Cortical Bone Derived Stem Cells Modulate Cardiac Fibroblast Response via miR-18a in the Heart After Injury.

Front Cell Dev Biol 2020 23;8:494. Epub 2020 Jun 23.

Independence Blue Cross Cardiovascular Research Center, Lewis Katz School of Medicine, Temple University, Philadelphia, PA, United States.

The adult heart following injury such as a myocardial infarction forms a fibrotic scar associated with transformation of resident cardiac fibroblasts into myofibroblast, accelerating cardiac remodeling and dysfunction. Cell therapies provide a novel direction for the enhancement of cardiac structure and function but remain poorly described in terms of the effect on resident cardiac fibroblasts. We have shown cortical bone derived stem cells (CBSCs) exhibit an ability to repair the heart after myocardial injury together with reduced scar formation. Read More

Evaluating the cardiovascular safety of sclerostin inhibition using evidence from meta-analysis of clinical trials and human genetics.

Sci Transl Med 2020 Jun;12(549)

Big Data Institute at the Li Ka Shing Centre for Health Information and Discovery, University of Oxford, Oxford OX3 7FZ, UK.

Inhibition of sclerostin is a therapeutic approach to lowering fracture risk in patients with osteoporosis. However, data from phase 3 randomized controlled trials (RCTs) of romosozumab, a first-in-class monoclonal antibody that inhibits sclerostin, suggest an imbalance of serious cardiovascular events, and regulatory agencies have issued marketing authorizations with warnings of cardiovascular disease. Here, we meta-analyze published and unpublished cardiovascular outcome trial data of romosozumab and investigate whether genetic variants that mimic therapeutic inhibition of sclerostin are associated with higher risk of cardiovascular disease.

The Clinical Challenge of Clonal Hematopoiesis, a Newly Recognized Cardiovascular Risk Factor.

JAMA Cardiol 2020 May 27. Epub 2020 May 27.

Division of Cardiovascular Medicine, Department of Medicine, Brigham and Women's Hospital, Boston, Massachusetts.

Importance: Despite current standards of cardiovascular care, a considerable residual burden of risk remains in both primary and secondary prevention. Clonal hematopoiesis of indeterminate potential (CHIP) has recently emerged as a common, potent, age-associated, independent risk factor for myocardial infarction, stroke, heart failure events, and survival following percutaneous aortic valve intervention. The presence of CHIP results from the acquisition of somatic mutations in a small number of leukemia driver genes found in bone marrow stem cells, leading to the expansion of leukocytes clones in peripheral blood.

Leukotriene B receptor 1 exacerbates inflammation following myocardial infarction.

FASEB J 2020 Jun 8;34(6):8749-8763. Epub 2020 May 8.

Department of Pharmacology and Toxicology, Graduate School of Pharmaceutical Sciences, Kyushu University, Fukuoka, Japan.

Leukotriene B receptor 1 (BLT1), a high-affinity G-protein-coupled receptor for leukotriene B4 (LTB ), is expressed on various inflammatory cells and plays critical roles in several inflammatory diseases. In myocardial infarction (MI), various inflammatory cells are known to be recruited to the infarcted area, but the function of BLT1 in MI is poorly understood. Here, we investigated the role of BLT1 in MI and the therapeutic effect of a BLT1 antagonist, ONO-4057, on MI. Read More

Management of Hypothyroidism in Patients with Acute Myocardial Infarction.

Medicina (Kaunas) 2020 Apr 28;56(5). Epub 2020 Apr 28.

Division of Endocrinology, Diabetes, & Metabolism, University of Florida, Gainesville, FL 32610, USA.

: Thyroid hormones (TH) affect cardiac function through effects on cardiac contractility and systemic vascular resistance. While TH replacement for patients with hypothyroidism might be necessary for restoration of cardiac output after an acute myocardial infarction (AMI), it could theoretically lead to excessively rapid restoration of the metabolic rate. The appropriate management of hypothyroidism in patients with AMI is unknown. Read More

Disruption of the aldehyde dehydrogenase 2 gene increases the bone anabolic response to intermittent PTH treatment in an ovariectomized mouse model.

Bone 2020 Jul 20;136:115370. Epub 2020 Apr 20.

Department of Orthopaedic Surgery, University of Occupational and Environmental Health, 1-1 Iseigaoka, Yahatanishi-ku, Kitakyushu 807-8555, Japan.

Aldehyde dehydrogenase 2 (ALDH2) is the enzyme that oxidizes the acetaldehyde produced by alcohol metabolism. This variant not only affects the response to alcohol but is also associated with several diseases, such as esophageal cancer, myocardial infarction, and particularly osteoporosis. In our previous study, we reported that compared to wild-type (WT) mice, Aldh2 knockout (KO) mice naturally have a strong bone formation ability, and high expression of parathyroid hormone receptor (PTHR1) in osteocytes.

Mesenchymal Stromal Cell-Derived Small Extracellular Vesicles Induce Ischemic Neuroprotection by Modulating Leukocytes and Specifically Neutrophils.

Stroke 2020 Jun 21;51(6):1825-1834. Epub 2020 Apr 21.

From the Department of Neurology (C.W., M.S., J.S., R.P., N.H., E.D., J.G., C.K., D.M.H.), University Hospital Essen, Germany.

Background and Purpose- Small extracellular vesicles (sEVs) obtained from mesenchymal stromal cells (MSCs) were shown to induce neurological recovery after focal cerebral ischemia in rodents and to reverse postischemic lymphopenia in peripheral blood. Since peripheral blood cells, especially polymorphonuclear neutrophils (PMNs), contribute to ischemic brain injury, we analyzed brain leukocyte responses to sEVs and investigated the role of PMNs in sEV-induced neuroprotection. Methods- Male C57Bl6/j mice were exposed to transient intraluminal middle cerebral artery occlusion. Read More
