Project description:Minimal processing using chlorinated water washes is a common practice in the fresh produce industry to reduce the microbial load and bacterial pathogens attached on produce surfaces. To evaluate if E. coli O157:H7 strains with different phyllogenetic backgrounds are equally sensitive or display variable resistance to chlorine treatment, we studied the expression profile of Sakai and one 2006 spinach outbreak strain (TW 14359) in response to chlorine and hydrogen peroxide treatment.

Experiment Overall Design: 2 E. coli O157 strains are incubated with or without chlorine or H2O2 for 30 min for RNA extraction and hybridization on Affymetrix microarrays. We sought to compare the expression profile between the 2 strains with or without oxidative stress.
Project description:The transcriptomic response of Jurkat T lymphoma cells to hydrogen peroxide was investigated to determine the global effects of hydrogen peroxide on cellular gene expression.
Project description:Transcriptional profiling of GO-treated (24h) differentiating equine satellite cells (3rd day of differentiation) exposed to hydrogen peroxide (1h; last hour of pre-incubation with GO) compared to control GO-untreated cells. Goal was to determine the effects of GO pre-incubation on miRNA expression in equine satellite cells exposed to hydrogen peroxide.
Project description:Transcriptional profiling of HMB-treated (24h) differentiating equine satellite cells (3rd day of differentiation) exposed to hydrogen peroxide (1h; last hour of pre-incubation with HMB) compared to control HMB-untreated cells. Goal was to determine the effects of HMB pre-incubation on miRNA expression in equine satellite cells exposed to hydrogen peroxide.
