MetabolomicsAnalyzing nicotine action against amyloid toxicity by NMR-pharmacometabolomics: an exploratory study

Alzheimer's disease (AD) is the primary neurodegenerative disease spread worldwide. One of the main histopathological hallmarks of AD is amyloid plaque deposition in the brain. Despite some epidemiological studies demonstrating that cigarette smoke is a factor in predisposing people to AD, nicoti...

ProteomicsProteomic and unbiased post-translational modification profiling of amyloid plaques and surrounding tissue in a transgenic mouse model of Alzheimer’s disease
Amyloid plaques (Aβ plaques) are one of the hallmarks of Alzheimer’s disease (AD). The main constituent of Aβ plaques is beta-amyloid peptides but a complex interplay of other infiltrating proteins also co-localizes. We focused on proteomic differences between Aβ plaques and adjacent control tissue ...

TranscriptomicsModulation of gene expression by complement protein C1q in amyloid-beta injured neurons
Complement protein C1q is induced after injury in the brain and during Alzheimer's disease and has been shown to protect against amyloid-beta induced neuronal death. In this study, we used microarray approach to identify the pathways modulated by C1q that are associated with neuroprotection. Immatur...

TranscriptomicsExpression profiling of laser-microdissected tissue from APPPS1 plaque-depositing mouse model of Alzheimer's disease
Amyloid-M-CM-^_ (AM-CM-^_) plaques are pathological hallmarks of Alzheimer disease. However, the precise neuropathological changes that occur in brain in response to amyloid deposition are largely unknown. To study the molecular mechanism(s) responsible for AM-CM-^_-mediated neuropathology, we perfo...

ProteomicsQuantitative proteomic characterization of senile plaques from Alzheimer's disease and non-demented brain
The deposition of amyloid senile plaques (SPs) play a central role in Alzheimer’s disease (AD), but the mechanisms by which SPs induce neural toxicity are disputed. Genetically engineered mouse models emphasising SPs have had limited success in reproducing the neuropathology of AD, and have also fai...

ProteomicsImpaired presynaptic proteostasis in the initial stages of amyloid beta proteotoxicity
Compromised protein homeostasis underlies accumulation of plaques and tangles in Alzheimers disease (AD); however, little is known about the early mechanisms that contribute to this accumulation. To objectively assess the impaired protein turnover at early stages of amyloid beta (Abeta) proteotoxic...

The amyloid precursor protein (APP) plays a central role in the pathogenesis of Alzheimerâ??s disease (AD). Processing of APP by β- and γ-secretase activities results in the production of Ã?-amyloid (AÃ?), the main constituent of Alzheimer plaques, but also in the generation of the APP intracellul...
