Figure 2Representative photomicrographs of TDP-43 (green) and NeuN (red) immunohistochemistry in hippocampal CA1 of Tardbpfx/fx and CamKIIaCRE;Tardbpfx/fx mice. Arrows denote areas of depleted TDP-43 immunoreactivity in the mutant. Percentage of TDP-43 positive cells relative to NeuN cells in CA1 and the remaining hippocampus (HC [-CA1]) of Tardbpfx/fx and CamKIIaCRE;Tardbpfx/fx mice. Results are presented as average ± SEM (N=3 mice per condition; 5 sections per mouse). **, p<0.01. Data information: Results are presented as average ± standard error of the mean (SEM). All statistical tests were performed using 2-way ANOVA with Sidak post hoc analysis. TDP-43 intensity in TDP-43/NeuN double-positive cells in CA1 and the remaining hippocampus of Tardbpfx/fx and CamKIIaCRE;Tardbpfx/fx mice. Results are presented as average ± SEM (N=3 mice per condition; 5 sections per mouse). *, p<0.05; **, p<0.01. Data information: Results are presented as average ± standard error of the mean (SEM). All statistical tests were performed using 2-way ANOVA with Sidak post hoc analysis. Expression of Tardbp mRNA in micro-dissected CA1 and the remaining hippocampus of Tardbpfx/fx and CamKIIaCRE;Tardbpfx/fx mice quantified by Q-PCR. Results are presented as average ± SEM relative to levels in Tardbpfx/fx mice, after normalization to Gapdh mRNA. (N=3 mice per condition; **, p<0.01). Data information: Results are presented as average ± standard error of the mean (SEM). All statistical tests were performed using 2-way ANOVA with Sidak post hoc analysis. Western blots of micro-dissected CA1 and the remaining hippocampus showing expression of TDP-43, full-length and truncated (soluble) Sortilin, and GAPDH in Tardbpfx/fx and CamKIIaCRE;Tardbpfx/fx mice. Bands corresponding to soluble Sortilin are indicated (black arrows). GAPDH immunoblotting was used to control for equal loading. Molecular weights are indicated in kDa. Data information: Results are presented as average ± standard error of the mean (SEM). All statistical tests were performed using 2-way ANOVA with Sidak post hoc analysis. TDP-43 expression in micro-dissected CA1 and the remaining hippocampus of Tardbpfx/fx and CamKIIaCRE;Tardbpfx/fx mice. Results are presented as average ± SD of densitometry relative to GAPDH (N=3 mice per condition; **, p<0.01). Data information: Results are presented as average ± standard error of the mean (SEM). All statistical tests were performed using 2-way ANOVA with Sidak post hoc analysis. Expression of exon 17b Sort1 and total Sort1 mRNAs in micro-dissected CA1 and the remaining hippocampus of Tardbpfx/fx and CamKIIaCRE;Tardbpfx/fx mice quantified by Q-PCR. Results are presented as average ± SD relative to levels in Tardbpfx/fx mice, after normalization to Gapdh mRNA. (N=3 mice per condition; **, p<0.01 Data information: Results are presented as average ± standard error of the mean (SEM). All statistical tests were performed using 2-way ANOVA with Sidak post hoc analysis. Expression of full-length (left) and truncated (soluble, right) Sortilin protein in micro-dissected CA1 and the remaining hippocampus of Tardbpfx/fx and CamKIIaCRE;Tardbpfx/fx mice. Results are presented as average ± SD of densitometry relative to GAPDH (N=3 mice per condition; **, p<0.01). Data information: Results are presented as average ± standard error of the mean (SEM). All statistical tests were performed using 2-way ANOVA with Sidak post hoc analysis.
