The distribution of STAT1, STAT2, STAT3, STAT4, STAT5A, STAT5B, and STAT6 expression in myeloid cells in pan-cancer single-cell transcriptional atlases of tumor infiltrating myeloid cells and tumor infiltrating T cells was demonstrated in Figure 6A, Supplementary Figures S11A–G, which revealed that STAT1 and STAT3 were generally high-expressed in myeloid cells, while STAT4 and STAT5B had basically no expression. The gene discussed is STAT4; the disease is cancer.
