Co-methylation

Abstract:
CpG methylation is a mitotically heritable epigenetic mark on DNA which plays a key role in genomic imprinting, X-inactivation, transcriptional regulation, tissue specificity and carcinogenesis. What is co-methylation? Loosely, it is the persistence of the methylated (M) or unmethylated (U) state along a chromosome. Slightly more precisely, it is the association between the methylation state at nearby CpGs, as a function of their separation. "Co-" here is meant to bring to mind correlation. This talk will summarize some results concerning co-methylation we obtained by analyzing publicly available sequence data on whole genome bisuplhite-treated DNA. Our immediate goal was to see whether we can simulate whole-genome methylation data that is indistinguishable from the real thing. I'll explain why we want to do this. It turns out to be quite hard (for us).
