This study examined the involvement of sulphoconjugation in the biosynthesis of the 16-androstene steroids in Leydig cells of the mature boar, since the formation of steroid sulphoconjugates can reduce the levels of these steroids that accumulate in

The effects of glutamate and somatostatin-14 (SRIF) on the in vitro basal and cAMP-stimulated steroid production of mid-vitellogenic rainbow trout (Oncorhynchus mykiss) ovarian follicles were investigated. cAMP-stimulation was achieved by the additio

The objective of the study was to investigate the impact of aryl hydrocarbon receptor (AhR) activation on interrenal steroidogenesis in rainbow trout. To this end, fish were fed AhR agonist (beta-naphthoflavone (BNF): 10 mg/kg body mass/day) and anta

Because estradiol (E(2)) production by the early equine conceptus is considered crucial to the establishment of pregnancy, the amounts of E(2), estrone (E(1)), and their sulfates (E(2)S, E(1)S) were measured by RIA in yolk-sac fluid of 63 conceptuses

The effect of cortisol on the in vitro metabolism of [3H]17-hydroxyprogesterone ([3H]17OHP) was studied during embryonic development of Arctic charr (Salvelinus alpinus) and rainbow trout (Oncorhynchus mykiss). In the absence of cortisol, rainbow tro

By means of high performance liquid chromatography and gas chromatography-mass spectrometry it has been found that 5 alpha-androstane-3 beta,17 beta-diol sulfate and 3 beta-hydroxy-5 alpha-androstan-17-one sulfate (epiandrosterone) are major secretor

The metabolism of 19-norandrostenedione and [3H] 19-nortestosterone was examined in porcine Leydig cell preparations in the absence, or presence, of a 4-azasteroid inhibitor of 5 alpha-reductase. Evidence for a major production of 5 alpha-estrane-3 b
