus on brain activation, functional connectivity, effective connectivity, and their relationship to cognitive performance. Twenty right-handed male nTBI participants (mean age: 30.70\u00a0\u00b1\u00a011.78 years) and 20 age-matched healthy male controls (mean age: 27.85\u00a0\u00b1\u00a07.73 years) underwent functional magnetic resonance imaging (fMRI) while viewing emotional images from the International Affective Picture System (IAPS). Brain activation was analyzed using Statistical Parametric Mapping (SPM12). Functional connectivity was assessed with seed-based analysis (medial visual network, mVN) using the CONN toolbox. Effective connectivity was evaluated using dynamic causal modeling (DCM) and parametric empirical Bayes (PEB). Neuropsychological assessments covering memory, intelligence, and executive function were included to characterize general cognitive function within the cohort, with exploratory analyses examining relationships with connectivity measures. Compared to controls, the nTBI group exhibited reduced activation in the calcarine cortex and lingual gyrus during emotional processing. Functional connectivity analysis showed decreased mVN connectivity with the frontal pole and dorsal anterior cingulate cortex (dACC), with increased mVN-ACC and mVN-supramarginal gyrus connectivity specifically during negative emotion processing. Effective connectivity analysis revealed altered directional influences within visual-limbic-cognitive control networks, including altered mVN-to-dACC and right amygdala-to-dACC connectivity patterns, as well as valence-specific modulation of self-inhibition. Exploratory analyses suggested potential correlations between connectivity alterations and cognitive performance, though these relationships varied across domains and should be interpreted cautiously. Non-severe TBI disrupts emotional network function by altering both functional and effective connectivity, particularly in visual, limbic, and cognitive control regions. These alterations may contribute to emotional dysregulation following injury. Findings support the relevance of brain connectivity-based markers in understanding post-TBI emotional processing and highlight potential targets for intervention. Interpretations should be made cautiously, given the study limitations, including the use of static visual stimuli and a homogenous male sample.",

