Outline of Final Research Achievements |
The purpose of this study is to clarify the mechanisms and clinical significance of KPC1 and NFκB dysregulation in colorectal cancer. Using colorectal cancer cell lines and KPC expression vector, overexpression of KPC1 significantly suppressed cell proliferation. Accordingly, immunohistochemical staining of KPC1 and NFκB p50 revealed that there are correlation between KPC1 and NFκB p50 expression or tumor depth. These results suggest that KPC1 is involved in NFκB p50 regulation and tumor depth/proliferation in colorectal cancer.

Academic Significance and Societal Importance of the Research Achievements |
今回得られた結果はpreliminaryなデータではあるものの、KPC1が大腸癌の増殖や深達度に関与していることが示唆された。今後これらに関与する下流のNFκBシグナルの変化、さらには抗癌剤抵抗性・放射線抵抗性等への影響の可能性など、基礎的な実験を継続しデータを収集していく。NFκB・KPC1を軸とした制御異常は大腸癌の細胞増殖・アポトーシス・血管新生・転移等複数のプロセスに影響を及ぼす重要な因子である可能性があり、引き続き研究を行う必要があると考える。
