Of these, the average expression of the two genes, including CD70 and PDCD1, and the 12 isoforms derived from the seven genes, including CD40, CD70, IL6, IL10, STAT1, STAT6, and TNFRSF14, were cancer immunotherapy-related genes (false discovery rate (FDR) < 0.01) (Table 2). This evidence concerns the gene IL6 and cancer.
