Simultaneous Mapping of Enhancers and Enhancer Rearrangements with Paired-End H3K27ac ChIP-seq.

We describe a protocol for H3K27ac ChIP paired-end sequencing and computational analysis of rearrangements. Our approach can be used to simultaneously map enhancers and their activity and to identify structural variations at enhancers. Since changes in enhancer activity and new enhancer translocations both play a major role in tumor initiation, progression, and response to therapy, this approach holds promise to uncover some of the mechanisms behind these processes.
