The IGF‐1 receptor in cancer biology

Abstract
The type 1 insulin‐like growth factor receptor (IGF‐1R) plays an important role in the establishment and maintenance of the transformed phenotype. It also has a strong antiapoptotic activity and has a significant influence on the control of cell and body size. Downregulation of the IGF‐1R leads to massive apoptosis of cancer cells. These characteristics make it an attractive target for anticancer therapy.
