Retinoic acid stimulates the expression of 11beta-hydroxysteroid dehydrogenase type 2 in human choriocarcinoma JEG-3 cells. (1/232)

The syncytiotrophoblasts of the human placenta express high levels of 11beta-hydroxysteroid dehydrogenase type 2 (11beta-HSD2), the enzyme responsible for the inactivation of glucocorticoids. It has been proposed that the placental 11beta-HSD2 serves as a barrier to protect the fetus from high levels of maternal cortisol. To examine the hypothesis that nutritional signals regulate the expression of 11beta-HSD2 in placental syncytiotrophoblasts, we investigated the effects of retinoic acids (RAs), the major metabolites of vitamin A, on the expression of 11beta-HSD2 using human choriocarcinoma JEG-3 cells as a model. This trophoblast-like cell line displays a number of functional similarities to the syncytiotrophoblast. Treatment for 24 h with all-trans RA (1-1000 nM) resulted in a dose-dependent increase in 11beta-HSD2 activity with a maximal effect (increase to 3-fold) at 100 nM. The effect of all-trans RA (100 nM) was also time-dependent in that the effect was detectable at 6 h and reached its maximum by 48 h. Similar increases in 11beta-HSD2 activity were observed when the cells were treated with 9-cis RA. Results from semi-quantitative reverse transcription-polymerase chain reaction demonstrated that there was a corresponding increase in 11beta-HSD2 mRNA after RA treatment. Moreover, treatment with actinomycin D (100 ng/ml) abrogated the increase in 11beta-HSD2 mRNA induced by RA, indicating an effect on transcription. In conclusion, the present study has demonstrated for the first time that RA, at physiological concentrations, induces 11beta-HSD2 gene expression and enzyme activity in JEG-3 cells. If this occurs in vivo, the present finding suggests that high expression of 11beta-HSD2 in the human placenta may be maintained, at least in part, by dietary intake of vitamin A.  (+info)

Developmental expression of sodium entry pathways in rat nephron. (2/232)

During the past several years, sites of expression of ion transport proteins in tubules from adult kidneys have been described and correlated with functional properties. Less information is available concerning sites of expression during tubule morphogenesis, although such expression patterns may be crucial to renal development. In the current studies, patterns of renal axial differentiation were defined by mapping the expression of sodium transport pathways during nephrogenesis in the rat. Combined in situ hybridization and immunohistochemistry were used to localize the Na-Pi cotransporter type 2 (NaPi2), the bumetanide-sensitive Na-K-2Cl cotransporter (NKCC2), the thiazide-sensitive Na-Cl cotransporter (NCC), the Na/Ca exchanger (NaCa), the epithelial sodium channel (rENaC), and 11beta-hydroxysteroid dehydrogenase (11HSD). The onset of expression of these proteins began in post-S-shape stages. NKCC2 was initially expressed at the macula densa region and later extended into the nascent ascending limb of the loop of Henle (TAL), whereas differentiation of the proximal tubular part of the loop of Henle showed a comparatively retarded onset when probed for NaPi2. The NCC was initially found at the distal end of the nascent distal convoluted tubule (DCT) and later extended toward the junction with the TAL. After a period of changing proportions, subsegmentation of the DCT into a proximal part expressing NCC alone and a distal part expressing NCC together with NaCa was evident. Strong coexpression of rENaC and 11HSD was observed in early nascent connecting tubule (CNT) and collecting ducts and later also in the distal portion of the DCT. Ontogeny of the expression of NCC, NaCa, 11HSD, and rENaC in the late distal convolutions indicates a heterogenous origin of the CNT. These data present a detailed analysis of the relations between the anatomic differentiation of the developing renal tubule and the expression of tubular transport proteins.  (+info)

Inhibition of 11 beta-hydroxysteroid dehydrogenase obtained from guinea pig kidney by some bioflavonoids and triterpenoids. (3/232)

