Endothelins (EDN1, EDN2, EDN3) and Their Receptors (EDNRA, EDNRB, EDNRB2) in Chickens: Functional Analysis and Tissue Distribution.

Endothelins (EDN1, EDN2, EDN3) and Their Receptors (EDNRA, EDNRB, EDNRB2) in Chickens: Functional Analysis and Tissue Distribution. Gen Comp Endocrinol. 2019 Jul 24;:113231 Authors: Liu H, Luo Q, Zhang J, Mo C, Wang Y, Li J Abstract Endothelins (EDNs) and their receptors (EDNRs) are reported to be involved in the regulation of many physiological/pathological processes, such as cardiovascular development and functions, pulmonary hypertension, neural crest cell proliferation, differentiation and migration, pigmentation, and plumage in chickens. However, the functionality, signaling, and tissue expression of avian EDN-EDNRs have not been fully characterized, thus impeding our comprehensive understanding of their roles in this model vertebrate species. Here, we reported the cDNAs of three EDN genes (EDN1, EDN2, EDN3) and examined the functionality and expression of the three EDNs and their receptors (EDNRA, ENNRB and EDNRB2) in chickens. The results showed that: 1) chicken (c-) EDN1, EDN2, and EDN3 cDNAs were predicted to encode bioactive EDN peptides of 21 amino acids, which show remarkable degree of amino acid sequence identities (91-95%) to their respective mammalian orthologs; 2) chicken (c-) EDNRA expressed in HEK293 cells could be preferentially activated by chicken EDN1 and EDN2 , monitored by the three established cell-based luciferase reporter assays, indicating that cEDNRA is a functional receptor common for both cEDN1 and cEDN...
