Outline of Final Research Achievements

We analyzed aberrant crypt foci (ACF) tissues using microarray to find a specific molecule for molecular imaging of ACF. Then, we found Glutathione S-transferase(GST)-pi、EGFR, glut-1 are overexpressed in ACF as a specific molecule for ACF molecular imaging. Synthesizing fluorescent probe targeting GST-pi, EGFR and glut-1, we clearly identified ACF on the colorectal mucosa in azxymethane-injected mouse model under fluorescence microscope. We also clearly visualized human ACF on colorectal mucosa resected from patients with colorectal cancers under fluorescence microscope. Thus, we were able to detect human and rodent precancerous ACF lesions using molecular imaging technique.
