Convergent evolution of toxin resistance in animals

open access: yesBiological Reviews, Volume 97, Issue 5, Page 1823-1843, October 2022., 2022
ABSTRACT Convergence is the phenomenon whereby similar phenotypes evolve independently in different lineages. One example is resistance to toxins in animals. Toxins have evolved many times throughout the tree of life. They disrupt molecular and physiological pathways in target species, thereby incapacitating prey or deterring a predator.

Morphometric study and sexual dimorphism analyses in an Iranian population of Scorpio maurus (Arachnida: Scorpionidae)

open access: yesEcology and Evolution, Volume 11, Issue 22, Page 15630-15638, November 2021., 2021
Scorpio maurus was collected and evaluated for morphometric study and sexual dimorphism analyses for the first time in Iran. 53 morphological characters of 15 specimens of each sex of S. maurus were studied. Sexual dimorphism was observed in 21 morphological characters of S. maurus based on statistical analyses.

Gene content evolution in the arthropods [PDF]

open access: yes, 2020
Arthropods comprise the largest and most diverse phylum on Earth and play vital roles in nearly every ecosystem. Their diversity stems in part from variations on a conserved body plan, resulting from and recorded in adaptive changes in the genome ...

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

open access: yesFEBS Open Bio, Volume 11, Issue 7, Page 1867-1892, July 2021., 2021
Buthus occitanus scorpion possesses highly toxic venom. This article describes the first proteomic screening of the Moroccan B. occitanus venom. Our findings highlight the complexity and the toxin diversity of this venom. The most representative compounds are neurotoxins.

Discovery of KV1.3 ion channel inhibitors: Medicinal chemistry approaches and challenges

open access: yesMedicinal Research Reviews, Volume 41, Issue 4, Page 2423-2473, July 2021., 2021
Abstract The KV1.3 voltage‐gated potassium ion channel is involved in many physiological processes both at the plasma membrane and in the mitochondria, chiefly in the immune and nervous systems. Therapeutic targeting KV1.3 with specific peptides and small molecule inhibitors shows great potential for treating cancers and autoimmune diseases, such as ...

Sex‐Biased Gene Expression of Mesobuthus martensii Collected from Gansu Province, China, Reveals Their Different Therapeutic Potentials

open access: yesEvidence-Based Complementary and Alternative Medicine, Volume 2021, Issue 1, 2021., 2021
The scorpions, named Mesobuthus martensii, commonly called Quanxie (全蝎) in Chinese, have been widely used as one of the animal medicines for more than 1,000 years because of the strong toxicity of their venoms. Meanwhile, scorpions are sexually dimorphic in appearance, and many exhibit traits associated with sex‐biased gene expression, including ...

Species delimitation and morphological divergence in the scorpion Centruroides vittatus (Say, 1821): insights from phylogeography. [PDF]

open access: yesPLoS ONE, 2013
Scorpion systematics and taxonomy have recently shown a need for revision, partially due to insights from molecular techniques. Scorpion taxonomy has been difficult with morphological characters as disagreement exists among researchers with character ...
