| Outline of Final Research Achievements |
We measured IDO expression level in patients with metastatic bladder cancer. However, no significant expression of IDO was observed in these patients. Then we measured IDO expression in patients with renal cell carcinoma. IDO was expressed in tumor vessels. In order to quantify the level of IDO expression, we performed quantitative PCR. We analyzed the expression level of IDO in 52 patients who underwent radical nephrectomy due to renal cell carcinoma. However, we could not find any significant correlation between IDO expression level and clinic-pathological features in these patients.
Next we established stable transformant ovarian cancer cell line expressing IDO by gene transduction. When this IDO over expressing cell line was inoculated into peritoneal cavity, they grew quickly comparing with parental cell line. Significant reduce of CD8 T cells and NK cells in tumor site was observed.
