FIGURE 5:
N-WASP does not participate in RhoD-induced protrusion formation. (A) Neither N-WASP nor a dominant-negative N-WASP affects RhoD-induced protrusion formation. The 10T1/2 cells were cotransfected with mCherry–RhoD(G26V) (green) and EGFP–N-WASP or EGFP–N-WASP(ΔVCA) (magenta) and analyzed 48 h after the transfection. (B) Ratio of the cells extending thin and long protrusions in the analysis of (A). The values are mean ± SD of three independent experiments. *, p < 0.001 by t test compared with respective mock transfection (control). (C) Knockdown of N-WASP does not interfere with RhoD-induced protrusion formation. C2C12 myoblast clones stably expressing control and N-WASP siRNAs were transfected with EGFP–RhoD(G26V) and analyzed 48 h after the transfection. Scale bars: 10 μm. (D) Ratio of the cells extending thin and long protrusions in the analysis of (C). The values are mean ± SD of three independent experiments. *, p < 0.001 by t test compared with respective mock transfection (control).
