Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Down syndrome (DS), a genetic condition leading to intellectual disability, is characterized by triplication of human chromosome 21. Neuropathological hallmarks of DS include abnormal central nervous system development that manifests during gestation and extends throughout life. As a result, newborns and adults with DS exhibit cognitive and motor deficits and fail to meet typical developmental and lack independent life skills. A critical outstanding question is how DS-specific prenatal and postnatal phenotypes are recapitulated in different mouse models. To begin answering this question, we developed a life span approach to directly compare differences in embryonic brain development, cellularity, gene expression, neonatal and adult behavior behavior in three cytogenetically distinct mouse models of DSTs1Cje, Ts65Dn and Dp16/1Yey (Dp16).

Description
Group 2 innate lymphoid cells (ILC-2s) regulate immune responses to pathogens, allergens, tissue remodeling and metabolic homeostasis in response to cytokines. Positive regulation of ILC-2s through ICOS has been recently elucidated but co-receptor mediated negative regulatory axis is yet to be defined.

Description
CD8+ T cells are pre-programmed for cytotoxic differentiation. However, a subset of effector CD8+ T cells (Tc17) produce IL-17 and fail to express cytotoxic genes. Here, we show that the transcription factors directing IL-17 production inhibit cytotoxicity despite persistent Runx3 expression. Cytotoxic gene repression did not require the transcription factor Thpok. We further show that STAT3 restrained cytotoxic gene expression in CD8+ T cells and that RORgt represses cytotoxic genes by inhibiting the functions but not the expression of the cytotoxic transcription factors T-bet and Eomesodermin. Thus, the transcriptional circuitry directing IL-17 expression inhibits cytotoxic functions.

Description
The biological functions of histone demethylases Jmjd3 and Utx remain poorly understood. We assessed such functions in developing T cells, using conditional (CD4-Cre-mediated) gene disruption, by inactivating Kdm6a and Kdm6b, respectively encoding Utx and Jmjd3, in immature CD4+CD8+ thymocytes. We compared microarray gene expression in mature (Va2hi CD24lo) mutant and wild-type CD4+CD8- thymocytes carrying the OT-II TCR transgene.

Description
We found constitutive upregulation and higher degree induction of drug metabolism and disposition-related genes in a three-dimensional HepG2 culture. The upregulated genes are those believed to be regulated by different regulatory factors. The global gene expression analysis by Affymetrix GeneChip indicated that altered expressions of microtubule-related genes may change expressed levels of drug metabolism and disposition genes. Stabilization of the microtubule molecules with docetaxel, a tubulin stabilizing agent, in the two-dimensional culture showed gene expression patterns similar to those in the three-dimensional culture, indicating that culture environment affects drug metabolism functions in HepG2 cells.
