Fig. 2. XPO1 inhibitor KPT-8602 inhibits the expression of KSHV genes except for LANA and vCyclin genes during primary infection.
A–L HUVEC were pretreated with 0.5 µM KPT-8602 for 1 h and then infected with KSHV in the presence of KPT-8602 for 4, 12, 24, 36, and 48 h. Cells were collected for RNA extraction and examined for the expression of KSHV transcripts by RT-qPCR. M HUVEC were pretreated with 0.5 µM KPT-8602 for 1 h and then infected with KSHV in the presence of KPT-8602. The cell lysate was collected at 4, 12, 24, and 48 hpi and analyzed for the expression of viral proteins by Western blotting. β-actin served as the loading control.
