Identification and Characterization of Novel Proteins from Arizona Bark Scorpion Venom That Inhibit Nav1.8, a Voltage-Gated Sodium Channel Regulator of Pain Signaling

Toxins, 2021
The voltage-gated sodium channel Nav1.8 is linked to neuropathic and inflammatory pain, highlighting the potential to serve as a drug target. However, the biophysical mechanisms that regulate Nav1.8 activation and inactivation gating are not completely ...

Tityus serrulatus Scorpion Venom Induces Apoptosis in Cervical Cancer Cell Lines

Evidence-Based Complementary and Alternative Medicine, Volume 2019, Issue 1, 2019., 2019
Cervical cancer (CC) is classified as the fourth most common type of cancer in women worldwide and remains a serious public health problem in many underdeveloped countries. Human papillomavirus (HPV), mainly types 16 and 18, has been established as a precursory etiologic agent for this type of cancer.

Phosphorescent Animal Forms of Arkansas [PDF]

, 1971
Two phosphorescent animal forms, Euryurus sp. and Centruroides vittatus, were collected with a black light in an attempt to collect phosphorescent spiders. Both the millipede and the scorpion were easily observed by the bright phosphorescent yellow color

Comparative Genomics of Sex‐Determination‐Related Genes Reveals Shared Evolutionary Patterns Between Bivalves and Mammals, but Not Fruit Flies

Molecular Ecology, Volume 34, Issue 20, October 2025.
ABSTRACT The molecular basis of sex determination (SD), while being extensively studied in model organisms, remains poorly understood in many animal groups. Bivalves, a diverse class of molluscs with a variety of reproductive modes, represent an ideal yet challenging clade for investigating SD and the evolution of sexual systems.

A multigene approach to identify the scorpion species (Arachnida: Scorpiones) of Colima, Mexico, with comments on their venom diversity

Revista Mexicana de Biodiversidad
Scorpion species diversity in Colima was investigated with a multigene approach. Fieldwork produced 34 lots of scorpions that were analyzed with 12S rDNA, 16S rDNA, COI, and 28S rDNA genetic markers.

Insect-selective spider toxins targeting voltage-gated sodium channels [PDF]

, 2007
The voltage-gated sodium (Nav) channel is a target for a number of drugs, insecticides and neurotoxins. These bind to at least seven identified neurotoxin binding sites and either block conductance or modulate Nav channel gating.

Invertebrate Bile Acid‐Sensitive Ion Channels and Their Emergence in Bilateria

The FASEB Journal, Volume 39, Issue 8, 30 April 2025.
This graphical abstract presents the evolutionary distribution and functional characteristics of bile acid‐sensing ion channels (BASICs) across bilaterians. A phylogenetic tree illustrates the presence of BASICs in diverse groups, extending beyond previously established mammalian findings.
