Identification and correlation of novel genes associated with progression of Alzheimer’s disease
Xia & He Publishing Inc.
Background and objectives
Alzheimer’s disease (AD), an enduring neurodegenerative malady, contributes significantly to dementia cases, with late-onset AD being more common than early-onset AD. Despite extensive research to diagnose and treat AD, the intricate protein network impedes the development of efficacious drugs or targets. This study endeavored to identify previously undiscovered genetic reservoirs associated with AD progression, which could be targeted as therapeutic markers.
Methods
Employing the robust tools of R-language, we dissected vast RNA sequence datasets comprising numerous samples and thousands of genes, pinpointing potential candidates implicated in AD’s trajectory. Thus, we selected the GSE203206 dataset, which includes AD patients and non-dementia controls, based on our criteria. After normalization, RNA-Seq data was compared, and log2fold change was calculated to determine the highly dysregulated genes. Further network analysis of genes and their associated miRNA was performed to determine a characteristic change in control and patient groups.
Results
Differential expression analysis revealed 13 dysregulated genes in AD, wherein 12 were upregulated, and one was down-regulated. Furthermore, we identified hsa-miR-30-5p as a significant miRNA associated with AD, aligning with previous studies and highlighting its high involvement.
Conclusions
This investigation has unveiled four novel genes and a paramount miRNA implicated in AD, thus furnishing potential targets for therapeutic interventions. These discoveries pave the way for further exploration into the intricate functions and implications of these genetic entities in AD.
