B4GALNT1 and hepatocellular carcinoma: To investigate the effects of B4GALNT1 upregulation on HCC progression, we performed several clinicopathological analysis, and observed that the upregulation of B4GALNT1 was associated with advanced T stage (p = 0.022), TNM stage (p = 0.030) (Table S1), and worse overall survival in both the TCGA-LIHC cohort (p = 0.035) and our cohort (p < 0.001) (Fig. 2a and b).
