High impact information on Mvp

  • The low density lipoprotein receptor-related protein (LRP) is a large multifunctional clearance receptor that has been implicated in the hepatic uptake of chylomicron remnants and in the removal of protease-inhibitor complexes from the circulation and from the extracellular space [6].
  • Whereas LRP activity was normal, livers from treated mice incorporated significantly less sulfate into heparan sulfate proteoglycans (HSPG) than did controls [7].
  • Our results clearly demonstrate that two independent receptor systems, LRP and the mannose receptor, are involved in the hepatic clearance of t-PA [8].
  • Two distinct clearance mechanisms, which are mediated by the low density lipoprotein receptor-related protein (LRP) on liver parenchymal cells and by the mannose receptor on liver endothelial cells, have been described [8].
  • Using deletion constructs, the critical region in LRP that modulates APP processing was mapped to a seven peptide domain around the second NPXY domain (residues 4504-4510) [5].
 

Chemical compound and disease context of Mvp

 

Biological context of Mvp

 

Anatomical context of Mvp

  • Neither the MVP(-/-) embryonic stem cells nor the MVP(-/-) bone marrow cells showed an increased sensitivity to any of the drugs examined, as compared with wild-type cells [1].
  • There was no significant activation of either the MVP or VPARP promoters in drug-resistant cell lines in comparison to their parental, drug-sensitive counterparts [12].
  • We now demonstrate that binding of lactoferrin, Pseudomonas exotoxin A, and lipoprotein lipase to LRP on macrophages results in increased [Ca2+]i and inositol 1,4,5-triphosphate [13].
  • To investigate the intracellular pathway of the LRP signaling involved in neurite outgrowth, we tested the effects of alpha2M* on the phosphorylation of the mitogen-activated protein (MAP) extracellular signal-regulated kinases 1 and 2 (ERK1/2) [14].
  • Cs complexes do not stimulate neutrophil or monocytic chemotaxis but are removed by LRP, further underscoring its role as a serpin-enzyme complex clearance receptor [15].
 

Associations of Mvp with chemical compounds

  • In addition, MVP wild-type and deficient mice were treated with the anthracycline doxorubicin [1].
  • Furthermore, treatment with trichostatin A (TSA), a more specific inhibitor of HDAC, caused an increase in MVP protein, mRNA, and promoter activity [12].
  • The endocytic receptor protein LRP also mediates neuronal calcium signaling via N-methyl-D-aspartate receptors [16].
  • SECs were also degraded by HepG2 cells, and this process was inhibited by LRP antibodies, RAP, and chloroquine [17].
  • These studies are the first to identify a putative binding site in a serine protease inhibitor that is required for LRP-mediated internalization [18].
 

Other interactions of Mvp

  • To confirm a direct relation between vaults and multidrug resistance, and to investigate other possible functions of vaults, we have generated a major vault protein (MVP/lung resistance-related protein) knockout mouse model [1].
 

Analytical, diagnostic and therapeutic context of Mvp

  • Immunoprecipitation experiments corroborated these results showing co-precipitation of MVP and beta-tubulin [10].
  • Cryoelectron microscopy imaging of recombinant and tissue derived vaults: localization of the MVP N termini and VPARP [19].
  • To inhibit LRP, the 39-kD protein, which is a potent inhibitor of LRP activity, was overexpressed in the liver of mice using an adenoviral gene transfer technique [8].
  • The cell culture and in vivo experiments revealed that HSPGs are also involved in another, LRP-independent pathway of fVIII catabolism [20].
  • By immunoblotting of CNBr-digested LRP it is shown that Fab A8 binds to a fragment that harbors the second cluster of cysteine-rich complement-type repeats flanked by epidermal growth factor repeats [21].
