This enzyme, encoded by CYP11B1 gene, is important in the synthesis of CORTICOSTERONE and HYDROCORTISONE. Defects in CYP11B1 cause congenital adrenal hyperplasia (ADRENAL HYPERPLASIA, CONGENITAL).Corticosterone: An adrenocortical steroid that has modest but significant activities as a mineralocorticoid and a glucocorticoid. (From Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed, p1437)Aldosterone: A hormone secreted by the ADRENAL CORTEX that regulates electrolyte and water balance by increasing the renal retention of sodium and the excretion of potassium.Aldosterone Synthase: A mitochondrial cytochrome P450 enzyme that catalyzes the 18-hydroxylation of steroids in the presence of molecular oxygen and NADPH-specific flavoprotein. This enzyme, encoded by CYP11B2 gene, is important in the conversion of CORTICOSTERONE to 18-hydroxycorticosterone and the subsequent conversion to ALDOSTERONE.Hyperaldosteronism: A condition caused by the overproduction of ALDOSTERONE. It is characterized by sodium retention and potassium excretion with resultant HYPERTENSION and HYPOKALEMIA.Desoxycorticosterone: A steroid metabolite that is the 11-deoxy derivative of CORTICOSTERONE and the 21-hydroxy derivative of PROGESTERONE.Hypothyroidism: A syndrome that results from abnormally low secretion of THYROID HORMONES from the THYROID GLAND, leading to a decrease in BASAL METABOLIC RATE. In its most severe form, there is accumulation of MUCOPOLYSACCHARIDES in the SKIN and EDEMA, known as MYXEDEMA.Thyroxine: The major hormone derived from the thyroid gland. Thyroxine is synthesized via the iodination of tyrosines (MONOIODOTYROSINE) and the coupling of iodotyrosines (DIIODOTYROSINE) in the THYROGLOBULIN. Thyroxine is released from thyroglobulin by proteolysis and secreted into the blood. Thyroxine is peripherally deiodinated to form TRIIODOTHYRONINE which exerts a broad spectrum of stimulatory effects on cell metabolism.Congenital Hypothyroidism: A condition in infancy or early childhood due to an in-utero deficiency of THYROID HORMONES that can be caused by genetic or environmental factors, such as thyroid dysgenesis or HYPOTHYROIDISM in infants of mothers treated with THIOURACIL during pregnancy. Endemic cretinism is the result of iodine deficiency.

In humans, the unborn young from the end of the eighth week after CONCEPTION until BIRTH, as distinguished from the earlier EMBRYO, MAMMALIAN.Adrenal Cortex: The outer layer of the adrenal gland. It is derived from MESODERM and comprised of three zones (outer ZONA GLOMERULOSA, middle ZONA FASCICULATA, and inner ZONA RETICULARIS) with each producing various steroids preferentially, such as ALDOSTERONE; HYDROCORTISONE; DEHYDROEPIANDROSTERONE; and ANDROSTENEDIONE. Adrenal cortex function is regulated by pituitary ADRENOCORTICOTROPIN.Adrenocorticotropic Hormone: An anterior pituitary hormone that stimulates the ADRENAL CORTEX and its production of CORTICOSTEROIDS. ACTH is a 39-amino acid polypeptide of which the N-terminal 24-amino acid segment is identical in all species and contains the adrenocorticotrophic activity. Upon further tissue-specific processing, ACTH can yield ALPHA-MSH and corticotrophin-like intermediate lobe peptide (CLIP).Adrenal Gland Neoplasms: Tumors or cancer of the ADRENAL GLANDS.Adenoma: A benign epithelial tumor with a glandular organization.Reproducibility of Results: The statistical reproducibility of measurements (often in a clinical context), including the testing of instrumentation or techniques to obtain reproducible results. The concept includes reproducibility of physiological measurements, which may be used to develop rules to assess probability or prognosis, or response to a stimulus; reproducibility of occurrence of a condition; and reproducibility of experimental results.Sensitivity and Specificity: Binary classification measures to assess test results. Sensitivity or recall rate is the proportion of true positives. Specificity is the probability of correctly determining the absence of a condition. (From Last, Dictionary of Epidemiology, 2d ed)Retinal Neoplasms: Tumors or cancer of the RETINA.Chromatography, Liquid: Chromatographic techniques in which the mobile phase is a liquid.Tandem Mass Spectrometry: A mass spectrometry technique using two (MS/MS) or more mass analyzers. With two in tandem, the precursor ions are mass-selected by a first mass analyzer, and focused into a collision region where they are then fragmented into product ions which are then characterized by a second mass analyzer. A variety of techniques are used to separate the compounds, ionize them, and introduce them to the first mass analyzer. For example, for in GC-MS/MS, GAS CHROMATOGRAPHY-MASS SPECTROMETRY is involved in separating relatively small compounds by GAS CHROMATOGRAPHY prior to injecting them into an ionization chamber for the mass selection.Databases, Chemical: Databases devoted to knowledge about specific chemicals.Databases, Pharmaceutical: Databases devoted to knowledge about PHARMACEUTICAL PRODUCTS.Kidney: Body organ that filters blood for the secretion of URINE and that regulates ion concentrations.Pharmacological Processes: The metabolism of drugs and their mechanisms of action.Electrolytes: Substances that dissociate into two or more ions, to some extent, in water.

