PRDM16 orchestrates neuron-vascular communication for angiogenesis during brain development

ABSTRACT: Purpose:To gain a deeper insight into how PRDM16 regulates neuron-vascular communication for angiogenesis, RNA-sequencing (RNA-seq) was performed to analyze the genome-wide changes by PRDM16 deletion at E15. Methods: Total RNA was extracted from E15 telencephalic tissue of Prdm16cKO and Prdm16fl/fl 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 Prdm16fl/fl and Prdm16cKO 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, blood vessel development and secretion by cells. Up-regulated genes showed a significant enrichment of terms involved in negative regulation of cell communication and negative regulation of angiogenesis. These results reflected the importance of PRDM16 in cortical development. Conclusions: We conclude that RNA-seq based transcriptome characterization would provide a framework for understanding how Prdm16 gene contribute to brain cortical development.
