Several studies have shown that BRCA1 expression is altered, albeit rarely, in glioblastoma, leading to poor prognosis and increased tumor aggressiveness. In addition, the communication of BRCA1 with other molecular pathways such as p53 and PTEN further complicates its role in glioblastoma pathogenesis. Targeting BRCA1-related pathways in these cases has shown the potential to improve the efficacy of standard treatments, including radiotherapy and chemotherapy. The development of (Poly (ADP-ribose) Polymerase) PARP inhibitors that exploit the lack of HR also offers a therapeutic approach to glioblastoma patients with BRCA1 mutations.
