Researchers Uncover Molecular Mechanisms Behind Mammalian Hibernation
Source-GETTY-IMAGES Understanding Hibernation A recent study published in eLife sheds light on the intricate molecular mechanisms governing hibernation in mammals . Hibernation, a survival strategy adopted by numerous animals, involves a state of deep dormancy characterized by significant reductions in metabolic activity, body temperature, heart rate, and respiration. During this period, animals rely on stored energy reserves, particularly fats, to sustain their bodily functions amidst harsh environmental conditions and food scarcity during winter. Role of Myosin in Hibernation Researchers investigated the role of myosin , a motor protein involved in muscle contraction, in hibernation. They found that myosin plays a crucial role in non-shivering thermogenesis during hibernation, where heat is produced independently of muscle activity. Through a comprehensive analysis of skeletal muscle samples from both small and large hibernation in mammals, the team explored changes in myosin st...
