SpBase: the sea urchin genome database and web site [PDF]

open access: yes, 2008
SpBase is a system of databases focused on the genomic information from sea urchins and related echinoderms. It is exposed to the public through a web site served with open source software (http://spbase.org/). The enterprise was undertaken to provide an

Gastrulation in the sea urchin

open access: yes, 2020
Gastrulation is arguably the most important evolutionary innovation in the animal kingdom. This process provides the basic embryonic architecture, an inner layer separated from an outer layer, from which all animal forms arise. An extraordinarily simple and elegant process of gastrulation is observed in the sea urchin embryo. The cells participating in

Eutacticity in Sea Urchin Evolution [PDF]

open access: yesBulletin of Mathematical Biology, 2007
An eutactic star, in a n-dimensional space, is a set of N vectors which can be viewed as the projection of N orthogonal vectors in a N-dimensional space. By adequately associating a star of vectors to a particular sea urchin we propose that a measure of the eutacticity of the star constitutes a measure of the regularity of the sea urchin. Then we study

Sequencing and analysis of the gastrula transcriptome of the brittle star Ophiocoma wendtii [PDF]

open access: yes, 2012
Background The gastrula stage represents the point in development at which the three primary germ layers diverge. At this point the gene regulatory networks that specify the germ layers are established and the genes that define the differentiated states ...

Bioerosive impact of Diadema mexicanum on southern Mexican Pacific coral reefs

open access: yesCiencias Marinas, 2016
Reef ecosystem growth and maintenance is closely related to sea urchin feeding activities. Hence, quantifying the bioerosive capacity of the sea urchin Diadema mexicanum is necessary to evaluate its impact on coral communities and reefs that develop off

Sea urchin utilisation in Eastern Indonesia

open access: yesIlmu Kelautan, 2023
Sea urchins have long been an important component of gleaning invertebrate fisheries and are valued for their highly nutritious gonads. Sea urchin fisheries are often unreported and unregulated, despite increasing indications of overexploitation. Data on

Dypeptydylpeptidase IV Activity Ingibition after Oral Administration to Rabbits of Strongylocentrotus Droebahiensis Gonads Extract as Possible Biomarker of Pharmakokinetics

open access: yesРазработка и регистрация лекарственных средств, 2020
Introduction. The pharmacokinetic profiling of active compounds is necessary for drug development and application. Comlex extract of biologically active compounds was isolated from gonads of green sea urchin Strongylocentrotus droebachiensis from Barents
