The results showed that PSMC5 was positively correlated with CCL3, CCL4, and CCL5 (Figure 6E), which were proved to be positive regulators of tumor-associated macrophage (TAM; Eissmann et al., 2019) and tumor-infiltrating neutrophil (TIN) abundance (Mukaida et al., 2020). Here, CCL4 is linked to neoplasm.
