LncRNA Expression Profile and Identification of Novel LncRNA Biomarkers for Diagnosing Coronary Artery Disease


ABSTRACT: Dysregulation of long non-coding RNAs (lncRNAs) has been proven to be involved in the pathogenesis of coronary artery disease (CAD). However, it remains to be extensively explored.Using microarray, we performed the transcriptome-wide lncRNA and mRNAs expression profile in peripheral blood mononuclear cells (PBMCs) of 93 CAD patients and 48 healthy controls. Gene Ontology (GO) and pathway analysis for differentially expressed mRNAs was used to investigate underlying biological associations of differentially expressed lncRNAs and create path-net to depict interactions of significant pathways. We identified 1,210 lncRNAs and 890 mRNAs differentially expressed from the expression profile and validated selected 7 lncRNAs. Two novel lncRNA biomarkers, ENST00000444488.1 and uc010yfd.1, together with CAD risk factors had the better predictive performance for discriminating CAD patients from healthy controls, and ENST00000444488.1 could diagnose acute myocardial infarction (AMI) patients from non-AMI patients.
