Patent number: 7871788Abstract: Means for easily determining the grade of malignancy of cancer cells. The amount of ATBF1 in the whole cell structure of test cancer cells separated from a living organism is detected, and on the basis of detection results, the grade of malignancy of test cancer cells is judged. Alternatively, the amount of ATBF1 in the nuclei of test cancer cells separated from a living organism is detected, and on the basis of detection results, the grade of malignancy of test cancer cells is judged. Still alternatively, the amount of ATBF1 in the cytoplasms of test cancer cells separated from a living organism is detected, and on the basis of detection results, the grade of malignancy of test cancer cells is judged.Type: GrantFiled: July 29, 2005Date of Patent: January 18, 2011Assignee: Nagoya Industrial Science Research InstituteInventors: Yutaka Miura, Makoto Kawaguchi, Hirotaka Iwase, Minoru Hamazaki, Jung Cha-Gyun, Hitoo Nishino
