Molecular signatures of mammalian hibernation: comparisons with alternative phenotypes
Abstract Background Mammalian hibernators display phenotypes similar to physiological responses to calorie restriction and fasting, sleep, cold exposure, and ischemia-reperfusion in non-hibernating species. Whether biochemical changes evident during hibernation have parallels in non-hibernating syst...
