Also, the correlation between the mRNA expression of CDC20 and infiltrating immune cells in BC showed a significant positive association with a plethora of B cells (cor = 0.198, p = 3.95 × 10−10), CD4+ T cells (cor = 0.075, p = 1.98 × 10−02), neutrophils (cor = 0.125, p = 1.2 × 10−04), and dendritic cells (cor = 0.161, p = 6.17 × 10−07). Here, CD4 is linked to breast cancer.
