Summary
Diarrhetic shellfish toxins (DSTs) pose a significant public health risk. Advanced OMICs research is crucial for understanding DSTs
Area of Science:
- Marine toxicology
- Environmental chemistry
- Food safety
Background:
- Diarrhetic shellfish toxins (DSTs), including okadaic acid (OA) and dinophysistoxins (DTXs), are prevalent marine toxins impacting coastal regions.
- These toxins, produced by dinoflagellates like *Dinophysis*, accumulate in seafood, posing risks to human health through consumption.
- While OA toxicology and DST accumulation are understood, molecular mechanisms of uptake, distribution, and metabolism remain unclear.
Purpose of the Study:
- To review the contributions of OMICs methodologies to diarrhetic shellfish toxin (DST) research.
- To discuss the future prospects of OMICs in elucidating DST toxicology and impacts.
- To highlight the significance of DST research for public health, food safety, and aquaculture.
Main Methods:
- Systematic analysis of existing literature on DSTs and OMICs applications.
- Review of transcriptomics and proteomics studies related to marine toxin research.
- Assessment of OMICs' effectiveness in identifying metabolic pathways affected by toxins.
Main Results:
- OMICs approaches, including transcriptomics and proteomics, offer powerful tools for studying marine toxin metabolism.
- These methods have begun to reveal insights into the molecular and metabolic processes of DSTs in aquatic organisms.
- Existing knowledge gaps concern the detailed molecular interactions and metabolic fate of DSTs within the food chain.
Conclusions:
- OMICs research is vital for advancing our understanding of DST toxicology and their effects on aquatic ecosystems.
- Continued application of OMICs will improve risk assessment for seafood safety and support sustainable aquaculture.
- Further investigation into DSTs' molecular mechanisms is essential for safeguarding public health.
