Integrative Analysis of Key Genes and Signaling Pathways By Bioinformatics in Patients with Type 1 Diabetes Mellitus Combined with Acute Myocardial Infarction

Although the pathogenesis of type 1 diabetes mellitus (T1D) and acute myocardial infarction (AMI) remains unclear. We investigated the key genes and signaling pathways common to T1D and AMI. First, we screened differentially expressed genes (DEGs) co-expressed by T1D and AMI through gene expression synthesis (GEO) database and text mining. David database was used for enrichment and functional analysis of selected genes. The interaction between proteins (PPI) was created using STRING and Cytoscape software. MCODE is used for module analysis of PPI network. A total of 74 human genes that met the criteria were found in T1D and AMI. The first 10 central genes include STAT3, ITGAM, MMP9, ERBB2, MAPK3, FOS, MYD88, MAPK1, TFRC and TNFRSF1A.The establishment of the aforementioned key genes might serve as novel biomarkers for precision diagnosis and providing medical treatment for the occurrence of AMI in T1D patients in the future.
