CXCL14 and colorectal cancer: The chemokine CXCL14 is downregulated in gastric cancer cells when compared to healthy tissue, due at least in part to aberrant hypermethylation in exon 1 of the gene (Hu et al., 2013), and in colorectal cancer, where hypermethylation and loss of CXCL14 expression are linked to proliferation, migration, invasion, and EMT through NF-κB (Cao et al., 2013).
