Mechanism of Action Prostate cancer is known to be androgen sensitive and responds to androgen ablation. In animal studies, nilutamide has demonstrated antiandrogenic activity without other hormonal (estrogen, progesterone, mineralocorticoid, and glucocorticoid) effects. In vitro, nilutamide blocks the effects of testosterone at the androgen receptor level. In vivo, nilutamide interacts with the androgen receptor and prevents the normal androgenic response.. Pharmacokinetics Absorption Analysis of blood, urine, and feces samples following a single oral 150-mg dose of [14C]-nilutamide in patients with metastatic prostate cancer showed that the drug is rapidly and completely absorbed and that it yields high and persistent plasma concentrations.. Distribution After absorption of the drug, there is a detectable distribution phase. There is moderate binding of the drug to plasma proteins and low binding to erythrocytes. The binding is nonsaturable except in the case of alpha-1-glycoprotein, which ...

TY - JOUR. T1 - Dose-dependent prevention of sugar cataracts in galactose-fed dogs by the aldose reductase inhibitor M79175. AU - Sato, Sanai. AU - Mori, Kazuhiko. AU - Wyman, Milton. AU - Kador, Peter F.. PY - 1998/2. Y1 - 1998/2. N2 - Sugar cataracts rapidly develop in dogs fed a diet containing 30% galactose. While studies on the formation and progression of these sugar cataracts suggest that they are osmotic in nature and are linked to aldose reductase, sugar cataract formation in the dog to date has not been completely prevented by the administration of aldose reductase inhibitors sorbinil and M79175. To demonstrate that the formation and progression of sugar cataracts in galactose-fed dogs can be dose-dependently inhibited by the administration of aldose reductase inhibitors, 9-month old male beagles were placed on diet containing 30% galactose with/without 10 or 16 mg kg-1 day-1 of M79175 for up to 39 months. Cataract progression in all dogs was followed by periodic slit lamp examination ...

Prostacyclin (PGI 2 ) is a major product of COX-2 catalyzed metabolism of arachidonic acid in the endothelium and has been shown to be atheroprotective. PGI 2 signals though its G-coupled protein receptor (GPCR) the human Prostacyclin receptor (hIP) leading to the downstream production of cAMP thereby mediating a number of cellular pathways. The prostacyclin receptor knockout mice exhibit increased atherosclerosis, enhanced thrombosis, and enhanced proliferative response to carotid vascular injury with increased intima to media ratios 1-3. Single nucleotide polymorphisms (SNPs) constitute greater than 80% of our genetic diversity and are known to play a role in the pathogenesis of disease and individual response to medical therapy. This thesis sets forth to: (1) determine the clinical significance of certain SNPs in the hIP gene and their association with cardiovascular disease (CVD), (2) Determine the relationship between hIP expression in human platelets with CVD severity, and (3) elucidate ...

TY - JOUR. T1 - A stable prostacyclin analog, beraprost sodium, attenuates platelet accumulation and preservation-reperfusion injury of isografts in a rat model of lung transplantation. AU - Okada, Yoshinori. AU - Marchevsky, Alberto M.. AU - Kass, Robert M.. AU - Matloff, Jack M.. AU - Jordan, Stanley C.. PY - 1998/11/15. Y1 - 1998/11/15. N2 - Background. Recent studies have shown that the extent of platelet accumulation in the vasculature of transplanted organs correlates with the degree of preservation-reperfusion injury. In this study, we examined the effect of a stable prostacyclin analog, beraprost sodium, which possesses potent antiplatelet activity, on parameters of platelet accumulation and preservation-reperfusion injury of isografts in a rat model of lung transplantation. Methods. The heart-lung blocks of donor rats were flushed with and preserved in modified Euro-Collins solution at 4°C for 6 hr or 24 hr. The left lung was transplanted into recipient rats and reperfused for 1 hr. ...

