Hypoxia Modulates Melanoma Cells Proliferation and Apoptosis via miRNA-210/ISCU/ROS Signaling.

In this study, luciferase reporter assay was used to establish the relationship between miR-210 and ISCU. This research was performed on both cell lines (A2058, G361, and 293T) and tissue samples. We found that miR-210 was upregulated in hypoxia and was elevated in melanoma in comparison with adjacent normal tissues. Expression of ISCU protein was decreased in melanoma tissues, and ISCU gene is a direct target of miR-210. ISCU knockdown with miR-210 enhanced ROS production. The results of our study showed that miR-210/ISCU/ROS axis can serve as a novel therapeutic target in melanoma.
