Project description: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.

Project description:The goal of the experiment was to understand the role of IL-18 in Alzheimers disease. Gene expression was examined in the hippocampus of wild type mice and the APP/PS1 mice (which are a mouse model for Alzheimers disease) that either encoded IL-18 or had the IL-18 gene knocked out.

Project description:In order to disclose the mechanisms, a high-throughput quantitative proteomics analysis was established to investigate the proteome profiles changes of hippocampus and temporal lobe of WT mice, APP/PS1 mice and rapamycin treated APP/PS1 mice.The extraction of proteins of hippocampus and temporal tissue employed liquid nitrogen grounding method, which was described as previous works of our laboratory and other laboratories [20, 21]. After fully and immediately grinding under the protection of liquid nitrogen, the products was dissolved by lysis buffer (8 M urea and 1 cocktail in PBS, pH = 8.0) prepared in ice ahead of schedule and then the solutions were transferred to a 1.5-mL tube in ice. Cellular debris was removed by centrifugation (12,000 rpm, 15 min, 4 °C) and the liquid supernatant was transferred into a fresh 1.5-mL tube and immediately stored at -80 °C. The protein concentration of the supernatant was detected by Nanodrop 2000 (Thermo Scientific, NJ, USA) following the manufacture instructions.

Project description:With the criterion of 2-fold cutoff, 7 miRNAs were upregulated and 7 miRNAs were downregulated in APP/PS1 hippocampal tissues compared with WT hippocampal tissues Microarray analysis of miRNAs was performed on pooled hippocampal tissues from WT (n=16) and APP/PS1 mice (n=16) at E14

Project description:To examine the regulation of microglia by N-AS-triggered SPMs, we analyzed the gene expression patterns of microglia derived from WT, APP/PS1, and N-AS-injected APP/PS1 mice using RNAseq. These results indicated that N-AS-triggered SPMs activated an anti-inflammatory, positive immune response, and enhanced the phagocytic abilities of microglia in N-AS-treated APP/PS1 mice, leading to resolution of neuroinflammation and upregulation of phagocytic microglia in this AD animal model.

Project description:RNA samples from the cerebral cortex of APP/PS1 and WT mouse littermates aged 3, 6 and 12 months were analyzed using the Affymetrix Genechip Mouse Gene 1.1 ST Array. The APP-PS1 transgenic mouse express the human mutated forms APPswe and PS1dE9. This is a good model of familial Alzheimer Disease because it reproduces several features of the disease as β-amyloid deposits throughout the brain and exhibit memory impairment by the end of the sixth month and is a simple model to study the molecular pathways. The aim of this study is to identify dysregulation of inflammation pathways in order to understand shifts of inflammation responses with disease progression.
