IL6 and ovarian cancer: GSEA analysis further demonstrated enrichment of the interferon gamma response (IFN-γ), OXPHOS, IL-6/JAK/STAT3 signaling pathway, chemical carcinogenesis-reactive oxygen species (ROS), chemokine signaling pathway, and cytokine-cytokine receptor interaction in the high-risk group, indicating their involvement in promoting ovarian cancer (Figure 6B and Supplementary Figure 2B).
