MMP14 and glioblastoma: In U87 glioblastoma cells, Djerir et al. [56] found that ConA-mediated MT1-MMP induction was inhibited by EGCG and catechin gallate, and endoplasmic reticulum stress biomarker GRP78 induction was inhibited by EGCG, catechin gallate, and gallocatechin gallate, whereas proMMP2 activation was inhibited by EGCG and gallocatechin gallate.
