Meanwhile, the expression of the nine DEGs in the hippocampi of AD and WT mice were also measured, and the results showed that the expression levels of all DEGs decreased in the hippocampi of AD mice compared to those in their control littermates (RPL23: p = 0.0034; ACTG1: p = 0.0021; DDX5: p < 0.0010; RPS6KB2: p < 0.0010; ALDOA: p = 0.0086; NOL6: p < 0.0010; EFHD2: p < 0.0010; HERPUD1: p < 0.0010; PRRT1: p < 0.0010; Figure 5b). This evidence concerns the gene ACTG1 and Alzheimer disease.
