Otx2 controls regional patterning within the MGE and regional identity of the septum [ChIP-Seq]

Project description:The Otx2 homeobox transcription factor is essential for gastrulation and early neural development. We generated Otx2 conditional knockout (cKO) mice to investigate its roles in telencephalon development after E9.0. We conducted transcriptional profiling and in situ hybridization to identify genes de-regulated in Otx2 cKO ventral forebrain. In parallel, we used ChIP-seq to identify enhancer elements, OTX2 binding motif, and which de-regulated genes are likely direct targets of Otx2 transcriptional regulation. We found that Otx2 was essential in septum specification; regulation of Fgf signaling in the rostral telencephalon; and medial ganglionic eminence (MGE) patterning, neurogenesis, and oligodendrogenesis. Within the MGE, Otx2 was required for ventral but not dorsal identity; this is the first demonstration of a transcription factor that contributes to regional patterning within the MGE. Microdissected subpallium (septum, MGE, and LGE ) from wildtype E12.5 CD-1 embryos was used in three independentanti-OTX2 ChIP-seq experiments.

Genome-wide distribution of Pbx1/2/3 in mouse cortex at embryonic day 12.5 [ChIP-seq]

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.

Otx2 binding to Nanog promoter protects embryonal stem cells from corruption of naive pluripotency and is required at morula stage for inner-cell mass differentiation of the epiblast

Project description:We have investigated the functional relevance of the transcriptional network controlled by the Otx2 binding activity in ESCs, EpiSCs and in vivo. In particular, to study the Otx2 transcriptional network we first performed Otx2 chromatin immunoprecipitation sequencing (ChIP-seq) experiments in wt ESCs and day 4 (d4) ESC-derived EpiSCs and employed as negative control ESCs and EpiSCs lacking Otx2. Moreover, to investigate the functional relevance of the Otx2 binding activity in pluripotent stem cells, we mutagenized in ESCs the Otx2 binding site located upstream of the Nanog TSS. To characterize the identity of ESCs and EpiSCs both lacking this Otx2 binding site, we analyzed their transcriptome by RNA-Seq.

Regulatory elements in a Transcriptional Network Orchestrating Regional Patterning of Cortical Progenitors

Project description:To map enhancers involved in regional patterning of cortical progenitors, we performed TF ChIP for patterning transcription factors as well as assays for epigenomic marks and DNA accessibility in VZ cells purified from wild-type and patterning mutant mice. This integrated approach identified a cortical Regionalization TF network and VZ enhancers involved in cortical regional patterning.
