Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Astrocyte dysfunction impacts their normal function, including neuronal support, thereby contributing to neurodegenerative pathologies including Alzheimer's disease (AD). Therefore to understand the role of astrocytes in the pathogenesis of age-related disorders we analysed the gene expression profile of astrocytes with respect to Alzheimer-type pathology.
Publication Title
Microarray analysis of the astrocyte transcriptome in the aging brain: relationship to Alzheimer's pathology and APOE genotype.

- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
Triple negative breast cancer (TNBC) is the most aggressive breast cancer subtype with the worst prognosis. It is characterised by the absence of hormone receptors for estrogen, progesterone, and human epidermal growth factor 2, and as a consequence there are no targeted endocrine treatments available. TNBC patients are more likely to develop metastases and disease relapse than patients with other breast cancer subtypes. The identification of biomarkers that can be used to predict which patient is likely to develop metastatic disease remains a priority since this is the major cause of cancer-related death in these women.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Infection with Nippostrongylus brasiliensis results in persistent changes to the lung environment. Cytokine profiling reveals a sustained increase in both Th1 and Th2 transcripts. Cellular populations of macrophages display an alternative phenotype, with upregulation of YM1, Arg1, Mrc1 as well as Class II MHC. These alternatively activated alveolar macrophages (AAAMs) also increase drastically in number. Subsequent challenge with house dust mite (HDM) Dermatophagoides pteronyssinus shows a reduced allergic phenotype, with decreased fold changes in effector cell cytokines of both the Th1 and Th2 variety indicative of the new regulatory environment established in the lung by helminth infection. Histological examination of the lung environment reveals a significant decrease in eosinophila and reduced mucous production by bronchial epithelial cells.

Description
These data provide a basis for the detection of sequence based polymorphisms between the Col-1, Tsu-1, and Kas-1 accessions of Arabidopsis thaliana. The experimental data provides an initial characterization of differences among the accessions, as well as a means for improving gene expression studies with the filtering of SFP from arrays studies.

Description
Memory B cells play essential roles in the maintenance of long-term immunity and may be important in the pathogenesis of autoimmune disease, but how these cells are distinguished from their nave precursors is poorly understood. To address this, it would be important to understand how gene expression differs between memory and naive B cells in order to elucidate memory-specific functions. Using model systems that help overcome the lack of murine memory-specific markers and the low frequency of antigen-specific memory and nave cells, we undertook a global comparison of gene expression between memory B cells and their naive precursors.
Publication Title
Systematic comparison of gene expression between murine memory and naive B cells demonstrates that memory B cells have unique signaling capabilities.
