(Submitter supplied) lncRNAs regulate protein functions via formation of protein-RNA complexes. Previous studies have shown that expression of viral lncRNA, polyadenylated nuclear RNA (PAN RNA) is essential for inducible viral genomic looping and distal gene activation during Kaposi's sarcoma-associated herpesvirus (KSHV) reactivation. Here we show an underlying molecular mechanism and regulation of KSHV latency by a viral lncRNA-CHD4 (chromodomain helicase DNA binding protein 4) interaction. more...

(Submitter supplied) The Kaposi's sarcoma-associated herpesvirus (KSHV) genome consists of an approximately 140 kb unique coding region flanked by 30-40 copies of 0.8 kb terminal repeat (TR) sequence. KSHV genomes persist in latently infected cells as episomes via tethering to the host cell chromosomes, and KSHV latency associated nuclear antigen (LANA) plays a crucial role in latent episomal DNA replication and segregation during host cell mitosis by binding to TR. more...

(Submitter supplied) Latency-associated nuclear antigen (LANA), a multifunctional protein expressed by the Kaposi sarcoma-associated herpesvirus (KSHV) in latently-infected cells, is required for stable maintenance of the viral episome. This is mediated by two interactions: LANA binds to specific sequences (LBS1 and 2) on viral DNA, and also engages host histones, tethering the viral genome to host chromosomes in mitosis. more...

(Submitter supplied) Human SLK cells were infected with wildtype (wt) and LANA knockout (KO) Kaposi's sarcoma-associated herpesvirus (KSHV), separately for 3 days. Cellular gene expression changes were identified upon the wild type and LANA KO KSHV virus infection compared to the uninfected SLK cells using the human gene expression microarray U133plus2.0.

(Submitter supplied) Kaposi’s sarcoma-associated herpesvirus (KSHV) is a g-herpesvirus which persists as circular extrachromasomal DNA in the nucleus during latent infection. During latency a limited number of viral proteins are expressed, including LANA (latency-associated nuclear antigen). LANA is a multi-functional protein known to interact with transcriptional regulators and chromatin remodelers, and to regulate the LANA and RTA promoters. more...

(Submitter supplied) Higher order genome structure influences the transcriptional regulation of cellular genes through the juxtaposition of regulatory elements, such as enhancers, close to promoters of target genes. While enhancer activation has emerged as an important facet of Kaposi’s sarcoma-associated herpesvirus (KSHV) biology, mechanisms controlling enhancer-target gene expression remain obscure. Here, we discover that the KSHV genome tethering protein latency-associated nuclear antigen (LANA) potentiates enhancer-target gene expression in primary effusion lymphoma (PEL), a highly aggressive B cell lymphoma causally associated with KSHV. more...

(Submitter supplied) Kaposi's sarcoma-associated herpesvirus (KSHV) is a human oncogenic virus, which maintains the persistent infection of the host by intermittently reactivating from latently infected cells to produce viral progenies. Here, we performed a comprehensive time course transcriptome analysis during KSHV reactivation in KSHV+ primary effusion B-cell lymphoma cells (PEL). For this we used a recombinant PEL cell line called TRExBCBL1-3xFLAG-RTA. more...

(Submitter supplied) Chromatin immunoprecipitation coupled with high-throughput sequencing (ChIP-seq) analysis was performed during Kaposi's sarcoma-associated herpesvirus (KSHV) reactivation in KSHV+ recombinant primary effusion B-cell lymphoma cells (PEL). RTA binding sites were identified genome-wide in a recombinant PEL cell line called TRExBCBL1-3xFLAG-RTA cells at 12 hours post-induction (hpi) of RTA expression.

(Submitter supplied) CTCF and the cohesin complex modify chromatin by binding to DNA and interacting with each other and with other cellular proteins. Both proteins regulate transcription by a variety of local effects on transcription and by long range topological effects. CTCF and cohesin also bind to herpesvirus genomes at specific sites and regulate viral transcription during latent and lytic cycles of replication. more...

(Submitter supplied) LANA is essential for tethering the KSHV genome to metaphase chromosomes and for modulating host-cell gene expression, but the binding sites in the host-chromosome remain unknown. Here, we use LANA-specific chromatin immunoprecipitation coupled with high-throughput sequencing (ChIP-Seq) to identify LANA binding sites in the viral and host-cell genomes of a latently infected pleural effusion lymphoma cell line BCBL1. more...
