Introduction

Notch structure cartoon^[1]

The nodal proteins were first identified in drosophila development and have since been identified as regulators of cell fate decisions during development. These are a family of cell surface transmembrane receptors that pass once through the plasma membrane.

Some Recent Findings

More recent papers
This table allows an automated computer search of the external PubMed database using the listed "Search term" text link. This search now requires a manual link as the original PubMed extension has been disabled. The displayed list of references do not reflect any editorial selection of material based on content or relevance. References also appear on this list based upon the date of the actual page viewing. References listed on the rest of the content page and the associated discussion page (listed under the publication year sub-headings) do include some editorial selection based upon both relevance and availability.

Older papers
These papers originally appeared in the Some Recent Findings table, but as that list grew in length have now been shuffled down to this collapsible table. See also the Discussion Page for other references listed by year and References on this current page.

Nodal Signaling

Nodal Receptors

Nodal Ligands

Functions

Developmental patterning signal.

Endoderm Development

Endoderm differentiates to form the respiratory airway epithelium and glands. This epithelium is continuously replaced through life from a basal cell pool of undifferentiated airway progenitors. A recent study^[3] has shown that the progenitor pool is regulated by the Notch3-Jagged signaling pathway. The mechanism appears dependent upon the availability of Jag1 and Jag2 (generating parabasal cells) that later activates Notch1 and Notch2 leading to a secretory-multiciliated cell fate.

-* Caudal to rostral decreasing FGF gradient, leads to Delta-1 expression decrease in cells that leave the stem zone (light blue) and move into the PNTZ where they intermingle with cells that do not express Delta-1.
-* Generates differences in DELTA/NOTCH signalling between adjacent cells that may initiate lateral inhibition.
-* Upregulation of Delta-1 in single NP cells which signal (blue arrows) and activate NOTCH signalling in adjacent cells, which as a consequence express Hes5 and are maintained in a proliferating state.
-* Delta-1 expressing NP cell divides into two cells that express Tis21.
-* Double Delta-1/Tis21 labelled NP down regulate the expression of Delta-1 as they reach the NZ and begin to divide in a neurogenic manner.
-* One of the daughter cells upregulates Delta-1 expression and differentiates as a neuron while the other one, which receives NOTCH signalling (blue arrows), remains as neurogenic NP.

 ==Abnormalities==
-===Alagille Syndrome===
-Mutations in the human homolog of Jagged-1 (JAG1) located on chromosome 20p12 cause [[Alagille Syndrome]]. Abnormalities are seen in gastrointestinal (liver cholestasis), cardiac (heart), renal (kidney), skeletal, ocular, and facial systems.
