IL6 and melanoma: Our melanoma invasion-specific signature is notably characterized by the inclusion of several genes involved in chemotaxis and the inflammatory response (CXCL1, CXCL2, IL8, and IL6), cell adhesion (HNT, ITGA4, ITGB8, CSPG2, ZP4, and FLRT3), and extracellular matrix organization (MMP1, COL4A1, COL4A2, and COL5A2) (Table 3).
