Abstract
Arginine vasopressin (AVP) is a key contributor to heart failure (HF), but the underlying mechanisms remain unclear. In the present study, a mouse model of HF and human cardiomyocyte (HCM) cells treated with dDAVP are generated in vivo and in vitro, respectively. Hematoxylin and eosin (HE) staining is used to evaluate the morphological changes in the myocardial tissues. A colorimetric method is used to measure the iron concentration, Fe 2+ concentration and malondialdehyde (MDA) level. Western blot analysis is used to examine the protein levels of the V1a receptor (V1aR), calcineurin (CaN), nuclear factor of activated T cells isoform C3 (NFATC3), glutathione peroxidase 4 (GPX4) and acyl-CoA synthase long chain family member 4 (ACSL4). Immunoprecipitation (IP) and luciferase reporter assays are performed to determine the interaction between NFATC3 and ACSL4. Both in vivo and in vitro experiments reveal that the V1aR-CaN-NFATC3 signaling pathway and ferroptosis are upregulated in HFs, which are verified by the elevated protein levels of V1aR, CaN, NFATC3 and ACSL4; reduced GPX4 protein level; and enhanced Fe 2+ and MDA levels. We further find that inhibiting NFATC3 by suppressing the V1aR/CaN/NFATC3 pathway via V1aR/CaN inhibitors or sh-NFATC3 not only alleviates HF but also inhibits AVP-induced ferroptosis. Mechanistically, sh-NFATC3 significantly reverses the increase in AVP-induced ACSL4 protein level, Fe 2+ concentration, and MDA level by directly interacting with ACSL4. Our results demonstrate that AVP enhances ACSL4 expression by activating the V1aR/CaN/NFATC3 pathway to induce ferroptosis, thus contributing to HF. This study may lead to the proposal of a novel therapeutic strategy for HF.

Ninsiima LR, Chiumia IK, Ndejjo R. Factors influencing access to and utilisation of youth-friendly sexual and reproductive health services in sub-Saharan Africa: a systematic review. Reprod Health 2021; 18:135. [PMID: 34176511 PMCID: PMC8237506 DOI: 10.1186/s12978-021-01183-y] [Citation(s) in RCA: 46] [Impact Index Per Article: 15.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2020] [Accepted: 06/16/2021] [Indexed: 11/25/2022] Open
Abstract
Background Despite the global agreements on adolescents’ sexual and reproductive health and rights, access to and utilisation of these services among the youth/adolescents remain unsatisfactory in low- and middle-income countries which are a significant barrier to progress in this area. This review established factors influencing access and utilisation of youth-friendly sexual and reproductive health services (YFSRHS) among the youth in sub-Saharan Africa to inform programmatic interventions. Methodology A systematic review of studies published between January 2009 and April 2019 using PubMed, Web of Science, EMBASE, Medline, and Cochrane Library, and Google Scholar databases was conducted. Studies were screened based on the inclusion criteria of barriers and facilitators of implementation of YFSRHS, existing national policies on provision of YFSRHS, and youth’s perspectives on these services. Findings A total of 23,400 studies were identified through database search and additional 5 studies from other sources. After the full-text screening, 20 studies from 7 countries met the inclusion criteria and were included in the final review. Structural barriers were the negative attitude of health workers and their being unskilled and individual barriers included lack of knowledge among youth regarding YFSRHS. Facilitators of utilisation of the services were mostly structural in nature which included community outreaches, health education, and policy recommendations to improve implementation of the quality of health services and clinics for adolescents/youth to fit their needs and preferences. Conclusion Stakeholder interventions focusing on implementing YFSRHS should aim at intensive training of health workers and put in place quality implementation standard guidelines in clinics to offer services according to youth’s needs and preferences. In addition, educating the youth through community outreaches and health education programs for those in schools can facilitate utilisation and scale up of the service. Supplementary Information The online version contains supplementary material available at 10.1186/s12978-021-01183-y. Access and utilisation of Youth-friendly sexual and reproductive health is still a big challenge for the youth especially in sub-Saharan Africa. In this study, we explored the underlying reasons for the low access and utilisation of youth-friendly sexual and reproductive health services and potential solutions to the problem. Articles used in this study were retrieved from different data sources and those that contained barriers and facilitators of access and utilisation of youth-friendly sexual and reproductive health services implementation were summarised. The key barriers were negative attitude of health workers and their being unskilled emanating from the administrative section theme. The individual factor was the lack of knowledge among youth. The promoters of utilisation were community outreaches, health education and improvement of the quality of services in the clinics for adolescents/ young people’s needs. Moving forward, stakeholders should aim at increasing the training of health workers and improving the quality of services being offered to the youth. To address the individual barriers, youth should be reached with information through community outreaches and education in schools.

