In Arabidopsis, transcriptional gene silencing (TGS) can be triggered by 24 nt small-interfering RNAs (siRNAs) through the RNA-directed DNA methylation (RdDM) pathway. By functional analysis of NERD, a GW repeat- and PHD finger-containing protein, we demonstrate that Arabidopsis harbors a second siRNA-dependent DNA methylation pathway targeting a subset of nonconserved genomic loci. The activity of the NERD-dependent pathway differs from RdDM by the fact that it relies both on silencing-related ...[more]

IP of 5-methylcytosine (5-mC) enriched DNA fragments from control and PB treated mouse livers (1 day)

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 1 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 comparison of 5-mC profiles in 5 control and 5 PB exposed mouse livers (dose: 1day PB)
