Genes related to multiple cell lineage–progenitor potency (DTR, SOX1, FGFR2, NOTCH1, FOLH1, NEUROG2, FLT3LG, TEKT3, CDH5, FLT4, TEK) and tumor immune response (DPP4/CD26) were upregulated in 9 CRC samples and 20 breast cancer samples, but other endothelial genes (FGF4, SOX2, NRG1, FLT1, CDC2, MCAM, EGFR, FGFR1, BMP1, PECAM1, FGF6, FGF5, VWF) were not (Figure 5). This evidence concerns the gene PECAM1 and breast carcinoma.
