UCK2 and hepatocellular carcinoma: From GEPIA database, it was monitored that the expression of UCK2 was notably increased in HCC tissues (T, n = 369) compared with that in normal tissues (N, n = 160) (Fig. 4A), and the HCC patients with the high expression of UCK2 (n = 182) had the lower overall survival (P < 0.05) than low UCK2 group (n = 182) based on the median value of UCK2 (Fig. 4B).
