doi: 10.1371/journal.pone.0180657

Figure Lengend Snippet: Clone 11 NSC-34 cells harboring a reporter gene driven by the 3.4-kb SMN2 promoter were treated with 1 μM D156844, D158872, D157161, D157495 or DMSO (n = 4/drug) for 19 hours prior to fluorescent β-lactamase assay analysis. (A) All 4 compounds significantly increased SMN2 -drived BLA activity. The asterisk (*) denotes a statistically significant (p ≤ 0.05) difference between drug- and vehicle-treated cells. Dose-response curves (1 nM– 10 μM) for D156844 (B) , D158872 (C) , D157161 (D) and D157495 (E) . Each compound tested exhibited a dose-dependent increase in SMN2 -drived BLA activity.

Article Snippet: The clone 11 cell line (Vertex Pharmaceuticals, [ ]) was used for the SMN2 promoter assay and the clone 5.3 (Vertex Pharmaceuticals, [ ]) was used for the SMN2 splicing assay.

Figure Lengend Snippet: (A) Clone 5.3 NSC-34 cells harbor a reporter gene whose expression is linked to inclusion of SMN2 exon 7. These cells were treated with 1 μM D156844, D158872, D157161, D157495 or DMSO (n = 4/drug) for 19 hours prior to fluorescent β-lactamase assay analysis. These compounds tested did not increase the inclusion of SMN2 exon 7 but D157161 and D157495 actually decreased SMN2 exon 7 inclusion. The asterisk (*) denotes a statistically significant (p ≤ 0.05) difference between drug- and vehicle-treated cells. (B) Qualitative analysis of the effects of D156844, D157161, D158872 and D157495 on SMN2 transcripts in type II SMA fibroblasts. GM03813 cells were treated with 1 μM each compound or DMSO (n = 3/compound) for 5 days and then analyzed for changes in the amounts of FL-SMN and SMNΔ7 transcripts by RT-PCR and agarose gel electrophoresis. The amounts of FL-SMN and SMNΔ7 transcripts were also compared against GM03814 samples. COL3A transcripts were also assayed as a loading control for RT-PCR. These compounds tested did not affect the proportion of FL-SMN relative to SMNΔ7 .
