Abstract
The proliferation of toxic organisms caused by changes in the marine environment, coupled with the rising human activities along the coastal lines, has resulted in an increasing number of stinging incidents, posing a serious threat to public health. Here, we evaluated the systemic toxicity of the venom in jellyfish Chrysaora quinquecirrha at both cellular and animal levels, and found that jellyfish tentacle extract (TE) has strong lethality accompanied by abnormal elevation of blood biochemical indicators and pathological changes. Joint analysis of transcriptome and proteome indicated that metalloproteinases are the predominant toxins in jellyfish. Specially, two key metalloproteinases DN6695_c0_g3 and DN8184_c0_g7 were identified by mass spectrometry of the red blood cell membrane and tetracycline hydrochloride (Tch) inhibition models. Structurally, molecular docking and kinetic analysis are employed and observed that Tch could inhibit the enzyme activity by binding to the hydrophobic pocket of the catalytic center. In this study, we demonstrated that Tch impedes the metalloproteinase activity thereby reducing the lethal effect of jellyfish, which suggests a potential strategy for combating the health threat of marine toxic jellyfish.

Hérnández-Elizárraga VH, Vega-Tamayo JE, Olguín-López N, Ibarra-Alvarado C, Rojas-Molina A. Transcriptomic and proteomic analyses reveal the first occurrence of diverse toxin groups in Millepora alcicornis. J Proteomics 2023; 288:104984. [PMID: 37536522 DOI: 10.1016/j.jprot.2023.104984] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Revised: 06/22/2023] [Accepted: 07/25/2023] [Indexed: 08/05/2023]
Abstract
Millepora alcicornis is a reef-forming cnidarian widely distributed in the Mexican Caribbean. Millepora species or "fire corals" inflict a painful stinging reaction in humans when touched. Even though hundreds of organic and polypeptide toxins have been characterized from sea anemones and jellyfish, there are few reports regarding the diversity of toxins synthesized by fire corals. Here, based on transcriptomic analysis of M. alcicornis, several predicted proteins that show amino acid sequence similarity to toxins were identified, including neurotoxins, metalloproteases, hemostasis-impairing toxins, serin proteases, cysteine-rich venom proteins, phospholipases, complement system-impairing toxins, phosphodiesterases, pore-forming toxins, and L-aminoacid oxidases. The soluble nematocyst proteome of this organism was shown to induce hemolytic, proteolytic, and phospholipase A2 effects by gel zymography. Protein bands or spots on 1D- and 2D-PAGE gels corresponding to zones of hemolytic and enzymatic activities were excised, subjected to in-gel digestion with trypsin, and analyzed by mass spectrometry. These proteins exhibited sequence homology to PLA2s, metalloproteinases, pore-forming toxins, and neurotoxins, such as actitoxins and CrTX-A. The complex array of venom-related transcripts that were identified in M. alcicornis, some of which are first reported in "fire corals", provide novel insight into the structural richness of Cnidarian toxins and their distribution among species. SIGNIFICANCE: Marine organisms are a promising source of bioactive compounds with valuable contributions in diverse fields such as human health, pharmaceuticals, and industrial application. Currently, not much attention has been paid to the study of fire corals, which possess a variety of molecules that exhibit diverse toxic effects and therefore have great pharmaceutical and biotechnological potential. The isolation and identification of novel marine-derived toxins by classical approaches are time-consuming and have low yields. Thus, next-generation strategies, like base-'omics technologies, are essential for the high-throughput characterization of venom compounds such as those synthesized by fire corals. This study moves the field forward because it provides new insights regarding the first occurrence of diverse toxin groups in Millepora alcicornis. The findings presented here will contribute to the current understanding of the mechanisms of action of Millepora toxins. This research also reveals important information related to the potential role of toxins in the defense and capture of prey mechanisms and for designing appropriate treatments for fire coral envenomation. Moreover, due to the lack of information on the taxonomic identification of Millepora, the insights presented here can advise the taxonomic classification of the species of this genus.

Multiomic Approach for Bioprospection: Investigation of Toxins and Peptides of Brazilian Sea Anemone Bunodosoma caissarum. Mar Drugs 2023; 21:md21030197. [PMID: 36976246 PMCID: PMC10058367 DOI: 10.3390/md21030197] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2023] [Revised: 03/16/2023] [Accepted: 03/20/2023] [Indexed: 03/29/2023] Open
Abstract
Sea anemones are sessile invertebrates of the phylum Cnidaria and their survival and evolutive success are highly related to the ability to produce and quickly inoculate venom, with the presence of potent toxins. In this study, a multi-omics approach was applied to characterize the protein composition of the tentacles and mucus of Bunodosoma caissarum, a species of sea anemone from the Brazilian coast. The tentacles transcriptome resulted in 23,444 annotated genes, of which 1% showed similarity with toxins or proteins related to toxin activity. In the proteome analysis, 430 polypeptides were consistently identified: 316 of them were more abundant in the tentacles while 114 were enriched in the mucus. Tentacle proteins were mostly enzymes, followed by DNA- and RNA-associated proteins, while in the mucus most proteins were toxins. In addition, peptidomics allowed the identification of large and small fragments of mature toxins, neuropeptides, and intracellular peptides. In conclusion, integrated omics identified previously unknown or uncharacterized genes in addition to 23 toxin-like proteins of therapeutic potential, improving the understanding of tentacle and mucus composition of sea anemones.

ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2022; 233:113315. [PMID: 35189521 DOI: 10.1016/j.ecoenv.2022.113315] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/14/2021] [Revised: 02/10/2022] [Accepted: 02/12/2022] [Indexed: 06/14/2023]
Abstract
BACKGROUND The application of multi-omics technologies provides a new perspective to solve three main problems including species identification, toxin screening and effective antagonist conformation in the studies of marine toxic jellyfish. METHODS A series of transcriptome-proteome based analysis accompanied with toxicity evaluations were performed for the ornamental jellyfish Phacellophora camtschatica. RESULTS Through combined morphological observation and Cytochrome c oxidase subunit Ⅰ (CO1) molecular alignment, the sample jellyfish was identified as P. camtschatica. A total of 25,747 unigenes and 3058 proteins were obtained from the successfully constructed transcriptome and proteome, in which 6869 (26.68%) and 6618 (25.70%) unigenes, as well as 2536 (82.93%) and 2844 (93.00%) proteins were annotated against the databases of Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG), respectively. The jellyfish displayed obvious in vivo lethal effects with significant increases of multi-organ functional indexes as well as in vitro activities. Total of 62 toxins from 120 toxin-related unigenes were screened including 16 metalloproteases, 11 phospholipases and others. Moreover, 11 toxins were further screened by using the erythrocyte model, where the zinc metalloproteinase nas-15-like (1) was the most abundant. Finally, Diltiazem greatly improved the survival rate while EDTA slightly prolonged the survival time in ICR mice. CONCLUSION P. camtschatica is a poisonous jellyfish with diversified toxic components, in which metalloproteinase probably plays an important role in toxicities, and excessive Ca2+ entry may be the main mechanism of systemic lethal toxicity.

De novo transcriptomic and proteomic analysis and potential toxin screening of Mesobuthus martensii samples from four different provinces. JOURNAL OF ETHNOPHARMACOLOGY 2021; 265:113268. [PMID: 32810618 DOI: 10.1016/j.jep.2020.113268] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/26/2020] [Revised: 07/04/2020] [Accepted: 08/09/2020] [Indexed: 06/11/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE As well-known medicinal materials in traditional Chinese medicine, scorpions, commonly called as Quanxie () in Chinese, have been widely used to treat several diseases such as rheumatoid arthritis, apoplexy, epilepsy and chronic pain for more than a thousand years. Not only in the ancient times, the scorpions have also been recorded nowadays in the Pharmacopoeia of the People's Republic of China since 1963. AIM OF STUDY This study aims to explore the differences in composition of the venom of scorpions from different regions by using the method of transcriptomics and proteomics. MATERIALS AND METHODS Whole de novo transcriptomes, proteomics and their bioinformatic analyses were performed on samples of the scorpion Mesobuthus martensii and their venoms from four different provinces with clear geographical boundaries, including Hebei, Henan, Shandong and Shanxi. RESULTS The four captured samples had the same morphology, and the conserved CO-1 sequence matched that of M. martensii. A total of 141,003 of 174,653 transcripts were identified as unigenes, of which we successfully annotated 51,627 (36.61%), 21,970 (15.58%), 7,168 (5.08%), and 45,263 (32.10%) unigenes with the NR, GO, KEGG and SWISSPROT databases, respectively, while a total of 427 proteins were collected from the protein extracted from venoms. Both GO and KEGG annotations exhibited only slight differences among the four samples while the expression level of gene and protein was quite different. A total of 249 toxin-related unigenes were successfully screened, including 41 serine proteases and serine protease inhibitors, 39 potassium channel toxins, 38 phospholipases, 16 host defense peptides, 9 metalloproteases, and 50 other toxins. Although the toxin species were similar among the four samples, the gene expression of each toxin varied considerably, for example, the scorpion from HB province has the most abundant expression quality in sequences c48391_g1, c55239_g1 and c47749_g1 while the lowest expressions of c51178_g1, c62033_g3 and c63754_g2. CONCLUSION The regional differences in the transcriptomes and proteomes of M. martensii are mainly from expression levels e.g. toxins rather than expression species, of which the method can be further extended to evaluate the qualities of traditional Chinese medicines obtained from different regions.

Abstract
Venomics, the study of biological venoms, could potentially provide a new source of therapeutic compounds, yet information on the venoms from marine organisms, including cnidarians (sea anemones, corals, and jellyfish), is limited. This study identified the putative toxins of two species of jellyfish—edible jellyfish Rhopilema esculentum Kishinouye, 1891, also known as flame jellyfish, and Amuska jellyfish Sanderia malayensis Goette, 1886. Utilizing nano-flow liquid chromatography tandem mass spectrometry (nLC–MS/MS), 3000 proteins were identified from the nematocysts in each of the above two jellyfish species. Forty and fifty-one putative toxins were identified in R. esculentum and S. malayensis, respectively, which were further classified into eight toxin families according to their predicted functions. Amongst the identified putative toxins, hemostasis-impairing toxins and proteases were found to be the most dominant members (>60%). The present study demonstrates the first proteomes of nematocysts from two jellyfish species with economic and environmental importance, and expands the foundation and understanding of cnidarian toxins.

