Specification of jaw identity by the Hand2 transcription factor
Acquisition of the lower jaw (mandible) was evolutionarily important for jawed vertebrates. In humans, syndromic craniofacial malformations often accompany jaw anomalies. The basic helix-loop-helix transcription factor Hand2, which is conserved among jawed vertebrates, is expressed in the neural crest in the mandibular process but not in the maxillary process of the first branchial arch. Here, ...
متن کاملGenetic and comparative mapping of genes dysregulated in mouse hearts lacking the Hand2 transcription factor gene.
The helix-loop-helix transcription factor HAND2 plays a vital role in the development of the heart, limb, facies, and other neural crest-derived structures. We used differential display analysis to identify 33 putative HAND2-regulated ESTs that are differentially expressed in Hand2(-/-) vs wild-type mice. We determined the positions on mouse and human genetic maps of 29 of these by using the T3...
متن کاملThe bHLH transcription factor hand2 plays parallel roles in zebrafish heart and pectoral fin development.
The precursors of several organs reside within the lateral plate mesoderm of vertebrate embryos. Here, we demonstrate that the zebrafish hands off locus is essential for the development of two structures derived from the lateral plate mesoderm - the heart and the pectoral fin. hands off mutant embryos have defects in myocardial development from an early stage: they produce a reduced number of m...
متن کاملDNA binding-dependent and -independent functions of the Hand2 transcription factor during mouse embryogenesis.
The basic helix-loop-helix (bHLH) transcription factor Hand2 is required for growth and development of the heart, branchial arches and limb buds. To determine whether DNA binding is required for Hand2 to regulate the growth and development of these different embryonic tissues, we generated mutant mice in which the Hand2 locus was modified by a mutation (referred to as Hand2(EDE)) that abolished...
متن کاملLaminar Organization of Cerebral Cortex in Transforming Growth Factor Beta Mutant Mice
Transforming growth factor betas (TGF?s) are one of the most widespread and versatile cytokines. The three mammalian TGF? isoforms, ?1, ?2, and ?3, and their receptors regulate proliferation of neuronal precursors as well as survival and differentiation in neurons of developing and adult nervous system. Functions of TGF?s has a wide spectrum ranging from regulating cell proliferation and differ...
