Illumina Genome Analyzer IIx
Description
We sequenced the total mRNA from infected cells and detected differences in the expression of both host mRNA. We detected a small but significant suppression of T cell activation-related genes at 12 hpi. This suppression persisted and expanded by 24 hpi providing new possible markers of virus-induced T cell cytopathology. By 24 hpi the expression of over 50% of detectable host loci was also altered indicating widespread alteration of host processes including RNA processing, splicing, and transport to an extent not previously reported. In addition next-generation sequencing provided insights into the expression of non-coding RNAs including microRNA host genes. Overall design: We isolated polyadenylated RNA from SUPT1 cells infected with HIV-1 strain LAI at 12 and 24 hours post-infection (3 replicates for each time point). As controls we isolated polyadenylated RNA from mock-infected cells at 12 and 24 hours post-infection (2 replicates at 12 hours post-infection, 3 replicates at 24 hours post-infection).

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
KATP opposes depolarization of cells in the heart, smooth muscle, and other tissues by permitting the efflux of potassium ions and this efflux is evidently required to prevent unopposed vasoconstriction and insufficiency of coronary artery blood flow triggered by one or more cytokines induced in response to LPS. The cytokine(s) involved must elicit a dysfunctional response in the Kir6.1-deficient environment, and to gain further insight into the effects of the mutation, we examined the transcriptional status of whole heart, isolated from normal C57BL/6J mice or KcnJ8Md/Md mice, before and after injection of 1 g of LPS

Description
Exposure to Polychlorobiphenyls (PCBs) is known to cause serious health effects in human but the gene expression profiles leading to development of differnet diseases and disorders are not fully understood. The knowledge of global gene expression will help us to devlop early disease or disorder biomarkers for PCB induced health effects.

- Affymetrix Mouse Gene 1.1 ST Array (mogene11st)
Description
A mucus layer covers and protects the intestinal epithelial cells from direct contact with microbes. This mucus layer not only prevents inflammation but also plays an essential role in microbiota colonization, indicating the complex interplay between mucus composition-microbiota and intestinal health. However, it is unknown whether the mucus layer is influenced by age or sex and whether this contributes to reported differences in intestinal diseases in males and females or with ageing. Therefore, in this study we investigated the effect of age on mucus thickness, intestinal microbiota composition and immune composition in relation to sex. The ageing induced shrinkage of the colonic mucus layer was associated with bacterial penetration and direct contact of bacteria with the epithelium in both sexes. Additionally, several genes involved in the biosynthesis of mucus were downregulated in old mice, especially in males, and this was accompanied by a decrease in abundances of various Lactobacillus species and unclassified Clostridiales type IV and XIV and increase in abundance of the potential pathobiont Bacteroides vulgatus. The changes in mucus and microbiota in old mice were associated with enhanced activation of the immune system as illustrated by a higher percentage of effector T cells in old mice. Our data contribute to a better understanding of the interplay between mucus-microbiota-and immune responses and ultimately may lead to more tailored design of strategies to modulate mucus production in targeted groups.

Description
We demonstrate for the first time that the extracellular matrix glycoprotein Tenascin-C regulates the expression of key patterning genes during late embryonic spinal cord development, leading to a timely maturation of gliogenic neural precursor cells. We first show that Tenascin-C is expressed by gliogenic neural precursor cells during late embryonic development. The loss of Tenascin-C leads to a sustained generation and delayed migration of Fibroblast growth factor receptor 3 expressing immature astrocytes in vivo. Furthermore, we could demonstrate an upregulation of Nk2 transcription factor related locus 2 (Nkx2.2) and its downstream target Sulfatase 1 in vivo. A dorsal expansion of Nkx2.2-positive cells within the ventral spinal cord indicates a potential progenitor cell domain shift. Moreover, Sulfatase 1 is known to regulate growth factor signalling by cleaving sulphate residues from heparan sulphate proteoglycans. Consistent with this possibility we observed changes in both Fibroblast growth factor 2 and Epidermal growth factor responsiveness of spinal cord neural precursor cells. Taken together our data clearly show that Tenascin-C promotes the astroglial lineage progression during spinal cord development.
