Abstract

4-Methylumbelliferyl-beta-D-xyloside (Xyl-MU) was added to the medium of cultured human skin fibroblasts. After incubation, the culture medium was pooled, and the Xyl-MU-induced oligosaccharides in the medium were purified by gel filtration chromatography. A novel Xyl-MU derivative was obtained, in addition to the previously reported Xyl-MU derivatives such as Gal-Gal-Xyl-MU, Gal-Xyl-MU, Sia-Gal-Xyl-MU, GlcA-Xyl-MU, and Xyl-Xyl-MU. The novel Xyl-MU derivative was purified using gel-filtration chromatography and high performance liquid chromatography and then subjected to carbohydrate composition analysis, enzymic digestion, Smith degradation, and ion spray mass spectrometric analysis. The results indicated that it was sulfate-O-3GlcA beta 1-4Xyl beta 1-MU. The structure of the nonreducing terminal of this Xyl-MU-induced oligosaccharide was the same as that of the oligosaccharide chain of a human peripheral nerve-derived glycolipid, reactive with the mouse monoclonal antibody HNK-1, and this Xyl-MU-induced oligosaccharide also reacted with HNK-1. These results suggest that the oligosaccharide, which is structurally identical to that of human peripheral nerve-derived glycolipid synthesized by nervous tissue and related to cell ad...Continue Reading

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function. Discover the latest research on adhesion molecule and their role in health and disease here.
