MMP11 and cancer: In a study conducted by Boulay et al. [28], a new and unexpected role for MMP was revealed, that is, tumorigenesis induced by MMP-11 does not result from increased neo-angiogenesis or cancer cell proliferation, but from decreased cancer cell death through apoptosis and necrosis, indicating that the cellular function of MMP-11 is to favor cancer cell survival in the stromal environment.
