SQSTM1 and Alzheimer disease: The results revealed that PA treatment led to a decrease in P62 (n = 6, 76.69% ± 3.64%, p = 0.001 vs. CTR; Figures 4A,B) levels and LC3 II/I ratios (n = 5, 75.19% ± 6.91%, p = 0.072 vs. CTR; Figures 4A,C), suggesting that PA may enhance autophagy function in AD model cells.
