Abstract

Mice selectively bred for high (FAST) or low (SLOW) locomotor stimulant response to ethanol have been found to differ in response to drugs with gamma-aminobutyric acid (GABA)-ergic actions. Reverse selection produced lines that are similar in sensitivity to ethanol stimulation (r-FAST and r-SLOW) and provided a unique model for testing hypotheses about shared genetic influence on sensitivity to ethanol and GABAergic drugs. FAST mice were more stimulated than SLOW mice by all drugs tested: ethanol, methanol, n-propanol, t-butanol, pentobarbital, diazepam, and allopregnanolone. In contrast, r-FAST and r-SLOW mice differed in sensitivity to only a few isolated drug doses. Locomotor responses of each reverse-selected line were significantly different from the responses of their respective forward-selected line for all drugs. Results support an effect of selection for ethanol sensitivity on allosteric modulation of the GABA-A receptor.
