Project description:Human iPSCs and NSCs were engineered by AAVS1 and/or C13 safe-harbor TALENs which mediated targeted integration of various reporter genes at single or dual safe-harbor loci. Multiple clones of targeted human iPSCs were used to compare with parental untargeted NCRM5 iPSCs. Polyclonal targeted human NSCs were used to compare with their parental untargeted NCRM1NSCs or H9NSCs. Total RNA obtained from targeted human iPSCs or NSCs compared to untargeted control iPSCs or NSCs.
Project description:To evoke further attention to the potential hazard of increasingly accumulative blue light exposure, we construct a series of in vivo Drosophila models employed for multi-omics analyses. This project includes the identification results of untargeted metabolome quantification by LC-MS/MS and the Input and m6A IP data of MeRIP-seq of w1118 male adult whole flies.
Project description:Colon cancer onset and progression is strongly associated with the presence, absence, or relative abundances of certain microbial taxa in the gastrointestinal tract. However, specific mechanisms affecting disease susceptibility related to complex bacterial mixtures are poorly understood. We used a multi-omics approach to determine how differences in the complex gut microbiome (GM) influence the metabolome and host transcriptome and ultimately affect susceptibility to adenoma development. Fecal samples collected from Pirc rats harboring two distinct complex GMs were analyzed using ultra-high performance liquid chromatography mass spectrometry (UHPLC-MS). We identified putative metabolite profiles that predicted future disease severity from samples collected prior to observable disease onset. Transcriptome analyses performed after disease onset on normal epithelium and tumor tissues suggests that the GM also alters the host transcriptome. Integrated pathway (IP) analyses of the metabolome and transcriptome based on putatively identified metabolic features indicate that bile acid biosynthesis was enriched in rats with high tumors (GM:F344) along with increased fatty acid metabolism and mucin biosynthesis. These data emphasize the utility of using untargeted metabolomics to identify metabolites for revealing signatures of susceptibility and resistance.

Project description:Streptococcus agalactia were isolated from virginal swabs and from bovine. the experiment aims at differentiating the proteome and metabolome differences between the 2 isolated strains. To achieve this target, label free proteomics and untargeted metabolomics profiling were applied
Project description:This study focuses on the untargeted comparative metabolomics analysis of the endo-metabolome of both WT and acot-15 mutant C. elegans worms. Hydroxylamine was used to treat certain samples to capture the reactive electrophilic metabolites.
