Transcriptomic validation of a 7,12 Dimethylbenz(a)anthracene (DMBA)‐induced leukemia rat model: Parallels with human leukemogenesis

open access: yesAnimal Models and Experimental Medicine, EarlyView.
7,12‐Dimethylbenz[a]anthracene (DMBA) could induce leukemia and other types of cancers in rat models. Transcriptomics revealed gene expression profile that parallels with human leukemia. DMBA‐induced differential gene expression could validate the developed rat model.

Cellular basis of Alzheimer′s disease

open access: yesAnnals of Indian Academy of Neurology, 2010
Alzheimer′s disease (AD) is the most common form of neurodegenerative disease. A characteristic feature of the disease is the presence of amyloid-β (Aβ) which either in its soluble oligomeric form or in the plaque-associated form is ...

Secretase promotes AD progression: simultaneously cleave Notch and APP

open access: yesFrontiers in Aging Neuroscience
Alzheimer’s disease (AD) involves complex pathological mechanisms. Secretases include membrane protein extracellular structural domain proteases and intramembrane proteases that cleave the topology to type I or type II.

Phosphorylation of amyloid precursor carboxy-terminal fragments enhances their processing by a gamma-secretase-dependent mechanism

open access: yesNeurobiology of Disease, 2005
In Alzheimer's disease, the complex catabolism of amyloid precursor protein (APP) leads to the production of amyloid-beta (Abeta) peptide, the major component of amyloid deposits.

Caveolin‐1 inhibition mediates the opposing effects of alcohol on γ‐secretase activity in arterial endothelial and smooth muscle cells

open access: yesPhysiological Reports, 2023
Notch is important to vessel homeostasis. We investigated the mechanistic role of caveolin‐1 (Cav‐1) in mediating the effects of alcohol (Ethanol/EtOH) on the γ‐secretase proteolytic activity necessary for Notch signaling in vascular cells.

Region-specific dendritic simplification induced by Aβ, mediated by tau via dysregulation of microtubule dynamics: a mechanistic distinct event from other neurodegenerative processes. [PDF]

open access: yes, 2015
BackgroundDendritic simplification, a key feature of the neurodegenerative triad of Alzheimer's disease (AD) in addition to spine changes and neuron loss, occurs in a region-specific manner.

BACE2, a conditional β-secretase, contributes to Alzheimer's disease pathogenesis.

open access: yesJCI Insight, 2019
Deposition of amyloid-β protein (Aβ) to form neuritic plaques is the characteristic neuropathology of Alzheimer's disease (AD). Aβ is generated from amyloid precursor protein (APP) by β- and γ-secretase cleavages.

Intravenous Lipopolysaccharide Challenge in Healthy Participants Reveals Pharmacodynamic Markers in Blood and Bone Marrow for Early‐Phase Oncology Drug Development

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Demonstrating pharmacological effects in early‐phase oncology clinical trials remains challenging, largely due to the lack of robust pharmacodynamic markers. Lipopolysaccharide (LPS) is used as an immune challenge agent in healthy participants to study drugs for autoimmune conditions.

Emerging structures and dynamic mechanisms of γ-secretase for Alzheimer’s disease

open access: yesNeural Regeneration Research
γ-Secretase, called “the proteasome of the membrane,” is a membrane-embedded protease complex that cleaves 150+ peptide substrates with central roles in biology and medicine, including amyloid precursor protein and the Notch family of cell-surface ...

The resveratrol trimer miyabenol C inhibits β-secretase activity and β-amyloid generation.

open access: yesPLoS ONE, 2015
Accumulation and deposition of amyloid-β peptide (Aβ) in the brain is a primary cause of the pathogenesis of Alzheimer's disease (AD). Aβ is generated from amyloid-β precursor protein (APP) through sequential cleavages first by β-secretase and then by γ ...