However, the distinct contributions of polysaccharide charge and viscosity to emulsion formation, stabilization and meat analog quality remain unclear. This study systematically investigated five polysaccharides with different charges and viscosities, namely cationic chitosan (CS), neutral locust bean gum (LBG) and guar gum (GG), and anionic xanthan gum (XG) and high methoxyl pectin (HP), in modulating SPI structure, HIPE performance, and plant-based patty quality. Results showed that polysaccharide charge dominated SPI-polysaccharide interactions and dictated SPI conformational remodeling. Neutral polysaccharides interacted with SPI through hydrogen bonding/hydrophobic interactions, significantly increasing the \u03b2-sheet content (GG: from 35.91% to 43.23%), and achieving the smallest initial droplet size through a high interfacial adsorption rate (GG: 6.81\u202f\u03bcm). During emulsion stabilization and flavor retention, viscosity was the predominant factor. High-viscosity XG and GG excelled in inhibiting droplet aggregation, reducing gravitational separation, and maximizing volatile flavor retention under both heating and storage. At the application stage, viscosity predominantly influenced the hardness of patties. This study reveals the division of labor between polysaccharide charge and viscosity across different performance dimensions of HIPEs, guiding polysaccharide selection for tailoring HIPEs in meat analogs.",
"42571606": "ID: 42571606\nTitle: Gas-Shearing Microfluidic Fabrication of Alginate/Chitosan Hydrogel Microreactors for Genipin-Mediated Dual-Mode Lipase Immobilization.\nAbstract: Enzyme immobilization is an effective strategy to improve catalyst recovery and operational stability, but conventional approaches are often limited by diffusion resistance, steric hindrance, and insufficient control over the enzyme microenvironment. Hydrogel-based materials are attractive supports because their hydrated, tunable, and porous networks help preserve enzyme conformation while improving substrate diffusion and mass transfer. Here, a gas-shearing microfluidic strategy was developed to fabricate alginate/chitosan hydrogel microreactors for dual-mode lipase immobilization through entrapment and genipin-mediated covalent binding. By tuning gas-liquid shear, microspheres with controllable and narrow size distribution were generated without surfactants or UV-initiated polymerization. Importantly, genipin was introduced as a mild and biocompatible cross-linker to reinforce the alginate/chitosan network and create a stable interfacial microenvironment for enzyme immobilization. Compared with conventional cross-linkers, the milder and more controllable reactivity of genipin is advantageous in preserving enzyme conformation and catalytic performance. The resulting microreactors exhibited enhanced catalytic activity, improved storage stability, and good reusability. After five consecutive cycles, the entrapped and covalently immobilized systems retained 70% and 81% of their initial activity, respectively. These results demonstrate that gas-shearing microfluidics combined with genipin-mediated network reinforcement provides a robust and biocompatible platform for constructing hydrogel-based enzymatic microreactors with improved catalytic performance and operational durability.",
"42571607": "ID: 42571607\nTitle: Trions as Fundamental Species in Chemically Doped Polymer Semiconductors.\nAbstract: Doping is a cornerstone strategy for enhancing charge transport in semiconducting polymers, important for their application in, for example, semi-transparent electrode materials, thermoelectric devices, and antistatic coatings. Both chemical and electrochemical doping have, for this purpose, been the focus of extensive research resulting in considerable progress. However, the interactions between neutral excitons and doping-induced charges to form multi-particle states are largely unexplored in soft organic semiconductors, and their signatures remain poorly understood. Here, we demonstrate that coupling between excitons and polarons in doped polymers can lead to bound states such as trions (i.e., quasiparticles of an electron and two holes delocalized across three chromophores for p-doping), or bound exciton-hole pairs. Combining spectroscopic evidence with theoretical insights, we hypothesize that polymer architecture, dopant chemistry, and charge delocalization govern the formation and stability of these multi-particle states. More broadly, our findings reveal that trions and bound exciton-hole pairs-that is, three-body entities-are a key species in organic semiconductors that could open new pathways toward optoelectronic functionalities beyond conventional doping, including enhanced charge transport and quantum-coherent excitations.",
"42571610": "ID: 42571610\nTitle: Antiphase Boundaries Regulate Phase Stability and Performance in DMA+-Assisted CsPbI3-Based Perovskites.\nAbstract: CsPbI3-based perovskites are promising absorbers for tandem solar cells owing to their optimal bandgap (\u223c1.7\u00a0eV). However, the phase transition from photoactive \u03b3-CsPbI3 to non-photoactive \u03b4-CsPbI3 remains a major obstacle and is strongly governed by microstructural defects formed during film growth. Among these, Ruddlesden-Popper antiphase boundaries (RP-APBs) are particularly prevalent and exhibit competing effects, relieving lattice strain while simultaneously facilitating moisture penetration, ion migration, and nonradiative recombination. Here, we systematically regulate RP-APB defects in \u03b3-phase CsPbI3 thin films and elucidate their decisive influence on both phase stability and optoelectronic performance. A compositional strategy based on PbI2 excess effectively reduces RP-APB density but induces edge-sharing [PbI6]4- motifs that nucleate the \u03b4 phase. In contrast, a dimethylammonium (DMA+)-assisted phase-engineering strategy forms \u03b2-(DMA,Cs)PbI3, which intrinsically suppresses RP-APB formation while preserving the photoactive perovskite framework. As a result, RP-APB-free \u03b2-phase films exhibit prolonged carrier lifetimes, strongly suppressed nonradiative recombination, and the lowest apparent trap densities, enabling a champion power conversion efficiency of 20.23% together with markedly enhanced operational, thermal, and ambient-air stability. This work demonstrates that regulating crystalline defects, exemplified by RP-APBs, plays a critical role in achieving both stable and efficient perovskite solar cells.",
"42571611": "ID: 42571611\nTitle: Dual Oxygen Precursors Boosting the Ionic Conductivity of Glassy Electrolytes for All-Solid-State Sodium Batteries.\nAbstract: Amorphous halide-based solid electrolytes (SEs) are promising candidates for all-solid-state Na batteries (ASSNaBs) due to their structural flexibility and favorable mechanical properties. Among them, aluminum-based halide electrolytes are particularly attractive owing to their low cost and oxidative stability; however, previously reported systems typically exhibit limited room-temperature ionic conductivity (<1 mS cm-1). In this work, we report the synthesis of a transparent, viscoelastic Na-Al SE with the specific composition\u00a00.6NaClO-AlCl3-0.175SeO2, achieved through the strategic introduction of dual oxygen sources (NaClO and SeO2). This approach enables the modulation of charge carrier concentrations while simultaneously supplying sufficient oxygen. Furthermore, we introduce the concept of deoxygenation enthalpy to rationalize the selection of these dual oxygen sources among various oxide candidates. The resulting electrolyte achieves a high Na+ conductivity of 2.03 mS cm-1 at ambient temperatures, among the highest reported for Na-Al halide electrolytes. Molecular dynamics simulations confirm that segmental motion within the disordered framework actively facilitates Na+ transport, underpinning the observed viscoelastic behavior. When integrated into ASSNaB with uncoated NaNi0.4Fe0.2Mn0.4O2 cathode, the electrolyte enables stable long-term cycling and superior thermal compatibility, demonstrating practical applicability. This work establishes a new paradigm in rational precursor design for high-performance viscoelastic SEs.",

