Influence of glucocorticoids and glucocorticoid receptor gene polymorphisms on glucose metabolism
In humans glucocorticoids (GS) regulate a broad spectrum of physiologic functions, including cell differentiation, metabolism and inflammatory responses. These hormones play an important role in the maintenance of basal and stress-related homeostasis. Furthermore, glucocorticoids represent one of the most widely used therapeutic compounds in the treatment of inflammatory, autoimmune and lymphoproliferative disorders. According to the classic genomic model GS bind to intracellular receptors (hGR) and directly or indirectly regulate gene transcription and synthesis of proteins responsible for inflammatory process. Alterations in hGR action may have important implications for many critical biological processes, such as the behavioral and physiologic responses to stress, the immune and inflammatory reaction, the process of sleep, as well as basic functions, such as growth and reproduction, or response to treatment. Glucocorticoids belong to the antagonistic hormons compared to insulin and play an important role in maintaining the homeostasis of glucose metabolism.
