Based on the identified literature (9–22), IFI30, GBP1, and GBP4 suppress mouse primary T cell activation in vitro and mouse innate immune response in vivo while IFI30 and GBP1 appear to increase cell proliferation in a glioma cell line and two breast cancer cell lines but diminish cell proliferation in a colon cancer cell line. Here, IFI30 is linked to breast cancer.
