Chemists at UCL and the MRC Laboratory of Molecular Biology have demonstrated how RNA (ribonucleic acid) might have ...

The expression of symptoms of viral infections is a byproduct of complex virus-host molecular pathways. These remain largely ...

The molecular pathways involved in antiviral defenses and counter-defenses in host-pathogen systems remain unclear. Researchers have used Neurospora crassa as a model organism to explore how RNA ...

Using either short double stranded RNA (dsRNA) or large RNA molecules, two groups independently show that RNA can have a role in the up- or downregulation of gene expression at the transcriptional ...
