Relationships between the PARP7 signature and known inflammatory signatures were recapitulated in the TCGA basal-like TNBC cohort (Fig. S9b-d), as well as in HR + breast cancer in the METABRIC cohort (Fig. S9e), albeit without the difference in survival in the TCGA cohort likely due to its known limitations for survival analysis56. This evidence concerns the gene TIPARP and breast cancer.
