Arginine methylation and binding of Hrp1p to the efficiency element for mRNA 3'-end formation. (1/10469)

Hrp1p is a heterogeneous ribonucleoprotein (hnRNP) from the yeast Saccharomyces cerevisiae that is involved in the cleavage and polyadenylation of the 3'-end of mRNAs and mRNA export. In addition, Hrplp is one of several RNA-binding proteins that are posttranslationally modified by methylation at arginine residues. By using functional recombinant Hrp1p, we have identified RNA sequences with specific high affinity binding sites. These sites correspond to the efficiency element for mRNA 3'-end formation, UAUAUA. To examine the effect of methylation on specific RNA binding, purified recombinant arginine methyltransferase (Hmt1p) was used to methylate Hrp1p. Methylated Hrp1p binds with the same affinity to UAUAUA-containing RNAs as unmethylated Hrpl p indicating that methylation does not affect specific RNA binding. However, RNA itself inhibits the methylation of Hrp1p and this inhibition is enhanced by RNAs that specifically bind Hrpl p. Taken together, these data support a model in which protein methylation occurs prior to protein-RNA binding in the nucleus.  (+info)

Gamma interferon stimulates rat alveolar macrophages to kill Pneumocystis carinii by L-arginine- and tumor necrosis factor-dependent mechanisms. (2/10469)

Pneumocystis carinii pneumonia remains a serious complication for immunocompromised patients. In the present study, P. carinii organisms interacted with gamma interferon (IFN-gamma)-stimulated alveolar macrophages (AMs) to activate the L-arginine-dependent cytocidal pathway involving reactive nitrogen intermediates (RNI) that were assayed as nitrite (NO2-). Unstimulated cultures of AMs produced negligible quantities of RNI. Addition of P. carinii organisms to IFN-gamma-primed AMs resulted in greatly enhanced production of RNI. NO2- levels increased from 0.8 +/- 0.4 to 11.1 +/- 3.8 microM as early as 6 h after P. carinii organisms were incubated with IFN-gamma-stimulated AMs and to 35.1 +/- 8.9 microM after a 24-h incubation, a near-maximum level. High levels of NO2- were produced by AMs primed with as little as 10 U of IFN-gamma per ml in the presence of P. carinii, and a 20-fold increase in IFN-gamma concentration resulted in only a further 65% increase in NO2- production. RNI-dependent killing of P. carinii was demonstrated by both a 51Cr release assay and a [35S]methionine pulse immunoprecipitation assay. Addition of either monoclonal tumor necrosis factor alpha (TNF-alpha) neutralizing antibody or 200 microM NG-monomethyl-L-arginine (L-NGMMA), a competitive inhibitor of the L-arginine-dependent pathway, significantly decreased NO2- production and reduced P. carinii killing. TNF-alpha alone had no effect on P. carinii viability. These results suggest that (i) the specific interaction of P. carinii organisms with IFN-gamma-primed AMs triggers the production of RNI, (ii) RNI are toxic to P. carinii, and (iii) TNF-alpha likely plays a central role in mediating P. carinii killing by IFN-gamma-stimulated AMs.  (+info)

Inhibition of transforming growth factor beta production by nitric oxide-treated chondrocytes: implications for matrix synthesis. (3/10469)