AAV-mediated expression of NFAT decoy oligonucleotides protects from cardiac hypertrophy and heart failure. Basic Res Cardiol 2021; 116:38.

Abstract
Previous studies have underlined the substantial role of nuclear factor of activated T cells (NFAT) in hypertension-induced myocardial hypertrophy ultimately leading to heart failure. Here, we aimed at neutralizing four members of the NFAT family of transcription factors as a therapeutic strategy for myocardial hypertrophy transiting to heart failure through AAV-mediated cardiac expression of a RNA-based decoy oligonucleotide (dON) targeting NFATc1-c4. AAV-mediated dON expression markedly decreased endothelin-1 induced cardiomyocyte hypertrophy in vitro and resulted in efficient expression of these dONs in the heart of adult mice as evidenced by fluorescent in situ hybridization. Cardiomyocyte-specific dON expression both before and after induction of transverse aortic constriction protected mice from development of cardiac hypertrophy, cardiac remodeling, and heart failure. Singular systemic administration of AAVs enabling a cell-specific expression of dONs for selective neutralization of a given transcription factor may thus represent a novel and powerful therapeutic approach.

Very Low-Density Lipoproteins of Metabolic Syndrome Modulates STIM1, Suppresses Store-Operated Calcium Entry, and Deranges Myofilament Proteins in Atrial Myocytes. J Clin Med 2019; 8:jcm8060881. [PMID: 31226824 PMCID: PMC6617489 DOI: 10.3390/jcm8060881] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2019] [Revised: 06/14/2019] [Accepted: 06/15/2019] [Indexed: 01/16/2023] Open
Abstract
Individuals with metabolic syndrome (MetS) are at high risk for atrial myopathy and atrial fibrillation. Very low-density lipoproteins (VLDLs) of MetS (MetS-VLDLs) are cytotoxic to atrial myocytes in vivo and in vitro. The calcineurin-nuclear factor of activated T-cells (NFAT) pathway, which is regulated by stromal interaction molecule 1 (STIM1)/ calcium release-activated calcium channel protein 1 (Orai1)-mediated store-operated Ca2+ entry (SOCE), is a pivotal mediator of adaptive cardiac hypertrophy. We hypothesized that MetS-VLDLs could affect SOCE and the calcineurin-NFAT pathway. Normal-VLDL and MetS-VLDL samples were isolated from the peripheral blood of healthy volunteers and individuals with MetS. VLDLs were applied to HL-1 atrial myocytes for 18 h and were also injected into wild-type C57BL/6 male mouse tails three times per week for six weeks. After the sarcoplasmic reticulum (SR) Ca2+ store was depleted, SOCE was triggered upon reperfusion with 1.8 mM of Ca2+. SOCE was attenuated by MetS-VLDLs, along with reduced transcriptional and membranous expression of STIM1 (P = 0.025), and enhanced modification of O-GlcNAcylation on STIM1 protein, while Orai1 was unaltered. The nuclear translocation and activity of calcineurin were both reduced (P < 0.05), along with the alteration of myofilament proteins in atrial tissues. These changes were absent in normal-VLDL-treated cells. Our results demonstrated that MetS-VLDLs suppressed SOCE by modulating STIM1 at the transcriptional, translational, and post-translational levels, resulting in the inhibition of the calcineurin-NFAT pathway, which resulted in the alteration of myofilament protein expression and sarcomere derangement in atrial tissues. These findings may help explain atrial myopathy in MetS. We suggest a therapeutic target on VLDLs to prevent atrial fibrillation, especially for individuals with MetS.

