Results showed that FIGN expression was positively correlated with B cell (R=0.223, P=3.10e-05), CD8+ T cell (R=0.203, P=1.52e-04), CD4+ T cell (R=0.324, P=7.93e-10), macrophage (R=0.381, P=3.28e-13), neutrophil (R=0.427, P=1.02-16), and dendritic cell (R=0.311, P=4.89e-09), while negatively correlated with tumor purity (R=-0.062, P=2.48e-01) (Figure 4A). The gene discussed is CD8A; the disease is neoplasm.
