Gene expression in human endothelial cell with innate immunity stimulation

ABSTRACT: This is an investigation of whole genome gene expression level in human coronary endothelial cells (HCAEC) and human pulmonary endothelial cells (HPAEC) stimulated by FK565 or LipidA. We show that parenteral administration of a pure synthetic Nod1 ligand, FK565, induces site-specific vascular inflammation in mice, which is prominent in and aortic root including aortic valves, slight in aorta and absent in other arteries. The in vitro production of proinflammatory chemokine/cytokine by FK565 is higher in HCAEC than in HPAEC, suggesting that site-specific vascular inflammation is at least in part ascribed to an intrinsic nature of the vascular cell itself. A six chip study using total RNA recovered from HCAEC and HPAEC which were stimulated by LipidA or FK565 in vitro. HCAEC and HPAEC were stimulated with FK565 (10µg/mL) or LipidA (100ng/mL) for 24 hours in 12-well plates (10,000 cells/cm2). Total RNA was extracted and subjected to RNA microarray analysis.

Gene expression in tissues of Mus musculus with innate immunity stimulation

Project description:This is an investigation of whole genome gene expression level in tissues of mice stimulated by LPS, FK565 or LPS + FK565 in vivo and ex vivo. We show that parenteral administration of a pure synthetic Nod1 ligand, FK565, induces site-specific vascular inflammation in mice, which is prominent in aortic root including aortic valves, slight in aorta and absent in other arteries. The degree of respective vascular inflammation is associated with persistent high expression of proinflammatory chemokine/cytokine genes in each tissue in vivo by microarray analysis, and not with Nod1 expression levels. The ex vivo production of proinflammatory chemokine/cytokine by Nod1 ligand is higher in aortic root than in other arteries from normal murine vascular tissues, and also higher in human coronary artery endothelial cells (HCAEC) than in human pulmonary artery endothelial cells (HPAEC), suggesting that site-specific vascular inflammation is at least in part ascribed to an intrinsic nature of the vascular tissue/cell itself. A fourty chip study using total RNA recovered from four isolated tissues of mice which were stimulated by various reagents. Aortic root, pulmonary artery, aorta and spleen of mice in 3 groups: 1) intraperitoneal injection of 20M-NM-<g of LPS priming only, 2) oral administration of FK565 (100M-NM-<g) for consecutive days, 3) oral administration of FK565 (100M-NM-<g) for consecutive days 1 day after LPS priming, at day 2, 4, and 7. And six chip study using total RNA recovered from three isolated vascular tissues of mice which were stimulated by FK565 (10M-NM-<g/mL) ex vivo.

Expression profiling of Endothelial (EC) and Non-endothelial Cells

Project description:Gene expression profiling of HUVEC (human umbilical vein EC cell; Lonza), HAEC (human aortic EC cells), HCAEC (human coronary artery EC cells), HPAEC (human pulmonary artery EC cells), HMVEC (human microvascular (dermal) , HASMC ( Human Aortic Smooth Muscle Cells), T cells and Bcells. Gene expression profiling of Endothelial cells and Non-endothelial cells in order to identify the genes with preferntial expression to endothelial cells. The experiments are performed in duplicate on both the HT Human Genome U133A and U133B arrays.

Streptococcus agalactiae induced gene expression in human coronar artery endothelial cells

Project description:Early onset sepsis due to Group B streptococcus (GBS) leads to neonatal morbidity, increased mortality and long term neurological deficencies. Interaction between septicemic GBS and confluent monlayers of human coronary artery endothelial cells (HCAEC) was analyzed by a genome wide expression profiling. Regulation of selected genes and proteins identified in the gene array analysis was confirmed by Real Time RT-PCR assay (Granulocyte chemotactic protein 2 (CXCL6)), ELISA (Urokinase, Cyclooxygenase 2 (COX2), Granulocyte chemotactic protein 1 (IL8)) and Western Blotting (Heme oxygenase1, BCL2 interacting protein (BIM)) at various time points between 4 and 24 hours. In total, 124 genes were differentially regulated (89 upregulated, 35 downregulated) based on a more than 3-fold difference to unstimulated HCAEC. Regulated genes are involved in apoptosis, hemostasis, oxidative stress response, infection and inflammation. We confirmed upregulation of urokinase (UPA), COX2, HMOX1 and BCL2 interacting protein and downregulation of CXCL6 and IL8. These results indicate that GBS infection might lead to impaired function of the innate immune system and might contribute to hemorrhagic and inflammatory complications during GBS sepsis.

Physiological profile of the coronary artery and internal thoracic artery endothelial cells as a basis for the structural and functional congrunce of the arterio-arterial continuum

Project description:Currently, it is well established that human endothelial cells (ECs) are characterised by a significant heterogeneity between distinct blood vessels, e.g., arteries, veins, capillaries, and lymphatic vessels. Further, even ECs belonging to the same lineage but grown under different flow patterns (e.g., laminar and oscillatory or turbulent flow) ostensibly have distinct molecular profiles defining their physiological behaviour. Human coronary artery endothelial cells (HCAEC) and human internal thoracic artery endothelial cells (HITAEC) represent two cell lines inhabiting atheroprone and atheroresistant blood vessels (coronary artery and internal thoracic artery, respectively). Resistance of the internal mammary artery to atherosclerosis has been largely attributed to the protective phenotype of HITAEC which reportedly produce higher amounts of vasodilators including nitric oxide (NO) through the respective signaling pathways. However, this hypothesis has not been adequately addressed hitherto as proteomic profiling of HCAEC and HITAEC in a head-to-head comparison setting has not been performed.

PML regulates NF-ÎºB phosphorylation and transcriptional activity

Project description:The transcription factor NF-ÎºB is considered the master regulator of the immune response but also acts broadly to regulate gene expression that influences cell survival, proliferation and differentiation. Post-translational modification of NF-ÎºB, phosphorylation in particular, is essential for the transactivation activity of NF-ÎºB. Emerging evidence suggests that the regulation of NF-ÎºB in the nucleus is critical in controlling gene expression. Promyelocytic Leukemia (PML) is a nuclear protein that forms nuclear bodies (PML NBs), sub-nuclear structures that are associated with transcriptionally active genomic regions that have been implicated in multiple processes such as apoptosis, senescence and anti-viral responses. Chromosomal translocations leading to the expression of a PML-retinoic acid receptor-Î± (PML-RARÎ±) fusion protein are causative for acute promyelocytic leukemia (APL) characterised by a differentiation block at the promyelocytic state of myeloid development. Here we demonstrate that PML is required for phosphorylation of NF-ÎºB p65 and that PML is essential for NF-ÎºB- induced transcriptional responses. Our analysis of available transcriptional profiles of all-trans retinoic acid treated acute promyelocytic leukemia (APL) cells identifies a NF-ÎºB transcriptional programme suppressed by PML-RARÎ±. We further demonstrate that PML-RARÎ± inhibits NF-ÎºB phosphorylation and transcriptional activity. Our findings demonstrate a critical role for PML in promoting NF-ÎºB transcriptional activity which may contribute to APL initiation and maintenance. WT and PML-/- MEFs were analysed for gene expression analysis. Total of 12 samples, inlcluding triplicates were utilized. WT MEFs and PML-/- were stimulated with TNFÎ± for three hours and analysed for gene expresison using unstimulated WT MEFs as control.
