Inhibiting Ras signaling in the therapy of breast cancer.

Abstract

Ras is a small guanosine triphosphate-binding protein that plays an important role in signal transduction pathways that influence cellular proliferation, apoptosis, cytoskeletal organization, and other important biological processes. Prenylation of Ras proteins by the enzyme farnesyltransferase renders the protein hydrophobic, causing localization to the… (More)
