Sample text

42 The addition and recruitment of NER factors led to the increased release of RNA polymerase IIO from the DNA template. 44 Following release of torsional stress, Top1 reseals the nick and restores the integrity of the double helix religation. However, CPT is known to block the religation reaction of Top1, resulting in accumulation of Top1-cc. In addition, collision of Top1-cc with replication forks results in abortive Top1-associated DNA double stranded breaks, while collision of Top1-cc with the transcriptional machinery converts Top1-cc into abortive Top1-associated DNA single stranded breaks, which can block transcription.

It is suggested that CS is a disorder with DNA repair/transcription-deficiencies. 1 NER is well conserved from Escherichia coli to mammals and consists of the consecutive steps of damage recognition, dual incisions on either side of the damage, excision of 24-32 oligonucleotides containing the damage, gap filling by repair DNA synthesis using the error-free strand as a template and ligation (Fig. 1). 2 XP patients are hypersensitive to sunlight and show an increased incidence of skin cancers in sunlight-exposed areas.
