cortodoxone and 11-hydroxyandrostenedione

Forty depressed patients and 36 age- and sex-matched controls were given 250 micrograms ACTH1-24 by IV bolus. Plasma steroid hormone levels were measured prior to and 60 min after ACTH administration. The depressed patients had significantly greater cortisol (F), 11-deoxycortisol (S), androstenedione (AD), and 17 alpha-hydroxyprogesterone (17 alpha-OHP) responses (delta; p less than 0.05) and a marginally greater 11 beta-hydroxyandrostenedione (11 beta-OHAD) response (delta; p = 0.091) than the controls. There was no significant difference in the corticosterone (B) response between the two groups. With the exception of 11 beta-OHAD, all the steroid hormones were significantly negatively correlated with age in the controls, but only S and AD marginally demonstrated this relationship in the depressed patients. F, S, AD, 17 alpha-OHP, and B, but not 11 beta-OHAD, were significantly positively correlated with each other in the controls, but only F was significantly correlated with AD in the depressed patients. These data suggest that the hypercortisolemia found in some depressed patients involves increased precursor and metabolite levels both at baseline and in response to exogenous ACTH, compared to controls. Furthermore, variability in these precursors is greater in depressed patients, and their relationship to age is lost. These findings are consistent with the hypothesis that adrenal products other than cortisol also could be related to affective symptoms.

11α-Hydroxyprogesterone (11αOHP4) and 11β-hydroxyprogesterone (11βOHP4) have been reported to be inhibitors of 11β-hydroxysteroid dehydrogenase (11βHSD) type 2, together with 11β-hydroxytestosterone and 11β-hydroxyandrostenedione, and their C11-keto derivatives being inhibitors of 11βHSD1. Our in vitro assays in transiently transfected HEK293 cells, however, show that 11αOHP4 is a potent inhibitor of 11βHSD2 and while this steroid does not serve as a substrate for the enzyme, the aforementioned C11-oxy steroids are indeed substrates for both 11βHSD isozymes. 11βOHP4 is metabolised by 11βHSD2 yielding 11-ketoprogesterone with 11βHSD1 catalysing the reverse reaction, similar to the reduction of the other C11-oxy steroids. In the same model system, novel 11αOHP4 metabolites were detected in its conversion by steroid-5α-reductase (SRD5A) types 1 and 2 yielding 11α-hydroxydihydroprogesterone and its conversion by cytochrome P450 17A1 (CYP17A1) yielding the hydroxylase product, 11α,17α-dihydroxyprogesterone, and the 17,20 lyase product, 11α-hydroxyandrostenedione. We also detected both 11αOHP4 and 11βOHP4 in prostate cancer tissue- ∼23 and ∼32 ng/g respectively with 11KP4 levels >300 ng/g. In vitro assays in PC3 and LNCaP prostate cancer cell models, showed that the metabolism of 11αOHP4 and 11βOHP4 was comparable. In LNCaP cells expressing CYP17A1, 11αOHP4 and 11βOHP4 were metabolised with negligible substrate, 4%, remaining after 48 h, while the steroid substrate 11β,17α-dihydroxyprogesterone (21dF) was metabolised to C11-keto C

Patients with 21-hydroxylase deficiency (21OHD) have long-term complications, resulting from poor disease control and/or glucocorticoid overtreatment. Lack of optimal biomarkers has made it challenging to tailor therapy and predict long-term outcomes.. To identify biomarkers of disease control and long-term complications in 21OHD.. Cross-sectional study of 114 patients (70 males), ages 2 to 67 years (median, 15 years), seen in a tertiary referral center.. We correlated a mass-spectrometry panel of 23 steroids, obtained before first morning medication, with bone age advancement (children), adrenal volume (adults), testicular adrenal rest tumors (TART), hirsutism, menstrual disorders, and pituitary hormones.. Total adrenal volume correlated positively with 18 steroids, most prominently 21-deoxycortisol and four 11-oxygenated-C19 (11oxC19) steroids: 11β-hydroxyandrostenedione (11OHA4), 11-ketoandrostenedione (11ketoA4), 11β-hydroxytestosterone (11OHT), and 11-ketotestosterone (11ketoT) (r ≈ 0.7, P < 0.0001). Nine steroids were significantly higher (P ≤ 0.01) in males with TART compared with those without TART, including 11OHA4 (6.8-fold), 11OHT (4.9-fold), 11ketoT (3.6-fold), 11ketoA4 (3.3-fold), and pregnenolone sulfate (PregS; 4.8-fold). PregS (28.5-fold) and 17-hydroxypregnenolone sulfate (19-fold) levels were higher (P < 0.01) in postpubertal females with menstrual disorders. In males, testosterone levels correlated positively with all 11oxC19 steroids in Tanner stages 1 and 2 (r ≈ 0.7; P < 0.001) but negatively in Tanner stage 5 (r = -0.3 and P < 0.05 for 11ketoA4 and 11ketoT). In females, testosterone level correlated positively with all four 11oxC19 steroids across all Tanner stages (r ≈ 0.8; P < 0.0001).. 11oxC19 steroids and PregS might serve as clinically useful biomarkers of disease control and long-term complications in 21OHD.

