| Outline of Final Research Achievements |
Adiponectin (Adp) protein was detected in murine aorta, heart, and skeletal muscle. In the atherosclerotic lesion, Adp was detected in endothelial cells, synthetic smooth muscle cells and monocytes attaching to endothelial cells. Tissue accumulation of Adp was reduced in T-cadherin knockout mice while plasma Adp level significantly increased compared to control. Accumulation and function of Adp exerted through T-cadherin. ELISA system to measure C1q- Adp complex was established, and circulating levels of complex were associated with body mass index, visceral and subcutaneous fat area, and atherosclerosis. Adp possessed an anti-fibrotic effect of heart partly through the suppression of beta-catenin pathway. We generated Favine (Fav) knockout mice. Adipose tissue and body weight were significantly less in Fav-KO mice than control. It was revealed that Fav has both adipogenic and lipogenic effects on adipocytes.
