CCL2 and neoplasm: This study exhibited that in LUAD, the WDR6 expression negatively correlated with the tumor‐associated macrophages (TAM) markers, including CCL2, CD68, and IL10, and monocyte markers, such as CD86 and FCGR3A (CD16); however, there was no statistically significant correlation between the expression of WDR6 and M1 or M2 macrophages markers, such as NOS2 and CD163 (Figure 3A−D).
