Okadaic acid, a phosphatase inhibitor, decreases macrophage motility

open access: yes, 1991
Cellular locomotion results from a series of spatially and temporally integrated reactions. The coordinated regulation of these reactions requires sensitive intracellular signaling mechanisms.

Minisatellite Instability Induced by Okadaic Acid.

open access: yesTHE JOURNAL OF THE STOMATOLOGICAL SOCIETY,JAPAN, 1997
Okadaic acid (OA) is an inhibitor of serine/threonine protein phosphatase (PP) and a tumor promoter in mouse skin carcinogenesis. According to Carcinogenesis Division, National Cancer Center Research Institute, OA induces various genetic alterations, such as loss of exogenous genes, sister chromatid exchanges and diphtheria toxin resistant mutants ...

Microcystin-LR and okadaic acid-induced cellular effects: a dualistic response [PDF]

open access: yes, 2004
Microcystins, potent heptapeptide hepatotoxins produced by certain bloom-forming cyanobacteria, are strong protein phosphatase inhibitors. They covalently bind the serine/threonine protein phosphatases 1 and 2A (PP1 and PP2A), thereby influencing ...

Detection of diarrheal shellfish toxins

open access: yesReviews in Analytical Chemistry, 2022
Seafood poisoning outbreaks are often caused by biotoxins generated by harmful algal blooms. Shellfish toxins, mainly derived from phytoplankton, cause diarrhea and poisoning in humans who consume contaminated seafood. Many studies suggest that diarrheal

Catecholaminergic polymorphic ventricular tachycardia–linked ryanodine receptor variants exhibit domain‐specific calcium leak and calmodulin affinity properties

open access: yesThe Journal of Physiology, Volume 604, Issue 16, Page 6752-6770, 15 August 2026.
Abstract figure legend Catecholaminergic polymorphic ventricular tachycardia (CPVT) variants in N terminal (NTD) and central domain (CD) but not pore domain induce a pathological RyR2 conformational shift upon protein kinase A (PKA) phosphorylation, similar to that seen in heart failure (HF), calcium/calmodulin‐dependent protein kinase II (CaMKII ...

Cross-Reactivity of Ciguatoxin, Okadaic Acid, and Okadaic Acid Segments C with Monoclonal Antibodies to Ciguatoxin and Okadaic Acid

open access: yes, 2014
Recently, there has been increasing interest in certain low dalton marine toxins, as they have been implicated in seafood poisonings. The toxins include ciguatoxin (CTX), which is implicated in ciguatera fish poisoning, and okadaic acid (OA), which is ...

Use of Okadaic Acid to Identify Relevant Phosphoepitopes in Pathology: A Focus on Neurodegeneration

open access: yesMarine Drugs, 2013
Protein phosphorylation is involved in the regulation of a wide variety of physiological processes and is the result of a balance between protein kinase and phosphatase activities. Biologically active marine derived compounds have been shown to represent

Elimination of tau tangles and soluble aggregates with the small molecule ACI‐16664 prevents neurodegeneration in vivo

open access: yesAlzheimer's &Dementia, Volume 22, Issue 7, July 2026.
Abstract INTRODUCTION Pathological tau aggregates are key therapeutic targets in Alzheimer's disease (AD), but current approaches face limitations including poor intracellular penetration, lack of selectivity for aggregated over physiological tau, or reliance on invasive administration.

Okadaic acid inhibits amylase exocytosis from parotid acini stimulated by cyclic AMP [PDF]

open access: yes, 1991
To evaluate the role of protein phosphorylation in amylase exocytosis, we studied the effects of okadaic acid, a potent inhibitor of protein phosphatase types I and 2A, on amylase release and protein phosphorylation in rat parotid acini. Although okadaic
