Interferon signaling restrains renal cell carcinoma heterogeneity

Abstract

Type I interferon (IFN) is central to cancer surveillance as it mediates both direct and immune-mediated oncosuppressive effects. A recent study by Perelli et al. suggests that the ability of renal cancer cells to tolerate complex karyotypic alterations elicited by chromosomal instability (CIN), and ultimately acquire full metastatic potential, is also negatively regulated by IFN signaling.