Abstract
Tube anemones, or cerianthids, are a phylogenetically informative group of cnidarians with complex life histories, including a pelagic larval stage and tube-dwelling adult stage, both known to utilize venom in stinging-cell rich tentacles. Cnidarians are an entirely venomous group that utilize their proteinaceous-dominated toxins to capture prey and defend against predators, in addition to several other ecological functions, including intraspecific interactions. At present there are no studies describing the venom for any species within cerianthids. Given their unique development, ecology, and distinct phylogenetic-placement within Cnidaria, our objective is to evaluate the venom-like gene diversity of four species of cerianthids from newly collected transcriptomic data. We identified 525 venom-like genes between all four species. The venom-gene profile for each species was dominated by enzymatic protein and peptide families, which is consistent with previous findings in other cnidarian venoms. However, we found few toxins that are typical of sea anemones and corals, and furthermore, three of the four species express toxin-like genes closely related to potent pore-forming toxins in box jellyfish. Our study is the first to provide a survey of the putative venom composition of cerianthids and contributes to our general understanding of the diversity of cnidarian toxins.

Abstract
BACKGROUND We successfully captured a kind of gelatinous organism DA-6 from Antarctic water, extracted its total RNAs and proteins, and performed species identification through a combination of transcriptomics and proteomics in this study. METHODS The gelatinous organism DA-6 was captured 200 m underwater in Antarctica. Total RNA was extracted to construct the transcriptome and the proteins were identified by LC-MS/MS. RESULTS DA-6 was identified as an Antarctic Salpa sp. through morphological examination and MT-CO1 phylogenetic analysis. A total of 47,183 unigenes were harvested through transcriptome. We also successfully annotated 11,954 (25.34%), 10,006 (22.21%), 4469 (9.47%) and 4901 (9.71%) unigenes with NR, SwissProt, GO and KEGG databases, respectively. In the proteomic analysis, a total of 4680 peptides and 1280 proteins were harvested using the transcriptome as the reference database. A number of both 549 (31.98%) proteins reannotated against the GO and KEGG databases. Moreover, a number of 5 toxic proteins matched from the 89 toxin-related unigenes were successfully screened, including 2 metalloproteinases, 1 serine protease, 1 serine protease inhibitor and 1 aflatoxin. CONCLUSION Our study is the first to identify an Antarctic Salpa sp. according to the combination of de novo transcriptomics and proteomics, which can further be served as a public database for the identification of potential polar Salpa-derived lead compounds. In addition to morphology and CO1, the combined analysis of transcriptome and proteome can also be used as a value method for new species identify e.g. Salpa sp.

Abstract
Hemocyanin (Hc) is a multifunctional macromolecule involved in oxygen transport and non-specific immunity in shrimp. Hc is crucial in physiology and nutrition linked with optimal performance in aquaculture production systems. In medicine, Hc has been approved for clinical use in humans as adjuvant and anticancer therapeutic. In contrast, Hc has also been identified as one of the proteins causing anaphylaxis following shrimp consumption. The role of individual Hc isoforms remains unknown due to a lack of resolved Hc isoforms. We successfully identified eleven different Penaeus monodon hemocyanin (PmoHc) γ isoforms including two truncated isoforms (50 and 20 kDa) and one PmoHc β isoform in haemolymph using proteomics informed by transcriptomics. Amino acid sequence homology ranged from 24 to 97% between putative PmoHc gene isoforms. Hc isoforms showed specific patterns of transcript expression in shrimp larval stages and adult hepatopancreas. These findings enable isoform level investigations aiming to define molecular mechanisms underpinning Hc functionality in shrimp physiology and immunity, as well as their individual immunogenic role in human allergy. Our research demonstrates the power of proteomics informed by transcriptomics to resolve isoform complexity in non-model organisms and lay the foundations for improved performance within the aquaculture industry and advance allergenic applications in medicine. SIGNIFICANCE: The roles of hemocyanin (Hc) in shrimp homeostasis and immunity as well as in human allergy are not well understood because the complexity of Hc isoforms has remained unresolved. Our results have confirmed the existence of at least 12 individual Hc isoforms in shrimp haemolymph and validated putative Hc gene assemblies from transcriptomics. Our findings will enable monitoring the expression of specific Hc isoforms in shrimp haemolymph during different environmental, nutritional and pathogenic conditions, thus providing insights into isoform specific functional roles. In medicine, the potential allergenicity of each Hc isoform could be determined and advance allergenic applications. Lastly, since Hc comprises up to 95% of the total protein in haemolymph, these isoforms become ideal targets for prawn provenance, traceability and food contamination studies.
