Parkinson's disease (PD), the most prevalent type of Parkinsonism, is a progressive neurological condition characterized by a range of motor and non-motor symptoms. The complicated etiology of PD is thought to involve a summation of aging, genetic predisposition, and environmental variables. However, the α-synuclein protein plays a significant role in the disease's pathophysiology.
The UAS-α-Syn and Ddc-Gal4 strains were crossed to produce offspring referred to as PD flies. The entire population of flies was divided into five groups, each having about 100 flies and five replicates. The control group (w) and the PD group not receiving treatment were exposed to lauric acid (LA)/levodopa (LD)-free diet, while the PD groups that received treatments were fed with either a 250 mg/kg LA diet, a 250 mg/kg LD diet, or a combination of the two for 21 days. Longevity, geotaxis, and olfactory assays were performed in addition to other biochemical tests.
As a result of the overexpression of α-synuclein, the locomotive capacity, lifespan, and antioxidant status were all significantly (p < .05) reduced, and the apoptotic and neuroinflammatory activities were increased. Nevertheless, the majority of the treated flies improved significantly (p < .05).
LA, whether combined with LD or not, elicited a significant response in α-synuclein/dopa decarboxylase genetically modified Drosophila melanogaster Parkinsonism models.
帕金森病(PD)是最常见的帕金森综合征类型,是一种进行性神经疾病,其特征是一系列运动和非运动症状。PD 的复杂病因被认为涉及衰老、遗传易感性和环境变量的综合作用。然而,α-突触核蛋白在疾病的病理生理学中起着重要作用。
UAS-α-Syn 和 Ddc-Gal4 品系杂交产生了被称为 PD 果蝇的后代。将所有的果蝇分为五组,每组约有 100 只果蝇和 5 个重复。对照组(w)和未接受治疗的 PD 组暴露于不含月桂酸(LA)/左旋多巴(LD)的饮食中,而接受治疗的 PD 组则分别喂食 250 mg/kg LA 饮食、250 mg/kg LD 饮食或两者的组合 21 天。除了其他生化测试外,还进行了寿命、趋地性和嗅觉测试。
由于α-突触核蛋白的过表达,运动能力、寿命和抗氧化状态均显著降低(p <.05),而凋亡和神经炎症活性增加。然而,大多数接受治疗的果蝇显著改善(p <.05)。
LA 无论是否与 LD 联合使用,均能引起α-突触核蛋白/多巴胺脱羧酶基因修饰的黑腹果蝇帕金森病模型产生显著反应。
