Subsequently, PCA was performed for a subset of key glycogens involved in the N-glycosylation pathway (MAN2A1, MAN2A2, MAN2B1, MAN2B2, MGAT1, MGAT2, MGAT3, MGAT5, MGAT5B, ST3GAL1, ST3GAL2, ST3GAL4, ST3GAL6, ST6GAL1, FUT2, FUT8) revealing a distinct glycogene expression profile in neoplasia patients when compared with healthy controls (Figure 1B). Here, ST3GAL2 is linked to neoplasm.
