Project description:Despite a significant progress in the treatment of Acute Respiratory Distress Syndrome (ARDS), our ability to identify early patients and predict outcome remains limited. In this study, we aimed to characterize small RNA content of plasma exosomes from ARDS patients in order to identify potential diagnostic biomarkers of the disease. For the first time, we profiled miRNA expression levels in plasma-derived exosomes from ARDS patients (n=8) compared to healthy subjects (n=10) by small RNA-seq. It allowed us to identify 12 exosomal miRNAs differentially expressed in ARDS context (padj<0.05).
Project description:We aimed to identify endotypes of pediatric acute respiratory distress syndrome (ARDS) using whole blood transcriptomics collected within 24 hours of Berlin ARDS onset in intubated children from CHOP Affy microarray and cluster analysis
Project description:The Acute Respiratory Distress Syndrome (ARDS)/Acute Lung Injury (ALI) was described 30 years ago, yet the interaction between specific sets of genes involved in this syndrome remains incompletely understood. Keywords: disease state analysis
Project description:Acute respiratory distress syndrome (ARDS) remains a common and devastating syndrome. CircRNAs are crucial in a variety of diseases and can provide new potential diagnostic and therapeutic targets for disease. The development of circular RNA (circRNA) microarray has facilitated the study of the role of circRNAs in regulating gene expression. This research was designed to explore the expression profile of circRNAs in lung tissues from rats with lipopolysaccharide-induced ARDS. Our findings indicate that the expression profiles of circRNAs has changed in ARDS as compared with normal rat lung tissue, and may provide novel insight into the molecular mechanism underlying the disease and potential novel diagnostic or therapeutic targets for ARDS.
Project description:The Acute Respiratory Distress Syndrome (ARDS)/Acute Lung Injury (ALI) was described 30 years ago, yet the interaction between specific sets of genes involved in this syndrome remains incompletely understood. Experiment Overall Design: 13 patients with ALI + sepsis and 21 patients with sepsis alone were recruited from the Medical Intensive Care Unit of the University of Pittsburgh Medical Center between February 2005 and June 2007. Whole blood was obtained from each patient within 48 hours of admission, and RNA was extracted for gene expression profiling, and comparison analysis.
Project description:Acute respiratory distress syndrome (ARDS) is an acute inflammatory lung injury and one of the serious life-threatening forms of respiratory failure. Alveolar procoagulation and fibrinolytic inhibition constitute the core part of the pathophysiology of ARDS, RUNX1 plays an important role in this pathogenesis. We screened for AKT3, the target gene of RUNX1, using CHIP-seq and verified its binding target by a dual luciferase assay.
