Abstract:The changes of myosin isoform pattern and of its associated light chains in relation to the myosin ATPase profile were analysed in different muscles of the hypothyroidian amphibian Pleurodeles waltlii submitted to terrestrial stepping, using electrophoretic and histochemical techniques. These changes were specific to the muscle type but appeared globally characterized by a type-IIB to type-IIA/I fibre transition associated with a transition from fast to intermediate and/or slow myosin isoforms. These results a… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
