Abstract:
During the past thirty years, investigators of the renin-angiotensin system have found renin-like substances in a number of non-traditional locations throughout mammalian systems. These renin-like substances have been found in virtually every component of the brain, as well as the salivary glands, adrenal glands, blood vessels, genital tracts of both males and females, tumor cell lines, and even the eyeball and retina. This thesis is a literary review which will focus on extrarenal renin sources located in the uterus and the testis. These two locations are of particular interest because of the probable function in the regulation of the reproductive cycle. In addition, information on submaxillary gland renin and brain renin will also be discussed but to a lesser extent than uterine and Leydig Cell renin. Extrarenal renin sources have been tagged as renin-like enzymes, or more popularly as isorenins, because immunologically they react as true renin does. The immunoreactivity of these isorenins has been detected by a number of methods which include immunohistochemistry, specific staining characteristics of immunolabelling, native gel electrophoresis, sodium dodecyl sulfate gel electrophoresis, isoelectric focusing, double immunodiffusion, and symmetric chromatographic elution patterns. Extensive research in this area is still underway. Numerous modes of detection are being used to evaluate the specific sites of synthesis for these extrarenal renin sources, as well as their release mechanisms and physiological roles. Undoubtedly, the data resulting from these investigations will reveal significant information regarding these non-traditional renin sources and their clinical relevance in the treatment of hypertension.

Sas, Hatice Sinem. "Modeling Of Particle Filled Resin Impregnation In Compression Resin Transfer Molding." Master's thesis, METU, 2010. http://etd.lib.metu.edu.tr/upload/12612158/index.pdf.

Full text
Abstract:
Compression Resin Transfer Molding (CRTM) is an advanced liquid molding process for producing continuous fiber-reinforced composite parts in relatively large dimensions and with high fiber volume fractions. This thesis investigates this process for the purpose of producing continuous fiber reinforced composites with particle fillers. In many composites, fillers are used within the resin for various reasons such as cost reduction and improvement of properties. However, the presence of fillers in a process involving resin impregnation through a fibrous medium can result in a composite with non-homogeneous microstructure and properties. This work aims to model the resin impregnation and particle filtration during injection and compression stages of the process. For this purpose, a previously developed particle filtration model is adapted to CRTM. An appropriate commercial software tool is used for numerical solution after a survey of available packages. The process is analyzed based on the developed model for various process scenarios. The results of this study aim to enhance the understanding of particle-filled resin impregnation and particle filtration phenomena in the CRTM process and are likely to be used towards designing optimum process configurations for a desired outcome in the future.

He, Shaoda. "Helical reconstruction in RELION." Thesis, University of Cambridge, 2018. https://www.repository.cam.ac.uk/handle/1810/284086.

Full text
Abstract:
Helical assemblies of proteins are ubiquitous in nature and they perform vital functions in a wide range of organisms. The recent development of direct electron detectors and other imaging techniques in cryo-electron microscopy (cryo-EM) has opened new possibilities in solving helical structures at atomic resolution. Existing software packages for helical processing often require experience in tuning many ad hoc parameters to achieve optimal reconstruction results. REgularised LIkelihood OptimisatioN (RELION), an open-source single-particle analysis package, reduces the need for user expertise by the formulation of an empirical Bayesian framework, and has yielded some of the highest resolution density maps in recent years. Prior information about the helical assemblies can be conveniently incorporated into the statistical framework of RELION and thereby improves the helical reconstructions. This PhD thesis describes the development of a helical processing computation workflow with reduced user intervention in RELION. Chapter 1 introduces the theoretical basis of cryo-EM data acquisition and single-particle data processing, the concepts of helical symmetry, and a previously described method for iterative real-space reconstruction of helical assemblies, to which the RELION implementation bears resemblance. Chapter 2 discusses multiple adaptations to RELION that are necessary for helical processing. Key elements include the imposition and local refinement of helical symmetry, masks on helical segments and references, expressions of angular and translational prior information, manual and automated segment picking as well as initial model generation for helices. Calculations have been performed on four test data sets showing that the developed methods in RELION yield results that are as good as or better than alternative approaches for the tests performed. Chapter 3 describes the same methodology adapted to helical sub-tomogram averaging in RELION. Chapter 4 introduces the local symmetry option developed for special types of filaments with pseudo-helical symmetry. The concept can be extended to general single-particle analysis as well. Chapter 5 describes four helical structures determined in collaboration with other research groups using helical RELION for data processing. Chapter 6 concludes the thesis with a brief summary and future prospects.