Abstract
BACKGROUND Hemodynamic load leads to cardiac hypertrophy and heart failure. While afterload (pressure overload) induces concentric hypertrophy, elevation of preload (volume overload) yields eccentric hypertrophy and is associated with a better outcome. Here we analysed the proteomic pattern of mice subjected to short-term preload. METHODS AND RESULTS Female FVB/N mice were subjected to aortocaval shunt-induced volume overload that leads to an eccentric hypertrophy (left ventricular weight/tibia length +31 %) with sustained systolic heart function at 1 week after operation. Two-dimensional gel electrophoresis (2-DE) followed by mass spectrometric analysis showed alteration in the expression of 25 protein spots representing 21 different proteins. 64 % of these protein spots were up-regulated and 36 % of the protein spots were consistently down-regulated. Interestingly, α-1-antitrypsin was down-regulated, indicating higher elastin degradation and possibly contributing to the early dilatation. In addition to contractile and mitochondrial proteins, polymerase I and transcript release factor protein (PTRF) was also up-regulated, possibly contributing to the preload-induced signal transduction. CONCLUSIONS Our findings reveal the proteomic changes of early-stage eccentric myocardial remodeling after volume overload. Induced expression of some of the respiratory chain enzymes suggests a metabolic shift towards an oxidative phosphorylation that might contribute to the favorable remodeling seen in early VO. Down-regulation of α-1-antitrypsin might contribute to extracellular matrix remodeling and left ventricular dilatation. We also identified PTRF as a potential signaling regulator of volume overload-induced cardiac hypertrophy.

Abstract
The present study aimed to explore the holistic mechanism for the antihypertrophic effect of a compound in Chinese medicine, QiShenYiQi Pills (QSYQ) and the contributions of its components to the effect in rats with cardiac hypertrophy (CH). After induction of CH by ascending aortic stenosis, rats were treated with QSYQ, each identified active ingredient (astragaloside IV, 3, 4-dihydroxy-phenyl lactic acid or notoginsenoside R1) from its 3 major herb components or dalbergia odorifera, either alone or combinations, for 1 month. QSYQ markedly attenuated CH, as evidenced by echocardiography, morphology and biochemistry. Proteomic analysis and western blot showed that the majority of differentially expressed proteins in the heart of QSYQ-treated rats were associated with energy metabolism or oxidative stress. Each ingredient alone or their combinations exhibited similar effects as QSYQ but to a lesser extent and differently with astragaloside IV and notoginsenoside R1 being more effective for enhancing energy metabolism, 3, 4-dihydroxy-phenyl lactic acid more effective for counteracting oxidative stress while dalbergia odorifera having little effect on the variables evaluated. In conclusion, QSYQ exerts a more potent antihypertrophic effect than any of its ingredients or their combinations, due to the interaction of its active components through a multi-component and multi-target mode.

Abstract
Myocardial hibernation (MH) is a well-known feature of human ischaemic cardiomyopathy (ICM), whereas its presence in human idiopathic dilated cardiomyopathy (DCM) is still controversial. We investigated the histological and molecular features of MH in left ventricle (LV) regions of failing DCM or ICM hearts. We examined failing hearts from DCM (n = 11; 41.9 ± 5.45 years; left ventricle-ejection fraction (LV-EF), 18 ± 3.16%) and ICM patients (n = 12; 58.08 ± 1.7 years; LVEF, 21.5 ± 6.08%) undergoing cardiac transplantation, and normal donor hearts (N, n = 8). LV inter-ventricular septum (IVS) and antero-lateral free wall (FW) were transmurally (i.e. sub-epicardial, mesocardial and sub-endocardial layers) analysed. LV glycogen content was shown to be increased in both DCM and ICM as compared with N hearts (P < 0.001), with a U-shaped transmural distribution (lower values in mesocardium). Capillary density was homogenously reduced in both DCM and ICM as compared with N (P < 0.05 versus N), with a lower decrease independent of the extent of fibrosis in sub-endocardial and sub-epicardial layers of DCM as compared with ICM. HIF1-α and nestin, recognized ischaemic molecular hallmarks, were similarly expressed in DCM-LV and ICM-LV myocardium. The proteomic profile was overlapping by ˜50% in DCM and ICM groups. Morphological and molecular features of MH were detected in end-stage ICM as well as in end-stage DCM LV, despite epicardial coronary artery patency and lower fibrosis in DCM hearts. Unravelling the presence of MH in the absence of coronary stenosis may be helpful to design a novel approach in the clinical management of DCM.

