In the present study, the CXC chemokine family of cytokines (containing CXCL1, CXCL9, and CXCL10) was mostly enriched in human skin-related GO terms and KEGG pathways such as the chemokine signaling pathway and cytokine-cytokine receptor interaction, implying that the gene family might be important in regulating psoriasis. The gene discussed is CXCL10; the disease is psoriasis.
