To build and expand on our previous analysis of IBC tumor cells surviving under chronic stress stimuli, which identified genes in the anti-apoptotic signaling, oxidative stress response, immune, and TGFβ-related genes, we calculated the gene signature scores for the above pathways in the TCGA breast cancer subtypes and by patient race, AA and W (Fig. 1d). Here, TGFB1 is linked to inflammatory breast carcinoma.
