library_construction_protocol: Genomic DNA was isolated using Dneasy (Qiagen) protocol. DNA was further used for the constructions of sequencing libraries ATAC-Seq libraries were prepared from T cells cocultured with Res-ctrl or Res-shFabp7 for 48 hours at the MD Anderson Epigenomics Profiling Core Facility. The ATAC-Seq libraries were sequenced by using a 2´76 base paired-end protocol on an Illumina NovaSeq 6000 instrument at the MD Anderson Advanced Technology Genomics Core. In total, six ATAC-Seq libraries (three biological replicates per condition) were sequenced, generating 35-75 million pairs of reads per sample. Each pair of reads represents a DNA fragment from the library
