タイトル Modulation of matrix metalloproteinase-9 secretion from tumor-associated macrophage-like cells by proteolytically processed laminin-332 (laminin-5).
ジャーナル Clin Exp Metastasis
Abstract Macrophages infiltrating tumor tissues (tumor-associated macrophages, TAM) affect the malignant behaviors of tumor cells. We previously reported that monocytes were differentiated into TAM-like cells secreting matrix metalloproteinase (MMP)-9 by co-culture with tumor cells, and that cell adhesion to extracellular matrix (ECM) proteins played a critical role in the differentiation. In this study, we found that the monocyte differentiation was promoted by laminin-332 (laminin-5), a major epithelial ECM component. We also demonstrated that the proteolytic processing of the γ2 chain of laminin-332 was essential for its activity but that the N-terminal short arm of the γ2 chain inhibited MMP-9 secretion. These results indicate that the activity of laminin-332 for monocyte differentiation is dynamically regulated by the proteolytic processing of the γ2 chain.
