Dominance of wild-type p53-mediated transcriptional activation in breast epithelial cells.

Abstract excerpt

The p53 gene is a recessive oncogene whose loss of function can result in cell transformation. Approximately 25% of human breast cancers contain missense mutations in one p53 allele, leading to inactivation of the mutated protein. In almost all of these cases, the wild-type allele is also lost. However, it remains uncertain whether mutant p53 acts in a dominant negative fashion over the wild-type protein. Two...
