Abstract：
BACKGROUND:Alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH), which are most abundant in the liver, are the main enzymes involved in ethanol and acetaldehyde metabolism. AIMS:The purpose of this study was to compare the activity of ADH isoenzymes and ALDH between liver carcinoma cells and healthy hepatocytes. PATIENTS:Samples were taken from 44 liver cancer patients (19 drinkers, 25 nondrinkers). Seventeen patients had primary liver tumors and 27 had metastatic liver tumors. METHODS:Fluorimetric methods were used for measurement of the activity of class I and II ADH isoenzymes and ALDH activity. Total ADH activity and activity of class III and IV isoenzymes were measured by a photometric method. RESULTS:The activities of total ADH, ALDH, and class I ADH were significantly higher in cancer cells than in healthy tissues. The other tested classes of ADH showed a tendency toward higher activity in cancer than in normal cells. The differences between enzymes of drinkers and nondrinkers in both cancer and healthy tissue, were not significant. CONCLUSION:Differences in the activities of total ADH, ALDH and class I ADH isoenzyme between cancer liver tissues and healthy hepatocytes might be a factor in ethanol metabolism disorders, which can intensify carcinogenesis.
