Presenilin/γ-secretase and inflammation [PDF]

Frontiers in Aging Neuroscience, 2010
Presenilins (PS) are the catalytic components of gamma-secretase, an aspartyl protease that regulates through proteolytic processing the function of multiple signaling proteins. Specially relevant is the gamma-secretase-dependent cleavage of the beta-amyloid precursor protein (APP) since generates the beta-amyloid (Abeta) peptides that aggregate and ...

AKT, ATR, and Notch Inhibitors Radiosensitize a Preclinical Model of Adenoid Cystic Carcinoma

Head &Neck, EarlyView.
ABSTRACT Background Adenoid Cystic Carcinoma (ACC) is a rare and lethal type of head and neck cancer. Standard therapy involves surgery followed by radiation therapy. The majority of ACC has MYB overexpression and MYB‐NFIB gene fusions, while Notch mutations are associated with aggressive behavior.

Endogenous γ-Secretase Is Linked to Phagocytic Activity in Microglial Cells

Sensors
γ-Secretase has primarily been studied in neurons, whereas increasing evidence highlights its importance in microglia. Previous research has shown that the pharmacological inhibition of γ-secretase impairs microglial phagocytic activity.

In vitro validation of γ-secretase inhibitors alone or in combination with other anti-cancer drugs for the treatment of T-cell acute lymphoblastic leukemia

Haematologica, 2008
Background Activating NOTCH1 mutations are common in T-cell acute lymphoblastic leukemia. Inhibition of NOTCH1 signaling with γ-secretase inhibitors causes cell cycle block, but only after treatment for several days.

Nonsteroidal Anti-Inflammatory Drugs and Ectodomain Shedding of the Amyloid Precursor Protein [PDF]

, 2008
Background: Epidemiological studies have suggested that long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs) is associated with a reduced incidence of Alzheimer's disease (AD).

Somatic cell reprogramming for Parkinson's disease treatment

Ibrain, Volume 11, Issue 1, Page 59-73, Spring 2025.
The fundamental purpose of cell reprogramming to treat Parkinson's disease is to generate dopaminergic neurons (DAN) and do transplantation. There are two ways to accomplish this. One method is to induce cells into induced DA neurons (iDAN) directly or to induce cells into induced pluripotent stem cells and ultimately into iDAN in vitro. Another option

Cholesterol-Dependent γ-Secretase Activity in Buoyant Cholesterol-Rich Membrane Microdomains

Neurobiology of Disease, 2002
Buoyant membrane fractions containing presenilin 1 (PS1), an essential component of the γ-secretase complex, and APP CTFβ, a γ-secretase substrate, can be isolated from cultured cells and brain by several different fractionation procedures that are ...

γ-secretase epsilon-cleavage assay

BIO-PROTOCOL, 2017
γ-Secretase epsilon-cleavage assay is derived from the cell-based Tango assay (Kang et al., 2015), and is a fast and sensitive method to determine the initial cleavage of C99 by γ-secretase. In this protocol, we use HTL cells, which are HEK293 cells with a stably integrated luciferase reporter under the control of the bacterial tetO operator element ...

The molecular basis of T cell acute lymphoblastic leukemia [PDF]

, 2012
T cell acute lymphoblastic leukemias (T-ALLs) arise from the malignant transformation of hematopoietic progenitors primed toward T cell development, as result of a multistep oncogenic process involving constitutive activation of NOTCH signaling and ...

C/EBPβ regulates delta-secretase expression and mediates pathogenesis in mouse models of Alzheimer’s disease

Nature Communications, 2018
Delta-secretase cleaves both APP and Tau to mediate the formation of amyloid plaques and neurofibrillary tangle in Alzheimer’s disease (AD). However, how aging contributes to an increase in delta-secretase expression and AD pathologies remains unclear ...
