Effects of miR-199a-5p on the proliferation, migration and invasion of FTC cells. a The expression of miR-199a-5p in FTC cells transfected with miR-199a-5p mimics/inhibitor or negative controls. b CCK-8 assay was used to detect the cell proliferation ability of FTC-133 cells after transfection with miR-199a-5p mimics or inhibitor. c The Transwell migration/invasion assay number was detected at 72 h after FTC cells were transfected with miR-199a-5p mimics/inhibitor. d Knockdown of PD-L1 expression reversed the promotive effect of the miR-199a-5p inhibitor on cell migration/invasion ability and e cell proliferation in FTC cells. Data are presented as the mean ± standard error based on at least three independent experiments. * p < 0.05, ** p < 0.01, *** p < 0.001
