MicroRNA (miRNA) 已成为宿主与病原体相互作用的关键参与者,并且已在多种生物体中(通过计算和/或实验)鉴定出许多病毒编码的 miRNA。先前通过高通量测序鉴定出一种新型家蚕核多角体病毒 (BmNPV) 编码的 miRNA miR-415。本研究构建了BmNPV-miR-415表达载体并转染至BmN细胞中。通过二维凝胶电泳和质谱观察雷帕霉素亚型2(TOR2)的差异表达蛋白靶点。结果表明,TOR2并不是BmNPV-miR-415的直接靶基因,但其表达可被BmNPV-miR-415通过Bmo-miR-5738上调,并可被BmNPV诱导。
MicroRNAs (miRNAs) have emerged as key players in host–pathogen interaction and many virus-encoded miRNAs have been identified (computationally and/or experimentally) in a variety of organisms. A novel Bombyx mori nucleopolyhedrosis virus (BmNPV)-encoded miRNA miR-415 was previously identified through high-throughput sequencing. In this study, a BmNPV-miR-415 expression vector was constructed and transfected into BmN cells. The differentially expressed protein target of rapamycin isoform 2 (TOR2) was observed through two-dimensional gel electrophoresis and mass spectrometry. Results showed that TOR2 is not directly a target gene of BmNPV-miR-415, but its expression is up-regulated by BmNPV-miR-415 via Bmo-miR-5738, which could be induced by BmNPV.
