Disease relevance of Phex

 

High impact information on Phex

  • IGF-I and GH stimulate Phex mRNA expression in lungs and bones and 1,25-dihydroxyvitamin D(3) production in hypophysectomized rats [2].
  • The mineralization-inhibiting protein osteopontin [3] abundant in the extracellular matrix of bone, and in tooth dentin and cementum, is a substrate for PHEX [4] [5]; PHEX essentially completely degrades inhibitory OPN [4].
 

Other interactions of Phex

  • CONCLUSIONS: Our findings suggest a coordinate regulation of Phex mRNA expression in lungs and bone and vitamin D metabolism during GH- and IGF-I-stimulated growth [2].
