  8. Bito T, Sumita N, Masaki T, Shirakawa T, Ueda M, Yoshiki R, et al. Ultraviolet light induces Stat3 activation in human keratinocytes and fibroblasts through reactive oxygen species and DNA damage. Exp Dermatol. 2010;19:654-60 pubmed publisher
    ..The present data suggest that Stat3 activation in UV-exposed human skin is one of the initial events where DNA damage and ROS are involved. ..
  9. Miyamoto I, Miura N, Niwa H, Miyazaki J, Tanaka K. Mutational analysis of the structure and function of the xeroderma pigmentosum group A complementing protein. Identification of essential domains for nuclear localization and DNA excision repair. J Biol Chem. 1992;267:12182-7 pubmed
    ..These results suggest that all 4 cysteines forming a zinc-finger structure and also the glutamic acid cluster are important for DNA repair function. ..

    ..Since TFIIH is a repair/transcription factor, TTD-specific alterations of TFIIH possibly result in transcriptional defects, which might be implication for the lack of increased incidence of skin cancers in TTD patients. ..

    ..Our in vitro studies showed that primary embryonic fibroblasts isolated from the xpg-deficient mice underwent premature senescence and exhibited the early onset of immortalization and accumulation of p53. ..
