Abstract

Ovarian cancer is a malignancy with high mortality among women. Multiple reports show that microRNAs (miRs) act as regulators in ovarian cancer inhibition, while the role of miR-1284 in ovarian cancer is still unknown. This study aimed to investigate the effects of miR-1284 on ovarian cancer cells. Human ovarian cancer cell line OVCAR3 was cultured and transfected with miR-1284 mimics, inhibitors, or control. Viability and apoptosis of transfected cells were then determined by MTT assay, BrdU assay, and flow cytometry. Expression changes of p27, p21, and PI3K/Akt pathway-related proteins were measured by Western blot. Results showed that miR-1284 overexpression suppressed cell viability while increasing the apoptosis in OVCAR3 cells. Moreover, the expression level of p27 was upregulated by miR-1284 overexpression. Furthermore, miR-1284 overexpression and Akt inhibitor GSK690693 downregulated the levels of p-Akt and Bcl-2 while upregulating the levels of Bax and caspase 3. However, miR-1284 suppression attenuated the regulatory effects of GSK690693 on these proteins. In conclusion, miR-1284 could inhibit cell viability via regulating the expression of p27 and induce apoptosis via regulating the PI3K/Akt pathway in OVCAR3 cells.
