To analyze the role of DNA methylation during differentiation, we performed genome-wide expression analysis of undifferentiated wild type, dnmt1-/- and triple knock out (TKO; dnmt1-/-, dnmt3a-/-, dnmt3b-/-) ESCs as well as respective embryoid bodies (EBs) at two stages of differentiation
Global DNA hypomethylation prevents consolidation of differentiation programs and allows reversion to the embryonic stem cell state.

View SamplesThe goal of the study was to compare transcriptome changes in HeLa cells after infection with recombinant Thogoto virus (wild-type, ML deletioin mutant or ML SW mutant not able to interact wiith TFIIB. While wild-type virus is able to inhibit inflammatory genes, ML deletion mutant and TFIIB-non-interacting mutant lose this effect on gene transcription. Overall design: Examination of transcriptome changes in HeLa cells under steady state or after THOV infection using Illumina HiSeq.
Viral targeting of TFIIB impairs de novo polymerase II recruitment and affects antiviral immunity.

View SamplesBackground/aims: Serum concentrations of the hepatokine fibroblast growth factor (FGF) 21 are elevated in obesity, type2 diabetes, and the metabolic syndrome. We asked whether FGF21 levels differ between subjects with metabolically healthy vs. unhealthy obesity (MHO vs. MUHO) opening the possibility that FGF21 is a crosstalker between liver and adipose tissue in MUHO. Furthermore, we studied the effects of chronic FGF21 treatment on adipocyte differentiation, lipid storage, and adipokine secretion.
Fibroblast growth factor 21 is elevated in metabolically unhealthy obesity and affects lipid deposition, adipogenesis, and adipokine secretion of human abdominal subcutaneous adipocytes.

View SamplesWe study differences in gene expression between Populus P35S::BL (BL-oe) lines and control, affecting plant growth and differentiation, and dormancy. We used microarrays to detail the global program of gene expression underlying morphological and developmental changes droved by overexpression of BL gene.

View SamplesMicroRNAs (miRNAs) are small RNAs that play important regulatory roles in many cellular pathways. MiRNAs associate with members of the Argonaute (Ago) protein family and bind to partially complementary sequences on mRNAs and induce translational repression or mRNA decay. MiRNA expression can be controlled by transcription factors and can therefore be cell type- or tissue-specific. Here we have analyzed miRNA expression profiles in murine monocyte-derived dendritic cells (DCs) and macrophages upon stimulation with LPS, LDL, eLDL and oxLDL to identify not only stimuli-specific miRNA, but also to identify a hierarchical miRNA system involving miR-155. For this, miR-155 knockout dendritic cells and macrophages were also sequenced using the same stimuli. Overall design: Sequencing of murine monocyte-derived dendritic cells and macrophages (each wild type and miR-155 knock out cells) matured and stimulated, respectively, by LPS, oxLDL, eLDL or LDL.
