The analysis of MGAT3 promoter DNA methylation was performed in normal human ovarian surface epithelial cell lines (HOSE6-3 and HOSE17-1) and two serous ovarian cancer cell lines (OVCAR3 and A2780), showing low and high MGAT3 expression, respectively (Figure 2A). Here, MGAT3 is linked to ovarian serous adenocarcinoma.
