To define molecular events accompanying formation of the 3-dimensional (3D) vascular tube, we have characterized gene expression during vascular endothelial growth factor (VEGF)-induced tubular morphogenesis of endothelial cells. Microarray analyses were performed comparing gene induction in growth-arrested, tube-forming endothelial cells harvested from 3D(More)
Homogeneous assays based on real-time fluorescence monitoring during PCR are relevant alternatives for large-scale genotyping of single-nucleotide polymorphisms (SNPs). We compared the performance of the homogeneous TaqMan 5'-nuclease assay and the Molecular Beacon assay using three SNPs in the human estrogen receptor gene as targets. When analyzing a panel(More)
An in vitro model of VEGF-A-induced angiogenesis was used to generate transcription profiles of human microvascular endothelial cells. Microarray analysis showed increased transcription of genes known to regulate angiogenesis, but also genes that previously have not been firmly associated with angiogenesis such as endocan, pinin, plakophilin,(More)
Current methods widely deployed for colorectal cancers (CRC) screening lack the necessary sensitivity and specificity required for population-based early disease detection. Cancer-specific protein biomarkers are thought to be produced either by the tumor itself or other tissues in response to the presence of cancers or associated conditions. Equally, known(More)
Tetracycline-regulated gene expression systems are widely used to allow temporal and quantitative control of transgene expression in cultured cells and transgenic animals. While working with the Tet-Off system, where tetracycline or the analogue doxycycline suppresses expression, we noted a considerable variability in induced transgene expression after(More)
Angiogenesis is regulated by growth factors which activate tyrosine kinase receptors leading to the activation of a number of intracellular signaling pathways. The specific function of H-Ras during FGF-2 stimulated endothelial cell differentiation, defined as invasive growth and formation of branching networks in fibrin gels, was investigated by using(More)
