Abstract
Heme oxygenase, the rate controlling enzyme for heme catabolism, is inducible by a variety of treatments, some of which induce by a heme-dependent mechanism and others by a heme-independent mechanism. This work shows that, in cultured chick embryo liver cells, synergistic induction of heme oxygenase by iron, added with the phenobarbital-like drug, glutethimide was heme-dependent. Addition of an inhibitor of heme biosynthesis abolished the synergistic induction of heme oxygenase providing evidence for the heme-dependent mechanism of induction. Glutethimide and iron appeared to induce at the transcriptional level since both heme oxygenase mRNA and protein levels correlate with changes in heme oxygenase activity.
