Hormonal controls of obesity in feeding and fasting hibernating mammals
MetadataShow full item record
Mammals that hibernate (hibernators) are intriguing models for the study of controls of food intake and adiposity due to their robust circannual cycle of obesity and anorexia. The pathways controlling these cycles in hibernators have not been fully elucidated. In order to clarify the relationships between various hormones, enzymes and metabolic factors, I examined endogenous and experimentally manipulated levels of several factors in hibernators kept under various physiological conditions, including short-term fasting in summer, long-term fasting in winter, and at low and high body temperature. ...
