Knock-down of hsa_circRNA_103809 increased cisplatin-sensitivity in CR-NSCLC cells by targeting miR-377-3p and GOT1. a-c CCK-8 assay was performed to determine cell proliferation abilities. d-f Trypan blue staining assay was used to examine cell viability. g Annexin V-FITC/PI double staining assay was performed to measure cell apoptosis ratio in CR-NSCLC cells. (Note: “Control: without vectors transfection and cisplatin treatment”). Each experiment was repeated at least 3 times. *P < 0.05
