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.
Adrenal Glands
Adrenal Medulla
The inner portion of the adrenal gland. Derived from ECTODERM, adrenal medulla consists mainly of CHROMAFFIN CELLS that produces and stores a number of NEUROTRANSMITTERS, mainly adrenaline (EPINEPHRINE) and NOREPINEPHRINE. The activity of the adrenal medulla is regulated by the SYMPATHETIC NERVOUS SYSTEM.
Zona Reticularis
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).
Zona Fasciculata
Cerebral Cortex
Adrenal Insufficiency
Prefrontal Cortex
The rostral part of the frontal lobe, bounded by the inferior precentral fissure in humans, which receives projection fibers from the MEDIODORSAL NUCLEUS OF THE THALAMUS. The prefrontal cortex receives afferent fibers from numerous structures of the DIENCEPHALON; MESENCEPHALON; and LIMBIC SYSTEM as well as cortical afferents of visual, auditory, and somatic origin.

Zona Glomerulosa
Steroid 11-beta-Hydroxylase
A mitochondrial cytochrome P450 enzyme that catalyzes the 11-beta-hydroxylation of steroids in the presence of molecular oxygen and NADPH-FERRIHEMOPROTEIN REDUCTASE. 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).
Motor Cortex
Area of the FRONTAL LOBE concerned with primary motor control located in the dorsal PRECENTRAL GYRUS immediately anterior to the central sulcus. It is comprised of three areas: the primary motor cortex located on the anterior paracentral lobule on the medial surface of the brain; the premotor cortex located anterior to the primary motor cortex; and the supplementary motor area located on the midline surface of the hemisphere anterior to the primary motor cortex.
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 Function Tests
Adrenocortical Carcinoma
A malignant neoplasm of the ADRENAL CORTEX. Adrenocortical carcinomas are unencapsulated anaplastic (ANAPLASIA) masses sometimes exceeding 20 cm or 200 g. They are more likely to be functional than nonfunctional, and produce ADRENAL CORTEX HORMONES that may result in hypercortisolism (CUSHING SYNDROME); HYPERALDOSTERONISM; and/or VIRILISM.
Auditory Cortex
Adrenal Hyperplasia, Congenital
A group of inherited disorders of the ADRENAL GLANDS, caused by enzyme defects in the synthesis of cortisol (HYDROCORTISONE) and/or ALDOSTERONE leading to accumulation of precursors for ANDROGENS. Depending on the hormone imbalance, congenital adrenal hyperplasia can be classified as salt-wasting, hypertensive, virilizing, or feminizing. Defects in STEROID 21-HYDROXYLASE; STEROID 11-BETA-HYDROXYLASE; STEROID 17-ALPHA-HYDROXYLASE; 3-beta-hydroxysteroid dehydrogenase (3-HYDROXYSTEROID DEHYDROGENASES); TESTOSTERONE 5-ALPHA-REDUCTASE; or steroidogenic acute regulatory protein; among others, underlie these disorders.

Aldosterone
Adrenodoxin
Hydrocortisone
Corticosterone
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.
Cholesterol Side-Chain Cleavage Enzyme
A mitochondrial cytochrome P450 enzyme that catalyzes the side-chain cleavage of C27 cholesterol to C21 pregnenolone in the presence of molecular oxygen and NADPH-FERRIHEMOPROTEIN REDUCTASE. This enzyme, encoded by CYP11A1 gene, catalyzes the breakage between C20 and C22 which is the initial and rate-limiting step in the biosynthesis of various gonadal and adrenal steroid hormones.
Steroidogenic Factor 1
A transcription factor and member of the nuclear receptor family NR5 that is expressed throughout the adrenal and reproductive axes during development. It plays an important role in sexual differentiation, formation of primary steroidogenic tissues, and their functions in post-natal and adult life. It regulates the expression of key steroidogenic enzymes.
