Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
The human and mouse aryl hydrocarbon receptor (hAHR and mAHRb) share limited (58%) transactivation domain sequence identity. Compared to the mAHRb allele, the hAHR displays 10-fold lower relative affinity for prototypical ligands such as 2,3,7,8 tetrachlorodibenzo-p-dioxin (TCDD). However, in previous studies we have demonstrated that the hAHR can display a higher relative ligand binding affinity than the mAHRb for specific AHR ligands such as indirubin. Each receptor has also been shown to differentially recruit LXXLL co-activator-motif proteins and to utilize different TAD subdomains in gene transactivation. Using hepatocytes isolated from C57BL6/J mice (Ahrb/b) and AHRTtr transgenic mice which express hAHR protein specifically in hepatocytes, we investigated whether the hAHR and mAHRb differentially regulate genes. Microarray and quantitative-PCR analysis of Ahrb/b and AHRTtr primary-mouse hepatocytes treated with 10 nM TCDD revealed that a number of established AHR target genes such as Cyp1a1 and Cyp1b1 are significantly induced by both receptors. Remarkably, of the 1752 genes induced by mAHRb and 1186 genes induced by hAHR, only 265 genes (<10%) were significantly activated by both receptors in response to TCDD. Conversely of the 1100 and 779 genes significantly repressed in mAHRb and hAHR hepatocytes respectively, only 462 (<25%) genes were significantly repressed by both receptors in response to TCDD treatment. Genes identified as differentially expressed are known to be involved in a number of biological pathways, including cell proliferation and inflammatory response which suggests that compared to the mAHRb, the hAHR may play contrasting roles in TCDD-induced toxicity and endogenous AHR-mediated gene regulation.

Description
CD4+ and CD8+ T cells isolated from wild-type and Foxo1-deficient mice were analyzed by global gene expression profiling with Affymetrix array MOE 430 2.0. Results indicate Foxo1 regulates the expression of genes encoding positive regulators of T cell activation, differentiation, homeostasis, cell adhesion, cell migration, and cellular stress responses.

Description
Growth restriction, craniofacial dysmorphology and central nervous system defects are the main diagnostic features of fetal alcohol syndrome. Studies in humans and mice have reported that the growth restriction can be prenatal and/or postnatal, but the underlying mechanisms remain unknown. We recently described a mouse model of moderate gestational ethanol exposure that produces measurable phenotypes in line with fetal alcohol syndrome, e.g. craniofacial changes and growth restriction in adolescent mice. Here we further characterize the growth restriction phenotype by measuring body weight at gestational day 16.5, cross-fostering from birth to weaning, and extending our observations into adulthood. Furthermore, in an attempt to unravel the molecular events contributing to the growth phenotype, we have compared gene expression patterns in the liver and kidney of non-fostered ethanol-exposed and control mice at postnatal day 28. We find that the ethanol-induced growth phenotype is not detectable prior to birth, but is present at weaning, even in mice that have been cross-fostered to unexposed dams. This suggests a postnatal growth restriction phenotype that is not due to deficient postpartum care by dams that drank ethanol, but rather a physiological result of ethanol exposure in utero. We also find that, despite some catch-up growth after five weeks of age, the effect extends into adulthood, consistent with longitudinal studies in humans. Genome-wide gene expression analysis revealed interesting ethanol-induced changes in the liver, including genes involved in the metabolism of exogenous and endogenous compounds, iron homeostasis and lipid metabolism.

Description
Purpose: To compare the transcriptomes of IL-21-expressing, IL-21 and IL-4-expressing, and IL-4 expressing follicular helper T (Tfh) cells and Th2 cells in the spleen at 8 days following helminth infection Methods: Cell sorting of the populations was done for CD4+B220-CD44hiCXCR5hiPD-1hi cells of the various types, followed by mRNA purification. Overall design: CD4+Splenic T cell mRNA profiles 8 days post-infection of IL-21/IL-4 dual reporter mice with Nippostrongylus brasiliensis were generated by mRNA sequencing using Illumina HiSeq 2000.
