Interferon (IFN) Cell Signaling Pathway. Adapted from Raza et al. To determine whether impaired IFN signaling is a function of cancer stage, IFN-α- and IFN-γ-stimulated pSTAT1 was compared between stage II, III, and IV breast cancer subgroups. While numerous anti-tumor activities have been described for IFNs, IFNs have also been associated with tumor growth and progression. Understanding Cancer. 11. pp. Interestingly, activation of STING promotes its binding to USP35 in a STING phosphorylation-dependent manner. As AGO1x expression is tightly linked to breast cancer cell proliferation, our study suggests a new direction for limiting tumor growth. Stimulator of interferon genes (STING) is an adaptor protein that plays an important role in the activation of type I interferons in response to cytosolic nucleic acid ligands. Amplification of the immune response is a result of an increase in antigen presentation machinery, positive feedback resulting in increased interferon-γ pathway signaling, production of chemokines that attract other immune cells favorably altering the tumor microenvironment and inhibition of immune exclusion cancer signatures.