Transforming growth factor beta1 (TGFbeta1) has been shown to exert strong inhibitory effects on adrenocortical cell steroidogenesis. However, the molecular targets of TGFbeta1 in adrenocortical cells appear to differ between species. Here, we report the first characterization of the regulatory effects of TGFbeta1 on the steroidogenic functions of the human adrenocortical tumor cell line NCI-H295R. After treatment with 2 ng/ml TGFbeta1 for 24 h, basal production of corticosterone, cortisol and androstenedione was dramatically decreased. When TGFbeta1 was added simultaneously with forskolin, the production of cortisol and 11-hydroxyandrostenedione was decreased by 85% whereas that of deoxycortisol was increased. When TGFbeta1 was added simultaneously with angiotensin II, aldosterone production was reduced by 80%. We observed that TGFbeta1 strongly inhibits forskolin-induced steroid 11beta-hydroxylase activity and CYP11B1 mRNA levels, as well as angiotensin II-induced aldosterone synthase activity and CYP11B2 mRNA levels. CYP11B1 and CYP11B2 gene products thus appear as the major steroidogenic enzymes down-regulated by TGFbeta1 in the human adrenocortical tumor cell line NCI-H295R.

We developed and validated a coordinated set of RIAs for the following eight steroids in single small aliquots (< or = 1 mL) of plasma: androstenedione, dehydroepiandrosterone, 11-deoxycortisol, 21-deoxycortisol (21-DF), 11 beta-hydroxyandrostenedione, 17 alpha-hydroxypregnenolone (17-Hpreg), 17 alpha-hydroxyprogesterone, and testosterone. Samples were extracted and then chromatographed on celite microcolumns. Radioiodinated tracers were used for two of the assays (17-Hpreg and 21-DF). Tritiated tracers and scintillation proximity assay counting were used to give separation-free procedures for the other six assays, which considerably improved their practicability and reproducibility. The basal and postadrenocorticotropic hormone plasma values for these steroids in normal women sampled in the follicular phase are presented. Finally, the measurement of the eight steroids as a diagnostic method is evaluated with reference to data from 203 patients with hirsutism and (or) acne.

The HPLC system was used to separate and measure 10 kinds of corticoids in adrenal tissues. Calibration curves were drawn as straight lines that ranged from 1.25 to 20ng, or 1.25 to 200ng by peak area calculated with the chromatointegrator. The samples for the assay were extracted from homogenized tissues and treated with methanol to remove non-steroidal contaminants which may interfere with the ultraviolet absorption monitor. The recovery rate during the assay procedure was calculated using testosterone as the internal standard, because testosterone was not detected in any adrenal tissue examined in the present study. Contents of corticoids were measured in normal adrenal glands obtained during radical nephrectomy for renal cancer and in functioning adrenal adenomas. Steroid levels in the adrenal glands and tumors have been measured by radioimmunoassay until now, and the data obtained in the present study were compared with those in previous reports. Main steroids in normal adrenals were cortisol (F) and corticosterone (B), and there were certain amounts of 11-deoxycortisol (S), 11-deoxycorticosterone (DOC) and precursor steroids. 11 beta-hydroxy-androstenedione was the main androgen in the adrenal gland. Mineralocorticoids other than B and DOC were very low in the normal adrenals. There was a certain balance between the production of cortisol and corticosterone in normal adrenals. In functioning adenomas, the levels of F, B and aldosterone, and F to B ratios (F/B) varied according to their biological features. Although with the HPLC system it was possible to obtain the production balance of each steroid clearly in the chromatogram, we could not detect the delta 5-3 hydroxysteroids such as pregnenolone and dehydroepiandrosterone using the ultraviolet absorption monitor.

A six-month-old 46,XY infant with a female phenotype and ambiguous genitalia was evaluated for male pseudohermaphroditism. The principal findings were (1) low basal plasma levels of all measured C19 steroids and their sulfates, which were unchanged or only minimally increased after stimulation with human chorionic gonadotropin or ACTH, (2) no urinary metabolites of C19 11-deoxy steroids, and decreased amounts of C19 11-oxosteroids, (3) normal basal plasma cortisol levels and normal urinary excretion of cortisol metabolites, (4) high plasma corticosterone and deoxycorticosterone levels and elevated urinary excretion of their metabolites, (5) high plasma progesterone and pregnenolone levels and increased urinary excretion of pregnanediol and pregnenediol, (6) high plasma 17 alpha-hydroxyprogesterone and 21-deoxycortisol levels and increased urinary excretion of pregnanetriol, 17 alpha-hydroxypregnanolone, and pregnenetriolone, (7) high plasma and urinary levels of 5-pregnene-3 beta,20 alpha-diol sulfate, (8) low plasma levels of 21-hydroxy-pregnenolone and 5-pregnene-3 beta,17 alpha, 20 alpha-triol sulfate, (9) high plasma ACTH levels, and (10) suppression of the high plasma steroid levels by dexamethasone. The unusual pattern of plasma and urinary steroids indicated that this child had multiple abnormalities of steroid-biosynthetic microsomal mixed-function oxidases--21-hydroxylase, 17 alpha-hydroxylase, and 17,20 desmolase. The deficit in the activities of the first two enzymes resulted in decreased cortisol synthesis with subsequent increased ACTH secretion and adrenocortical hyperplasia. The male pseudohermaphroditism resulted from deficient testosterone synthesis due to deficiency of 17 alpha-hydroxylase and 17,20 desmolase. The mother and two sisters of the affected child had evidence of mild 17 alpha-hydroxylase deficiency.
