Vasopressin Promoter Transgenic and Vasopressin Gene-Edited Ascidian, Ciona intestinalis Type A (Ciona robusta): Innervation, Gene Expression Profiles, and Phenotypes

Frontiers in Endocrinology, 2021
Oxytocin (OT) and vasopressin (VP) superfamily neuropeptides are distributed in not only vertebrates but also diverse invertebrates. However, no VPergic innervation of invertebrates has ever been documented.

ANISEED 2017: extending the integrated ascidian database to the exploration and evolutionary comparison of genome-scale datasets

Nucleic Acids Res., 2017
ANISEED (www.aniseed.cnrs.fr) is the main model organism database for tunicates, the sister-group of vertebrates. This release gives access to annotated genomes, gene expression patterns, and anatomical descriptions for nine ascidian species. It provides

Ascidian Toxins with Potential for Drug Development

Marine Drugs, 2018
Ascidians (tunicates) are invertebrate chordates, and prolific producers of a wide variety of biologically active secondary metabolites from cyclic peptides to aromatic alkaloids.

Foxg specifies sensory neurons in the anterior neural plate border of the ascidian embryo

Nature Communications, 2019
Foxg constitutes a regulatory loop with Fgf8 and plays an important role in the development of anterior placodes and the telencephalon in vertebrate embryos.

A novel third complement component C3 gene of Ciona intestinalis expressed in the endoderm at the early developmental stages [PDF]

Invertebrate Survival Journal, 2013
The third complement component (C3) in ascidian was reported to function as an opsonin to enhance phagocytosis and as a chemotactic factor for phagocytes, indicating that ascidian C3 works in mesodermal cavity as a humoral factor like vertebrate C3s.

Transcriptional Analysis of the Endostyle Reveals Pharyngeal Organ Functions in Ascidian

Biology, 2023
The endostyle is a pharyngeal organ with an opening groove and cilia in invertebrate chordates (amphioxus and ascidian) and cyclostomate (lamprey), serving as a filter-feeding tract and thyroid-secreting location.

Biological and Chemical Diversity of Ascidian-Associated Microorganisms

Marine Drugs, 2018
Ascidians are a class of sessile filter-feeding invertebrates, that provide unique and fertile niches harboring various microorganisms, such as bacteria, actinobacteria, cyanobacteria and fungi.

Colonial Ascidian Populations at Inshore Coral Reefs of Norfolk Island, South Pacific

Diversity
Subtropical coral reefs such as the lagoonal reefs of Norfolk Island in the remote South Pacific are vastly understudied, with many benthic species unrecorded in the scientific literature.

Fertilization of Ascidians: Gamete Interaction, Self/Nonself Recognition and Sperm Penetration of Egg Coat

Frontiers in Cell and Developmental Biology, 2022
Fertilization is one of the most important events in living organisms to generate a new life with a mixed genetic background. To achieve successful fertilization, sperm and eggs must undergo complex processes in a sequential order.

Monoaminergic modulation of photoreception in ascidian: evidence for a proto-hypothalamo-retinal territory

BMC Biology, 2012
Background The retina of craniates/vertebrates has been proposed to derive from a photoreceptor prosencephalic territory in ancestral chordates, but the evolutionary origin of the different cell types making the retina is disputed.
