Among the 5 glycosyltransferases, only GnT-IVa expression was substantially increased in HCC tissues based on the pairwise comparison between individual HCC and paired adjacent normal tissue (p < 0.01) (Fig. 4A); the results of the other 4 glycosyltransferases are shown in Supplementary Figure S4. The gene discussed is MGAT4A; the disease is hepatocellular carcinoma.
