Medusa Catostylus Tagi: (I) Preliminary Studies on Morphology, Chemical Composition, Bioluminescence and Antioxidant Activity
MEDUSA CATOSTYLUS TAGI: (I) PRELIMINARY STUDIES ON MORPHOLOGY, CHEMICAL COMPOSITION, BIOLUMINESCENCE AND ANTIOXIDANT ACTIVITY Ana Maria PINTÃO, Inês Matos COSTA, José Carlos GOUVEIA, Ana Rita MADEIRA, Zilda Braga MORAIS Centro de Polímeros Biomédicos, Cooperativa Egas Moniz, Campus Universitário Quinta da Granja, 2829-511, Portugal, [email protected] The Portuguese continental coast, specially Tejo and Sado estuaries, is the habitat of Catostylus tagi [1]. This barely studied medusa was first described in 1869, by Haeckel, and is classified in the Cnidaria phylum, Scyphozoa class, Rhizostomeae order, Catostylidae family, Catostylus genus. According to the European Register of Marine Species, the referred medusa is the only species of the Catostylidae family found in the European continent [2]. C. tagi is particularly abundant during the summer. Several medusas from the Rhizostomae order are traditionally used as food in some oriental countries [3]. Simultaneously, modern medusa utilizations are related to bioluminescence [4], toxicology [5] and biopolymers [6]. The lack of information on this genus along with the recent discoveries of new marine molecules showing anti-arthritic, anti-inflammatory or antioxidant properties motivated our studies [7]. In addition, the abundant medusa biomass could be evaluated as another natural collagen source, alternative to bovine collagen, with its multiple cosmetic and surgical potential uses [8]. The capture and sample preparation methods were optimized in 2003 [9]. Results reported in this poster relate to 65 animals that were captured in the river Sado in August and September of 2004. Macroscopic aspects, like mass and dimensions, were evaluated as well as their C. tagi by J.Gouveia chemical characteristics. -

Contributed equally. y Received: 27 November 2020; Accepted: 17 December 2020; Published: 18 December 2020 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%). -

Abstract: Jellyfish venom is a rich source of bioactive proteins and peptides with various biological activities including antioxidant, antimicrobial and antitumor effects. However, the anti-proliferative activity of the crude extract of Rhopilema nomadica jellyfish venom has not been examined yet. The present study aimed at the investigation of the in vitro effect of R. nomadica venom on liver cancer cells (HepG2), breast cancer cells (MDA-MB231), human normal fibroblast (HFB4), and human normal lung cells (WI-38) proliferation by using MTT assay. The apoptotic cell death in HepG2 cells was investigated using Annexin V-FITC/PI double staining-based flow cytometry analysis, western blot analysis, and DNA fragmentation assays. R. nomadica venom displayed significant Citation: Tawfik, M.M.; Eissa, N.; dose-dependent cytotoxicity on HepG2 cells after 48 h of treatment with IC50 value of 50 µg/mL Althobaiti, F.; Fayad, E.; Abu Almaaty, and higher toxicity (3:5-fold change) against MDA-MB231, HFB4, and WI-38 cells. -
