MDM2, MDM2-C, and mutant p53 expression influence breast cancer survival in a multiethnic population.


ABSTRACT: PURPOSE:The purpose of the study was to examine the association between expression of mutant p53 (mtp53), full-length MDM2 (MDM2), and MDM2 isoform C (MDM2-C) and survival in multiethnic breast cancer patients. METHODS:A total of 787 invasive breast tumors included in a clinically annotated multiethnic population-based tissue microarray (TMA) were screened utilizing commercially available antibodies to p53 and MDM2, and a newly developed monoclonal antibody recognizing MDM2-C. RESULTS:Mutant p53 (mtp53) was more common in younger (
