Pesticides are widely used in agriculture, and epidemiological studies suggest that pesticide exposure is a risk factor for Alzheimer's disease (AD), but the mechanisms are elusive. Here, we studied the effects of pesticide exposure on the cognitive ability and the underlying mechanisms in rats. Deltamethrin and carbofuran were administered respectively(More)
Phosphotyrosyl phosphatase activator (PTPA) is decreased in the brains of Alzheimer's disease (AD) and the AD transgenic mouse models. Here, we investigated whether down-regulation of PTPA affects cell viability and the underlying mechanisms. We found that PTPA was located in the integral membrane of mitochondria, and knockdown of PTPA induced cell(More)
Zinc induces protein phosphatase 2A (PP2A) inactivation and tau hyperphosphorylation through PP2A (tyrosine 307) phosphorylation in cells and the brain, but whether Zn2+ has a direct inhibitory effect on PP2A is not clear. Here we explored the effect of Zn2+ on PP2A and their direct interaction in vitro. The results showed that Zn2+ mimicked the inhibitory(More)
Increase of inhibitor-2 of protein phosphatase-2A [Formula: see text] is associated with protein phosphatase-2A (PP2A) inhibition and tau hyperphosphorylation in Alzheimer's disease (AD). Down-regulating [Formula: see text] attenuated amyloidogenesis and improved the cognitive functions in transgenic mice expressing amyloid precursor protein (tg2576). Here,(More)
