It is well established that Ras oncogenes facilitate neoplastic conversion by stimulating tumor cell growth, survival and motility. However, current studies have indicated that the role of Ras in malignant transformation extends beyond these cell-intrinsic effects to include the establishment of a pro-tumorigenic host environment. We have recently demonstrated that Ras-induced secretion of the chemokine Interleukin-8 (CXCL-8/IL-8) elicits a local inflammatory reaction that is critical for neo-vascularization and sustained tumor growth. Our data identify a novel mechanism by which the Ras oncogene promotes tumor-host interactions that are essential for cancer progression, and suggest that CXCL-8 could serve as a surrogate marker for in-vivo Ras activity.
