LAMB2 and colorectal cancer: Studies by Suwen Ou et al. [23] found that MMP7 is associated with colorectal cancer metastasis and poor prognosis, while Roopali Roy et al. [24] discovered that MMP family members mediate cell proliferation, migration, invasion, differentiation, apoptosis, inflammation, and angiogenesis by degrading ECM proteins such as collagen type I and IV, laminin, fibronectin, fibrinogen, and proteoglycans, promoting both physiological and pathological processes.
