Abstract:
Objective To observe the abnormity of heart function in rats with pressure overload-induced left ventricular hypertrophy and the changes of NCX,SERCA2a expression in myocardial tissues. Methods Cardiac hypertrophy was induced by clipping the abdominal aorta in rats. The cardiac hypertrophy was evaluated by Left ventricular weight index(LVWI,left ventricular weight/body weight). NCX, SERCA2a mRNA and protein expressions in left ventricular tissues were determined by half-quantitative RT-PCR and Western blot normalized to abundance of GAPDH mRNA and protein,respectively. Results LVSP and LVEDP were obviously enhanced(P
