Abstract

There is considerable evidence that the level of cerebral serotonin plays a key role in the volitional consumption of ethanol in both man and animals. Naive alcohol-preferring C57BL/6J mice have been shown to have a lower cerebral serotonin content compared to the non-preferring CBA/Ca mouse strain. This has been attributed to the enhancement of hepatic tryptophan pyrrolase activity in C57 mice. Activity and/or expression of tryptophan pyrrolase may be an important biological determinant of alcohol preference. We have investigated the possible mechanism/s underlying this strain difference in tryptophan pyrrolase activity by assaying both mRNA levels encoding for the tryptophan pyrrolase gene and by mutational analysis of tryptophan pyrrolase cDNA. We were unable to demonstrate any difference in tryptophan pyrrolase mRNA levels between naive C57 and CBA mice. Tryptophan pyrrolase mRNA levels were increased following starvation in C57 mice and following glucocorticoid administration in both C57 and CBA mice. Heteroduplex mutational analysis failed to detect any tryptophan pyrrolase cDNA sequence heterogeneity between these mice strains.
