ABSTRACT
AIM: To investigate the relationship between alteration of CHOP/GADD153 protein expression and cardiomyocyte apoptosis induced by angiotensin Ⅱ (AngⅡ), and inhibitory effects of CHOP/GADD153 antisense oligodeoxynucleotide (anti-ODN) on apoptosis in vitro.METHODS: Cultured neonatal cardiomyocytes were exposed to AngⅡ with or without preincubation of CHOP/GADD153 anti-ODN. Variability of myocytes was measured by MTT assay, the lactate dehydrogenase (LDH) release was also detected, the percentage of annexin V positive myocytes was monitored by flow cytometry as apoptosis rate, CHOP/GADD153, Bcl-2 and Bax expressions were determined by Western blotting. RESULTS: Compared with control group, the expression of CHOP/GADD153 was obviously increased from (0.20?0.02 to 0.75?0.06) in AngⅡ group (P
