RTP801 silencing in the R6/1 mouse hippocampal neurons reduces the levels of the inflammasome components. (a) Immunoblottings for NLRP1, cleaved NLRP1, procaspase 1, cleaved caspase 1, ASC/TMS1, and GFP as loading control for transduced neurons in the dorsal hippocampus of 4.5-month-old WT shCt, WT shRTP801, R6/1 shCt, and R6/1 shRTP801 mice. (b–f) Densitometric quantification of NRLP1 (treatment effect: F(1, 26) = 24.89, p < 0.0001; interaction: F(1, 26) = 1.175, p = 0.2883), cleaved NLRP1 (treatment effect: F(1, 29) = 44.18, p < 0.0001; genotype effect: F(1, 29) = 15.32, p = 0.0005; interaction: F(1, 29) = 6.588, P = 0.0157), ASC/TMS1 (treatment effect: F(1, 31) = 40.72, p < 0.0001; genotype effect: F(1, 31) = 17.85, p = 0.0002; interaction: F(1, 31) = 15.91, p = 0.0004), procaspase 1 (treatment effect: F(1, 30) = 26.06, p < 0.0001; interaction: F(1, 30) = 10.82, p = 0.0026) and cleaved caspase 1 (treatment effect: F(1, 30) = 25.57, p < 0.0001; interaction: F(1, 30) = 5.551, p = 0.0252) as in (a) for the hippocampus. Densitometric quantification of all proteins is expressed as the mean ± SEM. All data were analyzed by two-way ANOVA followed by Bonferroni’s post hoc test. * p < 0.05, ** p < 0.01, and *** p < 0.001.
