阿尔茨海默病 (Alzheimer’s disease, AD) 是一种以进行性认知功能障碍和行为损害为特征的神经退行性疾病。 其病理特征包括β淀粉样蛋白(amyloid β-protein,Aβ)沉积形成的老年斑、微管相关蛋白(tubulin associated unit,tau)过度磷酸化导致的神经原纤维缠结(neurofibrillary tangles,NFTs),以及大脑皮层和海马等关键脑区神经元、突触的大量丧失,最终临床上表现为记忆减退、语言障碍及空间定向能力下降等症状,严重影响患者的生活质量。随着中国人口老龄化进程的加速,AD的发病率持续上升,已发展成为严重的公共卫生事件,迫切需要开发有效的治疗手段。近年来研究发现,Notch信号通路作为一种高度进化保守的途径,在细胞增殖、分化、发育以及凋亡等多种生物过程中发挥重要作用,其失调在AD的发病机制中起关键作用。此外,Notch信号通路与非编码RNA(non-coding RNA,ncRNA)的相互作用产生广泛的生物学效应,在多种疾病中被广泛报道。然而,在AD中对Notch信号通路与ncRNA的探讨相对缺乏。因此,本文基于生物信息学分析手段,整合多个公开数据库数据,系统筛选在AD中显著异常的Notch通路关键基因及其相关ncRNA,构建lncRNA-miRNA-mRNA调控网络,深入探讨其在AD发病过程中的内在联系及潜在机制,进一步评估这些分子作为AD早期诊断生物标志物及治疗干预靶点的可行性和应用价值,以期为AD的诊断和治疗提供新的策略。
Alzheimer’s disease (AD) is a chronic, progressive, and irreversible neurodegenerative disorder that typically begins with a subtle onset and progresses slowly. Pathologically, it is characterized by two hallmark features: the extracellular accumulation of amyloid β-protein (Aβ), forming senile plaques, and the intracellular hyperphosphorylation of tau protein, resulting in neurofibrillary tangles (NFTs). These pathological changes are accompanied by substantial neuronal and synaptic loss, particularly in critical brain regions such as the cerebral cortex and hippocampus. Clinically, AD presents as a gradual decline in memory, language abilities, and spatial orientation, significantly impairing the quality of life of affected individuals. With the aging population steadily increasing in China, the incidence of AD is rising, making it a major public health concern that requires urgent attention. The growing societal and economic burden of AD underscores the pressing need to identify effective diagnostic biomarkers and develop novel therapeutic strategies. Among the various molecular signaling pathways involved in neurological disorders, the Notch signaling pathway is especially noteworthy due to its evolutionary conservation and regulatory roles in cell proliferation, differentiation, development, and apoptosis. In the central nervous system, Notch signaling is essential for neurodevelopment and synaptic plasticity and has been implicated in several neurodegenerative processes. Although some studies suggest that Notch signaling may influence AD-related pathology, its precise role in AD remains poorly understood. In particular, the interaction between Notch signaling and non-coding RNAs (ncRNAs)—key regulators of gene expression—has received limited attention. NcRNAs, including long non-coding RNAs (lncRNAs) and microRNAs (miRNAs), are known to exert extensive regulatory functions at both transcriptional and post-transcriptional levels. Dysregulation of these molecules has been widely associated with various diseases, including cancers, cardiovascular conditions, and neurodegenerative disorders. Notably, interactions between ncRNAs and major signaling pathways such as Notch can produce widespread biological effects. While such interactions have been increasingly reported in several disease models, comprehensive studies investigating the regulatory relationship between Notch signaling and ncRNAs in the context of AD remain scarce. Given the capacity of ncRNAs to modulate signaling cascades and form complex regulatory networks, a deeper understanding of their crosstalk with the Notch pathway could provide novel insights into AD pathogenesis and reveal potential targets for diagnosis and treatment. In this study, we investigated the regulatory landscape involving the Notch signaling pathway and associated ncRNAs in AD using bioinformatics approaches. By integrating data from multiple public databases, we systematically identified significantly dysregulated Notch pathway-related genes and their interacting ncRNAs in AD. Based on this analysis, we constructed a lncRNA-miRNA-mRNA regulatory network to elucidate the potential mechanisms linking Notch signaling to ncRNA-mediated gene regulation in AD pathogenesis. Furthermore, we explored the internal relationships and molecular mechanisms within this network and assessed the feasibility and clinical relevance of these molecules as early diagnostic biomarkers and potential therapeutic targets for AD. This study aims to deepen our understanding of the molecular basis of AD and offer novel strategies for its diagnosis and treatment.
