Abstract
AbstractThe ability to photoreverse pyrimidine dimers in DNA of the South American opossum Monodelphis domestica provides a powerful tool with which to probe the role of pyrimidine dimers in ultraviolet radiation (UVR)‐induced histopathologic changes of the skin of this mammal. We have observed that post‐UVR exposure to photoreactivation light not only reversed pyrimidine dimers in epidermal DNA, but also suppressed the capacity of UVR to induce macroscopic and microscopic changes in the skin of M. domestica.
