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]. The gene discussed is MRPL4; the disease is myocardial ischemia.
