anti-Niemann-Pick Disease, Type C1 (NPC1) Antikörper

Zebrafish Niemann-Pick Disease, Type C1 (NPC1) Interaktionspartner

1. this is the first report, showing a role of NPC1 in platelet function and formation but further studies are needed to define how cholesterol storage interferes with these processes

2. npc1 is required early for proper cell movement and cholesterol localization and later for cell survival

Rabbit Niemann-Pick Disease, Type C1 (NPC1) Interaktionspartner

1. Availability of assays to measure NPC1 binding to membrne proteins may further the understanding of ways in which oxysterols regulate intracellular lipid transport.

Mouse (Murine) Niemann-Pick Disease, Type C1 (NPC1) Interaktionspartner

1. This study shown Microglia can aggravate olfactory dysfunction by mediating neuronal death in the olfactory bulb (OB) of a murine model of Niemann-Pick disease type C1 (NPC1)

2. High-resolution respirometry analyses revealed that GSH-EE improved oxidative phosphorylation, coupled respiration and maximal electron transfer in cerebellum of Npc1(-/-) mice

3. Lysosomal oxLDL accumulation within macrophages contributes to murine atherosclerosis. Prevention of oxLDL uptake leads to decreased atherosclerosis in hematopoietic NPC1-deficient Ldlr (zeige LDLR Antikörper)(-/-) mice

4. the spleen is significantly enlarged in Npc1(-/-) mice.

5. Study is the first data to reveal motor and behavioral deficits in early maturity of Npc1+/- mice.

6. Npc1 gene interacts with a high fat diet to promote weight gain through differential regulation of central energy metabolism pathways.

7. AAV9-mediated NPC1 delivery significantly promoted Purkinje cell survival, restored locomotor activity and coordination, and increased the lifespan of NPC1(-/-) mice. Our work suggests that AAV-based gene therapy is a promising means to treat NPC disease.

8. Here, we identify lamellar inclusions as the subcellular site of lipid accumulation in neurons, we uncover a vicious cycle of cholesterol synthesis and accretion, which may cause gradual neurodegeneration, and we reveal how beta-cyclodextrin, a potential therapeutic drug, reverts these changes. Our study provides new mechanistic insight in NPC disease and uncovers new targets for therapeutic approaches.

9. Male NPC1+/- mice had increased fat storage while eating a high-fat diet.

10. Our data show that: i) HDAC2 (zeige HDAC2 Antikörper) levels and activity are increased in NPC neuronal models and in Npc1(-/-) mice; ii) inhibition of c-Abl (zeige ABL1 Antikörper) or c-Abl (zeige ABL1 Antikörper) deficiency prevents the increase of HDAC2 (zeige HDAC2 Antikörper) protein levels and activity in NPC neuronal models

Human Niemann-Pick Disease, Type C1 (NPC1) Interaktionspartner

1. This study demonistrated that heterozygous mutations of NPC1 genes could contribute to dementia plus, at least in a subset of patients.

2. Docking of the NPC1-NPC2 (zeige NPC2 Antikörper) complex onto the full-length NPC1 structure reveals a direct cholesterol transfer tunnel between NPC2 (zeige NPC2 Antikörper) and N-terminal domain cholesterol binding pockets, supporting the "hydrophobic hand-off" cholesterol transfer model.

3. Taken together, these studies suggest that Ebola virus requires phosphatidylinositol (3,5) bisphosphate production in cells to promote efficient delivery to NPC1.

4. identification of NPC1 and/or NPC2 (zeige NPC2 Antikörper) mutations combined with descriptions of clinical phenotype, will improve our knowledge of pathogenic mutations and our understanding of genotype-phenotype correlations.

5. Here we report a crystal structure of a large fragment of human NPC1 at 3.6 A resolution, which reveals internal twofold pseudosymmetry along TM 2 (zeige TPM2 Antikörper)-13 and two structurally homologous domains that protrude 60 A into the endosomal lumen, and we propose a model for NPC1 function in cholesterol sensing and transport.

6. Sequencing of genomic DNA from GM03123 Led to the identification of a mutation in NPC1 GENE, g.41940G>C (c.1947 + 5G>C; rs770321568) (Fig. 1A), with a minor allele frequency of 0.0000082

7. We identified major events in NPC1 evolution and revealed and compared orthologs and paralogs of the human NPC1 gene through phylogenetic and protein sequence analyses. We predicted whether an amino acid substitution affects protein function by reducing the organism's fitness.

8. The mutant NPC1 did not significantly reduce cholesterol accumulation, but approximately 85% of the mutants showed reduced cholesterol accumulation when treated with vorinostat or panobinostat.

9. knockdown of TMEM97 (zeige TMEM97 Antikörper) also increases levels of residual NPC1 in NPC1-mutant patient fibroblasts and reduces cholesterol storage in an NPC1-dependent manner. Our findings propose TMEM97 (zeige TMEM97 Antikörper) inhibition as a novel strategy to increase residual NPC1 levels in cells and a potential therapeutic target for Niemann-Pick type C disease (NP-C).

10. Rare loss-of-function NPC1 mutations were identified as being associated with human adiposity with a high penetrance in a Chinese population.
