Abstract

Rat liver tryptophan (Trp) pyrrolase activity and gene expression were studied in relation to the alcohol-withdrawal syndrome (AWS). Both activity and gene expression were enhanced after withdrawal of ethanol-containing liquid diets and the time-course of these changes mirrored that of development and intensity of the behavioural disturbances of the AWS. By contrast, no correlation was observed between the AWS-induced behaviour and changes in activity of another hepatic glucocorticoid-inducible enzyme, tyrosine aminotransferase, and a negative correlation was noted between behaviour and the gene expression of this latter enzyme and also of that of the hepatic glucocorticoid receptor. We suggest that the metabolic consequences of activation of liver Trp pyrrolase during alcohol withdrawal may play a role in the behavioural features of the AWS.
