Abstract：
:Unlike rats, Siberian hamsters exhibit seasonal changes in energy balance that are controlled by the photoperiod (daylength). In Siberian hamsters, body weight and fat, and food intake peak in long, summer-like days and reach nadirs in short, winter-like days. The purpose of the present experiments was to test whether metabolic challenges that increase food intake in laboratory rats also increase feeding in Siberian hamsters. Specifically, we asked the questions: (a) Is food intake increased following a fast?; (b) Is food intake increased following treatments that block metabolic fuel utilization, such as the glucose utilization blocker 2-deoxy-D-glucose (2 DG), or that enhance storage of metabolic fuels, such as short acting insulin (regular insulin)?; (c) Does the combination of food deprivation and decreased metabolic fuel utilization increase food intake?; and (c) Does the photoperiod affect the feeding and physiological responses to metabolic challenges? Food intake was measured in response to fasting, insulin or 2 DG treatment in adult female Siberian hamsters housed in long photoperiods. Following exposure to a short photoperiod, these hamsters were tested for their response to insulin and 2 DG, but not to fasting. Food intake did not increase following fasts of 12, 24, or 48 h. Food intake was increased in long day-housed hamsters given the lowest dose of 2 DG tested (125 mg/kg) 2, 4, and 6 h after treatment, but not in short days nor in long days with larger doses of the 2 DG. Similarly, food intake was increased by treatment with regular insulin in long days, but not short days.(ABSTRACT TRUNCATED AT 250 WORDS)
