Hence, coupled with the new evidence from this study that the genes B4GALNT3 and B4GALNT4 are correlated with the presence of elevated LacdiNAc‐type N‐glycans on ovarian cancer tissue‐derived cell membranes, we subsequently evaluated the glycan profiles of these serous ovarian cancer cell lines, together with an additional ovarian cancer cell line (EFO27) (Fig. 6C). The gene discussed is B4GALNT3; the disease is ovarian serous adenocarcinoma.
