摘要
目的阐明HBV对感染细胞凋亡的影响。方法HepG2及其转染HBV的HepG2215细胞培养中,加MTX、ActD或去血清培养,以FCM检测细胞凋亡率。结果HepG2.2.15细胞加MTX后24小时和48小时,凋亡率分别为108%和133%,加ActD后分别为168%和377%,去血清后第4天及第6天,分别为132%和148%;而HepG2细胞加MTX后24小时和48小时,凋亡率则为126%和653%,加ActD后分别为445%和897%,去血清后第4天和第6天凋亡率为198%和288%。结论在上述条件下,HepG2215细胞较HepG2细胞耐受凋亡;HBV可能抑制肝癌细胞凋亡。
Objective To elucidate the effect of HBV on hepatocyte apoptosis. Methods The HepG2 cells and the HBV transfected HepG2.2.15 cells were cultured with MIX or ActD or cultured in DMEM medium without serum, The apoptosis was examined with FCM. Results The apoptotic rates of HepG2.2.15 cells at 24 h and 48 h after MTX addition were 10.8% and 13.3%, at 24 h and 48 h after Act D addition were 16.8% and 37.7%, and at 4 th and 6 th day after serum withdrawal were 13.2% and 14.8%, respectively. While those of HepG2 cells were 12.6% and 65.3%, 44.5% and 89.7%, and 19.8% and 28.8%, correspondingly. Conclusion HepG2.2.15 cell was tolerant to these apoptotic stimuli, and it might be inferred that HBV inhibits hepatocyte apoptosis.
