Elevated activities of blood group Le gene dependent alpha(1----3)-L-fucosyltransferase in human saliva of Lewis negative patients with epithelial ovarian cancer. 1986

S Yazawa, and R Madiyalakan, and M S Piver, and K L Matta

Levels of alpha(1----3)-L-fucosyltransferase activities were measured in salivas of patients with ovarian cancer. GDP-L-Fuc:GlcNAc alpha(1----3)-fucosyltransferase was found elevated in patients known to have epithelial ovarian cancer, irrespective of their ABH and Lewis blood group phenotypes. GDP-L-Fuc: Glc alpha(1----3)-fucosyltransferase was also elevated in both Lewis positive and negative patients, although the enzyme activity was very low or absent in Lewis negative healthy controls.

UI MeSH Term Description Entries
D007983 Lewis Blood Group Antigens Carbohydrate antigens structurally related to the ABH BLOOD-GROUP SYSTEM. They may occur as a modification of saccharide chains on glycolipids or glycoproteins on cell surfaces or in plasma, or as free oligosaccharides in secretions. Lewis antigens are not synthesized in blood cells. Instead Lewis glycolipids present in plasma are absorbed onto the surface of ERYTHROCYTES; LYMPHOCYTES; and PLATELETS. The phenotypes Le(a) and Le(b) are the result of the actions of two genes the Le gene (fucosyltransferase FUT3) and the Se gene (fucosyltransferase FUT2) on the precursor carbohydrate, glycolipid or glycoprotein. Other FUCOSYLTRANSFERASES can also synthesize the Lewis antigens.

D005260 Female Females
D005647 Fucosyltransferases Enzymes catalyzing the transfer of fucose from a nucleoside diphosphate fucose to an acceptor molecule which is frequently another carbohydrate, a glycoprotein, or a glycolipid molecule. Elevated activity of some fucosyltransferases in human serum may serve as an indicator of malignancy. The class includes EC 2.4.1.65; EC 2.4.1.68; EC 2.4.1.69; EC 2.4.1.89. Fucosyltransferase
D006602 Hexosyltransferases Enzymes that catalyze the transfer of hexose groups. EC 2.4.1.-.
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D012463 Saliva The clear, viscous fluid secreted by the SALIVARY GLANDS and mucous glands of the mouth. It contains MUCINS, water, organic salts, and ptylin. Salivas
