Okadaic acid–induced apoptosis in malignant glioma cells [PDF]

open access: yesNeurosurgical Focus, 2003
Object Okadaic acid (OA), a potent protein phosphatase inhibitor, has been known to induce apoptosis in a variety of cell types. The authors attempted to characterize further this model by identifying proteins involved in this form of programmed cell death.

Machine Learning Integration Framework Constructs a Lactylation‐Associated Gene Signature to Improve Prognosis in Bladder Cancer

open access: yesCancer Medicine, Volume 15, Issue 1, January 2026.
ABSTRACT Background Bladder cancer remains a significant challenge in oncology owing to its high recurrence rates and limited treatment options, particularly in cases of resistance to standard therapies. Aims Our study aimed to pinpoint a lactylation‐associated gene signature capable of predicting prognosis and providing important theoretical support ...

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

open access: yesMarine 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.

Microcystins Alter Chemotactic Behavior in Caenorhabditis elegans by Selectively Targeting the AWA Sensory Neuron

open access: yesToxins, 2014
Harmful algal blooms expose humans and animals to microcystins (MCs) through contaminated drinking water. While hepatotoxicity following acute exposure to MCs is well documented, neurotoxicity after sub-lethal exposure is poorly understood. We developed

Exploring Autophagy Inducing Molecules: Targeting Diverse Pathways in Alzheimer's Disease Management

open access: yesMedicinal Research Reviews, Volume 46, Issue 1, Page 272-298, January 2026.
ABSTRACT Neurodegenerative disorders, including Alzheimer's disease (AD), impose a significant burden on society due to their progressive nature and the associated healthcare costs. Autophagy, a vital cellular degradation process, has emerged as a promising therapeutic target in these disorders.

The effects of immune challenge on phenoloxidase activity in locust salivary glands in vitro [PDF]

open access: yes, 2008
Homogenates of salivary glands from Locusta migratoria possess phenoloxidase (PO) activity. This study investigates the activation of prophenoloxidase (PPO) in these glands in vitro. When freshly dissected salivary glands from L. migratoria are incubated

Phospho‐Proteomics Identifies D‐Group MAP Kinases as Substrates of the Arabidopsis Tyrosine Phosphatase RLPH2

open access: yesPlant Direct, Volume 10, Issue 1, January 2026.
ABSTRACT Despite being one of the few bona fide plant tyrosine phosphatases, the Arabidopsis thaliana Rhizobiales‐like phosphatase 2 (RLPH2) has no known substrates. Utilizing phospho‐proteomics, we identified the activation loop phospho‐tyrosine of several A. thaliana D‐group mitogen‐activated protein kinases (MPKs) as potential RLPH2 substrates.

Diverse Bacterial PKS Sequences Derived From Okadaic Acid-Producing Dinoflagellates

open access: yesMarine Drugs, 2008
Okadaic acid (OA) and the related dinophysistoxins are isolated from dinoflagellates of the genus Prorocentrum and Dinophysis. Bacteria of the Roseobacter group have been associated with okadaic acid producing dinoflagellates and have been previously ...

Shape oscillations of human neutrophil leukocytes: characterization and relationship to cell motility [PDF]

open access: yes, 1996
When neutrophil leukocytes are stimulated by chemotactic factors or by substratum contact, they change their shape. Shape changes are a prerequisite for cellular migration and typically involve the extrusion of thin, veil-like lamellipods and the ...
