Figure 5. Foxs and ESRPs promote switching from exon 9 to exon 8.

(A)RT-PCR from HeLa cell transfected the wild-type reporter and indicated cDNA expression vectors with or without Fox2 siRNA. The bar graph shows the amount of each splicing product. (B) Fluorescent microscopy image of HeLa cell transfected the wild-type reporter with indicated cDNA expression vectors (scale bar = 200 µm).