(Grant & Hackh's Chemical Dictionary, 5th ed)Adrenocortical Adenoma: A benign neoplasm of the ADRENAL CORTEX. It is characterized by a well-defined nodular lesion, usually less than 2.5 cm. Most adrenocortical adenomas are nonfunctional. The functional ones are yellow and contain LIPIDS. Depending on the cell type or cortical zone involved, they may produce ALDOSTERONE; HYDROCORTISONE; DEHYDROEPIANDROSTERONE; and/or ANDROSTENEDIONE.Adrenal Cortex Neoplasms: Tumors or cancers of the ADRENAL CORTEX.Cushing Syndrome: A condition caused by prolonged exposure to excess levels of cortisol (HYDROCORTISONE) or other GLUCOCORTICOIDS from endogenous or exogenous sources. It is characterized by upper body OBESITY; OSTEOPOROSIS; HYPERTENSION; DIABETES MELLITUS; HIRSUTISM; AMENORRHEA; and excess body fluid. Endogenous Cushing syndrome or spontaneous hypercortisolism is divided into two groups, those due to an excess of ADRENOCORTICOTROPIN and those that are ACTH-independent.Zona Glomerulosa: The narrow subcapsular outer zone of the adrenal cortex. This zone produces a series of enzymes that convert PREGNENOLONE to ALDOSTERONE. The final steps involve three successive oxidations by CYTOCHROME P-450 CYP11B2.Mineralocorticoids: A group of CORTICOSTEROIDS primarily associated with water and electrolyte balance. This is accomplished through the effect on ION TRANSPORT in renal tubules, resulting in retention of sodium and loss of potassium. Mineralocorticoid secretion is itself regulated by PLASMA VOLUME, serum potassium, and ANGIOTENSIN II.Receptors, Mineralocorticoid: Cytoplasmic proteins that specifically bind MINERALOCORTICOIDS and mediate their cellular effects. The receptor with its bound ligand acts in the nucleus to induce transcription of specific segments of DNA.Cholestanetriol 26-Monooxygenase: An NAPH-dependent cytochrome P450 enzyme that catalyzes the oxidation of the side chain of sterol intermediates such as the 27-hydroxylation of 5-beta-cholestane-3-alpha,7-alpha,12-alpha-triol.Adrenal Insufficiency: Conditions in which the production of adrenal CORTICOSTEROIDS falls below the requirement of the body. Adrenal insufficiency can be caused by defects in the ADRENAL GLANDS, the PITUITARY GLAND, or the HYPOTHALAMUS.Thyroid (USP): A dehydrated extract of thyroid glands from domesticated animals.

