Study in different kinds of cancer mainly focused on the roles of SRC (v-src sarcoma (Schmidt-Ruppin A-2) viral oncogene homolog (avian)), MAPK (mitogen-activated protein kinase), MET (met protooncogene (hepatocyte growth factor receptor)), ATM (ataxia telangiectasia mutated), PDGFRa (platelet-derived growth factor receptor, alpha polypeptide), ErbB (v-erb-a erythroblastic leukemia viral oncogene homolog), MAP2 K1 (bromodomain containing 4), TGFbR1 (transforming growth factor, beta receptor 1), and CDK6 (cyclin-dependent kinase 6) (shown in Figure 1). The gene discussed is ATM; the disease is cancer.
