Role of Oxidative Stress Markers F2-Isoprostanes and Presenilin-1 in Clinical Diagnosed Alzheimer’s Diseases [PDF]

open access: yesJournal of Pharmacy and Bioallied Sciences
Introduction: Alzheimer’s disease (AD), a neurodegenerative disorder closely associated with aging, is characterized by progressive cognitive decline and is a leading cause of dementia worldwide.

Presenilin 1 Modulates Acetylcholinesterase Trafficking and Maturation. [PDF]

open access: yesInt J Mol Sci, 2023
In Alzheimer’s disease (AD), the reduction in acetylcholinesterase (AChE) enzymatic activity is not paralleled with changes in its protein levels, suggesting the presence of a considerable enzymatically inactive pool in the brain. In the present study, we validated previous findings, and, since inactive forms could result from post-translational ...

Presenilin 1 deficiency impairs Aβ42-to-Aβ40- and angiotensin-converting activities of ACE [PDF]

open access: yesFrontiers in Aging Neuroscience, 2023
IntroductionAlzheimer’s disease (AD) is associated with amyloid β-protein 1-42 (Aβ42) accumulation in the brain. Aβ42 and Aβ40 are the major two species generated from amyloid precursor protein.

Generation and deposition of Aβ43 by the virtually inactive presenilin‐1 L435F mutant contradicts the presenilin loss‐of‐function hypothesis of Alzheimer's disease

open access: yesEMBO Molecular Medicine, 2016
As stated by the prevailing amyloid cascade hypothesis, Alzheimer's disease (AD) is caused by the aggregation and cerebral deposition of long amyloid‐β peptide (Aβ) species, which are released from a C‐terminal amyloid precursor protein fragment by γ ...

Role of Presenilin-1 in Aggressive Human Melanoma. [PDF]

open access: yesInt J Mol Sci, 2022
Presenilin-1 (PS-1), a component of the gamma (γ)-secretase catalytic complex, has been implicated in Alzheimer’s disease (AD) and in tumorigenesis. Interestingly, AD risk is inversely related to melanoma, suggesting that AD-related factors, such as PS-1, may affect melanomagenesis. PS-1 has been shown to reduce Wnt activity by promoting degradation of

High-intensity interval training combined with cannabidiol supplementation improves cognitive impairment by regulating the expression of apolipoprotein E, presenilin-1, and glutamate proteins in a rat model of amyloid β-induced Alzheimer’s disease [PDF]

open access: yesIranian Journal of Basic Medical Sciences
Objective(s): Alzheimer’s disease (AD) is a major public concern and one of the primary types of dementia characterized by memory impairment and cognitive decline.

A Review Article on Oxidative Stress Markers F2-Isoprostanes and Presenilin-1 in Alzheimer’s Disease

open access: yesJournal of Pharmacy and Bioallied Sciences
Amyloid-beta plaque and tau tangle buildup lead to Alzheimer’s disease (AD), a brain disorder that causes ongoing mental decline. More and more studies show that oxidative stress plays a crucial role in how AD develops and progresses. This review focuses

Effects of presenilin-1 familial Alzheimer’s disease mutations on γ-secretase activation for cleavage of amyloid precursor protein [PDF]

open access: yesCommunications Biology, 2023
Gaussian accelerated molecular dynamics (GaMD) simulations and biochemical experiments in E.Coli provide mechanistic insight into how Presenilin-1 familial Alzheimer’s disease mutations affect structural dynamics and enzyme-substrate interactions of γ ...
