The FEBS Journal, Volume 293, Issue 8, Page 2248-2269, April 2026.Zebrafish Tgds, when expressed as a recombinant protein, catalyzes the dehydration of UDP‐D‐glucose, the initial step in the formation of 6‐deoxyhexoses. Corresponding Tgds mutations found in Catel–Manzke syndrome patients lead to reduced enzymatic activity and stability.

Growth and energetics in the ascidian Ciona intestinalis [PDF]
Marine Ecology Progress Series, 1995 Rates of growth, filtration and respiration of the ascidian Ciona intestinalis (L.) were measured in the laboratory in the presence of food (flagellate Rhodomonas sp.) concentrations ranging from 0 to 12000 cells ml-' (0 to 500 pg C I-'). Weight-specific growth rate (dry weight of body parts not including the tunic) increased sigrnoidally with ...

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 ...

Effects of tributyltin chloride in ascidian embryos: modulation of kinase-mediated signalling pathways [PDF]
Invertebrate Survival Journal, 2009 We studied the effects of various TBT concentrations by assaying the activity of ERK 1/2 (p44/42) and phospho-ERK1/2 (phospho-p44/42), proteins with a key role in ascidian development, and tyrosine kinase-dependent pathway. The effects of this xenobiotic

Tributyltin affects phagocytic activity of Ciona intestinalis hemocytes [PDF]
Comparative Biochemistry and Physiology Part C: Pharmacology, Toxicology and Endocrinology, 1995 Organotin compounds have been used in marine anti-fouling paints as biocides. Because tunicates are vulnerable to these compounds in their natural habitats, we used Ciona intestinalis to establish an assay for phagocytosis in vitro of yeast by hemocytes after exposure to different concentrations (0.0015, 0.015, 0.15 and 1.5 microM) of four organotin ...

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 ...

Asymmetric divergence in structure and function of HCN channel duplicates in Ciona intestinalis. [PDF]
PLoS ONE, 2012 Hyperpolarization-activated Cyclic Nucleotide (HCN) channels are voltage-gated cation channels and are critical for regulation of membrane potential in electrically active cells.

Structure and behaviour of the sperm terminal filament [PDF]
, 1982 Light- and electron-microscopic observations of Ciona and Lytechinus spermatozoa show a thin terminal filament at the distal end. The terminal filament is 5-6 microns long and contains the two central microtubules and a variable number of A-tubule ...

Evolution of Ciona intestinalis Tumor necrosis factor alpha (CiTNFα): Polymorphism, tissues expression, and 3D modeling [PDF]
, 2017 Although the Tumor necrosis factor gene superfamily seems to be very conserved in vertebrates, phylogeny, tissue expression, genomic and gene organization, protein domains and polymorphism analyses showed that a strong change has happened mostly in ...
