摘要 目的探讨促凋亡基因PTEN Bi m蛋白在子宫内膜癌发生发展中的作用。方法应用免疫组化SP方法和Western blot方法检测17例正常增殖期子宫内膜、11例非典型增生子宫内膜及52例子宫内膜癌中PTEN、Bi m蛋白的表达。结果Bi m在正常子宫内膜中阳性表达率为100%,而在非典型增生内膜中阳性表达率开始下降(71.4%),在子宫内膜癌组织中明显下降,(P<0.05),而在子宫内膜癌各组织分级、临床分期及肌层浸润程度之间Bi m蛋白表达阳性率均无明显差异(P>0.05)。正常增殖期子宫内膜组织中PTEN表达量最多,随着内膜细胞的增殖程度的增加,PTEN表达量逐渐下降。结论PTEN Bi m蛋白表达改变与子宫内膜癌的发生密切相关。
