摘要: 目的:研究淫羊藿素(ICT)调控Notch-1及Ki-67基因表达对人口腔鳞状细胞癌细胞SCC-9的促凋亡效应,为ICT治疗口腔鳞状细胞癌提供实验依据。方法:分别采用4、8、16、32、64 μmol/L的ICT处理SCC-9细胞,以未采用ICT处理的细胞作为对照组。采用CCK-8法检测细胞存活率,克隆形成实验检测细胞克隆能力,利用流式细胞仪检测细胞凋亡程度,实时定量PCR检测细胞周期调控蛋白Ki-67和跨膜受体Notch-1基因表达水平。结果:经ICT处理的SCC-9细胞的增殖率、克隆数均明显低于对照组,组间比较差异均有统计学意义(P<0.01);经ICT处理的SCC-9细胞中Ki-67和Notch-1基因表达水平明显低于对照组,差异均具有统计学意义(P<0.01)。结论:ICT可通过下调Ki-67、Notch-1因子的表达水平影响SCC-9细胞的增殖及凋亡。

Abstract: Objective: To explore the effect of icaritin (ICT) on the apoptosis of oral squamous cell carcinoma cells-9 (SCC-9) through regulating Ki-67 and Notch-1 gene expression, and to provide experimental basis for ICT treatment of oral squamous cell carcinoma. Methods: SCC-9 cells were treated with 4, 8, 16, 32, and 64 μmol/L ICT respesctively, and equal volume of culture medium was added as blank control group. CCK-8 method was used to detect the cell survival rate. Clone formation test was used to detect the capability of cell clones. Flow cytometry was used to detect the degree of apoptosis,and real-time quantitative PCR was used to detect the mRNA expression levels of Ki-67 and Notch-1. Results: The proliferation rate and clone number of SCC-9 cells treated with ICT were significantly lower than those of control group (P<0.01). The expression levels of Ki-67 and Notch-1 in SCC-9 cells treated with ICT were significantly lower than those of control group (P<0.01). Conclusion: ICT can influence the proliferation and promote apoptosis of SCC-9 cells by down regulating the gene expression of Ki-67 and Notch-1.
