Fig 5A. Quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR) showing bmp4 expression in untreated wildtype and bmp4^st72/st72 homozygous larvae at 1 day post fertilization (dpf). RNA was extracted at 1 dpf from untreated, pooled wildtype EKW larvae and bmp4^st72/st72 homozygous larvae. After cDNA synthesis, qRT-PCR was performed and analyzed using the ΔΔCt method and eef1a1l1 as an internal control gene. The results, plotted as relative quantity (RQ) normalized to bmp4 expression in wildtype EKW larvae at 1.0 show increased bmp4 expression in bmp4^st72/st72 homozygous larvae (p = 0.014), consistent with bmp4 RNA available for rescue using nonsense suppression therapy. All values are an average of 3 replicates and 3 biological replicates were performed for each experiment. The error bars indicate the standard error (SE) of the mean. Fig 5B. Quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR) showing bmp4 expression in incrossed bmp4^st72/+ heterozygous larvae treated with 0 μM PTC124 and incrossed bmp4^st72/+ heterozygous larvae treated with 0.5 μM PTC124 from 6–8 hours post fertilization (hpf). RNA was extracted at 3 days post fertilization (dpf) from pooled larvae treated with 0 μM PTC124 and larvae that had been treated with 0.5 μM PTC124 from 6–8 hpf. After cDNA synthesis, qRT-PCR was performed and analyzed using the ΔΔCt method and eef1a1l1 as an internal control gene. The results, plotted as relative quantity (RQ) normalized to bmp4 expression (1.0) in incrossed, bmp4^st72/+ heterozygous larvae that were treated with 0 μM PTC124 show a non-significant increase in bmp4 expression in incrossed, bmp4^st72/+ heterozygous larvae treated with 0.5 μM PTC124 (p = 0.09). All values are an average of 3 replicates and 3 biological replicates were performed for each experiment. The error bars indicate the standard error (SE) of the mean.
