The repertoire of G protein-coupled receptors in the sea squirt Ciona intestinalis

open access: yesBMC Evolutionary Biology, 2008
Background G protein-coupled receptors (GPCRs) constitute a large family of integral transmembrane receptor proteins that play a central role in signal transduction in eukaryotes. The genome of the protochordate Ciona intestinalis has a compact size with

The evolution and comparative neurobiology of endocannabinoid signalling [PDF]

open access: yes, 2012
CB(1)- and CB(2)-type cannabinoid receptors mediate effects of the endocannabinoids 2-arachidonoylglycerol (2-AG) and anandamide in mammals. In canonical endocannabinoid-mediated synaptic plasticity, 2-AG is generated postsynaptically by diacylglycerol ...

The Cis-Regulatory Code for Kelch-like 21/30 Specific Expression in Ciona robusta Sensory Organs

open access: yesFrontiers in Cell and Developmental Biology, 2020
The tunicate Ciona robusta is an emerging model system to study the evolution of the nervous system. Due to their small embryos and compact genomes, tunicates, like Ciona robusta, have great potential to comprehend genetic circuitry underlying cell ...

Xbp1 and Brachyury establish an evolutionarily conserved subcircuit of the notochord gene regulatory network

open access: yeseLife, 2022
Gene regulatory networks coordinate the formation of organs and structures that compose the evolving body plans of different organisms. We are using a simple chordate model, the Ciona embryo, to investigate the essential gene regulatory network that ...

How Fast Is the Sessile Ciona? [PDF]

open access: yesComparative and Functional Genomics, 2009
Genomewide analyses of distances between orthologous gene pairs from the ascidian speciesCiona intestinalisandCiona savignyiwere compared with those of vertebrates. Combining this data with a detailed and careful use of vertebrate fossil records, we estimated the time of divergence between the two ascidians nearly 180 My.

Unprecedented Diversity of ssDNA Phages from the Family Microviridae Detected within the Gut of a Protochordate Model Organism (Ciona robusta)

open access: yesViruses, 2018
Phages (viruses that infect bacteria) play important roles in the gut ecosystem through infection of bacterial hosts, yet the gut virome remains poorly characterized.

TCF/Lef regulates the Gsx ParaHox gene in central nervous system development in chordates [PDF]

open access: yes, 2016
This research was supported by a BBSRC-DTG studentship to M.G.G, and Clarendon, ORS and EPA Cephalosporin scholarships to P.W.O.Background The ParaHox genes play an integral role in the anterior-posterior (A-P) patterning of the nervous system and gut of

Prophage regulation of <i>Shewanella fidelis</i> 3313 motility and biofilm formation with implications for gut colonization dynamics in <i>Ciona robusta</i>. [PDF]

open access: yesElife
Lysogens, bacteria with one or more viruses (prophages) integrated into their genomes, are abundant in the gut of animals. Prophages often influence bacterial traits; however, the influence of prophages on the gut microbiota–host immune axis in animals ...

Bifurcations in valveless pumping techniques from a coupled fluid-structure-electrophysiology model in heart development [PDF]

open access: yes, 2017
We explore an embryonic heart model that couples electrophysiology and muscle-force generation to flow induced using a $2D$ fluid-structure interaction framework based on the immersed boundary method.
