Resumen
3-Nitropropionic acid (3-NPA) is a deadly neurotoxic nitroalkane found in numerous fungi and leguminous plants. 3-NPA, known as an antimetabolite of succinate, irreversibly inhibits succinate dehydrogenase and disrupts mitochondrial oxidative phosphorylation. Its utility in modeling Huntington’s disease (HD) and oxidative stress has garnered significant research interest. Derivatives of 3-NPA, formed through esterification, have a wide range of biological activities including neurotoxic, antiviral, insecticidal, antimicrobial and antioxidant properties.

Resumen
AbstractThe morphologic and histochemical effects of 3‐nitropropionic acid (NPA) were examined in cultured murine embryonal carcinoma cells. NPA caused a dose‐dependent inhibition of cell proliferation of cultured murine embryonal carcinoma cells at concentrations above 1.05 mM and was lethal at 4.2 mM. Morphologic changes included gross swelling of the cells, swelling of mitochondria and accumulation of organellar debris within the cytoplasm. NPA inhibited the activity of succinate dehydrogenase but not of malate, isocitrate or glucose‐6‐phosphate dehydrogenases, resulting in a decrease in in

To address this hypothesis, the levels of dopamine (DA) and some oxidative stress biomarkers were measured after administration of 3-NPA. Young male Fischer rats were treated for three days with cerebrolysin, 3-NPA or both substances.

Data presented here demonstrate that immunophilin ligand, FK506 (10-130 µM), but not CsA (1-50 µM), or ryanodine receptor blocker, dantrolene (1-100 µM), enhances the formation of KYNA in cortical slices.

Resumen
Coconut water is a widely consumed natural beverage, prized for its hydration and health benefits. However, recent clinical evidence highlights a rare but life-threatening risk associated with its improper storage. This review centres on a fatal case involving a 69-year-old man in Denmark who developed acute neurotoxic symptoms such as nausea, vomiting, profuse sweating, and brain swelling after consuming coconut water left unrefrigerated for one month. Laboratory analysis confirmed contamination by the fungus <em>Arthrinium saccharicola</em>, which produces 3-nitropropionic acid (3-NPA), a mi

Resumen
The PA4203 gene encodes a LysR regulator and lies between theppgLgene (PA4204), which encodes a periplasmic gluconolactonase, and, in the opposite orientation, the PA4202 (nmoA) gene, coding for a nitronate monooxygenase, andddlA(PA4201), encoding ad-alanine alanine ligase. The intergenic regions between PA4203 andppgLand between PA4203 andnmoAare very short (79 and 107 nucleotides, respectively). Here we show that PA4203 (nmoR) represses its own transcription and the expression ofnmoA. A chromatin immunoprecipitation analysis showed the presence of a single NmoR binding site betweennmoAandnmo

Resumen
Mycotoxins are key risk factors in human food and animal feed. Most of food-origin mycotoxins could easily enter the organism and evoke systemic toxic effects, such as aflatoxin B1 (AFB1), ochratoxin A (OTA), T-2 toxin, deoxynivalenol (DON), zearalenone (ZEN), fumonisin B1 (FB1), and 3-nitropropionic acid (3-NPA). For the last decade, the researches have provided much evidences in vivo and in vitro that the brain is an important target organ on mycotoxin-mediated neurotoxic phenomenon and neurodegenerative diseases. As is known to all, glial cells are the best regulator and defender of neurons

Resumen
Abstract The secondary metabolite 3-nitropropionic acid (3-NPA) is produced by certain fungi. The metabolite is a potent toxin which inhibits the citric acid cycle. A medical case from 2021 described a 69-year-old Danish man who ingested 3-nitropropionic acid contaminated coconut water. The man died 26 hours after ingestion. Subsequent analysis identified Apiospora saccharicola as the fungi responsible for synthesising 3-NPA in the coconut. The metabolic pathway for 3-NPA is unknown but is thought to be activated by adverse growth conditions. This study aimed to confirm that Apiospora can prod

The mechanism of action by which oxidative stress induces granulosa cell apoptosis, which plays a vital role in initiating follicular atresia, is not well understood. In the present study, the effect of 3-nitropropionic acid (3-NPA) on oxidative stress and apoptosis in granulosa cells in geese was investigated. Our results showed that treatment with 3-NPA at 5.0 mmol/l for 24 h increased intracellular reactive oxygen species (ROS) production by 25.4% and decreased granulosa cell viability by 45.5% (P&lt;0.05).

AbstractAbnormal apoptosis of ovarian cells caused by oxidative stress is an important cause of premature ovarian failure (POF).

However, the protective effect and mechanism of PCs on ovarian function during the course of POF remain unknown. In this study, female mice were injected with 3-nitropropionic acid (3-NPA) to establish an ovarian oxidative stress model; at the same time, the mice were treated with PC via gavage.