Cattle
Steroid 21-Hydroxylase
An adrenal microsomal cytochrome P450 enzyme that catalyzes the 21-hydroxylation of steroids in the presence of molecular oxygen and NADPH-FERRIHEMOPROTEIN REDUCTASE. This enzyme, encoded by CYP21 gene, converts progesterones to precursors of adrenal steroid hormones (CORTICOSTERONE; HYDROCORTISONE). Defects in CYP21 cause congenital adrenal hyperplasia (ADRENAL HYPERPLASIA, CONGENITAL).
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.
Adrenocortical Hyperfunction
Addison Disease
An adrenal disease characterized by the progressive destruction of the ADRENAL CORTEX, resulting in insufficient production of ALDOSTERONE and HYDROCORTISONE. Clinical symptoms include ANOREXIA; NAUSEA; WEIGHT LOSS; MUSCLE WEAKNESS; and HYPERPIGMENTATION of the SKIN due to increase in circulating levels of ACTH precursor hormone which stimulates MELANOCYTES.
Steroid 17-alpha-Hydroxylase
A microsomal cytochrome P450 enzyme that catalyzes the 17-alpha-hydroxylation of progesterone or pregnenolone and subsequent cleavage of the residual two carbons at C17 in the presence of molecular oxygen and NADPH-FERRIHEMOPROTEIN REDUCTASE. This enzyme, encoded by CYP17 gene, generates precursors for glucocorticoid, androgen, and estrogen synthesis. Defects in CYP17 gene cause congenital adrenal hyperplasia (ADRENAL HYPERPLASIA, CONGENITAL) and abnormal sexual differentiation.

Steroids
A group of polycyclic compounds closely related biochemically to TERPENES. They include cholesterol, numerous hormones, precursors of certain vitamins, bile acids, alcohols (STEROLS), and certain natural drugs and poisons. Steroids have a common nucleus, a fused, reduced 17-carbon atom ring system, cyclopentanoperhydrophenanthrene. Most steroids also have two methyl groups and an aliphatic side-chain attached to the nucleus. (From Hawley's Condensed Chemical Dictionary, 11th ed)
Chromaffin Cells
Cells that store epinephrine secretory vesicles. During times of stress, the nervous system signals the vesicles to secrete their hormonal content. Their name derives from their ability to stain a brownish color with chromic salts. Characteristically, they are located in the adrenal medulla and paraganglia (PARAGANGLIA, CHROMAFFIN) of the sympathetic nervous system.
Dehydroepiandrosterone
A major C19 steroid produced by the ADRENAL CORTEX. It is also produced in small quantities in the TESTIS and the OVARY. Dehydroepiandrosterone (DHEA) can be converted to TESTOSTERONE; ANDROSTENEDIONE; ESTRADIOL; and ESTRONE. Most of DHEA is sulfated (DEHYDROEPIANDROSTERONE SULFATE) before secretion.

Pheochromocytoma
A usually benign, well-encapsulated, lobular, vascular tumor of chromaffin tissue of the ADRENAL MEDULLA or sympathetic paraganglia. The cardinal symptom, reflecting the increased secretion of EPINEPHRINE and NOREPINEPHRINE, is HYPERTENSION, which may be persistent or intermittent. During severe attacks, there may be HEADACHE; SWEATING, palpitation, apprehension, TREMOR; PALLOR or FLUSHING of the face, NAUSEA and VOMITING, pain in the CHEST and ABDOMEN, and paresthesias of the extremities. The incidence of malignancy is as low as 5% but the pathologic distinction between benign and malignant pheochromocytomas is not clear.

Magnetic Resonance Imaging
Hypothalamo-Hypophyseal System
A collection of NEURONS, tracts of NERVE FIBERS, endocrine tissue, and blood vessels in the HYPOTHALAMUS and the PITUITARY GLAND. This hypothalamo-hypophyseal portal circulation provides the mechanism for hypothalamic neuroendocrine (HYPOTHALAMIC HORMONES) regulation of pituitary function and the release of various PITUITARY HORMONES into the systemic circulation to maintain HOMEOSTASIS.
