Regulation of p53 protein expression in human breast cancer cell lines.

Abstract excerpt

Mutation of the p53 gene is a common occurrence in human breast cancers but is by no means universal. However, even in tumours where the gene is not mutated altered levels of p53 protein are often detected. This is also observed in cell lines derived from human breast cancers. By transfecting such cell lines containing either wild type or mutant p53 genes with a temperature-sensitive mutant mouse p53 gene we have...
