bcl-2 vs p53 Protein Expression and Apoptotic Rate in Human Nonmelanoma Skin Cancers

Abstract

These results indicate that a disturbance in either p53 or bcl-2 suffices to enhance skin tumor formation by suppressing apoptosis; bcl-2 appears to reduce the rate of spontaneous apoptosis, but an aberrant p53 expression does not, and this factor may solely affect the apoptosis from exogenous genotoxicity.
