Paracentrotus
Sea Urchins
Echinodermata
A phylum of the most familiar marine invertebrates. Its class Stelleroidea contains two subclasses, the Asteroidea (the STARFISH or sea stars) and the Ophiuroidea (the brittle stars, also called basket stars and serpent stars). There are 1500 described species of STARFISH found throughout the world. The second class, Echinoidea, contains about 950 species of SEA URCHINS, heart urchins, and sand dollars. A third class, Holothuroidea, comprises about 900 echinoderms known as SEA CUCUMBERS. Echinoderms are used extensively in biological research. (From Barnes, Invertebrate Zoology, 5th ed, pp773-826)

Characterization of sea urchin transglutaminase, a protein regulated by guanine/adenine nucleotides. (1/24)
Transglutaminases (TGs) are calcium-dependent enzymes that catalyze the transamidation of glutamine residues to form intermolecular isopeptide bonds. Nine distinct TGs have been identified in mammals, and three of them (types 2, 3, and 5) are regulated by GTP/ATP and are able to hydrolyze GTP, working as bifunctional enzymes. We have isolated a cDNA clone encoding a TG from a cDNA library prepared from the blastula stage of sea urchin Paracentrotus lividus (PlTG). The cDNA sequence has an open reading frame coding for a protein of 738 amino acids, including a Cys active site and two other residues critical for catalytic activity, His and Asp. We have studied its expression pattern by in situ hybridization and have also demonstrated that the in vitro expressed PlTG had GTP- and ATP-hydrolyzing activity; moreover, GTP inhibited the transamidating activity of this enzyme as it does that of human TG2, TG3, and TG5. (+info)Nuclear envelope assembly is promoted by phosphoinositide-specific phospholipase C with selective recruitment of phosphatidylinositol-enriched membranes. (2/24)
Nuclear envelope (NE) formation in a cell-free egg extract proceeds by precursor membrane vesicle binding to chromatin in an ATP-dependent manner, followed by a GTP-induced NE assembly step. The requirement for GTP in the latter step of this process can be mimicked by addition of bacterial PI-PLC [phosphoinositide (PtdIns)-specific phospholipase C]. The NE assembly process is here dissected in relation to the requirement for endogenous phosphoinositide metabolism, employing recombinant eukaryotic PI-PLC, inhibitors and direct phospholipid analysis using ESI-MS (electrospray ionization mass spectrometry). PtdIns (phosphatidylinositol) species analysis by ESI-MS indicates that the chromatin-bound NE precursor vesicles are enriched for specific PtdIns species. Moreover, during GTP-induced precursor vesicle fusion, the membrane vesicles become partially depleted of the PtdIns 18:0/20:4 species. These data indicate that eukaryotic PI-PLC can support NE formation, and the sensitivity to exogenous recombinant PtdIns-5-phosphatases shows that the endogenous PLC hydrolyses a 5-phosphorylated species. It is shown further that the downstream target of this DAG (diacylglycerol) pathway does not involve PKC (protein kinase C) catalytic function, but is mimicked by phorbol esters, indicating a possible engagement of one of the non-PKC phorbol ester receptors. The results show that ESI-MS can be used as a sensitive means to measure the lipid composition of biological membranes and their changes during, for example, membrane fusogenic events. We have exploited this and the intervention studies to illustrate a pivotal role for PI-PLC and its product DAG in the formation of NEs. (+info)Toxicity of recombinant beta-amyloid prefibrillar oligomers on the morphogenesis of the sea urchin Paracentrotus lividus. (3/24)
A distinctive feature of Alzheimer's disease is the deposition of amyloid beta-protein (Abeta) in senile or diffuse plaques. The 42 residue beta-peptide (Abeta42) is the predominant form found in plaques. In the present work we report a high-yield expression and purification method of production of a recombinant Abeta42. The purified recombinant peptide shows characteristics similar to the synthetic human peptide. Different size aggregates, either small oligomers or larger aggregates, were obtained upon dissolving the recombinant Abeta42 peptide under different conditions at pH 7.2 or pH 3, respectively. We report a new toxicity assay on the morphogenic development of the sea urchin Paracentrotus lividus and study the toxicity of the two kinds of aggregates. Despite the difference between the ionic strength of human extracellular fluid (0.154 mol/l) and artificial sea water (0.48 mol/l), toxicity data collected in this system have an intrinsic relevance. The different ionic strength, in fact, could change the kinetics of oligomer formation, but the effect of morphogenic development reported here is related to the final oligomer sizes. Results of the toxicity assay of Abeta42 on sea urchin development also show a dose-dependent effect. After only 4 h of embryo development, one can note morphological defects in the cell membrane. Retardation of the embryo's development, along with cellular disorders visible inside the blastocoele, can be observed after 1 day of development. Cellular degeneration in two different pathological phenotypes-the occluded blastulae and the occluded prism-is present after 48 h of development. Results show that a greater effect on cell death is induced by the small oligomers stabilized under physiological conditions than at acid pH. In this case only occluded blastulae are found after 48 h of development. (+info)First cell cycles of sea urchin Paracentrotus lividus are dramatically impaired by exposure to extremely low-frequency electromagnetic field. (4/24)
