Plants with decreased SWC4 expression levels displayed several pleiotropic phenotypic alterations, suggesting that this gene participates in the regulation of different developmental processes. To evaluate genes whose expression was misregulated in SCW4 RNAi line, we performed RNA-seq differential expression analysis.

View SamplesG protein-coupled receptor kinase 2 (GRK2) has emerged as a key regulator of cardiac function and myocardial structure. Cardiac GRK2 is increased in heart failure and ischemia in humans, whereas genetic inhibition of GRK2 is cardioprotective in animal models of these pathologies. However, the mechanistic basis underlying these effects are not fully understood. We have used adult GRK2 hemizygous mice (GRK2+/-) as a model to assess the effects of a sustained systemic inhibition of GRK2 in heart tissue with age.
Downregulation of G protein-coupled receptor kinase 2 levels enhances cardiac insulin sensitivity and switches on cardioprotective gene expression patterns.

View SamplesLeukemia cells are considered developmentally 'frozen', and their phenotype is thought to reflect their stage of origin. To gain insights into the cell population from which T-ALL arises, we compared by global gene expression profiling T-ALL samples (n = 10) to different stages of T cell development, following the order from early thymic progenitor (ETP), to triple negative (TN) TN2, to TN3, to TN4, to immature single positive (ISP), to double positive (DP) thymocytes.

View SamplesWild type thymi were transplanted into a competitive (wild type hosts), or non-competitive (Rag2-/-c-/-KitW/Wv hosts) environment. Triple negative 2 and 3 (TN2/3) stages were sorted 14 days afetr transplantation and separated for cells of host or donor origin.

View SamplesTranscriptome was assessed in the transitions from the normal thymus (with regular progenitor turnover), to a thymus devoid of extrinsic progenitor competition for 10 weeks, to fully malignant T cell acute lymphoblastic leukemia (T-ALL).

View SamplesIntestinal epithelisal cells were obtained by EDTA isolation of ileum from WT mice followed by facs sorting (EpCAM + CD45 – 7AAD – ). Raw sequencing reads were aligned to the mouse genome (mm10) with Tophat , and gene expression levels were measured by Cufflinks . Overall design: Ileum epithelisal cells mRNA profiles were generated by deep sequencing, in duplicate, using illumina HiSeq 2000.

View SamplesGene expression profiles of bipolar disorder (BD) patients were assessed during both a manic and a euthymic phase and compared both intra-individually, and with the gene expression profiles of controls.
Investigation of manic and euthymic episodes identifies state- and trait-specific gene expression and STAB1 as a new candidate gene for bipolar disorder.

View SamplesCNBP is a eukaryote-conserved nucleic-acid binding protein required in mammals for embryonic development. It contains seven CCHC-type zinc-finger domains and was suggested to act as a nucleic acid chaperone, as well as a transcription factor. Here, we identify all CNBP isoforms as cytoplasmic messenger RNA (mRNA)-binding proteins. Using Photoactivatable Ribonucleoside Enhanced Cross-linking and Immunoprecipitation, we mapped its binding sites on RNA at nucleotide-level resolution on a genome-wide scale and find that CNBP interacted with 3961 mRNAs in human cell lines, preferentially at a G-rich motif close to the AUG start codon on mature mRNAs. Loss- and gain-of-function analyses coupled with system-wide RNA and protein quantification revealed that CNBP did not affect RNA abundance, but rather promoted translation of its targets. This is consistent with an RNA chaperone function of CNBP helping to resolve secondary structures, thus promoting translation. Overall design: CNBP protein knockdown and RNA-seq
