Objective: To explore the association between obesity and disease occurrence based on bioinformatics. Methods: The key targets were obtained from the related disease databases (Genecards, TTD, OMIM, Uniprot) with the keywords of “obesity”, “cardiovascular disease”, “heart disease”, “cancer” and “liver metabolic disorder”. Based on the STRING database, the protein-protein interaction network of disease and obesity cross-targets was constructed, the core targets were screened, and the DAVID database was used to analyze the gene ontology function (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways, so as to predict the non-coding RNA and transcription factors acting on the core targets, and construct the gene regulatory network. Results: A total of 25 core targets and 58 interacting miRNAs were screened between obesity and cardiovascular diseases. There were 30 core targets of obesity and heart disease, and 81 interacting miRNAs. There were 25 core targets of obesity and cancer, and 84 interacting miRNAs. There were 30 core targets of obesity and liver metabolic disorders, and 73 interacting miRNAs. The core targets of obesity and cardiovascular disease are mainly enriched in lipids, atherosclerosis, adenylate-activated protein kinases, the signaling pathway, etc. The core targets of obesity and heart disease are mainly enriched in cholesterol metabolism, lipid atherosclerosis and other signaling pathways. The core targets of obesity and cancer are mainly enriched in adenylate-activated protein kinase and phosphatidylinositol 3-kinase-Akt signaling pathway. The core targets of obesity and liver metabolic disorders are mainly enriched in non-alcoholic fatty liver disease and adipocytokine signaling pathways.
