An octapeptide that is a potent but labile vasoconstrictor. It is produced from angiotensin I after the removal of two amino acids at the C-terminal by ANGIOTENSIN CONVERTING ENZYME. The amino acid in position 5 varies in different species. To block VASOCONSTRICTION and HYPERTENSION effect of angiotensin II, patients are often treated with ACE INHIBITORS or with ANGIOTENSIN II TYPE 1 RECEPTOR BLOCKERS.
A peptidyl-dipeptidase that catalyzes the release of a C-terminal dipeptide, -Xaa-*-Xbb-Xcc, when neither Xaa nor Xbb is Pro. It is a Cl(-)-dependent, zinc glycoprotein that is generally membrane-bound and active at neutral pH. It may also have endopeptidase activity on some substrates. (From Enzyme Nomenclature, 1992) EC 220.127.116.11.
A BLOOD PRESSURE regulating system of interacting components that include RENIN; ANGIOTENSINOGEN; ANGIOTENSIN CONVERTING ENZYME; ANGIOTENSIN I; ANGIOTENSIN II; and angiotensinase. Renin, an enzyme produced in the kidney, acts on angiotensinogen, an alpha-2 globulin produced by the liver, forming ANGIOTENSIN I. Angiotensin-converting enzyme, contained in the lung, acts on angiotensin I in the plasma converting it to ANGIOTENSIN II, an extremely powerful vasoconstrictor. Angiotensin II causes contraction of the arteriolar and renal VASCULAR SMOOTH MUSCLE, leading to retention of salt and water in the KIDNEY and increased arterial blood pressure. In addition, angiotensin II stimulates the release of ALDOSTERONE from the ADRENAL CORTEX, which in turn also increases salt and water retention in the kidney. Angiotensin-converting enzyme also breaks down BRADYKININ, a powerful vasodilator and component of the KALLIKREIN-KININ SYSTEM.
An alpha-globulin of about 453 amino acids, depending on the species. It is produced by the liver and secreted into blood circulation. Angiotensinogen is the inactive precursor of natural angiotensins. Upon successive enzyme cleavages, angiotensinogen yields angiotensin I, II, and III with amino acids numbered at 10, 8, and 7, respectively.
Angiotensin-Converting Enzyme Inhibitors
A class of drugs whose main indications are the treatment of hypertension and heart failure. They exert their hemodynamic effect mainly by inhibiting the renin-angiotensin system. They also modulate sympathetic nervous system activity and increase prostaglandin synthesis. They cause mainly vasodilation and mild natriuresis without affecting heart rate and contractility.
A potent and specific inhibitor of PEPTIDYL-DIPEPTIDASE A. It blocks the conversion of ANGIOTENSIN I to ANGIOTENSIN II, a vasoconstrictor and important regulator of arterial blood pressure. Captopril acts to suppress the RENIN-ANGIOTENSIN SYSTEM and inhibits pressure responses to exogenous angiotensin.
Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation.
Chromatography, High Pressure Liquid
Antidiuretic hormones released by the NEUROHYPOPHYSIS of all vertebrates (structure varies with species) to regulate water balance and OSMOLARITY. In general, vasopressin is a nonapeptide consisting of a six-amino-acid ring with a cysteine 1 to cysteine 6 disulfide bridge or an octapeptide containing a CYSTINE. All mammals have arginine vasopressin except the pig with a lysine at position 8. Vasopressin, a vasoconstrictor, acts on the KIDNEY COLLECTING DUCTS to increase water reabsorption, increase blood volume and blood pressure.