In the human erythroleukemia cell line, HEL, prostaglandin E2 (PGE2) and the stable prostacyclin analogue, iloprost, increase cytosolic Ca2+ concentration ([Ca2+]i) via pertussis toxin-sensitive and -insensitive pathways. Unlike iloprost, the stable prostacyclin analogue cicaprost (ZK 96480), is devoid of agonistic properties at prostaglandin E2 receptors. We compared the effects of cicaprost, iloprost and PGE2 on [Ca2+]i in HEL cells. Cicaprost, iloprost and PGE2 were similarly potent to increase [Ca2+]i in HEL cells. However, unlike the effects of PGE2, those of the prostacyclin analogues were not inhibited by pertussis toxin. The prostaglandins studied increased [Ca2+]i through both mobilization from internal stores and Ca2+ influx from the extracellular space. Prostacyclin analogue- and PGE2-induced rises in [Ca2+]i were desensitized in a homologous manner. Additionally, there was cross-desensitization between cicaprost and iloprost, but not between the prostacyclin analogues and PGE2. Our ...

Imidazole derivatives have attracted significant interests in recent time for their usefulness in synthetic heterocyclic chemistry, analytical chemistry and pharmacology. Aim of present study was to evaluate the impact of biofield treatment on two imidazole derivatives (i.e., imidazole and 2-methylimidazole) by various analytical methods. The biofield treatment was done by Mr. Trivedi on both the compounds and both control and treated samples of imidazole and 2-methylimidazole were characterized with respect to physical, and structural properties using X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Fourier transform infrared (FTIR), ultraviolet-visible (UV-Vis) spectroscopy, and Gas chromatography-Mass spectrometry (GC-MS). X-ray diffraction study revealed that crystallite size varied in a different way for imidazole and 2-methylimidazole due to the presence of methyl group in 2-c position although their core was same. Treated sample of ...

TY - JOUR. T1 - Aldose reductase inhibition by ponalrestat (statil) does not prevent proteinuria in long-term diabetic rats. AU - Reddi, A. S.. AU - Jyothirmayi, G. N.. PY - 1993/1/1. Y1 - 1993/1/1. N2 - The aldose reductase pathway has been implicated in the development of chronic complications of diabetes. In this study, we investigated the effect of an aldose reductase inhibitor, statil, on glomerular synthesis of heparan sulfate and albuminuria in male Wistar rats made diabetic with streptozotocin. Heparan sulfate is the predominant glycosaminoglycan (GAG) proteoglycan in the glomerular basement membrane (GBM). It confers a negative charge on the GBM, and its loss has been related to the presence of albumin in the urine. Diabetic rats synthesized less glomerular heparan sulfate and excreted more albumin than normal rats. Glomerular sorbitol concentration was significantly higher in diabetic than in normal rats. Chronic treatment of diabetic rats with statil did not improve either heparan ...

TY - JOUR. T1 - Progression of sugar cataract in the dog.. AU - Sato, S.. AU - Takahashi, Y.. AU - Wyman, M.. AU - Kador, P. F.. PY - 1991/5. Y1 - 1991/5. N2 - Young beagle dogs were fed a 30% galactose diet, with or without the aldose reductase inhibitors sorbinil or M79175. Cataract formation was monitored by indirect ophthalmoscope and hand-held slit-lamp microscopy and documented by retroillumination photography. In these dogs, the first sign of cataract development was an accentuation of the anterior and posterior lens sutures (1 month after feeding), then the appearance of cortical vacuoles (3 months after feeding), and finally, the formation of predominantly equatorial cortical opacities toward the posterior cortices (4-6 months after feeding). After long-term galactose feeding, a progressive, irregular, clear zone formed at the cortical equatorial regions. Light microscopic examination of these lenses shows that the cataracts are osmotic, many of the lens fibers appear to be swollen or ...

