RFP dose-dependently decreased PRRSV nucleocapsid protein levels. (A,B) Marc-145 cells or PAMs were treated with the indicated concentrations of RFP for 24 h and the cell viability was examined by using the CCK8 kit. ***p < 0.001; ****p < 0.0001. (C,D) CC50 and IC50 were calculated using GraphPad Prism. (E–G) Marc-145 cells or PAMs were infected with PRRSV at an MOI of 0.1 after RFP treatment (indicated concentration). At 24 hpi, PRRSV replication was monitored by western blot (E,F) and immunofluorescence (G).
