The search for medical therapies to prevent or slow the progression of HVDs has been hampered by our poor understanding of the progression from subclinical to symptomatic phases, and our limited knowledge of the molecular signals that control the susceptibility of valve interstitial cells to pathological remodeling. Clinical evidence has suggested a link between certain neurotransmitters and valvular diseases of the heart. The fenfluramine–phentermine appetite suppressants popular in the 1980s were linked to mitral valve dysfunction, and ergot-derived dopamine agonists for Parkinson’s disease have been associated with an increased risk of mitral and aortic valve regurgitation. The effect does not appear to be limited to medications, as valvular pathologies have also been observed in patients with carcinoid tumours of serotonin-producing enterochromaffin cells. The role of neurotransmitter molecules in valve pathology has not been adequately characterized and may represent a target for future medical therapies. Here we present current evidence from both clinical and basic science suggesting a link between neurotransmitters and HVDs, opening the door to future research in this area.

  • Matricellular protein thrombospondin-1 in pulmonary hypertension: multiple
           pathways to disease
    • Authors: Rogers NM; Ghimire K, Calzada MJ, et al.
      Pages: 858 - 868
      Abstract: Matricellular proteins are secreted molecules that have affinities for both extracellular matrix and cell surface receptors. Through interaction with structural proteins and the cells that maintain the matrix these proteins can alter matrix strength. Matricellular proteins exert control on cell activity primarily through engagement of membrane receptors that mediate outside-in signaling. An example of this group is thrombospondin-1 (TSP1), first identified as a component of the secreted product of activated platelets. As a result, TSP1 was initially studied in relation to coagulation, growth factor signaling and angiogenesis. More recently, TSP1 has been found to alter the effects of the gaseous transmitter nitric oxide (NO). This latter capacity has provided motivation to study TSP1 in diseases associated with loss of NO signaling as observed in cardiovascular disease and pulmonary hypertension (PH). PH is characterized by progressive changes in the pulmonary vasculature leading to increased resistance to blood flow and subsequent right heart failure. Studies have linked TSP1 to pre-clinical animal models of PH and more recently to clinical PH. This review will provide analysis of the vascular and non-vascular effects of TSP1 that contribute to PH, the experimental and translational studies that support a role for TSP1 in disease promotion and frame the relevance of these findings to therapeutic strategies.

  • Role of phosphatase and tensin homolog in hypoxic pulmonary
    • Authors: Krauszman A; Mak TW, Szaszi K, et al.
      Pages: 869 - 878
      Abstract: AimsHypoxic pulmonary vasoconstriction (HPV) redistributes blood flow from poorly ventilated to better aerated areas in the lung, thereby optimizing ventilation-perfusion ratio (V/Q). Pulmonary artery smooth muscle cell (PASMC) contraction in response to hypoxia is triggered by Ca2+ influx via transient receptor potential canonical 6 (TRPC6) cation channels that have translocated to caveolae in the plasma membrane. Since phosphatase and tensin homolog (PTEN) was suggested to regulate TRPC6 in endothelial cells, we aimed to define its role in the hypoxic response of PASMCs and as a putative mediator of HPV.Methods and resultsIn isolated perfused mouse lungs, smooth muscle specific PTEN deficiency attenuated pulmonary vasoconstriction in response to hypoxia but not to angiotensin II (Ang II). Analogously, siRNA-mediated knock down of PTEN in human PASMC inhibited the hypoxia-induced increase in cytosolic Ca2+ concentration ([Ca2+]i). Co-immunoprecipitation and proximity ligation assays revealed increased interaction of PTEN with TRPC6 in human PASMC and murine lungs in response to hypoxia. In hypoxic PASMC, both PTEN and TRPC6 translocated to caveolae, and this response was blocked by pharmacological inhibition of Rho-associated protein kinase (ROCK) which in parallel prevented PTEN-TRPC6 interaction, hypoxia-induced [Ca2+]i increase, and HPV in PASMC and murine lungs, respectively.ConclusionOur data indicate a novel interplay between ROCK and [Ca2+]i signalling in HPV via PTEN, in that ROCK mediates interaction of PTEN and TRPC6 which then conjointly translocate to caveolae allowing for Ca2+ influx into and subsequent contraction of PASMC.

