Endothelial UCP2 regulates the neurogenic-to-astrogenic fate switch during brain development

Purpose: To gain futher insight into how endothelial UCP2 regulates the neurogenic-to-astrogenic fate switch ,RNA-seq was used to analyze the genome-wide changes resulting from isolated endothelial cells of E14.5 and E17.5 UCP2 endothelial conditional knock out mice and littermate wild-type. Methods: mRNA from E15 and E18 isolated endothelial cells of wild-type(WT) and UCP2f/f;Tie2-cre 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 thousand transcripts showed differential expression between the wild-type(WT) and UCP2ECKO 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 fate commitment. These results reflected endothelial UCP2 plays roles in cortex development. Conclusions: Endothelial UCP2 RNA-seq would provide a overall understanding how endothelial UCP2 regulates the neurogenic-to-astrogenic fate switch during brain development mRNA profiles of E15 and E18 wild type (WT) and UCP2ECKO mice were generated by deep sequencing, in triplicate, using Illumina HiSeq 2500.
