Isoform Composition and Gene Expression of Thick and Thin Filament Proteins in Striated Muscles of Mice after 30-Day Space Flight

Figure 1

SDS-PAGE analysis of myosin heavy chains (MyHC) isoforms in striated muscles of control and flight mice. Percentage of I MyHC isoform in m. gastrocnemius of control and flight mice was 4.0 ± 1.5 and 1.55 ± 0.35 (), respectively. Percentage of IIA MyHC isoform in m. tibialis anterior of control and flight mice was and (, ), respectively.
