Abstract :

The discovery of microRNAs (miRs) encoded by viruses indicates that these small noncoding RNAs play a role in their life cycle and associated diseases. Kaposi�s sarcomaassociated herpesvirus (KSHV), an oncogenic virus associated with Kaposi�s sarcoma (KS) and several other lymphoproliferative diseases, encodes 25 miRs derived from 12 pre-miRs. Recent works from our laboratory and others have shown that KSHV miRs promote viral latency, which is a strategy to evade host immune surveillance, by either directly targeting essential viral replication genes or upregulating specifi c cellular pathways such as NF-kB pathway to inhibit viral replication. Genetic dissection reveals that KSHV miRs are also required for KSHV-induced cellular transformation and tumor induction. Further genetic complementation has identifi ed the specifi c miRs and the targeted cellular pathways that mediate KSHV cellular transformation and tumor formation. A systems biology approach was used to identify a number of specifi c targets, providing insight into the molecular mechanism mediates cellular transformation of these viral miRs, and implicating their potential use as therapeutic targets.
