Knockdown of ZNF280A inhibits the development and progression of ovarian cancer

Abstract

Background: Ovarian cancer (OC) is one of the leading causes of death from gynecological malignancies worldwide. Abnormal expression of zinc finger proteins has been extensively reported to be involved in malignant progression in a variety of cancers. However, clinical significance and biological roles of ZNF280A in the field of OC are poorly known. Methods: In this study, we demonstrated that ZNF280A was highly expressed in OC tissues compared with adjacent normal tissues. Further, ZNF280A was significantly associated with clinical staging, infiltration, lymphatic metastasis, metastasis, and tumor recurrence of OC patients. Additionally, data of in vitro experiments indicated that knockdown of ZNF280A by its shRNA dramatically reduces the proliferation and migration ability of OC cells, while enhancing the cell apoptosis. Results: It was also verified by animal experiments that ZNF280A silencing would affect the growth of OC in vivo. Our study investigated the involvement of ZNF280A in the prognosis, progression and metastasis of OC. Conclusions: Therefore, our study identified ZNF280A as an optional prognostic factor in OC patients and can be used as a potential therapeutic target for the treatment of OC.