Hypophysectomy
RNA, Messenger
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
Mitochondria
Semiautonomous, self-reproducing organelles that occur in the cytoplasm of all cells of most, but not all, eukaryotes. Each mitochondrion is surrounded by a double limiting membrane. The inner membrane is highly invaginated, and its projections are called cristae. Mitochondria are the sites of the reactions of oxidative phosphorylation, which result in the formation of ATP. They contain distinctive RIBOSOMES, transfer RNAs (RNA, TRANSFER); AMINO ACYL T RNA SYNTHETASES; and elongation and termination factors. Mitochondria depend upon genes within the nucleus of the cells in which they reside for many essential messenger RNAs (RNA, MESSENGER). Mitochondria are believed to have arisen from aerobic bacteria that established a symbiotic relationship with primitive protoeukaryotes. (King & Stansfield, A Dictionary of Genetics, 4th ed)
Adrenarche
A stage of development at which the ADRENAL GLANDS undergo maturation leading to the capability of producing increasing amounts of adrenal androgens, DEHYDROEPIANDROSTERONE and ANDROSTENEDIONE. Adrenarche usually begins at about 7 or 8 years of age before the signs of PUBERTY and continues throughout puberty.

The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.
Neurons
Glucocorticoids
A group of CORTICOSTEROIDS that affect carbohydrate metabolism (GLUCONEOGENESIS, liver glycogen deposition, elevation of BLOOD SUGAR), inhibit ADRENOCORTICOTROPIC HORMONE secretion, and possess pronounced anti-inflammatory activity. They also play a role in fat and protein metabolism, maintenance of arterial blood pressure, alteration of the connective tissue response to injury, reduction in the number of circulating lymphocytes, and functioning of the central nervous system.

Cytochrome P-450 Enzyme System
A superfamily of hundreds of closely related HEMEPROTEINS found throughout the phylogenetic spectrum, from animals, plants, fungi, to bacteria. They include numerous complex monooxygenases (MIXED FUNCTION OXYGENASES). In animals, these P-450 enzymes serve two major functions: (1) biosynthesis of steroids, fatty acids, and bile acids; (2) metabolism of endogenous and a wide variety of exogenous substrates, such as toxins and drugs (BIOTRANSFORMATION). They are classified, according to their sequence similarities rather than functions, into CYP gene families (>40% homology) and subfamilies (>59% homology). For example, enzymes from the CYP1, CYP2, and CYP3 gene families are responsible for most drug metabolism.

Angiotensin II
An octapeptide that is a potent but labile vasoconstrictor. It is produced from angiotensin I after the removal of two amino acids at the C-terminal by ANGIOTENSIN CONVERTING ENZYME. The amino acid in position 5 varies in different species. To block VASOCONSTRICTION and HYPERTENSION effect of angiotensin II, patients are often treated with ACE INHIBITORS or with ANGIOTENSIN II TYPE 1 RECEPTOR BLOCKERS.
Organ Specificity

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.
Chromaffin System
Microscopy, Electron
Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.
Tissue Distribution
Accumulation of a drug or chemical substance in various organs (including those not relevant to its pharmacologic or therapeutic action). This distribution depends on the blood flow or perfusion rate of the organ, the ability of the drug to penetrate organ membranes, tissue specificity, protein binding. The distribution is usually expressed as tissue to plasma ratios.

Cats
The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago. (From Walker's Mammals of the World, 6th ed, p801)
Renin
Nerve Net
A meshlike structure composed of interconnecting nerve cells that are separated at the synaptic junction or joined to one another by cytoplasmic processes. In invertebrates, for example, the nerve net allows nerve impulses to spread over a wide area of the net because synapses can pass information in any direction.
Bucladesine

Hormones
Chemical substances having a specific regulatory effect on the activity of a certain organ or organs. The term was originally applied to substances secreted by various ENDOCRINE GLANDS and transported in the bloodstream to the target organs. It is sometimes extended to include those substances that are not produced by the endocrine glands but that have similar effects.

