DV infection induced IFIT expression.

<p>Human DCs (A) or A549 cells (B, C, and D) at 1 х 10<sup>6</sup> or 1 х 10<sup>5</sup> cells/mL were infected by mock or DV at various time points. Total cell lysates were collected and the expression of IFIT3 or β-actin was determined by western blotting (A and B) or immunocytochemical staining (C). Expression of mRNAs of <i>ifit1</i>, <i>ifit2</i>, <i>ifit3</i>, and <i>ifit5</i> genes was determined by quantitative RT-PCR (D). The data shown are from 3 independent experiments. </p>
