U2OS cells strongly overexpressed MMP9 (152-fold increase), confirming the high metastatic potential of this cell line coupled with high expression levels of genes involved in cell cycle regulation (i.e., BRCA1, CCNE1, CDC25A, CHEK2, E2F1), apoptosis (i.e., BCL2, BCL2L1), membrane integrity and tumor invasion (i.e., COL18A1, ITGA3, MMP9, MCAM), cell proliferation (i.e.,. Here, BCL2 is linked to neoplasm.
