Collagenase expression and activity is modulated by the interaction of collagen types, hypoxia, and nutrition in human lung cells

Hypoxia not only controls organogenesis, embryogenesis, and wound repair, but also triggers tumor progression and metastasis. Matrix metalloproteinases (MMP), especially gelatinases (MMP‐2, MMP‐9) regulate the composition and stability of the extracellular matrix (ECM), which affects cell proliferation, migration, and differentiation. This study investigated the effect of hypoxia alone and in combination with ECM compounds and nutrition on MMP‐2...
