p53 gene expression and 2-methoxyestradiol treatment differentially induce nuclear factor kappa B activation in human lung cancer cells with different p53 phenotypes.

Abstract excerpt

The p53 tumor suppressor gene is frequently mutated in multiple human cancers, leading to loss of wild-type p53 (wt-p53)-dependent functions and tumorigenesis. p53 gene therapy is used to induce apoptosis in human cancer cells and tumors. Activation of nuclear factor kappa B (NF-kappaB) causes resistance to both chemotherapy and apoptosis in tumor cells. We show that expression of wt-p53 from a recombinant...
