In addition, the interleukin (IL)-17 signaling pathway plays a tumorigenic role in CRC and is associated with the activation of nuclear factor κ-light-chain-enhancer of activated B (NF-κB) cells and mitogen-activated protein kinases (MAPKs), which upregulate the survival pathways required for the growth and development of tumor cells (Wang et al., 2014). This evidence concerns the gene IL17A and colorectal carcinoma.