Abstract
The development of heart failure (HF) is characterized by progressive alteration of left ventricle structure and function. Previous works on proteomic analysis in cardiac tissue from patients with HF remain scant. The purpose of our study was to use a proteomic approach to investigate variations in protein expression of left ventricle tissue from patients with ischaemic (ICM) and dilated cardiomyopathy (DCM). Twenty-four explanted human hearts, 12 from patients with ICM and 12 with DCM undergoing cardiac transplantation and six non-diseased donor hearts (CNT) were analysed by 2DE. Proteins of interest were identified by mass spectrometry and validated by Western blotting and immunofluorescence. We encountered 35 differentially regulated spots in the comparison CNT versus ICM, 33 in CNT versus DCM, and 34 in ICM versus DCM. We identified glyceraldehyde 3-phophate dehydrogenase up-regulation in both ICM and DCM, and alpha-crystallin B down-regulation in both ICM and DCM. Heat shock 70 protein 1 was up-regulated only in ICM. Ten of the eleven differentially regulated proteins common to both aetiologies are interconnected as a part of a same network. In summary, we have shown by proteomics analysis that HF is associated with changes in proteins involved in the cellular stress response, respiratory chain and cardiac metabolism. Although we found altered expression of eleven proteins common to both ischaemic and dilated aetiology, we also observed different proteins altered in both groups. Furthermore, we obtained that seven of these eleven proteins are involved in cell death and apoptosis processes, and therefore in HF progression.

BNP controls early load-dependent regulation of SERCA through calcineurin. Basic Res Cardiol 2010; 105:795-804. [PMID: 20711735 PMCID: PMC2965361 DOI: 10.1007/s00395-010-0115-2] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/25/2010] [Revised: 07/20/2010] [Accepted: 08/03/2010] [Indexed: 02/06/2023]
Abstract
Heart failure is characterised by reduced expression of sarcoplasmic reticulum calcium-ATPase (SERCA) and increased expression of B-type natriuretic peptide (BNP). The present study was performed to investigate causality of this inverse relationship under in vivo conditions in the transversal aortic constriction mouse model (TAC). Left ventricular SERCA-mRNA expression was significantly upregulated in TAC by 32% after 6 h, but not different from sham after 24 h. Serum proANP and BNP levels were increased in TAC after 24 h (BNP +274%, p < 0.01; proANP +60%, p < 0.05), but only proANP levels were increased after 6 h (+182%, p < 0.01). cGMP levels were only increased 24 h after TAC (+307%, p < 0.01), but not 6 h after TAC. BNP infusion inhibited the increase in SERCA expression 6 h after TAC. In BNP-receptor-knockout animals (GC-A), the expression of SERCA was still significantly increased 24 h after TAC at the mRNA level by 35% (p < 0.05), as well as at the protein level by 25% (p < 0.05). MCIP expression as an indicator of calcineurin activity was regulated in parallel to SERCA after 6 and 24 h. MCIP-mRNA was increased by 333% 6 h after TAC, but not significantly different from sham after 24 h. In the GC-A-KO mice, MCIP-mRNA was significantly increased in TAC compared to WT after 24 h. In mice with BNP infusion, MCIP was significantly lower 6 h after TAC compared to control animals. In conclusion, mechanical load leads to an upregulation of SERCA expression. This is followed by upregulation of natriuretic peptides with subsequent suppression of SERCA upregulation. Elevated natriuretic peptides may suppress SERCA expression by inhibition of calcineurin activity via activation of GC-A.

Abstract
The identification of new biomarkers is of high interest for the prediction of the disease course and also for the identification of pathomechanisms in multiple sclerosis (MS). To specify markers of the chronic disease phase, we performed proteome profiling during the later phase of myelin oligodendrocyte glycoprotein induced experimental autoimmune encephalomyelitis (MOG-EAE, day 35 after immunization) as a model disease mimicking many aspects of secondary progressive MS. In comparison to healthy controls, high resolution 2 dimensional gel electrophoresis revealed a number of regulated proteins, among them glial fibrilary acidic protein (GFAP). Phase specific up-regulation of GFAP in chronic EAE was confirmed by western blotting and immunohistochemistry. Protein levels of GFAP were also increased in the cerebrospinal fluid of MS patients with specificity for the secondary progressive disease phase. In a next step, proteome profiling of an EAE model with enhanced degenerative mechanisms revealed regulation of alpha-internexin, syntaxin binding protein 1, annexin V and glutamate decarboxylase in the ciliary neurotrophic factor (CNTF) knockout mouse. The identification of these proteins implicate an increased apoptosis and enhanced axonal disintegration and correlate well the described pattern of tissue injury in CNTF −/− mice which involve oligodendrocyte (OL) apoptosis and axonal injury. In summary, our findings underscore the value of proteome analyses as screening method for stage specific biomarkers and for the identification of new culprits for tissue damage in chronic autoimmune demyelination.

