Outline of Final Research Achievements |
We clarified that ectopic calcium deposition is a cause of reduced bone mineral density in mice. We found that ectonucleotide pyrophosphatase/phosphodiesterase 1 (Enpp1), a single transmembrane molecule, plays an essential role in calcium deposition in bone, and that its dysfunction causes ectopic ossification and bone loss by using Enpp1-deficient (Enpp1 KO) mice. Furthermore, we found that Enpp1 is expressed primarily in articular chondrocytes and regulates systemic aging and ectopic calcification from articular cartilage.
