Fig. 4: Cdc42 regulates F-actin aggregation in the cell front of CRC cells.

a Immunofluorescence images of F-actin expression in CRC cells. Scale bar, 5 μm. CA = Cdc42V12, the constitutively active form of Cdc42. b Western blotting analysis shows LIMK2, p-LIMK2, cofilin, p-cofilin, and F-actin expression in CRC cells cultured in different conditions.
