Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Infection of Kaposi's sarcoma associated herpes virus (KSHV) has been linked to the development of primary effusion lymphoma (PEL), which is characterized by the loss of expression of B cell markers and effusions in the body cavities. This unique clinical feature of PEL has been attributed to their distinctive gene expression profile which shows overexpression of genes in various signaling pathways. KSHV-encoded latent protein vFLIP K13 has been shown to promote the survival and proliferation of PEL cells. In this study, we have employed gene array analysis followed by bioinformatics analysis of coordinated transcriptional factors network as well as biological pathways to characterize the effect of K13 on PEL-derived BCBL1 cells. We observed that genes associated with Cytokine signaling, Cell death, NF-kappaB and Cell adhesion pathways were differentially regulated by K13.

Description
Integrated microarray and multiplex cytokine analyses of Kaposi's Sarcoma Asssociated Herpesvirus viral FLICE Inhibitory Protein K13 affected genes and cytokines in human blood vascular endothelial cells. The KSHV-encoded K13 protein is one of the few proteins to be expressed in latently-infected spindle cells and the ectopic expression of K13 in human vascular endothelial cells is sufficient to transform them into spindle cells.

- Affymetrix Human Genome U133A 2.0 Array (hgu133a2)
Description
We report here that KSHV viral infection targets the NF-kB pathway which is crucial for cell survival. KSHV protein vFLIP K13 is known to directly interact with cellular protein NEMO of the NF-kB pathway. We used gene expression array to suggets that the interaction of K13 with NEMO is important to activate NF-kB pathway.
Publication Title
NEMO is essential for Kaposi's sarcoma-associated herpesvirus-encoded vFLIP K13-induced gene expression and protection against death receptor-induced cell death, and its N-terminal 251 residues are sufficient for this process.

Description
Circular RNAs (circRNAs) are a class of noncoding RNAs produced by a non-canonical form of alternative splicing called back-splicing. To investigate a potential role of circRNAs in the p53 pathway, we analyzed RNA-seq data from colorectal cancer cell lines (HCT116, RKO and SW48) in the presence or absence of DNA damage. Surprisingly, unlike the strong p53-dependent induction of hundreds of p53-induced mRNAs, only a few circRNAs were induced from the p53-induced genes. Circ-MDM2, an annotated circRNA from the MDM2 locus, was one of the handful of circRNAs that originated from a p53-induced gene. Given the central role of MDM2 in suppressing p53 protein levels and p53 activity, we investigated the function of circ-MDM2. Knocking down circ-MDM2 with siRNAs that targeted the circ-MDM2 junction and had no effect on linear MDM2 mRNA, resulted in increased basal p53 levels and growth defects in vitro and in vivo. Consistent with these results, transcriptome profiling showed increased expression of several direct p53 targets, reduced Rb phosphorylation and defects in G1-S progression upon silencing circ-MDM2. Our results reveal the role of a novel circRNA by which the MDM2 locus suppresses p53 levels and cell cycle progression.
