Cisplatin binding to dna
WebOct 15, 2010 · The mode of binding resembles the HMGB1 box A-cisplatin-DNA complex, which also lacks a primary intercalating residue. This study provides new insights into the binding mechanisms used by HMG boxes to recognize varied DNA structures and sequences as well as modulate DNA structure and DNA bending. Copyright © 2010 … WebSep 24, 2024 · Nucleotide excision repair is the first pathway that begins to repair DNA in the face of cisplatin resistance. This repair pathway is responsible for removing the bonds formed between platinum and DNA. Once CDDP binds to DNA, the cell can survive by activating DNA repair mechanisms or by tolerance to genetic damage.

WebOct 1, 1995 · The connection between cisplatin resist- ance and DNA repair has thus been established both by using cell lines and in tissue taken directly from patients. Whether or not differential DNA repair of individual types of DNA adducts is responsible for resistance has not yet been determined. WebThe three Pt drugs that prevail in the current treatment of cancer — cisplatin, carboplatin and oxaliplatin — all impair normal DNA functions by generating monoadducts as well as …
WebJun 3, 2013 · Cisplatin's selectivity in killing rapidly proliferating cancer cells is largely dependent on covalent binding to DNA via cisplatin's chloride sites that had been aquated. We hypothesized that cisplatin's toxicity in slowly proliferating or terminally differentiated cells is primarily due to drug-protein interactions, instead of drug-DNA binding. WebCisplatin, following activation by aquation, initiates cell death primarily through binding to DNA at the N7 of purine bases, leading to the formation of cross-links inhibiting DNA replication and transcription, triggering cell cycle arrest and apoptosis [ 3, 4 ].
