Plasma exosomes miRNAs high-throughput sequencing in patients after STEMI 3-6 months

Project description:ST-segment elevated myocardial infarction (STEMI) is one of the most severe forms of cardiovascular heart diseases. In the present study, we aim to describe differential expressed plasma exosome-miRNAs in patients with post-STEMI 3-6 months. Methods: Consecutive patients with ages from 40 to 80 years and 25 males among them 3-6 months after STEMI (n=11) were compared to sex-matched healthy control (n=10). The mean age of the patient was 64.71±10.40 years and 89.2% were male. Compared to the healthy control group, the plasma exosome-miRNAs were assessed by using microarray assay (IIIumnia Hiseq 2500). Profile of plasma exosome-miRNAs related to heart diseases was established both in the patient and control groups. The specificity of the lowest expressed exosome-miRNAs for all subjects was evaluated by using a quantitative real-time polymerase chain (qPCR). plasma exosomes miRNAs were obtained from STEMI patients after 3-6 months and healthy subjects

Gene expression profiling reveals potential prognostic biomarkers associated with the progression of heart failure

Project description:Heart failure (HF) is the most common cause of morbidity and mortality in the developed countries, especially considering the present demographic tendencies in those populations. We identified biologically relevant transcripts that are significantly altered in the early phase of myocardial infarction (MI) and are associated with the development of post-myocardial infarction HF. We collected peripheral blood samples from patients (n=111) with ST-segment elevation myocardial infarction (STEMI) at four time points (admission, discharge, 1 month after MI, and 6 months after MI). Control group comprised patients (n=46) with a stable coronary artery disease and without a history of myocardial infarction. Affymetrix HuGene 1.0 ST arrays were used to analyze mRNA levels in periperal blood mononuclear cells (PBMCs) isolated from the study and control groups. Samples from the first three time points were compared with the samples from the same patients collected 6 months after MI (stable phase) and with the control group. Additionaly, based on plasma NT-proBNP level and left ventricular ejection fraction parameters the STEMI patients were divided into HF and non-HF groups.We attempted to identify transcripts whose differential expression on the 1st day of myocardial infarction predicted which patients would develop symptoms of HF during the 6 months of follow-up. For this purpose, we compared the microarray results for samples collected on admission for the HF group versus the non-HF group.

Expression data from blood samples of STEMI and Same STEMI patients after PIC

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: a set of blood samples of patients with STEMI (n=7) before and 7 days after the primary percutaneous coronary intervention (n=7) and normal control (n=10)

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.
