子宫颈癌中Gli蛋白过表达的临床病理学意义

目的 研究Gli蛋白检测在子宫颈癌及其癌前病变中的临床病理学意义,并分析Gli蛋白表达与HPV16型感染的关系.方法 32例正常子宫颈上皮、71例子宫颈上皮内瘤变(CIN);其中CIN1 28例、CIN2 18例、CIN3 25例和80例子宫颈鳞状上皮癌(SCC)共183例存档蜡块选自延边大学医院、延边妇幼保健院和延边肿瘤医院病理科.应用PCR技术检测上述组织中HPV16型的感染,并用免疫组化方法在子宫颈病变组织芯片中检测Gli-1、Gli-2、Gli-3蛋白的表达情况.结果 Gli-1和Gli-2蛋白呈胞质和胞核染色,Gli-3蛋白多数呈胞质染色.在子宫颈癌和癌前病变(CIN2/3)中,Gli-1~3呈强阳性,其阳性表达率均显著高于正常子宫颈黏膜上皮.80例子宫颈癌标本中HPV16阳性率是77.5%.在子宫颈癌组织中HPV16阳性组的Gli-1蛋白的胞质阳性率(85.5%,53/62)与强阳性率(85.5%,53/62)以及Gli-2蛋白的胞质阳性率(100%)与胞核强阳性率(100%)均高于HPV16阴性组(Gli-1胞质阳性率与强阳性率均为0,Gli-2胞质阳性率和胞核强阳性率分别为0和50%),差异具有统计学意义(P均<0.05);而3种蛋白表达率与患者的年龄、淋巴结转移、肿瘤学分期和临床分期均无关.结论 Gli-1、Gli-2、Gli-3蛋白过表达可以作为子宫颈癌及其癌前病变的早期辅助诊断指标,Gli蛋白的表达水平与HPV16感染密切相关,且有望成为子宫颈癌靶向治疗的新靶点.

Clinicopathological significance of Gli proteins overexpression in uterine cervical cancers

Purpose To investigate the significance of Gli proteins expression in uterine cervical lesions and its relationship with HPV 16 infection status.Methods Total 183 cases of cervical lesions,including 32 non-neoplastic cervix,71 cervical intraepithelial neoplasia (28 CIN1,18 CIN2,and 25 CIN3) and 80 squamous cell carcinomas (SCCs) were selected from the Department of Pathology,Yanbian University Hospital,Yanbian Women Hospital,and Yanbian Tumor Hospital.Gli-1~3 proteins expression was detected in tissue micro...
