In neurons, ERK1/2 and PPARγ signaling pathways were activated by MgT treatment, which in turn suppressed (by >80%) the expression of APH-1α/-1β, which is responsible for the deposition of Aβ and potentially contributes to the memory deficit that occurs in AD.
Then, Aβ 1-42 is the Aβ precursor protein derivative that up-regulates the expression of β-secretase, and c-jun N-terminal kinase (JNK)/c-Jun and ERK1/2 are involved.
