PARP1 and breast cancer: Interestingly, these results are supported by data provided by KMplot, an online tool [47], whereby basal-like BC patients with higher expression of PARP-1 have been indicated to have a longer disease-free interval (DFI; log-rank p = 0.022, HR = 0.67; Figure S5B) and OS (log-rank p = 0.015, HR = 0.59; Figure S5C).
