Prognostic role of Wnt7a expression in ovarian carcinoma patients
Abstract:
Wnt7a is a secreted glycoprotein that regulates normal cellular proliferation and differentiation as well as tumorigenesis and progression. The aim of this study was to investigate the expression and prognostic significance of Wnt7a in ovarian carcinoma. Wnt7a expression was immunohistochemically examined in normal ovaries (n=15), benign tumors (n=50) and ovarian carcinomas (n=78). The correlation of Wnt7a expression with clinicopathological parameters and survival was evaluated. Wnt7a expression was higher in ovarian carcinomas compared to normal ovaries and benign tumors (pWnt7a positive expression was significantly correlated with serous subtype (pHigh Wnt7a expression in ovarian cancer may be associated with poor prognosis.
