Additional file 1: Figure S1. of Interleukin 12 shows a better curative effect on lung cancer than paclitaxel and cisplatin doublet chemotherapy

Analysis of lung tumor nodes and tumor lung tissues weight in the four treatment groups. (A) The LLC tumor nodes and lung tissues were photographed. The visible tumor nodes were counted, and the final lung tumor tissues were photographed after completion of the treatments. The tumor and lung tissues as a whole were weighed. The average visible lung tumor nodes and the weight of LLC tumor and lung tissues from the IL-12 or PTX + CDDP + IL-12 group were significantly less than those of the PTX or control group (n = 3; means ± SEM, **P < 0.01). (B) The CT26 tumor nodes and lung tissues were photographed. The visible tumor nodes were counted, and the final lung tumor tissues were photographed after completion of the treatments. The tumor and lung tissues as a whole were weighed. The average visible lung tumor nodes and the weight of CT26 tumor and lung tissues from the IL-12 or PTX + CDDP + IL-12 group were significantly less than those of the PTX or control group (n = 3; means ± SEM, **P < 0.01).
