High impact information on Echinodermata

• S1 and S2 are the first neuropeptides identified in species belonging to the phylum Echinodermata [1].
• Synergic effects of tryptamine and octopamine on ophiuroid luminescence (Echinodermata) [2].
• This study tests the hypotheses that the birefringent calcite and stereom structure of the brittlestar (Ophiuroidea, Echinodermata) endoskeleton polarizes light and that certain brittlestars respond to polarized light [3].
• Cells in the intestinal system of holothurians (Echinodermata) express cholecystokinin-like immunoreactivity [4].
• Inhibition of arm regeneration by Ophioderma brevispina (Echinodermata, Ophiuroidea) by tributyltin oxide and triphenyltin oxide [5].

Anatomical context of Echinodermata

• Progesterone metabolism in the ovaries and testes of the echinoid Lytechinus variegatus Lamarck (Echinodermata) [6].

Associations of Echinodermata with chemical compounds

• Sexual difference in latent period of spawning following injection of the hormone 1-methyladenine in Echinaster (Echinodermata: Asteroidea) [7].
• Short-term stress relaxation tests were conducted on sections of holothurian (Echinodermata) body wall immersed in isotonic monovalent and divalent salt solutions and deionized water [8].
• Tauropine dehydrogenase from the starfish Asterina pectinifera (Echinodermata: Asteroidea): presence of opine production pathway in a deuterostome invertebrate [9].

Gene context of Echinodermata

• Acrosin is widely distributed from Insecta to Echinodermata and Vertebrata; hyaluronidase has a similar diffusion, but seems to be absent from an Insect and from Echinodermata [10].
