Association of active γ-secretase complex with lipid rafts

open access: yesJournal of Lipid Research, 2005
Cholesterol has been implicated in the pathogenesis of Alzheimer's disease (AD). Although the underlying mechanisms are not yet clear, several studies have provided evidence for the involvement of cholesterol-rich lipid rafts in the production of amyloid

Maml1 acts cooperatively with Gli proteins to regulate Sonic hedgheog signaling pathway [PDF]

open access: yes, 2017
Sonic hedgehog (Shh) signaling is essential for proliferation of cerebellar granule cell progenitors (GCPs) and its misregulation is linked to various disorders, including cerebellar cancer medulloblastoma.

EN2 Regulates Pancreatic Cancer Initiation, Progression, and Epithelial‐Mesenchymal Transition Through the Notch Signalling Pathway

open access: yesJournal of Cellular and Molecular Medicine, Volume 30, Issue 9, May 2026.
ABSTRACT The incidence and mortality of pancreatic cancer are steadily increasing worldwide, and the disease is projected to become the second leading cause of cancer‐related deaths by 2030. Pancreatic tumorigenesis is driven by multiple genetic alterations, underscoring the need to elucidate the molecular mechanisms underlying pancreatic ...

Effects of hypertension and anti-hypertensive treatment on Aβ plaque load, Aβ–synthesising and –degrading enzymes in frontal cortex [PDF]

open access: yes, 2016
Epidemiological data associate hypertension with a predisposition to Alzheimer’s disease (AD), and a number of postmortem and in vivo studies also demonstrate that hypertension increases amyloid-β (Aβ) pathology.

Psychobiotics and the microbiota–gut–brain axis: Emerging paradigms in mental health modulation

open access: yesExperimental Physiology, Volume 111, Issue 5, Page 2449-2463, 1 May 2026.
Abstract The global rise in mental health conditions has prompted interest in interventions that act beyond conventional psychopharmacology. Psychobiotics, broadly understood as live microorganisms or microbe‐derived products that interact with the microbiota–gut–brain axis, have been suggested to exert neuroactive effects through neural, immune ...

Plasmalogens Inhibit APP Processing by Directly Affecting γ-Secretase Activity in Alzheimer’s Disease

open access: yesThe Scientific World Journal, 2012
Lipids play an important role as risk or protective factors in Alzheimer’s disease (AD). Previously it has been shown that plasmalogens, the major brain phospholipids, are altered in AD.

ABCG1 and ABCG4 Suppress γ-Secretase Activity and Amyloid β Production.

open access: yesPLoS ONE, 2016
ATP-binding cassette G1 (ABCG1) and ABCG4, expressed in neurons and glia in the central nervous system, mediate cholesterol efflux to lipid acceptors. The relationship between cholesterol level in the central nervous system and Alzheimer's disease has ...

A novel Aβ isoform pattern in CSF reflects γ-secretase inhibition in Alzheimer disease [PDF]

open access: yes, 2010
: INTRODUCTION: LY450139 (semagacestat) inhibits gamma-secretase, a key enzyme for generation of amyloid beta (Abeta), the peptide deposited in plaques in Alzheimer disease (AD).

Residues at P2-P1 positions of ɛ- and ζ-cleavage sites are important in formation of β-amyloid peptide

open access: yesNeurobiology of Disease, 2009
Most of the Alzheimer's disease (AD)-linked mutations in amyloid precursor protein (APP), which cause abnormal production of β-amyloid (Aβ), are localized at the major β-secretase-and γ-secretase cleavage sites. In this study, using an APP-knockout mouse
