Tracking the evolution of cancer methylomes
Abstract
Cellular transformation in cancer has long been associated with aberrant DNA methylation, most notably, hypermethylation of promoter sequences. A new study uses a clever approach of selective high-resolution profiling to follow DNA methylation over a time course of cellular transformation and challenges the notion that hypermethylation in cancer arises in an orchestrated fashion.
