  Molecular approach to cancer chemosensitivity

We have been investigating the chemosensitivity test, which is useful in evaluating the appropriate adjuvant cancer chemotherapy for advanced gastrointestinal carcinomas. It was repeatedly confirmed that the sensitive group had a favorable survival outcome compared with the resistant group. We have been also investigating the molecular biological chemosensitivity test using microarrays and RT-PCR. Dihydropyrimidine dehydrogenase expression, which is a rate-limiting catabolizing enzyme of 5-FU, has been repeatedly determined to be the resistance-related gene to 5-FU. Our present interest is to overcome tumor chemoresistance by targeting the resistance-causal genes.
