The metabolism of ceramides is deregulated in the brain of Alzheimer’s disease (AD) patients and is associated with apolipoprotein (APO) APOE4 and amyloid-β pathology. However, how the ceramide metabolism changes over time in AD, in vivo, remains unknown. Distribution and metabolism of [18F]F-HPA-12, a radio-fluorinated version of the ceramide analog N-(3-hydroxy-1-hydroxymethyl-3-phenylpropyl) dodecanamide, was investigated in the brain of AD transgenic mouse models (FAD) on an APOE4 or APOE3 genetic background, by positron emission tomography and by gamma counter. We found that FAD mice displayed a higher uptake of [18F]F-HPA-12 in the brain, independently from the APOE4 …
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 …
