In the experiment to test the neuroprotective effects of FB on APP/PS1 mice, Li et al. demonstrated that FB exerted anti-AD effects both in vivo and in vitro, and the in vitro experiment revealed that cells treated with FB had elevated levels of both AKT and β-catenin signaling (Li Y. H. et al., 2021). The gene discussed is PSEN1; the disease is Alzheimer disease.
