HLA-DRA and invasive breast carcinoma: After adjusting for tumour purity, we found that CELF2 expression was still related to most of these marker sets, such as T‐cell markers (CD3E and CD2), monocyte markers (CD86 and CSF1R), TAM markers (CD68 and IL10), M2 macrophages markers (CD163 and MS4A4A) and DC markers (HLA‐DRA, HLA‐DPA1, NRP1 and ITGAX) in BRCA and LUSC (p < 0.0001 and r > 0.6; Figure 4A–J).
