Gene Expression And Alzheimer's Disease: Evaluation Of Gene Expression Patterns In Brain And Blood For An Alzheimer's Disease Mouse Model, Amanda Hazy
Senior Honors Theses
Previous studies have established a causative role for altered gene expression in development of Alzheimer’s disease (AD). These changes can be affected by methylation and miRNA regulation. In this study, expression of miRNA known to change methylation status in AD was assessed by qPCR. Genome-wide expression changes were determined by RNA-sequencing of mRNA from hippocampus and blood of control and AD mice. The qPCR data showed significantly increased expression of Mir 17 in AD, and sequencing data revealed 230 genes in hippocampus, 58 genes in blood, and 8 overlapping genes showing significant differential expression (p value ≤ 0.05). Expression data …

Research has shown that changes in gene expression play a critical role in the development of Alzheimer’s Disease (AD). Our project will evaluate genome-wide RNA expression patterns from brain and blood in an AD mouse model. This analysis will provide insight regarding the mechanisms of AD pathology as well as determine a possible diagnostic tool utilizing RNA expression patterns found in the blood as biomarkers for AD.

Alzheimer’s disease (AD) is characterized by neurofibrillary tangles and extracellular amyloid-β plaques (Aβ). Despite ongoing research, some ambiguity remains surrounding the role of Aβ in the pathogenesis of this neurodegenerative disease. While several studies have focused on the mutations associated with AD, our understanding of the epigenetic contributions to the disease remains less clear. To that end, we determined the changes in DNA methylation in differentiated human neurons with and without Aβ treatment. We isolated the DNA from neurons treated with Aβ or vehicle, and digested the two samples with either a methylation-sensitive (HpaII) or a methylation-insensitive (MspI) restriction endonuclease. …
