Patent ID: 10227591

Abstract:
The present invention relates to miR145, miR132, miR212, and the genes or gene products regulated by these miRNAs. miR145 is downregulated in cells infected with HCMV. This downregulation modulates expression of miR145 target genes, including IRS-1. Transfection of cells with a miR145 agent, such as a miR145 mimetic, reduces HCMV replication and protein expression. miR132 and miR212 are upregulated in cells infected with HCMV. This upregulation modulates expression of miR132 and miR212 target genes, including MeCP2 and RICS. Transfection of cells with a miR132 and/or a miR212 antagonist reduces HCMV replication and protein expression. Accordingly, the invention provides methods of attenuating HCMV replication by modulating, for example, miR145, miR132, and/or miR212, and targets thereof. Also provided are methods of detecting an HCMV infection, and compositions and kits useful for attenuating HCMV replication.
