Mutant p53 Enhances Nuclear Factor κB Activation by Tumor Necrosis Factor α in Cancer Cells

Abstract excerpt

Mutations in the p53 tumor suppressor are very frequent in human cancer. Often, such mutations lead to the constitutive overproduction of mutant p53 proteins, which may exert a cancer-promoting gain of function. We now report that cancer-associated mutant p53 can augment the induction of nuclear factor kappaB (NFkappaB) transcriptional activity in response to the cytokine tumor necrosis factor alpha (TNFalpha)....