The subtype 2 of angiotensin II receptors and pressure-natriuresis in adult rat kidneys. (1/383)The present work examined the effects of the subtype 2 of angiotensin II (AT2) receptors on the pressure-natriuresis using a new peptide agonist, and the possible involvement of cyclic guanosine 3', 5' monophosphate (cyclic GMP) in these effects. In adult anaesthetized rats (Inactin, 100 mg kg(-1), i.p.) deprived of endogenous angiotensin II by angiotensin converting enzyme inhibition (quinapril, 10 mg kg(-1), i.v.), T2-(Ang II 4-8)2 (TA), a highly specific AT2 receptor agonist (5, 10 and 30 microg kg(-1) min(-1), i.v.) or its solvent was infused in four groups. Renal functions were studied at renal perfusion pressures (RPP) of 90, 110 and 130 mmHg and urinary cyclic GMP excretion when RPP was at 130 mmHg. The effects of TA (10 microg kg(-1) min(-1)) were reassessed in animals pretreated with PD 123319 (PD, 50 microg kg(-1) min(-1), i.v.), an AT2 receptor antagonist and the action of the same dose of PD alone was also determined. Increases in RPP from 90 to 130 mmHg did not change renal blood flow (RBF) but induced 8 and 15 fold increases in urinary flow and sodium excretion respectively. The 5 microg kg(-1) min(-1) dose of TA was devoid of action. The 10 and 30 microg kg(-1) min(-1) doses did not alter total RBF and glomerular filtration rate, but blunted pressure-diuresis and natriuresis relationships. These effects were abolished by PD. TA decreased urinary cyclic GMP excretion. After pretreatment with PD, this decrease was reversed to an increase which was also observed in animals receiving PD alone. In conclusion, renal AT2 receptors oppose the sodium and water excretion induced by acute increases in blood pressure and this action cannot be directly explained by changes in cyclic GMP. (+info)
Cardiac growth factors in human hypertrophy. Relations with myocardial contractility and wall stress. (2/383)The aim of the present study was to investigate whether and which cardiac growth factors are involved in human hypertrophy, whether growth factor synthesis is influenced by overload type and/or by the adequacy of the hypertrophy, and the relationships between cardiac growth factor formation and ventricular function. Cardiac growth factor formation was assessed by measuring aorta-coronary sinus concentration gradient in patients with isolated aortic stenosis (n=26) or regurgitation (n=15) and controls (n=12). Gene expression and cellular localization was investigated in ventricular biopsies using reverse transcriptase-polymerase chain reaction and in situ hybridization. Cardiac hypertrophy with end-systolic wall stress <90 kdyne/cm2 was associated with a selective increased formation of insulin-like growth factor (IGF)-I in aortic regurgitation and of IGF-I and endothelin (ET)-1 in aortic stenosis. mRNA levels for IGF-I and preproET-1 were elevated and mainly expressed in cardiomyocytes. At stepwise analysis, IGF-I formation was correlated to the mean velocity of circumferential fiber shortening (r=0.86, P<0.001) and ET-1 formation to relative wall thickness (r=0.82, P<0. 001). When end-systolic wall stress was >90 kdyne/cm2, IGF-I and ET-1 synthesis by cardiomyocytes was no longer detectable, and only angiotensin (Ang) II was generated, regardless of the type of overload. The mRNA level for angiotensinogen was high, and the mRNA was exclusively expressed in the interstitial cells. Ang II formation was positively correlated to end-systolic stress (r=0.89, P<0.001) and end-diastolic stress (r=0.84, P<0.001). Multivariate stepwise analysis selected end-systolic stress as the most predictive variable and left ventricular end-diastolic pressure as the independent variable for Ang II formation (r=0.93, P<0.001). In conclusion, the present results indicate that the course of human left ventricular hypertrophy is characterized by the participation of different cardiac growth factors that are selectively related both to the type of hemodynamic overload and to ventricular function.

