Disease relevance of Enpp1

 

High impact information on Enpp1

  • Mutation in Npps in a mouse model of ossification of the posterior longitudinal ligament of the spine [5].
  • Using a positional candidate-gene approach, we determined the ttw phenotype is caused by a nonsense mutation (glycine 568 to stop) in the Npps gene which encodes nucleotide pyrophosphatase [5].
  • Cultured Cst10-/- chondrocytes showed a reduction in calcification with activation of an SRY site in the promoter of the gene encoding nucleotide pyrophosphatase phosphodiesterase 1 (NPP1, encoded by Enpp1) [6].
  • Each allele of Akp2 and Enpp1 has a measurable influence on mineralization status in vivo [2].
  • Two osteoblast proteins, tissue-nonspecific alkaline phosphatase (TNAP) and plasma cell membrane glycoprotein-1 (PC-1) are involved in this process [2].
 

Chemical compound and disease context of Enpp1

  • Neuroendocrine (NE) cells may be involved not only in growth and differentiation of the normal prostate but also in carcinogenesis and progression of prostate adenocarcinoma (Pca), including development of androgen resistance [7].

Associations of Enpp1 with chemical compounds

 

Regulatory relationships of Enpp1

  • FGF2 specifically induced expression of PC-1 and ANK while inhibiting expression of TNAP, at both mRNA and protein levels [15].
 

Other interactions of Enpp1

  • The assessments of insulin, PC-1 and PC-2 mRNAs of the grafts suggest that the iNOS-/- islets may be more resistant to destruction in the transplantation model used; however, this was not sufficient to prolong the period of normoglycemia posttransplantation [16].
  • Mouse mutant ttw (tiptoe walking) is an excellent model for ectopic ossification [17].
  • Linked deficiencies in extracellular PP(i) and osteopontin mediate pathologic calcification associated with defective PC-1 and ANK expression [4].
  • Here, we report a novel allele of mouse Pc1 (N222D) that leads to obesity, abnormal proinsulin processing and multiple endocrinological defects [18].
  • It is suggested that the PC-1 protein and the transferrin receptor may have had a common evolutionary origin, and may have similar functions [14].
