FIG. 2.

Several chemokines are upregulated by EBV Zta or Rta in NPC cells. (A) EBV-negative NPC-TW01 cells were transfected with the indicated plasmids (vector or plasmids expressing Zta or Rta), and the expression of Zta, Rta and β-actin was examined in an immunoblotting assay. The expression profiles of chemokines in the cell culture supernatants were analyzed by using an antibody array. Compared to the vector control experiments, the Zta-upregulated (B) and Rta-upregulated (C) chemokines are also indicated.