AIM: To study the inhibitory effect of some bioflavonoids and triterpenoids on 11 beta-hydroxysteroid dehydrogenase (11 beta-OHSD) from guinea pig kidney. METHOD: The 11 beta-OHSD of kidney cortex microsomes in addition of cortisol was incubated in the presence of NADP, Triton DF-18, and the test compounds at 37 degrees C for 1 h. The enzyme activity was assayed by measuring the rate of conversion of cortisol to cortisone eluted with HPLC gradient analysis. RESULTS: The IC50 (95% confidence limits) values of glycyrrhizic acid, naringenin, fisetin, emodin were 254 (202-320), 336 (270-418), 470 (392-564), and 527 (425-653) mumol.L-1, respectively. The inhibitory effect of oleanolic acid was 2-fold stronger than that of astramembranin I. The mode of action of naringenin was competitive inhibition. CONCLUSION: The test compounds inhibited the 11 beta-OHSD in kidney cortex with different potencies as glycyrrhizic acid did.  (+info)

Hypertension in mice lacking 11beta-hydroxysteroid dehydrogenase type 2. (4/232)

Deficiency of 11beta-hydroxysteroid dehydrogenase type 2 (11beta-HSD2) in humans leads to the syndrome of apparent mineralocorticoid excess (SAME), in which cortisol illicitly occupies mineralocorticoid receptors, causing sodium retention, hypokalemia, and hypertension. However, the disorder is usually incompletely corrected by suppression of cortisol, suggesting additional and irreversible changes, perhaps in the kidney. To examine this further, we produced mice with targeted disruption of the 11beta-HSD2 gene. Homozygous mutant mice (11beta-HSD2(-/-)) appear normal at birth, but approximately 50% show motor weakness and die within 48 hours. Both male and female survivors are fertile but exhibit hypokalemia, hypotonic polyuria, and apparent mineralocorticoid activity of corticosterone. Young adult 11beta-HSD2(-/-) mice are markedly hypertensive, with a mean arterial blood pressure of 146 +/- 2 mmHg, compared with 121 +/- 2 mmHg in wild-type controls and 114 +/- 4 mmHg in heterozygotes. The epithelium of the distal tubule of the nephron shows striking hypertrophy and hyperplasia. These histological changes do not readily reverse with mineralocorticoid receptor antagonism in adulthood. Thus, 11beta-HSD2(-/-) mice demonstrate the major features of SAME, providing a unique rodent model to study the molecular mechanisms of kidney resetting leading to hypertension.  (+info)

Glucocorticoids and insulin resistance: old hormones, new targets. (5/232)

Insulin resistance has been proposed as a mediator of the association between risk factors for cardiovascular disease in the population. The clinical syndrome of glucocorticoid excess (Cushing's syndrome) is associated with glucose intolerance, obesity and hypertension. By opposing the actions of insulin, glucocorticoids could contribute to insulin resistance and its association with other cardiovascular risk factors. In this review, we describe briefly the known mechanisms of insulin resistance and highlight the potential mechanisms for the effect of glucocorticoids. We then discuss factors which modulate the influence of glucocorticoids on insulin sensitivity; this highlights a novel therapeutic strategy to manipulate glucocorticoid action which may prove to be a useful tool in treating subjects with insulin resistance. Finally, we describe evidence from human studies that glucocorticoids make an important contribution to the pathophysiology of insulin resistance in the population.  (+info)

Targeting proteins to the lumen of endoplasmic reticulum using N-terminal domains of 11beta-hydroxysteroid dehydrogenase and the 50-kDa esterase. (6/232)

Previous studies identified two intrinsic endoplasmic reticulum (ER) proteins, 11beta-hydroxysteroid dehydrogenase, isozyme 1 (11beta-HSD) and the 50-kDa esterase (E3), sharing some amino acid sequence motifs in their N-terminal transmembrane (TM) domains. Both are type II membrane proteins with the C terminus projecting into the lumen of the ER. This finding implied that the N-terminal TM domains of 11beta-HSD and E3 may constitute a lumenal targeting signal (LTS). To investigate this hypothesis we created chimeric fusions using the putative targeting sequences and the reporter gene, Aequorea victoria green fluorescent protein. Transfected COS cells expressing LTS-green fluorescent protein chimeras were examined by fluorescent microscopy and electron microscopic immunogold labeling. The orientation of expressed chimeras was established by immunocytofluorescent staining of selectively permeabilized COS cells. In addition, protease protection assays of membranes in the presence and absence of detergents was used to confirm lumenal or the cytosolic orientation of the constructed chimeras. To investigate the general applicability of the proposed LTS, we fused the N terminus of E3 to the N terminus of the NADH-cytochrome b5 reductase lacking the myristoyl group and N-terminal 30-residue membrane anchor. The orientation of the cytochrome b5 reductase was reversed, from cytosolic to lumenal projection of the active domain. These observations establish that an amino acid sequence consisting of short basic or neutral residues at the N terminus, followed by a specific array of hydrophobic residues terminating with acidic residues, is sufficient for lumenal targeting of single-pass proteins that are structurally and functionally unrelated.  (+info)

