Non-inferiority of microencapsulated mesenchymal stem cells to free cells in cardiac repair after myocardial infarction: A rationale for using paracrine factor(s) instead of cells.

Int J Exp Pathol 2019 Apr 24. Epub 2019 Apr 24.

ITMO University, St. Petersburg, Russia.

A major translational barrier to the use of stem cell (SC)-based therapy in patients with myocardial infarction (MI) is the lack of a clear understanding of the mechanism(s) underlying the cardioprotective effect of SCs. Numerous paracrine factors from SCs may account for reduction in infarct size, but myocardial salvage associated with transdifferentiation of SCs into vascular cells as well as cardiomyocyte-like cells may be involved too. In this study, bone marrow-derived rat mesenchymal SC (MSCs) were microencapsulated in alginate preventing viable cell release while supporting their secretory phenotype. Read More

The effects of parathyroid hormone-related peptide on cardiac angiogenesis, apoptosis, and function in mice with myocardial infarction.

J Cell Biochem 2019 Apr 17. Epub 2019 Apr 17.

Department of Cardiology, The First Affiliated Hospital of Nanjing Medical University, Nanjing, China.

It is known that parathyroid hormone-related peptide (PTHrP) contains a nuclear localization sequence (NLS, 87-107), which, together with its C-terminus (107-139), has been shown to positively regulate vascular smooth muscle cell (VSMCs) proliferation and vascular neointima formation, and inhibit cellular apoptosis. The role of PTHrP in ischemic cardiac diseases remains unclear. In this study, we attempted to determine whether PTHrP 87 to 139 can play a role in promoting cardiac function via enhancing angiogenesis after myocardial infarction (MI) occurred. Read More

Myeloid cell mPges-1 depletion attenuates mortality without affecting remodeling after acute myocardial infarction in mice.

J Pharmacol Exp Ther 2019 Apr 16. Epub 2019 Apr 16.

University of Pennsylvania;

Selective deletion of microsomal PGE2 synthase (mPGES) -1 in myeloid cells retards atherogenesis and suppresses the vascular proliferative response to injury, while it does not predispose to thrombogenesis or hypertension. However, studies using bone marrow transplants from irradiated mice suggest that myeloid cell mPGES-1 facilitates cardiac remodeling and prolongs survival after experimental myocardial infarction (MI). Here we addressed this question using mice lacking mPges-1 in myeloid cells, particularly macrophages (Mac-mPges-1 KO), generated by crossing mPges-1 floxed mice with LysMCre mice, and subjecting them to coronary artery ligation.

Silk fibroin/poly(L-lactic acid-co-ε-caprolactone) electrospun nanofibrous scaffolds exert a protective effect following myocardial infarction.

Exp Ther Med 2019 May 18;17(5):3989-3998. Epub 2019 Mar 18.

Department of Cardiovascular Surgery, Renji Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai 200127, P.R. China.

Electrospinning using biocompatible polymer scaffolds, seeded with or without stem cells, is considered a promising technique for producing fibrous scaffolds with therapeutic possibilities for ischemic heart disease. However, no optimal scaffolds for treating ischemic heart disease have been identified thus far. In the present study, it was evaluated whether electrospun silk fibroin (SF)-blended poly(L-lactic acid-co-ε-caprolactone) [P(LLA-CL)] scaffolds that were seeded with cluster of differentiation 117 (c-kit) bone marrow (BM) cells may serve a protective role in cardiac remodeling following myocardial infarction (MI).

Bortezomib-inducible long non-coding RNA myocardial infarction associated transcript is an oncogene in multiple myeloma that suppresses miR-29b.

Cell Death Dis 2019 Apr 9;10(4):319. Epub 2019 Apr 9.

The Third Xiangya Hospital of Central South University, Changsha, 410013, China.

Clinical outcomes of patients with multiple myeloma (MM) have almost doubled the overall survival over the last decade owing to the use of proteasome inhibitor such as bortezomib (BTZ). However, some patients with MM develop primary resistance to BTZ, whereas others develop resistance after treatment. In this study, we investigated relationships between BTZ resistance and dysfunction of long non-coding RNAs (lncRNAs) in patients with MM. Read More

Calcium and vitamin D supplementation. Myths and realities with regard to cardiovascular risk.

