Project description:DNA methylation dynamics influence brain function and are altered in neurological disorders. 5-hydroxymethylcytosine (5-hmC), a DNA base derived from 5-methylcytosine (5mC) accounts for ~40% of modified cytosine in brain, and has been implicated in DNA methylation-related plasticity. Here we map 5-hmC genome-wide across three ages in mouse hippocampus and cerebellum, allowing assessment of its stability and dynamic regulation during postnatal neurodevelopment through adulthood. We find developmentally programmed acquisition of 5-hmC in neuronal cells. Epigenomic localization of 5-hmC-regulated regions reveals stable and dynamically modified loci during neurodevelopment and aging. By profiling 5-hmC in human cerebellum we establish conserved genomic features of 5-hmC. Finally, we implicate 5-hmC in neurodevelopmental disease by finding that its levels are inversely correlated with methyl-CpG-binding protein 2 (Mecp2) dosage, a protein encoded by a gene in which mutations cause Rett Syndrome. These data point toward critical roles for 5-hmC-mediated epigenetic modification in neurodevelopment and diseases. Here we map 5-hmC genome-wide across three ages in mouse hippocampus and cerebellum, allowing assessment of its stability and dynamic regulation during postnatal neurodevelopment through adulthood. Profiling of 5-hmC in human cerebellum we establish conserved genomic features of 5-hmC. Finally, we implicate 5-hmC in neurodevelopmental disease by profiling 5-hmC in mouse cerebellum lacking MeCP2, a protein encoded by a gene in which mutations cause Rett Syndrome.

Project description:Epigenetic modifications, such as cytosine methylation and histone modification, have been shown involved in the pathology of ischemic brain injury. Recent works have implicated 5-hydroxymethylcytosine (5hmC), a DNA base derived from 5-methylcytosine (5mC) through the oxidation by Ten-Eleven Translocation (TET) enzymes, in DNA methylation-related plasticity. In this study we show that 5hmC abundance could be induced to increase by ischemia injury. Genome-wide profiling of 5hmC identified differentially hydroxymethylated regions (DhMRs) associated with ischemic injury and DhMRs were found enriched among the genes involved in cell junction, neuronal morphogenesis and neurodevelopment. These data together suggest that 5hmC modification could serve as a potential therapeutic target for the treatment of ischemic stroke. To determine the genome-wide 5hmC distribution in both ischemic injury (I/R) and control mice (C57BL/6), we employed a previously established chemical labeling and affinity purification method, coupled with high-throughput sequencing (Song et al, Nature Biotechnology, 2011). The ischemic or matched control brain tissues from three pairs of ischemic mice and control mice were used for the analyses.
