IL-6, IL-8, monocyte chemoattractant protein-1 (MCP-1), and tissue inhibitor of metalloproteinase-1 (TIMP-1) promote tumor cell growth by activating FAs synthesis, possibly through the involvement of the PI3K/AKT pathway and peroxisome proliferator-activated receptor (PPAR) signaling. This evidence concerns the gene CCL2 and neoplasm.
