Marker genes shared among Cluster 1, Cluster 2, and Cluster 3 included genes involved in the ribosome (Mrpl13, Mrpl4, Mrpl20, and Mrps18c) and TGF‐β signaling pathway (Hjv, Cul1, and Mapk3), which have been demonstrated to possess anti‐inflammatory effects and promote angiogenesis during myocardial ischemia‐reperfusion [26, 27]. Here, MAPK3 is linked to myocardial ischemia.
