Research Abstract |
We studied how mutations in the XPD gene result in different skin cancer susceptibilities in patients with xeroderma pigmentosum (XP) or trichothiodystrophy (TTD). XP-D and TTD cells were both deficient in the repair of UV-induced DNA damage because of helicase activity defects of TFIIH. Since TFIIH also acts as a coactivator, TTD-specific decrease in TFIIH content possibly results in transcriptional defects, which might be implication for the lack of increased incidence of skin cancers in TTD patients.
