Microglial metabolism mediated by BACH1 orchestrates astrogenesis during brain development


ABSTRACT: Purpose: To gain futher insight into how microglia-derived BACH1 regulates microglial metabolism and astrogenesis, RNA-seq was used to analyze the genome-wide changes resulting from isolated microglia of E16 microglial BACH1 conditional knock out mice and littermate wild-type. Methods: mRNA from E16 isolated microglia of Bach1fl/fl and Bach1cKO-Cx3 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 Bach1fl/fl and Bach1cKO-Cx3 mice brain microglia, with a fold change ≥3 and p value <0.05. Geneontology analysis of the downregulated genes were enriched in terms related to cell proliferation, glial cell differentiation and cell communication and upregulated genes were enriched in terms related to negative regulation of cell proliferation, negative regulation of astrocyte differentiation and glial cell fate commitment. These results reflected microglia BACH1 plays roles in cortex development. Conclusions: Microglia BACH1 RNA-seq would provide a overall understanding how microglia-derived BACH1regulates astrogenesis during brain development.
