【摘要】 目的：实验结果证明4HPR对Hela细胞具有较强的抑制作用，本文从细胞凋亡角度研究4HPR抑制Hela细胞生长的机理。方法：采用电子显微镜、细胞DNA琼脂糖凝胶电泳、流式细胞仪等方法，分析4HPR诱导Hela细胞凋亡的形态学、生化学及细胞生物学改变特征。结果：电子显微镜下：细胞固缩、核膜扭曲、核染色体聚集成块并靠近核膜；细胞DNA被降解，在1．5％琼脂糖凝胶电泳上出现典型的阶梯状图谱（DNALadder）；流式细胞仪检测出现大量亚二倍体细胞核型峰，二倍体细胞峰减少。结论：上述结果表明，4HPR可诱导Hela细胞凋亡。4HPR抑制Hela细胞生长的机理之一是诱导读细胞凋亡。更多还原

Conclnsion:Abice results showed that 4HPR may induce Hela cells poptosis One of mechanisms of 4HPR mayinduce Hela cells spoptosis ONE of mechanisms of 4HPR inhibit to Hela cells growth was to induce apoptosis更多还原
