Alcoholism is a complex disorder influenced by interactions between genetic and environmental risk factors. This study examined the influence of isolate housing on ethanol intake in alcohol-preferring (P) and non-alcohol-preferring (NP) rats. Rats were isolate-housed or pair-housed for 8 weeks when between 45 and 96 days old. Ethanol drinking was assessed using a 24-hr preference test (10% ethanol vs. water) and 20-min limited access tests. A behavioral test battery was used to assess anxiety-like, depressive-like, acoustic startle, and motor behavior. Isolate housing increased home cage drinking in both lines and increased limited access drinking selectively in P rats. Isolation also reduced swim test immobility and prepulse inhibition in P rats and increased locomotor stereotypies in NP rats. Taken together, these data demonstrate that LinexEnvironment interactions influence the effects of isolation. Furthermore, isolation selectively increased ethanol intake in high drinking P rats. This effect was not correlated with changes in other behaviors. Selective enhancement of limited access ethanol drinking in P rats may represent a model whereby genetic liability to excessive drinking is enhanced by specific environmental exposures.