However, flexible sensors always face challenges in achieving underwater superior self-healing performance and high sensitivity simultaneously. Here, inspired by human skin, we present a method combining force-driven wool spiral regulation with high-temperature to fabricate a flexible sensor with random wrinkled microstructures. Importantly, the sensor resumed usable output within just 8\u00a0min of incurring damage because dynamic borate ester bonds were applied to accelerate its underwater self-healing rate via hydrolysis-re esterification reactions. This bionic self-healing wrinkled flexible sensor achieves high underwater sensitivity, with average response and recovery time of only 124\u00a0ms and 112\u00a0ms, respectively, compared with most reported underwater flexible sensors with the same type of material of exceeding 200\u00a0ms. Notably, it maintains signal stability and functional continuity over 5,000 cycles following underwater self-healing. We further demonstrated its use in underwater vehicle model and human motion for confirming its underwater continuously outputting stable and sensitive signals. These findings advance the underwater self-healing flexible sensing units, with the potential to solve long-term and high-sensitivity condition monitoring towards underwater robotics, and water-resistant human-machine interfaces.",

The biological properties of oximes are directly related to the chemical properties of their functional groups, metal-binding capacities, and ability to interact with biological targets in a multifaceted way. This study presents the synthesis of 5-hydroxyimino 2a-b and 5-methoxyimino 2c derivatives from 5-oxo pentanoic acid methyl esters (1a-c) containing phenyl, p-chlorophenyl, and thiophenyl groups, elucidation of their structures through various spectroscopic analysis methods (IR, 1H NMR, 13C NMR, MS, and elemental analysis), and investigation of their elastase inhibition activities. In the elastase inhibition results, compounds were found to exhibit antielastase activity. Compound 2a, containing the p-chlorophenyl substituent, had the highest antielastase activity (IC50\u00a0=\u00a0426.68\u00a0\u00b1\u00a046.90\u00a0\u00b5M) and was found to have a lower IC50 value compared to the positive control, ursolic acid (486.19\u00a0\u00b1\u00a044.22\u00a0\u00b5M). Furthermore, molecular docking was used to predict binding affinities and found to be -5.8\u00a0kcal/mol for compound 2a and -6.8\u00a0kcal/mol for ursolic acid. Molecular dynamics simulations were conducted to evaluate the stability of protein-ligand interactions. These results suggest that compound 2a could be a potential elastase inhibitor candidate and scaffold for pharmaceutical or cosmetic applications.",

However, the exploration of phosphors that possess both high luminous efficiency and outstanding thermal stability continues to pose significant difficulties. Among various NIR phosphor systems, Cr3+-doped MgGa2O4 (MGO:Cr3+) exhibits characteristic broadband emission. Herein, Bi3+ ions were incorporated as sensitizers into the MGO:Cr3+ phosphor system, resulting in substantial enhancements in photoluminescence (PL), mechanoluminescence (ML), and thermal stability. The Bi3+ co-doping enhanced the NIR PL intensity to 4.0 times and the ML output to 1.45 times those of the Cr3+ singly doped reference, indicating a pronounced sensitization effect and improved energy transfer efficiency. Furthermore, the emission-intensity retention at 423 K improved from 49.29 to 82.88%, confirming a significant enhancement in the thermal stability of the NIR emission. A broadband NIR phosphor-converted light-emitting diode (pc-LED) assembled by coupling the Bi3+, Cr3+-co-doped MGO with a blue LED further demonstrated the material's potential for nondestructive testing, night-vision imaging, and anti-counterfeiting.",

