FIG 6.

Effects of PAK1 siRNA (A) or CtBP1-S158A mutant (B) on the levels of myogenin (upper panel) and AChRα (lower panel) mRNA in denervated tibialis anterior muscle, as detected by RT-PCR. In each panel the left column shows the data for a control (innervated muscle electroporated with scramble siRNA in panel A; innervated muscle in panel B), the middle column shows the effect of denervation (including electroporation with Scramble siRNA in panel A), and the right column shows the effect of PAK1 siRNA electroporation in denervated muscle (A) or the effect of CtBP1-S158A overexpression in denervated muscle (B).