Microsomes
Artifactual vesicles formed from the endoplasmic reticulum when cells are disrupted. They are isolated by differential centrifugation and are composed of three structural features: rough vesicles, smooth vesicles, and ribosomes. Numerous enzyme activities are associated with the microsomal fraction. (Glick, Glossary of Biochemistry and Molecular Biology, 1990; from Rieger et al., Glossary of Genetics: Classical and Molecular, 5th ed)
Adrenal Rest Tumor
Neoplasm derived from displaced cells (rest cells) of the primordial ADRENAL GLANDS, generally in patients with CONGENITAL ADRENAL HYPERPLASIA. Adrenal rest tumors have been identified in TESTES; LIVER; and other tissues. They are dependent on ADRENOCORTICOTROPIN for growth and adrenal steroid secretion.
Androgens
Compounds that interact with ANDROGEN RECEPTORS in target tissues to bring about the effects similar to those of TESTOSTERONE. Depending on the target tissues, androgenic effects can be on SEX DIFFERENTIATION; male reproductive organs, SPERMATOGENESIS; secondary male SEX CHARACTERISTICS; LIBIDO; development of muscle mass, strength, and power.
Stimulation, Chemical
The increase in a measurable parameter of a PHYSIOLOGICAL PROCESS, including cellular, microbial, and plant; immunological, cardiovascular, respiratory, reproductive, urinary, digestive, neural, musculoskeletal, ocular, and skin physiological processes; or METABOLIC PROCESS, including enzymatic and other pharmacological processes, by a drug or other chemical.
Freeze Etching
A replica technique in which cells are frozen to a very low temperature and cracked with a knife blade to expose the interior surfaces of the cells or cell membranes. The cracked cell surfaces are then freeze-dried to expose their constituents. The surfaces are now ready for shadowing to be viewed using an electron microscope. This method differs from freeze-fracturing in that no cryoprotectant is used and, thus, allows for the sublimation of water during the freeze-drying process to etch the surfaces.
Nuclear bodies are usual constituents in tissues of hibernating dormice. (1/1201)
In previous studies we demonstrated in several tissues of the hazel dormouse Muscardinus avellanarius that during hibernation cell nuclei contain particular structural constituents absent in euthermia. In the present study we examine the same tissues in euthermic and hibernating individuals of the edible dormouse Glis glis in order to investigate possible modifications of nuclear structural constituents occurring during hibernation in this species. Edible dormice were captured in the wild and maintained in an external animal house. Samples of liver, pancreas, brown adipose tissue and adrenal cortex were taken from three hibernating and three euthermic animals and processed for resin embedding. Ultrastructural and immunocytochemical studies were carried out on cell nuclei of these tissues. The most evident feature of cell nuclei of hibernating dormice was the presence of several nuclear bodies, namely fibro-granular material, amorphous bodies, coiled bodies, perichromatin granule-like granules and nucleoplasmic fibrils, the distribution of which was peculiar to each tissue. No one of these constituents was detectable during euthermia. Immunocytochemical analyses revealed that they contain some splicing factors. Apart from some differences, maybe due to the different characteristics of lethargy, the nuclear bodies found in edible dormice were morphologically and immunocytochemically similar to those previously described in the same tissues of hazel dormice. They therefore seem to be strictly correlated to the hibernating state. If they represent storage and/or assembly sites of splicing factors to be rapidly used upon arousal, they could represent a usual structural feature in cells of hibernating species. (+info)Natural killer cell activity in the peripheral blood of patients with Cushing's syndrome. (2/1201)
