Abstract
The renin-angiotensin system (RAS) is an important cascade of enzymes and peptides that regulates blood pressure, volume, and electrolytes. Within this complex system of reactions, its counter-regulatory axis has attracted attention, which has been associated with the pathophysiology of inflammatory and fibrotic diseases. This review article analyzes the impact of different components of the counter-regulatory axis of the RAS on different pathologies. Of these peptides, Angiotensin-(1-7), angiotensin-(1-9) and alamandine have been evaluated in a wide variety of in vitro and in vivo studies, where not only they counteract the actions of the classical axis, but also exhibit independent anti-inflammatory and fibrotic actions when binding to specific receptors, mainly in heart, kidney, and lung. Other functional peptides are also addressed, which despite no reports associated with inflammation and fibrosis to date were found, they could represent a potential target of study. Furthermore, the association of agonists of the counter-regulatory axis is analyzed, highlighting their contribution to the modulation of the inflammatory response counteracting the development of fibrotic events. This article shows an overview of the importance of the RAS in the resolution of inflammatory and fibrotic diseases, offering an understanding of the individual components as potential treatments.

Abstract
Food-derived peptides with antihypertensive properties have received great interest during the past 30 years. There is solid evidence of the effect of various peptide sequences in clinical trials, but their use in preventive or therapeutic treatments is not extensive. There are certain issues, such as the bioavailability or the mechanism of action, that would need to be clarified to establish a direct cause/effect relationship between the administered molecule and the observed effect. This perspective emphasizes the advances in the study of antihypertensive peptides and proposes future research topics that might encourage industry and health policy to exploit these food constituents.

Abstract
Fermentation of soybean is a process in which soy proteins are broken down into small peptides to exert various physiological functions beyond their nutritional value and to improve food source bioactive components responsible for health benefits. Enzymatic hydrolysis could speed up the degradation of proteins during fermentation of soybean, thus resulting in higher peptide production. In the present study, fermented soy meal (fermented with Bacillus subtilis from Douchi) was hydrolyzed by thermolysin, and the water extraction was then separated into four fractions using ultrafiltration membranes. Their vasorelaxation activities were screened, and the most potent fraction was further isolated and purified to obtain four peptides. Briefly, three peptides exerted a dose-dependent vasorelaxation (0.01-4.10 μM) in the phenylephrine preconstricted thoracic aorta ring of Sprague-Dawley rat (relaxation actions were all endothelium-independent), while one peptide induced vasoconstriction. Furthermore, an independent causal relationship between vasorelaxation and angiotensin converting enzyme (ACE) inhibition activities was found.

Abstract
Angiotensin-(3−4) (Ang-(3−4) or Val-Tyr) is the shorter angiotensin (Ang) II-derived peptide, formed through successive hydrolysis that culminates with the release of Val-Tyr as a dipeptide. It is formed both in plasma and in kidney from Ang II and Ang III, and can be considered a component of the systemic and organ-based renin–angiotensin system. It is potently antihypertensive in humans and rats, and its concerted actions on proximal tubule cells culminate in the inhibition of fluid reabsorption, hyperosmotic urinary excretion of Na+. At the renal cell signaling level, Ang-(3−4) counteracts Ang II-type 1 receptor-mediated responses by acting as an allosteric enhancer in Ang II-type 2 receptor populations that target adenosine triphosphate-dependent Ca2+ and Na+ transporters through a cyclic adenosine monophosphate-activated protein kinase pathway.

