WebThis antibody enables the quantification of cisplatin-induced adducts on DNA. It has also been recently used for isolation of DNA fragments carrying adducts to enhance the sensitivity of subsequent PCR-based analyses and is central to ongoing studies of variation in the nature of cisplatin adducts formed in different cell lines. WebMar 9, 2024 · The strategy of tuning both apoptosis and DNA repair pathways opens a promising window to overcoming resistance to cisplatin in anticancer chemotherapy, and is also a breakthrough in the design of multitalented platinum-based anticancer drugs.
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 … WebAug 1, 2024 · Cisplatin treatment mainly induces intra- and interstrand DNA cross-links. These lesions are repaired by NER. Low expression of NER related proteins (e.g. ERCC1, XPF and XPA) are a rate limiting factor for cisplatin-DNA cross-link repair. High expression of HMGB1/4 can inhibit NER.
WebLTTs recovered rapidly from cisplatin stress compared to parental cells. In LTTs, to various extents, cisplatin exporters and metallothioneins were induced, cisplatin adduct levels and DNA damage were decreased, whereas expression of DNA repair factors and specific anti-apoptotic factors was elevated. WebSep 1, 2002 · NER 3 is the main mechanism for removing cisplatin adducts. NER has been elucidated at the molecular level in recent years, and it is now possible to follow step by step the repair of adducts and cross-links on adjacent DNA bases .The NER molecular machinery includes well-defined proteins that are mutated in XP and CS patients .NER …
