Survivin和基质金属蛋白酶-9基因在卵巢癌中的表达及其临床意义

目的 探讨基质金属蛋白酶(MMP)-9、凋亡抑制基因Survivin与卵巢癌局部侵袭、发生、发展的关系.方法 收集正常上皮来源卵巢组织(n=20)、良性上皮性卵巢囊肿(n=30)、卵巢交界性肿瘤(n=11)和上皮性卵巢癌(n=64),采用免疫组织化学SP法进行定性分析,然后利用RT-PCR法检测Snrvivin和MMP-9基因的表达.结果 Survivin在正常卵巢组织、卵巢良性囊肿、卵巢交界性肿瘤及卵巢癌中阳性表达率分别为20.00%、20.00%、36.67%及76.56%,MMP-9在上述各组中阳性表达率分别为25.00%、23.33%、45.45%及79.68%;与正常卵巢组织、良性上皮性卵巢囊肿比较,卵巢癌组织中Survivin和MMP-9的表达增高明显(P<0.05).Survivin、MMP-9基因的表达分别为:正常卵巢组织(0.21±0.03)、(0.23±0.03);良性卵巢囊肿(0.19±0.05)、(0.21±0.05);卵巢交界性肿瘤(0.38±0.02)、(0.44±0.02);上皮性卵巢癌(0.58±0.02)、(0.59±0.04);与正常组比较均增加,良性上皮性卵巢囊肿、卵巢癌组织中Survivin和MMP-9的表达增高明显,差异有统计学意义(P<0.05).结论 卵巢肿瘤中Survivin和MMP-9的过度表达,促进了卵巢肿瘤的形成与发展.

Abstract：

Objective To detect the expression of MMP-9 and Survivin in ovary cancer and investigate their relationship in local invasion, genesis and development of ovarian cancer. Methods The tissues samples from 64 cases of epithelial ovarian cancer,30 cases of carcinoid, 11 cases of borderline tumor and 20 cases of normal were collected, expressions of MMP-9 and Survivin were detected by immuohistochemistry SP method and RT-PCR. Results The expression positive rates of Survivin were 20.00 %, 20.00 %, 36.67 % and 76.56 %, and the positive rates of MMP-9 were 25.00 %, 23.33 %, 45.45 % and 79.68 % in normal ovarian tissues, carcinoid, borderline tumor and epithelial cancer of ovary, respectively. The positive rates of MMP-9 and Survivin were were higher in ovary epithelial cancer carcinoid than those in carcinoid and normal ovarian tissues(P <0.05). The mRNA of Survivin were (0.21 ±0.03), (0.19± 0.05), (0.38±0.02) and (0.58±0.02), and the mRNA of MMP-9 were (0.23±0.03), (0.21±0.05), (0.44±0.02) and (0.59±0.04) in normal ovarian tissues, carcinoid, borderline tumor and epithelial cancer of ovary, respectively.The mRNA levels of Survivin and MMP-9 were higher in carcinoid and epithelial cancer of ovary than those in normal ovarian tissues. Conclusion The over expressions of Survivin and MMP-9 are related to genesis and development of ovarian cancer.
