3-nitropropionic acid (3-NP) is a mycotoxin widely used to produce a rat model of Huntington's disease. While there are numerous studies on the effect of this neurotoxin, still further investigation is required to understand the influence of this toxin on different regions of the brain. In the present study, there are two groups of rats of which one is treated with 3-NP. Behavioral, stereological and immunohistochemical analyses were conducted. The results show that locomotor activity is largely affected and anxiety is induced up to a certain level, but there is no gross manifestation of deficit in memory. Microscopic observations illustrate damages in the hippocampus and other parts of the brain. Astrogliosis and glial scars were another finding of this study. In conclusion, although 3-NP can be used as a model of Huntington's disease, it exerts a disseminated effect on different regions of the brain.

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.

Huntington's disease (HD) is a hereditary neurodegenerative disorder characterized by involuntary motor dysfunction and progressive cognitive impairment. This study aimed to explore the therapeutic potential of Coffea arabica (CA) phytoconstituents using a network pharmacology-based drug repurposing approach. CA-related Phytoconstituents were identified from public databases, while HD-related targets were retrieved from the DisGeNET database.

3-Nitropropionic acid (3-NP), a mycotoxin present in various plants and fungi, poses significant reproductive health risks to animals and humans through food chains contamination. This study aimed to explore the protective effects and mechanisms of silibinin, a bioactive flavonoid derived from the herbal plant Silybum marianum, against 3-NP-induced reproductive toxicity. Our findings demonstrated that silibinin treatment significantly alleviated 3-NP-induced ovarian follicular atresia and preserved ovarian histoarchitecture.

Here, we design triplex DNA-modified gold nanoparticles that respond to a tunable pH range. Homopyrimidine strand-modified gold nanoparticles and homopurine/homopyrimidine duplexes are utilized in the system. Upon acidification, the duplexes bind to gold nanoparticle-conjugated strands through Watson-Crick and Hoogsteen base pairing, forming triplex DNA with blunt ends on the nanoparticle.

Background: Huntington's disease (HD) is a fatal neurodegenerative disorder characterized by progressive motor decline and neuronal loss, with no curative disease-modifying therapies available. The mitochondrial toxin 3-nitropropionic acid (3-NP) is widely used to model HD-like pathologies. We investigated the therapeutic potential of coniferaldehyde (CFA), a natural phenolic compound with anti-inflammatory, antioxidant, and anti-radical properties, against 3-NP-induced neurodegeneration.
