To further corroborate a link of CCL20 exposure to HGF secretion in colorectal cancer, a correlative analysis was performed between gene expression of CCL20 and HGF as well as between CCL20’s receptor, CCR6, and HGF and using data from human colorectal cancers collected by the Cancer Genome Atlas (TCGA) (Figure 1D). This evidence concerns the gene HGF and colorectal cancer.
