Sea anemones are sessile invertebrates of the phylum Cnidaria and their survival evolutive success highly related to ability produce quickly inoculate venom, with presence potent toxins. In this study, a multi-omics approach was applied characterize protein composition tentacles mucus Bunodosoma caissarum, species sea anemone from Brazilian coast. The transcriptome resulted in 23,444 annotated genes, which 1% showed similarity toxins or proteins toxin activity. proteome analysis, 430 polypeptides were consistently identified: 316 them more abundant while 114 enriched mucus. Tentacle mostly enzymes, followed by DNA- RNA-associated proteins, most addition, peptidomics allowed identification large small fragments mature toxins, neuropeptides, intracellular peptides. conclusion, integrated omics identified previously unknown uncharacterized genes addition 23 toxin-like therapeutic potential, improving understanding tentacle anemones.

Abstract The symbiotic relationships between coral animal host and autotrophic dinoflagellates are based on the mutual exchange tight control of nutritional inputs supporting successful growth. corals Sinularia heterospiculata Acropora aspera were cultivated using a flow-through circulation system supplying seawater during cold warm seasons year, then sorted into cells symbionts subjected to phylogenetic, morphological, advanced lipid analyses. Here we show, that lipidomes Cladocopium C1/C3 acroporide-specific hosted by corals, determined lipidomic features different thermosensitivity unique betaine- phospholipid molecular species. Phosphatidylserines ceramiaminoethylphosphonates not detected in predominantly localized inner leaflet S. plasma membrane. transmembrane distribution phosphatidylethanolamines changes possibly contributing mutualistic across this membrane complex provide with secure adaptive mechanism ecological benefits.

Abstract Cnidarians are the first phylum of metazoans to exhibit a functional mucus layer. In evolution, mucous cells perform classical secretory function and act as sentinels for external insults, particularly in mammals. However, this topic has not been much analysed lower metazoans. This study aims investigate role Actinia equina (Anthozoa, Hexacorallia) (Linnaeus, 1758) by using confocal microscopy bioinformatics. The results show colocalization Toll‐like receptor 2 (TLR2) Mucin2 (MUC2) on these cells, suggesting crosstalk between defence response secretion cnidarians. Furthermore, presence TLR2 surface suggests their involvement host responses, occurs vertebrates. Moreover, through silico analysis, we confirmed orthologous genes tested antibodies, providing additional evidence support our from an evolutionary perspective. These data suggest that play defensive throughout helping us understand how have developed adapted across phylogenesis. information also provides new insights into strategies invertebrates clarifies history.
