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. The gene discussed is HEXB; the disease is ovarian carcinoma.
