Cell invasion (CD14, CTSB, CTSL, ETS1, FN1, FSCN, FST, INHBA, ITGB2, LOX, MMP2, MMP9, MMP11, MMP12, MMP13, MYLK, OSM, PLAU, RECK, RGS4, RUNX2, S100A4, SPP1, SULF1, TIMP3), adhesion of tumor cells (ADAM12, ANXA1, CCL3, CCL4, FN1, ICAM1, IL6, ITGA4, ITGB2, PLAU, SELE, THBS1), metastasis of carcinoma cell lines (CCL2, DAPK1, S100A4, TWIST1, WISP1), tumor cell spreading (FN1, PLAU, SNAI2, THBS1, TNC), progression of gastric carcinoma (APOE, COL1A1, COL1A2). This evidence concerns the gene SPP1 and carcinoma.