NAD- and NADP-dependent 11 beta-hydroxysteroid dehydrogenase isoforms in guinea pig kidney with gossypol inhibition. (7/232)

AIM: To study the mechanism of gossypol-induced hypokalemia. METHODS: The 11 beta-hydroxysteroid dehydrogenase (11 beta-OHSD) protein was prepared from guinea pig kidney. The activity of 11 beta-OHSD with NAD or NADP as the coenzyme was measured by HPLC in both control and gossypol treatment. RESULTS: The Vmax and K(m) were 0.64 mmol.h-1/g protein and 0.07 mumol (cortisol) for NAD-dependent 11 beta-OHSD, 1.75 mmol.h-1/g protein and 0.21 mumol (cortisol) for NADP-dependent 11 beta-OHSD, respectively when 80 micrograms of enzyme protein was used. The inhibitory effects of gossypol on these two 11 beta-OHSD isoforms were different. The IC50 (95% confidence limits) were 50.2 (48.3-52.0) mumol of gossypol for NAD-dependent 11 beta-OHSD and 1143 (1098-1188) mumol of gossypol for NADP-dependent 11 beta-OHSD. The Ki was gossypol 96 mmol.L-1 for the former and 340 mmol.L-1 for the latter. CONCLUSION: The NAD-dependent 11 beta-OHSD is a more critical physiologic mechanism than NADP-dependent 11 beta-OHSD for hypokalemia caused by gossypol.  (+info)

Glucocorticoid resistance caused by reduced expression of the glucocorticoid receptor in cells from human vascular lesions. (8/232)

Mechanisms that control the balance between cell proliferation and death are important in the development of vascular lesions. Rat primary smooth muscle cells were 80% inhibited by low microgram doses of hydrocortisone (HC) and 50% inhibited by nanogram concentrations of transforming growth factor-beta1 (TGF-beta1), although some lines acquired resistance in late passage. However, comparable doses of HC, or TGF-beta1, failed to inhibit most human lesion-derived cell (LDC) lines. In sensitive LDC, HC (10 microg/mL) inhibited proliferation by up to 50%, with obvious apoptosis in some lines, and TGF-beta1 inhibited proliferation by more than 90%. Collagen production, as measured by [3H]proline incorporation or RIA for type III pro-collagen, was either unaffected or increased in the LDCs by HC. These divergent responses between LDC lines were partially explained by the absence of the glucocorticoid receptor (GR) and heat shock protein 90 mRNA in 10 of 12 LDC lines, but the presence of the mineralocorticoid receptor and 11beta-hydroxysteroid dehydrogenase type II. Western blot analysis confirmed the absence of the GR protein in cells lacking GR mRNA. Immunohistochemistry of human carotid lesions showed high levels of GR in the tunica media, but large areas lacking GR in the fibrous lesion. Considering the absence of the GR in most lines, the effects of HC may be elicited through the mineralocorticoid receptor. Functional resistance to the antiproliferative and antifibrotic effects of HC may contribute to excessive wound repair in atherosclerosis and restenosis.  (+info)

