RNASeq in mouse Alkbh1 KO and WT ESC

ABSTRACT: It has widely accepted that 5-methylcytosine is the only form of DNA methylation in mammalian genomes, whereas the other forms, such as N6-methyladenine, primarily exist in prokaryotes and only a few eukaryotes. Herein, we demonstrated the surprising presence of N6-methyladenine in mammalian genomes, especially, mouse embryonic stem cells. This modification is enriched at histone variant H2A.X-deposited genomic regions in wild type embryonic stem cells. Our work also showed that a previously unknown DNA demethylase, Alkbh1, is the major demethylase for N6-methyladenine in embryonic stem cells. Increase of N6-methyladenine levels in Alkbh1 deficient cells leads to silencing of genes that regulate embryonic development. Surprisingly, genes located on the X-chromosome, but not the Y-chromo
