  • Title: Transient expression of wild-type and mutant glucocerebrosidases in hybrid vaccinia expression system.
    Author: Hodanová K, Melková Z, Horowitz M, Hrebícek M.
    Journal: Eur J Hum Genet; 2003 May; 11(5):369-74. PubMed ID: 12734541.
    Abstract:
    Gaucher disease, the most prevalent lysosomal storage disease, is characterised by a significant phenotypic variation caused by more than 150 mutations. In order to verify pathogenicity of mutations found in the Czech Gaucher population, the vaccinia expression system was used. The wild-type human beta-glucocerebrosidase cDNA and cDNAs carrying the mutations 72delC, 1326insT, 1263del55, S196P, N370S, L444P, G202E, D409H, T369M, L444P+V460V, and D409H+T369M were expressed in Gaucher fibroblast cell line (L444P/S107L), BSC40, and HeLa G cells. The enzymatic activity and immunological reactivity were analysed. Only beta-glucocerebrosidase-deficient fibroblasts were suitable for expression using plasmid transfection. The expressed beta-glucosidase activity of mutant glucocerebrosidases was in good correlation with the presumed severity of the mutations.
