Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Human embryonic stem cells (hESCs) replicate by the process of self-renewal, whilst maintaining their pluripotency. Understanding the pathways involved in the regulation of this self-renewal process will assist in developing fully-defined conditions for the proliferation of hESCS required for therapeutic applications. We previously demonstrated a role for Sphingosine-1-phosphate (S1P) in the survival and proliferation of hESCs. The present study investigates further key signalling pathways and the downstream targets of S1P.

Description
An increasing amount of evidence suggests that the small intestine may play an important role in the development of metabolic diseases, such as obesity and insulin resistance. The small intestine provides the first barrier between diet and the body. As a result, dysregulation of biological processes and secretion of signal molecules from the small intestine may be of importance in the regulation and dysregulation of whole body metabolic homeostasis. Changes in gene expression of genes involved in lipid metabolism, cell cycle and immune response may contribute to the aetiology of diet-induced obesity and insulin resistance. In the current study we present a detailed investigation on the effects a chow diet, low fat diet and high fat diet on gene expression along the proximal-to-distal axis of the murine small intestine. The reported results provide a knowledge base for upcoming studies on the role of the small intestine in the aetiology of diet-induced diseases.

- Affymetrix Drosophila Genome 2.0 Array (drosophila2)
Description
Gliogenesis in the Drosophila CNS occurs during embryogenesis and also during the postembryonic larval stages. Several glial subtypes are generated in the postembryonic CNS through the proliferation of differentiated glial cells. The genes and molecular pathways that regulate glial proliferation in the postembryonic CNS are poorly understood. In this study we aimed to use gene expressing profiling of CNS tissue enriched in glia to identify genes expressed in glial cells in the postembryonic CNS.
Publication Title
Glial enriched gene expression profiling identifies novel factors regulating the proliferation of specific glial subtypes in the Drosophila brain.

Description
Enhanced secondary Ab responses are a vital component of adaptive immunity, yet little is understood about the intrinsic and extrinsic regulators of nave and memory B cells that results in differences in their responses to Ag. Microarray analysis, together with surface and intracellular phenotyping, revealed that memory B cells have increased expression of members of the TNF receptor, SLAM, B7 and Bcl2 families, as well as the TLR-related molecule CD180 (RP105). Accordingly, memory B cells exhibited enhanced survival, proliferation and Ig secretion, as well as entered division more rapidly than nave B cells in response to both T-dependent and T-independent stimuli. Furthermore, both IgM and isotype switched memory B cells, but not nave B cells, co-stimulated CD4+ T cells in vitro through a mechanism dependent on their constitutive expression of CD80 and CD86. This study demonstrates that upregulation of genes involved in activation, co-stimulation and survival provides memory B cells with a unique ability to produce enhanced immune responses and contributes to the maintenance of the memory B cell pool.
Publication Title
Resting human memory B cells are intrinsically programmed for enhanced survival and responsiveness to diverse stimuli compared to naive B cells.

Cells were isolated from healthy human donors (n=2). Unstimulated cells. Cells were stained with CD4, CD45RA, CCR7 and CXCR7. Using flow cytometry, 4 CD4+ T cell populations were sorted: (1) Nave (CD45RA+CCR7+CXCR5-), (2) Central memory (CD45RA-CCR7+CXCR5-), (3) Effector memory (CD45RA-CCR7-CXCR5-) and (4) CXCR5+ cells (CD45RA-CCR7-CXCR5+)

Description
The accumulation of unfolded proteins in the lumen of the endoplasmic reticulum (ER) causes stress and induces the unfolded protein response (UPR) which is characterised in part by the transcriptional induction of genes involved in assisting protein folding. Translational responses to ER stress have been less well described and here we report on a genome-wide analysis of translational regulation in the response to the ER stress-inducing agent dithiothreitol (DTT) in Saccharomyces cerevisiae. Although the observed polysome profiles were similar under control and ER stress conditions microarray analysis identified transcipt-specific translational regulation. Genes with functions in ribosomal biogenesis and assembly were translationally repressed under ER stress. In contrast mRNAs for known UPR genes, including the UPR transcription factor HAC1, the ER-oxidoreductase ERO1 and the ER-associated protein degradation (ERAD) gene DER1 were enriched in polysomal fractions under ER stress conditions. In addition, we show that splicing of HAC1 mRNA is required for efficient ribosomal loading and that Gcn2p is required for normal HAC1 splicing, so shedding light on the role of this protein kinase in the UPR pathway.
