Outline of Final Research Achievements |
Spheroid colony formation is a useful method of cancer stem cell characterization. We found that QPRT、CST2、ANKRD45、ZWINT、FAM111B gene is up-regulated in spheroid body-forming cancer cells compared with parental cells. We investigated ZWINT expression in colorectal cancer. Immunohistochemical analysis demonstrated that 61 (47%) of 129 colorectal cancer cases were positive for ZWINT and ZWINT expression was significantly correlated with KIFC1 expression. ZWINT-positive cases exhibited significantly worse overall survival. KIFC1 siRNA-transfected cells showed reduced ZWINT expression while ZWINT siRNA-transfected cells decreased cell proliferation. Both KIFC1 and ZWINT knockdown cells attenuated spheroid formation ability. This study provides new insights into KIFC1 regulating ZWINT in colorectal cancer progression and its potential as a therapeutic target.

Academic Significance and Societal Importance of the Research Achievements |
ZWINTは47%の大腸癌で高発現しおり、高発現例は有意に予後不良であったことから、大腸癌の予後予測マーカーとして有用である。さらにZWINTは癌幹細胞のマーカーであるKIFC1陽性細胞において発現していたことから、幹細胞において重要な役割を果たしている可能性もあり、治療標的としても期待される。
