Interestingly, rescued genes upregulated in both cortex and hippocampus included genes related to DS and Alzheimer disease, such as App (Tosh et al., 2021), Ets2 (Helguera et al., 2005), Bace2 (Alić et al., 2021), and Olig2 (Choong et al., 2015). This evidence concerns the gene OLIG2 and Alzheimer disease.
