    Efficacy of PARP inhibitors in patients with advanced high grade serous ovarian cancer according to BRCA domain mutations. (ESMO-GC 2023)
    Although limited by a small cohort size our analysis suggests that DNA-BD BRCA2mut may predict increased sensitivity to PARPi. Legal entity responsible for the study Department of Clinical Medicine and Surgery, University of Naples Federico II, Naples, Italy.

    large genome rearrangement of BRCA1/2 in BRCA mutation negative ovarian cancer patients (AACR-NCI-EORTC 2022)
    The detection of more BRCA1/2 mutations in patients of ovarian cancer is important for efforts to provide targeted therapy. No

    Mitotic DNA synthesis is caused by transcription-replication conflicts in BRCA2-deficient cells. (PubMed, Mol Cell)
    Importantly, the MiDAS sites identified in BRCA2-deficient cells also represent hotspots for genomic rearrangements in BRCA2-mutated breast tumors. Thus, our work provides a mechanism for how tumor-predisposing BRCA2 inactivation links transcription-induced DNA damage with mitotic DNA repair to fuel the genomic instability characteristic of cancer cells.
