Inhibition of miR-9 Combined With Cisplatin Targeting APE1 Against Angiogenesis in Osteosarcoma.

Osteosarcoma (OS) is a highly malignant tumor, and chemotherapy resistance suggests poor prognosis in OS patients. In this study, the authors discovered that miR-9 has a pro-angiogenic role in OS. The anti-angiogenic effects of cisplatin were greatly increased when miR-9 was suppressed in OS. In addition, the authors demonstrated that miR-9 plays a pro-angiogenic role by targeting apoptosis-inducing factor 1 (APE1) in OS. Importantly, our in vivo experiments showed that inhibition of miR-9 combined with cisplatin could suppress xenograft tumor growth by targeting APE1 and decreasing angiogenesis in OS. In summary, our results suggest that miR-9 plays a role as a tumor promoter, and inhibiting miR-9 and APE1 is a new strategy for inhibiting OS angiogenesis and chemotherapy resistance.
