| Title |
Characterization of the chromatin accessibility in an Alzheimer’s disease (AD) mouse model (RNA-Seq) |
| Organism |
Mus musculus |
| Experiment type |
Expression profiling by high throughput sequencing
|
| Summary |
The assay for transposase-accessible chromatin by sequencing (ATAC-seq) was used to investigate the AD-associated chromatin reshaping in the APPswe/PS1dE9 (APP/PS1) mouse model. ATAC-seq data in the hippocampus of 8-month-old APP/PS1 mice were generated, and the relationship between chromatin accessibility and gene expression was analyzed in combination with RNA-sequencing.We identified 1690 increased AD-associated chromatin accessible regions in the hippocampal tissues of APP/PS1 mice and 1003 decreased chromatin accessible regions were considered to be related with declined AD-associated biological processes.In the APP/PS1 hippocampus, 1090 genes were found to be up-regulated and 1081 down-regulated. Interestingly, enhanced ATAC-seq signal was found in approximately 740 genes, with 43 exhibiting up-regulated mRNA levels.Our study reveals that alterations in chromatin accessibility may be an initial mechanism in AD pathogenesis.

| Overall design |
Hippocampal mRNA profiles of 8-month old wild type(WT) and APPswe/PS1dE9(APP/PS1) double transgenic mice were generated by deep sequencing, in triplicate,using Illumina Hiseq 150PE.
