KSHV G-protein-coupled receptor (GPCR) induced gene transcription in HUVEC cells

ABSTRACT: We used microarrays to compare the gene transcription level between HUVEC-kGPCR and HUVEC-vector stable cells. The goal is to identify the genes that are affected by KSHV kGPCR expression. We used microarrays to detail the global programme of gene expression underlying cellularisation and identified distinct classes of up-regulated genes during this process. HUVEC cells were infected with kGPCR or control lentivirus and selected with puromycin to get stable cells. Then RNA was extracted from these cells and microarray analysis was performed.

Gene array analysis of Human Umbilical Vein Endothelial Cells (HUVEC) transduced with lentivirus containing cDNA of NKX2,5 or GATA4 or GFP.

Project description:The aim of this study was to induce cardiomyogenic conversion of Human Umbilical Vein Endothelial Cells (HUVEC ) by triggering ectopic expression of the cardiac transcription factors Nkx2.5 and GATA4. Cells were cultured without cell myocardial co-culture system and transduced with lentivirus containing coding sequence of Nkx2.5, GATA4 or GFP as control. Cells were cultured in the EBM-2/ EGM-2 medium, 12 days before microarray analysis. We report in this study that over-expression of NKX2.5 and GATA4 in HUVECs stimulates the expression of some specific genes important in the cardiomyogenic differentiation process, leading to partial switch of these cells from the endothelial to the myocardial course. 12 arrays were analysed. Three competitive hybridizations to the arrays were performed in duplicate using each time, two dye-swap following this experimental design: AWA065 : CY5 (HUVEC+NKX2,5) / CY3 (HUVEC) AWA067 : CY5 (HUVEC) / CY3 (HUVEC+NKX2,5) AWA075 : CY5 (HUVEC+NKX2,5) / CY3 (HUVEC) AWA076 : CY5 (HUVEC) / CY3 (HUVEC+NKX2,5) AWA068 : CY5 ((HUVEC) / CY3 (HUVEC+GATA4) AWA070 : CY5 (HUVEC+GATA4) / CY3 ((HUVEC) AWA073 : CY5 (HUVEC+GATA4) / CY3 ((HUVEC) AWA002 : CY5 ((HUVEC) / CY3 (HUVEC+GATA4) AWA066 : CY5 (HUVEC) / CY3 (HUVEC+NKX2.5+GATA4) AWA069 : CY5 (HUVEC+NKX2.5+GATA4) / CY3 (HUVEC) AWA071 : CY5 (HUVEC+NKX2.5+GATA4) / CY3 (HUVEC) AWA074 ; CY5 (HUVEC) / CY3 (HUVEC+NKX2.5+GATA4)

Comparison of gene expression between Human umbilical vein endothelial cells and Human liver sinusoidal endothelial cells

Project description:To identify leukocyte adhesion receptors which differentially regulate recruitment in human liver sinusoidal endothelial cells compared to a protoptypic venular endothelium Gene expression was measured in four groups Group 1: cultured human liver sinusoidal endothelial cells (HSEC) Group 2: cultured human umbilical vein endothelial cells (HUVEC) Group3: Interferon gamma and tumour necrosisfactor alpha treated HSEC and Group 4: Interferon gamma and tumour necrosisfactor alpha treated HUVEC. Two replicates were used for each group.

The profile of cellular and KSHV microRNAs in KSHV infected lymphatic endothelial cells (6 and 72 hours post infection)

Project description:Kaposi sarcoma is the most common cancer in AIDS patients and is typified by red skin lesions. The disease is caused by the KSHV virus (HHV8) and is recognizable by its distinctive red skin lesions. The lesions are KSHV infected spindle cells, most commonly the lymphatic endothelial and blood vessel endothelial cells (LEC and BEC), plus surrounding stroma. The effects of KSHV infection of LECs were assayed using Affymetrix hgu133plus2 chips at 6 and 72 hours post infection. There were n=4 each of lymphatic endothelial cells (LEC) following 6 hours of culture, LEC following 6 hours post KSHV infection, LEC following 72 hours of culture, and LEC following 72 hours post KSHV infection.

HUVECs with endogenous or overexpressed GPR4 treated with pH 8.4 (control) or pH 6.4 for 5 h

Project description:Acidic tissue microenvironment is commonly found in a variety of pathophysiological conditions. GPR4 is a proton-sensing G protein-coupled receptor that is fully activated by acidic extracellular pH but has lesser activity at the physiological pH 7.4 and minimal activity at more alkaline pH. To determine the effects of GPR4 activation by acidosis on vascular endothelial cells, we examined the global gene expression of the acidosis response in primary human umbilical vein endothelial cells (HUVEC) with varying level of GPR4. HUVEC with endogenous or overexpressed GPR4 level (designated as HUVEC/Vector & HUVEC/GPR4 cells). Two treatment conditions: pH 6.4 vs. pH 8.4 for 5 h. Biological replicates: 4 HUVEC/Vector replicates (pH6.4 vs pH 8.4), and 4 HUVEC/GPR4 replicates (pH6.4 vs pH 8.4).

Low- and middle-dose of radiation on hNPC and HUVEC

Project description:Many neural progenitor cells present in the fetus, but also in adult brain, which play a major role for the reproduction for healingin regeneration of neuronal cells, when differentiated cells are damaged. However, effects of radiation effect on undifferentiated neural progenitor cells remained unclear. The radiation doses of medical exposure, pollution by nuclear power plant accidents, and other exposure of workers; medical workers, airline crews, and astronaut have been focused. In this study, we report the effects of low- to middle- dose doses of radiation on cultured human neural progenitor cells (hNPC) differentiated derived from embryonic stem (ES) cells, which are partially compared with those of human umbilical vein endothelial cell (HUVEC). Gene expression was changed by continuous exposure of 31mGy; 0.0072 mGy/ minute, 124mGy; 0.029 mGy/ minute and 496mGy; 0.085 mGy/ minute for seventy-two hours. While shortening in neurite length by 124mGy was not significant, its decrease was observed by 496 mGy of radiation. Number of altered pathways increased dose-dependently. By thirty-one mGy per 72 hours of radiation, gene expression of inflammatory pathways involving interferon and cell junction were changed. By 124 mGy of radiation, DNA double strand break repair pathways and cell adhesion molecules were affected. Then, 496 mGy of radiation for 72 hours altered translational DNA synthesis pathway, apoptotic pathway, various metabolic pathways and neural differentiation pathways. Dose-dependent transcriptional changes by low- to middle- radiation are consistent with gradual axonal shortening, growth arrest and neural cell death. Undifferentiated hNPC derived from embryonic stem (ES) cells and HUVECs synchronized in G1 cell cycle phase were irradiated from sealed cesium-137 for 72 h.