17 beta-hydroxysteroid dehydrogenases catalyze the oxidoreduction of hydroxy/oxo groups at position C17 of steroid hormones, thereby constituting a prereceptor control mechanism of hormone action. At present, 11 different mammalian 17 beta-hydroxysteroid dehydrogenases have been identified, catalyzing the cell- and steroid-specific activation and inactivation of estrogens and androgens. The human type 10 17 beta-hydroxysteroid dehydrogenase (17 beta-HSD-10) is a multifunctional mitochondrial enzyme that efficiently catalyzes the oxidative inactivation at C17 of androgens and estrogens. However, it also mediates oxidation of 3 alpha-hydroxy groups of androgens, thereby reactivating androgen metabolites. Finally, it is involved in beta-oxidation of fatty acids by catalyzing the L-hydroxyacyl CoA dehydrogenase reaction of the beta-oxidation cycle. These features and expression profiles suggest a critical role of 17 beta-HSD-10 in neurodegenerative and steroid-dependent cancer forms. Since no three
The biological activity of steroid hormones is regulated at the pre-receptor level by several enzymes including 17 beta-hydroxysteroid dehydrogenases (17 beta -HSD). The latter are present in many microorganisms, invertebrates and vertebrates. Dysfunctions in human 17 beta-hydroxysteroid dehydrogenases result in disorders of biology of reproduction and neuronal diseases, the enzymes are also involved in the pathogenesis of various cancers. 17 beta-hydroxysteroid dehydrogenases reveal a remarkable multifunctionality being able to modulate concentrations not only of steroids but as well of fatty and bile acids. Current knowledge on genetics, biochemistry and medical implications is presented in this review.
Clinical observations have highlighted the link between glucocorticoids and obesity. While exogenous glucocorticoids in excess predispose to the development of central obesity, we have focused on cortisol metabolism within human adipose tissue. 11beta-hydroxysteroid dehydrogenase (11beta-HSD) inter-converts the active glucocorticoid, cortisol, and inactive cortisone. 11beta-HSD1, the only isoform expressed in adipose tissue, acts predominantly as an oxoreductase to generate cortisol. Expression is higher in omental compared to subcutaneous preadipocytes and activity and expression are potently regulated by growth factors and cytokines. Mice over-expressing 11beta-HSD1 specifically within adipocytes develop central obesity. However, the situation is less clear in humans. Globally, there appears to be inhibition of the enzyme, but expression in human obesity is still not fully characterized; its functional role in adipocyte biology remains to be elucidated. In vitro, 11beta-HSD1 appears to function in

17Beta-hydroxysteroid dehydrogenases (17beta-HSDs) catalyze the NAD(P)(H) dependent oxidoreduction at C17 oxo/beta-hydroxyl groups of androgen and estrogen hormones. This reversible reaction constitutes an important pre-receptor control mechanism for nuclear receptor ligands, since the conversion switches between the 17beta-OH receptor ligands and their inactive 17-oxo metabolites. At present, 14 mammalian 17beta-HSDs are described, of which at least 11 exist within the human genome, encoded by different genes. The enzymes differ in their expression pattern, nucleotide cofactor preference, steroid substrate specificity and subcellular localization, and thus constitute a complex system ensuring cell-specific adaptation and regulation of sex steroid hormone levels. Broad and overlapping substrate specificities with enzymes involved in lipid metabolism suggest interactions of several 17beta-HSDs with other metabolic pathways. Several 17beta-HSDs enzymes constitute promising drug targets, of particular

11 beta-Hydroxysteroid dehydrogenase (11 beta-HSD) catalyzes the conversion of the glucocorticoid corticosterone (cortisol in humans) to inert 11-dehydrocorticosterone (cortisone). 11 beta-HSD activity is present in the hippocampus, where it is induced by glucocorticoids and stress in vivo, prompting suggestions that the enzyme may attenuate the deleterious effects of chronic glucocorticoid excess on neuronal function and survival. Two isoforms exist: 11 beta-HSD1, a bidirectional NADPH-dependent enzyme, and 11 beta-HSD2, an NAD(+)- dependent exclusive 11 beta-dehydrogenase (corticosterone-inactivating enzyme). In this study, 11 beta-HSD1 activity and mRNA synthesis were demonstrated in primary fetal hippocampal cell cultures. Unexpectedly, the reaction direction in intact hippocampal cells was 11 beta- reduction (reactivation of inert 11-dehydrocorticosterone), although homogenization revealed that the enzyme was capable of 11 beta- dehydrogenation when removed from its normal cellular context. ...

