In a necropsy study, we used immunohistochemistry to explore where and to what extent CCL2 and related receptors are present in diseased arteries that caused the death of men with coronary artery disease compared with unaffected arteries.
Effects of crocin and saffron aqueous extract on gene expression of SIRT1, AMPK, LOX1, NF-κB, and MCP-1 in patients with coronary artery disease: A randomized placebo-controlled clinical trial.
In MCP1rs1024611 SNP analysis, homozygous mutation was significantly more common in the OSAS + CAD group than in the OSAS and control groups (p < 0.001).
After the MCODE analysis, the top 4 high degree genes, including interleukin 1 beta (IL1B, degree = 29), intercellular adhesion molecule 1 (ICAM1, degree = 25), Jun proto-oncogene (JUN, degree = 23) and C-C motif chemokine ligand 2 (CCL2, degree = 20) had been identified to validate in RT-PCR and Cox proportional hazards regression between CAD and normals.
Genetically determined higher MCP-1 levels were further associated with coronary artery disease (OR, 1.04; 95% CI, 1.00-1.08; P=0.04) and myocardial infarction (OR, 1.05; 95% CI, 1.01-1.09; P=0.02), but not with atrial fibrillation.
In this study, we investigated whether RFX1 and epigenetic modifications mediated by RFX1 contribute to the overexpression of MCP1 in activated monocytes in CAD patients.
Treatment of human aortic endothelial cells (HAECs) with MPs isolated from CAD+OSAHS patients markedly increased HAEC permeability (as detected by FITC-dextran), and significantly upregulated mRNA levels of ICAM-1, VCAM-1, and MCP-1.
Comparison of gene expression pattern between CAD and MetS revealed significantly higher expression of leukotriene genes - arachidonate 5-lipoxygenase (ALOX5), arachidonate 5-lipoxygenase activating protein (ALOX5 AP), leukotriene A4 hydrolase (LTA4H) and leukotriene C4 synthase (LTC4S), and lower expression of NF-κB, interleukin 1 beta (IL-1β), monocyte chemoattractant protein-1 (MCP-1/CCL2) and signal transducer and activator of transcription 3 (STAT3) genes in CAD.
The effect of the MCP-1 polymorphisms on various metabolic cardiovascular risk factors and metabolic parameters was explored separately in controls, and premature CAD.
Results of the present study suggests that G-allele of MCP-1 -2518A>G polymorphism is associated with reduced risk of T2D and increased risk of CAD in the population of Punjab.
Compared to controls, there were no associations between circulating levels of IL-8, lipocalin-2, nerve growth factor (NGF), RANTES, CD-163, GPX-3, monocyte chemotactic protein-1 (MCP-1)/CCL2, leptin, soluble vascular endothelial growth factor receptor-1 (sFLT1), fatty acid binding protein-4 (FABP-4), and plasminogen activator inhibitor-1 (PAI-1) and increases in their gene expression in EAT adjacent to CAD.
The results indicate that MCP-1-2518G allele had probably increased risk of CAD in Caucasian but this is likely to be due to publication bias and insufficient sample size.
Interestingly, the mRNA levels of IL-6, IL-1beta, MCP-1, natriuretic peptide receptor-C (NPR-C), adrenomedullin, and leptin in epicardial adipose tissue were higher in patients with CAD than those without CAD.
