The imino sugar N-butyldeoxynojirimycin (NB-DNJ) exhibits anti-HIV activity in vitro and inhibits the purified glycoprocessing enzyme alpha 1,2-glucosidase I. It has been speculated that the anti-viral activity of this compound may result from inhibition of HIV envelope glycoprotein processing. However, structural evidence that glucosidase inhibition takes place in intact cells at the anti-vira...
BACKGROUND Clinical features, complications and treatments of Gaucher's disease (GD), a rare autosomal-recessive disorder due to a confirmed lysosomal enzyme (glucocerebrosidase) deficiency, are described. METHODS All patients with known GD, living in France, with ≥ 1 consultations (1980-2010), were included in the French GD registry, yielding the following 4 groups: the entire cohort, with c...
BACKGROUND Niemann-Pick type C (NPC) disease is a fatal neurodegenerative disorder caused most commonly by a defect in the NPC1 protein and characterized by widespread intracellular accumulation of unesterified cholesterol and glycosphingolipids (GSLs). While current treatment therapies are limited, a few drugs tested in Npc1(-/-) mice have shown partial benefit. During a combination treatment ...
tables on cholesterol by using its oxidation products to diagnose and treat the disease in its earliest stages. drug efficacy. Free cholesterol may be at the root of Niemann-Pick C1 disease, but now, there is a way to turn the markers of early clinical disease and can be used not only to monitor disease progression but also to demonstrate or diabetes. Together, these compelling results suggest ...
Niemann-Pick disease type C (NP-C) is a rare, progressive, irreversible disease leading to disabling neurological manifestations and premature death. The estimated disease incidence is 1:120,000 live births, but this likely represents an underestimate, as the disease may be under-diagnosed due to its highly heterogeneous presentation. NP-C is characterised by visceral, neurological and psychiat...
A mammalian N-acetylglucosamine (GlcNAc) transferase I (GnT I)-independent fucosylation pathway is revealed by the use of matrix-assisted laser desorption/ionization (MALDI) and negative-ion nano-electrospray ionization (ESI) mass spectrometry of N-linked glycans from natively folded recombinant glycoproteins, expressed in both human embryonic kidney (HEK) 293S and Chinese hamster ovary (CHO) L...
A series of novel polyurethanes containing cross-linked siloxane in the side chain (SPU) were successfully synthesized through a sol-gel process. The SPU was composed of 0%-20% N-(n-butyl)-3-aminopropyltriethoxysilane (HDI-T) modified hexamethylene diisocynate homopolymer. The effects of HDI-T content on both the structure and properties of SPU were investigated by Fourier transform infrared sp...
Glycosphingolipids (GSLs) are essential constituents of cell membranes and lipid rafts and can modulate signal transduction events. The contribution of GSLs in osteoclast (OC) activation and osteolytic bone diseases in malignancies such as the plasma cell dyscrasia multiple myeloma (MM) is not known. Here, we tested the hypothesis that pathological activation of OCs in MM requires de novo GSL s...
Gangliosides are sialic acid-containing glycosphingolipids that have long been associated with tumor malignancy and metastasis. Mounting evidence suggests that gangliosides also modulate tumor angiogenesis. Tumor cells shed gangliosides into the microenvironment, which produces both autocrine and paracrine effects on tumor cells and tumor-associated host cells. In this study, we show that the s...
Journal of Lipid Research Volume 55, 2014 993 Copyright © 2014 by the American Society for Biochemistry and Molecular Biology, Inc. The identifi cation of the lysosome as a unique cellular organelle by Christian de Duve ( 1 ) occurred less than sixty years ago. The importance of his discovery was immediately appreciated when several monogenic diseases arising from the loss of lysosomal enzyme a...