OBJECTIVE: Nitric oxide (NO) is generated copiously by articular chondrocytes activated by interleukin-1beta (IL-1beta). If NO production is blocked, much of the IL-1beta inhibition of proteoglycan synthesis is prevented. We tested the hypothesis that this inhibitory effect of NO on proteoglycan synthesis is secondary to changes in chondrocyte transforming growth factor beta (TGFbeta). METHODS: Monolayer, primary cultures of lapine articular chondrocytes and cartilage slices were studied. NO production was determined as nitrite accumulation in the medium. TGFbeta bioactivity in chondrocyte- and cartilage-conditioned medium (CM) was measured with the mink lung epithelial cell bioassay. Proteoglycan synthesis was measured as the incorporation of 35S-sodium sulfate into macromolecules separated from unincorporated label by gel filtration on PD-10 columns. RESULTS: IL-1beta increased active TGFbeta in chondrocyte CM by 12 hours; by 24 hours, significant increases in both active and latent TGFbeta were detectable. NG-monomethyl-L-arginine (L-NMA) potentiated the increase in total TGFbeta without affecting the early TGFbeta activation. IL-1beta stimulated a NO-independent, transient increase in TGFbeta3 at 24 hours; however, TGFbeta1 was not changed. When NO synthesis was inhibited with L-NMA, IL-1beta increased CM concentrations of TGFbeta1 from 24-72 hours of culture. L-arginine (10 mM) reversed the inhibitory effect of L-NMA on NO production and blocked the increases in TGFbeta1. Anti-TGFbeta1 antibody prevented the restoration of proteoglycan synthesis by chondrocytes exposed to IL-1beta + L-NMA, confirming that NO inhibition of TGFbeta1 in IL-1beta-treated chondrocytes effected, in part, the decreased proteoglycan synthesis. Furthermore, the increase in TGFbeta and proteoglycan synthesis seen with L-NMA was reversed by the NO donor S-nitroso-N-acetylpenicillamide. Similar results were seen with cartilage slices in organ culture. The autocrine increase in CM TGFbeta1 levels following prior exposure to TGFbeta1 was also blocked by NO. CONCLUSION: NO can modulate proteoglycan synthesis indirectly by decreasing the production of TGFbeta1 by chondrocytes exposed to IL-1beta. It prevents autocrine-stimulated increases in TGFbeta1, thus potentially diminishing the anabolic effects of this cytokine in chondrocytes.  (+info)

Phe161 and Arg166 variants of p-hydroxybenzoate hydroxylase. Implications for NADPH recognition and structural stability. (4/10469)

Phe161 and Arg166 of p-hydroxybenzoate hydroxylase from Pseudomonas fluorescens belong to a newly discovered sequence motif in flavoprotein hydroxylases with a putative dual function in FAD and NADPH binding [1]. To study their role in more detail, Phe161 and Arg166 were selectively changed by site-directed mutagenesis. F161A and F161G are catalytically competent enzymes having a rather poor affinity for NADPH. The catalytic properties of R166K are similar to those of the native enzyme. R166S and R166E show impaired NADPH binding and R166E has lost the ability to bind FAD. The crystal structure of substrate complexed F161A at 2.2 A is indistinguishable from the native enzyme, except for small changes at the site of mutation. The crystal structure of substrate complexed R166S at 2.0 A revealed that Arg166 is important for providing an intimate contact between the FAD binding domain and a long excursion of the substrate binding domain. It is proposed that this interaction is essential for structural stability and for the recognition of the pyrophosphate moiety of NADPH.  (+info)

Possible role for ligand binding of histidine 81 in the second transmembrane domain of the rat prostaglandin F2alpha receptor. (5/10469)

