RNAseq of Human Umbilical Vein Endothelial Cells treated with Insulin in the presence or absence of TGF-beta kinase inhibitor SB431542 for 90 minute.

ABSTRACT: Endothelial cells play many important role during development and development of diseases. Endothelial dysfunction which is commonly seen in diabetes patients is thought to be one of the first step that leads to adverse events such as retinopathy, nephropathy, and atherosclerosis. To examine to which extent TGF-beta signaling contributes to insulin-induced transcriptional responses we performed this RNAseq on Human umbilical vein endothelial cells.

NTRAS hnRNPL RNA sequencing in HUVECs

Project description:In the current project with aim to unequivocally characterize a novel splicing-regulatory network that proves to be a central mediator of endothelial barrier function and vascular integrity. At the core of this network is the endothelial enriched lncRNA NTRAS (annotated as RP11-354k1.1) is shown to control alternative splicing decisions in HUVECs through interplaying with splicing factor hnRNPL. Specifically, in the project we show that NTRAS sequesters the splicing factor hnRNPL through a CA dinucleotide motif, to enhance TJP1 exon 20 usage, thereby TJP1α+ isoform. In turn disrupting TJP1α+ isoform expression impaired endothelial barrier function. Collectively, this splicing-regulatory network might prove fundamental in unlocking new interventions strategic to prevent or reverse vascular leakage.

RNA-Seq analysis of Medicago truncatula hairy root lines treated with methyl jasmonate

Project description:In hairy roots of the model legume Medicago truncatula the saponin production can be elicited by methyl jasmonate treatment. To identify genes potentially involved in saponin biosynthesis or its regulation we carried out transcript profiling by RNA-Seq of M. truncatula hairy roots treated with 100 μM of methyl jasmonate (dissolved in ethanol) for two or 24 hours. As control, M. truncatula hairy roots treated with an equivalent amount of ethanol were profiled.

PHACTR1, a coronary artery disease risk gene, drives endothelial dysfunction

Project description:Recent genome-wide association studies have identified PHACTR1 as a critical risk gene associated with polyvascular diseases. However, it remains elusive how PHACTR1 is involved in endothelial dysfunction. Here, we show that PHACTR1 triggers endothelial inflammation by activating NF-κB and disrupts Nitric oxide production by inhibiting Akt/eNOS activation to induce endothelial diastolic disorder. Whereas, Atorvastatin particularly plays an inhibitory effect on PHACTR1 gene expression in a dose-dependent manner among PHACTR family in endothelial cells. PHACTR1 may interact with PP1 with coupling with heat shock protein 8 (HSPA8) to dephosphorylate Akt or eNOS.

Imprinting RNAseq

Project description:Long-term hematopoietic stem cells (HSCs), short-term HSCs and multipotent progenitor cells (MPPs) were isolated from bone marrow of four mouse strains (WT, H19-deletion, Igf1r-deletion, and double-deletion) and expression profiled with RNAseq. The behavior of the transcriptomes, and in particular the imprinted genes, was analyzed to see what might be involved in maintaining quiescence of long-term stem cells, and how H19 and Igf1r affected the expression of imprinted genes. Transcriptional profiling data of the same cells have been deposited in ArrayExpress under accession number E-MTAB-1644 (http://wwwdev.ebi.ac.uk/arrayexpress/experiments/E-MTAB-1644/).

Oxidative stress related long non-coding RNAs (lncRNAs) in human umbilical vein endothelial cells

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 qRTâPCR. 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.

Physiological Vascular Permeability Requires Induction of Endothelial NR4A1 by Progesterone Receptor [RNA-Seq]

Project description:Vascular permeability is frequently associated with inflammation and it is triggered by chemokines and by a cohort of secreted permeability factors, such as VEGF. In contrast, here we showed that the physiological vascular permeability that precedes implantation is directly controlled by progesterone receptor (PR) and it is independent of VEGF. Both global and endothelial-specific deletion of PR block physiological vascular permeability in the uterus while misexpression of PR in the endothelium of other organs results in ectopic vascular leakage. Integration of genome-wide transcriptional profile of endothelium and ChIP-sequencing revealed that PR induces a NR4A1 (Nur77/TR3) specific transcriptional program that broadly regulates vascular permeability in response to progesterone. This program triggers concurrent suppression of several junctional proteins and leads to an effective, timely and venule-specific regulation of vascular barrier function. Silencing NR4A1 blocks PR-mediated permeability responses indicating a direct link between PR and NR4A1. These results reveal a previously unknown function for progesterone receptor on endothelial cell biology with consequences to physiological vascular permeability and implications to the clinical use of progestins and anti-progestins on blood vessel integrity.