Carbonyl reduction is a significant step in the biotransformation leading to the elimination, of endogenous and exogenous aldehydes, ketones and quinones. This reaction is mediated by members of the aldo-keto reductase and short-chain dehydrogenase/reductase (SDR) superfamilies. The essential role of these enzymes in protecting organisms from damage by the accumulation of toxic carbonyl compounds is generally accepted, although their physiological roles are not always clear. Recently, the SDR enzyme 11beta-hydroxysteroid dehydrogenase-1 has been identified to perform an important role in the detoxification of non-steroidal carbonyl compounds, in addition to metabolising its physiological glucocorticoid substrates. This review summarises the current knowledge of type-1 11beta-hydroxysteroid dehydrogenase and discusses possible substrate/inhibitor interactions.

The enzyme 3beta/17beta-hydroxysteroid dehydrogenase (3beta/17beta-HSD) is a steroid-inducible component of the Gram-negative bacterium Conramonas testosteroni. It catalyzes the reversible reduction/ dehydrogenation of the oxo/beta-hydroxy groups at positions 3 and 17 of steroid compounds, including hormones and isobile acids. Crystallographic analysis at 1.2 Angstrom resolution reveals the enzyme to have nearly identical subunits that form a tetramer with 222 symmetry. This is one of the largest oligomeric structures refined at this resolution. The subunit consists of a monomer with a single-domain structure built around a seven-stranded beta-sheet flanked by six alpha-helices. The active site contains a Ser-Tyr-Lys triad, typical for short-chain dehydrogenases/reductases (SDR). Despite their highly diverse substrate specificities, SDR members show a close to identical folding pattern architectures and a common catalytic mechanism. In contrast to other SDR apostructures determined, the ...
Mutagenetic replacements of conserved residues within the active site of the short-chain dehydrogenase/reductase (SDR) superfamily were studied using prokaryotic 3 beta/17 beta-hydroxysteroid dehydrogenase (3 beta/17 beta-HSD) from Comamonas testosteroni as a model system. The results provide novel data to establish Ser 138 as a member of a catalytically important triad of residues also involving Tyr151 and Lys155. A Ser--|Ala exchange at position 138 results in an almost complete (| 99.9%) loss of enzymatic activity, which is not observed with a Ser--|Thr replacement. This indicates that an essential factor for catalysis is the ability of side chain 138 to form hydrogen bond interactions. Mutations in the NAD(H) binding region, in strands beta A, beta D, and adjacent turns, reveal two additional residues, Thr12 and Asn87, which are important for correct binding of the coenzyme and with a differential effect on the reactions catalyzed. Thus, mutation of Thr12 to Ala results in a complete loss of the 3

