Pattern Formation by Lateral Inhibition in Large-Scale Networks of Cells

TL;DR: This paper investigates the existence and stability of a “checkerboard” pattern that demonstrates the ability of neighboring cells to adopt distinct fates under lateral inhibition and exhibits a monotonicity property of the interconnected model for bipartite graphs.

Connective Tissue Growth Factor Is Required for Skeletal Development and Postnatal Skeletal Homeostasis in Male Mice

TL;DR: Connective tissue growth factor is necessary for normal skeletal development but to a lesser extent for postnatal skeletal homeostasis.

Notch signaling in response to excitotoxicity induces neurodegeneration via erroneous cell cycle reentry

TL;DR: It is shown that forcing S-phase reentry in cultured hippocampal neurons is sufficient to induce neurodegeneration and kainic-acid treatment in vivo induces erroneous CCR and neuronal death through a Notch-dependent mechanism.

Reduced Notch Signaling Leads to Renal Cysts and Papillary Microadenomas

TL;DR: It is reported that proximal tubules forming with reduced Notch signaling, resulting from delayed conditional inactivation of Notch1 and/or Notch2, are prone to cyst formation and tubular epithelial stratification, and that perturbations in notch signaling may lead to cystic renal disease and tumorigenesis.

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.
