Outline of Final Research Achievements

The followings were revealed in this study: (1) Abnormality of a part of DNA repair gene is associated with centrosome amplification. (2) SASS6 overexpression is associated with centrosome amplification, mitotic chromosomal abnormalities, chromosome instability, and a poor prognosis in patients with colorectal cancer. (3) Overexpression of a SGOL1 splicing variant type B (SGOL1-B) is associated with centrosome amplification, abnormal mitosis, and resistance to taxane in non-small cell lung cancer. (4) Amplification of STK15(AURAK)gene which is involved in the centrosome regulation is a predictor of a poor prognosis in patients with gastric cancer. (5) Abnormal expressions of DNA glycosylase genes NEIL1, NEIL2, and NEIL3 are associated with somatic mutation loads in human cancer.
