Effects of aesculetin on the proliferation of HepG2 in vitro and investigation of its mechanism
摘要
Abstract
Objective To investigate the effects and mechanism of aesculetin on the proliferation of human hepatoma cell HepG2 in vitro. Methods The proliferation effects of different concentrations of aesculetin on HepG2 were observed by MTT assay. The apoptosis and mitochondria] membrance potential were analysed by flow cytomettry (FCM). The activities of Caspase 3, Caspase 8 and Caspase 9 were detected by spectrophotometry. The protein expressions of Bax, Bcl-2 and Caspase 9 were studied by immunofluorescence method. Results Aesculetin inhibited the proliferation of human hepatoma cell HepG2 and induced its apoptosis, and also reduced its mitochondrial membrane potential, enhanced the activities of Caspase 3 and Caspase 9 by reducing mitochondrial membrance in a dose dependent manner; While there was no significant effect on the activity of Caspase 8. Aesculetin promoted Bax protein expression at the same time lowered Bcl-2 protein expression also in a dose dependent manner. Conclusions Aesculetin can inhibit the proliferation of HepG2; the mechanism may induce its apoptosis through mitochondrial pathway in vitor.关键词
