“…The transition to amoeboid motility (mesenchymal‐to‐amoeboid transition; MAT), can be induced experimentally by inhibiting metalloproteinase activity [Wolf et al., 2003a,b; Kosla et al., ; Taddei et al., ], disrupting cell–substrate adhesions [Wolf et al., ; Carragher et al., ; Van Goethem et al., ; Ehrbar et al., ; Liu et al., ], inhibiting Arp2/3 complex‐dependent actin polymerisation in lamellipodia [Derivery et al., ; Bergert et al., ; Beckham et al., ], or shifting a balance between actin polymerisation‐driven protrusion and actomyosin‐dependent contractility by altering Rho‐family small GTPases activity [Sahai and Marshall, ; Sanz‐Moreno, V., ; Parri et al., ; Bergert et al., ]. Thus, it appears that under conditions unfavourable for lamellipodium formation, some tumour cells switch to amoeboid motility to bypass the inhibition which leads to greater autonomy of cell migration.…”
