We have previously reported that the elevated activities of serum alpha 1,3fucosyltransferase reverted to normal levels after curative removal of the tumors. To determine the origin of elevated serum alpha 1,3fucosyltransferase, blood samples were ob

Total syntheses of the GlyCAM-1 (glycosylation-dependent cell adhesion molecule-1) oligosaccharide structures: [alpha-NeuAc-(2 --3)-beta-Gal-(1 --4)-[alpha-Fuc-(1 --3)]-beta-(6-O-SO3Na)-GlcNAc-(1 --6)]-[alpha-NeuAc-(2 --3)-beta-Gal-(1 --3)]-alpha-Gal

A new ex vivo method for assaying adhesion of cancer cells to the greater omentum has been developed using mouse greater omentum and [3H]labelled human gastric and mouse colorectal cancer cells. Since the adhesion rates were found to increase up to 1

The syntheses of two sulfated pentasaccharides: beta-D-Gal6SO3Na-(1--3)-[beta-D-Gal-(1--4)-alpha-L-Fuc-(1--3)-beta-D-Glc-NAc-(1--6)]-alpha-D-GalNAc--OMe (1) and beta-D-Gal6SO3Na-(1--3)-[beta-D-Gal-(1--4)-alpha-L-Fuc-(1--3)-beta-D-Glc-NAc6SO3Na-(1--6)

The total syntheses of several complex oligosaccharide moieties that occur in the core structure of sulfated mucins are reported. A trisaccharide acceptor was obtained through regio- and stereoselective sialylation of methyl (6-O-pivaloyl-beta-D-gala

We found earlier in human breast and colon tumors, an augmented level of Gal : 3-O-sulfotransferase activities showing, respectively, an acceptor preference to blood group T-hapten (Group A enzymes) or Galbeta1,4GlcNAc (Group B enzymes) on the mucin

Our recent studies have revealed the existence of two distinct Gal: 3-O-sulfotransferases capable of acting on the C-3 position of galactose in a Core 2 branched structure, e.g., Galbeta1--4GlcNAcbeta1--6(Galbeta1--3)GalNacalph a1--OBenzyl as accepto

The carbohydrate-binding site of galectin 1, a vertebrate beta-galactoside-binding lectin, has a pronounced specificity for the betaGal(1--3)- and betaGal(1--4)GlcNAc sequences. The binding inhibition study reported herein was carried out to determin

The chemical synthesis of beta-D-Gal-(1--3)-6-O-SO3Na-beta-D-GlcNAc-(1--6)-alpha-D-Man-O-+ ++C6H4NO2 (1) and beta-D-Gal-(1--3)-6-O-SO3Na-beta-D-GlcNAc-(1--2)-alpha-D-Man-OMe (2) is reported using a key glycosyl donor, phenyl O-(2,3,4,6-tetra-O-acetyl
