AIM: To detect differences in transcriptional profiles after knocking down Brca1, Bard1 or Wdr5, compared to a negative control in early reprogramming to pluripotency. DESCRIPTION: RNA-seq profiles of early reprogramming mouse embryonic fibroblasts (MEFs) transduced with lentivirus containing doxycycline-inducible OSKM factors to induce pluripotency . Before starting reprogramming, OSKM-MEFs were transfected with different siRNAs and then they were reprogrammed for 3 or 6 days. Overall design: The control sample consists of cells transfected with non-targeting siRNA. The other samples were transfected with either siBrca1, siWdr5 or siBard1. For every knockdown there is a biological replicate.
The corepressor NCOR1 and OCT4 facilitate early reprogramming by suppressing fibroblast gene expression.

View SamplesAIM: To find molecular signatures associated to the siRNA-mediated knockdowns in order to be able to identify similarities among different knockdowns. DESCRIPTION: Each sample includes biological triplicates for 35 siRNA-mediated knockdowns targeting 30 chromatin-associated proteins during in early reprogramming to iPS at day 6. A daily timecourse from reprogramming cells, without treatment from MEFs until day 6 is also included in triplicate. Overall design: RNA was harvested for all samples in bulk and the CELSeq2 method was used to prepare the RNAseq libraries

View SamplesDifferent types of hair follicles can be found in the skin of mice. It is believed that the signals that control hair follicle differentiation arise from cells in a structure called the dermal papilla. Understanding the nature of those signals is of interest for the biology of the normal tissue.
Sox2-positive dermal papilla cells specify hair follicle type in mammalian epidermis.

View SamplesUsing measles virus induced T cell suppression as a model, we established that T cell inhibitory protein isoforms can be produced from alternatively spliced pre-mRNAs as a result of virus-mediated ablation of T cell receptor dependent activation of the phosphatidylinositol-3-kinase (PI3K). To asses production of alternative splice variants in response to PI3K abrogation in T cells at a whole cell level, we performed a Human Exon 1.0 ST Array on RNAs isolated from T cells stimulated only or stimulated after PI3K inhibition. We developed a simple algorithm based on a splicing index to detect genes that undergo alternative splicing (AS) or are differentially regulated (RG) on T cell suppression. Applying our algorithm on this model 9% of the genes were assigned as AS, while only 3% were attributed to RG. Though there are overlaps, AS and RG genes differed with regard to functional regulated at the level of AS or RG were found enriched in different functional groups with AS targeting e. g. extra cellular matrix (ECM)-receptor interaction and focal adhesion, while cytokine-receptor interaction, Jak-STAT and p53 pathways were mainly RG. When combined, AS/RG dependent alterations targeted pathways essential for T cell receptor signaling, cytoskeletal dynamics and cell cycle entry strongly supporting the notion that PI3K abrogations interferes with key T cell activation processes at both levels, and that candidates represented within both categories bear the potential to actively contribute to T cell suppression

View SamplesThe overall aim of the present work was to identify MTG16 functions in leukemia cells. Alterations in quantity of the MTG16 co-repressor might affect gene regulation and cell metabolism in malignant cells. Differentiated cells secure energy for cellular homeostasis largely by mitochondrial oxidation. Whereas, mature cells, proliferating tumour cells including leukemia cells depend on glycolysis and mitochondrial respiration may be low even in oxygenrich environments.The same signal transduction pathways that govern cell proliferation give instructions for nutrient uptake and co-regulate metabolic processes. In this manner, the metabolism of tumor cells, and other highly proliferating cells, is adapted to stimulate anabolic glycolysisdriven processes for incorporation of nutrients into nucleotides, amino acids and lipids to synthesize macromolecules required for growth and proliferation.
The transcriptional co-repressor myeloid translocation gene 16 inhibits glycolysis and stimulates mitochondrial respiration.

View SamplesWe report the effects of silencing SRSF1 or ZMAT2 in human epidermal stem cells on the transcriptome of epidermal stem cells. We found that silencing ZMAT2 or SRSF1 affects global splicing, however, ZMAT2 seems to regulate splicing of a smaller more specific subset of genes. Overall design: RNA-sequencing data following silencing SRSF1 or ZMAT2

Antibiotics (n=11) or control saline (n=13) were given twice daily from birth to tissue collection at d 5. NEC-lesions and intestinal structure, function, microbiology and immunity markers were recorded.
Antibiotics modulate intestinal immunity and prevent necrotizing enterocolitis in preterm neonatal piglets.
