The effect of beta-xylosides on heparan sulfate synthesis by SV40-transformed Swiss mouse 3T3 cells. 1979

L S Johnston, and J M Keller

The medium and cell surface heparan sulfates isolated from SV40-transformed Swiss mouse 3T3 cells were examined in the presence and absence of 1.0 mM p-nitrophenyl-beta-D-xyloside. Incubation of the SV3T3 cells with this beta-xyloside resulted in: (a) a 4- to 5-fold reduction in the molecular weight distribution of medium heparan sulfate, (b) a 10-fold increase in the total synthesis of medium heparan sulfate, and (c) a small reduction in cell growth. There was little, if any, change in either the total level of synthesis or the molecular weight distribution of cell surface heparan sulfate. The covalent association of the beta-xyloside to the medium heparan sulfate was demonstrated by an analysis of the medium heparan sulfate produced by cells grown in the presence of [35S]sulfate and the fluorogenic beta-xyloside, 4-methylumbelliferyl-beta-D-xyloside. Treatment of the purified radiolabeled and fluorogenic heparan sulfate with either nitrous acid or heparitinase resulted in a decrease in the molecular weight of both radiolabeled and fluorogenic material. The data presented in this paper are discussed with respect to both the structure of heparan sulfate and the putative role of heparan sulfate in cell social behavior.

It is induced by infection with a transforming virus. Transformation, Viral Cell,Viral Cell Transformation,Cell Transformations, Viral,Transformations, Viral Cell,Viral Cell Transformations
D006025 Glycosaminoglycans Heteropolysaccharides which contain an N-acetylated hexosamine in a characteristic repeating disaccharide unit. The repeating structure of each disaccharide involves alternate 1,4- and 1,3-linkages consisting of either N-acetylglucosamine (see ACETYLGLUCOSAMINE) or N-acetylgalactosamine (see ACETYLGALACTOSAMINE). Glycosaminoglycan,Mucopolysaccharides
D006027 Glycosides Any compound that contains a constituent sugar, in which the hydroxyl group attached to the first carbon is substituted by an alcoholic, phenolic, or other group. They are named specifically for the sugar contained, such as glucoside (glucose), pentoside (pentose), fructoside (fructose), etc. Upon hydrolysis, a sugar and nonsugar component (aglycone) are formed.
