Notch Signaling: Cell Fate Control and Signal Integration in Development
TLDR
Notch signaling defines an evolutionarily ancient cell interaction mechanism, which plays a fundamental role in metazoan development, providing a general developmental tool to influence organ formation and morphogenesis.Abstract:
Notch signaling defines an evolutionarily ancient cell interaction mechanism, which plays a fundamental role in metazoan development. Signals exchanged between neighboring cells through the Notch receptor can amplify and consolidate molecular differences, which eventually dictate cell fates. Thus, Notch signals control how cells respond to intrinsic or extrinsic developmental cues that are necessary to unfold specific developmental programs. Notch activity affects the implementation of differentiation, proliferation, and apoptotic programs, providing a general developmental tool to influence organ formation and morphogenesis.read more

Dynamic compaction of human mesenchymal stem/precursor cells into spheres self-activates caspase-dependent IL1 signaling to enhance secretion of modulators of inflammation and immunity (PGE2, TSG6, and STC1)
TL;DR: It is demonstrated that MSC spontaneously aggregated into sphere‐like structures after injection into a subcutaneous air pouch or the peritoneum of mice, indicating that assembly of MSC into spheres triggers caspase‐dependent IL1 signaling and the secretion of modulators of inflammation and immunity.
Making a tooth： growth factorsξ┐ transcription factorsξ┐ and stem cells
TL;DR: Recent progress in the studies of molecular basis of tooth development, adult stem cell biology, and regeneration will provide fundamental knowledge for the realization of human tooth regeneration in the near future.

Expression of Notch pathway components in fetal and adult mouse small intestine.
Natalia Schröder,Achim Gossler +1 more
TL;DR: In this article, the expression of the genes encoding the murine Notch receptors (Notch1-4), the ligands (delta1, 3, 4 and Jagged1, 2), the modifying glycosyltransferases of the fringe family (Lfng, Mfng and Rfng), and four Hes genes (Hes1, 5, 6, 7) in the mouse small intestine during fetal (E13.5 and E18.5) and postnatal (P25) development.

Delayed, asynchronous, and reversible T-lineage specification induced by Notch/Delta signaling
TL;DR: While necessary to induce and sustain T-cell development, Notch/Delta signaling is not sufficient for T-lineage specification and commitment, but instead can be permissive for the maintenance and proliferation of uncommitted progenitors that are omitted in binary-choice models.
Journal ArticleDOI
Notch activity permits retinal cells to progress through multiple progenitor states and acquire a stem cell property.
TL;DR: The data suggest that prolonged Notch activity does not disrupt the normal progression of progenitor temporal states, and that down-regulating or overcoming NotCh activity is required for proper formation of both neuronal and glial cell fates.

TL;DR: The characterization of the human Notch3 gene, which was previously mapped to the CADASIL critical region, is reported, indicating that Notch 3 could be the defective protein in CADASil patients.

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.

Signalling downstream of activated mammalian Notch.
Sophie Jarriault,Christel Brou,Frédérique Logeat,Eric H. Schroeter,Raphael Kopan,Alain Israël +5 more
TL;DR: It is shown that activated forms of mNotch associate with the human analogue of Su(H), KBF2/RBP-JK and act as transcriptional activators through theKBF2-binding sites of the HES-1 promoter and block MyoD-induced myogenesis5-7.

Notch signaling : Signal transduction
TL;DR: The Notch/Lin-12/Glp-1 receptor family mediates the specification of numerous cell fates during development in Drosophila and Caenorhabditis elegans and putative components of the signaling cascade are identified, including a conserved family of extracellular ligands and two cellular factors that may associate with the Notch Intracellular domain.

TL;DR: Four distinct coding mutations in JAG1 are demonstrated, providing evidence that it is the causal gene for Alagille syndrome, and supporting the hypothesis that haploinsufficiency for this gene is one of the mechanisms causing the Alagile syndrome phenotype.
