A kinetic study of corticosterone recovered during incubation of rat adrenal tissue with [4-14C]progesterone and [16-3H]pregnenolone shows that both its 3H: 14C ratio and its specific activity change with time throughout incubation. Corticosterone is itself metabolized, and hypotheses based on the rate of production of corticosterone may be therefore deceptive when the amount is measured at a single point in time. Thus disparities between the specific activities of products and intermediates may be expected which alone do not necessarily indicate differences between the biosynthetic pathways involved in production from endogenous precursors and those from added radioactive precursors.
Other experiments suggest that steroids in incubation media, in concentrations comparable with those found in adrenal venous plasma, do not inhibit the continued synthesis of hormones.
Journal of Endocrinology is committed to supporting researchers in demonstrating the impact of their articles published in the journal.
The two types of article metrics we measure are (i) more traditional full-text views and pdf downloads, and (ii) Altmetric data, which shows the wider impact of articles in a range of non-traditional sources, such as social media.