  • Increased collagen within the transverse tubules in human heart failure
    • Authors: Crossman DJ; Shen X, Jüllig M, et al.
      Pages: 879 - 891
      Abstract: AimsIn heart failure transverse-tubule (t-tubule) remodelling disrupts calcium release, and contraction. T-tubules in human failing hearts exhibit increased labelling by wheat germ agglutinin (WGA), a lectin that binds to the dystrophin-associated glycoprotein complex. We hypothesized changes in this complex may explain the increased WGA labelling and contribute to t-tubule remodelling in the failing human heart. In this study we sought to identify the molecules responsible for this increased WGA labelling.Methods and resultsConfocal and super-resolution fluorescence microscopy and proteomic analyses were used to quantify left ventricle samples from healthy donors and patients with idiopathic dilated cardiomyopathy (IDCM). Confocal microscopy demonstrated both WGA and dystrophin were located at t-tubules. Super-resolution microscopy revealed that WGA labelling of t-tubules is largely located within the lumen while dystrophin was restricted to near the sarcolemma. Western blots probed with WGA reveal a 5.7-fold increase in a 140 kDa band in IDCM. Mass spectrometry identified this band as type VI collagen (Col-VI) comprised of α1(VI), α2(VI), and α3(VI) chains. Pertinently, mutations in Col-VI cause muscular dystrophy. Western blotting identified a 2.4-fold increased expression and 3.2-fold increased WGA binding of Col-VI in IDCM. Confocal images showed that Col-VI is located in the t-tubules and that their diameter increased in the IDCM samples. Super-resolution imaging revealed Col-VI was restricted to the t-tubule lumen where increases were associated with displacement in the sarcolemma as identified from dystrophin labelling. Samples were also labelled for type I, III, and IV collagen. Both confocal and super-resolution imaging identified that these collagens were also present within t-tubule lumen.ConclusionIncreased expression and labelling of collagen in IDCM samples indicates fibrosis may contribute to t-tubule remodelling in human heart failure.

  • Tissue transglutaminase induction in the pressure-overloaded myocardium
           regulates matrix remodelling
    • Authors: Shinde AV; Dobaczewski M, de Haan JJ, et al.
      Pages: 892 - 905
      Abstract: AimsTissue transglutaminase (tTG) is induced in injured and remodelling tissues, and modulates cellular phenotype, while contributing to matrix cross-linking. Our study tested the hypothesis that tTG may be expressed in the pressure-overloaded myocardium, and may regulate cardiac function, myocardial fibrosis and chamber remodelling.Methods and resultsIn order to test the hypothesis, wild-type and tTG null mice were subjected to pressure overload induced through transverse aortic constriction. Moreover, we used isolated cardiac fibroblasts and macrophages to dissect the mechanisms of tTG-mediated actions. tTG expression was upregulated in the pressure-overloaded mouse heart and was localized in cardiomyocytes, interstitial cells, and in the extracellular matrix. In contrast, expression of transglutaminases 1, 3, 4, 5, 6, 7 and FXIII was not induced in the remodelling myocardium. In vitro, transforming growth factor (TGF)-β1 stimulated tTG synthesis in cardiac fibroblasts and in macrophages through distinct signalling pathways. tTG null mice had increased mortality and enhanced ventricular dilation following pressure overload, but were protected from diastolic dysfunction. tTG loss was associated with a hypercellular cardiac interstitium, reduced collagen cross-linking, and with accentuated matrix metalloproteinase (MMP)2 activity in the pressure-overloaded myocardium. In vitro, tTG did not modulate TGF-β-mediated responses in cardiac fibroblasts; however, tTG loss was associated with accentuated proliferative activity. Moreover, when bound to the matrix, recombinant tTG induced synthesis of tissue inhibitor of metalloproteinases (TIMP)-1 through transamidase-independent actions.ConclusionsFollowing pressure overload, endogenous tTG mediates matrix cross-linking, while protecting the remodelling myocardium from dilation by exerting matrix-preserving actions.

