It should also be noted that a recent study by Mehta et al. observed a similar level of core fucosylation in HCC tissue compared to the adjacent nontumor tissue, after measuring increased expression level of FUT8 in HCC tissue compared to nontumor tissue, suggesting that there might be an abnormal secretion of core fucosylated proteins into the serum of HCC patients [25]. The gene discussed is FUT8; the disease is hepatocellular carcinoma.
