1 Differential modulation of ACTH-stimulated cortisol and androstenedione secretion by insulin. Androstenedione insulin Bos taurus
2 In contrast, insulin exhibited biphasic effects on the secretion of androstenedione by cells maintained in the presence of ACTH for 24 h; an effect that was most dramatic in the presence of a maximal concentration of ACTH. Androstenedione insulin Bos taurus
3 At an insulin concentration of 0.1 ng/ml, androstenedione secretion by cells maintained in the presence of 10 nM ACTH was increased approximately 2.5-fold. Androstenedione insulin Bos taurus
4 At higher concentrations of insulin, ACTH-stimulated androstenedione secretion was inhibited to an extent comparable to that in cortisol secretion. Androstenedione insulin Bos taurus
5 The effects of insulin on ACTH-stimulated cortisol and androstenedione secretion could not be accounted for by changes in steroid degradation or a loss in 11 beta-hydroxylase activity. Androstenedione insulin Bos taurus
