Objective: MicroRNA-1271 (miR-1271) has a role in suppressing cell growth, cell cycle and promoting cell apoptosis in many cancers. This research was to explore the great role of miR-1271 in ovarian cancer (OC). Patients and Methods: RT-qPCR was utilized to evaluate the mRNA levels of miR-1271 and its target gene. The proliferative and invasive abilities were measured using Cell Counting Kit-8 and transwell assays. The overall survival rate of OC patients was assessed by Kaplan-Meier method. Results: miR-1271 was downregulated in OC tissues, and downregulation of miR-1271 predicted a poor outcome of the OC patients. Zinc finger E-box binding homeobox 1 (ZEB1) was a target gene of miR-1271 and its expression was regulated by miR-1271 in OC. The expression of miR-1271 had a negative connection with the expression of ZEB1 in OC tissues. miR-1271 inhibited cell viability and invasion-mediated epithelial-mesenchymal transition in SKOV3 cells. ZEB1 reversed partial roles of miR-1271 on viability and invasion in OC. Conclusion: miR-1271 inhibited cell proliferation and invasion-mediated EMT in OC. The newly identified miR-1271/ZEB1 axis provides novel insight into the pathogenesis of OC.
