Abstract:
DNA interstrand crosslinks (ICLs) can arise from reactions with endogenous chemicals, such as malondialdehyde - a lipid peroxidation product - or from exposure to various clinical anti-cancer drugs, most notably bifunctional alkylators and platinum compounds. Because they covalently link the two strands of DNA, ICLs completely block transcription and replication, and, as a result, are lethal to the cell. It is well established that proteins that function in nucleotide excision repair and homologous recombination are involved in ICL resolution. Recent work, coupled with a much earlier report, now suggest an emerging link between proteins of the base excision repair pathway and crosslink processing.

Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
