Fig. 4 B. The right-hand column is a magnified image of CDC5L from the indicated area. Scale bar: 20 μm. (B) Schematic of the minigene assay. The white boxes represent exons and the black lines between the boxes represent introns. Arrows indicate the position of the primers used in the assay. (C) RT-PCR analysis of different minigene splicing from control, Ipo9 and Exp6 siRNA-treated NIH3T3 cells. The order of the used minigenes (SMN1, SMN2, RPGR wt, RPGR −2C and RPGR −6C) is indicated in the figure. The minigene mRNA products are indicated on the left. Quantification from three independent experiments as mean±s.d. percentage of exon inclusion is shown underneath the images. Significant differences between indicated samples are marked with asterisks: SMN2: control siRNA and Ipo9 siRNA ( P =0.03), RPGR −2C: control siRNA and Ipo9 siRNA ( P =0.02) and control siRNA and Exp6 siRNA ( P =0.04).

Figure Lengend Snippet: Actin associates with RNA splicing factors and the disturbance of nuclear actin dynamics affects alternative mRNA splicing of different minigenes. (A) Confocal microscopy images of a BiFC assay between different splicing factors and actin. Tetracycline-induced HA–GFP1-10–actin U2OS cells transiently transfected with the indicated Flag–GFP11 constructs. Data shown as in Fig. 4 B.
