Analysis of breast cancer transcriptomes (METABRIC cohort) also evidenced a very good correlation between the expression of FOLR2 and those of genes of the “anti-inflammatory gene set”, which reached statistical significance in most cases (Figure 2C), and was highly significant for CD163 (Pearson: 0.72; p = 1.71 × 10−308) and even CD68 (Pearson: 0.59; p = 1.25 × 10−176), another widely used marker for macrophage identification (Figure 2C). The gene discussed is CD68; the disease is breast carcinoma.