  • Impact of acute hypertension transients on diastolic function in patients
           with heart failure with preserved ejection fraction
    • Authors: Pérez del Villar C; Savvatis K, López B, et al.
      Pages: 906 - 914
      Abstract: AimTo address the mechanisms responsible for the increase in LV filling pressures induced by acute hypertension transients in patients with heart failure with preserved ejection fraction (HFpEF).Methods and resultsMultiple-beat pressure–volume loops were recorded during inferior vena cava occlusion in 39 HFpEF patients and 20 controls during handgrip and atrial pacing. We measured the contribution of relaxation, elastic recoil, and stiffness to instantaneous diastolic pressure using a novel processing method. Fibrosis was quantified from endomyocardial biopsies. HFpEF patients showed higher diastolic pressures and stiffness constant than controls (P < 0.05 for all). As opposed to controls, all intrinsic global diastolic properties were sensitive to acute changes in systolic pressure in the HFpEF group. In fact, the stiffness constant increased by more than 50% during handgrip in HFpEF patients (P < 0.05), tightly related to changes in systolic pressure (fixed-effect = 0.26 mm Hg per mm Hg [95% CI = 0.15–0.37]; P < 0.0001). Incomplete relaxation contributed to increasing pressure before atrial contraction, but changes in end-diastolic pressure was mostly caused by the increase in stiffness. The degree of pressure-sensitivity of stiffness correlated with myocardial collagen volume and crosslinking (R = 0.40 to 0.82 for all).ConclusionAcute chamber stiffening is the main mechanism responsible for rising late-diastolic pressures when HFpEF patients undergo hypertension transients. This stiffening behaviour is related to impaired dynamic systolic–diastolic interactions and correlates with matrix remodelling. Ventricular-vascular relationships are a promising target in HFpEF and should be taken into account when assessing diastolic function.

  • Early sensitization of myofilaments to Ca 2+ prevents genetically linked
           dilated cardiomyopathy in mice
    • Authors: Alves ML; Warren CM, Simon JN, et al.
      Pages: 915 - 925
      Abstract: BackgroundDilated cardiomoypathies (DCM) are a heterogeneous group of inherited and acquired diseases characterized by decreased contractility and enlargement of cardiac chambers and a major cause of morbidity and mortality. Mice with Glu54Lys mutation in α-tropomyosin (Tm54) demonstrate typical DCM phenotype with reduced myofilament Ca2+ sensitivity. We tested the hypothesis that early sensitization of the myofilaments to Ca2+ in DCM can prevent the DCM phenotype.Methods and resultsTo sensitize Tm54 myofilaments, we used a genetic approach and crossbred Tm54 mice with mice expressing slow skeletal troponin I (ssTnI) that sensitizes myofilaments to Ca2+. Four groups of mice were used: non-transgenic (NTG), Tm54, ssTnI and Tm54/ssTnI (DTG). Systolic function was significantly reduced in the Tm54 mice compared to NTG, but restored in DTG mice. Tm54 mice also showed increased diastolic LV dimensions and HW/BW ratios, when compared to NTG, which were improved in the DTG group. β-myosin heavy chain expression was increased in the Tm54 animals compared to NTG and was partially restored in DTG group. Analysis by 2D-DIGE indicated a significant decrease in two phosphorylated spots of cardiac troponin I (cTnI) in the DTG animals compared to NTG and Tm54. Analysis by 2D-DIGE also indicated no significant changes in troponin T, regulatory light chain, myosin binding protein C and tropomyosin phosphorylation.ConclusionOur data indicate that decreased myofilament Ca2+ sensitivity is an essential element in the pathophysiology of thin filament linked DCM. Sensitization of myofilaments to Ca2+ in the early stage of DCM may be a useful therapeutic strategy in thin filament linked DCM.

