FUT8 and Familial prostate cancer: In additional cohorts of patients with prostate cancer, FUT8 mRNA was upregulated in prostate cancers with a ‘metastatic’ signature compared to tumours with ‘non‐metastatic’ biology [67] (n20, p < 0.05) (Figure 1C) and in metastatic prostate tumours compared to localised disease (n = 20, p < 0.05) (Figure 1D).
