Different expression profiles and bioinformatics analysis of circular RNAs between ST-elevation myocardial infarction and chronic artery syndroms.

ABSTRACT: We aimed to confirm the different expression profiles of circular RNAs (circRNAs) between ST-elevation myocardial infarction (STEMI) and chronic coronary syndromes (CCS) and identify the role of circRNAs in STEMI.

Assessment and Diagnostic Relevance of Novel Serum Biomarkers for Early Decision of ST-elevation Myocardial Infarction

Project description:We aim to determine blood transcriptome-based molecular signature of acute coronary syndrome (ACS), and to identify novel serum biomarkers for early stage ST-segment-elevation myocardial infarction (STEMI) We obtained peripheral blood from the patients with ACS who visited emergency department within 4 hours after the onset of chest pain: ST-elevation myocardial infarction (STEMI, n=7), Non-ST-elevation MI (NSTEMI, n=10) and unstable angina (UA, n=9), and normal control (n=7)

Whole blood transcriptional profiling by RNA sequencing in patients with ST-elevation and non-ST elevation myocardial infarction

Project description:Aims. We sought for peripheral blood gene expression signatures at presentation that distinguish the ST elevation (STEMI) and non-ST elevation myocardial infarction (NSTEMI) conditions, to define a precise map of differentially regulated biological processes, unveil new distinctive traits, and help predict markers of outcome. Methods and results. Total RNA from whole blood of STEMI and NSTEMI patients was used to prepare poly(A)+ enriched libraries for paired-end RNA-Seq. Transcriptomes were reconstructed and, after adjustment for unwanted variation, we performed differential expression analysis. Enrichment analyses was performed to infer differentiating functional networks. We identified 153 differentially expressed genes, which stood correction for TnI levels at admission and included 32 putative novel genes (false discovery rate-adjusted P<0.05). We found a divergent modulation of inflammatory, immune-response, angiogenic, and mitochondrial dynamics pathways. Finally, we showed that specific gene expression patterns at admission predict troponin I (TnI) peak levels and/or GRACE risk score. Conclusions. RNA-Seq allowed identifying novel differentially expressed genes in STEMI vs. NSTEMI, which might uncover unappreciated mechanisms underlying acute MI. Overall, our results depicted a scenario characterizing different pathological traits of these two types of acute MI that could pave the way for the identification of novel, specific biomarkers for early diagnosis, risk stratification, and therapeutic decision-making.

Role of differential microRNA 378 expression in increased pro-angiogenic activity of mobilized CD34+ progenitor cells of patients with acute ST-elevation myocardial infarction:

Project description:Rationale: Pro-angiogenic effects of mobilised bone-marrow-derived stem/progenitor cells are essential for cardiac repair after myocardial infarction. MicroRNAs (miRNA/miR) are key regulators of angiogenesis. Objective: To determine the differential regulation of angiomiRs, i.e microRNAs regulating neovascularisation, in mobilised CD34+ progenitor cells obtained from patients with an acute ST-segment elevation myocardial infarction (STEMI) as compared to those with stable coronary artery disease (sCAD) or healthy subjects. Methods and Results: CD34+ progenitor cells were isolated from patients with STEMI (on day 0 and day 5), sCAD and healthy subjects (n=27). CD34+ progenitor cells of patients with STEMI exhibited increased pro-angiogenic activity as compared to CD34+ cells from the other groups. Using a PCR-based miRNA-array and Real-Time PCR validation we identified a profound up-regulation of two known angio-miRs, i.e. miR-378 and let-7b, in CD34+ cells of patients with STEMI. Especially, we demonstrate that miR-378 is a critical regulator of the pro-angiogenic capacity of CD34+ progenitor cells and its stimulatory effects on endothelial cells in-vitro and in-vivo, whereas let-7b up-regulation in CD34+ cells failed to proof its effect on endothelial cells in-vivo. Conclusion: The present study demonstrates for the first time a significant upregulation of the angiomiRs miR-378 and let-7b in mobilised CD34+ progenitor cells of patients with STEMI. The increased pro-angiogenic activity of these cells in patients with STEMI and the observation that in particular miR-378 regulates the angiogenic capacity of CD34+ progenitor cells in-vivo suggest that this unique microRNA expression pattern represents a novel endogenous repair mechanism activated in acute myocardial infarction.

Characterization of the platelet transcriptome by RNA sequencing in patients with acute myocardial infarction.

Project description:Recent technological advances have made transcriptome sequencing (RNA-seq) possible in cells with low RNA copy number including platelets. Resulting studies have used RNA-seq in platelets isolated from healthy individuals to characterize the platelet transcriptome. However, platelets, possibly through gene expression changes, contribute to the etiology of and response to cardiovascular disease and events. To address this, we performed the largest human platelet RNA-seq analysis to date in 34 platelet samples: 16 ST-segment elevation myocardial infarction (STEMI), 16 non-STEMI (NSTEMI), and 2 controls. RNA-seq of platelet samples from 34 individuals: 16 with ST-elevation myocardial infarction (STEMI), 16 with non-STEMI, and 2 non-myocardial infarction controls

Increase in innate lymphoid cells during acute ST-segment elevated myocardial infarction and its clinical relevance

Project description:Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are to use RNA-seq to compare ILC1s gene expression in ST segmment elevation myocardial infarction patient compared with healthy control. Results: Using an optimized data analysis workflow, More than 70 million clean reads were obtained from each sample group after elimination of low-quality reads. A total of 4204 DEGs were found up-regulated and 4712 DEGs down-regulated on comparison of ILC1s from STEMI patients and controls. Conclusion: The dynamic number and gene expression changes in the subtype ILC1s indicate the role of ILCs in STEMI.
