In a study by senior authors Tyler Jacks and Francisco Sánchez-Rivera, researchers developed a method for easily engineering specific cancer-linked mutations into mouse models. With a CRISPR-based prime editing system installed in the mouse genome, researchers can induce a tumor in a specific tissue, expressing a specific mutation, by injecting an activating protein together with an RNA editing guide. In a Nature Biotechnology study, the researchers created models of several different mutations of the cancer-causing gene Kras, in different organs. They believe this technique could also be used for nearly any other type of cancer mutation that has been identified.
