Outline of Final Research Achievements |
Alzheimer's disease (AD) is one of the major causes of dementia. In addition to APOE4, non-genetic risk factors such as diabetes have also emerged. However, mechanisms by which diabetes increases AD have not been fully understood. To investigate the interactions between AD and diabetes, we generated a novel model with AD and diabetes by crossing amyloid precursor protein (APP) mice and ob/ob mice. These mice show cognitive dysfunction even in young age. We performed gene expression analysis of APP+ob/ob mice. There are genes upregulated only in APP+ob/ob mice. These genes include 37 genes such as Factor X1, a secreted protein, and Factor X2, a transcriptional factor. We are generating gene knockout mice from the genes with the highest changes. Using these knockout mice, we will assess whether these genes could be targets for novel therapeutics for dementia.
