Researchers at the University of Colorado in Denver found that genes identified as contributors to patterns of alcohol use are not the same as those linked to the predisposition to alcoholism. Thus, although some people are programmed to enjoy a drink more than others, they are not any more likely to become dependent. The team experimented first on rats and then on humans before determining that drinking behavior is linked to pleasure/reward and appetite/satiety pathways in the brain, distinguishing this newly discovered gene from the previously isolated alcoholism gene.
