FLT3L and granulocyte macrophage colony-stimulating factor enhance the anti-tumor and immune effects of an HPV16 E6/E7 vaccine
Figure 1. The efficiency of the HPV16 E6/E7 plasmids was validated by qRT-PCR and Western blotting. (A–D) The gene expression of pVAX1-IRES-GM-CSF-B7.1 (A), pVAX1-IRES-GM-CSF-B7.1-HPV16 E6/E7 (B), pIRES-neo3-HPV16 E6/E7 (C) and pVAX1-IRES-FLT3L (D) in B16 cells was detected by qRT-PCR. (E–H) The protein expression of pVAX1-IRES-GM-CSF-B7.1 (E), pVAX1-IRES-GM-CSF-B7.1-HPV16 E6/E7 (F), pIRES-neo3-HPV16 E6/E7 (G) and pVAX1-IRES-FLT3L (H) in B16 cells was detected by Western blotting. (I) FLT3L levels in B16 cells transfected with pVAX1-IRES-FLT3L were detected by ELISA. **P < 0.01 compared with the pVAX1-IRES or pIRES-neo3 group.
