Figure Lengend Snippet: Figure 2. The excess of CPBA and ammonia in the brain is associated with hippocampal synapse loss in aging rodents (A‒D and I‒L) The percentages of CPBAs and ammonia level as well as the CPBA composition (e.g., taurocholic acid [TCA]) in the brain of rodents in both genders (n = 6–8/group). (E, F, M, and N) The representative images and counts of hippocampal synapses in rats and mice resulted from transmission electron microscopy (n = 6–8/group, 3 repeats/sample). (G and O) The concentrations of hippocampal Synapsin 1 (Syn1) in both genders of rodents (n = 68/group, 3 repeats/sample). (H and P) Pearson’s r correlation between hippo- campal Syn1 level and brain TCA or ammonia in rodents. The comparisons of CPBA, ammonia, and synapse data in rodents were performed with two-way ANOVA. The statistical difference is labeled as follows: ***p < 0.005 vs. 24-week female (F24); ##p < 0.01; ###p < 0.005 vs. 24-week male (M24); $$p < 0.01 vs. 111-week male (M111) for the comparison of the CBPA composition among groups; *p < 0.05; **p < 0.01; ***p < 0.001 for other comparisons.
