Figure Lengend Snippet: Effects of SKAP2 RNAi on ARP2 and WAVE2 expression. (A) Subcellular localization of ARP2 after SKAP2 siRNA injection. ARP2 was mainly distributed at the membrane in the control oocytes, whereas ARP2 expression was barely detectable in the siRNA-injected group. Green: ARP2; blue: chromatin. Bar = 20 μm. (B) Localization of WAVE2 after SKAP2 siRNA injection. WAVE2 was expressed around the spindle, whereas no specific localization of WAVE2 was observed around spindle in the siRNA-injected group. Red: WAVE2; blue: chromatin. Bar = 20 μm. (C) The fluorescence intensity of ARP2 in the SKAP2 siRNA-injected oocytes was decreased. (D) The fluorescence intensity of WAVE2 in SKAP2 siRNA-injected oocytes was significantly reduced. (E) ARP2 expression was reduced after SKAP2 siRNA injection by western blotting examination, as the relative intensity of ARP2 protein was significantly decreased.
