MMP2 and neoplasm: Increasing MMP10 expression stimulates the expression of HIF-1α and MMP2 (pro-angiogenic factors) and PAI-1 and CXCR2 (pro-metastatic factors), and accordingly, targeting MMP10 with siRNA in vivo resulted in diminution of xenograft tumor growth with a concomitant reduction of angiogenesis and a stimulation of apoptosis [48].