Aldosterone synthase deficiency type I with no documented homozygous mutations in the CYP11B2 gene. (1/16)

This case report concerns a girl born from non-consanguineous parents and hospitalized in another hospital at the age of 14 days because of a severe salt-losing syndrome (Na=125, K=8.6 mEq/l). In spite of normal genitalia, diagnosis of 21-hydroxylase deficiency was assessed on the basis of a slightly increased 17-OH-progesterone serum level (6.4 ng/ml). The onset of both hydrocortisone and 9alpha-fluorohydrocortisone therapy was followed by a resolution of the clinical picture. At the age of 60 days she was admitted to our clinic for a re-evaluation of the diagnosis. Steroid hormone serum levels were measured after withdrawal of therapy and diagnosis of corticosterone methyl oxidase (CMO) deficiency type I was definitely established in the light of the biochemical results: i.e. very low 18-hydroxycorticosterone (18-OH-B) serum levels (20 pg/ml), an abnormally high corticosterone/18-OH-B serum ratio (306.5) and an abnormally low 18-OH-B/aldosterone serum ratio (2.1). This autosomal recessively inherited disorder can be differentiated from CMO type II and other salt-wasting syndromes only on the basis of the serum steroid hormone pattern. After establishing the diagnosis of CMO I deficiency, hydrocortisone therapy was withdrawn whilst treatment with 9alpha-fluorohydrocortisone was begun again, with a satisfactory clinical and metabolic impact. Direct sequences of the patient's DNA were able to identify only a (heterozygous) amino acid substitution in exon 7 of that gene, which is known to have only a small effect on enzyme activity and cannot be the only cause of the patient's phenotype: valine-386-alanine (V386A) GTG-->GcG. No homozygous mutations in the CYP11B2 gene were observed. This is the first report of a patient with CMO type I who does not carry any homozygous mutation in the entire CYP11B2 alleles, whereas some cases with no mutations in this gene have already been reported in CMO II. The present study seems to be inconsistent with the previously reported correlation of the phenotype and genotype in CMO type I. A reasonable question that might be raised on the basis of our findings in this case report is whether other genes, apart from CYP11B2, are involved in the regulation of terminal aldosterone synthesis.  (+info)

Mutations in aldosterone synthase gene of Milan hypertensive rats: phenotypic consequences. (2/16)

Using in vitro and in vivo methods, we have demonstrated increased sensitivity of adrenocortical steroidogenesis to ACTH in Milan hypertensive (MHS) compared with normotensive (MNS) rats and have investigated whether this is caused by mutations of steroidogenic enzymes. Genes encoding aldosterone synthase (CYP11B2) and 11beta-hydroxylase (CYP11B1) in MHS and MNS have been cloned and sequenced. Nucleotide 752 (G) in exon 4 of MHS CYP11B2 differs from that of MNS (A); CYP11B1 sequences were identical. The nucleotide 752 mutation caused a Q251R substitution in the amino acid sequence of MHS CYP11B2. The phenotype of MHS CYP11B2 alleles, when expressed in COS-1 cells, differed from that of MNS alleles. The relative activities of the three reactions catalyzed by CYP11B2 (11beta-hydroxylation of deoxycorticosterone, 18-hydroxylation of corticosterone, and dehydrogenation of 18-hydroxycorticosterone) were estimated after incubation of transfected cells with [(14)C]deoxycorticosterone and analysis of radioactivity associated with deoxycorticosterone, corticosterone, 18 hydroxycorticosterone, and aldosterone. Both 11- and 18-hydroxylase activities were lower (19 and 12%, respectively; P < 0.01 and P < 0.05) in cells transfected with MHS compared with MNS alleles, whereas 18-oxidase activity was 42% higher (P < 0.01). To assess the significance of the CYP11B2 mutation in vivo, DNA from F2 hybrid MHS x MNS rats was genotyped. MHS alleles were associated with lower urine volumes in both sexes, lower ventricle weights in male rats, but no difference in systolic or diastolic blood pressures between the sexes. We conclude that a mutation in CYP11B2 may affect aldosterone secretion in MHS; however, under normal environmental circumstances, we were unable to demonstrate any influence of this mutation on blood pressure.  (+info)

Stereological and functional investigations on isolated adrenocortical cells. III. Zona glomerulosa cells of chronically ACTH-treated rats. (3/16)

