Steroidogenesis in the yellow corpuscles (adrenocortical homolog) in a holostean fish, the bowfin, Amia calva L.
Yellow corpuscles from the ventral surface of the anterior kidney in bowfins (Amia calva L.) converted [7-3H]pregnenolone to radioactive 11-deoxycortisol, cortisol, and corticosterone in vitro. Aldosterone was not detected. Cortisol was the predominant steroid at the end of a 3-hr incubation period (20 degrees C). These experiments are the first to demonstrate steroidogenesis in holostean yellow bodies and they are the first incubations with pure adrenocortical tissue, free of head kidney, in any bony fish. White corpuscles of Stannius located along the total length of the kidneys were incubated under identical conditions but adrenocortical steroids were not found.
