GO analysis yielded 4 significant MF categories, containing at least 5 proteins (Table 4). There were no significant BP categories containing at least 5 proteins. In all 4 MF categories, there were more proteins with higher expression levels in the ACB-shell of the ethanol than saline group, i.e., GTP binding (all 7 proteins were higher in the ethanol group), ATP-binding (all 6 proteins were higher in the ethanol group), DNA-binding (6 of 8 proteins were higher in the ethanol group), and protein binding (13 of 17 proteins were higher in the ethanol group).
