IRF4 and ovarian cancer: The expression of SUCNR1 also showed significant correlation with the expressions of interleukin receptors (such as IL2RA, IL9R, and IL15RA, p < 0.0001), interferon receptors (such as IFNAR1, IFNAR2, IFNGR1, and IFNGR2, p < 0.0001), and even interferon regulatory factors (such as IRF1, IRF2, IRF4, and IRF5, p < 0.0001), in ovarian cancer (Figures 4A,C–E).
