TCF20 regulates neurogenesis in mice brain

ABSTRACT: Purpose:To gain a deeper insight into how TCF20 regulates neurogenesis in mice brain, RNA-sequencing (RNA-seq) was performed to analyze the genome-wide changes by TCF20 deletion at E13.5. Methods: Total RNA was extracted from E13.5 telencephalic tissue of TCF20 WT HET KO mice. Then total RNA was quality controlled and quantified using an Agilent 2100 Bioanalyzer. After converting to cDNA and building library, high-throughput sequencing was performed using the Illumina HiSeq 2500 platform in Annoroad Genomics. Results: Approximately approximately one thousand transcripts showed differential expression between the WT and TCF20 KO brain cortex, with a fold change ≥1.5 and p value <0.05. Gene ontology (GO) analysis showed that the down-regulated genes were enriched in the terms related to neurogenesis, neuronal specification, neural differentiation and secretion by cells. Up-regulated genes showed a significant enrichment of terms involved in up regulation of hypersensitivity and up regulation of inflammatory response. These results reflected the importance of TCF20 in cortical neurogenesis. Conclusions: We conclude that RNA-seq based transcriptome characterization would provide a framework for understanding how TCF20 gene contribute to brain cortical development.

Proteomic Analysis of Proteins Downstream of Autism-Associated Gene DIXDC1

Project description:Dix domain containing 1 (Dixdc1) is an important regulator of neuronal development including cortical neurogenesis, neuronal migration and synaptic connectivity, and sequence variants in the gene have been linked to autism spectrum disorders (ASD). Previous studies indicate that Dixdc1 controls neurogenesis through Wnt signaling, while its regulation of dendrite and synapse development requires Wnt and cytoskeletal signaling. However, the prediction of these signaling pathways is primarily based on the structure of Dixdc1. Given the role of Dixdc1 in neural development and brain disorders, we hypothesized that Dixdc1 may regulate additional signaling pathways in the brain. We performed proteomic analyses of Dixdc1 KO mouse cortices to reveal such alterations.
