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

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

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

Diet and Plastic Ingestion in the Blackmouth Catshark Galeus melastomus, Rafinesque 1810, in Italian Waters [PDF]
Animals, 2023 Galeus melastomus is the most common Pentanchidae in the Mediterranean Sea. A scavenger and opportunistic feeder, and despite the wide distribution, little is known about its feeding habits in Italian waters.

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

Interference with the retinoic acid signalling pathway inhibits the initiation of teeth and caudal primary scales in the small-spotted catshark Scyliorhinus canicula [PDF]
PeerJ, 2023 The retinoic acid (RA) pathway was shown to be important for tooth development in mammals, and suspected to play a key role in tooth evolution in teleosts.
