| Outline of Final Research Achievements |
Vascular calcification is a risk factor for cardiovascular events in chronic kidney disease (CKD) patients. In order to develop nutritional therapy for suppressing vascular calcification, we examined to clarify the phosphate regulation by bone-vessel interaction. In this study, we searched candidate molecule that function in phosphate regulation in both bone and vessel and then we analyzed the function in vitro and in vivo. The candidate molecule expression increased after differentiation of osteoclasts and calcification of vascular smooth muscle cells. In CKD model rat, the candidate molecule expressed at calcification area in vascular aorta. Thus, it was indicated that this molecule is likely to be involved in calcification. We will further research the function and relation with nutrition in the future, and will lead to the developing of nutrition therapy.
