摘要：Environmental cues play important roles in the regulation of an animal's physiology and behaviour. The purpose of the present study was to test the hypothesis that ambient temperature was a cue to induce adjustments in body mass, body temperature and thermogenic capacity, associated with changes in serum leptin levels in the tree shrew (Tupaia belangeri chinensis). The results showed that the tree shrew increased resting metabolic rate (RMR), nonshivering thermogenesis (NST) and body mass when exposed to the cold. Uncoupling protein 1 (UCP1) content of brown adipose tissue (BAT) increased in the cold exposure. Also serum leptin levels were positively correlated with body mass. Together, these data supported our hypothesis that ambient temperature was a cue to induce changes in body mass and metabolism. Serum leptin participated in the regulation of energy balance and body weight in the tree shrew.
