Although most cancer tissues showed an increase of furin (Figure 4A), the furin expressions were significantly upregulated only in 2 types of cancers, esophageal carcinoma (ESCA) and testicular germ cell tumors (TGCT) (Figure 4A in red, 4B of left two panels, p<0.01). This evidence concerns the gene FURIN and carcinoma of esophagus.
