Glucocorticoids act through the glucocorticoid receptor (GR) to regulate cell function. GR gamma (GRγ) is a constitutive exon3/4 splice variant, contributing 4–8% of the total GR transcripts and is highly conserved through mammalian evolution, but its biological function remains unknown. Using microarray analysis we identified the transcriptome response for GRγ in stable HEK-Flp cells. This revealed that although GRγ effectively modulated gene expression in...

Glucocorticoids (Gcs) act via the intracellular glucocorticoid receptor (GR) to regulate cellular homeostasis. GR is a ligand-activated transcription factor which mediates effects within the nucleus or cytoplasm to regulate genomic or non-genomic events. Localisation of the GR to a specific cellular compartment is therefore an important determinant of the cellular response to Gcs.Live cell imaging of GR trafficking in cells transfected with fluorophore-t...
