We analyzed the correlations in TIMER between KIF23 and marker genes of different immune cells, including CD8+ T cells, T cells(general), B cells, monocytes, TAMs, M1 macrophages, M2 macrophages, neutrophils, NK cells, and DCs in GC, using esophageal carcinoma (ESCA) as the control. This evidence concerns the gene CD8A and carcinoma of esophagus.
