The human gene FOXM1 promotes cortical folding and improves learning and memory ability in mice [E15]

Purpose: To gain futher insight into how FOXM1 regulates the proliferative of neural progenitors ,RNA-seq was used to analyze the genome-wide changes resulting from the cerebral cortices of E15 FOXM1 conditional knock in mice and littermate wild-type. Methods: Total RNA from E15 telencephalic tissue of wild-type(WT) and FOXM1f/+;Nestin-Cre mice was extracted. Specifically, Agilent 2100 Bioanalyze was used to quality controlled and quantified. then, total RNA 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 FOXM1f/+;Nestin-Cre mice brain cortex, with a fold change =1.5 and p value <0.05.Geneontology analysis of the up-regulated genes showed obvious enrichment of biological processes related to development and proliferation.The down-regulated genes exhibited enrichment of biological processes related to the negative regulation of cell proliferation and developmental process. These results reflected human FOXM1 plays a role in cortex development. Conclusions: RNA-seq based transcriptome characterization would provide a overall understanding how FOXM1 gene contribute to brain cortical development. Overall design: Total mRNA profiles of E15 wild type (WT) and FOXM1f/+;Nestin-Cre mice were generated by deep sequencing, in triplicate, using Illumina HiSeq 2500.