Full text
Abstract:
Resin infusion of composite parts has continually been reaching to achieve laminate quality equal to, or exceeding, the quality produced with prepreg in an autoclave. In order for this to occur, developers must understand the key process variables that go in to producing a laminate with minimal void content. The purpose of this research is to continue efforts in understanding 1) the effect of process conditions on the resultant void content, with a focus on resin infusion flow rate, 2) applying statistical metrics to the formation, location and size of voids formed, and 3) correlate these metrics with the local mechanical properties of the composite laminate. The variation in dispersion and formation of micro-voids and macro-voids varied greatly between the rates of flow the infusion occurred, especially in the non-crimp carbon fiber samples. Higher flow rates led to lower volumes of micro-voids in the beginning section of the carbon fiber laminates with macro-voids being introduced approximately half-way through infusion. This was determined to have occurred decreasing pressure gradient as the flow front moved away from the inlet. This variation in void content per location on the laminate was more evident in the carbon fiber samples than the fiberglass samples. Micro-voids follow void formation modeling especially when coupled with a pressure threshold model. Macro-void formation was also demonstrated to correlate strongly to void formation models when united with void mobility theories and pressure thresholds. There is a quick decrease in mechanical properties after the first 1-2% of voids signaling strength is mostly sensitive to the first 0-2% void content. A slight decrease in SBS was noticed in fiberglass laminates, A-F as v0 increased but not as drastically as represented in the NCF laminates, G and H. The lower clarity in the exponential trend could be due to the lack of samples with v0 greater than 0% but less than 1%. Strength is not well correlated to void content above 2% and could possibly be related to void morphololgy.

The critical thickness at which a toughness transition occurs in a polymer was determined for the Dow Corning 4-3136 silicone resin. 4-3136 is macroscopically brittle, but becomes up to ten times more ductile when it is processed in the form of a sufficiently thin film. Thickness was controlled for the thin films of amorphous polymer through solution composition variation. The films were spun on highly polished stainless steel at a constant angular velocity. The transition was observed over a range of film thicknesses at several different curing temperatures. Observation of cracking induced by bending and tensile strain was used as the gauge for the transition from brittle to ductile. The critical thickness was observed to have an unambiguous value at low curing temperatures. At higher curing temperatures, the transition occurred more gradually. The critical thickness also increased up to intermediate curing temperatures, then decreased at the highest cure temperature. Crosslink density is theorized as the cause for this cure temperature induced alteration of the critical thickness.

Full text
Abstract:
Introduction: The circulating renin-angiotensin system (RAS) was originally described as a key endocrine regulator of intravascular homeostasis; however, the existence of a local (tissue) RAS has become increasingly reported in a variety of tissues including liver. RAS components have now also been detected in rat heart, brain and smooth muscle cell mitochondria as well as within intramitochondrial dense bodies of rat adrenal tissue. Further, reduced RAS levels have been associated with improved endurance performance and fatigue resistance in human skeletal muscle, suggesting that low RAS activity is associated with metabolic efficiency, potentially via RAS action upon, or within, mitochondria. However, such investigation has often relied heavily upon qualitative techniques (e.g. Western blotting, immunofluorescence and electron microscopy), which contain inherent limitations in that they completely rely upon the limited specificity of antibodies to demonstrate the existence of intra-mitochondrial RAS components. Methods: The presence of RAS components within the mitochondria of rat hepatic tissue and liver cell-lines was investigated via sub-fractionation of rat liver tissue and cell-lines, followed by Western blotting, as well as via immunofluorescence and confocal microscopy, and electron microscopy. The mitochondrial effects of stimulating or antagonizing hepatic RAS were assessed via functional fluorescence microscopy (for assessment of NADH, calcium and mitochondrial membrane potential) and measurement of oxygen consumption within live cells of a liver cell-line. Results: Western blotting, immunofluorescence and electron microscopy suggested the presence of RAS components within mitochondria; however, there was a lack of results consistency between techniques and the staining patterns were largely non-specific. Western blotting further demonstrated the presence of a prominent 55 kDa band, when immunostaining a mitochondrial fraction with (angiotensin-converting enzyme) ACE Cterminal antibody (usual size 180 kDa). This was further explored via isolation of the 55 kDa molecule and mass spectrometry to yield results consistent with non-specific staining only. Addition of RAS agonists or antagonists to live liver cell-lines demonstrated no consistent results, except at supra-physiological levels, where RAS antagonists improved oxygen consumption. Conclusions: Such data suggest that the previous descriptions of RAS components within mitochondria are likely to be secondary to methodological flaws, particularly the reliance upon single antibodies, which have subsequently been shown to have poor specificity. Thus, the effect of ang II on liver mitochondria is unlikely to be direct and any such action is likely to occur via one of several intracellular pathways, regulation of gene expression or mitochondrial biogenesis.

