Detection of Expressed Otx mRNA Isoforms in Sea Urchins by Mapping NGS Reads to Single-Gene/Transcript Sequences [PDF]

Biology
The identification of mRNA isoforms in biological samples is crucial for studying tissue- and cell-specific isoform expression, activity of tissue-specific promoters, alternative splicing events, and alternative polyadenylation signals in genes.

UVB-induced genotoxic stress activates the DNA damage response and innate immune pathways in sea urchin coelomocytes [PDF]

Frontiers in Immunology
Mechanistic crosstalk between the DNA-damage response (DDR) and the innate immune system is essential to maintain genomic integrity, tissue homeostasis, and organismal resilience.

How ocean warming and acidification affect the life cycle of six worldwide commercialised sea urchin species: A review

Aquaculture, Fish and Fisheries, 2023
Ongoing global changes are expected to affect the worldwide production of many fisheries and aquaculture systems. Because invertebrates represent a relevant industry, it is crucial to anticipate challenges that are resulting from the current ...

New hypotheses of cell type diversity and novelty from orthology-driven comparative single cell and nuclei transcriptomics in echinoderms

eLife, 2023
Cell types are the building blocks of metazoan biodiversity and offer a powerful perspective for inferring evolutionary phenomena. With the development of single-cell transcriptomic techniques, new definitions of cell types are emerging.

Characterization of a novel glutamate dehydrogenase gene and its response to heat stress in the sea urchin Strongylocentrotus intermedius

Aquaculture Reports, 2023
Glutamate dehydrogenase (GDH), a key metabolic enzyme that is ubiquitous across almost all living species, is essential for cell survival. To elucidate the characteristics and functions of the GDH gene in the sea urchin, we cloned and characterized the ...

Effects of five southern California macroalgal diets on consumption, growth, and gonad weight, in the purple sea urchin Strongylocentrotus purpuratus [PDF]

PeerJ, 2015
Consumer growth and reproductive capacity are direct functions of diet. Strongylocentrotid sea urchins, the dominant herbivores in California kelp forests, strongly prefer giant kelp (Macrocystis pyrifera), but are highly catholic in their ability to ...

IL17 factors are early regulators in the gut epithelium during inflammatory response to Vibrio in the sea urchin larva

eLife, 2017
IL17 cytokines are central mediators of mammalian immunity. In vertebrates, these factors derive from diverse cellular sources. Sea urchins share a molecular heritage with chordates that includes the IL17 system.
