In this article data implying that there are significant changes in glycoprotein synthesis
associated with malignant transformation and cellular differentiation are reviewed. This …

Glycosyltransferases, which are membrane-bound enzymes in the cell, are detected as
soluble activities in serum and other body fluids (Wagner and Cyn-kin, 1971; Kim et al …

Elevated levels of three plasma glycosyltransferases were associated with neoplasia in
cancer patients, notably those with tumor metastatic to liver. We examined levels of …

GDP‐fucose: N‐acetylglucosaminide α (1→ 3)‐L‐fucosyltransferase activity was measured
in sera of patients with various cancers using a synthetic substrate, N‐acetyl‐2′‐O …

In order to elucidate the mechanism of appearance of abnormal glycoproteins in cancer,
activities of glycoprotein glycosyltransferases and glycosidases were determined in the …

Several disease processes are characterized by alterations in the plasma levels of
glycoprotein substances.'-'Elevated circulating levels of these pro te in-ca rbohydrate …

Galactosyltransferase (GT) is reported to be a good marker for a number of malignancies.
Analytical and preparative attempts to characterize the more specific tumor-associated GT II …

Glycosyltransferase enzymes were measured in homogenates of normal and neoplastic
colon epithelium. The levels for exogenous galactosyltransferase and fucosyltransferase …

Three galactosyltransferases, an N-acetylgalactosaminyltransferase, two sialyltransferases,
