Targeting the oncogenic Met receptor by antibodies and gene therapy

Abstract

The receptor for hepatocyte growth factor (HGF), a tyrosine kinase encoded by the Met oncogene, has a crucial role in cancer growth, invasion and metastasis. It is a validated therapeutic target for 'personalized' treatment of a number of malignancies. Therapeutic tools prompting selective, robust and highly effective Met inhibition potentially represent a major step in the battle against cancer. Antibodies targeting either Met or its ligand HGF, although challenging, demonstrate to be endowed with promising features. Here we briefly review and discuss the state of the art in the field.
