Project description:This SuperSeries is composed of the following subset Series: GSE40537: IP of 5-hydroxymethylcytosine (5-hmC) enriched DNA fragments from control and PB treated mouse livers GSE40538: IP of 5-methylcytosine (5-mC) enriched DNA fragments from control and PB treated mouse livers GSE40773: Dynamic changes in liver 5M-bM-^@M-^P hydroxymethylcytosine profiles upon nonM-bM-^@M-^P genotoxic carcinogen exposure Refer to individual Series
Project description:5-hmC is a novel epigenetic mark derived from oxidation of methylcytosine. Phenobarbital (PB) is a well studied non-genotoxic carcinogen with roles in epigenetic perturbation. We profile 5hmC in both control mouse livers as well as in the livers of 28 day PB treated mice. 5hmC is largely found to reside in the bodies of active genes and promoter levels are perturbed upon PB induced gene activation events. 5-hmC is enriched in the bodies of active genes as well as a subset of TSS regions associated with transcriptional silencing. Upon PB exposire a handfull of genes are induced which reveal increases in promoter 5hmC levels
