Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Genome-wide gene expression was obtained in three auditory brainstem nuclei (defined below), at two different ages in mice, postnatal day (P)3 and P14. The primary aim was to identify genes which are differentially expressed between the medial nucleus of the trapezoid body (MNTB) and the superior olive (LSO), at both age groups.

Description
Based on preliminary data demonstrating that macrophages are critical regulators of Helicobacter pylori colonization and gastric pathology in mice, we sought to investigate how macrophages may serve as bacterial reservoirs of intracellular H. pylori. Overall design: BMDM were isolated from WT and PPARg-/- mice and cultured with M-CSF for 7 days to promote macrophage differentiation. Fully differentiation macrophages were challenged with H. pylori strains SS1 at an MOI of 10 for 15 minutes. Extracellular bacteria was then eliminated by gentamycin treatment. Cells were collected at 0, 60, 120, 240, 360 and 720 minutes post gentamycin treatment to ascertain whole transcriptome differential gene expression during infection.

Description
Nematode derived substances are known to down regulate host immune responses in order to survive in the human host. Brugia malayi is a parasitic nematode responsible for long lasting and disabling infection known as lymphatic filariasis in humans. The therapeutic benefit of a controlled parasitic nematode infection on the course of inflammatory bowel disease (IBD) has been demonstrated in both animal and human models. However the inability of individual purified nematode proteins to recreate this beneficial effect has limited the application of component immunotherapy to human disease. This experiment addresses the hypothesis that the genes regulated by IL8 and recombinant Brugia malayi AsnRS (rBmAsnRS) are different even though it is known that both molecules interact with IL-8 receptors. Furthermore, we theorize that the signal transduction pathways activated by IL-8 and rBmAsnRS are different because it is known that the extracellular G protein loops utilized by IL-8 and rBmAsnRS to activate IL8 receptors, are different. These results obtained with a single recombinant nematode protein, rBmAsnRS, share immunological features with those observed in a whole nematode infection and include desirable features for treatment of idiopathic inflammatory diseases, such as IBD.

Description
We compared splenic Va14i NKT cells from C57BL/6 control mice and from mice injected 4 weeks earlier intravenously with 4ug/mouse of the iNKT cell antigen alpha-galactosylceramide (aGalCer). These mice were either left unstimulated or were stimulated with 1ug/mouse aGalCer i.v.. All mice were female and 8 weeks of age at the beginning of the experiment. Va14i NKT cells were enriched via magnetic selection and cell sorted for TCRb+ CD1d/aGalCer-tetramer+. Total RNA were prepared using a Qiagen RNeasy mini kit. IVT probe generation and hybridization to Affymetrix Mouse Genome 430 2.0 arrays was carried out by the Veterans Medical Research Foundation GeneChipTM Microarray located at UCSD.

Description
Previous studies indicate that the triterpene glycoside actein from the herb black cohosh inhibits growth of human breast cancer cells. This study seeks to identify genes altered in human breast cancer cells by treatment with actein, using gene expression analysis. We treated MDA-MB-453 human breast cancer cells with actein at 2 doses, 20 or 40 g/mL, for 6 or 24 h. We identified 5 genes that were activated after each of the treatments that are known to play a role in cellular responses to diverse stresses, including the DNA damage and unfolded protein responses. In addition, four genes that mediate the integrated stress response (ISR), including activating transcription factor 4, were induced under at least one of the 4 treatment conditions. We used hierarchical clustering to define clusters comprising patterns of gene expression. Two ISR genes, activating transcription factor 3 (ATF3) and DNA damage- inducible transcript 3, and lipid biosynthetic genes were activated after exposure to actein at 40 g/mL for 6 h, whereas the cell cycle genes cyclin E2 and cell division cycle 25A were repressed. Our results suggest that actein induces 2 phases of the ISR, the survival phase and the apoptotic phase, depending on the dose and duration of treatment. We confirmed the results of gene expression analysis with real-time RT-PCR for 18 selected genes and Western blot analysis for ATF3. Since actein activated transcription factors that enhance apoptosis, and repressed cell cycle genes, it may be useful in the prevention and therapy of breast cancer.
Publication Title
The growth inhibitory effect of actein on human breast cancer cells is associated with activation of stress response pathways.

Description
Growth factor independence 1b (Gfi1b) is a DNA binding repressor of transcription with vital functions in hematopoiesis. Gfi1b-null embryos die at midgestation very likely due to defects in erythro- and megakaryopoiesis. To analyze the full functionality of Gfi1b in embryonic erythropoiesis, we used conditionally deficient mice that harbor floxed Gfi1b alleles and one EpoR-Cre knock-in allele.