Curr Vasc Pharmacol 2019 Apr 8. Epub 2019 Apr 8.

Dipartimento di Medicina Clinica e Chirurgia, Endocrinology Unit, Federico II University Medical School of Naples. Italy.

Vitamin D and calcium are considered crucial for the treatment of bone diseases. Both vitamin D and calcium contribute to bone homeostasis but also preserve muscle health by reducing the risk of falls and fractures. Low vitamin D concentrations result in secondary hyperparathyroidism and contribute to bone loss, although the development of secondary hyperparathyroidism varies, even in patients with severe vitamin D deficiency.

Comparing Complications and Costs of Total Hip Arthroplasty and Hemiarthroplasty for Femoral Neck Fractures: A Propensity Score-Matched, Population-Based Study.

J Bone Joint Surg Am 2019 Apr;101(7):572-579

Division of Orthopaedic Surgery, Department of Surgery (B.R., D.P., H.K., D.W., R.J., and H.J.K.), and Institute of Health Policy, Management and Evaluation (D.P. and H.J.K.), University of Toronto, Toronto, Ontario, Canada.

Background: Although the prevalence of displaced femoral neck fractures in the elderly population is increasing worldwide, there remains controversy as to whether these injuries should be managed with hemiarthroplasty or total hip arthroplasty. Although total hip arthroplasties result in better function, they are more expensive and may have higher complication rates. Our objective was to compare the complication rates and health-care costs between hemiarthroplasty and total hip arthroplasty for displaced femoral neck fractures in the elderly population.

Supplemental calcium intake in the aging individual: implications on skeletal and cardiovascular health.

Aging Clin Exp Res 2019 Mar 26. Epub 2019 Mar 26.

Division of Endocrinology and Diabetes, Medanta-The Medicity, Gurgaon, New Delhi, India.

Adequate calcium intake during childhood is necessary to achieve optimal peak bone mass and this has the potential by increasing bone reserves, to modulate the rate of age-associated bone loss. However, data regarding the efficacy of calcium obtained either through the diet or in the form of medicinal supplementation, for prevention of bone loss and osteoporotic fractures in the elderly is conflicting. Calcium alone is unlikely to be of benefit for this purpose though the co-administration of calcium and vitamin D may have modest fracture risk benefits. Read More

Neuroimmune crosstalk in the pathophysiology of hypertension.

Nat Rev Cardiol 2019 Mar 20. Epub 2019 Mar 20.

Istituto Auxologico Italiano, IRCCS, Department of Cardiovascular, Neural and Metabolic Sciences, San Luca Hospital, Milan, Italy.

Hypertension is an important risk factor for cardiovascular morbidity and mortality and for events such as myocardial infarction, stroke, heart failure and chronic kidney disease and is a major determinant of disability-adjusted life-years. Despite the importance of hypertension, the pathogenesis of essential hypertension, which involves the complex interaction of several mechanisms, is still poorly understood. Evidence suggests that interplay between bone marrow, microglia and immune mediators underlies the development of arterial hypertension, in particular through mechanisms involving cytokines and peptides, such as neuropeptide Y, substance P, angiotensin II and angiotensin-(1-7).

Toll-like Receptor 7 Deficiency Promotes Survival and Reduces Adverse Left Ventricular Remodeling After Myocardial Infarction.

Cardiovasc Res 2019 Mar 4. Epub 2019 Mar 4.

Department of Surgery, Yong Loo Lin School of Medicine, National University of Singapore, Singapore.

Aims: The Toll-like receptor 7 (TLR7) is an intracellular innate immune receptor activated by nucleic acids shed from dying cells leading to activation of the innate immune system. Since innate immune system activation is involved in the response to myocardial infarction (MI), this study aims to identify if TLR7 is involved in post-MI ischemic injury and adverse remodeling after MI.

Methods And Results: TLR7 involvement in MI was investigated in human tissue from patients with ischemic heart failure, as well as in a mouse model of permanent left anterior descending artery occlusion in C57BL/6J wild type and TLR7 deficient (TLR7-/-) mice. Read More

Circulating myocardial microRNAs from infarcted hearts are carried in exosomes and mobilise bone marrow progenitor cells.

Nat Commun 2019 02 27;10(1):959. Epub 2019 Feb 27.

