Neurobiology of Disease, 2020 Mutations in APP (amyloid precursor protein), PSEN1 (presenilin 1) or PSEN2 (presenilin 2) are the main cause of early-onset familial forms of Alzheimer's disease (autosomal dominant AD or ADAD).

In Silico Structure‐Guided Design of Peptide Candidates Targeting γ‐Secretase Subunit Assembly
Proteins: Structure, Function, and Bioinformatics, EarlyView.ABSTRACT The γ‐secretase complex is a membrane‐embedded protease essential for intramembrane cleavage of substrates such as Notch receptors and the amyloid precursor protein (APP), processes central to cancer progression and Alzheimer's disease (AD) pathology.

Small, EarlyView.We present a pathology‐responsive, activity‐based prodrug strategy that tackles multiple hallmarks of Alzheimer's disease (AD). Rationally designed BE compounds convert under oxidative stress into redox‐active aminophenols, neutralizing ROS and redirecting both metal‐free and metal‐bound Aβ aggregation.

Brain Pathology, EarlyView.Neuritic plaques increase in the intermediate stage of Alzheimer's neuropathological change. The intermediate stage of Alzheimer's disease was investigated by transcriptomics and immunohistochemistry. This revealed that inflammasome sensors NLRP1, NLRP3, and AIM2 oligomerize with ASC speck to form the inflammasome complex and initiate the downstream ...

Proteostasis of organelles in aging and disease
The FEBS Journal, EarlyView.Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...

Bidirectional regulation of Aβ levels by Presenilin 1 [PDF]
Proceedings of the National Academy of Sciences, 2017 Significance Alzheimer’s disease is the most common neurodegenerative disorder, affecting more than 5 million people in the United States. Multiple lines of evidence suggest that the accumulation of toxic oligomers and aggregates of β-amyloid (Aβ) peptide are the primary causes of neurodegeneration.

Journal of Pharmacological Sciences, 2006 Presenilin 1 (PS1) is a multifunctional protein, and its mutations are highly related to familial Alzheimer’s disease (AD). In this study, we examined the effects of PS1 overexpression on neuronal morphology using SH-SY5Y cells.

Mitophagy in skeletal muscle: Impact of ageing, exercise and disuse
Experimental Physiology, EarlyView.Abstract Skeletal muscle plays an important role in whole‐body health, quality of life and regulation of metabolism. The maintenance of a healthy mitochondrial pool is imperative for the preservation of skeletal muscle quality and is mediated through mitochondrial quality control consisting of mitochondrial turnover mediated by a balance between ...

The Role of Presenilin-1 in the Excitotoxicity of Ethanol Withdrawal [PDF]
The Journal of Pharmacology and Experimental Therapeutics, 2016 Presenilin-1 (PS1) is a core component of γ-secretase that is involved in neurodegeneration. We have previously shown that PS1 interacts with a mitogen-activated protein kinase [(MAPK) jun-NH2-terminal-kinase], and another MAPK (p38) is activated by ethanol withdrawal (EW), abrupt termination from chronic ethanol exposure.

Stem Cell Research, 2017 Alzheimer's disease (AD) is one of the most common neurodegenerative disorders. Previous studies have identified mutations in several genes, such as amyloid precursor protein (APP), presenilin-1 (PSEN1), and presenilin-2 (PSEN2), in patients with early ...
