Endothelin-1 regulates the dorsoventral branchial arch patterning in mice

Endothelin-1 (ET-1), a 21-amino acid peptide secreted by the epithelium and core mesenchyme in the branchial arches as well as vascular endothelium, is involved in craniofacial and cardiovascular development through endothelin receptor type-A (EdnrA) expressed in the neural crest-derived ectomesenchyme. Here we show that ET-1(-/-) mutant mice exhibit a homeotic-like transformation of the lower ...

Temporal requirement of signaling cascade involving endothelin-1/endothelin receptor type A in branchial arch development

Intercellular interactions within the branchial arch (BA) system is essential for craniofacial development. Endothelin-1 (ET-1), produced by the branchial epithelium and core mesenchyme, acts on cranial neural crest-derived ectomesenchymcal cells expressing endothelin A receptor (ETAR) and regulates expression of crucial genes such as Dlx6, a member of distalless homeobox gene family, and its d...

Gremlin 2 regulates distinct roles of BMP and Endothelin 1 signaling in dorsoventral patterning of the facial skeleton.

Patterning of the upper versus lower face involves generating distinct pre-skeletal identities along the dorsoventral (DV) axes of the pharyngeal arches. Whereas previous studies have shown roles for BMPs, Endothelin 1 (Edn1) and Jagged1b-Notch2 in DV patterning of the facial skeleton, how these pathways are integrated to generate different skeletal fates has remained unclear. Here, we show tha...

A signaling cascade involving endothelin-1, dHAND and msx1 regulates development of neural-crest-derived branchial arch mesenchyme.

Numerous human syndromes are the result of abnormal cranial neural crest development. One group of such defects, referred to as CATCH-22 (cardiac defects, abnormal facies, thymic hypoplasia, cleft palate, hypocalcemia, associated with chromosome 22 microdeletion) syndrome, exhibit craniofacial and cardiac defects resulting from abnormal development of the third and fourth neural crest-derived b...

The second branchial arch: rheumatological manifestations.

In the course of normal development in man, the middle and largest part of the second branchial arch, the keratohyal cartilage, develops into a fibrous cord, the so-called stylohyoid ligament. Ossification takes place solely at its two ends, that is, in the hyoid bone and in the styloid process of the skull. In the present paper the significance for the clinical rheumatologist of some developme...
