IECs were isolated from the duodenum (anterior 5 cm of midgut), ileum (posterior 6 cm of midgut), and colon (6 cm of terminal hindgut) of 8 to 12-week old mice ; Nuclei were isolated by 0.1% NP-40 lysis for DNase digestions ; Total RNA extracted by cell lysis in TRIzol reagent (Invitrogen) and further purified using Qiagen RNeasy kit according to manufacturer's protocol DNase-seq libraries were prepared as described (Song and Crawford 2010; PMID:20150147) with 5 µg of DNA pooled from nuclei digested for 2 min, 4 min, and 8 min at 37°C with no exogenous DNase I added ; RNA-seq libraries were prepared with 2 micrograms total RNA used for standard TruSeq library preparation (Illumina) with polyA selection and sequenced with 2 x 50bp paired-end reads