Abstract
Our previous studies have shown that Coix glutelin pepsin hydrolysate can effectively inhibit angiotensin converting enzyme (ACE) activity in vitro. The main purpose of this study was to obtain potent anti-hypertensive peptides from Coix glutelin. The Coix glutelin hydrolysates (CGH) were prepared by pepsin catalysis and further separated by an ultrafitration (UF) system, gel filtration chromatography (GFC) and reversed-phase high performance liquid chromatography (RP-HPLC). As a result, the sub-fraction F5-3 had the highest ACE-inhibitory activity. Six ACE inhibitory peptides were identifiedusing nano-liquid chromatography coupled to tandem mass spectrometry. The most potent peptide GAAGGAF (IC50 = 14.19 μmol·L-1) was finally obtained by further molecular simulation screening and a series of division and optimization. Single oral administration of synthesized GAAGGAF at 15 mg/kg body weight (BW) in spontaneously hypertensively rats (SHR) could reduce the systolic blood pressure (SBP) around 27.50 mmHg and blood pressure-lowering effect lasted for at least 8 h. The study demonstrated for the first time that the ACE inhibitory peptide GAAGGAF from Coix glutelin has a significant antihypertensive effect, and it could be a good natural ingredient for pharmaceuticals against hypertension and the related diseases.

Abstract
The renin angiotensin system (RAS) is a key mediator of blood pressure regulation. Angiotensin II (Ang II), the active component of RAS, is a potent vasoconstrictor that also causes abnormal proliferation, oxidative stress, and inflammation in vascular smooth muscle cells (VSMCs) that contribute to atherosclerotic changes. Egg white ovotransferrin-derived tripeptide IRW (Ile-Arg-Trp) was previously shown to exert antihypertensive effect by reducing Ang II synthesis as well as endothelial cell inflammation and endothelial dysfunction. However, the effects of IRW on VSMCs are still unclear. In the present study, we evaluated the antiproliferative, antioxidant, and anti-inflammatory effects of IRW on VSMCs in the presence of Ang II stimulation. It was found that IRW treatment could attenuate Ang II-stimulated proliferation, superoxide production, and inflammation in VSMCs. These beneficial effects appeared to involve modulation of the NF-κB pathway. These findings could further our understanding on the antihypertensive mechanism of IRW beyond vascular endothelium.

Abstract
The antihypertensive effect of the bovine casein-derived peptide Met-Lys-Pro (MKP) was examined in vitro and in vivo. MKP showed angiotensin I-converting enzyme (ACE)-inhibitory activity in vitro (IC50 = 0.43 μM). An in vivo kinetics study using radiolabeled Met-[1-(14)C]Lys-Pro ((14)C-MKP) showed that orally administered (14)C-MKP to spontaneously hypertensive rats (SHRs) was absorbed and moved into the plasma. In vitro vasoconstriction of thoracic aorta preparations, which was induced by adding angiotensin I, was reduced by prior exposure of MKP. A single oral dose of MKP lowered systolic blood pressure (SBP) of SHRs, and repeated oral administration of MKP for 28 days significantly lowered SBP of SHRs. The results obtained in the present study suggest that orally administrated MKP can be absorbed into the plasma and its ACE-inhibitory activity may contribute to induce the antihypertensive effect in vivo.

Abstract
The physiological roles of ANG-(3-4) (Val-Tyr), a potent ANG II-derived peptide, remain largely unknown. The present study 1)investigates whether ANG-(3-4) modulates ouabain-resistant Na(+)-ATPase resident in proximal tubule cells and 2) verifies whether its possible action on pumping activity, considered the fine tuner of Na(+) reabsorption in this nephron segment, depends on blood pressure. ANG-(3-4) inhibited Na(+)-ATPase activity in membranes of spontaneously hypertensive rats (SHR) at nanomolar concentrations, with no effect in Wistar-Kyoto (WKY) rats or on Na(+)-K(+)-ATPase. PD123319 (10(-7) M) and PKA(5-24) (10(-6) M), an AT2 receptor (AT2R) antagonist and a specific PKA inhibitor, respectively, abrogated this inhibition, indicating that AT2R and PKA are central in this pathway. Despite the lack of effect of ANG-(3-4) when assayed alone in WKY rats, the peptide (10(-8) M) completely blocked stimulation of Na(+)-ATPase induced by 10(-10) M ANG II in normotensive rats through a mechanism that also involves AT2R and PKA. Tubular membranes from WKY rats had higher levels of AT2R/AT1R heterodimers, which remain associated in 10(-10) M ANG II and dissociate to a very low dimerization state upon addition of 10(-8) M ANG-(3-4). This lower level of heterodimers was that found in SHR, and heterodimers did not dissociate when the same concentration of ANG-(3-4) was present. Oral administration of ANG-(3-4) (50 mg/kg body mass) increased urinary Na(+) concentration and urinary Na(+) excretion with a simultaneous decrease in systolic arterial pressure in SHR, but not in WKY rats. Thus the influence of ANG-(3-4) on Na(+) transport and its hypotensive action depend on receptor association and on blood pressure.

