| Outline of Final Research Achievements |
We found that the expression of JMJD3 was high in the normal mucosa and low in a cancer cell in colorectal cancer samples. Moreover, we found that the cases with high expression of JMJD3 were significantly better prognosis rather than with low expression of JMJD3 in cases of colorectal cancer performed radical resection. We confirmed that JMJD3 suppressed cell proliferation of colorectal cancer cell line controlling cell cycle and apoptosis through p15 in vitro. Moreover, we confirmed that cell proliferation of colon cancer cell line increased by JMJD3 knockdown using siRNA.
In addition, in the cases with colorectal liver metastasis who underwent hepatectomy after preoperative chemotherapy, the cases with high EZH2 expression was significantly worse prognosis rather than with low expression of EZH2. EZH2 was related to response of preoperative chemotherapy. We confirmed that chemosensitivity for oxaliplatin of colon cancer cell line increased by knockdown of EZH2 using siRNA.
