abstract = {Alzheimer's disease (AD) is characterized by two
neuropathological hallmarks: senile plaques, which are
composed of amyloid-β (Aβ) peptides, and neurofibrillary
tangles, which are composed of hyperphosphorylated tau
protein. Aβ peptides are derived from sequential
proteolytic cleavage of the amyloid precursor protein (APP).
In this study, we identified a so far unknown mode of
regulation of APP protein synthesis involving the MID1
protein complex: MID1 binds to and regulates the translation
of APP mRNA. The underlying mode of action of MID1 involves
the mTOR pathway. Thus, inhibition of the MID1 complex
reduces the APP protein level in cultures of primary
neurons. Based on this, we used one compound that we
discovered previously to interfere with the MID1 complex,
metformin, for in vivo experiments. Indeed, long-term
treatment with metformin decreased APP protein expression
levels and consequently Aβ in an AD mouse model.
Importantly, we have initiated the metformin treatment late
in life, at a time-point where mice were in an already
progressed state of the disease, and could observe an
improved behavioral phenotype. These findings together with
our previous observation, showing that inhibition of the
MID1 complex by metformin also decreases tau
phosphorylation, make the MID1 complex a particularly
interesting drug target for treating AD.},
