Μηχανισμοί δράσης των γλυκοκορτικοειδών: Διερεύνηση του ρόλου του υποδοχέα hGRβ in vivo σε διαγονιδιακά μοντέλα ποντικών

Mechanisms of glucocorticoid actions: Investigating the in vivo role of hGRβ receptor in transgenic mice models
Summary:
Glucocorticoids (GCs) are hormones, essential for the stress response in humans and are commonly used in treating autoimmune, inflammatory and lymphoproliferative diseases. Their receptor (Glucocorticoid Receptor, GR) is an evolutionarily conserved protein, of the superfamily of nuclear receptors, regulating the diverse actions of glucocorticoids, acting as a transcription factor. This protein moves from the cytosol to the nucleus after binding to its ligand, GCs, and modifies the transcription rates of genes responding to glucocorticoids, in a positive or negative manner. There are many different isoforms of GR, one of which, GRβ, is very interesting, since it has a dominant negative effect on the functional GR isoform, GRα. The GRβ isoform is also correlated to pathologies or therapeutic consequences. In this study, we created transgenic mice that overexpress human GRβ, in order to determine the transcriptional levels of genes regulated by glucocorticoids and observe the endocrinological changes.
