TLDR
The characterization of Gsh‐1, a novel murine homeobox gene, is reported, with a transcript of approximately 2 kb in size present at embryonic days 10.5 to E13.5 and the consensus DNA ninding site of the GSh‐1 homeoprotein is determined to be GCT/CA/CATTAG/A.
Abstract
We report the characterization of Gsh-1, a novel murine homeobox gene. Northern blot analysis revealed a transcript of approximately 2 kb in size present at embryonic days 10.5, 11.5, and 12.5 of development. The cDNA sequence encoded a proline rich motif, a polyalanine tract, and a homeodomain with strong homology to those encoded by the clustered Hox genes. The Gsh-1 expression pattern was determined for days E8.5 to E13.5 by whole mount and serial section in situ hybridizations. Gsh-1 transcription was restricted to the central nervous system. Expression is present in the neural tube and hindbrain as two continuous, bilaterally symmetrical stripes within neural epithelial tissue. In the mesencephalon, expression is seen as a band across the most anterior portion. There is also diencephalon expression in the anlagen of the thalamus and the hypothalamus as well as in the optic stalk, optic recess, and the ganglionic eminence. Moreover, through the use of fusion proteins containing the Gsh-1 homeodomain, we have determined the consensus DNA ninding site of the Gsh-1 homeoprotein to be GCT/CA/CATTAG/A. ©1995 Wiley-Liss, Inc.

Genetic Regulation of Vertebrate Forebrain Development by Homeobox Genes

TL;DR: This comprehensive review outlines the integral role of key homeobox transcription factors and their target genes on forebrain development, focused primarily on the telencephalon, and links of these transcription factors to human diseases, such as neurodevelopmental disorders and brain tumors.

Maintenance of neural stem cell regional identity in culture.

TL;DR: A V-SVZ monolayer culture system that retains regional gene expression and neurogenic potential of NSCs from the dorsal and ventral V-VZ retains key aspects of their in vivo regional identity in culture, providing new experimental opportunities for understanding how such developmental patterns are established and maintained during development.

TL;DR: A spatial Bayesian belief network model was developed to predict GBR-wide spatial distributions of allele frequencies at the antioxidant capacity locus C29226S281 and validated the two genetic markers as true quantitative trait loci for anti-oxidant capacity in the common coral, A. millepora.

A gene complex controlling segmentation in Drosophila.

TL;DR: The wild-type and mutant segmentation patterns are consistent with an antero-posterior gradient in repressor concentration along the embryo and a proximo-distal gradient along the chromosome in the affinities for repressor of each gene's cis-regulatory element.

Homeobox genes and axial patterning

TL;DR: Over the past seven years, the term “homeodomain” has evolved to define a class of protein domains that have recognizable similarity to a 60 amino acid motif originally recognized in three Drosophila homeotic and segmentation proteins.