Comparing conventional hydro-distillation (HD) to microwave-assisted extraction (MAE), researchers found that MAE delivered higher oil yields (0.35%-0.37%) than HD (0.31%-0.34%) in significantly less time. Gas chromatography-mass spectrometry (GC/MS) identified 19 volatile compounds-predominantly oxygenated monoterpenes like pinocarvone, \u03b1-thujone, and camphene-with statistical analyses confirming that both location and extraction technique distinctly altered this chemical composition. Furthermore, MAE-extracted oils demonstrated superior antimicrobial activity, particularly those from El Alamein, which reached a notable 25\u00a0mm inhibition zone against Aspergillus niger. Ultimately, the results indicate that MAE is a highly efficient and reproducible method for harvesting bioactive C. cinerea oils for potential pharmaceutical and nutraceutical applications.",

X-ray diffraction (XRD) confirmed the monoclinic crystalline structure of CuO with an average crystallite size of \u223c12\u00a0nm, and successful integration of Ch, Ag, and Se without phase impurities. FTIR analysis revealed strong interactions between CuO and Ch functional groups, evidenced by spectral shifts and peak broadening, suggesting hydrogen bonding and structural modifications. Morphological analysis via electron microscopy showed a transition from aggregated nanosheets to homogeneous nanospheres upon doping with Ag and Se. Composite TS1 (CuO) exhibited superior antimicrobial activity, surpassing the standard drugs imipenem and fluconazole (FLZ) in terms of inhibition zones and minimum inhibitory concentrations (MICs). Sub-MIC concentrations of the composites did not affect the growth of Candida albicans, validating their use in biofilm inhibition assays. Notably, TS1 and TS4 (Ch\u2500CuO\u2500Se) significantly enhanced the efficacy of FLZ, reducing its MIC and MBEC values by up to 8-fold. Biofilm inhibition reached 82.2% with TS1-FLZ synergy.

In this work, lactoferrin (LF) was combined with chlorogenic acid (CGA) to construct the LF-CGA complex to prepare a eugenol (EG) Pickering emulsion (ELC/PE). The surface activity and binding mechanism of LF-CGA were explored. Additionally, the antioxidant, antibacterial, and anti-inflammatory capacities of ELC/PE were compared. The contact angle of LF-CGA approached 90\u00b0 (81.9\u00b0), indicating enhanced stability at the oil-water interface. The interaction between LF and CGA was primarily driven by static quenching and hydrogen bonding. The ELC/PE consisted of 1.5\u00a0wt% LF-CGA, with distilled water and EG as the aqueous and oil phases (15:1\u00a0v/v, aqueous/oil). The DPPH-, O2 -, and ABTS+ scavenging rates of ELC/PE were 86.3%, 75.3%, and 83.4%, respectively. The ELC/PE displayed superior antibacterial ability, along with inhibition rates of 99.0% and 99.5% against Candida albicans and Staphylococcus aureus, respectively. Additionally, the ELC/PE exhibited the most significant suppression of ear swelling (81.8%), confirming its anti-inflammatory ability. These values were the highest among all experimental groups. The LF-CGA complex acts as an emulsifier to enhance EG bioactivities. This novel complex holds great potential for expanding the practical applications of poorly soluble bioactive compounds.",

