Bombyx mori cytoplasmic polyhedrosis virus (BmCPV) is one of the major pathogens that pose a big challenge to the sericulture industry. Growing evidences have shown that microRNAs play key roles in the regulations of host-pathogen interactions in insects. MicroRNAs have been found in silkworms, whether and how they affect the silkworm-BmCPV interactions are still unknown. Here we investigate the effect of miR-274-3p on the BmCPV replication in the BmCPV-infected silkworm larvae. In our study, BmCPV Nonstructural protein 5 (NS5) was identified to be the target of miR-274-3p based on bioinformatics analysis and luciferase reporter assay. The abundance of NS5 was significantly increased in the presence of miR-274-3p inhibitor based on the qRT-PCR and Western blotting results. Further, qRT-PCR results revealed that the expression of polyhedrin gene of BmCPV in the larvae after applying miR-274-3p inhibitor was significantly increased comparing with that of larvae with negative control. Our results suggest that inhibition of miR-274-3p could facilitate BmCPV replication by up-regulating BmCPV NS5 gene expression and are insightful for further exploring the interactions between silkworm and BmCPV.
