Similarly, A-kinase anchor protein 9 (AKAP9), replication protein A3 (RPA3) and SRC kinase associated phosphoprotein 2 (SKAP2) were enlisted into invasion assay since, although they had been linked to breast, lung, head and neck and pancreatic cancer [39], [40], [41], these genes have not been previously associated with tumor invasion. This evidence concerns the gene RPA3 and pancreatic neoplasm.
