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: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are to compare Young and Old muscles transcriptome profiling (RNA-seq) to optimal high-throughput data analysis Results: Using an optimized data analysis workflow, we mapped about 30 million sequence reads per sample to the mouse genome (build mm10) and identified 24799 genes. Among them, 95.7% of the genes displayed the similar expression level in both young and old muscles.2% of genes (501) were significantly up-regulated and 2.3% of genes (584) were significantly down-regulated. p value <0.05.
Project description:Investigation of whole genome expression pattern of 60 and 72 hours post fertilization Danio Rerio embryos exposed to TMT and vehicle control Embryos were exposed to 10uM TMT or control from 48hpf to 60 or 72 hpf. Three replicates were collected for each time point. 40 embryos were pooled to comprise a replicate.
Project description:Proteomic analysis of young and old murine diaphragm and associated changed in contractile aproperties. Redox sensitive Cysteine residues from both adult and old diaphragm tissues examined.
Project description:Examination of the difference in mRNA expression profile between mid-old fibroblasts co-cultured with mid-old fibroblasts and mid-old fibroblasts co-cultured with young fibroblasts
Project description:Aging of the peripheral nervous system (PNS) is associated with structural and functional changes that lead to a reduction in regenerative capacity and the development of age-related peripheral neuropathy. Myelin is a central component in maintaining physiological peripheral nerve function, and differences in myelin maintenance, degradation, formation and clearance have been suggested to contribute to age-related PNS changes. In addition, recent proteomic studies have elucidated the complex composition of the total myelin proteome in health and its changes in neuropathy models. However, changes in the myelin proteome of peripheral nerves during ageing have not been investigated. Hence, the aim of this proteomics experiment was to define proteome changes in isolated myelin fractions during ageing, by investigating myelin proteome profiles from young (nerves from 2-3 month old mice) and old (nerves from 18 months old mice) nerves.
