Experimental Basis for the High Oral Toxicity of Dinophysistoxin 1: A Comparative Study of DSP

Toxins, 2014
Okadaic acid (OA) and its analogues, dinophysistoxin 1 (DTX1) and dinophysistoxin 2 (DTX2), are lipophilic and heat-stable marine toxins produced by dinoflagellates, which can accumulate in filter-feeding bivalves.

Systemic inflammation suppresses spinal respiratory motor plasticity via mechanisms that require serine/threonine protein phosphatase activity

Journal of Neuroinflammation, 2021
Background Inflammation undermines multiple forms of neuroplasticity. Although inflammation and its influence on plasticity in multiple neural systems has been extensively studied, its effects on plasticity of neural networks controlling vital life ...

Detachment‐Induced FAK‐STAT3‐NNMT Inhibits CTCs Anoikis to Promote Breast Cancer Metastasis by Enhancing Fatty Acid Oxidation

Advanced Science, Volume 13, Issue 29, 22 May 2026.
The FAK‐STAT3‐NNMT axis drives anoikis resistance in circulating tumor cells by reprogramming fatty acid oxidation. Targeting this metabolic vulnerability suppresses metastasis, untangling a key mechanism of breast cancer progression and revealing NNMT as a promising therapeutic target.

Isolation and identification of a cis-C₈-diol-ester of okadaic acid from Dinophysis acuta in New Zealand [PDF]

, 2006
A cis-isomer of a C8-diol ester of okadaic acid (1) was isolated during large-scale purification of pectenotoxins (PTXs) from extracts of Dinophysis acuta collected from the west coast of South Island, New Zealand.

Identification of 19-epi-okadaic Acid, a New Diarrhetic Shellfish Poisoning Toxin, by Liquid Chromatography with Mass Spectrometry Detection

Marine Drugs, 2008
Okadaic acid (1) (OA) and its congeners are mainly responsible for diarrhetic shellfish poisoning (DSP) syndrome. The presence of several OA derivatives have already been confirmed in Prorocentrum and Dinophysis spp.

Nuclear Mechanotransduction Across the Metastatic Cascade: Decoding Spatiotemporal Heterogeneity in Cancer Dissemination

Advanced Science, Volume 13, Issue 25, 4 May 2026.
Tumor metastasis results from complex interactions between cancer cells and mechanical microenvironments. We propose a “nucleus‐centered, cross‐stage mechanical signal decoding” model, highlighting how nuclear mechanosensors interpret forces at different stages.

Isolation and Characterization of Okadaic Acid Binding Proteins from the Marine Sponge Halichondria okadai^† [PDF]

, 2016
Okadaic acid, first isolated from the marine sponge Halichondria okadai, is a potent inhibitor of protein phosphatases 1 and 2A (PP1 and PP2A, respectively).

Activation of the Tumor Suppressor PP2A Emerges as a Potential Therapeutic Strategy for Treating Prostate Cancer

Marine Drugs, 2015
Protein phosphatase 2A (PP2A) is a tumor suppressor complex that has recently been reported as a novel and highly relevant molecular target in prostate cancer (PCa). However, its potential therapeutic value remains to be fully clarified.

Enteric Nervous System Damage by Food Contaminants: A Pathway to Neurodegeneration?

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT The enteric nervous system (ENS), a key component of the gut–brain axis, has emerged as a critical player in the pathogenesis of Parkinson's disease (PD). It is the first neural system exposed to food contaminants (FCs)—a diverse group of ubiquitous toxic compounds fortuitously present in food derived from production, processing, storage, or ...

Acute inhibition of insulin-stimulated glucose transport by the phosphatase inhibitor, okadaic acid [PDF]

, 2008
Insulin is thought to exert its effects on cellular function through the phosphorylation or dephosphorylation of specific regulatory substrates. We have analyzed the effects of okadaic acid, a potent inhibitor of type 1 and 2A protein phosphatases, on ...
