Effect of xenogenic repair enzymes on photoimmunology and photocarcinogenesis

Stege, Helger·2001·Journal of Photochemistry and Photobiology B: Biology

Abstract

Exposure to ultraviolet B (UVB) radiation leads to an increased generation of UVB-induced skin damage in humans. The most important UVB-induced side effects are UVB-induced immunosuppression and photocarcinogenesis and there is a large body of evidence that cyclobutane pyrimidine dimers (CPD) induced by UVB radiation play a pivotal role in both processes. The topical application of DNA repair enzymes is a new innovative strategy to reduce the amount of CPDs in human skin. Two different methods have recently been established. The use of T4 endonuclease V was of clinical efficacy in protecting patients with a nucleotide excision repair defect from premalignant and malignant skin lesions. Application of photolyase, a xenogenic enzyme which has been found in different organisms is also capable of removing UVB-induced CPD from normal human skin cells in vivo and appears to be more effective than T4 endonuclease V in damage removal. Photolyase encapsulated in liposomes may have in the near future a broad use as an active ingredient in modern skin care products.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
