Description
We performed gene expression analysis using the SCRB-Seq method from cervical and peripheral blood antigen presenting cells that were collected from women with different cervicovaginal bacterial community types. Overall design: Cervical and peripheral blood antigen presenting cells were FACS sorted using the gating strategy: FSC vs. SSC -> Singlets -> Live CD45+ -> HLA-DR+ -> CD11c+ or CD14+. The genital bacterial microbiomes were characterized in the same women and categorized into Lactobacillus dominance, Gardnerella dominance, or Prevotella dominance.

Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
Human ES or iPS Cells were differentiated into endothelial cells (ECs) defined by expression of CD31 (PECAM1) and CD144 (VE-Cadherin) on the cell surface. All ES or iPS derived ECs were greater than 90% double positive for these two markers.

Description
We sequenced mRNA extracted from heads of a D. melanogaster population that was sedated with a stream of ethanol saturated vapor, 30 minutes before RNA extraction; and from an age-matched untreated control group. Differential gene expression between the two groups was calculated and reported. Overall design: Examination of mRNA levels in heads of D. melanogaster adult females after ethanol exposure was performed using next generation sequencing (NGS) technology.

- Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
Choroid plexuses (CP) develop early during development. They form a barrier between the blood and the cerebrospinal fluid, and fulfill important protective and nutritive functions. We used Affymetrix microarrays to assess whether CP of the lateral ventricles (LVCP) have similar functions in developing and adult brain. We identified distinct families of protective and transport genes and found that most of these genes were already well expressed during development.

Description
RNA from circulating blood reticulocytes was utilized to provide a robust description of genes transcribed at the final stages of erythroblast maturation. After depletion of leukocytes and platelets, Affymetrix HG-U133 arrays were hybridized with probe from total RNA isolated from blood sampled from 14 umbilical cords and 14 healthy adult humans.

Description
Satellite cells are the primary source of stem cells for skeletal muscle growth and regeneration. Since adult stem cell maintenance involves a fine balance between intrinsic and extrinsic mechanisms, we performed genome-wide chronological expression profiling to identify the transcriptomic changes involved during early postnatal growth till acquisition of satellite cell quiescence.

Description
To study the effect of structural changes on expression, we assessed gene expression in genomic disorder mouse models. Both a microdeletion and its reciprocal microduplication mapping to mouse chromosome 11 (MMU11), which model the rearrangements present in Smith-Magenis (SMS) and Potocki-Lupski (PTLS) syndromes patients, respectively, have been engineered. We profiled the transcriptome of five different tissues affected in human patients in mice with 1n (Deletion/+), 2n (+/+), 3n (Duplication/+) and uniallelic 2n (Deletion/Duplication) copies of the same region in an identical genetic background. The most differentially expressed transcripts between the four studied genotypes were ranked. A highly significant propensity, are mapping to the engineered SMS/PTLS interval in the different tissues. A statistically significant overrepresentation of the genes mapping to the flanks of the engineered interval was also found in the top-ranked differentially expressed genes. A phenomenon efficient across multiple cell lineages and that extends along the entire length of the chromosome, tens of megabases from the breakpoints. These long-range effects are unidirectional and uncoupled from the number of copies of the copy number variation (CNV) genes. Thus, our results suggest that the assortment of genes mapping to a chromosome is not random. They also indicate that a structural change at a given position of the human genome may cause the same perturbation in particular pathways regardless of gene dosage. An issue that should be considered in appreciating the contribution of this class of variation to phenotypic features.

Description
NSAIDs and ACE that affect prostaglandin synthesis are widely used by pregnant women. Epidemiological studies have hypothesized a potential relation of testis dysgenesis syndromes such as cryptorchidism and hypospadias to exposure to these molecules during both the first and the second trimesters of gestation. To decipher whether the embryonic gonads themselves are targets for these molecules, we analysed the impact of precocious in utero exposure to NSAIDs and ACE alone or in combination on the early development of the testis during sex determination, using therapeutic doses similar to those administrated in human medications. We found that in utero exposure to ACE, aspirin or ibuprofen affects the germ cell proliferation in embryonic testis. The whole transcriptome of 13.5 dpc (days post coïtum) treated testis suggests different mechanisms of action of these drugs and a functional interaction between both molecules used in combination, in accelerating the germ cell differentiation. We identified that ACE and ibuprofen exposure through the up-regulation of Dnmt3L expression induces advanced epigenetic reprograming of the germline and enhanced glycogen storage within the testis cords through the activation of extracellular matrix genes expression. In addition, we identified for the first time the prostaglandin production pattern in the embryonic gonad and showed that PGD2, PGE2 and PGI2 were the targets of ACE and NSAIDs drugs. These features might affect the formation and maturation of postnatal testis and secondary reproductive organs leading to male infertility in adult age. Overall design: examination of the impact of in utero exposure to NSAIDs and ACE on testis organogenesis
