Alcohol induction of ferritin expression in a human hepatoblastoma cell line (HEP G2)

Alcohol Clin Exp Res. 1990 Dec;14(6):847-52. doi: 10.1111/j.1530-0277.1990.tb01826.x.

Abstract

Hyperferritinemia, an unclear mechanism, is frequently observed in chronic alcoholics. The aim of this work was to study the effect of alcohol on ferritin expression in a human hepatoblastoma cell line, HepG2. This cell line proved to be sensitive to alcohol, since alcohol increased gamma-GT activity both in cells and media. The most striking result was the increase of ferritin in cells and media by alcohol. Moreover, this effect was specific, since it contrasted with a decrease in total protein synthesis and secretion, a decrease in transferrin excretion and a lack of effect on orosomucoid. In our model, alcohol was able to induce, in a specific manner, ferritin expression.
