Abstract:
MicroRNAs (miRNAs) are an integral part of gene regulation
at the post-transcriptional level. Recently, it has been shown
that pairs of miRNAs can repress the translation of a target
mRNA in a cooperative manner, which leads to an enhanced
effectiveness and specificity in target repression. However, it
remains unclear which miRNA pairs can synergize and which genes
are target of cooperative miRNA regulation. In this paper, we
present a computational workflow for the prediction and
analysis of cooperating miRNAs and their mutual target genes,
which we refer to as RNA triplexes. The workflow integrates
methods of miRNA target prediction; triplex structure analysis;
molecular dynamics simulations and mathematical modeling for a
reliable prediction of functional RNA triplexes and target
repression efficiency. In a case study we analyzed the human
genome and identified several thousand targets of cooperative
gene regulation. Our results suggest that miRNA cooperativity
is a frequent mechanism for an enhanced target repression by
pairs of miRNAs facilitating distinctive and fine-tuned target
gene expression patterns. Human RNA triplexes predicted and
characterized in this study are organized in a web resource at
www.sbi.uni-rostock.de/triplexrna/.

Project description:In the current study, we examined the cellular and viral miRNA expression profile in KSHV-infected patients without clinical signs of KSHV-associated disease. In addition, we characterized the viral miRNAs encoded by KSHV and EBV during natural infections in these patients. Finally, we show that malaria infection results in major alterations of the molecular content of plasma exosomes.

Project description:This SuperSeries is composed of the SubSeries listed below. Purpose: Kaposi’s sarcoma (KS)-associated herpesvirus (KSHV) causes several lymphoproliferative disorders, including KS, a common AIDS-associated malignancy. Cellular and viral microRNAs (miRNAs) have been shown to play important roles in regulating the expression of genes in oncogenesis. Herpesviruses, including KSHV, encode for miRNAs that are involved in angiogenesis, inflammation and apoptosis. A better knowledge of the miRNA-mediated pathways that regulate KSHV infection is therefore essential for an improved understanding of viral infection and pathogenesis. Methods: In this study, we used deep sequencing to analyze miRNA, both viral and human, and mRNA expression in KS tumor-derived human cells. Results: This approach revealed 153 differentially expressed human miRNAs between KSHV-positive and -negative cells. Differential expression of eight miRNAs was independently confirmed by qRT-PCR. We additionally showed that a majority (~73%) of KSHV-regulated miRNAs are down-regulated, including most members of the 14q32 miRNA cluster. Specifically, human miR-409-3p, which is known to target the pro-angiogenic growth factor angiogenin and the inflammation marker fibrinogen-beta, was significantly down-regulated in KSHV-infected cells based on deep sequencing and qRT-PCR. Despite this substantial down-regulation of cellular miRNAs, hsa-miR-708-5p was significantly up-regulated by KSHV and has been shown to directly inhibit pro-apoptotic protease Caspase-2. Finally, we evaluated to what extent there was an inverse correlation between miRNA and mRNA expression levels. Using filtered datasets, we identified relevant canonical pathways that were significantly enriched. Conclusion: Taken together, our data demonstrate that most human miRNAs affected by KSHV are repressed and our findings highlight the relevance of studying the post-transcriptional gene regulation of miRNAs for KSHV-associated malignancies.

Project description:Purpose: Kaposi’s sarcoma associated-herpesvirus (KSHV) causes several hyperproliferative disorders, including Kaposi’s sarcoma, primary effusion lymphoma and multicentric Castleman’s disease. KSHV encodes for a number of microRNAs (miRNAs), and KSHV infection can affect the expression of cellular miRNAs. Hypoxia has been shown to induce KSHV reactivation, directly induce several KSHV lytic genes, and also induce the most abundant latent viral protein, LANA. Also, several KSHV proteins can stabilize and increase the cellular levels of hypoxia-inducible factor (HIF-1α). However, the degree to which hypoxic pathways are utilized by KSHV has yet to be determined. Methods: We investigated the interplay between hypoxia and KSHV infection by comparing the 31effects of hypoxia and KSHV infection on miRNA and mRNA expression, and by examining the 32effects of hypoxia on uninfected and KSHV-infected cells. This was accomplished using next-33generation sequencing (NGS), qRT-PCR, Taqman assays, and pathway analysis. Results: NGS analysis of human mRNAs revealed striking similarities (~34%) between the transcriptomic response to hypoxia and the transcriptomic response to KSHV infection. Additionally, hsa-miR-210, a key hypoxia-inducible miRNA with pro-angiogenic and anti-apoptotic properties, was found significantly up-regulated by both KSHV infection and hypoxia using Taqman assays. Finally, KSHV infected cells differed somewhat in their response to hypoxia compared to KSHV-uninfected controls. Conclusions: These results demonstrate that KSHV harnesses a part of the hypoxic cellular response and induces miR-210 up-regulation. The understanding of how these miRNAs, genes and pathways are regulated by HIF-1α and KSHV infection are essential to a better understanding of the biology of KSHV-associated diseases.
