Objective: To investigate the expression of aquaporin 1 in cervical squamous carcinomas (CSC) and cervical precancerous lesions, and the relationship between the tumor clinicopathological parameters, prognosis and the expression of AQP1. Methods: Immunohistochemical method (EliVision) was used to detect the expression of AQP1 in samples from 106 patients [20 with normal cervical tissue, 30 with cervical intraepithelial neoplasia (stage I and II) and 56 with CSC]. Survival analysis was performed by Kaplan-Meier method. Results: AQP1 protein was expressed in vascular endothelia of all samples. It showed upregulation of AQP1 expression in CSC. There was a significant difference between CSC and normal cervical tissues (P<0.05). AQP1 was expressed in some tumor cells and unexpressed in normal squamous epithelial cells. And APQ1-expressing tumor cells were positively related to lymph node metastasis. Patients with APQ1-expressing tumor cells had the lower survival rate than the ones without. Conclusion: Abnormal expression of AQP1 plays an important role in the development of CSC. Positive expression of AQP1 in tumor cells maybe enhances tumor metastasis and could be used as a marker for tumor prognosis.
