Abstract MicroRNAs are a recently discovered class of small noncoding functional RNAs. These molecules mediate post-transcriptional regulation of gene expression in a sequence specific manner. MicroRNAs are now known to be key players in a variety of biological processes and have been shown to be deregulated in a number of cancers. The discovery of viral encoded microRNAs especially from a family of oncogenic viruses has attracted immense attention towards the possibility of microRNAs as critical modulators of viral oncogenesis. The host-virus crosstalk mediated by microRNAs messenger RNAs and proteins is complex and involves the different cellular regulatory layers. In this commentary we describe models of microRNA mediated viral oncogenesis. Background Interest in the involvement of infectious agents in oncogenic transformation and more so viruses has been of historical importance probably starting with Rous discovery of filterable particles that could transmit avian sarcoma 1 . This was followed by the discovery .
