β-Lapachone enhances Mre11-Rad50-Nbs1 complex expression in cisplatin-induced nephrotoxicity

Background Recent studies suggest a potential involvement of the Mre11-Rad50-Nbs1 (MRN) complex, a DNA double-strand breaks (DSBs) sensor, in the development of nephrotoxicity following cisplatin administration. β-Lapachone is a topoisomerase I inhibitor known to reduce cisplatin-induced nephrotoxicity. In this study, by assessing MRN complex expression, we explored whether β-lapachone was involved in DNA damage response in the context of cisplatin-induced nephrotoxicity.
