Abstract

Cocaine-and-Amphetamine Regulated Transcript peptide (CART peptide) is known for having an inhibitory effect on dopamine (DA)- and cocaine-mediated actions and is postulated to be a homeostatic, regulatory factor in the nucleus accumbens (NAc). Some sex differences in cocaine-mediated locomotor activity (LMA) and in the expression and function of CART peptide have been reported. However, it is not known if the inhibitory effect of CART peptide on cocaine-mediated LMA is sexually dimorphic. In this study, the effects of CART 55-102 on LMA due to intra-NAc DA and i.p. cocaine were determined in male and female Sprague-Dawley rats. The results show that CART 55-102 blunted or reduced both the DA- and cocaine-induced LMA in both males and females. In conclusion, CART peptide is effective in blunting DA- and cocaine-mediated LMA in both males and females.