The lasso architecture is thought to be responsible for its remarkable thermal stability (100\u00b0C for 30\u2009min incubation) and potency against Gram-negative bacteria (i.e., MBC of ~4.75\u2009\u00b5M against E. coli strain DH5\u03b1). This naturally occurring lasso peptide is formed via post-translational modifications (PTMs), including leader peptide removal and macrolactam cyclization between the N-terminus and 8-Glu side chain. Since the discovery of MccJ25 in 1992, synthetic endeavors toward the total chemical synthesis of MccJ25 have remained elusive. Herein, we investigated the chemical synthesis of MccJ25 utilizing \u03b2-thiol amino acids as the chemical tools to prestaple and rigidify the peptide backbone through disulfide linkages. Although the proposed chemical strategy failed to afford the desired lasso configuration, synthetic routes toward Fmoc-SPPS compatible, stereoselective \u03b2-thiol amino acids via thiazoline derivatives were developed. In addition, chemical/biochemical literature synthesis of MccJ25 and its analogs, as well as the synthesis of \u03b2-thiol amino acids, are summarized within.",

Although its antibiotic biosynthetic capacity has been extensively investigated, its siderophore diversity and any additional biological functions of these iron-chelating metabolites remain comparatively underexplored. We identified a reproducibly bioactive, teicoplanin-independent fraction that inhibited Bacillus spizizenii. Molecular networking applied to this fraction identified hydroxamate ferrioxamine and desferrioxamine-type siderophores as the dominant metabolites, including acylated analogs detected as Al3+- and Fe3+-chelated species. Robust siderophore secretion was confirmed by the CAS assay. Notably, siderophore-enriched fractions exhibited selective antibacterial activity against Gram-positive bacteria, with minimum inhibitory concentrations of approximately 16 \u00b5g/mL against B. spizizenii and partial inhibition of Staphylococcus aureus, while no activity was observed against Escherichia coli. Synthetic C7 and C9 acyl-desferrioxamine analogs showed enhanced antibacterial activity upon Al3+ chelation, indicating a metal-dependent bioactivity. These findings reveal an unexpected antibacterial role for ferrioxamine-type siderophores produced by A. teichomyceticus, extending their function beyond iron acquisition, possibly through a \"Trojan horse\" (or \"Trojan metal\") mechanism.",

Herein, we present near-infrared (NIR)-activated enteric prodrug microparticles, HPMCP@L-UCNPs-ONB-5-FU, which enable spatiotemporally controlled release of 5-FU in the colon. The photocleavable prodrug o-nitrobenzyl-5-fluorouracil (ONB-5-FU) is conjugated to large upconversion nanoparticles (L-UCNPs) and encapsulated within the enteric polymer hydroxypropyl methylcellulose phthalate (HPMCP) to resist gastric degradation. After oral administration, low-power 980 nm excitation yields 800 nm emission for bioimaging, whereas high-power excitation generates strong 365 nm emission that cleaves the ONB linker and locally releases active 5-FU. In vitro studies confirmed light-gated and power-dependent drug release, while cellular and orthotopic CRC studies demonstrated potent tumor inhibition with minimal systemic toxicity. Overall, this work establishes a precise and biocompatible NIR-controlled prodrug activation paradigm for oral chemotherapy of CRC.",

Here we report a Ce3+-activated CaZrO3 perovskite phosphor with a low dopant level of about 0.40 atom % Ce quantified by EDS, and we evaluate its pressure-dependent luminescence response. Powder XRD and SEM-EDS confirm a single-phase CaZrO3 host and successful incorporation of the Ce activator. Temperature-dependent photoluminescence and lifetime measurements reveal that the material exhibits good thermal stability. Under compression up to 45 GPa, the broadband Ce3+ 5d-4f emission exhibits an almost linear redshift of the band centroid with d\u03bb/dP about 2.45 nm GPa-1 and a concurrent broadening of FWHM with dFWHM/dP about 1.15 nm GPa-1. In parallel, the CIE 1931 chromaticity coordinates derived from the full emission spectrum evolve regularly with pressure, enabling a continuous color change from blue to green and offering a convenient visual readout. High-pressure Raman spectra indicate a structural transition near 30 GPa, consistent with synchrotron XRD reports for CaZrO3, yet no discontinuity is observed in the pressure dependences of the luminescence parameters. First-principles calculations suggest that compression is mainly accommodated by ZrO6 octahedral tilting and anisotropic polyhedral compression, whereas the local Ce-O crystal-field environment evolves smoothly, accounting for the continuous optical response through the transition. These results establish CaZrO3:Ce3+ as a wide-range, multi-parameter optical manometer for high-pressure calibration at room temperature.",