Prolonged (5 day) treatment of rats with high doses of ACTH caused a significant reduction in the plasma concentration of aldosterone and a notable rise in that of corticosterone. Outer subcapsular (zona glomerulosa [ZG]) adrenocortical cells were isolated, and their morphology and secretory activity was investigated. ACTH pretreatment induced a marked hypertrophy of ZG cells which was coupled with significant increases in the volume of the mitochondrial compartment and in the surface area per cell of mitochondrial cristae and AER tubules, as well as with a striking lipid droplet depletion. Mitochondrial cristae were found to change from a tubulo-laminar to a tubulo-convolute configuration. Despite their hypertrophy, ZG cells from ACTH-pretreated rats displayed a conspicuous decrease in both basal and stimulated overall production of post-pregnenolone steroids, which was ascribed to the depletion of their stores of steroid hormone precursors (i.e. cholesterol and cholesterol esters contained in the lipid droplets). However, both basal and stimulated secretion of aldosterone was doubled, suggesting that chronic ACTH treatment induces in ZG cells an increased availability of monoxygenase II, the enzyme involved in the transformation of 18-hydroxycorticosterone into aldosterone. In the light of these findings, the drop in the plasma level of aldosterone observed in rats after prolonged treatment with ACTH is assumed to be due to an enhanced metabolism of aldosterone, possibly at the hepatic level.  (+info)

Altered responses of plasma 18-hydroxycorticosterone and aldosterone to angiotensin II and adrenocorticotropin in patients with a 18-hydroxycorticosterone-producing tumor. (4/16)

Plasma 18-hydroxycorticosterone (18-OHB) and aldosterone responses to angiotensin II (AII) and ACTH were examined in 2 patients with a 18-OHB-producing tumor (18-OHBPT) versus those in 8 patients with a aldosterone-producing adenoma (APA), 7 patients with low renin essential hypertension (LREH) and 10 normal subjects. Plasma 18-OHB and aldosterone levels and the 18-OHB: aldosterone ratio were high in patients with an APA and normal in patients with LREH. In patients with a 18-OHBPT, plasma 18-OHB and aldosterone levels were high and normal, respectively, resulting in a 2-fold greater 18-OHB: aldosterone ratio than that in patients with an APA. Patients with an APA had a blunted response of plasma 18-OHB and aldosterone to AII and a supranormal response of these corticoids to ACTH. Patients with LREH had a supranormal response of plasma 18-OHB and aldosterone to AII and a normal response of these corticoids to ACTH. In patients with a 18-OHBPT the responses of both plasma 18-OHB and aldosterone to AII and ACTH closely resembled those in patients with an APA but not in patients with LREH. These data suggest that 18-OHBPT may be a variant of aldosteronomas, producing a large amount of 18-OHB and a small amount of aldosterone.  (+info)

Effects of corticotropin-releasing factor (CRF) on aldosterone and 18-hydroxycorticosterone in essential hypertension and primary aldosteronism. (5/16)

The effects of ovine corticotropin releasing factor (o-CRF) on plasma aldosterone, 18-OH-corticosterone (18-OHB), plasma adrenocorticotropin (ACTH) and cortisol were determined in eight patients with primary aldosteronism, six with aldosterone-producing adenoma (APA) and two with idiopathic hyperaldosteronism (IHA). The results were compared with those in six normal subjects and eleven patients with essential hypertension (EHT, 5 with low renin and 6 with normal renin). In patients with APA, the peak plasma aldosterone and 18-OHB responses to 100 micrograms iv of o-CRF (226% and 113% increase from baseline, respectively) were greater than those in EHT and normal subjects. The net integrated aldosterone and 18-OHB responses (840 +/- 156, and 419 +/- 121 ng/dl.hr, respectively) were also significantly greater (p less than 0.01) in APA than those in normals and EHT. In two patients with IHA, both the peak and net integrated aldosterone response were smaller than those in APA, in spite of nearly identical plasma ACTH and cortisol responses. These results suggest that augmented responses of mineralocorticoids to o-CRF may be characteristic of aldosteronism due to APA, mediated by CRF-induced ACTH, and possibly other proopiomelanocortin (POMC)-derived peptides.  (+info)

The renal, cardiovascular and hormonal actions of human atrial natriuretic peptide in man; effects of indomethacin. (6/16)

