title: Stimulation of aldosterone production by hemin in calf adrenal glomerulosa cell cultures.
abstract: Aldosterone production from 11-deoxycorticosterone was stimulated by hemin in primary cultures and homogenates of calf adrenal zona glomerulosa, in a time- and dose-dependent fashion. The ferrochelatase inhibitor 3,5-diethoxycarbonyl-1,4-dihydro-2,4,6-trimethylpyridine (DDC) blocked the stimulation of aldosterone mediated by adrenocorticotropin (ACTH). Addition of hemin after treatment with DDC partially restored ACTH action. These results suggest that hemin may play a role in regulation of aldosterone production.
