Abstract

Ethanol has been considered as a lifestyle risk factor for cancer in humans. While some studies have indicated that alcohol intake has a preventive effect for renal cell cancer, others have not. The metabolism of alcohol in cancer cells may be in many ways different than in healthy tissue and its disturbances could be associated with carcinogenesis. The aim of this study was to compare the metabolism of renal cell cancer cells and normal renal cells by measurement of ADH isoenzymes and ALDH activities in these tissues. The study material consisted of 43 cancerous renal tissues (14 patients in stage II, 19 in stage III and 10 in stage IV). Class III and IV ADH and total ADH activities were measured by the photometric method and class I and II ADH and ALDH activities by the fluorometric method with class-specific fluorogenic substrates. The activity of the class I ADH isoenzyme and the total ADH was significantly higher in every stage of renal cell cancer as compared to healthy tissues. Analysis of ALDH activity did not show statistically significant differences between cancer and healthy cells. The increased activity of total ADH in renal cell cancer, especially the class I isoenzyme and normal activity of ALDH, may be the facto...Continue Reading

Cancer Metabolism

In order for cancer cells to maintain rapid, uncontrolled cell proliferation, they must acquire a source of energy. Cancer cells acquire metabolic energy from their surrounding environment and utilize the host cell nutrients to do so. Here is the latest research on cancer metabolism.
