Distinct regulatory networks control toxin gene expression in elapid and viperid snakes

BMC Genomics
Background Venom systems are ideal models to study genetic regulatory mechanisms that underpin evolutionary novelty. Snake venom glands are thought to share a common origin, but there are major distinctions between venom toxins from the medically ...

Proteomic Characterization of Two Medically Important Malaysian Snake Venoms, Calloselasma rhodostoma (Malayan Pit Viper) and Ophiophagus hannah (King Cobra)

Toxins, 2018
Calloselasma rhodostoma (CR) and Ophiophagus hannah (OH) are two medically important snakes found in Malaysia. While some studies have described the biological properties of these venoms, feeding and environmental conditions also influence the ...

Coral Venom and Toxins as Protection Against Crown‐of‐Thorns Sea Star Attack

Molecular Ecology, Volume 35, Issue 1, January 2026.
ABSTRACT Crown‐of‐thorns sea star (CoTS) outbreaks are a main cause of hard coral cover decline across the Indo‐Pacific, posing a major threat to the resilience of coral reefs. However, the drivers underlying CoTS feeding on preferred (e.g., Acropora species) versus non‐preferred (e.g., Porites species) are poorly understood. We hypothesised that coral

Comparative Hemostatic Effects of Bothrops spp. and Daboia russelii Venoms

Biochemistry Research International, Volume 2026, Issue 1, 2026.
Venoms from Bothrops species and Daboia russelii are among the leading causes of venom‐induced coagulopathy and snakebite‐related deaths. In this study, we comparatively evaluated the biochemical composition and hemostatic effects of venoms from seven Bothrops species and D. russelii using protein profiling and functional coagulation assays.

Proteomic Characterization and Comparison of Malaysian Tropidolaemus wagleri and Cryptelytrops purpureomaculatus Venom Using Shotgun-Proteomics

Toxins, 2016
Tropidolaemus wagleri and Cryptelytrops purpureomaculatus are venomous pit viper species commonly found in Malaysia. Tandem mass spectrometry analysis of the crude venoms has detected different proteins in T. wagleri and C. purpureomaculatus.

Animal Venom Pharmacological Resources: Exploiting Bioactive Peptides to Target Multi–Drug‐Resistant Bacteria

Biochemistry Research International, Volume 2026, Issue 1, 2026.
Background The escalating rise of multi–drug‐resistant (MDR) bacterial strains significantly threatens global health, creating a “silent pandemic” prompted by natural selection, gene mutation, and horizontal gene transfer. This crisis is worsened by the deficit in the development of new treatments, necessitating the innovative discovery of new potent ...

Animal Venoms as Peptide Libraries for the Discovery of Antiglioblastoma Agents

Biochemistry Research International, Volume 2026, Issue 1, 2026.
Glioblastoma is one of the most aggressive and widely recognized types of brain tumors, characterized by significant cellular and molecular diversity and an inherently aggressive nature. The treatment remains highly challenging, with limited effectiveness and persistently low survival rates.

Molecular characterisation of endogenous snake venom metalloproteinase inhibitors

, 2008
Viper venoms contain one of the most potent mixtures of proteases in natural existence and yet the venom gland and proteins in this mixture are refractory to degradation.

Preliminary Insights into Geographic Variation in Venom Profiles and Functional Activities of Nigerian Snakes, Bitis arietans and Naja nigricollis

Toxins
Snakebite envenoming is a major yet neglected tropical disease in sub-Saharan Africa, where antivenom efficacy is critically limited by intraspecific venom variation shaped by local ecological pressures. Nigeria’s sharply contrasting Sudan Savanna (North)
