Aim:This study aims to investigate the molecular mechanisms underlying Alzheimer’s
disease (AD) by analyzing differentially expressed miRNAs and their target proteins to identify
key regulatory networks and therapeutic targets.Background:Alzheimer’s disease (AD) is a complex neurodegenerative disorder with multifaceted
regulatory mechanisms involving differentially expressed miRNAs. Recent studies suggest that
understanding the target proteins of these miRNAs may reveal crucial insights into AD pathology.Objective:The objective of this study was to investigate the role of differentially expressed miRNAs
in Alzheimer’s disease (AD) by identifying their target proteins and exploring the associated
regulatory networks. This includes uncovering key hub proteins and their involvement in critical
biological pathways linked to AD progression. Additionally, the study aims to identify transcription
factors regulating these proteins and evaluate potential therapeutic compounds targeting these
molecular players. By integrating these findings, the research seeks to provide a deeper understanding
of AD pathogenesis and pave the way for novel therapeutic strategies to mitigate its progression.Methods and Materials:Differentially expressed miRNAs were collected from reviews, with target
proteins identified using MiRDB, STRING, and Cytoscape. Promoter and transcription factor
(TF) analyses were performed using Enrichr, and potential therapeutic compounds targeting hub
proteins were explored via DrugBank.Results:This study identifies key hub proteins, including TNF, PTEN, KRAS, ESR1, H3-3B,
COL25A1, COL19A1, COL13A1, COL27A1, COL5A3, CCND1, FGF2, SMAD2, and PXDN, exploring
their roles in AD progression. GO and KEGG pathway analyses revealed that hub proteins,
including TNF, PTEN, KRAS, and ESR1, are involved in essential biological processes related
to neural differentiation and signaling. Cytocluster analysis identified clusters with significant
associations with AD, indicating complex interaction networks among these proteins.Discussion:Potential therapeutic agents, including TNF inhibitors, estrogen receptor agonists,
and KRAS inhibitors, were identified. Promoter and TF analysis further highlighted regulatory factors
in AD pathways.Conclusion:This study emphasizes crucial AD-related proteins and pathways, providing insights
for future therapeutic targeting of gene expression to mitigate AD progression
