Geniposide-mediated protection against amyloid deposition and behavioral impairment correlates with downregulation of mTOR signaling and enhanced autophagy in a mouse model of Alzheimer's disease

Figure 8. Geniposide treatment decreases mTOR activation markers in brains of APP/PS1 mice. Hippocampal expression of Akt, mTOR, and 4E-BP1, and their respective phosphorylated forms was detected by western blot. The expression of p-Akt (A) and p-mTOR (B) was enhanced in APP/PS1 mice compared to WT, and geniposide attenuated this increase. The expression of p-4E-BP1 (C) in APP/PS1 mice was reduced compared to WT, and geniposide partly restored this decrease. Data are presented as mean ± SEM (n = 6). ***p < 0.001, **p < 0.01, *p < 0.05 vs. WT; #p < 0.05 vs. APP/PS1 mice (one-way ANOVA, Tukey's Multiple Comparison Test). WT: wild-type mice. GP: geniposide.
