Presenilin 1 is essential for cardiac morphogenesis [PDF]
AbstractPresenilin 1 (PS1) is the gene responsible for the development of early‐onset familial Alzheimer's disease. PS1‐deficient mice have been reported to show defects in neurogenesis, somitogenesis and angiogenesis. Here, we report cardiac anomaly in PS1‐deficient mice: the mutant hearts exhibited ventricular septal defect, double outlet right ...

Fatty acids increase presenilin-1 levels and γ-secretase activity in PSwt-1 cells
Presenilin-1 (PS1) is an important determinant of the γ-secretase activity necessary for the generation of β-amyloid (Aβ), likely the central pathogenic molecule in Alzheimer's disease.

Cholestenoic acid, an endogenous cholesterol metabolite, is a potent γ-secretase modulator. [PDF]
BackgroundAmyloid-β (Aβ) 42 has been implicated as the initiating molecule in the pathogenesis of Alzheimer's disease (AD); thus, therapeutic strategies that target Aβ42 are of great interest.

Presenilin-1 Dependent Neurogenesis Regulates Hippocampal Learning and Memory. [PDF]
Presenilin-1 (PS1), the catalytic core of the aspartyl protease γ-secretase, regulates adult neurogenesis. However, it is not clear whether the role of neurogenesis in hippocampal learning and memory is PS1-dependent, or whether PS1 loss of function in ...

It has been a quarter century since the discovery that molecular motors are phosphorylated, but fundamental questions still remain as to how specific kinases contribute to particular motor functions, particularly in vivo, and to what extent these ...

Presenilin-1 and Memories of the Forebrain [PDF]
In this issue of Neuron, report that forebrain-specific Presenilin-1 conditional knockout mice show defects in enrichment-induced neurogenesis in the dentate gyrus. This defect in neurogenesis is associated with enhanced fear memory of contextual cues when animals are subjected to enrichment between training and testing.

The Nicastrin ectodomain adopts a highly thermostable structure [PDF]
Nicastrin is a type I transmembrane glycoprotein, which is part of the high molecular weight gamma-secretase complex. gamma-Secretase is one of the key players associated with the generation of Alzheimer's disease pathology, since it liberates the ...

miRNA-based rapid differentiation of purified neurons from hPSCs advancestowards quick screening for neuronal disease phenotypes in vitro [PDF]
Obtaining differentiated cells with high physiological functions by an efficient, but simple and rapid differentiation method is crucial for modeling neuronal diseases in vitro using human pluripotent stem cells (hPSCs).

Presenilins Upregulate Functional K+Channel Currents in Mammalian Cells
Mutations in presenilin 1 (PS-1) and presenilin 2 (PS-2) have been linked to early onset, autosomal dominant Alzheimer's disease. Neither the normal function(s) of the presenilins nor their role(s) in mediating the devastating neurological and ...
