Gene Affected
Origin High alcohol-preference (HAP) rats and Low alcohol-preference (LAP) rats were developed in the laboratory, Department of Legal Medicine, Hyogo College of Medicine, by selective inbreeding from the Wistar colony of rats. The ethanol preference of the rats was assessed by the one-lever two-liquid chamber method. (Iso and Sakaki, 1982).
Strain characteristics HAP and LAP rats show different ALDH1 phenotypes, different blood acetaldehyde concentration following ethanol administration, and different expression level of corticosterone and proopioomeranocortin. Furthermore HAP have a significantly higher sensitivity than LAP for methamphetamine.
