摘要:
摘要:目的 观察华蟾素对人肝癌细胞HepG2/阿霉素(ADM)耐药性的影响并分析其可能的作用机制。方法 用不同浓度的华蟾素处理HepG2和HepG2/ADM细胞24 h,MTT法检测细胞增殖抑制率,计算半数抑制浓度(IC50);倒置显微镜观察细胞形态学变化;药物蓄积实验检测对细胞内药物累积的影响;Western blot实验检测凋亡相关蛋白Bcl-2、Bax、Caspase-9、Caspase-3表达情况。结果 华蟾素能对HepG2和HepG2/ADM细胞具有增殖抑制作用,耐药倍数为4.67;随华蟾素处理浓度升高,HepG2/ADM细胞体积变小,细胞皱缩突起减少,细胞间连接减少;与耐药组比较,华蟾素可提高 HepG2/ADM 细胞对阿霉素的蓄积水平,上调Bax、Caspase-9、Caspase-3蛋白表达(P<0.05),下调 Bcl-2 蛋白表达(P<0.01),促进细胞凋亡。结论 华蟾素能够显著抑制HepG2/ADM细胞增殖,增加ADM在细胞内的蓄积,其作用机制可能与调控Bcl-2/Bax蛋白表达,诱导细胞凋亡有关。
Abstract:
Abstract:Objective To observe the effect of Huachansu on the drug resistance of human liver cancer cells HepG2/doxorubicin (ADM) and its possible mechanism of action.Methods HepG2 and HepG2/ADM cells were treated with different concentrations of bufalin for 24 hours,and the cell proliferation inhibition rate was detected by MTT assay.The half inhibitory concentration (IC50) was calculated;Observing cellular morphological changes under an inverted microscope;The impact of drug accumulation experiments on intracellular drug accumulation;Western blot assay was used to detect the expression of apoptosis related proteins Bcl-2,Bax,Caspase-9,and Caspase-3.Results The results showed that Huachansu can inhibit the proliferation of HepG2 and HepG2/ADM cells,with a resistance multiple of 4.67;As the concentration of Huachansu increased,the volume of HepG2/ADM cells decreased,the number of cell wrinkled processes decreased,and the intercellular connections decreased;Compared with the drug resistant group,Huachansu can increase the accumulation level of doxorubicin in HepG2/ADM cells,upregulate the expression of Bax,Caspase-9,and Caspase-3 proteins (P<0.05),and downregulate the expression of Bcl-2 protein (P<0.01),promoting cell apoptosis.Conclusion Huachansu can significantly inhibit the proliferation of HepG2/ADM cells,increase the accumulation of ADM in cells,and its mechanism of action may be related to regulating the expression of Bcl-2/Bax protein and inducing cell apoptosis.
