ABSTRACT
Aim To investigate the role of fenofibrate (FF),a selective PPAR-? agonist,in cardiac hypertrophy induced by high glucose and insulin (HGI) and its mechanisms related to nitric oxided (NO) signal transduction pathway. Methods The cultured neonatal rat cardiomyocytes were used to observe the effects of FF on cardiomyocyte hypertrophy induced by HGI (glucose at 25.5 mmol?L-1 and insulin at 0.1 ?mol?L-1),and the cardiomyocyte hypertrophic responses were assayed by measuring the cell surface area,protein content,and atrial natriuretic factor (ANF) mRNA expression. The expressions of mRNA and protein were assayed by Real-time PCR and Western blot,as well as NOS activity and NO concentration in cultured media were determined by using the spectrophotometry and nitrate reluction method.Results In cultured cardiomyocytes,FF (at 0.1,0.3 and 1 ?mol?L-1) could inhibit the cardiomyocyte hypertrophy induced by HGI in a concentration-dependent manner (P