  • Tyrosine phosphorylation of eNOS regulates myocardial survival after an
           ischaemic insult: role of PYK2
    • Authors: Bibli S; Zhou Z, Zukunft S, et al.
      Pages: 926 - 937
      Abstract: AimsEndothelial nitric oxide (NO) synthase (eNOS) is known to play a cardioprotective protective. However, the molecular mechanisms regulating eNOS activity during ischaemia/reperfusion (I/R) injury are incompletely understood. eNOS is a substrate for several kinases that positively or negatively affect its enzymatic activity. Herein, we sought to correlate eNOS phosphorylation status with cardiomyocyte survival and we investigated the contribution of the proline-rich tyrosine kinase 2 (PYK2)/eNOS axis to the regulation of myocardial infarct size in vivo.Methods and resultsExposure of H9c2 cardiomyocytes to H2O2 lead to PYK2 phosphorylation on its activator site (Y402) and eNOS phosphorylation on the inhibitor site Y656 and the activator site S1176. Both H2O2–induced eNOS phosphorylation events were abolished by PYK2 pharmacological inhibition or gene knockdown. Activity assays demonstrated that phosphorylation of the tyrosine inhibitory site exerts a dominant effect over S1176. In cardiomyocytes subjected to oxidative stress or oxygen-glucose deprivation, inhibition of PYK2 limited cell injury; this effect was prevented by inhibition of NO production. In vivo, ischaemia-reperfusion induced an early activation of PYK2, leading to eNOS phosphorylation on Y656, which, in turn, reduced NO output, as judged by the low tissue levels of its downstream effector cGMP. Moreover, pharmacological blockade of PYK2 alleviated eNOS inhibition and prevented cardiac damage following I/R injury in wild-type, but not in eNOS KO mice.ConclusionThe current studies demonstrate that PYK2 is a pivotal regulator of eNOS function in myocardial infarction and identify PYK2 as a novel therapeutic target for cardioprotection.

  • Therapeutic inhibition of miR-375 attenuates post-myocardial infarction
           inflammatory response and left ventricular dysfunction via PDK-1-AKT
           signalling axis
    • Authors: Garikipati VS; Verma SK, Jolardarashi D, et al.
      Pages: 938 - 949
      Abstract: AimsIncreased miR-375 levels has been implicated in rodent models of myocardial infarction (MI) and with patients with heart failure. However, no prior study had established a therapeutic role of miR-375 in ischemic myocardium. Therefore, we assessed whether inhibition of MI-induced miR-375 by LNA anti-miR-375 can improve recovery after acute MI.Methods and resultsTen weeks old mice were treated with either control or LNA anti miR-375 after induction of MI by LAD ligation. The inflammatory response, cardiomyocyte apoptosis, capillary density and left ventricular (LV) functional, and structural remodelling changes were evaluated. Anti-miR-375 therapy significantly decreased inflammatory response and reduced cardiomyocyte apoptosis in the ischemic myocardium and significantly improved LV function and neovascularization and reduced infarct size. Repression of miR-375 led to the activation of 3-phosphoinositide-dependent protein kinase 1 (PDK-1) and increased AKT phosphorylation on Thr-308 in experimental hearts. In corroboration with our in vivo findings, our in vitro studies demonstrated that knockdown of miR-375 in macrophages modulated their phenotype, enhanced PDK-1 levels, and reduced pro-inflammatory cytokines expression following LPS challenge. Further, miR-375 levels were elevated in failing human heart tissue.ConclusionTaken together, our studies demonstrate that anti-miR-375 therapy reduced inflammatory response, decreased cardiomyocyte death, improved LV function, and enhanced angiogenesis by targeting multiple cell types mediated at least in part through PDK-1/AKT signalling mechanisms.

