Priority Strategy of Intracellular Ca2+ Homeostasis in Skeletal Muscle Fibers during the Multiple Stresses of Hibernation
Intracellular calcium (Ca2+) homeostasis plays a vital role in the preservation of skeletal muscle.In view of the well-maintained skeletal muscle found in Daurian ground squirrels (Spermophilus dauricus) during hibernation, we hypothesized that hibernators possess unique strategies of intracellular Ca2+ homeostasis.Here, cytoplasmic, sarcoplasmic r
