Fig 3. Cspg4 knockdown led to shorter body length.
(A) The 164 bp band indicated the skipping of exon two. (B) Cspg4 knockdown embryos showed shorter body lengths than control morpholino injected embryos at 1 dpf. The body lengths were measured by using the freehand tool in ImageJ (as labeled by the red line). (C) Cspg4 splicing blocking morpholino shortened body length in a dose-dependent manner (each dot represents one embryo; Control-MO, n = 26; 2 ng MO-e2i2, n = 78; 4 ng MO-e2i2, n = 53; 8 ng MO-e2i2, n = 67). (D) Knockdown cspg4 using translational blocking morpholino also shortened body length at 1 dpf (control-MO, n = 140; 1 ng MO-start, n = 60; 2 ng MO-start, n = 139; 4 ng MO-start, n = 105). (E) Combining ineffective doses of cspg4 MO-e2i2 and MO-start shortened the body length at 1 dpf (control-MO, n = 103; 1 ng MO-start +1 ng MO-e2i2, n = 67). In panel (C and D) the significant difference between groups were tested by ANOVA followed by Tukey’s multiple comparison. Different letters (a, b or c) indicate a significant difference between groups (p ≤ 0.05). Student’s t-test was used to analyze data in panel (E). ** indicates p ≤ 0.01. Data are presented as mean ± SD. Scale bar represents 0.5 mm.
