Analyses of the Molecular Taxonomy of Breast Cancer International Consortium (METABRIC) and TCGA-BRCA datasets showed a positive correlation between HNRNPA2B1 and NQO1 expression (Extended Data Fig. 3b,c), and, in the case of the TCGA-BRCA dataset, between HNRNPA2B1 expression and NQO1 stability (Extended Data Fig. 3c). Here, NQO1 is linked to breast cancer.
