Cross-Species Identification and Validation of Hub Genes and Potential Therapeutic Targets in Myocardial Infarction

Myocardial infarction (MI) is a leading cause of mortality worldwide. Identification of robust and translatable molecular markers remains challenging due to inter-dataset and inter-species variability. In this study, we performed a cross-species integrative analysis to identify conserved hub genes and potential therapeutic targets in MI. Analysis revealed five hub genes (IL6, SERPINE1, MMP14, PLAUR, and ENO1), which were consistently validated across human peripheral blood and multiple animal models. A multigene diagnostic model demonstrated strong predictive performance (AUC = 0.904). The model was developed to distinguish myocardial infarction (MI) samples from non-MI control samples in an independent peripheral blood dataset. Drug-gene interaction analysis identified candidate therapeutic compounds. These results are computational predictions from the DGIdb database and do not represent validated therapeutic effects in myocardial infarction. These findings highlight conserved molecular mechanisms of MI and provide potential biomarkers and therapeutic targets with translational relevance.
