| Abstract: | Our recent findings on Rheb and eIF4E address key questions of translational control in cancer and have implications for tumor therapy. 1 Briefly, we find that Rheb a proximal activator of mTORC1 and protein translation can cooperate with c-Myc in tumorigenesis in vivo in a manner resembling Akt or the oncogenic eIF4E translation initiation factor. Rheb is highly expressed in some human lymphomas as well as other cancers and likely contributes to malignancies in different tissues.2 The cancer-relevant activities emanating from increased Rheb depend on activation of mTORC1 and are sensitive to rapamycin. Moreover, farnesyltransferase inhibitors (FTIs) can directly block Rheb activity and this is responsible for the therapeutic effect of these drugs in certain tumors. We will discuss here how translational control mechanisms contribute to oncogenesis and speculate on the potential and limitations of targeting these co-operating oncogenic events for therapy. ©2008 Landes Bioscience. |
