In addition, the relationship between cytosine methylation in CpG island 2 of the MGAT3 gene promoter, its expression and the presence of bisecting GlcNAc on N-glycans in ovarian cancer cell lines were already demonstrated, although the methylation change was obtained using 5-aza-deoxycitidine treatment (41). Here, MGAT3 is linked to ovarian carcinoma.