Dogs were assigned to 3 groups (control group, low dose [10 μg of zoledronic acid/kg], or high dose [25 μg of zoledronic acid/kg). Treatments were administered SC every 3 months for 1 year beginning the day after CrCL transection. Serum and synovial fluid samples and radiographs were obtained 0, 1, ...

Olmesartan medoxomil. Olmesartan was not carcinogenic when administered by dietary administration to rats for up to 2 years. The highest dose tested (2000 mg/kg/day) was, on a mg/m 2 basis, about 480 times the maximum recommended human dose (MRHD) of 40 mg/day. Two carcinogenicity studies conducted in mice, a 6-month gavage study in the p53 knockout mouse and a 6-month dietary administration study in the Hras2 transgenic mouse, at doses of up to 1000 mg/kg/day (about 120 times the MRHD), revealed no evidence of a carcinogenic effect of olmesartan. Both olmesartan medoxomil and olmesartan tested negative in the in vitro Syrian hamster embryo cell transformation assay and showed no evidence of genetic toxicity in the Ames (bacterial mutagenicity) test. However, both were shown to induce chromosomal aberrations in cultured cells in vitro (Chinese hamster lung) and tested positive for thymidine kinase mutations in the in vitro mouse lymphoma assay. Olmesartan medoxomil tested negative in vivo for ...

Prostate cancer is the most commonly diagnosed non-cutaneous malignancy of men in the United States and remains the second leading cause of cancer-related mortality among men. Novel approaches are necessary to personalize and improve treatment. The androgen receptor (AR) plays a critical role in the normal development and function of the prostate and promotes growth in most prostate cancers. Most patients with advanced prostate cancer have cancer that will initially respond to androgen-targeting therapy (focusing on decreasing the circulating levels of testosterone which is the primary source of ligand for the AR receptor). However, castrate resistance usually develops within 18 to 24 months and the median survival of men with castration resistant prostate cancer (CRPC) ranges between 12 to 18 months. Current options are limited including: secondary hormonal manipulations, radiopharmaceuticals, and chemotherapy and only docetaxel, a taxane that targets microtubules, has been proven to prolong ...

A class of insecticides that has been linked to Bee Colony Collapse Disorder of honey bees MAY NOT BE AS MUCH OF A CULPRIT AS THOUGHT.. Neonicotinoid Insecticides, sometimes called Neonics, are neuro-active insecticides chemically similar to nicotine.. One of them, imidacloprid, is the most widely used insecticide in the world.. Compared to organophosphates and carbamates, Neonicotinoid Insecticides CAUSE LESS TOXICITY IN BIRDS AND MAMMALS AND INSECTS.. While Neonicotinoid Insecticides can harm honey bees, a new study by Washington State University ( WSU ) researchers shows Neonicotinoid Insecticides POSE LITTLE RISK TO BEES IN REAL-WORLD SETTINGS..

BACKGROUND: In a phase 2 trial, selexipag, an oral selective IP prostacyclin-receptor agonist, was shown to be beneficial in the treatment of pulmonary arterial hypertension.. METHODS: In this event-driven, phase 3, randomized, double-blind, placebo-controlled trial, we randomly assigned 1156 patients with pulmonary arterial hypertension to receive placebo or selexipag in individualized doses (maximum dose, 1600 μg twice daily). Patients were eligible for enrollment if they were not receiving treatment for pulmonary arterial hypertension or if they were receiving a stable dose of an endothelin-receptor antagonist, a phosphodiesterase type 5 inhibitor, or both. The primary end point was a composite of death from any cause or a complication related to pulmonary arterial hypertension up to the end of the treatment period (defined for each patient as 7 days after the date of the last intake of selexipag or placebo).. RESULTS: A primary end-point event occurred in 397 patients--41.6% of those in the ...

