Epistatic role of base excision repair and mismatch repair pathways in mediating cisplatin cytotoxicity. 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 ).

WebAuger electrons can induce nanoscale physiochemical damage to DNA. The present study reports a sequential and systematic evaluation of the relationship between DNA damage such as double-strand breaks (DSBs) and the cell cycle for the Auger electron-emitting agent radiolabeled cisplatin with DNA binding ability. For dynamic imaging analysis, we … 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 …

The alarm signal is sent 'Attention, repair, do not divide further.' WebApr 14, 2024 · For platinum derivatives, the situation is more complex as the repair of the cytotoxic lesions induced by cisplatin is not enhanced by PARP inhibitors in HR-proficient cells . Furthermore, the platinum-induced DNA crosslinks are repaired by transcription-coupled nucleotide excision repair (TC-NER) and translesion synthesis independently of …