Angiotensin regulates the selectivity of the Na+-K+ pump for intracellular Na+. (3/383)Treatment of rabbits with angiotensin-converting enzyme (ACE) inhibitors increases the apparent affinity of the Na+-K+ pump for Na+. To explore the mechanism, we voltage clamped myocytes from control rabbits and rabbits treated with captopril with patch pipettes containing 10 mM Na+. When pipette solutions were K+ free, pump current (Ip) for myocytes from captopril-treated rabbits was nearly identical to that for myocytes from controls. However, treatment caused a significant increase in Ip measured with pipettes containing K+. A similar difference was observed when myocytes from rabbits treated with the ANG II receptor antagonist losartan and myocytes from controls were compared. Treatment-induced differences in Ip were eliminated by in vitro exposure to ANG II or phorbol 12-myristate 13-acetate or inclusion of the protein kinase C fragment composed of amino acids 530-558 in pipette solutions. Treatment with captopril had no effect on the voltage dependence of Ip. We conclude that ANG II regulates the pump's selectivity for intracellular Na+ at sites near the cytoplasmic surface. Protein kinase C is implicated in the messenger cascade. (+info)
Central lead administration inhibits water intake and sodium appetite in rats. (4/383)We have demonstrated that acute third ventricle injections of lead acetate (PbAc) exert a powerful antidipsogenic effect and induce a significant increase in renal sodium excretion. In the present study we confirm the antidipsogenic effect of lead and demonstrate that central administration of this metal, in minute amounts, significantly reduces salt intake both during dehydration and after central angiotensinergic stimulation. Adult male Wistar rats had the third ventricle cannulated seven days before the experiments. During this period they had free access to distilled water and hypertonic saline solution (1.5%). After a 24-h period of fluid deprivation, experimental animals received third ventricle injections of PbAc (0.3, N = 8 and 3.0 nmol/rat, N = 14) while controls received sodium acetate (NaAc; 3.0 nmol/rat, N = 10). Rats treated with PbAc at the highest dose showed a significant reduction (P<0.05) both in water and hypertonic saline intake when compared to controls. When the effect of lead administration on angiotensin II-induced water and salt intake was studied, normohydrated animals received third ventricle injections of angiotensin II (9.6 nmol/rat) after pretreatment with 3.0 nmol/rat of PbAc (experimental group, N = 10) or NaAc (controls, N = 8). The group pretreated with PbAc presented a significant reduction (P<0.05) in both water and salt intake compared to controls. Thus, this study confirms the antidipsogenic effect of central lead injections and demonstrates that the presence of lead in the brain exerts a significant inhibition of sodium appetite. (+info)
Self-protection by cardiac myocytes against hypoxia and hyperoxia. (5/383)Cardiac muscle must maintain a continuous balance between its energy supply and work performed. An important mechanism involved in achievement of this balance is cross talk via chemical signals between cardiac myocytes and the cardiac muscle vascular system. This has been demonstrated by incubating isolated cardiac myocytes in different concentrations of oxygen and then assaying the conditioned media for vasoactive substances on isolated aortic rings and small-resistance arteries. With increasing oxygen concentrations above 6%, cardiac myocytes produce increasing amounts of angiotensin I, which is converted to angiotensin II by the blood vessel. The angiotensin II stimulates vascular endothelial cells to secrete endothelin and increase vascular tone. Below 6% oxygen, cardiac myocytes secrete adenosine, which acts directly on vascular smooth muscle to block the effect of alpha-adrenergic agonists and reduce vascular tone. In an intact heart, the net effect of these 2 regulatory systems would be the maintenance of oxygen concentration within a narrow range at the cardiac myocytes. By acting as oxygen sensors, cardiac myocytes modulate vascular tone according to the needs of the myocytes and reduce potential problems of hypoxia and extensive formation of reactive oxygen species.

