Interleukin-18 Is a Prognostic Marker and Plays a Tumor Suppressive Role in Colon Cancer

Figure 4

Effects of IL-18 on the proliferation of human colon cancer cells. RKO colon cancer cells were transfected with empty vector or plasmids coding for IL-18. The transfection efficiency was assessed by real-time PCR (a) and western blot (b). The effects of IL-18 overexpression on cell proliferation were evaluated with CCK-8 assays (c) and plate colony formation assays (d) ().