  • Delayed, oral pharmacological inhibition of calpains attenuates adverse
           post-infarction remodelling
    • Authors: Poncelas M; Inserte J, Aluja D, et al.
      Pages: 950 - 961
      Abstract:  Calpains activate during myocardial ischemia-reperfusion and contribute to reperfusion injury. Studies in transgenic animals with altered calpain/calpastatin system subjected to permanent ischemia suggest that calpains are also involved in post-infarction remodelling and heart failure.AimsTo determine whether delayed oral administration of the calpain inhibitor SNJ-1945 reduces adverse myocardial remodelling and dysfunction following transient coronary occlusion.Methods and resultsMale Sprague–Dawley rats were subjected to 30 min of ischemia followed by 21 days of reperfusion and received the calpain inhibitor SNJ-1945 intraperitoneally at the onset of reperfusion (Acute group), orally starting after 24 h of reperfusion and for 14 days (Chronic group), or the combination of both treatments. Calpain-1 and calpain-2 protein content increased and correlated with higher calpain activity in control hearts. Administration of SNJ-1945 attenuated calpain activation, and reduced scar expansion, ventricular dilation and dysfunction in both acute and chronic groups. Acute treatment reduced infarct size in hearts reperfused for 24 h and inflammation measured after 3 days. Delayed, chronic oral administration of SNJ-1945 attenuated inflammation, cardiomyocyte hypertrophy and collagen infiltration in the non-infarcted myocardium at 21 days in correlation with increased levels of IĸB and reduced NF-ĸB activation. In cultured fibroblasts, SNJ-1945 attenuated TGF-β1-induced fibroblast activation.ConclusionsOur data demonstrate for the first time that long-term calpain inhibition is possible with delayed oral treatment, attenuates adverse post-infarction remodelling, likely through prevention of NF-ĸB activation, and may be a promising therapeutic intervention to prevent adverse remodelling and heart failure in patients with acute myocardial infarction.

  • Sensory innervation of perivascular adipose tissue: a crucial role in
           artery vasodilatation and leptin release
    • Authors: Abu Bakar H; Robert Dunn W, Daly C, et al.
      Pages: 962 - 972
      Abstract: AimsElectrical field stimulation (EFS) elicits robust sensory neurogenic relaxation responses in the rat isolated mesenteric arterial bed but these responses are absent or difficult to demonstrate in isolated arteries. We believe that this mismatch is due to the absence of perivascular adipose tissue (PVAT) as it is conventionally removed in studies on isolated vessels. We aimed to determine whether sensory nerves are expressed in PVAT, their physiological roles and their possible interactions with PVAT-derived adipokines.Methods and resultsUsing confocal imaging, enzyme immunoassay (EIA), myography, vascular perfusion, and multiplex analysis of rat mesenteric arteries, we show that PVAT is crucial for the roles of sensory nerves in control of vasomotor tone and adipokine release. Immunofluorescence double staining showed co-expression of calcitonin gene-related peptide (CGRP; sensory neurotransmitter) and PGP9.5 (neuronal marker) in PVAT of mesenteric arteries. CGRP release from dissected PVAT, measured using EIA, was increased by capsaicin which activates sensory nerves. EFS in both mesenteric arteries and perfused mesenteric arterial beds, with and without PVAT, demonstrated neurogenic relaxation in the presence of PVAT, which was greatly attenuated in preparations without PVAT. Neurogenic relaxation due to EFS was associated with release of leptin in PVAT-intact mesenteric arterial beds, which was abolished in preparations without PVAT. Exposure to low oxygen was associated with an attenuated leptin and adiponectin release, but an increase in IL-6 release, from mesenteric arterial beds. Exogenous leptin augmented relaxation to CGRP in mesenteric arteries.ConclusionThese data show, for the first time, expression of sensory nerves within PVAT and that PVAT is crucial for sensory neurogenic vasorelaxation and crosstalk with adipocytes leading to leptin release, which may augment CGRP-mediated relaxation; leptin release is abolished after exposure to conditions of reduced oxygenation.

