Transcriptional regulation of the Kaposi's sarcoma-associated herpesvirus K15 gene.
The K15 gene product of Kaposi's sarcoma-associated herpesvirus (KSHV) is a transmembrane protein that is encoded by the last open reading frame of the KSHV genome. The K15 protein has been implicated in modulation of B-cell signal transduction and activation of the Ras/mitogen-activated protein kinase and NF-kappaB signal transduction pathways. Here we report the identification of the transcri...
متن کاملTranscriptional regulation of the interleukin-6 gene of human herpesvirus 8 (Kaposi's sarcoma-associated herpesvirus).
Human herpesvirus 8 (HHV-8; Kaposi's sarcoma-associated herpesvirus is linked to Kaposi's sarcoma (KS), primary effusion lymphoma (PEL), and multicentric Castleman's disease (MCD), all of which are viewed as cytokine-driven malignancies. In particular, interleukin-6 (IL-6) has been found to promote the growth and proliferation of cells from KS and PEL. HHV-8 encodes a homologue of IL-6 (viral I...
متن کاملTranscriptional regulation of the K1 gene product of Kaposi's sarcoma-associated herpesvirus.
The K1 protein of Kaposi's sarcoma-associated herpesvirus (KSHV) has been shown to be a transforming protein capable of inducing morphological changes and focus formation in rodent fibroblasts. K1 can activate B-cell receptor (BCR) signaling and upregulate activity of the NFAT and NF-kappaB transcription factors. In order to understand the regulation of K1 gene expression, we have analyzed sequ...
متن کاملTranscriptional origin of Kaposi's sarcoma-associated herpesvirus microRNAs.
Kaposi's sarcoma-associated herpesvirus (KSHV) encodes 11 distinct microRNAs, all of which are found clustered within the major latency-associated region of the KSHV genome in the same transcriptional orientation. Because the KSHV microRNAs are all expressed in latently infected cells and are largely unaffected by induction of lytic replication, it appeared probable that they would be processed...
متن کاملTranscriptional control of herpesvirus gene expression: gene functions required for positive and negative regulation.
We have used an in vitro nuclear run-off assay to measure the levels of transcription of specific herpes simplex virus genes at different times during a lytic infection. We analyzed the effects of inhibition of DNA replication and of defects in two herpes simplex virus regulatory proteins on the transcription of these genes. We present evidence that the transcription of the alpha ICP4 gene is n...
