Cisplatin binding to dna

WebWe have seen how cisplatin binds DNA, and now we want to understand how the binding of cisplatin to DNA leads to programmed cell death. Researchers have found that this … WebIt does not promote cross-linking which is the cause of the gene replication process. The cisplatin molecule binds with a protein on one side and the DNA molecule on the other. The protein is critical; it protects the cisplatin molecule from being removed by DNA repair mechanisms in the cell.

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 was found to bind to bovine erythrocyte-SOD at His19 with high selectivity as no other binding sites were identified. 83 Surprisingly, amine ligands as opposed to the chlorido ligand underwent ligand exchange reactions with His19 of SOD.

WebCisplatin covalently binds to nuclear DNA (nDNA) inducing DNA damage and apoptosis. Cisplatin-induced DNA damage up-regulates p53 and induces cell cycle changes in DRG neurons. Cell cycle changes include up-regulation of cyclin D1, activation of CDK4/6 complexes and phosphorylation of Rb. WebTransplatin, (an isomer of cisplatin that has the chlorine atoms opposite each other, rather than on the same side) also forms adducts with DNA, but mostly mono-adducts. It does …
