Description
Post-traumatic stress disorder is a concerning psycho behavioral disorder thought to emerge from the complex interaction between genetic and environmental factors. For soldiers exposed to combat, the risk of developing this disorder is two-fold and diagnosis is often late, when much sequela has set in. To be able to identify and diagnose in advance those at “risk” of developing PTSD, would greatly taper the gap between late sequelae and treatment. Therefore, this study sought to test the hypothesis that the transcriptome can be used to track the development of PTSD in this unique and susceptible cohort of individuals. Gene expression levels in peripheral blood samples from 85 Canadian infantry soldiers (n = 58 subjects negative for PTSD symptoms and n = 27 subjects with PTSD symptoms) were determined by RNA sequencing technology following their return from deployment to Afghanistan. Count-based gene expression quantification, normalization and differential analysis (with thorough correction for confounders) revealed significant differences in two genes, LRP8 and GOLM1 . These preliminary results provide a proof-of-principle for the diagnostic utility of blood-based gene expression profiles for tracking symptoms of post-traumatic stress disorder in soldiers returning from tour. It is also the first to report transcriptome-wide expression profiles alongside a post-traumatic symptom checklist. Overall design: Peripheral blood samples from 85 Canadian infantry soldiers (n = 58 subjects negative for PTSD symptoms and n = 27 subjects with PTSD symptoms)

Description
Analysis of the regulation of gene expression profiles by retinoblastoma-1 in Sertoli cells. Conditional knockout of Rb1 in Sertoli cells led to progressive infertiliy in male mice that occured between 10 and 14 weeks of age. Results of gene expression studies performed on 6 week-old purified Sertoli cells helped elucidate the key role of RB1 in mature, differentiated Sertoli cells.

Description
Previous studies have shown that PR is a critical regulator of ovulation. The PR-null mice (PRKO) failed to ovulate due to a failure in the rupture of the preovulatory follicles.

Description
This study describes a temporal profile of gene expression from normal human fetal testes and ovaries. Gonads from 34 fetuses between 9 weeks and 20 weeks of gestation were obtained from the Department of Pathology and the Birth Defects Research Laboratory at the University of Washington. Relative transcript levels were determined using the Affymetrix Human Genome U133A Plus 2.0 arrays.

Description
To define H3K27me3 modified genes in intestinal stem, progenitor and epithelial cells, we performed chromatin immunoprecipitation coupled with high-throughput sequencing (ChIP-Seq). We used RNA-sequencing to profile gene expression changes during intestinal stem cell differentiation into mature villus cells, as well as genes perturbed upon loss of PRC2 activity (deletion of Eed) . We find thousands of genes that change in expression including many H3K27me3 marked genes. The deregulated genes reaveal a intestinal tissue specific role of PRC2. Overall design: H3K27me3, H3K4me2 and RNA Pol2 ChIP-Seq analysis of isolated mouse intestinal stem cells, enterocyte and secretory progenitor cells, and mature villus cells. RNA seq analysis of control mouse villus cells, control intestinal stem cells and Eed-deleted villus.
