Cells carrying different numbers of copies of wild-type p53 were
transformed by UV irradiation. Putative dense foci were analyzed for their
growth behavior in low serum and for anchorage-independence. A correlation
was found between number of copies of wild-type p53 gene and transformation
frequency: cells with more copies of p53 gene were more resistant to
transformation by UV. The p53 in the transformed clones was shown to be
wild-type at the protein level. A single DNA base change was detected
between GenBank data and our normal and transformed cells; this
pre-existing single base difference is probably due to the differences
between the strains of mice from which the cells were derived.
