Why the study?
Do ACTH, angiotensins I and II, increased potassium, and decreased sodium concentrations stimulate steroidogenesis and alter cyclic AMP levels in beef adrenal tissue slices?
Population
Beef adrenal tissue slices (outer slices of 16-20 fresh beef adrenal glands, divided into 500-mg portions)
Comparison
Adrenocorticotropin, angiotensins I and II… vs Control incubations
Design
Preclinical
Follow-up
15 min to 2 hours (incubation time)

Delineates distinct adrenal steroidogenic pathways in bovine tissue; leaves open human translation and targeted interventions.
Do ACTH, angiotensins I and II, increased potassium, and decreased sodium concentrations stimulate steroidogenesis and alter cyclic AMP levels in beef adrenal tissue slices?
This preclinical study demonstrates that ACTH and potassium stimulate adrenal steroidogenesis via cyclic AMP, whereas angiotensin I and II utilize a different mechanism, and decreased sodium acts at a later step in the biosynthetic pathway.
Saruta et al. (1972) studied this question.
