Very early on in the development of nonmelanoma cancers p53 is mutated or lost, suggesting that p53 is crucial in protecting normal keratinocytes from the harmful effects of ultraviolet (UV) radiation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective:<\/jats:title>\n                    <jats:p>Using two mouse models, one with multiple copies of mutant p53 and the other a p53 \u201cknockout,\u201d our laboratory has examined a role for p53 in UV-induced DNA damage and determined if these effects are differentiation dependent.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>We outline in this review a proposed model reflecting differentiation-dependent p53 regulation of UV-induced responses in keratinocytes.
