Transcription Factors Sp8 and Sp9 Coordinately Regulate Olfactory Bulb Interneuron Development [ChIP-Seq]

ABSTRACT: We conducted RNA-Seq and in situ hybridization to identify transcriptional profile changes in the Sp8/Sp9-DCKO olfactory bulb. Simultaneously, we did ChIP-Seq with homemade Sp9 antibody to identify Sp9 binding motifs and which changed genes might be the direct targets of transcription factor Sp9. We found that Sp9 directly binded to key genes which are required for olfactory bulb development. Transcription factors Sp8 and Sp9 belong to the same transcription factor family, so we think Sp8 and Sp9 have very similar binding sites of transcriptional regulation.

Transcription Factors Sp8 and Sp9 Coordinately Regulate Olfactory Bulb Interneuron Development [RNA-Seq]

Project description:Purpose: To asses changes in gene expression profiles from the P11 no cre littermate control olfactory bulbs and conditional double knockout olfactory bulbs of Dlx5/6-CIE; Sp8 Flox/Flox; Sp9 Flox/Flox (Sp8/Sp9-DCKO) mice. Methods: Total RNA was isolated and sequenced from the olfactory bulbs of the P11 no cre littermate controls or Sp8/Sp9-DCKO mice in duplicate using an illumina high-seq 2500. Raw data was analyzed using TopHat. Genes were considered changed which performed fold-change>=2 and FDR<=0.05. Changed genes were then filtered to reveal the downstream targets of Sp8 and Sp9. Results: 32 genes were significantly increased and 144 genes were significantly decreased in expression level due to the loss of Sp9 and Sp8 expression.

Transcription Factors Sp8 and Sp9 Coordinately Regulate Olfactory Bulb Interneuron Development [RNA-seq 2]

Project description:Purpose: To asses changes in gene expression profiles from the P30 wild type littermate control olfactory bulbs and conditional double knockout olfactory bulbs of hGFAP-Cre; Sp8 Flox/Flox; Sp9 Flox/Flox mice. Methods: Total RNA was isolated and sequenced from the olfactory bulbs of the P30 wild type littermate controls or hGFAP-Cre; Sp8 Flox/Flox; Sp9 Flox/Flox mice in tetrad using an illumina high-seq 2500. Raw data was analyzed using TopHat. Genes were considered changed which performed fold-change>=2 and FDR<=0.05. Changed genes were then filtered to reveal the downstream targets of Sp8 and Sp9. Results: 31 genes were significantly increased and 74 genes were significantly decreased in expression level due to the loss of Sp9 and Sp8 expression.

Sp8 and Sp9 Coordinately Promote Striatal Medium Spiny Neuron Production through Activating Six3 Expression [RNA-seq]

Project description:Purpose: To assess changes in gene expression profiles from the E16.5 no cre littermate control striatum and conditional double knockout of Dlx5/6-CIE; Sp8 Flox/Flox; Sp9 Flox/Flox mice. Methods: Total RNA was isolated and sequenced from the striatum of the E16.5 no cre littermate control or Dlx5/6-CIE; Sp8 Flox/Flox; Sp9 Flox/Flox mice in duplicate using an illumina high-seq 2500. Raw data was analyzed using TopHat. Genes were considered changed which performed fold-change>=2 and FDR<=0.05. Changed genes were then filtered to reveal the downstream targets of Sp8 and Sp9. Results: 80 genes were significantly increased and 120 genes were significantly decreased in expression level due to the loss of Sp8 and Sp9 expression.

Sp8 and Sp9 coordinately promote D2-type medium spiny neuron production by activating Six3 expression [ChIP-Seq]

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.
