Figure 3: Biological activity of 1 in DM2 patient-derived fibroblasts.

Figure 3:

(A) Representative microscopic images for the reduction of nuclear foci by 1, as completed by RNA-FISH and immunohistochemistry using an anti-MBNL1 antibody. (B) Quantification of r(CCUG)exp-MBNL1 foci/nucleus (n = 3 biological replicates, 40 nuclei counted per replicate). (C) Effect of 1 on IR pre-mRNA splicing regulated by MBNL1. (D) Effect of 1 on CNBP pre-mRNA splicing. (E) Effect of 1 on an MBNL1-regulated alternative splicing event, IR exon 11, as determined by RT-PCR; (F) Effect of 1 on aberrant CNBP pre-mRNA splicing caused by r(CCUG)exp, as determined by RT-PCR; that is, retention of intron 1; (G) Effect of 1 on total intron 1 levels and CNBP mature mRNA, as determined by RT-qPCR. Error bars represent SD. *P < 0.5, **P < 0.01, ***P < 0.001, ****P < 0.0001, as determined by a one-way ANOVA (n = 3). See also Figure S2.
