View SamplesThe adult mammalian brain is composed of distinct regions that have specialized roles. The BF/POA regions are thought to have an important role in the regulation of sleep/wake behavior. However, genetic markers of the responsible cells for the regulation of sleep/wake behavior are largely unknown. To identify the molecular markers of the BF/POA regions, we sampled the BF/POA regions and compared gene expression in the BF/POA regions with those of other brain regions which we previously reported in the BrainStars (B*) project, in which we sampled ~50 small brain regions, including sensory centers and centers for motion, time, memory, fear, and feeding.

View SamplesThe Hamner data set (endpoint A) was provided by The Hamner Institutes for Health Sciences (Research Triangle Park, NC, USA). The study objective was to apply microarray gene expression data from the lung of female B6C3F1 mice exposed to a 13-week treatment of chemicals to predict increased lung tumor incidence in the 2-year rodent cancer bioassays of the National Toxicology Program. If successful, the results may form the basis of a more efficient and economical approach for evaluating the carcinogenic activity of chemicals. Microarray analysis was performed using Affymetrix Mouse Genome 430 2.0 arrays on three to four mice per treatment group, and a total of 70 mice were analyzed and used as the MAQC-II's training set (GEO Series GSE6116). Additional data from another set of 88 mice were collected later and provided as the MAQC-II's external validation set (this Series). The training dataset had already been deposited in GEO by its provider and its accession number is GSE6116.

View SamplesTo test the regulatory effects of Dmrt5 on gene expression, we designed tetracycline inducible lines of Dmrt5 transgenic mouse ESCs. Overexpression of Dmrt5 was induced upon addition of Doxycycline (Dox). To evaluate the effects of Dmrt5 on gene expression in different stages of in vitro differentiated NPC derived from mouse embryonic stem cells (ESC), we analyzed gene expression profiles at differentiation day 7 and day 9 with or without Dox. The data revealed that overexpression of Dmrt5 in in vitro differentiated neural progenitor cells (NPC) regulates gene expression. Addition of Dox to the medium of the control cell line rtTA did not significantly alter gene expression profile, demonstrating that the observed effects were through induction of Dmrt5, but not simply through Dox.

View SamplesThese studies address temporal changes in gene expression during spontaneous sleep and extended wakefulness in the mouse cerebral cortex, a neuronal target for processes that control sleep; and the hypothalamus, an important site of sleep regulatory processes. We determined these changes by comparing expression in sleeping animals sacrificed at different times during the lights on period, to that in animals sleep deprived and sacrificed at the same diurnal time.
