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.read more

Dissertation
A study of the generation of diversity in the central nervous system
TL;DR: It is shown, based on in vitro cultures as well as mutant analysis, that dorsal domains in the spinal cord can give rise to oligodendrocyte precursors and that these precursor have the capacity to develop to bona‐fide mature oligodendedrocytes based on expression of mature markers.
Dissertation
Direct programming of neural progenitors into medium spiny neurons by transcription factor transfection
TL;DR: This study showed that transfection of ISL1 enabled differentiation of neurons to produce a higher proportion of cells resembling MSNs, characterised by co-expression of the MSN markers DARPP32 and CTIP2 and expressing FOXP1.
The role of Gsx homeobox genes in the specification and differentiation of mouse lateral ganglionic eminence progenitors
TL;DR: This chapter describes the development and use of nanofiltration membranes for the recovery of phosphorous with a second type of technology called a “spatially aggregating substance” (“vessel”) and its applications in the coal industry.

Manipulating the mouse embryo: A laboratory manual
TL;DR: Here are recorded the tech- niques for preparing, inserting and analysing DNA sequences, for retroviral infection of mice, for production and use of EC and EK cells as vehicles for engineered sequences and for nuclear transplantation - all against a background of the basic procedures required for pro- ducing and handling the em- bryos.

An analysis of 5'-noncoding sequences from 699 vertebrate messenger RNAs
TL;DR: 5'-Noncoding sequences have been compiled from 699 vertebrate mRNAs and GCCA/GCCATGG emerges as the consensus sequence for initiation of translation in vertebrates.

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.

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.
