mRNA levels of MAPK activated protein kinase 2 (MAPKAPK2) and 3 (MAPKAPK3), protein kinase B β (AKT2), and platelet-derived growth factor receptor β (PDGFRB) decreased significantly, while that of BMX (BMX) increased significantly in the IHD group (Supplementary Table 4). The gene discussed is PDGFRB; the disease is myocardial ischemia.
