Expression Analysis of Heavy-Chain-Only Antibodies in Cloudy Catshark and Japanese Bullhead Shark [PDF]

Marine Drugs
Heavy chain-only antibodies in sharks are called immunoglobulin new antigen receptors (IgNAR), consisting of one variable region (VNAR) and five constant regions (C1-C5).

Gluconeogenesis in the yolk syncytial layer-like tissue of cloudy catshark (Scyliorhinus torazame) [PDF]

Physiological Reports
Glucose has important roles in the development of zebrafish, the vertebrate animal model; however, in most oviparous animals, the amount of maternally provided glucose in the yolk is scarce.

When Bigger Is Better: 3D RNA Profiling of the Developing Head in the Catshark Scyliorhinus canicula

Frontiers in Cell and Developmental Biology, 2021
We report the adaptation of RNA tomography, a technique allowing spatially resolved, genome-wide expression profiling, to a species occupying a key phylogenetic position in gnathostomes, the catshark Scyliorhinus canicula.

Testimonial of ecological and biogeographic patterns: parasite assemblages of deep water catsharks (Pentanchidae) in Icelandic waters [PDF]

Parasitology
Pentanchids (Elasmobranchii) are among the most species-rich groups of chondrichthyans. In the North Atlantic Ocean, the Icelandic catshark [Apristurus laurussonii (Saemundsson)], white ghost catshark (Apristurus aphyodes Nakaya & Stehmann), and mouse ...

The holocephalan ratfish endoskeleton shares trabecular and areolar mineralization patterns, but not tesserae, with elasmobranchs little skate and catshark [PDF]

eLife
Specific character traits of mineralized endoskeletal tissues need to be clearly defined and comprehensively examined among extant chondrichthyans (elasmobranchs, such as sharks and skates, and holocephalans, such as chimaeras) to understand their ...

Transcriptomic signature of differentiating catshark cartilage unravels the co-evolution of the Spp2 gene family with skeletal mineralisation in cartilaginous fish [PDF]

BMC Biology
Background Skeletal mineralisation, achieved through the controlled precipitation of calcium phosphate, represents a major evolutionary innovation in early vertebrates.

Hoxa9 compensates for the absence of Hoxc9 in suppressing limb-type motor neurons in sharks [PDF]

Zoological Letters
Background The transition from fins to limbs in vertebrates required a novel organization of spinal motor neurons to coordinate limb muscle activation. In amniotes, Hoxc9 represses lateral motor column (LMC) identity at thoracic levels, restricting limb ...

A single-nucleus RNA sequencing atlas of the postnatal retina of the shark Scyliorhinus canicula [PDF]

Scientific Data
The retina, whose basic cellular structure is highly conserved across vertebrates, constitutes an accessible system for studying the central nervous system.

Characterization of the tyrosine-hydroxylase immunoreactive components of the basal subpallium in sharks—toward an identification of a basal subpallial complex [PDF]

Frontiers in Neuroanatomy
Comparative studies on the forebrain across different model organisms are necessary to investigate the origin and degree of evolutionary conservation of this brain region and its derivatives. The catshark Scyliorhinus canicula has become a reliable model

Analysis of a shark reveals ancient, Wnt-dependent, habenular asymmetries in vertebrates [PDF]

Nature Communications
The mode of evolution of left-right asymmetries in the vertebrate habenulae remains largely unknown. Using a transcriptomic approach, we show that in a cartilaginous fish, the catshark Scyliorhinus canicula, habenulae exhibit marked asymmetries, in both ...
