The biology and evolution of spider venoms [PDF]

Biological Reviews, 2021
ABSTRACTSpiders are diverse, predatory arthropods that have inhabited Earth for around 400 million years. They are well known for their complex venom systems that are used to overpower their prey. Spider venoms contain many proteins and peptides with highly specific and potent activities suitable for biomedical or agrochemical applications, but the key

Toxinology in the proteomics era: a review on arachnid venom proteomics [PDF]

Journal of Venomous Animals and Toxins including Tropical Diseases, 2022
The word venomics was coined to acknowledge the studies that use omics to investigate venom proteins and peptides. Venomics has evolved considerably over the last 20 years. The first works on scorpion or spider venomics were published in the early 2000’s.

Spider-Venom Peptides as Bioinsecticides [PDF]

Toxins, 2012
Over 10,000 arthropod species are currently considered to be pest organisms. They are estimated to contribute to the destruction of ~14% of the world’s annual crop production and transmit many pathogens. Presently, arthropod pests of agricultural and health significance are controlled predominantly through the use of chemical insecticides ...

Spider-Venom Peptides as Therapeutics [PDF]

Toxins, 2010
Spiders are the most successful venomous animals and the most abundant terrestrial predators. Their remarkable success is due in large part to their ingenious exploitation of silk and the evolution of pharmacologically complex venoms that ensure rapid subjugation of prey.

Worldwide Web: High Venom Potency and Ability to Optimize Venom Usage Make the Globally Invasive Noble False Widow Spider Steatoda nobilis (Thorell, 1875) (Theridiidae) Highly Competitive against Native European Spiders Sharing the Same Habitats

Toxins, 2022
Venom compositions include complex mixtures of toxic proteins that evolved to immobilize/dissuade organisms by disrupting biological functions. Venom production is metabolically expensive, and parsimonious use is expected, as suggested by the venom ...

Sphingomyelinase D from Loxosceles laeta Venom Induces the Expression of MMP7 in Human Keratinocytes: Contribution to Dermonecrosis. [PDF]

PLoS ONE, 2016
Envenomation by Loxosceles spider is characterized by the development of dermonecrosis. In previous studies, we have demonstrated that increased expression/secretion of matrix metalloproteinases 2 and 9, induced by Loxosceles intermedia venom Class 2 ...

Return Fantasies: Martial Masculinity, Misogyny and Homosocial Bonding in the Aftermath of Second World War

Gender &History, EarlyView., 2023
Abstract This article explores male popular culture in Australia in the mid‐1940s, particularly men's magazines of the period, to illuminate aspects of the psycho‐sexual dimensions of Australian veterans returning to civil society. The sexual landscape of Australian society had undergone considerable transformation, especially through an increasing ...

Chromosome‐level genome assembly of the black widow spider Latrodectus elegans illuminates composition and evolution of venom and silk proteins

GigaScience, 2022
Background The black widow spider has both extraordinarily neurotoxic venom and three-dimensional cobwebs composed of diverse types of silk. However, a high-quality reference genome for the black widow spider was still unavailable, which hindered deep ...

The venom gland transcriptome of Latrodectus tredecimguttatus revealed by deep sequencing and cDNA library analysis. [PDF]

PLoS ONE, 2013
Latrodectus tredecimguttatus, commonly known as black widow spider, is well known for its dangerous bite. Although its venom has been characterized extensively, some fundamental questions about its molecular composition remain unanswered.
