it appears possible that alteration of concentration of endogenous adenine nucleotides may control the process of diethoxycarbonyldihydrocollidine-mediated induction of delta-aminolaevulinate synthetase , since treatment with atp , cyclic amp or theophylline produced inhibition similar to that under hypobaria and hypoxia .
