Abstract

Non-shivering thermogenesis depends on expression of the uncoupling protein, UCP1, in brown adipose tissue (BAT). This is essential for preventing ruminant neonatal hypothermia, and its effects on energy balance may have implications for human obesity. In sheep, we have shown that there is an irreversible developmental loss of UCP1 after birth. This project aims to identify the molecular mechanisms responsible for the ontogenic programming of adipocyte function. We hypothesise that developmental control of BAT depends upon changes in the function of the peroxisome proliferator-activated receptor (PPAR) axis. We will establish the ontogenesis of PPAR axis gene expression in adipose tissue in vivo and in primary adipocyte cultures. Further in vitro experiments will examine how interactions between the PPAR axis and other regulatory inputs determine UCP1 inducibility.
