Project description:the goal of the study was to compare gene expression between control and Pbx1; Emx1-cre mutant corteces at e15.5 E15.5 whole cortex was dissected for the analysis. Control embryo genotype was Pbx1F/+. Mutant embryo genotype was Pbx1F/-; Emx1-cre. 4 corteces of each genotype were used for the analysis: 4 controls and 4 mutants, 8 samples total.

Project description:We investigates gene expression profiles in double conditional knockout mice for Sbno1 and Trp53. To generate these knockouts in the developing forebrain, Sbno1 floxed mice, Trp53 floxed mice, and the Emx1-Cre driver line were utilized. RNA-seq was performed on the telencephalon at embryonic day 12.5 (E12.5) and the cerebral cortex at embryonic day 18.5 (E18.5) to elucidate the roles of Sbno1 and Trp53 in neural development.
Project description:We demonstrate using conditional mutagenesis that Pbx1, with and without Pbx2+/ sensitization, regulates regional identity and laminar patterning of the developing mouse neocortex in cortical progenitors (Emx1-Cre) and in newly generated neurons (Nex1-Cre). Pbx1/2 mutants have three salient molecular phenotypes of cortical regional and laminar organization: hypoplasia of the frontal cortex, ventral expansion of the dorsomedial cortex, and ventral expansion of Reelin expression in the cortical plate of the frontal cortex, concomitant with an inversion of cortical layering in the rostral cortex. Molecular analyses, including PBX ChIP-seq, provide evidence that PBX promotes frontal cortex identity by repressing genes that promote dorsocaudal fate. Chromatin immunoprecipitation was performed using antibody against Pbx1/2/3/ (sc-888, Santa Cruz). Wild type E12.5 mouse whole cortex was used for the analysis.
