Genome-wide maps of ALKBH1 binding sites in mouse primary hepatocytes


ABSTRACT: AlkB homolog 1 (ALKBH1) has been reported to act as a DNA 6mA demethylase to remove 6mA modification in eukaryotic genomes. Our previous data showed downregulated ALKBH1 in mouse and human fatty liver and increased DNA 6mA levels in mouse fatty liver. We developed liver-specific ALKBH1 knockout (AKO) mice to directly study the role of ALKBH1 mediated DNA 6mA modification during the development of hepatic steatosis. Deletion of liver ALKBH1 promoted hepatic steatosis and insulin resistance. Overexpression of ALKBH1 resulted in opposite phenotypes. To investigate the mechanism of ALKBH1 in regulating target gene expression. We performed ChIP-seq for identifying ALKBH1 binding sites on mouse hepatocytes genomes and validated its demethylase activity for DNA 6mA modification on the target genes via ChIP-qPCR assays.
