For example, the CXC chemokine 7 (CXCL7) inhibits growth and migration of oral tongue squamous cell carcinoma cells via the EMT signaling pathway [11], CC-Chemokine Ligand 18 (CCL18) induces EMT in lung cancer and elevates the invasive potential [12], and CXC chemokine 9 (CXCL9) regulates TGF-β1-induced EMT in human alveolar epithelial cells [13]. The gene discussed is CCL18; the disease is lung cancer.
