.... Echinoderm Glycine receptor nAChR GABA receptor Dopamine receptor Adrenergic receptor Strongylocentrotus purpuratus University of the South University of the South Echinoderms, particularly sea urchins, are an important model organism in developmental biology ( Adonin...

... ). A recent study on the purple sea urchin Strongylocentrotus purpuratus showed the lack of challenging environmental conditions associated with quiescent laboratory conditions (gentle water movement and constant immersion) resulted in the reduction of tube foot disc size and adhesive capability ( Narvaez...

... in the process and could thus undergo repeated cycles of efflux and re-entry. Here we use embryos of the purple sea urchin, Strongylocentrotus purpuratus , as a model to determine transport costs and benefits under environmentally relevant xenobiotic concentrations. Strikingly, our results show that efflux...

... gastrulation and the initiation of spiculogenesis, two crucial developmental processes in the purple sea urchin, Strongylocentrotus purpuratus . Embryos were reared at the current, accepted oceanic CO 2 concentration of 380 microatmospheres (μatm), and at the elevated levels of 1000 and 1350 μatm, simulating...

... urchin Strongylocentrotus purpuratus that encodes two copies of an NGIWYamide-like peptide:Asn-Gly-Phe-Phe-Phe-(NH 2 ) or NGFFFamide. Interestingly, the C-terminal region of the NGFFFamide precursor shares sequence similarity with neurophysins, carrier proteins hitherto uniquely associated...

.... An alternative strategy for identification of echinoid SALMFamides was provided by sequencing the genome of the sea urchin Strongylocentrotus purpuratus . Analysis of whole-genome shotgun sequence data using the Basic Local Alignment Search Tool (BLAST) identified a contig (347664) that contains a coding region...

...Lori A. Clow; David A. Raftos; Paul S. Gross; L. Courtney Smith SUMMARY The purple sea urchin Strongylocentrotus purpuratus expresses a homologue of complement component C3 (SpC3), which acts as a humoral opsonin. Significantly increased phagocytic activity was evident when yeast target cells were...
