Abstract

Immunohistochemistry of human aldosterone synthase (CYP11B2)has revealed that most of aldosterone is autonomously produced in aldosterone-producing cell clusters (APCCs)beneath the capsule of adult adrenals rather than physiologically in the zona glomerulosa (ZG). APCCs have been occasionally found to harbor a somatic mutation of ion channel/pump genes, and number and size of APCCs increase with age until 50 years old. Herein, the objective of the study was to examine APCC development in 106 autopsied adrenals from 85 elderly individuals who died at ages from 50 to 103 years. We obtained the following results: (1)physiological CYP11B2 expression in ZG were attenuated in more elderly persons; (2)number and size of APCCs decreased with age; (3)detachment of APCC from the capsule appeared to occur occasionally over the wide range of the ages; and (4)incidental micro aldosterone-producing adenomas (APAs)and possible APCC-to-APA transitional lesions (pAATLs)were found primarily in samples from persons aged 50–60 years but not in samples from more elderly persons; pAATL was a putative designation based on our previous results indicating that it consisted of subcapsular APCC-like portion and inner APA-like portions. Thus, the formation of the CYP11B2-expressing lesions as well as thickening of the ZG in the adrenals were inversely correlated with age of death in the individuals aged over 50 years. Considering that autopsy samples were used in this study, inactive production of aldosterone regardless of autonomous or physiological manners may have survival advantages in individuals aged over 50 years.
