Ethanol Regulation Of Glucocorticoid Responsive Genes, Blair Costin
Theses and Dissertations
Glucocorticoid hormones modulate acute and chronic behavioral and molecular responses to drugs of abuse including psychostimulants and opioids. Acute ethanol activates the hypothalamic pituitary adrenal (HPA) axis causing the release of adrenal glucocorticoid hormones, but following chronic ethanol the HPA axis is dysregulated in both humans and rodents. Thus, there is growing evidence that glucocorticoids might also modulate behavioral and molecular responses to ethanol. Previous microarray studies in the Miles’ laboratory have shown that the well-known glucocorticoid responsive gene, Serum and Glucocorticoid-regulated Kinase 1, Sgk1, is prominently up regulated by acute ethanol (2 g/kg) in the prefrontal cortex (PFC) of …
