摘要
目的:为研究bcl-2的表达与肺癌细胞凋亡发生的关系.方法:采用免疫组化及末端转移酶介导的切口末端标记法(TUNEL).分别对73例肺癌组织进行bcl-2免疫组化染色和细胞凋亡的检测.并对bcl-2表达强度和细胞凋亡指数(Al)进行相关分析,结果:(1)bcl-2在肺癌组织中总的阳性率为27,4%,其中小细胞癌的阳性率为54%;鳞癌阳性率23%;腺癌阳性率18.7%(2)肺癌细胞AI为0到17.6%,其中有13例AI<1%,29例AI在1%到5%之间,31例AI>5%.(3)bcl-2表达的强应与肺癌细胞凋亡指数呈显著负相关.r=0.6216,P<0.01.结论:肺癌组织中bcl-2的过表达可能与抑制细胞凋亡有关.
