This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Open reading frame 11 (ORF11) of Kaposi's sarcoma-associated herpesvirus belongs to a herpesviral homologous protein family shared by some members of the gamma- herpesvirus subfamily. Little is known about this ORF11 homologous protein family. We have characterized an unknown open reading frame, ORF11, located adjacent and in the opposite orientation to a well-characterized viral IL-6 gene. Northern blot analysis reveals that ORF11 is expressed during the KSHV lytic cycle with delayed-early transcription kinetics. We have determined the 5(prime) and 3(prime) untranslated region of the unspliced ORF11 transcript and identified both the transcription start site and the transcription termination site. Core promoter region, representing ORF11 promoter activity, was mapped to a 159nt fragment 5(prime) most proximal to the transcription start site. A functional TATA box was identified in the core promoter region. Interestingly, we found that ORF11 transcriptional activation is not responsive to Rta, the KSHV lytic switch protein. We also discovered that part of the ORF11 promoter region, the 209nt fragment upstream of the transcription start site, was repressed by phorbol esters. Our data help to understand transcription regulation of ORF11 and to elucidate roles of ORF11 in KSHV pathogenesis and life cycle.
Download or read book Kaposi s Sarcoma associated Herpesvirus Replication and Transcription Activator Regulates Extracellular Matrix Signal Pathway written by Daniel Pfalmer and published by . This book was released on 2016 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Kaposi’s Sarcoma (KS) is a malignancy caused by infection with Kaposi’s Sarcoma-associated Herpesvirus [KSHV; also known as Human Herpesvirus 8 (HHV8)] in which tumor cells show a characteristic ‘spindle-like’ morphology. The transcription factor RTA (Replication and Transcription Activator) is the viral protein responsible for reactivating KSHV from its latent state. Production of RTA in latently infected cells causes a number of viral proteins to be produced and leads to a cascade of gene expression changes in both viral and host genes. Previous work in our lab showed that RTA was capable of reprogramming cells in vitro to display a spindle-like morphology. In this study we aimed to identify the host gene expression changes caused directly by RTA which could be responsible for that reprogramming. To that end, Madin-Darby Canine Kidney cells (MDCK cells) were chosen as a model for KSHV-naïve mammalian cells. Differences in host gene expression levels in a culture of MDCK cells transfected with a plasmid coding for expression of RTA compared to MDCK cells transfected with a similar plasmid lacking the RTA gene were measured by whole transcriptome sequencing (RNA-Seq). Cells containing the RTA-coding plasmid adopted a spindle-like morphology and showed at least a two-fold change in expression level in approximately 180 genes. Those 180 genes were then screened for known associations to signaling pathways in order to determine which might be involved with the morphological changes observed and/or biological significance. The expression levels of the 10 genes identified by that screening were then verified by quantitative real time PCR (qPCR). Of those 10 genes, eight were identified as potentially associated with the morphological changes, including three genes associated with extra cellular matrix (ECM) destruction (MMP9, CTSD, and CTSS) that were down-regulated; two genes associated with blocking ECM destruction (TIMP1 and TIMP2) that were pregulated; two ECM component genes (LAMC2 and COL1A2) that were upregulated; and one gene associated with blocking cell-cell and cell-ECM adhesion (MUC1) that was downregulated. The remaining two genes (MAP2K1 and podoplanin) were identified as potentially biologically significant, but not directly involved in regulating morphology. MAP2K1 is associated with epithelial dedifferentiation and was down-regulated; and the lymphatic endothelial specific marker podoplanin (PDPN) was up-regulated. Taken together, the differences in morphology and gene expression between RTA-producing cells and controls suggest a possible role for RTA in the formation of the spindle cells that characterize Kaposi’s sarcoma.

Download or read book Heparanase written by Israel Vlodavsky and published by Springer Nature. This book was released on 2020-04-09 with total page 871 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by internationally recognized leaders in Heparanase biology, the book’s eight chapters offer an opportunity for scientists, clinicians and advanced students in cell biology, tumor biology and oncology to obtain a comprehensive understanding of Heparanase’s multifaceted activities in cancer, inflammation, diabetes and other diseases, as well as its related clinical applications. Proteases and their involvement in cancer progression have been well addressed and documented; however, the emerging premise presented within this book is that Heparanase is a master regulator of aggressive cancer phenotypes and crosstalk with the tumor microenvironment. This endoglycosidase contributes to tumor-mediated remodeling of the extracellular matrix and cell surfaces, augmenting the bioavailability of pro-tumorigenic and pro-inflammatory growth factors and cytokines that are bound to Heparan sulfate. Compelling evidence ties Heparanase with all steps of tumor progression including tumor initiation, growth, angiogenesis, metastasis, and chemoresistance, supporting the notion that Heparanase is an important contributor to the poor outcome of cancer patients and a validated target for therapy. Unlike Heparanase, heparanase-2, a close homolog of Heparanase, lacks enzymatic activity, inhibits Heparanase, and regulates selected genes that promote normal differentiation and tumor suppression. Written by internationally recognized leaders in Heparanase biology, this volume presents a comprehensive understanding of Heparanase’s multifaceted activities in cancer, inflammation, diabetes and other diseases, as well as its related clinical applications to scientists, clinicians and advanced students in cell biology, tumor biology and oncology.