Abstract
Prevention and management of hypertension are the major public health challenges worldwide. Uncontrolled high blood pressure may lead to a shortened life expectancy and a higher morbidity due to a high risk of cardiovascular complications such as coronary heart disease (which leads to heart attack) and stroke, congestive heart failure, heart rhythm irregularities, and kidney failure etc. In recent years, it has been recognized that many dietary constituents may contribute to human cardiovascular health. There has been an increased focus on identifying these natural components of foods, describing their physiological activities and mechanisms of actions. Grain, vegetables, fruits, milk, cheese, meat, chicken, egg, fish, soybean, tea, wine, mushrooms, and lactic acid bacteria are various food sources with potential antihypertensive effects. Their main bioactive constituents include angiotensin I-converting enzyme (ACE) inhibitory peptides, vitamins C and E, flavonoids, flavanols, cathecins, anthocyanins, phenolic acids, polyphenols, tannins, resveratrol, polysaccharides, fiber, saponin, sterols, as well as K, Ca, and P. They may reduce blood pressure by different mechanisms, such as ACE inhibition effect, antioxidant, vasodilatory, opiate-like, Ca(2+) channel blocking, and chymase inhibitory activities. These functional foods may provide new therapeutic applications for hypertension prevention and treatment, and contribute to a healthy cardiovascular population. The present review summarizes the antihypertensive food sources and their bioactive constituents, as well as physiological mechanisms of dietary products, especially focusing on ACE inhibitory activity.

Abstract
Apple procyanidins (AP), one of the polyphenol-rich compounds, showed an endothelial-dependent vasorelaxation in rat aorta, but the mechanisms of beneficial effects are still unclear. The present study was designed to clarify the potential role of AP in rat aorta endothelial cells (RAECs). The treatment of RAECs with AP (1-10 μg/ml) resulted in a dose-dependent hyperpolarization with a maximum effect at 10 μg/ml, and for this reason, AP (10 μg/ml) was used in all the following experiments. AP-induced hyperpolarization was significantly inhibited by pretreatment of nonspecific K(+) inhibitor, tetraethyl ammonium chloride or specific K(+) channel inhibitors, iberiotoxin, glibenclamide, 4-aminopyridine and BaCl(2), as well as by high KCl or Ca(2+)-free solution. AP-induced hyperpolarization was also proved using 64-channel multielectrode dish system that can monitor a direct and real-time change of membrane potential. Furthermore, AP treatment caused a significant increase of nitric oxide (NO) production and cyclic guanosine monophosphate levels via endothelial NO synthase messenger RNA expression. The NO production was inhibited by N(G)-monoethyl-l-arginine or Ca(2+)-free solution and was completely abolished by their combination. Also, AP inhibited endothelial proliferation, while the effect was significantly abolished by N(G)-monoethyl-l-arginine or tetraethyl ammonium chloride. These findings suggest that AP induces both hyperpolarization of RAECs via multiple activation of K(+) channels and activation of NO/cyclic guanosine monophosphate pathway via increasing NO production or is responsible for antiangiogenic effect. Diminishment of hyperpolarization as well as NO production of AP in Ca(2+)-free solution implicated that AP would play a crucial role in promoting Ca(2+) influx into endothelial cells so as to promote both actions.

