This study aimed to determine the role of ACSF2 in renal tubule injury in DN and its underlying mechanisms.Methods: We established diabetic kidney disease models both in vivo, using db/db mice, and in vitro, using high glucose induced HK-2 cells.Results: A significant upregulation of ACSF2 was observed in the renal tubules of patients with DN and db/db mice. ACSF2 expression correlated with renal tubule injury and renal function, indicating its potential as an independent biomarker in patients with DN. Silencing ACSF2 alleviated high glucose-induced renal tubular epithelial cell injury by reducing oxidative stress-induced ferroptosis in vivo and in vitro. Mechanistically, liquid chromatography-tandem mass spectrometry and co-immunoprecipitation demonstrated that ACSF2 specifically binds to PGK1. ACSF2 affected Keap1 dimerization by regulating PGK1 phosphorylation at serine 203, which subsequently affects the levels of NRF2. Moreover, PGK1 stabilizes ACSF2 via deubiquitination, establishing a positive feedback loop. The results provide evidence that the interaction between ACSF2 and PGK1 promotes DN progression by regulating oxidative stress-induced ferroptosis.Discussion: ACSF2 participates in crosstalk between oxidative stress and ferroptosis. This could be a potential therapeutic target for DN.","PeriodicalId":21096,"journal":{"name":"Redox Report","volume":"30 1","pages":"2529618"},"PeriodicalIF":5.2,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12269058/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144650221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Demethylation of the CpG island using 5-azacytidine or siRNA-mediated knockdown of DNA methyl transferases significantly upregulated TSLP expression. Sequence analysis revealed the presence of two overlapping SP1 transcription factor DNA-binding sites (DBSs), between -1494 and -1510 nucleotides on the human TSLP promoter. Further experiments showed that demethylation of the CpG island enables the binding of SP1 to its cognate DBS present on the TSLP promoter, resulting in its transcriptional activation. Moreover, retinoic acid-induced transcription of human TSLP was associated with CpG island demethylation and SP1 binding to the TSLP promoter. These findings unravel a distinct mechanism of transcriptional regulation of the human TSLP gene and suggest possible epigenetic regulation of TSLP expression in modulating atopic and allergic disease severity in different individuals.","PeriodicalId":11767,"journal":{"name":"Epigenetics","volume":"20 1","pages":"2529358"},"PeriodicalIF":2.9,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12269656/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144625618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this retrospective cohort study based on 1,942 NHANES participants (median age 65 years; 944 women), we examined the associations between AAs from multiple epigenetic clocks and the risks of all-cause, cancer-specific, and cardiac mortality. Restricted cubic spline models were used to assess the shape of these associations, and Cox proportional hazards regression was employed to quantify risk estimates. Model performance was compared using the Akaike Information Criterion (AIC) and concordance index (C-index). Our findings revealed that only GrimAge AA and GrimAge2 AA demonstrated approximately linear and positive associations with all three mortality outcomes. Both were significantly associated with increased risks of death, and these associations were consistent across most subgroups. GrimAge and GrimAge2 AAs showed very similar performance in predicting all-cause, cancer and cardiac mortality, with only small differences in AIC values and C-index scores.

Initial colonization of all tissues was observed within 16 h, with colonization rates peaking after 5 d, with a preferential colonization rate observed as endosperm > embryo > seed coat. Furthermore, the colonization by I. cateniannulata enhanced peroxidase (POD) activity in the embryo and reduced malondialdehyde (MDA) content.
