  1. Data are obtained from our previous studies (Nakao et al, 1995; Uchida et al, 2004; Yoshitake et al, 2004; Taniuchi et al, 2005; Watanabe et al, 2005).
  2. aThe relative expression ratio was calculated by dividing the value of the expression of KIF20A mRNA in cancer cells by that in the normal counterpart, and a relative expression ratio (cancer/normal tissue) of >5 was considered to be positive.