  • Partitioning the heritability of coronary artery disease highlights the
           importance of immune-mediated processes and epigenetic sites associated
           with transcriptional activity
    • Authors: Nikpay M; Stewart AR, McPherson R.
      Pages: 973 - 983
      Abstract: AimsWith the availability of genome-wide genotype data from GWAS studies, it is now possible to compute the genetic relatedness among individuals and estimate its contribution (SNP-based heritability) to phenotypic variance using Mixed-Linear-Models (MLMs). The estimated heritability can be partitioned according to biological features to gain insight into the genetic architecture of a disease. Here, we aimed to examine the genetic structure of coronary artery disease (CAD).Methods and resultsWe investigated the genetic structure of CAD using 3,163,082 autosomal genome-wide SNPs (MAF ≥ 0.01) and MLMs in a sample of genetically ‘unrelated’ 4535 cases and 2977 controls. We find that genome-wide SNPs explain 22% of liability to CAD (55% of narrow-sense heritability) and sex-differences in CAD is not due to common SNPs on autosomal chromosomes. Heritability was proportionally distributed across the allele frequency spectrum and notably enriched among genic SNPs. We identified a number of modules that are significantly associated with CAD including: Dendritic cells stimulation; Basigin interactions; and a Cancer module. Of note, genes involved in inflammation account for one-fifth of SNP-based heritability. Heritability-enrichment analysis showed significant enrichment in epigenetic sites associated with transcriptionally activity; namely, enhancers, H3K9ac/H3K27ac/H3K4me1/H3K4me3 histone modifications, and Fetal DNase I hypersensitivity sites whereas heritability was highly depleted in transcriptionally repressed regions.ConclusionsMore individual SNP associations will be detected for CAD as sample size increases. The identified modules provide further biological insight for CAD and highlight the importance of immune-mediated processes in CAD pathogenesis. Finally, we showed that genetic liability to CAD is mainly attributed to epigenetic sites associated with transcriptional activity which encourage the design of custom sequencing/genotyping panels based on transcriptionally active regions.

  • Regional acidosis locally inhibits but remotely stimulates Ca 2+ waves in
           ventricular myocytes
    • Authors: Ford KL; Moorhouse EL, Bortolozzi M, et al.
      Pages: 984 - 995
      Abstract: AimsSpontaneous Ca2+ waves in cardiomyocytes are potentially arrhythmogenic. A powerful controller of Ca2+ waves is the cytoplasmic H+ concentration ([H+]i), which fluctuates spatially and temporally in conditions such as myocardial ischaemia/reperfusion. H+-control of Ca2+ waves is poorly understood. We have therefore investigated how [H+]i co-ordinates their initiation and frequency.Methods and resultsSpontaneous Ca2+ waves were imaged (fluo-3) in rat isolated ventricular myocytes, subjected to modest Ca2+-overload. Whole-cell intracellular acidosis (induced by acetate-superfusion) stimulated wave frequency. Pharmacologically blocking sarcolemmal Na+/H+ exchange (NHE1) prevented this stimulation, unveiling inhibition by H+. Acidosis also increased Ca2+ wave velocity. Restricting acidosis to one end of a myocyte, using a microfluidic device, inhibited Ca2+ waves in the acidic zone (consistent with ryanodine receptor inhibition), but stimulated wave emergence elsewhere in the cell. This remote stimulation was absent when NHE1 was selectively inhibited in the acidic zone. Remote stimulation depended on a locally evoked, NHE1-driven rise of [Na+]i that spread rapidly downstream.ConclusionAcidosis influences Ca2+ waves via inhibitory Hi+ and stimulatory Nai+ signals (the latter facilitating intracellular Ca2+-loading through modulation of sarcolemmal Na+/Ca2+ exchange activity). During spatial [H+]i-heterogeneity, Hi+-inhibition dominates in acidic regions, while rapid Nai+ diffusion stimulates waves in downstream, non-acidic regions. Local acidosis thus simultaneously inhibits and stimulates arrhythmogenic Ca2+-signalling in the same myocyte. If the principle of remote H+-stimulation of Ca2+ waves also applies in multicellular myocardium, it raises the possibility of electrical disturbances being driven remotely by adjacent ischaemic areas, which are known to be intensely acidic.
