XIST and hepatocellular carcinoma: Analogously, Liu and Xu (2019) also demonstrated that silencing lncRNA Xist, whose expression level is significantly higher in hepatocellular carcinoma tissue compared with adjacent tissues, inhibits cell growth and tumor formation in hepatocellular carcinoma by directly interacting with miR-200b-3p, but the downstream target gene of miR-200b-3p remains unclear.
