TLDR
Treatment of NP-C2 fibroblasts with exogenous recombinant HE1 protein ameliorated lysosomal accumulation of low density lipoprotein-derived cholesterol.Abstract:
Niemann-Pick type C2 disease (NP-C2) is a fatal hereditary disorder of unknown etiology characterized by defective egress of cholesterol from lysosomes. Here we show that the disease is caused by a deficiency in HE1, a ubiquitously expressed lysosomal protein identified previously as a cholesterol-binding protein. HE1 was undetectable in fibroblasts from NP-C2 patients but present in fibroblasts from unaffected controls and NP-C1 patients. Mutations in the HE1 gene, which maps to chromosome 14q24.3, were found in NP-C2 patients but not in controls. Treatment of NP-C2 fibroblasts with exogenous recombinant HE1 protein ameliorated lysosomal accumulation of low density lipoprotein-derived cholesterol.read more

Stimulation of mGluR1/5 Improves Defective Internalization of AMPA Receptors in NPC1 Mutant Mouse.
Xiao Feng,Fan Yang,Michael Rabenstein,Zhen Wang,Moritz J. Frech,Andreas Wree,Anja U Bräuer,Martin Witt,Anne Gläser,Andreas Hermann,Andreas Hermann,Arndt Rolfs,Jiankai Luo +12 more
TL;DR: The data imply that abnormal internalization of AMPA receptors is a critical mechanism for neuronal dysfunction and the correction of dysfunctional mGluR1/5 is a potential therapeutic strategy for NPC1 disease.

Niemann-Pick C2 Protein Expression Regulates Lithogenic Diet-Induced Gallstone Formation and Dietary Cholesterol Metabolism in Mice
Elisa Balboa,Gabriela Morales,Paula Aylwin,Gonzalo Carrasco,Ludwig Amigo,Juan Castro,Attilio Rigotti,Silvana Zanlungo +7 more
TL;DR: This work indicates that hepatic NPC2 expression is an important factor in the regulation of diet-derived cholesterol metabolism and disposal as well as in diet-induced cholesterol gallstone formation in mice.
The Neuropsychiatry of Hyperkinetic Movement Disorders: Insights from Neuroimaging into the Neural Circuit Bases of Dysfunction
Bradleigh D Hayhow,Islam Hassan,Jeffrey C.L. Looi,Francesco Gaillard,Dennis Velakoulis,Mark Walterfang +5 more
TL;DR: It is argued that neuropsychiatric symptoms are integral to a thorough phenomenological account of hyperkinetic movement disorders, and that these disorders can be conceptualized as disorders of complex subcortical networks with distinct functional architectures.
Regulation of vitamin E and the tocopherol transfer protein
TL;DR: The data suggests that TTP-expressing astrocytes distribute tocopherol to protect neurons from oxidative-stress induced damage, which is similar for other lipids, includingructose.

Two-dimensional complementary deoxyribonucleic acid electrophoresis revealing up-regulated human epididymal protein-1 and down-regulated CL-100 in thyroid papillary carcinoma
Jun-ichi Asakawa,Mieko Kodaira,Naofumi Ishikawa,Yuko Hirai,Shigenobu Nagataki,Farhad Moatamed,Masahiro Sugawara +6 more
TL;DR: It is shown that two-dimensional cDNA electrophoresis is a useful method of detecting differentially expressed genes in human diseases as demonstrated for HE-1 and CL-100 in papillary carcinoma.

Niemann–Pick C1 Is a Late Endosome-Resident Protein That Transiently Associates with Lysosomes and the Trans-Golgi Network
TL;DR: Characterizing the subcellular location of the NPC1 protein suggests that U18666A may inhibit the retrograde transport of NPC1 from lysosomes to late endosomes for subsequent transfer to the trans-Golgi network.
