Figure 9. Redirected calcineurin A splicing in adult FDB muscle.
(A) Confirmation of redirected splicing in adult FDB muscle by RT-PCR. ASO morpholinos were administered to the FDB muscle (Figure 8—figure supplement 2). (B) RT-PCR of targeted (calcineurin A) and control (Atp2a1, Cacna1s, Prkca, and Ppp1r12b) splicing events. Single asterisk (*) denotes p<0.05, *** denotes p<0.001, and n.s. denotes no statistical difference by student T-test, n = 4 mice per group. Displayed are mean with SD bars. (C) Force and calcium analysis after twitch stimulus. Peak force and half relaxation time were measured for force and peak calcium for calcium. Single asterisk (*) denotes p<0.05 significance by student T-test, n = 3–4 mice per group. Displayed are mean with SD bars. (D) Force and calcium analysis after tetanus stimuli. Peak force and half relaxation time were measured for force and peak calcium for calcium. Single asterisk (*) denotes p<0.05 significance by student T-test, n = 3–4 mice per group. Displayed are mean with SD bars. (E) Relative mRNA levels of mRNAs from Nfatc target genes in FDB muscle by RT-PCR. Single asterisk (*) denotes p<0.05 and marked are transcriptional targets nearing significance by student T-test, n = 3 mice per group. Displayed are mean with SD bars.
