KEGG analysis showed that compared to C2, C1 displayed the activation of tumor suppressor pathways like estrogen signaling pathway, ferroptosis, IL-17 signaling pathway, and amino acid metabolic pathway, with the suppression of cancer-associated signaling pathways such as gastric cancer, basal cell carcinoma, Wnt signaling pathway, and neurotransmission. The gene discussed is IL17A; the disease is neoplasm.
