Muscle: the regulation of myogenesis.
The study of myogenesis in the embryo is a rapidly expanding field. In this context, the consequences of mutating different members of the MyoD family, together with an increasing number of observations that point to the importance of the MEF2 or RSRF family as myogenic regulators, and the identification of Pax-3 as a marker of early myogenic cells, have advanced our understanding of the molecular embryology of skeletal muscle. Novel cardiac regulatory factors such as Nkx-2.5 and GATA-4, in addition to MEF2 isoforms, are also beginning to be identified. At the molecular level, crystallographic studies have led to a structural model of the actinomyosin complex and also to information about how MyoD contacts DNA.
