Abstract
Transforming growth factor-β1 (TGF-β1) plays an important role on fibrogenesis in heart disease. MicroRNAs have exhibited as crucial regulators of cardiac homeostasis and remodeling in various heart diseases. MiR-19a-3p/19b-3p expresses with low levels in the plasma of heart failure patients. The purpose of our study is to determine the role of MiR-19a-3p/19b-3p in regulating autophagy-mediated fibrosis of human cardiac fibroblasts. We elucidate our hypothesis in clinical samples and human cardiac fibroblasts (HCF) to provide valuable basic information. TGF-β1 promotes collagen I α2 and fibronectin synthesis in HCF and that is paralleled by autophagic activation in these cells. Pharmacological inhibition of autophagy by 3-methyladenine decreases the fibrotic response, while autophagy induction of rapamycin increases the response. BECN1 knockdown and Atg5 over-expression either inhibits or enhances the fibrotic effect of TGF-β1 in experimental HCF. Furthermore, miR-19a-3p/19b-3p mimics inhibit epithelial mesenchymal transition (EMT) and extracellular matrix (ECM) prodution and invasion of HCF. Functional studies suggest that miR-19a-3p/19b-3p inhibits autophagy of HCF through targeting TGF-β R II mRNA. Moreover, enhancement of autophagy rescues inhibition effect of miR-19a-3p/19b-3p on Smad 2 and Akt phosphorylation through TGF-β R II signaling. Our study uncovers a novel mechanism that miR-19a-3p/19b-3p inhibits autophagy-mediated fibrogenesis by targeting TGF-β R II.

Abstract
BACKGROUND Few studies have reported the effect of aldosterone receptor antagonist (ARA) on myocardial remodeling after acute myocardial infarction (AMI). This study was undertaken to investigate the preventive effect of ARA on myocardial remodeling after AMI. METHODS A total of 616 patients who had been admitted into the CCU of the First Affiliated Hospital of Harbin Medical University from January 2008 to January 2010 were studied prospectively. Only 528 patients were observed completely, including 266 of the control group and 262 of the treatment group. There was no statistical difference in age, gender, medical history, admission situation, and treatment between the two groups (P>0.05). The preventive effects of spironolactone on cardiac remodeling, left ventricular function, renal function and blood levels of potassium were evaluated by echocardiography, serum potassium and serum creatinine at one-month and one-year follow-up. RESULTS The echocardiography indicators such as LVESD, LVEDD, LVEF, LAD-ML and LAD-SI were significantly improved in the treatment group compared with the control group at one year (P<0.05). In the treatment group, LVESD, LVEDD, LVPWT, LVEF, LAD-ML and LAD-SI were more significantly improved at one year than one month (P<0.05, P=0.007 to LVEF), and in the control group LVEF was more significantly improved at one year than one month (P=0.0277). There were no significant differences in serum potassium and serum creatinine levels between the two groups. CONCLUSION On the basis of conventional treatment, the early combination of low-dose spironolactone (20 mg/d) could inhibit cardiac remodeling at late stage and prevent heart failure.

Abstract
Nicotinamide phosphoribosyltransferase (Nampt) is an important coenzyme involved in cellular redox reactions. Inside the cell, Nampt (iNampt) functions as a rate-limiting enzyme in the NAD salvage pathway, and outside the cell (eNampt), it acts as a proinflammatory cytokine. High-circulating levels of Nampt are reported in different pathological conditions. This study was designed to examine the role of Nampt in the development of cardiac hypertrophy and ventricular remodeling. We studied the hypertrophic response in Nampt heterozygous (+/-) knockout and cardiac-specific overexpressing Nampt transgenic mice. Whereas Nampt(+/-) mice were protected against agonist (isoproterenol and angiotensin II)-induced hypertrophy, Nampt transgenic mice spontaneously developed cardiac hypertrophy at 6 mo of age. Experiments conducted to gain insight into the mechanism revealed that treatment of cardiomyocytes with recombinant (eNampt) or overexpression with Nampt-synthesizing adenovirus vector (Ad.Nampt) induced cardiomyocyte hypertrophy. The prohypertrophic effects of eNampt and Ad.Nampt were blocked by the addition of a Nampt-blocking antibody into cultures, thus suggesting that Nampt was in fact invoking hypertrophic response of cardiomyocytes by acting on the cell surface receptors. We also found increased Nampt levels in the supernatant of cardiomyocyte cultures subjected to stress by either serum starvation or H(2)O(2) treatment. Exploration of signaling pathways in Nampt-induced cardiac hypertrophy and fibrosis revealed increased activation of mitogen-activated protein kinases, namely, JNK1, p38, and ERK. This was also associated with increased calcineurin levels and nuclear factor of activated T-cell localization into the nucleus. From these studies we conclude that cardiomyocytes are capable of secreting Nampt during stress, and exogenous Nampt is a positive regulator of cardiac hypertrophy and adverse ventricular remodeling.

