Reintroduction of ROCK1 rescues the miR-124-induced invasion inhibition.

(A) Stress fiber staining in U87MG glioma cells treated with miR-124 expression vector along with p160^ROCKΔ3 or control pCAG-myc (Scale bars: 20 µm). (B) Scanning electron microscopy of U87MG cells. (C) In vitro invasion assay. Invasive cells were stained and the average number of cells was counted at random six fields of vision. The data was an average value of three independent experiments. (Magnification: 100×; scale bars: 100 µm).