Tesis para optar al grado de Magíster en Marketing
El presente trabajo tiene por objetivo elaborar un plan de marketing para el lanzamiento de una nueva cerveza artesanal. El producto se enmarca dentro del dinámico mercado de la cerveza en Chile, en el que existe una gran variedad de marcas y tipos de cervezas, con un gran actor como CCU que ejerce una posición dominante en este mercado. Sin embargo, como se muestra más adelante, existe un nicho pujante que se ha desarrollado rápidamente en los últimos 15 años y consiste en la elaboración y venta de cervezas artesanales. La cerveza es una bebida alcohólica muy antigua, desarrollada por los pueblos de los imperios mesopotámicos y por los egipcios, que es el resultado de fermentar los cereales germinados en agua, en presencia de levadura. Aunque a nivel mundial, en el mercado existen cervezas de trigo, arroz, la más habitual es la obtenida a partir de la fermentación de la cebada. A pesar de su antigüedad, el gran periodo de auge de la cerveza es posterior a la segunda guerra mundial (1945 a 1965) donde la producción mundial se duplicó y se sentaron las bases de los actuales procesos de producción industrial, en desmedro muchas veces de los criterios de calidad. Hasta bien entrados los años setenta fueron desapareciendo grandes cantidades de recetas y se fue uniformizando mundialmente la producción. Sin embargo en las últimas décadas ha vuelto a aparecer la idea de producir cerveza artesanal, hasta el punto que importantes elaboradores de talla mediana han apostado por producir cervezas históricas resucitando con ello recetas perdidas.

Abstract:
The cost of manufacturing high quality composite components can be significantly reduced by using Out of Autoclave (OOA) processes if they can achieve final parts with a finish quality as high as that obtained using an autoclave process. Much research has been carried out recognising that regardless of the reinforcement fibre orientation, manufacturing of preimpregnated (prepregs) carbon components is much affected during its forming stage by fibre deformation and failure modes. This work sought to reduce wrinkling in the moulding of prepregs by introducing slip layers within the lay-up. Three types of slip layers were used: a dry fabric, a resin rich layer and a resin film. In order for the slip layers to be fully incorporated into the final laminate the resin content within the slip layer must be adjusted prior to crosslinking. In the case of dry fabric layer, additional resin must be introduced and in the case of a resin rich layer and resin film layer, excess resin has to be removed. The laminates used in the project were based on 2/2 twill and unidirectional carbon prepregs. These were manufactured by either Resin Infusion (RI) or Vacuum Bagging (VB). Resin adjustments were made at the same time. The 2/2 twill and unidirectional carbon prepregs were first characterised by Differential Scanning Calorimetry (DSC) and Dynamic Mechanical Thermal Analysis (DMTA) before RI and VB. Dry 2/2 twill and unidirectional carbon fabrics and/or Resin Film (for VB) or fabrics and Epoxy Resin (for RI) were introduced in several plybooks and then cured. Final parts were either made of 2/2 twill carbon or unidirectional carbon. The parts were used to investigate the relationship between individual plies during the consolidation of a plybook. The first characterisations were done on flat laminates. Also two moulds were manufactured and used to produce new parts for further characterisations. The first, an aluminium mould was machined using a Computer Numerical Control (CNC). The second mould was a fan blade, made using chopped strand mats. The final parts had 3, 4 or 6 plies. These parts were characterised using Optical Microscopy (OM), Scanning Electron Microscopy (SEM), and Torsion testing. The results provide a first step towards understanding how the friction at a ply/ply level can be influenced by the "starving" or the "enriching" of resin in a plybook during its consolidation. The work showed that in OOA manufacturing, the friction at a ply/ply level can be controlled by introducing Resin Film, Dry or Resin Rich Fabrics in a prepreg plybook. It was demonstrated that introducing lubrication to control ply friction during forming can result in quality part as high as that obtained from a traditional composite forming process. As the final parts were made using a fixed die mould and a vacuum bag, most of the plies in the layups could deform individually and accommodate interply shear. Torsion testing on a number of a random selection of samples showed negligible effects on shear stresses, strengths and modulus within the parts were negligible. It is argued that the flexibility of the vacuum bag could have had an impact on the layups during forming. The plies could conform to the mould easier. This work has potential for other applications. For example in match die moulding, introducing wet lubrication could improve interply shear during forming and help in improving accuracy and geometrical conformity of final parts. Furthermore, developing techniques to control friction during forming in OOA can be attractive to industries which could not afford to invest in this OOA prepreg technology. OOA processing times have become very attractive to industries such as the sporting good, automotive, wind energy and transportation. These industries could explore the opportunity presented by the work in this EngD thesis.