Abstract
OBJECTIVES Atrial remodeling is an important part of cardiac remodeling after acute myocardial infarction (AMI). The aim of this study was to evaluate the effect of spironolactone on atria in patients with preserved left ventricular (LV) functions after AMI by using two-dimensional and tissue Doppler imaging techniques (TDI). METHODS The study consisted of 110 patients with AMI, successfully revascularized with percutaneous coronary intervention, ejection fraction greater than or equal to 40%, and Killip class I-II. Patients were randomized into two groups: conventional therapy (n=55) and additional spironolactone of 25 mg/day with standard conventional therapy (n=55). Echocardiography was performed in the first 48-72 h of AMI and during 6 months of follow-up. Left atrial volume index and emptying fraction were obtained. The peak regional atrial contraction velocity, the time between the onset of p-wave on the monitor ECG and the onset, peak, and the end (TE) of the atrial contraction wave on the tissue Doppler technique curve were measured. RESULTS The left atrial volume index and left atrium (LA) dimensions did not significantly change in either group. In the spironolactone group, left atrial emptying fraction increased compared with both baseline value (from 53.0 ± 0.16 to 57.0 ± 0.13 P=0.011) and conventional therapy group (from 50.0 ± 0.17 to 47.0 ± 0.16, P=0.013). The atrial contraction velocity did not change but the LA-TE, interatrial septum-TE, and right atrium-TE were prolonged in the conventional therapy group. CONCLUSION Additional spironolactone therapy provided a little benefit on LA remodeling and atrial electromechanic properties in patients with AMI and preserved LV functions.

Role of healing-specific-matricellular proteins and matrix metalloproteinases in age-related enhanced early remodeling after reperfused STEMI in dogs. Mol Cell Biochem 2008; 322:25-36.

Abstract
We assessed whether aging augments left ventricular (LV) damage, remodeling, and dysfunction and alters expression of healing-specific-matricellular proteins (HSMPs), matrix metalloproteinases (MMPs) and other pertinent proteins after acute reperfused-ST-segment-elevation myocardial infarction (RSTEMI) in the dog model. The findings suggest a novel role for HSMPs, MMPs, and the other proteins in the age-related increase in LV damage, remodeling, and dysfunction. Potentially detrimental effects of the altered proteins appear to outweigh beneficial effects and contribute to adverse outcome. Deleterious changes include the increase in matrix-degrading MMPs, inducible nitric oxide synthase (iNOS) and pro-inflammatory cytokines interleukin (IL)-6 and tumor necrosis factor (TNF)-alpha, HSMPs such as secreted-protein-acidic-and-rich-in-cysteine (SPARC) and osteopontin (OPN), the blunted increase in endothelial-NOS (eNOS), and the decrease in IL-10 and neuronal NOS (nNOS). Potentially beneficial changes include increases in the HSMP secretory-leucocyte-protease-inhibitor (SLPI) and cytokine transforming growth factor (TGF)-beta(1). Targeting these proteins may mitigate enhanced LV remodeling and dysfunction with aging.

Abstract
BACKGROUND Osteoprotegerin (OPG) and receptor activator of nuclear factor kappa-B ligand (RANKL) are critical regulators of bone remodeling and RANKL/RANK signaling could also play an important role in the remodeling process of several tissues, such as myocardium. Therefore, we investigated whether the serum concentrations of OPG and RANKL correlate with the serum levels of metalloproteinase-1 (MMP-1), MMP-9 and tissue inhibitors of MMP-1 (TIMP-1), which are known regulators of myocardial healing in acute myocardial infarction (AMI) patients. METHODS We analyzed blood samples from 51 consecutively hospitalized men with AMI, 12 men with established ischemic heart failure (New York Heart Association category II, NYHA-II) and 12 healthy men age-matched to the NYHA-II patients. Serum levels of MMP-1, MMP-9, TIMP-1, OPG and RANKL were quantified using commercially available ELISA kits. AMI patients were sampled 4 days and 6 months after MI. RESULTS Our data revealed increased serum levels of OPG, RANKL, MMP-1 and TIMP-1 levels and significant correlations between increased RANKL levels and MMP-1 and TIMP-1 serum levels 6 months after MI. In addition, the ratio OPG/RANKL was very low 6 months after MI, suggesting that the nuclear factor kappa-B signaling is possibly more active 6 months post-MI than it is on day 4 post-MI. CONCLUSIONS Our data suggest that OPG, RANKL, MMP-1 and TIMP-1 serum levels can be potential mediators of myocardial healing after MI. However, further large studies are needed to confirm the utility of OPG and RANKL as markers of healing after ST elevation in MI.

Abstract
BACKGROUND In heart failure patients, cardiac resynchronization therapy (CRT) leads to reverse ventricular remodelling. AIM The aim of this study was to evaluate whether changes in levels of circulating biomarkers of extracellular matrix metabolism correlate with the response to CRT. METHODS AND RESULTS Clinical parameters, left ventricular (LV) volumes, and circulating levels of tenascin-C (TNC), matrix metalloproteinase-2 (MMP-2), MMP-9, and amino-terminal propeptide of brain natriuretic peptide (NT-proBNP) were assessed in 64 patients at baseline and 6 months follow-up. The majority of patients (72%) showed a >10% reduction in LV end-systolic volume at follow-up, and were classified as responders to CRT. The remaining patients were classified as non-responders. In responders, a significant decrease in circulating levels of TNC (from 60+/-40 ng/mL to 47+/-30 ng/mL, p<0.01), MMP-9 (from 55+/-30 AU to 44+/-27 AU, p<0.01), and NT-proBNP (from 2106+/-1805 pg/mL to 1132+/-1289 pg/mL, p<0.001) were observed at follow-up; MMP-2 levels were unchanged. In non-responders TNC, NT-proBNP, MMP-9 and MMP-2 levels remained unchanged. CONCLUSION At 6 months follow-up, CRT was associated with reverse LV remodelling, and a significant decrease in TNC, MMP-9, and NT-proBNP levels. This suggests an important role of ECM modulation in the process of reverse ventricular remodelling in patients responding to CRT.
