miRNA-489 was shown to be a suppressor factor in many cancers, however, evidence on the effects and mechanism of miRNA-489 in progression of cervical cancer is limited. So we aimed to determine the function of miRNA-489 in cervical cancer proliferation and apoptosis in our present study. Interestingly, we found that miRNA-489 was significantly down-regulated in cervical cancer tissues. miRNA-489 overexpression inhibited the cell proliferation and improved the cell apoptosis of cervical cancer cells. Further, miRNA-489 over-expression suppressed the activation of PI3K and AKT, and stimulated P53 proteins expression. In conclusion, our results suggested that miRNA-489 may be considered as a biomarker in cervical cancer and had suppressed the cell proliferation and stimulated cell apoptosis via PI3K/AKT/P53 signaling pathway (Fig. 5, Ref. 26).
