Cytoskeletal changes in persistently activated cells. (A–D) AX2 and pten− cells expressing the indicated constructs and F-actin probe RFP-LimEΔcoil. RasCQ62L expression changes the dynamics of F-actin waves, producing a persistent band of peripheral staining in pten− cells. (Scale bars: A–C, 5 μm; D, 4 μm.) (E–H) Respective kymographs of cells in A–D. (I) High-resolution images of actin probe LimE in parental pten− (Left) and RasCQ62L/pten− (Right) cells. Top shows a view of the ventral surface; Bottom shows a side profile. (Scale bars: 5 μm.) (J) Intermediate-wave F-actin wave pattern (GFP-LimEΔcoil) phenotypes induced by RasCQ62L expression in pten− cells. (Scale bars: 5 μm.) Dox, doxycycline.
