To unravel the growth inhibition mechanism of Polo-like kinase 3 (Plk3), the effect of overexpression of Plk3 was examined in 293T cells. Cell rounding, changes in actin organization and cellular detachment were induced by Plk3 transfection in a kinase activity-dependent manner. Although apoptosis was not observed, Plk3 overexpression suppressed cellular growth in a long-term colony-forming assay. Because both Plk3 and Ras affect F-actin organization, the effect of co-transfection of Plk3 and Ras was evaluated. Adhesion was synergistically lost by co-transfection of these two genes, compared with transfection of Plk3 alone. Furthermore, overexpression of Plk3 caused long-term growth suppression in Ras-transformed NIH3T3. Collectively, Plk3 activation might cause cytoskeleton re-organization and result in growth suppression more pronouncedly in Ras pathway-activated cells.
