Transcription profiling of human lymphatic edothelial cells transfected with the KSHV microRNA cluster

ABSTRACT: 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 recognisable 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 KSHV virus expresses multiple microRNA in a single cluster. Here we test the effects of this KSHV microRNA cluster in LEC cells using Affymetrix hgu133plus2 chips. Experiment Overall Design: There are n=3 of: 1. LEC control with empty vector pSIN-MCS (LEC), 2. LEC transfected with the same vector containing the KSHV microRNA cluster.

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.

Transcription profiling of human LEC cells reveals KSHV manipulates notch signaling by upregulating Dll4 and JAG1 to alter cell cycle gene expression in

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. Here we examine KSHVs modulation of Notch signaling using wild-type LEC cells co-cultured with DLL4 and JAG1 expressing LEC cells. Experiment Overall Design: There are 1) n=2 of LEC control cells co-cultured with pSIN expressing LEC, 2) n=3 of LEC co-cultured with pSIN-Dll4 expressing LEC, and 3) n=3 of LEC co-cultured with pSIN-JAG1 expressing LEC.

Comparison of the transcriptome of K-LEC spheroids to control LEC spheroids

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 recognisable by its distinctive red skin lesions. The lesions are KSHV infected spindle cells expressing markers of the lymphatic endothelial and blood vessel endothelial cells as well as other cell types. The effects of KSHV infection of lymphatic endothelial cells (LEC) cultured in 3D matrix for three days were assayed using Affymetrix hgu133plus2 chips. There are n=3 of 1. control LEC spheroids (LEC), 2. KSHV infected LEC spheroids (K-LEC)

Differentially regulated splice variants and systems biology analysis of Kaposi's Sarcoma-associated Herpesvirus-infected lymphatic endothelial cells

Project description:Alternative RNA splicing greatly increases proteome diversity, and the possibility of studying genome-wide alternative splicing (AS) events becomes available with the advent of high-throughput genomics tools devoted to this issue. Kaposi’s sarcoma associated herpesvirus (KSHV) is the etiological agent of KS, a tumor of lymphatic endothelial cell (LEC) lineage, but little is known about the AS variations induced by KSHV. We analyzed KSHV-controlled AS using high-density microarrays capable of detecting all exons in the human genome. Splicing variants and altered exon-intron usage in infected LEC were found, and these correlated with protein domain modification. The different 3’ UTR used in new transcripts also help isoforms to escape microRNA-mediated surveillance. Exome-level analysis further revealed information that cannot be disclosed using classical gene-level profiling: a significant exon usage difference existed between LEC and CD34+ precursor cells, and KSHV infection resulted in LEC-to-precursor, dedifferentiation-like exon level reprogramming. Our results demonstrate the application of exon arrays in systems biology research, and suggest the regulatory effects of AS in endothelial cells are far more complex than previously observed. This extra layer of molecular diversity helps to account for various aspects of endothelial biology, KSHV life cycle and disease pathogenesis that until now have been unexplored. 5 samples were analyzed. 3 were KSHV infected lymphatic endothelial cells (LECs), and 2 were non-infected control samples.

Label free quantitative (LFQ) proteomic analysis of mouse lymphatic endothelial cells and primary mouse dendritic cells in response to IFNgamma treatment in presence or absence of 3-HKA

Project description:To explore the cellular pathways and the molecular functions affected by a novel biogenic amine, (3-HKA), we performed a label free quantitative (LFQ) proteomic analysis of mouse lymphatic endothelial cells (LEC), and primary dendritic cells, treated with IFNgammaplus or minus 3-HKA. Biological triplicates, of total cell lysates, were fractionated by one-dimensional gel electrophoresis (1DEF) and the “in gel” tryptic derived peptides analyzed by nano-LC-ESI-MS/MS on a Q Exactive HF quadrupole orbitrap mass spectrometer (Thermo Fisher Scientific, Waltham, MA, USA). LFQ analysis highlighted that 3-HKA downregulated many of the inflammatory pathways, more notably JAK/STAT1 and NFkB, associated with IFNgamma activation.
