Fig. 3. RNA interference of components of the COG complex. Schematic diagrams of the COG complex in mammals (A) and C. elegans (B). Nomarski images of the posterior gonad arms of animals treated with RNAi directed against cogc-1 (C), cogc-2 (D), cogc-3 (E) or cogc-4 (F). Anterior is leftwards. Dorsal is towards the top. Scale bar: 25 µm. The migration paths of DTCs are depicted by orange lines and arrowheads. (G) Percentages of anterior and posterior gonad arms with DTC migration defects in RNAi knockdowns of COG components in the wild-type background. n=30 for each experiment. The following cDNAs were used for RNAi analysis of COG complex components: yk31b12 corresponds to cogc-1; yk324g6 to C06G3.10/cogc-2; yk863b10 to cogc-3; yk402e5 to Y51H7C.6/cogc-4; yk621c10 to C43E11.1/cogc-5; yk29e8 to K07C11.9/cogc-6; yk730h8 to W01B6.9/cogc-7; and yk26e9 to R02D3.2/cogc-8. The error bars represent the mean±s.d. The values were calculated from the data collected from the first and second half of the animals examined.