BACKGROUND: Natural killer (NK) cells are CD3(-)CD16(+)CD56(+) bone-marrow-derived lymphocytes mediating first-line defence by direct cytotoxicity against various types of target cells without prior immunization. NK cell activity is positively regulated by immune interferon (IFN-gamma); among hormones, glucocorticoids are potent in vitro and in vivo inhibitors, whereas ACTH and beta-endorphin in many experimental circumstances enhance NK cytotoxicity. DESIGN: We measured NK cytotoxicity of peripheral blood mononuclear cells (PBMC) obtained at 0800h and 2000h from 26 patients with Cushing's syndrome (12 pituitary-dependent, 12 adrenal-dependent and two dependent on ectopic ACTH secretion). In vitro responsiveness to IFN-gamma or cortisol was also tested. METHODS: NK activity was measured in a 4-h direct cytotoxicity assay using K562 cells as targets. Plasma ACTH, serum and urinary free cortisol were concomitantly measured with commercially available kits. RESULTS: Spontaneous activity and responsiveness to IFN-gamma or cortisol were significantly greater in 15 age- and sex-matched controls than in Cushing's patients at 0800h. In pituitary-dependent Cushing's patients, plasma ACTH correlated positively with mean levels of spontaneous NK activity (r=0.64, P<0.05) and negatively with cortisol-dependent percentage inhibition (r=-0.69, P<0.02). In adrenal-dependent Cushing's patients, a negative correlation was observed between levels of spontaneous NK activity and urinary free cortisol (r=-0.67, P<0.02). CONCLUSIONS: Our data indicate that excess endogenous glucocorticoids affect spontaneous NK cell activity and responsiveness to exogenous IFN-gamma or cortisol. The differential patterns observed between pituitary-dependent and adrenal-dependent groups are compatible with a positive immunomodulatory role of pituitary pro-opiomelanocortin-derived peptides that effectively counterbalance, at least partially, glucocorticoid immunosuppression. (+info)Lipid requirement of membrane-bound 3-oxosteroid delta4-delta5-isomerase. Studies on beef adrenocortical microsomes. (3/1201)
The role of phospholipid in the beef adrenal microsomal 3-oxosteroid delta4-delta5-isomerase (EC 5.3.1.1) has been investigated with the use of phospholipase A to alter the microsomal phospholipids. The byproducts of phospholipase A digestion have been removed with a wash solution containing bovine serum albumin. Removal of 80-85% of the phospholipid leads to loss of 80-90% of the 3-oxosteroid delta4-delta5-isomerase activity. Reconstitution experiments have been performed by introduction of lipid aqueous dispersions in the enzymatic assay. Asolectin, a commercially available preparation of soy phosphatides, is able to stimulate the enzymatic activity but does not restore the 3-oxosteroid delta4-delta5-isomerase activity in phospholipase-A-treated membranes. In contrast, the introduction of aqueous dispersions of microsomal total lipid mixtures in the enzymatic assay brings about a complete restoration of the 3-oxosteroid delta4-delta5-isomerase activity in the lipid-depleted membranes. It is concluded that the bovine adrenal microsomal 3-oxosteroid delta4-delta5-isomerase requires phospholipid(s) to exhibit its full catalytic activity. (+info)Local renin-angiotensin system is involved in K+-induced aldosterone secretion from human adrenocortical NCI-H295 cells. (4/1201)
NCI-H295, a human adrenocarcinoma cell line, has been proposed as a model system to define the role of the renin-angiotensin system in the regulation of aldosterone production in humans. Because the precise cellular localization of the components of the renin-angiotensin system in human adrenal cortical cells remains unclear, we investigated their localization in this defined cell system. NCI-H295 cells expressed both angiotensinogen and renin as shown by reverse transcriptase polymerase chain reaction and immunohistochemistry. Human angiotensin-converting enzyme (ACE) was not detectable by immunocytochemistry, ACE binding, or reverse transcriptase polymerase chain reaction. However, 3.5 mmol/L K+ stimulated the formation of both angiotensin I and angiotensin II 1. 9- and 2.5-fold, respectively, and increased aldosterone release 3. 