The ability of cancer cells to traffic through the extracellular matrix relies on the action of the membrane-anchored matrix metalloprotease MT1-MMP. MT1-MMP is exocytosed to invadopodia, the actin-based membrane protrusions responsible for matrix degradation. The small GTP-binding protein ARF6 is known to coordinate post-endocytic recycling and actin cytoskeletal organization at the plasma membrane and was shown to be up-regulated in breast cancer cells. In my PhD work I showed that ARF6 and two of its effectors JIP3 and JIP4 are required for MT1-MMP endosomes intracellular positioning and exocytosis at invadopodia and consequently for tumor cells ability to remodel the matrix and invade through a three-dimensional matrix environment. ARF6...