The renal, cardiovascular and hormonal effects of intravenous infusion of alpha-human atrial natriuretic polypeptides (alpha-hANP) at the concentrations of 0.0125, 0.025, 0.05, 0.1 microgram kg-1 min-1 for 20 min was studied in six male volunteers before and after indomethacin administration (150 mg day-1, three times daily for 3 days). Dose-dependent diuresis and natriuresis were observed in all subjects between the concentrations of 0.025 and 0.1 microgram kg-1 min-1, which were not influenced by indomethacin. Diastolic blood pressure decreased significantly (P less than 0.05) at the higher dose (0.05 microgram kg-1 min-1) of alpha-hANP, which was attenuated by indomethacin pretreatment. The plasma concentration of the immunoreactive alpha-hANP was 73.7 +/- 25 pg ml-1 on the control in subjects taking 200 mEq day-1 of sodium, and significant diuresis occurred when plasma concentration reached approximately 330.5 +/- 74.4 pg ml-1. alpha-hANP infusion caused a dose-dependent increase in cyclic GMP, no significant changes in plasma aldosterone and 18-hydroxycorticosterone, which were not influenced by indomethacin pretreatment. Plasma renin did not change in response to alpha-hANP infusion, which was significantly decreased (P less than 0.05) after indomethacin pretreatment. These results support that the renal effects of alpha-hANP may be exerted by prostaglandin-independent mechanisms. The renal effects occur at lower doses, and cardiovascular changes occur at higher doses of alpha-hANP.  (+info)

An adrenocortical tumor secreting weak mineralocorticoids. (7/16)

An adrenocortical carcinoma (15.5 g) secreting excessive amounts of steroids with weak mineralocorticoid activity in a 25-year-old woman was studied with particular reference to its in vivo and in vitro secretions of steroids. Severe hypertension, occasional low serum potassium and suppressed PRA were the major clinical findings, and were improved with removal of the tumor. In the preoperative stage, plasma levels of 11-deoxycorticosterone, 18-hydroxy-11-deoxycorticosterone, corticosterone and 18-hydroxycorticosterone were all increased. However, the plasma level of aldosterone was repeatedly normal. Although plasma levels of pregnenolone, 17-hydroxypregnenolone, progesterone and 17-hydroxyprogesterone were very high, those of other late step steroids, i.e. 11-deoxycortisol, cortisol, dehydroepiandrosterone, androstenedione and testosterone were almost normal. From these findings, a major etiological role of weak mineralocorticoids such as 11-deoxycorticosterone, 18-hydroxycorticosterone and corticosterone in her hypertension was suggested. Pregnenolone and 17-hydroxypregnenolone in tumor tissue were increased, but 11-deoxycorticosterone, corticosterone, aldosterone, cortisol and adrenal androgens such as dehydroepiandrosterone, androstenedione and testosterone were below normal or low normal. In vitro production of 11-deoxycorticosterone, aldosterone or cortisol by the tumor tissue slices was very low and scarcely responded to synthetic ACTH.  (+info)

Adrenal steroid responses to ACTH in glucocorticoid-suppressible aldosteronism. (8/16)

To investigate adrenal responses to adrenocorticotrophin (ACTH), we infused graded doses of ACTH (1.25 to 20.0 mIU/30 minutes) in normal subjects, patients with low-renin essential hypertension (LREH), primary aldosteronism (PA), and glucocorticoid-suppressible hyperaldosteronism (GSH). Plasma aldosterone, cortisol, corticosterone, and 18-hydroxycorticosterone were measured. The results revealed a greater increase in the plasma aldosterone and 18-hydroxycorticosterone levels evoked by ACTH in the GSH group than in any other group, which suggested enhanced responsiveness of the aldosterone-producing cells to ACTH and a probable adrenal abnormality.  (+info)

