Inverse correlation between hepatic proteasome activity and serum ethanol levels in ethanol-fed rats. Data are derived from four separate studies in which rats were fed liquid control or ethanol diets for four to six weeks. Each data point is the proteasome chymotrypsin-like activity in one ethanol-fed rat, expressed as percent of the same activity of its pair-fed control rat. Data points are plotted as a function of the serum ethanol concentration in each animal. The plot was drawn by linear regression and statistically analyzed.
