Increased cardiac myosin super-relaxation as an energy saving mechanism in hibernating grizzly bears

Increased cardiac myosin super-relaxation as an energy saving mechanism in hibernating grizzly bears

Aim: The aim of the present study was to define whether cardiac myosin contributes to energy conservation in the heart of hibernating mammals. Methods: Thin cardiac strips were isolated from the left ventricles of active and hibernating grizzly bears; and subjected to loaded Mant-ATP chase assays, X...
