Figure 1From: Growth-inhibitory effects of the chemopreventive agent indole-3-carbinol are increased in combination with the polyamine putrescine in the SW480 colon tumour cell line Inhibition of cell growth by I3C. Cells were treated with I3C and counted at 24 hourly intervals as described in Materials and Methods. Results are presented as mean ± SEM (n = 6), * indicates significant difference from control cell numbers at that time point (P < 0.05).Back to article page
