Description
We performed mRNA transcriptional profiling on Drosophila S3 cells after 4 hours treatment with novel lipid storage inhibitors belonging to three different chemotypes. Overall design: Profiling of RNA expression after treatment with three pairs of active/inactive compounds or DMSO as a control in triplicates and without treatment in the presence/absence of oleic acid in sextuplicate.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
SF-1 is a nuclear receptor transcription factor playing a key role in adrenogonadal development and in adrenocortical tumorigenesis when overexpressed. NRSF/REST is a transcriptional repressor that represses expression of neuronal genes in non-neural tissues. Some data suggest that SF-1 and NRSF/REST can functionally interact in adrenocortical cancer cells.

Affymetrix Rhesus Macaque Genome Array (rhesus)
Description
It is often overlooked that human ESCs are generated from in vitro cultured, often surplus/discard, embryos considered unsuitable for transfer in infertility clinics. In vitro culture of preimplantation embryos has been associated with a number of perturbations, including ultrastructure, gene expression, metabolism and post-transfer development. We report here the transcriptional profiles characteristic of ESC lines generated from either in vitro cultured or in vivo derived embryos.

- Illumina humanRef-8 v2.0 expression beadchip
Description
Numerous studies have shown the potential of spermatozoal RNAs to delineate failures of spermatogenic pathways in infertile samples. However, the RNA contribution of normal fertile samples still needs to be established in relation to transcripts consistently present in human spermatozoa. We report here the spermatozoal transcript profiles characteristic of 24 normally fertile individuals. RNA was extracted from the purified sperm cells of ejaculate and hybridized to Illumina Human-8 BeadChip Microarrays

Description
The Pml gene is essential to the formation of PML nuclear bodies, domains which have been associated with various functions such as apoptosis/senescence, DNA repair and cell proliferation( Lallemand-Breitenbach 2010). PML-NBs formation is regulated by cellular stress including oxidative stress(Jeanne 2010, de The 2012). To investigate the role of PML in ROS response in vivo, we analyse the expression difference to the acetaminophen toxicity, which is initiated by ROS, in Pml wt and Pml KO mice.

Description
PML nuclear bodies (NBs) recruit partner proteins -including p53 and its regulators- controlling their abundance or function. Investigating arsenic sensitivity of acute promyelocytic leukemia, we proposed that PML oxidation promotes NB-biogenesis. Yet, physiological links between PML and oxidative stress response in vivo remain unexplored. Here we identify PML as a reactive oxygen species (ROS) sensor. Pml-/- cells accumulate ROS, while PML expression decreases ROS levels. Unexpectedly, Pml-/- embryos survive acute glutathione depletion. Moreover, Pml-/- animals are resistant to acetaminophen hepatotoxicity or fasting-induced steatosis. Molecularly, Pml-/- animals fail to properly activate oxidative stress-responsive p53 targets, while NRF2 response is accelerated. Finally, in an oxidative stress-prone background, Pml-/- animals display a longevity phenotype, likely reflecting decreased basal p53 activation. Thus, similar to p53, PML exerts basal anti-oxidant properties, but also drives oxidative stress-induced changes in cell survival/proliferation or metabolism in vivo. Through NB-biogenesis, PML therefore couples ROS-sensing to p53 responses, shedding a new light on PML role in senescence or stem cell biology.
