ERK MAPK pathway partially contributes to HSV-1-induced KSHV replication. (A) Western blot analysis was used to detect the expression of KSHV Rta, vIL-6 and phosphorylated ERK in MEK-DN or control vector transfected and HSV-1 infected BCBL-1 cells as indicated. (B) Real-time DNA-PCR was used to detect the copy number of KSHV progeny virions in the supernatant of MEK-DN or control vector transfected and HSV-1 infected BCBL-1 cells as indicated. ** p < 0.01 and ## p < 0.01 for Student's t-test versus Mock + pcDNA and HSV-1 + pcDNA groups, respectively. (C) RT-qPCR was used to detect relative quantities of ORF26 mRNA in peptide II pretreated, HSV-1 infected BCBL-1 cells as indicated. *** p < 0.001 for Student's t-test versus Mock + H2O group; # p < 0.05 and ## p < 0.01 for Student's t-test versus HSV-1 + H2O group. (D) KSHV lytic proteins ORF59 expression in peptide II pretreated, HSV-1 48 h infected BCBL-1 cells was detected by IFA staining with ORF59 mAb. Original magnifications, × 10. (E) Quantification of results in D. ** P < 0.01 and # P < 0.05 for Student's t-test versus Mock + H2O and HSV-1 + H2O groups, respectively.
