Description
To examine the role of SPS1 in mammals, we generated a Sps1 knockout mouse and found that systemic SPS1 deficiency was embryonic lethal. Embryos were clearly underdeveloped by E8.5 and virtually reabsorbed by E14.5. Removal of Sps1 specifically in hepatocytes using Albumin-cre preserved viability, but significantly affected expression of a large number of mRNAs involved in cancer, embryonic development and the glutathione system. Particularly notable was the extreme deficiency of glutaredoxin 1 (GLRX1) and glutathione-S-transferase omega 1. To assess these phenotypes at the cellular level, we targeted the removal of SPS1 in F9 cells, a mouse embryonal carcinoma cell line, which recapitulated changes in the glutathione system proteins. We further found that several malignant characteristics of SPS1-deficient F9 cells were reversed, suggesting that SPS1 has a role in supporting and/or sustaining cancer. In addition, the increased ROS levels observed in F9 SPS1/GLRX1 deficient cells were reversed and became more like those in F9 SPS1 sufficient cells by overexpressing mouse or human GLRX1. The results suggest that SPS1 is an essential mammalian enzyme with roles in regulating redox homeostasis and controlling cell growth.

Description
The 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.

Description
Retinoid X receptor (RXR)-gamma is a nuclear receptor-type transcription factor expressed mostly in the skeletal muscle, and regulated by nutritional conditions. Previously, we established transgenic mice overexpressing RXR-gamma in the skeletal muscle (RXR-gamma mice), which showed lower blood glucose than the control mice. We used microarrays to investigate their glucose metabolism gene expression change.
Publication Title
Increased systemic glucose tolerance with increased muscle glucose uptake in transgenic mice overexpressing RXRγ in skeletal muscle.
