Inhibition of miR-1205 reversed the effects of circARVCF knockdown on DDP resistance, cell colony formation, migration, invasion, and apoptosis in DDP-resistant GC cells. MKN-45/DDP and AGS/DDP cells were transfected with si-NC, si-circARVCF#1, si-circARVCF#1+in-miR-NC, or si-circARVCF#1+in-miR-1205. (A,B) IC50 of cisplatin was estimated by CCK-8 assay. (C) The colony formation of MKN-45/DDP and AGS/DDP cells was examined with colony formation assay. (D,E) The migration and invasion of MKN-45/DDP and AGS/DDP cells were assessed by transwell assay. (F) The apoptosis of MKN-45/DDP and AGS/DDP cells was analyzed by flow cytometry analysis. (G,H) The protein levels of MRP1, MDR1, Bcl-2 and Bax in MKN-45/DDP and AGS/DDP cells were measured via western blot assay. *p < 0.05.
