描述 | Gaucher disease (GD) is an inherited lipidstorage disorder caused by deficiency of glucocerebrosidase (GlcCerase) activity and characterized by intralysosomal accumulation of glucocerebroside (glucosylceramide; GlcCer) that leads to dysfunction in multiple organ systems. Miglustat is an iminosugar that reversibly inhibits glucosylceramide synthase and reduces GlcCer biosynthesis[3]. The addition of 10 μM miglustat to COS-7 cell medium leads to 1.3-, 2.1-, 2.3-, 3.6-, and 9.9-fold increase in the activity of S364R, wild-type, N370S, V15M, and M123T GC (β-glucosidase), respectively. These results suggest that miglustat, in addition to the inhibitory effect on CSG (glucosyltransferase), also works as a "chemical chaperone", increasing the activity of acid beta-glucosidase of wild-type and several GC mutated proteins, including the most frequent N370S mutation[4]. | ||