Application of 13C stable isotope labeling liquid chromatography-multiple reaction monitoring-tandem mass spectrometry method for determining intact absorption of bioactive dipeptides in rats. Anal Biochem 2011; 414:109-16. [PMID: 21377441 DOI: 10.1016/j.ab.2011.02.037] [Citation(s) in RCA: 35] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2010] [Revised: 02/21/2011] [Accepted: 02/24/2011] [Indexed: 11/22/2022]
Abstract
The liquid chromatography-multiple reaction monitoring-tandem mass spectrometry (LC-MRM-MS/MS) method using (13)C stable isotope-labeled dipeptides was newly developed to simultaneously determine the absorption of three antihypertensive peptides (Val-Tyr, Met-Tyr, and Leu-Tyr) into blood of spontaneously hypertensive rats in one run-in assay. After extracting (13)C-labeled peptides in blood sample with a C(18) cartridge, the extract was applied to a (13)C monoisotopic transition LC-MRM-MS/MS system with D-Val-Tyr included as internal standard. An excellent separation of each dipeptide in LC was achieved at the elution condition of 5-100% methanol in 0.1% formic acid at a flow rate of 0.25 ml/min. The (13)C-labeled peptides ionized by electron spray were detected in the positive ion mode within 15 min. The established method showed high reproducibility with less than 10% coefficient of variation as well as high accuracy of more than 85%. After the administration of a mixture containing the three (13)C-labeled dipeptides to rats at each dose of 30 mg/kg, we could successfully determine the intact absorption of each (13)C-labeled peptide with the maximal absorption amount of 1.1 ng/ml plasma for Val-Tyr by the proposed LC-MRM-MS/MS method.

Milk casein-derived tripeptides, VPP and IPP induced NO production in cultured endothelial cells and endothelium-dependent relaxation of isolated aortic rings. Heart Vessels 2011; 26:549-56.

Abstract
Milk casein-derived tripeptides, valyl prolyl proline (VPP), and isoleucyl prolyl proline (IPP) inhibit angiotensin-converting enzyme (ACE) and both fermented milk and proteolytic hydrolysates of milk casein containing these peptides exert blood pressure-lowering effects in animals and humans. On the top of these results, we have recently reported that the hydrolysate of milk casein containing both VPP and IPP improved the vascular endothelial function of subjects with stage I hypertension, enforcing us to elucidate the mechanism of the improvement of endothelial dysfunction by these peptides. For this purpose, we examined the effect of VPP and IPP on induction of nitric oxide (NO) production using cultured vascular endothelial cells and isolated arterial vessels. When both VPP and IPP were added to the medium of cultured endothelial cells at final concentrations of more than 100 nmol/l, the NO(x) (NO(2) and NO(3)) concentration in the medium was significantly higher than that of the control. Moreover, both VPP and IPP induced endothelium-dependent relaxation of isolated aortic rings, and these effects were inhibited by NO synthase inhibitors, K channel inhibitors, and bradykinin B2 receptor antagonists. These lines of results suggested that both VPP and IPP induced production of vasodilative substances including NO.

Abstract
Our previous findings regarding the biological activities of small peptides revealed that a di-peptide, Trp-His (WH), could play a role in the prevention of vascular lesions, including cell proliferation and atherosclerosis. Its vasoprotective effects could be associated with suppression of the vasocontraction signaling cascade, but the underlying mechanism(s) remains obscure. In this study, we attempted to elucidate the vasoprotective mechanism of WH, in opposing the proliferation of rat vascular smooth muscle cells (VSMCs). In VSMCs from 8 week-old male Wistar rat thoracic aortae, WH evoked a significant dose-dependent anti-proliferation effect, without cytotoxicity. In mitogen-stimulated cell experiments, 300 μM WH inhibited cytosolic Ca(2+) elevation in VSMCs induced by 10 μM angiotensin II (Ang II). Furthermore, WH suppressed extracellular Ca(2+) entry into CaCl(2)-stimulated VSMCs. The biological capacity of WH as an intracellular Ca(2+) ([Ca(2+)](i)) suppressor was also proven when 50 μM Bay K8644 was used to enhance Ca(2+) entry via a voltage-dependent l-type Ca(2+) channel (VDCC) and 300 μM WH elicited a 23% reduction in [Ca(2+)](i). The absence of a reduction of the [Ca(2+)](i) by the mixture of tryptophan and histidine revealed the importance of the peptide backbone in the [Ca(2+)](i) reduction effect. Furthermore, the WH-induced [Ca(2+)](i) reduction was abolished by verapamil, but not by nifedipine, indicating that WH likely binds to an extracellular site of the VDCC at a site similar to that of the dihydropyridine type-Ca(2+) channel blockers.

