Evidence shows that peripheral inflammation, glycemic dysregulation, and hyperactivity within the hypothalamic-pituitary-adrenal axis are implicated in both obesity and depression. In this study we investigated the impact of visceral adipose tissue (VAT), a crucial characteristic of obesity, on stress susceptibility in obese mice. Age-matched mice were fed with chow diet (CD) or high-fat diet (HFD), respectively, for 12 weeks. CD mice were deprived of VAT and received transplantation of VAT from HFD mice (TransHFD) or CD mice (TransCD). Extracellular vesicles (EVs) were prepared from VAT of CD or HFD mice, and intravenously injected (100 μg, 4 times in 2 weeks) in naïve mice or injected into hippocampus (5 μg, 4 times in 2 weeks) through implanted bilateral cannula. Depression-like behaviors were assessed 14 days after transplantation. We showed that HFD mice exhibited significantly higher body weight gain and impaired insulin and glucose tolerance, accompanied by increased stress susceptibility. Transplantation of VAT or VAT-derived EVs from HFD mice caused synaptic damage and promoted stress susceptibility in recipient mice. Through inhibiting miRNA biogenesis in the VAT and miRNA sequencing analysis, we demonstrated that miR-140-5p was significantly upregulated in both VAT-EVs and hippocampus of HFD mice. Overexpression of hippocampal miR-140-5p in naïve mice not only facilitated acute stress-induced depression-like behaviors, but also decreased hippocampal CREB-BDNF signaling cascade and synaptic plasticity. Conversely, knockdown of miR-140-5p in the VAT, VAT-EVs or hippocampus of HFD mice protected against acute stress, reducing stress susceptibility that were mediated via CREB-BDNF pathway. In summary, VAT-EVs or the cargo miRNAs in obese mice promote synaptic damage and stress susceptibility, providing potential therapeutic targets for metabolism-related affective disorders.</p>","PeriodicalId":6942,"journal":{"name":"Acta Pharmacologica Sinica","volume":" ","pages":"1221-1235"},"PeriodicalIF":6.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12032276/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143389837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, considerable scientific endeavors have focused on unraveling the molecular mechanisms underlying BRDs and developing inhibitors that target these domains. While these inhibitors compete for binding with the acetylated lysine binding site of BRDs, achieving inhibition of BRD proteins via competitive pocket binding has proven challenging due to the conserved nature of these pockets. To address this limitation, the present study employed dynamic simulations for a comprehensive analysis, leading to the identification of a non-conserved pocket in CECR2 for achieving BRD family inhibition through allosteric modulation.

Lycium barbarum polysaccharides (LBPs) were the first macromolecules reported to mitigate liver fibrosis in carbon tetrachloride (CCl<sub>4</sub>)-treated mice. Herein, a neutral peptidoglycan, named as LBPW, was extracted from the fruit of Lycium barbarum. In this study, we investigated the hepatoprotective mechanisms of LBPW. CCl<sub>4</sub>-induced liver fibrosis mice were administered LBPW (50, 100, 200 mg ·kg<sup>-1</sup> ·d<sup>-1</sup>, i.p.) or (100, 200, 300 mg· kg<sup>-1</sup> ·d<sup>-1</sup>, i.g.) for 6 weeks.

Pharmacokinetic analysis showed that cyanine 5.5 amine (Cy5.5)-labeled LBPW (Cy5.5-LBPW) could be detected in the liver through i.p. and i.g. administration with i.g.-administered Cy5.5-LBPW mainly accumulating in the intestine. In TGF-β1-stimulated LX-2 cells as well as in the liver of CCl<sub>4</sub>-treated mice, we demonstrated that LBPW significantly upregulated Smad7, a negative regulator of TGF-β/Smad signaling, to retard the activation of hepatic stellate cells (HSCs) and prevent liver fibrosis. On the other hand, LBPW significantly boosted the abundance of Akkermansia muciniphila (A. muciniphila) and fortified gut barrier function. We demonstrated that A. muciniphila might be responsible for the efficacy of LBPW since decreasing the abundance of this bacterium by antibiotics (Abs) blocked the effectiveness of LBPW. Overall, our results show that LBPW may exert the hepatoprotective effect via rebalancing TGF-β/Smad7 signaling and propagating gut commensal A. muciniphila, suggesting that LBPW could be leading components to be developed as new drug candidates or nutraceuticals against liver fibrosis.</p>","PeriodicalId":6942,"journal":{"name":"Acta Pharmacologica Sinica","volume":" ","pages":"1329-1344"},"PeriodicalIF":6.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12032012/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142998267","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At present, western medicines like colchicine, febuxostat and allopurinol are the primary treatment strategy to alleviate pain and prevent flare-ups in patients with GA, but they have significant side effects and increased mortality risks.

The integrity of tight junctions (TJs) of glomerular endothelial cells (GECs) is a guarantee of physiological function of glomerular filtration barrier. Mammalian sterile 20-like kinase (MST1) is a key regulatory protein in the blood-brain barrier (BBB), and it regulates the expression of TJs-related proteins in cerebral vascular endothelial cells. Our previous study showed that MST1 was involved in renal tubulointerstitial fibrosis of DKD. In the present study we investigated the role of MST1 in barrier function of GECs of DKD, and explored its regulatory mechanisms. In kidney tissue section of DKD patients and db/db mice, and high glucose (HG)-cultured mouse glomerular endothelial cells (mGECs), we showed that MST1 was inactivated in the GECs of DKD accompanied by disrupted glomerular endothelial barrier. In db/db mice and HG-cultured mGECs, knockdown of MST1 increased proteinuria levels, and disrupted glomerular endothelial barrier through decreasing TJs-related proteins, whereas MST1 overexpression restored glomerular endothelial barrier through regaining TJs-related proteins. In db/db mice and HG-cultured mGECs, we demonstrated that MST1 inhibition induced TJs's disruption of GECs via activating YAP1/TEAD signaling. Verteporfin (an inhibitor of YAP1-TEAD interaction) and PY-60 (a YAP1 agonist) were used to verify the role of YAP1/TEAD signaling in the regulation effect of MST1 on barrier function of mGECs.
