  abstract = {In this study, we show that LIM kinase 1 (LIMK1), a critical regulator
    of actin dynamics, plays a regulatory role in tumor cell invasion.
    We found that the level and activity of endogenous LIMK1 is increased
    in invasive breast and prostate cancer cell lines in comparison with
    less invasive cells. Overexpression of LIMK1 in MCF-7 and in MDA-MB-231
    human breast cancer cell lines increased their motility, whereas
    the specific ROCK and Rho inhibitors Y-27632 and C3, respectively,
    attenuated this effect. In addition, inhibition of LIMK1 activity
    in the MDA-MB-231 cells by expression of dominant-negative LIMK1
    resulted in decreased motility and formation of osteolytic bone lesions
    in an animal model of tumor invasion. This study shows an important
    role for LIMK1 signaling in invasion of cancer, demonstrating its
    potential as a therapeutic molecular target to decrease metastasis.},
