Proteomic analysis uncovers common effects of IFN-γ and IL-27 on antigen presentation machinery components in human cancer cells


ABSTRACT: IL-27, a member of the IL-12- family of cytokines, has shown anti-tumor activity in several pre-clinical models due to anti-proliferative, anti-angiogenic and immune-enhancing effects. On the other hand, IL-27 demonstrated immune-regulatory activities and inhibition of auto-immunity in mouse models. Also, we reported that IL-27, similar to IFN-, induces the expression of IL-18BP, IDO and PD-L1 immune-regulatory molecules in human cancer cells. Here, a proteomic analysis reveals that IL-27 and IFN- display a broad overlap of functions on human ovarian cancer cells. Indeed, among 990 proteins modulated by either cytokine treatment in SKOV3 cells, 814 showed a concordant modulation by both cytokines, while a smaller number (176) were differentially modulated. The most up-regulated proteins were common to both IFN-γ and IL-27. In addition, functional analysis of IL-27- regulated protein networks highlighted pathways of interferon signaling and regulation, antigen presentation, protection from natural killer cell-mediated cytotoxicity, regulation of protein polyubiquitination and proteasome, aminoacid catabolism and regulation of viral protein levels.
