Effects of the Marine Biotoxins Okadaic Acid and Dinophysistoxins on Fish [PDF]

Journal of Marine Science and Engineering, 2021
Natural high proliferations of toxin-producing microorganisms in marine and freshwater environments result in dreadful consequences at the socioeconomically and environmental level due to water and seafood contamination. Monitoring programs and scientific evidence point to harmful algal blooms (HABs) increasing in frequency and intensity as a result of

Deciphering interactions between the marine dinoflagellate Prorocentrum lima and the fungus Aspergillus pseudoglaucus. [PDF]

Environ Microbiol, 2023
Abstract The comprehension of microbial interactions is one of the key challenges in marine microbial ecology. This study focused on exploring chemical interactions between the toxic dinoflagellate Prorocentrum lima and a filamentous fungal species, Aspergillus pseudoglaucus, which has been isolated from the microalgal culture.

Biochemical characterization and inhibitory effects of dinophysistoxin-1, okadaic acid and microcystine l-r on protein phosphatase 2a purified from the mussel Mytilus chilensis.

Biological Research, 2000
Protein phosphatases are involved in many cellular processes. One of the most abundant and best studied members of this class is protein phosphatase type-2A (PP2A). In this study, PP2A was purified from the mussel Mytilus chilensis.

Marine toxins and the cytoskeleton: okadaic acid and dinophysistoxins [PDF]

The FEBS Journal, 2008
Okadaic acid (OA) and its analogs, the dinophysistoxins, are potent inhibitors of protein phosphatases 1 and 2A. This action is well known to cause diarrhea and gastrointestinal symptons when the toxins reach the digestive tract by ingestion of mollusks. A less well‐known effect of these group of toxins is their effect in the cytoskeleton.

Clarification of the C-35 Stereochemistries of Dinophysistoxin-1 and Dinophysistoxin-2 and Its Consequences for Binding to Protein Phosphatase [PDF]

Chemical Research in Toxicology, 2007
Okadaic acid analogues are well known as protein phosphatase inhibitors and occur naturally in marine shellfish feeding on dinoflagellates of the genus Dinophysis, leading to diarrhetic shellfish poisoning of shellfish consumers. Knowledge of the correct structures for these toxins is important in understanding their toxicology, biochemistry, and ...

Magnetic Covalent Organic Framework Composites for Wastewater Remediation

Small, Volume 19, Issue 37, September 13, 2023., 2023
Covalent organic frameworks (COFs) have desirable properties but their powder form hinders practical applications. This review focuses on magnetic COFs and their applications in wastewater treatment. The review highlights the structural parameters that impact adsorption performance, and discusses the challenges and future prospects in the field ...

A survey of Dinophysis spp. and their potential to cause diarrhetic shellfish poisoning in coastal waters of the United States

Journal of Phycology, Volume 59, Issue 4, Page 658-680, August 2023., 2023
Abstract Multiple species of the genus Dinophysis produce diarrhetic shellfish toxins (okadaic acid and Dinophysis toxins, OA/DTXs analogs) and/or pectenotoxins (PTXs). Only since 2008 have DSP events (illnesses and/or shellfish harvesting closures) become recognized as a threat to human health in the United States.

Safety of an ethanolic extract of the dried biomass of the microalga Phaeodactylum tricornutum as a novel food pursuant to Regulation (EU) 2015/2283

EFSA Journal, Volume 21, Issue 7, July 2023., 2023
Abstract Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on an ethanolic extract of the dried biomass of the microalga Phaeodactylum tricornutum as a novel food (NF) pursuant to Regulation (EU) 2015/2283.

Integrative monitoring strategy for marine and freshwater harmful algal blooms and toxins across the freshwater‐to‐marine continuum

Integrated Environmental Assessment and Management, Volume 19, Issue 3, Page 586-604, May 2023., 2023
Abstract Many coastal states throughout the USA have observed negative effects in marine and estuarine environments caused by cyanotoxins produced in inland waterbodies that were transported downstream or produced in the estuaries. Estuaries and other downstream receiving waters now face the dual risk of impacts from harmful algal blooms (HABs) that ...
