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:Acute Respiratory Distress Syndrome (ARDS) continues to have a high mortality. The objective of this study is to understand the differences in disease biology between survivors and non-survivors by characterizing BALF protein expression profiles in individual ARDS subjects.
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:Whole transcriptomic analysis in rat Acute Respiratory Distress Syndrome (ARDS)
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:MicroRNA (miRNA) control gene transcription by binding to and repressing the translation of messenger RNA (mRNA). Their role in the acute respiratory distress syndrome (ARDS) is undefined. Blood leukocytes from 51 patients enrolled in a prior randomized trial of corticosteroids for ARDS were analyzed. After screening eight patients with microarrays for increased miRNA expression, 25 miRNAs were selected for further analysis using RT-PCR in all 51 patients on days 0, 3 and 7.
