After treatment with 100 nM Dex, 10 uM CpdA or vehicle for 1 h, MDA-MB-231 cells were crosslinked with 1% formaldehyde for 10 min. Sonicated chromatin was enriched by immunoprecipatation with an anti-GR antibody. MDA-MB-231 cells were treated with 100 nM Dex, or 10 M CpdA for 2h and 4h, respectively. RNA was extracted using the RNeasy Mini Kit. For ChIP-exo, T4 DNA polymerase, T4 PNK, and Klenow DNA Polymerase were used together for end polishing. The ligation step was performed with less reducing agent. Protein A Dynal magnetic beads were washed using modified RIPA buffer (50mM Tris-HCL pH 7.8, 1mM EDTA, 0.25% Na Deoxycholate, 1% NP-40, 0.5M LiCl). The library was amplified with only 10 or 12 PCR cycles, and prepared without gel-based size selection. For RNA-seq, libraries were constructed using the Illumina Truseq RNA Sample Prep Kit according to the manufacturer's protocol.
