摘要: 研究白桦脂醇(Betulin)和白桦脂酸(Betulinic Acid, BA)对3种癌细胞株的增殖抑制作用以及白桦脂酸诱导MCF7细胞毒的分子机制. 应用结晶紫染色方法对白桦脂醇和白桦脂酸对肿瘤细胞的生长抑制作用进行筛选; 应用RT-PCR技术检测MCF7细胞p21 mRNA, p53 mRNA, Bcl2 mRNA和Bax mRNA的表达. 结果表明, 白桦脂醇和白桦脂酸有显著抑制肿瘤细胞生长的作用, 且有浓度依赖性; 白桦脂酸能够诱导MCF7细胞凋亡, 并诱导其p21 mRNA和p53 mRNA表达增高, 但对其Bcl2 mRNA和Bax mRNA 的表达无影响.

关键词: 白桦脂醇, 白桦脂酸, 细胞周期, 凋亡

Abstract: To investigate the antiproliferative effect of betulin and betulinic acid on 3 kinds of human cancer cells and the mechanism of betul inic acid induced cytotoxicity in MCF7 cell line, crystal violet dyeing was used to screen the cytotoxicity effect of betulin and betulinic acid in the cancer cells. RTPCR was operated to determine the expression of p21 mRNA, p53 mRNA, Bcl2 mRNA and Bax mRNA. This study shows that the growth of tumor cells is significantly inhibited by betulin and betulinic acid in dosedependence. The study alsoindicates that betulinic acid induces the apoptosis of MCF7 cells. So a s to make the expression of p21 mRNA and p53 mRNA increased but make the express ion of Bcl2 mRNA and Bax mRNA unchanged.

Key words: betulin, betulinic acid, cell cycle, apoptosis
