Affymetrix Murine Genome U74A Version 2 Array (mgu74av2)
Description
Mice lacking topoisomerase II (Top II) are known to exhibit a perinatal death phenotype. In the current study, transcription profiles of the brains of wild type and top2 knockout mouse embryos were generated. Surprisingly, only a small number (1-4%) of genes were affected in top2 knockout embryos. However, the expression of nearly 30% of developmentally regulated genes was either up- or down-regulated.

Description
Estrogens have been reported to activate several processes via membrane binding to either classic estrogen receptors (ERs) or GPR30. We have used either estradiol or BSA-conjugated estradiol in order to initiate membrane-initiated actions and ICI 172,780 (ICI) or G15 to explore ER- and GPR30-related transcription. Our results show that the majority of G15-inhibited transcription is depending on ERs, as it is also inhibited by ICI. However, a small number of transcripts, related to specific actions/pathways is either exclusively inhibited by G15, providing evidence about a specific GPR30 signature, or not inhibited by ICI or G15 suggesting the existence of another, yet unidentified estrogen receptor.

Description
Anamniotes, rodents and man maintain a pool of adult neural stem cells around the central canal in the spinal cord representing an attractive cellular source for endogenous repair. Cell diversity and genes specific for this niche are still ill-defined in mammals. To identify genes specifically expressed in the niche, we microdissected (with laser) the central canal region and the adjacent tissue in human and mice adult tissues. Total RNA was isolated and used to probe affymetrix microarrays

Description
Background: Constant hypoxia (CH) and intermittent hypoxia (IH) occur during several pathological conditions such as asthma and obstructive sleep apnea. Our research is focused on understanding the molecular mechanisms that lead to injury or adaptation to hypoxic stress using Drosophila as a model system. Our current genome-wide study is designed to investigate gene expression changes and identify protective mechanism(s) in D. melanogaster after exposure to severe (1% O2) intermittent or constant hypoxia.

Description
Interferon is effective at inducing complete remissions in patients with Chronic Myelogenous Leukemia (CML), and evidence supports an immune mechanism. Here we show that the Type I Interferons (alpha and beta) regulate expression of the Interferon consensus sequence binding protein (ICSBP) in bcr-abl transformed cells and as shown previously for ICSBP, induce a vaccine-like immunoprotective effect in a murine model of bcr-abl induced leukemia. We identify the chemokines CCL6 and CCL9 as genes prominently induced by the Type I Interferons and ICSBP, and demonstrate that these immunomodulators are required for the immunoprotective effect of ICSBP expression. Insights into the role of these chemokines in the anti-leukemic response of interferons suggest new strategies for immunotherapy of CML.
