WebAuger electrons can induce nanoscale physiochemical damage to DNA. The present study reports a sequential and systematic evaluation of the relationship between DNA damage such as double-strand breaks (DSBs) and the cell cycle for the Auger electron-emitting agent radiolabeled cisplatin with DNA binding ability. For dynamic imaging analysis, we … WebJan 18, 2024 · Two major nucleotide excision repair pathways, transcription-coupled repair (TCR) and global repair (GR), are well known to remove cisplatin-induced DNA …
WebCisplatin is among the most widely used broadly active cytotoxic anticancer drugs; however, its clinical efficacy is often limited by primary or the development of secondary resistance. Several mechanisms have been implicated in cisplatin resistance, including reduced drug uptake, increased cellular thiol/folate levels and increased DNA repair.
WebDNA repair DNA repair is a mechanism contributing to the cisplatin resistance of many tumor types, such as ovarian, testicu-lar, head and neck, and non-small cell lung carcinomas (NSCLCs) (Bowden 2014), and numerous studies show that nucleotide excision repair (NER) is an important DNA repair mechanism participating in DNA repair of can- WebCisplatin, a tiny molecule with platinum bound to two amines and two chlorides, is exactly this type of game changer: in the mid-1970s, is was found to be highly effective in treating testicular cancers. Cisplatin …
WebAccording to M. Uehara et al., ATM inhibition worsens tubular injury via upregulating p53-dependent pro-apoptotic signaling and does not enhance DNA repair following cisplatin-induced DNA damage. When ATM inhibitors are made available in clinical practice in the future, acute renal injury must be closely monitored ( Uehara et al., 2024 ).
