Abstract:
|
Epigenome is a crucial component for understating gene regulation. The massive amounts of data generated by the Roadmap Epigenomics project create an opportunity to study the coordination of different types of epigenomic signals from different cis-regulatory elements. Here we develop Epigenome Isoform Analysis (EIA) to systematically discover and analyze such coordination patterns using a hierarchical latent mixture model. We show that cis-regulatory element isoforms discovered by EIA provides a concise but biologically meaningful description of the highly complex epigenome landscape. We demonstrate its use in analyzing epigenomic changes between different biological conditions.
