Effect of soy saponin on the growth of human colon cancer cells

Figure 7 Effect of crude soybean saponins extracted on c-Jun (46 kDa) expression of WiDr cells. C+T: Control culture + 100 ng/mL tetradecanoyl phorbol-13-acetate (TPA); C-T: Untreated control culture for 3 d; S150: Culture exposed to 150 ppm extracted crude soybean saponins + 100 ng/mL TPA for 3 d; S300: 300 ppm; S600: 600 ppm; S1200: 1200 ppm. Values are mean ± SD. Different concentrations of saponin at each incubation time were compared using one way analysis of variances with Fisher’s test. Bars with letter “a” represent significant differences at the P < 0.05 level.
