Illumina HiSeq 2500
Description
E15.5 embryos were micro-disscted from Gata4 G295S mutant mice and littermate controls, RNA was isolated using Norgen total RNA isolation, and libraries were generated with the RNA TruSeq Stranded Total RNA kit. 50 base pair paired end reads were obtained on an illumina high seq 2500. Fastq files were aligned to the mouse genome using STAR aligner. QC was performed using RNASeQC and RSeQC. BAM files were processed using cufflinks pipeline. Overall design: The project aims to assess the differential gene expression at E15.5 between the outflow tracts of Gata4 G295S mutant embryos and wildtype littermate controls.

Description
The circadian clock in mammalian cells is cell-autonomously generated during the cellular differentiation process, but the underlying mechanisms are not understood. Here we show that perturbation of transcriptional program by constitutive expression of c-Myc and Dnmt1 ablation disrupts the differentiation-coupled emergence of the clock from mouse embryonic stem cells (ESCs). Using these model ESCs, 484 genes are identified by global gene expression analysis as correlating factors with differentiation-coupled circadian clock development. Among them, we find the misregulation of Kpna2 (Importin-alpha2) during the differentiation of the c-Myc over-expressed and Dnmt1-/- ESCs, in which sustaining cytoplasmic accumulation of PER proteins is observed. Moreover, constitutive expression of Kpna2 during the differentiation culture of ESCs significantly impairs clock development and KPNA2 facilitates cytoplasmic localization of PER1/2. These results suggest that the programmed gene expression network regulates the differentiation-coupled circadian clock development in mammalian cells, at least in part via post-transcriptional regulation of clock proteins. Overall design: Examination of whole transcriptome in ES cells and in vitro differentiated cells.

Description
Rett syndrome (RTT) is an X-linked dominant neurodevelopmental disorder caused by mutations in MECP2, encoding methyl-CpG binding protein 2. MeCP2 is a transcriptional repressor elevated in mature neurons and is predicted to be required for neuronal maturation by regulating multiple target genes. Identifying primary gene targets in either Mecp2-deficient mice or human RTT brain has proven to be difficult, perhaps because of the transient requirement for MeCP2 during neuronal maturation. In order to experimentally control the timing of MeCP2 expression and deficiency during neuronal maturation, human SH-SY5Y cells undergoing mature neuronal differentiation were transfected with methylated MeCP2 oligonucleotide decoy to disrupt the binding of MeCP2 to endogenous targets. Genome-wide expression microarray analysis identified all four known members of the inhibitors of differentiation or inhibitors of DNA binding (ID1, ID2, ID3 and ID4) subfamily of helix-loop-helix (HLH) genes as novel neuronal targets of MeCP2. Chromatin immunoprecipitation analysis confirmed binding of MeCP2 near or within the promoters of ID1, ID2 and ID3, and quantitative RT-PCR confirmed increased expression of all four Id genes in Mecp2-deficient mouse brain. All four ID proteins were significantly increased in Mecp2-deficient mouse and human RTT brain using immunofluorescence and laser scanning cytometric analyses. Because of their involvement in cell differentiation and neural development, ID genes are ideal primary targets for MeCP2 regulation of neuronal maturation that may explain the molecular pathogenesis of RTT.

Description
Human T-cell leukemia virus type 1 (HTLV-1) encodes HTLV-1 bZIP factor (HBZ), which is thought to be crucial for neoplastic and inflammatory diseases caused by HTLV-1. So, we analyzed the transcriptional profile of HBZ expressing cells and how HBZ affect the expression of apoptosis-related genes.

- Affymetrix Rat Expression 230A Array (rae230a)
Description
We performed global scale microarray analysis to identify detailed mechanisms by which nonpermissive temperature induces cell growth arrest and differentiation in astrocyte RCG-12 cells harboring temperature-sensitive simian virus 40 large T-antigen by using an Affymetrix GeneChip system. Astrocyte RCG-12 cells used in this study were derived from primary cultured rat cortical glia cells infecting with a temperature-sensitive simian virus 40 large T-antigen. Although the cells grew continuously at the permissive temperature, the nonpermissive temperature led to cell growth arrest and differentiation. Of the 15,923 probe sets analyzed, nonpermissive temperature differentially expressed 556 probe sets by >2.0-fold.
