Description
We performed RNA-seq and miRNA-seq in fetal RPE cells differentated during 5 weeks in a transwell set up Overall design: Samples from days 7, 14, 21, 28 and 35 were characterized. Cells were grown in a proliferation medium during the first week (EpiCM) and then in a maturation medium (MAM medium) that enahnces differentiation towards the desired phenotype.

Affymetrix Drosophila Genome 2.0 Array (drosophila2)
Description
Phenobarbital is a well studied xenobiotic compound. In this study, we describe the genomic responses in fruit flies and examine whether animals mutant for DHR96, an ortholog of xenobiotic nuclear receptors PXR and CAR, plays a role in mediating xenobiotic responses in Drosophila.

Description
DHR96 plays a role in regulating xenobiotic responses in Drosophila. Using a gain-of-function approach we test whether DHR96 is sufficient to affect detoxification genes in the absence of a xenobiotic insult.

Description
Purpose: The DBA/2J mouse is a model for secondary angle-closure glaucoma due to iris atrophy and pigment dispersion, which ultimately leads to increased intraocular pressure (IOP). We sought to correlate changes in retinal gene expression with glaucoma-like pathology by performing microarray analysis of retinal RNA from DBA/2J mice at 3 months before disease onset, and at 8 months, after IOP elevation. Methods: IOP was monitored monthly in DBA/2J animals by Tono-Pen and animals with normal (3 months) or elevated IOP (8 months) were identified. RNA was prepared from 3 individual retinas at each age, and the RNA was amplified and used to generate biotin-labeled probe for high density mouse Affymetrix arrays (U430.2). A subset of genes was selected for confirmation by quantitative RT-PCR using independent retina samples from DBA/2J animals at 3, 5 and 8 months of age, and compared to retinas from C57BL/6J control animals at 3 and 8 months. Results: There were changes in expression of 68 genes, with 32 genes increasing and 36 genes decreasing at 8 months versus 3 months. Upregulated genes were associated with immune response, glial activation, signaling and gene expression, while down-regulated genes included multiple crystallin genes. Significant changes in 9 upregulated genes and 2 downregulated genes were confirmed by quantitative RT-PCR, with some showing changes in expression by 5 months. Conclusions: DBA/2J retina shows evidence for glial activation and an immune-related response following IOP elevation, similar to what has been reported following acute elevation of IOP in other models.

Description
Adult BALB/c female mice were injected intraperitoneally with a single dose at 20 mg per kg of antisense oligonucleotide either against miR-29a (5-TAACCGATTTCAGATGGTGCTA-3) or against a scrambled sequence (5-TCATTGGCATGTACCATGCAGCT-3 Antisense oligonucleotides contained 2-O-methoxyethyl (2-MOE), 2-flouro (2-F) 2'-alpha-flouro units with a phosphorothioate backbone (Regulus Therapeutics). Six days following the injection, liver was isolated, total RNA was prepared as described above, and the RNA was amplified and biotinylated using the MessageAmp Premier kit (Ambion). Samples (n=4 each experimental and control) were hybridized to Affymetrix GeneChip Mouse Genome 430 2.0 Arrays in the Childrens Hospital of Philadelphia Nucleic Acids Core Facilityand analyzed with the assistance of the Penn Bioinformatics Core. Probe intensities were normalized using the GCRMA method and the significance of the log2-transformed, GCRMA-normalized signal intensities was determined using SAM

Description
Oocyte maturation, fertilization, and early embryonic development occur in the absence of gene transcription. Therefore, it is critical to understand at a global level the post-transcriptional events that are driving these transitions. Here, we have used a systems approach by combining polysome mRNA profiling and bioinformatics to identify RNA binding motifs in mRNAs that either enter or exit the polysome pool during mouse oocyte maturation. Association of mRNA with the polysomes correlates with active translation.

Description
Our previous studies have shown that bone morphogenetic protein 2 (BMP2), a morphogen belonging to the TGF superfamily, is markedly induced in human primary endometrial stromal cells (HESC) as they undergo differentiation in response to steroid hormones and cAMP. WNT4 is a downstream target of BMP2 regulation in these cells.

Description
BACKGROUND: Dietary ABA-supplementation modulates immune and inflammatory responses in mouse models of chronic and infectious disease. However, the underlying mechanisms by which ABA elicits its immune modulatory effects are not well understood. This project used a systems approach in combination with functional and in vivo studies to investigate the target gene pathways modulated by ABA in the context of an inflammatory LPS challenge.
