MMP9, MMP9: Click to Expand ⟱
Source: HalifaxProj(suppress)
Type:
Matrix metalloproteinase-9 (MMP-9) is an enzyme that plays a significant role in the degradation of extracellular matrix components.
MMP-9 facilitates the breakdown of the extracellular matrix, which can enable cancer cells to invade surrounding tissues and spread to distant sites (metastasis).
Elevated levels of MMP-9 have been associated with poor prognosis in several cancers, including breast, lung, and colorectal cancers.
MMP2 and MMP9: two enzymes are critical to tumor invasion.
