Next, the results showed that there were positive correlations between CCL5 and M1 macrophage infiltration assessed by XCELL and CIBERSORT (Rho = 0.487 and 0.62, respectively) but no positive correlation between CCL5 and M2 macrophage by CIBERSORT (Rho = -0.366), which indicated that a high expression of CCL5 might facilitate infiltration of M1 macrophage into BCa tumor tissue (Figures 5B, C). This evidence concerns the gene CCL5 and neoplasm.
