Abstract

Diabetic cardiomyopathy is one of the major complications of diabetes, and due to the increasing number of patients with diabetes it is a growing concern. Diabetes‑induced cardiomyopathy has a complex pathogenesis and histone deacetylase‑mediated epigenetic processes are of prominent importance. The olfactory bromodomain‑containing protein 4 (BRD4) is a protein that recognizes and binds acetylated lysine. It has been reported that the high expression of BRD4 is involved in the process of cardiac hypertrophy. The aim of the present study was to investigate the function of BRD4 in the process of high glucose (HG)‑induced cardiac hypertrophy, and to clarify whether epigenetic regulation involving BRD4 is an important mechanism. It was revealed that BRD4 expression levels were increased in H9C2 cells following 48 h of HG stimulation. This result was also observed in a diabetic rat model. Furthermore, HG stimulation resulted in the upregulation of the myocardial hypertrophy marker, atrial natriuretic peptide, the cytoskeletal protein α‑actin and fibrosis‑associated genes including transforming growth factor‑β, SMAD family member 3, connective tissue growth factor and collagen, type 1, α1. However, administration of the specific BRD4 inhibitor JQ1 (250 nM) for 48 h reversed this phenomenon. Furthermore, protein kinase B (AKT) phosphorylation was activated by HG stimulation and suppressed by JQ1. In conclusion, BRD4 serves an important role in the pathogenesis of HG‑induced cardiomyocyte hypertrophy through the AKT pathway.
