Choroid plexuses (CP) develop early during development. They form a barrier between the blood and the cerebrospinal fluid, and fulfill important protective and nutritive functions. We used Affymetrix microarrays to assess whether CP of the lateral ventricles (LVCP) have similar functions in developing and adult brain. We identified distinct families of protective and transport genes and found that most of these genes were already well expressed during development.

View SamplesWe used RNA sequencing to characterize gene expression of CD4+ CD8a+ double positive (DP), Foxp3+ Treg (TR) and CD4+ single positive (SP) cells in the lamina propria (LP) and intraepithelial compartment (IEL) that had differentiante from the same clonal transnuclear (TN) precursor. Overall design: We adoptively transferred CD4+ CD8a- Foxp3-GFP- isolated from pTregTN/RKO/Foxp3-GFP mice into TCRaßKO hosts. After 6 weeks, we sorted transferred CD4+ CD8a+, Foxp3+ pTreg as well as unconverted CD4+ CD8a- Foxp3-GFP- from the small intestine LP and IEL compartments for whole transcriptome analysis by mRNA sequencing.

View SamplesThe wheat gene Lr34 (Yr18/Pm38/Sr57/Ltn1) encodes a putative ABCG-type of transporter and is a unique source of disease resistance providing durable and partial resistance against multiple fungal pathogens. Lr34 has been found to be functional as a transgene in barley.
The wheat resistance gene Lr34 results in the constitutive induction of multiple defense pathways in transgenic barley.

View SamplesHuman ILCs are classically categorized into five subsets; cytotoxic CD127-CD94+ NK cells and non-cytotoxic CD127+CD94-, ILC1s, ILC2s, ILC3s and LTi cells. Here, we identify a novel subset within the CD127+ ILC population, characterized by the expression of the cytotoxic marker CD94. These CD94+ ILCs strongly resemble conventional ILC3s in terms of phenotype, transcriptome and cytokine production, but are highly cytotoxic. IL-15 was unable to induce differentiation of CD94+ ILCs towards mature NK cells. Instead, CD94+ ILCs retained RORγt, CD127 and CD200R expression and produced IL-22 in response to IL-15. Culturing non-cytotoxic CD127+ ILC1s or ILC3s with IL-12 induced upregulation of CD94 and cytotoxic activity, effects that were not observed with IL-15 stimulation. Thus, human helper ILCs can acquire a cytotoxic program without differentiating into NK cells.

View SamplesWe performed transcriptome analysis of Human Aortic Endothelial Cells after siRNA mediated knockdown of MTHFD2. We identified MTHFD2 as a key driver for a gene cluster which integrates mitochondrial one-carbon metabolism, serine synthesizing enzymes as well as common amino acid and ER stress response genes. Overall design: Human Aortic Endothelial Cells were treated with three different siRNAs against MTHFD2 or scramble for 72 h
Oxidized phospholipids regulate amino acid metabolism through MTHFD2 to facilitate nucleotide release in endothelial cells.

View SamplesTranscriptional dysregulation is an early feature of Huntington''s disease (HD). We observed gene-specific changes in H3K4me3 at transcriptionally repressed promoters in R6/2 mouse and human HD brain. Genome-wide analysis showed a novel chromatin signature for this mark. Reducing the levels of the H3K4 demethylase SMCX/Jarid1c in primary neurons reversed down-regulation of key neuronal genes caused by mutant Huntingtin (Htt) expression. Finally, reduction of SMCX/Jarid1c in primary neurons from BACHD mice or the single Jarid1 in a Drosophila HD model was protective. Therefore, targeting this epigenetic signature may be an effective strategy to ameliorate the consequences of HD. Overall design: mRNA-seq in wild type and R6/2 cortex and striatum at 8 and 12 weeks.

View SamplesMiRNAs are discussed as diagnostic and therapeutic molecules. However, effective miRNA drug treatments with miRNAs are so far hampered by the complexity of the miRNA networks. To identify potential miRNA drugs in colorectal cancer, we profiled miRNA and mRNA expression in matching normal, tumor and metastasis tissues of eight patients by Illumina sequencing. We identified miRNA-1 as top candidate differentially expressed in tumor and metastasis. Furthermore, miRNA-1 was de-regulated in 16 additional tumor entities underscoring its central role in tumor pathogenesis. Functional analyses showed an additive effect of miRNA-1 with camptothecin treatment. We used a systems-biology simulation of cellular cancer models implemented in PyBios to investigate miRNA-1 function and assessed the effects of depletion as well as overexpression in terms of miRNA-1 as a potential treatment option. In this system miRNA-1 treatment reverted the disease phenotype with different effectiveness among the patients. Scoring the gene expression changes obtained through mRNA-Seq from the same patients we show that the combination of deep sequencing and systems biological modeling can help to identify patient-specific responses to miRNA treatments. We present this data as guideline for future pre-clinical assessments of new and personalized therapeutic options. Overall design: Examination of miRNA expression values by Illumina sequencing of matched benign, tumor and metastasis tissues of 8 colorectal cancer patients. For 4 of these patients all tissues have been resequenced to obtain mRNA expression values.
