Finally, we revealed the correlation between the expression levels of ANXA1 and immunoinhibitors in sarcoma patients by a heatmap of correlation (Figure 9C), and the results suggested that the expression levels of ANXA1 were associated with 20 immunoinhibitors, among which HAVCR2, CSF1R, IL-10, LGALS9, IL10RB, PDCD1LG2, TGFB1, TGFBR1, TIGIT and CD96 showed strong positive correlations (Figure 9D and Supplementary Figure 3). Here, PDCD1LG2 is linked to sarcoma.
