Figure 2From: 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 Effect of I3C on basal ODC activity and cell number after 24 hours. ODC activity in cell lysates was determined as described in Materials and Methods. Results are expressed as a percentage of control values (n = minimum of 5; pooled SD of each set for ODC activity and cell number for each cell line are: SW480, 18.76, 11.38; HT29, 13.12, 4.11; HCEC, 15.22, 12.37 respectively). Significant difference from the control (DMSO treated) is indicated by * (P < 0.05).Back to article page