TY - JOUR. T1 - 11 beta-hydroxysteroid dehydrogenase type 2 in mouse aorta - Localization and influence on response to glucocorticoids. AU - Christy, C AU - Hadoke, P W F AU - Paterson, J M AU - Mullins, J J AU - Seckl, J R AU - Walker, B R PY - 2003/10. Y1 - 2003/10. N2 - Both isozymes of 11 beta-hydroxysteroid dehydrogenase, which interconvert active and inactive glucocorticoids, are expressed in the mouse aortic wall. Mice deficient in 11HSD type 2 ( which converts active corticosterone into inert 11-dehydrocorticosterone) have hypertension and impaired endothelial nitric oxide activity. It has been suggested that 11HSD2 influences vascular function directly by limiting glucocorticoid-mediated inhibition of endothelium-derived nitric oxide. This study sought to determine (1) the cellular distribution of the 11HSD isozymes within the mouse aortic wall and (2) the influence of 11HSD2 on direct glucocorticoid-mediated changes in aortic function. Mouse aortas were separated into their component ...
Girls with idiopathic premature adrenarche, characterized by the early appearance of pubic hair and adrenal hyperandrogenism, may be at an increased risk for polycystic ovarian syndrome and its associated complications. Alterations of peripheral metabolism of adrenal steroids, specifically increased 5 alpha-reductase and 11 beta-hydroxysteroid dehydrogenase activities, have been documented in patients with polycystic ovarian syndrome and proposed as an underlying mechanism for the adrenal hyperandrogenism in this syndrome. We sought to investigate whether alterations in 5 alpha-reductase and 11 beta-hydroxysteroid dehydrogenase activities are present in girls with premature adrenarche, suggesting a possible role in the pathogenesis of the hyperandrogenism of this condition. We studied C19 and C21 urinary steroid metabolites, 5 alpha/5 beta and 11 oxo/11 hydroxy metabolite pairs as well as the ratios of the total 5 alpha/total 5 beta and total 11 oxo/total 11 hydroxy metabolites in 24-h urine samples
The global epidemic of obesity has heightened the need to understand the mechanisms that underpin its pathogenesis. Clinical observations in patients with Cushings syndrome have highlighted the link between cortisol and central obesity. However, although circulating cortisol levels are normal or reduced in obesity, local regeneration of cortisol, from inactive cortisone, by 11beta-hydroxysteroid dehydrogenase type 1 (11betaHSD1) has been postulated as a pathogenic mechanism. Although levels of expression of 11betaHSD1 in adipose tissue in human obesity are debated in the literature, global inhibition of 11betaHSD1 improves insulin sensitivity. We have determined the effects of significant weight loss on cortisol metabolism and adipose tissue 11betaHSD1 expression after 10-wk ingestion of a very low calorie diet in 12 obese patients (six men and six women; body mass index, 35.9 +/- 0.9 kg/m2; mean +/- SE). All patients achieved significant weight loss (14.1 +/- 1.3% of initial body weight). Total fat

Inherited adrenal and gonadal 3 beta-hydroxysteroid dehydrogenase (3 beta-HSD) deficiency is most likely caused by a mutation of the type II 3 beta-HSD gene. Cloning and sequencing of exons I-II, III, and IV and portions of the adjacent introns, amplified by polymerase chain reaction using primers specific for the type II gene, in one male pseudohermaphrodite with salt-wasting classic 3 beta-HSD deficiency congenital adrenal hyperplasia revealed the same mutation in all nine clones of exon IV consisting of a missense mutation at codon 248 [GTC(Val)--,AAC(Asn)] followed by a frameshift mutation at codon 249 [CGA (Arg)--,TA], resulting in a stop codon TAG, and normal sequences of exon I-II and III and the adjacent portions of introns ...
Pre-eclampsia leads to disturbed fetal organ development, including metabolic syndrome, attributed to altered pituitary-adrenal feedback loop. We measured cortisol metabolites in infants born from pre-eclamptic and normotensive women and hypothesised that glucocorticoid exposure would be exaggerated in the former. Twenty-four hour urine was collected from infants at months 3 and 12. Cortisol metabolites and apparent enzyme activities were analysed by gas chromatography-mass spectrometry. From 3 to 12 months, excretion of THS, THF and pregnandiol had risen in both groups; THF also rose in the pre-eclamptic group. No difference was observed with respect to timing of the visit or to hypertensive status for THE or total F metabolites (P,0.05). All apparent enzymes activities, except 17α-hydroxylase, were lower in infants at 12 compared to 3 months in the normotensive group. In the pre-eclamptic group, only 11β-HSD activities were lower at 12 months.17α-hydroxylase and 11β-HSD activities of ...

The anthracycline doxorubicin (DOX) is an exceptionally good antineoplastic agent, but its use is limited by formation of metabolites which induce acute and chronic cardiac toxicities. Whereas the acute toxicity is mild, the chronic toxicity can produce a life-threatening cardiomyopathy. Studies in laboratory animals are of limited value in predicting the structure and reactivity of toxic metabolites in humans; therefore, we used an ethically acceptable system which is suitable for exploring DOX metabolism in human myocardium. The system involves cytosolic fractions from myocardial samples obtained during aorto-coronary bypass grafting. After reconstitution with NADPH and DOX, these fractions generate the alcohol metabolite doxorubicinol (DOXol) as well as DOX deoxyaglycone and DOXol hydroxyaglycone, reflecting reduction of the side chain carbonyl group, reductase-type deglycosidation of the anthracycline, and hydrolase-type deglycosidation followed by carbonyl reduction, respectively.

