Quantitative Polymerase Chain Reaction of Four Genes in Coronary Artery Disease, Myocardial Infarction and Ischemic Cardiomyopathy
Quantitative Polymerase Chain Reaction of Four Genes in Coronary Artery Disease, Myocardial Infarction and Ischemic Cardiomyopathy
Background:Ischemic heart disease is one of the heaviest health-related burdens worldwide.We aimed to identify the common hub mRNA and pathways that are involved in pathological progression of ischemic cardiomyopathy. Methods: To explore potential differentially expressed genes (DEGs) of all ischemic heart disease stages, we used chipster and GEO2R tools to analyze of retrieved eight high throughput RNA datasets obtained from GEO database. Gene Ontology functional annotation and Pathways enrichment analyses were used to obtain the common functional enriched DEGs which were visualized in protein-protein interactions (PPI) network to explore the hub mRNA according to the interaction scores. Validation qRT-PCR was carried out for blood and cardiac biopsies compared with controls to validate the determined four hub mRNAs and subsequently reviewed inside comprehensive published meta-analysis database. The validated mRNAs were visualized in two interaction modules. Finally screening of approved drugs was applied.
Inclusion criteria The enrolled patients aged 20-80 years with stable coronary artery disease undergoing elective PCI or patients with unstable angina or myocardial infarction undergoing rescue PCI and admitted to the cardiology hospital (Asyut University, Asyut, Egypt) were recruited in this study.
Exclusion criteria Patients with dilated cardiomyopathy were execluded from this study.
