Integrating network toxicology, transcriptomics, and metabolomics uncovers the hepatotoxic mechanisms of okadaic acid in LO2 cells

Ecotoxicology and Environmental Safety
Okadaic acid (OKA), a potent phycotoxin existed in shellfish, is known to cause liver damage. However, the hepatic mechanisms underlying its toxicity remain poorly understood.

Ocean acidification increases domoic acid contents during a spring to summer succession of coastal phytoplankton

, 2020
Enrichment of the oceans with CO2 may be beneficial for some marine phytoplankton, including harmful algae. Numerous laboratory experiments provided valuable insights into the effects of elevated pCO2 on the growth and physiology of harmful algal species,

Assessing the effects of phycotoxin mixtures on marine zooplankton : insights from copepod responses at different life stages

The expansion of human activities into oceans and lakes has profoundly disrupted aquatic ecosystems. Over recent decades, HAB occurrences have increased due to mounting anthropogenic pressures. Harmful algal blooms (HABs) are a phenomenon occurring hen

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.
