Quantitative proteomics of human NPC1I1061T (sic) mutant fibroblasts provides insights into the pathogenesis of Niemann-Pick Type C disease.


ABSTRACT: Data from ProteomeXchange, PXD ID: PXD001938. Experiment: WTvsI1061T_TMT_inj01, file: folder summary. Published as part of Mol Cell Proteomics. 2015 Apr 14 . From the Abstract: {{i}} In our study, an isobaric labeling based quantitative analysis of proteome of NPC1I1061T (sic) primary fibroblasts when compared to wild-type cells identified 281 differentially expressed proteins based on stringent data analysis criteria. Gene ontology enrichment analysis revealed that these proteins play important roles in diverse cellular processes such as protein maturation, energy metabolism, metabolism of reactive oxygen species, antioxidant activity, steroid metabolism, lipid localization, and apoptosis. {{/i}} Cell types: GM18453 (NPC1:p.I1061T) and GM05659 (wt).

Niemann-Pick type C (NPC) disease is a fatal neurodegenerative disorder characterized by the accumulation of unesterified cholesterol in the late endosomal/lysosomal compartments. Mutations in the NPC1 protein are implicated in 95% of patients with NPC disease. The most prevalent mutation is the missense mutation I1061T that occurs in ∼ 15-20% of the disease alleles. In our study, an isobaric labeling-based quantitative analysis of proteome of NPC1(I1061T) primary fibroblasts when compared with  ...[more]
