Evolutionary Adaptation of the Thyroid Hormone Signaling Toolkit in Chordates
Cells, 2021 The specification of the endostyle in non-vertebrate chordates and of the thyroid gland in vertebrates are fundamental steps in the evolution of the thyroid hormone (TH) signaling to coordinate development and body physiology in response to a range of ...

Pax258 and Pax6 alternative splicing events in basal chordates and vertebrates: a focus on paired box domain [PDF]
Frontiers in Genetics, 2015 Paired box transcription factors play important role in development and tissue morphogenesis. The number of Pax homologs varies among species studied so far, due to genome and gene duplications that have affected PAX family to a great extent.

A conserved non-reproductive GnRH system in chordates.
PLoS ONE, 2012 Gonadotropin-releasing hormone (GnRH) is a neuroendocrine peptide that plays a central role in the vertebrate hypothalamo-pituitary axis. The roles of GnRH in the control of vertebrate reproductive functions have been established, while its non ...

Retinoic acid signaling and the evolution of chordates
International Journal of Biological Sciences, 2006 In chordates, which comprise urochordates, cephalochordates and vertebrates, the vitamin A-derived morphogen retinoic acid (RA) has a pivotal role during development.

Evidence for gill slits and a pharynx in Cambrian vetulicolians: implications for the early evolution of deuterostomes [PDF]
, 2012 Background Vetulicolians are a group of Cambrian metazoans whose distinctive bodyplan continues to present a major phylogenetic challenge. Thus, we see vetulicolians assigned to groups as disparate as deuterostomes and ecdysozoans.

Evolution of the role of RA and FGF signals in the control of somitogenesis in chordates [PDF]
, 2015 The laboratory of HE is supported by the ANR BLAN 1716 01. IMLS´s laboratory is currently supported by MASTS (Marine Alliance for Science and Technology Scotland).During vertebrate development, the paraxial mesoderm becomes segmented, forming somites ...

Hemichordates and the origin of chordates [PDF]
Current Opinion in Genetics & Development, 2005 Hemichordates, the phylum of bilateral animals most closely related to chordates, could reveal the evolutionary origins of chordate traits such as the nerve cord, notochord, gill slits and tail. The anteroposterior maps of gene expression domains for 38 genes of chordate neural patterning are highly similar for hemichordates and chordates, even though ...
