摘要
目的观察人参皂甙(GS)Rb1对人急性早幼粒白血病细胞(HL60)糖皮质激素受体α(GRα)mRNA及受体蛋白表达的调节作用和对细胞生长的影响。方法以四唑盐比色法(MTT法)观察细胞生长,用蛋白印迹法(Westernblot)和反转录-聚合酶链反应(RT-PCR)分析G-Rb1对细胞的GR蛋白和GRαmRNA的改变。结果G-Rb1能够抑制HL60细胞的生长,呈时间和剂量依赖性;经G-Rb1作用后RT-PCR和Westernblot分析,细胞内GRαmRNA以及GR蛋白表达增加。结论G-Rb1可上调HL60细胞GRαmRNA及GR蛋白的表达并抑制细胞生长。
AIM: To investigate the effect of Ginsenoside Rb1(G-Rb1) on transcription of glucocorticoid receptor α (GRα) mRNA and expression of its protein in a acute promyelocytic leukemia cell line. METHODS: Antiproliferation effects of G-Rb1 on HL60 cells were determined by MTT. The transcription of GR mRNA and expression of GR were analyzed by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot, respectively. RESULTS: G-Rb1 inhibited the growth of HL-60 cell line in a time-dependent and dose-dependent manner. After 36 hours treatment with 80 mg/L G-Rb1, the expression of GRα mRNA and GR protein increased. CONCLUSION: G-Rb1 exhibits the inhibitory effects on cell growth in HL60 cells, and increases the expression of GRα mRNA and protein. [
