To determine whether the association between the two genes comprising our response biomarker and immune infiltration in TCGA bulk tissues was driven by higher expression of these genes in immune cells rather than cancer cells, we examined the expression patterns of CCL22 and TNFSF10 using publicly available scRNA-seq datasets of breast (26) and prostate (27) cancers from the Broad Institute Single Cell portal. Here, TNFSF10 is linked to cancer.
