BRCA1 loss is linked to mitochondrial dysfunction, mtDNA instability, oxidative stress, and inflammatory remodeling, creating therapeutic vulnerabilities beyond homologous recombination deficiency.
- Why it matters: Incomplete responses to PARP inhibitors in HR-deficient settings suggest additional BRCA1-linked weaknesses are needed to improve precision oncology.
- What they did: The work synthesizes recent findings showing BRCA1 roles in mitochondrial quality control, metabolic and redox homeostasis, and innate immune signaling, framing a genome–mitochondria–immune axis.
- The result: Disrupting this axis amplifies genomic instability and inflammatory signaling, supporting combination strategies that pair PARP inhibition with mitochondrial, metabolic, epigenetic, and immune-targeted therapies.
