There were significantly higher frequencies of FasL+ NK cells in the tumour (n = 9) of OAC patients, compared to the circulation (n = 17) and omentum (n = 14); circulation vs. tumour (4.014% vs. 41.15%, p < 0.0001), omentum vs. tumour (11.44% vs. 41.15%, p = 0.0007) (Figure 6A). The gene discussed is FASLG; the disease is neoplasm.