For the five principal prostanoids PGD2, PGE2, PGF2alpha, prostacyclin and thromboxane A2 eight receptors have been identified that belong to the family of G-protein-coupled receptors. They display an overall homology of merely 30%. However, single amino acids in the transmembrane domains such as an Arg in the seventh transmembrane domain are highly conserved. This Arg has been identified as part of the ligand binding pocket. It interacts with the carboxyl group of the prostanoid. The aim of the current study was to analyze the potential role in ligand binding of His-81 in the second transmembrane domain of the rat PGF2alpha receptor, which is conserved among all PGF2alpha receptors from different species. Molecular modeling suggested that this residue is located in close proximity to the ligand binding pocket Arg 291 in the 7th transmembrane domain. The His81 (H) was exchanged by site-directed mutagenesis to Gln (Q), Asp (D), Arg (R), Ala (A) and Gly (G). The receptor molecules were N-terminally extended by a Flag epitope for immunological detection. All mutant proteins were expressed at levels between 50% and 80% of the wild type construct. The H81Q and H81D receptor bound PGF2alpha with 2-fold and 25-fold lower affinity, respectively, than the wild type receptor. Membranes of cells expressing the H81R, H81A or H81G mutants did not bind significant amounts of PGF2alpha. Wild type receptor and H81Q showed a shallow pH optimum for PGF2alpha binding around pH 5.5 with almost no reduction of binding at higher pH. In contrast the H81D mutant bound PGF2alpha with a sharp optimum at pH 4.5, a pH at which the Asp side chain is partially undissociated and may serve as a hydrogen bond donor as do His and Gln at higher pH values. The data indicate that the His-81 in the second transmembrane domain of the PGF2alpha receptor in concert with Arg-291 in the seventh transmembrane domain may be involved in ligand binding, most likely not by ionic interaction with the prostaglandin's carboxyl group but rather as a hydrogen bond donor.  (+info)

R73A and H144Q mutants of the yeast mitochondrial cyclophilin Cpr3 exhibit a low prolyl isomerase activity in both peptide and protein-folding assays. (6/10469)

Previously we reported that the R73A and H144Q variants of the yeast cyclophilin Cpr3 were virtually inactive in a protease-coupled peptide assay, but retained activity as catalysts of a proline-limited protein folding reaction [Scholz, C. et al. (1997) FEBS Lett. 414, 69-73]. A reinvestigation revealed that in fact these two mutations strongly decrease the prolyl isomerase activity of Cpr3 in both the peptide and the protein-folding assay. The high folding activities found previously originated from a contamination of the recombinant Cpr3 proteins with the Escherichia coli protein SlyD, a prolyl isomerase that co-purifies with His-tagged proteins. SlyD is inactive in the peptide assay, but highly active in the protein-folding assay.  (+info)

The stimulatory effects of Hofmeister ions on the activities of neuronal nitric-oxide synthase. Apparent substrate inhibition by l-arginine is overcome in the presence of protein-destabilizing agents. (7/10469)

A variety of monovalent anions and cations were effective in stimulating both calcium ion/calmodulin (Ca2+/CaM)-independent NADPH-cytochrome c reductase activity of, and Ca2+/CaM-dependent nitric oxide (NO.) synthesis by, neuronal nitric oxide synthase (nNOS). The efficacy of the ions in stimulating both activities could be correlated, in general, with their efficacy in precipitating or stabilizing certain proteins, an order referred to as the Hofmeister ion series. In the hemoglobin capture assay, used for measurement of NO. production, apparent substrate inhibition by L-arginine was almost completely reversed by the addition of sodium perchlorate (NaClO4), one of the more effective protein-destabilizing agents tested. Examination of this phenomenon by the assay of L-arginine conversion to L-citrulline revealed that the stimulatory effect of NaClO4 on the reaction was observed only in the presence of oxyhemoglobin or superoxide anion (generated by xanthine and xanthine oxidase), both scavengers of NO. Spectrophotometric examination of nNOS revealed that the addition of NaClO4 and a superoxide-generating system, but neither alone, prevented the increase of heme absorption at 436 nm, which has been attributed to the nitrosyl complex. The data are consistent with the release of autoinhibitory NO. coordinated to the prosthetic group of nNOS, which, in conjunction with an NO. scavenger, causes stimulation of the reaction.  (+info)

Cystic fibrosis-associated mutations at arginine 347 alter the pore architecture of CFTR. Evidence for disruption of a salt bridge. (8/10469)

