Expression of the other immune markers such as FOXP3, ADGRE1 (the gene encoding F4/80), PDCD1 (PD-1 gene), CD274 (PD-L1 gene) alone or in combination with ING4 did not correlate with patient survival (Fig 6C), highlighting the unique relationship between GZMB and ING4 expression in the basal subtype of breast cancer. Here, ADGRE1 is linked to breast carcinoma.
