Hypothesis-generating for sarcomere assembly in development; should not yet change clinical practice or guide human cardiac research.
Calcium transients regulate early steps in sarcomere formation, and myosin thick filament assembly depends heavily on intact actin and titin filament systems.
Li et al. (2003) studied Striated muscle development. Calcium transient blockers, MLCK inhibitors, and actin disrupting agents was evaluated on Patterned assembly of actin thin filaments, titin, capZ, and myosin. Blocking calcium transients compromises patterned assembly of actin thin filaments, titin, and capZ, indicating they regulate early steps in sarcomere formation during striated muscle development.