Adrenal venous blood was collected from hypophysectomized and sham-hypophysectomized dogs 6 days postoperatively. 17-Hydroxycorticosterone, corticosterone, 11-desoxy-17-hydroxycorticosterone and aldosterone were isolated by paper chromatography. Histological examination of the sellar and suprasellar regions of the hypophysectomized dogs demonstrated the absence of pituitary tissue. The adrenal glands of the hypophysectomized dogs showed cortical atrophy which did not involve the zona glomerulosa. The rate of secretion of aldosterone by the hypophysectomized dogs was found to be approximately 66% of that of the control, sham hypophysectomized, dogs. The rates of secretion of 17-hydroxycorticosterone, corticosterone and 11-desoxy-17-hydroxycorticosterone were found to be approximately 10% of that of the controls. The ability of the hypophysectomized dog to remain in electrolyte balance appears to be due in large measure to the continued secretion of aldosterone.. ...

In this study, the LC-MS/MS intra-assay accuracy and precision were 90% to 111% and 3% to 9% for 18OHF and 18oxoF, respectively. Those of interassay were 87% to 108% and 1% to 10% for 18OHF and 18oxoF, respectively. The lower limits of quantification of 18OHF and 18oxoF were 2.5 and 0.25 ng/dL, respectively. The 3% to 9% precision of LC-MS/MS indicated, therefore, that this method was considered as a reliable mode of measurement in this setting. Further to this, the cut-off value was higher than the lower limit of quantification. Thus, we think that precision of the measurement method was demonstrated by the results obtained. Likewise, the sensitivity and the specificity of the cut-off value were influenced by the precision of the measurement method. Nevertheless, it is entirely true that the 3% to 9% precision of this method indicated that the clinical diagnosis of AP should be carefully performed in patients whose 18OHF and 18oxoF values are around the cut-off value.. 18-Hydroxycorticosterone ...

Cerebral and renal alpha-adrenergic receptors play an important role in the control of blood pressure. We studied alpha-adrenergic receptors in the cerebral and renal cortex of Milan hypertensive strain (MHS) and normotensive strain (MNS) rats, a genetic model of spontaneous hypertension linked to a kidney abnormality. Binding of the selective alpha 1-adrenergic antagonist [3H]prazosin and the alpha 2-adrenergic antagonist [3H]rauwolscine was used for receptor studies in tissues of prehypertensive (24-day-old) and hypertensive (60-day-old) rats. In the cerebral cortex, no between-strain differences in alpha 1-adrenergic and alpha 2-adrenergic receptor density and affinity were observed in prehypertensive and hypertensive periods. The density of these receptors increased similarly with age in MHS and MNS rats. In the renal cortex, the differences between MHS and MNS rats concerned alpha 2-adrenergic receptors only. Compared with their age-matched normotensive controls, MHS rats showed 1) a lower ...

In this investigation we found that little of intravenously infused [14C]deoxycorticosterone (DOC) was converted to [14C]DOC-SO4 that entered plasma. Moreover little of intravenously infused [3H]DOC-SO4 was metabolized by way of DOC except by intestinal bacterial enzymes. However evidence was obtained that plasma DOC is converted to DOC-SO4 in liver, but little of the DOC-SO4 formed in liver escapes into blood; rather the DOC-SO4 enters bile and in the intestine is converted, in part, to progesterone (or metabolites thereof) by the action of bacterial enzymes. The estimated intrahepatic fractional conversion of DOC to DOC-SO4 was significantly greater in premenopausal women (0.72 +/- 0.118, mean +/- SEM) than in men (0.28 +/- 0.036, P less than 0.005).. ...

Understanding the kinetics of aromatic-DNA adducts in target tissues and white blood cells (WBC) would enhance the applicability of DNA adducts in WBC as surrogate source of DNA in biomonitoring studies. In the present study, rats were acutely exposed to benzo[a]pyrene (B[a]P; 10 mg/kg body wt) via intratracheal (i.t.), dermal and oral administration. DNA adducts were analyzed in relevant target organs and WBC by nuclease P1 enriched 32P-post-labeling at 1, 2, 4, 11 and 21 days after exposure. Additionally, the internal dose was assessed by measurement of urinary excretion of 3-hydroxy-B[a]P (3-OH-B[a]P). Total B[a]P-DNA adduct levels in WBC were highest after i.t. and oral administration, whereas DNA adducts were hardly detectable after dermal exposure.
