摘要/Abstract

摘要： 目的：研究中药QHF复方对人肝癌Huh7细胞生长、凋亡和侵袭能力的作用，并初步研究其对肿瘤干细胞表面标志物表达的影响。方法：体外培养人肝癌Huh7细胞，MTT法检测QHF复方对细胞增殖的影响；流式细胞术检测QHF复方对Huh7细胞周期及凋亡的影响；Transwell实验检测QHF复方对Huh7细胞侵袭能力的影响；流式细胞仪检测QHF复方作用后Huh7细胞肿瘤干细胞表面标志物CD133和CD44的表达情况。结果：与溶剂对照组比较，QHF复方能够抑制Huh7细胞增殖，并且这种抑制作用具有剂量和时间依赖性（P均 < 0.05）；QHF复方能诱导细胞凋亡，使其生长周期阻滞在S期；QHF复方能够降低Huh7细胞的侵袭能力（P < 0.05）；并能够下调肿瘤干细胞表面标记物CD133和CD44的表达（P < 0.05）。结论：中药QHF复方能够抑制Huh7细胞的生长、侵袭，这种抑制作用可能与肿瘤干细胞表面标记物CD133和CD44表达的下调有关。

Abstract: OBJECTIVE: To explore the influence of Chinese herbal compound QHF on human Huh7 hepatoma cell proliferation,apoptosis and invasion and expression of surface markers of cancer stem cells. METHODS: Human Huh7 hepatoma cells were cultured in vitro. Cell proliferation inhibition rate was detected by MTT assay;cell cycle,apoptosis and cell surface marker CD133 and CD44 expression were detected by Flow cytometry;transwell experiment was used to observe cell invasion. RESULTS: QHF inhibited the proliferation of Huh7 cells,and there was a dose-dependent inhibitory effect. In addition,QHF promoted apoptosis and significantly increased cell proportion in S phase of the cell cycle. QHF lowered expression of tumor stem cell surface markers:CD133 and CD44. CONCLUSION: QHF was able to inhibit human Huh7 hepatoma cell proliferation and migration in vitro,the inhibition was related to the reduced expression of tumor stem cell surface markers:CD133 and CD44.
