Is the amyloid hypothesis of Alzheimer's disease therapeutically relevant?

TL;DR: It is argued in the present review that a more direct (and possibly simpler) approach to AD therapeutics is to rescue synaptic dysfunction directly, by focusing on the mechanisms by which elevated levels of β-amyloid disrupt synaptic physiology.
Journal ArticleDOI

Notch signaling: genetics and structure.

TL;DR: The genetics of Notch in C. elegans is covered, focusing on conserved core components and modulators, and structural information about these components is included, describing the key events occurring during ligand binding and transcriptional control of target genes.
Journal ArticleDOI

Osteoporosis and Bone Mass Disorders: From Gene Pathways to Treatments

TL;DR: Overlap exists between the genes implicated in monogenic and complex forms of bone mass disorders, largely explained by the clustering of genes encoding factors in signaling pathways crucial for mesenchymal cell differentiation, skeletal development and bone remodeling and metabolism.

Wnt and Notch Signals Guide Embryonic Stem Cell Differentiation into the Intestinal Lineages

TL;DR: In vitro differentiation procedure of pluripotent stem cells into definitive endoderm (DE), inductive signal pathways' guiding differentiation into intestinal cells was investigated and concluded that Wnt and Notch signaling function to pattern the anterior‐posterior axis of the DE and control intestinal differentiation.

Control of hair follicle cell fate by underlying mesenchyme through a CSL–Wnt5a–FoxN1 regulatory axis

TL;DR: It is reported that maintenance of the hair follicle keratinocyte cell fate is defective in mice with mesenchymal deletion of the CSL/RBP-Jkappa gene, the effector of "canonical" Notch signaling.

Notch signalling: a simple pathway becomes complex

TL;DR: Although the intracellular transduction of the Notch signal is remarkably simple, with no secondary messengers, this pathway functions in an enormous diversity of developmental processes and its dysfunction is implicated in many cancers.
Journal ArticleDOI

Notch-1 signalling requires ligand-induced proteolytic release of intracellular domain.

TL;DR: It is shown that signalling by a constitutively active membrane-bound Notch-1 protein requires the proteolytic release of the Notch intracellular domain (NICD), which interacts preferentially with CSL.

Notch/gamma-secretase inhibition turns proliferative cells in intestinal crypts and adenomas into goblet cells.

TL;DR: This work shows a rapid, massive conversion of proliferative crypt cells into post-mitotic goblet cells after conditional removal of the common Notch pathway transcription factor CSL/RBP-J and indicates that γ-secretase inhibitors, developed for Alzheimer's disease, might be of therapeutic benefit in colorectal neoplastic disease.
