KSHV vIRF3 promotes angiogenesis of lymphatic endothelial cells (LECs)

ABSTRACT: Herein, we report viral interferon regulatory factor 3 (vIRF3) as a pro-angiogenic factor together with HDAC5 that coordinates with LEC transcriptome, thus resulting in hyper-sprouting formation and ultimately leading to abnormal lymphangiogenesis. Overexpression of vIRF3 in LECs but not blood endothelial cells (BECs) exhibited a unique KSHV-associated angiogenic effect, evidenced by elongated spindle shape, sprouting, and tube formation. Furthermore, using vIRF3 knockout recombinant KSHV, we confirmed that vIRF3 is a critical factor of KSHV-mediated lymphangiogenesis in primary LECs.

LETR1 (LINC01197) RNA pull-down in human LECs followed by LC-MSMS

Project description:Recent studies have revealed the importance of long noncoding RNAs (lncRNAs) as tissue-specific regulators of gene expression. There is ample evidence that distinct types of vasculature undergo tight transcriptional control to preserve their structure, identity, and functions. We determined, for the first time, the global lineage-specific lncRNAome of human dermal blood and lymphatic endothelial cells (BECs and LECs), combining RNA-Seq and CAGE-Seq. A subsequent genome-wide antisense oligonucleotide-knockdown profiling of two BEC- and two LEC-specific lncRNAs identified LETR1 as a critical gatekeeper of the global LEC transcriptome. Deep RNA-DNA and RNA-protein interaction studies, and phenotype rescue analyses revealed that LETR1 is a nuclear trans-acting lncRNA modulating, via key epigenetic factors, the expression of essential target genes governing the growth and migratory ability of LECs. Together, our study provides new evidence supporting the intriguing concept that every cell type expresses precise lncRNA signatures to control lineage-specific regulatory programs.

RNAi of human HUVEC cells knocked down for HDAC isoenzymes reveals sHDAC5 is a repressor of angiogenesis and determines the angiogenic gene expression pattern of endothelial cells

Project description:Class IIa histone deacetylases (HDACs) are signal-responsive regulators of gene expression involved in vascular homeostasis. To investigate the differential role of class IIa HDACs for the regulation of angiogenesis, we used siRNA to specifically suppress the individual HDAC isoenzymes. Among the HDAC isoforms tested, silencing of HDAC5 exhibited a unique pro-angiogenic effect evidenced by increased endothelial cell migration, sprouting and tube formation. Consistently, overexpression of HDAC5 decreased sprout formation, indicating that HDAC5 is a negative regulator of angiogenesis. The anti-angiogenic activity of HDAC5 was independent of MEF2 binding and its deacetylase activity, but required a nuclear localization indicating that HDAC5 might affect the transcriptional regulation of gene expression. To identify putative HDAC5 targets, we performed microarray expression analysis. Silencing of HDAC5 increased the expression of fibroblast growth factor 2 (FGF2) and angiogenic guidance factors including Slit2. Antagonization of FGF2 or Slit2 reduced sprout induction in response to HDAC5 siRNA. ChIP assays demonstrate that HDAC5 binds to the promoter of FGF2 and Slit2. In summary, HDAC5 represses angiogenic genes, like FGF2 and Slit2, which causally contribute to capillary-like sprouting of endothelial cells. The de-repression of angiogenic genes by HDAC5 inactivation may provide a useful therapeutic target for induction of angiogenesis. Experiment Overall Design: 6 samples: 3x siSCRAMBLED transfected HUVEC (control) + 3x siHDAC5 transfected HUVEC 24h after transfection

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.

Expression data from two sorted lymphatic endothelial cell (LEC) populations, podoplanin-high versus podoplanin low

Project description:Extracorporeal shockwave treatment was shown to improve orthopaedic diseases, wound healing and to stimulate lymphangiogenesis in vivo. The aim of this study was to investigate in vitro shockwave treatment (IVSWT) effects on lymphatic endothelial cell (LEC) behavior and lymphangiogenesis. We analyzed migration, proliferation, vascular tube forming capability and marker expression changes of LECs after IVSWT compared with HUVECs. Finally, transcriptome- and miRNA analyses were conducted to gain deeper insight into the IVSWT-induced molecular mechanisms in LECs. The results indicate that IVSWT-mediated proliferation changes of LECs are highly energy flux density-dependent and LEC 2D as well as 3D migration was enhanced through IVSWT. IVSWT suppressed HUVEC 3D migration but enhanced vasculogenesis. Furthermore, we identified podoplaninhigh and podoplaninlow cell subpopulations, whose ratios changed upon IVSWT treatment. Transcriptome- and miRNA analyses on these populations showed differences in genes specific for signaling and vascular tissue. Our findings help to understand the cellular and molecular mechanisms underlying shockwave-induced lymphangiogenesis in vivo. Immortalized lymphatic endothelial cells were flow-sorted in two populations according to their differences in FSC and SSC values and subjected to Affymetrix analysis in triplicate samples

Comparative transcriptional profiling of tumor-associated and normal lymphatic endothelial cells

Project description:In the past decade, the relevance of tumor-induced lymphangiogenesis for the metastatic spread of tumor cells has been demonstrated, thus indicating the potential of targeting tumor lymphangiogenesis to treat cancer. Whereas numerous preclinical studies demonstrated that blocking angiogenesis or lymphangiogenesis could inhibit tumor metastasis, the scarcity of highly selective targeting candidates hampers their translation to the clinic. We employed a new approach consisting of immuno-laser capture microdissection (i-LCM) and transcriptional profiling by means of microarrays in order to identify novel tumor-specific endothelial markers. By using short immunostainings prior to microdissection, specific identification of lymphatic (LECs) and blood (BECs) endothelial cells was allowed. For the subsequent gene expression profiling, a single round of the Ribo-Spia amplification method in combination with the Affymterix microarray platform was used. Comparison of gene expression profiles of tumor-associated and normal LECs resulted in the identification of differentially expressed genes in tumor-associated lymphatic vasculature.
