Enrichment plots of Grade 3 BCs showing association with cell proliferation/ cell cycle related gene sets by GSEA compared to Grade 1+2 BCs in the all cohorts. Grade 3 tumors were associated with E2F targets, G2M checkpoint, mTORc1 signaling and MYC targets v1 and v2 (all p<0.001) in the all cohorts. Additional enrichment plots of Grade 3 BCs showing association with immune activity related gene sets by GSEA compared to Grade 1+2 BCs in the METABRIC cohort. Grade 3 tumors were associated with Allograft rejection, INF gamma response, INF alpha response and Inflammatory response (all p<0.001). Similar trends were observed in the TCGA and GSE25066 cohorts.
