| Outline of Final Research Achievements |
Recent studies indicate that developmental genes are differentially expressed in subcutaneous adipose tissue (scWAT) and visceral adipose tissue (vWAT), and that some of these genes exhibit changes in expressions which closely correlate with the extent obesity and the pattern of fat distribution. The purpose of the current study was to investigate the effect of exercise training (TR) and high-fat diet (HFD) on developmental genes in three depots: inguinal, epididymal, and brown fat from rats. The fat depot-specific differences in mRNA levels of developmental genes were observed in three fat depots. TR and HFD induced the changes in the expression levels of some of these genes, i.e., HoxA5, HoxC9, and HoxC10. Moreover, the depression of HoxC10 in inguinal and brown adipocytes increases the expressions of brown fat genes, Ucp1 and Pgc1α. These data suggest that HoxC10 modulates adaptation of exercise training on adipose tissues.
