One branch clustered eight genes (NAGA, B4GALT6, HEXA, GLB1, GBA, GLA, UGCG, HEXB) with generally comparable expression levels among the cell lines, except for the UGCG gene which was expressed at considerably higher levels in both HOSE cell lines compared with the ovarian cancer cell lines. This evidence concerns the gene B4GALT6 and ovarian cancer.
