LINC00152 could not recruit LSD1 to IL24 promoter. (a) LSD1 expression in A549 and SPCA1 cells transfected with si-LSD1. (b,c) qRT-PCR and western blotting were performed to detect the IL24 mRNA and protein level in A549 and SPCA1 cells. (d) ChIP-qRT-PCR of LSD1 occupancy and H3K4me2 binding in the IL24 promoter in A549 and SPCA1 cells treated with si-LINC00152(48h) or scrambled siRNA, IgG was used as a negative control. Values are shown as the mean Âą s.d in three independent experiments. *P
