Transcriptomic basis for an antiserum against Micrurus corallinus (coral snake) venom [PDF]

, 2009
Background Micrurus corallinus (coral snake) is a tropical forest snake belonging to the family Elapidae. Its venom shows a high neurotoxicity associated with pre- and post-synaptic toxins, causing diaphragm paralysis, which may result in death. In spite

CUSCO: A Tool for Curating Single‐Copy Orthologs and Extracting Marker Genes for Phylogenetic Tree Construction With Extra Samples

Ecological Research, Volume 40, Issue 6, November 2025.
We developed the CUSCO pipeline. It enables rapid construction of a phylogenetic tree using whole genome sequences and identifies useful marker genes for additional samples. It can handle polyploid genomes. ABSTRACT Single‐copy orthologs are often used to reconstruct phylogenetic trees of life. A set of single‐copy orthologs can be prepared by building

Exceptional Visual‐Opsin Coexpression and Phenotypic Diversity in Outer‐Retinal Photoreceptors of Caenophidian Snakes

Journal of Comparative Neurology, Volume 533, Issue 10, October 2025.
In snakes, profound differences in retinal architecture are observed between diurnal and nocturnal species. Additionally, in the rod‐dominated retinas of nocturnal snakes, coexpression of the cone opsins SWS1 and LWS in individual cones is common, while rhodopsin (RH1) is restricted to typical rods.

Proteomic and functional variation within black snake venoms (Elapidae: Pseudechis ) [PDF]

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2018
Pseudechis (black snakes) is an Australasian elapid snake genus that inhabits much of mainland Australia, with two representatives confined to Papua New Guinea. The present study is the first to analyse the venom of all 9 described Pseudechis species (plus one undescribed species) to investigate the evolution of venom composition and functional ...

Fossil snakes (Squamata, Serpentes) from the tar pits of Venezuela: taxonomic, palaeoenvironmental, and palaeobiogeographical implications for the North of South America during the Cenozoic/Quaternary boundary [PDF]

PeerJ, 2018
Background Tar seep deposits in South America historically are well-known for their rich record of fossil mammals, contrasting with only a few formal reports of reptile remains. Here we report a new snake fauna recovered from two tar pits from Venezuela.

The Proteome of African Spitting and Non‐Spitting Cobra Venoms and Cytotoxicity Against Pancreatic Cancer Cells

Journal of Applied Toxicology, Volume 45, Issue 10, Page 2055-2067, October 2025.
ABSTRACT African cobra (Naja spp.) venom contains toxins dominated by proteins and peptides with inter‐ and intra‐specific variations. There are several FDA‐approved drugs from snake venom toxins from other regions, including South America and Asia. Profiling the proteomes of medically important African cobra venoms from different locations will aid in
