While the intensity of staining for FGF9 in CRC specimens was also significantly higher than that in matched normal tissues (Fig. 4A,B, P<0.001) and is closely associated with DJ-1 expression (R2=0.1529, P=0.0167) (Fig. S4C), demonstrating that FGF9 is overexpressed in human CRC. This evidence concerns the gene FGF9 and colorectal carcinoma.
