gga-miR-200b-3p promotes avian leukosis virus subgroup J replication via targeting dual-specificity phosphatase 1
2021
MicroRNAs (miRNAs) involved host-virus interaction, affecting the replication or pathogenesis of several viruses. Although avian leukosis virus subgroup J (ALV-J) has been one of the most studied avian viruses, the effects of various host miRNAs on ALV-J infection and its underlying molecular mechanisms are still unclear. Here, we reported that gga-miR-200b-3p acts as a positive host factor enhancing ALV-J replication. We found that gga-miR-200b-3p was increased in response to ALV-J infection in host cells, and that gga-miR-200b-3p effectively enhanced ALV-J replication via targeting host protein dual-specificity phosphatase 1 (DUSP1). Collectively, these findings highlight a crucial role of gga-miR-200b-3p in ALV-J replication.
