摘要: 目的观察牛黄天龙胶囊(含药血清)对人子宫内膜癌HEC-B细胞能否诱导凋亡并对其抗癌机制进行探讨。方法实验组分低、中、高3个剂量组并设空白组和阳性对照组进行含药血清的制备;MTT法观察细胞毒作用;细胞排染法观察瘤细胞直接损害实验;吖啶橙/溴化乙锭(AO/EB)双荧光染色法及电镜(TEM)下观察细胞凋亡的形态学变化;流式细胞术(FCM)测定细胞凋亡率并进行细胞周期分析,测定凋亡抑制蛋白survivin和凋亡效应蛋白Caspase-3的表达。结果MTT法:人子宫内膜癌HEC-B细胞经含药血清作用后细胞生长受到明显抑制且以低剂量组抑制率最高。细胞排染法:同一时间段内以低剂量组效果最好,不同时间段内(24、48h)细胞抑制率显著提高(P<0.01)。AO/EB和TEM:实验组均可见到典型细胞凋亡的形态学变化。FCM:实验组各组细胞凋亡率与空白组相比差异有显著性(P<0.01)且以低剂量组最高,细胞周期分析显示实验组G0/G1期细胞明显增多而S期细胞明显减少与空白组相比差异有显著性(P<0.01),Survivin蛋白表达在空白组最高,在实验组表达降低与空白组相比差异有显著性(P<0.01),Caspase-3表达则相反...Abstract: Objective To explore the effect and mechanism of “Niuhuangtianlong capsule” whether can induce apoptosis on human endometrial cancer cell line HEC-B. Methods The test groups were respectively divided into three dose groups low-dose, middle-dose and high-dose group including control group and positive group for medical serum. The cell proliferation inhibition was measured by MTT as well as by the cell refusing stain test. Additionally, HEC-B cell morphology changes of apoptosis were observed by AO/EB double...
