Mutant and Wild-type Ras: Co-conspirators in Cancer

Although the functional interplay between mutant and wild-type Ras in driving tumor initiation and growth has been described, a clear picture of the precise ramifications and mechanisms of this association remains elusive, sometimes with conflicting conclusions. A report in this issue of Cancer Discovery tackles this question, which may have important implications for therapeutic strategies to block mutant Ras for cancer treatment. Cancer Discov; 3(1); 24-6.
