Popis: | Hibernation is a biological phenomenon enabling animals to endure hypothermia. This study was designed to find the changes in myosin heavy chain (MHC) isoforms and their relationship to calcium sensitivity in frog ventricular muscle during hibernation. MHC profile was determined by SDS-4% polyacrylamide gel electrophoresis in active and hibernating frogs for different intervals of time (10, 20, 30, and 60 days). Calcium sensitivity of Triton-skinned ventricular muscle fiber bundles was determined. Compared with active and hibernated frogs for 10 and 20 days, hibernated frogs for 30 and 60 days expressed significant amount (p |
