MicroRNA expression profile of human umbilical vein endothelial cells treated with Angiogenin (ANG)
ABSTRACT: We quantified differential microRNA (miRNA) expression in Human umbilical vein endothelial cells （HUVECs）response to Angiogenin (ANG) treatment.These data were used to determine which miRNAs are altered on ANG in Human umbilical vein endothelial cells. Overall design: Each group had a n=2 and ANG response miRNA levels post incubations were compared to no treatment with ANG.

Project description:Examine the toxic effect and molecular mechanisms of PM2.5 in primary human umbilical vein endothelial cells (HUVECs) . We used microarrays to detail the global programme of gene expression in HUVECs exposed to PM2.5 and identified distinct classes of up-regulated genes. Cultured HUVECs which were treated with PM2.5 at the concentrations of 50 μg/mL or DMEM for 24 h were collected for RNA extraction and hybridization on Affymetrix microarrays.
Project description:In order to identify new markers of vascular cell senescence with potential in vivo implications, primary cultured Human Umbilical Vein Endothelial Cells (HUVECs), were analysed for microRNA (miR) expression. QRT-PCR microRNA expression profiling in 3 senescent (XIII passage) vs. 3 young HUVECs (II passage).
Project description:Human umbilical vein endothelial cells (HUVECs) were incubated for 48 h under normoxic or hypoxic (1% oxygen) conditions. Changes in transcript and exon levels were analyzed. Overall design: 6 samples; 2 conditions: normoxia vs. hypoxia (1% oxygen); 3 replicates per condition

Project description:Long non-coding RNAs (lncRNAs) exhibit a poor interspecies conservation and often show spatial- and temporal-specific expression patterns. What, if any, role they have in oxidative stress remains unknown. To identify potential roles for lncRNAs, we examined their expression in normal and H2O2-treated human umbilical vein endothelial cells. Oxidative stress related lncRNAs were generated by deep sequencing, using Illumina HiSeq 2000 or 2500 platform. Sequencing of the cDNA libraries from H2O2-treated HUVECs generated 12.5 million uniquely valid reads, meanwhile, 10.2 million valid fragments were obtained from control group in our experiment. A total of 10, 765 known and 30, 629 novel putative lncRNAs were identified according to RNA-Seq. Among them, 2, 091 of known and 25, 800 of novel lncRNAs were differentially expressed in H2O2-treated HUVECs compared with control HUVECs, and 12 of these were validated with qRT–PCR. Taken together, our findings provide evidence differentially expressed lncRNAs were mediated by oxidative stress in HUVECs, it is, therefore, likely that aberrant expression of lncRNAs, at least in part, participate in the process of endothelial injury caused by oxidative stress.

Project description:Human umbilical vein endothelial cells (HUVECs) were incubated for 48 h after transfection of scrambled siRNA or siRNA targeting Jmjd6 . Changes in transcript and exon levels were analyzed. 6 samples; 2 conditions: Scrambled siRNA vs. siJmjd6 ; 3 replicates per condition
Project description:Human umbilical vein endothelial cells (HUVECs) were insulted with cobalt chloride to induce cell apoptosis and alternative splicing in the mimic-hypoxia environment. We use Affymetrix exon array to reveal differential expression from transcript-level and exon-level in genome-wide. Overall design: 6 samples, 2 conditions: mimic hypoxia and normoxia, 3 replicates per condition
Project description:Oxidoreductase enzymes are critical to redox regulation of intracellular proteins within human cells. We used microarrays to identify which oxidreducatse genes are expressed in unstimulated human umbilical vein endothelial cells. Overall design: Human umbilical vein endothelial cells were grown under optimal conditions and then RNA extracted and hybridized on Affymetrix microarrays.
Project description:Atheroprotective flow (e.g., pulsatile shear stress) and statins drastically induce the expression of krüppel-like factor 4 (KLF4) in vascular endothelial cells (ECs). We therefore investigated the role of KLF4 in EC function through comparing the transciptional profiling of human umbilical vein endothelial cells (HUVECs) that were infected with adenovirus overexpression KLF4 (Ad-KLF4) or with empty vector (Ad-null) control. Gene ontology analysis revealed that KLF4 not only regulates EC homeostasis through the upregulation of nitric oxide synthesis and vascular development, but also mediates response to lipid. Among the lipid responsive genes, KLF4 exhibited induction of cholesterol efflux and oxidation [i.e., liver X receptor (LXR) and cholesterol 25-hydroxylase (Ch25h)], while suppressing cholesterol biosynthesis [i.e., sterol regulatory element-binding protein 2 (SREBP2)]. Overall design: Transcriptome data of HUVECs overexpressing KLF4 using adenovirus followed by deep sequencing, in biological duplicate, using Illumina NextSeq 500.
