KDM5B and non-small cell lung carcinoma: Thereafter, to explore the effect of miR-320a on the radioresistance of NSCLC through regulation of KDM5B by targeting HIF1α, A549 and H23 cells were treated with mimic NC + oe-NC + 10 Gy, miR-320a mimic + oe-NC + 10 Gy, and miR-320a mimic + oe-KDM5B + 10 Gy.
