CXCL9 and melanoma: Although the chemokines CXCL9, CXCL10 and CXCL11 were reported to have an angiostatic effect when expressed by melanoma cells (Romagnani et al, 2001a, 2001b; Mehrad et al, 2007; Keeley et al, 2008), our study suggests that the chemokine CXCL9 may promote additional metastasis, when it is expressed in TuECs, by means of increasing transendothelial and melanoma migration.
