Further, a significant correlation was found between the expression of FOLR2 and CD163 using the TCGA cohorts for breast carcinoma, melanoma and HNSC (Figure 2D and not shown), whereas no correlation was seen between FOLR2 and the epithelial-specific EPCAM gene in any of the analyzed tumors (data not shown). The gene discussed is EPCAM; the disease is breast carcinoma.
