Otx2 controls regional patterning within the MGE and regional identity of the septum [Agilent]

ABSTRACT: 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.

Sp9 regulates medial ganglionic eminence-derived cortical interneuron development

Project description:In the mammalian cortex, about 60% of GABAergic interneurons, mainly including parvalbumin-expressing (PV+) and somatostatin (SST+) interneurons are generated from the medial ganglionic eminence (MGE) in the subpallium and tangentially migrate to the cortex. Here we analyze the role of the Sp9 transcription factor in regulating the development of MGE-derived cortical interneurons. We show that SP9 is widely expressed in the MGE subventricular zone (SVZ) and in MGE-derived migrating interneurons. By analyzing Sp9 null and conditional mutant mice, we demonstrate that Sp9 promotes MGE progenitor proliferation in the SVZ and is required for the normal patterning of tangential migration and the laminar distribution of MGE-derived cortical GABAergic interneurons. Loss of Sp9 function results in a ~50% reduction of MGE-derived cortical interneurons, an ectopic aggregation of MGE-derived neurons in the embryonic ventral telencephalon, and an increased ratio of SST+/PV+ cortical interneurons. Finally, we provide evidence that Sp9 regulates MGE derived cortical interneuron development through promoting expression of the Lhx6 and Lhx8 transcription factors.

Molecular programs of regional specification and neural stem cell fate progression in developing macaque telencephalon

Project description:During early telencephalic development, intricate processes of regional patterning and neural stem cell (NSC) fate specification take place. However, our understanding of these processes in primates, including both conserved and species-specific features, remains limited. Here, we profiled 761,529 single-cell transcriptomes from multiple regions of the prenatal macaque telencephalon. We deciphered the molecular programs of the early organizing centers and their cross-talk with NSCs, revealing primatebiased galanin-like peptide (GALP) signaling in the antero-ventral telencephalon. Regional transcriptomic variations were observed along the fronto-temporal axis during early stages of neocortical NSC progression and in neurons and astrocytes. Additionally, we found that genes associated with neuropsychiatric disorders and brain cancer risk might play critical roles in the early telencephalic organizers and during NSC progression.

Expression profiling of the Otx2 CKO retina

Project description:In the vertebrate retina, the Otx2 transcription factor plays a crucial role in the cell fate determination of both rod and cone photoreceptors. Otx2 conditional knockout (CKO) mice exhibited a total absence of rods and cones in the retina due to their cell fate conversion to amacrine-like cells. In order to investigate the entire transcriptome regulated by Otx2 in the developing retina, we performed microarray analysis on the Otx2 CKO retina. In order to clarify the molecular role of Otx2 in transcriptional regulation during development, we investigated the expression profile of the Otx2 CKO retina compared with that of the control retina with the genotype Otx2flox/flox;Crx-cre- using microarrays at two time points, P1 and P12.