Exposure of fertilized eggs of the sea urchin Paracentrotus lividus to an electromagnetic field of 75-Hz frequency and low amplitudes (from 0.75 to 2.20 mT of magnetic component) leads to a dramatic loss of synchronization of the first cell cycle, with formation of anomalous embryos linked to irregular separation of chromatids during the mitotic events. Because acetylcholinesterase (ACHE) is thought to regulate the embryonic first developmental events of the sea urchin, its enzymatic activity was assayed in embryo homogenates and decreased by 48% when the homogenates were exposed to the same pulsed field. This enzymatic inactivation had a threshold of about 0.75 +/- 0.01 mT. The same field threshold was found for the effect on the formation of anomalous embryos of P. lividus. Moreover, ACHE inhibitors seem to induce the same teratological effects as those caused by the field, while blockers of acetylcholine (ACh) receptors are able to antagonize those effects. We conclude that one of the main causes of these dramatic effects on the early development of the sea urchin by field exposure could be the accumulation of ACh due to ACHE inactivation. The crucial role of the membrane in determining the conditions for enzyme inactivation is discussed. (+info)Nemo-like kinase (NLK) acts downstream of Notch/Delta signalling to downregulate TCF during mesoderm induction in the sea urchin embryo. (5/24)
Studies in Caenorhabditis elegans and vertebrates have established that the MAP kinase-related protein NLK counteracts Wnt signalling by downregulating the transcription factor TCF. Here, we present evidence that during early development of the sea urchin embryo, NLK is expressed in the mesodermal precursors in response to Notch signalling and directs their fate by downregulating TCF. The expression pattern of nlk is strikingly similar to that of Delta and the two genes regulate the expression of each other. nlk overexpression, like ectopic activation of Notch signalling, provoked massive formation of mesoderm and associated epithelial mesenchymal transition. NLK function was found to be redundant with that of the MAP kinase ERK during mesoderm formation and to require the activity of the activating kinase TAK1. In addition, the sea urchin NLK, like its vertebrate counterpart, antagonizes the activity of the transcription factor TCF. Finally, activating the expression of a TCF-VP16 construct at blastula stages strongly inhibits endoderm and mesoderm formation, indicating that while TCF activity is required early for launching the endomesoderm gene regulatory network, it has to be downregulated at blastula stage in the mesodermal lineage. Taken together, our results indicate that the evolutionarily conserved TAK/NLK regulatory pathway has been recruited downstream of the Notch/Delta pathway in the sea urchin to switch off TCF-beta-catenin signalling in the mesodermal territory, allowing precursors of this germ layer to segregate from the endomesoderm. (+info)Cloning of the sea urchin mitochondrial RNA polymerase and reconstitution of the transcription termination system. (6/24)
Termination of transcription is a key process in the regulation of mitochondrial gene expression in animal cells. To investigate transcription termination in sea urchin mitochondria, we cloned the mitochondrial RNA polymerase (mtRNAP) of Paracentrotus lividus and used a recombinant form of the enzyme in a reconstituted transcription system, in the presence of the DNA-binding protein mtDBP. Cloning of mtRNAP was performed by a combination of PCR with degenerate primers and library screening. The enzyme contains 10 phage-like conserved motifs, two pentatricopeptide motifs and a serine-rich stretch. The protein expressed in insect cells supports transcription elongation in a promoter-independent assay. Addition of recombinant mtDBP caused arrest of the transcribing mtRNAP when the enzyme approached the mtDBP-binding site in the direction of transcription of mtDNA l-strand. When the polymerase encountered the protein-binding site in the opposite direction, termination occurred in a protein-independent manner, inside the mtDBP-binding site. Pulse-chase experiments show that mtDBP caused true transcription termination rather than pausing. These data indicate that mtDBP acts as polar termination factor and suggest that transcription termination in sea urchin mitochondria could take place by two alternative modes based on protein-mediated or sequence-dependent mechanisms.

