Overexpression of several aquaporins (AQPs) has been reported in different types of human cancer but their role in carcinogenesis, for example in the cervix, have yet to be clearly defined. In this study, expression of AQPs in cervical carcinomawas investigated by real-time PCR, immunofluorescent and immunohistochemical assays and evaluated for correlations with clinicopathologic variables. AQP1, 3, 8 exhibited differential expression in cervical carcinoma, corresponding CIN and mild cervicitis. AQP1 was predominantly localized in the microvascular endothelial cell in the stroma of mild cervicitis, CIN and cervical carcinoma. AQP3 and AQP8 were localized in the membrane of normal squamous epithelium and carcinoma cells, local signals being more common than diffuse staining. AQP1 and AQP3 expression was remarkably stronger in cervical cancer than in mild cervicitis and CIN2-3 (P<0.05). AQP8 expression was highest in CIN2-3 (91.7%), but levels in cervical carcinoma were also higher than in mild cervicitis. AQP1, AQP3, AQP8 expression significantly increased in advanced stage, deeper infiltration, metastatic lymph nodes and larger tumor volume (P<0.05). Our findings showed that AQPs might play important roles in cervical carcinogenesis and tumour progression in Uygur women.

Roles of MiR-101 and its Target Gene Cox-2 in Early Diagnosis of Cervical Cancer in Uygur Women

Aims: Early diagnosis is important for cervical cancer treatment. This study aimed to characteriz the microRNA profile and target gene protein levels of cervical cancers in Uygur women for application in early diagnosis. Methods: The profiles of miRNA in cervical cancer and chronic cervicitis were analyzed with miRNAmicroarray V4.0. The expression of miR-101 was detected by real-time PCR and locked nucleotide acid in situ hybridization (LNA-ISH). Cox-2 protein levels were assessed by immunohistochemistry. Results: The microarray identified a set of 12 miRNAs significantly decreased in cervical cancer in comparison to the control group. Quantitative RT-PCR analysis showed miR-101 to be significantly downregulated in cancer tissues (p<0.05) while LNA-ISH showed miR-101 positive rates of 80% (20/25) and 8% (5/25) (p<0.05) in the control and cervical cancer groups. Cox-2 positive rates of cervical cancer and control groups were 84% (21/25) and 8% (2/25) (p<0.05). Conclusions: Use of down-regulation of miR-101 and up-regulation of Cox-2 as markers may play a role in early diagnosis of cervical cancer in Uygur women.

Overexpression of several aquaporins (AQPS) has been reported in different types of human cancer but roles in human carcinogenesis have yet to be clearly defined. Here, we up-regulated expression of the AQP8 gene in SiHa human cervical cancer cells with a lentivirus transfection system and investigated its effects as a potential therapeutic target for cervical cancer. Results showed AQP8 overexpression did not affect their substrate adherence and proliferation, but accelerated migration as assessed by transwell migration and wound healing assays. Moreover, AQP8 overexpression significantly enhanced local invasion of SiHa cells in nude mice. These findings altogether indicate that AQP8 overexpression increases migration of SiHa cells and probably participates in the process of tumor local invasion.