The concurrent administration of compound E at a daily dosage of 2 mg. per kg. to rabbits receiving daily intracutaneous injections of crystalline egg albumin markedly inhibited the development of anaphylactic hypersensitivity of the Arthus type. ACTH, when given at a similar dosage, produced a much less marked effect. Both hormones suppressed circulating antibody and as with the Arthus reaction, the suppression produced by compound E was much greater than that obtained with ACTH.. When treatment with compound E was started following sensitization, there was a rapid decline in circulating antibody and, if the pretreatment serum antibody was low, there was also a progressive decrease in skin reactivity, becoming negative after 5 days of treatment. When the pretreatment serum antibody concentration was great, so that by the termination of treatment the antibody concentration was still above the level ordinarily sufficient for a maximal skin response, the Arthus reaction was unaffected by ...

Adenosine is a nucleoside that is composed of adenine and d-ribose. Adenosine or adenosine derivatives play many important biological roles in addition to being components of DNA and RNA. For instance, adenosine plays an important role in energy transfer - as adenosine triphosphate (ATP) and adenosine diphosphate (ADP). It also plays a role in signal transduction as cyclic adenosine monophosphate, cAMP. Adenosine itself is both a neurotransmitter and potent vasodilator. When administered intravenously, adenosine causes transient heart block in the AV node. Because of the effects of adenosine on AV node-dependent supraventricular tachycardia, adenosine is considered a class V antiarrhythmic agent ...

Mutations in HSD3B2, the gene for 3beta-hydroxysteroid dehydrogenase type II (3beta-HSD II) have been detected and activities analysed through the in vitro expression of mutant cDNAs. Two full sibs with male pseudohermaphroditism were found to be double heterozygotes: N100S/266DeltaA. This genotype leads to the most profound loss of 3beta-HSD II enzyme activity (1.3% of normal) described to date in cases without severe salt-loss. One sib (N100S/266DeltaA) is the first reported male case of type II deficiency affected with premature adrenarche. Three apparently independent kindreds had propositi affected with the HSD3B2 mutation A82T/A82T, which is associated with a non salt-losing phenotype with variable expressivity in females. These three families had the same extended HSD3B haplotype and are likely to have inherited the same ancestral mutation. The significance of this finding is discussed in the light of the presence of A82T mutation at a homologous position in pseudogene varphi5 that is ...

INTRODUCTION: CYP3A is responsible for the metabolism of numerous endogenous and exogenous compounds. Several substrates of CYP3A have been investigated to assess the CYP3A-metabolizing capacity of an individual in an attempt to predict the rate of metabolism of other CYP3A substrates. Two such tests of CYP3A activity are the midazolam plasma clearance after its intravenous administration and the 6beta-OH cortisol urinary ratio. Possible correlations between these 2 tests were investigated before and after treatment with rifampin in a group of healthy volunteers. METHODS: Pharmacokinetic parameters of midazolam and 6beta-OH cortisol urinary ratio were evaluated in 8 volunteers before and after 6 days treatment with rifampin, a potent inducer of CYP3A, and after cessation of rifampin treatment. RESULTS: Midazolam systemic clearance and the 6beta-OH cortisol urinary ratio were significantly higher at Days 7 and 10 than at Day 0. There was a strong positive correlation between these 2 parameters (r ...

Human 17beta-hydroxysteroid dehydrogenase type 1 (17β-HSD1) is a steroid-converting enzyme that has long been known to play critical roles in estradiol synthesis and more recently in dihydrotestosterone (DHT) inactivation, showing a dual function that promotes breast cancer cell proliferation. Previously, we reported the first observation of the influence of the enzyme on endogenous estrogen-responsive gene expression. Here, we demonstrate the impact of 17β-HSD1 expression on the breast cancer cell proteome and investigate its role in cell migration. 17β-HSD1 was stably transfected in MCF7 cells and the proteome of the generated cells overexpressing 17β-HSD1 (MCF7-17βHSD1 cells) was compared to that of the wild type MCF7 cells. Proteomics study was performed using two-dimensional gel electrophoresis followed by mass spectrometry analysis of differentially expressed protein spots. Reverse transcription quantitative real-time PCR (RT-qPCR) was used to investigate the transcription of individual gene.