Background: Zoledronic acid is very widely used in patients with metastatic bone disease and osteoporosis. Only one case of bilateral uveitis was recently reported related to its use. Case presentation: We report the first case of severe unilateral anterior uveitis in a patient with breast cancer and an intraocular lens. Following zoledronic acid infusion, the patient developed severe and dramatic right eye pain with decreased visual acuity within 24 hours and was found to have a fibrinous anterior uveitis of moderate severity. The patient was treated with topical prednisone and atropine eyedrops and recovered slowly over several months. Conclusions: Internists, oncologists, endocrinologists, and ophtalmologists should be aware of uveitis as a possible complication of zoledronic acid therapy. Patients should be instructed to report immediately to their physicians and treatment with topical prednisone and atropine eyedrops should be instituted immediately at the onset of symptoms. This report ...

Aryl-alcohol oxidase (AAO, EC 1.1.3.7) generates H2O2 for lignin degradation at the expense of benzylic and other π system-containing primary alcohols, which are oxidized to the corresponding aldehydes. Ligand diffusion studies on Pleurotus eryngii AAO showed a T-shaped stacking interaction between the Tyr92 side chain and the alcohol substrate at the catalytically competent position for concerted hydride and proton transfers. Bi-substrate kinetics analysis revealed that reactions with 3-chloro- or 3-fluorobenzyl alcohols (halogen substituents) proceed via a ping-pong mechanism. However, mono- and dimethoxylated substituents (in 4-methoxybenzyl and 3,4-dimethoxybenzyl alcohols) altered the mechanism and a ternary complex was formed. Electron-withdrawing substituents resulted in lower quantum mechanics stacking energies between aldehyde and the tyrosine side chain, contributing to product release, in agreement with the ping-pong mechanism observed in 3-chloro- and 3-fluorobenzyl alcohol kinetics ...

Transient global cerebral ischemia causes delayed neuronal death in the hippocampal CA1 region. It also induces an up regulation of cyclooxygenase 2 (COX-2), which generates several metabolites of arachidonic acid, known as prostanoids, including Prostaglandin I2 (PGI2). The present study investigated whether the PGI2 IP receptor plays an important role in brain injury after global cerebral ischemia in aged mice. Adult young (2-3 months) and aged (12-15 months) male C57Bl/6 wild-type (WT) or IP receptor knockout (IP KO) mice underwent a 12 min bilateral common carotid artery occlusion (BCCAO) or a sham surgery. Behavior tests (neurologic deficit and T-maze) were performed 3 and 7 days after BCCAO. After seven days of reperfusion, the numbers of cells positive for markers of neurons, astrocytes, microglia, myeloperoxidase (MPO) and phosphorylated CREB (p-CREB) were evaluated immunohistochemically. Interestingly, in young and aged IP KO ischemic mice, there was a significant increase (p < 0.01) in

Changes in Gibbs energy, entropy and van't Hoff enthalpy were additionally calculated.. AB - The inclusion ...

Prostaglandin receptors or prostanoid receptors represent a sub-class of cell surface membrane receptors that are regarded as the primary receptors for one or more of the classical, naturally occurring prostanoids viz., prostaglandin D2, (i.e. PGD2), PGE2, PGF2alpha, prostacyclin (PGI2), thromboxane A2 (TXA2), and PGH2.[1] They are named based on the prostanoid to which they preferentially bind and respond, e.g. the receptor responsive to PGI2 at lower concentrations than any other prostanoid is named the Prostacyclin receptor (IP). One exception to this rule is the receptor for thromboxane A2 (TP) which binds and responds to PGH2 and TXA2 equally well. All of the prostanoid receptors are G protein-coupled receptors belonging to the Subfamily A14 of the rhodopsin-like receptor family except for the Prostaglandin DP2 receptor which is more closely related in amino acid sequence and functionality to chemotactic factor receptors such as the receptors for C5a and leukotriene B4.[2] Prostanoid ...

