(Submitter supplied) In mammalian somatic cells, the relative contribution of RNAi and the type I interferon response during viral infection is unclear. The apparent inefficiency of antiviral RNAi might be due to self-limiting properties and mitigating co-factors of the key enzyme Dicer. In particular, the helicase domain of human Dicer appears to be an important restriction factor of its activity. Here, we study the involvement of several helicase-truncated mutants of human Dicer in the antiviral response. more...

(Submitter supplied) Purpose: Next-generation sequencing (NGS) on targeted locus in Sindbis genome to determine frequency changes of artificial microRNAs expressed by viruses after passaging in cancer and normal cells Methods: RNA was harvested in Trizol 488 (Thermo Fisher). RNA was extracted using the manufacturer’s protocol and quantified by nanodrop. Sequencing was done by SeqMatic on a MiSeq v3 platform generating 75bp reads. more...

(Submitter supplied) Sindbis virus is a mutagenic ssRNA arbor virus. The structural genome component of this virus can be exchanged for any transgene of < 6kb in size. Here we sequence transgenic elements inserted to the virus. Our EGFP transgene was analyzed as a function of time during viral replication to quantify the mutagenic rate of the virus. Our nanobody transgene was analyzed to assess cDNA library complexity and identity.

(Submitter supplied) Alphaviruses are arthropod-borne viruses that represent a significant threat to public health at a global level. While the formation of alphaviral nucleocapsid cores, consisting of cargo nucleic acid and the viral capsid protein, is an essential molecular process of infection, the precise interactions between the two partners are ill-defined. A CLIP-seq approach was used to screen for candidate sites of interaction between the viral Capsid protein and genomic RNA of Sindbis virus (SINV), a model alphavirus. more...

(Submitter supplied) The role of RNA silencing as a defense mechanism against viruses remains to be formerly established in mammalian somatic cells. Here, we determined the antiviral properties of human and Drosophila Dicer proteins in a heterologous setup. We expressed human Dicer (hDicer) in Drosophila, and Drosophila Dicer-2 in human cells, and measured the impact on the response to Sindbis virus (SINV) infection. In flies, hDicer presents a low processing activity, but partially rescues a Dcr2 null mutation in flies. more...
