Inhibitory effect of fructose-1, 6-diphosphate on adriamycin-induced cardiomyocyte apoptosis in rats / 中国病理生理杂志

ABSTRACT

AIM: To study the effect of fructose-1, 6-diphosphate (FDP) on adriamycin(ADM)-induced cardiomyocyte apoptosis in rats. METHODS: Twenty-four Wistar rats were randomly divided into three groups control group, ADM treated group and FDP intervention group. The contents of malondialdehyde (MDA) and NO - 2/NO - 3, the activities of glutathione peroxidase (GPx) and superoxide dismutase (SOD) were determined by colorimetric method in myocardial tissue, and the cardiomyocyte apoptosis was detected by TUNEL method in myocardial tissue, and the expression of inducible nitric oxide synthase (iNOS) mRNA, Bcl-2 mRNA and Bax mRNA in myocardial tissue were detected by in situ hybridization. RESULTS: The contents of NO - 2/NO - 3 and MDA in myocardial tissue, the expressive levels of iNOS mRNA and Bax mRNA in cardiomyocyes and its apoptotic amounts in FDP intervention group were significantly lower than those in ADM treated group ( P
