Project description:Porcine aortic and aortic valve endothelial cells were exposed to 20 dynes/cm2 steady laminar shear stress with static cultures serving as controls. Total RNA was hybridized to Agilent Human 1 cDNA arrays and processed using the Agilent Feature Extraction Software Keywords = aortic valve Keywords = endothelial Keywords = shear stress Keywords: other
Project description:The experiment was designed to look at the effect (on gene expression) of exposing human cerebromicrovascular endothelial cell line hCMEC/D3 to propionate (3 micromolar) for 24 h, to determine if circulating metabolites have the potential to affect integrity of the blood-brain barrier.
Project description:Transcriptional profiling of NTG-treated E. coli imp fabI(G93V) cells compared to control cells (E. coli imp fabI(G93V) ) in the absence or presence of sub-lethal concentration of triclosan.
Project description:Analysis of primary bovine aortic endothelial cells treated for 24 hours with TGF-beta 1 5 ng/ml. TGF-beta 1 has been shown to induce endothelial-to-mesenchymal transition (EndoMT) and to be implicated in differentiation of endothelial cells into smooth muscle-like cells as occurred in vascular neointimal formation. Primary aortic endothelial cells seeded on 10 mm diameter plates were incubated with TGF-beta 1 (5 ng/ml) for 24 hours or left under basal conditions. Triplicates from three different cultures.
Project description:Gene expression changes in subconfluent mouse aortic endothelial cells were compared with confluent endothelial cells. Compartmental analysis showed coordinater response in several endothelial-specific functions and organelles (endoplasmic reticulum, Golgi, lysosomes, peroxisomes) which were downregulated, and upregulation of the microtubular system and proliferation. Keywords = endothelium Keywords = confluent Keywords = subconfluent Keywords = organelles Keywords: other
Project description:SAGE libraries were prepared from mRNA of cultured bovine glomerular and aortic endothelial cells. Cells both cell lines were positive for acetylated LDL uptake and vWF expression, and were proven to be free of non-endothelial cells. Cultures were studied at passage 9-10. The cells were confluent, cultured in parallel, under identical conditions. Cells were plated on gelatin coated cell culture plastic in RPMI 1640 medium containing 10% FBS and streptomycin/penicillin. The last medium change was 48 hours prior to mRNA harvest.

Project description:This is a pilot SILAC study wherein bovine aortic endothelial cells in culture were treated with the oxidant peroxynitrite, and compared to a control condition that consisted of reverse addition generated from peroxynitrite that underwent complete decomposition prior to mixing with cells. The study targets the protein cytochrome c, and hence, the results were confined to a search of all proteins under 45 kDa. The goal of this pilot study were to:
1) Identify the presence of cytochrome c in nuclear and cytosolic fractions
2) Identify amino acid residues in cytochrome c presenting post-translational modifications, such as tyrosine nitration or methionine oxidation
Project description:The variations in the protein profile of aortic-valvular (AVE) and endocardial endothelial (EE) cells are currently unknown. The current study's objective is to identify differentially expressed proteins and associated pathways in both endothelial cells. We used endothelial cells isolated from the porcine aortic valve and endocardium for the profiling of proteins. Label-free proteomics was performed by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Our proteomics analysis revealed that 29 proteins were highly expressed, and 25 proteins were less represented in the valve than endocardial endothelium. The first part of the study was already available in the ProteomeXchange Consortium (PXD009194).
