Project description:We investigate if the differences in phenotype and transcriptome over age might be explained by an underlying change on the epigenetic level. We performed single-cell ATAC sequencing using the 10x Chromium platform. We profiled 2259 nuclei prepared from 3 young liver tissues and 2490 nuclei from 3 old liver tissues.

Project description:Mass spectrometry was performed with an Orbitrap Fusion Tribrid mass spectrometer (Thermo Scientific) interfaced with an UltiMate 3000 Binary RSLCnano System (Dionex). Proteome Discoverer v.1.4 (Thermo Scientific) with SEQUEST HT search engines was used for the spectra-preprocessing and HCD MS2 spectra were used for peptide identification and quantitation based on TMT reporter ions. TMT isobaric comparison of old versus young haematopoietic stem and progenitor cells. Young 1 and Young 2 are samples 126 and 128 of dataset UTH_1. Old 1 and Old 2 are samples 129 and 130 of UTH_1. Young 3 is sample 131 and Old 3 is sample 130 of dataset UTH_4.
Project description:Purpose: We used RNA-seq to compare daily rhythms of gene expression in livers of young and old mice. Methods: Livers of young and old mice were processed for RNA-seq at 4-h interval across 2 days. Gene expression level was analyzed by hisat2 and StringTie. Results: We obtained ~10 million high quality sequencing reads per time point per sample after quality control and alignment. Gene expression levels of ~19,000 transcripts were obtained for both age groups. We found genome-wide differenes in gene expression level as well as rhythms in gene expression. Conclusions: Our study revealed genomwide differences in the level and rhythm of liver gene expression between young and old mice.