(+info)Paracentrotus is a genus of sea urchins, characterized by their globular test, large, flat ambulacral plates with long tubefeet, and movable spines used for both protection and locomotion, however, it is not commonly used in medical terminology.
I'm sorry for any confusion, but "Paracentrotus" is not a medical term. It is actually the genus name for a specific group of sea urchins, including the common sea urchin "Paracentrotus lividus." I believe there may be some confusion with the term you are looking for. If you have a different term in mind, please provide it so I can give you an accurate definition.
*Medical Definition:* Sea urchins, in the context of dermatology, refer to small, spiny marine animals whose broken-off spines can cause local skin irritation, minor inflammation, and potentially lead to infection if embedded in the skin.
I'm happy to help! However, it seems there might be a bit of confusion here. "Sea urchins" is a common name that refers to a type of marine invertebrate animal, typically characterized by their round, spiny shells. They belong to the class Echinoidea within the phylum Echinodermata.
Medically speaking, there isn't a specific definition for "sea urchins." However, if you come into contact with sea urchins while swimming or diving and accidentally step on them, their spines can puncture your skin and potentially cause an infection. In this case, medical attention may be necessary to remove the embedded spines and treat any resulting infection.
If you were referring to a specific medical term related to sea urchins, could you please clarify? I'm here to help!
Echinodermata is a phylum in the animal kingdom that includes exclusively marine organisms, characterized by radial symmetry, spiny skin, and water-vascular systems, such as sea stars, sea urchins, sand dollars, and sea cucumbers.
Echinodermata is a phylum in the animal kingdom that includes various marine organisms such as sea stars, sea urchins, sand dollars, brittle stars, and sea cucumbers. The name Echinodermata comes from the Greek words "echinos," meaning spiny, and "derma," meaning skin, which refers to the characteristic spiny skin of many echinoderms.
Echinoderms are bilaterally symmetrical as larvae but become radially symmetrical as adults, with their bodies organized around a central axis. They have a unique water vascular system that helps them move and respire, and most species have specialized structures called pedicellariae that help them clean and defend themselves.
Echinoderms are also known for their ability to regenerate lost body parts, and some species can even undergo asexual reproduction through fragmentation. They play important ecological roles in marine ecosystems, including grazing on algae and other organisms, breaking down organic matter, and serving as prey for larger animals.
*Medically unexceptional, the Mediterranean Sea is an intercontinental body of water that separates Southern Europe from Northern Africa and the Middle East, infamous for historical epidemics like plague, which have significantly shaped human health history.*
I'm sorry for any confusion, but the term "Mediterranean Sea" is a geographical term referring to the body of water located between Europe and Africa, and it is not a medical term. It is connected to the Atlantic Ocean by the Strait of Gibraltar in the west and to the Red Sea through the Suez Canal in the east. The Mediterranean Sea is known for its unique climate and biodiversity. If you have any questions related to medical or health topics, I would be happy to try to help with those!
An embryo in nonmammalian species is the developing organism from the first cell division after fertilization until hatching, birth, or the development of a distinct juvenile form, characterized by the differentiation of basic organs and tissues.
A nonmammalian embryo refers to the developing organism in animals other than mammals, from the fertilized egg (zygote) stage until hatching or birth. In nonmammalian species, the developmental stages and terminology differ from those used in mammals. The term "embryo" is generally applied to the developing organism up until a specific stage of development that is characterized by the formation of major organs and structures. After this point, the developing organism is referred to as a "larva," "juvenile," or other species-specific terminology.
The study of nonmammalian embryos has played an important role in our understanding of developmental biology and evolutionary developmental biology (evo-devo). By comparing the developmental processes across different animal groups, researchers can gain insights into the evolutionary origins and diversification of body plans and structures. Additionally, nonmammalian embryos are often used as model systems for studying basic biological processes, such as cell division, gene regulation, and pattern formation.
An ovum is the female reproductive cell, or gamete, in humans and other animals, that is capable of being fertilized by a male sperm to form a zygote and initiate embryonic development. (AFCMS)
An ovum is the female reproductive cell, or gamete, produced in the ovaries. It is also known as an egg cell and is released from the ovary during ovulation. When fertilized by a sperm, it becomes a zygote, which can develop into a fetus. The ovum contains half the genetic material necessary to create a new individual.
