- W49904557 abstract "目的:研究姜黄素对人前列腺增生间质细胞凋亡的诱导作用。方法:通过MTY法测定姜黄素抑制间质细胞的增殖效应;TUNEL法检测细胞凋亡;RT—PCR技术检测Bcl-2和BaxmRNA的表达;流式细胞术测定凋亡细胞周期的分布。结果:10,20,40μmol·L^-1浓度的姜黄素对增生间质细胞的生长均有抑制作用,这种抑制作用具有时间/剂量依赖性(P〈0.05)。TUNEL结果:与阴性组相比,10,20,40μmol·L^-1浓度的姜黄素可以诱导间质细胞发生凋亡,凋亡率依次为(20.52±2.52)%,(48.33±0.75)%,(84.60±0.57)%(P〈0.01)。RT-PCR结果:姜黄素作用于间质细胞24h,Bcl-2/BaxmRNA的水平下降(P〈0.05)。流式细胞检测发现姜黄素可以诱导人前列腺增生间质细胞周期阻滞于G1期,10,20,40μmol·L^-1浓度的姜黄素组细胞G。期分别为(59.3±4.9)%,(65.2±5.1)%和(71.0±4.7)%。结论:姜黄素可以诱导人良性前列腺增生间质细胞发生凋亡,其机制可能与姜黄素改变凋亡相关基因Bcl-2和BaxmRNA的表达有关。" @default.
