Project description:This SuperSeries is composed of the following subset Series: GSE20680: Whole Blood Cell Gene Expression Profiling in Patients with Coronary Artery Disease from the Cathgen Registry GSE20681: Whole Blood Cell Gene Expression Profiling in Patients with Coronary Artery Disease from the PREDICT Trial Refer to individual Series
Project description:Gene expression in peripheral blood is shown sufficient to differentiate patients with metabolic disorders from control. The signatures of metabolic syndrome, coronary artery disease and type 2 diabetes also have significant overlap.
Project description:Gene expression in peripheral blood is shown sufficient to differentiate patients with metabolic disorders from control. The signatures of metabolic syndrome, coronary artery disease and type 2 diabetes also have significant overlap. Microarrays were performed on 35 subjects in the following groups: control (n=9), rheumatoid arthritis (n=6), metabolic syndrome (n= 6), coronary artery disease (n=6) and type 2 diabetes (n=8). Intensity values for each array were normalized to a sum of 10,000.
Project description:We aimed to clarify the possible functional role of hsa_circ_0000563 in coronary artery disease. Therefore, the ChIRP-MS was conducted to explore the interaction between BTBD7_hsa_circ_0000563 and proteins on a genomic scale in human peripheral blood mononuclear cell (PBMC). This project is the raw files of the proteins bound to hsa_circ_0000563 found by ChIRP-MS in PBMC.
Project description:The identification of classic risk factors for coronary artery disease unveiled pathophysiologic mechanisms of atherosclerosis. Among them, inflammation as a systemic process measurable in peripheral blood plays a central role in plaque progression. However, other mechanisms of plaque progression remain to be fully understood. Therefore, this study sought to further investigate systemic correlates of plaque progression by global gene expression in peripheral blood. Microrarray gene expression analysis revealed 93 genes differentially expressed between the groups, of which 23 genes have no known function. Among the remaining 70 genes, 10 (14%) were identified to be associated with progenitor and pluripotent cells whereas only 3 genes (4%) had been associated with atherosclerosis. A risk prediction gene signature was developed by a multivariable statistical approach model integrating comprehensive laboratory and clinical patient data. This signature identified plaque progression with 81% sensitivity and 80% specificity (AUC: 0.86) for new patients, as estimated by resampling techniques. Array results were validated by qPCR for the genes ankyrin-2 (ANK2) and glutathione S-transferase theta 1 (GSTT1). In conclusion, patients with pogressive coronary artery disease despite good risk factor control exhibit particular gene expression patterns in peripheral blood. Understanding the functional implications of the observed changes might help to design new approaches to control atherosclerosis progression. From a large database of 45,727 coronary angiograms, peripheral blood was drawn from two patient groups with good risk factor control, but different clinical evolution: First, 16 patients with significant lesion progression leading to repeated coronary interventions and second, 16 patients with angiographically documented stable courses.
Project description:The human LncRNA microarray analysis of the 6 monocytes samples from Coronary Artery Disease patients and non Coronary Artery Disease 3 Coronary Artery Disease patients and 3 non-Coronary Artery Disease donors
Project description:using peripheral blood monocytes to identify marker genes for an extensively grown coronary collateral circulation. We used microarrays to detail the global programme of gene expression underlying collateralization and identified distinct classes of differently regulated genes during this process. Experiment Overall Design: Collateral flow index (CFI) was obtained invasively by angioplasty pressure sensor guidewire, a group of patients with coronary artery disease CAD and a group without CAD were selected for peripheral monocyte isolation, RNA extraction and hybridization on Affymetrix microarrays.
