About a third of all human cancers, including a high percentage of pancreatic, lung, and colorectal cancers, are driven by mutations in RAS genes. When Ras genes are mutated, cells grow uncontrollably and evade death signals. Ras mutations also make cells resistant to some therapies. This image shows mitochondrial staining (green) and nuclear staining (blue) of human epithelial cells engineered to express oncogenic Ras.
