Abstract

As a member of the S100 protein family, S100A11 expression is often upregulated in human cancer tissues. Numerous studies have demonstrated that S100A11 plays an important role in the progression of cancer. However, the function of S100A11 in ovarian cancer remains elusive. In the present study, the expression levels of S100A11 were found to be significantly increased in ovarian cancer cells. Subsequently, the expression of S100A11 in ovarian cancer HO8910 cells was knocked down using short hairpin (sh)RNA in order to investigate the biological effects of S100A11 on the progression of the disease. The results demonstrated that knockdown of S100A11 by shRNA inhibited the proliferation, anchorage‑independent growth, invasion and migration of HO8910 cells. In addition, knockdown of S100A11 increased the expression of E‑cadherin and decreased the expression of Snail in HO8910 cells. Collectively, these results indicated that S100A11 was able to promote the growth, invasion and migration of ovarian cancer cells. Therefore, S100A11 may serve as a potential molecular target for the diagnosis and treatment of ovarian cancer.
