Glucocorticoid receptor profiling in IMR90,K562 and U2OS (ChIP-seq)

ABSTRACT: To identify the sequences responsible for recruitment of Glucocorticoid receptor (GR) to individual loci, we performed ChIP-seq and ChIP-exo that combines chromatin immunoprecipitation with an exonuclease digestion step. We performed these experiments in three cell lines : IMR90 (ATTC:CCL-186), U2OS osteosarcoma cell lines, K562 (ATCC:CCL243), upon glucocorticoid treatment. The U2OS assays are the same as those in E-MTAB-2731.

The classical DNA recognition sequence of the glucocorticoid receptor (GR) appears to be present at only a fraction of bound genomic regions. To identify sequences responsible for recruitment of this transcription factor (TF) to individual loci, we turned to the high-resolution ChIP-exo approach. We exploited this signal by determining footprint profiles of TF binding at single-base-pair resolution using ExoProfiler, a computational pipeline based on DNA binding motifs. When applied to our GR an  ...[more]
