The human BTF2 (TFIIH) transcription factor is a multisubunit protein involved in transcription initiation by RNA polymerase II (B) as well as in DNA repair. In addition to the previously characterized p62 and p89/ERCC3 subunits, we have cloned two other subunits of BTF2, p44 and p34. The gene encoding p44 appeared to be the human counterpart of SSL1, a(More)
XPB is a subunit of the basal transcription factor TFIIH, which is also involved in nucleotide excision repair (NER) and potentially in cell cycle regulation. A frameshift mutation in the 3'-end of the XPB gene is responsible for a concurrence of two disorders: xeroderma pigmentosum (XP) and Cockayne's syndrome (CS). We have isolated TFIIH from cells(More)
OBJECTIVE Management of post-operative pain is important for decreasing post-operative morbidity and mortality. After evaluating our pain score database of patients undergoing cardiac surgery (2007-2009) we revised our pain protocol. The new protocol allows nurses to administer analgesic medication without consulting the attending physician. The setting was(More)
The phenotypic consequences of a nucleotide excision repair (NER) defect in man are apparent from three distinct inborn diseases characterized by hypersensitivity of the skin to ultraviolet light and a remarkable clinical and genetic heterogeneity. These are the prototype repair syndrome, xeroderma pigmentosum (XP) (seven genetic complementation groups,(More)
Rodent ultraviolet light (UV)-sensitive mutant cells in complementation groups (CGs) 1 and 4 normally are known for their extraordinary (approximately 80-100 x) sensitivity to mitomycin C (MMC), although some CG1 mutants with reduced MMC sensitivity were previously reported (Stefanini et al. (1987) Cytotechnology 1, 91). We report here new CG1 and CG4(More)
