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.
