Abstract

We studied the effects of acute, subacute, and chronic alcohol treatment of rats on the content of fibroblast growth factor 2 (FGF2) mRNA in various brain structures. Results suggest a possible role of FGF2 in the functioning of dopaminergic neurons in the midbrain. In our experiment, ethanol treatment of rats was accompanied by an increase in the FGF2 mRNA level in the emotiogenic structures of the brain. This effect was blocked by pretreatment of animals with chlorpromazine. This suggests FGF2 involvement in the mechanisms of alcohol dependence and can be considered as a possible diagnostic and therapeutic target in alcoholism.
