[Myosin isoforms synthesized during regeneration of fast contraction skeletal muscle regeneration, in the presence of motor nerve and after denervation. Study in adult rats and mice].
Adult rat and mouse fast contracting skeletal muscles were injured by a cardiotoxin. New myosins of embryonic, neonatal and adult types appeared 4 and 5 days after the treatment in both innervated and denervated muscles. Although their structure remained altered, innervated--but not denervated--muscles rapidly recovered a normal isomyosin pattern.