Alcohol intolerance is due to a genetic polymorphism of the enzyme alcohol dehydrogenase, the enzyme that metabolises ingested alcohol. This polymorphism is most often reported in Asian patients.[1] It can also be an effect or side effect associated with certain drugs such as disulfiram, metronidazole, or nilutamide. Stuffy nose and skin flushing are the most common symptoms when ingesting alcohol.[2] It may also be characterized as intolerance causing hangover symptoms similar to the "disulfiram-like reaction" of aldehyde dehydrogenase deficiency or chronic fatigue syndrome. Severe pain after drinking alcohol may indicate a more serious condition.[3] If people are intolerant, some nearly non-alcoholic beverages may be a problem, similar to alcohol-containing medications, vinegar, inhalation of alcohol or the vapour of alcohol-containing cleaning agents. Drinking alcohol first or afterwards together with Calcium cyanamide, an inorganic compound used as a fertilizer, can cause permanent or long ...

Low apparent aldose reductase activity, as measured by NADPH oxidation, can be produced by the spontaneous autoxidation of monosaccharides. NADPH is oxidized to metabolically active NADP+ in a solution of autoxidizing DL-glyceraldehyde at rates of up to 15 X 10(-4) A340/min. The close parallelism between the effects of buffer salt type and concentration, monosaccharide structure and temperature activation on autoxidation and NADPH oxidation imply that autoxidation is a prerequisite for the NADPH oxidation, probably via the hydroperoxy radical. Nucleotide-binding proteins enhanced NADPH oxidation induced by DL-glyceraldehyde, up to 10.6-fold with glucose-6-phosphate dehydrogenase. Glutathione reductase-catalysed NADPH oxidation in the presence of autoxidizing monosaccharide showed many characteristics of the aldose reductase reaction. Aldose reductase inhibitors acted as antioxidants in inhibiting this NADPH oxidation. These results indicate that low apparent aldose reductase activities may be ...

Ranirestat (also known as AS-3201) is an aldose reductase inhibitor being developed for the treatment of diabetic neuropathy by Dainippon Sumitomo Pharma and PharmaKyorin. It has been granted orphan drug status. The drug is to be used orally. A Canadian Phase III clinical trial has been completed. Phase III trials in Europe and the US started in June 2009 and are expected to complete in April 2013. Ranirestat is aldose reductase inhibitor that acts by reducing sorbitol accumulation in cells. Aldose reductase is an enzyme that catalyzes one of the steps in sorbitol (polyol) pathway which is responsible for formation of fructose from glucose. Aldose reductase activity is increased, parallel to glucose blood levels, in tissues that are not insulin sensitive, including lenses, peripheral nerves and renal glomeruli. Sorbitol does not diffuse through cell membranes easily and therefore accumulates in these tissues, causing osmotic damage, leading to retinopathy and neuropathy. Results from a Canadian ...

A 40.5-year-old man developed hypophosphataemia and osteomalacia following treatment with ferric carboxymaltose and iron sucrose for microcytic anaemia. Additionally, zoledronic acid and unspecified glucocorticoid contributed in osteomalacia [not all dosages and routes stated].. The man, with Crohn's disease (CD) presented to osteology outpatient clinic due to diffuse skeletal pain (lumbar and thoracic spine, ribs and lower extremities), progressive loss of mobility and gait disturbance. After clinical worsening (of persisting bone pain and gait disturbance), he received zoledronic acid. However, his symptoms did not improve over the subsequent months, thus, he was hospitalised. He had been receiving calcium and vitamin D supplementation, along with maintenance therapy of... ...

The crude ethyl acetate extract of the leaves of Cornus macrophylla showed antibacterial activity against Pseudomonas aeruginosa, a leading cause of illness in immunocompromised individuals. Bioactivity-guided separation led to the isolation of kaempferol 3-O-α-L-rhamnopyranoside (afzelin). The structure was determined based on evaluation of its spectroscopic (UV, MS, and NMR) data. The minimum inhibitory concentration (MIC) of afzelin against Pseudomonas aeruginosa was found to be 31 µg/mL. In addition, the results indicated that a hydroxyl group at C3 of the C-ring of the flavone skeleton and the rhamnose group may act as a negative factor and an enhancing factor, respectively, in the antibacterial activities of afzelin.

