| 中文摘要 | the present study was designed to examine whether photoperiod alone was effective to induce seasonal regulations in physiology in root voles (microtus oeconomus) from the qinghai-tibetan plateau noted for its extreme cold environment. root voles were randomly assigned into either long photoperiod (ld; 16l: 8d) or short photoperiod (sd; 8l: 16d) for 4 weeks at constant temperature (20 degrees c). at the end of acclimation, sd voles showed lower body mass and body fat coupled with higher energy intake than ld voles. sd greatly enhanced thermogenic capacities in root voles, as indicated by elevated basal metabolic rate (bmr), nonshivering thermogenesis (nst), mitochondrial protein content and uncoupling protein-1 (ucp1) content in brown adipose tissue (bat). although no variations in serum leptin levels were found between sd and ld voles, serum leptin levels were positively correlated with body mass and body fat mass, and negatively correlated with energy intake and ucp1 content in bat, respectively. to summarize, sd alone is effective in inducing higher thermogenic capacities and energy intake coupled with lower body mass and body fat mass in root voles. leptin is potentially involved in the photoperiod induced body mass regulation and thermogenesis in root voles.
