Normal human skin fibroblasts were grown in the presence of N-hexyl-O-glucosyl sphingosine (HGS), an inhibitor of aryl glucosidase and glucocerebrosidase. Tests of the cells with aryl glycosides showed that beta-glucosidase activity in the cells was drastically reduced while other enzyme activities (alpha-glucosidase, beta-galactosidase, and N-acetyl-beta-hexosaminidase) were normal or elevated. Exposure of cells to HGS for 28 days resulted in increased values for cell weight per plate, glucocerebroside concentration, and galactosyl-galactosylglucosyl ceramide concentration. The concentrations of total lipid, cholesterol, and protein were unchanged, as was the fatty acid distribution within the glycolipids. Chemically, the inhibitor-treated cells exhibited a model form of Gaucher's disease. Although many membranous cytoplasmic inclusions were induced by HGS, they were unlike the characteristic inclusions seen in individuals with the genetic disorder. Skin fibroblasts from a Gaucher patient showed no abnormalities in composition or appearance.
