Discovery offers insight for development of cancer therapies targeting mutant p53

Vanderbilt researchers have discovered that aneuploidy (an abnormal number of chromosomes) drives malignant phenotypes in cells expressing mutant p53, a tumor suppressor protein that is mutated in more than half of all human cancers.
