CFH and cancer: The KEGG pathway enrichment unveiled that the DEGs primarily participated in micro RNAs in cancer, pathways in cancer FoxO signaling, the C-type lectin receptor signaling pathway, the cytokine–cytokine receptor signaling pathway, the HF-1 signaling pathway, the IL-17 signaling pathway, the NF-κB signaling pathway, and the TNF signaling pathway (Figure 5).
