Pond frog as a predator of hornet workers: High tolerance to venomous stings

Ecosphere, Volume 16, Issue 12, December 2025.
Abstract Some animals use stingers to repel attackers, and some predators have evolved tolerance to such stings, enabling them to consume venomous prey. For example, social wasps, such as hornets, use modified ovipositors as venomous stingers to inject venom, which can cause intense pain in humans.

Mass spectrometry‐based top‐down and bottom‐up approaches for proteomic analysis of the Moroccan Buthus occitanus scorpion venom

FEBS Open Bio, 2021
Buthus occitanus (B. occitanus) is one of the most dangerous scorpions in the world. Despite the involvement of B. occitanus scorpion in severe cases of envenomation in Morocco, no study has focused yet on the proteomic composition of the Moroccan B ...

Structure, function and mechanistic aspects of scorpion venom peptides - A boon for the development of novel therapeutics

European Journal of Medicinal Chemistry Reports, 2022
Venom of scorpions is very expensive and lethal, yet with innumerable and exciting potential as a source for the development of biotherapeutics. One of the chief components of scorpion venom is the ‘peptides’ which have shown diverse array of biological ...

A Cell‐Penetrating Scorpion Venom Peptide Disrupts the HSP90β‐PPARα Interaction to Ameliorate Metabolic Dysfunction‐Associated Steatotic Liver Disease

iMetaMed, Volume 1, Issue 2, December 2025.
In MASLD, increased HSP90β interacts with PPARα, thereby inhibiting PPARα activation via the inhibition of its nuclear translocation. BmK Tx‐2, a cell‐penetrating peptide from Buthus martensii Karsch scorpion venom, enters hepatocytes via macropinocytosis and escapes endosomes to bind HSP90β.

Intervertebral Disc Proteoglycans: Multifunctional Tissue Stabilizing and Instructional Cell Regulatory Proteins That Control Tissue Homeostasis

JOR SPINE, Volume 8, Issue 4, December 2025.
Matrix and cell‐associated proteoglycans are important tissue‐stabilizing, weight‐bearing, and tension‐resisting proteins in the intervertebral disc. Their glycosaminoglycan components have growth factor binding and cell‐instructive properties that allow cells to regulate tissue composition and function.

Mass landscapes of seven scorpion species: the first analyses of Australian species with 1,5-DAN matrix [PDF]

, 2012
Scorpion venoms have been studied for over fifty years; however, the majority of research has focussed primarily on medically important Buthidae species. Additionally, venoms of the estimated 200 species of scorpion native to Australia have received very

Protease inhibitors from marine venomous animals and their counterparts in terrestrial venomous animals [PDF]

, 2013
The Kunitz-type protease inhibitors are the best-characterized family of serine protease inhibitors, probably due to their abundance in several organisms.

Structural similarities reveal an expansive conotoxin family with a two‐finger toxin fold

Protein Science, Volume 34, Issue 11, November 2025.
Abstract Venomous animals have evolved a diverse repertoire of toxins with considerable pharmaceutical potential. The rapid evolution of peptide toxins, such as the conotoxins produced by venomous marine cone snails, often complicates efforts to infer their evolutionary relationships based solely on sequence information.

rBmαTX14 Increases the Life Span and Promotes the Locomotion of Caenorhabditis Elegans. [PDF]

PLoS ONE, 2016
The scorpion has been extensively used in various pharmacological profiles or as food supplies. The exploration of scorpion venom has been reported due to the presence of recombinant peptides. rBmαTX14 is an α-neurotoxin extracted from the venom gland of
