Endoproteolytic Cleavage and Proteasomal Degradation of Presenilin 2 in Transfected Cells [PDF]

Journal of Biological Chemistry, 1997
Mutations in the presenilin genes, PS1 and PS2, cause a major portion of early onset familial Alzheimer's disease (FAD). The biological roles of the presenilins and how their pathological mutations confer FAD are unknown. In this study, we set out to examine the processing and degradation pathways of PS2.

Alzheimer’s disease phenotypes and genotypes associated with mutations in presenilin 2 [PDF]

Brain, 2010
Mutations in presenilin 2 are rare causes of early onset familial Alzheimer's disease. Eighteen presenilin 2 mutations have been reported, although not all have been confirmed pathogenic. Much remains to be learned about the range of phenotypes associated with these mutations.

From Inflammatory Bowel Disease to Cancer: Gut Microbiota–Immune Microenvironment Crosstalk and Natural Product‐Based Therapeutic Opportunities

Cancer Nexus, EarlyView.
ABSTRACT Inflammatory bowel disease (IBD), primarily Crohn's disease and ulcerative colitis, is a chronic relapsing inflammatory disorder of the gastrointestinal tract and an important risk factor for IBD‐associated cancer. Increasing evidence suggests that gut microbiota dysbiosis, epithelial barrier dysfunction, and immune microenvironment remodeling

Metals accelerate production of the aberrant splicing isoform of the presenilin‐2 [PDF]

Journal of Neurochemistry, 2004
AbstractOxidative stress is a major risk factor for Alzheimer's disease (AD) and other neurodegenerative disorders. Metals are known to be one of the factors that contribute to oxidative stress. Recently, we reported that the aberrant splicing isoform (PS2V) generated by skipping exon5 of the presenilin‐2 (PS2) gene is a diagnostic feature of sporadic ...

From regulatory mechanisms to cutting‐edge applications: Research progress of ultrasound, electrical, magnetic, and optical stimulation in neural modulation

Journal of Intelligent Medicine, EarlyView.
Abstract In recent years, the clinical treatment and symptom management of neurological disorders have faced significant challenges due to the high complexity of the nervous system's structure and function. Against this backdrop, physical stimulation techniques have emerged as a vital complementary approach to traditional pharmacological treatments and

Neuroprotective effects of quercetin in animal models of neurodegenerative diseases: A systematic review and meta‐analysis

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Neurodegenerative conditions such as Alzheimer's disease and Parkinson's disease are characterized by progressive neuronal loss driven by oxidative stress and inflammation. Quercetin, a dietary flavonoid with established antioxidant and anti‐inflammatory properties, has emerged as a potential neuroprotective agent.

Depletion of microglial compensation in glial network: Disease‐associated response dynamics in the revised amyloid hypothesis

Neuroprotection, EarlyView.
The critical transition from amyloid pathology to irreversible neuronal loss in Alzheimer's disease hinges on the microglial response. This review aims to systematize the patterns of how microglia react within the glial context. Abstract Microglia mount coordinated, stage‐dependent compensatory programs in response to early amyloid β (Aβ) accumulation ...

Neuroprotective effects of ursodeoxycholic acid in Parkinson's disease and Alzheimer's disease

Neuroprotection, EarlyView.
In Parkinson's disease (PD) and Alzheimer's disease (AD), various shared pathological mechanisms exist. UDCA has been shown to exert neuroprotective effects in preclinical and clinical studies. Such effects include the mitigation of neuroinflammation as well as rescue effects on mitochondrial dysfunction, oxidative stress, impaired autophagy, and ...

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.
