BDH1 Overexpression Alleviates Diabetic Cardiomyopathy via Epigenetic Regulation
Key Highlights
Medicine · Diabetes
A corrected study reports that overexpression of BDH1 (3-hydroxybutyrate dehydrogenase 1) alleviates diabetic cardiomyopathy by inhibiting H3K9bhb-mediated transcriptional activation of LCN2. Researchers demonstrated that BDH1-driven ketone body metabolism suppresses the epigenetic mark H3K9bhb (histone H3 lysine 9 β-hydroxybutyrylation), reducing LCN2 gene expression and consequent myocardial injury in diabetic models. For a leading diabetologist focused on clinical management and complications, this finding offers a novel mechanistic link between ketone metabolism, epigenetic regulation, and cardiac protection in diabetes, potentially informing new therapeutic strategies for diabetic cardiomyopathy.
