Supplemental Figure 5 from Herbacetin Is a Novel Allosteric Inhibitor of Ornithine Decarboxylase with Antitumor Activity

The effect of herbacetin on AP-1 upstream proteins. Colon cancer cells were treated with herbacetin for 48 h and expression of total and phosphorylated ERKs and RSK and total ODC was determined by Western blotting. Beta-Actin was used as a loading control. Similar results were obtained from 3 independent experiments and representative blots are shown.
