摘要:

亨廷顿舞蹈症(HD)是一种极其有害的常染色体遗传性神经退行性疾病。运动功能障碍、精神障碍和认知缺陷是该病的特征。当前的研究检查了 6-姜烯酚是否对 3-硝基丙酸 (3-NPA) 诱导的大鼠 HD 具有保护作用。总共 30 只雄性 Wistar 大鼠接受了 6-姜烯酚(每次口服 10 和 20 毫克/千克)注射 3-NPA(10 mg/kg i.p.)前一小时,持续 15 天。进行了行为测试,包括窄梁行走、旋转杆测试和握力测试。评估了促进氧化应激的生化测试[超氧化物歧化酶(SOD)、还原型谷胱甘肽(GSH)、过氧化氢酶(CAT)和丙二醛(MDA)],包括神经递质血清素(5-HT)、多巴胺(DA)、去甲肾上腺素(NE)的变化)、高香草酸 (HVA)、(3,4-二羟基苯乙酸 (DOPAC)、γ-氨基丁酸 (GABA) 和 5-羟基吲哚乙酸 (5-HIAA)、核因子 kappa-B (NF-κB) 、肿瘤坏死因子-α (TNF-α)、白细胞介素-1β (IL-1β)、IL-6、脑源性神经营养因子 (BDNF) 和核因子红细胞 2 相关因子 2 (Nrf2)。使用 AutoDock 工具将 shogaol 对接至 TNF-α (2AZ5)、NF-κB (1SVC)、BDNF) [1B8M] 和 Nrf2 [5FZN] 蛋白的活性位点。与 3 组相比,6-shogaol 组显着改善了行为活动-注射NPA的对照大鼠。此外,3-NPA 诱导的神经递质、生化和神经炎症指数显着改变,而 6-shogaol 可以有效逆转这种变化。 6-姜烯酚在 -9.271 (BDNF) kcal/mol 处表现出有利的负结合能。本研究证明了 6-姜烯酚在实验动物范例中对 3-NPA 诱导的大鼠 HD 的神经保护作用。尽管还需要更多的研究来明确证实,但所提出的机制得到了免疫组织化学分析和蛋白质印迹的支持。版权所有:© 2024 Jambi 等人。这是一篇根据知识共享署名许可条款分发的开放获取文章,允许在任何媒体上不受限制地使用、分发和复制,前提是注明原始作者和来源。
Huntington's disease (HD) is an extremely harmful autosomal inherited neurodegenerative disease. Motor dysfunction, mental disorder, and cognitive deficits are the characteristic features of this disease. The current study examined whether 6-shogaol has a protective effect against 3-Nitropropionic Acid (3-NPA)-induced HD in rats.A total of thirty male Wistar rats received 6-shogaol (10 and 20 mg/kg, per oral) an hour before injection of 3-NPA (10 mg/kg i.p.) for 15 days. Behavioral tests were performed, including narrow beam walk, rotarod test, and grip strength test. Biochemical tests promoting oxidative stress were evaluated [superoxide dismutase (SOD), reduced glutathione (GSH), catalase (CAT) and malondialdehyde (MDA)], including changes to neurotransmitters serotonin (5-HT), dopamine (DA), norepinephrine (NE), homovanillic acid (HVA), (3,4-dihydroxyphenylacetic acid (DOPAC), γ-aminobutyric acid (GABA), and 5-hydroxy indole acetic acid (5-HIAA), nuclear factor kappa-B (NF-κB), tumor necrosis factor-α (TNF-α), interleukins-1β (IL-1β), IL-6, brain-derived neurotrophic factor (BDNF), and nuclear factor erythroid 2-related factor 2 (Nrf2). The 6-shogaol was docked to the active site of TNF-α (2AZ5), NF-κB (1SVC), BDNF) [1B8M], and Nrf2 [5FZN] proteins using AutoDock tools.The 6-shogaol group significantly improved behavioral activity over the 3-NPA-injected control rats. Moreover, 3-NPA-induced significantly altered neurotransmitters, biochemical and neuroinflammatory indices, which could efficiently be reversed by 6-shogaol. The 6-shogaol showed favorable negative binding energies at -9.271 (BDNF) kcal/mol.The present investigation demonstrated the neuroprotective effects of 6-shogaol in an experimental animal paradigm against 3-NPA-induced HD in rats. The suggested mechanism is supported by immunohistochemical analysis and western blots, although more research is necessary for definite confirmation.Copyright: © 2024 Jambi et al.
