15-PGDH mRNA expression in normal and malignant colon. (A) 15-PGDH expression in normal colon and primary colon cancers of Dukes' stages B, C, and D, as measured on expression microarrays in average intensity (AI) units. Horizontal bars indicate median expression levels for normal colon versus all colon cancer samples. Twenty-five AI units represent null expression on the microarray. (B) Real-time PCR assay of 15-PGDH. Shown is the ratio of 15-PGDH expression in 20 colon cancers versus matched normal colon. Values represent averages of six replicates.
