Proteomic analysis of sea urchin egg provisioning and development

ABSTRACT: 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 dataset to previous transcriptomic analyses of the same three sea urchin species.

A comparative analysis of egg provisioning using mass spectrometry during rapid life history evolution in sea urchins.

Evolution & development 20190517 4

A dramatic life history switch that has evolved numerous times in marine invertebrates is the transition from planktotrophic (feeding) to lecithotrophic (nonfeeding) larval development-an evolutionary tradeoff with many important developmental and ecological consequences. To attain a more comprehensive understanding of the molecular basis for this switch, we performed untargeted lipidomic and proteomic liquid chromatography-tandem mass spectrometry on eggs and larvae from three sea urchin specie ...[more]

Gene expression alterations in SoxC knockdown sea urchin embryos

Project description:Transcription factor SoxC is required for all neural development in purple sea urchin S. purpuratus embryos. To begin to develop a gene regulatory network for neural development, we used RNA-Seq to compare transcript populations in SoxC knockdown and control embryos. SoxC function was knocked down by morpholino oligo injection. RNA from about 1000 embryos were collected for both control and knockdown samples.

A molecular model of sea urchin reversible adhesion based on quantitative proteomics

Project description: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 de-adhesive secretions for strong reversible attachment, and a motile stem. After detachment, the secreted adhesive remains bound to the substratum as a footprint. Previous studies showed that sea urchin adhesive is composed of proteins and sugars, but so far only one protein, Nectin, was shown to be over-expressed as a transcript in tube feet discs, suggesting its involvement in sea urchin adhesion. Here we use high-resolution quantitative mass-spectrometry technologies to profile Paracentrotus lividus tube feet differential proteome, comparing protein expression levels in its adhesive part (disc) versus the non-adhesive part (stem). This allowed us to identify 163 highly over-expressed disc proteins and propose the first molecular model of sea urchin reversible adhesion. The secreted adhesive proteome was also analyzed, whereby we found that 70% of its components fall within five protein groups, involved in adhesive exocytosis and protection against microbes. Our data also provides evidence that Nectin is not only highly expressed in tube feet discs but is a component of the adhesive itself, thus constituting the first report of a sea urchin tube foot adhesive protein. These results give us an unprecedented insight on the molecular mechanics underlying sea urchins reversible adhesion, opening new doors to develop new, wet-reliable, reversible, efficient, ecological biomimetic adhesives.

The sea urchin larval response to immune challenge with Vibrio diazotrophicus

Project description:Seawater exposure to the gram negative marine bacterium Vibrio diazotrophicus induces a robust cellular response in sea urchin larvae that includes the migration of pigment cells to the gut epithelium, changes in cell behavior and altered gut morphology (Ho et al., 2016; PMID 27192936). To investigate the transcriptional underpinnings of this response, whole transcriptome sequencing was performed on mRNA isolated from larval samples collected at 0, 6, 12 and 24 hr of exposure to V. diazotrophicus. The morphological simplicity of the sea urchin larva provides a systems-level model for identifying biologically relevant transcriptional state changes in response to dysbiosis in the gut lumen.

Global patterns of enhancer activity during sea urchin embryogenesis assessed by eRNA profiling

Project description:We used CAGE-seq (Capped Analysis of Gene Expression with Sequencing) to profile eRNA expression and enhancer activity during embryogenesis of the sea urchin, Strongylocentrotus purpuratus. We identified >18,000 enhancers that were active during late oogenesis and early development and documented a burst of enhancer activation during cleavage and early blastula stages. Most enhancers were located near gene bodies and eRNA expression levels were highest for elements near core promoters. Transcriptional signals from enhancers generally paralleled the expression levels of likely target genes. Furthermore, enhancers near lineage-specific genes contained signatures of inputs from developmental gene regulatory networks deployed in those lineages. A large fraction (60%) of sea urchin enhancers previously shown to be active in transgenic reporter assays were associated with eRNA expression. Moreover, a large fraction (50%) of a representative subset of enhancers identified by eRNA profiling drove tissue-specific gene expression in isolation when tested by reporter assays. Our findings provide an atlas of developmental enhancers in a model sea urchin and support the utility of eRNA profiling as a tool for enhancer discovery and regulatory biology. The data generated in this study are publicly available at Echinobase (www.echinobase.org).

A high-resolution transcriptome map of the sea urchin embryo

Project description:The sea urchin S. purpuratus is a model organism for study of the genomic control circuitry underlying embryonic development. We examined the complete repertoire of genes expressed in the S. purpuratus embryo, up to late gastrula stage, by means of high-resolution custom tiling arrays covering the whole genome. We detected complete spliced structures even for genes known to be expressed at low leveles in only a few cells. At least 11,000 to 12,000 genes are used in embryogenesis. These include most of the genes encoding transcription factors and signaling proteins, as well as some classes of general cytoskeletal and metabolic proteins, but only a minor fraction of genes encoding immune functions and sensory receptors. Thousands of small asymmetric transcripts of unknown function were also detected in intergenic regions throughout the genome. The tiling array data were used to correct and authenticate several thousand gene models during the genome annotation process.
