Abstract
To discover new multifunctional agents for the treatment of cardiovascular diseases, we designed and synthesized a series of compounds with a cyclopropyl alcohol moiety and evaluated them in biochemical assays. Biological screening identified derivatives with dual activity: preventing Ca2+ leak through ryanodine receptor 2 (RyR2) and enhancing cardiac sarco-endoplasmic reticulum (SR) Ca2+ load by activation of Ca2+-dependent ATPase 2a (SERCA2a). The compounds that stabilize RyR2 at micro- and nanomolar concentrations are either structurally related to RyR-stabilizing drugs or Rycals or have structures similar to them. The novel compounds also demonstrate a good ability to increase ATP hydrolysis mediated by SERCA2a activity in cardiac microsomes, e.g., the half-maximal effective concentration (EC50) was as low as 383 nM for compound 12a, which is 1,4-benzothiazepine with two cyclopropanol groups. Our findings indicate that these derivatives can be considered as new lead compounds to improve cardiac function in heart failure.

Abstract
Angiotensin-(1-9) is a peptide from the noncanonical renin-angiotensin system with anti-hypertrophic effects in cardiomyocytes via an unknown mechanism. In the present study we aimed to elucidate it, basing us initially on previous work from our group and colleagues who proved a relationship between disturbances in mitochondrial morphology and calcium handling, associated with the setting of cardiac hypertrophy. Our first finding was that angiotensin-(1-9) can induce mitochondrial fusion through DRP1 phosphorylation. Secondly, angiotensin-(1-9) blocked mitochondrial fission and intracellular calcium dysregulation in a model of norepinephrine-induced cardiomyocyte hypertrophy, preventing the activation of the calcineurin/NFAT signaling pathway. To further investigate angiotensin-(1-9) anti-hypertrophic mechanism, we performed RNA-seq studies, identifying the upregulation of miR-129 under angiotensin-(1-9) treatment. miR-129 decreased the transcript levels of the protein kinase A inhibitor (PKIA), resulting in the activation of the protein kinase A (PKA) signaling pathway. Finally, we showed that PKA activity is necessary for the effects of angiotensin-(1-9) over mitochondrial dynamics, calcium handling and its anti-hypertrophic effects.

Abstract
Background Cardiac fibrosis occurs because of disruption of the extracellular matrix network leading to myocardial dysfunction. Angiotensin II (AngII) has been implicated in the development of cardiac fibrosis. Recently, microRNAs have been identified as an attractive target for therapeutic intervention in cardiac pathologies; however, the underlying mechanism of microRNAs in cardiac fibrosis remains unclear. Next‐generation sequencing analysis identified a novel characterized microRNA, miR‐1954, that was significantly reduced in AngII‐infused mice. The finding led us to hypothesize that deficiency of miR‐1954 triggers cardiac fibrosis. Methods and Results A transgenic mouse was created using α‐MHC (α‐myosin heavy chain) promoter and was challenged with AngII infusion. AngII induced cardiac hypertrophy and remodeling. The in vivo overexpression of miR‐1954 showed significant reduction in cardiac mass and blood pressure in AngII‐infused mice. Further analysis showed significant reduction in cardiac fibrotic genes, hypertrophy marker genes, and an inflammatory gene and restoration of a calcium‐regulated gene (Atp2a2 [ATPase sarcoplasmic/endoplasmic reticulum Ca2+ transporting 2]; also known as SERCA2), but no changes were observed in apoptotic genes. THBS1 (thrombospondin 1) is indicated as a target gene for miR‐1954. Conclusions Our findings provide evidence, for the first time, that miR‐1954 plays a critical role in cardiac fibrosis by targeting THBS1. We conclude that promoting the level of miR‐1954 would be a promising strategy for the treatment of cardiac fibrosis.

Dysregulation of the calcium handling protein, CCDC47, is associated with diabetic cardiomyopathy. Cell Biosci 2018; 8:45.