Abstract
We performed the present study to determine whether hibernating myocardium is chronically protected from ischemia. Myocardial tissue was rapidly excised from hibernating left anterior descending coronary regions (systolic wall thickening = 2.8 +/- 0.2 vs. 5.4 +/- 0.3 mm in remote myocardium), and high-energy phosphates were quantified by HPLC during simulated ischemia in vitro (37 degrees C). At baseline, ATP (20.1 +/- 1.0 vs. 26.7 +/- 2.1 micromol/g dry wt, P < 0.05), ADP (8.1 +/- 0.4 vs. 10.3 +/- 0.8 micromol/g, P < 0.05), and total adenine nucleotides (31.2 +/- 1.3 vs. 40.1 +/- 2.9 micromol/g, P < 0.05) were depressed compared with normal myocardium, whereas total creatine, creatine phosphate, and ATP-to-ADP ratios were unchanged. During simulated ischemia, there was a marked attenuation of ATP depletion (5.6 +/- 0.9 vs. 13.7 +/- 1.7 micromol/g at 20 min in control, P < 0.05) and mitochondrial respiration [145 +/- 13 vs. 187 +/- 11 ng atoms O(2).mg protein(-1).min(-1) in control (state 3), P < 0.05], whereas lactate accumulation was unaffected. These in vitro changes were accompanied by protection of the hibernating heart from acute stunning during demand-induced ischemia. Thus, despite contractile dysfunction at rest, hibernating myocardium is ischemia tolerant, with reduced mitochondrial respiration and slowing of ATP depletion during simulated ischemia, which may maintain myocyte viability.

Enhancement of the endothelial NO synthase attenuates experimental diastolic heart failure. Basic Res Cardiol 2009; 104:499-509.

Abstract
BACKGROUND Diastolic heart failure is a rising problem with a high incidence and similar mortality and morbidity compared to patients with systolic heart failure. Nevertheless, the underlying pathophysiology is still debated. AIM We investigated the effect of pharmacological enhancement of endothelial nitric oxide synthase (eNOS) on experimental diastolic heart failure (DHF). METHODS DHF was induced in 60 DAHL salt-sensitive rats by salt diet in 8-week-old animals. 30 were treated with the eNOS enhancer AVE3085 (DHFeNOS) and 30 with placebo (DHF). Rats with normal salt intake served as controls. RESULTS AND CONCLUSION Diastolic dysfunction with increased diastolic stiffness constant and increased left ventricular (LV) pressure was analyzed by invasive pressure-volume loop measurements in the DHF group compared to controls. Cardiac hypertrophy as indicated by LV mass measurements by echocardiography, and increased cardiac collagen content as measured by immunohistochemistry were associated with an increased activation state of calcineurin, AKT, ERK(1/2), but not JNK and p38 kinases. Titin isoforms were not altered in this model of DHF. Treatment with AVE3085 significantly increased eNOS mRNA and protein levels in the cardiac tissue and decreases NAD(P)H oxidase subunits p22phox and gp91phox. Diastolic dysfunction was attenuated and cardiac hypertrophy and fibrosis were improved in comparison with untreated DHF animals. This was associated with a normalized activation state of calcineurin, AKT and ERK(1/2). Therefore, we suggest that targeting the NO system might yield a future therapeutic aim for the treatment of DHF.

Abstract
The study of physiological changes occurring during selection contributes to an improved understanding of relationships leading to efficiencies in animal production. To investigate the effects of food restriction in gastrocnemius muscle protein expression, 20% weight reduction was induced in New Zealand White (meat producing) and wild rabbits, using one-dimensional gel electrophoresis and peptide mass fingerprinting. Lower expression levels of myosin heavy chains were found in the Wild Rabbits Restricted Group, while myosin light chain and alpha-crystallin proteins were not detected in restricted groups. Glyceraldeyde-3-phosphate dehydrogenase and glycogen phosphorylase expression levels were similar for all experimental groups. Phosphopyruvate hydratase beta was not detected in the wild rabbit restricted diet group. Pyruvate kinase levels were 50% lower in the New Zealand Restricted group. LIM protein detection was absent in the control New Zealand group. Results also show relevance of actin in preserving muscle structure in depressed food availability, the sensitivity of both myosin light chain and alpha-crystallin protein to restricted feed and the role of PK in the resistance of New Zealand rabbits to food restriction.
