Abstract

Glucocorticoids and their receptor (GR) have been an important area of research because of their pleiotropic physiological functions and extensive use in the clinic. In addition, the association between GR and glucocorticoids, which is highly specific, leads to rapid nuclear translocation where GR associates with chromatin to regulate gene transcription. This simplified model system has been instrumental for studying the complexity of transcription regulation processes occurring at chromatin. In this review we discuss our current understanding of GR action that has been enhanced by recent developments in genome wide measurements of chromatin accessibility, histone marks, chromatin remodeling and 3D chromatin structure in various cell types responding to glucocorticoids.
