Abstract

NFATc1 (nuclear factor of activated T‑cells c1) is associated with malignancy in several cancer models. However, the expression and function of NFATc1 in ovarian cancer remain elusive. In the present study, we investigated the role of NFATc1 in human epithelial ovarian cancer (EOC) using human ovarian adenocarcinoma SKOV3 cells and patient characteristics. NFATc1 expression was silenced by siRNA in the SKOV3 ovarian cancer cell line and in human ovarian cancer nude mouse xenografts. Real‑time PCR, western blotting, immunohistochemical staining, MTT, flow cytometry, transwell, erasion trace and mouse assays were used to detect NFATc1 expression, cell proliferation, apoptosis, cell invasion and migration, tumor growth and angiogenesis. Survival analysis was performed to assess the correlation between NFATc1 expression and survival. NFATc1 was overexpressed in the SKOV3 ovarian cancer cell line and in human serous/mucinous ovarian cancer tissues. The silencing of NFATc1 expression by siRNA reduced cell proliferation and migration and promoted apoptosis in vitro and decreased the ovarian cancer cell tumorigenesis in vivo in nude mice. NFATc1 overexpression in high‑grade serous ovarian carcinomas was an independent prognostic factor of poor overall survival and of early relapse (P<0.01) in a univariate analysis. Our present data provide evidence that NFATc1 is overexpressed in human serous/mucinous ovarian cancer and is associated with a poor prognosis. NFATc1 silencing regulates the cell cycle, apoptosis, invasion and migration. NFATc1 thus has the potential to be a therapeutic target and to be used in EOC diagnosis and prognosis.
