Extraction protocol |
For ChIP-seq, sheared chromatin were subjected to immunoprecipitation with 2 μg antibody against H3K27ac (ab4729, Abcam), H3K4me1 (ab8895, Abcam) or 5 μg antibody against TEAD1 (610923, BD Biosciences). For RNA-seq, total RNA was extracted following manufacturer’s protocols (Qiagen) For Nano histone ChIP-seq, ChIP and input DNA were subjected to whole-genome amplification using the WGA4 kit (Sigma-Aldrich) and a universal primer linked to BpmI restriction site (Qiagen). 30ng of BpmI-digested DNA was used for ChIP-seq library preparation according to manufacturer’s protocols (New England Biolabs). For TF ChIP-seq, 30ng of ChIP and input DNA was used for library preparation. For RNA-seq, libraries were prepared accordingly using Tru-Seq Stranded Total RNA with Ribo-Zero Gold kit (Illumina), with an input of 1 μg total RNA.

Data processing |
For Nano ChIP-seq, sequenced reads were first trimmed to remove the first and last ten bases. No trimming was required for TF ChIP-seq. Sequenced reads were mapped to the human genome assembly (hg19) using Burrows-Wheeler Aligner (BWA-MEM, version 0.7.10). Only reads with MAPQ value of at least 10 were retained, and PCR duplicates were removed using SAMtools (version 0.1.19). Significant ChIP enrichment peaks relative to input were identified using MACS2 callpeak function. Wiggle track visualizations were generated using MEDIPS (version 1.20.1). For RNA-seq, sequenced reads were aligned to hg19 using STAR mapper and gene expression abundance was estimated with RSEM as fragments per kilobase per million (FPKM) using default parameters (pipeline available at https://github.com/gis-rpd/pipelines/tree/master/rnaseq/star-rsem).
