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

Description
Gut microbiota and the circadian clock are both key regulators of the metabolic processes. Although recent evidence points to the impact of the circadian clock on microbiota, gut microbiota effect on diurnal host gene expression remains elusive. A transcriptome analysis of germ-free mice reveals subtle changes in circadian clock gene expression. However, a lack of microbiome leads to liver feminization and alters the expression of male-specific genes involved in lipid metabolism and xenobiotic detoxification associated with sustained activation of the Growth Hormone pathway. These results emphasize the mutual interaction of gut microbiota and its host even on unexpected functions. Overall design: Total RNA-Seq of testis and ovaries of conventional raised (convR) and Germ-free (GF) female mice under ad libitum feeding regime.

Description
Meiotic recombination is initiated by the Spo11 endonuclease, which directs DNA double strand breaks at discrete regions in the genome coined hotspots. Here we report the profiles and dynamics of histone modifications at the cores of mouse recombination hotspots in early meiotic prophase. To define the spectrum of possible regulators of histone methylation and acetylation at all stages of meiosis I, expression analyses of histone acetylases/deacetylases (HATs/HDACs) and and HMTs/HDMTs genes when comparing those expressed in spermatogonia, pre-leptotene and leptotene/zygotene versus pachytene meiotic stages.

Description
TGZ is an agonist of the nuclear receptor PPARgamma. This synthetic compound displays anticancer effects on breast cancer cells but some of them are PPARgamma independent. Delta-2-TGZ (delta-2-troglotazone) is a PPARgamma inactive TGZ derivative possessing a double bond adjoining the thiazolidinedione ring. This compound still displays anticancer efefcts. It is an interesting tool to study the PPARgamma-independent mechanisms.
