doi: 10.7554/eLife.61669
Figure Lengend Snippet: ( A–B ) Western blot analysis of ( A ) AKAP6 or ( B ) PCM1 expression levels upon siRNA-mediated depletion of AKAP6. Loading control: α-tubulin. ( C ) Immunostaining of nesprin-1α (green), AKAP6 (red), and DNA (DAPI) in siControl- or si-AKAP6-depleted P3 cardiomyocytes. ( D ) Quantification of C as nuclear intensity normalized to the mean intensity in siControl. Error bars represent SD. Statistical test: two-way ANOVA with post-hoc Bonferroni comparison. **** p<0.0001, n.s.: no significance. n = 70, 83, 66, 98 (from left to right), data are from two independent experiments. ( E–H ) Immunostaining of ( E ) Pcnt (red) or ( G ) AKAP9 (red), cardiac troponin I (magenta, cardiomyocyte-specific), and DNA (DAPI) in AKAP6-depleted P3 cardiomyocytes transfected with an siRNA-resistant silent mutant of AKAP6 fused to GFP (AKAP6res-GFP). Transfected cells are denoted with a green arrowhead. ( F–H ) Quantification of E and G respectively, as nuclear intensity normalized to the mean intensity in siControl. Error bars represent SD. Statistical test: two-way ANOVA with post-hoc Bonferroni comparison. **** p<0.0001, n.s.: no significance. ( F ) n = 100 per condition, ( H ) n = 128, 133, 112 (from left to right), data are from three independent experiments. Scale bars: 10 µm.
