Recent studies have shown that chronic hypoxia exposure impairs reproduction in fish by interfering with endocrine function, although the mechanisms of endocrine disruption remain unclear. The effects of chronic exposure (4 or 10 weeks) to hypoxia (dissolved oxygen, DO: 1.7

Acne vulgaris is a disorder of the pilosebaceous unit in which the androgens contribute to its onset and persistence. The use of antiandrogens is therefore potentially effective; however, antiandrogens for topical use are not available on the market. Cortexolone 17α-propionate

The existence of direct progestin actions on teleost sperm to stimulate hypermotility is not widely acknowledged because it has only been demonstrated in members of the family Sciaenidae. In the present study, progestin stimulation of sperm hypermotility was investigated in

Corticosteroid hormones are critical for controlling metabolism, hydromineral balance, and the stress response in vertebrates. Although corticosteroid hormones have been well characterized in most vertebrate groups, the identity of the earliest vertebrate corticosteroid hormone has remained elusive. Here we provide

Adrenal steroid profiling, including 17α-OH progesterone (17OHP), 11-deoxycortisol (S), Δ4-androstenedione (Δ4-A) and cortisol (F) in blood spots by tandem mass spectrometry, is used for newborn screening to detect congenital adrenal hyperplasia (CAH). Pre-analytical sample processing is critical for assay specificity

The serum of Atlantic sea lamprey, a basal vertebrate, contains two corticosteroids, 11-deoxycortisol and deoxycorticosterone. Only 11-deoxycortisol has high affinity [K(d) ~ 3 nM] for the corticoid receptor [CR] in lamprey gill cytosol. To investigate the binding of 11-deoxycortisol to

To determine whether the time of day at which corticotropin stimulation testing is performed influences the steroid concentrations observed in persons with normal adrenal function. In this retrospective, secondary analysis, participants with normal adrenal function were studied to determine whether

Although much is known about the increased levels of the 21-hydroxylase substrates 17-hydroxyprogesterone (17OHP) and 21-deoxycortisol (21DF) - the biochemical markers of all forms of 21-hydroxylase deficiency (21OHD), only limited information is available on the zona fasciculata (ZF) products distal

Hormone research in paediatrics, 74(5), 358-364 (2010-07-08)
Relative adrenocortical insufficiency is often seen in sick premature newborns. As the human fetal adrenal cortex does not express the 3β-hydroxysteroid dehydrogenase (3β-HSD) enzyme before about 23 weeks of gestation, we hypothesized that this enzymatic step may be rate limiting

Systemic injection of high doses of 11-deoxycortisol succinate had been reported to induce status epilepticus in rats and cats that was associated with paroxysmal epileptiform activity refractory to first generation antiepileptic drugs (AEDs). Using patch clamp recordings we have investigated

Regio- and stereospecificity of microbial hydroxylation was studied at the transformation of 3-keto-4-ene steroids of androstane and pregnane series by the filamentous fungus of Curvularia lunata VKMF-644. The products of the transformations were isolated by column chromatography and identified using

21-Hydroxylase deficiency (21-OHD) is the target disease of newborn screening for congenital adrenal hyperplasia (CAH). We describe the additional detection of patients suffering from 11β-hydroxylase deficiency (11-OHD) by second-tier testing. Over a period of 5 years, screening for CAH was

Although there is substantial evidence that membrane progestin receptors (mPRs) perform a critical physiological role in meiotic maturation of fish oocytes, it is unknown whether they are also intermediaries in progestin signaling in the surrounding follicular cells. Here, we show

The antifungal agent ketoconazole is often used to suppress cortisol production in patients with Cushing's syndrome (CS). However, ketoconazole has serious side effects and is hepatotoxic. Here, the in vitro effects of ketoconazole and fluconazole, which might be less toxic

Congenital adrenal hyperplasia caused by classic 21-hydroxylase deficiency (21OHD) is an autosomal recessive disorder with a high prevalence of asymptomatic heterozygote carriers (HTZ) in the general population, making case detection desirable by routine methodology.
