(Submitter supplied) Ciona intestinalis is an invertebrate animal model system that is well characterized and has many advantages for the study of cardiovascular biology. The regulatory mechanisms of cardiac myocyte proliferation in Ciona are intriguing since Ciona are capable of regeneration throughout their lifespan. To identify important regeneration factors in Ciona, microarray analysis was conducted on RNA from adult Ciona hearts with normal or damaged myocardium using custom Affymetrix GeneChips. more...

(Submitter supplied) Thalidomide has a dark history as a teratogen, but in recent years its derivates have been shown to function as a chemotherapeutic agent. These drugs bind cereblon (CRBN), the substrate receptor of an E3 ubiquitin ligase complex and modify its degradation targets. Despite these insights, remarkably little is known about the normal function of cereblon in development. Here we employ Ciona, an invertebrate chordate, to identify endogenous Crbn targets. more...

(Submitter supplied) We mapped DNA methylation in 580 animal species (535 vertebrates, 45 invertebrates), resulting in 2443 genome-scale, base-resolution DNA methylation profiles of primary tissue samples from various organs. Reference-genome independent analysis of this comprehensive dataset defined a “genomic code” of DNA methylation, which allowed us to predict global and locus-specific DNA methylation from the DNA sequence within and across species. more...

(Submitter supplied) XBP transcription factors are well-known regulators of the the unfolded protein response and are required for plasma cell differentiation. However, recent studies have shown that the XBP1 gene is also expressed in the developing notochord of Ciona and various vertebrates, and to date its role in the formation of this organ is largely uncharacterized. We identified putative targets of Ci-XBP1 through a microarray screen, using RNAs extracted from embryos expressing mutant forms of this transcriptional regulator in the notochord. more...

(Submitter supplied) We recently showed HMX is expressed in bipolar tail neurons (BTN) in early embryos of Ciona intestinalis. In order to assess the function of the homeobox transcription factor in this cell fate, we used an overexpression strategy. ciHMX was overexpressed in the epidermis, followed by RNAseq of experimental and control embryos. We then looked for differential expression of BTN fate markers, testing if HMX is able to regulate BTN fate determination.

(Submitter supplied) The key notochord transcription factor Brachyury was ectopically expressed in Ciona embryos under the control of the FoxAa cis-regulatory region (which drives expression in neural, endodermal and mesenchymal lineages in addition to notochord). Misexpression of Brachyury induced 925 genes compared to a control reporter plasmid (Bra>GFP). There was only modest overlap with a set of notochord-enriched genes previously identified by RNAseq of flow-sorted notochord cells, indicating that Brachyury is not a notochord master regulator gene as strictly defined.

(Submitter supplied) In vertebrates, pluripotent pharyngeal mesoderm progenitors produce the cardiac precursors of the second heart field as well as the branchiomeric head muscles and associated stem cells. However, the cellular and molecular mechanisms underlying the transition from multipotent progenitors to distinct heart and muscle precursors remain obscured by the complexity of vertebrate embryos. Here, using the ascidian Ciona intestinalis as a simple chordate model for cardiopharyngeal development, we show that bipotent progenitors are transcriptionally primed to activate both heart and pharyngeal muscle regulatory programs, which become restricted to the corresponding precursors following a conserved pattern of asymmetric divisions. more...
