Venomics-Accelerated Cone Snail Venom Peptide Discovery

Area of Science:

• Marine Biology
• Biochemistry
• Genomics

Background:

• Cone snail venoms are rich sources of bioactive peptides, with over 800 species producing thousands of unique peptides.
• Currently, only a small fraction (~150) of these venom peptides are structurally and functionally characterized.
• Traditional low-throughput methods limit the pace of venom peptide discovery.

Purpose of the Study:

• To explore the application of multi-omics systems approaches (venomics) for accelerating cone snail venom peptide discovery and characterization.
• To address the challenges in integrating transcriptomics, proteomics, and pharmacological data for big dataset analysis.
• To provide insights into the biology and evolution of cone snail venoms.

Main Methods:

• Utilizing multi-omics systems approaches, including transcriptomics and proteomics, for comprehensive venom analysis.
• Employing novel database search tools and visualization techniques for efficient data exploration.
• Integrating diverse omics data with pharmacological information.

Main Results:

• Venomics has significantly expanded the number of identified novel venom peptide sequences from investigated cone snail species.
• The complexity of cone snail venoms is being increasingly unraveled, offering new biological and evolutionary insights.
• Despite advances, a bottleneck exists as most novel conotoxins still require pharmacological characterization.

Conclusions:

• Multi-omics venomics approaches are crucial for accelerating the discovery of bioactive peptides from cone snail venoms.
• Effective integration and analysis of big omics datasets are key challenges for future venomic studies.
• High-throughput peptide production and miniaturized assays are needed to overcome characterization bottlenecks and enhance drug lead discovery from cone snail venoms.
