Besides, exploring the correlation between GPX7 and sets of immunological markers using the TIMER2.0 database, we also observed significant correlations between GPX7 and the monocyte marker CD115, the M1 macrophage marker IRF5, the neutrophil marker CD11b, the NK marker KIR2DL3, CD4+ marker CD11c, the Th2 marker STAT6, the Tfh marker BCL6, the Th17 marker STAT3 and Treg markers FOXP3, STAT5B, TGFβ (Supplementary Table S8), therefore suggesting that GPX7 expression differently affect tumor immune-stroma in these types of cancer. This evidence concerns the gene STAT3 and cancer.
