Notably, pathways like the T cell receptor signaling pathway, chemokine signaling pathway, IL-17 signaling pathway, TNF signaling pathway, and Toll-like receptor signaling pathway were also notably enriched, suggesting that Cpn may ameliorate obesity through multiple pathways, related to both metabolic regulation and inflammatory immunomodulation. The gene discussed is CPN1; the disease is obesity due to melanocortin 4 receptor deficiency.