0-fold. The K+-induced stimulation of aldosterone release was decreased by captopril and enalaprilat (24% and 26%, respectively) and by the angiotensin type 1 (AT1)-receptor antagonist losartan (28%). Angiotensin II-induced stimulation of aldosterone release was abolished by losartan treatment. Specific [125I]Sar1-angiotensin II binding was detected by receptor autoradiography. The binding of [125I]Sar1-angiotensin II was completely displaced by the AT1 antagonist losartan but not by the AT2 receptor ligand PD 123319, confirming the expression of angiotensin II AT1 receptors in NCI-H295 cells. Our results demonstrate that NCI-H295 cells express most of the components of the renin-angiotensin system. Our failure to detect ACE, however, suggests that the production of angiotensin II in NCI-H295 cells may be ACE independent. NCI-H295 cells are able to produce angiotensin II, and K+ increases aldosterone secretion in part through an angiotensin-mediated pathway. The production of angiotensin II in NCI-H295 cells demonstrates that this human cell line can be useful to characterize the role of locally produced angiotensin II in the regulation of aldosterone release. (+info)Comparison of expression and regulation of the high-density lipoprotein receptor SR-BI and the low-density lipoprotein receptor in human adrenocortical carcinoma NCI-H295 cells. (5/1201)
In rodents, cholesterol for adrenal steroidogenesis is derived mainly from high-density lipoproteins (HDL) via the HDL receptor, scavenger receptor-BI (SR-BI). In humans cholesterol for steroidogenesis is considered to be derived from the low-density lipoprotein (LDL) receptor pathway, and the contribution of SR-BI to that is unknown. In the present study SR-BI expression and regulation by steroidogenic stimuli was analysed in human adrenocortical cells and compared with LDL receptor expression. In addition, the functional contribution of both receptors for cholesteryl ester delivery to human adrenocortical cells was compared. Northern blot and reverse transcription-PCR amplification and sequence analysis demonstrated the presence of SR-BI mRNA in foetal and adult human adrenal cortex. Furthermore, SR-BI mRNA was expressed to similar levels in human primary adrenocortical and adrenocortical carcinoma NCI-H295 cells, indicating its presence in the steroid-producing cells. Treatment of NCI-H295 cells with 8Br-cAMP, a stimulator of glucocorticoid synthesis via the protein kinase A second messenger signal transduction pathway, resulted in an increase of both SR-BI and LDL receptor mRNA levels in a time- and dose-dependent manner. The induction of SR-BI and LDL receptor by cAMP was independent of ongoing protein synthesis and occurred at the transcriptional level. Ligand blot experiments indicated that a protein of similar size to SR-BI is the major HDL-binding protein in NCI-H295 cells. Western blot analysis demonstrated that cAMP treatment increased the levels of LDL receptor and, to a lesser extent, SR-BI protein in NCI-H295 cells. Binding and uptake of cholesterol was quantitatively smaller from HDL than from LDL, both in basal as well as in cAMP-stimulated cells. Scatchard analysis under basal conditions indicated that NCI-H295 cells express twice as many specific binding sites for LDL than for HDL. Dissociation constant values (Kd; in nm) were approximately five times higher for HDL than for LDL, indicating a lower affinity of HDL compared with LDL. The combined effects of these two parameters and the low cholesteryl ester content of HDL subfraction 3 (HDL3) contributes to a lower cholesteryl ester uptake from HDL than from LDL by the NCI-H295 cells. In conclusion, both the SR-BI and LDL receptor genes are expressed in the human adrenal cortex and coordinately regulated by activators of glucocorticoid synthesis. In contrast to rodents, in human adrenocortical cells the HDL pathway of cholesterol delivery appears to be of lesser importance than the LDL pathway. Nevertheless, the SR-BI pathway may become of major importance in conditions of functional defects in the LDL receptor pathway. (+info)The expression of inhibin/activin subunits in the human adrenal cortex and its tumours. (6/1201)
