title: A new verdict for an old convict.
abstract: Certain human cancers and carcinogen-induced rodent tumors commonly contain Kras2 mutations. This activated form of ras has always been described as a dominant oncogene. A new study indicates that wildtype Kras2 has properties of a tumor suppressor gene and may have the capacity to reduce the transforming potential of oncogenically activated ras.
