| 摘 要： | 目的该实验拟研究鸦胆子油乳注射液对人脑胶质瘤U251细胞生长抑制及诱导细胞凋亡的作用。方法体外培养人脑胶质瘤细胞U251,利用MTT比色法检测鸦胆子油乳注射液对于U251的增殖抑制影响;用流式细胞术(flowcytometry,FCM)分析药物处理前后U251的细胞周期变化;实时荧光定量PCR检测不同处理组中凋亡基因Bcl-2的表达。结果 MTT显示鸦胆子油乳注射液对U251细胞增殖抑制作用呈剂量依赖性,当浓度为10 g.L-1时,对U251细胞增殖的抑制率达到(75.8±2.3)%(P<0.05);流式细胞仪分析显示,用10 g.L-1鸦胆子油乳注射液培养48 h,细胞周期中G1期所占比例增高,S期占细胞周期的比例降低;实时荧光定量PCR结果显示随着鸦胆子油乳注射液的浓度增加凋亡基因Bcl-2 mRNA的表达逐渐减少。与对照组比较P<0.01。结论中药鸦胆子油乳注射液可显著抑制U251胶质瘤细胞细胞增殖及促进其凋亡。