Abstract
Background Diabetes mellitus is associated with an increased risk in diabetic cardiomyopathy (DCM) that is distinctly not attributed to co-morbidities with other vasculature diseases. To date, while dysregulation of calcium handling is a key hallmark in cardiomyopathy, studies have been inconsistent in the types of alterations involved. In this study human cardiomyocytes were exposed to an environmental nutritional perturbation of high glucose, fatty acids, and l-carnitine to model DCM and iTRAQ-coupled LC–MS/MS proteomic analysis was used to capture proteins affected by the perturbation. The proteins captured were then compared to proteins currently annotated in the cardiovascular disease (CVD) gene ontology (GO) database to identify proteins not previously described as being related to CVD. Subsequently, GO analysis for calcium regulating proteins and endoplasmic/sarcoplasmic reticulum (ER/SR) associated proteins was carried out. Results Here, we identified CCDC47 (calumin) as a unique calcium regulating protein altered in our in vitro nutritional perturbation model. The cellular and functional role of CCDC47 was then assessed in rat cardiomyocytes. In rat H9C2 myocytes, overexpression of CCDC47 resulted in increase in ionomycin-induced calcium release and reuptake. Of interest, in a diet-induced obese (DIO) rat model of DCM, CCDC47 mRNA expression was increased in the atrium and ventricle of the heart, but CCDC47 protein expression was significantly increased only in the atrium of DIO rats compared to lean control rats. Notably, no changes in ANP, BNP, or β-MHC were observed between DIO rats and lean control rats. Conclusions Together, our in vitro and in vivo studies demonstrate that CCDC47 is a unique calcium regulating protein that is associated with early onset hypertrophic cardiomyopathy.

Trimetazidine protects cardiomyocytes against hypoxia-induced injury through ameliorates calcium homeostasis. Chem Biol Interact 2015; 236:47-56.

Abstract
Intracellular calcium (Ca(2+)i) overload induced by chronic hypoxia alters Ca(2+)i homeostasis, which plays an important role on mediating myocardial injury. We tested the hypothesis that treatment with trimetazidine (TMZ) would improve Ca(2+)i handling in hypoxic myocardial injury. Cardiomyocytes isolated from neonatal Sprague-Dawley rats were exposed to chronic hypoxia (1% O2, 5% CO2, 37 °C). Intracellular calcium concentration ([Ca(2+)]i) was measured with Fura-2/AM. Perfusion of cardiomyocytes with a high concentration of caffeine (10 mM) was carried out to verify the function of the cardiac Na(+)/Ca(2+) exchanger (NCX) and the activity of sarco(endo)-plasmic reticulum Ca(2+)-ATPase (SERCA2a). For TMZ-treated cardiomyocytes exposured in hypoxia, we observed a decrease in mRNA expression of proapoptotic Bax, caspase-3 activation and enhanced expression of anti-apoptotic Bcl-2. The cardiomyocyte hypertrophy were also alleviated in hypoxic cardiomyocyte treated with TMZ. Moreover, we found that TMZ treatment cardiomyocytes enhanced "metabolic shift" from lipid oxidation to glucose oxidation. Compared with hypoxic cardiomyocyte, the diastolic [Ca(2+)]i was decreased, the amplitude of Ca(2+)i oscillations and sarcoplasmic reticulum Ca(2+) load were recovered, the activities of ryanodine receptor 2 (RyR2), NCX and SERCA2a were increased in cardiomyocytes treated with TMZ. TMZ attenuated abnormal changes of RyR2 and SERCA2a genes in hypoxic cardiomyocytes. In addition, cholinergic signaling are involved in hypoxic stress and the cardioprotective effects of TMZ. These results suggest that TMZ ameliorates Ca(2+)i homeostasis through switch of lipid to glucose metabolism, thereby producing the cardioprotective effect and reduction in hypoxic cardiomyocytes damage.
