Following PRISMA guidelines (Registration No.: INPLASY202560055), PubMed and ScienceDirect databases were searched through 18 January 2026. Two independent reviewers conducted blinded screening via the Rayyan platform. From 1290 initial articles, 71 studies met inclusion criteria. Methodological rigour was assessed using a modified SYRCLE risk-of-bias tool. Thematic synthesis identifies R-loops as recurrent intermediates linking transcription, chromatin regulation, and genome maintenance; feedback-like relationships are reported in selected systems. They spatially impede DNMTs to sustain promoter hypomethylation while recruiting TET enzymes for demethylation, and RNA modifications (e.g. m5C/m6A) may tune hybrid stability and, in some contexts, influence effector recruitment. R-loops facilitate the recruitment of histone-modifying complexes (PRC1/PRC2, G9a/GLP), thereby influencing chromatin landscapes and 3D genome architecture - including associations with TAD boundary insulation and with LLPS-related repair compartments in specific contexts. Dysregulation of R-loop homeostasis links to disease-related epigenetic alterations and genome instability with distinct disease-, locus- and cell-state specificity, and its context-dependent roles in diverse disorders involve transcriptional silencing, DNA damage, replication-transcription conflicts, repair pathways, chromatin regulation and mitochondrial genome maintenance.

While epigenetic ageing, a measure of biological ageing, has been linked to breast cancer risk, prior studies have mainly focused on blood-based measures. We aimed to study well-established epigenetic age estimates in normal breast tissue in relation to obesity-related metabolic markers. We analysed breast tissue from 91 cancer-free women, using DNA methylation age (mAge) clocks, including first-generation clocks (Hannum, Horvath), mortality-related clocks (Grim, Pheno), and methylation-based telomere length (DNAmTL). Pearson correlations assessed relationships among the clocks. Linear regression was used to associate mAge clocks with obesity-related blood markers (leptin, adiponectin, IGF-1, IGFBP-3), adjusting for chronological age, race, body mass index (BMI), and smoking, applying a false discovery rate threshold of 0.1. We explored effect modification by menopausal status using interaction terms. In the normal breast tissue, the strongest correlation of mAge estimates was observed between Horvath-mAge and Grim-mAge (r = 0.85). BMI was positively associated with all mAge estimates except Pheno-mAge. Older Grim-mAge and longer DNAmTL were associated with higher levels of adiponectin, IGF-1, and IGFBP-3, while older Horvath-mAge was associated only with IGF-1. Associations of DNAmTL with IGF-1 and adiponectin differed statistically by menopausal status. Epigenetic age in breast tissue, particularly Grim and DNAmTL, is associated with obesity-related metabolic markers, independent of chronological age, BMI, and smoking.

Generally, DNA methylation counteracts these processes and promotes gene silencing in vertebrates. CTCF is a conserved and essential multifunctional transcription factor relevant for establishing and maintaining chromatin architecture and accessibility, while its precise role in regulating DNA methylation remains to be determined. We focused on the highly abundant and previously studied erythroid-specific α<sup>D</sup> gene (<i>HBAD</i>) to systematically investigate the role of CTCF binding on DNA methylation, chromatin accessibility, and gene expression using a chicken erythroid cell differentiation system. The perturbation of CTCF binding at the intergenic region between the embryonic π and the adult α<sup>D</sup> gene resulted in DNA methylation propagation towards the α<sup>D</sup> gene, which was accompanied by decreased chromatin accessibility, GATA-1 binding, and gene expression. Notably, chromatin conformation analyses revealed that CTCF binding enables α<sup>D</sup> transcriptional activation independently of its architectural function. We observed a similar role of CTCF on DNA methylation and gene expression in the human orthologous gene <i>HBA2</i>. Our findings support a conserved role of CTCF in preventing DNA methylation spreading and gene silencing of cell-type-specific genes along differentiation.</p>","PeriodicalId":11767,"journal":{"name":"Epigenetics","volume":"21 1","pages":"2711190"},"PeriodicalIF":3.7,"publicationDate":"2026-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13436835/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148663622","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}