Vertebrates release glucocorticoids during stressful events. If stress occurs during reproduction, the resulting offspring can show altered phenotypes that are thought to arise from increased exposure to maternal glucocorticoids. Developing offspring can metabolize maternal glucocorticoids, which can alter the pattern of exposure they encounter. For egg laying vertebrates, we are just beginning to understand how embryonic steroid metabolism impacts embryonic exposure to maternal glucocorticoids. Here we injected three doses of radioactive corticosterone into Japanese quail (Coturnix japonica) eggs to determine the degree of embryonic exposure at days six and nine of development. We found that increasing injection dose increased the amount of radioactivity found in the embryo at day six but by day nine the effect of injection dose disappeared as the amount of radioactivity within the embryo dropped to equivalent levels for all three doses. Interestingly, when examined as a percentage of initial dose,
This gene encodes a member of the 17beta-hydroxysteroid dehydrogenase family of short-chain dehydrogenases/reductases. It has a dual function in estrogen activation and androgen inactivation and plays a major role in establishing the estrogen E2 concentration gradient between serum and peripheral tissues. The encoded protein catalyzes the last step in estrogen activation, using NADPH to convert estrogens E1 and E2 and androgens like 4-androstenedione, to testosterone. It has an N-terminal short-chain dehydrogenase domain with a cofactor binding site, and a narrow, hydrophobic C-terminal domain with a steroid substrate binding site. This gene is expressed primarily in the placenta and ovarian granulosa cells, and to a lesser extent, in the endometrium, adipose tissue, and prostate. Polymorphisms in this gene have been linked to breast and prostate cancer. A pseudogene of this gene has been identified. Alternative splicing results in multiple transcript variants.

17beta-hydroxysteroid dehydrogenase type12 (HSD17B12) has been demonstrated to be involved in regulation of in situ biosynthesis of estradiol (E2). HSD17B12 expression was reported in breast carcinomas but its functions have remained unknown. Therefore, we examined the correlation between mRNA expression profiles determined by microarray analysis and tissue E2 concentrations obtained from 16 postmenopausal breast carcinoma cases in order to analyze an association of the enzyme expression with intratumoral E2 production. No significant correlations were detected between intratumoral HSD17B12expression and E2 concentration.These findings suggest that the presence of HSD17B12 in carcinoma cells contributes to a development of human breast carcinoma via a pathway other than in situ E2 biosynthesis.
The relationship between stress, cortisol and an increase in body fat has been well established. However, new research has identified a little known enzyme deep within fat cells called 11 beta-hydroxysteroid dehydrogenase-1 or HSD. The HSD enzyme converts the inactive form of cortisol (called cortisone) into the active, fat storing form called cortisol.. Researchers in Germany noted that the rate of activity of the HSD enzyme determines the rate of fat storage in the individual. When individuals were experiencing high levels of HSD activity, no amount of exercise, diet or stress management are able to prevent fat gain.. The activity of the HSD enzyme increases with age. Women and men in their thirties and forties can experience as much a 300% increase in HSD activity compared to an individual in their twenties. This may account to for steady increase in stubborn body fat observed in individuals as they age.. ...
According to the current analysis of Reports and Data, the global Cortisone market was valued at USD 1.15 billion in 2018 and is expected to reach USD 1.54 billion by year 2026, at a CAGR of 3.7%. The study covers drivers impacting the market growth, obstruction of the market and upcoming opportunities of the cortisone market. Cortisone is a naturally occurring glucocorticoid that reduces the body immune response. Cortisone is an inactive agent itself but get converted into an active metabolite hydrocortisone into liver. The glucocorticoid (cortisone) work through the glucocorticoid receptors, inhibiting molecules responsible for inflammation.

Progestogel action mechanism is based on increasing concentrations of progesterone in the tissues of the breast. Progesterone reduces the expression of estrogen receptors in breast tissue and also reduces the local level of active estrogens by stimulating the production of enzymes (17-beta-hydroxysteroid dehydrogenase and estronsulfotransferazy) oxidizing estradiol less active estrone (linking the latter, enzymes convert it into an inactive estrone sulfate). ...
