Estrogen receptor alpha is a major contributor to estrogen-mediated fetal testis dysgenesis and cryptorchidism.

Failure of the testes to descend into the scrotum (cryptorchidism) is one of the most common birth defects in humans. In utero exposure to estrogens, such as 17beta-estradiol (E2) or the synthetic estrogen diethylstilbestrol (DES), down-regulates insulin-like 3 (Insl3) expression in embryonic Leydig cells, which in turn results in cryptorchidism in mice. To identify the molecular mechanism whereby xenoestrogens block Insl3 gene transcription, we performed a microarray analysis of wild-type or es ...[more]

Translation profiling of human lung fibroblasts treated or not with rapamycin to better understand the molecular mechanism behind alternative translational routes

Project description:Deregulation of translational control is frequently implicated in the establishment and maintenance of the cancer phenotype. Anti-cancer drugs targeting protein synthesis are confronted by the problem that genes can exploit alternative translational mechanisms. To better understand the molecular mechanism behind these alternative translational routes we have exploited an ex-vivo assay that follows a competitive re-recruitment of cellular mRNAs onto polysomes in cells treated or not with rapamycin.

Transcription profiling of wild type and delta-sba1 yeast treated with radicicol to study gene regulation by sba1

Project description:We wanted to study regulation of gene regulation by sba1 (ortholog of mammalian p23) in yeast. sba1/p23 binds to Hsp90 and acts as a co-chaperone. We have a small molecule, radicicol, an analog of geldanamycin to inhibit the binding of p23 to Hsp90. Consequently, we have analyzed the gene expression profile in 4 conditions, wt, delta-sba1; and when Hsp90 function is impaired, that is, wt and delta-sba1 treated with radicicol.

Transcription profiling of yeast wild type and yku70, esc1, sir3 or rif1 knock-outs treated with splitomycin to study telomeric sequestration of SIRs

Project description:Budding yeast telomeres and cryptic mating-type loci are anchored at the nuclear envelope, forming foci that sequester Silent information regulators (SIR factors), much as heterochromatic chromocenters in higher eukaryotes sequester HP1. Here we examine the impact of such subcompartments for regulating transcription genome-wide. We show that the efficiency of subtelomeric reporter gene repression depends not only on the strength of SIR factor recruitment by cis-acting elements, but also on the accumulation of SIRs in perinuclear foci, which result from the clustering of telomeres. To monitor the effects of disrupting this subnuclear compartment, we performed microarray analyses under conditions that eliminate telomere anchoring, while preserving SIR complex integrity. We found 60 genes reproducibly misregulated. Among those with increased expression, 22% were within 20kb of a telomere, confirming that NE anchoring helps repress natural subtelomeric genes. In contrast, loci that were down-regulated were distributed over all chromosomes. Half of this ectopic repression was SIR-complex dependent. We conclude that released SIR factors can promiscuously repress transcription at nontelomeric genes despite the presence of "anti-silencing" mechanisms. Bioinformatic analysis revealed that promoters bearing the PAC (RNA Polymerase A and C promoters) or Abf1 binding consenses are consistently down-regulated by mislocalization of SIR factors. Thus, the normal telomeric sequestration of SIRs not only favors subtelomeric repression, but prevents promiscuous effects at a distinct subset of promoters. This demonstrates that patterns of gene expression can be regulated by changing the spatial distribution of repetitive DNA sequences that bind repressive factors.

Transcription profiling of cortical collecting duct/connecting nephron tissue from mice treated with aldosterone, canrenoate vs. controls to identify gene products regulated by aldosterone in target cells

Project description:The mineralocorticoid hormone aldosterone controls sodium reabsorption and blood pressure largely by regulating the cell-surface expression and function of the epithelial sodium channel ENaC in target kidney tubules. Part of the stimulatory effect of aldosterone on ENaC is mediated by the induction of SGK1, a kinase that interferes with the ubiquitylation of ENaC by ubiquitin-protein ligase Nedd4-2. We performed a microarray study in order to investigate which other gene products are rapidly regulated by aldosterone in target cells that participate to the control of Na+ reabsorption and K+ secretion.

Transcription profiling of S. cerevisiae (budding yeast) ume6 deletion strains vs wild-type in different media to determine the complement of Ume6 dependent genes during mitosis and meiosis

Project description:To determine the complement of Ume6-dependent genes expressed during mitosis and/or meiosis in budding yeast we compared wild-type and<br>ume6 deletion strains using Yeast 2.0 high density oligonucleotide microarrays (GeneChips). Samples were analysed from cells growing in rich medium with fermentable (glucose) and non-fermentable (acetate) carbon sources and from cells undergoing meiosis and spore formation in sporulation medium. Expression data were combined with data from a genome-wide Ume6 DNA binding assay and Ume6-target site prediction to identify the most likely direct target genes of Ume6.

Project description:To study the role of the testis determining gene Sox9 after testis induction, conditional inactivation of Sox9 was achieved with the help of an AMH-Cre line. Mutant mice are fertile up to about 3 months of age, becoming sterile afterwards. Expression profiles should help to reveal the underlying cause.
