Abstract:
:Bombyx mori nucleopolyhedrovirus (BmNPV) is one of the main pathogens that seriously affect the sustainable development of sericulture industry. Inhibition of Hsp90 by Hsp90 inhibitor, geldanamycin (GA) significantly suppresses BmNPV proliferation in Bombyx mori, while the functional mechanism is not clear. LncRNA has been widely reported to play an important role in immune responses and host-virus interactions in mammalian. However, related research has been rarely reported on silkworm. In this study, firstly, we confirmed the decrease of BmNPV ORF75 protein in the BmNPV-infected BmN cells treated with GA. Next, by using a genome-wide transcriptome analysis, we compared the lncRNA and mRNA expression profiles in BmNPV infected BmN cells treated with or without GA and identified a total of 282 differentially expressed lncRNAs (DElncRNAs) and 523 DEmRNAs. KEGG pathway analysis revealed DEmRNA were mainly involved in ubiquitin mediated proteolysis, spliceosome, RNA transport and oxidative phosphorylation. Further, we selected 27 immune-related DEmRNAs, which displayed the similar changes of expression patterns on both protein level and transcript level to construct DElncRNA-DEmRNA network. In addition, based on the DElncRNA-bmo-miR-278-3p-BmHSC70 regulatory network, we explored the potential function of several lncRNAs as sponges to inhibit the regulatory effect of bmo-278-3p on Bombyx mori heat shock protein cognate 70 (BmHSC70). Our finding suggests that lncRNAs play a role in the regulation of BmNPV proliferation by Hsp90.
