  • Title: The presence of blood group A-active glycolipids in cancer tissues from blood group O patients.
    Author: Hattori H, Uemura K, Taketomi T.
    Journal: Biochim Biophys Acta; 1981 Dec 23; 666(3):361-9. PubMed ID: 6798995.
    Abstract:
    Glycolipids were isolated from human gastric cancer tissues and normal mucosae. Sulfogalactosylceramide, ganglioside and neutral glycolipid fractions were separated by DEAE-Sephadex and silica gel column chromatography. Sulfogalactosylceramide contents were higher in the cancer tissues than in the normal mucosae. Ganglioside contents showed considerable variations but in the cancer tissues in mole percentage of ganglioside GM3 was higher than in the normal mucosae. The cancer tissues contained more neutral glycolipids than normal tissues. Glycolipids of lacto-series, including fucolipids, were markedly increased in the cancer tissues. Blood group A-active glycolipids were found in the cancer tissues from two patients with blood group O but not found in the uninvolved tissue associated with the cancer tissue.
