Our previous study indicated that Aurora-B is involved in osteosarcoma (OS) cell invasion and metastasis; however, the mechanism underlying Aurora-B overexpression in OS remains unknown.
Aurora-B overexpression was found in 83 cases (53%) of NSCLC, and was significantly correlated with vascular invasion (p=0.012), poor differentiation (p<0.001), larger tumor size (p=0.010) and lymph node metastasis (p=0.05) and poor prognosis (p=0.011).
Furthermore, AURKB-Sv2 variant form is associated with a higher level of serum alpha-fetoprotein, protein induced by vitamin K absence or antagonist-II (PIVKAII), tumor capsular invasion, multiple tumor formation and at an age younger than those with other variant forms (P < 0.05).
