In addition, KEGG target enrichment analysis [44] showed that among the ten potential pathways of quercetin and kaempferol in the treatment of spermatogenic disorders, in addition to cancer and vascular atherosclerotic diseases, the NF-κB inflammatory signaling pathway was the most relevant, which was also highly related to cytokine-mediated signaling pathway in the GO enrichment analysis (Figure 1D and Figure 2D). This evidence concerns the gene NFKB1 and cancer.
