Figure 3. Low-dose salsalate-mediated inhibition of p300/CBP acetyltransferase protects mice from post-TBI-induced elevated ac-tau, AIS degradation, tau mislocalization, neurodegeneration, and cognitive deficits.
(A) Low-dose salsalate dose-dependently reduces post-TBI elevations in ac-tau in the brain (n = 3, *p < 0.05, **p < 0.01, ***p <0.001 versus TBI-+Vehicle group, one-way ANOVA; and Tukey’s post hoc analysis).
(B) Low-dose salsalate protects mice from post-TBI AIS degradation (scale bar, 5 μm).
(C) Low-dose salsalate protects mice from post-TBI tau mislocalization (scale bar, 5 μm).
(D) Low-dose salsalate protects mice from post-TBI axonal degeneration (scale bar, 5 μm). In (BHD), each group n = 3, *p < 0.05, **p < 0.01, ***p <0.001, ****p < 0.0001 versus TBI+Vehicle group, one-way ANOVA and Tukey’s post hoc analysis.
(E) Low-dose salsalate protects mice from post-TBI impairments in motor (foot slip assay) and cognitive (learning and memory in the Bames maze) behavioral assays. (*p < 0.05, **p < 0.01, ***p<0.001, ****p < 0.0001 versus TBI+vehicle group, repeated-measures two-way ANOVA (learning) and one-way ANOVA (memory) and Tukey’s post hoc analysis.
