Surprisingly few pathways signal between cells, raising questions about mechanisms for tissue-specific responses. In particular, Wnt ligands signal in many mammalian tissues, including the intestinal epithelium, where constitutive signaling causes cancer. Genome-wide analysis of DNA cis-regulatory r...

Cell differentiation requires epigenetic modulation of tissue-specific genes and activities of master transcriptional regulators, which are recognized for their dominant control over cellular programs. Using novel epigenomic methods, we characterized enhancer elements specifically modified in differ...

The compaction degree of chromatin is intimately related to its functionality and active cis-regulatory elements typically exist within open chromatin regions depleted in nucleosomes (Heintzman et al. 2007; Boyle et al. 2008). These domains can be identified using Formaldehyde-Assisted Isolation of ...
