摘要 [目的]探讨缺氧诱导因子-1α(HIF-1α)在宫颈癌和宫颈上皮内瘤变中的表达及其生物学意义。[方法]选取1996年至2004年诊断为宫颈癌的存档组织蜡块78例,CIN40例,正常宫颈组织12例。41例新鲜宫颈组织和液基细胞标本取自2005年至2006年手术切除标本。利用免疫组织化学、Western blot和RT-PCR等方法检测宫颈癌、宫颈上皮内瘤变、癌旁组织、正常组织和液基细胞中的HIF-1α表达。[结果]宫颈癌、CINⅡ ̄Ⅲ、CINⅠ和正常组织中HIF-1α的阳性表达率分别为58.9%(46/78)、48.0%(12/25)、6.67%(1/15)、0(0/12);宫颈癌组织中,HIF-1α表达与肿块大小、FIGO分期、组织学分级和淋巴结转移密切相关(P<0.05),与患者年龄无关;宫颈癌组织和CINⅡ ̄Ⅲ中的mRNA和蛋白水平均高于癌旁和正常组织及CINⅠ(P<0.05);液基细胞中宫颈癌和HSIL的mRNA和蛋白水平都高于LSIL及正常细胞(P<0.05)。[结论]HIF-1α可能是宫颈癌形成过程中的早期分子事件,其表达增强与宫颈癌的浸润性发展密切相关,有可能成为新的早期筛查和判断宫颈癌生物学行为的诊断指标。
