- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
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.

Description
Salmonella species infect many vertebrate species, and pigs colonized with Salmonella enterica serovar Typhimurium (ST) are usually asymptomatic, making detection of these Salmonella-carrier pigs difficult. The variable fecal shedding of this gram-negative bacteria in such pigs is an important cause of foodborne illness and zoonotic disease. To investigate gene pathways and biomarkers associated with the variance in Salmonella shedding following experimental inoculation, we have initiated the first analysis of the whole blood transcriptional response induced by Salmonella. A population of pigs (n=40) was inoculated with ST and the peripheral blood and feces were collected between 2 and 20 days post-inoculation. Two groups of pigs with either low shedding (LS) or persistent shedding (PS) phenotypes were identified. The global transcriptional changes in response to ST inoculation were identified by Affymetrix Genechip?analysis of peripheral blood RNA at day 0 and day 2 post-inoculation.

Description
Gene arrays were used to characterize the global transcriptional alterations in skin biopsy samples of EM lesions in comparison to controls. The transcriptional pattern in EM biopsies consisted of 254 differentially regulated genes (180 induced and 74 repressed) characterized by the induction of chemokines, cytokines, Toll-like receptors, antimicrobial peptides, monocytoid cell activation markers, and numerous genes annotated as interferon (IFN)-inducible. The IFN-inducible genes included 3 transcripts involved in tryptophan catabolism (IDO1, KMO, KYNU) that play a pivotal role in immune evasion by certain other microbial pathogens by driving the differentiation of regulatory T cells.

- Affymetrix Mouse Gene 2.0 ST Array (mogene20st)
Description
The activation of vascular smooth muscle cells (VSMCs) during hypertension-induced arterial remodeling processes relies on a change of the gene expression program, i.e., up-regulation of genes to induce migration, proliferation and matrix degradation/synthesis. At the same time, genes controlling the quiescent, contractile VSMC phenotype are down-regulated. We used microarrays to detail the global program of gene expression underlying hypertension-induced vascular remodeling in the presence and absence of regulator of G-protein signaling 5 (RGS5) and identified distinct classes of down-regulated genes during vascular remodeling when RGS5 was not present.

Hypertension-evoked RhoA activity in vascular smooth muscle cells requires RGS5.

Recent work using mouse models has revealed that mTORC2, which unlike mTORC1 is not acutely sensitive to rapamycin, plays a key role in the regulation of organismal physiology. The substrates and pathways regulated by mTORC2 are at present relatively unknown

Description
Phosphate is essential for healthy bone growth and plays an essential role in fracture repair. Although phosphate deficiency has been shown to impair fracture healing, the mechanisms involved in impaired healing are unknown. More recently, studies have shown that the effect of phosphate deficiency on the repair process varied based on the genetic strain of mice, which is not characterized.

Illumina HiSeq 2500
Description
Host defense by the innate immune system requires the establishment of antimicrobial states allowing cells to cope with microorganisms before the onset of the adaptive immune response. Interferons (IFN) are of vital importance in the establishment of cell-autonomous antimicrobial immunity. Speed is therefore an important attribute of the cellular response to IFN. With much of the antimicrobial response being installed de novo, this pertains foremost to gene expression, the rapid switch between resting-state and active-state transcription of host defense genes. Our results show how mRNA expression changes upon IFNb or IFNg treatment in wild typ and Irf9-/- bone marrow derived macrophages. Overall design: Methods: Bone marrow derived macrophage mRNA of wild-type (WT) and Irf9 knock out mice (IRF9-/-) untreated, as well as 2h IFNb and IFNg treated were generated by deep sequencing, in triplicate, using Illumina sequencing.
