Figure 7A shows the correlation between IL-17B expression level in pan-cancer and immunostimulators. The strongest correlations of ENTPD1 (r = 0.54, p < 0.001), CXCL12 (r = 0.43, p < 0.001), CD27 (r = 0.27, p < 0.001), and IL-17B were in BLCA (Figures 7D–F). Figure 7B shows the correlation between IL-17B expression level and immunoinhibitors. In some tumors, such as CHOL, ESCA, and COAD, there were mainly positive correlations. In other tumors, such as DLBC and SRAC, there were mainly negative correlations. Figure 7C shows the correlation between IL-17B expression level and MHC molecules. The gene discussed is CXCL12; the disease is cancer.
