RNA-seq of human umbilical vein endothelial cells (HUVECs) stimulated with recombinant Vascular Endothelial Growth Factor A (VEGF-A) against untreated control

ABSTRACT: In order to identify new genes potentially involved in angiogenesis process, we performed a deep-sequencing transcriptome analysis of HUVECs stimulated with recombinant VEGF-A, introducing a difference with respect to the several previous studies. Primary ECs are normally cultured in vitro using an endothelial growth medium (EGM) constituted by an endothelial basal medium (EBM) supplemented with 2% fetal bovine serum (FBS) and a mix of growth factors and reagents, typically represented by basic Fibroblast Growth Factor (bFGF), Insulin-like Growth Factor 1 (IGF1), Epidermal Growth Factor (EGF), heparin, hydrocortisone, ascorbic acid and the same VEGF-A. In previous studies, HUVECs or other primary ECs were starved in EBM with low FBS concentration before the stimulation with VEGF-A. Instead of starvation, we grown HUVECs in complete EGM-2 medium except for VEGF-A to maintain the best condition for in vitro survival and propagation of primary ECs. After 24 hours of VEGF-A deprivation, VEGF-A was re-added to the medium and the stimulation was performed for six hours.

Transcription profiling of human umbilical vein endothelial cells (HUVEC) treated with VEGF-A

Project description:Angiogenesis, the formation of new capillaries by sprouting from preexisting vessels, is mainly induced by VEGF-A. To identify genes which are induced by VEGF-A in endothelial cells, HUVEC were starved and induced by VEGF-A165 for 30, 60 and 150min. RNA of induced and uninduced cells was isolated and subjected to microarray analysis using Affymetrix microarray. Experiment Overall Design: Human umbilical vein endothelial cells were grown in complete EGM-2 medium in dense culture for four days without change of medium and before the stimulation in EGM-2 medium without growth factors over night. The cells were stimulated with 100ng/ml VEGF-A165 for 30, 60 and 150 min. RNA was isolated with Trizol according to the manufacturer's instructions.

Expression data from human umbilical vein endothelial cells (HUVECs) as a function of cell adhesion and VEGF exposure

Project description:Angiogenesis is tightly regulated by both soluble growth factors and cellular interactions with the extracellular matrix (ECM). While cell adhesion via integrins has been shown to be required for growth factor signaling and downstream angiogenesis, the effects of quantitative changes in cell adhesion and spreading against the ECM remain less clear. Examining changes in global gene expression in limited versus high adhesion contexts in human umbilical vein endothelial cells, we demonstrated a VEGF-induced upregulation of genes associated with vascular invasion and remodeling when cell adhesion was restricted, whereas cells on highly adhesive surfaces upregulated genes associated with a proliferative response. HUVECs were cultured on micropatterned islands of fibronectin or allowed to spread fully for 2 hrs and then stimulated with 50ng/ml VEGF or no growth factor for 18 hrs in starve media. Sample RNA from three biological replicates was extracted and prepared for hybridization on Affymetrix microarrays.

M Costa endothelial diff protocol

Project description:To test our hypothesis that human embryonic stem cell-derived endothelial cells(hESC-ECs) represent their in vivo counterparts, we performed transcriptional profiling experiments in which we compared the gene expression profiles of d6 CD34+KDR+ cells, d12-14 hESC-ECs and human umbilical vein endothelial cells(HUVECs). Significantly upregulated genes were identified using significance analysis of microarrays (SAM), by comparing each of these populations to undifferentiated hESCs. Differentially regulated genes from each of these populations were examined using overlap analysis;to identify which genes are uniquely expressed in each cell type and which are expressed in common, followed by functional annotation clustering of the conserved core group of genes.

Gene array analysis of Human Umbilical Vein Endothelial Cells (HUVEC) transduced with lentivirus containing cDNA of NKX2,5 or GATA4 or GFP.

