Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
Hyperhomocysteinemia (HHcy) causes cardiovascular dysfunction and is associated with many complications during pregnancy related to reduced NO bioactivity. The mechanisms of HHcy on the NO-dependent control of myocardial metabolism was compared with L-NAME, which directly inhibits NO bioavailability, treated animals.

Description
There is cardiac dysfunction in male eNOS (-/-) with age and 50% mortality at 21M. It was of interest to investigate the gene expression profile of aged eNOS (-/-) male in comparison to (+/+) in order to explore the genetic markers and molecular mechanisms leading to heart failure. RNA was extracted from the left ventricle from male (-/-) (n=3) and (+/+) (n=4) at the age of 21M.

Description
Cranial placodes contribute to all sense organs and sensory ganglia in the vertebrate head. Despite their diversity they originate from a common pool of Six1/Eya2+ progenitors. In a molecular screen we identify new factors upstream of the Six1/Eya2 cassette and use these to dissect the transcriptional hierarchy that controls progenitor specification. We find that although two different tissues, the lateral head mesoderm and the prechordal mesendoderm, induce placode progenitors, both initiate a common transcriptional state, but over time gradually impart regional character.

Cell interactions, signals and transcriptional hierarchy governing placode progenitor induction.

Description
Polycomb repressive complex 2 (PRC2) catalyzes histone H3K27me3, which characterizes many silenced genes including those on the inactive X-chromosome. Here we interrogate the role of core PRC2 protein EED in X-linked gene silencing by assessing allele-specific X-linked gene expression in WT and Eed-/- hybrid mouse trophoblast stem cells (TSCs) harboring a 129/S1-derived maternal X-chromosome and a JF1/Ms-derived paternal X-chromosome. This study generates mRNA-seq data for WT and Eed-/- TSCs, which undergo imprinted inactivation of the paternal X-chromosome. RNA-seq data was mapped allele-specifically to in silico strain-specific maternal and paternal reference genomes, generated based on known single nucleotide polymorphisms. We find that EED loss abrogates H3K27me3 and expression of Xist lncRNA, which is required for X-inactivation, however, despite the absence of H3K27me3 and Xist, only a subset of PRC2 target genes are derepressed in Eed-/- TSCs. Overall design: RNA-seq profiles of four WT (Eed +/+ and Eed fl/fl) and three EED null (Eed -/-) female TS cell lines were generated through strand-specific 100 bp paired-end sequencing on the Illumina HiSeq2000

Description
The estrogen receptor-alpha (ER) determines breast cancer cell phenotype and is a prognostic indicator. A better understanding of the mechanisms controlling ER function may uncover improved strategies for the treatment of breast cancer. Proteasome inhibition was previously reported to regulate estrogen-induced transcription but the mechanisms by which it influences ER function remain controversial. In this study we investigated the transcriptome-wide effects of the proteasome inhibitor Velcade on estrogen-regulated transcription in MCF7 human breast cancer cells and demonstrate a specific global decrease in estrogen-induced transcription.
