Recapitulating atherogenic flow disturbances and vascular inflammation in a perfusable 3D stenosis model.

Biofabrication 2020 Jul 10. Epub 2020 Jul 10.

Nanyang Technological University, Singapore, SINGAPORE.

Blood vessel narrowing and arterial occlusion are pathological hallmarks of atherosclerosis, which involves a complex interplay of perturbed hemodynamics, endothelial dysfunction and inflammatory cascade. Herein, we report a novel circular microfluidic stenosis model that recapitulates atherogenic flow-mediated endothelial dysfunction and blood-endothelial cell (EC) interactions in vitro. 2D and 3D stenosis microchannels with different constriction geometries were fabricated using 3D printing to study flow disturbances under varying severity of occlusion and wall shear stresses (100 to 2000 dynecm-2).

Investigation of HMG-CoA reductase inhibitory and antioxidant effects of various hydroxycoumarin derivatives.

Arch Pharm (Weinheim) 2020 Jul 10:e1900378. Epub 2020 Jul 10.

Department of Chemistry, Faculty of Arts and Sciences, Marmara University, Istanbul, Turkey.

Cardiovascular diseases are one of the primary causes of deaths worldwide, and the development of atherosclerosis is closely related to hypercholesterolemia. As the reduction of the low-density lipoprotein cholesterol level is critical for treating these diseases, the inhibition of 3-hydroxy-3-methyl-glutaryl coenzyme A (HMG-CoA) reductase, which is essentially responsible for cholesterol biosynthesis, stands out as a key solution to lower plasma cholesterol levels. In this study, we synthesized several dihydroxycoumarins and investigated their antioxidant and in vitro HMG-CoA reductase inhibitory effects. Read More

A Dipeptidyl Peptidase-4 Inhibitor Inhibits Foam Cell Formation of Macrophages in Type 1 Diabetes via Suppression of CD36 and ACAT-1 Expression.

Int J Mol Sci 2020 Jul 7;21(13). Epub 2020 Jul 7.

Department of Medicine, Division of Diabetes, Metabolism, and Endocrinology, Showa University School of Medicine, Tokyo 142-8666, Japan.

Dipeptidyl peptidase-4 (DPP-4) inhibitors have been reported to play a protective role against atherosclerosis in both animal models and patients with type 2 diabetes (T2D). However, since T2D is associated with dyslipidemia, hypertension and insulin resistance, part of which are ameliorated by DPP-4 inhibitors, it remains unclear whether DPP-4 inhibitors could have anti-atherosclerotic properties directly by attenuating the harmful effects of hyperglycemia. Therefore, we examined whether a DPP-4 inhibitor, teneligliptin, could suppress oxidized low-density lipoprotein (ox-LDL) uptake, foam cell formation, and acyl-coenzyme A: cholesterol acyltransferase-1 () gene expression of macrophages isolated from streptozotocin-induced type 1 diabetes (T1D) mice and T1D patients as well as advanced glycation end product (AGE)-exposed mouse peritoneal macrophages and THP-1 cells.

Clonal Hematopoiesis of Indeterminate Potential and Cardiovascular Disease.

Curr Oncol Rep 2020 Jul 9;22(9):87. Epub 2020 Jul 9.

Division of Hematology and Oncology, Mayo Clinic, Rochester, MN, USA.

Purpose Of Review: The purpose of this review article is to summarize the preclinical and clinical evidence supporting the notion of clonal hematopoiesis of indeterminate potential (CHIP), highlight current knowledge gap, and provide future directions.

Recent Findings: Epidemiological studies show that advanced age is a major risk factor for the development of cardiovascular disease (CVD) and cancer, the two leading causes of morbidity and mortality worldwide. While the negative effect of aging on CVD is a reflection of cumulative exposure to various established traditional CVD risk factors, genetic sequencing of whole blood-derived DNA recently revealed that clonal mutations in myeloid stem cells are associated with higher risks of cardiovascular events and hematopoietic malignancies.