Genome-wide maps of H3K27ac localization in HUVECs

Project description:H3K27Ac is one of the expressed enhancer markers in endothelial cells, but its genomic localization is unknown. This time, we established a new antibody for H3K27ac, and performed ChIP-seq to identify H3K27ac binding site in whole genome manner under hypoxia. We used chromatin immunoprecipitation with deep sequencing (ChIP-seq) of HUVECs treated with or without hypoxia (1%O2) for 24hours, then H3K27ac binding regions were identified. Normoxia was used as a control condition. HUVECs were used within the first 6 passages.

Slit2 modifies VEGF-induced angiogenic responses in rabbit skeletal muscle by inducing capillary sprouting and decreasing vascular permeability via reduced eNOS activity

Project description:Rationale: Slit2 is a possible modulator of vascular endothelial growth factor (VEGF) - induced angiogenesis, but its effects have not been tested in large animal models. Objective: We studied the effect of Slit2 on therapeutic angiogenesis induced by VEGF receptor 2 (VEGFR2) ligands Vammin and VEGF-DΔNΔC in vivo in rabbit skeletal muscles. The Slit2 target genes were also studied by RNA sequencing (RNA-Seq) in endothelial cells. Methods and Results: Adenoviral intramuscular gene transfers were performed into rabbit hindlimbs. Confocal and multiphoton microscopy were used for blood vessel imaging. Signaling experiments and gene expression analyses were performed to study mechanisms of Slit2 action. Slit2 decreased VEGFR2-mediated vascular permeability. It also reduced VEGFR2-mediated increase in blood perfusion and capillary enlargement, whereas sprouting of the capillaries was increased. Slit2 gene transfer alone did not have any effects on vascular functions or morphology. VEGFR2 activation was not affected by Slit2, but eNOS phosphorylation was diminished. The transcriptome profiling showed Slit2 downregulating angiogenesis-related genes such as nuclear receptor subfamily 4 group A member 1 (NR4A1) and Stanniocalcin-1 (STC-1) as well as genes related to endothelial cell migration and vascular permeability. Conclusions: Combining Slit2 with VEGFs adjusts VEGFR2-mediated angiogenic effects into a more physiological direction. This possibly allows the use of higher VEGF vector doses to achieve a more widespread vector and VEGF distribution in the target tissues leading to a better therapeutic outcome while reducing excess vascular permeability.

Expression profiles of mRNAs and lncRNAs regulated by let-7e in vascular endothelial cells

Project description:Many studies have demonstrated miRNAs as key regulators of inflammatory responses in endothelial cells (Ecs). However, because of the complexity of inflammatory genes and miRNAs, there would be many undiscovered miRNAs involved in inflammatory responses of ECs. Let-7e is an important member of let-7e family and plays key roles in the regulation of inflammation and endothelial cell proliferation. Furthermore, let-7e expression is significantly increased in many cardiovascular diseases including coronary heart disease. Therefore,we speculated that let-7e might play important roles in the regulation of inflammatory responses in endothelial cells by directly or indirectly targeting certain inflammatory genes. In order to reveal the action of let-7e in vascular endothelial cells, the expression profiles of mRNAs and lncRNAs induced by let-7e in human umbilical vein endothelial cells (HUVECs) were investigated using microarray technology.

Genome-wide maps of RNA Polymerase II and p65 localization in HUVECs stimulated with TNF alpha

Project description:TNF alpha is one of the inflammatory mediator and induce genes mainly by transcriptional factor, p65, in endothelial cells. This time, we performed a time course study to detect the change of localization of p65 and Pol II. To identify p65 and Pol II binding sites, we used chromatin immunoprecipitation with deep sequencing (ChIP-seq) of HUVECs treated with or without TNF alpha for 30 mins. Cells were starved before stimulation longer than 16 hours. HUVECs were used within the first 6 passages. For crosslinking, 10 mM of EGS in 50% glacial acetic acid was used for 45 min, followed by 20 min of 1% paraformaldehyde treatmet was used.
