Title Late Multiple Organ Surge in Interferon-regulated Target Genes Characterizes Staphylococcal Enterotoxin B Lethality
Organism Mus musculus
Experiment type Expression profiling by array
Summary Bacterial superantigens are virulence factors that cause toxic shock syndrome. Here, the genome-wide, temporal response of mice to lethal intranasal staphylococcal enterotoxin B (SEB) was investigated in six tissues (PBMC, lung, spleen, kidney, heart, Liver).The earliest responses and largest number of affected genes occurred in tissues (PBMCs, spleen and lung) with the highest content of both T-cells and monocyte/macrophages, the direct cellular targets of SEB. In contrast, the response of liver, kidney and heart was delayed and involved fewer genes, but revealed a dominant genetic program that was seen in all 6 tissues. Many of the 85 uniquely annotated transcripts participating in this shared genomic response have not been previously linked to SEB. Global gene-expression changes measured serially across multiple organs identified new candidate mechanisms of SEB-induced death.
Overall design Toxin or saline (control) was administered to male C3H/HeJ mice in 5 independent experiments. Toxin or saline was administered i.n. followed by an i.p dose two hours later. Lung, liver, heart, spleen and kidney were harvest and preserved for tRNA purification at each time point. Each PBMC sample corresponded to a pooled sample (10 mice per time point). Samples from control animals were collected at time 0, 2.75 h, 5 h and 24 h. Samples from SEB treatment were collected at 0h, 2.75h, 5 h and 24 h. Only 4 set of samples per tissue type were used for microarray.
