In anticipation of seasonal climate changes, Siberian hamsters display a strategy for survival that entails profound physiological adaptations driven by photoperiod. These include weight loss, reproductive quiescence, and pelage growth with shortening photoperiod and vice versa with lengthening photoperiod. This study reports gene expression changes in the(More)
Neuromedin-U (NMU) has been reported to drive several physiological or behavioural responses following i.c.v. injection of the peptide into the third ventricle of rodent brains. Many of these responses are mediated through a change in corticotrophin-releasing factor (CRF) output from the paraventricular nucleus (PVN). A number of the physiological or(More)
To survive winter the Siberian hamster has evolved profound physiological and behavioral adaptations, including a moult to winter pelage, regression of the reproductive axis, onset of daily torpor and increased capacity for thermogenesis. However, one of the most striking adaptations is the catabolism of intraabdominal and sc fat reserves contributing to(More)
