XIST and colorectal carcinoma: Knockdown of lncRNA XIST could significantly increase the expression of miR-200b-3p level in CRC cell lines HCT116 (*P<0.05, Figure 5b), and ectopic expression of miR-200b-3p could obviously reduce the expression of lncRNA XIST, whereas inhibition of miR-200b-3p could increase the expression of lncRNA XIST in CRC cells (*P<0.05, Figure 5b).
