The phoP/phoQ(pcDNA3.1- L1-siE6) can inhibit the growth of the xenograft tumors in vivo. (A) The map of pcDNA3.1- L1-siE6. (B,C) Growth of Siha xenografts treated with attenuated Salmonella phoP/phoQ. Each treatment with the plasmid is shown an arrow. **P < 0.01, vs the two control groups. (D) H&E analysis of Siha xenografts treated with phoP/phoQ (× 400).