Full text
Abstract:

This thesis presents studies of the interactions between suspended particles and dissolved and colloidal substances (DCS) in process water. The main focus has been to determine if colloidal wood resin is adsorbed by suspended fines or fillers, and how the dissolved material influences this adsorption. The effect of some synthetic polymers on this adsorption has also been investigated.

Successive refining of mainly Norway spruce followed Successive refining of mainly Norway spruce followed by removal of the produced fines after each refining stage, resulted in fines with different physical and chemical properties. In the first refining stage mainly flake-like fines were produced, while more fibrillar fines were produced in later refining stages. The different types of fines were analysed for both the bulk and the surface composition. Variation in the chemical composition between the fines was particularly striking with regard to the surface composition. Special attention was also given to the amount and origin of charged groups since these may consume cationic additives in the papermaking process. After alkali treatment, between 80 and 90% of all the charged groups measured by polymer adsorption originated from three uronic acids.

Fines were shown to adsorb model colloidal wood resin, but the adsorption was greatly influenced by the pH or salt content. Also the amount of dissolved components in the suspension, which sterically stabilised the colloidal wood resin, was shown to strongly influence the adsorption of the colloidal wood resin to the fines. The flake-like fines adsorbed the colloidal wood resin to a higher extent than the fibrillar fines. This selectivity was also possible to obtain by using polyethyleneoxide (PEO). PEO removed the sterically stabilised colloidal wood resin more efficiently when flake-like fines rather than fibrillar fines were present. For comparison, cationic polyacrylamide (CPAM) did not have this selectivity. The selectivity of PEO was explained by a higher affinity to flake-like fines than fibrillar fines. It was shown that more PEO adsorbed to flake-like fines rather than to fibrillar ones. PEO may adsorb to extractive surfaces, but was inhibited by adsorbed components from the dissolved fraction. The degree of stabilisation was also shown to influence the adsorption of the colloidal wood resin by other particles like fillers. This adsorption, which was energetically favourable, did not occur at high concentrations of dissolved material.

Full text
Abstract:
Loblolly pines, Pinus taeda L., are a vital part of the timber industry throughout the southern United States and are susceptible to damage and mortality as a result of attack by southern pine beetles, Dendroctonus frontalis Zimmerman. The primary defense of loblolly pines against bark beetles is constitutive resin, which provides a physical barrier to beetle colonization. A study has been conducted to determine resin production heritablity in clonal loblolly pines. Samples were taken in the spring and late summer of 2005 and 2006 in Milton, FL and Walterboro, SC. Each site included nine complete random blocks containing improved and unimproved checks and 115 and 149 sampled clones, respectively. Two resin samples were collected at breast height from each tree after resin was allowed to flow for 22 +/- 2 hours. Samples were then dried until a subset reached constant mass and sample mass data were used to determine total resin flow repeatability. Total resin flow was found to be significantly higher in one family than the improved check. Resin production by clonal loblolly pines was found to have moderately high repeatability and low positive correlation with tree volume. Results indicate that clone selection that includes resin production as well as desirable growth characteristics can result in loblolly pines that display decreased susceptibility to the southern pine beetle.

