Description
The etiology of autoimmune hepatitis is poorly understood but likely involves Th1 cells producing IFN-. BALB/c background TGF-1-/- mice rapidly develop fulminant Th1-mediated autoimmune hepatitis. Our aims are to profile liver gene expression in TGF-1-/- mice, to identify gene expression pathways dependent on IFN- as possible targets for rational therapy, and to test potential targets directly in vivo in mice.
Publication Title
The role of Ifng in alterations in liver gene expression in a mouse model of fulminant autoimmune hepatitis.

To examine the effects of disrupting the AML1/ETO MYND-SMRT interaction with the W692A substitution on AML1/ETO function, the global gene expression profile of mouse bone marrow LSK cells transduced with GFP was compared to that of cells transduced with either wild-type AML1/ETO or AML1/ETO harboring the W692A substitution in the MYND domain. Three independent biological replicates were assessed for both the control (GFP/MigR1) and AML1/ETO (intact MYND-SMRT interaction) conditions, whereas four independent biological replicates were assessed for the W692A (disrupted MYND-SMRT interaction) condition. The three GFP replicates were used to establish a baseline signal for comparison to both the AML1/ETO and W692A samples.

Description
In order to identify the targets of GATA4-FOG2 action in mammalian heart development we performed Affymetrix microarray comparisons of gene expression in normal and mutant at embryonic (E) day E12.5 hearts. We compared RNA samples from both Fog2-null and Gata4ki/ki mutant E12.5 hearts to the wild-type control E12.5 hearts. We reasoned that as the phenotypes of the Fog2 knockout and Gata4ki/ki mutation (a V217G mutation that specifically cripples the interaction between GATA4 and FOG proteins) are similar, we should expect to identify a similar set of differentially expressed genes in both experiments. As an additional control, we expected to find the Fog2 gene expression absent in the mutant (null) Fog2 cardiac sample, but not Gata4ki/ki sample.

Description
We have demonstrated previously that mammalian sexual differentiation requires both GATA4 and FOG2 transcription regulators to assemble the functioning testis. We have now determined that the sexual development of female mice is profoundly affected by the loss of GATA4-FOG2 interaction. We have also identified the Dkk1 gene, encoding a secreted inhibitor of canonical -catenin signaling as a target of GATA4/FOG2 repression in the developing ovary. The tissue-specific ablation of the -catenin gene in the gonads disrupts female development while in the Gata4ki/ki/Dkk1-/- or Fog2-/-/Dkk1-/- embryos the normal ovarian gene expression pattern is partially restored. Control of ovarian development by the GATA4/FOG2 complex presents a novel insight into the crosstalk of transcriptional regulation and extracellular signaling in ovarian development.

Description
Exposure to high levels of arsenic in drinking water is associated with several types of cancers including lung, bladder and skin, as well as vascular disease and diabetes. Drinking water standards are based primarily on epidemiology and extrapolation from higher dose experiments, rather than measurements of phenotypic changes associated with chronic exposure to levels of arsenic similar to the current standard of 10ppb, and little is known about the difference between arsenic in food as opposed to arsenic in water. Measurement of phenotypic changes at low doses may be confounded by the effect of laboratory diet, in part because of trace amounts of arsenic in standard laboratory chows, but also because of broad metabolic changes in response to the chow itself. Finally, this series contrasts 8hr, 1mg/kg injected arsenic with the various chronic exposures, and also contrasts the acute effects of arsenic, dexamethasone or their combination. Male C57BL/6 mice were fed on two commercially available laboratory diets (LRD-5001 and AIN-76A) were chronically exposed, through drinking water or food, to environmentally relevant concentrations of sodium arsenite, or acutely exposed to dexamethasone.

Description
Domesticated animal populations often show profound reductions in predator avoidance and fear-related behavior compared to wild populations. These reductions are remarkably consistent and have been observed in a diverse array of taxa including fish, birds, and mammals. Experiments conducted in common environments indicate that these behavioral differences have a genetic basis. In this study, we quantified differences in fear-related behavior between wild and domesticated zebrafish strains and used microarray analysis to identify genes that may be associated with this variation.
