Table 2. Genotype difference in blood ethanol concentration (BEC) in male nPE1 mice.

After mice were subjected to the 4-day DID paradigm followed by a 3-week IA drinking paradigm, in session 11 after 4-hour alcohol drinking, blood from each mouse was collected for BEC levels. Genotype difference: *p<0.05 or **p<0.01 vs. nPE1^+/+ mice by Student’s t-tests (n=6 for each group). Data presented as mean ± SEM.

Genotype	nPE1+/+ (n=6)	nPE1−/− (n=6)
Alcohol intake, g/kg	5.4 ± 0.49	2.9 ± 0.22*
BEC, mg/ml	0.49 ± 0.03	0.24 ± 0.03**
