A Relative luciferase activities of wild-type (WT) and mutated (MUT) reporter gene vectors of lncRNA-Gm31932 in B16 cells co-transfected with miR-344d-3-5p mimic/miR-344d-3-5p mut. B Principal flowchart of the RNA pull-down experiment. C The miR-344d-3-5p content, which was enriched from the cell lysate by RNA pull down, was detected by RT-qPCR. D The RNA expression level of miR-344d-3-5p was determined in lncRNA-Gm31932 silenced cells. E, F The mRNA expression of miR-344d-3-5p was detected in ATRA- or PB-4-treated B16 cells. G The rescue effect of the miR-344d-3-5p inhibitor on the growth inhibition of B16 cells mediated by silencing lncRNA-Gm31932 was determined by CCK-8 assay. H The rescue effect of miR-344d-3-5p inhibitor on the morphological changes of B16 cells mediated by silencing lncRNA-Gm31932 was observed using a microscope. I The rescue effect of miR-344d-3-5p inhibitor on the cell cycle arrest of B16 cells mediated by silencing lncRNA-Gm31932 was determined by flow cytometry. J Quantitative analysis of cell cycle distribution (n = 6). Data are presented as the mean ± SD, n = 3. *P < 0.05, **P < 0.01 compared with the corresponding control group by Student’s t-test.
