Figure 5: HMGB1 and Sirt1 are required to trigger ISG expression in DENV-infected cells.

(A,B) Huh7 WT and shHMGB1 cells were mock-infected or infected with DENV at an MOI of 1. Cells were harvested at 24 h p.i. and MxA (A) and ISG56 (B) mRNA were quantified using quantitative real-time RT-PCR, normalized to β-actin mRNA level. (C,D) Huh7 WT and shSirt1 cells were mock-infected or infected with DENV at an MOI of 1. Cells were harvested at 24 h p.i. and MxA (C) and ISG56 (D) mRNA were detected using RT-PCR. Statistically significant differences between the groups are indicated: *P < 0.05, **P < 0.01, ***P < 0.001.