Abstract
AIM A food-derived bioactive tripeptide, Val-Pro-Pro (VPP), has been shown to possess angiotensin I-converting enzyme (ACE) inhibitory activity and foods containing such peptides exhibit an anti-hypertensive effect in clinical settings. METHODS The present study focused on the effect of VPP on monocyte adhesion to endothelium under flow conditions using phorbol 12-myristate 13-acetate (PMA)-stimulated monocytic THP-1 cells. RESULTS Pre-incubation of THP-1 cells with VPP (1 mM, 24 hours) significantly decreased the PMA-induced adhesion of THP-1 cells (p<0.05) to human umbilical vein endothelial cells (HUVECs). PMA-induced up-regulation of beta1 and beta2 integrin activation in THP-1 cells was downregulated by VPP, which significantly suppressed only the PMA-induced phosphorylation of JNK (p<0.05) in THP-1 cells. In addition, preincubation of THP-1 with SP600125, a specific inhibitor of JNK, resulted in significant reduction of the PMA-induced adhesion of THP-1. Interestingly, another tripeptide with comparable ACE inhibitory activity, Leu-Gly-Pro (LGP), failed to reduce the PMA-induced adhesion of THP-1, suggesting a distinct anti-inflammatory effect of VPP on THP-1 adhesion. CONCLUSION These observations suggest that VPP moderates monocyte adhesion to inflamed endothelia via attenuation of the JNK pathway in monocytes, which might contribute to the primary prevention of atherosclerosis.

Abstract
AIM The chemokine fractalikine is expressed in vascular endothelium, exerting a pro-atherogenic effect. Two single-nucleotide polymorphisms of the CX3CR1 gene (T280M and V249I) affect frac-talkine receptor expression and function. We aimed to assess the prevalence of CX3CR1 polymor-phisms and the association with ischemic cerebrovascular attacks in a cohort of carotid atheromatous disease patients and age-matched controls. METHODS Using PCR-RFLP, we analyzed allelotypes for T280M and V249I in 150 patients with and 151 controls without carotid atherosclerosis assessed using carotid duplex ultrasound; the subjects were patients admitted for any reason to a tertiary hospital. Genotype data were compared with modifiable risk factors for cerebrovascular disease and the reason for admission, using ischemic stroke as an endpoint. Stroke types associated with carotid atherosclerosis were analysed separately. RESULTS The M280 allelic frequency was lower among carotid atherosclerosis patients than controls (0.15 versus 0.23, adjusted OR 0.47, 95% CI 0.30-0.74). Absence of M280 allele was an indepen-dent factor associated with carotid atherosclerosis (OR 3.70, 95% CI 1.92-7.14), stronger than hypertension, dyslipidemia, diabetes and cigarette smoking. The I249 allele was also under-repre-sented in carotid atherosclerosis; this was not statistically significant. T280M and V249I genotypes were not associated with admission due to ischemic stroke of the large vessel subtype (TOAST classi-fication, 73 episodes), whereas carotid atherosclerosis, previous ischemic event, age, hypertension, diabetes, hyperlipidemia and cigarette smoking were all independently associated. CONCLUSIONS The M280 fractalkine receptor gene allele is associated with a lower risk of carotid ath-eromatous disease, independent from the modifiable cerebrovascular risk factors.

Abstract
Most of the investigations for an alternative medicinal treatment on atherosclerosis have been focused on natural or dietary compounds including phytochemicals. So far, few studies regarding anti-atherosclerotic small peptides except for tetrapeptide of Lys-Arg-Glu-Ser have been reported. The present study was, thus, to investigate whether dipeptide Trp-His, which is one of vasodilating small peptides, could reduce atherosclerotic lesions in apo E-deficient mice fed a high-fat diet. The animal study involved a 9-week-successive administration of Trp-His at a dose of 0, 10 or 100 mg/kg per d. After 9-week administration, en face analyses provided the first direct evidence that the atherosclerotic lesion area was significantly reduced by 27 and 38 % for Trp-His dosed at 10 and 100 mg/kg per d, respectively, compared with the control group. Administration of Trp-His did not affect growth parameters such as body weight and feeding efficiency (P>0·1). Total serum cholesterol and HDL-cholesterol as well as lipid profiles in the liver did not differ between the tested groups. Taken together, the anti-atherosclerotic effect of dipeptide Trp-His should be addressed into physiological functions of bioactive peptides, in which the dipeptide may elicit the power by alternative mechanism(s), not by the regulation of lipid metabolism.