Arginine 347 in the sixth transmembrane domain of cystic fibrosis transmembrane conductance regulator (CFTR) is a site of four cystic fibrosis-associated mutations. To better understand the function of Arg-347 and to learn how mutations at this site disrupt channel activity, we mutated Arg-347 to Asp, Cys, Glu, His, Leu, or Lys and examined single-channel function. Every Arg-347 mutation examined, except R347K, had a destabilizing effect on the pore, causing the channel to flutter between two conductance states. Chloride flow through the larger conductance state was similar to that of wild-type CFTR, suggesting that the residue at position 347 does not interact directly with permeating anions. We hypothesized that Arg-347 stabilizes the channel through an electrostatic interaction with an anionic residue in another transmembrane domain. To test this, we mutated anionic residues (Asp-924, Asp-993, and Glu-1104) to Arg in the context of either R347E or R347D mutations. Interestingly, the D924R mutation complemented R347D, yielding a channel that behaved like wild-type CFTR. These data suggest that Arg-347 plays an important structural role in CFTR, at least in part by forming a salt bridge with Asp-924; cystic fibrosis-associated mutations disrupt this interaction.  (+info)

Background Fetal Growth Restriction is often associated with a feto-placental vascular dysfunction conceivably involving endothelial cells. Our study aimed to verify this pathogenic role for feto-placental endothelial cells and, coincidentally, demonstrate any abnormality in the nitric oxide system. Methods Prenatal assessment of feto-placental vascular function was combined with measurement of nitric oxide (in the form of S-nitrosohemoglobin) and its nitrite byproduct, and of the endogenous nitric oxide synthase inhibitor asymmetric dimethylarginine. Umbilical vein endothelial cells were also harvested to determine their gene profile. The study comprised term pregnancies with normal (n = 40) or small-for-gestational-age (n = 20) newborns, small-for-gestational-age preterm pregnancies (n = 15), and bi-chorial, bi-amniotic twin pregnancies with discordant fetal growth (n = 12).

BACKGROUND Nitric oxide (NO) plays an important part in lowering pulmonary vascular resistance after birth, and in persistent pulmonary hypertension of the newborn (PPHN), NO-mediated dilation is dysfunctional. The endogenous NO synthase inhibitor asymmetric dimethylarginine (ADMA) circulates in plasma, and its concentrations are elevated in certain cardiovascular diseases, including pulmonary hypertension. ADMA is metabolized by the enzyme dimethylarginine dimethylaminohydrolase (DDAH), the activity of which regulates ADMA concentrations and provides a mechanism for modulating NO synthase in vivo. We investigated the changes in expression and activity of the 2 isoforms of DDAH in lungs from newborn piglets both during normal development and in PPHN. METHODS AND RESULTS Using Western blotting, we showed that DDAHI expression did not change in the normal developing lung; however, DDAHII increased after birth and reached a peak at 1 day. This was reflected in an increase in total DDAH activity according

Arginine supplementation has been shown to alleviate endothelial dysfunction and improve exercise performance through increasing nitric oxide production in patients with cardiopulmonary diseases. In addition, arginine supplementation could decrease accumulations of lactate and ammonia, metabolites involved in development of muscular fatigue. The aim of this study was to investigate the effect of short-term arginine supplementation on performance in intermittent anaerobic exercise and the underlying mechanism in well-trained male athletes. Ten elite male college judo athletes participated with a randomized crossover, placebo-controlled design. The subjects consumed 6 g/day arginine (ARG trial) or placebo (CON trial) for 3 days then performed an intermittent anaerobic exercise test on a cycle ergometer. Blood samples were collected before supplementation, before and during exercise and 0, 3, 6, 10, 30 and 60 min after exercise. ARG trial had significantly higher arginine concentrations than CON ...

