Project description:Pro-neural transcription factor Six3 has been implicated in neuronal differentiation. We established primary neural stem cell with Six3 overexpression, and utilized CUT&RUN to profile genomic loci bound by Six3.
Project description:Sox3 has been shown to be expressed within neural progenitors of the developing mouse central nervous system. However, identification of Sox3 targets within neural progenitors has remained elusive. Using microarrays we compared populations of in vitro derived mouse neural progenitor cells, with or without Sox3, to identify putative Sox3 neural progenitor targets.

However, identification of Sox3 targets within neural progenitors has remained elusive. Using microarrays we compared populations of in vitro derived mouse neural progenitor cells, with or without Sox3, to identify putative Sox3 neural progenitor targets. Mouse R1 ES cells, with or without Sox3, were differentiated into neural progenitor cells using the standard N2B27 protocols. At the fourth day of N2B27 differentiation, over two independent series, RNA was extracted from both Sox3 positive and Sox3 null populations and hybridization on a GeneChip Mouse Gene 1.0 ST Affymetrix microarrays.
Project description:D1- and D2-type medium spiny neurons (MSNs) are the principal projection neurons in the striatum, including in the dorsal striatum (caudate nucleus and putamen) and ventral striatum (nucleus accumbens and olfactory tubercle) that are generated by the lateral ganglionic eminence (LGE). Using conditional deletion, we show that mice lacking the Sp8 and Sp9 transcription factors (TFs) selectively have a severe reduction in D2 MSNs due to reduced neurogenesis in the LGE. Sp8/9 together drive expression of the Six3 TF in a spatial restricted domain of the LGE subventricular zone. Conditional deletion of Six3 also prevents the formation of most D2 MSNs, phenocopying the Sp8/9 loss of function. Finally, ChIP-Seq reveals that SP9 directly binds to the promoter and a putative enhancer of Six3. This study provides evidence for components of a transcription pathway, in a regionally restricted LGE domain, that selectively drives the generation of D2 MSNs.
