Abstract

Cancer cell invasion is a critical phenomenon in cancer pathogenesis. Glycogen synthase kinase-3β (GSK-3β) has been reported to regulate cancer cell invasion both negatively and positively. Thus, the net effect of GSK-3β on invasion is unclear. In this report, we showed that GSK-3β inhibitors induced dysregulation of the actin cytoskeleton and functional insufficiency of focal adhesion, which resulted in suppressed invasion. In addition, WAVE2, an essential molecule for actin fibre branching, was down-regulated after GSK-3β inhibition. Collectively, we propose that the WAVE2-actin cytoskeleton axis is an important target of GSK-3β inhibitors in cancer cell invasion.
