LIM kinase 1 increases tumor metastasis of human breast cancer cells via regulation of the urokinase-type plasminogen activator system.

Abstract

Mammalian LIM kinase 1 (LIMK1) phosphorylates and inactivates the actin-binding and -depolymerizing factor cofilin and induces actin cytoskeletal changes. LIMK1 is reported to play an important role in cell motility, but the mechanism of induction of cell motility and the role of LIMK1 in tumor growth, angiogenesis and invasion are poorly understood.
