Regulating the Conversion between Rounded and Elongated Modes of Cancer Cell Movement

Switching between elongated and rounded modes of movement allows invasive tumor cells to adapt to varying microenvironments. In a recent issue of Cell, Sanz-Moreno et al. identify DOCK3, NEDD9, WAVE2, and ARHGAP22 as key molecules regulating Rac and Rho signaling that determine the mode of movement driving melanoma cell metastasis.