Department of Biomedical Engineering, University of Alabama at Birmingham, School of Medicine and School of Engineering, 35294, Birmingham, AL, USA.

Myocardial microRNAs (myo-miRs) are released into the circulation after acute myocardial infarction (AMI). How they impact remote organs is however largely unknown. Here we show that circulating myo-miRs are carried in exosomes and mediate functional crosstalk between the ischemic heart and the bone marrow (BM). Read More

Cortical Bone Derived Stem Cells for Cardiac Wound Healing.

Korean Circ J 2019 Apr 24;49(4):314-325. Epub 2019 Jan 24.

Department of Physiology, Cardiovascular Research Center, Lewis Katz School of Medicine, Temple University, Philadelphia, PA, USA.

Ischemic heart disease can lead to myocardial infarction (MI), a major cause of morbidity and mortality worldwide. Adoptive transfer of multiple stem cell types into failing human hearts has demonstrated safety however the beneficial effects in patients with cardiovascular disorders have been modest. Modest improvement in patients with cardiac complications warrants identification of a novel stem cell population that possesses effective reparative properties and improves cardiac function after injury.

Novel role of extracellular matrix protein 1 (ECM1) in cardiac aging and myocardial infarction.

PLoS One 2019 21;14(2):e0212230. Epub 2019 Feb 21.

School of Medicine and Public Health, The University of Newcastle, Callaghan, NSW, Australia.

Introduction: The prevalence of heart failure increases in the aging population and following myocardial infarction (MI), yet the extracellular matrix (ECM) remodeling underpinning the development of aging- and MI-associated cardiac fibrosis remains poorly understood. A link between inflammation and fibrosis in the heart has long been appreciated, but has mechanistically remained undefined. We investigated the expression of a novel protein, extracellular matrix protein 1 (ECM1) in the aging and infarcted heart. Read More

Sequential Bone-Marrow Cell Delivery of VEGFA/S1P Improves Vascularization and Limits Adverse Cardiac Remodeling After Myocardial Infarction in Mice.

Hum Gene Ther 2019 Mar 27. Epub 2019 Mar 27.

1 Vascular Pathophysiology Area, Centro Nacional de Investigaciones Cardiovasculares (CNIC), Madrid, Spain.

Microvascular dysfunction and resulting tissue hypoxia is a major contributor to the pathogenesis and evolution of cardiovascular diseases (CVD). Diverse gene and cell therapies have been proposed to preserve the microvasculature or boost angiogenesis in CVD, with moderate benefit. This study tested in vivo the impact of sequential delivery by bone-marrow (BM) cells of the pro-angiogenic factors vascular endothelial growth factor (VEGFA) and sphingosine-1-phosphate (S1P) in a myocardial infarction model.

Chemokines as Therapeutic Targets in Cardiovascular Disease.

Arterioscler Thromb Vasc Biol 2019 Apr;39(4):583-592

Institute for Cardiovascular Prevention (IPEK), LMU Munich, Germany (C.W., R.R.K.).

With the incidence and impact of atherosclerotic cardiovascular disease and its clinical manifestations still rising, therapeutic options that target the causal mechanisms of this disorder are highly desired. Since the CANTOS trial (Canakinumab Antiinflammatory Thrombosis Outcome Study) has demonstrated that lowering inflammation can be beneficial, focusing on mechanisms underlying inflammation, for example, leukocyte recruitment, is feasible. Being key orchestrators of leukocyte trafficking, chemokines have not lost their attractiveness as therapeutic targets, despite the difficult road to drug approval thus far. Read More

Myocardial infarction induces bone marrow megakaryocyte proliferation, maturation and platelet production.

Biochem Biophys Res Commun 2019 Mar 4;510(3):456-461. Epub 2019 Feb 4.

Department of Cardiology, Zhongnan Hospital of Wuhan University, Wuhan, PR China. Electronic address:

Platelet, apart from its classic role of homeostasis, serves also as a crucial immune cell component that contributes to the aggravation of atherosclerosis. It has been reported that myocardial infarction (MI) triggers leukocytosis in the bone marrow and spleen, which accelerates post-MI atherosclerosis. However, it remains unclear whether thrombopoiesis is also enhanced after MI. Read More
