摘要: 目的:研究人参皂苷-Rh2(GS-Rh2)对雌激素依赖性人乳腺癌T47D 细胞增殖和凋亡的影响, 并对可能引起凋亡的机制做一初步探索。方法:采用MTT 比色法观察GS-Rh2 对体外培养的T47D 细胞生长的抑制作用;用光学显微镜观察T47D 细胞用药前后的形态学变化;应用流式细胞仪检测凋亡细胞和细胞周期变化以及Caspase-3 表达的变化。结果:MTT 比色法测定结果显示, T47D 细胞经GS-Rh2 作用后生长受抑制, 呈剂量依赖性和时间依赖性, 半数抑制浓度(IC50)为21. 6 μg/mL; 光学显微镜显示T47D 细胞经GS-Rh2 作用后呈较明显的凋亡形态学改变;流式细胞仪检测证实,GS-Rh2 能在一定浓度范围内诱导T47D 细胞凋亡, 将细胞周期阻滞于G1期, 并使Caspase-3 表达增加。结论:GS-Rh2 能抑制体外培养的T47D 细胞增殖并诱导其凋亡。Caspase-3 表达增加可能是GS-Rh2 诱导T47D 细胞凋亡的机制之一。

Abstract: AIM:To examine the effects of ginsenoside-Rh2(GS-Rh2)on proliferation and apoptosis of human breast cancer cell lines T47D and to explore its potential action mechanism.METHODS:Cell growth inhibition was evaluated by MTT colorimetric assay. Cellular morphology was observed under microscope. Apoptotic cells and the changes of cell cycle were determined by flow cytometry (FCM), and the expression of Caspase-3 protein was detected with FCM, too.RESULTS: MTT colorimetric assay revealed that the inhibition of G-Rh2 to the growth of T47D cells was in a time-and dose-dependent manner. The 50% inhibition concentration (IC50) value was 21. 6 μg/mL. GS-Rh2 was capable of arresting the cell cycle at G1 phase. The expression of Caspase-3 protein was up-regulated after exposure to GS-Rh2.CONCLUSION:GS-Rh2 exhibits the growth inhibition effects and induces apoptosis in the test concentration on T47D cell lines. Apoptosis of T47D cells induced by GSRh2 may be related to arresting cell cycle up-regulating Caspase-3 protein expression.