The reaction product of nitric oxide and superoxide, peroxynitrite, is a potent biological oxidant. The most important oxidative protein modifications described for peroxynitrite are cysteine-thiol oxidation and tyrosine nitration. We have previously demonstrated that intrinsic heme-thiolate (P450)-dependent enzymatic catalysis increases the nitration of tyrosine 430 in prostacyclin synthase and results in loss of activity which contributes to endothelial dysfunction. We here report the sensitive peroxynitrite-dependent nitration of an over-expressed and partially purified human prostacyclin synthase (3.3 μM) with an EC50 value of 5 μM. Microsomal thiols in these preparations effectively compete for peroxynitrite and block the nitration of other proteins up to 50 μM peroxynitrite. Purified, recombinant PGIS showed a half-maximal nitration by 10 μM 3-morpholino sydnonimine (Sin-1) which increased in the presence of bicarbonate, and was only marginally induced by freely diffusing NO2-radicals

Bone marrow oedema (BME) and avascular osteonecrosis (AVN) are disorders of unclear origin. Although there are numerous operative and non-operative treatments for AVN, pain management in patients with AVN remains challenging. Prostaglandins play an important role in inflammatory responses and cell differentiation. It is thought that prostaglandin I2 ([PGI2] or synonoma prostacyclin) and its analogues promote bone regeneration on a cellular or systemic level. The purpose of this study was to assess the curative and symptomatic efficacy of the prostacyclin analogue iloprost in BME and AVN patients. We are reporting on 50 patients (117 bones) affected by BME/AVN who were treated with iloprost. Pain levels before, during and 3 and 6 months after iloprost application were evaluated by a visual analogue scale (VAS). The short form(SF)-36 health survey served to judge general health status before and after treatment. Harris Hip Score (HHS) and Knee Society Score (KSS) were performed as functional scores and

The mixture is cooled in an ice-water bath and 10.9 M aqueous potassium hydroxide solution (7.02 mL, 76.5 mmol) is added over a period of 10 min. After 5 min, the ice-water bath is removed, and 13.5 g (30.6 mmol) of N-(4-Methoxybenzyl)-N-(3-phenylpropyl)-2-nitrobenzenesulfonamide in 20 mL of acetonitrile is added over 20 min. The reaction mixture is heated in a 50°C oil bath for 40 min (Note 10). The reaction mixture is allowed to cool to room temperature, diluted with 80 mL of water, and extracted with three 80-mL portions of dichloromethane . The combined organic extracts are washed with brine (80 mL), dried over magnesium sulfate , filtered, and concentrated under reduced pressure. The residue is purified by column chromatography on ...

Inositol 1,4,5-trisphosphate (IP3) is a ubiquitous intracellular messenger regulating diverse functions in almost all mammalian cell types. It is generated by membrane receptors that couple to phospholipase C (PLC), an enzyme which liberates IP3 from phosphatidylinositol 4,5-bisphosphate (PIP2). The major action of IP3, which is hydrophilic and thus translocates from the membrane into the cytoplasm, is to induce Ca2+ release from endogenous stores through IP3 receptors (IP3Rs). Cardiac excitation-contraction coupling relies largely on ryanodine receptor (RyR)-induced Ca2+ release from the sarcoplasmic reticulum. Myocytes express a significantly larger number of RyRs compared to IP3Rs (~100:1), and furthermore they experience substantial fluxes of Ca2+ with each heartbeat. Therefore, the role of IP3 and IP3-mediated Ca2+ signaling in cardiac myocytes has long been enigmatic. Recent evidence, however, indicates that despite their paucity cardiac IP3Rs may play crucial roles in regulating diverse ...

