Free Sample Articles from Science Signaling

Many cancers are driven by mutations in the guanosine triphosphatase KRAS; however, mutant KRAS proteins have proven to be extremely difficult to target therapeutically. By bringing together this collection of freely available Research Articles published by Science Signaling, we highlight new potential ways to target mutant KRAS, strategies that preempt the possibility of resistance to such drugs, and the identification of other components in KRAS pathways that could be potential therapeutic targets. If you perform research in this or a related area, we would be very interested in considering your work for publication. Please contact us at:
