For example, CDK4 is amplified in patients with well-differentiated liposarcoma and de-differentiated liposarcoma, hepatocyte growth factor receptor (MET) is overexpressed in de-differentiated liposarcoma, and SRC is activated in myxoid liposarcoma and pleomorphic liposarcoma [12–14]. The gene discussed is MET; the disease is pleomorphic liposarcoma.
