...John L. Rubenstein; Alex S. Nord; Marc Ekker ABSTRACT The vertebrate Dlx gene family encode homeobox transcription factors that are related to the Drosophila Distal-less ( Dll ) gene and are crucial for development. Over the last ∼35 years detailed information has accrued about the redundant...

...: The NS1 homeodomain transcription factor regulates lateral organ outgrowth from shoot meristems and leaf primordial margins by repressing the expression of negative growth regulators. Maize Leaf Narrow sheath Homeobox Margin Plant leaves are typically dorsiventrally flattened and broad...

Jones; Trevor Williams ABSTRACT The evolution of a hinged moveable jaw with variable morphology is considered a major factor behind the successful expansion of the vertebrates. DLX homeobox transcription factors are crucial for establishing the positional code...

... system. Homeodomain and basic helix-loop-helix transcription factors are required for retinogenesis, as well as patterning, differentiation and maintenance of specific retinal cell types. We hypothesized that Dlx1 , Dlx2 and Brn3b homeobox genes function in parallel intrinsic pathways to determine RGC...

... set of collaborating transcription factors. One of the collaborating transcription factors is the POU homeobox gene unc-86 , which collaborates with ttx-3 to determine the identity of the serotonergic NSM neurons. unc-86 in turn operates independently of ttx-3 in the anterior ganglion where...

...Joonsung Hwang; Taraneh Mehrani; Sarah E. Millar; Maria I. Morasso Dlx homeobox transcription factors regulate epidermal, neural and osteogenic cellular differentiation. Here, we demonstrate the central role of Dlx3 as a crucial transcriptional regulator of hair formation and regeneration...

... neuronal progenitors into multiple neuronal cell lineages. In the developing forebrain of mammals, the combined function of the Dlx1, Dlx2, Dlx5 and Dlx6 homeobox genes is necessary for the differentiation of the GABAergic interneurons born in the ventricular and subventricular zones of the ventral...

... tract (OFT)myocardium, revealed unexpected complexity in development of these muscle groups. The Pitx2 homeobox gene functions in both cranial paraxial mesoderm, to regulate eye muscle, and in splanchnic mesoderm to regulate OFT development. Here, we investigated Pitx2 in branchiomeric muscle. Pitx2...

... an unanticipated role for the enteric muscles in regulating this ultradian rhythm. Here we report our characterization of dsc-1 . We find that the dsc-1 mutants have a shortened defecation cycle length and are also expulsion defective. We cloned dsc-1 and found that it encodes a Paired-like homeobox...

Classical experiments showed the ability of retinoic acid (RA) to proximalize blastema positional values. Meis homeobox genes are involved in RA-dependent specification...

Eisenstat Dlx homeobox genes, the vertebrate homologs of Distal-less, play important roles in the development of the vertebrate forebrain, craniofacial structures and limbs. Members...

... epithelial regions are restricted to express region-specific subsets of OR genes. We show that progenitors and neurons express the LIM-homeobox gene Lhx2 and that neurons in Lhx2 -null mutant embryos do not diversify into subpopulations expressing different OR genes and other region-restricted genes...

The homeobox gene Hex is expressed in this endoderm cell domain and in the liver and ventral pancreas buds, after...
