MetabolomicsUnique metabolic regulation of micromeres contributes to their inductive signaling in the sea urchin embryo

In many multicellular organisms, a group of cells called organizers plays critical roles by sending signals to adjacent cells and controlling patterning events such as embryogenesis and tissue morphogenesis. Recent studies suggest that these organizers or inductive cells facilitate the downstream...

TranscriptomicsGenetics of gene expression responses to temperature stress in a sea urchin gene network (DASL)
Stress responses play an important role in shaping species distributions and robustness to climate change. We investigated how stress responses alter the contribution of additive genetic variation to gene expression during development of the purple sea urchin, Strongylocentrotus purpuratus, under in...

TranscriptomicsSelect microRNAs are essential for early development in the sea urchin.
microRNAs (miRNAs) are small noncoding RNAs that mediate post-transcriptional gene regulation and have emerged as essential regulators of many developmental events. The transcriptional network during early embryogenesis of the purple sea urchin, Strongylocentrotus purpuratus, is well described and w...

TranscriptomicsPurple sea urchin larvae alter their transcriptome in response to ocean acidification
In this research we present a transcriptomics analysis of the physiological response of a marine calcifier, Strongylocentrotus purpuratus, to ocean acidification, a decline in ocean pH that results from the absorption of anthropogenic carbon dioxide (CO2). Larvae were raised from fertilization to pr...

ProteomicsA molecular model of sea urchin reversible adhesion based on quantitative proteomics
Marine bioadhesives have unmatched performances especially in wet environments, being valuable sources of inspiration for industrial and biomedical applications. In sea urchins specialized adhesive organs, called tube feet, mediate adhesion. These are composed by a disc, which produces adhesive and ...

ProteomicsChanges in the proteome of mediterranean sea urchin Paracentrotus lividus due to activation of its immune system
Our aim was to study the immune system of a Mediterranean sea urchin Paracentrotus lividus. Using a label free quantitative mass spectrometry approach we analyzed how bacterial lipopolysaccharide (LPS) is able to modulate the coelomocytes proteome and effect its cellular pathways such as cytoskelet...

ProteomicsProteomic analysis of sea urchin egg provisioning and development
Here we present LC-MS/MS proteomic datasets of Heliocidaris erythrogramma, Heliocidaris tuberculata, and Lytechinus variegatus eggs and larvae. We find dramatic proteomic differences likely associated with life history evolution and between developmental stages. This study provides a complimentary d...
