UL38 promotes PRV replication in PK15 cells. PK15 cells were transfected with pCMV-Myc (1 µg) or Myc-UL38 (1 µg) infected with PRV (0.01 MOI) for 24 h, 36 h and 48 h. The supernatant was used to measure viral titers by TCID50 assay (A). The viral DNA was assessed by RT-qPCR (B). *p < 0.05. (C) STING blot (12, 24, and 36 h post infection) after UL38 + PRV and EV + PRV infection was detected by western blotting. β-actin served as a loading control
