Project description:Orphan nuclear receptor chicken ovalbumin upstream promoter transcription factor 2 (COUPTF2; NR2F2) is highly expressed in endothelial cells (ECs) and Nr2f2 knockout produces lethal cardiovascular defects. In humans, NR2F2 mutations result in both congenital heart disease and diaphragmatic hernia, conditions associated with the development of pulmonary arterial hypertension (PAH). However, COUPTF2 functions in mature endothelium are uncertain. NR2F2 knockdown in primary human endothelial cells (ECs) led to an interferon-biased inflammatory response, endothelial-to-mesenchymal transition, proliferation, hypermigration, apoptosis-resistance and mitochondrial dysfunction. These phenotypic changes were associated with AKT activation and increased Dickkopf-1 (DKK1) expression, a Wnt/β-catenin pathway inhibitor. DKK1 was also elevated in patients with PAH and secreted in response to loss of bone morphogenetic receptor type 2 (BMPR2), the archetypal PAH-associated genetic defect. Together, these findings demonstrate that endothelial NR2F2 suppresses inflammation and proliferation. Thus, NR2F2 loss disrupts EC homeostasis and may promote pathologic vascular remodeling in the development of PAH.

Project description:Gene expression profiles of primary lymphatic endothelial cells (LECs) isolated from human foreskin were analyzed after siRNA-mediated knockdown of control (firefly luciferase), Prox1, NR2F2 or Prox1/NR2F2 for 48 hours. Experiment Overall Design: Passage five human lymphatic endothelial cells (LECs) were cultured on fibronectin (10 μg/ml)-coated plates in a complete media (EBM, 20% FBS supplemented with 10 μg/ml hydrocortisone acetate, 25 ug/ml cAMP and antibiotics). LECs were harvested and electorporated with siRNA duplexes for 48 hours with siRNA duplexes against either firefly luciferase(control), Prox1, NR2F2 or Prox1/NR2F2. Total RNA was purified using Tri-reagent and was subjected to microarray analysis. Experiment Overall Design:

Project description:The Alternative Lengthening of Telomeres (ALT) facilitates telomere lengthening by a DNA strand invasion and copying mechanism. The nuclear receptor NR2F2 can bind to (TCAGGG)n variant repeats within telomeres and it has been proposed that this facilitates telomere interactions in ALT+ cells. However, the role NR2F2 in regulation the gene expression in ALT+ cell lines is unclear. Here, using Next Generation Sequencing (NGS), we characterised the changes in expression profile of three ALT+ cell lines (W-V, WI38VA13/2RA, U2OS) upon transient siRNA mediated downregulation of NR2F2 compared to cells treated with a control siRNA . Among 86 ALT-associated genes, only MND1 showed consistent down-regulation across the three NR2F2-depleted ALT+ cell lines. Altogether our data indicate that NR2F2 it does not play a direct role in the ALT mechanism.
