Genes that drive you to drink but don't make you an alcoholic
November 13th, 2009
Your genetic make up may predispose you to drink more but may not increase your genetic risk for alcoholism (alcohol dependence). Research published in the open access journal, BMC Biology, pinpoints genetic pathways and genes associated with levels of alcohol consumption but not with alcohol dependence in rats and humans. Led by Boris Tabakoff, Laura Saba and Paula Hoffman from the University of Colorado, Denver, USA, the research team used rats to identify the genetic pathways affecting alcohol drinking behaviour. They found that the rats' drinking behavior was linked to the pleasure and reward pathways in the brain and also linked to some of the same genetic systems...
