Among the 28 proteins that were altered by ethanol in the ACB-shell of W rats (Table 5), there were 11 that were similarly changed in P or NP rats. Only one protein changed in the opposite direction with ethanol treatment in the W rats versus either P or NP rats, i.e., 19 kDa protein had lower expression levels in the ethanol-treated W rats and higher levels in the ethanol-treated NP line. Therefore, expression levels of 17 proteins were uniquely changed by ethanol in the ACB-shell of W rats (Table 5).
