Proteolytic and non-proteolytic migration of tumour cells and leucocytes.
The migration of different cell types, such as leucocytes and tumour cells, involves cellular strategies to overcome the physical resistance of three-dimensional tissue networks, including proteolytic degradation of extracellular matrix (ECM) components. High-resolution live-cell imaging techniques have recently provided structural and biochemical insight into the differential use of matrix-deg...
متن کاملBilayer Membrane Modulation of Membrane Type 1 Matrix Metalloproteinase (MT1-MMP) Structure and Proteolytic Activity
Cell surface proteolysis is an integral yet poorly understood physiological process. The present study has examined how the pericellular collagenase membrane-type 1 matrix metalloproteinase (MT1-MMP) and membrane-mimicking environments interplay in substrate binding and processing. NMR derived structural models indicate that MT1-MMP transiently associates with bicelles and cells through distinc...
متن کاملThe protease MT1-MMP drives a combinatorial proteolytic program in activated endothelial cells.
The mechanism by which proteolytic events translate into biological responses is not well understood. To explore the link of pericellular proteolysis to events relevant to capillary sprouting within the inflammatory context, we aimed at the identification of the collection of substrates of the protease MT1-MMP in endothelial tip cells induced by inflammatory stimuli. We applied quantitative pro...
متن کاملProteolytic and non-proteolytic regulation of collective cell invasion: tuning by ECM density and organization
Cancer cells manoeuvre through extracellular matrices (ECMs) using different invasion modes, including single cell and collective cell invasion. These modes rely on MMP-driven ECM proteolysis to make space for cells to move. How cancer-associated alterations in ECM influence the mode of invasion remains unclear. Further, the sensitivity of the two invasion modes to MMP dynamics remains unexplor...
متن کاملShedding of RANKL by tumor-associated MT1-MMP activates Src-dependent prostate cancer cell migration.
Membrane type 1 matrix metalloproteinase (MT1-MMP) plays an essential role in protease-mediated extracellular matrix (ECM) degradation, but it also functions as a sheddase releasing non-ECM substrates such as receptor activator of NF-kappaB ligand (RANKL), an osteoclastogenic factor typically confined to the surface of osteoblasts. We previously found high expression of MT1-MMP in skeletal meta...
