Immunoreactivity of cAMP response element binding protein is not altered in the post-mortem cerebral cortex or cerebellum of alcoholics

— We examined amounts of cAMP response element binding protein (CREB) and its phosphorylated form in post-mortem frontal and temporal cortices and cerebella from alcoholics and controls by immunoblotting. No significant differences were observed in the levels of these proteins in each brain region, suggesting that the assumed neuroadaptations to chronic ethanol intake may not be reflected by quantitative alterations of CREB in alcoholic brain.
