Abstract:Objective To identify the molecular mechanisms underlying ventricular remodeling after myocardial infarction using bioinformatics methods. Methods Microarray data about ventricular remodeling after myocardial infarction were searched from GEO database. Results The array data of GSE47495 were obtained. A total of 611 DEG were identified. Gene ontology analysis showed that the DEG significantly enriched in biological processes, molecular function, and cell component. Pathway analysis showed the DEGs were involved in signaling pathways. The top 3 hub genes, Acox1, Anxa1, and F13a1 were identified from protein-protein interaction network. Results from drug screening indicated that palm oil and curcumin may regulate the above genes. Conclusion During post infarction ventricular remodeling, the identified DEG are mainly enriched in metabolism, extracellular matrix, inflammation, and coagulation. The hub genes, Acox1, Anxa1, and F13a1 provid potential targets for treatment of ventricular remodeling. Palm oil and curcumin may improve the ventricular remodeling through the regulation of these genes.
