Advances in the understanding of hypophosphatemic disorders have identified a novel group of molecules (FGF23, PHEX, MEPE, DMP1) that have been implicated in osteoblast mineralisation directly.The specific binding of PHEX to MEPE regulates the release of ASARM peptides which have an inhibitory role. Current concepts are speculative and the functional role of MEPE in chondrocyte mineralisation remains largely undefined.Proximal tibiae from 3-week old wild...

Intermittent PTH therapy is currently the only anabolic therapy for osteoporosis. As the mineralisation of the extracellular matrix of bone is essential for normal function it is vital that the effects of PTH on key regulators of mineralisation are uncovered. Ablation of Alpl, Phospho1 or Smpd3 results in skeletal hypomineralisation and as such this study examined the effects of bovine (b)PTH 1–34 on their expression. MC3T3 (clone-14) osteoblast-like cells display tempora...
