HIF1A and non-small cell lung carcinoma: Herein, we detected circ_0016760 expression in PESV-treated NSCLC cells, analyzed the impacts of circ_0016760 on malignant development and tube formation of NSCLC cells treated with PESV under hypoxia, and determined whether PESV-mediated NSCLC cell processes was associated with circ_0016760/miR-29b/HIF1A axis.