Arginine (ARG) and nitric oxide maintain the mucosal integrity of the intestine in various intestinal disorders. In the present study, we evaluated the effects of oral ARG supplementation on intestinal structural changes, enterocyte proliferation and apoptosis following methotrexate (MTX)-induced intestinal damage in a rat. Male rats were divided into four experimental groups: Control rats, CONTR-ARG rats, were treated with oral ARG given in drinking water 72 hours before and 72 hours following vehicle injection, MTX rats were treated with a single dose of methotrexate, and MTX-ARG rats were treated with oral ARG following injection of MTX. Intestinal mucosal damage, mucosal structural changes, enterocyte proliferation and enterocyte apoptosis were determined 72 hours following MTX injection. RT-PCR was used to determine bax and bcl-2 mRNA expression. MTX-ARG rats demonstrated greater jejunal and ileal bowel weight, greater ileal mucosal weight, greater ileal mucosal DNA and protein levels, greater

In this study, SNP rs1241321 in DDAH1 was found to be associated with a higher risk of type 2 diabetes independently of the plasma ADMA level. In addition, individuals with an AA genotype at rs1241321 appeared to be more insulin-sensitive when compared with AG/GG individuals. Over a median follow-up period of 28.2 months, AA genotype at rs1241321 was associated with better long-term clinical outcome in diabetic subgroup. In contrast, some SNPs of DDAH1, especially the rs1498373, might influence the plasma level of ADMA. However, with the exception of rs1241321, none of these SNPs or the plasma ADMA level was associated with type 2 diabetes, suggesting that the interaction of DDAH1 variants with type 2 diabetes may not be directly related to its enzymatic activity, i.e. not just simply mediated by the plasma ADMA level. We also identified a common haplotype H5 (GGCAGC) that was associated with reduced risk of type 2 diabetes.. It is well recognized that type 2 diabetes and its metabolic ...

TY - JOUR. T1 - Role of l-arginine in nitric oxide production in health and hypertension. AU - Rajapakse, Niwanthi W.. AU - Mattson, David L.. PY - 2009/3. Y1 - 2009/3. N2 - l-Arginine is the substrate for vascular nitric oxide (NO) formation. Under normal physiological conditions, intracellular l-arginine levels far exceed the Km of NO synthase for l-arginine. However, endogenous NO formation is dependent on extracellular l-arginine concentrations, giving rise to the concept of the l-arginine paradox. Nitric oxide production in epithelial and endothelial cells is closely coupled to cellular l-arginine uptake, indicating that l-arginine transport mechanisms play a major role in the regulation of NO-dependent function. Consistent with the data in endothelial and epithelial cells are functional data indicating that exogenous l-arginine can increase renal vascular and tubular NO bioavailability and thereby influence kidney perfusion, function and arterial pressure.

Elevated levels of asymmetric dimethylarginine (ADMA) and symmetric dimethylarginine (SDMA) are accompanied by endothelial dysfunction and predict adverse outcome after ischemic stroke. Via induction of oxidative stress, dimethylarginines are possibly linked to the inflammatory cascade after stroke that is known to considerably contribute to secondary progression of brain injury. We sought to investigate the association between dimethylarginines and inflammatory mediators in patients with acute ischemic stroke. Plasma levels of ADMA and SDMA were measured in prospectively collected blood samples of 58 patients with acute ischemic stroke. Blood samples were taken at 6 hours, 12 hours, 24 hours, 3 days and 7 days after onset of symptoms. Analyses of ADMA and SDMA were done by high-performance liquid chromatography-tandem mass spectrometry.

Background: Asymmetric dimethylarginine (ADMA) and NG-monomethyl-L-arginine (NMMA), endogenous nitric oxide-synthase inhibitors (End-NOSI), have been associated with cardiovascular risk factors (CVRF) and atherosclerosis. In addition, acute administration of NOSI cause hypertension through hemodynamic effects, but whether circulating End-NOSI are associated with these abnormalities is unknown.. Methods: We studied 922 adults in a population-based study (PREVENCION study). We examined the correlation between End-NOSI/L-arginine and CVRF, as well as the relationship between these biomarkers and arterial hemodynamics, carotid-femoral pulse wave velocity (cf-PWV) and carotid intima-media thickness (c-IMT). We used general linear modeling for statistical analyses. Estimates (β) are standardized.. Results: In multivariate analyses, LDL-cholesterol and C-reactive protein (CRP) were independent predictors of ADMA, whereas LDL-cholesterol and gender independently predicted NMMA. Age, gender, ...

