Abstract
Stonefish (Synanceia spp.) possess a medically significant venom and are widely distributed throughout the Indo-Pacific. Yet, little is known about how the ecology of these animals may influence their venom. The aim of this study was to explore the effect of species and geographic location on stonefish venom composition. We collected the venom of Synanceia horrida (Estuarine Stonefish) and Synanceia verrucosa (Reef Stonefish) from various locations across Australia (Cairns, Brisbane, Caloundra, and Onslow), and Southeast Asia (Kota Kinabalu, and Cebu) and analysed these samples using SDS-PAGE, FPLC, and HPLC. Stonefish have a complex venom comprised of numerous components. Stonefish venom exhibited both similarities and variations in composition within species between geographically isolated populations, as well as between species in a single location. We speculate that the observed geographic and interspecific trends may be driven by similarities and differences in the selective pressures faced by these animals, particularly those associated with predator dynamics. The findings of this study have furthered our understanding of the ecology of stonefish and their toxins.
期刊介绍:
Toxicon has an open access mirror Toxicon: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. An introductory offer Toxicon: X - full waiver of the Open Access fee.
Toxicon''s "aims and scope" are to publish:
-articles containing the results of original research on problems related to toxins derived from animals, plants and microorganisms
-papers on novel findings related to the chemical, pharmacological, toxicological, and immunological properties of natural toxins
-molecular biological studies of toxins and other genes from poisonous and venomous organisms that advance understanding of the role or function of toxins
-clinical observations on poisoning and envenoming where a new therapeutic principle has been proposed or a decidedly superior clinical result has been obtained.
-material on the use of toxins as tools in studying biological processes and material on subjects related to venom and antivenom problems.
-articles on the translational application of toxins, for example as drugs and insecticides
-epidemiological studies on envenoming or poisoning, so long as they highlight a previously unrecognised medical problem or provide insight into the prevention or medical treatment of envenoming or poisoning. Retrospective surveys of hospital records, especially those lacking species identification, will not be considered for publication. Properly designed prospective community-based surveys are strongly encouraged.
-articles describing well-known activities of venoms, such as antibacterial, anticancer, and analgesic activities of arachnid venoms, without any attempt to define the mechanism of action or purify the active component, will not be considered for publication in Toxicon.
-review articles on problems related to toxinology.
To encourage the exchange of ideas, sections of the journal may be devoted to Short Communications, Letters to the Editor and activities of the affiliated societies.
