摘要: 目的 观察芒果苷对原代SD乳鼠心肌细胞缺血缺氧凋亡的影响。方法 建立缺血缺氧诱导的SD乳鼠心肌细胞凋亡模型。芒果苷干预后,流式细胞仪检测心肌细胞凋亡率;分光光度法检测细胞裂解液中凋亡蛋白酶Caspase-3、Caspase-9活性;western blot法检测促凋亡蛋白Bax和抗凋亡蛋白Bcl-2的蛋白表达水平。结果 缺血缺氧处理12h能成功建立心肌细胞凋亡模型。经150?M芒果苷处理后,与模型组相比较,心肌细胞凋亡率显著下降(P<0.05);凋亡蛋白酶Caspase-3、Caspase-9活性均显著下降(P<0.05);促凋亡蛋白酶Bax的蛋白表达量显著下降(P<0.05),抑凋亡蛋白酶Bcl-2的蛋白表达量显著上升(P<0.05)。结论 芒果苷能显著抑制缺血缺氧诱导的原代大鼠心肌细胞凋亡。

Abstract: Objective To investigate the effects of mangiferin on myocardial apoptosis induced by hypoxia ischemia in rats. Methods myocardial apoptosis model induced by hypoxia ischemia12h in rats. After mangiferin intervention, myocardial cell apoptosis was deteced by flow cytometry; apoptosis protease Caspase-3, Caspase-9 activity in cell lysates was detected by spectrophotometry; the protein expression of Bax and Bcl-2 was detected by western blot. Results myocardial apoptosis model was successfully established by hypoxia ischemia 12h. Compared with the model group, After mangiferin intervention, myocardial apoptosis rate was significantly decreased (P<0.05); apoptosis protease Caspase-3 and Caspase-9 activity were significantly decreased (P<0.05); the protein expression of the pro apoptotic protein Bax was significantly decreased (P<0.05), and the protein expression of the anti apoptotic protein Bcl-2 was significantly increased (P<0.05). Conclusion Mangiferin can significantly inhibit myocardial apoptosis induced by hypoxic-ischemic.
