| Research Abstract |
Chromosomal instability (CIN) that is one of the essential properties of tumor malignancy is associated with abnormal centrosome amplification and disturbed mitotic (M phase) checkpoint control, suggesting that certain centrosomal kinases cause induction of CIN. Furthermore, abnormal cell growth due to inability to enter the G0 phase is another important trait of cancer. In this study, we demonstrate that the centrosomal kinases, Lats1 and Lats2, control the mitotic checkpoint through centrosomal integrity and chromosomal segregation and prevent abnormal cell growth. These results suggest that Lats1/2 kinases comprise a novel signaling pathway which links G0 to M phases of the cell cycle.
