  • Original language description

    NQO1 guards against oxidative stress and carcinogenesis and stabilizes p53. We find that a homozygous common missense variant (NQO1*2, rs1800566(T), NM_000903.2:c.558C4T) that disables NQO1 strongly predicts poor survival among two independent series ofwomen with breast cancer (P 1/4 0.002, N 1/4 1,005; P 1/4 0.005, N 1/4 1,162), an effect particularly evident after anthracycline-based adjuvant chemotherapy with epirubicin (P 1/4 7.52 106) and in p53-aberrant tumors (P 1/4 6.15 105). Survival after metastasis was reduced among NQO1*2 homozygotes, further implicating NQO1 deficiency in cancer progression and treatment resistance. Consistently, response to epirubicin was impaired in NQO1*2-homozygous breast carcinoma cells in vitro, reflecting both p53-linked and p53 independent roles of NQO1. We propose a model of defective anthracycline response in NQO1-deficient breast tumors, along with increased genomic instability promoted by elevated reactive oxygen species (ROS), and suggest
