The gene expression of HUVEC in response to the cytokine stimulations
Ontology highlight
ABSTRACT: The response of endothelial cells to the tissue environment has a critical impact on their function in inflammation and tumors. In particular, cytokine stimulation such as TNFa, IL-4, IFNg, and LTbR induces gene expression changes, which significantly impact endothelial cell function and differentiation. To understand the degree of gene expression change, we performed a transcriptome analysis of HUVEC.
Project description:We report the use of bulk RNAseq of AML and endothelial cell lines in four conditions (1. Untreated; 2. IFNg - 10 ng/ml; 3. TNFa - 10 ng/ml; 4. IFNg and TNFa - 10 ng/ml) in order to identify genes that are differentially expressed between the two cell types, both at baseline and in an inflammatory microenvironment.
Project description:Human umbilical vein endothelial cells (HUVEC) were cultured in serum-free medium with 50 μmol/L ADMA (ADMA group) or without ADMA (NA group ). Asymmetric dimethylarginine is a typical uremic toxin which used to induce HUVEC injury.
Project description:Question Addresses: What is the gene expression profile from human umbilical vein endothelial cells (HUVEC) and human Jurkat T cells after irradiation (IR)? What, if any, is the effect of co-culturing these two cell types on gene expression? There are eight experimental conditions for this experiment: (1) non-irradiated HUVEC; (2) irradiated HUVEC; (3) non-irradiated Jurkat; (4) irradiated Jurkat; (5) non-irradiated HUVEC + non-irradiated Jurkat+; (6) non-irradiated HUVEC + irradiated Jurkat; (7) irradiated HUVEC + non-irradiated Jurkat; (8) irradiated HUVEC + irradiated Jurkat. A common, pooled reference consisting of RNA taken from conditions 1-8 as described above was used for all hybridizations.
Project description:Analysis of umbilical vein endothelial cells (HUVEC) treated with Egr-3 siRNA under the VEGF treatment for 0,1, and 4 h. Egr-3, a member of early growth response family, is immediately and dramatically induced by VEGF in HUVEC, which regulates expression of many genes related to endothelial activation.
Project description:In the hematopoietic microenvironment, endothelial cells (ECs) play an important role in the regulation of hematopoietic cell proliferation and trafficking. We previously demonstrated that EC stimulated with tumor necrosis factor alpha (TNF-α) induce the generation of dendritic cells from CD34(+) stem cells, whereas in contrast, interleukins were capable of inducing the proliferation of hematopoietic and myeloid progenitors. In order to identify potentially new soluble factors which greatly impact the self-renewal, proliferation and differentiation of CD34+ hematopoietic stem cells (HSC), we examined the expression profiles of IL-1ß, IL-3 and IL-6 stimulated human umbilical vein endothelial cells (HUVEC).
Project description:We performed transcriptome analysis using DNA microarray in JPH203-treated HUVEC to elucidate endothelial cell response to LAT1 inhibition.
Project description:Whole transcriptome gene expression profiling of Normal -(HUVEC) Human Umbilical Vein Endothelial Cells The HUVEC gene expression results analyzed in this study are further described in Kustermann S. et al. (2014) A real-time impedance based screening assay for drug induced vascular leakage.
Project description:The many steps involved in the production of a mature mammalian mRNA are extensively coupled, and levels of both precursors and products can be measured using expression and genomic tiling microarrays. Different probes in these arrays targeting the same transcript often give different signals; then, precursor (nascent) RNA – which is present transiently at low concentrations – is difficult to detect.
