CXCR3 and colonic neoplasm: Among the other chemokine receptors under study in this context, CXCR3 has been identified in various cancer cells (Jones et al, 2000; Goldberg-Bittman et al, 2004; Ben-Baruch, 2006; Engl et al, 2006; Albini and Sporn, 2007) and was recently reported to play an important role in breast cancer metastasis to the lung (Müller et al, 2001; Kawada et al, 2004) as well as in melanoma and colon cancer metastasis to the lymph nodes (Walser et al, 2006; Kawada et al, 2007).
