摘要 目的探讨KAI1通过调控Integrinβ1通路抑制卵巢癌侵袭的可能机制。方法采用免疫组化En Vision法检测60例上皮性卵巢癌组织、25例正常卵巢组织、21例良性上皮性卵巢肿瘤组织中KAI1蛋白与Integrinβ1蛋白表达的关系; Western blot法检测KAI1在人上皮性卵巢癌细胞株A2780、HO-8910、SKOV3细胞和人正常卵巢上皮细胞株HOSEpi C中的表达;构建高表达质粒EGFP-KAI1转染HO-8910细胞株后,使用Western blot法检测KAI1、Integrinβ1、MMP-7、MMP-9的表达。结果随着上皮性卵巢癌病理学分级及临床分期的增高,KAI1蛋白阳性率降低,Integrinβ1蛋白阳性率升高,KAI1与Integrinβ1表达呈负相关(P <0. 05),在卵巢癌细胞株上亦观察到相似结果;相对于对照组,KAI1高表达组中Integrinβ1、MMP-7、MMP-9表达下调,细胞侵袭、转移能力下降。结论 KAI1可能通过调控Integrinβ1通路抑制卵巢癌侵袭、转移,为探究KAI1抑制肿瘤发生、发展提供新思路。
