摘要
目的 探讨新的凋亡抑制基因survivin在宫颈癌组织中的表达 ,及其与bcl 2和p5 3表达的相关性。方法 应用免疫组织化学链霉菌抗生物素蛋白 过氧化酶连接法 (SP法 ) ,检测survivin、bcl 2、p5 3基因在 10例正常宫颈组织及 5 9例宫颈癌组织中的表达。结果 survivin基因在正常宫颈组织中不表达 ,5 9例宫颈癌组织中 ,4 1例表达阳性 ,占 69 5 %。病理分级为G1～G2 级的宫颈癌的survivin基因表达阳性率为 5 8 1% ( 18/ 3 1) ,G3级为 82 1% ( 2 3 / 2 8) ,两者比较 ,差异有显著性 (P<0 0 5 ) ;临床分期Ⅱ期的宫颈癌的survivin基因表达阳性率为 8例中有 4例 ,Ⅲ期者为 81 8% ( 3 6/4 4 ) ,两者比较 ,差异有显著性 (P <0 0 5 ) ,survivin基因表达阳性率与宫颈癌的病理分级和临床分期呈正相关。宫颈癌组织中p5 3蛋白表达阳性、阴性者中 ,survivin基因表达阳性率分别为 76 7% ( 3 3 / 4 3 )、16例中有 8例 ,两者比较 ,差异有显著性 (P <0 0 5 ) ;bcl 2蛋白表达阳性、阴性者中 ,survivin基因表达阳性率分别为 80 0 % ( 3 6/ 4 5 )、14例中有 5例 ,两者比较 ,差异有显著性 (P <0 0 0 5 ) ,survivin基因表达阳性率与宫颈癌组织中p5 3、bcl 2蛋白表达密切相关。
Objective To study the expression of a novel inhibitor gene of apoptosis, survivin, in cervical carcinoma and its relationship with the expression of bcl 2, p53 genes Methods Using streptavidin biotin peroxidase (SP) method, we examined the expression of survivin, bcl 2 and p53 genes in 10 normal cervical tissues and 59 cervical carcinoma tissues Results Survivin was expressed in 41 of 59 (69 5%) cases of cervical carcinomas In contrast, normal cervical epithelium did not express survivin Overexpression of survivin was related to the tumor grade and clinical stage Survivin positive cases were strongly associated with bcl 2 expression (36/45, 80 0% versus 5 of 14 cases, P <0 005) and p53 expression (33/43, 76 7% versus 8 of 16 cases, P <0 05) Conclusions Apoptosis inhibition by survivin, alone or in cooperation with bcl 2 and p53 may participate in the onset and progression of cervical carcinoma Survivin could be a new diagnostic/therapeutic target in cervical cancer
