We showed that carrimycin (1.25-10 µM) dose-dependently inhibited both viral RNA and protein levels in Vero E6 cells. We further demonstrated that carrimycin disrupted the formation of SARS-CoV-2 double membrane vesicles (DMVs), and identified the host transmembrane protein B (TMEM41B) as the key factor involved in this process.

Our previous study shows that Yin Yang 1 (YY1), a zinc finger protein, is a novel regulator of DKD-induced renal fibrosis. In this study we investigated the role of YY1 in glomerular MC proliferation in DKD in vivo and in vitro. We first showed that YY1 expression levels were significantly increased in the glomerular MCs of DKD patients and db/db mice and in high glucose (HG)-treated SV40-MES13 cells. By using YY1 expression/knockdown plasmids, we confirmed that YY1 contributed to glomerular MC proliferation in vitro. We demonstrated that YY1 upregulated hypoxia-inducible factor-1 alpha (HIF-1α) expression and activity in HG-treated SV40-MES13 cells, leading to overproduction of mROS. Moreover, mROS contributed to positive feedback regulation of YY1/HIF-1α signaling, and the YY1/HIF-1α/mROS positive feedback loop exacerbated glomerular MC proliferation in HG-treated SV40-MES13 cells. In addition, renal-specific YY1 overexpression promoted glomerular MC proliferation in normal mice, whereas renal-specific YY1 knockdown mitigated MC proliferation in early diabetic mice by inactivating HIF-1α/ROS signaling.

In this study we investigated the role of hepatic FNDC5/Irisin in a mouse model of AILI induced by acetaminophen (APAP, 400 mg/kg, i.p.). The mice were euthanized at 6, 12 and 24 h after APAP injection, then the blood and liver tissues were collected for analyses. By conducting transcriptome sequencing, we identified that both the expression and release of FNDC5/Irisin were significantly increased and highly correlated with AILI. We showed that knockout of Irisin significantly improved APAP-induced tissue damage and hepatocyte death in mouse liver. Conversely, preinjection of recombinant Irisin protein (1 mg·kg<sup>-1</sup>·d<sup>-</sup><sup>1</sup>, i.p., for 3 days) exacerbated the AILI in FNDC5 knockout mice. RNA-seq analysis revealed that knockout of FNDC5/Irisin reduced inflammatory responses and JNK/NF-κB activation in APAP-treated mouse liver, while exogenous Irisin administration aggravated JNK/NF-κB-mediated inflammation. In primary mouse hepatocytes treated with APAP (15 mM), application of Irisin (100 ng/mL) activated the integrin αV/JNK/NF-κB axis, driving inflammation and oxidative stress. In summary, this study highlights Irisin as a critical regulator in AILI progression. Circulating Irisin could be a novel biomarker for AILI diagnosis, and targeting FNDC5/Irisin could hold promise for the development of novel treatments for AILI.</p>","PeriodicalId":6942,"journal":{"name":"Acta Pharmacologica Sinica","volume":" ","pages":"1946-1957"},"PeriodicalIF":6.9,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12205071/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143522398","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}
