Chironex fleckeri (box jellyfish) venom proteins: expansion of a cnidarian toxin family that elicits variable cytolytic and cardiovascular effects.

The Journal of biological chemistry, 2014
The box jellyfish Chironex fleckeri produces extremely potent and rapid-acting venom that is harmful to humans and lethal to prey. Here, we describe the characterization of two C. fleckeri venom proteins, CfTX-A (∼40 kDa) and CfTX-B (∼42 kDa), which were isolated from C.

A Morphospace Exploration Using a General Model of Development Reveals a Basic Set of Morphologies for Early Animal Development and Evolution

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 344, Issue 2, Page 45-58, March 2025.
This work used the model EmbryoMaker to explore the most basic set of morphologies that can be produced from spherical initial conditions by activating cell properties and behaviors in simple genetic territories. We found five possible morphogenetic transformations: invagination, evagination, elongation, condensation and anisotropic growth.

Origin and evolution of microvilli

Biology of the Cell, Volume 116, Issue 11, November 2024.
Microvilli are widespread organelles of animal cells that frequently play a role in sensation and feeding. Ansel et al. reconstitute their origin and evolution by performing a broad morphological survey of microvilli in animals and their unicellular relatives, coupled with a bioinformatic study of the phylogenetic distribution of the main microvillar ...

Hemolytic, anticancer and antigiardial activity of Palythoa caribaeorum venom

Journal of Venomous Animals and Toxins including Tropical Diseases, 2018
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.

eDNA Is a Useful Environmental Monitoring Tool for Assessing Stream Ecological Health

Environmental DNA, Volume 6, Issue 4, July–August 2024.
Ecosystem health assessments made by traditional biomonitoring techniques were compared to those made using eDNA at 53 sites throughout New Zealand. We found a high degree of correlation and convergence between biotic indices calculated from traditional biomonitoring techniques and from eDNA.

A sedimentary DNA record of the Atacama Trench reveals biodiversity changes in the most productive marine ecosystem

Global Change Biology, Volume 30, Issue 7, July 2024.
Using DNA deposited in deep‐sea sediments, we examine how marine biodiversity has changed over the last 150 years in Chilean waters. We find a unique period aligning with high fishing and extreme climatic events that reduces overall diversity. Furthermore, we find an effect of sea surface temperature and El Nino events over diversity, providing an idea

Structure–function relationships in ShKT domain peptides: ShKT‐Ts1 from the sea anemone Telmatactis stephensoni

Proteins: Structure, Function, and Bioinformatics, Volume 92, Issue 2, Page 192-205, February 2024.
Abstract Diverse structural scaffolds have been described in peptides from sea anemones, with the ShKT domain being a common scaffold first identified in ShK toxin from Stichodactyla helianthus. ShK is a potent blocker of voltage‐gated potassium channels (KV1.x), and an analog, ShK‐186 (dalazatide), has completed Phase 1 clinical trials in plaque ...
