Previous in vitro studies have shown that oxidized low-density lipoprotein (ox-LDL) plays a role in the pathogenesis of osteoarthritis (OA). Paraoxonase-1 (PON1) protects both low-density lipoproteins (LDLs) and high-density lipoprotein (HDLs) against oxidative damage from circulating cells. In addition, PON1 is inactivated by ox-LDL and preserved by antioxidants. However, the relationship between serum ox-LDL, oxidative stress, and PON1 in knee OA remains unclear. Therefore, we investigated ox-LDL association with oxidative stress and PON1 in knee OA, and evaluated their relationships using radiological and clinical parameters...

Salvia miltiorrhiza, known as Danshen, has attracted worldwide interest for its substantial effects on coronary heart disease (CHD). Danshensu (DSS) is one of the main active ingredients of Danshen on CHD. Although it has been proven to have a good clinical effect on CHD, the action mechanisms remain elusive. In the current study, a coexpression network-based approach was used to illustrate the beneficial properties of DSS in the context of CHD. By integrating the gene expression profile data and protein-protein interactions (PPIs) data, two coexpression protein interaction networks (CePIN) in a CHD state (CHD CePIN) and a non-CHD state (non-CHD CePIN) were generated...

Human induced pluripotent stem cells (iPSCs) can be differentiated into vascular endothelial (iEC) and smooth muscle (iSMC) cells. However, because iECs and iSMCs are not derived from an intact blood vessel, they represent an immature phenotype. Hemodynamics and heterotypic cell:cell communication play important roles in vascular cell phenotypic modulation. Here we tested the hypothesis that hemodynamic exposure of iECs in coculture with iSMCs induces an in vivo-like phenotype. iECs and iSMCs were cocultured under vascular region-specific blood flow hemodynamics, and compared to hemodynamic cocultures of blood vessel-derived endothelial (pEC) and smooth muscle (pSMC) cells...

BACKGROUND: Both oxidative stress markers and inflammatory markers are important when diagnosing depression. Oxidative stress occurs due to an imbalance between free radical generation and antioxidant potential. Both adenosine triphosphate and reactive oxygen/nitrogen species are released during oxidative phosphorylation. When neuroinflammation and free radical production are increased, oxidative stress occurs and causes damage to all major cellular macromolecules. The aim of the study was to compare the concentrations of paraoxonase-1 (PON-1), glutathione reductase (GR), interleukin-18 (IL-18), and oxidized low-density lipoproteins (OxLDL) in depressed patients with and without posttraumatic stress disorder (PTSD), and PTSD alone...

Atherosclerosis is an inflammatory disease regulated by several immune cells including lymphocytes, macrophages and dendritic cells. Gut probiotic bacteria like Lactobacilli have been shown immunomodificatory effects in the progression of atherogenesis. Some Lactobacillus stains can upregulate the activity of regulatory T-lymphocytes, suppress T-lymphocyte helper (Th) cells Th1, Th17, alter the Th1/Th2 ratio, influence the subsets ratio of M1/M2 macrophages, inhibit foam cell formation by suppressing macrophage phagocytosis of oxidized low-density lipoprotein, block the activation of the immune system with dendritic cells, which are expected to suppress the atherosclerosis-related inflammation...

Nitric oxide is an important antiatherosclerotic agent. The main determinant of nitric oxide levels is enzyme nitric oxide synthase encoded by the NOS3 gene, the common variants in this gene may be responsible for variations in plasma enzyme levels. The association of NOS3 variants with coronary artery disease (CAD) varies in different ethnicities. The current study aimed to determine the association of NOS3 Glu298Asp (rs1799983) with CAD and blood lipid levels in Pakistani subjects. Six hundred thirty-six samples (412 cases, 224 controls) were genotyped by TaqMan allelic discrimination assay and serum total cholesterol, and High Density Lipoprotein cholesterol (HDL-C)/Low Density Lipoprotein cholesterol (LDL-C) and triglycerides were measured...

Docosahexaenoic acid (DHA) is present in high concentrations in salmon, herring, and trout. Epidemiologic studies have shown that high dietary consumption of these and other oily fish is associated with reduced rates of myocardial infarction, atherosclerosis, and other ischemic pathologies. Atherosclerosis is induced by inflammation and can lead to acute cardiovascular events and extensive plaque. DHA inhibits the development of inflammation in endothelial cells, alters the function and regulation of vascular biomarkers, and reduces cardiovascular risk...

Atherosclerosis-related cardiovascular disease is the predominant cause of death worldwide. Ox-LDL-induced vascular endothelial cell injury is a major factor in the pathogenesis of atherosclerosis. Dihydromyricetin (DMY) is a flavonoid extracted from vine tea that exerts multiple pharmacological activities, including cardio-protective, anti-tumor, and anti-oxidative effects. However, it is unreported that DMY shows protective effects on ox-LDL-induced endothelial cell injury. In this study, we used an ox-LDL injured human umbilical vein endothelial cell (HUVEC) in vitro model to explore the protective effects and mechanism of DMY...

Lipoprotein(a) Lp(a) is a cholesterol-rich, LDL-like particle that is independently associated with an increased risk for ischemic heart disease, atherosclerosis, thrombosis, and stroke. Genetic variation in the Lp(a) locus and some other genes related to Lp(a) synthesis and metabolism play a critical role in regulating plasma Lp(a) levels. The pathophysiological potential of Lp(a) is related to proatherogenic and prothrombotic effects on the vasculature. Different molecular mechanisms underlying the atherothrombotic potential of Lp(a), free apolipoprotein(a), and oxidized-Lp(a) have been proposed...
