Project description:Sequencing of the mouse ventral rhombomere 1 tissues and cells to characterize the Tal1-dependent and -independent neuronal precursor groups. The data allowed to describe the cell types in the R1 brain region, and map gene expression dynamics during bifurcation of the GABAergic and glutamatergic lineages. Our results provide a framework for understanding the development of cellular diversity in the tegmental nuclei.

Project description:During development, rhombomere 1 gives rise to a multitude of cell types, including serotonergic as well as glutamatergic neurons that populate the raphe nuclei. Transcription factor Gata2 has been shown to regulate the development of the serotonergic neurons in the rhombomere 1. To further understand the role and targets of Gata2 in the rhombomere 1 during development, we used cDNA microarrays to compare gene expression in the embryonic day 12.5 (E12.5) rhombomere 1 tissues extracted from wild-type and Gata2 mutant embryos.

Project description:This study analyzed mRNA profiles in rhombomere 4 of E10.5 mouse knock-in embryos expressing either normal endogenous Hox-B1 protein or the paralogous Hox-A1 protein from the Hoxb1 locus. The Hox-A1 protein was found to be detectably less efficacious than Hox-B1 in promoting neurogenesis in the basal plate of rhombomere 4 and its transcriptional profile shared several similarities with the Hoxb1 mutant. Experiment Overall Design: GFP-positive cells were FACS-sorted from dissected hindbrains of entire litters of E10.5 mouse embryos expressing either normal endogenous Hox-B1 protein or the paralogous Hox-A1 protein from the Hoxb1 locus, either one tagged with IRES-tauGFP. Three independent biological replicates of each genotype were analyzed. Total RNA was isolated, amplified and hybridized to Affymetrix Mouse Genome 430 2.0 Arrays.
