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. WebApr 6, 2024 · The DNA damage response and repair (DDR) gene set, consisting of 276 ... NAC and prolonged survival. 34-36 It is hypothesized that these mutations may increase the sensitivity of tumor cells to cisplatin-induced DNA damage, thereby enhancing the drug's efficacy in these tumors. 37 The incidence of DDR gene mutations was more frequent in …

WebRole of Mismatch Repair Proteins in the Processing of Cisplatin Interstrand Cross-Links. DNA Repair. 2015;35:126-36. Anbarasi Kothandapani, Akshada Sawant, Venkata Srinivas Mohan Nimai Dangeti, Robert W. Sobol, and Steve M. Patrick. Epistatic role of base excision repair and mismatch repair pathways in mediating cisplatin cytotoxicity. 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. 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. dick\u0027s bathing suits