Regulated expression of human angiotensinogen gene by hepatocyte nuclear factor 4 and chicken ovalbumin upstream promoter-transcription factor. (6/383)We previously identified various upstream and downstream regulatory elements and factors important for hepatic expression of the human angiotensinogen (ANG) gene, the precursor of vasoactive octapeptide angiotensin II. In the present study, to further investigate the molecular mechanism of human ANG transcriptional regulation, we generated transgenic mice carrying the fusion gene composed of the 1. 3-kilobase promoter of the human ANG gene, its downstream enhancer, and the chloramphenicol acetyltransferase reporter gene. Because expression of the chloramphenicol acetyltransferase gene was observed strongly in the liver and weakly in the kidney, we suspected that hepatocyte nuclear factor (HNF) 4 with a tissue expression pattern similar to that of the reporter gene would regulate ANG transcription. In vitro assays indicated that HNF4 bound to the promoter elements and strongly activated the ANG transcription, but that chicken ovalbumin upstream promoter transcription factor (COUP-TF), a transcriptional repressor, dramatically repressed human ANG transcription through the promoter elements and the downstream enhancer core elements. Furthermore, COUP-TF dramatically decreased the human ANG transcription in the mouse liver by the Helios Gene Gun system in vivo. These results suggest that an interplay between HNF4 and COUP-TF could be important in hepatic human ANG transcription. (+info)
Evaluation of the angiotensin challenge methodology for assessing the pharmacodynamic profile of antihypertensive drugs acting on the renin-angiotensin system. (7/383)AIMS: The performance of the experimental paradigm of angiotensin challenges with continuous non-invasive blood pressure measurement was evaluated. Angiotensin dose-response relationships were characterized, along with the influence of clinical covariates. The stability of angiotensin-induced peaks and the variability of the angiotensin doses were assessed. Finally, the predictive value of studies based on angiotensin challenges to determine drug doses effective in therapeutics was evaluated. METHODS: The data were gathered from 13 clinical studies on nine angiotensin II receptor antagonists, one ACE inhibitor and one dual ACE-NEP inhibitor, using Finapres for measuring the response to exogenous angiotensin challenges. Modelling of angiotensin dose-response curves and determination of the inter and intrasubject variability were performed by nonlinear regression (NONMEM). The different sources of variations in angiotensin I and II doses and angiotensin-induced peaks were evaluated by analyses of variance. The dose of ACE inhibitors and angiotensin II receptor antagonists inhibiting blood pressure increase by at least 75%, as measured by this method, was chosen for comparison with the labelled starting dose. RESULTS: Angiotensin challenges exhibited a clear dose-response relationship which can be characterized both by an Emax or a log linear model. The log linear model gave an average systolic/diastolic response of 24+/-6/20+/-5 mmHg for a unit dose of 1 microgram of angiotensin II equivalents, and an increase of 6/6 mmHg for each doubling of the dose. The angiotensin ED50 calculated values were 0.67 microgram for systolic and 0.84 microgram for diastolic blood pressure. The angiotensin doses for eliciting a given response and the angiotensin induced peaks were fairly constant between period and subject, but vary significantly between studies. Based on an inhibition of blood pressure by 75%, the agreement was good between the doses of ACE inhibitors and angiotensin receptor antagonists predicted from studies using the methodology of angiotensin challenges and the doses shown to be clinically efficacious, in spite of high intersubject and intrasubject variabilities. CONCLUSIONS: This experimental method represents a valid surrogate for the therapeutic target and a useful tool for the pharmacokinetic and pharmacodynamic profiling of drugs acting on the renin-angiotensin system.

