Description
Oligodendrocyte precursor cells from postnatal day 10 optic nerve remained in a developmentally immature state in LIF-/- mice. Partial recovery of myelin genes is seen in LIF-/- mice by postnatal day 14 in the optic nerve. Very little difference in myelin genes in the optic nerve is seen by postnatal day 35 (adult).

- Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
Seven novel and potent Raf small molecule kinase inhibitors were evaluated in 7-day oral repeat-dose rat toxicity studies. All compounds tested induced hyperplasia in multiple tissues. Microarrays were used to investigate transciptional changes associated by treatment with a single compound to gain insight into the cellular changes that may contribute to the tissue hyperplasia.

Description
Histone variant H2A.Z occupies the promoters of active and poised, bivalent genes in ESCs to regulate developmental programs, yet how it contributes to these contrasting states is poorly understood. Here, we investigate the function of H2A.Z.1 mono-ubiquitylation (H2A.Z.1ub) by mutation of the PRC1 target residues (H2A.Z.1K3R3). We show that H2A.Z.1K3R3 is properly incorporated at target promoters in murine ESCs (mESCs), however, loss of mono-ubiquitylation leads to de-repression of bivalent genes, loss of Polycomb binding, and to faulty lineage commitment. Using quantitative proteomics, we find that tandem bromodomain proteins, including the BET family member Brd2, are enriched in H2A.Z.1 chromatin. We further show that Brd2 is gained at de-repressed promoters in H2A.Z.1K3R3 mESCs whereas Brd2 inhibition restores gene silencing at these sites. Together, our study reveals an antagonistic relationship between H2A.Z.1ub and Brd2 to regulate the transcriptional balance at bivalent genes to enable proper execution of developmental programs. Overall design: RNA-Seq analysis on mouse embryonic stem cells harboring H2A.Z or H2A.Z.K3R3 (3 C-terminal lysines mutated to arginines) tagged with YFP, in the presence of a knockdown hairpin targeting the endogenous H2A.Z transcript.

- Affymetrix Human Genome U133A Array (hgu133a)
Description
Genome-wide DNA methylation patterns are established and maintained by the coordinated action of three DNA methyltransferases, DNMT1, DNMT3A, and DNMT3B. DNMT3B hypomorphic germline mutations are responsible for two-thirds of Immunodeficiency, Centromere Instability, Facial Anomalies (ICF) syndrome cases. The molecular defects in transcription, DNA methylation, and chromatin structure in ICF cells remain relatively uncharacterized.
Publication Title
DNA methyltransferase 3B (DNMT3B) mutations in ICF syndrome lead to altered epigenetic modifications and aberrant expression of genes regulating development, neurogenesis and immune function.

To investigate the differences of expression patterns in primary chicken embryo fibroblasts (CEFs) under conditions of contact-inhibition and serum starvation, we undertook a gene profiling study to characterize the transcriptomes of CEFs grown under conditions of contact inhibition, serum starvation or both, in relation to normal growing (cycling) cells.
