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- WebAnticancer activity of cisplatin (cis-diamminedichloroplatinum) is believed to result from its interaction with DNA. The drug reacts with nucleophilic sites in DNA forming …
WebCisplatin-induced DNA lesions and repair mechanisms. A) The nucleotide excision repair (NER) pathway is responsible for removing cisplatin-induced DNA adducts (such as 1,2 and 1,3 intrastrand adducts), while … WebCisplatin is a major anticancer drug that kills cancer cells by damaging their DNA. Cancer cells cope with the drug by removal of the damages with nucleotide excision repair. 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. WebThis indicates the rate of cisplatin binding in gDNA and mtDNA is similar; however, the mtDNA is without the NER DNA repair system. In contrast, in vivo studies where adult …

WebThe mechanism for the processing and removal of ICLs by DNA repair proteins involves nucleotide excision repair (NER), homologous recombination (HR) and fanconi anemia (FA) pathways. In this report, we monitored the processing of a flanking uracil adjacent to a cisplatin ICL by the proteins involved in the base excision repair (BER) pathway. grant of probate v letters of administrationWebAccording 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.