Angiotensin I-converting enzyme antisense gene therapy causes permanent antihypertensive effects in the SHR. (8/383)The renin-angiotensin system plays a critical role in the control of blood pressure (BP), and its hyperactivity is associated with the development and maintenance of hypertension. Although traditional pharmacological therapies targeted toward the inhibition of the renin-angiotensin system are effective in the control of this disease, they pose significant limitations. We used an antisense gene delivery strategy to circumvent these limitations and established that a single intracardiac administration of angiotensin type 1 receptor antisense (AT(1)R-AS) causes permanent prevention of hypertension in the spontaneously hypertensive rat (SHR), an animal model of primary human hypertension. Our objectives in this study were 2-fold: to determine (1) whether the targeting of angiotensin I-converting enzyme (ACE) mRNA by a similar antisense strategy would prevent the SHR from developing hypertension and (2) whether the antihypertensive phenotype is transmitted to the offspring from the antisense-treated parents. Administration of a retroviral vector containing ACE antisense (LNSV-ACE-AS) caused a modest yet significant attenuation of high BP ( approximately 15+/-2 mm Hg) exclusively in the SHR. This was associated with a complete prevention of cardiac and renovascular pathophysiological alterations that are characteristic of hypertension. Like their parents, the F(1) generation offspring of the LNSV-ACE-AS-treated SHR expressed lower BP, decreased cardiac hypertrophy, and normalization of renal arterial excitation-coupling compared with offspring derived from the LNSV-ACE-tS (truncated sense)-treated SHR. In addition, the endothelial dysfunction commonly observed in the SHR renal arterioles was significantly prevented in both parents and offspring of the LNSV-ACE-AS-treated SHR. Polymerase chain reaction followed by Southern analysis revealed that the ACE-AS was integrated into the SHR genome and transmitted to the offspring. These observations suggest that transmission of ACE-AS by retroviral vector may be responsible for the transference of normotensive phenotypes in the SHR offspring. (+info)
Metabolism of neuropeptides. Hydrolysis of the angiotensins, bradykinin, substance P and oxytocin by pig kidney microvillar...
Microvillar membranes derived from the brush border of the renal proximal tubule are very rich in peptidases. Pig kidney microvilli contain endopeptidase-24.11 associated with a battery of exopeptidases. The manner by which some neuropeptides are degraded by the combined attack of the peptidases of this membrane has been investigated. The contribution of individual peptidases was assessed by including inhibitors (phosphoramidon, captopril, amastatin and di-isopropyl fluorophosphate) with the membrane fraction when incubated with the peptides. Substance P, bradykinin and angiotensins I, II and III and insulin B-chain were rapidly hydrolysed by kidney microvilli. Oxytocin was hydrolysed much more slowly, but no products were detected from [Arg8]vasopressin or insulin under the conditions used for other peptides. The peptide bonds hydrolysed were identified and the contributions of the different peptidases were quantified. For each of the susceptible peptides, the main contribution came from ...

We characterized a unique mouse line in which the expression of AT1AR is deleted from TH-expressing cells. This deletion was verified by loss of AT1AR binding in sympathetic ganglia and adrenal medulla, as well as loss of a functional response to Ang II in the RVLM. At baseline, we observed no effect of this deletion. Subcutaneous infusion of a low dose of Ang II increased BP in both groups, but the increase was significantly delayed in onset (Discussion in the online-only Data Supplement) and reduced in magnitude in the CAT-KO mice. In WT mice, Ang II-dependent hypertension was associated with increased sympathetic activity as evidenced by increased power in the midfrequency band of the mean arterial pressure and HR spectra and activation of ROS production in key brain regions involved in the regulation of sympathetic activity. The CAT-KO mice have an attenuated sympathetic activation in response to Ang II and showed reduced ROS production in the RVLM. Overall, in Ang II-dependent hypertension, ...

Rat angiotensinogen is secreted only constitutively when transfected into AtT-20 cells. | Hypertension
To test whether angiotensinogen might be targeted to dense core secretory granules in cells containing a regulated secretory pathway, we expressed rat angiotensinogen in AtT-20 cells, a mouse pituitary cell line that has the demonstrated ability to correctly sort proteins to the constitutive or regulated pathway. We compared the pattern of secretion of angiotensinogen with that of endogenous adrenocorticotropin hormone, which is secreted by AtT-20 cells through the regulated pathway. When cells were incubated for 5 hours with dibutyryladenosine cyclic monophosphate or KCl, adrenocorticotropin hormone secretion was significantly higher than control, whereas monensin had no effect. In contrast, angiotensinogen secretion was markedly reduced by monensin, but no stimulation was observed with dibutyryladenosine cyclic monophosphate or KCl. These results make it unlikely that angiotensinogen could be cotargeted with active renin in the dense core granules of the regulated pathway. Alternative ...

Increased generation of reactive oxygen species (ROS) is a significant pathological feature in the brains of patients with Alzheimers disease (AD). Experimental evidence indicates that inhibition of brain ROS could be beneficial in slowing the neurodegenerative process triggered by amyloid-beta (Abeta) aggregates. The angiotensin II AT1 receptor is a significant source of brain ROS, and AD patients have an increased brain angiotensin-converting enzyme (ACE) level, which could account for an excessive angiotensin-dependent AT1-induced ROS generation. Therefore, we analyzed the impact of ACE inhibition on signs of neurodegeneration of aged Tg2576 mice as a transgenic animal model of AD. Whole genome microarray gene expression profiling and biochemical analyses demonstrated that the centrally active ACE inhibitor captopril normalized the excessive hippocampal ACE activity of AD mice. Concomitantly, the development of signs of neurodegeneration was retarded by six months of captopril treatment. The ...

