Glycolipid glycosyltransferase activities involved in the biosynthesis in vitro of neutral and acidic glycosphingolipids were measured in C-1300 tumors and cloned cells derived therefrom. An adrenergic clone (NIE-115) was grown in tissue culture in the presence of dibutyryl cyclic AMP and the levels of glycosyltransferases were measured before and after differentiation. Increased activities of galactosyltransferases and sialyl-transferases with a concomitant increase in glutamate decarboxylase activity (the enzyme that catalyzes the synthesis of an inhibitory neurotransmitter, γ-aminobutyric acid) were observed.
