摘要:目的:探讨贞芪酪蛋白复合肽对Bel-7402人肝癌细胞分化的诱导作用,及对其端粒酶活性的影响。方法:贞芪酪蛋白复合肽给正常大鼠灌胃,采血制备药物血清。以正常鼠血清为阴性对照,维甲酸(RA)为阳性对照,将药物血清温育Bel-7402人肝癌细胞。噻唑蓝(MTT)比色法测定细胞增殖,图像分析系统测定细胞核质比,放射免疫法测定甲胎蛋白(AFP)含量,动态比色法测定γ-谷氨酰转肽酶(-γGT)和碱性磷酸酶(ALP)活性,多聚酶链反应—酶联免疫吸附法(PCR-ELISA法)检测细胞端粒酶活性。结果:贞芪酪蛋白复合肽药物血清可抑制人肝癌细胞的增殖,显著降低细胞核质比,抑制细胞分泌AFP,降低细胞-γGT活性,升高ALP活性,并有显著抑制人肝癌细胞端粒酶活性的作用。结论:贞芪酪蛋白复合肽具有诱导人肝癌细胞分化的作用,其主要机理可能是抑制了Bel-7402细胞端粒酶活性。
Objective: To study the effect of ligustri-astragali casein co-peptid(LACP)drug serum in inducing differentiation of Bel-7402 human hepatocarcinoma cell(HHC) and its influence of the telomerase activity.Methods: Rats were fed with LACP decoction to prepare the drug-serum of LACP,and the drug-serum was used for Bel-7402 HHC culture.Serum of normal rat,was taken as negative control and that of retinoic acid(RA) as the positive control.Cell proliferation was detected by MTT colorimetric assay,nucleocytoplasm r...