This study investigated the impact of catalase (Cat) overexpression in renal proximal tubule cells (RPTCs) on nuclear factor erythroid 2Crelated factor 2 (Nrf2) stimulation of angiotensinogen (or gene promoter, were also studied. from the renin-angiotensin program (RAS) have always been implicated in the advancement and development of diabetic nephropathy. Nevertheless, the root molecular mechanisms stay incompletely understood. As well as the systemic RAS, the life of an area intrarenal RAS in renal proximal tubule cells (RPTCs) continues to be well noted (1). Many lines of proof indicate that improved era of reactive air species (ROS) is normally central towards the advancement of hypertension and RPTC apoptosis in diabetes. ROS mediate high-glucose (HG) arousal of angiotensinogen (Agt; the only real precursor of most angiotensins) gene appearance in RPTCs in vitro (2C5).

Neuropeptides : Metabolism to Bioactive Fragments and the Pharmacology of Their Receptors
The proteolytic processing of neuropeptides has an important regulatory function and the peptide fragments resulting from the enzymatic degradation often exert essential physiological roles. The proteolytic processing generates, not only biologically inactive fragments, but also bioactive fragments that modulate or even counteract the response of their parent peptides. Frequently, these peptide fragments interact with receptors that are not recognized by the parent peptides. This review discusses tachykinins, opioid peptides, angiotensins, bradykinins, and neuropeptide Y that are present in the central nervous system and their processing to bioactive degradation products. These well-known neuropeptide systems have been selected since they provide illustrative examples that proteolytic degradation of parent peptides can lead to bioactive metabolites with different biological activities as compared to their parent peptides. For example, substance P, dynorphin A, angiotensin I and II, bradykinin, ...

OPUS 4 | Search
The systemic renin-angiotensin system (RAS) is an endocrine system that is mainly known to regulate blood pressure, fluid and electrolyte balance as well as volume homeostasis in the body through different active metabolites, the angiotensin (Ang) peptides. In addition, local renin-angiotensin systems have been discovered in various tissues, including the islet of Langerhans. Starting with angiotensinogen, the precursor of all angiotensin peptides which is cleaved into the decapeptide Ang I by renin, the RAS is divided into three axes. The main classical RAS axis is composed of angiotensin converting enzyme (ACE), angiotensin (Ang) II, and the Ang II type 1 receptor (AT1R), whereas the two alternative RAS axes comprise either ACE2, Ang-(1-7) and the receptor Mas or the aminopeptidase N (APN), Ang IV and the insulin-regulated aminopeptidase (IRAP). The activation of the main ACE/Ang II/AT1R RAS axis has been associated with metabolic syndrome, type 2 diabetes mellitus, and islet dysfunction. The ...
A radiochemical renin assay | Biochemical Journal
1. A synthetic 3-([14C]valine)-labelled tetradecapeptide renin substrate was used to measure renin concentration. Renin liberated 14C-labelled angiotensin I, which was separated from the labelled substrate by paper chromatography. The conversion of substrate into angiotensin I was quantitated by liquid-scintillation counting of radioactivity. 2. The rate of conversion of the substrate into angiotensin I was shown to be linearly related to renin concentration and time under suitable conditions. Angiotensin generation measured in this system agrees well with that measured by bioassay. 3. It is suggested that the use of a pure substrate offers advantages that include the standardization of current units of renin measurement.. ...