Lowe, Julian Robert. "Void formation in resin transfer moulding." Thesis, University of Nottingham, 1993. http://eprints.nottingham.ac.uk/11626/.

Full text
Abstract:
In recent years interest has grown in the use of composite components within the automotive industry. Fibre reinforced plastic (FRP) components are of particular interest to the industry, since lower tooling costs and part consolidation can be utilised, whilst lighter, stiffer components can be produced. Several methods are available to produce FRP components at high volumes, including compression moulding (using dough and sheet moulding compounds), reinforced reaction injection moulding (RRIM) and liquid moulding processes (resin transfer moulding (RTM) and structural reaction injection moulding (SRIM)). RTM is a closed mould process, which is widely used to produce components economically in low volumes using matched moulds to produce two good surfaces. The absence of a high volume manufacturing technology, however, has impeded the acceptance and advance of RTM within the automotive industry. A research programme was established at the University of Nottingham to address the problems associated with the use of RTM for high volume manufacture. This programme has considered the topics of process technology, processing characteristics of polyester resin systems and fibre preforms, fibre wet-out and interfacial bonding, mould design, microwave pre-heating of reactive resin systems and process modelling. This thesis concerns the research which was undertaken to identify the causes of void formation during the impregnation and polymerisation stages of RTM, and methods of reducing the final void content within the component. The impregnation phase of the RTM process was identified as being the stage where the majority of voids were formed. A study of oil impregnation (having a similar viscosity to that of resin) into reinforcement was undertaken to determine the reasons for uneven flow and air entrapment. The dry reinforcements were studied to assess the microstructure of the preforms in order to determine reasons for obstruction of the resin flow. Fabric stitching, thermoplastic binder and size deposits were identified as potential causes of flow impediment. Fibre orientation and preform stacking were also assumed to assist in the development of uneven flow, leading to air entrapment. A major factor determining the formation of microvoids within fibre bundles was identified as the transverse impregnation of resin into high Tex fibre bundles. The major moulding process variables of injection pressure, vent pressure, fibre volume fraction, mould temperature and resin pre-heating have been assessed, to determine their effect on the void content within unidirectional and CFRM reinforced polyester laminates. It was observed that vacuum assistance during impregnation reduced void formation, although higher exotherm pressures and the possibility of monomer boiling arise from its use. A simple impregnation model was developed to assess the microscopic impregnation rates between fibre bundles, in the capillary between fibres and transversely into fibre bundles. The results from this model were compared with actual moulding histories. The findings of the overall work are discussed and suggestions proposed for the reduction of void content in RTM automotive components.

