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

Cloning and characterization of a shrimp ML superfamily protein
TL;DR: The cDNA and gene of an ML protein from an important white shrimp Litopenaeus vannamei is identified and it is suggested that the LvML may play roles in the shrimp innate immunity.

The role of lipids in atherogenesis
TL;DR: The role of oxysterols, triglycerides, fatty acids, and phospholips in atherogenesis are also described and modified of the lipid droplets fluidity by lipid composition is an important factor in susceptibility to this cholesterol efflux.

TL;DR: The utility of plasma chitotriosidase (ChT) and Chemokine (C–C motif) ligand 18 (CCL18)/pulmonary and activation-regulated chemokine(PARC) in conjunction with the NP-C suspicion index (NP-C SI) for guiding confirmatory laboratory testing in patients with suspected NP- C is assessed.

Somatic Cell Plasticity and Niemann-Pick Type C2 Protein FIBROBLAST ACTIVATION
TL;DR: It is shown that NPC2 deficiency in human fibroblasts confers their activation, and a novel mechanism where NPC2 by negatively regulating ERK 1/2 MAPK phosphorylation may efficiently suppress development of maladaptive tissue remodeling and inflammation is highlighted.

Computational analysis of human disease-associated genes and their protein products
TL;DR: Comparative genomics and sequence analysis are enabling us to identify counterparts of many human disease genes in model organisms, which should accelerate the pace of research and drug development to combat human diseases.
