Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
Glioblastoma multiforme (GBM) is a highly malignant primary central nervous neoplasm characterized by tumor cell invasion, robust angiogenesis, and a mean survival of 15 months. Human cytomegalovirus (HCMV) infection is present in > 90% of GBMs, although the role the virus plays in GBM pathogenesis is unclear. We report here that a majority of human GBM tumors express HCMV pp71, which has previously been found to promote cell cycle progression and viral replication, and that pp71 is expressed preferentially within the CD133+ cancer stem cell-like subpopulation. Overexpression of pp71 in adult neural precursor cells (NPCs) resulted in a dramatic induction of stem cell factor (SCF) gene expression, which has been identified as an important pro-angiogenic factor in GBM.

Description
We hypothesized that broad-scale expression profiling would provide insight into the regulatory pathways that control gene expression in response to stress, and potentially identify novel heat-responsive genes. HEp2 cells were heated at 37 to 43 C for 60 min to gauge the heat shock response, using as a proxy inducible HSP-70 quantified by western blot analysis. Based on these results, microarray experiments were conducted at 37, 40, 41, 42 and 43C (3 replicates/temperature x 5 groups = 15 U95Aver2 GeneChips). Using linear modeling, we compared the sets of microarrays at 40, 41, 42 and 43C with the 37C baseline temperature and took the union of the genes exhibiting differential gene expression signal to create two sets of heat shock response genes, each set reflecting either increased or decreased RNA abundance. Leveraging human and mouse orthologous alignments, we used the two lists of co-expressed genes to predict transcription factor binding sites in silico, including those for heat shock factor 1 (HSF1) and heat shock factor 2 (HSF2) transcription factors. We discovered HSF1 and HSF2 binding sites in 15 genes not previously associated with the heat shock response. We conclude that microarray experiments coupled with upstream promoter analysis can be used to identify novel genes that respond to heat shock. Additional experiments are required to validate these putative heat shock proteins and facilitate a deeper understanding of the mechanisms involved during the stress response.

Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
We introduced the HCMV IE1 gene into a mouse model of spontaneous glioma driven by p53KD and overexpression of Ras and PDGF and compared the transcriptomes of mouse gliomas +/- IE1. The following plasmids were utilized for glioma induction in equal parts: pT2/C-Luc/PGK-SB100, pT2/Cag-NrasV12, pT2/shP53/GFP4/mPDGF, and pT2/Cag-IE1 or pT2/C-Neo.

Description
Lymphocytes are adversely affected during sepsis. Some CD4+ splenocytes undergo apoptosis while others become Th2 polarized. The molecular determinants of these phenotypic changes are not known. Here we compare the transcriptional response of septic CD4 splenocytes to CD4 splenocytes from sham-manipulated animals 6h after sepsis and identify an early transcriptional component to the septic CD4+ splenocyte phenotype.
Publication Title
Splenic CD4+ T cells have a distinct transcriptional response six hours after the onset of sepsis.

Description
Periostin participates in different processes involved in connective tissue homeostasis. It is also involved in repairment of damaged tissues. We used the osteoblast murine cell line MC3T3-E1 cell line to show how overexpresion of periostin is able to increase their adhesion properties while diminishing their migration capacity. By differential gene expression we evaluated putative targets involved in those cellular properties.