Effects of Growth Hormone on the Nitric Oxide Pathway - Full Text View - ClinicalTrials.govEffects of Growth Hormone on the Nitric Oxide Pathway - Full Text View - ClinicalTrials.gov
Nitric oxide (NO) is a potent endogenous vasodilator and has shown to inhibit key processes of atherosclerosis like monocyte adhesion, platelet aggregation, and vascular smooth muscle cell proliferation. Impaired endothelial NO production is a main feature of endothelial dysfunction, which by itself is an early step in the course of atherosclerotic vascular disease.. Recent studies could confirm this close association between parameters of the NO pathway and cardiovascular disease and could further enhance the knowledge on the pathophysiological mechanisms. There is a significant relationship between insulin resistance and the endogenous NO synthase inhibitor asymmetric dimethylarginine (ADMA). Moreover, evidence could be provided that plasma levels of ADMA are a strong and independent predictor of mortality and cardiovascular outcome in haemodialysis patients.. Patients with growth hormone deficiency are characterized by a 1.9 fold higher risk of death from cardiovascular disease. Again, there ...

The main finding in this study is that in essential hypertensives the endogenous inhibitor of e-NOS ADMA is inversely related to endothelial function as measured by the peak hemodynamic response to ACh. Such relationship occurs in a range of ADMA values within the boundaries of the normal range. A companion, unexpected, finding in this study is that circulating L-arginine is directly related to plasma ADMA and, like plasma ADMA, it is inversely related to endothelial function.. The importance of ADMA as an endogenous inhibitor of e-NOS is now well established (26-28). Elegant studies in healthy volunteers convincingly demonstrated that intravenous ADMA infusion at a dose resulting in pathophysiological concentrations augments peripheral and renovascular resistance and arterial pressure (22). High plasma ADMA concentration was observed in the presence of traditional or emerging cardiovascular risk factors (e.g., hyperhomocysteinemia) (18-21,29), inducing endothelial dysfunction in some of these ...

Depletion of Arginine by Recombinant Arginine Deiminase Induces nNOS-Activated Neurotoxicity in Neuroblastoma CellsDepletion of Arginine by Recombinant Arginine Deiminase Induces nNOS-Activated Neurotoxicity in Neuroblastoma Cells
The abnormal regulation of inducible nitric oxide synthase (iNOS) and neuronal nitric oxide synthase (nNOS) is associated with neurodegenerative disorders. Recombinant arginine deiminase (rADI) is a selective NO modulator of iNOS and eNOS in endothelial cells, and it also exhibits neuroprotective activity in an iNOS-induced neuron-microglia coculture system. However, the effect of rADI on nNOS remains unknown. Addressing this issue is important for evaluating the potential application of rADI in neurodegenerative diseases. SH-SY5Y cells were treated with |i|N|/i|-methyl-D-aspartic acid (NMDA) to activate nNOS. NMDA increased NO production by 39.7 ± 3.9% via nNOS under arginine-containing conditions, but there was no significant increase in both arginine-free and rADI pretreated arginine-containing (citrulline) buffer. Subsequently, neither NMDA nor rADI alone caused cytotoxicity, whereas cotreatment with NMDA and rADI resulted in dissipation of the cell mitochondrial membrane potential and

BACKGROUND: Asymmetric dimethylarginine (ADMA) has been suggested as a possible marker of endothelial dysfunction, and interest in its use in clinical practice is increasing. However, the potential role of symmetric dimethylarginine (SDMA) as an endogenous marker of renal function, has been less widely investigated. The aims of the present study were therefore to determine reference values for dimethylarginines in plasma after method validation, and to ascertain ADMA plasma concentrations in patients with disorders characterized by endothelial dysfunction; a further end-point was to investigate the relationship between SDMA plasma concentrations and estimated GFR (eGFR) as well as plasmatic creatinine in patients with chronic kidney disease (CKD ...

