Herein we show that MMP-2 is up-regulated in resected colorectal tumors and degrades β1 integrins with the release of fragments containing the β1 I-domain.
Matrix metalloproteinase (MMP)-7 (matrilysin-1) plays significant roles in the growth, invasion, and metastasis of colorectal tumors, while (-)-epigallocatechin-3-gallate (EGCG), a green tea polyphenol with chemopreventive properties, has been shown to be an inhibitor of MMP-2 and MMP-9.
We evaluated levels and activity of gelatinase A (MMP-2) and gelatinase B (MMP-9), as well as stromelysin-1 (MMP-3) expression in 101 sporadic colorectal tumors in consideration of the microsatellite instability (MSI) status of the groups.
