NMuMG is an epithelial cell line that can be induced into EMT by TGF- treatment or MET by TGF- withdrawl. During EMT, several marker genes were downregulated/upregulated, which is consistent with its mesenchymal phenotype.

View SamplesIMP3 (IGF2-mRNA binding protein 3) is a member of a family of IGF2-mRNA binding proteins that function in RNA stabilization, trafficking and localization. It exhibits the properties of an oncofetal protein and its expression correlates with the aggressive behavior of many tumors. In breast cancer, IMP3 is associated with the highly aggressive triple-negative subtype (TNBC) The challenge is to identify specific proteins and functions that are regulated by IMP3. As an approach to this problem, we compared the mRNA expression profile of SUM-1315 cells, a TNBC cell line, to the same cells that had been depleted of IMP3. Overall design: SUM-1315 breast cancer cells were were infected with lentivirus for control shRNA and two different IMP3 shRNAs and processed for RNA-sequencing

View SamplesMicroarrays have been widely used for the analysis of gene expression and several commercial platforms are available. The combined use of multiple platforms can overcome the inherent biases of each approach, and may represent an alternative that is complementary to RT-PCR for identification of the more robust changes in gene expression profiles.

View SamplesThe improvement of Ewing's sarcoma (EWS) therapy is currently linked to find strategies to select patients with poor and good prognosis at diagnosis and to generate modified treatment regimens. In this study, we analyze the molecular factors governing EWS response to chemotherapy in order to identify genetic signatures that may be used for risk-adapted therapy.

View SamplesThe Gata4 transcription factor is essential for normal heart development, but the molecular basis for its function remain poorly understood. We profiled at the whole genome level transcript changes in cardiomyocytes when Gata4 is depleted from zebrafish embryos. Our objective was to elucidate the cardiomyocyte-specific molecular program functioning downstream of Gata4 in order to better understand the role of Gata4 in cardiac morphogenesis. Overall design: Six samples in total are deposited. Three replicate control samples and three replicate Gata4 morphant samples were analyzed.

View SamplesAlbeit increased serum CK level and abnormal muscle histology are always present, boys with DMD are phenotipically indistinguishable from the normal ones at birth and, in their first years of life, acquire early motor milestones at normal times. A clear defect in muscle function becomes generally apparent by the end of the second year. As the disease is typically diagnosed between the ages of 3 and 7, the first two years are often considered and referred to as clinically presymptomatic.

View SamplesRenin, a key component in the regulation of blood pressure in mammals, is produced by the rare and highly specialized juxtaglomerular (JG) cells of the kidney. Although these cells line the media of the glomerular afferent arterioles and share some characteristics with contractile cells, they are filled with lysosome-like organelles where renin is activated and stored for regulated secretion in response to physiological and pathophysiological stimuli. Chronic stimulation of renin release results in a recruitment of new JG cells by the seeming conversion of adjacent smooth muscle cells along the afferent arterioles. Because JG cells rapidly de-differentiate when removed from the kidney, their developmental origin and the mechanism that explains their phenotypic plasticity remain largely unclear. In an effort to overcome this limitation, we have performed RNA expression analysis on four human renin-producing tumors. The most highly expressed genes that were common between the reninomas were subsequently used for in situ hybridization in mouse kidney. Our results add 40 new genes to the list that characterize renin-producing cells and reveal a significant variation in the expression patterns of developing, mature and recruited JG cells. Overall design: RNA-Seq was performed with a HiSeq 2000 on three biopsies of a first reninoma from Paris (Par1B1-B3), one biopsy from a reninoma from Montreal (Mon), two biopsies from a reninoma from Rotterdam (RotB1, B2), and a second reninoma from Paris (Par2) along with a biopsy from adjacent supposedly normal tissue from the same patient (Par2N).

View SamplesThe E-protein transcription factors E2A and HEB play important roles at several stages of hematopoiesis. However, the exact mechanism for theire action and the main targets in the LY6D negative common lymphoid progentior (CLP) compartment remains unknown. By adressing this question, we will gain important infromation regarding the early events leading to B-cell specification.
The transcription factors E2A and HEB act in concert to induce the expression of FOXO1 in the common lymphoid progenitor.

View SamplesHematopoietic stem cells (HSC) continuously regenerate a complete hematologic and immune system. Very few genes that regulate this process have yet been identified. In order to identify factors governing differentiation, we have compared the transcriptome of highly purified HSC with their differentiated progeny, including erythrocytes, granulocytes, monocytes, NK cells, activated and nave T-cells, and B-cells. Chromosomal analysis revealed that HSC were more transcriptionally active than other cell types across most chromosomes. Each lineage expressed ~100 to 400 genes uniquely, including many previously uncharacterized genes. Overexpression of two fingerprint genes resulted in a significant bias in differentiation indicating a role in cell fate determination, demonstrating the utility of these data for modulation of specific cell types.
