Gaucher's disease, a lysosomal storage disorder caused by mutations in the gene encoding glucocerebrosidase (GCD), is currently treated by enzyme replacement therapy using recombinant GCD (Cerezyme) expressed in Chinese hamster ovary (CHO) cells. As complex glycans in mammalian cells do not terminate in mannose residues, which are essential for the(More)
Nuclear factor erythroid-2-related factor 2 (Nrf2) is a redox-sensitive transcription factor that regulates the expression of electrophile and xenobiotic detoxification enzymes and efflux proteins, which confer cytoprotection against oxidative stress and apoptosis in normal cells. Loss of function mutations in the Nrf2 inhibitor, Kelch-like ECH-associated(More)
Gaucher disease is an inherited metabolic disorder caused by mutations in the lysosomal enzyme acid-beta-glucosidase (GlcCerase). We recently determined the x-ray structure of GlcCerase to 2.0 A resolution (Dvir, H., Harel, M., McCarthy, A. A., Toker, L., Silman, I., Futerman, A. H., and Sussman, J. L. (2003) EMBO Rep.4, 704-709) and have now solved the(More)
In mammalian cells, glucosylceramide (GlcCer), the simplest glycosphingolipid, is hydrolyzed by the lysosomal enzyme acid beta-glucosidase (GlcCerase). In the human metabolic disorder Gaucher disease, GlcCerase activity is significantly decreased owing to one of approximately 200 mutations in the GlcCerase gene. The most common therapy for Gaucher disease(More)
Gaucher disease is an inherited metabolic disorder caused by mutations in the lysosomal enzyme acidglucosidase (GlcCerase). We recently determined the x-ray structure of GlcCerase to 2.0 Å resolution (Dvir, H., Harel, M., McCarthy, A. A., Toker, L., Silman, I., Futerman, A. H., and Sussman, J. L. (2003) EMBO Rep. 4, 704–709) and have now solved the(More)
Estrogen plays a key role in the development and progression of breast cancer; hence, antiestrogens, such as tamoxifen, have a marked impact on the treatment and outcome of breast cancer patients. Estrogen-induced growth requires continuous replenishment of energy, predominantly generated by glycolysis. Previous work from this laboratory demonstrated(More)
A new series of hybrid PDMP analogues, based both on PDMP and styryl analogues of natural ceramide, has been synthesized from D-serine. The synthetic route was developed such that future introduction of different aryl groups is straightforward. Biological evaluation, both in vitro on rat liver Golgi fractions as well as in HEK-293 and COS-7 cells, revealed(More)
