Illumina MouseWG-6 v2.0 R2 expression beadchip
Description
Analysis of the genes and cellular signalling cascades mediating the response of SCN slices to vasoactive intestinal peptide (VIP). Primary goal was to find novel genes that may be involved in circadian phase shifting for further study. Promoter analysis of significantly regulated genes and gene ontology analysis would provide information into pathways VIP acts through in the SCN.
Publication Title
Vasoactive intestinal peptide controls the suprachiasmatic circadian clock network via ERK1/2 and DUSP4 signalling.

Description
Acute viral infection typically generates functional effector CD8+ T cells that aid in pathogen clearance. However, during acute viral lower respiratory infection (LRI), lung CD8+ T cells are functionally impaired and do not optimally control viral replication, while spleen CD8+ T cells specific for the same viral epitopes remain fully functional. To better understand the mechanisms governing lung CD8+ T cell impairment, we used flow cytometry to sort anti-viral CD8+ T cells during viral LRI. Lung and spleen cells were stained with MHC-class I tetramers representing the immunodominant anti-viral CD8+ T cell epitope. We then sorted to high purity: nave CD8+ T cells, spleen epitope-specific CD8+ T cells, lung epitope-specific CD8+ cells and secondary infection lung epitope-specific CD8+ T cells. We then performed a genome wide transcriptional analysis of these cells to characterize the gene expression profile of lung CD8+ T cell impairment.

Description
We conducted a time series of transcriptomics measurements during normal ageing in C. elegans in two non-reproductive strains (fem and gem) during normal ageing (days 1 to 10 of adulthood) and used this together with a multi-omics modelling pipeline to explore the changes that take place due to ageing. Overall design: Two strains and several time points with three replicates per strain and time point.

Description
Cystic fibrosis transmembrane conductance regulator (Cftr) knockout mice present the clinical features of low body weight and intestinal disease permitting an assessment of the interrelatedness of these phenotypes in a controlled environment. To identify intestinal alterations which affect body weight in CF mice the histological phenotypes of crypt-villus axis height, goblet cell hyperplasia, and mast cell infiltrate were measured, cardiac blood samples assessed, and gene expression profiling of the ileum was completed for 12 week old (C57BL/6xBALB) F2 Cftrtm1UNC and non-CF mice presenting a range of body weight. Crypt-villus axis height decreased with increasing weight in CF, but not control, mice. Goblet cell hyperplasia and mast cell infiltration in the submucosa and muscularis externa layers of the CF intestine, were identified to be independent of bodyweight. Blood triglyceride levels were found to be significantly lower in CF mice than control mice (p = 3.02 x 10-5) but were not dependent on CF mouse body weight. By expression profiling, genes of DNA replication and lipid metabolism were among those altered in CF mice relative to non-CF controls; and no differences in gene expression were measured between samples from CF mice in the 25th and 75th percentile for weight. This study indicates that the absence of Cftr leads to altered morphology in the CF intestine the extent of which is correlated with body weight in CF mice while CF related changes in blood triglyceride levels and in the intestinal gene expression profile were not dependent on body weight in this model.

Description
Tissues are often made up of multiple cell-types. Blood, for example, contains many different cell-types, each with its own functional attributes and molecular signature. In humans, because of its accessibility and immune functionality, blood cells have been used as a source for RNA-based biomarkers for many diseases. Yet, the proportions of any given cell-type in the blood can vary markedly, even between normal individuals. This results in a significant loss of sensitivity in gene expression studies of blood cells and great difficulty in identifying the cellular source of any perturbations. Ideally, one would like to perform differential expression analysis between patient groups for each of the cell-types within a tissue but this is impractical and prohibitively expensive.

Description
Type I interferons were discovered as the primary antiviral cytokines and are now known to serve critical functions in host defense against bacterial pathogens. Accordingly, established mediators of interferon antiviral activity may mediate previously unrecognized antibacterial functions. RNase-L is the terminal component of an RNA decay pathway that is an important mediator of interferon-induced antiviral activity. Here we identify a novel role for RNase-L in the host antibacterial response. RNase-L-/- mice exhibited a dramatic increase in mortality following
