Leader RNA facilitates snakehead vesiculovirus (SHVV) replication by interacting with CSDE1 and hnRNP A3
Leader RNAs are viral small non-coding RNAs that has been proved to play important roles in viral replication. Snakehead vesiculovirus (SHVV) is an aquatic virus that has caused huge economic loss in Chinese snakehead fish aquaculture industry. It has been proved that SHVV would generate leader RNA during the process of infection, and leader RNA could interact with viral nucleoprotein to promote viral replication. In this study, we identified that leader RNA could also interact with cellular protein Cold Shock Domain containing E1 (CSDE1) and heterogeneous nuclear ribonucleoproteins A3 (hnRNP A3). Further investigation reveals that overexpression of CSDE1 and hnRNP A3 facilitated SHVV replication. Downregulation of CSDE1 and hnRNP A3 by siRNA inhibited SHVV replication. This study provided a new sight into understand the mechanism of SHVV replication, and a potential anti-SHVV target for drug research.
期刊介绍：
Fish and Shellfish Immunology rapidly publishes high-quality, peer-refereed contributions in the expanding fields of fish and shellfish immunology. It presents studies on the basic mechanisms of both the specific and non-specific defense systems, the cells, tissues, and humoral factors involved, their dependence on environmental and intrinsic factors, response to pathogens, response to vaccination, and applied studies on the development of specific vaccines for use in the aquaculture industry.
