09/15/1980 - "These studies suggest that induction of porphyria is a combination of two distinct processes: (a) induction of delta-aminolaevulinate synthase synthesis by destruction of cytochrome P-450 haem and consequent depletion of cellular free haem; (b) maintenance of continued delta-aminolaevulinate synthase synthesis by preventing replenishment of cellular haem either by inhibiting haem synthesis and/or by promoting continuous removal of newly synthesized haem."
