The IFNγ ssGSEA scores were significantly negatively correlated with PA combined, synthesis, and hypusine ssGSEA scores in seven (r range: −0.42 to −0.17), six (r range: −0.45 to −0.25), and 12 (r range: −0.38 to −0.15) cancer types, respectively (FDR q < 0.25). This evidence concerns the gene IFNG and cancer.
