Consistent with in vitro results (Appendix Fig S7C and D), neither pyridostatin nor its combination with NU‐7441 and/or paclitaxel suppressed growth of BRCA2+/+ tumours (Appendix Fig S8A–C, Appendix Table S4) or had an impact on mouse survival (Appendix Fig S8D, Appendix Table S5). This evidence concerns the gene BRCA2 and neoplasm.
