Base lesions, which are structurally simple and predominantly fixed by base excision repair (BER), can trigger the ataxia telangiectasia mutated (ATM)-checkpoint kinase 2 (Chk2) pathway, a DDR component. How these lesions trigger DDR remains unclear. Here we show that, for alkylation damage, methylpurine-DNA glycosylase (MPG) and apurinic/apyrimidinic endonuclease 1, both of which function early in BER, are required for ATM-Chk2-dependent DDR. In addition, other DNA glycosylases, including uracil-DNA glycosylase and 8-oxoguanine glycosylase, which are involved in repairing deaminated bases and oxidative damage, also induced DDR. The early steps of BER therefore play a vital role in modulating the ATM-Chk2 DDR in response to base lesions, facilitating downstream BER processing for repair, in which the formation of a single-strand break was shown to play a critical role. Moreover, MPG knockdown rescued cell lethality, its overexpression led to cell death triggered by DNA damage and, more interestingly, higher MPG expression in breast and ovarian cancers corresponded with a greater probability of relapse-free survival after chemotherapy, underscoring the importance of glycosylase-dependent DDR. This study highlights the crosstalk between BER and DDR that contributes to maintaining genomic integrity and may have clinical applications in cancer therapy."xsd:string |