Abstract
In a previous paper we demonstrated that Ang-(3-4) counteracts inhibition of the Ca(2+)-ATPase by Ang II in the basolateral membranes of kidney proximal tubules cells (BLM). We have now investigated the enzymatic routs by which Ang II is converted to Ang-(3-4). Membrane-bound angiotensin converting enzyme, aminopeptidases and neprilysin were identified using fluorescent substrates. HPLC showed that Plummer's inhibitor but not Z-pro-prolinal blocks Ang II metabolism, suggesting that carboxypeptidase N catalyzes the conversion Ang II--> Ang-(1-7). Different combinations of bestatin, thiorphan, Plummer's inhibitor, Ang II and Ang-(1-5), and use of short proteolysis times, indicate that Ang-(1-7)--> Ang-(1-5)--> Ang-(1-4)--> Ang-(3-4) is a major route. When Ang III was combined with the same inhibitors, the following pathway was demonstrated: Ang III--> Ang IV--> Ang-(3-4). Ca(2+)-ATPase assays with different Ang II concentrations and different peptidase inhibitors confirm the existence of these pathways in BLM and show that a prolyl-carboxypeptidase may be an alternative catalyst for converting Ang II to Ang-(1-7). Overall, we demonstrated that BLM have all the peptidase machinery required to produce Ang-(3-4) in the vicinity of the Ca(2+)-ATPase, enabling a local RAS axis to effect rapid modulation of active Ca(2+) fluxes.

Abstract
In the present study, we primarily attempted to identify di- and tri-peptides showing potent vasodilation in 1.0 microM phenylephrine-contracted thoracic aortas of Sprague-Dawley rats. Synthetic 15 Trp-His (WH) skeleton analogues were used for rat aorta ring's force measurements, since WH was found to be a vasoactive di-peptide so far. Among the synthesized peptides consisted of both His and Trp amino acid residues, His-Arg-Trp (HRW) was found to evoke the most potent vasodilation with an EC50 value of 1.2+/-0.08 mM in an endothelium-independent manner, while no effect was evoked by a mixture of individual amino acids. In addition to the structure of tri-peptides-activity relationship, chemically modified HRW analogues, i.e., 1- or 3-methyl-His-Arg-Trp and His-citrulline-Trp demonstrated the structural importance of tri-peptide to evoke the vasoactivity as following factors: (1) Neutral imidazole and indole groups from His and Trp residues at N- and C-terminals, respectively and (2) basic amino acids at the middle position. In mitogen (10 microM angiotensin II or 50 microM Bay K8644)-stimulated vascular smooth muscle cells, vasoactive HRW (100 microM) caused significant [Ca(2+)](i) reduction to an extent of >30%. Thus, our results suggest that HRW caused vasodilation action via an endothelium-independent mechanism which probably involves the suppression of extracellular Ca2+ influx through voltage-gated l-type Ca2+ channel.

