Abstract:


Hereditary breast cancers affect women who have an increased risk of developing tumors because of a familial history. In most cases, they can be attributed to mutations in the breast cancer associated gene 1 and 2 (BRCA1 and BRCA2). Recent studies have demonstrated a link between the insulin-like growth factor (IGF) signaling pathway and familial breast cancer incidence. IGF and IGF receptors represent a family of biological growth factors and transducers, which have been involved in both physiological and pathological processes. It has been shown that BRCA1 regulates expression of several members of the IGF family. Here, we will examine our understanding of the functions of IGF/IGF-receptor signaling, the development of new inhibitors of this pathway and the related mechanisms of familial breast cancer formation.
