Decreased DNA Repair Efficiency by Loss or Disruption of p53 Function Preferentially Affects Removal of Cyclobutane Pyrimidine Dimers from Non-transcribed Strand and Slow Repair Sites in Transcribed Strand

Abstract excerpt

The tumor suppressor protein p53 plays a central role in modulating the cellular responses to DNA damage. Several recent studies, undertaken with the whole genomic DNA or full-length gene segments, have shown that p53 is involved in nucleotide excision repair and it selectively influences the adduct removal from the non-transcribed strand in the genome. In this study, we have analyzed the damage induction at...
