Pharmacological characterization of cnidarian extracts from the Caribbean Sea: evaluation of anti-snake venom and antitumor properties [PDF]

Journal of Venomous Animals and Toxins including Tropical Diseases, 2018
Background Cnidarians produce toxins, which are composed of different polypeptides that induce pharmacological effects of biotechnological interest, such as antitumor, antiophidic and anti-clotting activities.

Cytotoxic Effects of Cnidarian Venoms: One Cancer, Two Cell Lines [PDF]

Marine Biotechnology
Abstract This study aimed to evaluate the cytotoxic effects of jellyfish venoms on two different colon cancer cell lines and to compare their activity with that observed in a healthy colon cell line used as a control. Venoms were isolated from specimens of Aurelia aurita ,

The cnidarian parasite Ceratonova shasta utilizes inherited and recruited venom-like compounds during infection [PDF]

PeerJ, 2021
Background Cnidarians are the most ancient venomous organisms. They store a cocktail of venom proteins inside unique stinging organelles called nematocysts.

POTENTIAL USEFULNESS OF PLANT EXTRACTS TO COUNTERACT CNIDARIAN VENOMS

, 2021
Cnidarians toxins are known to have a high impact on public health in marine coastal zones the world over. Consequently these toxins are now recognised as an important focus for research on their therapeutic potential. To date several therapeutically important activities have been experimentally identified in cnidarian extracts and venoms. However, the

Hemolytic venoms from marine cnidarian jellyfish - an overview.

Journal of venom research, 2014
Cnidarian jellyfish are viewed as an emergent problem in several coastal zones throughout the world. Recurrent outbreaks pose a serious threat to tourists and bathers, as well as to sea-workers, involving health and economical aspects. As a rule, cnidarian stinging as a consequence of nematocyst firing induces merely local symptoms but cardiovascular ...

Cnidarian Venoms in the Omics Era: Toxin Discovery and Bioactive Potential

Marine Drugs
Cnidaria is a phylum of aquatic invertebrates that includes jellyfish, sea anemones and corals. Their venoms are among the oldest in the animal kingdom and an important source of bioactive molecules.

Heated Debates: Hot-Water Immersion or Ice Packs as First Aid for Cnidarian Envenomations?

Toxins, 2016
Cnidarian envenomations are an important public health problem, responsible for more deaths than shark attacks annually. For this reason, optimization of first-aid care is essential.

Cnidarian venoms and alternative research methods: From cell damage to possible applications.

, 2017
Cnidaria are venomous aquatic organisms, whose dangerousness is remarkable among marine species. Cnidarian jellyfish sometimes show extensive proliferations – outbreaks or blooms – along with occasional strandings on beaches. Due to the invisibility of several diaphanous and completely transparent species, sometimes they are not seen by bathers or sea ...

Implications of bleaching on cnidarian venom ecology

Toxicon: X, 2022
Cnidarian bleaching research often focuses on the effects on a cnidarian's physiological health and fitness, whilst little focus has been towards the impacts of these events on their venom ecology. Given the importance of a cnidarian's venom to their survival and the increasing threat of bleaching events, it is important to understand the effects that ...

Evolution and diversification of the cnidarian venom system [PDF]

Molecular Biology and Evolution, 2016
The phylum Cnidaria (corals, sea pens, sea anemones, jellyfish and hydroids) is the oldest venomous animal lineage (~750 million years old), making it an ideal phylum to understand the origin and diversification of venom. Cnidarians are characterised by specialised cellular structures called cnidae, which they utilise to inject mixtures of bioactive ...