This study explores the chemical and biotechnological potential of S. plicata collected from Albufeira Lagoon, Portugal, through LC-MS/MS profiling and biological activity assays. Three crude extracts (SP1, ethyl acetate, SP2, dichloromethane:methanol 2:1, and\u00a0SP3, isooctane) were analyzed using LC-MS/MS, annotating 28 major metabolites across eight chemical families: lipids, nucleosides/nucleotides, amino acids, heterocycles, alkaloids/indole derivatives, carbohydrates, thioglucosides, and halogenated. While no antibacterial activity was observed against Staphylococcus aureus (MRSA, MSSA) or Escherichia coli, all extracts displayed significant antibiofilm effects, with SP3 achieving 89.24% inhibition of S. aureus biofilm formation at a minimum biofilm inhibitory concentration (MBIC) of 250 \u00b5g/mL with minimal impact on bacterial growth. Furthermore, SP3 exhibited cytotoxicity (<1% cell viability) against HCT-116 colorectal cancer cells. These findings demonstrate that S. plicata, an invasive pest, produces metabolites of biotechnological relevance, supporting its valorization within circular bioeconomy frameworks as a sustainable source of antibiofilm and cytotoxic agents."

Core objectives include quantifying the modulation of BAG3 and HSP70 expression in macrophages and Huh7 cell lines [ID: Run2_Eval1_synthesis]. Advanced imaging techniques, specifically confocal microscopy, are proposed to assess the lysosomal colocalization and spatial interaction of VP40 with nanovesicle markers [ID: Run1_Eval1_synthesis, Run2_Eval1_synthesis]. Furthermore, VLP budding assays serve as the primary functional metric for determining the suppressive capacity of these nanovesicles on VP40 egress [ID: Run1_Eval1_synthesis, Run2_Eval1_synthesis]."

"content": "The literature indicates a bifurcated research focus regarding ginger-derived exosome therapy. Initial evaluations [ID: Run1_Eval1] emphasize comparative efficacy against rapamycin for EBOV VP40 inhibition and the development of hydrogel-based delivery vehicles. Subsequent evaluations [ID: Run2_Eval1] shift towards mechanistic optimization, specifically pH-dependent stability of [6]-shogaol, quantification of CASA-mediated viral clearance, and longitudinal assessments of proteostasis. A critical evidence gap exists regarding the transition from controlled cell culture environments to complex systemic delivery models, as the current literature primarily relies on primary macrophage cultures."

"content": "The analysis identifies a high-potential therapeutic bridge centered on BAG3-mediated Chaperone-Assisted Selective Autophagy (CASA). In the antiviral domain, ginger-derived nanovesicles show promise in modulating autophagy to restrict Filovirus VP40 egress [ID: 36598950, 36763514]. Concurrently, this mechanism demonstrates significant cross-modal relevance for neurodegenerative proteinopathies, specifically by mitigating TDP-43 synaptic accumulation [ID: 36968202]. The core biological rationale suggests that augmenting the CASA pathway via plant-derived exosomes provides a robust, biocompatible platform for proteostasis regulation across distinct pathogenic conditions."

Subsequent validation in Run 2 reaffirmed this alignment, noting that the mechanisms of BAG3/HSP70 protein degradation remain consistent across studies [ID: Run2_Eval1]. Observed variations in co-chaperone specificity are categorized not as contradictions, but as cellular triage adjustments specific to individual cell types [ID: Run2_Eval1]."

Initial evaluations identify these nanovesicles as versatile 'off-the-shelf' vectors, repurposed from gastric disease and dietary supplement contexts to serve as systemic antiviral delivery platforms [ID: Run1_Eval1_synthesis]. Further technical synthesis reveals a more specialized application: the repurposing of [6]-shogaol specifically for chaperone-activation to mitigate viral-induced proteotoxicity, while simultaneously leveraging the nanovesicles as vectors for CASA-modulating phytocompounds [ID: Run2_Eval1_synthesis]. Current evidence gaps include long-term in vivo pharmacokinetic stability and specific molecular efficacy benchmarks against diverse viral families."