Although inositol trisphosphate receptors (IP3Rs) are best known for their roles in releasing calcium from intracellular stores in response to IP3, in cells that have close apposition of the endoplasmic or sarcoplasmic reticulum (ER/SR) to the plasma membrane, IP3Rs can also influence the influx of extracellular calcium. This action of IP3 as a regulator of extracellular calcium currents is important for regulation of vasoconstriction and vascular tone through an IP3-induced cation current (ICat) that results from an interaction between ER/SR IP3Rs and surface-localized transient receptor potential 3 (TRPC3) channels. Adebiyi et al. found that disruption of plasma membrane microdomains called caveolae, which are rich in cholesterol and associated with the scaffolding protein caveolin, reduced ICat, myogenic tone, and IP3-induced vasoconstriction of isolated rat cerebral artery smooth muscle cells or arterial preparations. Knockdown of caveolin-1 or introduction of a peptide corresponding to the ...

The cell-wall D-mannans of Candida parapsilosis, Endomycopsis fibuliger, Saccharomyces rouxii, Torulopsis apicola (Hajsig strain), and Torulopsis bombi were degraded with an exo alpha-D-mannosidase from Arthrobacter GJM-1 to their alpha-(1-6)-linked D-mannopyranose main-chains, as demonstrated by p.m.r. spectroscopy. D-Galacto-D-mannans from Candida lipolytica, Torulopsis gropengiesseri, Torulopsis lactis-condensi, Torulopsis magnoliae, and Trichosporon fermentans could be degraded to polysaccharides containing mainly 6-O-linked alpha-D-mannopyranosyl residues following preferential removal of their enzyme-resistant, D-galactopyranosyl non-reducing end-units with acid. The D-mannans of Saccharomyces lodderi, Citeromyces matritensis, and Pichia pastoris could also be enzymically degraded to polysaccharides containing predominantly alpha-(1-6)-linked D-mannopyranosyl residues after hydrolysis of most of the beta-D-linked residues in their side chains with acid. The exo alpha-D-mannosidase, as would be

TY - JOUR. T1 - Androgen Receptor Signalling Promotes a Luminal Phenotype in Mammary Epithelial Cells. AU - Tarulli, Gerard. AU - Laven-Law, Geraldine. AU - Shehata, Mona. AU - Walters, Kirsty.

N2 - Androgens influence mammary gland development but the specific role of the androgen receptor (AR) in mammary function is largely unknown. We identified cell subsets that express AR in vivo and determined the effect of AR activation and transgenic AR inhibition on sub-populations of the normal mouse mammary epithelium by flow cytometry and immunohistochemistry. Immunolocalisation of AR with markers of lineage identity was also performed in human breast tissues. AR activation in vivo significantly decreased the proportion of basal cells, and caused an accumulation of cells that expressed a basal cell marker but exhibited morphological features of ...

We have previously reported the substrate specificity of the cytosolic α-D-mannosidase purified from rat liver using Man9GlcNAc, i.e. Manα1-2Manα1-3(Manα1-2Manα1-6)Man α1-6(Manα1-2Manα1-2Manα1-3)Manβ1-4GlcNAc, as substrate [Grard, Saint-Pol, Haeuw, Alonso, Wieruszeski, Strecker and Michalski (1994) Eur. J. Biochem. 223, 99-106]. Man9GlcNAc is hydrolysed giving Man5GlcNAc, i.e. Manα1-2Manα1-2Manα1-3(Manα1-6)Manβ1-4GlcNAc, possessing the same structure as the oligosaccharide of the dolichol pathway formed in the cytosolic compartment during the biosynthesis of N-glycosylprotein glycans. We study here the activity of the purified cytosolic α-D-mannosidase towards the oligosaccharide-diphosphodolichol intermediates formed during the biosynthesis of N-glycans, and also towards soluble oligosaccharides released from the endoplasmic reticulum which are glucosylated or not and possessing at their reducing end either a single N-acetylglucosamine residue or a di-N-acetylchitobiose ...
