Glycosyltransferase activities were measured in normal monocytes and in leukaemic monoblasts. Biosynthesis of glycosylated derivatives of dolichyl-monophosphate, which act as intermediates in glycosylation, was measured. Transfer of mannose from GDP-mannose was greatly increased in leukaemic monoblasts. Galactosyltransferase activities, using endogenous protein acceptors, were increased in leukaemic cells of the monocytic lineage compared to normal cells. No significant difference was observed on specific exogenous glycoprotein acceptors. These selective increases of some glycosyltransferase activities in normal and leukaemic monocytic cells can be correlated either with different expression of specific carbohydrate structures or with changes in glycosylation regulation.

D012799 Sialyltransferases A group of enzymes with the general activity CMP-N-acetylneuraminate:acceptor N-acetylneuraminyl transferase. They catalyze the transfer of N-ACETYLNEURAMINIC ACID from CMP-N-ACETYLNEURAMINIC ACID to an acceptor, which is usually the terminal sugar residue of an oligosaccharide, a glycoprotein, or a glycolipid.

D014408 Biomarkers, Tumor Molecular products metabolized and secreted by neoplastic tissue and characterized biochemically in cells or BODY FLUIDS. They are indicators of tumor stage and grade as well as useful for monitoring responses to treatment and predicting recurrence. Many chemical groups are represented including HORMONES; ANTIGENS; amino and NUCLEIC ACIDS; ENZYMES; POLYAMINES; and specific CELL MEMBRANE PROTEINS and LIPIDS.
