Chitin protects the gut epithelial barrier in a protochordate model of DSS-induced colitis

Biology Open, 2018
The gastrointestinal tract of Ciona intestinalis, a solitary tunicate that siphon-filters water, shares similarities with its mammalian counterpart.

Integration of epigenetics into ecotoxicology: insights and fundamental research needs

Biological Reviews, Volume 101, Issue 2, Page 826-847, April 2026.
ABSTRACT Epigenetics refers to heritable changes in genome function that occur without direct alterations to the DNA sequence. A multitude of environmental contaminants can influence the epigenetic marks of a genome. Changes of epigenetic marks including DNA methylation, histone modifications, and non‐coding RNAs can induce alterations at the gene ...

T-type Calcium Channel Regulation of Neural Tube Closure and EphrinA/EPHA Expression

Cell Reports, 2015
A major class of human birth defects arise from aberrations during neural tube closure (NTC). We report on a NTC signaling pathway requiring T-type calcium channels (TTCCs) that is conserved between primitive chordates (Ciona) and Xenopus.

Morphological evidence that the molecularly determinedCiona intestinalistype A and type B are different species:Ciona robustaandCiona intestinalis

Journal of Zoological Systematics and Evolutionary Research, 2015
Ciona intestinalis is considered a widespread and easily recognizable tunicate, the sister group of vertebrates. In recent years, molecular studies suggested that C. intestinalis includes at least two cryptic species, named ‘type A’ and ‘type B’, morphologically indistinguishable. It is dramatic to certify that two different species may be hidden under

Where Are You From? Finding the Origin of the Recently Observed Sprat in Iceland Using a Panel of SNPs

Ecology and Evolution, Volume 16, Issue 3, March 2026.
European sprat can be divided into distinct genetic groups in the NE Atlantic, that is, Norwegian fjords, Baltic Sea and an oceanic component. The species has been increasingly reported in Icelandic waters since 2017. To investigate the source of introduction, Icelandic sprat has been genotyped and analyzed in comparison with existing reference data ...

Parallel visual circuitry in a basal chordate

eLife, 2019
A common CNS architecture is observed in all chordates, from vertebrates to basal chordates like the ascidian Ciona. Ciona stands apart among chordates in having a complete larval connectome.

Computational Analysis of Ciona intestinalis Operons [PDF]

Integrative and Comparative Biology, 2010
Operons are clusters of genes that are co-regulated from a common promoter. Operons are typically associated with prokaryotes, although a small number of eukaryotes have been shown to possess them. Among metazoans, operons have been extensively characterized in the nematode Caenorhabditis elegans in which ∼15% of the total genes are organized into ...

Genetics in the Ocean's Twilight Zone: Population Structure of the Silvery Lightfish Across Its Distribution Range

Evolutionary Applications, Volume 19, Issue 3, March 2026.
ABSTRACT The large estimates of mesopelagic fish biomass have long fuelled harvesting interests in the relatively untouched twilight zone of the ocean. The silvery lightfish—one of the most abundant species inhabiting the North Atlantic mesopelagic layer—is a candidate for such a fishery despite its enormous ecological importance and the insufficient ...

Endonuclease V: From Transcriptome Regulator to Chemical Biology Tool

ChemistryEurope, Volume 4, Issue 2, February 2026.
Post‐transcriptional modifications play a pivotal role in regulating the health and physiology of human cells, and adenosine‐to‐inosine (A‐to‐I) editing is one of the most abundant of these modifications. Inosine is read as guanosine by the cellular machinery, and this change impacts both the regulation and genetic code of RNA, in turn effectively ...

Experiments on Ciona intestinalis [PDF]

Nature, 1924
SINCE I had the pleasure of making copies, the only ones, I think, of Dr. Kammerer's photographs of Ciona during his visit to England, and believe that Prof. MacBride is not at the moment in possession of a complete set, I am taking the liberty of supplying the details requested by Mr. Cunningham in his letter to NATURE of December 15.
