FOXD3-AS1 regulated MPR1 expression via miR-127-3p/MDM2 axis. a qRT-PCR and western blot analysis of MRP1 expression in A549 and A549/DDP cells. b qRT-PCR and western blot analysis of MRP1 expression in A549/DDP cells after being transfected with different oligonucleotides. miR inhibitors = miR-127-3p inhibitors. N = 3 biological samples and each sample was assayed in triplicates. Significant differences between groups were shown as *P < 0.05 and **P < 0.01
