Identification of PPARγ super-enhancers
For identification of PPARγ super-enhancers individual PPARγ peaks were stitched
together if they were within 12,500 bp, as previously described (Whyte et al. 2013).
Sequence tag information for MED1 and input control were obtained in a window
corresponding to the stitched PPARγ peak region. All identified PPARγ regions were
then ranked according to increasing total MED1 ChIP-seq signal (with subtraction of
input) in the given regions. Regions with more than 200 input-subtracted MED1
ChIP-seq tags per 10 M total reads in two independent MED1 ChIP-seq replicates
were regarded as PPARγ super-enhancers. In total, 1,212 PPARγ super-enhancers
