The relative importance of ADH and MEOS for ethanol oxidation in the liver has yet to be elucidated. The discovery of a strain of deermice genetically lacking ADH (ADH-) which can consume ethanol at greater than 50% of the rates seen in deermice having ADH (ADH+) suggested a significant role for non-ADH pathways in vivo. To quantitate contributions of the various pathways, we examined first the ethanol oxidation rates with or without 4-methylpyrazole in isolated deermice hepatocytes. 4-Methylpyrazole significantly reduced the ethanol oxidation in both ADH+ and ADH- hepatocytes. The reduction seen in ADH- cells can be applied to correct for the effect of 4-methylpyrazole on non-ADH pathways of ADH+ deermouse hepatocytes. After correction, non-ADH pathways were found to contribute 28% of ethanol metabolism at 10 mM and 52% at 50 mM. When using a different approach namely measurement of the isotope effect, MEOS was calculated to account for 35% at low and about 70% at high blood ethanol concentrations. Thus, we found that two different complementary approaches yielded similar results, namely that non-ADH pathways play a significant role in ethanol oxidation even in the presence of ADH.
