Survivin在子宫内膜异位症的表达及其与bcl-2、bax相关性的研究

目的 探讨凋亡抑制基因survivin在子宫内膜异位症的表达,及其与bcl-2、bax的相关性. 方法应用免疫组织化学S-P法,检测40例子宫内膜异位症异位内膜组织中survivin、bcl-2、bax蛋白的表达,并与正常在位子宫内膜组织25例进行对照.结果 子宫内膜异位症异位内膜组织中survivin蛋白阳性表达率为67.5%,明显高于正常在位内膜组织的表达率4.2%(P＜0.05),并且异位内膜组织中survivin蛋白表达与月经周期无相关性(P＜0.05);survivin蛋白表达与bcl-2蛋白呈正相关(P＜0.05),而与bax蛋白呈负相关(P＜0.05). 结论 survivin可通过抑制异位内膜细胞凋亡,对子宫内膜异位症的发生、发展起作用;survivin与bcl-2、bax在子宫内膜异位症的发生、发展中分别起协同和拮抗作用.

Expression of survivin in endometriosis and its relationship with bcl-2 and bax protein

Objective To study the relationship of apoptosis-related gene survivin with bcl-2, bax protein in endometriosis. Methods The expressions of survivin, bcl-2 and bax protein were detected by immunohistochemical method (SP) in ectopic endometrium from 40 cases, and compared with that in eutopic endometrium from 25 cases without endometriosis. Results The expression rate of survivin protein in endometriotic cells was much higher than that in normal endometrial cells. The survivin was not correlated with the phase of menstrual cycle , but positively correlated to bcl-2, negatively to bax. Conclusion Survivin may play an important role in pathogenesis of endometriosis. With survivin gene, apoptosis-related gene bcl-2 may have a synergic role and bax have an antagonistic role in the formation and progression of endometriosis.
