It further supports that IL-19 not only directly facilitates cell proliferation, cell migration, and metastasis but it also prompts the expression of IL-1β, IL-6, TGF-β, MMP-2, MMP9, CXCR4, and fibronectin, which supply of a microenvironment for tumor growth and metastasis [13]. This evidence concerns the gene FN1 and neoplasm.
