Fifteen human healthy volunteers, divided into three groups, received a single dose of placebo or either 140 mg or 280 mg of the ?-secretase inhibitor semagacestat (LY450139). Endogenous peptides in CSF, sampled prior to administration of the drug and at six subsequent time points, were analyzed by ...

γ-secretase is an intra-membrane-cleaving aspartyl protease implicated in the processing of a wide range of type I membrane proteins including the Notch receptor and the amyloid-β precursor protein (APP). It thus regulates a diverse array of cellular and biological processes including the differen...

Glioblastomas (GBM) are poorly differentiated astrocytic tumors arising in the Central Nervous System (CNS), which despite aggressive treatments are still characterized by a fatal outcome. Several studies have shown the existence of a subpopulation of cells within glioma tumors displaying cancer ste...

Glucocorticoids are an essential component of the treatment of lymphoid malignancies and resistance to glucocorticoid therapy constitutes a prominent clinical problem in relapsed and refractory lymphoblastic leukemias. Constitutively active NOTCH signaling is involved in the pathogenesis of over 50%...

We used DNA microarrays to compare RNA transcript expression from various glioma neurospheres after treatment with gamma-secretase inhibitor MRK003. Four glioma cell lines grown as neurospheres (GBM1, GBM2, GBM10 and GBM14) were treated two concentrations of with gamma-secretase inhibitor MRK003 (Hi...

The adhesion molecule CD99 is essential for transendothelial migration (TEM) of leukocytes. Here we demonstrate by biochemical and cellular assays that CD99 undergoes ectodomain shedding by the metalloprotease meprin ? and subsequent intramembrane proteolysis by ?-secretase. The cleavage site in CD9...

γ-Secretase is a transmembrane protease complex responsible for processing multiple type I transmembrane proteins, including the amyloid precursor protein (APP) and NOTCH. Using a proteomics-based screening approach, we found that dedicator of cytokinesis protein 2 (DOCK2) interacts with the γ-secre...

Lineage-negative thymocytes were cultured on OP9-DL1 stromal cells for 16h in the presence of DMSO or the gamma secretase inhibitor MRK-003. DN3 cells cells were then sorted and their transcriptome analyzed. 8 samples
