Kaposi’s Sarcoma-Associated Herpesvirus microRNAs
Kaposi's sarcoma-associated herpesvirus (KSHV) is a human pathogenic γ-herpesvirus strongly associated with the development of Kaposi's Sarcoma and B cell proliferative disorders, including primary effusion lymphoma (PEL). The identification and functional investigation of non-coding RNAs expressed by KSHV is a topic with rapidly emerging importance. KSHV miRNAs derived from 12 stem-loops locat...
متن کاملRegulation of herpesvirus reactivation by host microRNAs.
The interplay between latent and lytic modes of infection is central to successful infection of all herpesviruses, yet knowledge of the determinants that govern reactivation of these viruses from latent to lytic infection is limited. Recently, several studies have identified roles for specific cellular microRNAs in inhibiting reactivation of various herpesviruses, thereby promoting latent infec...
متن کاملMicroRNAs: biogenesis and molecular functions.
Small regulatory RNAs are essential and ubiquitous riboregulators that are the key mediators of RNA interference (RNAi). They include microRNAs (miRNAs) and short-interfering RNAs (siRNAs), classes of approximately 22 nucleotide RNAs. miRNAs and siRNAs bind to Argonaute proteins and form effector complexes that regulate gene expression; in animals, this regulation occurs primarily at the post-t...
متن کاملMicroRNAs: Mechanisms, Functions and Progress
In 1993 when Ambros and co-workers [1] discovered that a mysterious Caenorhabditis elegans gene, lin-4, does not encode a protein, but acts in the form of a small RNA and represses the expression of its target gene, lin-14, through base-pairing with its 30 untranslated region (30UTR), nobody would imagine that 20 years later, this category of small RNAs – now widely known as microRNAs (or miRNA...
متن کاملKaposi's Sarcoma Herpesvirus microRNAs Target Caspase 3 and Regulate Apoptosis
Kaposi's sarcoma herpesvirus (KSHV) encodes a cluster of twelve micro (mi)RNAs, which are abundantly expressed during both latent and lytic infection. Previous studies reported that KSHV is able to inhibit apoptosis during latent infection; we thus tested the involvement of viral miRNAs in this process. We found that both HEK293 epithelial cells and DG75 cells stably expressing KSHV miRNAs were...