A healthy adult generates 300 mol (~60 mg) of ADMA per day [9]. Bode-Bogers found a significant increase in plasma levels of ADMA in subjects more than 70 years [10]. By inhibiting NO bioavailability, ADMA causes endothelial dysfunction, vasoconstriction, blood pressure elevation and atherosclerosis [11C16]. Increasing evidence reveals that elevated ADMA is associated with many diseases such as peripheral arterial disease, coronary artery disease, preeclampsia, hypertension, heart stroke, heart failing, chronic kidney disease, portal hypertension in cirrhosis, diabetes mellitus, and insulin level of resistance ...

L-Citrulline Malate: A compound consisting of Citrulline, a nonessential amino acid. It plays a vital role in many important biological processes including regulating nitric oxide production, helping to eliminate the burn associated with lactic acid build up, reducing the negative effects of ammonia and bacterial endo toxins on performance, increasing the rate of muscle ATP (Andenosine Triphosphate, the major energy source within the cell) production during exercise and greater phosphocreatine recovery after exercise. In fact, L-Citrulline Malate seems to increase plasma Arginine levels better than taking the amino acid Arginine itself! If the enhanced pumps and improved nutrient delivery properties are the reason you are using Arginine based NO products, you need to pay close attention to L-Citrulline Malate as this may result in muscles that can keep on going and going…completely smashing the aerobic threshold ...

What is Arginine?. The amino acid Arginine (l-Arginine HCl) is acquiring a reputation for keeping the bodys biggest muscle, the heart, in tip-top shape. In addition to the heart, Arginine can also needed to increase protein synthesis which can in turn increase cels. Studies have found that men with low sperm counts experienced an increase in the number of sperm when they were supplemented with Arginine. How does it work?. Arginine supplements appear to reduce mildly elevated blood pressure by enhancing the synthesis of Nitric Oxide (a gas) in the cells lining the blood vessels. This helps dilate vessel walls and improves blood flow around the heart. In fact, Nitric Oxide ranks as the bodys most potent blood vessel expander. In addition, Arginine may help in treating male fertility caused by circulation problems. Where does it come from?. Arginine is an amino acid found in many foods, including dairy products, meat, poultry, fish, nuts and chocolate. Safety / Side Effects. Arginine has so far ...

The current study confirms previous observations of our group and others that oxidized lipoprotein increases the endothelial release of ADMA and that ADMA reduces the synthesis of NO while increasing the generation of superoxide anion. However, in this study it took rather high concentrations (10 μm) of exogenous ADMA to have a measurable effect upon NO synthesis, superoxide anion generation and endothelial adhesiveness. This concentration of ADMA is at the upper range of plasma ADMA levels observed in disease (2 to 10 μm).. However, chronic exposure to the lower levels of ADMA observed in disease states appears to have similar effects on endothelial biology as does short-term exposure to the higher dose used in this study. Specifically, we and others have demonstrated that the two to three-fold increase in plasma ADMA observed in hypercholesterolemic individuals is associated with reductions in endothelium dependent vasodilation and urinary nitrate excretion-effects that are reversed by ...

NO is biosynthesized from the amino acid arginine, meaning increased consumption of arginine ought to boost greater production of NO. However, arginine is poorly absorbed by the intestine and is quickly broken down by the liver, which reduces its capacity to increase NO production and making it a poor choice for increasing NO. On the other hand, the amino acid citrulline, which is quickly converted in the body into arginine, is more effectively absorbed by the intestines and avoids breakdown by the liver. Consequently, taking AML Preworkout, which contains citrulline (as citrulline-malate), represents a fantastic way to vigorously increase endogenous arginine levels and drive NO production for considerably improved stamina. AML Preworkout does not contain agmatine (Decarboxilated form of arginine), which may inhibit NO production ...

