Abstract

A limiting factor determining the sensitivity of a cell to glucocorticoid hormones is the intracellular concentration of the glucocorticoid receptor (GR) protein. By regulating the expression of GR the cell is able to adapt to both changes in its hormone environment and to the varying requirements for biological response. Studies on the regulation of GR expression have shown this to be a complex process which involves both transcriptional and posttranscriptional mechanisms. Although GR is more or less constitutively expressed in most tissues its concentration varies under different physiological conditions. GR expression is regulated by a number of different agents including factors which act through a second messenger pathway. This allows the cell to control glucocorticoid regulated gene expression through a complex but integrated hormonal network. Here we summarize our studies on GR regulation with emphasis on: i), GR autoregulation; ii), the effect of cAMP on GR expression; and iii), GR expression during fetal rat lung development.
