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-mC is an epigenetic modification of the DNA base cytosine with roles in gene silencing events, imprinting and X inactivation. Phenobarbital (PB) is a well studied non-genotoxic carcinogen with roles in epigenetic perturbation. We profile 5mC in both control mouse livers as well as in the livers of 28 day PB treated mice. 5mC is largely found to reside in the bodies of active genes and promoter levels are perturbed upon PB induced gene activation events. 5-mC is assocated with promoters fo silent genes. Upon PB exposire a handfull of genes are induced which reveal decreases in promoter 5mC levels
