Description
The goal of our study was to evaluate at the systems-level, the effect of sex hormones on thymic epithelial cells (TECs). To this end, we sequenced the transcriptome of cortical and medullary TECs (cTECs and mTECs) from three groups of 6 month-old mice: males, females and males castrated at four weeks of age. In parallel, we analyzed variations in the size of TEC subsets in those three groups between 1 and 12 months of age. We report that sex hormones have pervasive effects on the transcriptome of TECs: the number of differentially expressed genes was 1,440 in cTECs and 1,783 in mTECs. Sexual dimorphism was particularly conspicuous in cTECs. Male cTECs displayed low proliferation rates that correlated with low expression of Foxn1 and its main targets. Furthermore, male cTECs expressed relatively low levels of genes instrumental in thymocyte expansion (e.g., Dll4) and positive selection (Psmb11 and Ctsl). Nevertheless, cTECs were more abundant in males than females. Accumulation of cTECs in males correlated with differential expression of genes regulating cell survival and cell differentiation. Unexpectedly, we observed that female and male sex hormones repressed promiscuous gene expression in mTECs. Since sex hormones did not affect the expression of Aire per se, they must impinge on the activity of unidentified regulator(s) of promiscuous gene expression in mTECs. The sexual dimorphism of TECs highlighted here may be mechanistically linked to the well-recognized sex differences in susceptibility to infections and autoimmune diseases. Overall design: Cortical and medullary thymic epithelial cells from 6 month-old male, female and castrated male mice were sequenced in 3 replicates (but only 2 replicates for castrated male mTECs).

Description
Thymocytes were extracted from a pool of three 8-12 week old C57BL-6 female mice. Cells were separated from stroma by gently crushing the thymi in between 2 microslides. RNA from thymocytes was extracted using the Trizol reagent and protocol, and analysed using the Illumina HiSeq 2000. Overall design: Transcriptomic analysis of a single replicate of thymocytes from a pool of three 8-12 week old C57BL-6 female mice, using the Illumina HiSeq 2000

Description
Quiescent splenic B cells purified from Cg1-cre Prmt5F/F cells and Cg1-cre control mice. Resting B cells were plated on feeder cells expressing CD40L and BAFF and supplemented with IL-4 for activation. Four days later, the resulting activated germinal center-like B cells were purified and RNA extracted and processed for HiSeq. Four independent samples of each genotype were processed and analyzed. Overall design: 2 Experiments, 2 samples of each genotype per experiment (Exp 1: Samples 1,2,7,8 ; Exp 2: Samples 3,4,5,6)_ PRMT5 FF Cg1cre: Samples 1,2,3,4_ Cg1cre controls: Samples 5,6,7,8

Description
Developmental programming is the concept that environmental factors, particularly during foetal life, can alter development, metabolism and physiology of an organism and this can have consequences later in life. There is growing interest in developmental programming in livestock species, particularly effects of maternal pregnancy nutrition, which is easy to manipulate. Recent research, using a sheep model, has shown that milk production in ewe offspring may be susceptible to maternal nutritional programming, such that over nutrition (ad libitum) of the pregnant dam, compared with maintenance nutrition, may impair their first lactation performance and result in the weaning of lighter lambs. RNA-seq was performed to identify gene expression differences as a result of maternal nutrition in ewe offspring during their first parity. Samples were collected in late pregnancy and during lactation, allowing us to examine gene expression changes during maturation of the ovine mammary gland. Overall design: Three biological replicates were sequenced for each of the treatment conditions (maternal nutrition: sub-maintenance, maintenance, and ad libitum) and time points (late pregnancy and lactation). Each biological replicate consisted of RNA from multiple individuals (late pregnancy n=3, lactation n=2).

Description
Prostate cancer (PCa) tends to be more aggressive and lethal in African Americans (AA) compared to European Americans (EA). To further understand the biological factors accounting for the PCa disparities observed in AA and EA patients, we performed gene profiling using Affymetrix human exon 1.0 ST arrays to identify the differentially expressed genes beween AA cancer and patient matched normal tissues.
