Lay Summary

Ras is a protein that operates as a molecular switch, toggling between an active “on- state” and an inactive “off-state” in response to growth signals received by the cell. When Ras is in the “on-state” it activates a signaling network that instructs the cell to divide. Unfortunately 15-20% of all human tumors acquire mutations that lock the Ras switch in the “on-state”. Cells with a mutant Ras switch therefore receive a constant signal to undergo cell division, resulting in the outgrowth of a tumor. The major clinical problem is with a form of Ras called K-Ras that is mutated in more than 90% of pancreatic cancers, approximately 50% of colon cancers and 25% of non-small cell lung cancers. ...
