Research Article: A Progressively Disassembled DNA Repair Inhibitors Nanosystem for the Treatment of BRCA Wild-Type Triple-Negative Breast Cancer

Date Published: 2023-10-24

Abstract:
Breast cancer is the leading cause of morbidity and mortality in women worldwide, accounting for % of new cancer cases and % of deaths., Triple-negative breast cancer (TNBC) is a highly heterogeneous breast cancer type characterized by a lack of hormone receptors and a poor clinical prognosis., Although chemotherapy is still the first-line treatment for most patients with TNBC, adverse side effects limit its application., In addition, about –% of TNBC patients have mutations in BRCA genes, which also seem to be one of the driving factors of TNBC., Meanwhile, BRCA-regulated DNA homologous recombination (HR) repair is often absent or lost in cancer types with BRCA mutations, which are sensitive to some DNA repair inhibitors.–
