Figures 5A–D showed the number of cells in each cell type, with the distribution and number of various TME-related cells presented. In this data set, CD4+ T Cells were the most abundant immune cells (n = 5,413), whereas NR1H3 was highly expressed in monocyte/macrophage (Figure 6D). GEPIA2021 platform also revealed the consistent results that NR1H3 is highly expressed in macrophages in BRCA tumor/BRCA normal from TCGA and breast tissue from GTEx using EPIC algorithm (Figure 6E). The gene discussed is CD4; the disease is invasive breast carcinoma.
