Mechanism of the stimulatory action of okadaic acid on lipolysis in rat fat cells
Okadaic acid was found to induce concentration- and time-dependent lipolysis in rat fat cells in the absence of lipolytic hormones, but it did not significantly increase the total hormone-sensitive lipase (HSL) activity in these fat cells, the activity ...

Okadaic Acid Is a Potent Angiogenesis Inducer [PDF]
Okadaic acid, which is a non‐12‐0‐tetradecanoylphorbol‐13‐acetate (TPA)‐type tumor promoter and an inhibitor of protein phosphatases 1 and 2A, induced angiogenesis in the chorioallantoic membrane of the chick embryo. Its potent angiogenic activity was dose‐dependent. The minimum effective dose was 5 fmol/egg and the effective dose for 50% induction was

The insect, Galleria mellonella, is a compatible model for evaluating the toxicology of okadaic acid [PDF]
The polyether toxin, okadaic acid, causes diarrhetic shellfish poisoning in humans. Despite extensive research into its cellular targets using rodent models, we know little about its putative effect(s) on innate immunity.

Elastic tethers, connecting telomeres of all separating anaphase chromosome pairs, lose elasticity when they lengthen during anaphase. Treatment with phosphatase inhibitor CalyculinA causes anaphase chromosomes to move backwards after they reach the ...

This study examines various functional, biochemical, and structural changes in rat adrenocortical and ovarian granulosa cells that could account for the decline in lipoprotein-supported hormone production after cell treatment with the protein phosphatase

Risk Assessment of Pectenotoxins in New Zealand Bivalve Molluscan Shellfish, 2009–2019
Pectenotoxins (PTXs) are produced by Dinophysis spp., along with okadaic acid, dinophysistoxin 1, and dinophysistoxin 2. The okadaic acid group toxins cause diarrhetic shellfish poisoning (DSP), so are therefore regulated.

Modulation of macrophage scavenger receptor transport by protein phosphorylation
The identification of three highly conserved phosphorylation sites in the cytoplasmic domain of each of the monomeric subunits of the macrophage scavenger receptor suggests that protein phosphorylation may regulate this receptor pathway.

Lipophilic Toxins in Wild Bivalves from the Southern Gulf of California, Mexico
Most of the shellfish fisheries of Mexico occur in the Gulf of California. In this region, known for its high primary productivity, blooms of diatoms and dinoflagellates are common, occurring mainly during upwelling events.

Solid phase extraction for removal of matrix effects in lipophilic marine toxin analysis by liquid chromatography-tandem mass spectrometry [PDF]
The potential of solid phase extraction (SPE) clean-up has been assessed to reduce matrix effects (signal suppression or enhancement) in the liquid chromatography-tandem mass spectrometry (LC¿MS/MS) analysis of lipophilic marine toxins.