L-Arginine capsules contain 700 mg pure, crystalline L-arginine. L-arginine is a conditionally essential dibasic amino acid. It is needed for tissue protein synthesis and ammonia detoxification via urea acid cycle. L-arginine can either be used for glucose synthesis or catabolized to produce energy via the tricarboxylic acid cycle. L-arginine is required for the synthesis of creatine phosphate which functions as a carrier of readily available energy for contractile work in muscles. L-arginine is also a precursor of polyamines, including putrescine, spermine and spermidine that act as physiological growth regulators of cell proliferation, and are involved in the stabilization of cell membranes and cell organelles. L-arginine is a potent stimulator of insulin, glucagon, and growth hormone release, and functions as a representative signal to the endocrine system that dietary protein ingestion has taken place.

L-Arginine and Nitric Oxide: What You Need to Know | Dr Nibber
arolinska Institute in Sweden found that NO could be generated from nitrates that were abundant in green leafy vegetables like spinach, lettuce, kale and especially beetroot. This requires the activation of the NOx 3,2,1 pathway to be fully operational. In effect, nitrates consumed in foods are reduced by oral bacteria into nitrites and then in the stomach into NO.. Since then, other research groups have joined the effort to uncover nitrates amazing ability to generate NO that is quicker and much more efficient than the previously known pathway via the amino acid l-arginine. Unlike, l-arginine which is only operational in conditions with good oxygen and is dependent on the proper functioning of a family of enzymes called nitric oxide synthases (NOS), nitrates offer an alternate pathway (albeit a backup) for the body to generate the versatile NO molecule quickly at low doses and in low oxygen conditions! The latter is an important factor especially during a number of pathologies where oxygen is ...

Citrulline: a potential immunomodulator in sepsis. - Science ExchangeCitrulline: a potential immunomodulator in sepsis. - Science Exchange
BACKGROUNDSepsis leads to a complex systemic response of cytokines (both pro- and anti-inflammatory) and more recently recognized adipokine mediators. Endothelial nitric oxide (NO) may be a key component in regulating this response, but the pharmacologic manipulation of endothelial NO via L-arginine supplementation or inhibitors has provided inconsistent clinical data related to outcomes. These failures are related to the metabolism of L-arginine in the liver, toxicity of L-arginine, and asymmetric dimethylarginine inhibition, all of which may explain the arginine paradox. L-citrulline (CIT) offers a potentially valuable means of supplementing arginine and therefore impacting favorably NO availability. The goal of this study was to determine whether CIT supplementation altered the systemic response of mediators and cytokines in a rat model of sepsis with varying degrees of severity.METHODSSepsis was induced with 2 models of cecal ligation and puncture (CLP) of varying severity in Wistar rats. ...

cSNP analysis of the ABCA1 gene: Common variant lowers riskfor coronary artery diseasecSNP analysis of the ABCA1 gene: Common variant lowers riskfor coronary artery disease
Haydens investigation of variation within the ABCA1 gene was prompted by the finding that Tangier disease, characterized by almost a complete absence of HDL-C, is caused by a defect in ABCA1. This led Haydens team to search for other variants of the cholesterol transporter gene that might modify the risk of heart disease.. The researchers identified 16 single nucleotide polymorphisms (SNPs) a specific type of variation within the coding region of the ABCA1 gene. Of these, 10 caused amino acid changes in the protein, which have the potential to alter the function of the transporter. In the R219K variant the amino acid arginine is replaced with lysine. The authors note that the SNPs tend to be concentrated away from the functional regions of the transporter protein. They suggest that this may be why most variations seem to exert such minor effects. Defective ABC transporters have been implicated in a number of diseases: ABCA1 in Tangier disease, ABCC7, which transports chloride ions, in cystic ...