Abstract:
The renin-angiotensin-aldosterone system (RAAS) is one of the major regulators of blood pressure. The actions and generation of RAAS components at the tissue level are less well appreciated. This work was designed to investigate the vascular wall not only as a target of the RAAS, but also as one of its sources. Immunocytochemical and immunoblotting analysis revealed positive renin immunoreactivity in the cytoplasm of cultured bovine aortic endothelial cells. Two immunoreactive bands of molecular mass approximately 37,000 and 40,000 dalton were identified. In situ hybridization confirmed that renin mRNA was localized in the same cells. Reverse transcriptase-polymerase chain reaction (RT-PCR) using primers specific for human renin gave a clear single band with the predicted size for (pro)renin. These findings suggest that these vascular endothelial cells are a source of local synthesised renin. Conditioned medium from cultured bovine aortic endothelial cells (BAECCM) and rat aortic smooth muscle cells (RASMCCM) were shown to contain immunoreactive angiotensin II (Ang II) equivalent to 15.05 ± 4.67 pg/106 cells and 1 1.16 ± 1.8 pg/ 106 cells, respectively. Tritiated thymidine incorporation into aortic smooth muscle cells (ASMC) was increased by Ang II and by BAECCM. In both cases, this stimulated proliferation was inhibited by the Ang II type I (AT, ) receptor selective antagonist, losartan. Although tritiated thymidine uptake by rat aortic smooth muscle cells (RASMC) was not significantly enhanced by RASMCCM, it was significantly decreased by losartan in the presence of RASMCCM or of serum-free medium. Assay of RASMC proliferation by cell counting showed that the number of I cells in the presence of Ang II (10'6M) were nearly twice that in control cultures after r 2 days. These findings suggest that Ang II produced by ASMC locally may regulate ASMC growth in an autocrine or/and paracrine fashion, via the AT, receptor. RASMC was also shown to produce immunoreactive aldosterone. Ang II significantly enhanced aldosterone formation by RASMC. but not in the presence of losartan. Ang II stimulated 3H-thymidine uptake into RASMC was further enhanced by aldosterone, but inhibited by the aldosterone antagonist. spironolactone. and the 3ß-hydroxysteroid-dehydogenase inhibitor trilostane. These results suggest that the presence of locally generated aldosterone is essential for the stimulatory effects of Ang II, acting via the AT, receptor. on RASMC proliferation. Amplified products corresponding to transcripts of the CYP 11 BI gene were obtained by RT-PCR on RNA extracted from RASMC, using primers chosen from homologous parts of the exon I and exon 2 regions of CYP IIBI and CYP II B2 genes. Sequencing showed the presence of CYP 11 B1 transcript, but gave no evidence for CYP 11 B2 gene transcription. RT-PCR also gave a band corresponding to the 770 bp fragment from bases - 486 (upstream) to + 284 (exon 2) bp of the CYP 1lB1 gene. Furthermore, the present experiments demonstrated the transcription of the sequences 183-480 bp upstream from the CYP 11 B1 gene, and the use of competitive RT-PCR showed this was regulated by Ang 11. Thus. cultured RASMC may be the site of Ang 11 regulated transcription of a longer fragment of the CYP 11 B1 gene than generally expected. Finally, use of immunofluorescence and immunoblotting demonstrated the presence of an apparent binding carrier for 18-OH-DOC in cultured RASMC similar to that found in the rat adrenal.

Abstract:
Renin is an enzyme that catalyzes the rate-limiting step in the production of angiotensin peptides, and is thus a key regulator of processes controlled by angiotensin such as blood pressure, hydromineral balance, and metabolism. Our laboratory and others have previously identified a novel isoform of renin (icRen) which, as a result of the utilization of an alternate first exon, lacks the signal peptide and first third of the pro-segment of classical secreted renin (sRen). This alternate icRen isoform thus remains within the cytoplasm of the cell, but is constitutively active. Here, we report that while sRen is the predominant form of renin expressed in most tissues during development, icRen is the predominant form of renin within the adult brain. Thus, we hypothesized that sRen and icRen play distinct physiological roles in adult mice. To examine this hypothesis, we have utilized the Cre-LoxP system to selectively delete either isoform globally or within selected cell types such as neurons and glia. We have successfully developed a "sRen-flox" model, in which endogenous mouse sRen isoform can be selectively deleted, while not affecting endogenous icRen production. Breeding these mice against the E2A-Cre, Nestin-Cre, and GFAP-Cre mouse lines resulted in global-, neuronal-, and glial-specific knockouts of sRen, respectively. Physiological characterization of resulting mice has uncovered postnatal lethality, hypotension, renal atrophy, vascular dysfunction and decreased body weight and white adipose in the global knockouts. Depletion of sRen from only neuronal or glial cells does not appear to alter any of these phenotypes at baseline. From these data, we conclude that while peripheral sRen is of primary importance to blood pressure regulation, hydromineral balance, and metabolism, central expression of this isoform is unimportant. Further, comparison of our results to published findings from global total renin knockout models indirectly supports a role for icRen in the brain. We are currently in the process of generating icRen-flox and subsequent knockout mice, which will be useful models to directly analyze the physiological role(s) of icRen.

