Cisplatin repair
WebHowever, the resistance of tumor cells against cisplatin would seriously influence the treatment efficacy for NSCLC. Up to now, nucleotide excision repair (NER) has been recognized as one of the important mechanisms for the cisplatin resistance, in which excision repair cross-complementation 1 (ERCC1) is known to be critically involved. WebMechanisms explaining cisplatin resistance include the reduction in cisplatin accumulation inside cancer cells because of barriers across the cell membrane, the faster repair of cisplatin adducts, the modulation of apoptotic pathways in various cells, the upregulation in transcription factors, the loss of p53 and other protein functions and a ...

WebAccording 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. When ATM inhibitors are made available in clinical practice in the future, acute renal injury must be closely monitored ( Uehara et al., 2024 ). WebWe show that the MutSα (MSH2-MSH6) heterocomplex is required to maintain cisplatin sensitivity, whereas the Mutsβ complex has no effect. These results can be correlated with the increased repair of cisplatin ICLs and ICL induced DNA double strand breaks (DSBs) in the resistant cells.
