1. Cnidom variation through distinct developmental stages in the sea anemone Aulactinia marplatensis (Zamponi, 1977) (Cnidaria: Actiniaria)
The cnidae are the exclusive diagnostic structures of phylum Cnidaria. The inventory of all cnidae types of a particular species is called the cnidom. The study of cnidae has been widely addressed in all classes of cnidarians. Particularly in the order Actiniaria (sea anemones), the study of the composition, size and distribution of cnidae is essential to th

2. Identification of a pore-forming protein from sea anemone Anthopleura dowii Verrill (1869) venom by mass spectrometry
Abstract Background: Pore-forming proteins (PFP) are a class of toxins abundant in the venom of sea anemones. Owing to their ability to recognize and permeabilize cell membranes, pore-forming proteins have medical potential in cancer therapy or as biosensors. In the present study, we showed the partial purification and sequencing of a pore-forming protein f

3. Hemolytic, anticancer and antigiardial activity of Palythoa caribaeorum venom
Abstract Background Cnidarian venoms and extracts have shown a broad variety of biological activities including cytotoxic, antibacterial and antitumoral effects. Most of these studied extracts were obtained from sea anemones or jellyfish. The present study aimed to determine the toxic activity and assess the antitumor and antiparasitic potential of Palythoa

4. In the picture: disulfide-poor conopeptides, a class of pharmacologically interesting compounds
Abstract During evolution, nature has embraced different strategies for species to survive. One strategy, applied by predators as diverse as snakes, scorpions, sea anemones and cone snails, is using venom to immobilize or kill a prey. This venom offers a unique and extensive source of chemical diversity as it is driven by the evolutionary pressure to improve

5. The sea anemone Bunodactis octoradiata (Anthozoa: Actiniaria) from southern Patagonia: morphological study and new records
Bunodactis Verril, 1899 comprises at present 19 nominal species of sea anemones. The validity of the genus is under discussion. The description of the species, Bunodactis octoradiata Carlgren, 1899, is insufficient for reliable identification, and although subsequent works have provided additional information on the species, its description still needs to be

6. Toxins from the Caribbean sea anemone Bunodeopsis globulifera increase cisplatin-induced cytotoxicity of lung adenocarcinoma cells
Background Lung cancer causes 1.4 million deaths worldwide while non-small-cell lung cancer (NSCLC) represents 80-85% of the cases. Cisplatin is a standard chemotherapy against this type of cancer; however, tumor cell resistance to this drug limits its efficacy. Sea anemones produce compounds with pharmacological activities that may be useful for augmenting

7. Purificação e caracterização da fração neurotóxica da peçonha da anêmona do mar Anthopleura cascaia / Purification and characterization of the neurotoxic fraction from the venom of the sea anemone Anthopleura cascaia
A peçonha de anêmonas do mar é uma fonte conhecida de compostos bioativos, incluindo peptídeos, que atuam em canais voltagem-dependentes. Foram descritos 4 tipos de neurotoxinas de anêmonas do mar, que atuam em canais NaV e 4 tipos que atuam em canais KV. Essas toxinas têm permitido discriminar subtipos de canais voltagem-dependentes, estreitamente rel

8. Assessment of biomedical and pharmacological activities of sea anemones Stichodactyla mertensii and Stichodactyla gigantea from Gulf of Mannar Biosphere Reserve, southeast coast of India
Cnidarians comprise an old and diverse animal phylum, and possess a wide variety of biologically active substances. Sea anemones contain a diversity of interesting biologically active compounds including some potent toxins. In the present work, the sea anemones Stichodactyla mertensii and Stichodactyla gigantea, collected from the Mandapam coast, are charact

9. Differential susceptibilities of human lung, breast and skin cancer cell lines to killing by five sea anemone venoms
Although sea anemones are well known for being rich sources of toxins, including cytolysins and neurotoxins, their venoms and toxins have been poorly studied. In the present study, the venoms from five sea anemones (Heteractis crispa, Heteractis magnifica, Heteractis malu, Cryptodendrum adhaesivum and Entacmaea quadricolor) were obtained by the milking techn

10. A anêmona-do-mar Diadumene Stephenson, 1920: um cnidário com potencial invasor na Baía de Paranaguá, PR, Brasil / The sea anemone Diadumene Stephenson, 1920: a cnidarian with an invasion potential in Paranaguá Bay, PR, Brazil
A great number of sea anemones of the genus Diadumene Stephenson, 1920 were found fixated on natural and artificial substrates at the Paranaguá Bay. In 1989, in a study conducted at the same location, the number of anemones of this genus, not identified to a specific level, was much lower. The great abundance of anemones that has currently been observed may

11. AVALIAÇÃO DA ATIVIDADE ANTIBACTERIANA DE COMPONENTES BIOATIVOS PRESENTES EM SECREÇÕES TÓXICAS DE ANÊMONAS MARINHAS / EVALUATION OF ANTIBACTERIAL ACTIVITY OF COMPONENTS IN bioactive SECRETIONS ANEMONES OF TOXIC MARINE
O desenvolvimento da resistência bacteriana aos antibióticos é um fenômeno preocupante que vem sendo muito discutido pelos pesquisadores. Na procura por componentes bioativos com atividade antimicrobiana, os peptídeos catiônicos de origem animal tem se mostrado modelos promissores, seja pela sua potência microbicida, seja pela baixa indução de resis

12. Purification of a 19-kDa pore-forming cytolysin from the sea anemone Heteractis magnifica
Pore-forming cytolysins of 19 kDa from sea anemones present a remarkable cytolytic property. In the present work, a purified 19-kDa cytolysin was obtained from the sea anemone Heteractis magnifica. The purification steps involved ammonium sulfate precipitation and subsequently desalting by dialysis against 10 mM sodium phosphate buffer (pH 7.4), followed by