BACKGROUND: The relationship between circulating levels of angiotensinogen and hypertension in the epidemiologic setting has not been studied much. Recent findings related to the association between hypertension and polymorphisms of the angiotensinogen gene have generated new interest in this potential pathway to hypertension. OBJECTIVES: To examine environmental factors associated with levels of circulating angiotensinogen as determinants of hypertension in populations of African origin. METHODS: We recruited 1557 participants from communities in Nigeria (n = 611), Zimbabwe (n = 161), Jamaica (n = 476), and Maywood, Illinois, USA (n = 309). RESULTS: Mean angiotensinogen levels varied widely across groups (Nigeria 1381 ng/ml angiotensin I generated, Zimbabwe 1638 ng/ml angiotensin and I generated Jamaica 1801 ng/ml angiotensin I generated, and Maywood 2039 ng/ml angiotensin I generated). Average body mass index was highly correlated to angiotensinogen level across the population samples, ...

ACE2-angiotensin-(1-7)-Mas axis in renal ischaemia/reperfusion injury in rats
AngII (angiotensin II), ACE (angiotensin I-converting enzyme) and the AT(1) receptor (AngII type I receptor) are associated with the inflammatory process and microvascular dysfunction of AKI (acute kidney injury) induced by renal I/R (ischaemia/reperfusion). However, Ang-(1-7) [angiotensin-(1-7)], ACE2 (angiotensin I-converting enzyme 2) and the Mas receptor also play a role in renal disease models. Therefore, in the present study, we have examined the renal profile of Ang-(1-7), ACE2 and the Mas receptor in renal I/R and compared them with that of AngII, ACE and the AT(1) receptor. Male Wistar rats were submitted to left nephrectomy and ischaemia (45 min) followed by reperfusion (2 or 4 h) in the right kidney. At 4 h of reperfusion, renal AngII was increased (P , 0.01) and renal Ang-(1-7) was decreased substantially (P , 0.05), although plasma levels of both angiotensins were unchanged. in addition, renal I/R decreased the renal mRNA expression of renin (P , 0.05), AT(1) receptors (P , 0.001) ...

Renin Angiotensin System Gene Polymorphisms and Cerebral Blood Flow Regulation | Stroke
This study provides preliminary evidence that a polymorphism in the AGT gene is independently associated with cerebral VR in white elderly persons. Homozygous carriers of the CC genotype of the rs699 SNPs have lower cerebral CO2 VR compared with the other genotypes.. To our knowledge, this is the first study to provide evidence that renin angiotensin system genes are also involved in cerebral VR. Previous evidence suggests a genetic role of this system in brain health and diseases such as stroke, depression, and cognitive impairment.26,27 This study adds evidence that this system may also be involved in VR, which is linked with aging outcomes such as stroke2 and dementia.28. CO2-dependent VR is mediated in part by the endothelium and is related to changes in nitric oxide.29,30 Changes in end-tidal CO2 are associated with fast changes in pH, which modulate the effect of nitric oxide synthase leading to changes in nitric oxide production.31 In addition, ATP-dependent K+ channel activation may ...

These peptides have been around since the eighties. Thymopentin was one of the most well-known peptides in this class, and it was used to prevent HIV infections. It was discontinued because of the reimbursement policies offered by insurance companies. Other thymic hormones, like alpha-1 and thymosin, are still in use in the Middle East, Southern Asia, and South America.. Other synthetic peptides, like oxytocins, ACTH (124), and angiotensins, have been here for a longer time and they are being still used and produced. There is no doubt about the fact that the market for synthetic peptides.

New Aspects of the Renin Angiotensin System in Cardiovascular and Renal Diseases:: volume 1 | Bentham Science
Cancer is a broad group of diseases involving unregulated cell growth with elevated death rates as more people live in old age with mass lifestyle changes occurring in the world. The causes of cancer are diverse, complex, and still only partially understood. The chances of surviving the disease vary remarkably by the type and location of the malignancy and the extent of disease at the start of treatment. Early cancer detection is proving to be a valid approach. Cancer can be detected in a number of ways, including the presence of certain signs and symptoms, screening tests, or medical imaging. Cancer therapy is dynamically changing and revision and change in patient management is constant as our knowledge increases. Cancer is routinely treated with chemotherapy, radiation therapy and surgery. Tailored cancer targeted therapy is becoming an emerging objective of today. In this book, a constructive group of cancer research experts bring the reader their shared vision, to give an extensive and ...
