Proteins of the Ras pathway as novel potential anticancer therapeutic targets

Abstract:
Ras proteins are molecular switches that constitute a pivotal element in the control of cellular responses to many incoming signals, and in particular mitogenic stimulations. They act through multiple effector pathways that carry out the biological functions of Ras in cells. Since mutations that constitutively activate Ras proteins have been found in a high proportion of human malignancies and participate in oncogenesis, a number of therapeutic anticancer strategies aimed against the activity or action of Ras proteins have been developed. This paper reviews the principal aspects of the Ras signaling pathway and describes some of the attempts to develop antitumor drugs based on this concept.
