WebROS can induce single or double-strand breakage, nucleotide alterations, deoxyribose changes, and DNA cross-linking in DNA. If oxidative DNA damage is not repaired before DNA replication, it could lead to cell death, DNA mutation, replication mistakes, and genomic instability (Cooke et al., 2003; Schupp et al., 2016). WebThe DNA binding is similar to cisplatin, and the complex forms a highly stereoselective adduct on DNA, but not for reactions with mono- and dinucleotides. 98 In cell lines with previously determined mechanisms of cell resistance, AMD473 showed little cross-resistance compared with cisplatin or carboplatin. cf栽赃挂购买
