delta-Aminolaevulinate synthase in human HepG2 hepatoma cells. Repression by haemin and induction by chemicals.

delta-Aminolaevulinate (ALA) synthase, the rate-limiting enzyme in haem biosynthesis in the normal liver, was examined in human HepG2 hepatoma cells. Haemin, up to 100 microM, had no effect on ALA synthase activity in vitro; it did, however, exhibit a dose-dependent inhibitory action when added to c...
