Nevertheless, the core molecular network linking upstream metabolic dysregulation to the aberrant activation of downstream cardiac fibroblasts remains largely elusive. In this study, we combined in vivo and in vitro approaches with bioinformatics analysis. A high\u2010fat diet\u2010induced mouse model of diabetic myocardial fibrosis was established, and transcriptome sequencing was performed to screen for hub genes, which were subsequently validated in two independent DCM datasets. Single\u2010cell RNA sequencing revealed that PDK4 and ACOT1 were upregulated in cardiac fibroblasts under pathological conditions. In vitro experiments confirmed that high glucose induced the expression of PDK4, ACOT1, and fibrotic markers in human primary cardiac fibroblasts. Molecular docking predicted a potential interaction between PDK4 and ACOT1. Collectively, our findings identify PDK4 and ACOT1 as evolutionarily conserved metabolic hub genes associated with myocardial fibrosis in DCM, suggesting a putative \u201cmetabolism\u2013fibrosis axis\u201d and providing potential therapeutic targets.<\/jats:p>","DOI":"10.1155\/jdr\/1952672","type":"journal-article","created":{"date-parts":[[2026,7,31]],"date-time":"2026-07-31T04:11:58Z","timestamp":1785471118000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Integrated
