Affymetrix Mouse Expression 430A Array (moe430a)
Description
The goal of this study was to examine whether immune responses to Plasmodium chabaudi infection differ between the sexes and are altered by the presence of gonadal steroids. Gonadally-intact males were more likely than intact females to die following P. chabaudi infection, exhibit slower recovery from infection-associated weight loss, hypothermia, and anemia, have reduced IFN-associated gene expression and IFN production during peak parasitemia, and produce less antibody during the recovery phase of infection. Gonadectomy of male and female mice altered these sex-associated differences, suggesting that sex steroid hormone, in particular androgens and estrogens, may modulate immune responses to infection.

Description
The functions of key oncogenic transcription factors independent of context have not been fully delineated despite our richer understanding of the genetic alterations in human cancers. The MYC oncogene, which produces the Myc transcription factor, is frequently altered in human cancer and is a major regulatory hub for many cancers. In this regard, we sought to unravel the primordial signature of Myc function by using high-throughput genomic approaches to identify the cell-type independent core Myc target gene signature. Using a model of human B lymphoma cells bearing inducible MYC, we identified a stringent set of direct Myc target genes via chromatin immunoprecipitation (ChIP), global nuclear run-on assay, and changes in mRNA levels. We also identified direct Myc targets in human embryonic stem cells (ESCs). We further document that a Myc core signature (MCS) set of target genes is shared in mouse and human ESCs as well as in four other human cancer cell types. Remarkably, the expression of the MCS correlates with MYC expression in a cell-type independent manner across 8,129 microarray samples, which include 312 cell and tissue types. Furthermore, the expression of the MCS is elevated in vivo in Em-Myc transgenic murine lymphoma cells as compared with premalignant or normal B lymphocytes. Expression of the MCS in human B cell lymphomas, acute leukemia, lung cancers or Ewing sarcomas has the highest correlation with MYC expression. Annotation of this gene signature reveals Myc's primordial function in RNA processing, ribosome biogenesis and biomass accumulation as its key roles in cancer and stem cells.

Description
We hypothesize that gene expression in the Type II cells of Nrf2+/+ and Nrf2-/- mice are divergent thus contributing the cell growth. More specifically, type II cells from Nrf2-/- mice have increased reactive oxygen species that cause the impaired cell growth. In order to test these hypotheses at the gene expression level, we utilized microarray analysis to examine transcriptional differences between Nrf2+/+ and Nrf2-/- cells.

Description
We hypothesize that gene expression in the lungs of this RI panel are divergent thus contributing to the disparity in their phenotypes. More specifically, (1) B6 mice tend to have a much smaller lung volume than the C3 mice while the F1 appears to be like the B6 in lung structure and function. We postulate that their gene expression differences would reflect this. (2) The diversity in the phenotypes of this RI panel could be explained by a few genes whose expression spectrum across this panel could explain the physiological spectrum. In order to test these hypotheses at the gene expression level, we utilized microarray analysis to examine transcriptional differences among lungs of these strains of mice.

Description
We hypothesize that gene expression in the CS-exposed lungs of this strain (A/J) of mice would be able to give clues about the molecular mechanism of emphysema development, thus contributing to this phenotype. More specifically, although imbalance in oxidants/antioxidants and proteinase/antiproteinase pathways drives the pathogenesis of COPD, the molecular mechanisms involved in the development of emphysema are poorly understood. In order to test this hypothesis at the gene expression level, we utilized microarray analysis to examine transcriptional differences between CS-exposed and Air-exposed groups of mice.
