The significant KEGG pathways are chemokine signaling pathway (CCL5, CCL18, CCL19, CCL21, CXCL12, CXCL14, CXCL13), ​​NF-kappa B signaling pathway (CCL19, CCL21, CXCL12), intestinal immune network for IgA production (TNFRSF17, CXCL12), pathways in cancer (IGF1, CXCL12). Here, CXCL12 is linked to cancer.
