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. Antimicrobial (including antimollicutes), antioxidant and anticholinesterase activities of Brazilian and Spanish marine organisms – evaluation of extracts and pure compounds
Abstract This work describes the antimicrobial, antioxidant and anticholinesterase activities in vitro of organic extracts from fourteen seaweeds, eleven sponges, two ascidians, one bryozoan, and one sea anemone species collected along the Brazilian and Spanish coast, as well as the isolation of the diterpene (4R, 9S, 14S)-4α-acetoxy-9β,14α-dihydroxydolas

4. 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

5. 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

6. 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

7. 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

8. 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

9. 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

10. Characterization, purification and phylogenetic analysis of a cytolysin from the sea anemone Heteractis magnifica of the Indian Ocean
It is well established that sea anemones comprise a rich source of cytolytic toxins. The present study reports the isolation and characterization of a cytolysin obtained from the sea anemone Heteractis magnifica collected in the Andaman Islands of the Indian Ocean. The crude extract was screened for hemolytic activity by a blood agar plate method and a 6-mm

11. 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

12. Ecologia trÃfica das anÃmonas-do-mar Anthopleura cascaia e Anthopleura krebsi (cnidaria: anthozoa) em duas praias de Pernambuco, Brasil
Studies of trophic ecology are fundamental to understanding the role that the species play in the ecosystem. Sea anemones are important components of reef environments, but few studies address the relationship anemone and its prey. So, it was developed a study on the species Anthopleura cascaia and Anthopleura krebsi on Piedade and Carneiros beach, in Pernam