Project description:The aim of this study was to induce cardiomyogenic conversion of Human Umbilical Vein Endothelial Cells (HUVEC ) by triggering ectopic expression of the cardiac transcription factors Nkx2.5 and GATA4. Cells were cultured without cell myocardial co-culture system and transduced with lentivirus containing coding sequence of Nkx2.5, GATA4 or GFP as control. Cells were cultured in the EBM-2/ EGM-2 medium, 12 days before microarray analysis. We report in this study that over-expression of NKX2.5 and GATA4 in HUVECs stimulates the expression of some specific genes important in the cardiomyogenic differentiation process, leading to partial switch of these cells from the endothelial to the myocardial course. 12 arrays were analysed. Three competitive hybridizations to the arrays were performed in duplicate using each time, two dye-swap following this experimental design: AWA065 : CY5 (HUVEC+NKX2,5) / CY3 (HUVEC) AWA067 : CY5 (HUVEC) / CY3 (HUVEC+NKX2,5) AWA075 : CY5 (HUVEC+NKX2,5) / CY3 (HUVEC) AWA076 : CY5 (HUVEC) / CY3 (HUVEC+NKX2,5) AWA068 : CY5 ((HUVEC) / CY3 (HUVEC+GATA4) AWA070 : CY5 (HUVEC+GATA4) / CY3 ((HUVEC) AWA073 : CY5 (HUVEC+GATA4) / CY3 ((HUVEC) AWA002 : CY5 ((HUVEC) / CY3 (HUVEC+GATA4) AWA066 : CY5 (HUVEC) / CY3 (HUVEC+NKX2.5+GATA4) AWA069 : CY5 (HUVEC+NKX2.5+GATA4) / CY3 (HUVEC) AWA071 : CY5 (HUVEC+NKX2.5+GATA4) / CY3 (HUVEC) AWA074 ; CY5 (HUVEC) / CY3 (HUVEC+NKX2.5+GATA4)

Gene expression profiling of endothelial cells derived from Foxo1(+/+) and Foxo1(-/-) ES cells in response to VEGF

Project description:VEGF induces elongation of endothelial cells (ECs) that are derived from wild-type (Foxo1(+/+)) ES cells. VEGF-induced EC elongation is an important process of angiogenesis. ECs derived from Foxo1(-/-) ES cells fail to elongate in response to VEGF. Gene expression profiling of wild-type and Foxo1(-/-) ECs in the presence or absence of VEGF stimulation identifies responsible genes that regulate EC elongation. One wild-type (Foxo1(+/+)) ES cell clone and one Foxo1(-/-) ES cell clone were used. ES cells were cultured on OP9 stromal cell layer in the presence or absence of VEGF (10 ng/ml). After 6.5 days, VE-cadherin+ CD31+ ECs were isolated by FACS and used for total RNA extraction. Three independent experiments were performed for each condition.

Global analysis of NFATc1 targets in human vascular endothelial cells

Project description:We performed the newly mapping of genome-wide NFATc1 binding events in VEGF-stimulated primary cultured endothelial cells, by chromatin immunoprecipitation followed by high-throughput sequencing (ChIP-seq). Combined NFATc1 ChIP-seq profile and the epigenetic histone marks revealed that predominant NFATc1-occupied peaks were overlapped with promoter marking but not silencer marking. DNA microarrays with NFATc1 expression or knockdown indicated the predominant NFATc1 binding targets were correlated with induced patterns. To determine NFATc1-regulated genes, a total of 5 samples were derived from human umbilical vein endothelial cells (HUVECs) stimulated with or without 50ng/mL VEGF (VEGF 60min and 0min, respectively), pretreated with cyclosporine A (VEGF 60min plus CsA) and infected with adenovirus expressing the control or constitutively active NFATc1 (Ad-control and Ad-NFATc1).

The genome expression profile of human umbilical vein endothelial cells (HUVECs) overexpressing miR-146a

Project description:Endothelial cells are critical for angiogenesis, and microRNAs plays important roles in this process. We investigated the regulatory role of microRNAs in endothelial cells of hepatocellular carcinoma (HCC) by examining the microRNA expression profile of human umbilical vein endothelial cells (HUVECs) in the absence or presence of human HCC cells, and identified miR-146a as the most highly up-regulated microRNA. Furthermore, we revealed that miR-146a promoted the expression of platelet-derived growth factor receptor (PDGFRA) in HUVECs, and this process was mediated by BRCA1. Overexpression of PDGFRA in the ECs of HCC tissues was associated with microvascular invasion, and predicted a poorer prognosis. These results suggest that MiR-146a plays a key role in regulating the angiogenic activity of ECs in HCC through miR-146a-BRCA1-PDGFRA pathway. MiR-146a may emerge as a potential anti-angiogenic target on ECs for HCC therapy. We have employed whole genome OneArray to examine the genome expression changes of HUVECs overexpressing miR-146a.