Abstract:
The renin angiotensin system (RAS) is critical for the regulation of blood pressure, electrolyte/fluid, and metabolic homeostasis. Regulation of the RAS is important in the development and treatment of hypertension. As part of the rate-limiting step in a cascade of events ending in the production of angiotensin II, renin is a major regulator of the RAS. Its expression is localized to the juxtaglomerular (JG) cells of the JG apparatus where it is exquisitely located to respond to various physiological cues. Understanding the regulation of renin expression and development of the juxtaglomerular cells is critical. Two regulatory elements, the enhancer and proximal promoter, have been found to be important in controlling cell- and tissue- specific baseline expression of the renin gene. Within the enhancer is a hormone response element (HRE) which confers a high level of activity to the enhancer. Nuclear receptors that bind this element have been found to bind the HRE and regulate renin promoter transcriptional activity. We have previously characterized the role of the orphan nuclear receptor Nr2f6 as a negative regulator of renin expression that mediates its effects through the HRE. However, gel shift assays indicate that there are other transcription factors binding this element. We have identified other orphan nuclear receptors that regulate renin expression. The first, Nr2f2 acts as a negative regulator of renin promoter activity but does not appear to affect baseline expression of the endogenous renin gene. The other, Nr4a1, is a positive regulator of renin expression, but it does not appear to mediate its effects through the HRE. The transcriptional regulation of gene expression is controlled by regulatory elements separated by large distances from promoters. We and others have found that short transgenes of the human renin (hREN) locus are not sufficient to protect them from positional effects that can be exerted upon them by neighboring regulatory elements. We discovered a random truncation in a large genomic construct of the hREN gene that resulted in ubiquitous expression of renin not seen with the intact form. By locating the genomic insertion site of that transgene in the Zbtb20 gene, we found that the hREN promoter had come under control of that gene's regulatory elements. The gene downstream of renin however maintained its tissue-specific expression. We found that CCCTC-binding factor (CTCF) bound to chromatin in and around the renin locus. The presence of CTCF suggests that insulator elements are present in the renin locus, and their loss likely explains the results above. Finally, we assessed the role of microRNAs in the development of renin expressing cells in the mouse kidneys by cell-specific deletion of the processing enzyme Dicer. This resulted in reduction of renin expression and a decrease in the number of renin expressing cells in the kidney. Mice were hypotensive and had several kidney abnormalities including a hypertrophied vasculature and striped fibrosis. These results indicate that Dicer and the miRNAs it processes are critical for the development and maintenance of renin expressing cells that contribute to normal kidney development.

Abstract:
Left ventricular hypertrophy (LVH) in response to pressure overload is associated with increased cardiovascular morbidity and mortality, making its prevention an important therapeutic goal. The role of a calcineurin-dependent molecular pathway in the induction of pressure-overload LVH is controversial. The present study tested the hypothesis that, in the setting of LV pressure overload, activation of the systemic renin-angiotensin system was necessary for activation of this calcineurin pathway. Mild LV pressure overload was induced in male Wistar rats by abdominal aortic constriction (AAC) or transverse aortic arch constriction (TAC), producing well-matched pressure gradients of 37 ?? 8 and 35 ?? 15 mmHg, respectively. Tight transverse aortic arch constriction (TTAC) in additional animals produced a pressure gradient of 75 ?? 15 mmHg. Only AAC increased plasma renin concentration and activated the calcineurin pathway, indicated by increased nuclear NFAT3 content. Plasma renin concentration and nuclear NFAT3 content were unchanged in TAC and TTAC animals. AAC animals developed more LVH 21 days post-banding than TAC and TTAC animals: the slope of the relationship between LV/body weight ratio and systolic blood pressure was much steeper in AAC animals than the combined TAC and TTAC animals (20x10-6 versus 5x10-6, p<0.001). Treatment with the calcineurin inhibitor FK506 did not significantly alter the slope of this relationship in the combined TAC and TTAC animals (8x10-6), but FK506 abolished this relationship in AAC animals (-5x10-6, R =0.0003). These data indicate that activation of the calcineurin pathway occurs only in high-renin hypertension, providing an additional stimulus to LVH induction. Calcineurin plays no role in the induction of LVH in low-renin hypertension, which is much more common clinically.
