FIG. 6.
Effects of membrane-targeted PAK on the negative guidance response. Neurite outgrowth in cells transfected with αPAK-CAAX (A and B) or αPAK-CAAX KD (C and D). Stained with phalloidin (A and C) or anti-HA (B and D). Neurites of cells transfected with αPAK-CAAX (E) or with αPAK-CAAX KD (F) crossing a laminin/CSPG boundary. HA-tagged cells are shown. (G) Neurites of cells transfected with either PAK construct have an increased ability to cross from laminin onto CSPG. Results are for three independent experiments (n = 6 for controls, n = 8 for αPAK-CAAX-transfected cells, and n = 14 for αPAK-CAAX KD-transfected cells).