Abstract
Proliferation of vascular smooth muscle (VSM) cells is a crucial step for developing vascular diseases such as atherosclerosis, hypertension and vascular restenosis after angioplasty. Proliferation of VSM cells is regulated by many intracellular signals: second messengers (e.g. Ca(2+), phosphatydylinositol, cAMP/cGMP), protein kinases and transcription factors. Although Ca(2+) regulation of cell proliferation is very important, there is rarely any informative review paper about the topic. Increase in cytosolic intracellular Ca(2+) concentration ([Ca(2+)](i)) due to Ca(2+) entry is necessary for proliferation of VSM cells. Elevation of [Ca(2+)](i) is needed for both cell cycle progressions at G(1)/S phase and the cell division in M phase. Intracellular Ca(2+) is regulated by the balance between Ca(2+)-elevating machinery such as Ca(2+) influx through voltage-dependent Ca(2+) channels (VDCC), Ca(2+) release from stored Ca(2+) in sarcoplasmic reticulum and Ca(2+)-lowering machinery such as Ca(2+) transport ATPases. In this review paper, we focus on the role of VDCC in the regulation of cell proliferation, especially in VSM cells. We also described significant roles of VDCC in pathophysiological conditions such as atherosclerosis, stroke and renal dysfunction.

Abstract
We previously demonstrated that Ang II inhibits the renal plasma membrane Ca(2+)-ATPase. In the present work we have studied the effect of Ang II, at concentrations similar to those found in the renal interstitium, on the Ca(2+)-ATPase from proximal tubule cells. High Ang II concentration (5 x 10(-7) mol/L) led to the recovery of Ca(2+)-ATPase activity previously inhibited by 50% at low Ang II concentration (10(-10) mol/L). Reactivation occurred in parallel with: (i) formation of only two dead-end metabolites [Ang-(3-4) and Tyr] after incubation of isolated membranes with micromolar Ang II; and (ii) dissociation of constitutive AT(1)R/AT(2)R heterodimers, which are preserved with 10(-10) mol/L Ang II. When the membranes were incubated with 10(-14) mol/L Ang-(3-4), inhibition by 10(-10) mol/L Ang II was no longer observed. The counteracting effect of Ang-(3-4) was abolished by PD123319, an antagonist of AT(2)R, and mimicked by CGP42112A, an agonist of AT(2)R. Ang-(1-7) is an intermediate in the formation of Ang-(3-4) via a pathway involving angiotensin-converting enzyme (ACE), and complete dipeptide breakdown to Tyr and Val is impaired by low Ang II. We conclude that Ang-(3-4) may be a physiological regulator of active Ca(2+) fluxes in renal proximal cells by acting within the renin-angiotensin axis.

Abstract
We have measured the expression of T-type Ca2+ channel mRNA in breast cancer cell lines (MCF-7 (ERalpha+) using Western blot and quantitative real-time PCR (Q-RT-PCR). These results revealed that the MCF-7 cells express both alpha1G and alpha1H isoforms of T-type Ca2+ channels. In order to further clarify the role of T-type Ca2+ channels in proliferation, we tested the effects of a selective T-type Ca2+ channel inhibitor NNC-55-0396 on cellular proliferation. MCF-7 (ERalpha+) cellular proliferation was inhibited by the compound. In contrast, NNC-55-0396 at same concentration had no effect on the proliferation of MCF-10A cells, a non-cancer breast epithelial cell line. We also found that message expression of the T-type Ca2+ channels were only expressed in rapidly growing non-confluent cells but not in the cytostatic confluent cells. Knocking down the expression of T-type Ca2+ channels with siRNA targeting both alpha1G and alpha1H resulted in growth inhibition as much as 45%+/-5.0 in MCF-7 cells as compared to controls. In conclusion, our results suggest that T-type Ca2+ channel antagonism/silencing may reduce cellular proliferation in mitogenic breast cells.

These peptides are known to be angiotensin converting enzyme (ACE) inhibitors in vitro, but the actual antihypertensive mechanisms in vivo are still unclear. In this research, we used rat aortic rings in organ bath experiments to investigate five potential vascular antihypertensive mechanisms of the dipeptide Val-Tyr. Only one significant effect was observed, namely preincubation of the aorta with Val-Tyr led to a significant shift of the concentration-response curve evoked by angiotensin I (Ang I). Val-Tyr had no effect on the angiotensin II receptor or the alpha-adrenergic receptor. Furthermore, it did not interact with voltage-operated Ca2+ channels, or with nitric oxide production/availability. In conclusion, our results show that Val-Tyr specifically inhibits Ang I-evoked contraction through ACE inhibition and that four other main mechanisms of vascular tone regulation are not affected.
