Project description:Comparison of transcriptional profiles of human umbilical vein endothelial cells (HUVECs) expressing wild-type vs. VM-causative mutant forms of TIE2/TEK. The effects of the most common Venous Malformation-causative mutations in the endothelial cell tyrosine kinase receptor: R849W and L914F, were tested. 743 genes were differentially expressed across the four groups. The 80 genes distinguishing between L914F and wild-type TIE2-expressing HUVECs were analyzed in greater detail. 3 batches each of: non-transfected, and wild-type TIE2, R849W-TIE2, and L914F-TIE2 overexpressing HUVECs were compared by exon-array profiling.

Project description:To identify the miRNA expressing profiles of TIE2 expressing Monocytes (TEMs), we have employed the Agilent Human miRNA 8×60K (Design ID:046064) microarray. Human peripheral blood mononuclear cells (PBMCs) in venous blood from healthy donors were isolated by Lymphoprep (Axis-Shield, Norway). Human monocytes in PBMCs, identified as cells that expressed CD14, were enriched by positive immunomagnetic selection using anti-CD14 MicroBeads (Miltenyi, Germany). TEMs (TIE2+CD14+) and TIE2-Monocytes (Tie2-CD14+) were then isolated by FACS-sorting (Aria II, BD Biosciences) using FITC-conjugated anti-CD14 (BD Biosciences, USA) and APC-conjugated anti-TIE2 (R&D System, USA) antibodies.Three TEMs samples together with their paried TIE2-Monocytes were detected.

Project description:To identify the gene expressing profiles of TIE2 expressing Monocytes(TEMs), we have employed the Agilent lncRNA Gene Expression 4Ã180K(Design ID:042818) microarray. Human peripheral blood mononuclear cells (PBMCs) in venous blood from healthy donors were isolated by Lymphoprep (Axis-Shield, Norway). Human monocytes in PBMCs, identified as cells that expressed CD14, were enriched by positive immunomagnetic selection using anti-CD14 MicroBeads (Miltenyi, Germany).

The gene expressions of three independent paried TEMs and TIE2- Monocytes samples from different donors were measured.

Project description:The ang1-Tie2 pathway is required for normal vascular development, but its molecular effectors are not well-defined during cardiac ontogeny. Here we show that endocardial specific attenuation of Tie2 results in mid-gestation lethality due to heart defects associated with a hyperplastic but simplified trabecular meshwork (fewer but thicker trabeculae). Reduced proliferation and production of endocardial cells (ECs) following endocardial loss of Tie2 results in decreased endocardial sprouting required for trabecular assembly and extension. The hyperplastic trabeculae result from enhanced proliferation of trabecular cardiomyocyte (CMs), which is associated with upregulation of Bmp10, increased retinoic acid (RA) signaling, and Erk1/2 hyperphosphorylation in the myocardium. Intriguingly, myocardial phenotypes in Tie2-cko hearts could be partially rescued by inhibiting in utero RA signaling with pan-retinoic acid receptor antagonist BMS493. These findings reveal two complimentary functions of endocardial Tie2 during ventricular chamber formation: ensuring normal trabeculation by supporting EC proliferation and sprouting, and preventing hypertrabeculation via suppression of RA signaling in trabecular CMs.
