GZMB and breast carcinoma: 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.
