Endothelial Arid1a Deletion Disrupts the Balance among Angiogenesis, Neurogenesis, and Astrogenesis in the Developing Brain

Purpose:To gain futher insight into how endothelial Arid1a regulates the angiogenesis, neurogenesis, and astrogenesis,RNA-seq was used to analyze the genome-wide changes resulting from isolated endothelial cells of E15 Arid1a endothelial conditional knockout mice and littermate wild-type. Methods: mRNA from E15 isolated endothelial cells of Arid1afl/fl and Arid1acKO-Tie2 mice was extracted. Specifically, Agilent 2100 Bioanalyze was used to quality controlled and quantified. then, mRNA was converted to cDNA and bound the library. RNA-sequencing analysis was used by the Illumina HiSeq 2500 platform in Annoroad Genomics. Results: Approximately one six thousand transcripts showed differential expression between the Arid1afl/fl and Arid1acKO-Tie2 mice brain cortex, with a fold change >=2 and p value <0.05.Geneontology analysis of the up-regulated genes showed obvious enrichment of biological processes related to development process and regulation of cell communication.The down-regulated genes exhibited enrichment of biological processes related to cell movement. These results reflected endothelial Arid1a plays a vital role in cortex development. Conclusions: Endothelial Arid1a RNA-seq would provide a overall understanding how endothelial Arid1a regulates the Balance among angiogenesis, neurogenesis, and astrogenesis in the developing Brain mRNA profiles of E15 Arid1afl/fl and Arid1acKO-Tie2 mice were generated by deep sequencing, in triplicate, using Illumina HiSeq 2500.
