The most influenced pathways include “immune system”, “signaling by platelet-derived growth factor (PDGF)”, “adaptive immune system”, “axon guidance”, “pathways in cancer”, “transmembrane transport of small molecules”, “mitogen-activated protein kinases (MAPK) pathway”, “developmental biology”, “signaling by nerve growth factor (NGF)”, and “SLC-mediated transmembrane transport” (Fig 1). Here, CCL21 is linked to cancer.