Inhibins and activins are dimeric proteins of the transforming growth factor-beta superfamily which have been shown to be expressed in the adrenal cortex. Recent studies have suggested a role for these peptides in the pathogenesis and/or function of adrenal tumours. To investigate further their physiological and pathological roles, we have documented immunoreactivity for inhibin alpha, betaA and betaB subunits in normal adult and fetal human adrenals, in hyperplastic adrenals and in adrenal tumours. In the normal and hyperplastic adult gland, diffuse immunopositivity was demonstrated for beta subunits, suggesting that activins (beta beta dimers) can be expressed in all zones. Inhibin alpha was limited to the zona reticularis and the innermost zona fasciculata in the normal gland, extending centripetally into the zona fasciculata in hyperplasia, supporting a role for ACTH in the regulation of expression, and suggesting that expression of inhibins (alpha beta dimers) is restricted. Immunopositivity for all three subunits was seen in both fetal and definitive zones of the fetal cortex, indicating that both inhibins and activins could be expressed in both. Immunopositivity for all three subunits was seen in most adrenocortical tumours. Loss of immunopositivity for inhibin alpha in a subgroup of carcinomas might indicate a role in tumour progression. The greater intensity of staining for inhibin alpha in tumours associated with Cushing's syndrome again suggests a link with cortisol production. (+info)Influences of long-term administration of 24R, 25-dihydroxyvitamin D3, a vitamin D3 derivative, in rats. (7/1201)
In order to examine the influences by long-term feeding of 24R, 25 dihydroxyvitamin D3[24R, 25(OH)2D3], an active form of vitamin D, Wistar rats (14-week-old, male, 20 rats/group) were fed a powder diet containing 0 or 5 ppm 24R, 25(OH)2D3 for 57 weeks. Final body weights and total food consumption were comparable between the groups. Urinary calcium levels were significantly (p < 0.05 or 0.01) increased by the administration of 24R, 25(OH)2D3 at weeks 3, 22 and 56, although the levels of serum calcium did not differ between the groups at the termination of week 57. In the 24R, 25(OH)2D3 group, weights of the adrenals and femurs were significantly (p < 0.01) increased. Histopathologically, this was found due to thickening of cortical bone in the femurs, and medullary hyperplasia and pheochromocytoma of the adrenals. Immunohistochemically, proliferating cell nuclear antigen (PCNA)-labeling indices for intact adrenal medulla, medullary hyperplasia and pheochromocytoma in the 24R, 25(OH)2D3 group were respectively 1.82 +/- 1.21, 5.88 +/- 4.13 and 16, all higher than that for the adrenal medulla in the control group (0.87 +/- 0.67). These results indicate that 24R, 25(OH)2D3 at a dose with which serum calcium is not chronically increased causes thickening of the cortex of the femur, and development of adrenal proliferative lesions, suggesting that rats may be too sensitive for results to be relevant to human risk assessment. (+info)Calcium and reactive oxygen species as messengers in endotoxin action on adrenocortical cells. (8/1201)
The effect of Escherichia coli 0111:B4 endotoxin (lipopolysaccharide, LPS) on the intracellular Ca2+ and reactive oxygen metabolite content of both rat isolated fasciculata-reticularis and glomerulosa cells was evaluated by flow cytometry to know the role of these mechanisms in the initiation of cell injury produced by LPS on adrenocortical cells during endotoxic shock. A rapid increase of intracellular calcium was induced by endotoxin in both cell types. In fasciculata-reticularis cells, this [Ca2+]i increase was mainly due to an important mobilization of intracellular stores. Dose-dependent increases in [Ca2+]i were also observed when both cell types were incubated with LPS for 20 min in the presence of extracellular calcium. This treatment abolished the increase in intracellular calcium induced by ACTH and angiotensin II. On the other hand, the endotoxin produced a fast and dose-dependent increase in reactive oxygen species in both cell types, higher in glomerulosa than in fasciculata-reticularis cells. LPS-pretreated cells showed more susceptibility to the oxidative stress induced by Fe2+. These results can be related to functional alterations previously described showing the involvement of calcium and reactive oxygen species as messengers in the endotoxin action on adrenocortical cells.
