MacroH2A deletion causes neuronal developmental deficits and autism-like behavior in mice

Purpose:To further understand how MacroH2A regulates the proliferation of neural progenitor cells, RNA-seq was used to analyze genome-wide changes in the cerebral cortex and littermate wild type of E13.5 MacroH2A knockout mice Methods: Total RNA was extracted from wild-type E13.5 brain tissue and knock-out E13.5 brain tissue. Specifically, the Agilent 2100 Bioanalyzer was used for quality control and quantification. Total RNA was then converted to cDNA and combined with the library. Illumina HiSeq 2500 platform in Annoroad Genomics uses RNA sequencing analysis Results: Approximately one thousand transcripts showed differential expression between the wild-type(WT) and knock-out 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 MacroH2A plays a role in brain neuron development. Total mRNA profiles of E13.5 wild type (WT) and knock-out(KO) mice were generated by deep sequencing using Illumina HiSeq 2500.
