摘要: 目的: Toll样受体9(Toll-like receptor-9,TLR9)是天然免疫受体之一,近期研究表明TLR9与多种上皮性肿瘤发生的早期行为密切相关。本研究拟从蛋白质水平观察宫颈上皮组织中TLR9表达变化与维吾尔族妇女宫颈癌病理进程的关系。方法:收集维吾尔族妇女宫颈炎、宫颈上皮内瘤变 (cervical intraepithelial neoplasia,CIN)和宫颈鳞癌(cervical squamous cell carcinoma,CSCC)患者的宫颈上皮石蜡包埋组织标本共97例,采用免疫组织化学方法检测各组织中TLR9蛋白表达水平。结果:TLR9蛋白在绝大部分宫颈炎患者的宫颈上皮细胞中不表达(88.2%)或弱表达(11.8%),但是随着宫颈上皮内瘤变和宫颈癌的发生,表达水平逐渐上升,其阳性率依次为慢性宫颈炎(2/17,11.8%),CIN I(4/19,28.6%),CIN II(3/10,30.0%),CIN III(12/24,50.0%),CSCC(17/32,53.1%), 5组之间比较差异有统计学意义(P<0.05),CIN III及CSCC与宫颈炎间的阳性率差异显著 (P<0.05),但是CIN I和CIN II与宫颈炎间的差异无统计学意义 (P>0.05),并且在CSCC中,不同肿瘤分化程度之间其TLR9蛋白阳性率的差异无统计学意义 (P>0.05)。结论:TLR9蛋白可能参与了宫颈癌的发生和发展的进程。

Abstract: OBJECTIVE: The aim of this study was to investigate the association of Toll-like receptor 9 protein expression with cervical cancer pathogenesis. METHODS:Levels of TLR9 protein in chronic cervicitis,cervical intraepithelial neoplasia (CIN) and cervico-squamous cell carcinoma (CSCC) tissues from 97 Uighur patients were examined by immunohistochemistry. RESULTS:Immunohistochemical staining showed that TLR9 expression was mainly observed as cytoplasmic staining and was undetectable (88.2%) or weak (11.8%) in chronic cervicitis tissues,gradually increased in accordance with the histopathological grade in the following order:chronic cervicitis (2/17,11.8%),CIN I (4/19,28.6%),CIN II(3/10,30.0%),CIN III(12/24,50.0%),CSCC(17/32,53.1%). There were statistical differences among five groups (P<0.05). The difference was statistically significant for CIN III and CSCC compared with cervicitis (P<0.05),but not for CIN I and CIN II (P>0.05). CONCLUSION:This study showed that the TLR9 protein expression was,to some extent,associated with the development of cervical precancerous lesion and cancer.
